We examined profiles of sibling relationship qualities in 246 Mexican-origin families living in the United States using latent profile analyses. Three profiles were identified: Positive, Negative and Affect-Intense. Links between profiles and youths’ familism values and adjustment were assessed using longitudinal data. Siblings in the Positive profile reported the highest familism values, followed by siblings in the Affect-Intense profile and, finally, siblings in the Negative profile. Older siblings in the Positive and Affect-Intense profiles reported fewer depressive symptoms than siblings in the Negative profile. Further, in the Positive and Negative profiles, older siblings reported less involvement in risky behaviors than younger siblings. In the Negative profile, younger siblings reported greater sexual risk behaviors in late adolescence than older siblings; siblings in opposite-sex dyads, as compared to same-sex dyads, engaged in riskier sexual behaviors. Our findings highlight sibling relationship quality as promotive and risky, depending on sibling characteristics and adjustment outcomes. PMID:28239217

Assessing the relationship between quality of life and behavioral activation using the Japanese Behavioral Activation for Depression Scale-Short Form.

PubMed

Shudo, Yusuke; Yamamoto, Tatsuya

2017-01-01

Quality of life (QOL) is an important health-related concept. Identifying factors that affect QOL can help develop and improve health-promotion interventions. Previous studies suggest that behavioral activation fosters subjective QOL, including well-being. However, the mechanism by which behavioral activation improves QOL is not clear. Considering that QOL improves when depressive symptoms improve post-treatment and that behavioral activation is an effective treatment for depression, it is possible that behavioral activation affects QOL indirectly rather than directly. To clarify the mechanism of the influence of behavioral activation on QOL, it is necessary to examine the relationships between factors related to behavioral activation, depressive symptoms, and QOL. Therefore, we attempted to examine the relationship between these factors. Participants comprised 221 Japanese undergraduate students who completed questionnaires on behavioral activation, QOL, and depressive symptoms: the Japanese versions of the Behavioral Activation for Depression Scale-Short Form (BADS-SF), WHO Quality of Life-BREF (WHOQOL-26), and Center for Epidemiologic Studies Depression Scale (CES-D). The BADS-SF comprises two subscales, Activation and Avoidance, and the WHOQOL-26 measures overall QOL and four domains, Physical Health, Psychological Health, Social Relationships, and Environment. Mediation analyses were conducted with BADS-SF activation and avoidance as independent variables, CES-D as a mediator variable, and each WHO-QOL as an outcome variable. Results indicated that depression completely mediated the relationship between Avoidance and QOL, and partially mediated the relationship between Activation and QOL. In addition, analyses of each domain of QOL showed that Activation positively affected all aspects of QOL directly and indirectly, but Avoidance had a negative influence on only part of QOL mainly through depression. The present study provides behavioral activation strategies aimed at QOL enhancement.

Premenstrual dysphoric disorder (PMDD) affects 5 to 8 percent of women and can significantly decrease their quality of life. Symptoms generally present during the late luteal phase of the menstrual cycle and can affect women emotionally, behaviorally, cognitively and physiologically. This article reviews the clinical literature on PMDD and the evidence behind various methods of symptom management. Evidence suggests that a holistic approach, including lifestyle modifications, pharmacotherapy and cognitive behavioral therapy, is most beneficial for symptom reduction and improvement in daily functioning and quality of life. © 2013 AWHONN.

Mechanisms Underlying the Influence of Disruptive Child Behavior on Interparental Communication

PubMed Central

Wymbs, Brian T.

2012-01-01

Prospective and experimental manipulations of child behavior have demonstrated that disruptive child behavior causes interparental discord. However, research has yet to test for mechanisms underlying this causal pathway. There is reason to suspect parent affect and parenting behavior explain child effects on interparental relations. To investigate this hypothesis, parent couples of 9- to 12-year-old boys and girls with attention-deficit/hyperactivity disorder (ADHD; n=51) and without ADHD (n=39) were randomly assigned to interact with a confederate child exhibiting “disruptive” or “typical” behavior. Parents rated their own affect as well as the quality of their partner's parenting and communication immediately following the interaction. Observers also coded the quality of parenting and communication behaviors parents exhibited during the interaction. Parents who interacted with disruptive confederates reported lower positive affect and higher negative affect than those who interacted with typical confederates. Parents were also noted by their partners and observers to parent disruptive confederates more negatively than typical confederates. Multilevel mediation models with observational coding and partner ratings both found that negative parenting explained the causal pathway between disruptive child behavior and negative communication. Exploratory analyses revealed that the strength of this pathway did not differ between parents of children with and without ADHD. Parent affect was not found to explain child effects on interparental communication. Though methodological issues limit the generalizability of these findings, results indicate that negative parenting may be one mechanism through which disruptive children cause interparental discord.

Harrison, Tondi M; Ferree, Allison

2014-12-01

The quality of maternal-infant interaction is a critical factor in the development of infants' autonomic function and social engagement skills. In this secondary data analysis, relationships among infant and maternal affect and behavior and quality of dyadic interaction, as measured by the Parent-Child Early Relational Assessment, and infant autonomic function, as measured by heart rate variability, were examined during feeding at 2 weeks and 2 months of age in 16 healthy infants and in 15 infants with transposition of the great arteries (TGA). Contrary to previous research, at 2 weeks infant age, mothers of infants with TGA had significantly higher scores in affect and behavior than did mothers of healthy infants. The affect and behavior and quality of dyadic interaction of infants with TGA also did not differ from that of healthy infants. Although infants' social engagement skills did not differ by health condition (TGA or healthy), these skills did differ by parasympathetic nervous system function: infants better able to suppress vagal activity with challenge had more positive and less dysregulated affect and behavior, regardless of health status. These findings suggest that maternal-infant interactions for some cardiac disease subgroups may not differ from healthy dyads. Additional research is required to identify both healthy and ill infants with delayed autonomic maturation and to develop and test interventions to enhance critical interactive functions. © 2014 Wiley Periodicals, Inc.

Mechanisms linking employee affective delivery and customer behavioral intentions.

Tsai, Wei-Chi; Huang, Yin-Mei

2002-10-01

Past empirical evidence has indicated that employee affective delivery can influence customer reactions (e.g., customer satisfaction, service quality evaluation). This study extends previous research by empirically examining mediating processes underlying the relationship between employee affective delivery and customer behavioral intentions. Data were collected from 352 employee-customer pairs in 169 retail shoe stores in Taiwan. Results showed that the influence of employee affective delivery on customers' willingness to return to the store and pass positive comments to friends was indirect through the mediating processes of customer in-store positive moods and perceived friendliness. The study also indicated that employee affective delivery influences customers' time spent in store, which, in turn, influences customer behavioral intentions.

Perceptions of physical appearance, or body image, can affect psychosocial functioning and quality of life (QOL). The present study evaluated the real-world predictive validity of the Body Image Quality of Life Inventory (BIQLI) using Ecological Momentary Assessment (EMA). College women reporting subclinical disordered eating/body dissatisfaction (N=131) completed the BIQLI and related measures. For one week they then completed five daily EMA surveys of mood, social interactions, stress, and eating behaviors on palmtop computers. Results showed better body image QOL was associated with less negative affect, less overwhelming emotions, more positive affect, more pleasant social interactions, and higher self-efficacy for handling stress. Lower body image QOL was marginally related to less overeating and lower loss of control over eating in daily life. To our knowledge, this is the first study to support the real-world predictive validity of the BIQLI by identifying social, affective, and behavioral correlates in everyday life using EMA.

Lacking quality in research: Is behavioral neuroscience affected more than other areas of biomedical science?

PubMed

Bespalov, Anton; Steckler, Thomas

2018-04-15

There are many reasons why novel therapeutics fail in clinical trials but these failures are often attributed to lacking quality of preclinical data. These problems are not limited to any specific therapeutic area, academic or industrial research and are due in large part to several generic factors influencing research quality (e.g., related to definition of pre-specified endpoints, principles of study design and analysis, biased reporting, and lack of proper training). Yet, neuroscience drug discovery is often said to be affected more than the other fields. Within neuroscience, behavioral studies are the most blamed for being poorly designed, underpowered and mis-reported and there are indeed several factors that may be rather unique for behavioral research, such as a multitude of environmental conditions that are difficult to control and that are often not reported, ethical concerns about in vivo research and the pressure to reduce animal numbers, contributing to under-powered studies, and the complexity of study design and analysis, creating too much room for post hoc data massaging and selective reporting. Also, the blood-brain barrier as a frequently neglected complicating factor has to be considered in CNS research. The importance of these factors is increasingly recognized and urgent efforts are needed to demonstrate that behavioral methods of preclinical neuroscience research deliver results that can be as robust as with the non-behavioral methods Until this goal is achieved, behavioral neuroscience and neuroscience in general may be losing young talent, CNS drug discovery may lack the needed investment and this field may indeed be amongst the most affected by the current preclinical data quality crisis.

The Longitudinal Association Between Poor Sleep Quality and Cyberbullying, Mediated by Anger.

PubMed

Erreygers, Sara; Vandebosch, Heidi; Vranjes, Ivana; Baillien, Elfi; De Witte, Hans

2018-01-09

Adolescents tend to go to bed later and sleep less as they grow older, although their need for sleep stays the same throughout adolescence. Poor sleep has negative consequences on personal and interpersonal functioning, including increased aggressive tendencies. With adolescents' social life increasingly including interactions via digital media, these interactions may also become more aggressive when adolescents' sleep problems increase. One of the ways in which online aggression may be enacted is through cyberbullying. Although previous research has examined the role of sleep disruptions in offline bullying, the role of sleep in cyberbullying has not yet been addressed. Therefore, this study examines the longitudinal effect of poor sleep quality on later cyberbullying behavior. Thirteen- to fourteen-year-old adolescents completed self-report measures on sleep quality, anger, cyberbullying perpetration, and frequency of digital media use. Because one of the pathways through which sleep is proposed to be linked to aggression is an affective pathway, namely via angry affect, a mediation model of poor sleep quality predicting cyberbullying via feelings of anger was tested. Results from structural equation modeling and a bootstrap test indicated that poor sleep quality was indeed indirectly associated with later cyberbullying behavior through heightened feelings of anger, even when taking the effects of the use of digital media and previous cyberbullying behavior into account. This finding provides support for the proposed affective pathway linking sleep problems to aggression. As sleep problems and anger seem to play a predicting role in cyberbullying behavior, suggestions for cyberbullying intervention and prevention strategies are formulated.

Determining possible associated factors and the influencing pathways to hemoglobin A1C (HbA1C) levels and quality of life (QoL) will facilitate the development of effective interventions to improve the physical and psychosocial health of patients with type 2 diabetes mellitus (T2DM). To test a hypothesized model that addressed the pathways among personal characteristics, social support, diabetes distress, and self-care behaviors to HbA1C and QoL. A total of 382 adults with T2DM were recruited. Self-reported questionnaires and medical records were used to collect data regarding personal characteristics, diabetes distress, and social support at baseline. The self-care behaviors characters were collected 6 months later, as well as QoL and HbA1C levels 1 year later. The 12-month QoL directly affected 12-month HbA1C levels. The 6-month self-care behaviors directly affected 12-month QoL, and indirectly affected 12-month HbA1C levels through 12-month QoL. Baseline diabetes distress directly affected 12-month QoL. Moreover, baseline diabetes distress indirectly affected 12-month HbA1C levels through 12-month QoL. Baseline social support directly affected baseline diabetes distress and 6-month self-care behaviors. In addition, baseline social support indirectly affected 12-month QoL through baseline diabetes distress. Baseline social support also indirectly affected 12-month QoL through 6-month self-care behaviors. Enhancing QoL is important to improve HbA1C levels. Enhancing self-care behaviors is essential to improve subsequent HbA1C control and QoL. Reducing diabetes distress is crucial to improve subsequent QoL. Improving social support is suggested a favorable strategy to reduce diabetes distress and enhance subsequent self-care behaviors in patients with T2DM. © 2018 Sigma Theta Tau International.

2016-02-01

This study explored the association of engagement in pleasant events and global sleep quality, as well as examined the intermediary roles of positive affect and depressive symptoms in this association. Data were derived from the Midlife in the United States-II study. The sample consisted of 1054 community-dwelling adults. Participants completed the Pittsburgh Sleep Quality Index and indicated the frequency and enjoyableness of experiences on a positive events scale. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale. Positive affect was measured using the Mood and Symptoms Questionnaire. Regression analyses indicated more frequent engagement in pleasant events was associated with better global sleep quality. Depressive symptoms, but not positive affect, partially mediated the association between pleasant events and global sleep quality. The findings suggest that behavioral engagement in pleasant events may be related to global sleep quality via depressive symptoms, but not positive affect. These findings highlight the potential for engagement in pleasant activities to influence both mood and sleep.

Somatic-Affective, But Not Cognitive-Depressive Symptoms are Associated With Reduced Health-Related Quality of Life in Patients With Congestive Heart Failure.

Patron, Elisabetta; Messerotti Benvenuti, Simone; Lopriore, Vincenzo; Aratari, Jenny; Palomba, Daniela

Depression has been associated with poor health-related quality of life (HRQoL) in patients with congestive heart failure (CHF). However, to date, whether somatic-affective and cognitive-depressive symptoms differently contribute to poor HRQoL and behavioral functional capacity in patients with CHF has yet to be investigated. To examine the differential influence of somatic-affective vs cognitive-depressive symptoms on HRQoL and behavioral functional capacity in CHF patients. Overall, 55 patients with CHF completed a psychologic evaluation, including the Minnesota Living with Heart Failure Questionnaire, the Beck Depression Inventory-II, and the Beck Anxiety Inventory for HRQoL, depressive, and anxiety symptoms, respectively. The patients completed the Instrumental Activities of Daily Living Questionnaire and the 6-minute walk test for behavioral functional capacity. Hierarchical regression analyses were used to predict HRQoL and behavioral functional capacity from Beck Depression Inventory-II and Beck Anxiety Inventory scores. Somatic-affective depressive symptoms were associated with physical (β = 0.37, p = 0.005) and emotional (β = 0.39, p = 0.008) Minnesota Living with Heart Failure Questionnaire subscale scores. Likewise, somatic-affective depressive symptoms predicted Instrumental Activities of Daily Livings Scores (β = 0.43, p = 0.004) and distance ambulated during the 6-minute walk test (β = -0.36, p = 0.029). By contrast, cognitive-depressive symptoms and anxiety were unrelated to HRQoL and behavioral functional capacity (all p > 0.05). These findings showed that somatic-affective depressive symptoms, but not cognitive-depressive symptoms and anxiety, are associated with poor HRQoL and behavioral functional capacity independent of age, clinical functional status, and medical comorbidities. This study suggests that patients with CHF with somatic-affective rather than cognitive-depressive symptoms or anxiety may be at greater risk of poor HRQoL and behavioral functional capacity.

Recognizing how human behaviors affect the milk process can be useful to understand variations in hygienic and sanitary parameters in bulk tank milk. Furthermore, this knowledge could be used to design management programs that guarantee milk quality, favoring the optimization of such processes. Forty-six milkers from the same number of dairy farms in Antioquia province (Colombia) were interviewed to establish the main factors associated to milk quality. Technical knowledge, motivations, and behavior of the personnel and its effect on hygienic and sanitary quality of milk were evaluated. Quality was assessed in terms of colony-forming units (CFU) and somatic cell count (SCC) in bulk tank milk. Two factors from a multivariate mixed data analysis were evaluated. One of those factors explained 9.51% of the total variability, related with in-farm availability and use of tools and the relationships between milker and manager. The other factor, associated with work environment and recognition, explained 6.97% of the total variability. The variables that best explained CFU levels were Knowledge of the udder condition at milking, and Milking type (parlor or pasture). The SCC was associated to knowledge of animal handling, schooling of milkers, milking site, and the groups derived from the cluster analysis by farm. In conclusion, milker attitudes and behaviors can affect CFU and SCC in bulk tank milk. PMID:28926583

Religious participation is linked to overall satisfaction among both married and unmarried couples in urban America. Less is known about what may account for the association between religious participation and relationship quality. We explore this issue using data from the first two waves of the Fragile Families and Child Wellbeing Study. Relationship-related behaviors (e.g., temperance) and relationship-specific behaviors (e.g., affection) can each account for the association between church attendance and relationship quality. Furthermore, religious participation appears to be more tightly linked to men's perceptions of relationship quality than women's. PMID:18784851

Cerebellar ataxia comprises a group of debilitating diseases that are the result of progressive cerebellar degeneration. Recent studies suggest that, like other neurodegenerative diseases, sleep impairments are common in cerebellar ataxia. In light of the role of sleep in mood regulation and cognition, we sought to assess interactions between sleep, cognition, and affect in individuals with cerebellar ataxia. A survey of 176 individuals with cerebellar ataxia was conducted. The battery of instruments included a modified International Cooperative Ataxia Rating Scale, Pittsburgh Sleep Quality Index, Restless Leg Syndrome Questionnaire, REM Behavior Disorder Questionnaire, Beck Depression Inventory, Epworth Sleepiness Scale, and a Composite Cognitive Questionnaire. Fifty-one percent of individuals indicated significant sleep disturbances on the Pittsburgh Sleep Quality Index, 73% of participants had two or more symptoms of restless leg syndrome, and 88% had two or more symptoms of REM behavior disorder. Ataxia severity, based on the modified International Cooperative Ataxia Rating Scale, predicted scores on the Pittsburgh Sleep Quality Index, the Epworth Sleepiness Scale and REM Behavior Disorder Questionnaire. Median split analyses revealed that cognitive function appeared to be reduced and depressive symptoms were greater for those individuals with poor subjective sleep quality and severe RLS. Importantly, sleep appears to play a mediatory role between disease severity and depressive symptoms. These results suggest that disturbed sleep may have detrimental effects on cognition and affect in individuals with cerebellar ataxia. While objective measures are needed, such results suggest that treating sleep deficits in these individuals may improve cognitive and mental health as well as overall quality of life.

Maltreatment and Affective and Behavioral Problems in Emerging Adults With and Without Oppositional Defiant Disorder Symptoms: Mediation by Parent-Child Relationship Quality.

McKinney, Cliff; Stearns, Melanie; Szkody, Erica

2018-03-01

The current study examined the indirect effect of maternal and paternal emotional and physical maltreatment on affective and behavioral symptoms of oppositional defiant disorder (ODD) through parent-child relationship quality; gender and overall ODD symptoms were examined as moderators. Participants included 2,362 emerging adults who completed questionnaires about parental emotional and physical maltreatment, parent-child relationship quality, and affective and behavioral ODD symptoms. These characteristics were compared across parent and child gender (i.e., maternal and paternal effects as well as male and female differences) as well as participants reporting high and low ODD symptoms. In the low ODD group, indirect effects of emotional maltreatment occurred in all parent-child dyads except the mother-son dyad, whereas in the high ODD group, indirect effects occurred only in the father-son dyad. Indirect effects of physical maltreatment occurred only in the father-son dyad in the low ODD group, and only in the mother-daughter dyad on behavioral ODD symptoms in the high ODD group. The results suggest that specific parent-child gender dyads respond differently, warranting further investigation of gender effects. Moreover, emerging adults in the low ODD symptoms group demonstrated a positive association between parental maltreatment and ODD symptoms and a negative association between parent-child relationship quality and ODD symptoms, whereas those high in the high ODD symptoms group did not demonstrate these associations. That is, emerging adults reporting high ODD symptoms demonstrated no relationship between their ODD symptoms and harsh parenting, suggesting an ineffective coercive process.

Chamber QoE: a multi-instrumental approach to explore affective aspects in relation to quality of experience

Evaluating (audio)visual quality and Quality of Experience (QoE) from the user's perspective, has become a key element in optimizing users' experiences and their quality. Traditionally, the focus lies on how multi-level quality features are perceived by a human user. The interest has however gradually expanded towards human cognitive, affective and behavioral processes that may impact on, be an element of, or be influenced by QoE, and which have been underinvestigated so far. In addition, there is a major discrepancy between the new, broadly supported and more holistic conceptualization of QoE proposed by Le Callet et al. (2012) and traditional, standardized QoE assessment. This paper explores ways to tackle this discrepancy by means of a multi-instrumental approach. More concretely, it presents results from a lab study on video quality (N=27), aimed at going beyond the dominant QoE assessment paradigm and at exploring affective aspects in relation to QoE and in relation to perceived overall quality. Four types of data were collected: `traditional' QoE self-report measures were complemented with `alternative', emotional state- and user engagement-related self-report measures to evaluate QoE. In addition, we collected EEG (physiological) data, gazetracking data and facial expressions (behavioral) data. The video samples used in test were longer in duration than is common in standard tests allowing us to study e.g. more realistic experience and deeper user engagement. Our findings support the claim that the traditional QoE measures need to be reconsidered and extended with additional, affective staterelated measures.

Ventromedial prefrontal cortex supports affective future simulation by integrating distributed knowledge

PubMed Central

Benoit, Roland G.; Szpunar, Karl K.; Schacter, Daniel L.

2014-01-01

Although the future often seems intangible, we can make it more concrete by imagining prospective events. Here, using functional MRI, we demonstrate a mechanism by which the ventromedial prefrontal cortex supports such episodic simulations, and thereby contributes to affective foresight: This region supports processes that (i) integrate knowledge related to the elements that constitute an episode and (ii) represent the episode’s emergent affective quality. The ventromedial prefrontal cortex achieves such integration via interactions with distributed cortical regions that process the individual elements. Its activation then signals the affective quality of the ensuing episode, which goes beyond the combined affective quality of its constituting elements. The integrative process further augments long-term retention of the episode, making it available at later time points. This mechanism thus renders the future tangible, providing a basis for farsighted behavior. PMID:25368170

Health-related Quality of Life and the Impact of Childhood Neurologic Disability Scale were collected for 53 patients with CHARGE syndrome aged 13-39 years with a mean academic level of 4th grade. The most prevalent new and ongoing issues included bone health issues, sleep apnea, retinal detachment, anxiety, and aggression. Sleep issues were significantly correlated with anxiety, self-abuse, conduct problems, and autistic-like behaviors. Problems with overall health, behavior, and balance most affected the number of social activities in the individual's life. Sensory impairment most affected relationships with friends. Two contrasting case studies are presented and demonstrate that the quality of life exists on a broad spectrum in CHARGE syndrome, just as its physical features range from mild to very severe. A multitude of factors, including those beyond the physical manifestations, such as anxiety and sleep problems, influence quality of life and are important areas for intervention. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Self-regulation as a mediator between sibling relationship quality and early adolescents' positive and negative outcomes.

PubMed

Padilla-Walker, Laura M; Harper, James M; Jensen, Alexander C

2010-08-01

The current study examined the role of adolescents' self-regulation as a mediator between sibling relationship quality and adolescent outcomes, after controlling for the quality of the parent-child relationship. Participants were 395 families (282 two parent; 113 single parent) with an adolescent child (M age of child at Time 1 = 11.15, SD = .96, 49% female) who took part in [project name masked for blind review] at both Time 1 and Time 2. Path analysis via structural equation modeling suggested that sibling affection was longitudinally and positively related to self-regulation and prosocial behaviors, and negatively related to externalizing behaviors; while sibling hostility was positively, and having a sister was negatively related to internalizing behaviors (in general, paths were stronger for adolescents from two- vs. single-parent families). There was also evidence that adolescents' self-regulation partially mediated the relation between sibling affection and positive and negative adolescent outcomes. The discussion focuses on the importance of continued research examining the mechanisms through which the sibling relationship influences development during adolescence.

The Early Mother-to-Child Bond and Its Unique Prospective Contribution to Child Behavior Evaluated by Mothers and Teachers.

PubMed

Fuchs, Anna; Möhler, Eva; Reck, Corinna; Resch, Franz; Kaess, Michael

Maternal bonding has been described as the quality of the affective tie from a mother to her infant. This early bond's mental components and its longitudinal impact on child outcome have been markedly understudied. Although most researchers assume impaired maternal bonding to have a negative impact on child development, there is a lack of prospective studies evaluating this hypothesis. Since maternal mental health problems may negatively affect both bonding quality and child development, it is still to be determined whether there is a unique contribution of bonding quality to child behavior problems over and above maternal psychopathology. We examined a community sample of 101 mother-child dyads at the child's age of 2 weeks (t1) and 6 weeks (t2), 4 months (t3), 14 months (t4), and 5.5 years (t5). Maternal bonding and psychopathology were assessed at time points t1-t4 using the Postpartum Bonding Questionnaire (PBQ-16) and the Symptom Checklist Revised (SCL 90-R). Child behavior problems were rated in a multi-informant design by mothers and teachers at t5 using the Strengths and Difficulties Questionnaire (SDQ). In the case of maternal judgment of child behavior problems, bonding at 14 months (t4) proved to be a significant predictor (β = 0.30; p = 0.011). Teacher-rated child behavior problems were significantly predicted by maternal bonding at 2 weeks (t1; β = 0.48; p = 0.025). Our results indicate a prospective influence of the early mother-infant bond on child development and underline the unique contribution of bonding quality to child behavior problems over and above the impact of maternal psychopathology in a community sample. © 2016 S.

Matrix quality and disturbance frequency drive evolution of species behavior at habitat boundaries.

Martin, Amanda E; Fahrig, Lenore

Previous theoretical studies suggest that a species' landscape should influence the evolution of its dispersal characteristics, because landscape structure affects the costs and benefits of dispersal. However, these studies have not considered the evolution of boundary crossing, that is, the tendency of animals to cross from habitat to nonhabitat ("matrix"). It is important to understand this dispersal behavior, because of its effects on the probability of population persistence. Boundary-crossing behavior drives the rate of interaction with matrix, and thus, it influences the rate of movement among populations and the risk of dispersal mortality. We used an individual-based, spatially explicit model to simulate the evolution of boundary crossing in response to landscape structure. Our simulations predict higher evolved probabilities of boundary crossing in landscapes with more habitat, less fragmented habitat, higher-quality matrix, and more frequent disturbances (i.e., fewer generations between local population extinction events). Unexpectedly, our simulations also suggest that matrix quality and disturbance frequency have much stronger effects on the evolution of boundary crossing than either habitat amount or habitat fragmentation. Our results suggest that boundary-crossing responses are most affected by the costs of dispersal through matrix and the benefits of escaping local extinction events. Evolution of optimal behavior at habitat boundaries in response to the landscape may have implications for species in human-altered landscapes, because this behavior may become suboptimal if the landscape changes faster than the species' evolutionary response to that change. Understanding how matrix quality and habitat disturbance drive evolution of behavior at boundaries, and how this in turn influences the extinction risk of species in human-altered landscapes should help us identify species of conservation concern and target them for management.

Zada, Gabriel; Kintz, Natalie; Pulido, Mario; Amezcua, Lilyana

2013-01-01

Background Craniopharyngiomas (CP) are locally invasive and frequently recurring neoplasms often resulting in neurological and endocrinological dysfunction in children. In addition, social-behavioral impairment is commonly reported following treatment for childhood CP, yet remains to be fully understood. The authors aimed to further characterize the prevalence of neurobehavioral, social, and emotional dysfunction in survivors of childhood craniopharyngiomas. Materials and Methods A systematic literature review was conducted in PubMed to identify studies formally assessing neurobehavioral, social, and emotional outcomes in patients treated for CP prior to 18 years of age. Studies published between the years 1990-2012 that reported the primary outcome (prevalence of neurobehavioral, social, emotional/affective dysfunction, and/or impaired quality of life (QoL)) in ≥10 patients were included. Results Of the 471 studies screened, 11 met inclusion criteria. Overall neurobehavioral dysfunction was reported in 51 of 90 patients (57%) with available data. Social impairment (i.e. withdrawal, internalizing behavior) was reported in 91 of 222 cases (41%). School dysfunction was reported in 48 of 136 patients (35%). Emotional/affective dysfunction was reported in 58 of 146 patients (40%), primarily consisting of depressive symptoms. Health related quality of life was affected in 49 of 95 patients (52%). Common descriptors of behavior in affected children included irritability, impulsivity, aggressiveness, and emotional outbursts. Conclusions Neurobehavioral, social, and emotional impairment is highly prevalent in survivors of childhood craniopharyngioma, and often affects quality of life. Thorough neurobehavioral/emotional screening and appropriate counseling is recommended in this population. Additional research is warranted to identify risk factors and treatment strategies for these disorders. PMID:24223703

Patients with heart failure experience adverse physical symptoms that affect quality of life. The number of patients with heart failure in Taiwan has been growing in recent years. This article examines correlations among illness knowledge, self-care behaviors, and quality of life in elderly patients with heart failure. A cross-sectional research design using three questionnaires was adopted. The study was undertaken in an outpatient department of a teaching hospital in Taiwan from January to June 2008. Potential participants aged 65 years or older were selected by a physician based on several diagnostic findings of heart failure that included an International Classification of Diseases' code 4280 or 4289. Patients who were bedridden or had a prognosis of less than 6 months were excluded from consideration. One hundred forty-one patients with heart failure were recruited. Most participants were men (51.8%), older adults (49.6% older than 71 years old), and either educated to an elementary school level or illiterate (69.5%) and have New York Heart Association class II (61.0%). Participants had an average left ventricular ejection fraction of 41.1%. The illness knowledge of participants was poor (accuracy rate: 29.3%), and most were unaware of the significance of self-care. Illness knowledge correlated with both self-care behaviors (r = -.42, p < .01) and quality of life (r = -.22, p < .01). Illness knowledge and age were identified as significant correlated factors of self-care behaviors (R = .22); and functional class, living independently, and age were identified as significant correlated factors of quality of life (R = .41). Participants in this study with higher self-reported self-care behaviors and quality of life were younger in age and had better illness knowledge. Furthermore, physical function and independence in daily living significantly affected quality of life. Care for patients with heart failure, particularly older adults, should focus on teaching these patients about heart failure illness and symptom management. Assisting elderly patients with heart failure to promote and maintain physical functions to handle activities of daily living independently is critical to improving patient quality of life.

Does a wander garden influence inappropriate behaviors in dementia residents?

PubMed

Detweiler, Mark B; Murphy, Pamela F; Myers, Laura C; Kim, Kye Y

2008-01-01

The effect on resident behaviors of adding a wander garden to an existing dementia facility was investigated. 34 male residents were observed for 12 months before and after opening the garden. Behaviors were assessed using the Cohen-Mansfield Agitation Inventory Short Form (CMAI), incident reports, as needed medications (pro re nata [PRN]), and surveys of staff and residents' family members as indices of affect. Final CMAI scores and total PRNs employed were lower than baseline values with a trend for residents who used the garden more often to have less agitated behavior. Verbal inappropriate behaviors did not change significantly whereas physical incidents increased. Staff and family members felt that the wander garden decreased inappropriate behaviors and improved mood and quality of life of the dementia residents. Study design characteristics and garden management may have affected behaviors both positively and negatively. Additional studies are needed to explore the benefits of wander gardens for dementia residents.

The aim of the present study was to examine whether adolescents of Moroccan and Dutch origin differ concerning sibling relationship quality and to examine whether the associations between quality of the sibling relationship and level and change in externalizing and internalizing problem behavior are comparable for Moroccan and Dutch adolescents. Five annual waves of questionnaire data on sibling support and conflict as well as externalizing problems, anxiety and depression were collected from 159 ethnic Moroccan adolescents (Mage = 13.3 years) and from 159 ethnic Dutch adolescents (Mage = 13.0 years). Our findings demonstrated significant mean level differences between the Moroccan and Dutch sample in sibling relationship quality, externalizing problems, and depression, with Moroccan adolescents reporting higher sibling relationship quality and less problem behavior. However, effects of sibling relationship quality on externalizing problems, anxiety, and depression were similar for the Moroccan and Dutch samples. Sibling support was not related to level of externalizing problems, nor to changes in externalizing problems, anxiety, and depression. Additionally, more sibling conflict was related to a higher starting level of and faster decreases in problem behaviors. Our results support the ethnic equivalence model, which holds that the influence of family relationships is similar for different ethnic groups. Moreover, sibling support and conflict affect both the level and the fluctuations in problem behavior over time in specific ethnic groups similarly. Implications for future studies and interventions are subsequently discussed.

Song environment affects singing effort and vasotocin immunoreactivity in the forebrain of male Lincoln’s sparrows

Male songbirds often establish territories and attract mates by singing, and some song features can reflect the singer’s condition or quality. The quality of the song environment can change, so male songbirds should benefit from assessing the competitiveness of the song environment and appropriately adjusting their own singing behavior and the neural substrates by which song is controlled. In a wide range of taxa social modulation of behavior is partly mediated by the arginine vasopressin or vasotocin (AVP/AVT) systems. To examine the modulation of singing behavior in response to the quality of the song environment we compared the song output of laboratory-housed male Lincoln’s sparrows (Melospiza lincolnii) exposed to one week of chronic playback of songs categorized as either high or low quality, based on song length, complexity and trill performance. To explore the neural basis of any facultative shifts in behavior, we also quantified the subjects’ AVT immunoreactivity (AVT-IR) in three forebrain regions that regulate socio-sexual behavior: the medial bed nucleus of the stria terminalis (BSTm), the lateral septum (LS) and the preoptic area. We found that high quality songs increased singing effort and reduced AVT-IR in the BSTm and LS, relative to low quality songs. The effect of the quality of the song environment on both singing effort and forebrain AVT-IR raises the hypothesis that AVT within these brain regions plays a role in the modulation of behavior in response to competition that individual males may assess from the prevailing song environment.

2016-06-01

We investigated the potential stress-buffering effect of 3 health behaviors-physical activity, sleep quality, and snacking-on affect in the context of everyday life in young adults. In 2 intensive longitudinal studies with up to 65 assessment days over an entire academic year, students (Study 1, N = 292; Study 2, N = 304) reported stress intensity, sleep quality, physical activity, snacking, and positive and negative affect. Data were analyzed using multilevel regression analyses. Stress and positive affect were negatively associated; stress and negative affect were positively associated. The more physically active than usual a person was on a given day, the weaker the association between stress and positive affect (Study 1) and negative affect (Studies 1 and 2). The better than usual a person's sleep quality had been during the previous night, the weaker the association between stress and positive affect (Studies 1 and 2) and negative affect (Study 2). The association between daily stress and positive or negative affect did not differ as a function of daily snacking (Studies 1 and 2). On stressful days, increasing physical activity or ensuring high sleep quality may buffer adverse effects of stress on affect in young adults. These findings suggest potential targets for health-promotion and stress-prevention programs, which could help reduce the negative impact of stress in young adults.

Rosenstein, Alan H; O'Daniel, Michelle

2006-07-01

There is a growing concern about the role of human factor issues and their effect on patient safety and clinical outcomes of care. Problems with disruptive behaviors negatively affect communication flow and team dynamics, which can lead to adverse events and poor quality outcomes. A 25-question survey tool was used to assess the status and significance of disruptive behaviors around perioperative services in a large metropolitan academic medical center. Results were analyzed and compared with those from a national databank to identify areas of concern and opportunities for improvement. Disruptive behaviors were a common occurrence in the perioperative setting. These types of behaviors were most prevalent in attending surgeons. Disruptive behaviors increased levels of stress and frustration, which impaired concentration, impeded communication flow, and adversely affected staff relationships and team collaboration. These events were perceived to increase the likelihood of medical errors and adverse events and to compromise patient safety and quality of care. Disruptive behaviors in the perioperative arena have a significant impact on team dynamics and communication flow, which can have a negative impact on patient care. Organizations need to recognize the prevalence and significance of disruptive behaviors and develop policies and processes to address the issue. Key areas of focus include recognition and awareness, organizational and cultural commitment, implementation of appropriate codes of behavior policies and procedures, and provision of education and training programs to discuss contributing factors and tools to build effective communication and team collaboration skills.

Affiliation and control in marital interaction: interpersonal complementarity is present but is not associated with affect or relationship quality.

PubMed

Cundiff, Jenny M; Smith, Timothy W; Butner, Jonathan; Critchfield, Kenneth L; Nealey-Moore, Jill

2015-01-01

The principle of complementarity in interpersonal theory states that an actor's behavior tends to "pull, elicit, invite, or evoke" responses from interaction partners who are similar in affiliation (i.e., warmth vs. hostility) and opposite in control (i.e., dominance vs. submissiveness). Furthermore, complementary interactions are proposed to evoke less negative affect and promote greater relationship satisfaction. These predictions were examined in two studies of married couples. Results suggest that complementarity in affiliation describes a robust general pattern of marital interaction, but complementarity in control varies across contexts. Consistent with behavioral models of marital interaction, greater levels of affiliation and lower control by partners-not complementarity in affiliation or control-were associated with less anger and anxiety and greater relationship quality. Partners' levels of affiliation and control combined in ways other than complementarity-mostly additively, but sometimes synergistically-to predict negative affect and relationship satisfaction. © 2014 by the Society for Personality and Social Psychology, Inc.

Disruptive behavior can have a significant impact on care delivery, which can adversely affect patient safety and quality outcomes of care. Disruptive behavior occurs across all disciplines but is of particular concern when it involves physicians and nurses who have primary responsibility for patient care. There is a higher frequency of disruptive behavior in neurologists compared to most other nonsurgical specialties. Disruptive behavior causes stress, anxiety, frustration, and anger, which can impede communication and collaboration, which can result in avoidable medical errors, adverse events, and other compromises in quality care. Health care organizations need to be aware of the significance of disruptive behaviors and develop appropriate policies, standards, and procedures to effectively deal with this serious issue and reinforce appropriate standards of behavior. Having a better understanding of what contributes to, incites, or provokes disruptive behaviors will help organizations provide appropriate educational and training programs that can lessen the likelihood of occurrence and improve the overall effectiveness of communication among the health care team.

Although parenting behavior and friendship quality predict adolescent externalizing behaviors (EBs), individual differences in temperament may differentially affect susceptibility to these factors over time. In a multi-method and multi-informant study of 141 children followed prospectively from toddlerhood to adolescence, we tested the independent and interactive associations of age 3 reactive temperament (e.g., negative emotionality) and age 13 observed parenting (i.e., positive and negative behavior) and friendship (i.e., conflict and warmth), with multi-informant ratings of age 15 aggression and rule-breaking behavior. Negative parenting predicted growth in parent-rated EB, but only for adolescents with early reactive temperament. Temperament did not affect sensitivity to positive parenting or friendship. Results are discussed in the context of differential susceptibility theory and intervention implications for adolescents. © 2018 Society for Research on Adolescence.

This study was designed to identify variables affecting family functions and life quality of parents with cleft lip and/or palate children. Family Assesment Scale (FAS) and short form of World Health Organization quality of life (WHOQOL-BREF-TR) were used to measure family functions and life quality of parents. Questionnaire Forms were given to 146 parents: 74 having cleft lip and/or palate children (cleft-group), and the other 72 with healthy children (control-group). Parents were divided into 3 subgroups according to children's age as 0 to 6, 7 to 12, and 13 to 18 years. Kruskal-Wallis and Mann-Whitney U tests were used to evaluate differences between the groups. Behavior of cleft patients' parents was found to be problematic in behavioral control, required attention and role areas at 0 to 6 years, required attention area at ages 7 to 12 and 13 to 18 years. When compared to control group, significant differences were detected in required attention at ages 0 to 6 years, problem-solving, and communication areas at 7 to 12 years. Findings of life quality were found to be over medium level in physical, social, psychological and environmental areas in cleft group at all age groups; however, life quality was found better in control group in physical, psychological, and social subtests at age 13 to 18 years. Cleft children influence family functions in behavioral control, required attention and role areas at early childhood, and continue to affect required attention through adolescence. Also social, physical, and psychological fields of life quality were found lower in cleft parents compared to control group at adolescence.

Understanding a child's ability to decode emotion expressions is important to allow early interventions for potential difficulties in social and emotional functioning. This study applied the Rasch model to investigate the psychometric properties of the NEPSY-II Affect Recognition subtest, a U.S. normed measure for 3-16 year olds which assesses the ability to recognize facial expressions of emotion. Data were collected from 1222 children attending preschools in Singapore. We first performed the Rasch analysis with the raw item data, and examined the technical qualities and difficulty pattern of the studied items. We subsequently investigated the relation of the estimated affect recognition ability from the Rasch analysis to a teacher-reported measure of a child's behaviors, emotions, and relationships. Potential gender differences were also examined. The Rasch model fits our data well. Also, the NEPSY-II Affect Recognition subtest was found to have reasonable technical qualities, expected item difficulty pattern, and desired association with the external measure of children's behaviors, emotions, and relationships for both boys and girls. Overall, findings from this study suggest that the NEPSY-II Affect Recognition subtest is a promising measure of young children's affect recognition ability. Suggestions for future test improvement and research were discussed.

Parents’ Relationship Quality and Children’s Behavior in Stable Married and Cohabiting Families

Goldberg, Julia S.; Carlson, Marcia J.

2014-01-01

Although an extensive literature has shown that family structure is linked with child well-being, less well understood is how the dynamics within families affect children, in particular the extent to which positive mother–father relationship quality is linked with children’s outcomes. In this study the authors used data from the Fragile Families and Child Wellbeing Study (N = 773) to examine how couple supportiveness in stable coresident families is related to children’s externalizing and internalizing behavioral problems over ages 3 through 9. Using latent growth curve and fixed effects models, they found that parents’ greater supportiveness has a slight association with lower levels of children’s behavioral problems. Using cross-lagged structural equation models to examine the direction of the association, they also found some evidence that parents’ relationship quality and children’s behavioral problems are reciprocally related. Overall, this study suggests that more positive couple interactions are beneficial for children residing with both of their biological parents. PMID:25125703

The best friendships of aggressive boys: relationship quality, conflict management, and rule-breaking behavior.

Bagwell, Catherine L; Coie, John D

2004-05-01

The current study examined the best friendships of aggressive and nonaggressive boys (N = 96 boys, 48 dyads, mean age = 10.6 years). Friends completed self-report measures of friendship quality, and their interactions were observed in situations that required conflict management and provided opportunities for rule-breaking behavior. Although there were no differences in boys' self-reports of friendship quality, observers rated nonaggressive boys and their friends as showing greater positive engagement, on-task behavior, and reciprocity in their interactions compared with aggressive boys and their friends. Aggressive boys and their friends provided more enticement for rule violations and engaged in more rule-breaking behavior than did nonaggressive boys and their friends. Also, the intensity of negative affect in observed conflicts between aggressive boys and their friends was greater than that between nonaggressive boys and their friends. The findings suggest that friendships may provide different developmental contexts for aggressive and nonaggressive boys. Copyright 2003 Elsevier, Inc.

The interplay between sleep behavior and affect in elementary school children's daily life.

2016-10-01

Recent reviews raised the idea of a bidirectional relation between sleep behavior and affect in adults, but little is known about this interplay in general and especially regarding children. In this micro-longitudinal study, the interplay of sleep and affect was captured directly in children's daily life context in and out of school through ambulatory assessment. For 31 consecutive days, 110 elementary school children (8-11 years old) provided information about their last night's sleep and reported their current affect at four daily occasions in school and at home on smartphones. A multilevel approach was used to analyze the relation between sleep and affect the next day (morning, noon, and afternoon) and the relation between evening affect and subsequent sleep. At the within-person level, sleep quality was related to all observed facets of affect the next day and the strongest effects were found in the morning. The effect of sleep quality on positive affect was particularly pronounced for children who on average went to bed early and slept long. There were, however, no direct within-person effects of sleep quantity on affect. Furthermore, evening affect was related to subsequent sleep. The findings support the idea of a bidirectional relation between affect and sleep in children's daily life (including school). They suggest that good sleep provides a basis and resource for children's affective well-being the next day and demonstrate the importance of analyzing within-person variations of children's sleep. Micro-longitudinal findings can contribute to explain how macro-longitudinal relations between sleep and affect develop over time. Copyright © 2016 Elsevier Inc. All rights reserved.

Does knowledge of coronary artery calcium affect cardiovascular risk perception, likelihood of taking action, and health-promoting behavior change?

Evidence indicates that a healthy lifestyle can reduce cardiovascular disease risk, yet many people engage in unhealthy behaviors. New technologies such as coronary artery calcium (CAC) screening detect atherosclerosis before clinical disease is manifested. Knowledge of an abnormal finding could provide the "teachable moment" to enhance motivation for change. The aim of this study was to examine how knowledge of CAC score affects risk perception, likelihood of taking action, and health-promoting behavior change in persons at high risk for cardiovascular disease. This study used a descriptive prospective design with 174 high-risk adults (≥3 major risk factors) recruited at a radiology center offering CAC scans. Baseline self-report surveys using the Perception of Risk of Heart Disease Scale, the Benefits and Barriers Scale, the Quality of Life Index, and the Health-Promoting Lifestyle Profile II were completed immediately after a screening CAC scan but before results were known. Follow-up occurred 3 months later using mailed packets. Participants' mean age was 58 years; 62% were men, 89% were white, and most were well educated. There was no significant change in risk perception scores over time or between groups, except for a positive interaction in the moderate-risk group (CAC scores of 101-400) (P = .004). Quality of life remained unchanged. Health-promoting behavior changes increased in all groups over time (P < .001). McNemar χ² analysis indicated that risk reduction medication use increased in all groups, with a significant increase in statin (P < .001) and aspirin (P < .001) intake. Predictors of behavior change were perceived barriers (β = -.41; P < .001) and quality of life (β = .44; P < .001). Knowledge of CAC score does impact risk perception for some at-risk groups. This knowledge does enhance motivation for behavior change. Knowledge of CAC score does not impact quality of life. It is hoped that through improved understanding of the effect of CAC scoring on behavior change, nurses can better assist patients to modify behaviors during teachable moments.

Purpose The affective properties of infant-directed speech influence the attention of infants with normal hearing to speech sounds. This study explored the affective quality of maternal speech to infants with hearing impairment (HI) during the 1st year after cochlear implantation as compared to speech to infants with normal hearing. Method Mothers of infants with HI and mothers of infants with normal hearing matched by age (NH-AM) or hearing experience (NH-EM) were recorded playing with their infants during 3 sessions over a 12-month period. Speech samples of 25 s were low-pass filtered, leaving intonation but not speech information intact. Sixty adults rated the stimuli along 5 scales: positive/negative affect and intention to express affection, to encourage attention, to comfort/soothe, and to direct behavior. Results Low-pass filtered speech to HI and NH-EM groups was rated as more positive, affective, and comforting compared with the such speech to the NH-AM group. Speech to infants with HI and with NH-AM was rated as more directive than speech to the NH-EM group. Mothers decreased affective qualities in speech to all infants but increased directive qualities in speech to infants with NH-EM over time. Conclusions Mothers fine-tune communicative intent in speech to their infant's developmental stage. They adjust affective qualities to infants' hearing experience rather than to chronological age but adjust directive qualities of speech to the chronological age of their infants. PMID:25679195

Self-management and quality of life in chronic obstructive pulmonary disease (COPD): The mediating effects of positive affect.

Benzo, Roberto P; Abascal-Bolado, Beatriz; Dulohery, Megan M

2016-04-01

This study aimed to increase our understanding of general self-management (SM) abilities in COPD by determining if SM can predict disease specific quality of life (QoL), by investigating whether specific SM domains are significant in COPD and by exploring the mediating effect of the positive/negative affect in the association between SM and QoL. Cross-sectional study based on 292 patients with COPD. Measures included demographics, lung function, gait speed, health care utilization, positive/negative affect, SM abilities, breathlessness and disease specific QoL. We performed, correlation, multiple regression models and mediation analysis (positive/negative affect being mediator between SM and QoL association). After controlling for breathlessness, living alone, marital status, hospitalization history, age and lung function, SM related to QoL (p<0.0001). Investment in behaviors (hobbies and social relationships) and self-efficacy are SM domains independently related to QoL in COPD. Positivity measured by the positive/negative affect ratio completely mediates the relationship of SM with QoL. SM is independently associated with disease specific QoL in COPD after adjustment significant covariates but positive/negative affect ratio completely mediates the relationship of SM with QoL. Measuring positive/negative affect and addressing investment behavior and self-efficacy are important in implementing COPD-SM programs. Copyright © 2015 The Authors.

Objective: Systematic review of the literature pertaining to quality of life studies in adults suffering from insomnia, by specifically addressing the following questions: 1) What is the impact of insomnia on quality of life? 2) To what extent do comorbid conditions affect quality of life in patients with insomnia? 3) What is the impact of insomnia treatment on quality of life? Design: Our search was conducted using the MEDLINE/PubMed and PsycINFO databases from the past 25 years (1987–2012), using the keywords “Insomnia” AND “Quality of Life,” “QOL,” “Health-related quality of life,” or “HRQOL.” Fifty-eight studies were selected for inclusion by two physicians who reached a consensus about the studies to include in this review. Results: The literature reveals that quality of life is severely impaired in individuals with insomnia, comorbid conditions significantly affects quality of life negatively, and sleep restoration techniques, including cognitive behavioral therapy and medications, are successful at improving quality of life. However, restoration of quality of life to community levels is still unclear. Conclusion: Insomnia and its comorbidities negatively affect an individual’s quality of life, and different modalities of treatment can produce improvements in physical and psychological wellbeing and quality of life. More research is needed to develop more interventions that specifically focus on improving quality of life in patients suffering from insomnia. PMID:23198273

Cancer control research involves the conduct of basic and applied behavioral and social sciences to reduce cancer incidence, morbidity, and mortality, and improve quality of life. Given the importance of behavior in cancer control, fundamental research is necessary to identify psychological mechanisms underlying cancer risk, prevention, and management behaviors. Cancer prevention, diagnosis, and treatment are often emotionally-laden. As such, affective science research to elucidate questions related to basic phenomenological nature of emotion, stress, and mood is necessary to understand how cancer control can be hindered or facilitated by emotional experiences. To date, the intersection of basic affective science research and cancer control remains largely unexplored. The goal of this paper is to outline key questions in the cancer control research domain that provide an ecologically valid context for new affective science discoveries. We also provide examples of ways in which basic affective discoveries could inform future cancer prevention and control research. These examples are not meant to be exhaustive or prescriptive, but instead are offered to generate creative thought about the promise of a cancer research context for answering basic affective science questions. Together, these examples provide a compelling argument for fostering collaborations between affective and cancer control scientists. PMID:25987511

There is a great deal of variability in mother-infant interactions and infant behavior across the first year of life in rhesus monkeys. The current paper has two specific aims: 1) to determine if birth timing predicts variability in the mother-infant relationship and infant behavior during weaning and maternal breeding, and 2) to identify predictors of infant behavior during a period of acute challenge, maternal breeding. Forty-one mother-infant pairs were observed during weaning when infants were 4.5 months old, and 33 were followed through maternal breeding. Subjective ratings of 16 adjectives reflecting qualities of maternal attitude, mother-infant interactions, and infant attitude were factor analyzed to construct factors relating to the mother-infant relationship (Relaxed and Aggressive), and infant behavior (Positive Engagement and Distress). During weaning, late born infants were more Positively Engaged than peak born infants (ANOVA, P < 0.05); however, birth timing did not affect the mother-infant relationship factors Relaxed and Aggressive or the infant attitude factor Distress. During maternal breeding early born infants had less Relaxed relationships with their mothers than peak or late born infants, higher Positive Engagement scores than peak or late born infants, and tended to have higher Distress scores than peak born infants (Repeated-measures ANOVA, P < 0.05). In addition, Distress scores were higher during maternal breeding than during the pre- and post-breeding phases. Finally, multiple regression (P < 0.05) indicated that while infant behavioral responsiveness predicted infant Positive Engagement during the acute challenge of maternal breeding, qualities of the mother-infant relationship predicted infant Distress. These data suggest that birth timing influences the patterns of mother-infant interactions during weaning and maternal breeding. Additionally, infant behavioral responsiveness and mother-infant relationship quality impact infant social engagement and affect expression, respectively. PMID:24436198

Mother–Child Interactions in the NICU: Relevance and Implications for Later Parenting

2015-01-01

Objective This study examined the feasibility of observing mother–child interactions in the neonatal intensive care unit (NICU), whether NICU interactions related to later interactions, and how interactions related to child and maternal characteristics. Methods The sample included 130 preterm infants and their mothers, observed in a feeding interaction in the NICU. Dyads were observed through 36 months postterm. Results Observed maternal positive affective involvement and verbalizations in the NICU were associated with the same parenting behaviors at 24 months, social support, socioeconomic status, and being born in the late preterm period. Maternal negative affect and behavior were unrelated to later maternal negativity or child and maternal characteristics. Conclusions Positive parenting assessed in the NICU appears related to later parenting interaction quality, suggesting early assessment is possible. Maternal negative affect and behavior toward children may not consistently emerge until later in development. PMID:25113147

The rapid advancement of Internet and computer technology has not only influenced the way we live, but also the way we learn. Due to the implementation of e-learning in urban junior high schools in Taiwan, it has become essential to find out how external and internal factors affect junior high school students' online learning behavior, which consequently affects their learning outcome. The present study aims to propose a conceptual structural equation model to investigate the relationships among e-Learning system quality (eLSQ), technology readiness (TR), learning behavior (LB), and learning outcome (LO), and to demonstrate the direct and indirect effect of eLSQ and TR on LO from the perspectives of LB. Data collected from 10 urban junior high schools in Taiwan (N = 376) were analyzed using structural equation modeling. Results reveal that both eLSQ and TR have a direct and significant impact on LB. However, eLSQ and TR influence LO indirectly through LB. In addition, LB has a direct and positive significant influence on LO. Managerial implications are proposed and research limitations are discussed.

Background Snacking behaviors have been linked with higher energy intake and excess weight. However results have been inconsistent. Moreover, few data are available on the extent to which snacking affects diet quality. Objective This study describes snacking behaviors, including total snacking energy, frequency, time of day, and percentage of snacking energy intake by food groups, and their associations with diet quality and BMI. Design Snacking behaviors and dietary intake were examined cross-sectionally among 233 adults participating in a community-based worksite nutrition intervention from September 2010–February 2013. Three telephone-administered 24-hour dietary recalls were collected (two weekday; one weekend day). Diet quality was characterized by the Healthy Eating Index (HEI)-2010 and BMI was computed using measured height and weight. Setting The setting was a large metropolitan medical complex in Minneapolis, Minnesota. Main outcome measures Outcome measures included diet quality and BMI. Statistical analyses General linear regression models were used to examine associations between each of the snacking behaviors as independent variables, and diet quality and BMI as dependent variables. Results Percent of snacking energy from fruit & juice (β=0.13, P=0.001) and nuts (β=0.16, P=0.008) were significantly positively associated with diet quality. Percent of snacking energy from desserts and sweets (β=−0.16, P<0.001) and sugar-sweetened beverages (β=−0.22, P=0.024) were significantly inversely associated. Percent of snacking energy from vegetables (β=−0.18, P=0.044) was significantly associated with lower BMI. Percent snacking energy from desserts and sweets was significantly associated with a higher BMI (β=0.04, P=0.017). Conclusions Snack food choices, but not total energy from snacks, frequency or time of day, were significantly associated with diet quality and BMI. PMID:25769747

Song is a sexually selected trait that is thought to be an honest signal of the health condition of an individual in many bird species. For species that breed opportunistically, the quantity of food may be a determinant of singing activity. However, it is not yet known whether the quality of food plays an important role in this respect. The aim of the present study was to experimentally investigate the role of two calorie-free nutrients (lutein and cholesterol) in determining the expression of a sexually selected behavior (song rate) and other behaviors (locomotor activity, self-maintenance activity, eating and resting) in male zebra finches (Taeniopygia guttata). We predicted that males supplemented with lutein and cholesterol would sing at higher rates than controls because both lutein and cholesterol have important health-related physiological functions in birds and birdsong mirrors individual condition. To control for testosterone secretion that may upregulate birdsong, birds were exposed to a decreasing photoperiod. Our results showed that control males down-regulated testosterone in response to a decreasing photoperiod, while birds treated with lutein or cholesterol maintained a constant singing activity. Both lutein- and cholesterol-supplemented groups sang more than control groups by the end of the experiment, indicating that the quality of food can affect undirected song irrespective of circulating testosterone concentrations. None of the other measured behaviors were affected by the treatment, suggesting that, when individuals have full availability of food, sexually selected song traits are more sensitive to the effect of food quality than other behavioral traits. Overall the results support our prediction that undirected song produced by male zebra finches signals access to high-quality food. PMID:27761321

Parental emotional distress, particularly high maternal anxiety, is one of the most consistent predictors of child anxiety treatment outcome. In order to identify the cognitive, affective, and behavioral parenting characteristics of mothers of children with anxiety disorders who themselves have an anxiety disorder, we assessed the expectations, appraisals, and behaviors of 88 mothers of anxious children (44 mothers who were not anxious [NONANX] and 44 mothers with a current anxiety disorder [ANX]) when interacting with their 7-12-year-old children. There were no observed differences in anxiety and avoidance among children of ANX and NONANX mothers, but, compared with NONANX mothers, ANX mothers held more negative expectations, and they differed on observations of intrusiveness, expressed anxiety, warmth, and the quality of the relationship. Associations were moderated by the degree to which children expressed anxiety during the tasks. Maternal-reported negative emotions during the task significantly mediated the association between maternal anxiety status and the observed quality of the relationship. These findings suggest that maternal anxiety disorder is associated with reduced tolerance of children's negative emotions. This may interfere with the maintenance of a positive, supportive mother-child interaction under conditions of stress and, as such, this may impede optimum treatment outcomes. The findings identify potential cognitive, affective, and behavioral targets to improve treatment outcomes for children with anxiety disorders in the context of a current maternal anxiety disorder. 2013 APA, all rights reserved

Nursing Home Price and Quality Responses to Publicly Reported Quality Information

Objective To assess whether the release of Nursing Home Compare (NHC) data affected self-pay per diem prices and quality of care. Data Sources Primary data sources are the Annual Survey of Wisconsin Nursing Homes for 2001–2003, Online Survey and Certification Reporting System, NHC, and Area Resource File. Study Design We estimated fixed effects models with robust standard errors of per diem self-pay charge and quality before and after NHC. Principal Findings After NHC, low-quality nursing homes raised their prices by a small but significant amount and decreased their use of restraints but did not reduce pressure sores. Mid-level and high-quality nursing homes did not significantly increase self-pay prices after NHC nor consistently change quality. Conclusions Our findings suggest that the release of quality information affected nursing home behavior, especially pricing and quality decisions among low-quality facilities. Policy makers should continue to monitor quality and prices for self-pay residents and scrutinize low-quality homes over time to see whether they are on a pathway to improve quality. In addition, policy makers should not expect public reporting to result in quick fixes to nursing home quality problems. PMID:22092366

Interacting coastal based ecosystem services: recreation and water quality in Puget Sound, WA

Coastal recreation and water quality are major contributors to human well-being in coastal regions. They can also interact, creating opportunities for ecosystem based management, ecological restoration, and water quality improvement that can positively affect people and the environment. Yet the effect of environmental quality on human behavior is often poorly quantified, but commonly assumed in coastal ecosystem service studies. To clarify this effect we investigate a water quality dataset for evidence that environmental condition partially explains variation in recreational visitation, our indicator of human behavior. In Puget Sound, WA, we investigate variation in visitation in both visitation rate and fixed effects (FE) models. The visitation rate model relates the differences in annual recreational visitation among parks to environmental conditions, park characteristics, travel cost, and recreational demand. In our FE model we control for all time-invariant unobserved variables and compare monthly variation at the park level to determine how water quality affects visitation during the summer season. The results of our first model illustrate how visitation relates to various amenities and costs. In the FE analysis, monthly visitation was negatively related to water quality while controlling for monthly visitation trends. This indicates people are responding to changes in water quality, and an improvement would yield an increase in the value of recreation. Together, these results could help in prioritizing water quality improvements, could assist the creation of new parks or the modification of existing recreational infrastructure, and provide quantitative estimates for the expected benefits from potential changes in recreational visitation and water quality improvements. Our results also provide an example of how recreational visitation can be quantified and used in ecosystem service assessments.

To examine the health-related quality of life among workers in 22 standard occupation groups using data from the 2013-2014 US Behavioral Risk Factor Surveillance System. We examined the health-related quality of life measures of self-rated health, frequent physical distress, frequent mental distress, frequent activity limitation, and frequent overall unhealthy days by occupation group for 155 839 currently employed adults among 17 states. We performed multiple logistic regression analyses that accounted for the Behavioral Risk Factor Surveillance System's complex survey design to obtain prevalence estimates adjusted for potential confounders. Among all occupation groups, the arts, design, entertainment, sports, and media occupation group reported the highest adjusted prevalence of frequent physical distress, frequent mental distress, frequent activity limitation, and frequent overall unhealthy days. The personal care and service occupation group had the highest adjusted prevalence for fair or poor self-rated health. Workers' jobs affect their health-related quality of life.

The authors studied the health-related quality of life of children aged 5 to 18 years with Charcot-Marie-Tooth disease of varying types and severity and compared it with the general pediatric population. To capture and compare the quality-of-life data across a broad range of ages, the Child Health Questionnaire was completed by parents of 127 children with Charcot-Marie-Tooth disease. Affected children exhibited lower physical, psychological, and social well-being than the general pediatric population, with subsequent worsening of many domains with age. The type of Charcot-Marie-Tooth disease influenced some physical and behavioral quality-of-life domains, while gender, body size, and ethnicity did not. Parent characteristics had generally little impact on the reporting of their child's quality of life, although parents with Charcot-Marie-Tooth disease reported higher bodily pain in their children than those without. Overall, quality of life is negatively affected by the presence and severity of Charcot-Marie-Tooth disease in childhood.

Behavioral factors affecting exposure potential for household cleaning products.

Behavioral experiments were performed on 342 subjects to determine whether behavior, which could affect the level of personal exposure, is exhibited in response to odors and labels which are commonly used for household chemicals. Potential for exposure was assessed by having subjects perform cleaning tasks presented as a product preference test, and noting the amount of cleaning product used, the time taken to complete the cleaning task, the product preference, and the exhibition of avoidance behavior. Product odor was found to affect product preference in the study with the pleasant odored product being preferred to the neutral and unpleasant products. Product odor was also found to influence the amount of product used; less of the odored products was used compared to the neutral product. The experiment also found that very few of the subjects in the study read the product labels, precluding analysis of the effect of such labels on product use. A postexperiment questionnaire on household cleaning product purchasing and use was administered to participants. The results indicate that significant gender differences exist. Women in the sample reported more frequent purchase and use of cleaning products resulting in an estimated potential exposure 40% greater than for the men in the sample. This finding is somewhat countered by the fact that women more frequently reported exposure avoidance behavior, such as using gloves. Additional significant gender differences were found in the stated importance of product qualities, such as odor and environmental quality. This study suggests the need for further research, in a more realistic use setting, on the impact of public education, labels, and product odor on preference, use, and exposure for different types of consumer products.

Providing quality maternity care within the emergency care packages for internally displaced populations in war-affected areas is somewhat challenging, although very essential. In this retrospective study, we describe the experiences and health care seeking behaviors of 1,015 pregnant and postpartum women during the 2006 war in Lebanon. Women reported interruptions in regular maternity care and experienced more complications during this period. Availability of health services and experiences of complications were the most important determinants of health care seeking behaviors. Maternal health services should be a part of any comprehensive emergency responsiveness plan, catering to women's needs in war-affected areas.

The evolution of behavioral health care financing and delivery has led to a wide variety of arrangements connecting consumers to behavioral health services. In this paper, we present a typology based on three distinguishing features of behavioral health arrangements along which there is a high degree of variability and this variability has been shown to affect the cost and quality of behavioral health care: (1) the extent to which sponsor oversight over care is outsourced by way of contracts rather than performed directly; (2) whether financing for behavioral health is partitioned from health care financing overall; and (3) the amount of financial risk shared by the sponsor with third parties.

The effect of thermal quality on the thermoregulatory behavior of the bearded dragon Pogona vitticeps: influences of methodological assessment.

PubMed

Cadena, Viviana; Tattersall, Glenn J

2009-01-01

Metabolic functions are generally optimized within a narrow range of body temperatures (T(b)'s), conferring thermoregulation great importance to the survival and fitness of an animal. In lizards, T(b) regulation is mainly behavioral, and the metabolic costs associated with behavioral thermoregulation are primarily locomotory. In reptiles, however, it has been proposed that they thermoregulate less precisely when the associated costs, metabolic or otherwise, are high. Such a strategy enhances fitness by allowing lizards to be more flexible to changing environmental conditions while maximizing the benefits of maintaining a high T(b) and minimizing energy expenditure. We evaluated the behavioral thermoregulation of inland bearded dragons Pogona vitticeps under various thermal quality conditions requiring different locomotory investment for thermoregulation. The selected ambient temperature and preferred T(b) ranges increased at lower environmental thermal qualities, indicating a decrease in thermoregulatory precision in environments where the costs associated with thermoregulation were high. The level of thermoregulation was also affected, exhibiting a decrease in preferred T(b) of approximately 2 degrees C at the lowest-thermal-quality treatment. These data provide important implications for the procedural assessment of preferred T(b) and a better understanding of thermal set points in reptiles in general. Our results emphasize that the precise maintenance and assessment of preferred T(b) is contingent on the quality of the environment, laboratory or natural, that the animal inhabits.

The Affordable Care Act of 2010 launch of Medicare Value-Based Purchasing has become the platform for payment reform. It is a mechanism by which buyers of health care services hold providers accountable for high-quality and cost-effective care. The objective of the study was to examine the relationship between quality of hospital care and hospital competition using the quality-quantity behavioral model of hospital behavior. The quality-quantity behavioral model of hospital behavior was used as the conceptual framework for this study. Data from the American Hospital Association database, the Hospital Compare database, and the Area Health Resources Files database were used. Multivariate regression analysis was used to examine the effect of hospital competition on patient mortality. Hospital market competition was significantly and negatively related to the 3 mortality rates. Consistent with the literature, hospitals located in more competitive markets had lower mortality rates for patients with acute myocardial infarction, heart failure, and pneumonia. The results suggest that hospitals may be more readily to compete on quality of care and patient outcomes. The findings are important because policies that seek to control and negatively influence a competitive hospital environment, such as Certificate of Need legislation, may negatively affect patient mortality rates. Therefore, policymakers should encourage the development of policies that facilitate a more competitive and transparent health care marketplace to potentially and significantly improve patient mortality.

Prenatal Stress as a Risk-and an Opportunity-Factor.

PubMed

Hartman, Sarah; Freeman, Sara M; Bales, Karen L; Belsky, Jay

2018-04-01

Two separate lines of research indicate (a) that prenatal stress is associated with heightened behavioral and physiological reactivity and (b) that these postnatal phenotypes are associated with increased susceptibility to both positive and negative developmental experiences. Therefore, prenatal stress may increase sensitivity to the rearing environment. We tested this hypothesis by manipulating prenatal stress and rearing-environment quality, using a cross-fostering paradigm, in prairie voles. Results showed that prenatally stressed voles, as adults, displayed the highest behavioral and physiological reactivity when cross-fostered to low-contact (i.e., low-quality) rearing but the lowest behavioral and physiological reactivity when cross-fostered to high-contact (i.e., high-quality) rearing; non-prenatally stressed voles showed no effect of rearing condition. Additionally, while neither prenatal stress nor rearing condition affected oxytocin receptor binding, prenatally stressed voles cross-fostered to high-contact rearing showed the highest vasopressin-1a receptor binding in the amygdala. Results indicate that prenatal stress induces greater environmental sensitivity, making it both a risk and an opportunity factor.

2012-09-01

This study aims to explore the relationship between team-leadership skills and quality of cardiopulmonary resuscitation in an adult cardiac-arrest simulation. Factors affecting team-leadership skills were also assessed. Forty advanced life-support providers leading a cardiac arrest team in a standardized cardiac-arrest simulation were videotaped. Background data were collected, including age (in yrs), sex, whether they had received any leadership training in the past, whether they were part of a professional group, the most recent advanced life-support course (in months) they had undergone, advanced life-support instructor/provider status, and whether they had led in any cardiac arrest situation in the preceding 6 months. Participants were scored using the Cardiac Arrest Simulation test score and Leadership Behavior Description Questionnaire for leadership skills. Process-focused quality of cardiopulmonary resuscitation data were collected directly from manikin and video recordings. Primary outcomes were complex technical skills (measured as Cardiac Arrest Simulation test score, preshock pause, and hands-off ratio). Secondary outcomes were simple technical skills (chest-compression rate, depth, and ventilation rate). Univariate linear regressions were performed to examine how leadership skills affect quality of cardiopulmonary resuscitation and bivariate correlations elicited factors affecting team-leadership skills.Teams led by leaders with the best leadership skills performed higher quality cardiopulmonary resuscitation with better technical performance (R = 0.75, p < .001), shorter preshock pauses (R = 0.18, p < .001), with lower total hands-off ratio (R = 0.24, p = .01), and shorter time to first shock (R = 0.14, p = .02). Leadership skills were not significantly associated with more simple technical skills such as chest-compression rate, depth, and ventilation rate. Prior training in team leader skills was independently associated with better leadership behavior. There is an association between team leadership skills and cardiac arrest simulation test score, preshock pause, and hands off ratio. Developing leadership skills should be considered an integral part of resuscitation training.

Effects of Parental Stress, Optimism, and Health-Promoting Behaviors on the Quality of Life of Primiparous and Multiparous Mothers.

PubMed

Loh, Jennifer; Harms, Craig; Harman, Bronwyn

Parental stress, optimism, and health-promoting behaviors (HPBs) are important predictors of the quality of life (QoL) of mothers. However, it is unclear how strongly these predictors affect the QoL of mothers. It is also unclear if the impact of these predictors on QoL differs between primiparous and multiparous mothers. In this study, we defined primiparous as "bearing young for the first time" and multiparous as "having experienced one or more previous childbirths." The first objective of this study was to examine the relative effect of parental stress, optimism, and HPBs on the QoL of mothers. The second objective was to investigate if the effect of these predictors differed between primiparous and multiparous mothers. One hundred ninety-four Australian mothers (n = 87, 44.8% primiparous mothers) participated in an online survey that included the Parental Stress Scale, the Health-Promoting Lifestyle Profile II, the Revised Life Orientation Test, and the Quality of Life Enjoyment and Satisfaction Questionnaire. All predictors (parental stress, optimism, and HPBs) significantly affected the QoL of mothers; higher levels of optimism, greater use of HPBs, and lower parental stress were associated with higher levels of QoL for all mothers. Parity did not affect the relationships. This study sheds light on the nature and unique effect of parental stress, optimism, and HPBs on the QoL of mothers.

The authors examined the relationships between perceived organizational support, organizational commitment, commitment to customers, and service quality in a fast-food firm. The research design matched customer responses with individual employees' attitudes, making this study a true test of the service provider-customer encounter. On the basis of a sample of matched employee-customer data (N = 133), hierarchical linear modeling analyses revealed that perceived organizational support had both a unit-level and an employee-level effect on 1 dimension of service quality: helping behavior. Contrary to affective organizational commitment, affective commitment to customers enhanced service quality. The 2 sub-dimensions of continuance commitment to the organization--perceived high sacrifice and perceived lack of alternatives--exerted effects opposite in sign: The former fostered service quality, whereas the latter reduced it. The implications of these findings are discussed within the context of research on employee-customer encounters.

Earlier research suggests that the natural verbal discourse of mothers with their children can be important in clarifying, verifying, and evaluating the behavior in which a child is engaged, in attributing qualities to the child, and in influencing the child's self-perceptions. We investigated the potential influences of parental affective illness (bipolar affective disorder and unipolar depression in contrast to no history of psychiatric illness) on such "labeling" behavior in a sample of 61 mothers and their older (school-age) and younger (preschool-age) children. It was hypothesized that the dispositions characterizing affective illness (specifically, negativity and disengagement) would be reflected in the labeling statements of mothers with a diagnosis as they interacted with their children. Based on videotaped interactions during a visit to a home-like laboratory apartment, labeling statements were identified in terms of speaker and person being labeled ("addressee") and coded (positive, negative, mixed, or neutral) for judgmental and affective quality of the statement and reaction of the addressee. Data were analyzed (a) by family unit and (b) my mother to child statements. The general pattern of findings indicated, in relative terms, an excess of negativity on the part of family members in the bipolar group and a dearth of negative affect for mothers in the unipolar group. Negativity in the bipolar group appeared to be especially likely when the setting involved mothers and two male children. Additionally, findings are discussed in terms of sex differences in vulnerability to depression.

Feeling Thanks and Saying Thanks: A Randomized Controlled Trial Examining If and How Socially Oriented Gratitude Journals Work.

This study examined the effect of a reflective interpersonal gratitude journal, a reflective-behavioral interpersonal gratitude journal and an active control journal, on primary qualities of well-being and depression. Participants (n = 192; 67.2% female) completed this 3-month longitudinal randomized controlled design. Participants in the reflective-behavioral condition experienced the greatest improvements in affect balance and reductions in depression at immediate posttest. Both gratitude interventions improved affect balance at 1 month, compared to the control. Changes in affect balance for those in the reflective-behavioral condition were mediated by the rate at which people expressed gratitude in their existing relationships. This effect was moderated by participant's baseline depressive status. Expressing felt gratitude to others appears to be a crucial step in deriving benefits, and these benefits may not be limited to the emotionally healthy. Given the applied popularity of gratitude interventions, understanding not only if but also how they work is essential. © 2017 Wiley Periodicals, Inc.

2013-01-01

A mixed-method study identified profiles of fathers who mentioned key dimensions of their parenting and linked profile membership to adolescents’ adjustment using data from 337 European American, Mexican American and Mexican immigrant fathers and their early adolescent children. Father narratives about what fathers do well as parents were thematically coded for the presence of five fathering dimensions: emotional quality (how well father and child get along), involvement (amount of time spent together), provisioning (the amount of resources provided), discipline (the amount and success in parental control), and role modeling (teaching life lessons through example). Next, latent class analysis was used to identify three patterns of the likelihood of mentioning certain fathering dimensions: an emotionally-involved group mentioned emotional quality and involvement; an affective-control group mentioned emotional quality, involvement, discipline and role modeling; and an affective-model group mentioned emotional quality and role modeling. Profiles were significantly associated with subsequent adolescents’ reports of adjustment such that adolescents of affective-control fathers reported significantly more externalizing behaviors than adolescents of emotionally-involved fathers.

Employed parents’ work and family conditions provide behavioral contexts for their food choices. Relationships between employed parents’ food-choice coping strategies, behavioral contexts, and dietary quality were evaluated. Data on work and family conditions, sociodemographic characteristics, eating behavior, and dietary intake from two 24-hour dietary recalls were collected in a random sample cross-sectional pilot telephone survey in the fall of 2006. Black, white, and Latino employed mothers (n=25) and fathers (n=25) were recruited from a low/moderate income urban area in upstate New York. Hierarchical cluster analysis (Ward’s method) identified three clusters of parents differing in use of food-choice coping strategies (ie, Individualized Eating, Missing Meals, and Home Cooking). Cluster sociodemographic, work, and family characteristics were compared using χ2 and Fisher’s exact tests. Cluster differences in dietary quality (Healthy Eating Index 2005) were analyzed using analysis of variance. Clusters differed significantly (P≤0.05) on food-choice coping strategies, dietary quality, and behavioral contexts (ie, work schedule, marital status, partner’s employment, and number of children). Individualized Eating and Missing Meals clusters were characterized by nonstandard work hours, having a working partner, single parenthood and with family meals away from home, grabbing quick food instead of a meal, using convenience entrées at home, and missing meals or individualized eating. The Home Cooking cluster included considerably more married fathers with nonemployed spouses and more home-cooked family meals. Food-choice coping strategies affecting dietary quality reflect parents’ work and family conditions. Nutritional guidance and family policy needs to consider these important behavioral contexts for family nutrition and health. PMID:21338739

Perceived health in lung cancer patients: the role of positive and negative affect.

PubMed

Hirsch, Jameson K; Floyd, Andrea R; Duberstein, Paul R

2012-03-01

To examine the association of affective experience and health-related quality of life in lung cancer patients, we hypothesized that negative affect would be positively, and positive affect would be negatively, associated with perceived health. A sample of 133 English-speaking lung cancer patients (33% female; mean age = 63.68 years old, SD = 9.37) completed a battery of self-report surveys. Results of our secondary analysis indicate that trait negative affect was significantly associated with poor physical and social functioning, greater role limitations due to emotional problems, greater bodily pain, and poor general health. Positive affect was significantly associated with adaptive social functioning, fewer emotion-based role limitations, and less severe bodily pain. In a full model, positive affect was significantly associated with greater levels of social functioning and general health, over and above the effects of negative affect. Reduction of negative affect is an important therapeutic goal, but the ability to maintain positive affect may result in greater perceived health. Indeed, engagement in behaviors that result in greater state positive affect may, over time, result in dispositional changes and enhancement of quality of life.

Influence of water flow on Neosho madtom (Noturus placidus) reproductive behavior

2006-01-01

The Neosho madtom is a small, short-lived catfish species endemic to gravel bars of the Neosho River in Kansas, Oklahoma and Missouri, U.S.A. It spawns during summer in nesting cavities excavated in gravel. Although the species has survived dam construction within the Neosho River basin, its declining numbers resulted in it being added to the federal threatened species list in 1991. To test how water flow affects the reproductive behavior of Neosho madtoms, we compared activities of male-female pairs in static versus flowing-water aquaria. Using a behavioral catalog, we recorded their behavior sequences during randomly selected 5-min nighttime periods. For males and females, Jostle and Embrace were the most performed reproductive behaviors and the Jostle-Embrace-Carousel was the most performed reproductive behavior sequence. Water flow decreased the mean frequency of occurrence, percentage of time spent and mean event duration of male Nest Building. Because Neosho madtom courtship, reproduction and parental care is a complex and extended process, disturbances such as heightened river flows during the species' spawning season may negatively affect nest quality and reproductive success.

Physical pain and negative affect have been described as risk factors for alcohol use following alcohol treatment. The current study was a secondary analysis of 2 clinical trials for alcohol use disorder (AUD) to examine the associations between pain, negative affect and AUD treatment outcomes. Participants included 1,383 individuals from the COMBINE Study (COMBINE Pharmacotherapies and Behavioral Interventions for Alcohol Dependence; COMBINE Study Research Group, 2003; 31% female, 23% ethnic minorities, average age = 44.4 [SD = 10.2]), a multisite combination pharmacotherapy and behavioral intervention study for AUD in the United States, and 742 individuals from the United Kingdom Alcohol Treatment Trial (UKATT Research Team, 2001; 25.9% female, 4.4% ethnic minorities, average age = 41.6 [SD = 10.1]) a multisite behavioral intervention study for AUD in the United Kingdom. The Form-90 was used to collect alcohol use data, the Short Form Health Survey and Quality of Life measures were used to assess pain, and negative affect was assessed using the Brief Symptom Inventory (COMBINE) and the General Health Questionnaire (UKATT). Pain scores were significantly associated with drinking outcomes in both datasets. Greater pain scores were associated with greater negative affect and increases in pain were associated with increases in negative affect. Negative affect significantly mediated the association between pain and drinking outcomes and this effect was moderated by social behavior network therapy (SBNT) in the UKATT study, with SBNT attenuating the association between pain and drinking. Findings suggest pain and negative affect are associated among individuals in AUD treatment and that negative affect mediated pain may be a risk factor for alcohol relapse.

Putrajaya is a new federal administrative capital of Malaysia which has been set to achieve a 70% share of all travels by public transport in the city area. However, the current modal split between the public transport and private transport is 15 : 85. In order to understand travelers' willingness to use the public transport, a conceptual model has been developed to determine the factors that affect them to use the public transport instead of travelling in their own cars. Various variables such as service quality, environmental impact, attitude, and behavior intention were analyzed and tested using structural equation model (SEM). Results indicate that the service quality and attitude are found to have positive effects on the behavioral intention of taking the public transport. Other than this, this study also shows that the service quality and environmental impact have some positive influences on the attitude to using the public transport. However, environmental impact has no significant, positive, and direct effect on behavioral intention. The results of this study demonstrate that the model that was developed is useful in predicting the public transport and it could provide a more complete understanding of behavioral intention towards public transport use.

As well as being a very common neurological disease worldwide, epilepsy significantly impairs patients' emotional, behavioral, and cognitive functioning. Sleep disturbances are the most frequent complaint in patients with epilepsy. The present study assesses the impact of a range of affective symptoms on subjective sleep quality and sleep disturbances in Chinese adults with epilepsy. Adults with epilepsy who visited our epilepsy clinic from July 2015 to March 2016 were enrolled in our study. Both patients and healthy controls completed the Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), Insomnia Severity Index (ISI), Beck Depression Inventory-II (BDI-II), Beck Anxiety Inventory (BAI), and Mini-mental State Examination (MMSE). Subjective sleep quality and sleep disturbances were examined with regard to self-reported symptoms of depression and anxiety, seizure-related factors, and demographic factors. The PSQI scores and ISI scores of patients were significantly higher (indicating lower quality sleep and more serious insomnia) than those of the control group. Symptoms associated with depression and anxiety were independently related to impaired subjective sleep quality and insomnia. Affective symptoms explained more of the variance in PSQI scores and ISI scores than did seizure-related or demographic variables. In addition, these variables also seemed to be less powerful contributing factors to subjective sleep quality and insomnia than affective symptoms, several seizure-related factors, such as seizure control, partial seizures and duration of epilepsy, which are also significantly associated with subjective sleep quality and insomnia. In addition, use of lamotrigine (LTG) was also associated with insomnia and use of clonazepam (CZP) and phenobarbital (PB) with daytime sleepiness in patients with epilepsy. Chinese adults with epilepsy have poorer self-reported subjective sleep quality and a higher prevalence of insomnia than the control group. Depressive- and anxiety-related symptoms independently exert an adverse effect on the subjective sleep quality and insomnia of patients. In addition, seizure control, partial seizures, and the duration of epilepsy affect the quality of sleep and insomnia in patients, but seem less powerful predictors of sleep quality and insomnia than affective symptoms. Early identification and treatment of affective symptoms is of great importance in improving the sleep quality and insomnia of patients with epilepsy. Copyright © 2017 Elsevier B.V.

The diffusion decision model: theory and data for two-choice decision tasks.

Ratcliff, Roger; McKoon, Gail

2008-04-01

The diffusion decision model allows detailed explanations of behavior in two-choice discrimination tasks. In this article, the model is reviewed to show how it translates behavioral data-accuracy, mean response times, and response time distributions-into components of cognitive processing. Three experiments are used to illustrate experimental manipulations of three components: stimulus difficulty affects the quality of information on which a decision is based; instructions emphasizing either speed or accuracy affect the criterial amounts of information that a subject requires before initiating a response; and the relative proportions of the two stimuli affect biases in drift rate and starting point. The experiments also illustrate the strong constraints that ensure the model is empirically testable and potentially falsifiable. The broad range of applications of the model is also reviewed, including research in the domains of aging and neurophysiology.

Background There is persistent public concern about sleep disturbances due to radiofrequency electromagnetic field (RF-EMF) exposure. The aim of this prospective cohort study was to investigate whether sleep quality is affected by mobile phone use or by other RF-EMF sources in the everyday environment. Methods We conducted a prospective cohort study with 955 study participants aged between 30 and 60 years. Sleep quality and daytime sleepiness was assessed by means of standardized questionnaires in May 2008 (baseline) and May 2009 (follow-up). We also asked about mobile and cordless phone use and asked study participants for consent to obtain their mobile phone connection data from the mobile phone operators. Exposure to environmental RF-EMF was computed for each study participant using a previously developed and validated prediction model. In a nested sample of 119 study participants, RF-EMF exposure was measured in the bedroom and data on sleep behavior was collected by means of actigraphy during two weeks. Data were analyzed using multivariable regression models adjusted for relevant confounders. Results In the longitudinal analyses neither operator-recorded nor self-reported mobile phone use was associated with sleep disturbances or daytime sleepiness. Also, exposure to environmental RF-EMF did not affect self-reported sleep quality. The results from the longitudinal analyses were confirmed in the nested sleep study with objectively recorded exposure and measured sleep behavior data. Conclusions We did not find evidence for adverse effects on sleep quality from RF-EMF exposure in our everyday environment. PMID:22624036

Self-concepts of exercise in frail older adults with heart failure: a literature review.

2015-01-01

The co-occurrence of frailty and heart failure (HF) in older adults (65 years or older) can adversely affect the ability to engage in self-care management behaviors, which may alter self-concepts and decrease quality of life. Little is known about how frailty and HF influence older adults' self-concepts or how these self-concepts affect exercise behaviors. Therefore, the aims of this literature review were to identify the self-concepts of older frail adults with HF and to identify how these self-concepts affect their exercise behaviors. Guided by the schema model of self-concept, publications before April 2013 that examined the impact of the self-concepts of older adults with HF and/or frailty on exercise behavior were reviewed. As a result, 6 articles were included. Three of the 6 articles focused on frailty, and 3 of the 6 articles focused on HF. However, no study was found that specifically examined the self-concepts of frail older adults with HF. The self-concepts of older adults with HF and/or frailty are multifaceted and include both cognitive resources (facilitating exercise) and cognitive liabilities (hindering exercise). Studies are needed to determine how the co-occurrence of frailty and HF impact self-concepts and exercise behaviors in older adults.

There have been no systematic reviews that investigated the heritability of the two-factor model of psychopathy: interpersonal-affective and behavioral. Our review aimed, first, to examine the heritability of general psychopathic traits and, second, if genetic influences were suggested, to determine the heritability of various traits related to the interpersonal-affective and behavioral factors of psychopathy. A systematic literature search was conducted using articles from the PsycINFO, Embase, Global Health, Medline, PubMed, Web of Science, and Scopus databases (January of 1980 to December of 2015) in order to identify eligible literature that reported on the heritability of psychopathy-related traits. Papers were also found via manual examination and reference tracking. Papers were subjected to exclusion criteria and quality appraisal. We identified a total of 24 studies. Our results were grouped into three categories: general, interpersonal-affective, and behavioral. All these areas demonstrated modest to high heritability. The highest heritability values were found in studies investigating callous-unemotional behaviors. Heritability was found for all the psychopathic traits. Future research should include endophenotypic approaches that explore gene-environment correlations, which could aid in identification of the behavioral phenotype that is most amenable to early intervention by way of moderation of genetic risk.

Coping theorists argue that environmental factors affect how children perceive and respond to stressful events such as cancer. However, few studies have investigated how particular interventions can change coping behaviors. The active music engagement (AME) intervention was designed to counter stressful qualities of the in-patient hospital environment by introducing three forms of environmental support. The purpose of this multi-site randomized controlled trial was to determine the efficacy of the AME intervention on three coping-related behaviors (i.e. positive facial affect, active engagement, and initiation). Eighty-three participants, ages 4-7, were randomly assigned to one of three conditions: AME (n = 27), music listening (ML; n = 28), or audio storybooks (ASB; n = 28). Conditions were videotaped to facilitate behavioral data collection using time-sampling procedures. After adjusting for baseline differences, repeated measure analyses indicated that AME participants had a significantly higher frequency of coping-related behaviors compared with ML or ASB. Positive facial affect and active engagement were significantly higher during AME compared with ML and ASB (p<0.0001). Initiation was significantly higher during AME than ASB (p<0.05). This study supports the use of the AME intervention to encourage coping-related behaviors in hospitalized children aged 4-7 receiving cancer treatment. (c) 2007 John Wiley & Sons, Ltd.

This study explored staff perceptions of the role of physical environment in dementia care facilities in affecting resident's behaviors and staff care practice. We conducted focus groups with staff (n = 15) in two purposely selected care facilities in Vancouver, Canada. Focus group participants included nurses, care aides, recreation staff, administrative staff, and family. Data analysis revealed two themes: (a) a supportive physical environment contributes positively to both quality of staff care interaction and residents' quality of life and (b) an unsupportive physical environment contributes negatively to residents' quality of life and thereby makes the work of staff more challenging. The staff participants collectively viewed that comfort, familiarity, and an organized space were important therapeutic resources for supporting the well-being of residents. Certain behaviors of residents were influenced by poor environmental factors, including stimulation overload, safety risks, wayfinding challenge, and rushed care This study demonstrates the complex interrelationships among the dementia care setting's physical environment, staff experiences, and residents' quality of life. © The Author(s) 2014.

The World Health Organization and several governments encourage medical self-care (including self-medication) for minor illnesses. Accordingly, the factors that influence self-care have received research attention, with socioeconomic status identified as one such predictor. Although studies have examined the relationship between socioeconomic status and quality of life (QOL) in patients suffering from respiratory allergies or chronic illnesses, the relationship between QOL and self-care behavior for the common cold, the most common illness seen in primary care, has not been examined. Therefore, we investigated the relationship between QOL and self-care behavior in individuals suffering from the common cold. We distributed questionnaires to 499 people who attended an annual public health checkup in Kasama city, Japan. Valid questionnaires were received from 398 participants (mean age = 59.0, SD = 15.8, range = 24-87 years; 61.4 % women). The materials included a question relating to typical actions taken when treating a common cold (self-care or visiting a health clinic), demographics, and the Short Form-8™ (SF-8™)-an 8-item survey that assesses health-related quality of life (HRQOL). The association of care action and HRQOL were investigated using Mann-Whitney U tests with a significance level of p < 0.05. The mean scores for the Physical Functioning, Role-Physical, Bodily Pain, Social Functioning, Role-Emotional, and Physical Component Summary score of the SF-8™ were significantly higher among the self-care group than the group that preferred visiting a clinic. HRQOL among individuals who engage in self-care when treating the common cold was observed to be significantly higher than among individuals who preferred to attend a health clinic. It is unclear whether self-care behavior affects QOL, or whether QOL affects self-care behavior; however, this finding highlights the importance of the relationship between QOL and self-care behavior. Additional studies should be conducted in order to investigate the direction of causality between self-care behaviors and QOL further.

Cognitive and affective empathy in children with conduct problems: additive and interactive effects of callous-unemotional traits and autism spectrum disorders symptoms.

PubMed

Pasalich, Dave S; Dadds, Mark R; Hawes, David J

2014-11-30

Callous-unemotional (CU) traits and autism spectrum disorders (ASD) symptoms are characterized by problems in empathy; however, these behavioral features are rarely examined together in children with conduct problems. This study investigated additive and interactive effects of CU traits and ASD symptoms in relation to cognitive and affective empathy in a non-ASD clinic-referred sample. Participants were 134 children aged 3 to 9 years (M=5.60; 79% boys) with oppositional defiant/conduct disorder, and their parents. Clinicians, teachers, and parents reported on dimensions of child behavior, and parental reports of family dysfunction and direct observations of parental warmth/responsiveness assessed quality of family relationships. Results from multiple regression analysis showed that, over and above the effects of child conduct problem severity and quality of family relationships, both ASD symptoms and CU traits were uniquely associated with deficits in cognitive empathy. Moreover, CU traits demonstrated an independent association with affective empathy, and this relationship was moderated by ASD symptoms. That is, there was a stronger negative association between CU traits and affective empathy at higher versus lower levels of ASD symptoms. These findings suggest including both CU traits and ASD-related social impairments in models delineating the atypical development of empathy in children with conduct problems.

2015-01-01

Cancer patients suffer high levels of affective and cognitive disturbances, which have been attributed to diagnosis-related distress, impairment of quality of life, and side effects of primary treatment. An inflammatory microenvironment is also a feature of the vast majority of solid tumors. However, the ability of tumor-associated biological processes to affect the central nervous system (CNS) has only recently been explored in the context of symptoms of depression and cognitive disturbances. In this review, we summarize the burgeoning evidence from rodent cancer models that solid tumors alter neurobiological pathways and subsequent behavioral processes with relevance to affective and cognitive disturbances reported in human cancer populations. We consider, in parallel, the evidence from human clinical cancer research demonstrating that affective and cognitive disturbances are common in some malignancies prior to diagnosis and treatment. We further consider the underlying neurobiological pathways, including altered neuroinflammation, tryptophan metabolism, prostaglandin synthesis and associated neuroanatomical changes, that are most strongly implicated in the rodent literature and supported by analogous evidence from human cancer populations. We focus on the implications of these findings for behavioral researchers and clinicians, with particular emphasis on methodological issues and areas of future research. PMID:25958011

Do infants influence their quality of care? Infants' communicative gestures predict caregivers' responsiveness.

Vallotton, Claire D

2009-12-01

Infants' effects on adults are a little studied but important aspect of development. What do infants do that increases caregiver responsiveness in childcare environments? Infants' communicative behaviors (i.e. smiling, crying) affect mothers' responsiveness; and preschool children's language abilities affect teachers' responses in the classroom setting. However, the effects of infants' intentional communications on either parents' or non-parental caregivers' responsiveness have not been examined. Using longitudinal video data from an infant classroom where infant signing was used along with conventional gestures (i.e. pointing), this study examines whether infants' use of gestures and signs elicited greater responsiveness from caregivers during daily interactions. Controlling child age and individual child effects, infants' gestures and signs used specifically to respond to caregivers elicited more responsiveness from caregivers during routine interactions. Understanding the effects of infants' behaviors on caregivers is critical for helping caregivers understand and improve their own behavior towards children in their care.

Satisfaction with environmental change: an empirical analysis of attitudes toward air quality by recent interstate migrants

1984-09-01

How (and whether) people perceive environmental change is a question that economists have generally chosen to finesse rather than explore. The three components of attitudes (cognitive, affective, behavioral) are identified and a satisfaction metric is used to evaluate the nonbehavioral components for recent in-migrants to Oregon. An interaction model is used to relate changes in satisfaction to changes in air quality and to personal characteristics of the migrants. In general, a valid cognitive dimension exists; changes in satisfaction are in fact consistent with changes in air quality data. 34 references, 7 tables.

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder with origins early in life. There is growing evidence that individual differences in temperament reactivity are predictive of ADHD symptoms, yet little is known about the relations between temperament reactivity in early infancy and later ADHD symptoms or the combined effect of reactivity with early environmental factors on ADHD symptom development. Using a 9-year prospective longitudinal design, this study tested the independent and interactive contributions of infant reactivity and maternal caregiving behaviors (MCB) on parent- and teacher-reported childhood ADHD symptoms. Participants included 291 children (132 male; 159 female) who participated in a larger study of temperament and social-emotional development. Reactivity was assessed by behavioral observation of negative affect, positive affect, and motor activity during novel stimuli presentations at 4 months of age. MCB were observed during a series of semistructured mother-infant tasks at 9 months of age. Finally, ADHD symptoms were assessed by parent- and teacher-report questionnaires at 7 and 9 years, respectively. Reactivity was predictive of ADHD symptoms, but results were sex specific. For boys, infant motor activity was positively predictive of later ADHD symptoms, but only at lower quality MCB. For girls, infant positive affect was positively predictive of later ADHD symptoms at lower quality MCB, and-unexpectedly-infant positive affect and motor activity were negatively predictive of later ADHD symptoms at higher quality MCB. These results point to early parenting as a moderating factor to mitigate temperament-related risk for later ADHD, suggesting this as a potential intervention target to mitigate risk for ADHD among reactive infants. © 2018 Association for Child and Adolescent Mental Health.

Factors affecting sampling behavior of cattle are poorly understood. The objectives of this study were to measure the effects of variation in feed quality on the feeding behavior of Holstein dairy heifers. Thirty-two heifers were housed in 4 groups of 8. Each group pen had 8 distinct feeding stations. The total mixed ration (TMR) provided was low energy (TMR-L), moderate energy (TMR-M), or high energy (TMR-H). During trial 1 (d 1 to 8), heifers were offered a uniform baseline diet (TMR-M in all 8 feeding stations) interspaced with 2 uniform test diets on d 3 and 6 (TMR-L or TMR-H in all 8 feeding stations). During trial 2 (d 9 to 17) heifers were offered a nonuniform baseline diet (7 feeding stations with TMR-L and 1 feeding station with TMR-H) interspaced with 3 uniform test diets on d 11, 14, and 17 (TMR-L, TMR-M, or TMR-H in all 8 feeding stations). Heifers were observed in pairs (n=16) for 15 min following delivery of fresh feed. Relative to the uniform baseline period of trial 1, 31% fewer switches occurred between feeding stations when offered TMR-H and 51% more switches when offered TMR-L. Relative to the nonuniform baseline of trial 2, 49% fewer, 27% fewer, and 25% more switches occurred during the TMR-H, TMR-M, and TMR-L treatments, respectively. In general, when heifers were offered a diet that was lower in energy density than that previously experienced, they spent less time at each feeding station and when offered a higher energy diet, heifers spent more time at each feeding station. The greater the contrast in energy density between the test and baseline diets, the greater the change in the behavioral response. Competitive interactions at the feed bunk were most frequent when TMR quality varied among the 8 feeding stations; during the nonuniform baseline period of trial 2, the number of competitive interactions was over 3.5 times higher than during all uniform dietary treatments. In summary, dairy heifers sample feed quality by changing feeding locations at the feed bunk and this sampling behavior is affected by variation in diet quality along the feed bunk and across days.

Smith-Schrandt, Heather L; Ojanen, Tiina; Gesten, Ellis; Feldman, Marissa A; Calhoun, Casey D

2011-01-01

In accord with increasing recognition of the situation specificity of childhood social behaviors, individual and contextual differences in children's responses to potential peer conflict were examined (hostile attribution, behavioral strategies, and affective reactions; N = 367, 9-12 years, 197 girls). Situational cues from 2 sources, the antagonist and a witnessing best friend, were designed to suggest the antagonist's intentions. Multilevel modeling indicated that children's responses generally varied more according to cues from the antagonist than friend, but the latter also affected responses, especially when conflicting with other situational information. Cognitive and affective responses were also influenced by gender, social goals, friendship quality, and self-efficacy for peer interaction. Findings provide theoretical insight on the context of peer conflict. © 2011 The Authors. Child Development © 2011 Society for Research in Child Development, Inc.

Spatial attention enhances the selective integration of activity from area MT.

PubMed

Masse, Nicolas Y; Herrington, Todd M; Cook, Erik P

2012-09-01

Distinguishing which of the many proposed neural mechanisms of spatial attention actually underlies behavioral improvements in visually guided tasks has been difficult. One attractive hypothesis is that attention allows downstream neural circuits to selectively integrate responses from the most informative sensory neurons. This would allow behavioral performance to be based on the highest-quality signals available in visual cortex. We examined this hypothesis by asking how spatial attention affects both the stimulus sensitivity of middle temporal (MT) neurons and their corresponding correlation with behavior. Analyzing a data set pooled from two experiments involving four monkeys, we found that spatial attention did not appreciably affect either the stimulus sensitivity of the neurons or the correlation between their activity and behavior. However, for those sessions in which there was a robust behavioral effect of attention, focusing attention inside the neuron's receptive field significantly increased the correlation between these two metrics, an indication of selective integration. These results suggest that, similar to mechanisms proposed for the neural basis of perceptual learning, the behavioral benefits of focusing spatial attention are attributable to selective integration of neural activity from visual cortical areas by their downstream targets.

There is a lack of research on implementation of person-centered care in nursing home care. The purpose of this study was to assess the implementation of the Veder contact method (VCM), a new person-centered method using theatrical, poetic and musical communication for application in 24-hr care. Caregivers (n = 136) and residents (n = 141) participated in a 1-year quasi-experimental study. Foundation Theater Veder implemented VCM on six experimental wards and rated implementation quality. Six control wards delivered care-as-usual. Before and after implementation, caregiver behavior was assessed during observations using the Veder-observation list and Quality of Caregivers' Behavior-list. Caregiver attitude was rated with the Approaches to Dementia Questionnaire. Quality of life, behavior, and mood of the residents were measured with QUALIDEM, INTERACT and FACE. Residents' care plans were examined for person-centered background information. Significant improvements in caregivers' communicative behavior (i.e., the ability to apply VCM, establishing positive interactions) and some aspects of residents' behavior and quality of life (i.e., positive affect, social relations) were found on the experimental wards with a high implementation score, as compared to the experimental wards with a low implementation score, and the control wards. No significant differences were found between the groups in caregivers' attitudes, residents' care plans, or mood. The positive changes in caregivers' behavior and residents' well-being on the high implementation score wards confirm the partly successful VCM implementation. Distinguishing between wards with a high and low implementation score provided insight into factors which are crucial for successful implementation. © The Author(s) 2018.

Human Factors Affecting the Patient's Acceptance of Wireless Biomedical Sensors

NASA Astrophysics Data System (ADS)

Fensli, Rune; Boisen, Egil

In monitoring arrhythmia, the quality of medical data from the ECG sensors may be enhanced by being based on everyday life situations. Hence, the development of wireless biomedical sensors is of growing interest, both to diagnose the heart patient, as well as to adjust the regimen. However, human factors such as emotional barriers and stigmatization, may affect the patient's behavior while wearing the equipment, which in turn may influence quality of data. The study of human factors and patient acceptance is important both in relation to the development of such equipment, as well as in evaluating the quality of data gathered from the individual patient. In this paper, we highlight some important aspects in patient acceptance by comparing results from a preliminary clinical trial with patients using a wireless ECG sensor for three days out-of-hospital service, to available published results from telehomecare projects, and discuss important aspects to be taken into account in future investigations.

Relations of Inhibition and Emotion-Related Parenting to Young Children's Prosocial and Vicariously Induced Distress Behavior.

Children's prosocial behavior and personal distress are likely affected by children's temperament as well as parenting quality. In this study, we examined bidirectional relations from age 30 to 42 months between children's (N = 218) prosocial or self-focused (presumably distressed) reactions to a relative stranger's distress and both supportive emotion-related maternal reactions to children's emotions and children's shyness/inhibition. When controlling for 30-month prosocial behavior and personal distress behavior, maternal supportive (emotion-focused and problem-focused) reactions were positively related to prosocial behavior and marginally negatively related to children's personal distress behaviors and shyness/inhibition at 42 months. Thirty-month personal distress behavior predicted greater shyness/inhibition at 42 months, and 30-month shyness/inhibition was negatively related to prosocial behavior at 30 months. © 2017 The Authors.

Selecting appropriate stimuli to induce emotional states is essential in affective research. Only a few standardized affective stimulus databases have been created for auditory, language, and visual materials. Numerous studies have extensively employed these databases using both behavioral and neuroimaging methods. However, some limitations of the existing databases have recently been reported, including limited numbers of stimuli in specific categories or poor picture quality of the visual stimuli. In the present article, we introduce the Nencki Affective Picture System (NAPS), which consists of 1,356 realistic, high-quality photographs that are divided into five categories (people, faces, animals, objects, and landscapes). Affective ratings were collected from 204 mostly European participants. The pictures were rated according to the valence, arousal, and approach-avoidance dimensions using computerized bipolar semantic slider scales. Normative ratings for the categories are presented for each dimension. Validation of the ratings was obtained by comparing them to ratings generated using the Self-Assessment Manikin and the International Affective Picture System. In addition, the physical properties of the photographs are reported, including luminance, contrast, and entropy. The new database, with accompanying ratings and image parameters, allows researchers to select a variety of visual stimulus materials specific to their experimental questions of interest. The NAPS system is freely accessible to the scientific community for noncommercial use by request at http://naps.nencki.gov.pl .

High-risk unsafe behaviors (HRUBs) have been known as the main cause of occupational accidents. Considering the financial and societal costs of accidents and the limitations of available resources, there is an urgent need for managing unsafe behaviors at workplaces. The aim of the present study was to find strategies for decreasing the rate of HRUBs using an integrated approach of safety behavior sampling technique and Bayesian networks analysis. A cross-sectional study. The Bayesian network was constructed using a focus group approach. The required data was collected using the safety behavior sampling, and the parameters of the network were estimated using Expectation-Maximization algorithm. Using sensitivity analysis and belief updating, it was determined that which factors had the highest influences on unsafe behavior. Based on BN analyses, safety training was the most important factor influencing employees' behavior at the workplace. High quality safety training courses can reduce the rate of HRUBs about 10%. Moreover, the rate of HRUBs increased by decreasing the age of employees. The rate of HRUBs was higher in the afternoon and last days of a week. Among the investigated variables, training was the most important factor affecting safety behavior of employees. By holding high quality safety training courses, companies would be able to reduce the rate of HRUBs significantly.

Association between Personality Traits and Sleep Quality in Young Korean Women

2015-01-01

Personality is a trait that affects behavior and lifestyle, and sleep quality is an important component of a healthy life. We analyzed the association between personality traits and sleep quality in a cross-section of 1,406 young women (from 18 to 40 years of age) who were not reporting clinically meaningful depression symptoms. Surveys were carried out from December 2011 to February 2012, using the Revised NEO Personality Inventory and the Pittsburgh Sleep Quality Index (PSQI). All analyses were adjusted for demographic and behavioral variables. We considered beta weights, structure coefficients, unique effects, and common effects when evaluating the importance of sleep quality predictors in multiple linear regression models. Neuroticism was the most important contributor to PSQI global scores in the multiple regression models. By contrast, despite being strongly correlated with sleep quality, conscientiousness had a near-zero beta weight in linear regression models, because most variance was shared with other personality traits. However, conscientiousness was the most noteworthy predictor of poor sleep quality status (PSQI≥6) in logistic regression models and individuals high in conscientiousness were least likely to have poor sleep quality, which is consistent with an OR of 0.813, with conscientiousness being protective against poor sleep quality. Personality may be a factor in poor sleep quality and should be considered in sleep interventions targeting young women. PMID:26030141

Does Caregiver Behavior Mediate the Relationship Between Cultural Individualism and Infant Pain at 12 Months of Age?

2016-12-01

This study aimed to understand the relationship between caregiver culture and infant pain expression at the 12-month immunization and discern if a mechanism subsuming this relationship was the quality of caregiver behaviors (emotional availability). Infants (N = 393) with immunization data at 12 months of age were examined. On the basis of the Development of Infant Acute Pain Responding model, a mediation model was developed to examine how caregiver behaviors mediate the relationship between caregiver heritage culture and infant pain. Culture was operationalized by an objectively derived quantification of caregivers' self-reported heritage culture's individualism. Two mediation models were estimated, examining infant pain expression at 1 and 2 minutes post-needle. Caregivers who self-reported heritage cultures that were more highly individualistic tended to show greater emotional availability, which in turn predicted decreased infant pain expression at 1 and 2 minutes post-needle. The present findings further our understanding of one mechanism by which caregiver culture affects infant acute pain expression. Adding to the literature examining direct relationships between culture and infant immunization pain, this article proposes the quality of caregiver behaviors as a mechanism by which culture affects infant acute pain expression at 12 months of age. Results support the proposed mechanism and inform our understanding of the role of caregiver culture in the infant pain context. Copyright © 2016 American Pain Society. Published by Elsevier Inc.

The EMO-Model: An Agent-Based Model of Primate Social Behavior Regulated by Two Emotional Dimensions, Anxiety-FEAR and Satisfaction-LIKE

Agent-based models provide a promising tool to investigate the relationship between individuals’ behavior and emerging group-level patterns. An individual’s behavior may be regulated by its emotional state and its interaction history with specific individuals. Emotional bookkeeping is a candidate mechanism to keep track of received benefits from specific individuals without requiring high cognitive abilities. However, how this mechanism may work is difficult to study in real animals, due to the complexity of primate social life. To explore this theoretically, we introduce an agent-based model, dubbed EMO-model, in which we implemented emotional bookkeeping. In this model the social behaviors of primate-like individuals are regulated by emotional processes along two dimensions. An individual’s emotional state is described by an aversive and a pleasant dimension (anxiety and satisfaction) and by its activating quality (arousal). Social behaviors affect the individuals’ emotional state. To implement emotional bookkeeping, the receiver of grooming assigns an accumulated affiliative attitude (LIKE) to the groomer. Fixed partner-specific agonistic attitudes (FEAR) reflect the stable dominance relations between group members. While the emotional state affects an individual’s general probability of executing certain behaviors, LIKE and FEAR affect the individual’s partner-specific behavioral probabilities. In this way, emotional processes regulate both spontaneous behaviors and appropriate responses to received behaviors, while emotional bookkeeping via LIKE attitudes regulates the development and maintenance of affiliative relations. Using an array of empirical data, the model processes were substantiated and the emerging model patterns were partially validated. The EMO-model offers a framework to investigate the emotional bookkeeping hypothesis theoretically and pinpoints gaps that need to be investigated empirically. PMID:24504194

Drosophila Ovipositor Extension in Mating Behavior and Egg Deposition Involves Distinct Sets of Brain Interneurons

PubMed Central

Kimura, Ken-ichi; Sato, Chiaki; Koganezawa, Masayuki; Yamamoto, Daisuke

2015-01-01

Oviposition is a female-specific behavior that directly affects fecundity, and therefore fitness. If a fertilized female encounters another male that she has evaluated to be of better quality than her previous mate, it would be beneficial for her to remate with this male rather than depositing her eggs. Females who decided not to remate exhibited rejection behavior toward a courting male and engaged in oviposition. Although recent studies of Drosophila melanogaster identified sensory neurons and putative second-order ascending interneurons that mediate uterine afferents affecting female reproductive behavior, little is known about the brain circuitry that selectively activates rejection versus oviposition behaviors. We identified the sexually dimorphic pC2l and female-specific pMN2 neurons, two distinct classes of doublesex (dsx)-expressing neurons that can initiate ovipositor extension associated with rejection and oviposition behavior, respectively. pC2l interneurons, which induce ovipositor extrusion for rejection in females, have homologues that control courtship behavior in males. Activation of these two classes of neurons appears to be mutually exclusive and each governs hierarchical control of the motor program in the VNC either for rejection or oviposition, contributing centrally to the switching on or off of the alternative motor programs.

A considerable portion of daily thought is spent in mind wandering. This behavior has been related to positive (eg, future planning, problem solving) and negative (eg, unhappiness, impaired cognitive performance) outcomes. Based on previous research suggesting future-oriented (ie, prospective) mind wandering may support autobiographical planning and self-regulation, this study examined associations between hourly mind wandering and moderate-to-vigorous physical activity (MVPA), and the impact of affect and daily sleep on these relations. College-aged adults (N=33) participated in a mobile phone-delivered ecological momentary assessment study for 1 week. Sixteen hourly prompts assessing mind wandering and affect were delivered daily via participants' mobile phones. Perceived sleep quality and duration was assessed during the first prompt each day, and participants wore an ActiGraph accelerometer during waking hours throughout the study week. Study findings suggest present-moment mind wandering was positively associated with future MVPA (P=.03), and this relationship was moderated by affective state (P=.04). Moreover, excessive sleep the previous evening was related to less MVPA across the following day (P=.007). Further, mind wandering was positively related to activity only among those who did not oversleep (P=.007). Together, these results have implications for multiple health behavior interventions targeting physical activity, affect, and sleep. Researchers may also build on this work by studying these relationships in the context of other important behaviors and psychosocial factors (eg, tobacco use, depression, loneliness).

Social Brains in Context: Lesions Targeted to the Song Control System in Female Cowbirds Affect Their Social Network

Social experiences can organize physiological, neural, and reproductive function, but there are few experimental preparations that allow one to study the effect individuals have in structuring their social environment. We examined the connections between mechanisms underlying individual behavior and social dynamics in flocks of brown-headed cowbirds (Molothrus ater). We conducted targeted inactivations of the neural song control system in female subjects. Playback tests revealed that the lesions affected females' song preferences: lesioned females were no longer selective for high quality conspecific song. Instead, they reacted to all cowbird songs vigorously. When lesioned females were introduced into mixed-sex captive flocks, they were less likely to form strong pair-bonds, and they no longer showed preferences for dominant males. This in turn created a cascade of effects through the groups. Social network analyses showed that the introduction of the lesioned females created instabilities in the social structure: males in the groups changed their dominance status and their courtship patterns, and even the competitive behavior of other female group-mates was affected. These results reveal that inactivation of the song control system in female cowbirds not only affects individual behavior, but also exerts widespread effects on the stability of the entire social system.

The overwhelming statistics of crime against women affect their perceptions and quality of life. The media have a significant effect on both perceptions and behavior. The manner, therefore, in which fictional victims are portrayed could affect perceptions of control in real-life women fearing victimization and in their potential assailants. Popular crime-drama movies and the difference between male and female behaviors were examined in this pilot study. A total of 65 responses were evaluated from a random sample of film videos. Active attempts to gain control were exhibited by 81% of the male responses, whereas only 17% of the women did so, chi 2 (1, N = 65) = 28.99, p less than .001. The relationship of results and myths concerning women as victims is discussed.

Understanding social and behavioral drivers and impacts of air quality sensor use.

2018-04-15

Lower-cost air quality sensors (hundreds to thousands of dollars) are now available to individuals and communities. This technology is undergoing a rapid and fragmented evolution, resulting in sensors that have uncertain data quality, measure different air pollutants and possess a variety of design attributes. Why and how individuals and communities choose to use sensors is arguably influenced by social context. For example, community experiences with environmental exposures and health effects and related interactions with industry and government can affect trust in traditional air quality monitoring. To date, little social science research has been conducted to evaluate why or how sensors, and sensor data, are used by individuals and communities, or how the introduction of sensors changes the relationship between communities and air quality managers. This commentary uses a risk governance/responsible innovation framework to identify opportunities for interdisciplinary research that brings together social scientists with air quality researchers involved in developing, testing, and deploying sensors in communities. Potential areas for social science research include communities of sensor users; drivers for use of sensors and sensor data; behavioral, socio-political, and ethical implications of introducing sensors into communities; assessing methods for communicating sensor data; and harnessing crowdsourcing capabilities to analyze sensor data. Social sciences can enhance understanding of perceptions, attitudes, behaviors, and other human factors that drive levels of engagement with and trust in different types of air quality data. New transdisciplinary research bridging social sciences, natural sciences, engineering, and design fields of study, and involving citizen scientists working with professionals from a variety of backgrounds, can increase our understanding of air sensor technology use and its impacts on air quality and public health.

Review of the literature suggests that hair color influences the quality of interpersonal interactions. Results of a factorially designed study show that while women helped confederates equally regardless of their gender, men helped women more than they helped men. Hair color of confederates was not shown to affect helping behavior. (Author/ABB)

Dairy animals are subjected to a number of potential stressors throughout their lives, including daily interactions with humans. The quality of these interactions may have direct consequences for the animal undergoing the experience, but if such events occur during gestation it may also affect the developing fetus. This study examined the effects of differential handling during mid-gestation in 40 twin-bearing Saanen×Toggenburg primiparous goats. Between days 80 and 115 of gestation (gestation=150 days), goats were subjected to aversive (AVS, n=13), gentle (GEN, n=13) or minimal (M, n=14) handling protocols for 10 minute periods twice daily. The control (M) group did not receive handling treatments and all goats received normal husbandry procedures outside treatment periods. Salivary cortisol measured during the treatment period was higher in AVS goats (mean cortisol (sem) in pg/μl: AVS: 176.7 (18.2), GEN: 119.6 (11.1), M: 126.5 (13.7); P=0.007). Data collection was focussed on mother-offspring behaviors 2h post-partum, placental morphology and colostrum quality. AVS goats were the only treatment group to suffer fetal loss (16% loss vs 0% in GEN and M, P=0.05). Treatment also influenced placental morphology with a tendency for fewer cotyledons evident in placentae from the aversive treatment (AVS: 87.9 (7.8), GEN: 107.1 (7.9), M: 112.1 (9.3), P=0.093), and significantly fewer medium sized cotyledons (AVS: 67.6 (7.8), GEN: 89.3 (6.4), M: 84.3 (5.4), P=0.042). GEN goats displayed more grooming and nosing behaviors towards their young during the first 2h post-partum (grooming: GEN: 89.3% (7.1), AVS: 72.6% (7.7), M: 63.4% (9.0), P=0.045; nosing frequency: GEN: 58.8 (12.5), AVS: 28.6 (11.1), M: 34.7 (6.5), P=0.021). There was an overall trend for kids from mothers experiencing the AVS treatment to take longer to stand, reach the udder and suck compared to kids from GEN and M treatment groups. Treatment significantly affected latency to perform play behavior, with kids from AVS goats taking on average 25 min longer to play for the first time than kids from GEN and M treatment groups (P<0.001). The results show that handling during gestation affects placental morphology, fetal survival and post-partum maternal behaviors, and influences kid behavioral development. Such results have important animal welfare implications, demonstrating that negative handling of pregnant females results in poorer placental quality with potential for fetal loss. It also demonstrates the beneficial effects of positive handling on enhancement of maternal behaviors. Copyright © 2016 Elsevier Inc. All rights reserved.

Neural and behavioral correlates of food allergy.

Costa-Pinto, Frederico Azevedo; Basso, Alexandre Salgado

2012-01-01

Food allergy accounts for a great number of reactions leading to diminished quality of life in western countries. There has been an abundance of reports of behavioral changes, as well as psychiatric conditions associated with food allergy over the past decades. Most of this field inspired little medical attention for its lack of a solid scientific ground. We review the literature on the association of food allergy and brain activity, leading to changes in emotion and behavior. Moreover, we describe an experimental paradigm employed to dissect the biological relevance of this association. Mice allergic to ovalbumin avoid a palatable sweet solution in order to escape contact with antigen. This choice is associated with increased levels of anxiety, compatible with a conflicting situation. These responses are associated with increased activity in brain areas associated with emotional and affective behavior, which are also important for anxiety and stress responses. Higher levels of corticosterone accompany these changes in behavior. These responses are mediated by specific antibodies and prevented by depletion or immunological tolerance. They are also partially mediated by C-sensitive afferents and mast cells. Far from anecdote, neural repercussions of food allergy should be considered when planning a therapeutic strategy in affected individuals. Copyright © 2012 S. Karger AG, Basel.

Meta-analytic procedures were used to test the effects of violent video games on aggressive behavior, aggressive cognition, aggressive affect, physiological arousal, empathy/desensitization, and prosocial behavior. Unique features of this meta-analytic review include (a) more restrictive methodological quality inclusion criteria than in past meta-analyses; (b) cross-cultural comparisons; (c) longitudinal studies for all outcomes except physiological arousal; (d) conservative statistical controls; (e) multiple moderator analyses; and (f) sensitivity analyses. Social-cognitive models and cultural differences between Japan and Western countries were used to generate theory-based predictions. Meta-analyses yielded significant effects for all 6 outcome variables. The pattern of results for different outcomes and research designs (experimental, cross-sectional, longitudinal) fit theoretical predictions well. The evidence strongly suggests that exposure to violent video games is a causal risk factor for increased aggressive behavior, aggressive cognition, and aggressive affect and for decreased empathy and prosocial behavior. Moderator analyses revealed significant research design effects, weak evidence of cultural differences in susceptibility and type of measurement effects, and no evidence of sex differences in susceptibility. Results of various sensitivity analyses revealed these effects to be robust, with little evidence of selection (publication) bias.

2,2',4,4',5-Pentabromodiphenyl ether (BDE-99) is a brominated flame retardant congener that has pervaded global food chains, being reported in avian egg and tissue samples throughout the world. Its effects on birds are not well known, but there is evidence in exposed mammals that it directly mediates and causes neurotoxicity, alters thyroid hormone homeostasis, and lowers sex steroid hormone concentrations. In birds, those processes could disrupt the song-control system and male mating behavior. In this study, the effects of nestling exposure to environmentally relevant levels of BDE-99 were assessed in a model songbird species, the zebra finch (Taeniopygia guttata). A tissue residue study in which zebra finch nestlings were orally exposed to 0, 2.5, 15.8, or 50.7 ng BDE-99/g body weight (bw) per day over the 21-day nesting period validated dosing methods and confirmed dose levels were environmentally relevant (332.7 ± 141.0 to 4450.2 ± 1396.2 ng/g plasma lipid). A full-scale study exposing nestlings to 0, 2.5, 15.8, 50.7, or 173.8 ng BDE-99/g bw/day was carried out to investigate long-term effects of BDE-99 on the adult song-control nuclei volumes, song quality, and male mating behavior. Early exposure to BDE-99 had significant effects on male mating behavior and the response of clean experienced females to exposed males. There was no effect on male song-control nuclei or song quality, and there were nondose-dependent effects on female song-control nuclei. The results demonstrate that early exposure to environmentally relevant levels of BDE-99 affects the behavior of zebra finches.

Behavioral intervention in the treatment of obesity in children and adolescents: implications for Mexico.

Pediatric obesity is a worldwide health epidemic affecting both developed and developing countries. Mexico ranks second to the United States in rates of pediatric obesity. Obesity among youth has immediate and long-term consequences on physical and psychosocial development, including cardiovascular, respiratory, and health-related quality of life. Eventual amelioration of this epidemic will require change at the level of the family and community, along with policy initiatives to support healthier eating and activity habits. Evidence-based interventions for overweight/obese youth include family-based lifestyle programs that incorporate attention to diet quantity and quality, physical activity, sedentary behavior, and behavioral strategies to support change. While much of this research has been conducted in the United States, several recent studies suggest the efficacy of similar approaches for youth in Mexico. © The Author(s) 2016.

This study investigated quality of life and adjustment mechanisms in parents of children with Attention-Deficit/Hyperactivity Disorder (ADHD). Ninety parents of children with ADHD completed a sociodemographic questionnaire and self-assessment scales to measure their perceived stress, social support, sense of control, coping strategies and quality of life. ADHD in children negatively affected parents' quality of life, especially their psychological well-being and personal fulfillment. Family and couple relationships, as well as daily life activities, were also affected. The severity of the disorder, perceiving the situation as a threat or a loss, feeling guilty and holding on to irrational beliefs were related to emotion-focused coping strategies and to a poorer quality of life. Furthermore, hyperactivity index and stress ratings relative to perceiving the situation as a threat or a loss, and adopting emotion-focused coping strategies, predicted poorer quality of life. In contrast, perceiving the situation as challenging was related to a greater sense of control and personal fulfillment. Moreover, perceiving the situation as challenging and adopting problem-focused coping strategies predicted better quality of life. The findings highlight the negative effects of ADHD on parent psychological adjustment and underline the need to recommend training programs that improve parenting skills, parents' perceptions concerning their child's behavior disorder and parental functioning.

To evaluate differences and changes in quality of life (QoL), lifestyle behavior and employment experience of young in comparison to midlife adults in response to early stage gynecologic cancer diagnoses. 263 patients, divided into two age groups (Group A: ≤ 45 and Group B: >45 years), were interviewed on their QoL, lifestyle behavior (dietary habits, tobacco and alcohol use, physical activity) and employment experience (employment status and working time) at diagnosis and within 4 years from the treatment. The QoL was evaluated by European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire C30 (QLQ-C30) and its specific modules for each cancer type (in particular endometrium, cervix, ovarian and breast). Global health status was significantly different between the two groups. In the younger age group a more relevant cancer interference on family life and social activities and a greater impact on perception of health status have been observed. Young women were more affected by fatigue, constipation, gastrointestinal symptoms, lymphedema, poor body image and impaired sexuality. Cancer diagnosis had a major negative impact on employment of younger patients. Conversely, younger patients had overall better health behavior. They reported a higher daily intake of fruits and vegetables, along with lower alcohol consumption, furthermore they were a little more physically active than midlife adults. To enhance quality of life and to promote healthy lifestyle behavior of female cancer patients, particularly in younger age, it is essential to assure multidisciplinary approaches with specific medical intervention and psychosocial supports. Indeed, midlife adults seem to have a more rapid adaptive tendency to return towards levels of well-being, following cancer diagnosis and treatment, than younger patients.

To identify mother-adolescent dyad profiles according to food-related parenting practices and to determine differences in diet quality, family meal frequency, life satisfaction, and sociodemographic characteristics. Cross-sectional study. Mothers and children were surveyed in their homes or at schools in Temuco, Chile. A total of 300 mothers (average age, 41.6 years) and their adolescent children (average age, 13.2 years; 48.7% female). Maternal feeding practices using the abbreviated Family Food Behavior Survey (AFFBS), life satisfaction, food-related and family life satisfaction, diet quality, and eating habits. Principal component factor analysis and confirmatory factor analysis were used to verify Family Food Behavior Survey components in mother and adolescent subsamples. Hierarchical cluster analysis was used to identify profiles. Three AFFBS components were detected: maternal control of child snacking behavior, maternal presence during eating, and child involvement in food consumption. Cluster analysis identified 3 mother-adolescent dyad profiles with different food-related parenting practices (P ≤ .001), mother (P ≤ .05) and child (P ≤ .001) diet quality, frequency of shared family meals (P ≤ .001), and mother (P ≤ .001) and child (P ≤ .05) life satisfaction levels. Results indicated that maternal well-being increased with an increased frequency of shared mealtime. Significantly, in contrast to the findings of previous studies, greater control over child eating habits was shown to affect adolescent well-being positively. These findings, among others, may contribute to the development of strategies for improving diet quality, overall well-being, and well-being in the food and family domains for all family members.

Study Objectives: To investigate the restorative quality of sleep and daytime functioning in sleepwalking adult patients in comparison with controls. Design: Prospective case-control study. Setting: Data were collected at the Sleep Disorders Center, Hôpital-Gui-de Chauliac, Montpellier, France between June 2007 and January 2011. Participants: There were 140 adult sleepwalkers (100 (median age 30 y, 55% male) in whom primary SW was diagnosed) who underwent 1 night of video polysomnography. All patients participated in a standardized clinical interview and completed a battery of questionnaires to assess clinical characteristics of parasomnia, daytime sleepiness, fatigue, insomnia, depressive and anxiety symptoms, and health-related quality of life. Results were compared with those of 100 sex- and age-matched normal controls. Interventions: N/A. Measurements and Results: Of the sleepwalkers, 22.3% presented with daily episodes and 43.5% presented with weekly episodes. Median age at sleepwalking onset was 9 y. Familial history of sleepwalking was reported in 56.6% of sleepwalkers and violent sleep related behaviors in 57.9%, including injuries requiring medical care for at least one episode in 17%. Significant associations were found between sleepwalking and daytime sleepiness, fatigue, insomnia, depressive and anxiety symptoms, and altered quality of life. Early-onset sleepwalkers had higher frequency of violent behaviors and injuries. Sleepwalkers with violent behaviors had higher frequency of sleep terrors and triggering factors, with greater alteration in health-related quality of life. Conclusion: Adult sleepwalking is a potentially serious condition that may induce violent behaviors, self-injury or injury to bed partners, sleep disruption, excessive daytime sleepiness, fatigue, and psychological distress, all of which affect health-related quality of life.

Strangers in sync: Achieving embodied rapport through shared movements

PubMed Central

Vacharkulksemsuk, Tanya; Fredrickson, Barbara L.

2011-01-01

This paper examines the emergence of behavioral synchrony among strangers in the context of self-disclosure, and their path in predicting interaction quality. Specifically, we hypothesize that behavioral synchrony mediates the direct effect of self-disclosure on the development of embodied rapport. Same-sex stranger pairs (n=94) were randomly assigned to a videorecorded self-disclosure or control condition, and afterward each member rated their social interaction. Following the procedure used by Bernieri, Reznick, & Rosenthal (1988), two trained judges independently watched each video record and rated each pair interaction on behavioral synchrony. Bootstrapping analyses provide support for the hypothesized mediating effect of behavioral synchrony, which emerged as independent of the effects of self-other overlap and positive affect. The authors discuss implications of behavioral synchrony for relationship formation processes and the inevitable entwinement of behavior and judgments in light of embodied cognition. PMID:22389521

This experiment aimed to evaluate the effects of different housing systems on behavioral activities, welfare and meat quality of fast-growing broilers. Two hundred broilers were allocated into two housing systems: indoor housing vs indoor with outdoor access. Their general behavior (feeding, drinking, fighting, standing, lying, walking, investigating, dust-bathing and preening) was observed, and tonic immobility, fluctuating asymmetry of legs and wings were measured, and meat quality was analyzed. The results showed that the indoor-housed broilers with outdoor access had significant higher standing, walking, investigating, dust-bathing and preening than those indoor only. However, farming system was not found to significantly affect their feeding, drinking and fighting activities (p>0.05). The value of FA of tibia length of the broilers with outdoor access was significantly lower than that of the indoor-housed birds (1.57±1.30 vs 2.76±1.40, p<0.05), while no difference was found for the value of FA in tibia diameter and wing length (p>0.05). TI of the broilers with outdoor access was 165.5 that was significantly higher than that (147.2) of the indoor birds (p<0.05). However, death rate in the outdoor run groups was significantly higher than that of the indoor ones (2.0±0.81 vs 4.0±0.82, p<0.05). Meat quality was not affected by the two farming systems. It can be concluded that the results of this study may suggest that the indoor housing with outdoor access provides enriched environment for broilers and facilitates the expression of natural behaviors of the broilers but resulted in poorer performance and higher death rate.

Animals' responses to potentially threatening factors can provide important information for their conservation. Group size and human presence are potentially threatening factors to primates inhabiting small reserves used for recreation. We tested these hypotheses by evaluating behavioral and physiological responses in two groups of mantled howler monkeys (Alouatta palliata mexicana) at the "Centro Ecológico y Recreativo El Zapotal", a recreational forest reserve and zoo located in the Mexican state of Chiapas. Both groups presented fission-fusion dynamics, splitting into foraging subgroups which varied in size among, but not within days. Neither subgroup size nor number of people had an effect on fecal cortisol. Out of 16 behavioral response variables tested, the studied factors had effects on six: four were affected by subgroup size and two were affected by number of people. With increasing subgroup size, monkeys increased daily path lengths, rested less, increased foraging effort, and used more plant individuals for feeding. As the number of people increased, monkeys spent more time in lower-quality habitat, and less time engaged in social interactions. Although fecal cortisol levels were not affected by the factors studied, one of the monkey groups had almost twice the level of cortisol compared to the other group. The group with higher cortisol levels also spent significantly more time in the lower-quality habitat, compared to the other group. Our results suggest that particular behavioral adjustments might allow howler monkeys at El Zapotal to avoid physiological stress due to subgroup size and number of people. However, the fact that one of the monkey groups is showing increased cortisol levels may be interpreted as a warning sign, indicating that an adjustment threshold is being reached, at least for part of the howler monkey population in this forest fragment. © 2013 Wiley Periodicals, Inc.

The Flint Community Resilience Group (Flint, Michigan USA) and the Centers for Disease Control and Prevention (CDC; Atlanta, Georgia USA) assessed behavioral health concerns among community members to determine the impact of lead contamination of the Flint, Michigan water supply. A Community Assessment for Public Health Emergency Response (CASPER) was conducted from May 17 through May 19, 2016 using a multi-stage cluster sampling design to select households and individuals to interview. One-half of households felt overlooked by decision makers. The majority of households self-reported that at least one member experienced more behavioral health concerns than usual. The prevalence of negative quality of life indicators and financial concerns in Flint was higher than previously reported in the Michigan 2012 and 2014 Behavioral Risk Factor Surveillance System (BRFSS) survey. The following can be considered to guide recovery efforts in Flint: identifying additional resources for behavioral health interventions and conducting follow-up behavioral health assessments to evaluate changes in behavioral health concerns over time; considering the impact of household economic factors when implementing behavioral health interventions; and ensuring community involvement and engagement in recovery efforts to ease community stress and anxiety.

Data suggest that adverse social determinants during adolescence can set in motion a lifetime of poor social and health outcomes. Vulnerable youths are at particularly high risk in this regard. To identify and assess the current evidence base for adolescent-focused interventions designed to influence adulthood preparation that could affect longer-term social determinants. Using a systematic review methodology, we conducted an initial assessment of intervention evaluations targeting 6 adulthood preparation subject (APS) areas to assess the quality and character of the evidence base. The review is specific to evaluated interventions that address at least 1 of the 6 APS areas: healthy relationships, adolescent development, financial literacy, parent-child communication, educational and career success, and healthy life skills. The inclusion criteria were as follows: (1) published in English in an independent, peer-reviewed journal; (2) conducted in developed, English-speaking countries; (3) implemented an intervention that addressed at least 1 of the 6 APS areas, delivered in an in-person setting; (4) included youths at the 5th- through 12th-grade levels or aged 10 to 18 years at some point during intervention implementation; (5) included an evaluation component with a comparison group and baseline and follow-up measures; (6) included behavioral measures as outcomes; and (7) reported statistical significance levels for the behavioral outcome measures. We developed an abstraction form to capture details from each article, including key details of the intervention, such as services, implementer characteristics, and timing; adulthood preparation foci; evaluation design, methods, and key behavioral measures; and results, including key statistically significant results for behavior-based outcome measures. We assessed study quality by using several key factors, including randomization, baseline equivalence of treatment and control groups, attrition, and confounding factors. We characterized the quality of evidence as high, moderate, or low on the basis of the described design and execution of the research. Our assessment included only information stated explicitly in the manuscript. A total of 36 independent intervention evaluations met the criteria for inclusion. Of these, 27 (75%) included significant findings for behavioral outcomes related to adulthood preparation. Quality was mixed across studies. Of the 36 studies reviewed, 27 used a randomized controlled design (15 group randomization, 12 individual randomization), whereas the others used observational pre-post designs. Ten studies used mixed-methods approaches. Most (n = 32) studies used self-report questionnaires at baseline with a follow-up questionnaire, and 14 studies included multiple follow-up points. Of the studies reviewed, 7 studies received a high-quality rating, indicating no significant issues identified within our quality criteria. We rated 23 studies as moderate quality, indicating methodological challenges within 1 of the quality criteria categories. The most common reasons studies were down-rated were poor baseline equivalency across treatment groups (or no discussion of baseline equivalency) and high levels of attrition. Finally, 6 studies received a low-quality rating because of methodological challenges across multiple quality domains. The studies broadly represented the APS areas. We identified no systematic differences in study quality across the APS areas. Although some of the intervention results indicate behavioral changes that may be linked to adulthood preparation skills, many of the extant findings are derived from moderate- or poor-quality studies. Additional work is needed to build the evidence base by using methodologically rigorous implementation and evaluation designs and execution. Public Health Implications. Interventions designed to help adolescents better prepare for adulthood may have the potential to affect their longer-term social determinants of health and well-being. More theory-driven approaches and rigorously evaluated interventions could strengthen the evidence base and improve the effectiveness of these adulthood preparation interventions.

Our assessment included only information stated explicitly in the manuscript. Main Results. A total of 36 independent intervention evaluations met the criteria for inclusion. Of these, 27 (75%) included significant findings for behavioral outcomes related to adulthood preparation. Quality was mixed across studies. Of the 36 studies reviewed, 27 used a randomized controlled design (15 group randomization, 12 individual randomization), whereas the others used observational pre–post designs. Ten studies used mixed-methods approaches. Most (n = 32) studies used self-report questionnaires at baseline with a follow-up questionnaire, and 14 studies included multiple follow-up points. Of the studies reviewed, 7 studies received a high-quality rating, indicating no significant issues identified within our quality criteria. We rated 23 studies as moderate quality, indicating methodological challenges within 1 of the quality criteria categories. The most common reasons studies were down-rated were poor baseline equivalency across treatment groups (or no discussion of baseline equivalency) and high levels of attrition. Finally, 6 studies received a low-quality rating because of methodological challenges across multiple quality domains. The studies broadly represented the APS areas. We identified no systematic differences in study quality across the APS areas. Author’s Conclusions. Although some of the intervention results indicate behavioral changes that may be linked to adulthood preparation skills, many of the extant findings are derived from moderate- or poor-quality studies. Additional work is needed to build the evidence base by using methodologically rigorous implementation and evaluation designs and execution. Public Health Implications. Interventions designed to help adolescents better prepare for adulthood may have the potential to affect their longer-term social determinants of health and well-being. More theory-driven approaches and rigorously evaluated interventions could strengthen the evidence base and improve the effectiveness of these adulthood preparation interventions. PMID:29443561

Din Osmun, Laila; Pillai Riddell, Rebecca; Flora, David B

2014-01-01

To examine the predictive relationships of early infant and caregiver variables on expressed pain-related negative affect duration at the 12-month immunization. Infants and their caregivers (N = 255) were followed during immunization appointments over the first year of life. Latent growth curve modeling in a structural equation modeling context was used. Higher levels of initial infant pain reactivity at 2 months and caregiver emotional availability averaged across 2, 4, and 6 months of age were related to larger decreases in the duration of infant negative affect over the first 6 months of life. Longer duration of infant negative affect at 2 months and poorer regulation of infant negative affect over the first 6 months of life predicted longer durations of infant negative affect by 12 months. Infant negative affect at 12 months was a function of both infant factors and the quality of caregiver interactive behaviors (emotional availability) in early infancy.

Negative affect in at-risk youth: Outcome expectancies mediate relations with both regular and electronic cigarette use.

Despite the general trend of declining use of traditional cigarettes among young adults in the United States, alternative high school students continue to smoke cigarettes and electronic cigarettes at rates much higher than do students attending regular high schools. Challenging life circumstances leading to elevated levels of negative affect may account for increased smoking behavior in this population. Further, a belief in the negative affect-reducing qualities of nicotine may mediate this effect. The current study tested the hypothesis that negative reinforcing outcome expectancies mediate the relationship between negative affect on smoking susceptibility in nonusers, smoking frequency in users, and smoking experimentation in the overall sample. Results support the hypothesis that negative affect in alternative high school students is correlated with smoking experimentation, smoking willingness, and smoking frequency and that the relationship between negative affect and smoking behavior outcomes is mediated by negative reinforcing outcome expectancies (i.e., beliefs in the negative affect-reducing effects of smoking). This finding was supported for both cigarettes and electronic cigarettes and coincides with a rapid increase in the number of high school students nationally who have experimented with electronic cigarettes. Future antismoking initiatives directed at at-risk youth should consider integrating healthier negative affect reduction techniques to counter the use of nicotine products.

DNA methylation plays important roles in regulating many physiological behaviors; however, few studies were focused on the changes of DNA methylation during oocyte aging. Early studies showed that some imprinted genes' DNA methylation had been changed in aged mouse oocytes. In this study, we used porcine oocytes to test the hypothesis that oocyte aging would alter DNA methylation pattern of genes and disturb their expression in age oocytes, which affected the developmental potential of oocytes. We compared several different types of genes and found that the expression and DNA methylation of Neuronatin (NNAT) were disturbed in aged oocytes significantly. Additional experiments demonstrated that glucose transport was impaired in aged oocytes and injection of NNAT antibody into fresh oocytes led to the same effects on glucose transport. These results suggest that the expression of NNAT was declined by elevating DNA methylation, which affected oocyte quality by decreasing the ability of glucose transport in aged oocytes.

Physical Activity, Mind Wandering, Affect, and Sleep: An Ecological Momentary Assessment

2016-01-01

Background A considerable portion of daily thought is spent in mind wandering. This behavior has been related to positive (eg, future planning, problem solving) and negative (eg, unhappiness, impaired cognitive performance) outcomes. Objective Based on previous research suggesting future-oriented (ie, prospective) mind wandering may support autobiographical planning and self-regulation, this study examined associations between hourly mind wandering and moderate-to-vigorous physical activity (MVPA), and the impact of affect and daily sleep on these relations. Methods College-aged adults (N=33) participated in a mobile phone-delivered ecological momentary assessment study for 1 week. Sixteen hourly prompts assessing mind wandering and affect were delivered daily via participants’ mobile phones. Perceived sleep quality and duration was assessed during the first prompt each day, and participants wore an ActiGraph accelerometer during waking hours throughout the study week. Results Study findings suggest present-moment mind wandering was positively associated with future MVPA (P=.03), and this relationship was moderated by affective state (P=.04). Moreover, excessive sleep the previous evening was related to less MVPA across the following day (P=.007). Further, mind wandering was positively related to activity only among those who did not oversleep (P=.007). Conclusions Together, these results have implications for multiple health behavior interventions targeting physical activity, affect, and sleep. Researchers may also build on this work by studying these relationships in the context of other important behaviors and psychosocial factors (eg, tobacco use, depression, loneliness). PMID:27580673

Among older children and adolescents, keeping secrets from parents is consistently associated with lower levels of psychological well-being. Further, concealing one's thoughts and emotions has been associated with poor physical health outcomes in adults. However, it remains an open question whether secret-keeping is associated with poorer health and health-related behaviors (such as sleep) among youth and, if those hypothesized links exist, what the psychological mechanisms might be. We investigated the associations among youth secrecy towards parents, daily asthma symptoms and daily sleep behaviors in a sample of low-income youth with asthma aged 10-17 and tested negative affect as a possible mediator of these associations. One hundred and seventy two youths reported the extent to which they kept secrets towards parents over a period of four days. Asthma symptoms, nighttime awakenings, sleep onset latency, and subjective sleep quality were assessed with daily diaries completed by youths. More frequent secret-keeping was associated with more severe asthma symptoms, lower ratings of sleep quality and greater number of nighttime awakenings. Secrecy was also associated with increased negative affect, which accounted for the associations between secrecy and number of awakenings and daytime asthma symptoms. These findings remained significant after controlling for youth age and other relevant demographic factors. Our findings suggest that secrecy towards parents can have consequential health outcomes for youth with asthma and point to the importance of investigating affective processes as mediators of the influence of secret-keeping on youth health.

Although a flurry of meta-analyses summarized the justice literature at the turn of the millennium, interest in the topic has surged in the decade since. In particular, the past decade has witnessed the rise of social exchange theory as the dominant lens for examining reactions to justice, and the emergence of affect as a complementary lens for understanding such reactions. The purpose of this meta-analytic review was to test direct, mediating, and moderating hypotheses that were inspired by those 2 perspectives, to gauge their adequacy as theoretical guides for justice research. Drawing on a review of 493 independent samples, our findings revealed a number of insights that were not included in prior meta-analyses. With respect to social exchange theory, our results revealed that the significant relationships between justice and both task performance and citizenship behavior were mediated by indicators of social exchange quality (trust, organizational commitment, perceived organizational support, and leader-member exchange), though such mediation was not apparent for counterproductive behavior. The strength of those relationships did not vary according to whether the focus of the justice matched the target of the performance behavior, contrary to popular assumptions in the literature, or according to whether justice was referenced to a specific event or a more general entity. With respect to affect, our results showed that justice-performance relationships were mediated by positive and negative affect, with the relevant affect dimension varying across justice and performance variables. Our discussion of these findings focuses on the merit in integrating the social exchange and affect lenses in future research.

Rett syndrome (RTT) is a neurodevelopmental disorder associated with mutations in the X-linked gene encoding methyl-CpG-binding protein 2 (MeCP2) and consequent dysregulation of brain maturation. Patients suffer from a range of debilitating physical symptoms, however, behavioral and emotional symptoms also severely affect their quality of life. Here, we present previously unreported and clinically relevant affective dysfunction in the female heterozygous Mecp2(tm1Tam) mouse model of RTT (129sv and C57BL6 mixed background). The affective dysfunction and aberrant anxiety-related behavior of the Mecp2(+/-) mice were found to be reversible with environmental enrichment (EE) from 4 weeks of age. The effect of exercise alone (via wheel running) was also explored, providing the first evidence that increased voluntary physical activity in an animal model of RTT is beneficial for some phenotypes. Mecp2(+/-) mutants displayed elevated corticosterone despite decreased Crh expression, demonstrating hypothalamic-pituitary-adrenal axis dysregulation. EE of Mecp2(+/-) mice normalized basal serum corticosterone and hippocampal BDNF protein levels. The enrichment-induced rescue appears independent of the transcriptional regulation of the MeCP2 targets Bdnf exon 4 and Crh. These findings provide new insight into the neurodevelopmental role of MeCP2 and pathogenesis of RTT, in particular the affective dysfunction. The positive outcomes of environmental stimulation and physical exercise have implications for the development of therapies targeting the affective symptoms, as well as behavioral and cognitive dimensions, of this devastating neurodevelopmental disorder. © 2015 Wiley Periodicals, Inc.

Sexual behavior usually begins in adolescence, and is mediated by biological, personality and socio-cultural variables which can affect the expression of preventive and risky sexual performance, as well as sex and age differences. To determine sex differences in the age of sexual initiation, the use of protective methods and mate selectivity in young men and women, as well as preventive practices according to age, and the prevalence of partner aggression. Participants were 484 university students from public and private institutions, aged 22 ± 3 years (59% women) assessed using a diversity of self-report measures of personality traits, romantic relationship quality, sexual role, attachment type, socio-sexual openness, and self-esteem; they also answered questions regarding sexual behavior, and violence. Differences in age of sexual initiation, risky sexual behavior, and socio-sexual openness were observed between men and women. Aggression prevalence in romantic relationships also varied according to sex and age. Similarities and differences in patterns of behavior and personality variables were observed in relationship quality, sexual role, kindness, and responsibility in males and females. The findings present consistencies with the international evidence and differences that may be due to context specificities, providing also an empirical referent to consider in health planning.

Sodium dodecyl benzene sulfonate (SDBS) is a kind of widely used anionic surfactant and its discharge may pose potential risk to the receiving aquatic ecosystem. The aim of our study is to investigate the toxic effect of SDBS on fish swimming behavior quantitatively, followed by examination whether there are significant differences of swimming behavior among applied fish species (i.e. zebra fish (Danio rerio), Japanese medaka (Oryzias latipes) and red carp (Cyprinus carpio)). The swimming speed and vertical position were analyzed after the fish exposed to SDBS aiming to reflect the toxicity of SDBS on fish. Our results showed that the swimming behavior of three fishes was significantly affected by SDBS, although there were slight differences of swimming pattern changes among three fish species when they exposed to the same concentration of SDBS. It could be seen that red carp, one of the native fish species in China, can be used as a model fish to reflect the water quality changes as well as zebra fish and Japanese medaka which are commonly used as model fishes. Our study also illustrated that the swimming behavior monitoring may have a good application prospect in pre-warning of water quality. Copyright © 2015 Elsevier B.V. All rights reserved.

Parental Work Schedules and Adolescent Risky Behaviors

Han, Wen-Jui; Miller, Daniel P.; Waldfogel, Jane

2013-01-01

Using a large contemporary data set, the National Longitudinal Survey of Youth-Child Supplement (NLSY-CS), this paper examines the effects of parental work schedules on adolescent risky behaviors at age 13 or 14 and the mechanisms that might explain them. Structural equation modeling suggests mothers who worked more often at night spent significantly less time with children and had lower quality home environments, and these mediators were significantly linked to adolescent risky behaviors. Similar effects were not found for evening work schedules, while other types of maternal and paternal nonstandard work schedules were linked to higher parental knowledge of children’s whereabouts, which led to lower levels of adolescent risky behaviors. Subgroup analyses revealed that males, those in families with low incomes, and those whose mothers never worked at professional jobs may particularly be affected by mothers working at nights, due to spending less time together, having a lower degree of maternal closeness, and experiencing lower quality home environments. In addition, the effects of maternal night shifts were particularly pronounced if children were in the preschool or middle-childhood years when their mothers worked those schedules. Implications and avenues for future research are discussed. PMID:20822236

Professionalism is characterized by the degree of dedication displayed by individuals regarding the values and behavioral attributes of a specific career identity. Professionalism indicates attitudes that represent high levels of identification with and commitment to a specific profession. In the process of the professional development of nursing, various factors affect these obstacles which may impede the professional development of nurses and their professional behaviors. This study was carried out with the aim of determining the professional behavior of nurses in a hospital in Turkey. In this descriptive exploratory study a total of 89 nurses working in a public hospital in northwestern of Turkey were participated. Data were collected using a demographic questionnaire and Behavioral Inventory Form for Professionalism in Nursing (BIPN). The result showed that mean scores on the BIPN were 5.07 (3.47). The areas with the highest levels of professional behavior were competence and continuing education 1.88 (0.34). The professionalism levels for nurses were the lowest in the areas of autonomy 0.06 (0.34), publication 0.10 (0.25), and research 0.25 (0.60). There was a statistically significant difference between the total BIPN scores and the education levels of the nurses and the working of nurses. The professional behavior of nurses is at a low level. Since the arrangement of the nurses' working conditions affects their professional behaviors; therefore, development in the field of professional behaviors in nursing must be assessed and supported to increase the quality of patient care.

Objective Our objectives were to describe a sample of truck drivers, identify clusters of drivers with similar patterns in behaviors affecting energy balance (sleep, diet, and exercise), and test for cluster differences in health and psychosocial factors. Methods Participants’ (n=452, BMI M=37.2, 86.4% male) self-reported behaviors were dichotomized prior to hierarchical cluster analysis, which identified groups with similar behavior co-variation. Cluster differences were tested with generalized estimating equations. Results Five behavioral clusters were identified that differed significantly in age, smoking status, diabetes prevalence, lost work days, stress, and social support, but not in BMI. Cluster 2, characterized by the best sleep quality, had significantly lower lost workdays and stress than other clusters. Conclusions Weight management interventions for drivers should explicitly address sleep, and may be maximally effective after establishing socially supportive work environments that reduce stress exposures.

Research over the past 20 years suggests that the quality of the parent-adolescent relationship significantly affects the development of risk behaviors in adolescent health. The purpose of this paper is to present a review of studies published between 1996-2007 that address specific relationships between parenting styles and six priority adolescent risk behaviors. The review supports the substantial influence of parenting style on adolescent development. Adolescents raised in authoritative households consistently demonstrate higher protective and fewer risk behaviors than adolescents from non-authoritative families. There is also considerable evidence to show that parenting styles and behaviors related to warmth, communication and disciplinary practices predict important mediators, including academic achievement and psychosocial adjustment. Careful examination of parenting style patterns in diverse populations, particularly with respect to physical activity and unintentional injury, will be a critical next step in the development of efficacious, culturally tailored adolescent health promotion interventions.

The effects of breakfast on behavior and academic performance in children and adolescents

Breakfast consumption is associated with positive outcomes for diet quality, micronutrient intake, weight status and lifestyle factors. Breakfast has been suggested to positively affect learning in children in terms of behavior, cognitive, and school performance. However, these assertions are largely based on evidence which demonstrates acute effects of breakfast on cognitive performance. Less research which examines the effects of breakfast on the ecologically valid outcomes of academic performance or in-class behavior is available. The literature was searched for articles published between 1950–2013 indexed in Ovid MEDLINE, Pubmed, Web of Science, the Cochrane Library, EMBASE databases, and PsychINFO. Thirty-six articles examining the effects of breakfast on in-class behavior and academic performance in children and adolescents were included. The effects of breakfast in different populations were considered, including undernourished or well-nourished children and adolescents from differing socio-economic status (SES) backgrounds. The habitual and acute effects of breakfast and the effects of school breakfast programs (SBPs) were considered. The evidence indicated a mainly positive effect of breakfast on on-task behavior in the classroom. There was suggestive evidence that habitual breakfast (frequency and quality) and SBPs have a positive effect on children's academic performance with clearest effects on mathematic and arithmetic grades in undernourished children. Increased frequency of habitual breakfast was consistently positively associated with academic performance. Some evidence suggested that quality of habitual breakfast, in terms of providing a greater variety of food groups and adequate energy, was positively related to school performance. However, these associations can be attributed, in part, to confounders such as SES and to methodological weaknesses such as the subjective nature of the observations of behavior in class.

Little is known about how factors within the general family environment are associated with weight and related behaviors among adolescents/young adults. We studied 3768 females and 2614 males, 14-24 years old in 2011, participating in the Growing Up Today Study 2. We used generalized mixed models to examine cross-sectional associations of family functioning and quality of mother- and father-adolescent relationship with adolescent/young adult weight status, disordered eating, intake of fast food and sugar-sweetened beverages, screen time, physical activity, and sleep duration. In all models, we included participant's age and family structure. Eighty percent of participants reported high family functioning and 60% and 50% of participants reported high-quality mother and father relationship, respectively. Among both males and females, high family functioning was associated with lower odds of disordered eating (adjusted odds ratio [AOR] females = 0.53; 95% Confidence Interval [CI] = 0.45-0.63; AOR males = 0.48; CI = 0.39-0.60), insufficient physical activity, i.e., less than 1 h/day, (AOR females = 0.74; CI = 0.61-0.89; AOR males = 0.73; CI = 0.58-0.92), and insufficient sleep, i.e., less than 7 h/day, (AOR females = 0.56; CI = 0.45-0.68; AOR males = 0.65; CI 0.5-0.85). High family functioning was also associated with lower odds of being overweight/obese (AOR = 0.73; CI = 0.60-0.88) and eating fast food one or more times/week (AOR = 0.74; CI = 0.61-0.89) among females only. Among females, high-quality mother and father relationship were both associated with lower odds of being overweight/obese and disordered eating, eating fast food, and insufficient sleep and the magnitude of associations were similar for mother and father relationship quality (AOR range 0.61-0.84). Among males, high-quality mother and father relationship were both associated with lower odds of disordered eating, insufficient physical activity and insufficient sleep, but only father relationship quality was associated with lower odds of overweight/obesity. Adolescents/young adults reporting high family functioning and more positive relationships with their parents reported better weight-related behaviors. For weight status, females appear to be affected equally by the quality of their relationship with both parents, whereas males may be more affected by their relationship with fathers.

Cultural competence and medical education: many names, many perspectives, one goal.

Betancourt, Joseph R

2006-06-01

Two contemporary reports from the Institute of Medicine--Crossing the Quality Chasm and Unequal Treatment--highlighted the importance of patient-centered care and cultural competence training as a means of improving the quality of health care for all and eliminating racial/ethnic disparities in health care. Previous efforts in cultural competence have aimed to teach about the attitudes, values, beliefs, and behavior of certain groups. A more effective approach is to learn a practical framework to guide inquiry with individual patients about how social, cultural, or economic factors influence their health values, beliefs, and behaviors. Rather than learning about individual cultures and their characteristics, this approach focuses on the issues that arise most commonly due to cultural differences, and how they may affect a physician's interaction with any patient. At the end of the day, physicians need a practical set of tools and skills that will enable them to provide quality care to patients everywhere, from anywhere, with whatever differences in background that may exist, in what is likely to be a brief clinical encounter. Call it what you will, the field of cultural competence aims quite simply to assure that health care providers are prepared to provide quality care to diverse populations.

This study forms part of a broader project aimed at understanding the role of fibers from different sources in high-fat, high-sugar biscuits and at selecting the best fibers for biscuit quality. The main purpose of this work was to understand the rheological and structural properties involved in fiber-enriched biscuit dough. High-amylose corn starch (RSII), chemically modified starch (RSIV), oat fiber (OF) and inulin (IN) were used at two different levels of incorporation (6 and 12 g) in dough formulation. The influence of fiber on the properties of biscuit dough was studied via dynamic rheological tests, confocal microscopy and spreading behavior. Biscuit quality was assessed by width/thickness factor, texture and surface characteristics, total dietary fiber and sensory evaluation. Main results indicated that IN incorporation increased the capacity of dough spreading during baking and thus improved biscuit quality. OF reduced dough spreading during baking and strongly increased its resistance to deformation. RSII and RSIV slightly affected the quality of the biscuits. Sensory evaluation revealed that the panel liked IN-incorporated biscuits as much as control biscuits. The increase in total dietary fiber modified dough behavior and biscuit properties, and the extent of these effects depended on the type of fiber incorporated. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

Water quality can be evaluated using biomarkers such as tissular enzymatic activities of endemic species. Measurement of molluscs bivalves activity at high frequency (e.g., valvometry) during a long time period is another way to record the animal behavior and to evaluate perturbations of the water quality in real time. As the pollution affects the activity of oysters, we consider the valves opening and closing velocities to monitor the water quality assessment. We propose to model the huge volume of velocity data collected in the framework of valvometry using a new nonparametric extreme values statistical model. The objective is to estimate the tail probabilities and the extreme quantiles of the distribution of valve closing velocity. The tail of the distribution function of valve closing velocity is modeled by a Pareto distribution with parameter t,τ , beyond a threshold τ according to the time t of the experiment. Our modeling approach reveals the dependence between the specific activity of two enzymatic biomarkers (Glutathione-S-transferase and acetylcholinesterase) and the continuous recording of oyster valve velocity, proving the suitability of this tool for water quality assessment. Thus, valvometry allows in real-time in situ analysis of the bivalves behavior and appears as an effective early warning tool in ecological risk assessment and marine environment monitoring.

A principle concern in estimation is the presence of market-level unobserved heterogeneity that may be correlated with changes in single male quality, measured as earning potential. To address this concern, we employ a differencing strategy that normalizes the exercise behaviors of single women to those of their married counterparts. Our main results suggest that when potential mate quality in a marriage market decreases, single black women invest less in healthy body weight. For example, we find that a 10 percentage point increase in the proportion of low quality single black males leads to a 5-10% decrease in vigorous exercise taken by single black females. Results for single white women are qualitatively similar, but not consistent across specifications. These results highlight the relationship between male and female human capital acquisition that is driven by participation in the marriage market. Our results suggest that programs designed to improve the economic prospects of single males may yield positive externalities in the form of improved health behaviors, such as more exercise, particularly for single black females.

In young children with type 1 diabetes mellitus (T1DM) parents have full responsibility for the diabetes-management of their child (e.g. blood glucose monitoring, and administering insulin). Behavioral tasks in childhood, such as developing autonomy, and oppositional behavior (e.g. refusing food) may interfere with the diabetes-management to achieve an optimal blood glucose control. Furthermore, higher blood glucose levels are related to more behavioral problems. So parents might need to negotiate with their child on the diabetes-management to avoid this direct negative effect. This interference, the negotiations, and the parent's responsibility for diabetes may negatively affect the quality of parent-child interaction. Nevertheless, there is little knowledge about the quality of interaction between parents and young children with T1DM, and the possible impact this may have on glycemic control and psychosocial functioning of the child. While widely used global parent-child interaction observational methods are available, there is a need for an observational tool specifically tailored to the interaction patterns of parents and children with T1DM. The main aim of this study is to construct a disease-specific observational method to assess diabetes-specific parent-child interaction. Additional aim is to explore whether the quality of parent-child interactions is associated with the glycemic control, and psychosocial functioning (resilience, behavioral problems, and quality of life). First, we will examine which situations are most suitable for observing diabetes-specific interactions. Then, these situations will be video-taped in a pilot study (N = 15). Observed behaviors are described into rating scales, with each scale describing characteristics of parent-child interactional behaviors. Next, we apply the observational tool on a larger scale for further evaluation of the instrument (N = 120). The parents are asked twice (with two years in between) to fill out questionnaires about psychosocial functioning of their child with T1DM. Furthermore, glycemic control (HbA1c) will be obtained from their medical records. A disease-specific observational tool will enable the detailed assessment of the quality of diabetes-specific parent-child interactions. The availability of such a tool will facilitate future (intervention) studies that will yield more knowledge about impact of parent-child interactions on psychosocial functioning, and glycemic control of children with T1DM.

The consequences of alternating diet on performance and food preferences of a specialist leaf beetle.

PubMed

Tremmel, Martin; Müller, Caroline

The food quality of a given host plant tissue will influence the performance and may also affect the preference behavior of herbivorous animals. As nutrient contents and defense metabolite concentrations can vary significantly between different parts of a plant and change over time, herbivores are potentially confronted with diet differing in quality even when feeding on a single plant individual. Here we investigated to what extent feeding exclusively either on young or old, mature leaves of Brassica rapa or on a mixed diet of young and old leaves offered in alternating order affects the larval performance, food consumption, and the host preference behavior of adult mustard leaf beetles, Phaedon cochleariae. Analyzing different leaf quality traits, we found lower water contents, no changes in C:N ratio but more than threefold higher glucosinolate concentrations in young compared to old leaves. Individuals reared on mixed diet performed as well as animals reared on young leaves. Thus, compared to animals feeding exclusively on highly nutritious young leaves, diet-mixing individuals may balance the lower nutrient intake by a dilution of adverse secondary metabolites. Alternatively, they may integrate over the variation in their food, using a previously assimilated resource for growth at times of scarcity. Animals reared on old leaves grew less and had a prolonged larval developmental time, although they showed increased consumption indicating compensatory feeding. Additionally, we found that experience with a certain diet affected the preference behavior. Whereas individuals reared exclusively on young leaves preferred young over old leaves for feeding and oviposition, we did not find any preferences by animals reared exclusively on old leaves or by females reared on alternating diet. Thus, in contrast to positive feedbacks for animals reared on young leaves, an integrative growth of diet-mixing individuals potentially leads to a lack of feedback during development. Taken together, our results suggest that different diet regimes can lead to comparable performance of mustard leaf beetles but experienced feedbacks may differ and thus convey distinct diet preferences.

Background. Documented trends in health-related risk behaviors among US adolescents have remained high over time. Studies indicate relationships among mutual friends are a major influence on adolescents’ risky behaviors. Social Network Analysis (SNA) can help understand friendship ties affecting individual adolescents’ engagement in these behaviors. Moreover, a systematic literature review can synthesize findings from a range of studies using SNA, as well as assess these studies’ methodological quality. Review findings also can help health educators and promoters develop more effective programs. Objective. This review systematically examined studies of the influence of friendship networks on adolescents’ risk behaviors, which utilized SNA and the Add Health data (a nationally representative sample). Methods. We employed the Matrix Method to synthesize and evaluate 15 published studies that met our inclusion and exclusion criteria, retrieved from the Add Health website and 3 major databases (Medline, Eric, and PsycINFO). Moreover, we assigned each study a methodological quality score (MQS). Results. In all studies, friendship networks among adolescents promoted their risky behaviors, including drinking alcohol, smoking, sexual intercourse, and marijuana use. The average MQS was 4.6, an indicator of methodological rigor (scale: 1–9). Conclusion. Better understanding of risky behaviors influenced by friends can be useful for health educators and promoters, as programs targeting friendships might be more effective. Additionally, the overall MQ of these reviewed studies was good, as average scores fell above the scale’s mid-point. PMID:26157622

Eveningness has been found to negatively affect adolescents' sleep and daytime functioning. Furthermore, eveningness is associated with greater impulsivity than morningness. Externalizing behavior could be chronotype-related, implying that the alteration of the circadian rhythm itself is connected to aspects of emotion and emotion regulation. The present study investigated chronotype-related differences in emotional and behavioral problems, especially aggression and antisocial behavior in children and adolescents. We conducted a comprehensive search via web of knowledge (MEDLINE, web of science), EBSCO, Ovid, PubMed, Google Scholar and PsycINDEX using the keywords: chronotype, chronobiology, morningness, eveningness, owls and larks as well as diurnal preference to fully capture every aspect of chronotype. For aggression we used the search terms: aggression, anger, hostility, violence, anti-social behavior, conduct disorder, oppositional defiant disorder, delinquency, social adjustment and externalizing behavior. N = 13 studies were included concerning chronotype, childhood, adolescence and antisocial behavior. Results showed that children and adolescents being E-types were more affected by daytime impairments. Additionally, behavioral and emotional problems as aggression or antisocial behavior were more pronounced in E- than in M-types. Our findings support an association of eveningness and the impact of aggression on children and adolescents. Longitudinal investigations should be conducted in order to insure causality of the effects in question. In addition, the elevated vulnerability toward aggression in evening types demonstrates the need for prevention and intervention programs that educate youths in proper sleep hygiene and evoke an awareness of the consequences of a habitually diminished sleep quality.

The use of storytelling in health promotion has grown over the past 2 decades, showing promise for moving people to initiate healthy behavior change. Given the increasingly prevalent role of storytelling in health promotion research and the need to more clearly identify what storytelling elements and mediators may better predict behavior change, there is a need to develop measures to specifically assess these factors in a cultural community context. The purpose of this study is to develop and preliminarily validate a narrative quality assessment tool for measuring elements of storytelling that are predicted to affect attitude and behavior change (i.e., narrative characteristics, identification, and transportation) within a cultural community setting using a culture-centric model. Reliability and validity of these scales were assessed with repeated administrations among 74 Latino men and women with a mean age of 39.6 years (SD = 11.47 years). The confirmatory factor analysis in addition to internal consistency tests revealed preliminary evidence for reliability and validity of the narrative characteristics, identification, and transportation scales. Cronbach's alpha ranged from .92 to .94. Items revealed adequate factor loadings (.85-.98) and good model fit. The new scales provide the first step in moving the assessment of narrative quality into a culturally relevant context for evaluation of story use in health promotion. The results present valuable information for nurse researchers to guide the development and testing of culturally grounded storytelling interventions' potential to predict attitude and behavior change for patients.

Does direct-to-consumer advertising affect patients' choice of pain medications?

PubMed

Liu, Yifei; Doucette, William R

2008-04-01

In the United States, direct-to-consumer advertising (DTCA) has grown rapidly to promote prescription medications, including analgesics. Few studies in the literature directly examine the association between DTCA and patients' choice of pain medications. This article discusses how DTCA affects such choice from a behavioral perspective, because DTCA-prompted behaviors are important indicators of DTCA's influence. After DTCA exposure, patients may request prescriptions, seek further medication information, and ask about advertised conditions. Patients who suffer from pain may seek more communication with their health care providers because they are cautious about the information quality of DTCA, mainly because of the recall of rofecoxib (Vioxx; Merck, Whitehouse Station, NJ). However, the availability and DTCA of over-the-counter analgesics complicate their treatment choice. Patients could use DTCA as a tool to launch health communication and make an informed treatment choice with the guidance of their health care providers.

Inulin-enriched dairy desserts: physicochemical and sensory aspects.

2009-09-01

The aim of this work was to study how adding inulin of different average chain lengths (long-chain, native, and short-chain inulin) at a concentration of 7.5% (wt/wt) would affect the physicochemical and sensory characteristics of starch-based dairy desserts formulated with either skim or whole milk. The results have shown that the effect of adding 7.5% inulin of different average chain length can give rise to products with different rheological behavior and different sensory characteristics. The skim milk sample with long-chain inulin and the whole milk sample without inulin showed similar flow behavior. Both samples were perceived to have the same creaminess and consistency intensity, but addition of long-chain inulin increased roughness intensity and, consequently, the sensory quality could be negatively affected. The information obtained may be of great interest in designing new products with nutritional and sensory characteristics that meet consumer demands.

Mild cognitive impairment affects motor control and skill learning.

Mild cognitive impairment (MCI) is a transitional phase between normal cognitive aging and dementia. As the world population is aging rapidly, more MCI patients will be identified, posing significant problems to society. Normal aging is associated with cognitive and motor decline, and MCI brings additional impairments. Compared to healthy older adults, MCI patients show poorer motor control in a variety of tasks. Efficient motor control and skill learning are essential for occupational and leisure purposes; degradation of motor behaviors in MCI patients often adversely affects their health and quality of life. In this article, we first define MCI and describe its pathology and neural correlates. After this, we review cognitive changes and motor control and skill learning in normal aging. This section is followed by a discussion of MCI-related degradation of motor behaviors. Finally, we propose that multicomponent interventions targeting both cognitive and motor domains can improve MCI patients' motor functions. Future research directions are also raised.

Hommos was treated with gamma radiation and stored at 4 °C for a period of five weeks with the aim of extending its shelf life under refrigeration. Viscosity and colour of the product were evaluated instrumentally at 5-day intervals, and its sensory quality was evaluated by a taste panel at the beginning and end of the storage period. The results indicate that irradiation combined with storage caused reduction of the ΔE*ab, a*, b* and L* colour values, but have no such an effect on the apparent viscosity, flow behavior index (n) or consistency coefficient (k) of the product which exhibited a non-Newtonian, pseudoplastic behavior. Neither irradiation dose nor storage time affected the overall acceptability, flavor, smoothness, mouth- feel and colour of the product when evaluated by a taste panel. The product irradiated with 1.5 or 2.5 kGy can be stored at 4 °C for 35 days and still maintain its sensory and physical qualities indicating that the shelf life of this product, like other irradiated foods, can be extended by this combined treatment.

Prey availability affects territory size, but not territorial display behavior, in green anole lizards

The availability of food resources can affect the size and shape of territories, as well as the behaviors used to defend territories, in a variety of animal taxa. However, individuals within a population may respond differently to variation in food availability if the benefits of territoriality vary among those individuals. For example, benefits to territoriality may differ for animals of differing sizes, because larger individuals may require greater territory size to acquire required resources, or territorial behavior may differ between the sexes if males and females defend different resources in their territories. In this study, we tested whether arthropod abundance and biomass were associated with natural variation in territory size and defense in insectivorous green anole lizards, Anolis carolinensis. Our results showed that both male and female lizards had smaller territories in a habitat with greater prey biomass than lizards in habitats with less available prey, but the rates of aggressive behaviors used to defend territories did not differ among these habitats. Further, we did not find a relationship between body size and territory size, and the sexes did not differ in their relationships between food availability and territory size or behavioral defense. Together, these results suggest that differences in food availability influenced male and female territorial strategies similarly, and that territory size may be more strongly associated with variation in food resources than social display behavior. Thus, anole investment in the behavioral defense of a territory may not vary with territory quality.

Background: Hypertension affects the quality of life of patients and their caregivers. The aim of this study was to assess the knowledge and self-care behaviors and health-related quality of life (HRQOL) among hypertensive people. Methods: All people aged 35 years and older with hypertension were invited to participate in this study. Information on self-care behavior for hypertension (H-scale), and health-related quality of life (WHOHRQOL-BRFF) were completed by trained interviewer. Data analysis was done using SPSS 16. Results: The median age of hypertensive patients was 62.5(25th to 75th percentile: 55 to 72 years), the correlation between quality of life and overall self-care scores was not significant(r =-0.048, P =0.520). Physical activity was the only significant predictor for quality of life,showing that the quality of life of hypertensive people increased by 3.371 units per day of being physically active in the cohort study (β =0.223, P<0.01). The only significant predictor of quality of life among the elderly was medication use (β =-0.572, P<0.001). Quality of life of participants decreased 3.456 units per day as a result of medication adherence. Conclusion: No association was observed between self-care and HRQOL total score in hypertensive patients in the study. Among the self-care domains, only medication adherence and physical activity had significant association with social health. There was a reverse association between smoking and HRQOL.

Frontal Lobe Contusion in Mice Chronically Impairs Prefrontal-Dependent Behavior

PubMed Central

Rosi, Susanna

2016-01-01

Traumatic brain injury (TBI) is a major cause of chronic disability in the world. Moderate to severe TBI often results in damage to the frontal lobe region and leads to cognitive, emotional, and social behavioral sequelae that negatively affect quality of life. More specifically, TBI patients often develop persistent deficits in social behavior, anxiety, and executive functions such as attention, mental flexibility, and task switching. These deficits are intrinsically associated with prefrontal cortex (PFC) functionality. Currently, there is a lack of analogous, behaviorally characterized TBI models for investigating frontal lobe injuries despite the prevalence of focal contusions to the frontal lobe in TBI patients. We used the controlled cortical impact (CCI) model in mice to generate a frontal lobe contusion and studied behavioral changes associated with PFC function. We found that unilateral frontal lobe contusion in mice produced long-term impairments to social recognition and reversal learning while having only a minor effect on anxiety and completely sparing rule shifting and hippocampal-dependent behavior.

This report examines young adults' states of mind regarding their early attachment experiences in relation to the observed and perceived quality of their sibling relationships. Sixty sibling pairs (18-25 years of age) were (a) administered the Adult Attachment Interview (George, Kaplan, & Main, 1985), (b) videotaped during a conflict resolution task, and (c) asked to describe the quality of their relationship using the Adult Sibling Relationship Questionnaire (Stocker, Lanthier, & Furman, 1997). As hypothesized, dismissing states of mind were associated with lower levels of positive and negative affect while participants attempted to resolve an area of conflict with a sibling as well as with relatively low levels of reported warmth in the relationship. In contrast-but also in line with predictions-preoccupied states of mind were associated with heightened expression of negative affect toward a brother or sister, and the siblings of highly preoccupied individuals reported more conflict in their relationships. Findings provide further support for the importance of young adults' representations of childhood attachment experiences with respect to the quality of their adult relationships. In addition, this study extends previous findings regarding the significance of dismissing versus preoccupied states of mind by demonstrating that these dimensions are differentially associated with behavioral and self-reported aspects of sibling relationship quality in early adulthood.

Among early adolescents (10–14 years), poor diet quality along with physical inactivity can contribute to an increased risk of obesity and associated biomarkers for chronic disease. Approximately one-third of United States (USA) children in this age group are overweight or obese. Therefore, attention to factors affecting dietary intake as one of the primary contributors to obesity is important. Early adolescents consume foods and beverages during eating occasions that occur with and without parental supervision. Parents may influence eating behaviors of early adolescents during eating occasions when they are present or during independent eating occasions by engaging in practices that affect availability of foods and beverages, and through perceived normative beliefs and expectations for intake. Therefore, the purpose of this article was to describe the influence of parenting practices on eating behaviors in general and when specifically applied to independent eating occasions of early adolescents. This information may be helpful to inform parenting interventions targeting obesity prevention among early adolescents focusing on independent eating occasions. PMID:26506384

Background Given the growing legalization of recreational marijuana use and related increase in its prevalence in the United States, it is important to understand marijuana's appeal. We used a behavioral economic (BE) approach to examine whether the reinforcing properties of marijuana, including “demand” for marijuana, varied as a function of its perceived quality. Methods Using an innovative, Web-based marijuana purchase task (MPT), a sample of 683 young-adult recreational marijuana users made hypothetical purchases of marijuana across three qualities (low, mid and high grade) at nine escalating prices per joint, ranging from $0/free to $20. Results We used nonlinear mixed effects modeling to conduct demand curve analyses, which produced separate demand indices (e.g., Pmax, elasticity) for each grade of marijuana. Consistent with previous research, as the price of marijuana increased, marijuana users reduced their purchasing. Demand also was sensitive to quality, with users willing to pay more for higher quality/grade marijuana. In regression analyses, demand indices accounted for significant variance in typical marijuana use. Conclusions This study illustrates the value of applying BE theory to young adult marijuana use. It extends past research by examining how perceived quality affects demand for marijuana and provides support for the validity of a Web-based MPT to examine the appeal of marijuana. Our results have implications for policies to regulate marijuana use, including taxation based on the quality of different marijuana products. PMID:27951424

2011-01-01

Approximately two thirds of cancer patients at advanced stages of the disease suffer from anorexia. Defined as the loss of the desire to eat, anorexia lower the energy intake which further exacerbates a progressive deterioration of the patient nutritional status. Malnutrition has a large impact on morbidity and mortality affecting the quality of life. Cancer anorexia etiology is multifactorial including complex interactions among the tumor, host metabolism and antineoplastic treatment. New related theories include peripheral and brain mechanisms affecting hypothalamic pathways; inducing behavioral and metabolic failure of responses to energy balance. The aim of this review is to describe actual concepts involved in the pathogenesis of cancer anorexia with special interest in brain mechanisms. Anorexia and reduced food intake are important issues in the management of cancer patients, more knowledge about pathogenic mechanism is needed to improve therapeutic options, prognosis and quality of life in cancer patients.

Communicating prognosis with parents of critically ill infants: direct observation of clinician behaviors.

2017-11-01

Delivering prognostic information to families requires clinicians to forecast an infant's illness course and future. We lack robust empirical data about how prognosis is shared and how that affects clinician-family concordance regarding infant outcomes. Prospective audiorecording of neonatal intensive care unit family conferences, immediately followed by parent/clinician surveys. Existing qualitative analysis frameworks were applied. We analyzed 19 conferences. Most prognostic discussion targeted predicted infant functional needs, for example, medications or feeding. There was little discussion of how infant prognosis would affect infant/family quality of life. Prognostic framing was typically optimistic. Most parents left the conference believing their infant's prognosis to be more optimistic than did clinicians. Clinician approach to prognostic disclosure in these audiotaped family conferences tended to be broad and optimistic, without detail regarding implications of infant health for infant/family quality of life. Families and clinicians left these conversations with little consensus about infant prognosis.

Quality of life was assessed in 108 epileptic children (6-15 years) using a hindi translation of Quality of Life in Children with Epilepsy (QOLCE) questionnaire. The questionnaire consist of 76 items with 16 subscales covering five domains of life: physical function, social function, cognition, emotional and behavioral well being. Overall score was 62.62±21.32. Chronbachs-a for all 13 multi-item subscales was above 0.70, indicating good internal consistency and reliability. Pearson correlation revealed good construct validity. Overall quality of life was affected by age, type of epilepsy, seizure frequency and maternal education (P<0.05). Energy levels, language and attention (P<0.05) were better in older children whereas younger children had better self esteem and lower levels of anxiety. Seizure frequency compromised all fields except stigma, attention, and energy levels (P>0.05).

Probiotics Improve Inflammation-Associated Sickness Behavior by Altering Communication between the Peripheral Immune System and the Brain.

Patients with systemic inflammatory diseases (e.g., rheumatoid arthritis, inflammatory bowel disease, chronic liver disease) commonly develop debilitating symptoms (i.e., sickness behaviors) that arise from changes in brain function. The microbiota-gut-brain axis alters brain function and probiotic ingestion can influence behavior. However, how probiotics do this remains unclear. We have previously described a novel periphery-to-brain communication pathway in the setting of peripheral organ inflammation whereby monocytes are recruited to the brain in response to systemic TNF-α signaling, leading to microglial activation and subsequently driving sickness behavior development. Therefore, we investigated whether probiotic ingestion (i.e., probiotic mixture VSL#3) alters this periphery-to-brain communication pathway, thereby reducing subsequent sickness behavior development. Using a well characterized mouse model of liver inflammation, we now show that probiotic (VSL#3) treatment attenuates sickness behavior development in mice with liver inflammation without affecting disease severity, gut microbiota composition, or gut permeability. Attenuation of sickness behavior development was associated with reductions in microglial activation and cerebral monocyte infiltration. These events were paralleled by changes in markers of systemic immune activation, including decreased circulating TNF-α levels. Our observations highlight a novel pathway through which probiotics mediate cerebral changes and alter behavior. These findings allow for the potential development of novel therapeutic interventions targeted at the gut microbiome to treat inflammation-associated sickness behaviors in patients with systemic inflammatory diseases. This research shows that probiotics, when eaten, can improve the abnormal behaviors (including social withdrawal and immobility) that are commonly associated with inflammation. Probiotics are able to cause this effect within the body by changing how the immune system signals the brain to alter brain function. These findings broaden our understanding of how probiotics may beneficially affect brain function in the context of inflammation occurring within the body and may open potential new therapeutic alternatives for the treatment of these alterations in behavior that can greatly affect patient quality of life.

Work attitudes have been associated with work productivity. In health care, poor work attitudes have been linked to poor performance, decreased patient safety, and quality care. Hence, the importance, ascribed in the literature, of work that clearly identifies the relationships between and among work attitudes and work behaviors linked to performance. The purpose of this study is to better understand the relationships between work attitudes-perceived organizational justice, perceived organizational support (POS), affective commitment-consistently associated with a key type of performance outcome among nurses' organizational citizenship behaviors (OCBs). A survey was developed and administered to frontline nurses working in the province of Ontario, Canada. Data analysis used path analytic techniques. Direct associations were identified between interpersonal justice and POS, procedural justice and POS, and POS and affective commitment to both one's supervisor and one's co-workers. Affective commitment to patients and career was directly associated with OCBs. Affective commitment to one's co-worker was directly associated with OCBs directed toward individuals, as affective commitment to one's organization was with OCBs directed toward the organization. Finally, OCBIs and OCBs were directly associated. Examining the relationships of these constructs in a single model is novel and provides new information regarding their complexity. Findings suggest that prior approaches to studying these relationships may have been undernuanced, and conceptualizations may have led to somewhat inaccurate conclusions regarding their associations. With limited resources, knowledge of nurse work attitudes can inform human resource practices and operational policies involving training programs in employee communication, transparency, interaction, support, and performance evaluation.

Background Alexithymia, a condition characterized by deficits in interpreting and regulating feelings, is a risk factor for a variety of psychiatric conditions. Little is known about how alexithymia influences the processing of emotions in music and speech. Appreciation of such emotional qualities in auditory material is fundamental to human experience and has profound consequences for functioning in daily life. We investigated the neural signature of such emotional processing in alexithymia by means of event-related potentials. Methodology Affective music and speech prosody were presented as targets following affectively congruent or incongruent visual word primes in two conditions. In two further conditions, affective music and speech prosody served as primes and visually presented words with affective connotations were presented as targets. Thirty-two participants (16 male) judged the affective valence of the targets. We tested the influence of alexithymia on cross-modal affective priming and on N400 amplitudes, indicative of individual sensitivity to an affective mismatch between words, prosody, and music. Our results indicate that the affective priming effect for prosody targets tended to be reduced with increasing scores on alexithymia, while no behavioral differences were observed for music and word targets. At the electrophysiological level, alexithymia was associated with significantly smaller N400 amplitudes in response to affectively incongruent music and speech targets, but not to incongruent word targets. Conclusions Our results suggest a reduced sensitivity for the emotional qualities of speech and music in alexithymia during affective categorization. This deficit becomes evident primarily in situations in which a verbalization of emotional information is required. PMID:21573026

There is substantive literature reporting the importance and benefits of music and music therapy programs for older adults, and more specifically for those with dementia. However, few studies have focused on how these programs may contribute to quality of life. Objectives for this exploratory study were: (a) to evaluate the potential effect of group music therapy program participation on the quality of life of older people with mild, moderate, and severe dementia living in a nursing home; (b) to identify and analyze changes in affect and participation that take place during music therapy sessions; and (c) to suggest recommendations and strategies for the design of future music therapy studies with people in various stages of dementias. Sixteen participants (15 women; 1 man), with varying level of dementia participated in 12 weekly music therapy sessions. Based on Global Deterioration Scale (GDS) scores, phases of cognitive function were as follows: mild (n = 9; GDS 3-4), moderate (n = 5; GDS 5), and severe (n = 2; GDS 6-7). Data were collected using the GENCAT scale on Quality of Life. Sessions 1, 6, and 12 were also video recorded for post-hoc analysis of facial affect and participation behaviors. There was no significant difference in quality of life scores from pre to posttest (z = -0.824; p =0.410). However, there was a significant improvement in median subscale scores for Emotional Well-being (z = -2.176, p = 0.030), and significant worsening in median subscale scores for Interpersonal Relations (z =-2.074; p = 0.038) from pre to posttest. With regard to affect and participation, a sustained high level of participation was observed throughout the intervention program. Expressions of emotion remained low. Authors discuss implications of study findings to inform and improve future research in the areas of music therapy, quality of life, and individuals with dementia. © the American Music Therapy Association 2014.

2010-01-01

Teaching and assessing the advanced competencies will continue to be a challenge. Incorporating new and nontraditional skills into an already complex and challenging clinical curriculum and practice is not easy. This makes development of methods for curricular design, teaching and assessment of anesthesiology resident and fellow performance essential. The Domains of learning, particularly the Affective Domain can serve as an organizing structure for developing objectives and selecting teaching and assessment techniques. Using the Affective Domain to select targeted teaching techniques might help foster development of key beliefs and values that underlie the advanced competencies (and sub-competencies). Targeted teaching, outside of the patient care arena, when combined with traditional clinical teaching practices, may help to ensure continued performance of desired behaviors. These include acting in a consultative role for other health professionals (ICS), providing culturally responsive care (Professionalism), using evidence to enhance the care of patients (PBLI), and advocating for quality of care and working to enhance patient safety (SBP). As educators, our aim is not only to impact knowledge, attitudes and skills, but to impact the daily behavior of our graduates.

Disruptive behavior among hospital staff can negatively affect quality of care. Motivated by a standard on disruptive behavior issued by The Joint Commission (LD 3.10), as well as the desire to improve patient care, minimize liability, and improve staff retention, hospitals are setting policies to prevent and resolve disruptive behaviors. However, it is unknown whether uniform conflict management tools are equally effective among different hospital settings. We surveyed residents and nurses to identify similarities and differences among hospital departments in the antecedents, characteristics, and outcomes of disruptive behaviors, and in the effectiveness of conflict management tools. We used a quantitative questionnaire-based assessment to examine conflict perceptions in eight different hospital departments at Rambam Medical Center in Haifa, Israel. Most participants (89 %) reported witnessing disruptive behavior either directly or in other parties; the most significant causes were identified as intense work, miscommunication, and problematic personalities. The forms of these behaviors, however, varied significantly between departments, with some more prone to expressed conflicts, while others were characterized by hidden disruptive behaviors. These outcomes were correlated by the antecedents to disruptive behavior, which in turn affected the effectiveness of alleviating strategies and tools. Some tools, such as processes for evaluating complaints, teamwork and conflict management courses, and introducing a behavioral mission statement, are effective across many antecedents. Other tools, however, are antecedent-specific, falling into two principal categories: tools directly removing a specific problem and tools that offer a way to circumvent the problem. Conflict resolution tools and strategies, based on residents and nurse perceptions, may be more effective if tailored to the specific situation, rather than using a "one-size-fits-all" approach.

Early executive functioning is an important predictor for future development of children's cognitive skills and behavioral outcomes. Parenting behavior has proven to be a key environmental determinant of child executive functioning. However, the association of parental affect and cognitions directed to the child with child executive functioning has been understudied. Therefore, in the present study we examine the associations between parental bonding (i.e., the affective tie from parent to child), parenting stress, and child executive functioning. At 26 weeks of pregnancy, and at 6 months and 24 months postpartum the quality of the maternal (N = 335) and paternal (N = 261) bond with the infant was assessed. At 24 months, postnatal parenting stress and child executive functioning were measured by means of parent-report questionnaires. Results indicated that for both mothers and fathers feelings of bonding negatively predicted experienced parenting stress over time. In addition, for both parents a negative indirect effect of bonding on child executive functioning problems was found via experienced parenting stress. These findings indicate the importance of monitoring parents who experience a low level and quality of early parent-child bonding, as this makes them vulnerable to parenting stress, consequently putting their children at risk for developing executive functioning problems.

Changing Adolescent Sleep Patterns: Factors Affecting them and the Related Problems.

Sleep affects physical growth, behavior and emotional development besides determining cognitive functioning, learning and attention especially of a growing child. Adolescence represents one of the critical transitions in the life span and is characterized by a tremendous pace in growth and change that is second only to that of infancy. Adolescent sleep patterns deserve particular attention because of the potential impact on school performance. Average sleep period in adolescents is reduced during school days to around seven hours. The reasons may be biological mainly the sleep phase delay or psychosocial and environmental. These include academic demands, social activities, sports, internet, television viewing, part-time employment, and use of mobile phone at night, peer and parental influence and socioeconomic status. These changing patterns of sleep in adolescents lead to many behavioral sleep problems like Delayed Sleep-phase Syndrome; Difficulties in falling asleep (insomnia); excessive daytime sleepiness, poor academic performance. Decreased sleep in adolescents also causes obesity and other cardio-metabolic abnormalities. This needs an integrated approach involving adolescents themselves, their parents, teachers and specialized physicians to help improve the sleep quantity and quality and lead to a better quality of life and daytime functioning in adolescents. © Journal of the Association of Physicians of India 2011.

Introduction: Professionalism is characterized by the degree of dedication displayed by individuals regarding the values and behavioral attributes of a specific career identity. Professionalism indicates attitudes that represent high levels of identification with and commitment to a specific profession. In the process of the professional development of nursing, various factors affect these obstacles which may impede the professional development of nurses and their professional behaviors. This study was carried out with the aim of determining the professional behavior of nurses in a hospital in Turkey. Methods: In this descriptive exploratory study a total of 89 nurses working in a public hospital in northwestern of Turkey were participated. Data were collected using a demographic questionnaire and Behavioral Inventory Form for Professionalism in Nursing (BIPN). Results: The result showed that mean scores on the BIPN were 5.07 (3.47). The areas with the highest levels of professional behavior were competence and continuing education 1.88 (0.34). The professionalism levels for nurses were the lowest in the areas of autonomy 0.06 (0.34), publication 0.10 (0.25), and research 0.25 (0.60). There was a statistically significant difference between the total BIPN scores and the education levels of the nurses and the working of nurses. Conclusion: The professional behavior of nurses is at a low level. Since the arrangement of the nurses’ working conditions affects their professional behaviors; therefore, development in the field of professional behaviors in nursing must be assessed and supported to increase the quality of patient care.

Stress affects health-related quality of life through several pathways, including physiological processes and health behaviors. There is always a relationship between stress (the stimulus) and coping (the response). The relationship between snacking and snackers' diet quality and stress coping is a topic overlooked in research. The study was primarily designed to determine whether energy provided by snacks and diet quality were associated with coping behaviors to manage stress. We analyzed a baseline cohort of the Healthy Aging in Neighborhoods of Diversity across the Life Span study (2004 to 2009). The sample was composed of 2,177 socioeconomically diverse African-American and white adults who resided in Baltimore, MD. Energy from snacks was calculated from 2 days of 24-hour dietary recalls collected using the US Department of Agriculture's Automated Multiple Pass Method. Snack occasions were self-reported as distinct eating occasions. Diet quality was evaluated by the Healthy Eating Index-2010. Multiple regression analyses were used to determine whether coping factors were associated with either energy provided by snacks or Healthy Eating Index-2010, adjusting for age, sex, race, socioeconomic status, education, literacy, and perceived stress. Coping was measured by the Brief COPE Inventory with instrument variables categorized into three factors: problem-focused coping, emotion-focused coping, and use of support. Perceived stress was measured with the 4-item Perceived Stress Scale. Adjusting for perceived stress and selected demographic characteristics, emotion-focused coping strategies were associated with greater energy intakes from snacks (P=0.020), and use of coping strategies involving support was positively associated with better diet quality (P=0.009). Energy contributed by snacks and diet quality were affected by the strategy that an individual used to cope with stress. The findings suggest that health professionals working with individuals seeking guidance to modify their eating practices should assess a person's coping strategies to manage stress.

How individuals deal with multiple conflicting demands is an important aspect of foraging ecology, yet work on foraging behavior has typically neglected neurologically simple organisms. Here we examine the impact of an abiotic risk (light) and energetic status on the foraging decisions of a protist, the slime mold Physarum polycephalum. We examined patch choice in a "non-risky" environment by presenting starved and non-starved P. polycephalum amoebas with a choice between two shaded food patches (one high quality, one low quality). We next examined patch choice in the presence of a conflict between foraging risk (light exposure) and food quality by presenting amoebas with a choice between a shaded, low-quality patch, and a light-exposed, high-quality patch. When both patches were shaded, 100% of amoebas selected the higher quality food patch, irrespective of food-quality differences or the individual's energetic status. When light exposure and food quality conflicted, amoebas selected the patch with the higher food quality when the quality difference between the patches was high. When the quality difference between patches was small, amoebas selected the shaded, lower quality patch.

Objective: Core alexithymic features, such as the difficulty in identifying and describing feelings, are associated with poor attachment styles and emotional trauma, which influence the capacity to regulate affect. Additionally, emotional regulation has been found to be the most commonly identified function associated with non-suicidal self-injury behavior (NSSI) in adolescents as they attempt to modulate strong emotions. However, few studies have examined the link between difficulty in identifying and describing feelings (core components of alexithymia), NSSI behaviors, quality of attachment, life stressors and suicidal ideation in healthy early adolescents. Consequently, this study aims to investigate these constructs and the relationship among them in a large non-clinical sample of adolescents. Methods: Seven hundred and nine middle school students (50.4% males), aged 10-15 years ( M = 12.6; SD = 1.06) were involved in this study. In order to investigate the variables considered in the study, the following measures were administered: the Deliberate Self-Harm Inventory exploring non-suicidal self-injurious behaviors; the Alexithymia Questionnaire for Children examining difficulty in identifying and describing feelings; the Inventory of Parent and Peer Attachment assessing the quality of parental and peer attachment; the Life Stressor Checklist-Revised outlining stressful/traumatic events and the Children's Depression Inventory evaluating suicidal ideation. Results: We found significantly positive relationships among difficulty in identifying and describing feelings, NSSI behaviors, stressful events, and suicidal ideation. Data indicated a significant negative association of difficulty in identifying and describing feelings with quality of attachment to parents and peers. Further findings highlighted that difficulty in identifying and describing feelings significantly mediated the effect of quality of attachment (parent and peer) on NSSI and suicidal ideation. Conclusion: The ability to identify and describing feelings is important to managing emotional expression and understanding the feelings of others, both crucial in attaining successful interpersonal relationships. Our data revealed that, while controlling for stressful life events, low levels of attachment may increase adolescents' difficulty in identifying and describing their own feelings, which in turn may increase the risk of both NSSI and suicidal ideation.

The aim of this study was to determine whether it is possible to predict quality of life in patients with colorectal cancer on the basis of personality dimensions from the Five-factor model. The study included 56 patients with colorectal cancer (40 men and 16 women), aged 48-87. The following instruments were used: the Questionnaire on General Information and Lifestyle Habits, the Quality of Life Scale, and the Neo Five-Factor Inventory. The results of overall quality of life estimations of colorectal cancer patients were comparable to those of healthy people. Contrary to expectations, extraversion was not a significant quality of life predictor. Neuroticism as a personality trait was the only variable which consistently proved to be highly significant across analyses in the prediction of total quality of life, satisfaction with past life, future expectations, and comparison with others. Key determinants of neuroticism are a proneness to experiencing negative affects which makes adaptation difficult, a proneness to irrational ideas, reduced impulse control, ineffective coping strategies, the perception of poor control over oneself and others, and deeming one's own resources to be insufficient to adequately cope with stress, thus resulting in a more negative quality of life estimation. These results support the conclusion that cognitive-behavioral interventions aimed at changing negative attributions, reducing tension and negative affects, acquiring more effective coping strategies, strengthening perceived personal control, redefining and re-conceptualizing quality of life, and seeking/receiving more adequate social support could lead to an improved quality of life in patients with colorectal cancer.

The evolution of risk perceptions related to bovine spongiform encephalopathy--Canadian consumer and producer behavior.

2011-01-01

In this study the dynamics of risk perceptions related to bovine spongiform encephalopathy (BSE) held by Canadian consumers and cow-calf producers were evaluated. Since the first domestic case of BSE in 2003, Canadian consumers and cow-calf producers have needed to make decisions on whether or not their purchasing/production behavior should change. Such changes in their behavior may relate to their levels of risk perceptions about BSE, risk perceptions that may be evolving over time and be affected by BSE media information available. An econometric analysis of the behavior of consumers and cow-calf producers might identify the impacts of evolving BSE risk perceptions. Risk perceptions related to BSE are evaluated through observed market behavior, an approach that differs from traditional stated preference approaches to eliciting risk perceptions at a particular point in time. BSE risk perceptions may be specified following a Social Amplification of Risk Framework (SARF) derived from sociology, psychology, and economics. Based on the SARF, various quality and quantity indices related to BSE media information are used as explanatory variables in risk perception equations. Risk perceptions are approximated using a predictive difference approach as defined by Liu et al. (1998). Results showed that Canadian consumer and cow-calf producer risk perceptions related to BSE have been amplified or attenuated by both quantity and quality of BSE media information. Government policies on risk communications need to address the different roles of BSE information in Canadian consumers' and cow-calf producers' behavior.

By the methods of site investigation, data collection and correlation analysis, the bad tourist behaviors and their environmental impacts on Xixi National Wetland Park in 2006 were studied. The occurrence probabilities of three bad tourist behaviors, i.e., picking, trampling, and littering were 6.5%, 10.3% and 12.6%, respectively. Picking probability was primarily related to the vegetation types along walkways, while the scale of heavy trampling was negatively correlated with tour distance from the entrance. Waste production by each tourist was 782 g x d(-1) on average. The waste from littering amounted for 13.6% of the total. Tourist flow fluctuations of daily, weekly, and monthly perspectives for the study area showed high seasonality and successive days of overloaded tourist flows during peak seasons, which caused an increase of bad tourist behaviors. However, the water quality in the Park was not affected because of the improvement of dredging facilities.

OBJECTIVE Parkinson's disease affects the ability to express motivation through face, body, and voice; contextual factors may facilitate or inhibit expressive behavior. The purpose of this study was to determine whether qualities of the interview context are associated with client motivational behavior in Parkinson's disease. METHOD Men and women with Parkinson's disease (N = 106) discussed 2 topics (enjoyable activity vs. frustrating activity) during an assessment with a female or male interviewer. From videotaped clips, displays of 4 categories of motivation and 12 verbal and 18 nonverbal behavioral patterns were rated. RESULTS During the discussion of enjoyable activities, participants used more positive words, smiled more, and were more facially expressive. Participants were less talkative about their negative feelings and appeared to be more apathetic with the same-gender interviewer. CONCLUSION Occupational therapy practitioners should vary the emotional tone of their questions to improve the validity of motivation assessments. PMID:20608279

2016-01-01

Patients with dementia experience various behavioral symptoms in the course of their illnesses, which greatly affect their quality of life. Current treatment modalities are not always effective, and, thus, nonpharmacological approaches are the preferred first-line therapy for managing such symptoms. They generally address the basic needs of the person with dementia and provide humane care, often producing noticeable improvements in symptoms. Thus, such therapies should precede pharmacological interventions. The following literature review of 5 publications from 2010 to 2015 evaluates the use of therapeutic touch (TT) in the management of responsive behavior in patients with dementia. The results of the review suggest that TT may be beneficial in reducing agitation in individuals with dementia; however, further research is needed to assess the use of TT.

To examine factors in the fear-avoidance model, such as pain, pain catastrophizing, fear-avoidance beliefs, physical disability, and depression and their relationships with physical and psychological quality of life in patients with rheumatic diseases. The data were obtained from 360 patients with rheumatic diseases who completed self-report measures assessing study variables. Structural equation modeling was used to examine the hypothesized relationships among factors specified in the fear-avoidance model predicting physical and psychological quality of life. Final models fit the data well, explaining 96% and 82% of the variance in physical and psychological quality of life, respectively. Higher pain catastrophizing was related to stronger fear-avoidance beliefs that had a direct negative association with physical disability and depression, which, in turn, negatively affected physical quality of life. Pain severity was also directly related to physical disability. Physical disability also affected physical quality of life indirectly through depression. The hypothesized relationships specified in the model were also confirmed for psychological quality of life. However, physical disability had an indirect association with psychological quality of life via depression. The current results underscore the significant role of cognitive, affective, and behavioral factors in perceived physical disability and their mediated detrimental effect on physical and psychological quality of life in patients with rheumatic diseases. Implications for rehabilitation The fear-avoidance model is applicable to the prediction of quality of life in patients with rheumatic diseases. As pain-catastrophizing and fear-avoidance beliefs are important factors linked to physical disability and depression, intervening these cognitive factors is necessary to improve physical function and depression in patients with rheumatic diseases. Considering the strong association between depression and physical and psychological quality of life, the assessment and treatment of the former should be included in the rehabilitation of patients with rheumatic diseases. Interventions targeting physical function and depression are likely to be effective in terms of improving physical and psychological quality of life in patients with rheumatic diseases.

Effective doctor-patient communication: an updated examination.

PubMed

Matusitz, Jonathan; Spear, Jennifer

2014-01-01

This article examines, in detail, the quality of doctor-patient interaction. Doctor-patient communication is such a powerful indicator of health care quality that it can determine patients' self-management behavior and health outcomes. The medical visit (i.e., the medical encounter) plays a pivotal role in the health care process. In fact, doctor-patient communication is one of the most essential dynamics in health care, affecting the course of patient care and patient compliance with recommendations for care. Unlike many other analyses (that often look at only one or two specific aspects of doctor-patient relationships), this analysis is more encompassing; it looks at doctor-patient communication from multiple perspectives.

Brood sex ratio is often affected by parental or environmental quality, presumably in an adaptive manner that is the sex that confers higher fitness benefits to the mother is overproduced. So far, studies on the role of parental quality have focused on parental morphology and attractiveness. However, another aspect, the partner's behavioral characteristics, may also be expected to play a role in brood sex ratio adjustment. To test this hypothesis, we investigated whether the proportion of sons in the brood is predicted by the level of territorial aggression displayed by the father, in the collared flycatcher ( Ficedula albicollis). The proportion of sons in the brood was higher in early broods and increased with paternal tarsus length. When controlling for breeding date and body size, we found a higher proportion of sons in the brood of less aggressive fathers. Male nestlings are more sensitive to the rearing environment, and the behavior of courting males may often be used by females to assess their future parental activity. Therefore, adjusting brood sex ratio to the level of male aggression could be adaptive. Our results indicate that the behavior of the partner could indeed be a significant determinant in brood sex ratio adjustment, which should not be overlooked in future studies.

The nonconscious cessation of goal pursuit: when goals and negative affect are coactivated.

2007-02-01

Extending on the recent investigation into the implicit affective processes underlying motivation and decision making, 5 studies examined the role of negative affect in moderating goal priming effects. Specifically, experimental effects on measures that typify motivational qualities of goal systems, such as keeping a goal at a heightened level of mental accessibility and exerting effort to work for a goal and experiencing desire to attain the goal, showed that the motivation and resultant operation of social goals cease when these goals are primed in temporal proximity of negatively valenced information. These goal cessation effects resulting from the mere coactivation of a goal and negative affect are discussed against the background of present research on nonconscious goal pursuit and the role of accessibility and desirability in the regulation of automatic goal-directed behavior.

2017-12-01

Drinking water contaminants pose a harm to public health. When confronted with elevated contaminate levels, individuals can take averting actions to reduce exposure, such as bottled water purchases. This study addresses a problem of national interest given that 9 to 45 million people have been affected by drinking water quality violations in each of the past 34 years. Moreover, few studies address averting behavior and avoidance costs due to water quality violations. This study assesses how responses might differ across baseline risk of impaired water quality and demographics of service area. We match a panel of weekly supermarket sales data with geocoded violations data for 67 counties in the Southeast from 2006-2015. We estimate the change in bottled water sales due to drinking water violations using a fixed effects model. Observing market behavior also allows us to calculate the cost of these averting actions. Critical findings from this study contribute to understanding how communities respond to water quality violations. We find that violations have considerable effects on bottled water consumption. Sales increase 8.1 percent due to violations related to microorganisms and 31.2 percent due to Tier 1 violations, which pose an immediate health risk. In addition, we calculate a national cost of averting actions of $26 million for microorganism violations from 2006-2015, which represents a lower-bound estimate. Averting costs vary considerably across the U.S. and some counties bear a particularly large burden, such as in California and Texas. Overall, this study provides insight into how averting behavior differs across contaminant type, water utility characteristics, and community demographics. Such knowledge can aid public health agencies, water systems, and environmental regulators to direct assistance to communities most in need.

Studies that focused on family issues have allowed a great understanding of the aspects related to its subsystems, such as parenting desire and its expectations, couples’ satisfaction and quality of child’s outcomes. All these aspects are greatly interconnected and contribute to the creation of specific family dynamics, such as the quality of family interactions. The present study focuses on intuitive co-parental behaviors and the quality of couple relationship observed during the decision process (intention and desire) to be (or become) parents. Our first goal was to explore these aspects in a cross-national sample made of Italian and Belgian heterosexual, lesbian and gay couples. We then aimed to evaluate if the degree of internalized homophobia affects co-parental alliance. The quality of couple relationship and co-parental behaviors have been evaluated through the recruitment of a group of 115 stable heterosexual, gay and lesbian couples (230 individuals, 20–50 years of age) without children, who wanted to become parents. We used the Prenatal Lausanne Trilogue Play to evaluate the Co-parental Alliance; the couple’s satisfaction was assessed with the Dyadic Adjustment Scale and the Internalized Homophobia with the MISS-LG. In line with the existent literature, the analysis did not find any difference between lesbian, gay and heterosexual couples in terms of co-parental alliance. High levels of couple adjustment lead to better parental performances among both Italian and Belgian couples. The results suggest also that sexual stigma differs from one country to another, and it has an impact on the capability of managing co-parenting. Clinical implications should be verified in further longitudinal studies in order to observe the impact on the inter-generational transmission of psychopathology. PMID:28261120

Crohn's disease is an inflammatory bowel disease of unknown etiology. Its chronic nature, as well as symptoms of intestinal and overall significantly impedes the daily functioning of patients. Alternately occurring periods of exacerbation and remission are the cause of reduced quality of life of patients. Understanding the factors that caused the decrease in the quality of life, it allows us to understand the behavior and the situation of the patient and the ability to cope with stress caused by the disease. The aim of the study was to analyze the factors affecting the quality of life of people with Crohn's disease. The study group consisted of 50 people diagnosed with Crohn's disease. Respondents were treated at the Department of General Surgery and Colorectal Medical University of Lodz and Gastroenterological Clinic at the University Clinical Hospital No. 1 in Lodz. Quality of Life Survey was carried out by a diagnostic survey using a research tool SF-36v2 and surveys of its own design. Analysis of the results demonstrated that the quality of life of patients with Crohn's disease was reduced, especially during exacerbations. Evaluation of the quality of life of respondents in physical terms was slightly higher than in the mental aspect. Higher education subjects and the lack of need for surgical treatment significantly improves the quality of life. The occurrence of chronic disease reduces the quality of life of respondents. Elderly patients are better able to adapt to the difficult situation caused by the disease. The quality of life of women and men is at a similar level and patients in remission of the disease have a better quality of life of patients during exacerbations.

Patients' initial beliefs about the success of a given pain treatment are shown to have an important influence on the final treatment outcome. The aims of the paper are to assess determinants of patients' treatment expectancy and to examine the extent to which treatment expectancy predicts the short-term and long-term outcome of cognitive-behavioral treatment of chronic pain. This study employs the data of 2 pooled randomized clinical trials evaluating the effectiveness of cognitive-behavioral interventions for 171 patients with fibromyalgia and chronic low back pain. Pretreatment and posttreatment expectancy were measured by a short questionnaire, which was based on the procedure by Borkovec and Nau. Four composite outcome variables (pain coping and control, motoric behavior, negative affect, and quality of life) were measured before and after the intervention and at 12 months follow-up. Furthermore, several patient characteristics were taken into account. Patients with higher treatment expectancies significantly received less disability compensation and were less fearful. A regression model of 3 factors (better pain coping and control, active and positive interpretation of pain, and less disability compensation) significantly explained 10% of the variance in pretreatment expectancy. Pretreatment expectancy significantly predicted each of the 4 outcome measures immediately after treatment and at 12 months follow-up. This study corroborates the importance of treatment expectation before entering a cognitive-behavioral intervention in patients with chronic musculoskeletal pain.

Psychological interventions for behavioral adjustments in diabetes care - a value-based approach to disease control.

Psychological aspects of a person, such as the personal value and belief systems, cognition and emotion, form the basis of human health behaviors, which, in turn, influence self-management, self-efficacy, quality of life, disease control and clinical outcomes in people with chronic diseases such as diabetes mellitus. However, psychological, psychosocial and behavioral interventions aimed at these groups of patients have yielded inconsistent effects in terms of clinical outcomes in clinical trials. This might have been due to differing conceptualization of health behavioral theories and models in the interventions. Assimilating different theories of human behavior, this narrative review attempts to demonstrate the potential modulatory effects of intrinsic values on cognitive and affective health-directed interventions. Interventions that utilize modification of cognition alone via education or that focuses on both cognitive and emotional levels are hardly adequate to initiate health-seeking behavior and much less to sustain them. People who are aware of their own personal values and purpose in life would be more motivated to practice good health-related behavior and persevere in them.

A growing body of research suggests that people who are more deeply involved in religion may be more likely to adopt beneficial health behaviors. However, religion is a complex phenomenon, and as a result, religion may affect health behaviors in a number of ways. The purpose of the current study was to see whether a sacred view of the body (i.e., belief that the body is the temple of God) is associated with better health behavior. It was proposed that the relationship between a sacred body view and health behavior will emerge only among study participants who have a stronger sense of religiously oriented control (i.e., stronger God-mediated control beliefs). Five positive health behaviors were evaluated: more frequent strenuous exercise, more frequent moderate exercise, more frequent consumption of fruits and vegetables, higher quality sleep, and the adoption of healthy lifestyles. Data from a recent nationwide sample reveal that a sacred body view is associated with each health behavior, but only among study participants who have a strong religiously oriented sense of control.

Nonadherence to immunosuppressive medication increases the risk of graft failure. Maladaptive emotion regulation strategies (ERS) seem to be a risk factor for nonadherence, whereas for patients in relationships spousal support appears as a protective resource. Emotional arousal, objectively measured by the fundamental frequency (f 0 ) during spousal supportive communication is associated with supportive behavior. This study examined the relationship between beliefs about immunosuppressive medication, quality of life, ERS, emotions and emotional arousal, assessed during social support interactions of both spouses of N=50 couples after kidney transplantation. Maladaptive ERS of the transplant recipient were associated with lower mental quality of life of the partner, marginally higher own negative affect and lower beliefs about medication. Maladaptive ERS of the partner showed negative correlations with own mental quality of life. Regarding f 0 , gender differences were found. Higher f 0 of the male transplant recipient were associated with more maladaptive ERS of the female partner. Marginally significate correlations were found with lower own beliefs about medication. Higher f 0 of the wife of the male transplant recipient showed correlations with lower own positive affect, more negative affect of the male patient and lower beliefs about medication. Higher f 0 of female transplant recipients were associated with lower own maladaptive ERS and lower maladaptive ERS of the husband. The findings support the relevance of early interventions focusing on identifying and modifying maladaptive ERS for both the patient and partner. © Georg Thieme Verlag KG Stuttgart · New York.

Clinical trials of behavioral interventions seek to enhance evidence-based health care. However, in case the quality of standard care provided to control conditions varies between studies and affects outcomes, intervention effects cannot be directly interpreted or compared. The objective of the present study was to examine whether standard care quality (SCQ) could be reliably assessed, varies between studies of highly active antiretroviral HIV-adherence interventions, and is related to the proportion of patients achieving an undetectable viral load ("success rate"). Databases were searched for relevant articles. Authors of selected studies retrospectively completed a checklist with standard care activities, which were coded to compute SCQ scores. The relationship between SCQ and the success rates was examined using meta-regression. Cronbach's alpha, variability in SCQ, and relation between SCQ and success rate. Reliability of the SCQ instrument was high (Cronbach's alpha = .91). SCQ scores ranged from 3.7 to 27.8 (total range = 0-30) and were highly predictive of success rate (p = .002). Variation in SCQ provided to control groups may substantially influence effect sizes of behavior change interventions. Future trials should therefore assess and report SCQ, and meta-analyses should control for variability in SCQ, thereby producing more accurate estimates of the effectiveness of behavior change interventions.

Many organizations are developing health care price information tools for consumers. However, consumers may avoid low-price care if they perceive price to be associated with quality. We conducted a nationally representative survey to examine whether consumers perceive that price and quality are associated and whether the way in which questions are framed affects consumers' responses. Most Americans (58-71 percent, depending on question framing) did not think that price and quality are associated, but a substantial minority did perceive an association (21-24 percent) or were unsure whether there was one (8-16 percent). Responses to questions framed in terms of high price and high quality differed from responses to questions framed in terms of low price and low quality. People who had compared prices were more likely than those who had not compared prices to perceive that price and quality were associated. We explore implications of these findings, including how behavioral economics can inform approaches to helping consumers use price and quality information.

ATP-sensitive potassium-channel inhibitor glibenclamide attenuates HPA axis hyperactivity, depression- and anxiety-related symptoms in a rat model of Alzheimer's disease.

2018-03-01

Affective disorders including depression and anxiety are among the most prevalent behavioral abnormalities in patients with Alzheimer's disease (AD), which affect the quality of life and progression of the disease. Dysregulation of the hypothalamic-pituitary-adrenal-(HPA) axis has been reported in affective disorders and AD. Recent studies revealed that current antidepressant drugs are not completely effective for treating anxiety- and depression-related disorders in people with dementia. ATP-sensitive-potassium-(K ATP ) channels are well-known to be involved in AD pathophysiology, HPA axis function and the pathogenesis of depression and anxiety-related behaviors. Thus, targeting of K ATP channel may be a potential therapeutic strategy in AD. Hence, we investigated the effects of intracerebroventricular injection of Aβ25-35 alone or in combination with glibenclamide, K ATP channel inhibitor on depression- and anxiety-related behaviors as well as HPA axis response to stress in rats. To do this, non-Aβ25-35- and Aβ25-35-treated rats were orally treated with glibenclamide, then the behavioral consequences were assessed using sucrose preference, forced swim, light-dark box and plus maze tests. Stress-induced corticosterone levels following forced swim and plus maze tests were also evaluated as indicative of abnormal HPA-axis-function. Aβ25-35 induced HPA axis hyperreactivity and increased depression- and anxiety-related symptoms in rats. Our results showed that blockade of K ATP channels with glibenclamide decreased depression- and anxiety-related behaviors by normalizing HPA axis activity in Aβ25-35-treated rats. This study provides additional evidence that Aβ administration can induce depression- and anxiety-like symptoms in rodents, and suggests that K ATP channel inhibitors may be a plausible therapeutic strategy for treating affective disorders in AD patients.

In recent years with technological advances, instruments deployed on diving marine animals have been used to sample the environment in addition to their behavior. Of all oceanographic variables one of the most valuable and easiest to record is temperature. Here we report on a series of lab calibration and field validation experiments that consider the accuracy of temperature measurements from animal borne ocean samplers. Additionally we consider whether sampling frequency or animal behavior affects the quality of the temperature data collected by marine animals. Rapid response, external temperature sensors on eight Wildlife Computers MK9 time-depth recorders (TDRs) were calibrated using water baths at the Naval Postgraduate School (Monterey, CA). These water baths are calibrated using a platinum thermistor to 0.001° C. Instruments from different production batches were calibrated before and after deployments on adult female northern elephant seals, to examine tag performance over time and under `normal' usage. Tag performance in the field was validated by comparisons with temperature data from a Seabird CTD. In April/May of 2004, casts to 200m were performed over the Monterey Canyon using a CTD array carrying MK9s. These casts were performed before and after the release of a juvenile elephant seal from the boat. The seal was also carrying an MK9 TDR, allowing the assessment of any animal effect on temperature profiles. Sampling frequency during these field validations was set at one second intervals and the data from TDRs on both the CTD and the seals was sub-sampled at four, eight, 30 and 300 (5 min) seconds. The sub-sampled data was used to determine thermocline depth, a thermocline depth zone and temperature gradients and assess whether sampling frequency or animal behavior affects the quality of temperature data. Preliminary analyses indicate that temperature sensors deployed on elephant seals can provide water column temperature data of high quality and precision.

This study focuses on career development processes and options for older workers in South Korea and explores how career coaching enhances their career development efforts and transition needs. The purpose of this study is to investigate the structural relationship between older employees' goal-setting, self-efficacy, and job-search behavior mediated by career coaching. A total of 249 participants were recruited in a metropolitan city in South Korea. Based on the literature review, hypotheses were developed and tested on the structural model and the following findings were revealed. First, the findings indicate a positive effect of self-efficacy on older workers' job-search behavior. Second, the value of career coaching was found to affect older workers' job-search behavior in the South Korean context. Third, career-goal commitment alone did not have a positive significant effect on job-search behavior, but it was influential through the mediating process of the perceived quality of the career coaching program provided by an employment center in South Korea.

Prior studies evaluating associations between parental affect and parenting behavior have typically focused on either mothers or fathers despite evidence suggesting that affect and parenting behavior may be interdependent among couples. This study addressed this gap in the literature by evaluating associations between self-reported affect and parenting behavior using an actor-partner interdependence analysis among a sample of 53 mother-father dyads of 3- to 5-year-old children. Results suggested that mothers' and fathers' negative affect, as well as mothers' and fathers' positive affect, were positively associated. Both mothers' and fathers' negative affect were negatively associated with fathers' positive affect. Mothers' and fathers' harsh/negative parenting behavior, and supportive/engaged parenting behavior, were positively associated. Furthermore, mothers' negative affect was positively associated with mothers' and fathers' harsh/negative parenting behavior while mothers' positive affect was negatively associated with mothers' harsh/negative behavior and positively associated with mothers' supportive/engaged behavior. Fathers' negative affect was positively associated with fathers' supportive/engaged parenting behavior, while fathers' positive affect was positively associated with mothers' and fathers' supportive/engaged behavior. Results highlight the importance of conceptualizing and measuring characteristics of both mothers and fathers, if applicable, when researching the dynamics of interpersonal relationships within families. © 2014 FPI, Inc.

Affect can have a significant influence on decision-making processes and subsequent choice. One particularly relevant type of negative affect is anxiety, which serves to enhance responses to threatening stimuli or situations. In its exaggerated form, it can lead to psychiatric disorders, with detrimental consequences for quality of life, including the ability to make choices. This study investigated, for the first time, how pathological anxiety affects risk-taking behavior. In this study, 20 anxious participants meeting Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria for either generalized anxiety disorder (n = 10) and for panic attack disorder (n = 10), as well as 20 matched nonanxious controls, performed a gambling task. To investigate the tendency toward either a risk-seeking or a risk-averse behavior, we employed a task that did not allow for learning from outcomes. Anxious participants made significantly fewer risky choices than matched nonanxious participants. Specifically, they become risk-avoidant after gains. Moreover, anxious participants not only were less happy after gains but were also less sad after losses, and they also evinced less desire to change their choices after losses than did nonanxious participants. Importantly, whereas the desire to switch choice was followed by actual choice switch for all participants, happiness directly predicted subsequent risky choices, particularly in the nonanxious participants. Further analyses revealed that the anxious participants' risk-avoidance behavior was independent of different types of anxiety disorder (panic attack disorder and generalized anxiety disorder) as well as of the effects of psychotropic drugs treatment. This study demonstrates a specific role for anxiety in individual decision making. In particular, hypersensitivity to potential threats and pessimistic evaluation of future events reduced risk-taking behavior. PsycINFO Database Record (c) 2012 APA, all rights reserved.

Converging evidence implicates the regulatory neuropeptide Y (NPY) in anxiety- and depression-related behaviors. The present study sought to assess whether there is an association between the magnitude of behavioral responses to stress and patterns of NPY in selected brain areas, and subsequently, whether pharmacological manipulations of NPY levels affect behavior in an animal model of PTSD. Animals were exposed to predator-scent stress for 15 min. Behaviors were assessed with the elevated plus maze and acoustic startle response tests 7 days later. Preset cutoff criteria classified exposed animals according to their individual behavioral responses. NPY protein levels were assessed in specific brain regions 8 days after the exposure. The behavioral effects of NPY agonist, NPY-Y1-receptor antagonist, or placebo administered centrally 1 h post-exposure were evaluated in the same manner. Immunohistochemical technique was used to detect the expression of the NPY, NPY-Y1 receptor, brain-derived neurotrophic factor, and GR 1 day after the behavioral tests. Animals whose behavior was extremely disrupted (EBR) selectively displayed significant downregulation of NPY in the hippocampus, periaqueductal gray, and amygdala, compared with animals whose behavior was minimally (MBR) or partially (PBR) disrupted, and with unexposed controls. One-hour post-exposure treatment with NPY significantly reduced prevalence rates of EBR and reduced trauma-cue freezing responses, compared with vehicle controls. The distinctive pattern of NPY downregulation that correlated with EBR as well as the resounding behavioral effects of pharmacological manipulation of NPY indicates an intimate association between NPY and behavioral responses to stress, and potentially between molecular and psychopathological processes, which underlie the observed changes in behavior. The protective qualities attributed to NPY are supported by the extreme reduction of its expression in animals severely affected by the stressor and imply a role in promoting resilience and/or recovery.

How Affectively-Based and Cognitively-Based Attitudes Drive Intergroup Behaviours: The Moderating Role of Affective-Cognitive Consistency

2013-01-01

The moderating role of affective-cognitive consistency in the effects of affectively-based and cognitively-based attitudes on consummatory and instrumental behaviors was explored using two experimental studies in the intergroup context. Study 1 revealed that affectively-based attitudes were better predictors than cognitively-based attitudes regardless of affective-cognitive consistency for consummatory behaviors (e.g., undergraduates’ supportive behaviors toward government officials). Study 2, which investigated task groups’ supportive behaviors toward an immediate supervisory group, found that for these instrumental behaviors cognitively-based attitudes were better predictors than affectively-based attitudes only when affective-cognitive consistency was high. The present research also examined the mechanism by which affective-cognitive consistency moderates the relative roles of affectively-based and cognitively-based attitudes in attitude-behavior consistency. Results indicated that attitude-behavior consistency is eroded primarily because of the weaker relationship of affective or cognitive components to behaviors than to general attitudes. The reciprocal implications of research on attitudes and work on intergroup relations are considered. PMID:24244751

The purposes of this study were to develop and validate the Empathic-Affective Response Scale, and to examine the relationship of empathic-affective responses with prosocial behaviors and aggressive behaviors. Undergraduate students (N = 443) participated in a questionnaire study. The results of factor analysis indicated that empathic-affective responses involved three factors: (a) sharing and good feeling toward others' positive affect, (b) sharing of negative affect and (c) sympathy toward others' negative affect. Correlations with other empathy-related scales and internal consistency suggested that this scale has satisfactory validity and reliability. Cluster analysis revealed that participants were clustered into four groups: high-empathic group, low-empathic group, insufficient positive affective response group and insufficient negative affective response group. Additional analysis showed the frequency of prosocial behaviors in high-empathic group was highest in all groups. On the other hand, the frequency of aggressive behaviors in both insufficient positive affective response group and low-empathic group were higher than others' groups. The results indicated that empathic-affective responses toward positive affect are also very important to predict prosocial behaviors and aggressive behaviors.

Socially indiscriminate attachment behavior has been repeatedly observed among institutionally reared children. Socially indiscriminate behavior has also been associated with aggression and hyperactivity. However, available data rely heavily on caregiver report of indiscriminate behavior. In addition, few studies have been conducted with samples of home-reared infants exposed to inadequate care. The current study aimed to develop a reliable laboratory measure of socially indiscriminate forms of attachment behavior based on direct observation and to validate the measure against assessments of early care and later behavior problems among home-reared infants. Strange Situation episodes of 75 socially at-risk mother-infant dyads were coded for infant indiscriminate attachment behavior on the newly developed Rating for Infant-Stranger Engagement. After controlling for infant insecure-organized and disorganized behavior in all analyses, extent of infant-stranger engagement at 18 months was significantly related to serious caregiving risk (maltreatment or maternal psychiatric hospitalization), observed quality of disrupted maternal affective communication, and aggressive and hyperactive behavior problems at age 5. Results are discussed in relation to the convergent and discriminant validity of the new measure and to the potential utility of a standardized observational measure of indiscriminate attachment behavior. Further validation is needed in relation to caregiver report measures of indiscriminate behavior.

Gabapentin (GBP) is a first-line therapy for neuropathic pain, but its mechanisms and sites of action remain uncertain. We investigated GBP-induced modulation of neuropathic pain following spinal nerve ligation (SNL) in rats. Intravenous or intrathecal GBP reversed evoked mechanical hypersensitivity and produced conditioned place preference (CPP) and dopamine (DA) release in the nucleus accumbens (NAc) selectively in SNL rats. Spinal GBP also significantly inhibited dorsal horn wide-dynamic-range neuronal responses to a range of evoked stimuli in SNL rats. By contrast, GBP microinjected bilaterally into the rostral anterior cingulate cortex (rACC), produced CPP, and elicited NAc DA release selectively in SNL rats but did not reverse tactile allodynia and had marginal effects on wide-dynamic-range neuronal activity. Moreover, blockade of endogenous opioid signaling in the rACC prevented intravenous GBP-induced CPP and NAc DA release but failed to block its inhibition of tactile allodynia. Gabapentin, therefore, can potentially act to produce its pain relieving effects by (a) inhibition of injury-induced spinal neuronal excitability, evoked hypersensitivity, and ongoing pain and (b) selective supraspinal modulation of affective qualities of pain, without alteration of reflexive behaviors. Consistent with previous findings of pain relief from nonopioid analgesics, GBP requires engagement of rACC endogenous opioid circuits and downstream activation of mesolimbic reward circuits reflected in learned pain-motivated behaviors. These findings support the partial separation of sensory and affective dimensions of pain in this experimental model and suggest that modulation of affective-motivational qualities of pain may be the preferential mechanism of GBP's analgesic effects in patients.

Trait-based Affective Processes in Alcohol-Involved Risk Behaviors

2012-01-01

This study tested a theoretical model of alcohol use, markers of extreme intoxication, and risk behavior as a function of trait affect, distress tolerance, and affect-based behavior dysregulation. Positive affective pathways to risk behavior were primarily expected to be indirect via high levels of alcohol use, while negative affect paths were expected to be more directly associated with engagement in risk behavior. In addition, we expected trait affectivity and distress tolerance would primarily exhibit relationships with alcohol use and problems through behavioral dysregulation occurring during extreme affective states. To evaluate these hypotheses, we tested a SEM with three alcohol–related outcomes: “Typical” alcohol use, “blackout” drinking,” and risk behavior. Results were complex, but generally supported the hypotheses. High trait negative affect and low tolerance for affective distress contribute to difficulty controlling behavior when negatively aroused and this is directly associated with increased risk behavior when drinking. In contrast, associations between positive urgency and risk behaviors are indirect via increased alcohol consumption. Positive affectivity exhibited both inverse and positive effects in the model, with the net effect on alcohol outcomes being insignificant. These findings contribute important information about the distinct pathways between affect, alcohol use, and alcohol-involved risk behavior among college students. PMID:22770825

This study of Israeli and American preadolescent children examined characteristics of friendship in 44 children with high-functioning autism spectrum disorder (HFASD) compared to 38 typically developing children (TYP), as they interacted with a close friend Participants were 8-12 years of age (HFASD: Israel, n = 24; USA, n = 20; TYP: Israel, n = 23; USA, n = 15), and were matched on SES, receptive language vocabulary, child age, and gender (each study group included one girl). Multidimensional assessments included: individual behaviors of target children and observed child-friend interactions during construction and drawing scenarios; target child's and friend's self-perceived mutual friendship qualities; and mother-reported characteristics (friendship's duration/frequency; friend's age/gender/disability status). Overall, children with HFASD displayed a number of differences on individual and dyadic friendship measures. Both age and verbal abilities affected friendship behaviors. Children with HFASD and their friends perceived friendship qualities similarly, suggesting that preadolescents with HFASD have capacities for interpersonal awareness. Between-group similarities also emerged on several complex social behaviors, suggesting that friendship follows a developmental trajectory in autism and may enhance social interaction skills in autism.

We examined how the amplification of 3 within-person processes (behavioral reactivity to interpersonal perceptions, affect reactivity to interpersonal perceptions, and behavioral reactivity to a person's own affect) accounts for greater quarrelsome behavior among individuals with borderline personality disorder (BPD). Using an event-contingent recording (ECR) methodology, individuals with BPD (N = 38) and community controls (N = 31) reported on their negative affect, quarrelsome behavior, and perceptions of the interaction partner's agreeable-quarrelsome behavior in interpersonal events during a 20-day period. Behavioral reactivity to negative affect was similar in both groups. However, behavioral reactivity and affect reactivity to interpersonal perceptions were elevated in individuals with BPD relative to community controls; specifically, individuals with BPD reported more quarrelsome behavior and more negative affect during interactions in which they perceived others as more cold-quarrelsome. Greater negative affect reactivity to perceptions of other's cold-quarrelsome behavior partly accounted for the increased quarrelsome behavior reported by individuals with BPD during these interactions. This pattern of results suggests a cycle in which the perception of cold-quarrelsome behavior in others triggers elevated negative affect and quarrelsome behavior in individuals with BPD, which subsequently led to more quarrelsome behavior from their interaction partners, which leads to perceptions of others as cold-quarrelsomeness, which begins the cycle anew. 2013 APA, all rights reserved

Pain and anxiety are commonly experienced by cancer patients and both significantly impair their quality of life. Some authors claim that there is a relationship between pain and anxiety, while others suggest that there is not a direct association. In any case, there is indeed a consensus that anxiety impairs the pain condition beyond be under diagnosed and undertreated in cancer pain patients. Herein we investigated if rats presenting heat hyperalgesia induced by orofacial cancer cell inoculation would display anxiety-like behaviors. In addition, we evaluated if pain blockade would result in alleviation of anxiety behaviors, as well as, if blockade of anxiety would result in pain relief. Orofacial cancer was induced in male Wistar rats by inoculation of Walker-256 cells into the right vibrissal pad. Heat facial hyperalgesia was assessed on day 6 after the inoculation, and on this time point rats were submitted to the elevated plus maze and the light-dark transition tests. The influence of lidocaine and midazolam on heat hyperalgesia and anxiety-like behaviors was assessed. The peak of facial heat hyperalgesia was detected 6 days after cancer cells inoculation, and at this time point, rats exhibited increased anxiety-like behaviors. Local treatment with lidocaine (2%/50μL) caused a marked reduction of heat hyperalgesia, but failed to affect the anxiety-like behaviors, while midazolam (0.5mg/kg, i.p.) treatment failed to change the heat threshold, but induced an anxiolytic-like effect. Altogether, our data demonstrated that rats with orofacial cancer present pain- and anxiety-like behaviors, but brief heat hyperalgesia relief does not affect the anxiety-like behaviors, and vice-versa, in our experimental conditions.

Quality of Care for Patients with Chronic Respiratory Diseases: Data for Accreditation Plan in Primary Healthcare.

PubMed

Kurpas, Donata; Szwamel, Katarzyna; Mroczek, Bożena

There are scarce reports in the literature on factors affecting the assessment of the quality of care for patients with chronic respiratory diseases. Such information is relevant in the accreditation process on implementing the healthcare. The study group consisted of 133 adult patients with chronic respiratory diseases and 125 adult patients with chronic non-respiratory diseases. In the present study, the level of satisfaction from healthcare provided by the primary healthcare unit, disease acceptance, quality of life, health behaviors, and met needs were examined, as well as associations between variables with the use of correspondence analysis. The results are that in patients with chronic respiratory diseases an increase in satisfaction depends on the improvement of well-being in the mental sphere. The lack of problems with obtaining a referral to a specialist and a higher level of fulfilled needs also have a positive effect. Additionally, low levels of satisfaction should be expected in those patients with chronic respiratory diseases who wait for an appointment in front of the office for a long time, report problems with obtaining a referral to additional tests, present a low level of health behaviors, and have a low index of benefits.

Overstated evidence for short-term effects of violent games on affect and behavior: A reanalysis of Anderson et al. (2010).

Violent video games are theorized to be a significant cause of aggressive thoughts, feelings, and behaviors. Important evidence for this claim comes from a large meta-analysis by Anderson and colleagues (2010), who found effects of violent games in experimental, cross-sectional, and longitudinal research. In that meta-analysis, the authors argued that there is little publication or analytic bias in the literature, an argument supported by their use of the trim-and-fill procedure. In the present manuscript, we reexamine their meta-analysis using a wider array of techniques for detecting bias and adjusting effect sizes. Our conclusions differ from those of Anderson and colleagues in 3 salient ways. First, we detect substantial publication bias in experimental research on the effects of violent games on aggressive affect and aggressive behavior. Second, after adjustment for bias, the effects of violent games on aggressive behavior in experimental research are estimated as being very small, and estimates of effects on aggressive affect are much reduced. In contrast, the cross-sectional literature finds correlations that appear largely unbiased. Third, experiments meeting the original authors' criteria for methodological quality do not yield larger adjusted effects than other experiments, but instead yield larger indications of bias, indicating that perhaps they were selected for significance. We outline future directions for stronger experimental research. The results indicate the need for an open, transparent, and preregistered research process to test the existence of the basic phenomenon.

Embodied affectivity: on moving and being moved

PubMed Central

Fuchs, Thomas; Koch, Sabine C.

2014-01-01

There is a growing body of research indicating that bodily sensation and behavior strongly influences one's emotional reaction toward certain situations or objects. On this background, a framework model of embodied affectivity1 is suggested: we regard emotions as resulting from the circular interaction between affective qualities or affordances in the environment and the subject's bodily resonance, be it in the form of sensations, postures, expressive movements or movement tendencies. Motion and emotion are thus intrinsically connected: one is moved by movement (perception; impression; affection2) and moved to move (action; expression; e-motion). Through its resonance, the body functions as a medium of emotional perception: it colors or charges self-experience and the environment with affective valences while it remains itself in the background of one's own awareness. This model is then applied to emotional social understanding or interaffectivity which is regarded as an intertwinement of two cycles of embodied affectivity, thus continuously modifying each partner's affective affordances and bodily resonance. We conclude with considerations of how embodied affectivity is altered in psychopathology and can be addressed in psychotherapy of the embodied self. PMID:24936191

The purpose of this study was to distinguish between the influence of attachment styles and behaviors on marital quality for couples. Data were gathered from 680 couples in a married relationship. Results showed attachment style and behaviors predicted marital quality for both men and women, with higher levels of attachment related to greater quality. Attachment behaviors predicted more of the variance in quality than did styles. Specific implications regarding how therapists may wish to foster behaviors that promote attachment security in marriages are discussed. © 2015 Family Process Institute.

Consumer preference, behavior and perception about meat and meat products: an overview.

PubMed

Font-I-Furnols, Maria; Guerrero, Luis

2014-11-01

Meat and meat products currently represent an important source of protein in the human diet, and their quality varies according to intrinsic and extrinsic parameters that can sometimes be shaped to make a product more desirable. Because consumers are the final step in the production chain, it is useful to identify which factors affect their behavioral patterns. This would allow the meat sector to better satisfy consumer expectations, demands and needs. This paper focuses on features that might influence consumer behavior, preferences and their perception of meat and meat products with respect to psychological, sensory and marketing aspects. This multidisciplinary approach includes evaluating psychological issues such as attitudes, beliefs, and expectations; sensory properties such as appearance, texture, flavor and odor; and marketing-related aspects such as price and brand.

Kogan, Steven M.; Brody, Gene H.; Chen, Yi-fu

2011-01-01

A 3-wave model linking natural mentoring relationships to externalizing behavior was tested with 345 rural African American emerging adults in their final year of high school. Structural equation models were executed linking multi-informant reports of mentor-emerging adult relationship quality with youths’ externalizing behavior 18 months later. Consistent with our primary hypotheses, emerging adults whose relationships with their natural mentors were characterized by instrumental and emotional support and affectively positive interactions reported lower levels of anger, rule-breaking behavior, and aggression. These effects emerged independent of the influences of family support and youth gender. Two intrapersonal processes, a future orientation and self-regulation, emerged as mediators of the influence of natural mentoring relationships. The influence of natural mentors was most pronounced for emerging adults experiencing high levels of life stress. PMID:21293917

Conflict, social support, and relationship quality: an observational study of heterosexual, gay male, and lesbian couples' communication.

2003-09-01

Data from 42 heterosexual, 46 gay male, and 33 lesbian couples were used to assess the contribution of conflict and support discussions to relationship quality. Couples completed questionnaires, and videotaped discussions were coded for levels of negative and positive behaviors. Correlations showed that behaviors were associated with relationship quality in the expected directions. Hierarchical linear modeling analyses assessed the unique contributions of individual and dyadic behaviors to the variability of relationship quality. The findings indicated that, beyond the contribution of individual negative behaviors in the conflict task, the variables of dyadic positive behaviors in the conflict task, individual positive behaviors in the support task, and perceived help accounted for unexplained variance in relationship quality. There were no differences between types of couples on levels of behaviors or on their contributions to relationship quality.

Assistive technologies can improve the quality of life of people diagnosed with different forms of social communication disorders. We report on the design and evaluation of an affective avatar aimed at engaging the user in a social interaction with the purpose of assisting in communication therapies. A human-avatar taxonomy is proposed to assist the design of affective avatars aimed at addressing social communication disorder. The avatar was evaluated with 30 subjects to assess how effectively it conveys the desired emotion and elicits empathy from the user. Results provide evidence that users become used to the avatar after a number of interactions, and they perceive the defined behavior as being logical. The users' interactions with the avatar entail affective reactions, including the mimic emotions that users felt, and establish a preliminary ground truth about prototypic empathic interactions with avatars that is being used to train learning algorithms to support social communication disorder evaluation.

Activity situations on an Alzheimer's disease special care unit and resident environmental interactions, time use, and affect.

Routine activity situations on an Alzheimer's disease (AD) special care unit were examined with respect to residents' social and physical environmental interactions, time use, and apparent affect. Using a computer-assisted observational tool, observers recorded prevailing activity situations and corresponding behaviors and affects of seven residents every 10 minutes, from 8:00 AM to 8:00 PM, across four days. Although meals/snacks and some activity groups were positively associated with use of physical objects and engagement in activities, residents were predominantly environmentally disengaged, inactive, or without positive affects during the most prevalent activity situations of background media, downtime, and television. Findings suggest that routine activity situations may act as potent environmental influences on the quality of life (QOL) of people with AD and mediate the effectiveness of other environmental interventions undertaken on their behalf.

Alzheimer disease: diagnosis, costs, and dimensions of treatment.

PubMed

DeKosky, S T; Orgogozo, J M

2001-08-01

Alzheimer disease (AD) is the most frequent cause of dementia in developed Western countries. Over time, affected patients invariably develop cognitive and functional decline, and most develop early or later behavioral disturbances. Declining cognitive and functional abilities contribute to loss of independent living and feelings of denial, confusion, fear and guilt until, finally, the patient loses most abilities to think, move, speak, or perceive. As patients' dependency on assistance increases, the level of caregiver strain rises. The caregiver may develop feelings of anger, grief, loneliness and resentment, and the health and well-being of most caregivers are often affected. Approximately 3-4 million people currently have AD in the USA, at an annual cost of up to US$100 billion, and the disease is expected to reach epidemic proportions by 2020. To achieve a clinically relevant, long-term outcome, pharmacotherapy must have sustained favorable effects on cognitive, functional and behavioral symptoms of AD. Slowing the development of these features of the disease will mean a long-term improvement in quality of life for patients and caregivers. Postponing the emergence of behavioral symptoms would bring about direct beneficial effects on patients with AD and their families, help delay long-term care placement and lower costs.

Metabolic, Behavioral and Reproductive Effects of Vertical Sleeve Gastrectomy in an Obese Rat Model of Polycystic Ovary Syndrome

Introduction Polycystic ovary syndrome (PCOS) is the most common endocrinopathy affecting women of reproductive age. Its clinical expression is diverse, including metabolic, behavioral and reproductive effects, with many affected by obesity and decreased quality of life. Women with PCOS who have undergone surgically-induced weight loss have reported tremendous benefit, not only with weight loss, but also improvement of hyperandrogenism and menstrual cyclicity. Methods In a rat model of PCOS achieved via chronic administration of dihydrotestosterone (DHT) exposure, we investigated the ability of bariatric surgery, specifically vertical sleeve gastrectomy (VSG), to ameliorate the metabolic, behavioral and reproductive abnormalities invoked by this PCOS model. Results We found that DHT-treatment combined with exposure to a high-fat diet resulted in increased body weight and body fat, impaired fasting glucose, hirsutism, anxiety and irregular cycles. VSG resulted in reduced food intake, body weight and adiposity with improved fasting glucose and triglycerides. VSG induced lower basal corticosterone levels and attenuated stress responsivity. Once the DHT levels decreased to normal, regular estrous cyclicity was also restored. Conclusion VSG, therefore, improved PCOS manifestations in a comprehensive manner and may represent a potential therapeutic approach for specific aspects of PCOS. PMID:24408363

Objectives: (1) To explore the effects on women's lives by heavy or irregular menstrual bleeding; (2) To examine whether aspects of women's lives most affected by heavy or irregular menstrual bleeding were adequately addressed by questions that are frequently used in clinical encounters and available questionnaires. Methods: We conducted four focus group sessions with a total of 25 English-speaking women who had reported abnormal uterine bleeding. Discussions included open-ended questions that pertained to bleeding, aspects of life affected by bleeding, and questions frequently used in clinical settings about bleeding and quality of life. Results: We identified five themes that reflected how women's lives were affected by heavy or irregular menstrual bleeding: irritation/inconvenience, bleeding-associated pain, self-consciousness about odor, social embarrassment, and ritual like behavior. Although women responded that the frequently used questions about bleeding and quality of life were important, they felt that the questions failed to go into enough depth to adequately characterize their experiences. Conclusions: Based on the themes identified in our focus group sessions, clinicians and researchers may need to change the questions used to capture “patient experience” with abnormal uterine bleeding more accurately.

In this article we describe the knowledge frameworks that 61 physicians, nurses, social workers, and psychologists from five public-sector health care facilities in Mexico used to conceptualize postpartum depression. We also demonstrate how providers applied social and behavioral antecedents in their conceptualizations of postpartum depression. Using grounded theory, we identify two frameworks that providers used to conceptualize postpartum depression: biochemical and adjustment. We highlight an emerging model of the function of social and behavioral antecedents within the frameworks, as well as the representation of postpartum depression by symptoms of distress and the perception among providers that these symptoms affected responsibilities associated with motherhood. The results provide a foundation for future study of how providers' conceptualizations of postpartum depression might affect detection and treatment practices and might be useful in the development of training materials to enhance the quality of care for women who experience any form of distress in the postpartum period. © The Author(s) 2014.

Risky sexual behavior: the indirect effects between parent-child relationship quality and quality of life in emerging adults.

Parent-child relationship quality is an important factor when examining adolescent's risk for problem behaviors. For this reason, many researchers have explored the impacts of parent-child relationship quality on adolescent and child behavior, yet the parent-child relationship has lasting consequences into adulthood. The current study examined the mediating role of risky sexual behavior (as measured by the Youth Risk Behavior Survey) on the relationship between parent-child relationship quality (as measured by the Parental Environment Questionnaire) and quality of life (as measured by the World Health Organizations Quality of Life Questionnaire) beyond adolescence, during emerging adulthood. The additional moderating effects of gender were examined. Participants consisted of 507 undergraduate students (173 males, 334 females) recruited from a large university in the Southern United States between 18 and 25 years of age. Parent-child relationship quality was positively related to quality of life among both males and females. The indirect pathway from parent-child relationship quality to quality of life, through risky sexual behavior, was significant in females but not in males. Results suggest that the parent-child relationship, specifically for females, may be a target for intervention in the prevention of risky sexual behavior in Emerging Adulthood. Further results, implications, and limitations were discussed.

Improved understanding of the searching behavior of ant colony optimization algorithms applied to the water distribution design problem

Evolutionary algorithms (EAs) have been applied successfully to many water resource problems, such as system design, management decision formulation, and model calibration. The performance of an EA with respect to a particular problem type is dependent on how effectively its internal operators balance the exploitation/exploration trade-off to iteratively find solutions of an increasing quality. For a given problem, different algorithms are observed to produce a variety of different final performances, but there have been surprisingly few investigations into characterizing how the different internal mechanisms alter the algorithm's searching behavior, in both the objective and decision space, to arrive at this final performance. This paper presents metrics for analyzing the searching behavior of ant colony optimization algorithms, a particular type of EA, for the optimal water distribution system design problem, which is a classical NP-hard problem in civil engineering. Using the proposed metrics, behavior is characterized in terms of three different attributes: (1) the effectiveness of the search in improving its solution quality and entering into optimal or near-optimal regions of the search space, (2) the extent to which the algorithm explores as it converges to solutions, and (3) the searching behavior with respect to the feasible and infeasible regions. A range of case studies is considered, where a number of ant colony optimization variants are applied to a selection of water distribution system optimization problems. The results demonstrate the utility of the proposed metrics to give greater insight into how the internal operators affect each algorithm's searching behavior.

Sleep quality is associated with different aspects of psychopathology, but relatively little research has examined links between sleep quality and externalizing behaviors or callous-unemotional traits. We examined: (1) whether an association exists between sleep quality and externalizing behaviors; (2) whether anxiety mediates this association; (3) whether callous-unemotional traits are associated with sleep quality. Data from two studies were used. Study 1 involved 1556 participants of the G1219 study aged 18-27 years (62% female). Questionnaire measures assessed sleep quality, anxiety, externalizing behaviors, and callous-unemotional traits. Study 2 involved 338 participants aged 18-66 years (65% female). Questionnaires measured sleep quality, externalizing behaviors, and callous-unemotional traits. In order to assess objective sleep quality, actigraphic data were also recorded for a week from a subsample of study 2 participants (n = 43). In study 1, poorer sleep quality was associated with greater externalizing behaviors. This association was partially mediated by anxiety and moderated by levels of callous-unemotional traits. There was no significant relationship between sleep quality and callous-unemotional traits. In study 2, poorer sleep quality, as assessed via self-reported but not objective measures, was associated with higher levels of externalizing behaviors. Furthermore, in study 2, better sleep quality (indicated in both questionnaires and actigraphy measures: lower mean activity, and greater sleep efficiency) was associated with higher levels of callous-unemotional traits. Self-reports of poorer sleep quality are associated with externalizing behaviors, and this association is partially mediated by anxiety. Callous-unemotional traits are not associated with poor sleep and may even be related to better sleep quality. This is an exceptional finding given that poor sleep quality appears to be a characteristic of most psychopathology. © Sleep Research Society 2017.

To test hypotheses from a horizontal violence and quality and safety of patient care model: horizontal violence (negative behavior among peers) is inversely related to peer relations, quality of care and it is positively related to errors and adverse events. Additionally, the association between horizontal violence, peer relations, quality of care, errors and adverse events, and nurse and work characteristics were determined. A random sample (n= 175) of hospital staff Registered Nurses working in California. Nurses participated via survey. Bivariate and multivariate analyses tested the study hypotheses. Hypotheses were supported. Horizontal violence was inversely related to peer relations and quality of care, and positively related to errors and adverse events. Including peer relations in the analyses altered the relationship between horizontal violence and quality of care but not between horizontal violence, errors and adverse events. Nurse and hospital characteristics were not related to other variables. Clinical area contributed significantly in predicting the quality of care, errors and adverse events but not peer relationships. Horizontal violence affects peer relationships and the quality and safety of patient care as perceived by participating nurses. Supportive peer relationships are important to mitigate the impact of horizontal violence on quality of care.

How does playing adapted sports affect quality of life of people with mobility limitations? Results from a mixed-method sequential explanatory study.

Occupations, including physical activity, are a strong determinant of health. However, mobility limitations can restrict opportunities to perform these occupations, which may affect quality of life. Some people will turn to adapted sports to meet their need to be involved in occupations. Little is known, however, about how participation in adapted sports affects the quality of life of people with mobility limitations. This study thus aimed to explore the influence of adapted sports on quality of life in adult wheelchair users. A mixed-method sequential explanatory design was used, including a quantitative and a qualitative component with a clinical research design. A total of 34 wheelchair users aged 18 to 62, who regularly played adapted sports, completed the Quality of Life Index (/30). Their scores were compared to those obtained by people of similar age without limitations (general population). Ten of the wheelchair users also participated in individual semi-structured interviews exploring their perceptions regarding how sports-related experiences affected their quality of life. The participants were 9 women and 25 men with paraplegia, the majority of whom worked and played an individual adapted sport (athletics, tennis or rugby) at the international or national level. People with mobility limitations who participated in adapted sports had a quality of life comparable to the group without limitations (21.9 ± 3.3 vs 22.3 ± 2.9 respectively), except for poorer family-related quality of life (21.0 ± 5.3 vs 24.1 ± 4.9 respectively). Based on the interviews, participants reported that the positive effect of adapted sports on the quality of life of people with mobility limitations operates mainly through the following: personal factors (behavior-related abilities and health), social participation (in general and through interpersonal relationships), and environmental factors (society's perceptions and support from the environment). Some contextual factors, such as resources and the accessibility of organizations and training facilities, are important and contributed indirectly to quality of life. Negative aspects, such as performance-related stress and injury, also have an effect. People with mobility limitations playing adapted sports and people without limitations have a similar quality of life. Participation in adapted sports was identified as having positive effects on self-esteem, self-efficacy, sense of belonging, participation in meaningful activities, society's attitude towards people with mobility limitations, and physical well-being. However, participants stated that this involvement, especially at higher levels, had a negative impact on their social life.

Health-related quality of life has been related to physical activity, sedentary behavior, and sleep among children from developed nations. These relationships have rarely been assessed in developing nations, nor have behaviors been considered in their true context, as mutually exclusive and exhaustive parts of the movement behavior composition. This study aimed to explore whether children's health-related quality of life is related to their movement behavior composition and if the relationship differs according to human development index. Children aged 9-11 years (n = 5855), from the 12-nation cross-sectional observational International Study of Childhood Obesity, Lifestyle and the Environment 2011-2013, self-reported their health-related quality of life (KIDSCREEN-10). Daily movement behaviors were from 24-h, 7-day accelerometry. Isometric log-ratio mixed-effect linear models were used to calculate estimates for difference in health-related quality of life for the reallocation of time between daily movement behaviors. Children from countries of higher human development index reported stronger positive relationships between health-related quality of life and moderate-to-vigorous physical activity, relative to the remaining behaviors (r = 0.75, p = 0.005) than those from lower human development index countries. In the very high human development index strata alone, health-related quality of life was significantly related to the movement behavior composition (p = 0.005), with moderate-to-vigorous physical activity (relative to remaining behaviors) being positively associated with health-related quality of life. The relationship between children's health-related quality of life and their movement behaviors is moderated by their country's human development index. This should be considered when 24-h movement behavior guidelines are developed for children around the world.

Until recently, research efforts were somewhat hampered by the lack of formal diagnostic criteria, which have now been codified as a category in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). Better characterization of deficits in socioemotional functioning caused by PMDD may aid in improving treatment efforts. Methods In this investigation, prospective symptom ratings, based on DSM-5 criteria, were used to measure PMDD symptoms in 36 women (18 with PMDD, 18 healthy controls). Two self-report inventories, the Emotion Regulation Questionnaire and the Difficulties in Emotion Regulation Scale, were used to measure ability to regulate emotions, and socioemotional functioning was measured by inventories of social connectedness, perceived stress, and affect. Potential relationships between ability to regulate emotion and PMDD symptom severity, as well as other measures of socioemotional functioning and affective state were tested. Results Women with PMDD reported significantly more behavioral impulsivity, and greater difficulties in regulating emotion and in socioemotional functioning. Conclusions Cognitive or behavioral strategies to improve these problems may benefit women with PMDD and help to alleviate distress caused by this disorder. PMID:27155663

Jealousy is a social emotion that has received little attention by developmental researchers. The current study examined sibling jealousy and its relations to child and family characteristics in 60 families with a 16-month-old toddler and an older preschool-age sibling. Sibling jealousy was elicited in social triads consisting of a parent (mother or father) and the two siblings. Positive marital relationship quality (i.e., love and relationship maintenance) was a particularly strong predictor of the older siblings' abilities to regulate jealousy reactions in the mother sessions. Younger siblings' jealous affect with mothers was linked to the child's temperament, whereas older siblings' jealous affect with mothers was related to the child's emotional understanding. Younger siblings displayed more behavioral dysregulation in the mother-sibling triads if there was greater sibling rivalry reported by mothers. Session order (i.e., which sibling was challenged first in the jealousy paradigm) had a strong effect on both the affect and behavioral dysregulation displayed by the older and younger siblings. Results are discussed with respect to the need for future research to consider social relationships as developmental contexts for young children's emotion regulation.

Management of Nursing Workplace Incivility in the Health Care Settings: A Systematic Review.

Armstrong, Nancy

2018-05-01

Workplace incivility is a well-documented issue in nursing in the health care setting. It has the potential to cause emotional and physical distress in victims and potentially affects the quality of care provided. The purpose of this study was to critique and summarize the most recent, available evidence related to interventions in assisting nursing staff working in health care settings in managing incivility. This systematic review of literature yielded 10 studies meeting the criteria. The studies were mostly identified as lower quality research. Despite the lower quality of research, the collection of evidence suggests the use of a combination of educational training about workplace incivility, training about effective responses to uncivil workplace behaviors, and active learning activities to practice newly learned communication skills, in assisting nurses in improving their ability to manage incivility in the workplace.

Intergenerational Efforts to Develop a Healthy Environment for Everyone: Sustainability as a Human Rights Issue.

As climate change proceeds at an unprecedented rate, concern for the natural environment has increased. The world's population aging also continues to rise at an unprecedented rate, giving greater attention to the implications of an older population. The two trends are linked through the fact that changes to the environment affect older adults, and older adults affect the environment. Sustainability is, therefore, an intergenerational phenomenon, and protecting resources today leaves a positive legacy and enhances quality of life for future generations. Older adults have much to share with younger generations about behaviors that promote sustainable living, yet few sustainability efforts are intergenerational in nature. As large numbers of people currently subsist without secure access to basic needs, ensuring equitable resource consumption for all generations is urgent and aligns with the Universal Declaration of Human Rights. Through exploring linkages between aging and sustainability, we identify intergenerational strategies to protect the environment and promote human rights and quality of life for older adults. © The Author(s) 2015.

Anxiety during pregnancy has been linked to adverse maternal health outcomes, including postpartum depression (PPD). However, there has been limited study of biological mechanisms underlying behavioral predictors of PPD during pregnancy. Considering the shared etiology of chronic stress amongst antenatal behavioral predictors, the primary goal of this pilot study was to examine associations among stress-related physiological factors (including GABA-ergic neurosteroids) and stress-related behavioral indices of anxiety during pregnancy. Fourteen nulliparous women in their second trimester of a singleton pregnancy underwent speech and mental arithmetic stress, following a 2-week subjective and objective recording of sleep-wake behavior. Lower cortisol, progesterone, and a combined measure of ALLO + pregnanolone throughout the entire stressor protocol (area under the curve, AUC) were associated with greater negative emotional responses to stress, and lower cortisol AUC was associated with worse sleep quality. Lower adrenocorticotropic hormone was associated with greater anxious and depressive symptoms. Stress produced paradoxical reductions in cortisol, progesterone, and a combined measure of allopregnanolone + pregnanolone, while tetrahydrodeoxycorticosterone levels were elevated. These data suggest that cortisol, progesterone, and ALLO + pregnanolone levels in the second trimester of pregnancy are inversely related to negative emotional symptoms, and the negative impact of acute stress challenge appears to exert its effects by reducing these steroids to further promote negative emotional responses.

This review examines evidence for psychological factors that affect pain across the cancer continuum from diagnosis through treatment and long-term survivorship or end of life. Evidence is convincing that emotional distress, depression, anxiety, uncertainty, and hopelessness interact with pain. Unrelieved pain can increase a desire for hastened death. Patients with cancer use many strategies to manage pain, with catastrophizing associated with increased pain and self-efficacy associated with lower pain reports. A variety of psychological and cognitive behavioral treatments can reduce pain severity and interference with function, as indicated in multiple meta-analyses and high-quality randomized controlled trials. Effective methods include education (with coping skills training), hypnosis, cognitive behavioral approaches, and relaxation with imagery. Exercise has been tested extensively in patients with cancer and long-term survivors, but few exercise studies have evaluated pain outcomes. In survivors post-treatment, yoga and hypnosis as well as exercise show promise for controlling pain. Although some of these treatments effectively reduce pain for patients with advanced disease, few have been tested in patients at the end of life. Given the clear indicators that psychological factors affect cancer pain and that psychological and behavioral treatments are effective in reducing varying types of pain for patients with active disease, these methods need further testing in cancer survivors post-treatment and in patients with end-stage disease. Multidisciplinary teams are essential in oncology settings to integrate analgesic care and expertise in psychological and behavioral interventions in standard care for symptom management, including pain.

This study examined hospital administrators' experiences with the National Practitioner Data Bank. One hundred forty-nine rural hospital administrators completed questionnaires assessing their perceptions of the data bank. Nearly 90% of respondents rated the data bank as an important source of information for credentialing. Three percent indicated it had directly affected privileging decisions; 43% and 34%, respectively, believed the costs exceeded or equaled the benefits. Twenty percent reported changes that could decrease disciplinary action reports to the data bank. While the National Practitioner Data Bank is an important source of information to rural hospitals, it may, affect few credentialing decisions and motivate behavioral changes that could have a paradoxical effect on quality assurance.

Trust Me, I’m a Doctor: Examining Changes in How Privacy Concerns Affect Patient Withholding Behavior

2017-01-01

Background As electronic health records (EHRs) become ubiquitous in the health care industry, privacy breaches are increasing and being made public. These breaches may make consumers wary of the technology, undermining its potential to improve care coordination and research. Objective Given the developing concerns around privacy of personal health information stored in digital format, it is important for providers to understand how views on privacy and security may be associated with patient disclosure of health information. This study aimed to understand how privacy concerns may be shifting patient behavior. Methods Using a pooled cross-section of data from the 2011 and 2014 cycles of the Health Information and National Trends Survey (HINTS), we tested whether privacy and security concerns, as well as quality perceptions, are associated with the likelihood of withholding personal health information from a provider. A fully interacted multivariate model was used to compare associations between the 2 years, and interaction terms were used to evaluate trends in the factors that are associated with withholding behavior. Results No difference was found regarding the effect of privacy and security concerns on withholding behavior between 2011 and 2014. Similarly, whereas perceived high quality of care was found to reduce the likelihood of withholding information from a provider in both 2011 (odds ratio [OR] 0.73, 95% confidence interval [CI] 0.56-0.94) and 2014 (OR 0.61, 95% CI 0.48-0.76), no difference was observed between years. Conclusions These findings suggest that consumers’ beliefs about EHR privacy and security, the relationship between technology use and quality, and intentions to share information with their health care provider have not changed. These findings are counter to the ongoing discussions about the implications of security failures in other domains. Our results suggest that providers could ameliorate privacy and security by focusing on the care quality benefits EHRs provide. PMID:28052843

Positive affect: phenotypic and etiologic associations with prosocial behaviors and internalizing problems in toddlers

Despite evidence for the associations of positive affect to prosocial behaviors and internalizing problems, relatively little is known about the underlying etiology. The sample comprised over 300 twin pairs at age 3. Positive affect, prosocial behaviors, and internalizing problems were assessed using the Toddler Behavior Assessment Questionnaire (Goldsmith, 1996), the Revised Rutter Parent Scale for Preschool Children (Hogg et al., 1997), and the Child Behavior Checklist for ages 1.5–5 (Achenbach, 1991), respectively. Positive affect correlated positively with prosocial behaviors, and negatively with internalizing problems. Prosocial behaviors were negatively associated with internalizing problems. The relations of positive affect to prosocial behaviors and internalizing problems were due to environmental effects (shared and non-shared). In contrast, the link between prosocial behaviors and internalizing problems was entirely explained by genetic effects. The current study has moved beyond prior emphasis on negative affect and elucidated the less understood etiology underlying the associations between positive affect, prosocial behaviors, and internalizing problems. This study could guide the development of programs for promoting prosocial behaviors and alleviating internalizing problems in children. PMID:25914668

Metal contamination at low levels is an important issue because it usually produces health and environmental effects, either positive or deleterious. Contamination of surface waters with copper (Cu) is a worldwide event, usually originated by mining, agricultural, industrial, commercial, and residential activities. Water quality criteria for Cu are variable among countries but allowed limits are generally in the μg/L range, which can disrupt several functions in the early life-stages of fish species. Behavioral and biochemical alterations after Cu exposure have also been described at concentrations close to the allowed limits. Aiming to search for the effects of Cu in the range of the allowed limits, larvae and adult zebrafish (Danio rerio) were exposed to different concentrations of dissolved Cu (nominally: 0, 5, 9, 20 and 60μg/L; measured: 0.4, 5.7, 7.2 16.6 and 42.3μg/L, respectively) for 96h. Larvae swimming and body length, and adult behavior and biochemical biomarkers (activity of glutathione-related enzymes in gills, muscle, and brain) were assessed after Cu exposure. Several effects were observed in fish exposed to 9μg/L nominal Cu, including increased larvae swimming distance and velocity, abolishment of adult inhibitory avoidance memory, and decreased glutathione S-transferase (GST) activity in gills of adult fish. At the highest Cu concentration tested (nominally: 60μg/L), body length of larvae, spatial memory of adults, and gill GST activity were decreased. Social behavior (aggressiveness and conspecific interaction), and glutathione reductase (GR) activity were not affected in adult zebrafish. Exposure to Cu, at concentrations close to the water quality criteria for this metal in fresh water, was able to alter larvae swimming performance and to induce detrimental effects on the behavior of adult zebrafish, thus indicating the need for further studies to reevaluate the currently allowed limits for Cu in fresh water.

Intermittent Water Supply: Prevalence, Practice, and Microbial Water Quality.

Kumpel, Emily; Nelson, Kara L

2016-01-19

Intermittent water supplies (IWS), in which water is provided through pipes for only limited durations, serve at least 300 million people around the world. However, providing water intermittently can compromise water quality in the distribution system. In IWS systems, the pipes do not supply water for periods of time, supply periods are shortened, and pipes experience regular flow restarting and draining. These unique behaviors affect distribution system water quality in ways that are different than during normal operations in continuous water supplies (CWS). A better understanding of the influence of IWS on mechanisms causing contamination can help lead to incremental steps that protect water quality and minimize health risks. This review examines the status and nature of IWS practices throughout the world, the evidence of the effect of IWS on water quality, and how the typical contexts in which IWS systems often exist-low-income countries with under-resourced utilities and inadequate sanitation infrastructure-can exacerbate mechanisms causing contamination. We then highlight knowledge gaps for further research to improve our understanding of water quality in IWS.

Protein quality relies not only on total protein but also on protein inherent structures. The most commonly occurring protein secondary structures (α-helix and β-sheet) may influence protein quality, nutrient utilization, and digestive behavior. The objectives of this study were to reveal the protein molecular structures of canola meal (yellow and brown) and presscake as affected by the heat-processing methods and to investigate the relationship between structure changes and protein rumen degradations kinetics, estimated protein intestinal digestibility, degraded protein balance, and metabolizable protein. Heat-processing conditions resulted in a higher value for α-helix and β-sheet for brown canola presscake compared to brown canola meal. The multivariate molecular spectral analyses (PCA, CLA) showed that there were significant molecular structural differences in the protein amide I and II fingerprint region (ca. 1700-1480 cm(-1)) between the brown canola meal and presscake. The in situ degradation parameters, amide I and II, and α-helix to β-sheet ratio (R_a_β) were positively correlated with the degradable fraction and the degradation rate. Modeling results showed that α-helix was positively correlated with the truly absorbed rumen synthesized microbial protein in the small intestine when using both the Dutch DVE/OEB system and the NRC-2001 model. Concerning the protein profiles, R_a_β was a better predictor for crude protein (79%) and for neutral detergent insoluble crude protein (68%). In conclusion, ATR-FT/IR molecular spectroscopy may be used to rapidly characterize feed structures at the molecular level and also as a potential predictor of feed functionality, digestive behavior, and nutrient utilization of canola feed.

Linking Foraging Decisions to Residential Yard Bird Composition

Urban bird communities have higher densities but lower diversity compared with wildlands. However, recent studies show that residential urban yards with native plantings have higher native bird diversity compared with yards with exotic vegetation. Here we tested whether landscape designs also affect bird foraging behavior. We estimated foraging decisions by measuring the giving-up densities (GUD; amount of food resources remaining when the final forager quits foraging on an artificial food patch, i.e seed trays) in residential yards in Phoenix, AZ, USA. We assessed how two yard designs (mesic: lush, exotic vegetation; xeric: drought-tolerant and native vegetation) differed in foraging costs. Further, we developed a statistical model to calculate GUDs for every species visiting the seed tray. Birds foraging in mesic yards depleted seed trays to a lower level (i.e. had lower GUDs) compared to birds foraging in xeric yards. After accounting for bird densities, the lower GUDs in mesic yards appeared largely driven by invasive and synanthropic species. Furthermore, behavioral responses of individual species were affected by yard design. Species visiting trays in both yard designs had lower GUDs in mesic yards. Differences in resource abundance (i.e., alternative resources more abundant and of higher quality in xeric yards) contributed to our results, while predation costs associated with foraging did not. By enhancing the GUD, a common method for assessing the costs associated with foraging, our statistical model provided insights into how individual species and bird densities influenced the GUD. These differences we found in foraging behavior were indicative of differences in habitat quality, and thus our study lends additional support for native landscapes to help reverse the loss of urban bird diversity.

Olfactory loss is known to affect both mood and quality of life. Transient anosmia was induced in mice to study the resulting changes in mood, behavior, and on a molecular level. Transient anosmia was induced by a single intranasal instillation of ZnSO4 in BALB/c mice. Hematoxylin and eosin (HE) staining, and potato chip finding test were performed to confirm olfactory loss. Tail suspension, forced swim, and splash tests were performed to evaluate depression-related behavior; while the open field, and elevated plus maze tests were used to evaluate anxiety-related behavior. The mRNA levels of amygdalar corticotropin-releasing hormone (CRH) and hypothalamic glucocorticoid receptor (GR) were quantified using real-time PCR to confirm relevant molecular change. Olfactory loss was confirmed 1-2.5 weeks after induction, and this loss was subsequently reversed over time. The results of the behavioral tests indicated increased depression-like and reduced anxiety-like behavior at week 1. Accordingly, PCR data identified decreased amygdalar CRH expression at week 1. These results suggest that transient anosmia induces both depressive and anxiolytic behavior as a result of decreased amygdalar CRH in a mouse model of anosmia.

Effect of Using an Indoor Air Quality Sensor on Perceptions of and Behaviors Toward Air Pollution (Pittsburgh Empowerment Library Study): Online Survey and Interviews

Background Air quality affects us all and is a rapidly growing concern in the 21st century. We spend the majority of our lives indoors and can be exposed to a number of pollutants smaller than 2.5 microns (particulate matter, PM2.5) resulting in detrimental health effects. Indoor air quality sensors have the potential to provide people with the information they need to understand their risk and take steps to reduce their exposure. One such sensor is the Speck sensor developed at the Community Robotics, Education and Technology Empowerment Lab at Carnegie Mellon University. This sensor provides users with continuous real-time and historical PM2.5 information, a Web-based platform where people can track their PM2.5 levels over time and learn about ways to reduce their exposure, and a venue (blog post) for the user community to exchange information. Little is known about how the use of such monitors affects people’s knowledge, attitudes, and behaviors with respect to indoor air pollution. Objective The aim of this study was to assess whether using the sensor changes what people know and do about indoor air pollution. Methods We conducted 2 studies. In the first study, we recruited 276 Pittsburgh residents online and through local branches of the Carnegie Library of Pittsburgh, where the Speck sensor was made available by the researchers in the library catalog. Participants completed a 10- to 15-min survey on air pollution knowledge (its health impact, sources, and mitigation options), perceptions of indoor air quality, confidence in mitigation, current behaviors toward air quality, and personal empowerment and creativity in the spring and summer of 2016. In our second study, we surveyed 26 Pittsburgh residents in summer 2016 who checked out the Speck sensor for 3 weeks on the same measures assessed in the first study, with additional questions about the perception and use of the sensor. Follow-up interviews were conducted with a subset of those who used the Speck sensor. Results A series of paired t tests found participants were significantly more knowledgeable (t25=−2.61, P=.02), reported having significantly better indoor air quality (t25=−5.20, P<.001), and felt more confident about knowing how to mitigate their risk (t25=−1.87, P=.07) after using the Speck sensor than before. McNemar test showed participants tended to take more action to reduce indoor air pollution after using the sensor (χ225=2.7, P=.10). Qualitative analysis suggested possible ripple effects of use, including encouraging family and friends to learn about indoor air pollution. Conclusions Providing people with low- or no-cost portable indoor air quality monitors, with a supporting Web-based platform that offers information about how to reduce risk, can help people better express perceptions and adopt behaviors commensurate with the risks they face. Thus, thoughtfully designed and deployed personal sensing devices can help empower people to take steps to reduce their risk. PMID:29519779

Effects of aging, word frequency, and text stimulus quality on reading across the adult lifespan: Evidence from eye movements.

PubMed

Warrington, Kayleigh L; McGowan, Victoria A; Paterson, Kevin B; White, Sarah J

2018-04-19

Reductions in stimulus quality may disrupt the reading performance of older adults more when compared with young adults because of sensory declines that begin early in middle age. However, few studies have investigated adult age differences in the effects of stimulus quality on reading, and none have examined how this affects lexical processing and eye movement control. Accordingly, we report two experiments that examine the effects of reduced stimulus quality on the eye movements of young (18-24 years), middle-aged (41-51 years), and older (65+ years) adult readers. In Experiment 1, participants read sentences that contained a high- or low-frequency critical word and that were presented normally or with contrast reduced so that words appeared faint. Experiment 2 further investigated effects of reduced stimulus quality using a gaze-contingent technique to present upcoming text normally or with contrast reduced. Typical patterns of age-related reading difficulty (e.g., slower reading, more regressions) were observed in both experiments. In addition, eye movements were disrupted more for older than younger adults when all text (Experiment 1) or just upcoming text (Experiment 2) appeared faint. Moreover, there was an interaction between stimulus quality and word frequency (Experiment 1), such that readers fixated faint low-frequency words for disproportionately longer. Crucially, this effect was similar across all age groups. Thus, although older readers suffer more from reduced stimulus quality, this additional difficulty primarily affects their visual processing of text. These findings have important implications for understanding the role of stimulus quality on reading behavior across the lifespan. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Ample studies have established that parents as well as peers function as role models in the development of adolescents' alcohol use. The role of siblings, however, has been largely neglected despite the long-term nature of a sibling relationship. The present study examined the impact of siblings on drinking behavior of adolescents using longitudinal data from 416 sibling dyads. Moreover, we explored which factors (gender constellation of the sibling dyad, quality of the sibling relationship, and similarity in norms about alcohol) affect reciprocal influences in alcohol use of siblings. Descriptive analyses showed that although older siblings drink more frequently and intensively than the younger siblings, moderate associations were found between frequency and intensity of drinking in siblings. Findings of structural equation modeling demonstrated that alcohol use of the older sibling marginally affected drinking of the younger sibling one year later. Drinking of the younger sibling did not affect drinking of the older sibling. Further, we found no moderating effects of having the same or opposite gender as a sibling, a low or high quality relationship, and the same or different norms about alcohol, on the association between siblings' alcohol use and adolescents' drinking over time.

"Just Take a Moment and Breathe and Think": Young Women with Depression Talk about the Development of an Ecological Momentary Intervention to Reduce Their Sexual Risk.

Depressed young women are at increased risk for adverse outcomes related to sexual behavior, including unintended pregnancy, HIV, and other sexually transmitted infections. Brief sexual risk reduction interventions have not targeted depressed young women's specific needs for affect management and impulse control. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: We interviewed depressed young women ages 15-23 years engaging in sexual risk behavior about a proposed intervention approach. The approach was described as in-person counseling and cognitive-behavioral skills training, followed by an ecological momentary intervention (EMI) delivered via smartphone application for 4 weeks. The EMI would include reporting multiple times a day on affective states, self-efficacy for safer sex behavior, and sexual behavior, and receiving responsive messages to provide support and prompt use of cognitive-behavioral skills. Participants provided their perspectives on comfort, usability, burden, confidentiality, and potential efficacy of the EMI and recommended message content. Interviews were audio-recorded, transcribed, and analyzed using thematic analysis. Thematic saturation was reached with 16 interviews. Participants expressed positive opinions about the EMI. They believed that reporting at random times would help them to recognize their feelings, receiving the messages would be reassuring, and overall the smartphone application would be experienced as therapeutic. They desired a high degree of personalization of the message quality, style, and voice, and provided a wide variety of message content.

Positive social behavior of student is an important factor in the integrity of educational quality. Unbalanced behavior can disrupt the progress of students in learning. The present study evaluates the effect of social factors on education quality of dental and medical students. This descriptive cross-sectional study was conducted on 227 randomly selected students (109 dental and 118 medical). The questionnaire contained three domains of cultural collectivism, self-concept, and social adjustment adapted from California Test of Personality. It also included demographic questions like; field of study, gender and home city of residence. Data was analyzed using SPSS (version#19) software. Pearsons' correlation coefficient and independent t-test were used at the P-value of 0.05. Generally, girl students showed higher cultural collectivism (P=0.028) and social adjustment (P=0.04). On the contrary, boys were better in self-concept behavior (P=0.34). Home city of residence evidenced with no significant effect on any aspects of social attitudes of subjects. Pearsons' correlation coefficient test showed a weak correlation between cultural collectivism and self-concept (r=0.134, P=0.04) and between cultural collectivism and social adjustment, as well. (r=0.252, P=0.001) Independent t-test showed a significant difference between male and female students concerning cultural collectivism and social adjustment. Reliability of cultural collectivism, self-concept and social adjustment scales ranged from very good to moderate, α=0.83, α=0.63, and α=0.54 respectively. The results of this study indicated that female students show better cultural collectivism and social adjustment skills. It also proved that home city of residence has no significant effect upon social behavior of either medical or dental students.

An electrical power systems are exposed to different types of power quality disturbances. Investigation and monitoring of power quality are necessary to maintain accurate operation of sensitive equipment especially for nuclear installations. This paper will discuss the power quality problems observed at the electrical sources of PUSPATI TRIGA Reactor (RTP). Assessment of power quality requires the identification of any anomalous behavior on a power system, which adversely affects the normal operation of electrical or electronic equipment. A power quality assessment involves gathering data resources; analyzing the data (with reference to power quality standards) then, if problems exist, recommendation of mitigation techniques must be considered. Field power quality data is collected by power quality recorder and analyzed with reference to power quality standards. Normally the electrical power is supplied to the RTP via two sources in order to keep a good reliability where each of them is designed to carry the full load. The assessment of power quality during reactor operation was performed for both electrical sources. There were several disturbances such as voltage harmonics and flicker that exceeded the thresholds. To reduce these disturbances, mitigation techniques have been proposed, such as to install passive harmonic filters to reduce harmonic distortion, dynamic voltage restorer (DVR) to reduce voltage disturbances and isolate all sensitive and critical loads.

Integrated environmental modeling (IEM) can organize and increase our knowledge of the complex, dynamic ecosystems that house our natural resources and control the quality of our environments. Human behavior, however, must be taken into account. Human biases/heuristics reflect adaptation over our evolutionary past to frequently experienced situations that affected our survival and that provided sharply distinguished feedbacks at the level of the individual. Unfortunately, human behavior is not adapted to the more diffusely experienced, less frequently encountered, problems and issues that IEM typically seeks to address in the simulation of natural resources and environments. While seeking inspiration from the prophetic traditions of the Oracle of Delphi, several human biases are identified that may affect how the science base of IEM is assembled, and how IEM results are interpreted and used. These biases are supported by personal observations, and by the findings of behavioral scientists. A process for critical analysis is proposed that solicits explicit accounting and cognizance of potential human biases. A number of suggestions are made to address the human challenges of IEM, in addition to maintaining attitudes of watchful humility, open-mindedness, honesty, and transparent accountability. These include creating a new area of study in the behavioral biogeosciences, using structured processes for engaging the modeling and stakeholder community in IEM, and using “red teams” to increase resilience of IEM constructs and use.

In young children with type 1 diabetes mellitus (T1DM), parents have complete responsibility for the diabetes-management. In toddlers and (pre)schoolers, the tasks needed to achieve optimal blood glucose control may interfere with normal developmental processes and could negatively affect the quality of parent-child interaction. Several observational instruments are available to measure the quality of the parent-child interaction. However, no observational instrument for diabetes-specific situations is available. Therefore, the aim of the present study was to develop a qualitative observation instrument, to be able to assess parent-child interaction during diabetes-specific situations. First, in a pilot study (n = 15), the observation instrument was developed in four steps: (a) defining relevant diabetes-specific situations; (b) videotaping these situations; (c) describing all behaviors in a qualitative observation instrument; (d) evaluating usability and reliability. Next, we examined preliminary validity (total n = 77) by testing hypotheses about correlations between the observation instrument for diabetes-specific situations, a generic observation instrument and a behavioral questionnaire. The observation instrument to assess parent-child interaction during diabetes-specific situations, which consists of ten domains: "emotional involvement", "limit setting", "respect for autonomy", "quality of instruction", "negative behavior", "avoidance", "cooperative behavior", "child's response to injection", "emphasis on diabetes", and "mealtime structure", was developed for use during a mealtime situation (including glucose monitoring and insulin administration). The present study showed encouraging indications for the usability and inter-rater reliability (weighted kappa was 0.73) of the qualitative observation instrument. Furthermore, promising indications for the preliminary validity of the observation instrument for diabetes-specific situations were found (r ranged between |.24| and |.45| for significant correlations and between |.10| and |.23| for non-significant trends). This observation instrument could be used in future research to (a) test whether parent-child interactions are associated with outcomes (like HbA1c levels and psychosocial functioning), and (b) evaluate interventions, aimed at optimizing the quality of parent-child interactions in families with a young child with T1DM.

Is Empathic Accuracy Enough to Facilitate Responsive Behavior in Dyadic Interaction? Distinguishing Ability From Motivation.

Growing evidence suggests that interpersonal responsiveness-feeling understood, validated, and cared for by other people-plays a key role in shaping the quality of one's social interactions and relationships. But what enables people to be interpersonally responsive to others? In the current study, we argued that responsiveness requires not only accurate understanding but also compassionate motivation. Specifically, we hypothesized that understanding another person's thoughts and feelings (empathic accuracy) would foster responsive behavior only when paired with benevolent motivation (empathic concern). To test this idea, we asked couples (N = 91) to discuss a personal or relationship stressor; we then assessed empathic accuracy, empathic concern, and responsive behavior. As predicted, when listeners' empathic concern was high, empathic accuracy facilitated responsiveness; but when empathic concern was low, empathic accuracy was unhelpful (and possibly harmful) for responsiveness. These findings provide the first evidence that cognitive and affective forms of empathy work together to facilitate responsive behavior. © The Author(s) 2016.

HIGHLIGHTS Psychological stress activates neuroendocrine pathways that alter immune responses.Stress-induced alterations in microglia phenotype and monocyte priming leads to aberrant peripheral and central inflammation.Elevated pro-inflammatory cytokine levels caused by microglia activation and recruitment of monocytes to the brain contribute to development and persistent anxiety-like behavior.Mechanisms that mediate interactions between microglia, endothelial cells, and macrophages and how these contribute to changes in behavior are discussed.Sensitization of microglia and re-distribution of primed monocytes are implicated in re-establishment of anxiety-like behavior. Psychological stress causes physiological, immunological, and behavioral alterations in humans and rodents that can be maladaptive and negatively affect quality of life. Several lines of evidence indicate that psychological stress disrupts key functional interactions between the immune system and brain that ultimately affects mood and behavior. For example, activation of microglia, the resident innate immune cells of the brain, has been implicated as a key regulator of mood and behavior in the context of prolonged exposure to psychological stress. Emerging evidence implicates a novel neuroimmune circuit involving microglia activation and sympathetic outflow to the peripheral immune system that further reinforces stress-related behaviors by facilitating the recruitment of inflammatory monocytes to the brain. Evidence from various rodent models, including repeated social defeat (RSD), revealed that trafficking of monocytes to the brain promoted the establishment of anxiety-like behaviors following prolonged stress exposure. In addition, new evidence implicates monocyte trafficking from the spleen to the brain as key regulator of recurring anxiety following exposure to prolonged stress. The purpose of this review is to discuss mechanisms that cause stress-induced monocyte re-distribution in the brain and how dynamic interactions between microglia, endothelial cells, and brain macrophages lead to maladaptive behavioral responses.

General movement (GM) assessment is a well-established tool to predict cerebral palsy in high-risk infants. Little is known on the predictive value of GM assessment in low-risk populations. To assess the predictive value of GM quality in early infancy for the development of the clinically relevant form of minor neurological dysfunction (complex MND) and behavioral problems at preschool age. Prospective cohort study. A total of 216 members of the prospective Groningen Assisted Reproductive Techniques (ART) cohort study were included in this study. ART did not affect neurodevelopmental outcome of these relatively low-risk infants born to subfertile parents. GM quality was determined at 2 weeks and 3 months. At 18 months and 4 years, the Hempel neurological examination was used to assess MND. At 4 years, parents completed the Child Behavior Checklist; this resulted in the total problem score (TPS), internalizing problem score (IPS), and externalizing problem score (EPS). Predictive values of definitely (DA) and mildly (MA) abnormal GMs were calculated. DA GMs at 2 weeks were associated with complex MND at 18 months and atypical TPS and IPS at 4 years (all p<0.05). Sensitivity and positive predictive value of DA GMs at 2 weeks were rather low (13%-60%); specificity and negative predictive value were excellent (92%-99%). DA GMs at 3 months occurred too infrequently to calculate prediction. MA GMs were not associated with outcome. GM quality as a single predictor for complex MND and behavioral problems at preschool age has limited clinical value in children at low risk for developmental disorders.

During wheat milling, starch granules can experience mechanical damage, producing damaged starch. High levels of damaged starch modify the physicochemical properties of wheat flour, negatively affecting the dough behavior as well as the flour quality and cookie and bread making quality. The aim of this work was to evaluate the effect of α-amylase, maltogenic amylase and amyloglucosidase on dough rheology in order to propose alternatives to reduce the issues related to high levels of damaged starch. The dough with a high level of damaged starch became more viscous and resistant to deformations as well as less elastic and extensible. The soluble fraction of the doughs influenced the rheological behavior of the systems. The α-amylase and amyloglucosidase reduced the negative effects of high damaged starch contents, improving the dough rheological properties modified by damaged starch. The rheological behavior of dough with the higher damaged-starch content was related to a more open gluten network arrangement as a result of the large size of the swollen damaged starch granules. We can conclude that the dough rheological properties of systems with high damaged starch content changed positively as a result of enzyme action, particularly α-amylase and amyloglucosidase additions, allowing the use of these amylases and mixtures of them as corrective additives. Little information was reported about amyloglucosidase activity alone or combined with α-amylase. The combinations of these two enzymes are promising to minimize the negative effects caused by high levels of damaged starch on product quality. More research needs to be done on bread quality combining these two enzymes. © 2015 Society of Chemical Industry. © 2015 Society of Chemical Industry.

Health-related quality of life (HRQOL) among kidney transplant recipients is associated with physical and psychosocial characteristics. Furthermore, pregnancy and childcare may be particularly challenging for women. The aim of this study was to assess the relationship between patients' psychosocial characteristics and HRQOL, specifically for recipients who have given birth after their kidney transplant. This was a cross-sectional study. Participants were 59 kidney transplant recipients who had given birth after transplantation. The tools used were the Medical Outcomes Scale, the Kidney Transplantation Self-Management Scale, the Multidimensional Scale of Perceived Social Support (MSPSS), and The Maternal Consciousness Scale. Mean age was 42.3±7.2 years, and the mean age at the time of transplant was 28.2±4.6 years. A total of 82 fetal outcomes were evaluated. Maternal age was 33.6±4.1 years, duration of gestational period was 35.3±3.3 weeks, and birth weight was 2,303.8±592.5 g. HRQOL results were nearly the same as stratified national norms. The physical component summary was positively correlated with the MSPSS ( p =0.025), and self-care behavior was positively correlated with the mental component score ( p =0.029) and MSPSS ( p =0.016). A structural equation model revealed that self-care behavior and the patient-health professions partnership indirectly affected physical health through social support. Self-management indirectly affects physical health through social support. To create a supportive environment through monitoring and consultation with patient families, child-rearing kidney transplant recipients should be encouraged to improve their self-management skills to improve their quality of life. Social support for self-management may contribute to improve HRQOL for women who experience pregnancy and child-rearing after transplantation.

We report the current best estimate of the effects of cognitive behavior therapy (CBT) in the treatment of major depression (MDD), generalized anxiety disorder (GAD), panic disorder (PAD) and social anxiety disorder (SAD), taking into account publication bias, the quality of trials, and the influence of waiting list control groups on the outcomes. In our meta‐analyses, we included randomized trials comparing CBT with a control condition (waiting list, care‐as‐usual or pill placebo) in the acute treatment of MDD, GAD, PAD or SAD, diagnosed on the basis of a structured interview. We found that the overall effects in the 144 included trials (184 comparisons) for all four disorders were large, ranging from g=0.75 for MDD to g=0.80 for GAD, g=0.81 for PAD, and g=0.88 for SAD. Publication bias mostly affected the outcomes of CBT in GAD (adjusted g=0.59) and MDD (adjusted g=0.65), but not those in PAD and SAD. Only 17.4% of the included trials were considered to be high‐quality, and this mostly affected the outcomes for PAD (g=0.61) and SAD (g=0.76). More than 80% of trials in anxiety disorders used waiting list control groups, and the few studies using other control groups pointed at much smaller effect sizes for CBT. We conclude that CBT is probably effective in the treatment of MDD, GAD, PAD and SAD; that the effects are large when the control condition is waiting list, but small to moderate when it is care‐as‐usual or pill placebo; and that, because of the small number of high‐quality trials, these effects are still uncertain and should be considered with caution.

Poor social functioning is associated with cognitive decline in older adults. It is unclear whether social functioning is also associated with subjective memory complaints (SMC). We investigated the association between social functioning and incident SMC and SMC recovery. A population-based sample of 8762 older adults (aged ≥65 years) with good objective cognitive functioning at baseline (MMSE ≥26) from the LifeLines Cohort Study were followed for 1.5 years. Self-reported SMC were measured at baseline and after 1.5 years follow-up. Aspects of social functioning included marital status, household composition, social network size, social activity, quality of social relationships, social support, affection, behavioral confirmation, and status. Thirteen percent (513/3963) developed SMC during follow-up (incident SMC). Multivariate logistic regression analyses (adjusted for age, gender, education level, physical activity, alcohol use, smoking status, depression, arrhythmia, myocardial infarction, heart failure, stroke) showed that participants with better feelings of affection, behavioral confirmation and stable good social support had a lower risk of incident SMC. Thirty-four percent (1632/4799) reported recovery. Participants with good social functioning at baseline on all determinants reported more SMC recovery. People who remained stable in a relationship, stable in good quality of social relationships or increased in quality of social relationships more often report SMC recovery. Good social functioning is associated with less incident SMC and more SMC recovery over a follow-up period of 1.5 years. Albeit future confirmative studies are needed, we argue for targeting also social functioning when designing multidomain interventions to prevent or slow down cognitive decline.

Externalizing symptoms, effortful control, and intrusive parenting: A test of bidirectional longitudinal relations during early childhood.

2015-11-01

At approximately 30, 42, and 54 months of age (N = 231), the relations among children's externalizing symptoms, intrusive maternal parenting, and children's effortful control (EC) were examined. Both intrusive parenting and low EC have been related to psychopathology, but children's externalizing problems and low EC might affect the quality of parenting and one another. Mothers' intrusive behavior with their children was assessed with observations, children's EC was measured with mothers' and caregivers' reports, and children's externalizing symptoms were assessed with mothers', fathers', and caregivers' reports. In a structural equation panel model, bidirectional relations between intrusive parenting and EC were found: EC at 30 and 42 months predicted low levels of intrusive parenting a year later, controlling for prior levels of parenting and vice versa. Moreover, high levels of children's externalizing problems at both 30 and 42 months negatively predicted EC a year later, controlling for prior levels of EC. Although externalizing problems positively predicted high EC over time, this appeared to be a suppression effect because these variables had a strong negative pattern in the zero-order correlations. Moreover, when controlling for the stability of intrusive parenting, EC, and externalizing (all exhibited significant stability across time) and the aforementioned cross-lagged predictive paths, EC and externalizing problems were still negatively related within the 54-month assessment. The findings are consistent with the view that children's externalizing behavior undermines their EC and contributes to intrusive mothering and that relations between intrusive parenting and EC are bidirectional across time. Thus, interventions that focus on modifying children's externalizing problems (as well as the quality of parenting) might affect the quality of parenting they receive and, hence, subsequent problems with adjustment.

Why Acting Environmentally-Friendly Feels Good: Exploring the Role of Self-Image

Venhoeven, Leonie A.; Bolderdijk, Jan Willem; Steg, Linda

2016-01-01

Recent research suggests that engagement in environmentally-friendly behavior can feel good. Current explanations for such a link do not focus on the nature of environmentally-friendly behavior itself, but rather propose well-being is more or less a side-benefit; behaviors that benefit environmental quality (e.g., spending one's money on people rather than products) also tend to make us feel good. We propose that the moral nature of environmentally-friendly behavior itself may elicit positive emotions as well, because engaging in this behavior can signal one is an environmentally-friendly and thus a good person. Our results show that engagement in environmentally-friendly behavior can indeed affect how people see themselves: participants saw themselves as being more environmentally-friendly when they engaged in more environmentally-friendly behavior (Study 1). Furthermore, environmentally-friendly behavior resulted in a more positive self-image, more strongly when it was voluntarily engaged in, compared to when it was driven by situational constraints (Study 2). In turn, the more environmentally-friendly (Study 1) and positive (Study 2) people saw themselves, the better they felt about acting environmentally-friendly. Together, these results suggest that the specific self-signal that ensues from engaging in environmentally-friendly behavior can explain why environmentally-friendly actions may elicit a good feeling.

Obesity is a public health problem that disproportionately affects low-income populations. Moreover, participation in Supplemental Nutrition Assistance Program (SNAP) has been associated with obesity among low-income women. The goal of this study was to determine the impact of intrapersonal, home environment, community and social factors on diet quality and body mass index (BMI) of low-income women participating in SNAP. This study also aimed to examine the role of these factors in mediating the relationship between food insecurity and diet quality, and BMI. A total of 152 women receiving SNAP benefits were recruited from low-income neighborhood centers and housing communities, and administered a demographics questionnaire, the United States adult food security scale, food frequency questionnaire, and multi-dimensional home environment scale (MHES). They also were measured for height and weight to calculate BMI. The Dietary Guidelines Adherence Index 2015 was used to measure diet quality. Regression analyses were conducted to determine the MHES subscales that were significant predictors of diet quality and BMI. The Preacher and Hayes mediation model was used to evaluate the mediation of the relationship between food insecurity and diet quality, and BMI by the MHES. Emotional eating resistance and favorable social eating behaviors were positively associated with diet quality; whereas emotional eating resistance, lower availability of unhealthy food at home, neighborhood safety and favorable social eating behaviors were inversely associated with BMI in women participating in SNAP. The MHES significantly mediated the relationship between food insecurity and BMI. These results emphasize the importance of intrapersonal, home environment, community and social factors in mediating the relationship between food insecurity and BMI in low-income women.

The structure-process-outcome quality framework espoused by Donabedian provides a conceptual way to examine and prioritize behavioral health quality measures used by states. This report presents an environmental scan of the quality measures and satisfaction surveys that state Medicaid managed care and behavioral health agencies used prior to Medicaid expansion in 2014. Data were collected by reviewing online documents related to Medicaid managed care contracts for behavioral health, quality strategies, quality improvement plans, quality and performance indicators data, annual outcomes reports, performance measure specification manuals, legislative reports, and Medicaid waiver requests for proposals. Information was publicly available for 29 states. Most states relied on process measures, along with some structure and outcome measures. Although all states reported on at least one process measure of behavioral health quality, 52% of states did not use any outcomes measures and 48% of states had no structure measures. A majority of the states (69%) used behavioral health measures from the National Committee for Quality Assurance's Healthcare Effectiveness Data and Information Set, and all but one state in the sample (97%) used consumer experience-of-care surveys. Many states supplemented these data with locally developed behavioral health indicators that rely on administrative and nonadministrative data. State Medicaid agencies are using nationally recognized as well as local measures to assess quality of behavioral health care. Findings indicate a need for additional nationally endorsed measures in the area of substance use disorders and treatment outcomes.

Evolutionary theory was applied to Reeder and Brewer's schematic theory and Trafimow's affect theory to extend this area of research with five new predictions involving affect and ability attributions, comparing morality and ability attributions, gender differences, and reaction times for affect and attribution ratings. The design included a 2 (Trait Dimension Type: HR, PR) × 2 (Behavior Type: morality, ability) × 2 (Valence: positive, negative) × 2 (Replication: original, replication) × 2 (Sex: female or male actor) × 2 (Gender: female or male participant) × 2 (Order: attribution portion first, affect portion first) mixed design. All factors were within participants except the order and participant gender. Participants were presented with 32 different scenarios in which an actor engaged in a concrete behavior after which they made attributions and rated their affect in response to the behavior. Reaction times were measured during attribution and affect ratings. In general, the findings from the experiment supported the new predictions. Affect was related to attributions for both morality and ability related behaviors. Morality related behaviors received more extreme attribution and affect ratings than ability related behaviors. Female actors received stronger attribution and affect ratings for diagnostic morality behaviors compared to male actors. Male and female actors received similar attribution and affect ratings for diagnostic ability behaviors. Diagnostic behaviors were associated with lower reaction times than non-diagnostic behaviors. These findings demonstrate the utility of evolutionary theory in creating new hypotheses and empirical findings in the domain of attribution. PMID:29312092

Abstract The study objective was to investigate long-term effects of disease management programs (DMPs) on (1) health behaviors (smoking, physical exercise); (2) self-management abilities (self-efficacy, investment behavior, initiative taking); and (3) physical and mental quality of life among chronically ill patients. The study also examined whether (changes in) health behaviors and self-management abilities predicted quality of life. Questionnaires were sent to all 5076 patients participating in 18 Dutch DMPs in 2010 (T0; 2676 [53%] respondents). Two years later (T1), questionnaires were sent to 4350 patients still participating in DMPs (1722 [40%] respondents). Structured interviews were held with the 18 DMP project leaders. DMP implementation improved patients' health behavior and physical quality of life, but mental quality of life and self-management abilities declined over time. Changes in patients' investment behavior predicted physical quality of life at T1 (P<.001); physical activity, investment behavior (both P<.05), and self-efficacy (P<.01) at T0, and changes in self-efficacy and investment behavior (both P<.001) predicted patients' mental quality of life at T1. The long-term benefits of these DMPs include successful improvement of chronically ill patients' health behaviors and physical quality of life. However, these programs were not able to improve or maintain broader self-management abilities or mental quality of life, highlighting the need to focus on these abilities and overall quality of life. As coproducers of care, patients should be stimulated and enabled to manage their health and quality of life. (Population Health Management 2015;18:246–255) PMID:25607246

Montessori-based activities are becoming a popular approach for the care of older adults living with dementia. The aim of this study was to systematically assess the quality of the research examining the benefits of Montessori-based activities for persons with dementia. Six peer-reviewed databases were systematically searched for all relevant articles published until April 2015. Included articles were peer-reviewed studies published in English that employed Montessori-based activities with persons with dementia. Methodological quality was assessed by 2 independent raters using the Physiotherapy Evidence Database Scale or the Downs and Black evaluation tool. Levels of evidence were assigned to the study design using a modified Sackett scale. One hundred fifty articles were identified, and 14 were selected for inclusion. Level-2 evidence examining the impact of Montessori-based activities on eating behaviors suggested that difficulties with eating could be reduced with Montessori training. There was limited level-4 evidence for the benefits of Montessori-based activities on cognition, wherein benefits appeared to be specific to lower-level cognitive abilities including memory and attention. Finally, there is level-1 (n = 1), level-2 (n = 3), and level-4 (n = 6) evidence for the benefits of Montessori-based activities on engagement and affect, whereby constructive engagement and positive affect were heightened. Overall, there is a strong level of evidence for the benefits of Montessori-based activities on eating behaviors and weak evidence for the benefits on cognition. Evidence for the benefits of Montessori-based activities on engagement and affect are mixed. Future research is needed to examine the long-term benefits of Montessori-based activities.

Stigma as ego depletion: how being the target of prejudice affects self-control.

PubMed

Inzlicht, Michael; McKay, Linda; Aronson, Joshua

2006-03-01

This research examined whether stigma diminishes people's ability to control their behaviors. Because coping with stigma requires self-regulation, and self-regulation is a limited-capacity resource, we predicted that individuals belonging to stigmatized groups are less able to regulate their own behavior when they become conscious of their stigmatizing status or enter threatening environments. Study 1 uncovered a correlation between stigma sensitivity and self-regulation; the more Black college students were sensitive to prejudice, the less self-control they reported having. By experimentally activating stigma, Studies 2 and 3 provided causal evidence for stigma's ego-depleting qualities: When their stigma was activated, stigmatized participants (Black students and females) showed impaired self-control in two very different domains (attentional and physical self-regulation). These results suggest that (a) stigma is ego depleting and (b) coping with it can weaken the ability to control and regulate one's behaviors in domains unrelated to the stigma.

Determinants of consumer behavior related to organic foods.

PubMed

Shepherd, Richard; Magnusson, Maria; Sjödén, Per-Olow

2005-06-01

There have been many studies of what influences consumers in their decisions to purchase or consume organic foods, mainly concerned with fresh organic foods. These show a discrepancy between attitudes and behavior with people being positive about organic foods but often not purchasing them. This discrepancy seems to be explained by the fact that consumers do not consider "organically produced" to be an important purchase criterion, that organic foods are not perceived to surpass conventional foods regarding taste and shelf life (two qualities rated to be of great importance), and because of the perceived premium prices of organic foods. In two Swedish studies, health benefits were demonstrated to be more strongly related to attitudes and behavior toward organic foods than were perceived environmental benefits. A new European Union (EU) project will investigate the influences on both fresh and processed organic foods and investigate the role of moral, ethical, and affective influences on choice across eight EU countries.

Is there a conflicted surrogate syndrome affecting quality of care in nursing homes?

PubMed

Kidder, Samuel W; Smith, David A

2006-03-01

Is there a point at which family complaints about care cease to be constructive and become excessive and counterproductive? Do excessive complaint behaviors represent a "conflicted surrogate syndrome" that is indicative of psychopathology in the family member or family system? Can this psychopathology result in avoidance behavior by the nursing staff sufficient to result in poor care? While many family/resident complaints are valid and should be viewed as constructive there are occasions when excessive complaints by the family of a nursing facility resident are a result of psychiatric illness or psychological problems in the family member(s) or are evidence of an abnormality in the family system. This series of brief case reports is offered to create discussion of what might be termed a "conflicted surrogate syndrome" that may result in avoidance behavior by staff and consequent poor care.

Young, Brent Kevin; Brennan, Jayden Nicole; Wang, Ping; Tian, Ning

Behavioral tests have been extensively used to measure the visual function of mice. To determine how precisely mice perceive certain visual cues, it is necessary to have a quantifiable measurement of their behavioral responses. Recently, virtual reality tests have been utilized for a variety of purposes, from analyzing hippocampal cell functionality to identifying visual acuity. Despite the widespread use of these tests, the training requirement for the recognition of a variety of different visual targets, and the performance of the behavioral tests has not been thoroughly characterized. We have developed a virtual reality behavior testing approach that can essay a variety of different aspects of visual perception, including color/luminance and motion detection. When tested for the ability to detect a color/luminance target or a moving target, mice were able to discern the designated target after 9 days of continuous training. However, the quality of their performance is significantly affected by the complexity of the visual target, and their ability to navigate on a spherical treadmill. Importantly, mice retained memory of their visual recognition for at least three weeks after the end of their behavioral training.

Feeling Validated Versus Being Correct:A Meta-Analysis of Selective Exposure to Information

A meta-analysis assessed whether exposure to information is guided by defense or accuracy motives. The studies examined information preferences in relation to attitudes, beliefs, and behaviors in situations that provided choices between congenial information, which supported participants' pre-existing attitudes, beliefs, or behaviors, and uncongenial information, which challenged these tendencies. Analyses indicated a moderate preference for congenial over uncongenial information (d. = 0.36). As predicted, this congeniality bias was moderated by variables that affect the strength of participants' defense motivation and accuracy motivation. In support of the importance of defense motivation, the congeniality bias was weaker when participants' attitudes, beliefs, or behaviors were supported prior to information selection, when participants' attitudes, beliefs, or behaviors were not relevant to their values or not held with conviction, when the available information was low in quality, when participants' closed-mindedness was low, and when their confidence in the attitude, belief, or behavior was high. In support of the importance of accuracy motivation, an uncongeniality bias emerged when uncongenial information was relevant to accomplishing a current goal. PMID:19586162

Rapid adaptation to changes, while maintaining a certain level of behavioral inhibition is an important feature in every day functioning. How environmental context and challenges in life can impact on the development of this quality is still unknown. In the present study, we examined the effect of a complex rearing environment during adolescence on attention and behavioral inhibition in adult male rats. We also tested whether these effects were affected by an adverse early life challenge, maternal deprivation (MD). We found that animals that were raised in large, two floor MarlauTM cages, together with 10 conspecifics, showed improved attention, but impaired behavioral inhibition in the 5-choice serial reaction time task. The early life challenge of 24 h MD on postnatal day 3 led to a decline in bodyweight during adolescence, but did not by itself influence responses in the 5-choice task in adulthood, nor did it moderate the effects of complex housing. Our data suggest that a complex rearing environment leads to a faster adaptation to changes in the environment, but at the cost of lower behavioral inhibition. PMID:26733839

No Effect of Ambient Odor on the Affective Appraisal of a Desktop Virtual Environment with Signs of Disorder

2013-01-01

Background Desktop virtual environments (VEs) are increasingly deployed to study the effects of environmental qualities and interventions on human behavior and safety related concerns in built environments. For these applications it is essential that users appraise the affective qualities of the VE similar to those of its real world counterpart. Previous studies have shown that factors like simulated lighting, sound and dynamic elements all contribute to the affective appraisal of a desktop VE. Since ambient odor is known to affect the affective appraisal of real environments, and has been shown to increase the sense of presence in immersive VEs, it may also be an effective tool to tune the affective appraisal of desktop VEs. This study investigated if exposure to ambient odor can modulate the affective appraisal of a desktop VE with signs of public disorder. Method Participants explored a desktop VE representing a suburban neighborhood with signs of public disorder (neglect, vandalism and crime), while being exposed to either room air or subliminal levels of unpleasant (tar) or pleasant (cut grass) ambient odor. Whenever they encountered signs of disorder they reported their safety related concerns and associated affective feelings. Results Signs of crime in the desktop VE were associated with negative affective feelings and concerns for personal safety and personal property. However, there was no significant difference between reported safety related concerns and affective connotations in the control (no-odor) and in each of the two ambient odor conditions. Conclusion Ambient odor did not affect safety related concerns and affective connotations associated with signs of disorder in the desktop VE. Thus, semantic congruency between ambient odor and a desktop VE may not be sufficient to influence its affective appraisal, and a more realistic simulation in which simulated objects appear to emit scents may be required to achieve this goal.

Factors Associated With Short- and Long-term Liver Graft Survival in the United Kingdom: Development of a UK Donor Liver Index.

PubMed

Collett, David; Friend, Peter J; Watson, Christopher J E

2017-04-01

A measure of donor liver quality, the donor liver index, was developed and validated for the UK population of transplant recipients. Unlike previously proposed measures, this index is only based on variables that are available at the point of retrieval, and so does not include cold ischemic time. Indices of liver quality were based on data from the UK Transplant Registry on all 7929 liver transplants between January 2000 and December 2014. The donor liver index (DLI) was based on factors shown to affect graft survival, which included donor age, sex, height, type (donor after brain death or circulatory death), bilirubin, smoking history, and whether the liver was split. A separate index (DLI1) looking at 1-year survival showed donor cardiac disease, black ethnicity, and steatosis to be additional risk factors. A strong association was found between DLI and whether or not a surgeon accepts an offered liver for transplant, with a marked fall in acceptance rates for livers with an index greater than 1.31. Since 2000, there has been a notable reduction in the quality of livers transplanted, coupled with variation between the 7 UK liver transplant centers in risk appetite. The DLI is an index of liver quality which enables analysis of the changing trends in liver quality and center behavior. DLI1 enables identification of factors affecting shorter-term survival, and perhaps identifies a cohort of livers that may benefit from novel preservation technologies.

Key sleep neurologic disorders

PubMed Central

St. Louis, Erik K.

2014-01-01

Summary Sleep disorders are frequent comorbidities in neurologic patients. This review focuses on clinical aspects and prognosis of 3 neurologic sleep disorders: narcolepsy, restless legs syndrome/Willis-Ekbom disease (RLS/WED), and REM sleep behavior disorder (RBD). Narcolepsy causes pervasive, enduring excessive daytime sleepiness, adversely affecting patients' daily functioning. RLS/WED is characterized by an uncomfortable urge to move the legs before sleep, often evolving toward augmentation and resulting in daylong bothersome symptoms. RBD causes potentially injurious dream enactment behaviors that often signify future evolution of overt synucleinopathy neurodegeneration in as many as 81% of patients. Timely recognition, referral for polysomnography, and longitudinal follow-up of narcolepsy, RLS/WED, and RBD patients are imperatives for neurologists in providing quality comprehensive patient care.

Is courtship intensity a signal of male parental care in Red-winged Blackbirds (Agelaius phoeniceus)?

Yasukawa, Ken; Knight, Richard L.; Skagen, Susan Knight

1987-01-01

We studied Red-winged Blackbird (Agelaius phoeniceus) behavior in marsh and prairie habitats to determine whether courting males provide cues of their nest defense, whether females prefer males that defend nests vigorously, and whether male nest defense affects nest success. We found no evidence that courtship behavior provides cues of male nest defense, or that females prefer males that court intensely. We found evidence that females nesting in marshes prefer males that defend nests intensely, but no evidence that intensely defending males in the prairie habitat achieve high nest success. We found differences, however, between marsh and prairie habitats that suggest a coarse-grained relationship between male parental quality and female choice of mate in this species.

Parents Perceive Improvements in Socio-emotional Functioning in Adolescents with ASD Following Social Skills Treatment.

2017-01-01

The current study examined the effectiveness of a social skills treatment (PEERS) for improving socio-emotional competencies in a sample of high-functioning adolescents with ASD. Neuropsychological and self- and parent-report measures assessing social, emotional, and behavioral functioning were administered before and after treatment. Following social skills treatment, adolescents with ASD exhibited decreased aggression, anxiety, and withdrawal, as well as improvements in emotional responsiveness, adaptability, leadership, and participation in activities of daily living, though no change was found in affect recognition abilities. These findings suggest that PEERS social skills treatment improves particular aspects of emotional, behavioral, and social functioning that may be necessary for developing and maintaining quality peer relationships and remediating social isolation in adolescents with ASD.

Using a biopsychosocial perspective in the treatment of fibromyalgia patients.

PubMed

Turk, Dennis C; Adams, Leah M

2016-05-01

Fibromyalgia (FM) is a complex illness that manifests in different ways across individuals. Given that there are currently no known cures for FM, like treatment for other chronic diseases, interventions focus on learning strategies to alleviate symptom severity, to cope with and manage residual symptoms of the illness and to maximize health-related quality of life despite symptoms. In this article, we highlight the need for providers to adopt a biopsychosocial perspective for understanding and addressing patients with FM, noting that biological, psychosocial and behavioral factors function interdependently to affect a person's experience and adaptation. A cognitive-behavioral approach, which incorporates a biopsychosocial perspective, is detailed, along with specific treatment considerations for helping patients with FM manage their symptoms.

[Effects of a non-face-to-face behavioral intervention on poor sleepers and factors affecting improvement of sleep].

2010-03-01

The purposes of this study were 1) to re-examine effects obtained from previous research of a non-face-to-face behavioral intervention in poorer sleepers and 2) to examine the factors impacting on improvement of sleep. The subjects were 178 poor sleepers who participated in an intervention for sleep improvement. The educational procedures comprised a minimal behavioral self-help package for one month that featured self- learning and self- monitoring of practical target habits for change. It was non face-to-face program conducted by only one member of staff. Subjects were asked to answer a questionnaire before and after the intervention. To reexamine the effects of this program found in our previous research, 9 sleep indices, sleep quality, and sleep-related behaviors were compared between before and after intervention. The sleep indices were total sleep time, sleep onset latency, sleep efficiency etc. Subjects were divided into an improvement group (n = 63) and a non-improvement group (n = 115) using a cutoff value for average change in sleep onset latency and sleep efficiency. After comparison of sleep and behavior between the two groups, logistic regression analysis was conducted to select parameters affecting improvement with this program. Total sleep time was significantly increased from 5.7 h to 6.1 h, sleep onset time decreased 18 minutes, and sleep efficiency improved 5.6 points. With 8 of 9 sleep-related behaviors, the proportion of subjects having an undesirable habit significantly decreased. The mean total number of desirable habit' changes was 2.63 in the improvement group and significantly higher than the 2.06 in the non-improvement group. Logistic regression analysis demonstrated that large sleep onset latency at baseline and beginning of regular exercise significantly affected the improvement of sleep in the subjects, after adjusting for all other parameters. The effects revealed by our previous research were reconfirmed. It is suggested that this program is more useful for persons having severe sleep onset difficulties, and regular exercise is particularly important in improvement of sleep. It is possible that even simple behavioral intervention is feasible with many subjects to improve sleep and related habits in poor sleepers.

Sleep, health behaviors, and behavioral interventions: Reducing the risk of cardiovascular disease in adults

PubMed Central

Kaar, Jill L; Luberto, Christina M; Campbell, Kirsti A; Huffman, Jeff C

2017-01-01

Numerous health behaviors, including physical activity, diet, smoking, and sleep, play a major role in preventing the development and progression of cardiovascular disease (CVD). Among these behaviors, sleep may play a pivotal role, yet it has been studied somewhat less than other behaviors and there have been few well-designed sleep intervention studies targeting CVD. Furthermore, despite the fact that these behaviors are often interrelated, interventions tend to focus on changing one health behavior rather than concurrently intervening on multiple behaviors. Psychological constructs from depression to positive affect may also have a major effect on these health behaviors and ultimately on CVD. In this review, we summarize the existing literature on the impact of sleep and other cardiac health behaviors on CVD onset and prognosis. We also describe interventions that may promote these behaviors, from established interventions such as motivational interviewing and cognitive behavioral therapy, to more novel approaches focused on mindfulness and other positive psychological constructs. Finally, we outline population-health-level care management approaches for patients with psychiatric conditions (e.g., depression) that may impact cardiac health, and discuss their potential utility in improving mental health, promoting health behaviors, and reducing CVD-related risk. Much work is still needed to better understand how sleep and other health behaviors may uniquely contribute to CVD risk, and additional high-quality studies of interventions designed to modify cardiac health behaviors are required to improve cardiovascular health in individuals and the population at large.

Potential Adverse Effects of Violent Video Gaming: Interpersonal- Affective Traits Are Rather Impaired Than Disinhibition in Young Adults.

Kimmig, Ann-Christin S; Andringa, Gerda; Derntl, Birgit

2018-01-01

The increasing trend of mass shootings, which were associated with excessive use of violent video games, fueled the debate of possible effects violent video games may have on adolescents and young adults. The aim of this study was to investigate the possible link between violent video gaming effects and the disposition of adverse behavior traits such as interpersonal-affective deficits and disinhibition. Data of 167 young adults, collected by an online questionnaire battery, were analyzed for lifetime video game exposure differences (i.e., non-gamers, non-violent video gamers, stopped violent video game users, and ongoing violent video game users) as well as for recent exposure effects on adverse behavior traits (Levenson's Psychopathy Scale), while controlling for other potentially confounding lifestyle factors. While interpersonal-affective deficits were significantly higher in participants with ongoing violent video game exposure compared to non-gamers and non-violent video gamers, disinhibition was significantly higher in both - stopped and ongoing - violent video game exposure groups compared to non-gamers. Recent violent video game exposure was a stronger predictor for interpersonal-affective deficits, but was also significant for disinhibition. Considering that we observed small to medium effects in a sample of young adults with little to moderate use of violent video games highlights the importance of further investigating the potential adverse effects of violent video games on quality of social relationships.

Optimization and Characterization of the Friction Stir Welded Sheets of AA 5754-H111: Monitoring of the Quality of Joints with Thermographic Techniques.

2017-10-11

Friction Stir Welding (FSW) is a solid-state welding process, based on frictional and stirring phenomena, that offers many advantages with respect to the traditional welding methods. However, several parameters can affect the quality of the produced joints. In this work, an experimental approach has been used for studying and optimizing the FSW process, applied on 5754-H111 aluminum plates. In particular, the thermal behavior of the material during the process has been investigated and two thermal indexes, the maximum temperature and the heating rate of the material, correlated to the frictional power input, were investigated for different process parameters (the travel and rotation tool speeds) configurations. Moreover, other techniques (micrographs, macrographs and destructive tensile tests) were carried out for supporting in a quantitative way the analysis of the quality of welded joints. The potential of thermographic technique has been demonstrated both for monitoring the FSW process and for predicting the quality of joints in terms of tensile strength.

High quality fuel gas from biomass pyrolysis with calcium oxide.

The removal of CO2 and tar in fuel gas produced by biomass thermal conversion has aroused more attention due to their adverse effects on the subsequent fuel gas application. High quality fuel gas production from sawdust pyrolysis with CaO was studied in this paper. The results of pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) experiments indicate that the mass ratio of CaO to sawdust (Ca/S) remarkably affects the behavior of sawdust pyrolysis. On the basis of Py-GC/MS results, one system of a moving bed pyrolyzer coupled with a fluid bed combustor has been developed to produce high quality fuel gas. The lower heating value (LHV) of the fuel gas was above 16MJ/Nm(3) and the content of tar was under 50mg/Nm(3), which is suitable for gas turbine application to generate electricity and heat. Therefore, this technology may be a promising route to achieve high quality fuel gas for biomass utilization. Copyright © 2014 Elsevier Ltd. All rights reserved.

Psychiatric symptoms and same-sex sexual attraction and behavior in light of childhood gender atypical behavior and parental relationships.

This study explores the relation between the level of current symptoms of depression and anxiety and recalled childhood gender atypical behavior (GAB), and quality of relationships with parents among men and women who reported same-sex sexual attraction or engaged in same-sex sexual behavior and men and women who did not. Matched pairs, 79 men (n = 158) and 148 women (n = 296), with equal levels of GAB were created of Finnish participants with either same-sex sexual attraction or behavior and participants without. The measures used were retrospective questionnaires. Ratings of maternal and paternal over-control and coldness differed as a function of same-sex sexual attraction or behavior. Childhood GAB was correlated with negative ratings of parental relationships. Both same-sex sexual attraction or behavior and a history of childhood GAB affected the reported levels of current depression and anxiety. Only gender typical participants with no same-sex sexual attraction or behavior reported significantly lower levels of symptoms. The findings suggest that childhood GAB is related to later distress both among hetero- and homosexual individuals. The elevated level of psychological distress among homosexual individuals, reported in several studies, might--to some extent--be caused by their generally higher levels of childhood GAB as opposed to a homosexual orientation per se.

Temporal associations between affective instability and dysregulated eating behavior in bulimia nervosa.

2017-09-01

Prior research suggests that the construct of emotional instability may be salient to bulimia nervosa (BN), but no study to date has used ecological momentary assessment (EMA) to examine its temporal association with binge eating and purging. In the current study, 133 women with DSM-IV BN used portable digital devices to provide multiple daily negative affect (NA) and positive affect (PA) ratings and record eating disorder behaviors over 2 weeks. Two state-of-the art indices quantified affective instability: probability of acute change (PAC), which represents the likelihood of extreme affective increases, and mean squared successive difference (MSSD), which represents average change over successive recordings. For extreme affective change, results revealed that on bulimic behavior days, extreme NA increases were less likely after bulimic behaviors than before them, and extreme increases in PA were more likely after bulimic behaviors than during the same time period on non-bulimic behavior days. However, average NA instability (i.e., MSSD) was (a) greater on bulimic behavior days than non-bulimic behavior days, (b) greater after bulimic behaviors than during the same time period on non-bulimic behavior days, and (c) greater after bulimic behaviors than before them. Results lend support to the notion that bulimic behaviors are negatively reinforcing (i.e., via post-behavior acute affective changes), but also indicate that these behaviors may exacerbate overall affective dysregulation. These findings may improve understanding of BN maintenance and inform the development of novel interventions or refinement of existing treatments. Copyright © 2017 Elsevier Ltd. All rights reserved.

A review and meta-analysis of affective judgments and physical activity in adult populations.

Rhodes, Ryan E; Fiala, Bonnie; Conner, Mark

2009-12-01

Popular theories of health behavior have often been criticized for neglecting an affective component to behavioral engagement. This study reviewed affective judgment (AJ) constructs employed in physical activity research to assess the relationship with behavior. Studies were eligible if they included: (a) a measure of physical activity; (b) a distinct measure of AJ (e.g., affective attitude, enjoyment, intrinsic motivation); and (c) involved participants with a mean age of 18 years or older. Literature searches were concluded in September, 2009 among five key search engines. This search yielded a total of 10,631 potentially relevant records; of these, 102 passed the eligibility criteria. Random effects meta-analysis procedures with correction for sampling and measurement bias were employed in the analysis. Articles were published between 1989 and 2009, with sample sizes ranging from 15 to 6,739. Of the studies included, 82 were correlational and 20 were experimental, yielding 114 independent samples. The majority of the correlational samples reported a significant positive correlation between AJ and physical activity (83 out of 85), with a summary r of 0.42 (95% CI 0.37 to 0.46) that was invariant across the measures employed, study quality, population sampled and cultural variables. Experimental studies demonstrated that persuasive, information-based, and self-regulatory interventions failed to change AJ; by contrast, environmental and experiential interventions showed promise in their capability to influence AJ. The results point to a medium-effect size relationship between AJ and physical activity. Interventions that change AJ are scarce despite their potential for changing physical activity. Future experimental work designed to evaluate the causal impact ofAJ on physical activity is required.

The ventral visual pathway: an expanded neural framework for the processing of object quality.

2013-01-01

Since the original characterization of the ventral visual pathway, our knowledge of its neuroanatomy, functional properties, and extrinsic targets has grown considerably. Here we synthesize this recent evidence and propose that the ventral pathway is best understood as a recurrent occipitotemporal network containing neural representations of object quality both utilized and constrained by at least six distinct cortical and subcortical systems. Each system serves its own specialized behavioral, cognitive, or affective function, collectively providing the raison d'être for the ventral visual pathway. This expanded framework contrasts with the depiction of the ventral visual pathway as a largely serial staged hierarchy culminating in singular object representations and more parsimoniously incorporates attentional, contextual, and feedback effects.

The Balanced Budget Act of 1997 dramatically changed the way that Medicare pays skilled nursing facilities, providing a natural experiment in nursing home behavior. Medicare payment policy (directed at short-stay residents) may have affected outcomes for long-stay, chronic-care residents if services for these residents were subsidized through cost-shifting prior to implementation of Medicare prospective payment for nursing homes. We link changes in both the form and level of Medicare payment at the facility level with changes in resident-level quality, as represented by pressure sores and urinary tract infections in Minimum Data Set (MDS) assessments. Results show that long-stay residents experienced increased adverse outcomes with the elimination of Medicare cost reimbursement.

Behavioral and psychological symptoms in dementia (BPSD) are important predictors of institutionalization as well as caregiver burden and depression. Previous reviews have tended to group BPSD as one category with little focus on the role of the individual symptoms. This review investigates the role of the individual symptoms of BPSD in relation to the impact on different measures of family caregiver well-being. Systematic review and meta-analysis of papers published in English between 1980 and December 2015 reporting which BPSD affect caregiver well-being. Paper quality was appraised using the Downs and Black Checklist (1998). Forty medium and high quality quantitative papers met the inclusion criteria, 16 were suitable to be included in a meta-analysis of mean distress scores. Depressive behaviors were the most distressing for caregivers followed by agitation/aggression and apathy. Euphoria was the least distressing. Correlation coefficients between mean total behavior scores and mean distress scores were pooled for four studies. Irritability, aberrant motor behavior and delusions were the most strongly correlated to distress, disinhibition was the least correlated. The evidence is not conclusive as to whether some BPSD impact caregiver well-being more than others. Studies which validly examined BPSD individually were limited, and the included studies used numerous measures of BPSD and numerous measures of caregiver well-being. Future research may benefit from a consistent measure of BPSD, examining BPSD individually, and by examining the causal mechanisms by which BPSD impact well-being by including caregiver variables so that interventions can be designed to target BPSD more effectively.

Behavioral symptoms such as repetitive statements and questions, wandering, and sleep disturbances are a core clinical feature of Alzheimer disease and related dementias, affecting patients and their families. These behaviors have devastating effects. If untreated, they can contribute to more rapid disease progression, earlier nursing home placement, worse quality of life, accelerated functional decline, greater caregiver distress, and higher health care utilization and costs. Patients with dementia are typically not screened for behavioral symptoms in primary care and even when clinically reported, tend to receive ineffective, inappropriate, and fragmented care. Yet, clinicians are often called upon to address behaviors that place the patient or others at risk or which families encounter as problematic. It is important to include on-going systematic screening for behavioral symptoms to facilitate prevention and early treatment as part of standard comprehensive dementia care. When identified, behaviors should be characterized and underlying causes sought in order to derive a treatment plan. Because available pharmacologic treatments used to treat behaviors have modest efficacy at best, are associated with notable risks, and do not address behaviors most distressing for families, nonpharmacologic options are recommended as first-line treatments or if necessary, in parallel with pharmacologic or other treatment options. Nonpharmacologic treatments may include a general approach (caregiver education and training in problem solving, communication and task simplification skills, patient exercise, and/or activity programs), or a targeted approach in which precipitating conditions of a specific behavior are identified and modified (eg, implementing nighttime routines to address sleep disturbances). Using the case of Mr A, we characterize common behavioral symptoms of dementia and describe an assessment strategy for selecting evidence-based nonpharmacologic treatments. We highlight the clinician's important role in facilitating collaboration with specialists and other health care professionals to implement nonpharmacological treatment plans. Substantial evidence shows that nonpharmacologic approaches can yield high levels of patient and caregiver satisfaction, quality of life improvements, and reductions in behavioral symptoms. Although access to nonpharmacologic approaches is currently limited, they should be part of standard dementia care. PMID:23168825

Future health-related behavioral intention formation: the role of affect and cognition.

This study investigated the differential contribution of affect and cognition to behavioral intention formation during pursuit of future health-related goals. Cognitive evaluations, affective evaluations and behavioral intentions were measured for each of 32 health-related behaviors. The timeframes of the cognitive/affective measures and the behavioral intention measure were varied between current and future timeframes creating four different conditions. Within-participants correlations between affect and intentions and cognition and intentions were calculated to determine the contribution of each factor to behavioral intention formation in the different timeframes. Results did not support the hypothesis that a shift from a reliance on affect to a reliance on cognition would occur as temporal distance increased. Within-participants analyses revealed a decrease in the contribution of cognition to behavioral intention formation when forming attitudes in the future condition.

Etiological and maintenance models for disordered eating highlight the salience of negative affect and interpersonal dysfunction. This study employed a 14-day experience sampling procedure to assess the impact of negative affect and interpersonal perceptions on binge eating behavior. Young adult women (N = 40) with recurrent binge eating and significant clinical impairment recorded their mood, interpersonal behavior, and eating behaviors at six stratified semirandom intervals daily through the use of personal digital assistants. Although momentary negative affect was associated with binge eating behavior, average levels of negative affect over the experience sampling period were not, and interpersonal problems moderated the relationship between negative affect and binge eating. Interpersonal problems also intensified the association between momentary interpersonal perceptions and binge eating behavior. Lagged analyses indicated that previous levels of negative affect and interpersonal style also influence binge eating. The study findings suggest there may be important differences in how dispositional versus momentary experiences of negative affect are associated with binge eating. Results also highlight the importance of interpersonal problems for understanding relationships among negative affect, interpersonal perception, and binge eating behavior. These results offer several possibilities for attending to affective and interpersonal functioning in clinical practice. © 2015 Wiley Periodicals, Inc.

2016-01-01

Reproductive division of labor is one of the defining traits of honey bees (Apis mellifera), with non-reproductive tasks being performed by workers while a single queen normally monopolizes reproduction. The decentralized organization of a honey bee colony is maintained in large part by a bouquet of queen-produced pheromones, the distribution of which is facilitated by contact among workers throughout the hive. Previous studies have shown that the developmental fate of honey bee queens is highly plastic, with queens raised from younger worker larvae exhibiting higher measures of reproductive potential compared to queens raised from older worker larvae. We investigated differences in the chemical composition of the mandibular glands and attractiveness to workers of "high-quality" queens (i.e., raised from first instar worker larvae; more queen-like) and "low-quality" queens (i.e., raised from third instar worker larvae; more worker-like). We characterized the chemical profiles of the mandibular glands of high-quality queens and low-quality queens using GC-MS and used the worker retinue response as a measure of the attractiveness to workers of high-quality queens vs. low-quality queens. We found that queen quality affected the chemical profiles of mandibular gland contents differently across years, showing significant differences in the production of the queen mandibular pheromone ("QMP") components HVA and 9-HDA in 2010, but no significant differences of any glandular compound in 2012. We also found that workers were significantly more attracted to high-quality queens than to low-quality queens in 2012, possibly because of increased attractiveness of their mandibular gland chemical profiles. Our results indicate that the age at which honey bee larvae enter the "queen-specific" developmental pathway influences the chemical composition of queen mandibular glands and worker behavior. However, these changes are not consistent across years, suggesting that other external factors may play important roles in modulating queen quality.

Drive-level dependence of doubly rotated langasite resonators with different configurations.

The miniaturization of crystal resonators and filters toward the micro electromechanical systems (MEMS) and nano-structured scales demands improvement of nonlinear piezoelectricity theory and a better understanding of the nonlinear behavior of new crystal materials. The nonlinearities affect the quality factor and acoustic behavior of MEMS and nano-structured resonators and filters. Among these nonlinear effects, drive-level dependence (DLD), which describes the instability of the resonator frequency resulting from voltage level and/or power density, is a potentially significant problem for miniaturized resonators. Langasite, a promising new piezoelectric material, is of current interest for a variety of applications because of its good temperature behavior, good piezoelectric coupling, low acoustic loss, and high Q-factor. It has been recently used to make high-temperature MEMS. In this paper, we report experimental measurements of the DLD of langasite resonators with different resonator configurations (plano-plano, single bevel, and double bevel). The results show that the resonator configuration affects the DLD of the langasite resonator. The DLD measurement results for langasite are compared with literature values for quartz, langaniste, and langatate, and with additional new measurements for a GaPO4 resonator of type R-30 (-11.1° rotated Y-cut). Uncertainty analysis for the measured drive-level sensitivity is performed as well.

Despite the increasing attention to social appraisals in suicide risk, the interpersonal correlates of suicidal thoughts and behavior in schizophrenia are not well understood. Ecological momentary assessment could reveal whether dysfunctional social appraisals and behavior are evident in people with schizophrenia with suicidal ideation. A total of 93 outpatients with diagnoses of schizophrenia with (n = 18, 19%) and without (N = 75; 81%) suicidal ideation participated in one week of intensive daily monitoring via mobile devices, generating real-time reports on the quantity of social interactions and appraisals about them, as well as information concerning concurrent affect and symptoms. The presence of suicidal ideation was not associated with the quantity of social interactions or time spent alone, but it was associated with the anticipation of being alone as well as greater negative and lower positive affect when alone. Despite this aversive experience of being alone, people with suicidal ideation reported negative appraisals about the value of recent and potential social interactions. These findings suggest that suicidal ideation in schizophrenia may not be associated with the quantity of social interactions, but with negative expectations about the quality of social interactions coupled with an aversive experience of being alone. Cognitive therapy interventions that address negative expectations and pleasure about social interactions, especially when alone, may reduce suicidal ideation. PMID:26948502

Adolescents' aggressive and prosocial behaviors: links with social information processing, negative emotionality, moral affect, and moral cognition.

2014-01-01

The goal of this study was to examine whether moral affect, moral cognition, negative emotionality, and attribution biases independently predicted adolescents' prosocial and aggressive behavior in adolescence. A total of 148 adolescents completed self-report measures of prosocial and aggressive behavior, moral affect, moral cognition, negative emotionality, and attribution biases. Although in general all 3 factors (emotional, moral, and social cognitive) were correlated with adolescent social behavior, the most consistent independent predictors of adolescent social behavior were moral affect and cognition. These findings have important implications for intervention and suggest that programs that promote adolescent perspective taking, moral reasoning, and moral affect are needed to reduce aggressive behavior and promote prosocial behavior.

Objective In clinical practice, behavioral approaches to obesity treatment focus heavily on diet and exercise recommendations. However, these approaches may not be effective for patients with disordered eating behaviors. Little is known about the prevalence of disordered eating behaviors in primary care patients with obesity or whether they affect difficulty making dietary changes. Methods We conducted a telephone interview of 337 primary care patients aged 18–65 years with BMI≥35kg/m2 in Greater-Boston, 2009–2011 (58% response rate, 69% women). We administered the Three-Factor Eating Questionnaire R-18 (Scores 0–100) and the Impact of Weight on Quality of Life-Lite (IWQOL-lite) (Scores 0–100). We measured difficulty making dietary changes using four questions regarding perceived difficulty changing diet (Scores 0–10). Results 50% of patients reported high emotional eating (score>50) and 28% reported high uncontrolled eating (score>50). Women were more likely to report emotional [OR=4.14 (2.90, 5.92)] and uncontrolled eating [OR=2.11 (1.44, 3.08)] than men. African Americans were less likely than Caucasians to report emotional [OR=0.29 (95% CI: 0.19, 0.44)] and uncontrolled eating [OR=0.11 (0.07, 0.19)]. For every 10-point reduction in QOL score (IWQOL-lite), emotional and uncontrolled eating scores rose significantly by 7.82 and 5.48, respectively. Furthermore, participants who reported emotional and uncontrolled eating reported greater difficulty making dietary changes. Conclusions Disordered eating behaviors are prevalent among obese primary care patients and disproportionately affect women, Caucasians, and patients with poor QOL. These eating behaviors may impair patients' ability to make clinically recommended dietary changes. Clinicians should consider screening for disordered eating behaviors and tailoring obesity treatment accordingly. PMID:25572624

It is widely accepted that lifestyle plays a crucial role on the quality of life in individuals, particularly in western societies where poor diet is correlated to alterations in behavior and the increased possibility of developing type-2 diabetes. While exercising is known to produce improvements to overall health, there is conflicting evidence on how much of an effect exercise has staving off the development of type-2 diabetes or counteracting the effects of diet on anxiety. Thus, this study investigated the effects of voluntary wheel-running access on the progression of diabetes-like symptoms and open field and light-dark box behaviors in C57BL/6J mice fed a high-fat diet. C57BL/6J mice were placed into either running-wheel cages or cages without a running-wheel, given either regular chow or a high-fat diet, and their body mass, food consumption, glucose tolerance, insulin and c-peptide levels were measured. Mice were also exposed to the open field and light-dark box tests for anxiety-like behaviors. Access to a running-wheel partially attenuated the obesity and hyperinsulinemia associated with high-fat diet consumption in these mice, but did not affect glucose tolerance or c-peptide levels. Wheel-running strongly increased anxiety-like and decreased explorative-like behaviors in the open field and light-dark box, while high-fat diet consumption produced smaller increases in anxiety. These results suggest that voluntary wheel-running can assuage some, but not all, of the physiological problems associated with high-fat diet consumption, and can modify anxiety-like behaviors regardless of diet consumed.

Floyd, F J; Gilliom, L A; Costigan, C L

1998-10-01

The study evaluates how marriage and the parenting alliance affect parenting experiences over time. Couples (N = 79) with school-age children who have mental retardation completed self-report and observational measures of marriage, the parenting alliance, and parenting attitudes and behaviors at 2 periods, 18-24 months apart. Longitudinal structural equation modeling demonstrated significant effects of marital quality on changes over time in self-reports of perceived parenting competence for both the mothers and the fathers, and in observed negative mother-child interactions. Also, in all cases, the parenting alliance mediated the effects of marriage on parenting experiences. There was little evidence of reciprocal causation in which parenting variables predicted change in the quality of marriage and the parenting alliance. Interactions involving child age suggested that teenagers as opposed to younger children were more reactive to negative features of their parents' marital functioning and parenting alliance. Implications are discussed regarding stable but negative marital functioning and regarding possible differences in mothers' and fathers' parenting in the context of marital distress.

This study compares the effects of feeding growing rats with increasing concentrations of casein (C) and wheat gluten (G), proteins that show different biological qualities, on the morphometrical and biomechanical properties of the femoral diaphysis. Female rats were fed with one of ten diets containing different concentrations (5-30%) of C and G between the 30th and 90th days of life (Control=C-20%). Biomechanical structural properties of the right femur middiaphysis were estimated using a 3-point bending mechanical test with calculation of some indicators of bone material properties. Body weight and length were affected by treatments, values being highest in rats fed the C-20% diet. G diets affected negatively both parameters. Changes in cross-sectional geometry (mid-diaphyseal cross-sectional and cortical areas, femoral volume, and rectangular moment of inertia) were positively related to the C content of the diet, while they were severely and negatively affected by G diets. Similar behaviors were observed in the bone structural properties (fracture load, yielding load, diaphyseal stiffness and elastic energy absorption). When values of strength and stiffness were normalized for body weight, the differences disappeared. The bone material quality indicators (elastic modulus, yielding stress, elastic energy absorption/volume) did not differ significantly among all studied groups. Femoral calcium concentration in ashes was not significantly different among groups. The clear differences in strength and stiffness of bone beams induced by dietary protein concentration and quality seemed to be the result of an induced subnormal gain in bone structural properties as a consequence of a correlative subnormal gain in bone growth and mass, yet not in bone material properties.

Narcissism has significant interpersonal costs, yet little research has examined behavioral and affective patterns characteristic of narcissism in naturalistic settings. Here we studied the effect of narcissistic features on the dynamic processes of interpersonal behavior and affect in daily life. We used interpersonal theory to generate transactional models of social interaction (i.e., linkages among perceptions of others' behavior, affect, and one's own behavior) predicted to be characteristic of narcissism. Psychiatric outpatients (N = 102) completed clinical interviews and a 21-day ecological momentary assessment protocol using smartphones. After social interactions (N = 5,781), participants reported on perceptions of their interaction partner's behavior (scored along the dimensions of dominant-submissive and affiliative-quarrelsome), their own affect, and their own behavior. Multilevel structural equation modeling was used to examine dynamic links among behavior and affect across interactions, and the role of narcissism in moderating these links. Results showed that perceptions of others' dominance did not predict dominant behavior, but did predict quarrelsome behavior, and this link was potentiated by narcissism. Furthermore, the link between others' dominance and one's own quarrelsome behavior was mediated by negative affect. Moderated mediation was also found: Narcissism amplified the link between ratings of others' dominance and one's own quarrelsomeness and negative affect. Narcissism did not moderate the link between other dominance and own dominance, nor the link between other affiliation and own affiliation. These results suggest that narcissism is associated with specific interpersonal and affective processes, such that sensitivity to others' dominance triggers antagonistic behavior in daily life.

Colorectal carcinoma is one of the most common malignancies worldwide and the most prevalent cause of cancer mortality in China. The Miles operation and permanent colostomy are effective treatment. However, these affect the quality of life of patients as they alter normal defecation. Self-efficacy is used to define an individuals' assessments of their ability to perform a specific behavior successfully. It is regarded as an important belief that can predict health behaviors. The aim of this study was to explore the effect of a self-efficacy intervention on the quality of life of patients with a permanent colostomy. Forty-eight patients in treatment for permanent colostomy surgery were divided into the control and intervention groups. The control group received routine nursing; the intervention group was exposed to a 3-month self-efficacy intervention, as well as routine nursing. The two groups completed the Chinese version of a self-efficacy questionnaire at 10 days, 1 month, and 3 months after surgery. Three months after surgery, the two groups also completed a quality-of-life questionnaire. There were significant differences in the quality of life between the two groups. The self-efficacy intervention nursing method improved self-efficacy and the quality of life of patients with intestinal stoma and is worthy of clinical utilization and application.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

Intrapersonal Variability in Negative Affect as a Moderator of Accuracy and Bias in Interpersonal Perception.

Sadikaj, Gentiana; Moskowitz, D S; Zuroff, David C

2015-08-01

High intrapersonal variability has frequently been found to be related to poor personal and interpersonal outcomes. Little research has examined processes by which intrapersonal variability influences outcomes. This study explored the relation of intrapersonal variability in negative affect (negative affect flux) to accuracy and bias in the perception of a romantic partner's quarrelsome behavior. A sample of 93 cohabiting couples participated in a study using an event-contingent recording (ECR) methodology in which they reported their negative affect, quarrelsome behavior, and perception of their partner's quarrelsome behavior in interactions with each other during a 20-day period. Negative affect flux was operationalized as the within-person standard deviation of negative affect scores across couple interactions. Findings suggested that participants were both accurate in tracking changes in their partner's quarrelsome behavior and biased in assuming their partner's quarrelsome behavior mirrored their own quarrelsome behavior. Negative affect flux moderated both accuracy and bias of assumed similarity such that participants with higher flux manifested both greater tracking accuracy and larger bias of assumed similarity. Negative affect flux may be related to enhanced vigilance to close others' negative behavior, which may explain higher tracking accuracy and propensity to rely on a person's own negative behavior as a means of judging others' negative behavior. These processes may augment these individuals' negative interpersonal behavior, enhance cycles of negative social interactions, and lead to poor intrapersonal and interpersonal outcomes.

The cheater's high: the unexpected affective benefits of unethical behavior.

PubMed

Ruedy, Nicole E; Moore, Celia; Gino, Francesca; Schweitzer, Maurice E

2013-10-01

Many theories of moral behavior assume that unethical behavior triggers negative affect. In this article, we challenge this assumption and demonstrate that unethical behavior can trigger positive affect, which we term a "cheater's high." Across 6 studies, we find that even though individuals predict they will feel guilty and have increased levels of negative affect after engaging in unethical behavior (Studies 1a and 1b), individuals who cheat on different problem-solving tasks consistently experience more positive affect than those who do not (Studies 2-5). We find that this heightened positive affect does not depend on self-selection (Studies 3 and 4), and it is not due to the accrual of undeserved financial rewards (Study 4). Cheating is associated with feelings of self-satisfaction, and the boost in positive affect from cheating persists even when prospects for self-deception about unethical behavior are reduced (Study 5). Our results have important implications for models of ethical decision making, moral behavior, and self-regulatory theory.

Partnering with diabetes educators to improve patient outcomes

Diabetes is a chronic, progressive disease that affects millions worldwide. The paradigm of diabetes management has shifted to focus on empowering the person with diabetes to manage the disease successfully and to improve their quality of life. Diabetes self-management education is a collaborative process through which people with diabetes gain the knowledge and skills needed to modify their behavior and to self-manage successfully the disease and its related conditions. Diabetes educators are health care professionals who apply in-depth knowledge and skills in the biological and social sciences, communication, counseling, and pedagogy to enable patients to manage daily and future challenges. Diabetes educators are integral in providing individualized education and promoting behavior change, using a framework of seven self-care behaviors known as the AADE7 Self-Care Behaviors™, developed by the American Association of Diabetes Educators. The iterative process of promoting behavior change includes assessment, goal setting, planning, implementation, evaluation, and documentation. Diabetes educators work as part of the patient’s health care team to engage with the patient in informed, shared decision making. The increasing prevalence of diabetes and the growing focus on its prevention require strategies for providing people with knowledge, skills, and strategies they need and can use. The diabetes educator is the logical facilitator of change. Access to diabetes education is critically important; incorporating diabetes educators into more and varied practice settings will serve to improve clinical and quality of life outcomes for persons with diabetes.

Using Bayesian Nonparametric Hidden Semi-Markov Models to Disentangle Affect Processes during Marital Interaction

PubMed Central

Griffin, William A.; Li, Xun

2016-01-01

Sequential affect dynamics generated during the interaction of intimate dyads, such as married couples, are associated with a cascade of effects—some good and some bad—on each partner, close family members, and other social contacts. Although the effects are well documented, the probabilistic structures associated with micro-social processes connected to the varied outcomes remain enigmatic. Using extant data we developed a method of classifying and subsequently generating couple dynamics using a Hierarchical Dirichlet Process Hidden semi-Markov Model (HDP-HSMM). Our findings indicate that several key aspects of existing models of marital interaction are inadequate: affect state emissions and their durations, along with the expected variability differences between distressed and nondistressed couples are present but highly nuanced; and most surprisingly, heterogeneity among highly satisfied couples necessitate that they be divided into subgroups. We review how this unsupervised learning technique generates plausible dyadic sequences that are sensitive to relationship quality and provide a natural mechanism for computational models of behavioral and affective micro-social processes.

Ideology, affect, semiotics: towards a non-personal theory of personality.

PubMed

Larocco, Steve

2014-06-01

Personality theories, as Giordano (2014) argues, often treat Western versions of the self as having universal import. Eastern notions of self, however, offer a dramatically different basis for thinking about what personality might be. This paper, nonetheless, seeks to offer a general framework for theorizing about the epiphenomenon of personality in any culture, asserting that it is an effect of specific histories of ideological practices, semiotic networks and systems, and affect, which engage each other in dialogic and dialectical ways. The interactions of these factors, guided by ideology, regularize behavior and affective dynamics, largely in non-personal ways. Subjects are produced and reproduced from these complex interactions, which are situationally specific and simultaneously transpersonal. The subjects formed through these interactions are the basis for the folk psychology of personality, which treats the transient, varying effects of these interactions as more or less reified qualities that form a basis for the construction of selfhood, however conceived.

Decision aids can increase patient involvement in decision-making about health care. The study goal was to develop and test a decision aid for use by clinicians in discussion options for changing smoking behavior before and after elective surgery. In formative work, a decision aid was designed to facilitate patient-clinician discussion regarding three options: continue smoking, attempt a period of temporary abstinence, and attempt to quit smoking for good. A randomized, two-group pilot study was then conducted in smokers evaluated in preparation for elective surgery in a preoperative clinic to test the hypothesis that the decision aid would improve measures of decisional quality compared with usual care. The final decision aid consisted of three laminated cards. The front of each card included a colorful graphic describing each choice; the reverse including two to three pros and cons for each decision, a simple graphic illustrating the effects of smoking on the body, and a motivational phrase. In the randomized trial of 130 patients, the decision aid significantly (P < 0.05) improved measures of decisional quality and patient involvement in decision making (Cohen's d effect sizes of 0.76 and 1.20 for the Decisional Conflict Scale and Observing PatienT involvement In decisiON-making scale, respectively). However, the decision aid did not affect any aspect of perioperative smoking behavior, including the distribution of or adherence to choices. Although the use of a decision aid to facilitate clinician-patient discussions regarding tobacco use around the time of surgery substantially improved measures of decisional quality, it alone did not change perioperative tobacco use behavior.

US government-funded early home visiting services are expanding significantly. The most widely implemented home visiting models target at-risk new mothers and their infants. Such home visiting programs typically aim to support infant-parent relationships; yet, such programs' effects on infant attachment quality per se are as yet untested. Given these programs' aims, and the crucial role of early attachments in human development, it is important to understand attachment processes in home visited families. The current, preliminary study examined 94 high-risk mother-infant dyads participating in a randomized evaluation of the Healthy Families Durham (HFD) home visiting program. We tested (a) infant attachment security and disorganization as predictors of toddler behavior problems and (b) program effects on attachment security and disorganization. We found that (a) infant attachment disorganization (but not security) predicted toddler behavior problems and (b) participation in HFD did not significantly affect infant attachment security or disorganization. Findings are discussed in terms of the potential for attachment-specific interventions to enhance the typical array of home visiting services.

Behavioral health agencies have been encouraged to monitor performance and improve service quality. This paper characterizes the workforce charged with these tasks through a national survey of 238 behavioral health quality professionals. A latent class analysis suggests only 30 % of these workers report skills in both basic research and quality-specific skills. Respondents wanted to learn a variety of research and data analytic skills. The results call into question the quality of data collected in behavioral health agencies and the conclusions agencies are drawing from their data. Professional school and continuing education programs are needed to prepare this workforce.

Numerous treatments are available that address the core symptoms of posttraumatic stress disorder (PTSD). However, there are a number of related behavioral stress responses that are not assessed with PTSD measures, yet these behavioral stress responses affect quality of life. The goal of the current study was to investigate whether a recently developed measure of behavioral stress response, the Driving Behavior Survey (DBS), was sensitive to change associated with treatment among a group of participants diagnosed with PTSD. The DBS indexes anxious driving behavior, which is frequently observed among individuals with motor vehicle accident-related PTSD. Participants (n = 40) were racially-diverse adults (M age =40.78, 63% women) who met diagnostic criteria for motor vehicle accident-related PTSD. Hierarchical linear modeling analyses indicated that participants who were assigned to a brief, exposure-based intervention displayed significant reductions on the DBS subscales relative to participants assigned to the waitlist control condition (r = .41-.43). Moreover, meditational analyses indicated that the observed reductions on the DBS subscales were not better accounted for by reductions in PTSD. Taken together, these findings suggest that the DBS subscales are sensitive to changes associated with PTSD treatment and can be used to augment outcome measures in PTSD treatment trials PMID:24491201

During laser-arc hybrid welding, the welding direction exerts direct effects on the plasma properties, the transient behavior of the droplet, the weld pool behavior, and the temperature field. Ultimately, it will affect the welding process and the weld quality. However, the behavior of the CO2 laser+GMAW-P hybrid welding process has not been systematically studied. In this paper, the current-voltage characteristics of different welding processes were analyzed and compared. The dynamics of the droplet transfer, the plasma behavior, and the weld pool behavior were observed by using two high-speed camera systems. Moreover, an optical emission spectroscopy was applied to analyze the plasma temperature and the electron number density. The results indicated that the electrical resistance of the arc plasma reduced in the laser leading mode. For the same pulse duration, the metal transfer mode was the spray type with the laser leading arrangement. The temperature and electron density distribution showed bimodal behavior in the case of arc leading mode, while this phenomenon does not exist in the caser of laser leading mode. The double elliptic-planar distribution which conventional simulation process used was not applicable in the laser leading mode.

Objective Evaluate the effect of perceived health competence, a patient’s belief in his or her ability to achieve health-related goals, on health behavior and health-related quality of life. Methods We analyzed 2063 patients hospitalized with acute coronary syndrome and/or congestive heart failure at a large academic hospital in the United States. Multivariable linear regression models investigated associations between the two-item perceived health competence scale (PHCS-2) and positive health behaviors such as medication adherence and exercise (Health Behavior Index) as well as health-related quality of life (5-item Patient Reported Outcome Information Measurement System Global Health Scale). Results After multivariable adjustment, perceived health competence was highly associated with health behaviors (p<0.001) and health-related quality of life (p<0.001). Low perceived health competence was associated with a decrease in health-related quality of life between hospitalization and 90 days after discharge (p<0.001). Conclusions Perceived health competence predicts health behavior and health-related quality of life in patients hospitalized with cardiovascular disease as well as change in health-related quality of life after discharge. Practice implications Patients with low perceived health competence may be at risk for a decline in health-related quality of life after hospitalization and thus a potential target for counseling and other behavioral interventions.

Major floods adversely affect water quality through surface runoff, groundwater discharge, and damage to municipal water infrastructure. Despite their importance, it can be difficult to assess the effects of floods on streamwater chemistry because of challenges collecting samples and the absence of baseline data. This study documents water quality during the September 2013 extreme flood in the South Platte River, Colorado, USA. Weekly time-series water samples were collected from 3 urban source waters (municipal tap water, streamwater, and wastewater treatment facility effluent) under normal-flow and flood conditions. In addition, water samples were collected during the flood at 5 locations along the South Platte River and from 7 tributaries along the Colorado Front Range. Samples were analyzed for 54 major and trace elements. Specific chemical tracers, representing different natural and anthropogenic sources and geochemical behaviors, were used to compare streamwater composition before and during the flood. The results differentiate hydrological processes that affected water quality: (1) in the upper watershed, runoff diluted most dissolved constituents, (2) in the urban corridor and lower watershed, runoff mobilized soluble constituents accumulated on the landscape and contributed to stream loading, and (3) flood-induced groundwater discharge mobilized soluble constituents stored in the vadose zone.

Purpose To demonstrate that assessing quality of informal care involves more than merely determining whether care recipient needs for assistance with activities of daily living (ADLs) are satisfied on a routine basis. Potentially harmful behavior (PHB), adequate care, and exemplary care (EC) are conceptually distinct dimensions of quality of care. We investigated the extent to which these three dimensions also are empirically distinguishable. Design 237 care recipients completed the quality of care measures, and their caregivers completed psychosocial measures of depressed affect, life events, cognitive status, and perceived pre-illness relationship quality. Results Confirmatory factor analyses indicated that PHB, adequate care, and EC are empirically distinct factors. Although PHB was moderately related to EC, adequate care was not associated with PHB and was only slightly related to EC. Psychosocial variables were not related to adequate care but were differentially associated with PHB and EC, providing further evidence for the distinction between the measures of quality of care used in this study. Conclusions Assessing quality of informal care is a complex endeavor. ADL assistance can be adequate in the presence of PHB and/or the absence of EC. Declines in EC may signal increases in PHB, independent of adequacy of care. These findings produce a brief, portable, and more comprehensive instrument for assessing quality of informal care.

Positive technology: using interactive technologies to promote positive functioning.

It is generally assumed that technology assists individuals in improving the quality of their lives. However, the impact of new technologies and media on well-being and positive functioning is still somewhat controversial. In this paper, we contend that the quality of experience should become the guiding principle in the design and development of new technologies, as well as a primary metric for the evaluation of their applications. The emerging discipline of Positive Psychology provides a useful framework to address this challenge. Positive Psychology is the scientific study of optimal human functioning and flourishing. Instead of drawing on a "disease model" of human behavior, it focuses on factors that enable individuals and communities to thrive and build the best in life. In this paper, we propose the "Positive Technology" approach--the scientific and applied approach to the use of technology for improving the quality of our personal experience through its structuring, augmentation, and/or replacement--as a way of framing a suitable object of study in the field of cyberpsychology and human-computer interaction. Specifically, we suggest that it is possible to use technology to influence three specific features of our experience--affective quality, engagement/actualization, and connectedness--that serve to promote adaptive behaviors and positive functioning. In this framework, positive technologies are classified according to their effects on a specific feature of personal experience. Moreover, for each level, we have identified critical variables that can be manipulated to guide the design and development of positive technologies.

During adolescence, problems reflecting cognitive, behavioral and affective dysregulation, such as inattention and emotional dyscontrol, have been observed to be associated with substance use disorder (SUD) risks and outcomes. Prior studies have typically been with small samples, and have typically not included comprehensive measurement of executive dysfunction domains. The relationships of executive dysfunction in daily life with performance based testing of cognitive skills and structural brain characteristics, thought to be the basis for executive functioning, have not been definitively determined. The aims of this study were to determine the relationships between executive dysfunction in daily life, measured by the Behavior Rating Inventory of Executive Function (BRIEF), cognitive skills and structural brain characteristics, and SUD risks, including a global SUD risk indicator, sleep quality, and risky alcohol and cannabis use. In addition to bivariate relationships, multivariate models were tested. The subjects (n = 817; ages 12 through 21) were participants in the National Consortium on Alcohol and Neurodevelopment in Adolescence (NCANDA) study. The results indicated that executive dysfunction was significantly related to SUD risks, poor sleep quality, risky alcohol use and cannabis use, and was not significantly related to cognitive skills or structural brain characteristics. In multivariate models, the relationship between poor sleep quality and risky substance use was mediated by executive dysfunction. While these cross-sectional relationships need to be further examined in longitudinal analyses, the results suggest that poor sleep quality and executive dysfunction may be viable preventive intervention targets to reduce adolescent substance use.

This meta-analysis reviewed 126 published empirical articles over the past 50 years describing associations between marital relationship quality and physical health in over 72,000 individuals. Health outcomes included clinical endpoints (objective assessments of function, disease severity, and mortality; subjective health assessments) and surrogate endpoints (biological markers that substitute for clinical endpoints, such as blood pressure). Biological mediators included cardiovascular reactivity and hypothalamic-pituitary-adrenal axis activity. Greater marital quality was related to better health, with mean effect sizes from r = .07 to .21, including lower risk of mortality, r = .11, and lower cardiovascular reactivity during marital conflict, r = −.13, but not daily cortisol slopes or cortisol reactivity during conflict. The small effect sizes were similar in magnitude to previously found associations between health behaviors (e.g., diet) and health outcomes. Effect sizes for a small subset of clinical outcomes were susceptible to publication bias. In some studies, effect sizes remained significant after accounting for confounds such as age and socioeconomic status. Studies with a higher proportion of women in the sample demonstrated larger effect sizes, but we found little evidence for gender differences in studies that explicitly tested gender moderation, with the exception of surrogate endpoint studies. Our conclusions are limited by small numbers of studies for specific health outcomes, unexplained heterogeneity, and designs that limit causal inferences. These findings highlight the need to explicitly test affective, health behavior, and biological mechanisms in future research, and focus on moderating factors that may alter the relationship between marital quality and health.

Interferometric characterization of tear film dynamics

NASA Astrophysics Data System (ADS)

Primeau, Brian Christopher

The anterior refracting surface of the eye is the thin tear film that forms on the surface of the cornea. When a contact lens is on worn, the tear film covers the contact lens as it would a bare cornea, and is affected by the contact lens material properties. Tear film irregularity can cause both discomfort and vision quality degradation. Under normal conditions, the tear film is less than 10 microns thick and the thickness and topography change in the time between blinks. In order to both better understand the tear film, and to characterize how contact lenses affect tear film behavior, two interferometers were designed and built to separately measure tear film behavior in vitro and in vivo. An in vitro method of characterizing dynamic fluid layers applied to contact lenses mounted on mechanical substrates has been developed using a phase-shifting Twyman-Green interferometer. This interferometer continuously measures light reflected from the surface of the fluid layer, allowing precision analysis of the dynamic fluid layer. Movies showing this fluid layer behavior can be generated. The fluid behavior on the contact lens surface is measured, allowing quantitative analysis beyond what typical contact angle or visual inspection methods provide. The in vivo interferometer is a similar system, with additional modules included to provide capability for human testing. This tear film measurement allows analysis beyond capabilities of typical fluorescein visual inspection or videokeratometry and provides better sensitivity and resolution than shearing interferometry methods.

Cognitive and behavioral effects of obstructive sleep apnea syndrome in children: a systematic literature review.

Obstructive sleep apnea syndrome (OSA) is a common respiratory sleep disorder in children that is believed to adversely affect both quality of life and cognition. The purpose of the present systematic review was to obtain evidence of the impact of OSA on children's cognitive/behavioral abilities from primary studies published in MEDLINE/PubMed, LILACS, SciELO, ISI Web of Science, and PsycINFO databases from 2002 to 2016. Of the 649 articles found, only 34 met the eligibility criteria: studies that evaluated cognition, behavior, and/or academic achievement of children meeting clinical criteria for OSA to compare their data to those of healthy controls or normative data, provided that the samples did not present conditions that might affect cognition/behavior irrespective of OSA. The few selected articles with low risk of bias (levels of evidence I and II) showed that OSA children's intellectual abilities may be impaired but remain within the normal range. Which specific cognitive ability drives this impairment is unclear, as there was insufficient evidence of deficits in language, memory, attention, executive functions, and academic performance, due to low levels of evidence, conflicting findings, and/or heterogeneity of tasks and cognitive abilities tapped by the measures used to assess these domains. To determine why this is so, future studies must test OSA patients using measures that allow for fractionated higher- and lower-order cognitive abilities based on accepted cognitive neuropsychology models.

(1) To assess the prevalence of rural primary care physician (PCP) bypass, a behavior in which residents travel farther than necessary to obtain health care, (2) To examine the role of community and non-health-care-related characteristics on bypass behavior, and (3) To analyze spatial bypass patterns to determine which rural communities are most affected by bypass. Data came from the Montana Health Matters survey, which gathered self-reported information from Montana residents on their health care utilization, satisfaction with health care services, and community and demographic characteristics. Logistic regression and spatial analysis were used to examine the probability and spatial patterns of bypass. Overall, 39% of respondents bypass local health care. Similar to previous studies, dissatisfaction with local health care was found to increase the likelihood of bypass. Dissatisfaction with local shopping also increases the likelihood of bypass, while the number of friends in a community, and commonality with community reduce the likelihood of bypass. Other significant factors associated with bypass include age, income, health, and living in a highly rural community or one with high commuting flows. Our results suggest that outshopping theory, in which patients bundle services and shopping for added convenience, extends to primary health care selection. This implies that rural health care selection is multifaceted, and that in addition to perceived satisfaction with local health care, the quality of local shopping and levels of community attachment also influence bypass behavior. © 2014 National Rural Health Association.

The current study examines the relationship of affect and eating disorder behavior in anorexia nervosa (AN) using ecological momentary assessment. Participants were 118 adult females recruited at three sites from eating disorder treatment centers and community advertisements. All participants met full DSM-IV criteria or sub-threshold criteria for AN. Participants were provided handheld computers and asked to report positive affect, negative affect, loss of control (LOC) eating, purging, exercise, drinking fluids to curb appetite, and weighing one's self multiple times per day as well as dietary restriction once daily over a two-week interval. Mixed-effects models were used to examine the extent to which affective states predict dietary restriction. Additionally, we used two analytic approaches to compare affect prior to and after other eating disorder behaviors. We found that higher daily ratings of negative affect were associated with a greater likelihood of dietary restriction on subsequent days. When examining the single rating immediately before and after behaviors, we found that negative affect increased significantly following LOC eating, purging, the combination of LOC and eating/purging, and weighing of one's self. Using this same analytic approach we also found negative affect to decrease significantly following the consumption of fluids to curb appetite and exercise. When examining the covariation of AN behaviors and negative affect assessed multiple times in the hours and minutes before the behaviors, we found negative affect significantly increased prior to LOC eating, purging, the combination of LOC eating/and purging, and weighing behavior. Negative affect also significantly decreased following the occurrence of these behaviors. These findings are consistent with the idea that that negative affect is potentially a critical maintenance mechanism of some AN symptoms, but that the analytic approach used to examine affect and behavior may have significant implications on the interpretation of findings.

Based on psychological and neurobiological theories of core affective experience, we identify a set of direct and indirect paths through which affective feelings at work affect three dimensions of behavioral outcomes: direction, intensity, and persistence. First, affective experience may influence these behavioral outcomes indirectly by affecting goal level and goal commitment, as well as three key judgment components of work motivation: expectancy judgments, utility judgments, and progress judgments. Second, affective experience may also affect these behavioral outcomes directly. We discuss implications of our model. PMID:16871321

Mold flux plays very important roles in the continuous casting process, and its high-temperature properties affect the quality of the final as-cast product greatly. Investigations on the melting, isothermal and nonisothermal crystallization, and phase evolution behaviors under a simulated temperature field for the mold flux system using the single/double hot-thermocouple technique (S/DHTT) were reviewed. Meanwhile, further in situ observations on the wetting behavior and heat transfer ability of the mold flux system were also carried out using the S/DHTT. The results summarized here provide a clear understanding of both the high-temperature properties of mold flux and the detailed application of advanced real-time visual high-temperature S/DHTT to this molten slag system.

This study examined cross-ethnic friendship choices and intergroup attitudes in a sample of 762 sixth grade Asian American students (Mage=11.5 years) attending one of 19 middle schools that varied in ethnic composition. Multiple measures of friendship (quantity and quality) and intergroup attitudes (affective, cognitive, behavioral) toward White, Latino, and Black grademates were assessed. The results showed that Asian American students over-nominated White students and under-nominated Latino and Black students as their friends when school availability of each ethnic group was accounted for. Cross-ethnic friendships were related to better intergroup attitudes, especially the behavioral dimension of attitudes. Cross-ethnic friendships were least likely to change attitudes towards Blacks. Implications for future research, educational practice, and attitude intervention programs were discussed. PMID:25626492

This paper presents the results obtained with a new ball burnishing tool developed for the mechanical treatment of large flat surfaces. Several parameters can affect the mechanical behavior and fatigue of workpiece. Our study focused on the effect of the burnishing force on the surface quality and on the service properties (mechanical behavior, fatigue) of AISI 1010 steel hot-rolled plates. Experimental results assert that burnishing force not exceeding 300 N causes an increase in the ductility. In addition, results indicated that the effect of the burnishing force on the residual surface stress was greater in the direction of advance than in the cross-feed direction. Furthermore, the flat burnishing surfaces did not improve the fatigue strength of AISI 1010 steel flat specimens.

The Nencki Affective Picture System (NAPS; Marchewka, Żurawski, Jednoróg, & Grabowska, Behavior Research Methods, 2014) is a standardized set of 1,356 realistic, high-quality photographs divided into five categories (people, faces, animals, objects, and landscapes). NAPS has been primarily standardized along the affective dimensions of valence, arousal, and approach-avoidance, yet the characteristics of discrete emotions expressed by the images have not been investigated thus far. The aim of the present study was to collect normative ratings according to categorical models of emotions. A subset of 510 images from the original NAPS set was selected in order to proportionally cover the whole dimensional affective space. Among these, using three available classification methods, we identified images eliciting distinguishable discrete emotions. We introduce the basic-emotion normative ratings for the Nencki Affective Picture System (NAPS BE), which will allow researchers to control and manipulate stimulus properties specifically for their experimental questions of interest. The NAPS BE system is freely accessible to the scientific community for noncommercial use as supplementary materials to this article.

To evaluate patient satisfaction of service at the Menopause Clinic and to identify factors affecting patient satisfaction. Cross sectional descriptive study was conducted at the Menopause Clinic, Maharaj Nakorn Chiang Mai hospital. Three hundred twenty six subjects were included. The questionnaire consists of two parts, demographic and patient satisfaction. The patient satisfaction was evaluated in five aspects. The overall patient satisfaction level was good (mean 4.2 +/- 0.71). The satisfactions about service behavior quality of care and health information were in excellent level (mean 4.29 +/- 0.69, 4.25 +/- 0.65, and 4.26 +/- 0.69, respectively). The satisfaction about clinic facilities/conveniences and medical expense were in good level (mean 3.83 +/- 0.79 and 3.87 +/- 0.75). There are three variables that could affect patient satisfaction: Occupation and level of education affected satisfaction in medical expense aspect (p < 0.001 and p < 0.05) and number of visits affected the clinic facilities/convenience aspect (p < 0.05). Some patient characteristics affected the patient satisfaction. However, system and structure of service in different setting hospitals are of concerned.

Predator evasion in zooplankton is suppressed by polyunsaturated fatty acid limitation.

Brzeziński, Tomasz; von Elert, Eric

Herbivorous zooplankton avoid size-selective predation by vertical migration to a deep, cold water refuge. Adaptation to low temperatures in planktonic poikilotherms depends on essential dietary lipids; the availability of these lipids often limits growth and reproduction of zooplankton. We hypothesized that limitation by essential lipids may affect habitat preferences and predator avoidance behavior in planktonic poikilotherms. We used a liposome supplementation technique to enrich the green alga Scenedesmus obliquus and the cyanobacterium Synecchococcus elongatus with the essential lipids, cholesterol and eicosapentaenoic acid (EPA), and an indoor system with a stratified water-column (plankton organ) to test whether the absence of these selected dietary lipids constrains predator avoidance (habitat preferences) in four species of the key-stone pelagic freshwater grazer Daphnia. We found that the capability of avoiding fish predation through habitat shift to the deeper and colder environment was suppressed in Daphnia unless the diet was supplemented with EPA; however, the availability of cholesterol did not affect habitat preferences of the tested taxa. Thus, their ability to access a predator-free refuge and the outcome of predator-prey interactions depends upon food quality (i.e. the availability of an essential fatty acid). Our results suggest that biochemical food quality limitation, a bottom-up factor, may affect the top-down control of herbivorous zooplankton.

Endometriosis is a hormone-dependent, inflammatory, painful condition affecting 1 in 10 women during their reproductive years. The symptoms of endometriosis-dysmenorrhea, dyspareunia, infertility-negatively impact the quality of life (QoL) of the affected women. Few studies have been conducted on mental health and QoL impact in a younger endometriosis patient population (adolescents and young women). This study quantitative, cross-sectional study was designed to address this gap by ascertaining whether coping strategies may impact the QoL of this patient population. After consent, participants (n = 24) completed a sociodemographic questionnaire, Beck Anxiety Inventory (BAI), Beck Depression Inventory II (BDI-II), Coping Strategies Inventory (CSI), Endometriosis Health Patient-5 (EHP-5) and Visual Analogue Scale (VAS). Participants reported the use of both positive and maladaptive strategies to deal with the symptomatology, which were associated with QoL levels and mental health status. Associations between QoL and maladaptive coping strategies (e.g. autocriticism, social withdrawal) were uncovered. Cognitive restructuring was identified as an adaptive coping strategy that impacts QoL positively. These results provide additional evidence showing that endometriosis symptoms substantially affect the psychological well-being of young patients and identify opportunities for interventions (e.g. cognitive behavioral, rational/emotive therapy) to implement coping styles leading to improved QoL.

The present study examines the relationship between hard drug use in high school and occupational and job quality outcomes measured at approximately age 29. We use two different methods aimed at ruling out the possibility of spurious correlations between high school drug use and occupational outcomes: (1) directly controlling for pre-high school characteristics that may affect both high school drug use and later occupational characteristics (e.g., educational orientation, early drug use and deviant behavior); and (2) matching high school users with a subset of nonusers that have very similar characteristics and then estimating the difference in labor market outcomes for these two groups (i.e., propensity score matching). Overall, the results suggest that adolescent drug use is linked with poorer occupational and job quality outcomes as much as 10 years after high school. Interestingly, which job-related outcomes are affected by early hard drug use varies by gender. Females who use hard drugs as adolescents end up in lower skill, lower status jobs while males who use hard drugs as adolescents are more likely to end up in jobs with fewer benefits (e.g., health, retirement).

Evaluations of behavior change interventions aimed at improving professional practice are increasingly focused on impacts at the practice and patient outcome levels. Many of these evaluations assume that if the intended changes occur, the result represents an improvement. However, given the systemic nature of clinical practice, a change in one area can produce changes in other areas as well, some of which may adversely affect the patient. Balancing measures are used to determine whether unintended consequences of an intervention have been introduced into other areas of the system. The aims of this study were to evaluate the impact of behavior change intervention-based continuing professional development (CPD) on pharmacist interventions (resolution of drug therapy problems-DTPs) and resolution of quality indicator DTPs and knowledge change for urinary tract infections (UTI) and pneumonia. As a balancing measure, we aimed to determine whether delivery of behavior change interventions targeting pneumonia and UTI practice results in a negative impact on other important pharmacist interventions, specifically the resolution of heart failure DTPs. A quasiexperimental study was conducted at a Canadian health authority that evaluated the impacts of an 8-week multifaceted behavior change intervention delivered to 58 ward-based pharmacists. The primary outcome was change in proportion of UTI and pneumonia DTPs resolved from the 6-month preintervention to 6-month postintervention phase. Secondary outcomes were changes in proportion of UTI and pneumonia quality indicator DTPs resolved, knowledge quiz scores, and proportion of quality indicator DTPs resolved for heart failure as a balancing measure. A total of 58 pharmacists were targets of the intervention. The proportion of resolved UTI and pneumonia DTPs increased from 17.8 to 27.2% (relative risk increase 52.8%, 95% confidence interval [CI] 42.8-63.6%; P < 0.05). The proportion of resolved UTI and pneumonia quality indicator DTPs increased from 12.2% to 18.2% (relative risk increase 49.9%, 95% CI 34.5-67.0%; P < 0.05). Resolved heart failure DTPs decreased from 14.3 to 8.5% (RRR 40.4%, 95% CI 33.9-46.2%; P < 0.05). Thirty-six pharmacists completed the pre- and post-quiz. Scores increased from 11.3/20 ± 3.2/20 to 14.8/20 ± 2.9/20 (P < 0.05). CPD using a multifaceted behavior change intervention improved pharmacist behavior and knowledge for UTI and pneumonia. However, these improvements may be offset by reduced interventions for other disease states, such as heart failure. Strategies to mitigate the unintended effects on other professional behaviors should be implemented when delivering CPD focused on changing one aspect of professional behavior.

We prospectively investigated the effect of child hyperactive/impulsive, inattentive, and oppositional/defiant behaviors on the development of youth antisocial behaviors, and the moderating influence of gender and the parent-child relationship quality in a normative sample. Participants (N = 673, 50 % girls) were assessed at 10 years of age (parent reports) and at age 15 (parent and adolescent reports). Using latent change models, we found that initial levels of, as well as increases in, hyperactivity/impulsivity and oppositional behaviors and initial levels of inattention behaviors predicted youth antisocial behaviors. The increase in oppositional behaviors was predictive of youth antisocial behaviors in girls only. Child hyperactive/impulsive behaviors predicted youth antisocial behaviors only in children for whom the quality of the parent-child relationship deteriorated from childhood to adolescence. Thus, both initial levels of and increases in disruptive behaviors as well as gender are important for understanding the development of antisocial behaviors in adolescence. We received partial support for the hypothesized, moderating role of a high-quality parent-child relationship.

The goal of this review was to evaluate the effectiveness of public reporting of health care quality information as a quality improvement strategy. We sought to determine if public reporting results in improvements in health care delivery and patient outcomes. We also considered whether public reporting affects the behavior of patients or of health care providers. Finally we assessed whether the characteristics of the public reports and the context affect the impact of public reports. Articles available between 1980 and 2011 were identified through searches of the following bibliographical databases: MEDLINE®, Embase, EconLit, PsychINFO, Business Source Premier, CINAHL, PAIS, Cochrane Database of Systematic Reviews, EPOC Register of Studies, DARE, NHS EED, HEED, NYAM Grey Literature Report database, and other sources (experts, reference lists, and gray literature). We screened citations based on inclusion and exclusion criteria developed based on our definition of public reporting. We initially did not exclude any studies based on study design. Of the 11,809 citations identified through title and abstract triage, we screened and reviewed 1,632 articles. A total of 97 quantitative and 101 qualitative studies were included, abstracted, entered into tables, and evaluated. The heterogeneity of outcomes as well as methods prohibited formal quantitative synthesis. Systematic reviews were used to identify studies, but their conclusions were not incorporated into this review. For most of the outcomes, the strength of the evidence available to assess the impact of public reporting was moderate. This was due in part to the methodological challenges researchers face in designing and conducting research on the impact of population-level interventions. Public reporting is associated with improvement in health care performance measures such as those included in Nursing Home Compare. Almost all identified studies found no evidence or only weak evidence that public reporting affects the selection of health care providers by patients or their representatives. Studies of health care providers' response to public reports suggest they engage in activities to improve quality when performance data are made public. Characteristics of public reports and the context, which are likely to be important when considering the diffusion of quality improvement activities, were rarely studied or even described. The heterogeneity of the outcomes and the moderate strength of evidence for most outcomes make it difficult to draw definitive conclusions. However, some observations were supported by existing research. Public reporting is more likely to be associated with changes in health care provider behaviors than with selection of health services providers by patients or families. Quality measures that are publicly reported improve over time. Although the potential for harms is frequently cited by commentators and critics of public reporting, the amount of research on harms is limited and most studies do not confirm the potential harm.

Benefits of transformational behaviors for leaders: A daily investigation of leader behaviors and need fulfillment.

Although a large body of work has examined the benefits of transformational leadership, this work has predominantly focused on recipients of such behaviors. Recent research and theory, however, suggest that there are also benefits for those performing behaviors reflective of transformational leadership. Across 2 experience-sampling studies, we investigate the effects of such behaviors on actors' daily affective states. Drawing from affective events theory and self-determination theory we hypothesize and find that engaging in behaviors reflective of transformational leadership is associated with improvement in actors' daily affect, more so than engaging in behaviors reflective of transactional, consideration, initiating structure, and participative leadership. Behaviors reflective of transformational leadership improved actors' affect in part by fulfilling their daily needs. Furthermore, extraversion and neuroticism moderated these effects such that extraverts benefitted less whereas neurotics benefitted more from these behaviors in terms of affective changes. We consider the theoretical and practical implications of these findings and offer directions for future research. (c) 2016 APA, all rights reserved).

Person-centered care is a critical component of quality care, essential to enable treatment adherence, and maximize health outcomes. Improving the quality of health services is a key strategy to achieve the new global target of zero preventable maternal deaths by 2030. Recognizing this, the Government of India has in the last decade initiated a number of strategies to address quality of care in health and family welfare services. We conducted a policy review of quality improvement strategies in India from 2005 to 15, covering three critical areas- maternal and newborn health, family planning, and abortion (MNHFP + A). Based on Walt and Gilson's policy triangle framework, we analyzed the extent to which policies incorporated person-centered care, while identifying unaddressed issues. Data was sourced from Government of India websites, scientific and grey literature databases. Twenty-two national policy documents, comprising two policy statements and 20 implementation guidelines of specific schemes were included in the review. Quality improvement strategies span infrastructure, commodities, human resources, competencies, and accountability that are driving quality assurance in MNHFP + A services. However, several implementation challenges have affected compliance with person-centered care, thereby affecting utilization and outcomes. Focus on person-centered care in Indian MNHFP + A policy has increased in recent years. Nevertheless, some aspects must still be strengthened, such as positive interpersonal behavior, information sharing and promptness of care. Implementation can be improved through better provider training, patient feedback and monitoring mechanisms. Moreover, unless persisting structural challenges are addressed implementation of person-centered care in facilities will not be effective.

We sought to determine whether the exposure to the sub-concussive blows that occur during division III collegiate collision sports affect later life neurobehavioral quality-of-life measures. We conducted a cross-sectional study of alumni from four division III colleges, targeting those between the ages of 40-70 years, using several well-validated quality-of-life measures for executive function, general concerns, anxiety, depression, emotional and behavior dyscontrol, fatigue, positive affect, sleep disturbance, and negative consequences of alcohol use. We used multivariable linear regression to assess for associations between collision sport participation and quality-of-life measures while adjusting for covariates including age, gender, race, annual income, highest educational degree, college grades, exercise frequency, and common medical conditions. We obtained data from 3702 alumni, more than half of whom (2132) had participated in collegiate sports, 23% in collision sports, 23% in non-contact sports. Respondents with a history of concussion had worse self-reported health on several measures. When subjects with a history of concussion were removed from the analyses in order to assess for any potential effect of sub-concussive blows alone, negative consequences of alcohol use remained higher among collision sport athletes (β-coefficient 1.957, 95% CI 0.827-3.086). There were, however, no other significant associations between exposure to collision sports during college and any other quality-of-life measures. Our results suggest that, in the absence of a history of concussions, participation in collision sports at the Division III collegiate level is not a risk factor for worse long-term neurobehavioral outcomes, despite exposure to repeated sub-concussive blows.

Predictors of the Health-Promoting Behaviors of Nepalese Migrant Workers.

Health-promoting behaviors assist individuals to prevent disease, promote health, increase longevity, and enjoy a better quality of life. A number of interpersonal, social, and environmental factors have been shown to influence health-promoting behaviors. Little empirical evidence exists about the predictors of health-promoting behaviors among migrant workers. This study uses Pender's health promotion model to describe and identify the predictors of health-promoting behaviors in Nepalese migrant workers in Korea. A cross-sectional research design was used. Nepalese migrants who had been working in South Korea (n = 169) for over 6 months were surveyed between July and December 2012. Self-efficacy was measured using the Perceived Health Competence Scale, the Health-Promoting Lifestyle Profile II was used to measure health-promoting lifestyle behaviors, and perceived health status was measured using a single-item question. Descriptive statistics, correlation analysis, and multiple regression analysis were used to analyze data. Spiritual activity was the highest reported health-promoting behavior, whereas physical activity was the least practiced behavior. Self-efficacy was the only significant predictor of health-promoting behavior. The results of this study suggest that future health-promoting interventions should enhance the self-efficacy of target populations for individual health behaviors. Factors such as working conditions, culture, and economic background that may affect the health-promoting behaviors of migrant workers must be considered when planning nursing interventions. Multicultural nursing structures and policies are needed to reach out proactively to all adult migrant groups.

5-HTTLPR and gender differences in affective disorders: A systematic review.

2016-01-15

Serotonin transporter-linked polymorphic region (5-HTTLPR) variants have been extensively studied in psychiatric disorders. Although gender effects have been reported, they have not been comprehensively reviewed. The aim of our study was to summarize literature findings on 5-HTTLPR and gender differences in affective disorders. A systematic search of PubMed, ISI Web of Knowledge, and PsycINFO databases was performed for dates until January 2015. The included articles (n=78) analyzed the association between 5-HTTLPR and affective spectrum disorders, taking into account gender. The quality of each study was assessed through STROBE and CONSORT. 5-HTTLPR modulation of affective disorders varied by gender. The S allele (or SS genotype) seemed to be differently associated with an increased risk of depression, depressive symptoms, anxiety traits and symptoms, and symptoms of internalizing behavior among women and an increased risk of aggressiveness, conduct disorder and symptom counts of externalizing behavior among men. Moreover, the presence of stressful life events reinforced the association. Interestingly, these differences seemed to begin with adolescence and were not consistent among the elderly, suggesting a plausible role of hormonal fluctuations. The review is limited by the small number of included papers, due to the paucity of information in the literature regarding 5-HTTLPR and gender. 5-HTTLPR variants may exert a differential modulation on a number of features depending on gender. Further studies are needed to more deeply investigate the effect of 5-HTTLPR×gender on the modulation of affective disorders. Copyright © 2015 Elsevier B.V. All rights reserved.

Sleep problems are frequently addressed as a primary or secondary concern during the visit to the pediatric neurology clinic. Sleep disorders can mimic other neurologic diseases (e.g., epilepsy and movement disorders), and this adds challenges to the diagnostic process. Sleep disorders can significantly affect the quality of life and functionality of children in general and those with comorbid neurological diseases in particular. Understanding the pathophysiology of sleep disorders, recognizing the implications of sleep disorder in children with neurologic diseases and behavioral difficulties, and early intervention continue to evolve resulting in better neurocognitive outcomes.

Studies suggest that the quality of parent-adolescent communication about sex uniquely predicts adolescent sexual behavior. Previous studies have relied predominantly on self-report data. Observational methods, which are not susceptible to self-report biases, may be useful in examining the associations between the quality of parent-adolescent communication about sex and adolescent sexual behavior more objectively. With a sample of adolescents (N = 55, 58% male, 44% white, Mage = 15.8) and their parents, we used hierarchical logistic regression analyses to examine the associations between the observed quality of parent-adolescent communication about dating and sex and the likelihood of adolescents' sexual intercourse. The quality of parent-adolescent communication about dating and sex predicted sexual behavior. Specifically, lecturing was associated with a higher likelihood of adolescents having had sexual intercourse. The quality of parent-adolescent communication about sex is a unique correlate of adolescent sexual behavior and warrants further investigation. Thus, it serves as a potential target of preventive interventions that aim to foster adolescent sexual health behaviors. Copyright © 2015 Society for Adolescent Health and Medicine.

Studies that have examined the association between parenting behaviors and childhood post-traumatic stress disorder (PTSD) have yielded mixed findings. To clarify the role of parenting in childhood PTSD we conducted a systematic review and meta-analysis of 14 studies that investigated the association between parenting and youth PTSD symptoms (total n=4010). Negative parenting behaviors (e.g. overprotection, hostility) accounted for 5.3% of the variance in childhood PTSD symptoms. Positive parenting behaviors (e.g. warmth, support) account for 2.0% of variance. The negative and positive parenting and child PTSD symptom associations did not statistically differ in magnitude. Moderator analyses indicated that methodological factors and trauma variables may affect the association between parenting and child PTSD. Most studies relied upon questionnaire measures of general parenting style, and studies were predominantly cross-sectional with weaker evidence found in longitudinal studies. Given the small number of high quality studies available, only provisional recommendations about the role of parenting in childhood PTSD are made. Copyright © 2017 The Authors.

In order to improve the quality and performance of healthcare services, healthcare information technology is among the most important technology in healthcare supply chain management. This study sets out to apply and test the Unified Theory of Acceptance and Use of Technology (UTAUT), to examine the factors influencing healthcare Information Technology (IT) services. A structured questionnaire was developed and distributed to healthcare representatives in each province surveyed in Thailand. Data collected from 400 employees including physicians, nurses, and hospital staff members were tested the model using structural equation modeling technique. The results found that the factors with a significant effect are performance expectancy, effort expectancy and facilitating conditions. They were also found to have a significant impact on behavioral intention to use the acceptance healthcare technology. In addition, in Thai provincial areas, positive significance was found with two factors: social influence on behavioral intention and facilitating conditions to direct using behavior. Based on research findings, in order for healthcare information technology to be widely adopted and used by healthcare staffs in healthcare supply chain management, the healthcare organizational management should improve healthcare staffs' behavioral intention and facilitating conditions.

Objective After surgery for breast cancer, many women experience anxiety relating to the cancer that can adversely affect quality of life and emotional functioning during the year postsurgery. Symptoms such as intrusive thoughts may be ameliorated during this period with a structured, group-based cognitive behavior intervention. Method A 10-week group cognitive behavior stress management intervention that included anxiety reduction (relaxation training), cognitive restructuring, and coping skills training was tested among 199 women newly treated for stage 0-III breast cancer. They were then followed for 1 year after recruitment. Results The intervention reduced reports of thought intrusion, interviewer ratings of anxiety, and emotional distress across 1 year significantly more than was seen with the control condition. The beneficial effects were maintained well past the completion of adjuvant therapy. Conclusions Structured, group-based cognitive behavior stress management may ameliorate cancer-related anxiety during active medical treatment for breast cancer and for 1 year following treatment. Group-based cognitive behavior stress management is a clinically useful adjunct to offer to women treated for breast cancer. PMID:17012691

2012-01-01

Since the original characterization of the ventral visual pathway our knowledge of its neuroanatomy, functional properties, and extrinsic targets has grown considerably. Here we synthesize this recent evidence and propose that the ventral pathway is best understood as a recurrent occipitotemporal network containing neural representations of object quality both utilized and constrained by at least six distinct cortical and subcortical systems. Each system serves its own specialized behavioral, cognitive, or affective function, collectively providing the raison d’etre for the ventral visual pathway. This expanded framework contrasts with the depiction of the ventral visual pathway as a largely serial staged hierarchy that culminates in singular object representations for utilization mainly by ventrolateral prefrontal cortex and, more parsimoniously than this account, incorporates attentional, contextual, and feedback effects.

Mattress, as a sleep platform, its types and physical properties has an important effect on sleep quality and rest efficiency. In this paper, by subjective evaluations, analysis of sleeping behaviors and tests of depth of sleep, the relationship between characteristics of the bedding materials, the structure of mattress, sleep quality and sleep behaviors were studied. The results showed that: (1) Characteristics of the bedding materials and structure of spring mattress had a remarkable effect on sleep behaviors and sleep quality. An optimum combination of the bedding materials, the structure of mattress and its core could improve the overall comfort of mattress, thereby improving the depth of sleep and sleep quality. (2) Sleep behaviors had a close relationship with sleeping postures and sleep habits. The characteristics of sleep behaviors vary from person to person.

Quality of peer relationships and perceived peer antisocial behavior were examined as moderators of the link between negative parenting and externalizing behavior problems in school from middle childhood to early adolescence. Data on negative parenting (i.e., unilateral parental decision making, low supervision and awareness, and harsh discipline) were collected from 362 parents in the summer preceding the adolescents’ entry into Grade 6. Adolescent reports of positive peer relationships and peer antisocial behavior were assessed in the winter of Grade 7. The outcome measure was teacher report of adolescent externalizing behavior in the spring of Grade 7, controlling for externalizing behavior in Grade 5. High levels of friendship quality and peer group affiliation attenuated the association between unilateral parental decision making and adolescent externalizing behavior in school; this was particularly true when adolescents associated with peers perceived to be low in antisocial behavior. In addition, having low-quality peer relationships and having peers perceived to be highly antisocial further amplified the association between unilateral parental decision making and adolescent externalizing behavior problems. Finally, high levels of friend and peer group antisocial behavior exacerbated the predictiveness of harsh discipline for adolescents’ externalizing behavior. PMID:20209019

The burdens related to mental illness have been increasingly recognized in many countries. Nevertheless, research in positive mental health behaviors remains scarce. This study utilizes the Predisposing, Reinforcing, and Enabling Causes in Education Diagnosis and Evaluation (PRECEDE) model to identify factors associated with mental health promoting behaviors and to examine the effects of these behaviors on mental well-being and quality of life among 941 adults in Hong Kong. Structural equation modeling shows that sense of coherence (predisposing factor), social support (reinforcing factor), and daily hassles (enabling factor) are significantly related to mental health promoting behaviors, which are associated with mental well-being and quality of life. Results of bootstrap analyses confirm the mediating role of mental health promoting behaviors on well-being and quality of life. The study supports the application of the PRECEDE model in understanding mental health promoting behaviors and demonstrates its relationships with well-being and quality of life.

Reciprocal effects among changes in weight, body image, and other psychological factors during behavioral obesity treatment: a mediation analysis.

Changes in body image and subjective well-being variables (e.g. self-esteem) are often reported as outcomes of obesity treatment. However, they may, in turn, also influence behavioral adherence and success in weight loss. The present study examined associations among obesity treatment-related variables, i.e., change in weight, quality of life, body image, and subjective well-being, exploring their role as both mediators and outcomes, during a behavioral obesity treatment. Participants (BMI = 31.1 +/- 4.1 kg/m2; age = 38.4 +/- 6.7 y) were 144 women who attended a 12-month obesity treatment program and a comparison group (n = 49), who received a general health education program. The intervention included regular group meetings promoting lasting behavior changes in physical activity and dietary intake. Body image, quality of life, subjective well-being, and body weight were measured at baseline and treatment's end. Mediation was tested by multiple regression and a resampling approach to measure indirect effects. Treatment group assignment was the independent variable while changes in weight and in psychosocial variables were analyzed alternatively as mediators and as dependent variables. At 12 months, the intervention group had greater weight loss (-5.6 +/- 6.8% vs. -1.2 +/- 4.6%, p < .001) and larger decreases in body size dissatisfaction (effect size of 1.08 vs. .41, p < .001) than the comparison group. Significant improvements were observed in both groups for all other psychosocial variables (effect sizes ranging from .31-.75, p < .05). Mediation analysis showed that changes in body image and body weight were concurrently mediators and outcomes of treatment, suggesting reciprocal influences. Weight loss partially mediated the effect of treatment on quality of life and on self-esteem but the reciprocal effect was not observed. Changes in weight and body image may reciprocally affect each other during the course of behavioral obesity treatment. No evidence of reciprocal relationships was found for the other models under analysis; however, weight changes partially explained the effects of treatment on quality of life and self-esteem. Weight and psychosocial changes co-occur during treatment and will probably influence each other dynamically, in ways not yet adequately understood. Results from this study support the inclusion of intervention contents aimed at improving body image in weight management programs.

Over the past two decades, thousands of studies have demonstrated that Blacks receive lower quality medical care than Whites, independent of disease status, setting, insurance, and other clinically relevant factors. Despite this, there has been little progress towards eradicating these inequities. Almost a decade ago we proposed a conceptual model identifying mechanisms through which clinicians’ behavior, cognition, and decision making might be influenced by implicit racial biases and explicit racial stereotypes, and thereby contribute to racial inequities in care. Empirical evidence has supported many of these hypothesized mechanisms, demonstrating that White medical care clinicians: (1) hold negative implicit racial biases and explicit racial stereotypes, (2) have implicit racial biases that persist independently of and in contrast to their explicit (conscious) racial attitudes, and (3) can be influenced by racial bias in their clinical decision making and behavior during encounters with Black patients. This paper applies evidence from several disciplines to further specify our original model and elaborate on the ways racism can interact with cognitive biases to affect clinicians’ behavior and decisions and in turn, patient behavior and decisions. We then highlight avenues for intervention and make specific recommendations to medical care and grant-making organizations. PMID:24761152

Trust Me, I'm a Doctor: Examining Changes in How Privacy Concerns Affect Patient Withholding Behavior.

As electronic health records (EHRs) become ubiquitous in the health care industry, privacy breaches are increasing and being made public. These breaches may make consumers wary of the technology, undermining its potential to improve care coordination and research. Given the developing concerns around privacy of personal health information stored in digital format, it is important for providers to understand how views on privacy and security may be associated with patient disclosure of health information. This study aimed to understand how privacy concerns may be shifting patient behavior. Using a pooled cross-section of data from the 2011 and 2014 cycles of the Health Information and National Trends Survey (HINTS), we tested whether privacy and security concerns, as well as quality perceptions, are associated with the likelihood of withholding personal health information from a provider. A fully interacted multivariate model was used to compare associations between the 2 years, and interaction terms were used to evaluate trends in the factors that are associated with withholding behavior. No difference was found regarding the effect of privacy and security concerns on withholding behavior between 2011 and 2014. Similarly, whereas perceived high quality of care was found to reduce the likelihood of withholding information from a provider in both 2011 (odds ratio [OR] 0.73, 95% confidence interval [CI] 0.56-0.94) and 2014 (OR 0.61, 95% CI 0.48-0.76), no difference was observed between years. These findings suggest that consumers' beliefs about EHR privacy and security, the relationship between technology use and quality, and intentions to share information with their health care provider have not changed. These findings are counter to the ongoing discussions about the implications of security failures in other domains. Our results suggest that providers could ameliorate privacy and security by focusing on the care quality benefits EHRs provide. ©Daniel M Walker, Tyler Johnson, Eric W Ford, Timothy R Huerta.

Secondary science teachers' use of the affective domain in science education

NASA Astrophysics Data System (ADS)

Grauer, Bette L.

The purpose of this qualitative case study was to explore (a) the types of student affective responses that secondary science teachers reported emerged in science classes, (b) how those teachers worked with student affective responses, and (c) what interactions were present in the classroom when they worked with student affective responses. The study was motivated by research indicating that student interest and motivation for learning science is low. Eight secondary science teachers participated in the case study. The participants were selected from a pool of teachers who graduated from the same teacher education program at a large Midwest university. The primary sources of data were individual semi-structured interviews with the participants. Krathwohl's Taxonomy of the Affective Domain served as the research framework for the study. Student affective behavior reported by participants was classified within the five levels of Krathwohl's Affective Taxonomy: receiving, responding, valuing, organization, and characterization. Participants in the study reported student behavior representing all levels of the Affective Taxonomy. The types of behavior most frequently reported by participants were identified with the receiving and responding levels of the Affective Taxonomy. Organization behavior emerged during the study of perceived controversial science topics such as evolution. Participants in the study used student affective behavior to provide feedback on their lesson activities and instructional practices. Classroom interactions identified as collaboration and conversation contributed to the development of responding behavior. The researcher identified a process of affective progression in which teachers encouraged and developed student affective behavior changes from receiving to responding levels of the Affective Taxonomy.

Introduction: Despite many advances in the treatment of chronic renal failure, the quality of sleep in patients who suffer from this disease is at the risk. The high prevalence of sleep disorders in hemodialysis patients, which is concomitant with physical, behavioral, and psychological problems, has always affected these patients' quality of life (QOL). This study aimed to determine the relationship between quality of sleep and quality of life in hemodialysis patients. Methods: By using a descriptive and correlational design, this study was conducted on 245 hemodialysis patients in 2012. Patients were selected by convenience sampling from the hemodialysis ward of four training hospitals of Tabriz and Maragheh. Quality of sleep was measured by the Pittsburgh Sleep Quality Index (PSQI), and the quality of life for patients was measured by the Kidney Disease Quality Of Life questionnaire (KDQOL-SF). Results: 83.3% of hemodialysis patients had poor quality of sleep. Poor quality of life was significantly associated with poor quality of sleep. There was a significant negative correlation between global PSQI and important aspects of quality of life including physical health, symptoms and problems, the impact of kidney disease on daily life, burden of kidney disease, mental health, social support, and sexual function. Conclusion: The low quality of sleep in hemodialysis patients has an effect on the deterioration of their quality of life. Therefore, training, counseling, and advocacy programs should be developed to improve the patients' quality of sleep and quality of life, especially those with lower education level and income, and older people.

Radiotherapy is a common and effective treatment for women with breast cancer. However, radiotherapy has also been shown to adversely affect patients' emotional well-being. Currently, few mind-body interventions are designed to improve patients' quality of life during radiotherapy. One intervention which has demonstrated clinical efficacy in the breast cancer radiotherapy setting is Cognitive-Behavioral Therapy plus Hypnosis. The goal of this study was to investigate the impact of Cognitive-Behavioral Therapy plus Hypnosis on emotional distress in women with breast cancer undergoing radiotherapy. One hundred patients were randomly assigned to either the Cognitive-Behavioral Therapy plus Hypnosis (n = 50) or Attention Control (n = 50) group. Results revealed significant benefits of Cognitive-Behavioral Therapy plus Hypnosis on emotional distress at the mid-point (d = 0.54), the conclusion (d = 0.64), and 4 weeks following the conclusion (d = 0.65) of radiotherapy (all ps < 0.05). In summary, results support further study of Cognitive-Behavioral Therapy plus Hypnosis as an evidence-based intervention to reduce emotional distress in women with breast cancer. Cognitive-Behavioral Therapy plus Hypnosis has the benefits of being brief, noninvasive, lacking side-effects, and producing beneficial effects which last beyond the conclusion of radiotherapy. Given these strengths, we propose that Cognitive-Behavioral Therapy plus Hypnosis is a strong candidate for greater dissemination and implementation in cancer populations.

Emerging role of aripiprazole for treatment of irritability associated with autistic disorder in children and adolescents.

Autistic disorder is a largely misunderstood and difficult to treat neurodevelopmental disorder. Three core domains of functioning are affected by autistic disorder, ie, socialization, communication, and behavior. Signs of autistic disorder may be present early, but are frequently overlooked, resulting in a delay in its diagnosis and a subsequent delay in treatment. No one definitive therapy is available, and treatment consists of early educational and behavioral interventions, as well as drug therapy. Atypical antipsychotics have often been used in the treatment of autistic disorder to target irritability, aggression, and self-injurious behavior, all of which can interfere with other aspects of treatment. One atypical antipsychotic, aripiprazole, has recently been approved for treatment of irritability associated with autistic disorder. Based on the results from two randomized, controlled trials, with efficacy data from nearly 300 patients, treatment with aripiprazole was associated with reductions in irritability, global improvements in behavior, and improvements in quality of life from both the patient and caregiver perspectives. Dosage of aripiprazole ranged from 5 mg to 15 mg per day. Aripiprazole was well tolerated during clinical trials, with most adverse events considered mild or moderate. Clinically relevant weight gain occurred in about 30% of patients given aripiprazole, although when compared with other atypical antipsychotics, aripiprazole appears to have fewer metabolic effects and a lower risk of weight gain. However, pediatric patients taking any atypical antipsychotic should be carefully monitored for potential adverse events, because the long-term effects of antipsychotic therapy in this population are not well known. When used appropriately, aripiprazole has the potential to be an effective treatment for children with autistic disorder to improve irritability and aggressive behavior and improve quality of life.

Is "disease management" the answer to our problems? No! Population health management and (disease) prevention require "management of overall well-being".

Cramm, Jane Murray; Nieboer, Anna Petra

Disease management programs based on the chronic care model have achieved successful and long-term improvement in the quality of chronic care delivery and patients' health behaviors and physical quality of life. However, such programs have not been able to maintain or improve broader self-management abilities or social well-being, which decline over time in chronically ill patients. Disease management efforts, population health management initiatives and innovative primary care solutions are still mainly focused on clinical and functional outcomes and health behaviors (e.g., smoking cessation, exercise, and diet) failing to address individuals' overall quality of life and well-being. Individuals' ability to achieve well-being can be assessed with great specificity through the application of social production function (SPF) theory. This theory asserts that people produce their own well-being by trying to optimize the achievement of instrumental goals (stimulation, comfort, status, behavioral confirmation, affection) that provide the means to achieve the larger, universal goals of physical and social well-being. A shift in focus from the management of physical function, disease limitations, and lifestyle behaviors alone to an approach that fosters self-management abilities such as self-efficacy and resource investment as well as overall quality of life, is urgently needed. Disease management interventions should be aimed at adequately addressing all difficulties chronically ill patients face in life, such as the effects of pain and fatigue on the ability to maintain a job and social life and to participate in activities promoting physical and social well-being. Patients' ability to maintain engagement in stimulating work and social activities with the people who are important to them may be even more important than aspects of disease self-management such as blood pressure or glycemic control. Interventions should aim to make chronically ill patients capable of managing their own well-being and adequately addressing their needs in a broader sense. So, is disease management the answer to our problems in the time of aging populations and increased prevalence of unhealthy lifestyles, chronic illnesses, and comorbidity? No! Effective (disease) prevention, disease management, patient-centered care, and high-quality chronic care and/or population health management calls for management of overall well-being.

Potential Adverse Effects of Violent Video Gaming: Interpersonal- Affective Traits Are Rather Impaired Than Disinhibition in Young Adults

The increasing trend of mass shootings, which were associated with excessive use of violent video games, fueled the debate of possible effects violent video games may have on adolescents and young adults. The aim of this study was to investigate the possible link between violent video gaming effects and the disposition of adverse behavior traits such as interpersonal-affective deficits and disinhibition. Data of 167 young adults, collected by an online questionnaire battery, were analyzed for lifetime video game exposure differences (i.e., non-gamers, non-violent video gamers, stopped violent video game users, and ongoing violent video game users) as well as for recent exposure effects on adverse behavior traits (Levenson’s Psychopathy Scale), while controlling for other potentially confounding lifestyle factors. While interpersonal-affective deficits were significantly higher in participants with ongoing violent video game exposure compared to non-gamers and non-violent video gamers, disinhibition was significantly higher in both – stopped and ongoing – violent video game exposure groups compared to non-gamers. Recent violent video game exposure was a stronger predictor for interpersonal-affective deficits, but was also significant for disinhibition. Considering that we observed small to medium effects in a sample of young adults with little to moderate use of violent video games highlights the importance of further investigating the potential adverse effects of violent video games on quality of social relationships.

There is compelling evidence that the quality of maternal and paternal parenting behavior bears critical importance for child development. Yet, less is known of the degree of similarity between maternal and paternal parenting behavior in families, and especially little is known about the factors that may explain variation in degrees of similarity. This article aims to examine (a) the concordance (similarity) between the quality of mothers' and fathers' interactive behavior with their child and (b) the sociodemographic determinants of this concordance. The sample included 74 families (mother, father, and their child). The quality of maternal and paternal interactive behavior was assessed independently, and rated with the Maternal Behavior Q-Sort (mother-infant, 12 months; D. R. Pederson et al., 1990) or the Mutually Responsive Orientation scale (father-toddler, 18 months; N. Aksan et al., 2006). The results indicated that the overall correlation between the quality of mothers' and fathers' behavior was moderate. The concordance was greater among higher socioeconomic status families or when interacting with a boy, but did not differ according to the presence or absence of siblings in the family.

Mediators and moderators of behavior change in patients with chronic cardiopulmonary disease: the impact of positive affect and self-affirmation.

Among patients with chronic cardiopulmonary disease, increasing healthy behaviors improves outcomes, but such behavior changes are difficult for patients to make and sustain over time. This study aims to demonstrate how positive affect and self-affirmation improve health behaviors compared with a patient education control group. The patient education (PE control) patients completed a behavioral contract, promising to increase their physical activity or their medication adherence and received an educational guide. In addition to the contract and guide, the positive affect/self-affirmation intervention (PA intervention) patients also learned to use positive affect and self-affirmation to facilitate behavior change. Follow-up was identical. In 756 patients, enrolled in three randomized trials, the PA intervention resulted in increased positive affect and more success in behavior change than the PE control (p < .01). Behavior-specific self-efficacy also predicted success (p < .01). Induction of positive affect played a critical role in buffering against the adverse behavioral consequences of stress. Patients who experienced either negative psychosocial changes (p < .05) or interval negative life events (p < .05) fared better with the PA intervention than without it. The PA intervention increased self-efficacy and promoted success in behavior change by buffering stress.

Changing how I feel about the food: experimentally manipulated affective associations with fruits change fruit choice behaviors.

Fewer than half of Americans meet current recommendations for fruit and vegetable intake. The behavioral affective associations model posits that feelings and emotions associated with a behavior are a proximal influence on decision making. Cross-sectional evidence supports the model and suggests that affective associations predict fruit and vegetable consumption. The purpose of this study was to test whether a causal relation exists between affective associations about fruits and future fruit consumption behavior, as measured by a snack selection task. Following a baseline assessment of cognitive and affective variables, participants' (N = 161) affective associations about fruits were experimentally manipulated with an implicit priming paradigm. Images of fruits were repeatedly paired with positive, negative, or neutral affective stimuli. The key outcome measure was a behavioral choice task in which participants chose between fruit and a granola bar. Participants in the positive prime condition were three times more likely than those in the negative condition to select a piece of fruit over the granola bar alternative in the snack selection task. They were also twice as likely as those in the neutral condition to select fruit. There were no changes in self-reported affective associations or cognitive beliefs. These findings provide further evidence of the implicit and direct influence of affective associations on behavior, suggesting the need to both incorporate the role of affect in health decision making models, as well as the potential utility of intervention strategies targeting affective associations with health-related behaviors.

Using the Transtheoretical Model of behavioral change, this study evaluates the relationship between sleep quality and the motivation and maintenance processes of healthy behavior change. The current study is an analysis of data collected in 2008 from an online health risk assessment (HRA) survey completed by participants of the Kansas State employee wellness program (N=13,322). Using multinomial logistic regression, associations between self-reported sleep quality and stages of change (i.e. precontemplation, contemplation, preparation, action, maintenance) in five health behaviors (stress management, weight management, physical activities, alcohol use, and smoking) were analyzed. Adjusted for covariates, poor sleep quality was associated with an increased likelihood of contemplation, preparation, and in some cases action stage when engaging in the health behavior change process, but generally a lower likelihood of maintenance of the healthy behavior. The present study demonstrated that poor sleep quality was associated with an elevated likelihood of contemplating or initiating behavior change, but a decreased likelihood of maintaining healthy behavior change. It is important to include sleep improvement as one of the lifestyle management interventions offered in EWP to comprehensively reduce health risks and promote the health of a large employee population.

Although the commercial availability and implementation of virtual reality interfaces has seen rapid growth in recent years, little research has been conducted on the potential for virtual reality to affect consumer behavior. One unaddressed issue is how our real world attitudes are affected when we have a virtual experience with the target of those attitudes. This study compared participant (N=60) attitudes toward car brands before and after a virtual test drive of those cars was provided. Results indicated that attitudes toward test brands changed after experience with virtual representations of those brands. Furthermore, manipulation of the quality of this experience (in this case modification of driving difficulty) was reflected in the direction of attitude change. We discuss these results in the context of the associative-propositional evaluation model.

Honey Bee (Apis mellifera) Queen Reproductive Potential Affects Queen Mandibular Gland Pheromone Composition and Worker Retinue Response

2016-01-01

Reproductive division of labor is one of the defining traits of honey bees (Apis mellifera), with non-reproductive tasks being performed by workers while a single queen normally monopolizes reproduction. The decentralized organization of a honey bee colony is maintained in large part by a bouquet of queen-produced pheromones, the distribution of which is facilitated by contact among workers throughout the hive. Previous studies have shown that the developmental fate of honey bee queens is highly plastic, with queens raised from younger worker larvae exhibiting higher measures of reproductive potential compared to queens raised from older worker larvae. We investigated differences in the chemical composition of the mandibular glands and attractiveness to workers of “high-quality” queens (i.e., raised from first instar worker larvae; more queen-like) and “low-quality” queens (i.e., raised from third instar worker larvae; more worker-like). We characterized the chemical profiles of the mandibular glands of high-quality queens and low-quality queens using GC-MS and used the worker retinue response as a measure of the attractiveness to workers of high-quality queens vs. low-quality queens. We found that queen quality affected the chemical profiles of mandibular gland contents differently across years, showing significant differences in the production of the queen mandibular pheromone (“QMP”) components HVA and 9-HDA in 2010, but no significant differences of any glandular compound in 2012. We also found that workers were significantly more attracted to high-quality queens than to low-quality queens in 2012, possibly because of increased attractiveness of their mandibular gland chemical profiles. Our results indicate that the age at which honey bee larvae enter the “queen-specific” developmental pathway influences the chemical composition of queen mandibular glands and worker behavior. However, these changes are not consistent across years, suggesting that other external factors may play important roles in modulating queen quality. PMID:27281328

Taste Perception of Sweet, Sour, Salty, Bitter, and Umami and Changes Due to l-Arginine Supplementation, as a Function of Genetic Ability to Taste 6-n-Propylthiouracil.

Behavioral reaction to different taste qualities affects nutritional status and health. 6- n -Propylthiouracil (PROP) tasting has been reported to be a marker of variation in taste perception, food preferences, and eating behavior, but results have been inconsistent. We showed that l-Arg can enhance the bitterness intensity of PROP, whilst others have demonstrated a suppression of the bitterness of quinine. Here, we analyze the taste perception of sweet, sour, salty, bitter, and umami and the modifications caused by l-Arg supplementation, as a function of PROP-taster status. Taste perception was assessed by testing the ability to recognize, and the responsiveness to, representative solutions of the five primary taste qualities, also when supplemented with l-Arg, in subjects classified as PROP-tasting. Super-tasters, who showed high papilla density, gave higher ratings to sucrose, citric acid, caffeine, and monosodium l-glutamate than non-tasters. l-Arg supplementation mainly modified sucrose perception, enhanced the umami taste, increased NaCl saltiness and caffeine bitterness only in tasters, and decreased citric acid sourness. Our findings confirm the role of PROP phenotype in the taste perception of sweet, sour, and bitter and show its role in umami. The results suggest that l-Arg could be used as a strategic tool to specifically modify taste responses related to eating behaviors.

We examined how individual differences in mood and anxiety in the early postpartum period are related to brain response to infant stimuli during fMRI, with particular focus on regions implicated in both maternal behavior and mood/anxiety, that is, the subgenual anterior cingulate cortex (sgACC) and the amygdala. At approximately 3 months postpartum, 22 mothers completed an affect-rating task (ART) during fMRI, where their affective response to infant stimuli was explicitly probed. Mothers viewed/rated four infant face conditions: own positive (OP), own negative (ON), unfamiliar positive (UP), and unfamiliar negative (UN). Mood and anxiety were measured by the Edinburgh Postnatal Depression Scale (EDPS) and the State-Trait Anxiety Inventory-Trait Version (STAI-T); maternal factors related to parental stress and attachment were also assessed. Brain-imaging data underwent a random-effects analysis, and cluster-based statistical thresholding was applied to the following contrasts: OP-UP, ON-UN, OP-ON, and UP-UN. Our main finding was that poorer quality of maternal experience was significantly related to reduced amygdala response to OP compared to UP infant faces. Our results suggest that, in human mothers, infant-related amygdala function may be an important factor in maternal anxiety/mood, in quality of mothering, and in individual differences in the motivation to mother. We are very grateful to the staff at the Imaging Research Center of the Brain-Body Institute for their contributions to this project.

2010-03-01

Intervertebral spacers are made of different materials, which can affect the postfusion magnetic resonance imaging (MRI) scans. Susceptibility artifacts, especially for metallic implants, can decrease the image quality. This study aimed to determine whether magnesium as a lightweight and biocompatible metal is suitable as a biomaterial for spinal implants based on its MRI artifacting behavior. To compare artifacting behaviors, we implanted into one porcine cadaveric spine different test spacers made of magnesium, titanium, and CFRP. All test spacers were scanned using two T1-TSE MRI sequences. The artifact dimensions were traced on all scans and statistically analyzed. The total artifact volume and median artifact area of the titanium spacers were statistically significantly larger than magnesium spacers (P < 0.001), while magnesium and CFRP spacers produced almost identical artifacting behaviors (P > 0.05). Our results suggest that spinal implants made with magnesium alloys will behave more like CFRP devices in MRI scans.

The purpose of the study was to investigate seasonal variation in mood and behavior among a group of office workers in Sweden (56°N). Thirty subjects participated in this longitudinal study. The subjects kept a weekly log that included questionnaires for ratings of psychological wellbeing and daily sleep-activity diaries where they also noted time spent outdoors. The lighting conditions in the offices were subjectively evaluated during one day, five times over the year. There was a seasonal variation in positive affect and in sleep-activity behavior. Across the year, there was a large variation in the total time spent outdoors in daylight. The subjects reported seasonal variation concerning the pleasantness, variation and strength of the light in the offices and regarding the visibility in the rooms. Finally, the subjects spent most of their time indoors, relying on artificial lighting, which demonstrates the importance of the lighting quality in indoor environments.

Relationship between spatter formation and dynamic molten pool during high-power deep-penetration laser welding

The spatter and the molten pool behavior, which were the important phenomena concerned with the welding quality, were observed and studied by using the high-speed camera and the X-ray transmission imaging system during laser welding under different welding parameters. The formation mechanism of spatter and the corresponding relationships between the spatter and molten pool behavior were investigated. The increase of laser power could cause more intense evaporation and lead to more spatter. When the focal position of laser beam was changed, different forms of spatter were generated, as well as the flow trends of molten metal on the front keyhole wall and at the rear molten pool were changed. The results revealed that the behavior of molten pool, which could be affected by the absorbed energy distribution in the keyhole, was the key factor to determine the spatter formation during laser welding. The relatively sound weld seam could be obtained during laser welding with the focal position located inside the metal.

A significant proportion of persons affected by Parkinson's disease (PD) are over age 65 years. Mental health issues are often less a focus of treatment in this population than physical manifestations of the illness. Anxiety or depression alone, as well as comorbid depression and anxiety, are underrecognized in patients with PD and are associated with deleterious effects on physical and interpersonal functioning, negatively impacting quality of life and well-being. We offer a brief overview of salient clinical points with respect to assessment and treatment approaches to enhance efficacy of the treatment of mental health symptoms in older adults with PD. Cognitive behavior therapy involves the patient learning to overcome behavioral avoidance associated with anxiety and challenge unhelpful negative cognitions. It is suggested that cognitive behavior therapy is an effective approach to treatment of anxiety and depression in PD and should be offered as a treatment to patients. © 2013 Movement Disorder Society.

Ending disruptive behavior: staff nurse recommendations to nurse educators.

The purpose of this qualitative descriptive study was to identify educational strategies that can prepare new graduates to manage disruptive behavior (DB) in the workplace. DB is any inappropriate behavior, confrontation, or conflict - ranging from verbal abuse to sexual harassment - that harms or intimidates others to the extent that quality of care or patient safety could be compromised. Individual interviews were conducted with nine staff nurses currently in practice in acute care settings in the United States. Staff nurses recommended educational strategies that focused on communication skills for professional practice. These included learning how to communicate with hostile individuals, and giving and receiving constructive criticism. Descriptions that participants provided about their work culture were an unexpected finding that has relevance for nurse educators as they prepare students for transition to practice Nurses described lack of management support and intervention for DB situations, personality clashes with coworkers, and devaluation of nursing work as affecting professional practice.

The spatial scale at which organisms respond to human activity can affect both ecological function and conservation planning. Yet little is known regarding the spatial scale at which distinct behaviors related to reproduction and survival are impacted by human interference. Here we provide a novel approach to estimating the spatial scale at which a top predator, the puma (Puma concolor), responds to human development when it is moving, feeding, communicating, and denning. We find that reproductive behaviors (communication and denning) require at least a 4× larger buffer from human development than non-reproductive behaviors (movement and feeding). In addition, pumas give a wider berth to types of human development that provide a more consistent source of human interference (neighborhoods) than they do to those in which human presence is more intermittent (arterial roads with speeds >35 mph). Neighborhoods were a deterrent to pumas regardless of behavior, while arterial roads only deterred pumas when they were communicating and denning. Female pumas were less deterred by human development than males, but they showed larger variation in their responses overall. Our behaviorally explicit approach to modeling animal response to human activity can be used as a novel tool to assess habitat quality, identify wildlife corridors, and mitigate human-wildlife conflict.

PedsQL relates to function and behavior in very low and normal birth weight 2- and 3-year-olds from a regional cohort.

To compare PedsQL scores in young children who were very low (< or =1,500 g) or normal birth weight (>2,500 g) and to examine the relationship of the PedsQL score to behavioral and functional scores. The PedsQL, Achenbach Child Behavior Checklist and the PEDI functional scales were telephone administered to parents of a regional cohort of 672 very low birth weight and 455 normal birth weight children, 2- and 3-years old. PedsQL scales were regressed on behavior, function and health conditions. Mean (SD) overall PedsQL score was 91 (8.4) for normal birth weight and 87 (12) for very low birth weight children, and changed little when standardized to the race/ethnicity and maternal education of corresponding Wisconsin births. Mobility function and the CBCL explained 58% of the variance in PedsQL, but the relationship was curvilinear. The PedsQL is sensitive to health problems of very low birth weight in young children. The PedsQL is quite strongly related to mobility and behavior problems, but scales these differently than do standard instruments. Parents either do not think of subtle issues with child function and behavior without specific prompting or do not perceive them as problems affecting quality of life.

Effects of nutritional deprivation on development and behavior in the subsocial bee Ceratina calcarata (Hymenoptera: Xylocopinae).

By manipulating resources or dispersal opportunities, mothers can force offspring to remain at the nest to help raise siblings, creating a division of labor. In the subsocial bee Ceratina calcarata , mothers manipulate the quantity and quality of pollen provided to the first female offspring, producing a dwarf eldest daughter that is physically smaller and behaviorally subordinate. This daughter forages for her siblings and forgoes her own reproduction. To understand how the mother's manipulation of pollen affects the physiology and behavior of her offspring, we manipulated the amount of pollen provided to offspring and measured the effects of pollen quantity on offspring development, adult body size and behavior. We found that by experimentally manipulating pollen quantities we could recreate the dwarf eldest daughter phenotype, demonstrating how nutrient deficiency alone can lead to the development of a worker-like daughter. Specifically, by reducing the pollen and nutrition to offspring, we significantly reduced adult body size and lipid stores, creating significantly less aggressive, subordinate individuals. Worker behavior in an otherwise solitary bee begins to explain how maternal manipulation of resources could lead to the development of social organization and reproductive hierarchies, a major step in the transition to highly social behaviors. © 2017.

Because cognitive processes decline in the earliest stages of Alzheimer's disease (AD), the driving abilities are often affected. The naturalistic driving approach is relevant to study the driving habits and behaviors in normal or critical situations in a familiar environment of participants. This pilot study analyzed in-car video recordings of naturalistic driving in patients with early-stage AD and in healthy controls, with a special focus on tactical self-regulation behavior. Twenty patients with early-stage AD (Diagnosis and Statistical Manual of Mental Disorders, Fourth Edition [DSM-IV] criteria), and 21 healthy older adults were included in the study. Data collection equipment was installed in their personal vehicles. Two expert psychologists assessed driving performance using a specially designed Naturalistic Driving Assessment Scale (NaDAS), paying particular attention to tactical self-regulation behavior, and they recorded all critical safety events. Poorer driving performance was observed among AD drivers: their tactical self-regulation behavior was of lower quality. AD patients had also twice as many critical events as healthy drivers and three times more "unaware" critical events. This pilot study using a naturalistic approach to accurately show that AD drivers have poorer tactical self-regulation behavior than healthy older drivers. Future deployment of assistance systems in vehicles should specifically target tactical self-regulation components.

THE QUALITY OF FATHER-CHILD ROUGH-AND-TUMBLE PLAY AND TODDLERS' AGGRESSIVE BEHAVIOR IN CHINA.

The purpose of this study was to explore the influence of the quality of early father-child rough-and-tumble play (RTP) on toddler aggressive behaviors and more fully understand how child, mother, and father characteristics were associated with higher quality father-child RTP among contemporary urban Chinese families. Participants included 42 families in Changsha, China. Play observations of fathers and their children were coded for RTP quality. The specific RTP quality of father-child reciprocity of dominance was associated with fewer toddler aggressive behaviors, as rated by both fathers and mothers. Mothers' democratic parenting attitudes were associated with higher quality father-child RTP. These findings suggest that higher quality father-child RTP may be one way in which some fathers influence children's expression of aggressive behaviors, and the quality of father-child RTP may be influenced by the broader family, social, and cultural contexts. © 2017 Michigan Association for Infant Mental Health.

Pregnant and parenting adolescents and their younger sisters: the influence of relationship qualities for younger sister outcomes.

PubMed

East, P L; Shi, C R

1997-04-01

On the basis of social modeling theory and a sibling interaction hypothesis, it was hypothesized that specific relationship qualities between a pregnant or parenting teen and her younger sister would be associated with permissive younger sister outcomes, such as permissive childbearing attitudes and permissive sexual behavior. Results indicated that negative relationship qualities, such as rivalry, competition, and conflict, were more closely related to younger sisters engaging in problem delinquent-like behavior and sexual behavior than were positive relationship qualities, such as warmth and closeness. Additionally, a shared friendship network with the older sister was found to be associated with extensive younger sister problem behavior and sexual behavior. Three potential explanatory processes are discussed.

Female remating in target pest species can affect the efficacy of control methods such as the Sterile Insect Technique (SIT) but very little is known about the postcopulatory mating behavior of these pests. In this study, we investigated the remating behavior of female Anastrepha serpentina (Diptera: Tephritidae), an oligophagous pest of Sapotaceae. First, we tested how long the sexual refractory period of females lasted after an initial mating. Second, we tested the effect of male and female sterility, female ovipositing opportunities and male density on female propensity to remate. Lastly, we tested if the amount of sperm stored by females was correlated to the likelihood of females to remate. We found that receptivity of mass-reared A. serpentina females had a bimodal response, with up to 16% of mass-reared A. serpentina females remating five days after the initial copulation, decreasing to 2% at 10 and 15 days and increasing to 13% after 20 days. Compared to fertile males, sterile males were less likely to mate and less likely to inhibit females from remating. Copula duration of sterile males was shorter compared to fertile males. Remating females were less likely to mate with a sterile male as a second mate. Sterile females were less likely to mate or remate compared to fertile females. Opportunity to oviposit and male density had no effect on female remating probability. Sperm numbers were not correlated with female likelihood to remate. Information on the post-copulatory behavior of mass-reared A. serpentina will aid fruit fly managers in improving the quality of sterile males. We discuss our results in terms of the differences this species presents in female remating behavior compared to other tephritids. Copyright © 2015 Elsevier Ltd. All rights reserved.

Empathy in Medical Students Is Moderated by Openness to Spirituality.

Empathy is one component of medical student education that may be important to nurture, but there are many potential psychological barriers to empathy, such as student depression, burnout, and low quality of life or wellness behaviors. However, few studies have addressed how positive behaviors such as wellness and spirituality, in combination with these barriers, might affect empathy. We hypothesized a negative relationship between psychological distress and empathy, and a positive relationship between empathy and wellness behaviors. We also hypothesized that openness to others' spirituality would moderate the effects of psychological distress on empathy in medical students. This cross-sectional study included 106 medical students in a public medical school in the U.S. Midwest. Mailed questionnaires collected student information on specialty choice and sociodemographics, empathy, spirituality openness, religiosity, wellness, burnout, depression, anxiety, and stress. Hierarchical multiple regression analysis was conducted, with empathy as the dependent variable, psychological distress and all wellness behaviors as predictors, and spirituality openness as a moderator. Specialty choice, burnout, wellness behaviors, spirituality openness, and religiosity were significant independent predictors of empathy. In addition, when added singly, one interaction was significant: Spirituality Openness × Depression. Spirituality openness was related to empathy only in nondepressed students. Empathy of students with higher levels of depression was generally lower and not affected by spirituality openness. Nondepressed students who reported lower openness to spirituality might benefit most from empathy training, because these students reported the lowest empathy. Highly depressed or disengaged students may require interventions before empathy can be addressed. In addition, burnout was related to lower levels of empathy and wellness was related to higher levels. These provide potential points of intervention for medical schools developing tools to increase medical trainees' empathy levels.

To quality assess a sample of health behavior change apps from the NHS Apps Library using a rating tool based on the 2014 National Institute for Health and Care Excellence behavior change guidance (NICE BCG). A qualitative analysis of the NICE BCG identified themes and questions for a quality assessment of health behavior change apps. These were refined by further discussion and piloting, and applied by two independent raters to a sample of NHS Library apps (N=49). Disagreements were resolved following discussions with a third rater. Themes identified were; purpose, planning, usability, tailoring, behavior change technique (BCT), maintenance, evaluation, data security and documentation. Overall, purpose of the apps was clear, but evidence for collaboration with users or professionals was lacking. Usability information was poor and tailoring disappointing. Most used recognized BCTs but paid less attention to behavior maintenance than initiation. Information on app evaluation and documentation was sparse. This study furthers the work of the NHS Apps Library, adapting the NICE (2014) behavior change guidance for quality assessment of behavior change apps. This study helps lay the foundations for development of a quality assurance tool for mobile health apps aimed at health behavior change. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Assessing physician/patient relationships in the presence of HIV/AIDS: an exploratory study.

PubMed

Taylor, S A; Madrigal, C

1998-01-01

The following study investigates the nature of the relationship between physicians and HIV/AIDS patients within the context of the rapidly evolving services/relationship marketing literatures. The emerging evidence suggests that service providers generally play a critical role in the development of positive consumer attitudes and behaviors, and that relationship marketing practices can contribute to the delivery of health services. However, to date, there appears little evidence supporting the efficacy of employing relationship marketing practices in relation to a target market of HIV/AIDS patients. This exploratory study contributes to the body of knowledge by more closely investigating the nature of the patient-physician relationship relative to HIV/AIDS patients' attitudes, marketing-related behaviors, and overall quality-of-life/life satisfaction judgments. The results of this study first suggest that HIV/AIDS patients use the expectancy disconfirmation model when evaluating the performance of their physician. A reliance on expectancy disconfirmation suggests the likely prevalent role of service quality perceptions and satisfaction judgments in evaluating their relationship with their physician. Second, the results appear to support the conclusion that the patient's evaluation of their physician relationship and subsequent behaviors (e.g., word-of-mouth) are directly related to the patient's general perception of received health services. Thus, the patient/physician relationship may play a particularly powerful role in determining patient (marketing related) outcomes relative to other health service settings. Third, a direct influence is supported between negative affective reactions by patients and subsequent outcome behaviors. This finding lends support for the potential efficacy of service recovery efforts when rendering treatment to HIV/AIDS patients. Finally, evidence is presented demonstrating the effect of positive perceptions of the patient/provider relationship on these patients' overall evaluation of their quality-of-life/life satisfaction. The managerial and research implications of this study are presented and discussed.

Factors Associated with Colorectal Cancer Screening among Younger African American Men: A Systematic Review.

2015-01-01

Of cancers affecting both men and women, colorectal cancer (CRC) is the second leading cancer killer among African Americans in the U.S. Compared to White men, African American men have incidence and mortality rates 25% and 50% higher from CRC. Despite the benefits of early detection and the availability of effective screening, most adults over age 50 have not undergone testing, and disparities in colorectal cancer screening (CRCS) persist. Owing to CRC's high incidence and younger age at presentation among African American men, CRCS is warranted at age 45 rather than 50. However, the factors influencing young adult (i.e., age < 50) African American men's intention to screen and/or their CRCS behaviors has not been systematically assessed. To assess whether the factors influencing young adult African American men's screening intentions and behaviors are changeable through structured health education interventions, we conducted a systematic review, with the two-fold purpose of: (1) synthesizing studies examining African American men's knowledge, beliefs, and behaviors regarding CRCS; and (2) assessing these studies' methodological quality. Utilizing Garrard's Matrix Method, a total of 28 manuscripts met our inclusion/exclusion criteria: 20 studies followed a non-experimental research design, 4 comprised a quasi-experimental design, and 4, an experimental design. Studies were published between 2002 and 2012; the majority, between 2007 and 2011. The factors most frequently assessed were behaviors (79%), beliefs (68%), and knowledge (61%) of CRC and CRCS. Six factors associated with CRC and CRCS emerged: previous CRCS, CRC test preference, perceived benefits, perceived barriers, CRC/CRCS knowledge, and physician support/recommendation. Studies were assigned a methodological quality score (MQS - ranging from 0 to 21). The mean MQS of 10.9 indicated these studies were, overall, of medium quality and suffered from specific flaws. Alongside a call for more rigorous research, this review provides important suggestions for practice and culturally relevant interventions.

Parents who are child welfare services-involved (CWSI) often have a history of childhood adversity and depressive symptoms. Both affect parenting quality, which in turn influences child adaptive functioning. We tested a model of the relations between parental depression and child regulatory outcomes first proposed by Lyons-Ruth and colleagues (2002). We hypothesized that both parental depression and parenting quality mediate the effects of parental early adversity on offspring regulatory outcomes. Participants were 123 CWSI parents and their toddlers who were assessed three times over a period of six months. At T1, parents reported on their childhood adversity and current depressive symptoms. At T2, parents’ sensitivity to their child’s distress and non-distress cues were rated from a videotaped teaching task. At T3, observers rated children’s emotional regulation, orientation/engagement, and secure base behavior. The results of a path model partly supported hypotheses. Parent childhood adversity was associated with current depressive symptoms, which in turn was related to parent sensitivity to child distress but not non-distress. Sensitivity to distress also predicted secure base behavior. Depression directly predicted orientation/engagement, also predicted by sensitivity to non-distress. Sensitivity to distress predicted emotion regulation and orientation/engagement. Results are discussed in terms of intervention approaches for CWSI families. PMID:29266280

Previous experience affects how young primates respond to challenging social situations. The present retrospective study looked at one aspect of early experience, the quality of the mother-infant relationship, to determine its relationship to young bonnet and pigtail macaques' responses to two social challenges: temporary maternal separation at 5-6 months and permanent transfer to an unfamiliar peer group at 16-17 months. Relationship quality was measured quantitatively on 30 macaque mother-infant pairs with the Relationship Quality Index (RQI), the ratio of relative affiliation to relative agonism as previously applied to capuchin monkeys. Infants with high RQI values had amicable mother-infant relationships and infants with low RQI values had agonistic mother-infant relationships. Young monkeys with amicable and agonistic relationships showed consistent differences in behavior before, during, and after each social challenge, supporting the hypothesis that juveniles from amicable mother-infant relationships based on the RQI coped more effectively with social challenges than did juveniles from agonistic mother-infant relationships. Results suggest 1) characteristic amicability or agonism in early mother-offspring macaque relationships has the potential to influence offspring behavior in tense social contexts and 2) the RQI is useful as one of a coordinated suite of methods for studying the development of social skills.

Bipolar disorder (BD) affects the social functioning and quality of life (QoL) of its patients. This study aimed to investigate whether there is an association between social support (SS), and suicidal behavior in BD I patients compared to healthy controls; secondarily, we evaluated the influence of QoL on those variables. A total of 119 euthymic outpatients with BD I, 46 of whom had attempted suicide (SAs) and 73 who had not (non-SAs), were compared to 63 healthy controls, through the Medical Outcomes Study Social Support Scale and World Health Organization's Quality of Life Instrument. No differences were noted in SS and QoL between SAs and non-SAs. Compared to healthy controls, non-SAs showed lower values in the positive social interaction domain of SS, and the patients, as a whole, showed lower values in affectionate and positive social interaction domains of SS. Compared to healthy controls, SAs had lower values in the environmental domain of QoL, and the patients, as a whole, had lower values in the environmental, social, and psychological domains of QoL. There was positive correlation between SS and QoL. Although BD is a disabling disease, patients receive inadequate SS. Interventions that may alter the SS in these patients should be investigated.

A conceptual framework for effectively anticipating water-quality changes resulting from changes in agricultural activities

USGS Publications Warehouse

Capel, Paul D.; Wolock, David M.; Coupe, Richard H.; Roth, Jason L.

2018-01-10

Agricultural activities can affect water quality and the health of aquatic ecosystems; many water-quality issues originate with the movement of water, agricultural chemicals, and eroded soil from agricultural areas to streams and groundwater. Most agricultural activities are designed to sustain or increase crop production, while some are designed to protect soil and water resources. Numerous soil- and water-protection practices are designed to reduce the volume and velocity of runoff and increase infiltration. This report presents a conceptual framework that combines generalized concepts on the movement of water, the environmental behavior of chemicals and eroded soil, and the designed functions of various agricultural activities, as they relate to hydrology, to create attainable expectations for the protection of—with the goal of improving—water quality through changes in an agricultural activity.The framework presented uses two types of decision trees to guide decision making toward attainable expectations regarding the effectiveness of changing agricultural activities to protect and improve water quality in streams. One decision tree organizes decision making by considering the hydrologic setting and chemical behaviors, largely at the field scale. This decision tree can help determine which agricultural activities could effectively protect and improve water quality in a stream from the movement of chemicals, or sediment, from a field. The second decision tree is a chemical fate accounting tree. This decision tree helps set attainable expectations for the permanent removal of sediment, elements, and organic chemicals—such as herbicides and insecticides—through trapping or conservation tillage practices. Collectively, this conceptual framework consolidates diverse hydrologic settings, chemicals, and agricultural activities into a single, broad context that can be used to set attainable expectations for agricultural activities. This framework also enables better decision making for future agricultural activities as a means to reduce current, and prevent new, water-quality issues.

Optimization and Characterization of the Friction Stir Welded Sheets of AA 5754-H111: Monitoring of the Quality of Joints with Thermographic Techniques

2017-01-01

Friction Stir Welding (FSW) is a solid-state welding process, based on frictional and stirring phenomena, that offers many advantages with respect to the traditional welding methods. However, several parameters can affect the quality of the produced joints. In this work, an experimental approach has been used for studying and optimizing the FSW process, applied on 5754-H111 aluminum plates. In particular, the thermal behavior of the material during the process has been investigated and two thermal indexes, the maximum temperature and the heating rate of the material, correlated to the frictional power input, were investigated for different process parameters (the travel and rotation tool speeds) configurations. Moreover, other techniques (micrographs, macrographs and destructive tensile tests) were carried out for supporting in a quantitative way the analysis of the quality of welded joints. The potential of thermographic technique has been demonstrated both for monitoring the FSW process and for predicting the quality of joints in terms of tensile strength. PMID:29019948

Biofield therapies: helpful or full of hype? A best evidence synthesis.

Jain, Shamini; Mills, Paul J

2010-03-01

Biofield therapies (such as Reiki, therapeutic touch, and healing touch) are complementary medicine modalities that remain controversial and are utilized by a significant number of patients, with little information regarding their efficacy. This systematic review examines 66 clinical studies with a variety of biofield therapies in different patient populations. We conducted a quality assessment as well as a best evidence synthesis approach to examine evidence for biofield therapies in relevant outcomes for different clinical populations. Studies overall are of medium quality, and generally meet minimum standards for validity of inferences. Biofield therapies show strong evidence for reducing pain intensity in pain populations, and moderate evidence for reducing pain intensity hospitalized and cancer populations. There is moderate evidence for decreasing negative behavioral symptoms in dementia and moderate evidence for decreasing anxiety for hospitalized populations. There is equivocal evidence for biofield therapies' effects on fatigue and quality of life for cancer patients, as well as for comprehensive pain outcomes and affect in pain patients, and for decreasing anxiety in cardiovascular patients. There is a need for further high-quality studies in this area. Implications and future research directions are discussed.

What can wearable sensors and usage of smart phones tell us about academic performance, self-reported sleep quality, stress and mental health condition? To answer this question, we collected extensive subjective and objective data using mobile phones, surveys, and wearable sensors worn day and night from 66 participants, for 30 days each, totaling 1,980 days of data. We analyzed daily and monthly behavioral and physiological patterns and identified factors that affect academic performance (GPA), Pittsburg Sleep Quality Index (PSQI) score, perceived stress scale (PSS), and mental health composite score (MCS) from SF-12, using these month-long data. We also examined how accurately the collected data classified the participants into groups of high/low GPA, good/poor sleep quality, high/low self-reported stress, high/low MCS using feature selection and machine learning techniques. We found associations among PSQI, PSS, MCS, and GPA and personality types. Classification accuracies using the objective data from wearable sensors and mobile phones ranged from 67–92%.

This study used cross-sectional data from the International Study of Childhood Obesity, Lifestyle and the Environment. Children (9-11 years) were recruited from sites in 12 nations (n = 5759). Clustering input variables were 24-hour accelerometry and self-reported diet and screen time. Health-related quality of life was self-reported with KIDSCREEN-10. Cluster analyses (using compositional analysis techniques) were performed on a site-wise basis. Lifestyle behavior cluster characteristics were compared between sites. The relationship between cluster membership and health-related quality of life was assessed with the use of linear models. Lifestyle behavior clusters were similar across the 12 sites, with clusters commonly characterized by (1) high physical activity (actives); (2) high sedentary behavior (sitters); (3) high screen time/unhealthy eating pattern (junk-food screenies); and (4) low screen time/healthy eating pattern and moderate physical activity/sedentary behavior (all-rounders). Health-related quality of life was greatest in the all-rounders cluster. Children from different world regions clustered into groups of similar lifestyle behaviors. Cluster membership was related to differing health-related quality of life, with children from the all-rounders cluster consistently reporting greatest health-related quality of life at sites around the world. Findings support the importance of a healthy combination of lifestyle behaviors in childhood: low screen time, healthy eating pattern, and balanced daily activity behaviors (physical activity and sedentary behavior).

This study investigated the mediating role of institutional trust and affective commitment on the relationship between organizational justice and organizational citizenship behaviors. The study participants were 315 faculty members at 67 public/private universities of technology and vocational colleges in Taiwan. Structural equation modeling was used to analyze the relationships between the variables and assess the goodness of fit of the overall model. Organizational justice was positively related to institutional trust and there was an indirect effect of organizational justice on affective commitment through institutional trust. In addition, the relation between institutional trust and affective commitment was positive and affective commitment was shown to have a positive relation to organizational citizenship behaviors. Institutional trust was found to indirectly affect organizational citizenship behaviors through affective commitment. Most importantly, this study suggested a mediating effect of institutional trust and affective commitment on the relation between organizational justice and organizational citizenship behaviors. Implications, limitations, and future research were also discussed.

Abdominal aortic aneurysm (AAA) is known as a leading cause of death in the United States. AAA is an abnormal dilation of the aorta, which usually occurs below the renal arteries and causes an expansion at least 1.5 times its normal diameter. It has been shown that biomechanical parameters of the aortic tissue coupled with a set of specific geometric parameters characterizing the vessel expansion, affect the risk of aneurysm rupture. Here, we developed a numerical framework that incorporates both biomechanical and geometrical factors to study the behavior of abdominal aortic aneurysm. Our workflow enables the extraction of the aneurysm geometry from both clinical quality, as well as low-resolution MR images. We used a two-parameter, hyper-elastic, isotropic, incompressible material to model the vessel tissue. Our numerical model was tested using both synthetic and mouse data and we evaluated the effects of the geometrical and biomechanical properties on the developed peak wall stress. In addition, we performed several parameter sensitivity studies to investigate the effect of different factors affecting the AAA and its behavior and rupture. Lastly, relationships between different geometrical and biomechanical parameters and peak wall stress were determined. These studies help us better understand vessel tissue response to various loading, geometry and biomechanics conditions, and we plan to further correlate these findings with the pathophysiological conditions from a patient population diagnosed with abdominal aortic aneurysms.

The effects of global stressors on a species may be mediated by the stressors' impact on coexisting taxa. For instance, herbivore-algae interactions may change due to alterations in algal nutritional quality resulting from high CO2 levels associated with ocean acidification (OA). We approached this issue by assessing the indirect effects of OA on the trophic interactions between the amphipod Orchestoidea tuberculata and the brown alga Durvillaea antarctica, two prominent species of the South-east Pacific coast. We predicted that amphipod feeding behavior and performance (growth rate) will be affected by changes in the palatability of the algae exposed to high levels (1000 ppm) of CO2. We exposed algae to current and predicted (OA) atmospheric CO2 levels and then measured their nutritive quality and amphipod preference in choice trials. We also assessed consumption rates separately in no-choice trials, and measured amphipod absorption efficiency and growth rates. Protein and organic contents of the algae decreased in acidified conditions and amphipods showed low preference for these algae. However, in the no-choice trials we recorded higher grazing rates on algae exposed to OA. Although amphipod absorption efficiency was lower on these algae, growth rates did not differ between treatments, which suggests the occurrence of compensatory feeding. Our results suggest that changes in algal nutritional value in response to OA induce changes in algal palatability and these in turn affect consumers' food preference and performance. Indirect effects of global stressors like OA can be equally or more important than the direct effects predicted in the literature.

Undernutrition and quality of life.

Gabr, M

Malnutrition, the most pervasive human problem especially in less developed countries (LDCs), not only adversely affects quality of life but also socioeconomic development. 25% of pregnant women in LDCs suffer from protein energy malnutrition while only 4% do in developed countries. This and other forms of malnutrition cause low birth weight infants and consequently high infant mortality and morbidity rates and limited fetal brain development. Child mortality due to measles is 200-400 times greater in malnourished children in LDCs than those in developed countries. In addition, measles brings about acute malnutrition in marginally nourished children. Malnutrition also adversely affects fertility, such as reducing a woman's fecundity during the menstrual cycle. Studies demonstrate that severe malnutrition during the 1st 6 months of life and maybe up to the 1st 2 years impairs intellectual development and the effects cannot be reversed. However, breast milk provides adequate nutrition and protects infants from infection when they are most susceptible. Inadequately nourished children are often apathetic, nonresponsive, impulsive; exhibit nongoal directed behavior; do not respond normally in social interactions; and cannot cope with stress or frequent daily demands. Studies indicate that even inadequately nourished adults develop behavior patterns similar to those of malnourished children. A starvation period among adults reduces muscle strength by almost 30% and precision of movements by 15-20%. In addition, childhood malnutrition reduces adult body weight and therefore restricting working capacity. The known effects of malnutrition should convince policy makers of the need to invest in programs that improve the nutritional standards of the populace for humanitarian reasons and to stimulate economic growth.

The chronic social defeat stress (CSDS) mouse model is a potentially useful system for understanding stress responses to social environments. We previously developed a mouse model of subchronic and mild social defeat stress (sCSDS) that exhibits increased body weight gain and food intake following polydipsia-like features. sCSDS mice also show avoidance behavior in a social interaction test. In this study, we examined the effects of diet quality on susceptibility to sCSDS by feeding these mice semi- and non-purified diets. Male C57BL/6J (B6; n = 82) mice were exposed to sCSDS using male ICR mice. The B6 mice were divided into four test groups: semi-purified pellet diet + sCSDS, non-purified pellet diet + sCSDS, semi-purified diet + control (no sCSDS), and non-purified diet + control. Although increased body weight, and food and water intake following sCSDS exposure were consistently observed in the groups that were fed semi- and non-purified diets, social avoidance behavior was influenced by food type (i.e., sCSDS mice fed semi-purified diet showed the greatest social avoidance behavior). In addition, the rates of stress susceptibility were estimated at 73.9 and 34.8% in sCSDS mice fed semi-purified and non-purified diets, respectively (P < 0.05). For comparison, the susceptible-like phenotype rates were estimated at 12.5 and 8.3% in healthy control mice fed semi-purified and non-purified diets, respectively. These results suggest that diet quality affects the vulnerability of mice to social defeat stress.

Transient dynamics in trial-offer markets with social influence: Trade-offs between appeal and quality

We study a trial-offer market where consumers may purchase one of two competing products. Consumer preferences are affected by the products quality, their appeal, and their popularity. While the asymptotic convergence or stationary states of these, and related dynamical systems, has been vastly studied, the literature regarding the transitory dynamics remains surprisingly sparse. To fill this gap, we derive a system of Ordinary Differential Equations, which is solved exactly to gain insight into the roles played by product qualities and appeals in the market behavior. We observe a logarithmic tradeoff between quality and appeal for medium and long-term marketing strategies: The expected market shares remain constant if a decrease in quality is followed by an exponential increase in the product appeal. However, for short time horizons, the trade-off is linear. Finally, we study the variability of the dynamics through Monte Carlo simulations and discover that low appeals may result in high levels of variability. The model results suggest effective marketing strategies for short and long time horizons and emphasize the significance of advertising early in the market life to increase sales and predictability.

A robust body of research has identified school transitions during adolescence, and in particular the transition from middle to high school, as one of the riskiest phases for school failure, being characterized by significant social, emotional and behavioral changes. This transition is critical even with respect to academic achievement: in Italy, the highest frequency of school dropout can be observed in the 9th and 10th grades, partly as a consequence of poor adjustment to the new school context. The impact of students' relationships with their teachers may be particularly relevant during critical developmental periods. Indeed, student-teacher relationships have been widely recognized as protective factors in school adjustment and, in case of negative relationships, also as a factor that increases the risk of maladjustment. Positive and affective student-teacher relationships may play an important role in students' adaptation to the school environment, favoring both academic achievement and adaptive behaviors. The aim of this study was to investigate the effects of the quality of teacher-student relationships, as perceived by pupils, on academic achievement, and problem and prosocial behaviors during the relevant school transition. The sample consisted of 122 students (55% female). We employed a self-report questionnaire to collect information on: demographic characteristics, quality of the relationship with teachers, problem and prosocial behaviors, and academic achievement. Students filled in the questionnaires twice: once during the 8th grade and 1 year later, during their first year of high school (9th grade). Regression analyses indicated that both average and varying levels of closeness with teachers significantly predicted changes in academic achievement: A perceived increase in closeness in 9th grade, as well as a higher mean closeness level, was associated with an increase in academic achievement. In turn, an increase in the level of perceived conflict with teachers significantly predicted an increase in conduct problems and hyperactive behaviors. This study supports the significance of student-teacher relationships as a protective factor during students' transition to high-school. Our findings also highlight the importance of relationship quality in preventing students' risk of school failure. PMID:28066305

This research applied a lifespan developmental framework to the study of sexual behavior among late adolescents by examining monthly covariations of penetrative and oral sex with positive and negative affect across the first year of university. Participants were 177 Canadian students who completed baseline questionnaires, followed by six monthly, web-based questionnaires assessing sexual behaviors and affect. Multilevel analyses revealed an average positive relation between oral sex and positive affect. Of six variables, five predicted individual differences in covariation between sex and affect: psychosocial maturity (immature and semi-mature status), attitudes toward sex, prior sexual experience, and living situation. During months when participants reported sexual behavior, psychosocially mature students reported more positive affect than did less mature students; students with more permissive attitudes reported more positive affect than did students with less permissive attitudes; students with no penetrative sexual experience reported more positive affect than students who had penetrative sexual experience; and living away from parents was associated with less negative affect. Implications for further study of sexual behavior from a developmental perspective are discussed.

The present study explored early personality and environmental predictors of the development of young children's empathy, as well as relations of empathy to prosocial behavior with peers at a later age. How children manage their own emotions and behaviors when under stress--their ego-resiliency--would be expected to affect their responses to others' emotions. Also, socialization experiences, such as the quality of parenting behaviors, have been associated with individual differences in empathy-related responding. We examined whether mothers' emotion socialization practices and children's ego-resiliency at 18 months predicted initial levels and change in empathy across five time points (24, 30, 42, 48, and 54 months; N = 242), and whether empathy in turn predicted prosocial behavior with peers at 72/84 months of age. Ego-resiliency and mothers' expressive encouragement both uniquely predicted the intercept of empathy. Boys' empathy was lower than girls' but improved more with age. Initial levels and growth of empathy positively predicted later prosocial behavior. Children's ego-resiliency predicted the slope of empathy at near significance (p = .054). We also found that the intercept of empathy mediated the relation between ego-resiliency and prosocial behavior as well as the relation between mothers' expressive encouragement and prosocial behavior. These findings suggest that both parenting and personality characteristics are relevant to the development of empathy during early childhood and might contribute to children's later prosocial behavior with peers.

Background: Health literacy is one of the most important priorities for improving health care quality through enhancing patient-provider communication. Implementing health literacy strategies enable nurses to provide information and instructions for patients in a manner that is more commensurate and understandable. The purpose of this study was to investigate the factors affecting nurses’ intention to implement health literacy strategies in patient education based on theory of planned behavior. Methods: A cross-sectional study was done on 148 nurse practitioners of AL-Zahra educational hospital in Isfahan, Iran, using a descriptive-analytic method. Data collected via a standardized questionnaire based on theory of planned behavior constructed and analyzed by SPSS v.17 using ANOVA, Independent T-test, Pearson correlation and linear regression. Results: There was statistically significant correlation between using health literacy strategies and marriage status, attending in retraining courses, employment type, job history, and job status. Perceived behavioral control was the most powerful predictor of intention (β=0.417) and use health literacy strategies in patient education and behavior of nurses (β=0.33). Conclusion: According to the findings of this study, perceived behavioral control is a powerful determinant of nurses’ intention and behavior of using health literacy strategies in patient education. Hence we recommend nurse educators to pay special attention to the constructs of this theory mainly perceived behavioral control in retrain courses about patient education and health literacy strategies.

Developmental theories of borderline personality disorder (BPD) posit that transactions between child characteristics and adverse environments, especially those in the context of the parent-child relationship, shape and maintain symptoms of the disorder over time. However, very little empirical work has investigated the role of parenting and parent-child transactions that may predict BPD severity over time. We examined maternal and dyadic affective behaviors during a mother-adolescent conflict discussion task as predictors of the course of BPD severity scores across 3 years in a diverse, at-risk sample of girls (N = 74) oversampled for affective instability and their biological mothers. Adolescent girls completed a structured conflict discussion task with their mothers at age 16. Girls' self-reported BPD severity scores were assessed annually from ages 15 to 17. Mother-adolescent interactions were coded using a global rating system of maternal and dyadic affective behaviors. Results from multilevel linear mixed models indicated that positive maternal affective behavior (i.e., supportive/validating behavior, communication skills, autonomy-promoting behavior, and positive affect) and positive dyadic affective behaviors (i.e., satisfaction and positive escalation) were associated with decreases in girls' BPD severity scores over time. Dyadic negative escalation was associated with higher overall levels of BPD severity scores, but negative maternal affective behavior (i.e., negative affect, dominance, conflict, and denial) was not. These findings suggest that the mother-daughter context is an important protective factor in shaping the course of BPD severity scores during adolescence and may be valuable in assessment, intervention, and prevention efforts.

Building on a social identity framework, our cross-level process model explains how a manager's servant leadership affects frontline employees' service performance, measured as service quality, customer-focused citizenship behavior, and customer-oriented prosocial behavior. Among a sample of 238 hairstylists in 30 salons and 470 of their customers, we found that hair stylists' self-identity embedded in the group, namely, self-efficacy and group identification, partially mediated the positive effect of salon managers' servant leadership on stylists' service performance as rated by the customers, after taking into account the positive influence of transformational leadership. Moreover, group competition climate strengthened the positive relationship between self-efficacy and service performance. PsycINFO Database Record (c) 2015 APA, all rights reserved.

Rewarding healthy behaviors--pay patients for performance.

PubMed

Wu, Joanne

2012-01-01

Despite a considerable investment of resources into pay for performance, preliminary studies have found that it may not be significantly more effective in improving health outcome measures when compared with voluntary quality improvement programs. Because patient behaviors ultimately affect health outcomes, I would propose a novel pay-for-performance program that rewards patients directly for achieving evidence-based health goals. These rewards would be in the form of discounts towards co-payments for doctor's visits, procedures, and medications, thereby potentially reducing cost and compliance issues. A pilot study recruiting patients with diabetes or hypertension, diseases with clear and objective outcome measures, would be useful to examine true costs, savings, and health outcomes of such a reward program. Offering incentives to patients for reaching health goals has the potential to foster a stronger partnership between doctors and patients and improve health outcomes.

Outcome measures for clinical rehabilitation trials: impairment, function, quality of life, or value?

PubMed

Wade, Derick T

2003-10-01

Choosing outcome measures in rehabilitation research depends on the standard research skills of clear thinking, attention to detail, and minimizing the amount of data collected. In rehabilitation, outcome is more difficult to measure because (1) usually several outcomes are relevant, (2) relevant outcomes are affected by multiple factors in addition to treatment, and (3) even good measures rarely reflect the specific interest of any individual patient or member of the rehabilitation team, leading to some dissent. Measurement of general quality of life is not possible because there is little agreement as to the nature of the construct; moreover, measurement of relevant aspects of quality of life would probably give similar results. Cost in terms of resources can be estimated, but there is no validated or even widely accepted method of relating this to benefit in a fair, open, and rational way. Outcome is best measured at the level of behavior (activities), with other measures being used to aid interpretation.
