    Introduction: The puerperium is a stage that produces changes and adaptations in women, couples and family. Effective coping, during this stage, depends on the relationship between the demands of stressful or difficult situations and the recourses that the puerperal individual has. Roy (2004), in her Middle Range Theory about the Coping and Adaptation Processing, defines Coping as the ''behavioral and cognitive efforts that a person makes to meet the environment demands''. For the puerperal individual, the correct coping is necessary to maintain her physical and mental well being, especially against situations that can be stressful like breastfeeding and return to work. According to Lazarus and Folkman (1986), a resource for coping is to have someone who receives emotional support, informative and / or tangible. Objective: To review the issue of women coping and adaptation during the puerperium stage and the strategies that enhance this adaptation. Methods: search and selection of database articles: Cochrane, Medline, Ovid, ProQuest, Scielo, and Blackwell Synergy. Other sources: unpublished documents by Roy, published books on Roy´s Model, Websites from of international health organizations. Results: the need to recognize the puerperium as a stage that requires comprehensive care is evident, where nurses must be protagonist with the care offered to women and their families, considering the specific demands of this situation and recourses that promote effective coping and the family, education and health services.

    Breast cancer diagnosis and treatment represent stressful events that demand emotional adjustment, thus recruiting coping strategies and defense mechanisms. As parental relations were shown to influence emotion regulation patterns and adaptive processes in adulthood, the present study investigated whether they are specifically associated to coping and defense mechanisms in patients with breast cancer. One hundred and ten women hospitalized for breast cancer surgery were administered questionnaires assessing coping with cancer, defense mechanisms, and memories of parental bonding in childhood. High levels of paternal overprotection were associated with less mature defenses, withdrawal and fantasy and less adaptive coping mechanisms, such as hopelessness/helplessness. Low levels of paternal care were associated with a greater use of repression. No association was found between maternal care, overprotection, coping and defense mechanisms. Immature defenses correlated positively with less adaptive coping styles, while mature defenses were positively associated to a fighting spirit and to fatalism, and inversely related to less adaptive coping styles. These data suggest that paternal relations in childhood are associated with emotional, cognitive, and behavioral regulation in adjusting to cancer immediately after surgery. Early experiences of bonding may constitute a relevant index for adaptation to cancer, indicating which patients are at risk and should be considered for psychological interventions.

    Defence mechanisms and coping strategies rely on different theoretical backgrounds and describe distinct psychological processes. Cramer has based a distinction on the following dimensions: conscious processes vs. not; intentionality vs. not; hierarchical conception vs. not. On the contrary to these distinctions, the two notions of defense mechanisms and coping strategies are defined as similar in the Diagnostical and Statistical Manual (DSM IV). This assimilation between coping and defenses in the DSM IV is not confirmed by some researches, namely the one by Callahan and Chabrol. It indeed proves a relationship between adaptive coping and mature defenses, as well as between maladaptive coping and immature defenses. Similarly, Plutchik offered theoretical correspondences between eight defense mechanisms and eight coping strategies: (a) Defenses: repression, isolation, introjection and Coping escape; (b) Defense denial and Coping minimalization; (c) Defense undoing and coping substitution; (d) Defenses: regression, acting out and coping social support; (e) Defenses: compensation, identification, fantasy and coping replacement; (f) Defenses: intellectualization, sublimation, annulation, rationalisation and coping: planification; (g) Defense projection and coping blame; (h) Defense: reactional formation and coping inversion. this research aims at testing the relations observed by Callahan and Chabrol and some theoretical correspondences proposed by Plutchik between defences and coping strategies in a population of students similar to the one used by Callahan and Chabrol. It also aims at studying the relationships between coping strategies and conscious derives of defense mechanisms, such as defined by Bond (1995). Defenses were evaluated the first day of the examination week. the population includes 184 women students in human sciences (sociology and psychology). defenses were evaluated with the Defense Style Questionnaire by Bond (DSQ 40).

    Academic buoyancy refers to a positive, constructive, and adaptive response to the types of challenges and setbacks experienced in a typical and everyday academic setting. In this project we examined whether academic buoyancy explained any additional variance in test anxiety over and above that explained by coping. Two hundred and ninety-eight students in their final two years of compulsory schooling completed self-report measures of academic buoyancy, coping, and test anxiety. Results suggested that buoyancy was inversely related to test anxiety and unrelated to coping. With the exception of test-irrelevant thoughts, test anxiety was positively related to avoidance coping and social support. Test-irrelevant thoughts were inversely related to task focus, unrelated to social support, and positively related to avoidance. A hierarchical regression analysis showed that academic buoyancy explained a significant additional proportion of variance in test anxiety when the variance for coping had already been accounted for. These findings suggest that academic buoyancy can be considered as a distinct construct from that of adaptive coping.

    Employees commonly report feeling stressed at work. Examine how employees cope with work and personal stress, whether their coping strategies are adaptive (protective to health) or maladaptive (detrimental to health), and if the manner in which employees cope with stress influences perceived stress management. In this cross-sectional study, a random sample of 2,500 full-time university non-student employees (i.e. faculty, salaried professionals, and hourly non-professionals) were surveyed on health related behaviors including stress and coping. Approximately 1,277 completed the survey (51% ). Hierarchical logistic regression was used to assess the ability of adaptive and maladaptive coping strategies to predict self-reported stress management, while controlling for multiple demographic variables. Over half of employees surveyed reported effective stress management. Most frequently used adaptive coping strategies were communication with friend/family member and exercise, while most frequently used maladaptive coping strategies were drinking alcohol and eating more than usual. Both adaptive and maladaptive coping strategies made significant (p < 0.05) contributions to predicting employee's perceived stress management. Only adaptive coping strategies (B = 0.265) predicted whether someone would self-identify as effectively managing stress. Use of maladaptive coping strategies decreased likelihood of self-reporting effective stress management. Actual coping strategies employed may influence employees' perceived stress management. Adaptive coping strategies may be more influential than maladaptive coping strategies on perceived stress management. Results illustrate themes for effective workplace stress management programs. Stress management programs focused on increasing use of adaptive coping may have a greater impact on employee stress management than those focused on decreasing use of maladaptive coping. Coping is not only a reaction to stressful experiences but also

    This study examined longitudinal changes in coping and defense mechanisms in an age- and gender-stratified sample of 392 European-American adults. Nonlinear age-related changes were found for the coping mechanisms of sublimation and suppression and the defense mechanisms of intellectualization, doubt, displacement, and regression. The change trajectories for sublimation and suppression showed that their use increased from adolescence to late middle age and early old age, and remained mostly stable into late old age. The change trajectory for intellectualization showed that the use of this defense mechanism increased from adolescence to middle age, remained stable until late midlife, and started to decline thereafter. The defense mechanisms of doubt, displacement, and regression showed decreases from adolescence until early old age, with increases occurring again after the age of 65. Linear age-related decreases were found for the coping mechanism of ego regression and the defense mechanisms of isolation and rationalization. Gender and socioeconomic status were associated with the mean levels of several coping and defense mechanisms, but did not moderate age-related changes. Increases in ego level were associated with increased use of the defense mechanism intellectualization and decreased use of the defense mechanisms of doubt and displacement. Overall, these findings in a European-American sample suggest that most individuals showed development in the direction of more adaptive and less maladaptive coping and defense strategies from adolescence until late middle age or early old age. However, in late old age this development was reversed, presenting potential challenges to the adaptive capacity of older adults. PMID:23834293

    Adaptive coping strategies are associated with less psychological distress. However, there is no brief, specific, and validated instrument for assessing adaptive coping among seriously ill patients. Our objective was to examine the validity and patient-proxy agreement of a novel instrument, the Sickness Insight in Coping Questionnaire. A cross-sectional design which included two related studies. A single university-affiliated Dutch hospital. Hospitalized patients (study 1) and ICU-patients and proxies (study 2). None. Study 1 (n = 103 hospitalized patients) addressed the Sickness Insight in Coping Questionnaire's performance relative to questionnaires addressing similar content areas. Coping subscales of the BRIEF COPE, Illness Cognition Questionnaire, and Utrecht Coping List were used as comparator measures in testing the construct validity of the Sickness Insight in Coping Questionnaire-subscales (fighting spirit, toughness, redefinition, positivism, and non-acceptance). The Sickness Insight in Coping Questionnaire had good internal consistency (0.64 ≤ α ≤ 0.79), a clear initial factor structure, and fair convergent (0.24 ≤ r ≤ 0.50) and divergent (r, ≤ 0.12) construct validity. Study 2 examined the performance of the Sickness Insight in Coping Questionnaire among 100 ICU patients and their close family members. This study showed that the Sickness Insight in Coping Questionnaire has good structural validity (confirmatory factor analyses with Comparative Fit Index > 0.90 and Root Mean Square Error of Approximation < 0.08) and moderate (r, 0.37; non-acceptance) to strong (r, > 0.50; fighting spirit, toughness, redefinition, and positivism) patient-close proxy agreement. Overall, the Sickness Insight in Coping Questionnaire has good psychometric properties. ICU clinicians can use the Sickness Insight in Coping Questionnaire to gain insight in adaptive coping style of patients through ratings of patients or their close family members.

    Coping is a psychological process that prompts the individual to adapt to stressful situations. The Adolescent Coping Scale is a widely used research and clinical tool. This study aimed to develop a Portuguese version of the Adolescent Coping Scale and to analyze the strategies and coping styles of young people in our sample. An anonymous questionnaire comprising the Adolescent Coping Scale was submitted and replied by 1 713 students (56% female, from 12 to 20 years, average age 16) The validity study of the scale included: principal component and reliability analysis; confirmatory analysis using structural equation modelling Subsequently, a gender comparison of both the strategies and the coping styles was conducted through independent samples t tests. The final structure of the Adolescent Coping Scale adaptation retained 70 items assessing 16 coping strategies grouped into three major styles. The scales showed good internal consistency (Cronbach alpha values between 0.63. and 0.86, with the exception of one dimension that as shown a value of 0.55) and the confirmatory model showed a good fit (goodness of fit index values between 0.94 e 0.96). Two coping strategies were eliminated on statistical grounds (insufficient saturations of items in the corresponding dimensions). We found that the style of coping focused on problem solving is the most used by youths from our sample, in both sexes. Females had higher mean values in non-productive coping style and reference to others. This adapted version has high similarity with the original scale, with expectable minor changes, given that coping is influenced by cultural, geographical and socio-economic variables. The present study represents an important part of the validation protocol Portuguese Adolescent Coping Scale, including its linguistic adaptation and its internal consistency and factor structure studies.

    Lack of adaptive and enhanced maladaptive coping with stress and negative emotions are implicated in many psychopathological disorders. We describe the development of a new scale to investigate the relative contribution of different coping styles to psychopathology in a large population sample. We hypothesized that the magnitude of the supposed positive correlation between maladaptive coping and psychopathology would be stronger than the supposed negative correlation between adaptive coping and psychopathology. We also examined whether distinct coping style patterns emerge for different psychopathological syndromes. A total of 2200 individuals from the general population participated in an online survey. The Patient Health Questionnaire-9 (PHQ-9), the Obsessive-Compulsive Inventory revised (OCI-R) and the Paranoia Checklist were administered along with a novel instrument called Maladaptive and Adaptive Coping Styles (MAX) questionnaire. Participants were reassessed six months later. MAX consists of three dimensions representing adaptive coping, maladaptive coping and avoidance. Across all psychopathological syndromes, similar response patterns emerged. Maladaptive coping was more strongly related to psychopathology than adaptive coping both cross-sectionally and longitudinally. The overall number of coping styles adopted by an individual predicted greater psychopathology. Mediation analysis suggests that a mild positive relationship between adaptive and certain maladaptive styles (emotional suppression) partially accounts for the attenuated relationship between adaptive coping and depressive symptoms. Results should be replicated in a clinical population. Results suggest that maladaptive and adaptive coping styles are not reciprocal. Reducing maladaptive coping seems to be more important for outcome than enhancing adaptive coping. The study supports transdiagnostic approaches advocating that maladaptive coping is a common factor across different psychopathologies

  14. Adaptive Capacity in Tanzanian Maasailand: Changing strategies to cope with drought in fragmented landscapes

    This study examines the ways in which the adaptive capacity of households to climatic events varies within communities and is mediated by institutional and landscape changes. We present qualitative and quantitative data from two Maasai communities differentially exposed to the devastating drought of 2009 in Northern Tanzania. We show how rangeland fragmentation combined with the decoupling of institutions and landscapes are affecting pastoralists ability to cope with drought. Our data highlight that mobility remains a key coping mechanism for pastoralists to avoid cattle loss during a drought. However, mobility is now happening in new ways that require not only large amounts of money but new forms of knowledge and connections outside of customary reciprocity networks. Those least affected by the drought, in terms of cattle lost, were those with large herds who were able to sell some of their cattle and to pay for private access to pastures outside of Maasai areas. Drawing on an entitlements framework, we argue that the new coping mechanisms are not available to all, could be making some households more vulnerable to climate change, and reduce the adaptive capacity of the overall system as reciprocity networks and customary institutions are weakened. As such, we posit that adaptive capacity to climate change is uneven within and across communities, is scale-dependent, and is intimately tied to institutional and landscape changes. PMID:25400331

    The purpose of this study was to identify the potentially distinct defense profiles of athletes in order to provide insight into the complex associations that can exist between defenses and other important variables tied to performance in sports (e.g., coping, perceived stress and control) and to further our understanding of the complexity of the adaptation process in sports. Two hundred and ninety-six (N = 296) athletes participated in a naturalistic study that involved a highly stressful situation: a sports competition. Participants were assessed before and after the competition. Hierarchical cluster analysis and a series of MANOVAs with post hoc comparisons indicated two stable defense profiles (high and low defense profiles) of athletes both before and during sport competition. These profiles differed with regards to coping, stress and control. Athletes with high defense profiles reported higher levels of coping strategies, perceived stress and control than athletes with low defense profiles. This study confirmed that defenses are involved in the psychological adaptation process and that research and intervention should not be based only on coping, but rather must include defense mechanisms in order to improve our understanding of psychological adaptation in competitive sports.

    The purpose of the study was to build a model to explain the relationships between social support, uncontrollability appraisal, adaptive coping, and posttraumatic growth (PTG) among cancer patients in China. The participants who were cancer patients in a cancer hospital in China filled out a survey. The final sample size was 201. Structural equation modeling was used to build a model explaining PTG. Structural equation modeling results indicated that higher levels of social support predicted higher levels of adaptive coping, higher levels of uncontrollability appraisal predicted lower levels of adaptive coping, and higher levels of adaptive coping predicted higher levels of PTG. Moreover, adaptive coping was a mediator between social support and growth, as well as a mediator between uncontrollability and growth. The direct effects of social support and uncontrollability on PTG were insignificant. The model demonstrated the relationships between social support, uncontrollability appraisal, adaptive coping, and PTG. It could be concluded that uncontrollability appraisal was a required but not sufficient condition for PTG. Neither social support nor uncontrollability appraisal had direct influence on PTG. However, social support and uncontrollability might indirectly influence PTG, through adaptive coping. It implies that both internal factors (eg, cognitive appraisal and coping) and external factors (eg, social support) are required in order for growth to happen.

    The adjustment to higher education can be understood as a multidimensional process, which requires by the student a development of adaptive skills to a new and dynamic context in itself. To meet these challenges students have to develop effective coping strategies, enabling them to be adapted to the context.

    Qualitative research methods allowed the investigator to contribute to the development of new theories and to examine change in processes over time, which added rich detail to existing knowledge of the use of coping and adaptive strategies by traumatic brain injury survivors and their primary caregivers (Ponsford, Sloan, & Snow, 2013). The advantages of phenomenological study were that it allows flexibility to explore and understand meanings attached by people to well-studied concepts such as coping, resiliency, and adaptation or compensation. Phenomenological study was sensitive to contextual factors. It also permitted the study of in-depth dynamics of coping and adaptive strategies of TBI survivors and primary caregivers, while understanding the social and psychological implications of the phenomenon. To explore the needs and deficits of adult traumatic brain injury (TBI) survivors and primary caregivers; and to identify their self-initiated coping and adaptive strategies. Significant to this study was the development of coping and adaptive strategies by the participants after their discharge from inpatient and rehabilitation treatment. The compensatory skills taught in treatment settings did not transfer to the home environment. Therefore, these strategies developed independently from previous treatment recommendations contributed to the development of theory related to rehabilitation and counseling. Distinctive to this study was the similarity of coping and adaptive strategies developed from both mild and severe traumatic brain injury survivors. This study consisted of eleven with TBI and six primary caregivers (N = 17), who participated in a series of semi-structured interviews aimed at discovering the coping and adaptive strategies utilized in dealing with the effects of brain injury. A Qualitative Phenomenological design was employed. Patience and understanding, support, and professional help were identified by TBI survivors and caregivers as being their

    Studying the evolution of coping and adaptation capacities is a prerequisite for preparing an effective flood management plan for the future, especially in the dynamic and fast changing cities of developing countries. The objectives, requirements, targets, design and performance of flood protection measures will have to be determined after taking into account, or in conjunction with, the coping capacities. A methodology is presented based on adaptation pathways to account for coping capacities and to assess the effect on flood protection measures. The adaptation pathways method determines the point of failure of a particular strategy based on the change in an external driver, a point in time or a socio economic situation where / at which the strategy can no longer meet its objective. Pathways arrived at based on this methodology reflect future reality by considering changing engineering standards along with future uncertainties, risk taking abilities and adaptation capacities. This pathways based methodology determines the Adaptation tipping points (ATP), `time of occurrence of ATP' of flood protection measures after accounting for coping capacities, evaluates the measures and then provides the means to determine the adaptation pathways. Application of this methodology for flood protection measures in Can Tho city in the Mekong delta reveals the effect of coping capacity on the usefulness of flood protection measures and the delay in occurrence of tipping points. Consideration of coping capacity in the system owing to elevated property floor levels lead to the postponement of tipping points and improved the adaptation pathways comprising flood protection measures such as dikes. This information is useful to decision makers for planning and phasing of investments in flood protection.

  4. Coping styles and behavioural flexibility: towards underlying mechanisms

    2010-01-01

    A coping style (also termed behavioural syndrome or personality) is defined as a correlated set of individual behavioural and physiological characteristics that is consistent over time and across situations. This relatively stable trait is a fundamental and adaptively significant phenomenon in the biology of a broad range of species, i.e. it confers differential fitness consequences under divergent environmental conditions. Behavioural flexibility appears to be an important underlying attribute or feature of the coping style that might explain consistency across situations. Proactive coping is characterized by low flexibility expressed as rather rigid, routine-like behavioural tendencies and reduced impulse control (behavioural inhibition) in operant conditioning paradigms. This article summarizes some of the evidence that individual differentiation in behavioural flexibility emerges as a function of underlying variability in the activation of a brain circuitry that includes the prefrontal cortex and its key neurochemical signalling pathways (e.g. dopaminergic and serotonergic input). We argue that the multidimensional nature of animal personality and the terminology used for the various dimensions should reflect the differential pattern of activation of the underlying neuronal network and the behavioural control function of its components. Accordingly, unravelling the molecular mechanisms that give rise to individual differences in the coping style will be an important topic in biobehavioural neurosciences, ecology and evolutionary biology.

    This 6 month prospective study systematically tested some multivariate models that advanced the understanding of the psychological mechanisms underlying Internet addiction and psychosocial maladjustment. On the basis of previous theories, avoidant coping and coping inflexibility were proposed as underlying mechanisms. Participants were 271 Chinese undergraduates (75% women, Mage=20.49) who took part in both phases of this study. Structural equation modeling was performed to obtain the best fit models for both the cross-sectional and the prospective data. The cross-sectional model testing revealed statistically significant mediating effects for both avoidant coping (β=0.149 [95% CI 0.071-0.226], p=0.002) and coping flexibility (β=0.048 [95% CI 0.013-0.081], p=0.032). The prospective model testing further showed that avoidant coping mediated the relationship between Internet addiction and Time 2 psychosocial maladjustment (β=0.141 [95% CI 0.065-0.216], p=0.005), as well as that between coping flexibility and Time 2 psychosocial maladjustment (β=-0.096 [95% CI -0.161 to -0.031], p=0.015). This study was the first to establish theory-driven models, which unveiled an inflexible, avoidant coping style as psychological mechanisms that explained the link between Internet addiction and psychosocial maladjustment.

  7. Does coping help? A reexamination of the relation between coping and mental health.

    1987-08-01

    In a longitudinal community survey of 291 adults, we explored the relation between coping strategies and psychological symptoms. Respondents completed the revised Ways of Coping Scale (Folkman & Lazarus, 1985) for a self-named stressful episode. Factor analysis produced eight coping factors: three problem focused, four emotion focused, and one (support mobilization) that contained elements of both. Multiple regression analyses indicated bidirectionality in the relation between coping and psychological symptoms. Those in poorer mental health and under greater stress used less adaptive coping strategies, such as escapism, but coping efforts still affected mental health independent of prior symptom levels and degree of stress. We compared main versus interactive effects models of stress buffering. Main effects were confined primarily to the emotion-focused coping scales and showed little or negative impacts of coping on mental health; interactive effects, though small, were found with the problem-focused scales. The direction of the relation between problem-focused scales and symptoms may depend in part on perceived efficacy, or how the respondent thought he or she handled the problem. Implications for the measurement of adaptive coping mechanisms and their contextual appropriateness are discussed.

    Considerable individual differences exist in trait-like patterns of behavioral and physiological responses to salient environmental challenges. This individual variation in stress coping styles has an important functional role in terms of health and fitness. Hence, understanding the neural embedding of coping style variation is fundamental for biobehavioral neurosciences in probing individual disease susceptibility. This review outlines individual differences in trait-aggressiveness as an adaptive component of the natural sociobiology of rats and mice, and highlights that these reflect the general style of coping that varies from proactive (aggressive) to reactive (docile). We propose that this qualitative coping style can be disentangled into multiple quantitative behavioral domains, e.g., flexibility/impulse control, emotional reactivity and harm avoidance/reward processing, that each are encoded into selective neural circuitries. Since functioning of all these brain circuitries rely on fine-tuned serotonin signaling, autoinhibitory control mechanisms of serotonergic neuron (re)activity are crucial in orchestrating general coping style. Untangling the precise neuromolecular mechanisms of different coping styles will provide a roadmap for developing better therapeutic strategies of stress-related diseases.

    Given the continuous, dynamic demographic changes internationally due to intensive worldwide migration and globalization, the need to more fully understand how migrants adapt and cope with acculturation experiences in their new host cultural environment is imperative and timely. However, a comprehensive review of what we currently know about the relationship between coping behavior and acculturation experience for individuals undergoing cultural changes has not yet been undertaken. Hence, the current article aims to compile, review, and examine cumulative cross-cultural psychological research that sheds light on the relationships among coping, acculturation, and psychological and mental health outcomes for migrants. To this end, this present article reviews prevailing literature pertaining to: (a) the stress and coping conceptual perspective of acculturation; (b) four theoretical models of coping, acculturation and cultural adaptation; (c) differential coping pattern among diverse acculturating migrant groups; and (d) the relationship between coping variabilities and acculturation levels among migrants. In terms of theoretical understanding, this review points to the relative strengths and limitations associated with each of the four theoretical models on coping-acculturation-adaptation. These theories and the empirical studies reviewed in this article further highlight the central role of coping behaviors/strategies in the acculturation process and outcome for migrants and ethnic populations, both conceptually and functionally. Moreover, the review shows that across studies culturally preferred coping patterns exist among acculturating migrants and migrant groups and vary with migrants' acculturation levels. Implications and limitations of the existing literature for coping, acculturation, and psychological adaptation research are discussed and recommendations for future research are put forth.

    Statement of problem A new fabrication process has been developed where a titanium coping, which has a gold colored titanium nitride outer layer can be reliably fused to porcelain, but the marginal adaptation characteristics are still undetermined. Purpose The primary purpose of this study is to compare the rate of Clinically Acceptable Marginal Adaptation (CAMA-defined as a marginal gap mean ≤60 μm) of cathode-arc vapor-deposited titanium with the CAMA rate for the cast base metal copings. In addition, the study will evaluate the marginal gap scores themselves to assess their mean difference between the two study groups. Finally, the study will present two analyses of group differences in variability to support the contention that the titanium copings perform more consistently than their base metal counterparts. Material and methods Thirty-seven cathode-arc vapor-deposited titanium copings and 40 cast base metal copings were evaluated by computer-based image analysis using an optical microscope. The conventional lost wax technique was used to fabricate the 40 cast base metal copings that were 0.3 mm thick. The titanium copings were 0.3 mm thick and were formed by a collection of atomic titanium vapor onto a refractory die duplicate in a high vacuum chamber. Fifty vertical marginal gap measurements were collected from each of the 77 copings and the mean of these measurements was computed to form a gap score for each coping. Next, the gap score was compared to the 60 μm criterion to classify each coping as to whether it did or did not achieve Clinically Acceptable Marginal Adaption (CAMA). A comparison of the CAMA rates for each type of coping was used to address the primary purpose of this study. In addition, the gap scores themselves were used to test the (one-sided) hypothesis that the mean of the titanium gap scores is smaller than the mean of the base metal gap scores. Finally, the assertion that the titanium copings provide more consistency in their

    Reser, Joseph P; Swim, Janet K

    2011-01-01

    This article addresses the nature and challenge of adaptation in the context of global climate change. The complexity of "climate change" as threat, environmental stressor, risk domain, and impacting process with dramatic environmental and human consequences requires a synthesis of perspectives and models from diverse areas of psychology to adequately communicate and explain how a more psychological framing of the human dimensions of global environmental change can greatly inform and enhance effective and collaborative climate change adaptation and mitigation policies and research. An integrative framework is provided that identifies and considers important mediating and moderating parameters and processes relating to climate change adaptation, with particular emphasis given to environmental stress and stress and coping perspectives. This psychological perspective on climate change adaptation highlights crucial aspects of adaptation that have been neglected in the arena of climate change science. Of particular importance are intra-individual and social "psychological adaptation" processes that powerfully mediate public risk perceptions and understandings, effective coping responses and resilience, overt behavioral adjustment and change, and psychological and social impacts. This psychological window on climate change adaptation is arguably indispensable to genuinely multidisciplinary and interdisciplinary research and policy initiatives addressing the impacts of climate change.

    Aim To retrospectively analyze the rate of multi-type abuse in childhood and the effects of childhood abuse and type of coping strategies on the psychological adaptation of young adults in a sample form the student population of the University of Mostar. Methods The study was conducted on a convenience sample of 233 students from the University of Mostar (196 female and 37 male), with a median age of 20 (interquartile range, 2). Exposure to abuse was determined using the Child Maltreatment Scales for Adults, which assesses emotional, physical, and sexual abuse, neglect, and witnessing family violence. Psychological adaptation was explored by the Trauma Symptom Checklist, which assesses anxiety/depression, sexual problems, trauma symptoms, and somatic symptoms. Strategies of coping with stress were explored by the Coping Inventory for Stressful Situations. Results Multi-type abuse in childhood was experienced by 172 participants (74%) and all types of abuse by 11 (5%) participants. Emotional and physical maltreatment were the most frequent types of abuse and mostly occurred together with other types of abuse. Significant association was found between all types of abuse (r = 0.436-0.778, P < 0.050). Exposure to sexual abuse in childhood and coping strategies were significant predictors of anxiety/depression (R2 = 0.3553), traumatic symptoms (R2 = 0.2299), somatic symptoms (R2 = 0.2173), and sexual problems (R2 = 0.1550, P < 0.001). Conclusion Exposure to multi-type abuse in childhood is a traumatic experience with long-term negative effects. Problem-oriented coping strategies ensure a better psychosocial adaptation than emotion-oriented strategies. PMID:20960590

    No study to date has evaluated the relationship between coping style, burnout, and psychological functioning among gastroenterologists (GEs). This study aims to explore this relationship. Physician stress and burnout are widely studied and associated with notably poorer outcomes for both physicians and their patients. Coping is a multidimensional construct that individuals use to adapt to stressful situations. To mitigate stress, physicians may use problem-focused or emotion-focused coping strategies. Four hundred ten GE fellows and attending physicians provided information about their practice, coping styles, level of burnout, psychological distress, job-related self-efficacy, and demographic background. Participants recruited from the American Society of Gastrointestinal Endoscopy membership through email completed a series of online questionnaires. We found no significant relationships between workload and reported burnout. GEs with greater psychological distress were more likely to have an endoscopic complication in the past year. GEs that use problem-focused coping strategies were less likely to report an event in the past year, although we did not identify a significant predictive relationship between these variables. Significant differences in coping styles existed for sex and having a physician parent. Female GEs were more likely to use problem-focused coping strategies, and GEs with a physician parent were more likely to use emotion-focused strategies. Using problem-focused coping predicted decreased levels of burnout and psychological distress, and increased job-related self-efficacy. Emotion-focused coping showed opposite predictive results. Coping strategies accounted for 3% to 19% of the variance in these outcomes. GEs use both problem-focused and emotion-focused coping strategies. Sex and having a physician parent are likely predictors of coping and psychological well-being. Problem-focused coping is a potentially more adaptive coping strategy in

    The problem of coping with stress is an important one in the context of development and persistence of alcohol dependence. In the literature to date very little attention has been paid to coping patterns construed as a configuration of specific coping styles, particularly as regards the functioning of addicted individuals. The aim of the study was to verify whether individuals with alcohol dependence characterized by different coping patterns differ with respect to the severity of psychopathological symptoms, defense mechanisms and time perspectives. Participants were given a battery of psychological tests-Coping Inventory for Stresfull Situations (CISS), Defense Style Questionnaire (DSQ 40), Syndrom Checklist (SCL-90) and Short Zimbardo Time Perspective Inventory (SZPTI-PL). The sample comprised 112 individuals with alcohol dependence, aged 20 to 63 years old, the average age was 37.86; 78 percent were men. There were identified three sub-groups of individuals characterized by a distinctive patterns of coping with stress -"emotional-avoidant", "task oriented" and a "mixed one". Individuals with the predominant emotional-avoidant coping pattern are characterized by significantly higher severity of psychopathological symptoms, less mature defense mechanisms and past time perspectives. Subjects reliant on task-oriented coping pattern were characterized by the highest level of adaptation and the most constructive way of functioning in the face of difficulties. It is worth regarding the examination of patterns of coping as an indispensable element of collecting medical history from alcohol dependent individuals.

    Between 1989 and 2005, Israel absorbed over a million new immigrants, about 90% of whom were from the Former Soviet Union (FSU). The present study investigated the adaptation of these FSU new immigrants in a sample of 301 participants (67% women, ages 25-45 years), who completed inventories measuring personal resources (tolerance of ambiguity and cognitive flexibility), cognitive appraisals (of employment, language, and housing problems), coping strategies, well-being, distress, and willingness to remain in Israel. A structural equation modeling (SEM) analysis showed that tolerance for ambiguity and cognitive flexibility contributed positively to control appraisals, task-oriented coping, and level of participant well-being, and negatively to threat/loss appraisals, emotion/avoidance-oriented coping, and distress. Control appraisals contributed to task-oriented coping, whereas threat/loss appraisals contributed to both emotion/avoidance-oriented and task-oriented coping. Control and challenge appraisals, and task-oriented coping, contributed positively to participant willingness to remain in Israel, whereas emotion/avoidance-oriented coping contributed positively to distress levels, which in turn were negatively related to willingness to remain in Israel. The results of this study have significant implications for such aspects of immigrant adaptation as absorption policies and the provision of individual care by professionals and organizations.

    The aim of this in vitro study was to investigate the effect of Shoulder versus Chamfer margin design on the marginal adaptation of zirconia (Zr) copings. 40 extracted molar teeth were mounted in resin and prepared for zirconia crowns with two margin preparation designs (20=Shoulder and 20=Chamfer). The copings were manufactured by Cercon® (DeguDent GmbH, Germany) using the CAD/CAM system for each tooth. They were tried on each tooth, cemented, thermocycled, re-embedded in resin and were subsequently cross sectioned centrally into two equal mesial and distal halves. They were examined under electron microscope at 200 X magnification and the measurements were recorded at 5 predetermined points in micrometers (µm). The o verall mean marginal gap for the two groups was found to be 206.98+42.78µm with Shoulder margin design (Marginal Gap=199.50+40.72µm) having better adaptation compared to Chamfer (Marginal Gap=214.46+44.85µm). The independent-samples t-test showed a statistically non-significant difference (p=.113) between the means of marginal gap for Shoulder and Chamfer margin designs and the measurements were recorded at 5 predetermined points for the two groups. The Chamfer margin design appeared to offer the same adaptation results as the Shoulder margin design.

    In couples parenting children with Autism Spectrum Disorder (ASD), the partner becomes a primary source of support for addressing the additional parenting demands. The purpose of this study was to examine the associations between supportive dyadic coping and parental adaptation, and to assess the mediating role of relationship satisfaction between them. Seventy-six couples parenting children with ASD participated. Data were gathered through self-report questionnaires and an Actor-Partner Interdependence Mediation Model was used. Mothers' and fathers' supportive dyadic coping was related to both their own and partner's relationship satisfaction and parental adaptation. Findings also revealed the mediation role of relationship satisfaction, in the association between supportive dyadic coping and parental adaptation. The implications for research and clinical practice are discussed.

    To examine the predictive value of cognitive coping strategies at pretreatment and the value of changes in these strategies during cognitive-behavioral treatment for aviophobia for long-term therapy results. Data from baseline, after therapy at 2 months, short-term follow-up at 5 months, and long-term follow-up at 41 months were analyzed (N = 59). Participants were in a long-term process of change, which continued positively after therapy for maladaptive cognitive coping strategies. The use of cognitive coping strategies at baseline was not predictive of long-term outcome. However, a greater increase in the use of adaptive coping strategies, and more importantly, a greater decrease in the use of maladaptive coping strategies were predictive of improvements indicated in self-report of flight anxiety and actual flight behavior at long-term follow-up. Improvement of maladaptive cognitive coping strategies is possibly a key mechanism of change in cognitive-behavioral therapy for aviophobia. © 2016 Wiley Periodicals, Inc.

    To test whether the coping in deliberation (CODE) framework can be adapted to a specific preference-sensitive medical decision: risk-reducing bilateral salpingo-oophorectomy (RRSO) in women at increased risk of ovarian cancer. We performed a systematic literature search to identify issues important to women during deliberations about RRSO. Three focus groups with patients (most were pre-menopausal and untested for genetic mutations) and 11 interviews with health professionals were conducted to determine which issues mattered in the UK context. Data were used to adapt the generic CODE framework. The literature search yielded 49 relevant studies, which highlighted various issues and coping options important during deliberations, including mutation status, risks of surgery, family obligations, physician recommendation, peer support and reliable information sources. Consultations with UK stakeholders confirmed most of these factors as pertinent influences on deliberations. Questions in the generic framework were adapted to reflect the issues and coping options identified. The generic CODE framework was readily adapted to a specific preference-sensitive medical decision, showing that deliberations and coping are linked during deliberations about RRSO. Adapted versions of the CODE framework may be used to develop tailored decision support methods and materials in order to improve patient-centred care. Copyright © 2014 Elsevier Ireland Ltd.

    2015-09-29

    South Africa is at present undertaking a series of reforms to transform public health services to make them more effective and responsive to patient and provider needs. A key focus of these reforms is primary care and its overburdened, somewhat dysfunctional and hierarchical nature. This comparative case study examines how patients and providers respond in this system and cope with its systemic demands through mechanisms of endurance, resistance and resilience, using coping and agency literatures as the theoretical lenses. As part of a larger research project carried out between 2009 and 2010, this study conducted semi-structured interviews and observations at health facilities in three South African provinces. This study explored patient experiences of access to health care, in particular, ways of coping and how health care providers cope with the health care system's realities. From this interpretive base, four cases (two patients, two providers) were selected as they best informed on endurance, resistance and resilience. Some commentary from other respondents is added to underline the more ubiquitous nature of these coping mechanisms. The cases of four individuals highlight the complexity of different forms of endurance and passivity, emotion- and problem-based coping with health care interactions in an overburdened, under-resourced and, in some instances, poorly managed system. Patients' narratives show the micro-practices they use to cope with their treatment, by not recognizing victimhood and sometimes practising unhealthy behaviours. Providers indicate how they cope in their work situations by using peer support and becoming knowledgeable in providing good service. Resistance and resilience narratives show the adaptive power of individuals in dealing with difficult illness, circumstances or treatment settings. They permit individuals to do more than endure (itself a coping mechanism) their circumstances, though resistance and resilience may be limited. These

    Qualitative research is important due to the shortage of literature in understanding cultural influences on psychosocial and mental health syndromes and their presentation, especially in developing countries. This qualitative study aims to investigate the psychosocial and mental health needs of populations in Aceh, Indonesia affected by over 30 years of conflict, their dysfunction, and their positive coping mechanisms. Results from this qualitative assessment indicate the presence of depression, anxiety and somatic symptoms. The data provide local terminology and ways in which the local population describes their own distress, which is an important addition to the understanding of the mental health consequences of this conflict. The data has been used to develop appropriate intervention strategies and adapt and validate assessment tools to measure psychological distress, dysfunction and coping mechanisms.

    The present study aims to compare and evaluate the marginal fit and axial wall adaptability of Co-Cr copings fabricated by metal laser sintering (MLS) and lost-wax (LW) techniques using a stereomicroscope. A stainless steel master die assembly was fabricated simulating a prepared crown; 40 replicas of master die were fabricated in gypsum type IV and randomly divided in two equal groups. Group A coping was fabrication by LW technique and the Group B coping fabrication by MLS technique. The copings were seated on their respective gypsum dies and marginal fit was measured using stereomicroscope and image analysis software. For evaluation of axial wall adaptability, the coping and die assembly were embedded in autopolymerizing acrylic resin and sectioned vertically. The discrepancies between the dies and copings were measured along the axial wall on each halves. The data were subjected to statistical analysis using unpaired t -test. The mean values of marginal fit for copings in Group B (MLS) were lower (24.6 μm) than the copings in Group A (LW) (39.53 μm), and the difference was statistically significant ( P < 0.05). The mean axial wall discrepancy value was lower for Group B (31.03 μm) as compared with Group A (54.49 μm) and the difference was statistically significant ( P < 0.05).

    According to the dual-process theory of coping flexibility (Kato, 2012), coping flexibility is the ability to discontinue an ineffective coping strategy (i.e., evaluation coping process) and implement an alternative strategy (i.e., adaptive coping process). The coping flexibility hypothesis (CFH) proposes that the ability to engage in flexible coping is related to better psychological functioning and physical health, including less depression. I the present study, participants were 393 American Whites, 429 Australian Whites, and 496 Chinese, selected from the data pool of the 2013 Coping and Health Survey (see Kato, 2014b). They completed both the Coping Flexibility Scale (Kato, 2012), which is based on the dual-process theory of coping flexibility, and the Center for Epidemiologic Studies Depression Scale (CES-D). For all nationalities and genders, evaluation coping and adaptive coping were significantly correlated with lower levels of depressive symptoms. Structural equation modeling revealed that evaluation coping was associated with lower depressive symptoms for all nationalities and genders, whereas no significant relationships between adaptive coping and depressive symptoms were found for any nationalities. Our results partially supported that the CFH fits with the dual-process theory of coping flexibility. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    The authors examined the moderating effects of coping tactics on the relationship between negative emotion and work performance. Findings indicate an adverse effect of emotion on performance; however, this effect is moderated by coping tactics. Venting (expressing one's negative feelings to others) amplified the adverse effects of negative emotion. Self-control had mixed effects: On one hand, it buffered the adverse effects of negative emotion, yet on the other hand, it had a negative direct effect on outcomes. Task focus had a positive direct effect on performance but no buffering (moderating) effect. Implications of these findings for understanding the effects of negative emotion and coping in the workplace are discussed. Copyright 2005 APA, all rights reserved.

    2009-01-01

    This prospective study analyzes the coping mechanisms of police officers directly after an event of potential traumatic nature in the line of duty (e. g. use of firearms) as well as 6 months later. 59 police officers were contacted by professional crisis intervention teams of the police force. After an extended interview, an ICD-10 diagnosis, if applicable, was assigned. Six months later a diagnosis was derived by a clinician (Diplom-Psychologe) using a structured interview. Coping strategies were accessed by the FKV (Freiburger Fragebogen zur Krankheitsverarbeitung) questionnaire. Fourteen police officers (28%) received the diagnosis of a PTSD (ICD-10: F43.1) at 6 months. The coping mechanisms of the traumatized police officers were significantly elevated in a dysfunctional manner in the areas "emotional control and social retreat" (only directly after the event), "regression", "mistrust and pessimism", and "depressive processing". Because dysfunctional coping mechanisms impede the decline of the symptoms, it may be considered adequate to strengthen the coping mechanisms for functional coping with these symptoms, thereby focusing on the dysfunctional coping strategy specific to the police force, namely, emotional control.

    2015-11-01

    Adolescents who endorse greater levels of future orientation report greater well-being over time, but we do not know the mechanism by which this happens. The present longitudinal study examined whether both adaptive as well as maladaptive coping strategies might explain how future orientation leads to ill-being and well-being over time in young New Zealanders. A sample of 1,774 preadolescents and early adolescents (51.9 % female) aged 10-15 years at Time 1 completed a self-report survey three times with 1 year intervals in between. Longitudinal mediation path models were constructed to determine whether and how maladaptive and adaptive coping strategies at Time 2 functioned as mediators between future orientation at Time 1 and ill-being and well-being at Time 3. Results showed that future orientation predicted lower maladaptive coping, which in turn predicted lower substance use and self-harming behavior. All three well-being outcomes (i.e., happiness with weight, vitality, and sleep) were consistently predicted by future orientation, and all three pathways were mediated by both lower maladaptive and higher adaptive coping strategies (with the exception of happiness with weight, which was mediated only by lower maladaptive coping). The results suggest that several pathways by which future orientation leads to greater well-being occurs through an increased use of adaptive coping, a decreased use of maladaptive coping, or both.

    The aim of this study was to report: (1) an analysis of the concepts of coping, adaptation and self-management in the context of managing a neurological condition; and (2) the overlap between the concepts. The three concepts are often confused or used interchangeably. Understanding similarities and differences between concepts will avoid misunderstandings in care. The varied and often unpredictable symptoms and degenerative nature of neurological conditions make this an ideal population in which to examine the concepts. Concept analysis. Articles were extracted from a large literature review about living with a neurological condition. The original searches were conducted using SCOPUS, EMBASE, CINAHL and Psych INFO. Seventy-seven articles met the inclusion criteria of: (1) original article concerning coping, adaptation or self-management of a neurological condition; (2) written in English; and (3) published between 1999-2011. The concepts were examined according to Morse's concept analysis method; structural elements were then compared. Coping and adaptation to a neurological condition showed statistically significant overlap with a common focus on internal management. In contrast, self-management appears to focus on disease-controlling and health-related management strategies. Coping appears to be the most mature concept, whereas self-management is least coherent in definition and application. All three concepts are relevant for people with neurological conditions. Healthcare teams need to be cautious when using these terms to avoid miscommunication and to ensure clients have access to all needed interventions. Viewing the three concepts as a complex whole may be more aligned with client experience. © 2016 John Wiley & Sons Ltd.

    Parkinson's disease (PD) is a chronic neurodegenerative disease that can render individuals totally disabled. Spiritual practices can help mitigate stress and provide a source of strength in PD. This article demonstrates a gap that exists between PD and spiritual coping specific research; discusses existing spiritual coping research in chronic illness; and explores the use of spirituality in managing PD care. Healthcare providers need to provide holistic care and explore mechanisms to assist individuals to manage the demands of living with PD.

    It is estimated that 70% of individuals with factor VIII deficiency hemophilia who received blood products before 1985 are infected with human immunodeficiency virus (HIV). The goal of the current study was to assess how adolescents with hemophilia cope with reminders of their HIV status, because adaptation is likely to have implications for these individuals' quality of life and adherence to safer sex recommendations. Participants included 297 HIV-positive adolescents with hemophilia who were recruited from 11 sites across the United States. Adolescents reported on the use and effectiveness of strategies for coping with reminders of their HIV status. A significant degree of distress was reported in response to such reminders, with anger being the most commonly reported emotion. Although a wide variety of coping strategies had been tried, participants reported using resignation (80.9%), self-calming (78.8%), and distraction (76.4%) most frequently in their attempts to cope with reminders of HIV. Self-blame (3.6%), engaging in risky behaviors (22.2%), thinking about sex (25.4%), and drug/alcohol use (29.1%) were used least. These adolescents tended to rate more active cognitive and behavioral coping strategies (eg, cognitive restructuring, seeking social support, physical activity) as most effective, whereas passive strategies (eg, wishful thinking, blaming others) were reported to be least helpful. Those individuals who reported being distressed by reminders of HIV endorsed most of the coping strategies significantly more often than the nondistressed group, although ineffective strategies were commonly chosen. Sexually active adolescents were more likely than their abstinent peers to cope by thinking about sex, engaging in risky behaviors, or using alcohol and drugs. In this population of adolescents who have known their serostatus for several years, distress about everyday reminders of HIV appears to be associated with ineffective coping strategies.

    The primary objective of this 2-year pilot study was to evaluate the effectiveness of a culturally adapted family intervention in improving family communication among African American parents coping with cancer and their school-age children. A secondary objective was to determine its impact on other symptoms of psychosocial distress (depression and anxiety). The third objective was to assess for acceptability and feasibility. Using a two-arm pre-intervention and post-intervention prospective design, 12 African American families received five bi-monthly sessions of either a culturally adapted family intervention (n=7 families) or psycho-education treatment (n=5 families). Parents and their children completed pre-intervention and post-intervention questionnaires assessing perceptions of family communication, quality of their relationship, and symptoms of depression. School-age children additionally completed a questionnaire assessing their levels of anxiety. Consumer satisfaction was also evaluated at post-intervention. Parents and school-age children who completed the culturally adapted family intervention reported significantly better communication with each other and were more satisfied compared with the psycho-education control group. No changes were noted in symptoms of anxiety or depression. The culturally adapted family intervention was acceptable based on our findings, families' feedback, and rates of retention. Feasibility is uncertain because our oncology clinic approach to recruitment was slower than expected. Providing culturally adapted family intervention programs to African American families who are coping with parental cancer may result in improved family communication. This pilot study serves as the first step in the development of culturally adapted family intervention programs to help African American families cope with parental cancer.

    2012-01-01

    Chronic illnesses and medical conditions present millions of children and adolescents with significant stress that is associated with risk for emotional and behavioral problems and interferes with adherence to treatment regimens. We review research on the role of child and adolescent coping with stress as an important feature of the process of adaptation to illness. Recent findings support a control-based model of coping that includes primary control or active coping (efforts to act on the source of stress or one’s emotions), secondary control or accommodative coping (efforts to adapt to the source of stress), and disengagement or passive coping (efforts to avoid or deny the stressor). Evidence suggests the efficacy of secondary control coping in successful adaptation to chronic illness in children and adolescents, disengagement coping is associated with poorer adjustment, and findings for primary control coping are mixed. Avenues for future research are highlighted. PMID:22224836

    2012-11-01

    Although the quality of parent-adolescent emotional bonds has consistently been proposed as a major influence on young adult's psycho-emotional functioning, the precise means by which these bonds either facilitate or impede adaptive coping are not well-understood. In an effort to advance this inquiry, the present study examined interrelationships among measures of parental attachment, emotion regulation processes, and preferred coping strategies within a sample of 942 college freshmen. Structural Equation Modelling was used to test whether the link between attachment to parents and the use of particular coping strategies is mediated by differences in emotion regulation mechanisms. As hypothesized, differences in attachment to parents predicted differences in the use of emotion regulation mechanisms and coping strategies. More specifically, having a close emotional bond, feeling supported in autonomy processes and having (moderately) low levels of separation anxiety toward parents predict more constructive emotion regulation mechanisms and coping strategies. Additionally emotion regulation was found to (partly or totally) mediate the association between attachment and coping.

  10. Adaptation Mechanisms in the Evolution of Moss Defenses to Microbes

    2017-01-01

    Bryophytes, including mosses, liverworts and hornworts are early land plants that have evolved key adaptation mechanisms to cope with abiotic stresses and microorganisms. Microbial symbioses facilitated plant colonization of land by enhancing nutrient uptake leading to improved plant growth and fitness. In addition, early land plants acquired novel defense mechanisms to protect plant tissues from pre-existing microbial pathogens. Due to its evolutionary stage linking unicellular green algae to vascular plants, the non-vascular moss Physcomitrella patens is an interesting organism to explore the adaptation mechanisms developed in the evolution of plant defenses to microbes. Cellular and biochemical approaches, gene expression profiles, and functional analysis of genes by targeted gene disruption have revealed that several defense mechanisms against microbial pathogens are conserved between mosses and flowering plants. P. patens perceives pathogen associated molecular patterns by plasma membrane receptor(s) and transduces the signal through a MAP kinase (MAPK) cascade leading to the activation of cell wall associated defenses and expression of genes that encode proteins with different roles in plant resistance. After pathogen assault, P. patens also activates the production of ROS, induces a HR-like reaction and increases levels of some hormones. Furthermore, alternative metabolic pathways are present in P. patens leading to the production of a distinct metabolic scenario than flowering plants that could contribute to defense. P. patens has acquired genes by horizontal transfer from prokaryotes and fungi, and some of them could represent adaptive benefits for resistance to biotic stress. In this review, the current knowledge related to the evolution of plant defense responses against pathogens will be discussed, focusing on the latest advances made in the model plant P. patens.

  11. The use of hope as a coping mechanism in abused women.

    PubMed

    Marden, M O; Rice, M J

    1995-03-01

    The purpose of this study was to identify how abused women use hope and to determine whether hope is a coping mechanism in their relationship with the abusers. Four focus group sessions were conducted with a sample of 24 women using a phenomenological methodology. The data analysis indicated that abused women maintain hope in four major dimensions: hope for change in their partner's behavior, hope for survival, hope as something to cling to, and hope for control of the situation. The subjects stated that hope was used as a coping mechanism to help them keep their sanity; but in this context, the subjects often saw hope as false or unreal. Thus some abused women used hope as a mechanism to attempt to resolve cognitive dissonance between their internal beliefs and the external reality of physical violence.

    Few qualitative studies have examined the views of adolescents with type 1 diabetes mellitus (T1DM) regarding psychosocial programme development and content. We conducted focus groups with 13 adolescents with T1DM to explore stressors and gain feedback on adapting a generic coping skills programme. The following prevalent stressors were identified: parental/adolescent conflict, balancing self-management and daily life, and health concerns. Prevalent views on programme adaptation included enhancing social support and adding diabetes-specific information and skills. Based on these data, the programme was adapted to address stressors and support self-management, thus better meeting the needs of, and appeal to, adolescents with T1DM.

    Positive emotions, such as gratitude has been found to be beneficial to both physical and mental well-being but so far, drug misuse research has yet to identify important emotive predictors related to drug use. This study aimed to examine the relationship between gratitude and drug use among a group of drug misusers. It was hypothesized that greater dispositional gratitude was associated with lesser drug use through greater use of adaptive coping methods and lesser use of maladaptive coping methods. This study utilized a cross-sectional design to examine the relationship between gratitude, coping, and drug use among a sample of drug misusers (N = 105) at a drug rehabilitation center. Participants completed the gratitude questionnaire (GQ-6), the joy subscale of the Dispositional Positive Emotion Scale (DPES), the Brief COPE, and a questionnaire on their drug use. Data were collected in 2015. Mediation analysis supported the hypothesis and found that adaptive coping mediated the relationship between gratitude and drug use. However, mediation was not found for maladaptive coping. Additional analysis found that adaptive coping as a mediator was not found for joy. Results suggested that gratitude has utility in reducing drug use through the use of more adaptive coping strategies and this relationship was not simply due to positive affect. Interventions targeting drug use behavior could consider introducing gratitude to increase adaptive coping abilities to reduce drug use.

  14. Mitigation of climate change impacts on raptors by behavioural adaptation: ecological buffering mechanisms

    The predicted climate change causes deep concerns on the effects of increasing temperatures and changing precipitation patterns on species viability and, in turn, on biodiversity. Models of Population Viability Analysis (PVA) provide a powerful tool to assess the risk of species extinction. However, most PVA models do not take into account the potential effects of behavioural adaptations. Organisms might adapt to new environmental situations and thereby mitigate negative effects of climate change. To demonstrate such mitigation effects, we use an existing PVA model describing a population of the tawny eagle ( Aquila rapax) in the southern Kalahari. This model does not include behavioural adaptations. We develop a new model by assuming that the birds enlarge their average territory size to compensate for lower amounts of precipitation. Here, we found the predicted increase in risk of extinction due to climate change to be much lower than in the original model. However, this "buffering" of climate change by behavioural adaptation is not very effective in coping with increasing interannual variances. We refer to further examples of ecological "buffering mechanisms" from the literature and argue that possible buffering mechanisms should be given due consideration when the effects of climate change on biodiversity are to be predicted.

    Cyberbullying is a relatively new form of bullying. This bullying is committed by means of an electronic act, the transmission of a communication by message, text, sound, or image by means of an electronic device, including but limited to, a computer phone, wireless telephone, or other wireless communication device, computer, games console or pager. Cyberbullying is characterized by deliberately threatening, harassing, intimidating, or ridiculing an individual or group of individuals; placing an individual in reasonable fear of harm; posting sensitive, private information about another person without his/her permission; breaking into another person's account and/or assuming another individual's identity in order to damage that person's reputation or friendships. A review of the literature shows that between 6 and 40% of all youths have experienced cyberbullying at least once in their lives. Several cyberbullying definitions have been offered in the literature, many of which are derived from definitions of traditional bullying. In our study we asked clear definition of cyberbullying. Few studies explicate the psychosocial determinants of cyberbullying, and coping mechanisms. The authors of the literature recommend developing resiliency, but without analyzing the resilience factor. The first aim of this study was to determine the prevalence of adolescents and adults engaged in cyberbullying. The second aim was to examine the coping mechanisms and comorbidity factors associated with the cyberbullied people. The sample was composed of 272 adolescents (from a high school) and adults (mean age=16.44 ± 1). The Olweus Bully/Victim Questionnaire was used to identify profiles of cyberbullying. Coping mechanisms were investigated using the Hurt Disposition Scale (HDS) and the Brief Resilience Scale (BRS). Comorbidities were assessed using the Hospital Anxiety and Depression Scale (HAD), Liebowitz's Social Anxiety Scale (LSAS), and the Bermond-Vorst Alexithymia Questionnaire

    Football is played worldwide and players often have to cope with hot and cold temperatures as well as high altitude conditions. The upcoming and past world championships in Brazil, Qatar and South Africa illustrate the necessity for behavioural strategies and adaptation to extreme environmental conditions. When playing football in the heat or cold, special clothing, hydration and nutritional and acclimatisation strategies are vital for high-level performance. When playing at high altitude, the reduced oxygen partial pressure impairs endurance performance and alters the technical and tactical requirements. Special high-altitude adaptation and preparation strategies are essential for football teams based at sea-level in order to perform well and compete successfully. Therefore, the aim of the underlying review is: 1) to highlight the difficulties and needs of football teams competing in extreme environmental conditions, 2) to summarise the thermoregulatory, physiological, neuronal and psychological mechanism, and 3) to provide recommendations for coping with extreme environmental conditions in order to perform at a high level when playing football in the heat, cold and at high altitude. © Georg Thieme Verlag KG Stuttgart · New York.

    1997-01-01

    We designed this study to clarify the role of work stress on long-term blood pressure control and in particular to investigate whether perceived work stress directly affected resting blood pressure levels or whether there were indirect effects mediated by coping mechanisms and lifestyle. Men (n = 337) and women (n = 317) working in a government tax office completed questionnaires for assessment of work-related stress, coping strategies, and lifestyle. Seven resting blood pressure measurements were recorded serially on each of two occasions a week apart. Men had higher blood pressures (119.6/68.6 versus 110.9/65.6 mm Hg) than women; they used more "maladaptive" coping strategies, drank more alcohol, and ate less healthily but exercised more than women. There were no direct associations between measures of work stress and blood pressure. In univariate and regression analyses, both body mass index and lifestyle factors in the form of alcohol consumption, exercise, and diet were related to blood pressure in men and women. Various "adaptive" or "maladaptive" coping mechanisms were identified and independently related to both job stress and blood pressure levels. Women were more likely to use "healthier" or adaptive coping mechanisms than men. Thus, work stress per se had no direct effect on blood pressure, but the ways that individuals reported coping with stress were significantly related to blood pressure, with blood pressure elevation effects appearing to be mediated largely by dietary and drinking habits and physical inactivity. The results point to the need to target individual coping strategies and lifestyle as much as the working environment in workplace cardiovascular health promotion programs.

  18. The Impact of Coping Flexibility on the Risk of Depressive Symptoms

    PubMed Central

    Kato, Tsukasa

    2015-01-01

    Objective According to the dual-process theory, coping flexibility is defined as the ability to produce and implement a new coping strategy in place of an ineffective coping strategy. Specifically, coping flexibility includes two processes: evaluation coping and adaptive coping. Evaluation coping refers to sensitivity to feedback about the efficacy of a coping strategy, and adaptive coping involves the willingness to implement alternative coping strategies. The coping flexibility hypothesis (CFH) postulates that more flexible coping will be associated with more adaptive outcomes; importantly, there are numerous theories and studies that support the CFH. The main purpose of this study was to test the CFH based on dual-process theory. Methods A total of 1,770 Japanese college students participated and, completed a set of questionnaires that measured coping flexibility (evaluation coping and adaptive coping) and depressive symptoms. Depressive symptoms were measured via the Center for Epidemiologic Studies Depression Scale. Results The proportions of women and men who reported depressive symptoms were 58.69% (95% CIs [55.74, 61.66]) and 54.17% (95% CIs [50.37, 57.95]), respectively when a cut-off score of 16 on the CES-D was used. A multivariable logistic regression analysis revealed that evaluation coping (OR = 0.86, 95% CIs [0.83, 0.0.89]) and adaptive coping (OR = 0.91, 95% CIs [0.88, 0.93]) were significantly associated with lower levels of depressive symptoms. Conclusion The results of the present study indicated that the CFH based on dual-process theory was supported in a Japanese sample. PMID:26011626

    Any defect in the extremities of the body can affect different life aspects. The purpose of this study was to investigate the effect of Roy's adaptation model-guided education on coping strategies of the veterans with lower extremities amputation. In a double-blind randomized controlled clinical trial, 60 veterans with lower extremities amputation referring to Kowsar Orthotics and Prosthetics Center of Veterans Clinic in Tehran, Iran were recruited using convenience method and randomly assigned to intervention and control groups in 2013-2014. Lazarus and Folkman coping strategies questionnaire was used to collect the data. After completing the questionnaires in both groups, maladaptive behaviours were determined in the intervention group and an education program based on Roy's adaptation model was implemented. After 2 months, both groups completed the questionnaires again. Data were analyzed using SPSS software. Independent T-test showed that the score of the dimensions of coping strategies did not have a statistically significant difference between the intervention and control groups in the pre-intervention stage (P>0.05). This test showed a statistically significant difference between the two groups in the post-intervention stage in terms of the scores of different dimensions of coping strategies (P>0.05), except in dimensions of social support seeking and positive appraisal (P>0.05). The findings of this research indicated that the Roy's adaptation model-guided education improved the majority of coping strategies in veterans with lower extremities amputation. It is recommended that further interventions based on Roy's adaptation model should be performed to improve the coping of the veterans with lower extremities amputation. IRCT2014081118763N1.

    This article describes the conceptual framework for the Coping Power program that has focused on proximal risk factors that can actively alter preadolescent children's aggressive behavior. The results of initial controlled efficacy trials are summarized. However, consistent with the theme of this special section, some clinicians and workshop participants have indicated barriers to the implementation of the Coping Power program in their service settings. In response to these types of concerns, three key areas of programmatic adaptation of the program that serve to address these concerns are then described in the article. First, existing and in-process studies of variations in how the program can be delivered are presented. Existing findings indicate how the child component fares when delivered by itself without the parent component, how simple monthly boosters affect intervention effects, and whether the program can be reduced by a third of its length and still be effective. Research planned or in progress on program variations examines whether group versus individual delivery of the program affects outcomes, whether the program can be adapted for early adolescents, whether the program can be delivered in an adaptive manner with the use of the Family Check Up, and whether a brief, efficient version of the program in conjunction with Internet programming can be developed and be effective. Second, the program has been and is being developed for use in different settings, other than the school-based delivery in the efficacy trials. Research has examined its use with aggressive deaf youth in a residential setting, with Oppositional Defiant Disorder and Conduct Disorder children in outpatient clinics, and in after-school programs. Third, the article reports how variations in training clinicians affect their ability to effectively use the program. PsycINFO Database Record (c) 2012 APA, all rights reserved.

    Stress responses entail neuroendocrine, autonomic, and behavioral changes to promote effective coping with real or perceived threats to one’s safety. While these responses are critical for the survival of the individual, adverse effects of repeated exposure to stress are widely known to have deleterious effects on health. Thus, a considerable effort in the search for treatments to stress-related CNS disorders necessitates unraveling the brain mechanisms responsible for adaptation under acute conditions and their perturbations following chronic stress exposure. This paper is based upon a symposium from the 2014 International Behavioral Neuroscience Meeting, summarizing some recent advances in understanding the effects of stress on adaptive and maladaptive responses subserved by limbic forebrain networks. An important theme highlighted in this review is that the same networks mediating neuroendocrine, autonomic, and behavioral processes during adaptive coping also comprise targets of the effects of repeated stress exposure in the development of maladaptive states. Where possible, reference is made to the similarity of neurobiological substrates and effects observed following repeated exposure to stress in laboratory animals and the clinical features of stress-related disorders in humans.

    To measure spirituality/religiousness and its relation to coping skills in patients with residual schizophrenia. Using a cross-sectional design, 103 persons with residual schizophrenia were assessed on Positive and Negative Syndrome Scale [PANSS] and Ways of Coping Checklist [WCC] to assess the repertoire of coping skills and WHO Quality of Life-Spirituality, Religiousness and Personal Belief scale [WHOQOL-SRPB] to assess religiousness and spirituality. Positive reappraisal as a coping strategy had significant positive correlation with all the facets of WHOQOL-SRPB and SRPB total domain scores. The coping subscales of accepting responsibility, planful problem solving, distancing, confrontive coping, and self-controlling also had significant positive correlations with different facets of WHOQOL-SRPB and total SRPB domain score. Seeking social support and escape-avoidance as coping mechanisms had no correlations with any of the WHOQOL-SRPB facets. A sound spiritual, religious, or personal belief system is associated with active and adaptive coping skills in subjects with residual schizophrenia. Understanding and assessing the spirituality and religiousness of subjects with schizophrenia can help in better management of the disorder.

    Trying to cope with chronic pain is a highly demanding and challenging task and pain patients often need to reformulate goals or aspirations due to their pain condition. This goal violation is often related with experienced distress and requires coping processes in order to decrease the distress and stimulate a healthy adaptation. Some scholars, however, argued that in so-called unsolvable or irreparable stressors such as chronic pain, conventional coping strategies like problem-focused coping might not be the most adaptive option. In these situations, meaningful coping strategies attempting to transform the meaning of the stressful experience would be more accurate. In this study, we aim to test if goal violation triggers meaningful coping strategies over time and whether engagement in these meaningful coping strategies result in improved life satisfaction, as an indicator of adaptation. A longitudinal three wave study in a sample of paint patients (n = 125) tests whether goal violation triggers positive reappraisal and downward comparison, two possible meaningful coping strategies. The study furthermore tests if engagement in these strategies results in a better adaptation to the pain condition, reflected in higher life satisfaction. Results partially supported our hypotheses by pointing to the benevolent role of downward comparison on life satisfaction via decreased goal violation of pain patients. Our findings however did also show that positive reappraisal predicted lower life satisfaction via increased levels of appraised goal violation which questions the role of positive reappraisal as a genuine meaningful coping strategy. Implications and limitations are discussed. © 2016 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    This study aimed at identifying the levels of adaptive problems among teenage female refugees in the government schools and explored the behavioral methods that were used to cope with the problems. The sample was composed of 220 Syrian female students (seventh to first secondary grades) enrolled at government schools within the Zarqa Directorate and who came to Jordan due to the war conditions in their home country. The study used the scale of adaptive problems that consists of four dimensions (depression, anger and hostility, low self-esteem, and feeling insecure) and a questionnaire of the behavioral adjustment methods for dealing with the problem of asylum. The results indicated that the Syrian teenage female refugees suffer a moderate degree of adaptation problems, and the positive adjustment methods they have used are more than the negatives.

    Of the primary responses to contemporary climate change – “move, adapt, acclimate, or die” – that are available to organisms, “acclimate” may be effectively achieved through behavioral modification. Behavioral flexibility allows animals to rapidly cope with changing environmental conditions, and behavior represents an important component of a species’ adaptive capacity in the face of climate change. However, there is currently a lack of knowledge about the limits or constraints on behavioral responses to changing conditions. Here, we characterize the contexts in which organisms respond to climate variability through behavior. First, we quantify patterns in behavioral responses across taxa with respect to timescales, climatic stimuli, life-history traits, and ecology. Next, we identify existing knowledge gaps, research biases, and other challenges. Finally, we discuss how conservation practitioners and resource managers can incorporate an improved understanding of behavioral flexibility into natural resource management and policy decisions.

    Despite often being considered equivalent affective states, shame and guilt have differential associations with problem gambling with only shame showing a strong positive association with problem gambling. However, little is known about the mechanisms underlying the shame-problem gambling association. Further, shame and guilt are associated with distinct coping strategies, with shame motivating maladaptive coping (e.g., avoidance, escape) and guilt motivating adaptive coping (e.g., taking corrective action). This study aimed to examine whether maladaptive coping motives for gambling mediate the relationship between shame, but not guilt, and gambling problems. Participants were 196 (126 male) regular gamblers who completed a same and guilt scale, the Problem Gambling Severity Index, and a modified Gambling Motives Questionnaire, which assessed individual motives to engage in gambling for coping, enhancement, or social reasons. Results indicated that coping motives for gambling fully mediated the relationship between shame and problem gambling severity, but did not mediate the association between guilt and problem gambling severity. Experiencing shame contributes to problem gambling as a result of gambling to cope with negative affect. Cultivating more adaptive strategies to cope with shame may be effective in preventing and treating problem gambling.

    This study assessed knowledge, prevalence, associated factors and mechanisms of coping with stress among bankers in Lagos State. It was a descriptive cross sectional study. A two stage sampling technique was used to select two hundred and twenty seven (227) respondents. Data was collected using a structured self administered questionnaire. The analysis was done using Epi-info version 2002 software and Chi Square was used to determine association between variables at p value 0.05. Fischer's Exact test was used where Chi-square was not valid. The age range of respondents was between 20 and 49 years while the mean age was 31.3 +/- 5.0 years. Only 3.6% had good level of knowledge about stress, 42.2% had fair level while more than half of the respondents had poor level of knowledge about stress (54.3%). Majority (67.0%) of the respondents were moderately stressed while one quarter (24.7%) were highly stressed. Majority (92.4%) of the respondents used good coping mechanisms though 69.5% of the respondents also used bad coping mechanisms. A greater proportion of those who had poor knowledge about stress were stressed or highly stressed (p = 0.002). A statistically significant association was also found between the departments in the bank and level of stress of the respondents (p = 0.002). The prevalence of stress was high among the bank workers studied. It is recommended that effective stress management programmes are implemented to address the problem of stress among bank workers.

    The purpose of this study is to theoretically develop and empirically examine a general coping theory model which explicates the indirect effects of key job-related techno-stressors on job exhaustion. Through this study, we show that techno-stress creators are detrimental to employee well-being and should be treated accordingly. Specifically, we first argue that key techno-stress creators on the job, namely techno-invasion and techno-overload, drive unpleasant states such as work-family conflict and distress. Next, we rely on general coping theory and argue that people respond to these states differently, but with both adaptive and maladaptive technology-specific coping strategies. Adaptive coping behaviors are argued to ultimately reduce work exhaustion, and maladaptive coping strategies are argued to increase it. The proposed model was tested and validated with structural equation modeling techniques applied to self-reported data obtained from a sample of 242 employees of a large organization in the United States. Implications for theory and practice are discussed.

    Previous research has shown that both alcohol use and jealousy are related to negative relationship outcomes. Little work, however, has examined direct associations between alcohol use and jealousy. The current study aimed to build upon existing research examining alcohol use and jealousy. More specifically, findings from current jealousy literature indicate that jealousy is a multifaceted construct with both maladaptive and adaptive aspects. The current study examined the association between maladaptive and adaptive feelings of jealousy and alcohol-related problems in the context of drinking to cope. Given the relationship between coping motives and alcohol-related problems, our primary interest was in predicting alcohol-related problems, but alcohol consumption was also investigated. Undergraduate students at a large Northwestern university (N = 657) in the US participated in the study. They completed measures of jealousy, drinking to cope, alcohol use, and alcohol-related problems. Analyses examined associations between jealousy subscales, alcohol use, drinking to cope, and drinking problems. Results indicated that drinking to cope mediated the association between some, but not all, aspects of jealousy and problems with alcohol use. In particular, the more negative or maladaptive aspects of jealousy were related to drinking to cope and drinking problems, while the more adaptive aspects were not, suggesting a more complex view of jealousy than previously understood.

    To examine the association between coping style and emotional adjustment following traumatic brain injury. Thirty three individuals who had sustained a traumatic brain injury (mean duration of posttraumatic amnesia = 32 days) between 1(1/2) months and almost 7 years previously. Coping Scale for Adults, Hospital Anxiety and Depression Scale, Rosenberg Self-Esteem Scale, State-Trait Anger Expression Inventory, and the Sickness Impact Profile. Approximately 50% of the sample reported clinically significant levels of anxiety and depression. Coping characterized by avoidance, worry, wishful thinking, self-blame, and using drugs and alcohol was associated with higher levels of anxiety, depression, and psychosocial dysfunction and lower levels of self-esteem. Coping characterized by actively working on the problem and using humor and enjoyable activities to manage stress was associated with higher self-esteem. Lower premorbid intelligence (measured via the National Adult Reading Test) and greater self-awareness (measured via the Self-Awareness of Deficits Interview) were associated with an increased rate of maladaptive coping. The strong association between the style of coping used to manage stress and emotional adjustment suggests the possibility that emotional adjustment might be improved by the facilitation of more adaptive coping styles. It is also possible that improving emotional adjustment may increase adaptive coping. The development and evaluation of interventions aimed at facilitating adaptive coping and decreasing emotional distress represent important and potentially fruitful contributions to enhancing long-term outcome following brain injury.

    Given the enormous economic burden of malaria in Nigeria and in sub-Saharan Africa, it is important to determine how different population groups cope with payment for malaria treatment. This paper provides new information about the differences in household coping mechanisms for expenditures on malaria treatment. The study was undertaken in two communities in Southeast Nigeria. A total of 200 exit interviews were conducted with patients and their care givers after consultation and treatment for malaria. The methods that were used to cope with payments for malaria treatment expenditures were determined. The coping mechanisms were disaggregated by socio-economic status (SES). The average expenditure to treat malaria was $22.9, which was all incurred through out-of- pocket payments. Some households used more than one coping method but none reported using health insurance. It was found that use of household savings (79.5%) followed by reduction in other household expenses (22.5%) were the most common coping methods. The reduction of other household expenses was significantly more prevalent with the average (Q4) SES group (p<0.05). . People used different coping strategies to take care of their malaria expenditures, which are mostly paid out-of-pocket. The average socio-economic household had to forego other basic household expenditures in order to cope with malaria illness; otherwise there were no other significant differences in the coping mechanisms across the different SES groups. This could be indicative of the catastrophic nature of malaria treatment expenditures. Interventions that will reduce the burden of malaria expenditures on all households, within the context of Universal Health Coverage are needed so as to decrease the economic burden of malaria on households.

    Recently, cyber-victimization has become an ever increasing concern for adolescents. Given the negative consequences of cyber-victimization, it is important to understand how adolescents learn strategies to cope (i.e., "coping socialization") with cyber-victimization. The purpose of this study is to understand common coping strategies reported by adolescents, identify from whom youth learn cyber-victimization coping strategies (coaching), and explore how coaching is associated with adolescents' self-reported use of coping. In a sample of 329 adolescents (49% male; 70% white), we found that positive coping strategies (e.g., problem solving, seeking social support) are used most frequently, and adolescents' perceptions of both parent and peer coping socialization is associated with self-reported use of coping. Interventionists can use this information to adapt interventions to include influential positive socializers.

    Validation of a translated, culturally adapted questionnaire. We developed a Korean version of the Chronic Pain Coping Inventory-42 (CPCI-42) by performing a cross-cultural adaptation, and evaluated its reliability and validity. The CPCI is widely used and validated instruments for measuring coping strategies in chronic pain. However, no validated and culturally adapted version was available in Asian countries. We assessed 142 patients with chronic low back pain using the CPCI-42 and measures of physical disability, pain, and quality of life. Results for 93 of the 142 patients exhibited test-retest reliability. The interval time of collecting retest data varied from 2 weeks to 1 month. Criterion validity was evaluated using correlations between the CPCI-42 and the Oswestry Disability Index, the Brief Pain Inventory, and the Short Form 36-item Health Survey (version 2.0). Construct validity was computed using exploratory factor analysis. The Korean version of the CPCI-42 had a high internal consistency (Cronbach's alpha >0.70) with the exception of results for task persistence and relaxation. Illness-focused coping (guarding, resting, asking for assistance) and other-focused coping (seeking social support) were most significantly correlated with Oswestry Disability Index, Brief Pain Inventory, and Short Form 36-item Health Survey, respectively. Outcomes for task persistence were contrary to other subscales in wellness-focused coping. Construct validity by factor analysis produced similar results to the original CPCI subscale. However, several factors showed cross-loading in 8 factor solutions. Despite linguistic and cultural differences, the Korean version of the CPCI-42 is overall a meaningful tool, and produces results sufficiently similar to the original CPCI-42.

    Bacteria use a number of mechanisms for coping with the toxic effects exerted by nitric oxide (NO) and its derivatives. Here we show that the flavohemoglobin encoded by the hmp gene has a vital role in an adaptive response to protect the soil bacterium Bacillus subtilis from nitrosative stress. We further show that nitrosative stress induced by the nitrosonium cation donor sodium nitroprusside (SNP) leads to deactivation of the transcriptional repressor NsrR, resulting in derepression of hmp. Nitrosative stress induces the sigma B-controlled general stress regulon. However, a sigB null mutant did not show increased sensitivity to SNP, suggesting that the sigma B-dependent stress proteins are involved in a nonspecific protection against stress whereas the Hmp flavohemoglobin plays a central role in detoxification. Mutations in the yjbIH operon, which encodes a truncated hemoglobin (YjbI) and a predicted 34-kDa cytosolic protein of unknown function (YjbH), rendered B. subtilis hypersensitive to SNP, suggesting roles in nitrosative stress management.

    The main objective of the project was to examine a proposed theoretical model of mindfulness mechanisms in sports. We conducted two studies (the first study using a cross-sectional design and the second a longitudinal design) to investigate if rumination and emotion regulation mediate the relation between dispositional mindfulness and sport-specific coping. Two hundred and forty-two young elite athletes, drawn from various sports, were recruited for the cross-sectional study. For the longitudinal study, 65 elite athletes were recruited. All analyses were performed using Bayesian statistics. The path analyses showed credible indirect effects of dispositional mindfulness on coping via rumination and emotion regulation in both the cross-sectional study and the longitudinal study. Additionally, the results in both studies showed credible direct effects of dispositional mindfulness on rumination and emotion regulation. Further, credible direct effects of emotion regulation as well as rumination on coping were also found in both studies. Our findings support the theoretical model, indicating that rumination and emotion regulation function as essential mechanisms in the relation between dispositional mindfulness and sport-specific coping skills. Increased dispositional mindfulness in competitive athletes (i.e. by practicing mindfulness) may lead to reductions in rumination, as well as an improved capacity to regulate negative emotions. By doing so, athletes may improve their sport-related coping skills, and thereby enhance athletic performance.

    Although stressful life events represent an etiologic factor of mental health problems in adolescents, few studies have been conducted to address mechanisms linking the stress-psychopathology relation. The present study was designed to examine coping as a mediate factor on the relationship between stressful life events and symptoms of anxiety and depression. The participants were 13 512 students from eight cities of China, who participated in a school-based survey. Data were collected by a questionnaire comprising coping, stressful life events, anxiety, and depressive symptoms. As a model, a series of regression equations were used to examine whether coping mediated the association between stressful life events and symptoms of anxiety and depression. Each dimension of stressful life events showed significant correlation with anxiety, depression and coping (all P<0.001). In the model to analyze mediate effects, all standardized coefficients (β) were significant (all P<0.01), indicating marked mediator effects. Furthermore, negative coping might account for more mediate effects than positive coping on this relationship. Coping partially mediated the relationship between stressful life events and mental health during adolescence. This study highlighted an important public health priority for preventive interventions targeting stress-related psychopathology, and for further promoting adolescents' mental health.

    Prochlorococcus and Synechococcus, which numerically dominate vast oceanic areas, are the two most abundant oxygenic phototrophs on Earth. Although they require solar energy for photosynthesis, excess light and associated high UV radiations can induce high levels of oxidative stress that may have deleterious effects on their growth and productivity. Here, we compared the photophysiologies of the model strains Prochlorococcus marinus PCC 9511 and Synechococcus sp. WH7803 grown under a bell-shaped light/dark cycle of high visible light supplemented or not with UV. Prochlorococcus exhibited a higher sensitivity to photoinactivation than Synechococcus under both conditions, as shown by a larger drop of photosystem II (PSII) quantum yield at noon and different diel patterns of the D1 protein pool. In the presence of UV, the PSII repair rate was significantly depressed at noon in Prochlorococcus compared to Synechococcus. Additionally, Prochlorococcus was more sensitive than Synechococcus to oxidative stress, as shown by the different degrees of PSII photoinactivation after addition of hydrogen peroxide. A transcriptional analysis also revealed dramatic discrepancies between the two organisms in the diel expression patterns of several genes involved notably in the biosynthesis and/or repair of photosystems, light-harvesting complexes, CO(2) fixation as well as protection mechanisms against light, UV, and oxidative stress, which likely translate profound differences in their light-controlled regulation. Altogether our results suggest that while Synechococcus has developed efficient ways to cope with light and UV stress, Prochlorococcus cells seemingly survive stressful hours of the day by launching a minimal set of protection mechanisms and by temporarily bringing down several key metabolic processes. This study provides unprecedented insights into understanding the distinct depth distributions and dynamics of these two picocyanobacteria in the field.

    Cognitive behavioral therapies decrease pain and improve mood and function in people with osteoarthritis. This study assessed the effects of coping strategies on the central processing of knee pain in people with osteoarthritis of the knees. Mechanical pressure was applied to exacerbate knee pain in 28 people with osteoarthritis of the knee. Reports of pain intensity and functional magnetic resonance imaging measures of pain-related brain activity were recorded with and without the concurrent use of pain coping skills. Coping skills led to a significant reduction in pain report (Coping = 2.64 ± 0.17, Not Coping = 3.28 ± 0.15, P < 0.001). These strategies were associated with increased activation in pain modulatory regions of the brain (medial prefrontal and rostral anterior cingulate cortices, Pcorrected < 0.05) and decreased pain-related activation in regions that process noxious input (midcingulate cortex, supplementary motor area, secondary somatosensory cortex, and anterior parietal lobule, Pcorrected < 0.05). The magnitude of the decrease in pain report during the use of pain coping strategies was found to be proportional to the decrease in pain-related activation in brain regions that code the aversive/emotional dimension of pain (anterior insula, inferior frontal gyrus, orbitofrontal cortex, Pcorrected < 0.05) but did not differ between groups with and without training in coping skills. However, training in coping skills reduced the extent to which brain responses to noxious input were influenced by anxiety. The results of this study support previous reports of pain modulation by cognitive pain coping strategies and contribute to the current understanding of how analgesia associated with the use of pain coping strategies is represented in the brain.

    Temperature profoundly influences physiological responses in animals, primarily due to the effects on biochemical reaction rates. Since physiological responses are often exemplified by their rate dependency (e.g., rate of blood flow, rate of metabolism, rate of heat production, and rate of ion pumping), the study of temperature adaptations has a long history in comparative and evolutionary physiology. Animals may either defend a fairly constant temperature by recruiting biochemical mechanisms of heat production and utilizing physiological responses geared toward modifying heat loss and heat gain from the environment, or utilize biochemical modifications to allow for physiological adjustments to temperature. Biochemical adaptations to temperature involve alterations in protein structure that compromise the effects of increased temperatures on improving catalytic enzyme function with the detrimental influences of higher temperature on protein stability. Temperature has acted to shape the responses of animal proteins in manners that generally preserve turnover rates at animals' normal, or optimal, body temperatures. Physiological responses to cold and warmth differ depending on whether animals maintain elevated body temperatures (endothermic) or exhibit minimal internal heat production (ectothermic). In both cases, however, these mechanisms involve regulated neural and hormonal over heat flow to the body or heat flow within the body. Examples of biochemical responses to temperature in endotherms involve metabolic uncoupling mechanisms that decrease metabolic efficiency with the outcome of producing heat, whereas ectothermic adaptations to temperature are best exemplified by the numerous mechanisms that allow for the tolerance or avoidance of ice crystal formation at temperatures below 0°C. 2012 American Physiological Society.

    Religion is a form of coping that helps individuals to deal with a wide variety of difficult life situations. But most of the research in this field has been in acute patients of schizophrenia. Also, most of the research on religion and schizophrenia has focused on religion and spirituality as coping mechanisms, and research evaluating the relationship between spirituality/religiousness and repertoire of other coping skills is sparse. Our objective was to evaluate the association between spirituality, religiousness and coping skills in patients with schizophrenia in remission. Hence, a total of 48 consecutive patients with schizophrenia were assessed on Positive and Negative Syndrome Scale (PANSS), Personal and Social Performance Scale (PSP), WHO Quality of Life-Spirituality, Religiousness and Personal Belief scale (WHOQOL-SRPB) and Ways of Coping Checklist - Revised (WCC). Findings were described as patients who used more religiosity and spirituality as measured with WHO-SRPB domain score were better in their managing their stress as they used all the adaptive strategies like planful problem solving, positive reappraisal, distancing, self-controlling, seeking social support rather than maladaptive skills like confrontive coping and escape avoidance. A sound spiritual, religious, or personal belief system positively affects active and adaptive coping skills in patients with schizophrenia during remission, thus helping the individual to cope with illness related stressors.

    The purpose of this study was to compare the marginal and internal adaptation of cobalt-chromium (Co-Cr) copings fabricated from conventional wax pattern, three-dimensional (3D)-printed resin pattern, and laser sintering technique. A total of thirty copings were made, out of which ten copings were made from 3D-printed resin pattern (Group A), ten from inlay wax pattern (Group B), and ten copings were obtained from direct metal laser sintering (DMLS) technique (Group C). All the thirty samples were seated on their respective dies and sectioned carefully using a laser jet cutter and were evaluated for marginal and internal gaps at the predetermined areas using a stereomicroscope. The values were then analyzed using one-way ANOVA test and post hoc Bonferroni test. One-way ANOVA showed lowest mean marginal discrepancy for DMLS and highest value for copings fabricated from inlay wax. The values for internal discrepancy were highest for DMLS (169.38) and lowest for 3D-printed resin pattern fabricated copings (133.87). Post hoc Bonferroni test for both marginal and internal discrepancies showed nonsignificant difference when Group A was compared to Group B ( P > 0.05) and significant when Group A was compared with Group C ( P < 0.05). Group B showed significant difference ( P < 0.05) when compared with Group C. Marginal and internal discrepancies of all the three casting techniques were within clinically acceptable values. Marginal fit of DMLS was superior as compared to other two techniques, whereas when internal fit was evaluated, conventional technique showed the best internal fit.

  14. Drought Adaptation Mechanisms Should Guide Experimental Design.

    PubMed

    Gilbert, Matthew E; Medina, Viviana

    2016-08-01

    The mechanism, or hypothesis, of how a plant might be adapted to drought should strongly influence experimental design. For instance, an experiment testing for water conservation should be distinct from a damage-tolerance evaluation. We define here four new, general mechanisms for plant adaptation to drought such that experiments can be more easily designed based upon the definitions. A series of experimental methods are suggested together with appropriate physiological measurements related to the drought adaptation mechanisms. The suggestion is made that the experimental manipulation should match the rate, length, and severity of soil water deficit (SWD) necessary to test the hypothesized type of drought adaptation mechanism.

  16. Evolution of adaptation mechanisms: Adaptation energy, stress, and oscillating death.

    Gorban, Alexander N; Tyukina, Tatiana A; Smirnova, Elena V; Pokidysheva, Lyudmila I

    2016-09-21

    In 1938, Selye proposed the notion of adaptation energy and published 'Experimental evidence supporting the conception of adaptation energy.' Adaptation of an animal to different factors appears as the spending of one resource. Adaptation energy is a hypothetical extensive quantity spent for adaptation. This term causes much debate when one takes it literally, as a physical quantity, i.e. a sort of energy. The controversial points of view impede the systematic use of the notion of adaptation energy despite experimental evidence. Nevertheless, the response to many harmful factors often has general non-specific form and we suggest that the mechanisms of physiological adaptation admit a very general and nonspecific description. We aim to demonstrate that Selye׳s adaptation energy is the cornerstone of the top-down approach to modelling of non-specific adaptation processes. We analyze Selye׳s axioms of adaptation energy together with Goldstone׳s modifications and propose a series of models for interpretation of these axioms. Adaptation energy is considered as an internal coordinate on the 'dominant path' in the model of adaptation. The phenomena of 'oscillating death' and 'oscillating remission' are predicted on the base of the dynamical models of adaptation. Natural selection plays a key role in the evolution of mechanisms of physiological adaptation. We use the fitness optimization approach to study of the distribution of resources for neutralization of harmful factors, during adaptation to a multifactor environment, and analyze the optimal strategies for different systems of factors.

    1995-01-01

    Using a definition based on Bowlby and Pörn, an effort is made to interpret adaptedness and coping in 87 dysphagic students (corresponding to a prevalence of dysphagia in 9% of the boys and 12% of the girls) found in a screening study utilizing a questionnaire. Coping patterns and methods of adaptation were explored in a telephone interview with dysphagic students. Those who stated that their dysphagia influenced their daily living were classified as subjectively maladapted (S-maladapted; n = 9). Compared with the S-adapted students, the S-maladapted students reported more defects in ability to eat, more inappropriate beliefs about the causes and management of dysphagia, and greater desires regarding eating than S-adapted students (p < 0.05). The environmental conditions more often impaired the eating ability in S-maladapted students (p < 0.05). Anxiety at mealtime was reported more frequently than in S-adapted students (p < 0.05). Every second S-maladapted student had reduced self-esteem because of dysphagia (p < 0.05). The S-maladapted students had talked about their dysphagia with parents and/or friends and visited a school physician because of dysphagia more often than S-adapted students (p < 0.05). Two of 9 students felt confirmed by the physician and experienced help. There was concordance between the students' own beliefs regarding the causes of dysphagia and corresponding coping strategy.

  18. Mechanisms of Adaptation to Nitrosative Stress in Bacillus subtilis▿ †

    2007-01-01

    Bacteria use a number of mechanisms for coping with the toxic effects exerted by nitric oxide (NO) and its derivatives. Here we show that the flavohemoglobin encoded by the hmp gene has a vital role in an adaptive response to protect the soil bacterium Bacillus subtilis from nitrosative stress. We further show that nitrosative stress induced by the nitrosonium cation donor sodium nitroprusside (SNP) leads to deactivation of the transcriptional repressor NsrR, resulting in derepression of hmp. Nitrosative stress induces the sigma B-controlled general stress regulon. However, a sigB null mutant did not show increased sensitivity to SNP, suggesting that the sigma B-dependent stress proteins are involved in a nonspecific protection against stress whereas the Hmp flavohemoglobin plays a central role in detoxification. Mutations in the yjbIH operon, which encodes a truncated hemoglobin (YjbI) and a predicted 34-kDa cytosolic protein of unknown function (YjbH), rendered B. subtilis hypersensitive to SNP, suggesting roles in nitrosative stress management.

    Families who foster offer essential care for children and youth when their own parents are unable to provide for their safety and well-being. Foster caregivers face many challenges including increased workload, emotional distress, and the difficulties associated with health and mental health problems that are more common in children in foster care. Despite these stressors, many families are able to sustain fostering while maintaining or enhancing functioning of their unit. This qualitative study applied an adaptational process model of family resilience that emerged in previous studies to examine narratives of persistent, long-term, and multiple fostering experiences. Data corroborated previous research in two ways. Family resilience was again described as a transactional process of coping and adaptation that evolves over time. This process was cultivated through the activation of 10 family strengths that are important in different ways, during varied phases. © 2016 Family Process Institute.

    Clergy members suffering from burnout face both personal and professional complications. This study assessed occupational burnout and stress coping mechanisms among ministers affiliated with the Assemblies of God, a denomination that has received little attention in previous burnout-related studies. A cross-sectional design was employed using two instruments with acceptable psychometric properties. Approximately 65 % of those surveyed were either suffering from burnout or on the verge of burnout. Statistical differences in coping mechanism use were found between those who were and were not experiencing some level of burnout. The results of this study add to the existing understanding of occupational burnout among clergy members and ways in which burnout may be alleviated.

    To explore 1) if perfectionism, perceived distress/coping, and cognitive emotion regulation (CER) are associated with and predictive of negative/positive affect (NA/PA); and 2) if CER and perceived distress/coping are associated with perfectionism and if they mediate the perfectionism-NA/PA associations. There is a distinction between maladaptive and adaptive perfectionism in its association with NA/PA. CER and perceived distress/coping may mediate the maladaptive/adaptive perfectionism and NA/PA associations. 344 students (68.4% girls) completed the Hewitt & Flett and the Frost Multidimensional Perfectionism Scales, the Composite Multidimensional Perfectionism Scale, the Profile of Mood States, the Perceived Stress Scale, and the Cognitive Emotion Regulation Questionnaire. NA predictors were maladaptive/adaptive perfectionism, maladaptive CER and perceived distress (positively), positive reappraisal and planning, and perceived coping (negatively). PA predictors were maladaptive/adaptive perfectionism and perceived distress (negatively), positive reappraisal and planning, positive refocusing and perceived coping (positively). The association between maladaptive perfectionism and NA was mediated by maladaptive CER/low adaptive CER, perceived distress/low coping. Maladaptive perfectionism and low PA association was mediated by perceived distress. High PA was determined by low maladaptive perfectionism and this association was mediated by adaptive REC and coping. Adaptive perfectionism and NA association was mediated by maladaptive CER and perceived distress. CER and perceived distress/coping are associated and mediate the perfectionism-NA/PA associations.

    Previous research has documented disparities in smoking cessation between African Americans and Caucasians. Many low-income African American smokers face a range of circumstances that may inhibit effective coping during quit attempts, yet previous research has not considered factors that influence coping in this population. This study examined (a) affect (positive and negative) and (b) perceived social support in association with coping strategies. The baseline assessment of African American smokers (N = 168) enrolled in a randomized controlled trial included the Positive and Negative Affect Schedule, the Multidimensional Scale of Perceived Social Support, and the Brief COPE. A factor analysis of the Brief COPE resulted in two factors, adaptive and maladaptive strategies. Participants were mostly single (64%), women (61%), with ≥12 years of education (68%), and low-income. They were middle aged (M = 46.1, SD = 8.7), smoked 21.8 (SD = 13.3) cigarettes/day for 24.3 (SD = 11) years, and were moderately nicotine dependent. Results demonstrated that adaptive coping was positively correlated with positive affect and social support. Maladaptive coping was positively correlated with negative affect, and inversely related to positive affect and social support. Multivariate analyses revealed that positive affect and social support were independently associated with adaptive coping strategies. In contrast, maladaptive coping was independently associated with negative affect, but not social support. Interventions that harness positive resources, such as social support and positive mood, may facilitate adaptive coping. Also, addressing negative affect among low-income African American smokers may be important to reduce maladaptive coping strategies. © 2013 Elsevier Ltd. All rights reserved.

    People with vision loss from diabetic retinopathy (DR) and diabetic macular edema (DME) use problem-focused and emotion-regulation strategies that may influence their short- and longer-term adaptation and psychological outcomes. Our findings can assist the development of models of adjustment to DR/DME-related vision loss and treatments focused on adaptation. To qualitatively determine the coping strategies used by participants with vision loss resulting from DR/DME. Fifty-seven participants with DR/DME engaged in one of eight focus groups or one of 18 semistructured interviews. Participants were mostly older than 55 years (mean, 58.7 years) and male (68%) and had type 2 diabetes (74%; median duration, 17 years). Almost 50% had proliferative DR, 95% had undergone laser treatment, and 42% had DME; 68%, 14% and 14% had none, mild (<0.3 logarithm of the minimum angle of resolution ≤ 0.48), and moderate-severe vision impairment (>0.48 logarithm of the minimum angle of resolution) in the better eye. Focus groups/interviews were transcribed verbatim and iteratively analyzed using the constant comparative method. Qualitative software NVivo 2008 was used to sort/store the data. Our top-down and bottom-up approach to conceptualize the data was informed by the Transactional Model of Stress and Coping. Coping efforts were mostly problem focused (64%) with seven subthemes: problem solving, passive coping, changing activities to suit a new ability level, active coping, rehearsing alternative outcomes, maintaining independence, and information seeking. Emotion-regulation strategies were distraction, acceptance, alternative adaptive thinking, avoidance, expressing emotions, denial, and changing emotions. Meaning-based coping strategies included mindfulness and engaging in meaningful activities. Themes relating to adaptation and moderators to coping (e.g., dispositional optimism) are outlined. Participants described a variety of ways to cope. Some strategies are likely to improve

    Pollination by sexual deception is arguably one of the most unusual liaisons linking plants and insects, and perhaps the most illustrative example of extreme floral specialization in angiosperms. While considerable progress has been made in understanding the floral traits involved in sexual deception, less is known about how this remarkable mimicry system might have arisen, the role of pre-adaptations in promoting its evolution and its extent as a pollination mechanism outside the few groups of plants (primarily orchids) where it has been described to date. In the Euro-Mediterranean region, pollination by sexual deception is traditionally considered to be the hallmark of the orchid genus Ophrys. Here, we introduce two new cases outside of Ophrys, in plant groups dominated by generalized, shelter-mimicking species. On the basis of phylogenetic reconstructions of ancestral pollination strategies, we provide evidence for independent and bidirectional evolutionary transitions between generalized (shelter mimicry) and specialized (sexual deception) pollination strategies in three groups of flowering plants, and suggest that pseudocopulation has evolved from pre-adaptations (floral colours, shapes and odour bouquets) that selectively attract male pollinators through shelter mimicry. These findings, along with comparative analyses of floral traits (colours and scents), shed light on particular phenotypic changes that might have fuelled the parallel evolution of these extraordinary pollination strategies. Collectively, our results provide the first substantive insights into how pollination sexual deception might have evolved in the Euro-Mediterranean region, and demonstrate that even the most extreme cases of pollinator specialization can reverse to more generalized interactions, breaking 'Cope's rule of specialization'.

    Individually consistent behavioral and physiological responses to stressful situations (often referred to as coping styles) has been reported in many animal species. Differences in hypothalamic-pituitary axis reactivity characterize individuals, and it has been proposed that the glucocorticoid (gr) and mineralocorticoid (mr) receptors are fundamental in regulating coping styles. We sorted individuals into reactive and proactive coping styles by collapsing behavioral outputs from net restraint and confinement stress tests in a principal component analysis. We then analyzed plasma cortisol levels, serotonin neurochemistry and the relative mRNA expression of gr1 and mr in stressed individuals per coping style. Proactive fish were characterized as having a lower serotonergic activity and being more active under stress. In addition, proactive fish had higher hypothalamic gr1 and mr abundance and a higher mr/gr1 ratio, compared to reactive fish. We found no significant differences in cortisol or telencephalic mRNA, gr1 and mr expression, or their ratio. Brain MR and GR have been proven to have an important role in the appraisal, coping and adaptation to stressful stimuli, so that a higher expression of these receptors in proactive fish suggests increased tolerance and performance under stress, compared to reactive individuals. We present evidence of a conserved neuroendocrine mechanism associated with coping styles in a fish species which is ecologically very diverse and considered to be the most cold-adapted fish in freshwater. We propose that this may be a first step into exploiting this model in order to better understand climate-change related effects in sub populations and ecophenotypes. Copyright © 2017 Elsevier Inc.

    Background and aims Few studies have examined the stigma of problem gambling and little is known about those who internalize this prejudice as damaging self-stigma. This paper aimed to identify psychological factors, sociodemographic characteristics, and coping mechanisms associated with the self-stigma of problem gambling. Methods An online survey was conducted on 177 Australian adults with a current gambling problem to measure self-stigma, self-esteem, social anxiety, self-consciousness, psychological distress, symptom severity, most problematic gambling form, stigma coping mechanisms, and sociodemographic characteristics. Results All variables significantly correlated with self-stigma were considered for inclusion in a regression model. A multivariate linear regression indicated that higher levels of self-stigma were associated with: being female, being older, lower self-esteem, higher problem gambling severity score, and greater use of secrecy (standardized coefficients: 0.16, 0.14, -0.33, 0.23, and 0.15, respectively). Strongest predictors in the model were self-esteem, followed by symptom severity score. Together, predictors in the model accounted for 38.9% of the variance in self-stigma. Discussion and conclusions These results suggest that the self-stigma of problem gambling may be driven by similar mechanisms as the self-stigma of other mental health disorders, and impact similarly on self-esteem and coping. Thus, self-stigma reduction initiatives used for other mental health conditions may be effective for problem gambling. In contrast, however, the self-stigma of problem gambling increased with female gender and older age, which are associated with gaming machine problems. This group should, therefore, be a target population for efforts to reduce or better cope with the self-stigma of problem gambling.

    Style Questionnaire-40 translated into French, but not validated, assessed defenses and defense style. Descriptive, comparative and correlational analysis was carried out using Statistica software - version 10. The alcohol-dependent people preferentially use emotion focused coping blame and less the problem focused coping humor. The highest immature defense is acting out. Correlational analyses confirm the presence of some significant relationships between defense style and some coping strategies. Thus, the mature style is the only defense style, which is linked with the problem focused strategy humor, and another one coping called distraction. Some singular relationships were found with these two dimensions of coping. Alcohol and drug disengagement show particularly strong relationships with immature defenses such as projection and somatization. Another singular result is indicated by a negative relationship between immature defenses autistic fantasy with the strategy expression of feelings. This study found a significant number of relationships between defensive styles, defenses and coping strategies. This research also highlights the value of an integrative approach of defense mechanisms for the analysis of defensive functioning of people with alcohol dependence. Indeed, the relationships between these elements are consistent and allow understanding the defensive operation as a whole to promote a new adapted means of support.

  13. Water management to cope with and adapt to climate variability and change.

    2009-04-01

    In many parts of the world, variability in climatic conditions is already resulting in major impacts. These impacts are wide ranging and the link to water management problems is obvious and profound. The know-how and the available information undoubtedly indicate that climate change will lead to an intensification of the global hydrological cycle and can have major impacts on regional water resources, affecting both ground and surface water supply for sectorial water uses and, in particular, the irrigation field imposing notable negative effects on food security and poverty alleviation programs in most arid and semi-arid developing countries. At the United Nations Millennium Summit, in September 2000, world leaders adopted the Millennium Development Declaration. From this declaration, the IWRM was recognised as the key concept the water sector should be using for water related development and measures and, hence, for achieving the water related MDG's. However, the potential impacts of climate change and increasing climate variability are not sufficiently addressed in the IWRM plans. Indeed, only a very limited IWRM national plans have been prepared, coping with climate variability and changes. This is mainly due to the lack of operational instruments to deal with climate change and climate variability issues. This is particularly true in developing countries where the financial, human and ecological impacts are potentially greatest and where water resources may be already highly stressed, but the capacity to cope and adapt is weakest. Climate change has now brought realities including mainly rising temperatures and increasing frequency of floods and droughts that present new challenges to be addressed by the IWRM practice. There are already several regional and international initiatives underway that focus on various aspects of water resources management those to be linked with climate changes and vulnerability issues. This is the way where the water resources

    Using a longitudinal design, the authors examined coping and cognitive functioning in the development of depression in individuals with multiple sclerosis (MS). Coping style was evaluated in 2 conceptually distinct roles: as moderator and mediator of the impact of cognitive dysfunction on depression. Using indices derived from the COPE (C. S. Carver, M. F. Scheier, & J. K. Weintraub, 1989), the authors operationalized coping in 3 ways-as active, avoidant, and an index accounting for relative levels of both. Coping both moderated and partially mediated the relationship between cognitive dysfunction and depression. Moderation results suggest that the relationship between cognitive dysfunction and depression is dependent on coping style-adaptive coping protects individuals from experiencing depression related to their cognitive deficits; however, when individuals use maladaptive coping, cognitive dysfunction puts them at risk for depression. Mediational results suggest that cognitive dysfunction leads to depression partially due to cognitive dysfunction's effects on coping. That is, cognitive deficits may impair individuals' ability to use adaptive coping strategies, leaving them more likely to use maladaptive strategies. Clinical and theoretical implications of these findings are discussed.

    We examined the mediating role of behavioral coping strategies in the association between work-family conflict and psychological distress. In particular, we examined the two directions of work-family conflict, namely, work interference into family and family interference into work. Furthermore, two coping styles in this study were adaptive and maladaptive coping strategies. This cross-sectional study was conducted among 429 Malaysian working women using self-reported data. The results of mediational analysis in the present study showed that adaptive coping strategy does not significantly mediate the effect of work-family conflict on psychological distress. However, maladaptive coping strategies significantly mediate the effect of work-family conflict on psychological distress. These results show that adaptive coping strategies, which aimed to improve the stressful situation, are not effective in managing stressor such as work-family conflict. We found that experiencing interrole conflict steers employees toward frequent use of maladaptive coping strategies which in turn lead to psychological distress. Interventions targeted at improvement of coping skills which are according to individual's needs and expectation may help working women to balance work and family demands. The important issue is to keep in mind that effective coping strategies are to control the situations not to eliminate work-family conflict.

    Incidence of depressive symptoms and lack of sufficient adaptive coping skills in adolescents. A randomized controlled study to test the effectiveness of a group-administered, cognitive-behavioral interventions method, TKC, on rural adolescents (N = 89). Outcomes were measured by changes in the scores on an Adolescent Depression Scale and the Coping Response Inventory pre/post intervention, at 6 and at 12 months. Results indicated improvement in depressive symptomatology and certain coping skills. Students in the intervention reported a higher use of cognitive problem-solving coping strategies. The role of a psychiatric nurse in the school system providing short-term psychoeducation interventions is a practical and effective mental health practice.

    Are effects of background contrast on color appearance and sensitivity controlled by the same mechanism of adaptation? We examined the effects of background color contrast on color appearance and on color-difference sensitivity under well-matched conditions. We linked the data using Fechner's hypothesis that the rate of apparent stimulus change is proportional to sensitivity and examined a family of parametric models of adaptation. Our results show that both appearance and discrimination are consistent with the same mechanism of adaptation.

    This study investigated sexual drive and satisfaction of Chinese gynecologic cancer survivors. It also examined the extent to which personal mastery, adaptive coping, and perceived spousal support would exert direct and/or indirect influences on sexual outcomes. The cancer survivor group included 134 Chinese women who had received treatment for gynecologic cancer, while the healthy control group included 105 Chinese women who did not have a known history or current diagnosis of cancer. Compared to healthy women, cancer survivors reported lower levels of sexual drive and sexual satisfaction. Among sexually active participants, cancer survivors relative to healthy women engaged in less masturbation, less kissing and caressing, and less sexual fantasy in the past month. Hierarchical multiple regression analyses showed that mastery and spousal support, but not adaptive coping, had a direct influence on sexual outcomes in cancer survivors. Contrary to moderation hypotheses, the three psychological factors did not interact with each other to influence sexual drive and satisfaction. Mediation analyses showed that spousal support fully mediated the influence of mastery on sexual satisfaction. Routine assessment of sexual functioning prior to and following treatment of gynecologic cancer is suggested. Sexual rehabilitation should also aim to enhance personal mastery and spousal support.

    This ex post facto descriptive correlational design study of widows during their second year of bereavement utilizes Roy's adaptation model as a guiding framework. Contextual stimuli (social support, social network, income/education, spiritual beliefs) were related to the cognator function (coping process), which was related to adaptation outcome (grief response). Significant moderate positive relationships were found between social support and coping process, and between social network and coping process. A significant relationship was also found between coping process and grief response. The path model accounted for 18% explained variance.

    The purpose of this pilot randomized controlled trial was to investigate the acceptability and efficacy of the Acquiring Career, Coping, Executive control, Social Skills (ACCESS) Program, a group intervention tailored for young adults with autism spectrum disorder (ASD) to enhance critical skills and beliefs that promote adult functioning, including social and adaptive skills, self-determination skills, and coping self-efficacy. Forty-four adults with ASD (ages 18-38; 13 females) and their caregivers were randomly assigned to treatment or waitlist control. Compared to controls, adults in treatment significantly improved in adaptive and self-determination skills, per caregiver report, and self-reported greater belief in their ability to access social support to cope with stressors. Results provide evidence for the acceptability and efficacy of the ACCESS Program.

    Background The aim of the present study was to explore the prospective relationship between anxiety symptoms and coping strategies during late pregnancy and early postpartum. Methods Participants completed the Hospital Anxiety Depression-Anxiety subscale and Carver’s Brief COPE at two time points, namely during the last trimester of pregnancy (N = 400) and at two months postpartum (N = 158). Results Antenatally, 18.8% of pregnant women presented severe anxiety symptoms while 20.2% of women presented severe anxiety symptoms after birth. Carver's proposed coping styles allowed to significantly distinguish between anxious and non anxious women during these two periods. Anxious women used significantly more inappropriate coping and less adaptive coping responses, such as self-blame and denial of reality, which remained associated with anxiety in the perinatal period. Our results also indicated a decrease in adaptive coping in women without anxiety after birth (e.g. acceptance, positive reframing). Conclusion Our findings confirm that antenatal and postnatal anxiety symptoms occur frequently and that inappropriate and/or non functional coping may account for persisting anxiety after childbirth. Limitations: Data were based on self-reports and participating women were predominantly primiparous. A high drop-out rate at two months postpartum must also be acknowledged. PMID:24330429

    Prior work has identified alterations in activity of the hypothalamic-pituitary-adrenal axis as a potential mechanism underlying stress-induced emotional health problems, which disproportionately impact girls beginning in mid-adolescence. How adolescent girls differ from one another in dispositional coping tendencies and shift specific coping strategies in response to varying stressors have been theorized as important predictors of their adaptation, health, and well-being during this dynamic period of development. The goal of this study was to examine whether individual and day-to-day (within-person) differences in adolescent girls' coping responses are associated with daily patterns of hypothalamic-pituitary-adrenal axis activity, indexed by cortisol. Participants were 122 early adolescent girls (M age  = 12.39) who provided three saliva samples per day for 3 days and completed daily coping reports, as well as a standard coping survey. Participants and primary caregivers also completed objective life stress interviews. On average, girls who were more likely to respond to interpersonal stress with voluntary engagement (active) coping exhibited generally adaptive daily physiological regulation-steeper diurnal cortisol slopes, lower total diurnal cortisol output, and lower cortisol awakening responses. Chronic interpersonal stress level significantly moderated these associations in different ways for two distinct components of the diurnal pattern-the slope and cortisol awakening responses. Regarding within-person differences, using active coping more than usual was associated with higher waking cortisol the following morning, which may help to prepare adolescent girls for perceived daily demands. These findings highlight the interactive influence of stress and coping in the prediction of daily hypothalamic-pituitary-adrenal axis activity and support the stress-buffering role of active coping for adolescent girls.

    2013-07-01

    Pregnancy termination for fetal abnormality (TFA) can have significant psychological consequences. Most previous research has been focused on measuring the psychological outcomes of TFA, and little is known about the coping strategies involved. In this article, we report on women's coping strategies used during and after the procedure. Our account is based on experiences of 27 women who completed an online survey. We analyzed the data using interpretative phenomenological analysis. Coping comprised four structures, consistent across time points: support, acceptance, avoidance, and meaning attribution. Women mostly used adaptive coping strategies but reported inadequacies in aftercare, which challenged their resources. The study's findings indicate the need to provide sensitive, nondirective care rooted in the acknowledgment of the unique nature of TFA. Enabling women to reciprocate for emotional support, promoting adaptive coping strategies, highlighting the potential value of spending time with the baby, and providing long-term support (including during subsequent pregnancies) might promote psychological adjustment to TFA.

    Ecosystem services are typically valued for their immediate material or cultural benefits to human wellbeing, supported by regulating and supporting services. Under climate change, with more frequent stresses and novel shocks, 'climate adaptation services', are defined as the benefits to people from increased social ability to respond to change, provided by the capability of ecosystems to moderate and adapt to climate change and variability. They broaden the ecosystem services framework to assist decision makers in planning for an uncertain future with new choices and options. We present a generic framework for operationalising the adaptation services concept. Four steps guide the identification of intrinsic ecological mechanisms that facilitate the maintenance and emergence of ecosystem services during periods of change, and so materialise as adaptation services. We applied this framework for four contrasted Australian ecosystems. Comparative analyses enabled by the operational framework suggest that adaptation services that emerge during trajectories of ecological change are supported by common mechanisms: vegetation structural diversity, the role of keystone species or functional groups, response diversity and landscape connectivity, which underpin the persistence of function and the reassembly of ecological communities under severe climate change and variability. Such understanding should guide ecosystem management towards adaptation planning. © 2014 John Wiley & Sons Ltd.

    The prevalence of burnout, psychological morbidity and the use of coping mechanisms among palliative care practitioners in Singapore have not been studied. We aimed to study the prevalence of burnout and psychological morbidity among palliative care practitioners in Singapore and its associations with demographic and workplace factors as well as the use of coping mechanisms. This was a multi-centre, cross-sectional study of all the palliative care providers within the public healthcare sector in Singapore. The study was conducted in hospital palliative care services, home hospice and inpatient hospices in Singapore. The participants were doctors, nurses and social workers. The prevalence of burnout among respondents in our study was 91 of 273 (33.3%) and psychological morbidity was 77 (28.2%). Working >60 h per week was significantly associated with burnout (odds ratio: 9.02, 95% confidence interval: 2.3-35.8, p = 0.002) and psychological morbidity (odds ratio: 7.21, 95% confidence interval: 1.8-28.8, p = 0.005). Home hospice care practitioners (41.5%) were more at risk of developing psychological morbidity compared to hospital-based palliative care (17.5%) or hospice inpatient care (26.0%) (p = 0.007). Coping mechanisms like physical well-being, clinical variety, setting boundaries, transcendental (meditation and quiet reflection), passion for one's work, realistic expectations, remembering patients and organisational activities were associated with less burnout. Our results reveal that burnout and psychological morbidity are significant in the palliative care community and demonstrate a need to look at managing long working hours and promoting the use of coping mechanisms to reduce burnout and psychological morbidity. © The Author(s) 2015.

Correlational and cross-sectorial study with probabilistic sampling. A sample of 208 nursing professionals from University Hospital of Fuenlabrada (Madrid) took part in the study. This sample consisted of nurses (n = 133), nursing assistants (n = 61), and midwives (n = 14), of whom 94 worked in special units and 114 worked in wards. 10-Item CD-RISC (resilience), Brief-Cope (coping strategies), PWB scales (PWB dimensions), and sociodemographic variables. No differences were found in any assessed psychological variables as regards hospital service worked in. A structural model was found where resilience was a precursor factor of coping that determined the PWB of the nurses. Resilience favoured strategies related to engagement coping with stressful situations (β = 0.56) that contributed to PWB (β = 0.43) (these relationships were inverted in the case of disengagement coping). Resilience is an inherent feature in nursing staff whether they work in special units or wards. Coping strategies focused on engagement (or adaptive) with the stressful situation determined nursing PWB (primarily self-acceptance and environment mastery dimensions). Resilience and coping strategies more adaptives constitute two personal resources that determine PWB. Copyright © 2014 Elsevier España, S.L.U. All rights reserved.

    This study explored how coping with war-related traumatic events in Sierra Leone impacted mental health outcomes among 529 youth (aged 10-17 at baseline; 25% female) using longitudinal data from three time points (Time 1 in 2002, Time 2 in 2004, and Time 3 in 2008). We examined two types of coping items (approach and avoidance); used multiple regression models to test their relations with long-term mental health outcomes (internalizing behaviors, externalizing behaviors, adaptive/prosocial behaviors, and posttraumatic stress symptoms); and used mediation analyses to test whether coping explained the relation between previous war exposures (being raped, death of parent(s), or killing/injuring someone during the war) and those outcomes. We found that avoidance coping items were associated with lower internalizing and posttraumatic stress behaviors at Time 3, and provided some evidence of mediating the relation between death of parent(s) during the war and the two outcomes mentioned above. Approach coping was associated with higher Time 3 adaptive/prosocial behaviors, whereas avoidance coping was associated with lower Time 3 adaptive/prosocial behaviors. Avoidance coping may be a protective factor against mental illness, whereas approach coping may be a promotive factor for adaptive/prosocial behaviors in war-affected societies. This study has important implications for designing and implementing mental health interventions for youth in postconflict settings.

    We hypothesized that the effects of personality (self-esteem, control, and optimism) on postabortion adaptation (distress, well-being, and decision satisfaction) would be fully mediated by preabortion cognitive appraisals (stress appraisals and self-efficacy appraisals) and postabortion coping. We further proposed that the effects of preabortion appraisals on adaptation would be fully mediated by postabortion coping. Results of a longitudinal study of 527 women who had first-trimester abortions supported our hypotheses. Women with more resilient personalities appraised their abortion as less stressful and had higher self-efficacy for coping with the abortion. More positive appraisals predicted greater acceptance/reframing coping and lesser avoidance/denial, venting, support seeking, and religious coping. Acceptance-reframing predicted better adjustment on all measures, whereas avoidance-denial and venting related to poorer adjustment on all measures. Greater support seeking was associated with reduced distress, and greater religious coping was associated with less decision satisfaction.

    The current study explored the impact of varying the order of message components on coping with breast cancer information. In a 2 x 2 x 2 factorial design, threat information, coping information and order of information were manipulated. College students read persuasive essays that varied in emphasis on threat of developing breast cancer and effectiveness of breast self-examination (BSE) in averting the threat of cancer. Participants who read the high-threat message reported higher intentions to perform BSE, more rational problem solving and more hopelessness than did those who read a low-threat message. The coping information messages produced a similar pattern of results. In addition, those who read the high-coping message reported less fatalism than did participants who read the low-coping message. When threat information was presented first, the high-threat message led to less hopelessness and reliance on religious faith than when the coping information was presented first. These results demonstrate the threatening health information energizes one to act in both adaptive and maladaptive ways, and that coping information decreases the tendency to respond maladaptively to the health threat. They also suggest that the order of presentation of the information may affect the extent to which people respond adaptively.

  20. The dual process model of coping with bereavement: rationale and description.

    PubMed

    Stroebe, M; Schut, H

    1999-01-01

    There are shortcomings in traditional theorizing about effective ways of coping with bereavement, most notably, with respect to the so-called "grief work hypothesis." Criticisms include imprecise definition, failure to represent dynamic processing that is characteristic of grieving, lack of empirical evidence and validation across cultures and historical periods, and a limited focus on intrapersonal processes and on health outcomes. Therefore, a revised model of coping with bereavement, the dual process model, is proposed. This model identifies two types of stressors, loss- and restoration-oriented, and a dynamic, regulatory coping process of oscillation, whereby the grieving individual at times confronts, at other times avoids, the different tasks of grieving. This model proposes that adaptive coping is composed of confrontation--avoidance of loss and restoration stressors. It also argues the need for dosage of grieving, that is, the need to take respite from dealing with either of these stressors, as an integral part of adaptive coping. Empirical research to support this conceptualization is discussed, and the model's relevance to the examination of complicated grief, analysis of subgroup phenomena, as well as interpersonal coping processes, is described.

    While cannabis has been recognized as the most illicit drug use in the world, few studies focusing on cannabis self-change and cannabis relapse or abstinence in adult non-treatment samples have been conducted. The first aim of this study was to understand cannabis self-change motives, coping and adaptation strategies and evaluating perceived benefits from cannabis cessation. The second aim was to compare, in a convenience sample of non-treatment-seeking adult cannabis smokers, motivations to quit smoking cannabis, coping and adaptive strategies, as well as perceived benefit from cessation between cannabis abstinent and participants who relapse. Sixty-three participants (31 men and 32 women) who attempted to quit cannabis in a non-controlled environment without medical help and were enrolled. They completed the Marijuana Quit Questionnaire (MJQQ), a self-report questionnaire collecting information in three areas: sociodemographic characteristics, cannabis use history (including any associated problems), and participants' characteristics regarding their "most difficult" (self-defined) attempt to quit in a non-controlled environment. For this study the index quit attempt was characterized in two areas: reasons for quitting marijuana, coping strategies used while quitting. Two additional questionnaires were added to the MJQQ; the Brief Cope, and a questionnaire assessing perceived benefit of the cannabis quit attempt. The participants were on average 28.5 years old (±5.1), and started using cannabis on average at 15.8 years (±2.8). Seventy-four percent (n=45) of the participants met the DSM-IV criteria for cannabis dependence before cannabis cessation. T-tests were used to compare abstainers and participants who relapsed after the quit attempt. Realizing that cannabis induces disabling cognitive disorders such as affection of memory, concentration and attention were reported by 71% of the participant as a motivation for quitting cannabis use.

    The present study investigated whether women and men differ with regard to non-religious and religious coping with cancer, here: colon cancer--a question on which only little research has been done so far. 341 patients filled in a questionnaire during inpatient oncological rehabilitation. Statistical analyses showed that women reported higher mental strain than men. They used more bagatellization and wishful thinking, more depressive and less active problem-oriented coping strategies. A higher use of religious coping among women was to a high degree associated with their generally stronger religiosity. Correlations between coping strategies and measures of mental health indicated commonalities and differences. In particular, a positive correlation between active problem-oriented coping and mental health was found for men but not for women. In accordance with women's higher religiosity, the data indicate a stronger correlation between religious coping and adaptation among women than among men. The results suggest that gender differences and religiosity can be relevant in the context of treatment but that their significance must not be overinterpreted. In terms of patient orientation they speak for the necessity to individually assess the need for support, also with regard to the consideration of religiosity in the treatment process.

    The objective of this study was to investigate factors related to family functioning and adaptation in caregivers of individuals with Rett syndrome (RS). A cross-sectional quantitative survey explored the relationships between demographics, parental self-efficacy, coping methods, family functioning and adaptation. A forward-backward, step-wise model selection procedure was used to evaluate variables associated with both family functioning and adaptation. Analyses also explored family functioning as a mediator of the relationship between other variables and adaptation. Bivariate analyses (N=400) revealed that greater parental self-efficacy, a greater proportion of problem-focused coping, and a lesser proportion of emotion-focused coping were associated with more effective family functioning. In addition, these key variables were significantly associated with greater adaptation, as was family functioning, while controlling for confounders. Finally, regression analyses suggest family functioning as a mediator of the relationships between three variables (parental self-efficacy, problem-focused coping, and emotion-focused coping) with adaptation. This study demonstrates the potentially predictive roles of expectations and coping methods and the mediator role of family functioning in adaptation among caregivers of individuals with RS, a chronic developmental disorder. A potential target for intervention is strengthening of caregiver competence in the parenting role to enhance caregiver adaptation. Published by Elsevier Ireland Ltd.

  5. Relationships Among Positive Emotions, Coping, Resilience and Mental Health.

    The broaden-and-build theory of positive emotions suggests that positive emotions can widen the range of potential coping strategies that come to mind and subsequently enhance one's resilience against stress. Studies have shown that high stress, especially chronic levels of stress, strongly contributes to the development of anxiety and depressive symptoms. However, researchers have also found that individuals who possess high levels of resilience are protected from stress and thus report lower levels of anxiety and depressive symptoms. Using a sample of 200 postdoctoral research fellows, the present study examined if (a) positive emotions were associated with greater resilience, (b) coping strategies mediated the link between positive emotions and resilience and (c) resilience moderated the influence of stress on trait anxiety and depressive symptoms. Results support the broaden-and-build theory in that positive emotions may enhance resilience directly as well as indirectly through the mediating role of coping strategies-particularly via adaptive coping. Resilience also moderated the association of stress with trait anxiety and depressive symptoms. Although stress is unavoidable and its influences on anxiety and depressive symptoms are undeniable, the likelihood of postdocs developing anxiety or depressive symptoms may be reduced by implementing programmes designed to increase positive emotions, adaptive coping strategies and resilience.

  6. Biological adaptive control model: a mechanical analogue of multi-factorial bone density adaptation.

    PubMed

    Davidson, Peter L; Milburn, Peter D; Wilson, Barry D

    2004-03-21

    The mechanism of how bone adapts to every day demands needs to be better understood to gain insight into situations in which the musculoskeletal system is perturbed. This paper offers a novel multi-factorial mathematical model of bone density adaptation which combines previous single-factor models in a single adaptation system as a means of gaining this insight. Unique aspects of the model include provision for interaction between factors and an estimation of the relative contribution of each factor. This interacting system is considered analogous to a Newtonian mechanical system and the governing response equation is derived as a linear version of the adaptation process. The transient solution to sudden environmental change is found to be exponential or oscillatory depending on the balance between cellular activation and deactivation frequencies.

  8. Effects of single cortisol administrations on human affect reviewed: Coping with stress through adaptive regulation of automatic cognitive processing.

    PubMed

    Putman, Peter; Roelofs, Karin

    2011-05-01

    The human stress hormone cortisol may facilitate effective coping after psychological stress. In apparent agreement, administration of cortisol has been demonstrated to reduce fear in response to stressors. For anxious patients with phobias or posttraumatic stress disorder this has been ascribed to hypothetical inhibition of retrieval of traumatic memories. However, such stress-protective effects may also work via adaptive regulation of early cognitive processing of threatening information from the environment. This paper selectively reviews the available literature on effects of single cortisol administrations on affect and early cognitive processing of affectively significant information. The concluded working hypothesis is that immediate effects of high concentration of cortisol may facilitate stress-coping via inhibition of automatic processing of goal-irrelevant threatening information and through increased automatic approach-avoidance responses in early emotional processing. Limitations in the existing literature and suggestions for future directions are briefly discussed. Copyright © 2010 Elsevier Ltd. All rights reserved.

  9. Parents' reactions to children's stuttering and style of coping with stress.

    2016-09-01

    The aim of the research was to determine: (a) how parents react to their child's stuttering, (b) what stress coping strategies they utilise, as well as (c) whether stress coping style depends on parents' reaction to their child's stuttering. The research involved 23 mothers and 23 fathers of children who stutter (CWS) at the age of three to six years old. The Reaction to Speech Disfluency Scale (RSDS), developed by the authors, was used in the research. To determine the parents' coping the Coping Inventory in Stressful Situations (CISS) by N.S. Endler and D.A Parker was applied. The strongest reactions are observed on the cognitive level. Stronger cognitive, emotional and behavioural reactions are observed in the mothers towards their disfluently speaking sons and in the fathers towards their daughters. Having analysed the profiles of coping styles, it can be noticed that the task-oriented coping is most frequently adapted by the fathers. The mothers most often use the avoidance-oriented coping. No relevant correlation was observed between the fathers' coping style and their reactions to the child's disfluent speech. As far as the mothers are concerned, it has been proved that an increase in behavioural reactions correlates with the avoidance-oriented coping. The cognitive reactions of the parents' towards their child's stuttering were most frequent, while the emotional ones were the least frequent. Confronted with a stressful situation, the fathers most often adapt the task-oriented coping, whereas the mothers use the avoidance-oriented coping. the reader will be able to (1) learn what the key reactions of parents to their children's stuttering are, (2) describe stuttering as a stress factor for the parents, (3) describe the factors which influence parents' reactions to their child's stuttering and their coping style.

    2011-01-01

    We describe experiments that isolate and characterize multiple adaptable mechanisms that influence responses of orientation-selective neurons in primary visual cortex (V1) of anesthetized macaque (Macaca fascicularis). The results suggest that three adaptable stages of machinery shape neural responses in V1: a broadly-tuned early stage and a spatio-temporally tuned later stage, both of which provide excitatory input, and a normalization pool that is also broadly tuned. The early stage and the normalization pool are revealed by adapting gratings that themselves fail to evoke a response from the neuron: either low temporal frequency gratings at the null orientation or gratings of any orientation drifting at high temporal frequencies. When effective, adapting stimuli that altered the sensitivity of these two mechanisms caused reductions of contrast gain and often brought about a paradoxical increase in response gain due to a relatively greater desensitization of the normalization pool. The tuned mechanism is desensitized only by stimuli well-matched to a neuron’s receptive field. We could thus infer desensitization of the tuned mechanism by comparing effects obtained with adapting gratings of preferred and null orientation modulated at low temporal frequencies. PMID:22016535

    The main aim of this study was to investigate the gender differences in defense mechanisms, ways of coping with stress and identity formation in relation to adolescent suicidal behavior. This study involved 64 adolescents between 12-17 years of age, who were admitted to the emergency service with a suicide attempt. They were evaluated with a semi-structured clinical interview (K-SADS), Ways of Coping Inventory (WCI), Defense Mechanisms Inventory (DMI) and Sense of Identity Assessment Form (SIAF). 60.9% (n = 39) of the adolescents were female, and 39.1% (n=25) were male. There were no statistically significant differences between the girls and the boys with respect to the clinical characteristics of the suicide attempt and the rate of psychiatric disorders. Of the 64 adolescents with suicide attempt, 47 (73.4%) had at least one, and 26 (40.6%) had more than one psychiatric disorder according to K-SADS. Disruptive behavior disorders were more frequent in males, whereas depression was more frequent in girls. The data indicated the importance of identity confusion, major depression and ADHD in adolescents with suicide attempt in both genders. 43.6% (n=17) of the girls and 36% (n=9) of the boys obtained scores higher than the cut-off point of SIAF indicating identity confusion. Professional help seeking and NSSI behaviors before the suicide attempt were more common in adolescents with identity confusion. While there were differences between genders with respect to the defense mechanisms used, no significant difference was found in terms of ways of coping. Evaluation of DMI scores revealed that the turning against object subscale score was significantly higher in boys compared to girls. While evaluating the adolescents at risk, their defense mechanisms, way of coping and sense of identity, as well as their psychiatric diagnosis should be assessed in detail in order to identify the suicidal thoughts and prevent possible suicide attempts.

  14. Personality, coping style and well-being of parents rearing children with developmental disabilities.

    2006-12-01

    Parents with children with developmental disabilities (DD) encounter a variety of stressors associated with rearing their children and must develop effective coping mechanisms in order to adapt successfully to these challenges. Previous research has failed to establish the role of parental individual differences in the reported use of different coping strategies. The current study explores parental personality and whether children with DD were adopted or born into the families and their influence on the coping strategies used by mothers and fathers. A total of 97 mother-father dyads rearing at least one child with DD were participants. They narrated stressful situations related to their child and completed the Ways of Coping Questionnaire twice. Data were also collected with regard to personality, depression and subjective well-being (SWB). Both adoptive and birth mothers and fathers used more problem-focused than emotion-focused strategies. Personality factors, Neuroticism especially, were predictive of coping strategy use. Higher levels of Positive Reappraisal were associated with higher levels of SWB, whereas higher levels of Escape-Avoidance were associated with lower levels of SWB, but only for mothers. Results were consistent with a dispositional model of strategy use in that frequency of use was associated with personality characteristics, was consistent over time, and for different children in the same families. Future research should focus on the persistence of the associations between strategy use and well-being and whether they hold true at different stages of the lifespan when coping contexts may change quite dramatically.

    2016-01-01

    The authors investigated adolescents' use of coping strategies in relation to attachment to parents and time perspective. Adolescents in Grade 3 upper secondary school (M age = 18.3 years, SD = 0.6 years; n = 160) completed the Inventory of Parent and Peer Attachment, the Zimbardo Time Perspective Inventory, and the Brief COPE. Correlational analyses showed that attachment to parents was associated with a more favorable view of the past (higher past positive and lower past negative), a less fatalistic view of the present, and a more favorable view of the future (higher future positive and lower future negative). Parental attachment accounted for significant variance in composite coping scores (adaptive and maladaptive) when entered before, but not after, time perspective subscales in hierarchical regression analyses. However, time perspective (mainly present hedonistic and positive or negative future) predicted adaptive or maladaptive coping over and beyond attachment. The results are consistent with the hypothesis that most of the relationship between adolescents' attachment to parents and coping is mediated by individual differences in time perspective. By contrast, factors other than attachment to parents (e.g., temperament) must be considered to fully account for the relationship between time perspective and coping.

  16. Mechanisms of small intestinal adaptation.

    PubMed

    Jenkins, A P; Thompson, R P

    1994-01-01

    Luminal nutrition, hormonal factors and pancreaticobiliary secretions are probably the major mediators of small intestinal adaptation. Their actions, as discussed in this paper, are likely to be interrelated. Direct local enterotrophic effects cannot account for all the actions of luminal nutrients. Additionally, hormonal factors have been shown to contribute to indirect effects of luminal nutrients and enteroglucagon is a likely mediator of adaptive responses. Furthermore, epidermal growth factor is a peptide for which there is convincing evidence of an enterotrophic action. Attention is drawn to the fact that pancreaticobiliary secretions may have a physiological role in stimulating small intestinal mucosal proliferation. Other factors may also influence small intestinal mucosal proliferation (e.g. prostaglandins, neurovascular mechanisms, bacteria). Additionally, polyamines are crucial in initiating cell division in the small intestine, but the detailed mechanisms of their action require further clarification. Finally, a number of therapeutic applications of small intestinal epithelial cell proliferation are discussed.

    Resilience is important in sport performers to withstand the pressure they experience. This study analyzed the relationship among resilient qualities and coping strategies in 235 Spanish athletes (126 males, 109 females; M age = 20.7 yr) who practiced different sports (79.1% team sports, 20.9% individual sports). They were evaluated at the beginning of the last competitive mesocycle and after an important competition. Coping strategies and level of resilient qualities were measured by the Coping Inventory for Competitive Sport and the Resilience Scale. There was no significant difference in resilience scores between evaluations performed during the last mesocycle or competition. A significant increase occurred in the scores for emotion-oriented and distraction-oriented coping during competition. Resilience scores correlated positively to task-oriented coping and negatively to disengagement- and distraction-oriented coping during both periods. Analysis of variance indicated that athletes with high individual resilient qualities reached higher scores in task-oriented coping, using to a lower extent disengagement- and distraction-oriented coping. Results obtained suggest that resilient characteristics may associate in athletes to the use of more potentially adaptative coping strategies. © The Author(s) 2016.

    Emotional resilience enhances an animal's ability to maintain physiological allostasis and adaptive responses in the midst of challenges ranging from cognitive uncertainty to chronic stress. In the current study, neurobiological factors related to strategic responses to uncertainty produced by prediction errors were investigated by initially profiling male rats as passive, active or flexible copers (n = 12 each group) and assigning to either a contingency-trained or non-contingency trained group. Animals were subsequently trained in a spatial learning task so that problem solving strategies in the final probe task, as well-various biomarkers of brain activation and plasticity in brain areas associated with cognition and emotional regulation, could be assessed. Additionally, fecal samples were collected to further determine markers of stress responsivity and emotional resilience. Results indicated that contingency-trained rats exhibited more adaptive responses in the probe trial (e.g., fewer interrupted grooming sequences and more targeted search strategies) than the noncontingent-trained rats; additionally, increased DHEA/CORT ratios were observed in the contingent-trained animals. Diminished activation of the habenula (i.e., fos-immunoreactivity) was correlated with resilience factors such as increased levels of DHEA metabolites during cognitive training. Of the three coping profiles, flexible copers exhibited enhanced neuroplasticity (i.e., increased dentate gyrus doublecortin-immunoreactivity) compared to the more consistently responding active and passive copers. Thus, in the current study, contingency training via effort-based reward (EBR) training, enhanced by a flexible coping style, provided neurobiological resilience and adaptive responses to prediction errors in the final probe trial. These findings have implications for psychiatric illnesses that are influenced by altered stress responses and decision-making abilities (e.g., depression). PMID:24808837

    The fields of plant water relations and plant biomechanics have traditionally been studied separately even though often the same tissues are responsible for water transport and mechanical support. There is now increasing evidence that hydraulic and mechanical adaptations may influence one another. We studied the changes in the hydraulic and mechanical properties of the wood along lateral roots of two species of buttressed trees. In these roots, the mechanical contstraints quantified by strain measurements are known to decrease distally. Further, we investigated the effect of mechanical loading on the vessel anatomy in these and four other species of tropical trees. We found that as the strain decreased, the wood became progressively less stiff and strong but the conductivity increased exponentially. This was reflected in that adaptations towards re-enforcing mechanically loaded areas resulted in xylem with fewer and smaller vessels. In addition a controlled growth experiment on three tree species showed that drought adaptation may results in plants with stronger and stiffer tissue. Our results indicate that hydraulic and mechanical stress adaptations may be interrelated, and so support recent studied suggesting that physiological responses are complex balances rather than pure optimisations.

    In humans, coping behaviour is an action taken to soothe oneself during or after a stressful or threatening situation. Some human behaviours with physiological functions also serve as coping behaviours, for example, comfort sucking in infants and comfort eating in adults. In birds, the behaviour of preening, which has important physiological functions, has been postulated to soothe individuals after stressful situations. We combine two existing modelling approaches - logistic regression and Darwinian dynamics - to explore theoretically how a behaviour with crucial physiological function might evolve into a coping behaviour. We apply the method to preening in colonial seabirds to investigate whether and how preening might be co-opted as a coping behaviour in the presence of predators. We conduct an in-depth study of the environmental correlates of preening in a large gull colony in Washington, USA, and we perform an independent field test for comfort preening by computing the change in frequency of preening in gulls that were alerted to a predator, but did not flee.

    Exposure to mass trauma has contributed to increasing concern about the well-being of children, families, and communities. In spite of global awareness of the dramatic impact of mass trauma on youth, little is known about how children and adolescents cope with and adapt to disasters and terrorism. While coping has yet to be fully conceptualized as a unified construct, the process of responding to stress includes recognized cognitive, emotional, and behavioral components. Unfortunately, research on the complex process of adaptation in the aftermath of mass trauma is a relatively recent focus. Further study is needed to build consensus in terminology, theory, methods, and assessment techniques to assist researchers and clinicians in measuring children's coping, both generally and within the context of mass trauma. Advancements are needed in the area of coping assessment to identify internal and external factors affecting children's stress responses. Additionally, enhanced understanding of children's disaster coping can inform the development of prevention and intervention programs to promote resilience in the aftermath of traumatic events. This article examines the theoretical and practical issues in assessing coping in children exposed to mass trauma, and includes recommendations to guide assessment and research of children's coping within this specialized context.

    Objective Couples facing metastatic breast cancer (MBC) must learn to cope with stressors that can affect both partners' quality of life as well as the quality of their relationship. Common dyadic coping involves taking a “we” approach, whereby partners work together to maintain their relationship while jointly managing their shared stress. This study prospectively evaluated whether common dyadic coping was associated with less cancer-related distress and greater dyadic adjustment for female MBC patients and their male partners. Design Couples (N = 191) completed surveys at the start of treatment for MBC (baseline), and 3 and 6 months later. Main Outcome Measures Cancer-related distress was assessed with the Impact of Events Scale; dyadic adjustment was assessed using the short-form of the Dyadic Adjustment Scale. Results Multilevel models using the couple as the unit of analysis showed that the effects of common positive dyadic coping on cancer-related distress significantly differed for patients and their partners. Whereas partners experienced slightly lower levels of distress, patients experienced slightly higher levels of distress. Although patients and partners who used more common negative dyadic coping experienced significantly greater distress at all times, the association was stronger for patients. Finally, using more common positive dyadic coping and less common negative dyadic coping was mutually beneficial for patients and partners in terms of greater dyadic adjustment. Conclusion Our findings underscore the importance of couples working together to manage the stress associated with MBC. Future research may benefit from greater focus on the interactions between patients and their partners to address ways that couples can adaptively cope together. PMID:20230090

    2014-01-01

    The existing empirical literature suggests that during difficult situations, the concurrent experience of positive and negative affects may be ideal for ensuring successful adaptation and well-being. However, different patterns of mixed emotions may have different adaptive consequences. The present research tested the proposition that experiencing a pattern of secondary mixed emotion (i.e., secondary emotion that embrace both positive and negative affects) more greatly promotes adaptive coping than experiencing two other patterns of mixed emotional experiences: simultaneous (i.e., two emotions of opposing affects taking place at the same time) and sequential (i.e., two emotions of opposing affects switching back and forth). Support for this hypothesis was obtained from two experiments (Studies 1 and 2) and a longitudinal survey (Study 3). The results revealed that secondary mixed emotions predominate over sequential and simultaneous mixed emotional experiences in promoting adaptive coping through fostering the motivational and informative functions of emotions; this is done by providing solution-oriented actions rather than avoidance, faster decisions regarding coping strategies (Study 1), easier access to self-knowledge, and better narrative organization (Study 2). Furthermore, individuals characterized as being prone to feeling secondary mixed emotions were more resilient to stress caused by transitions than those who were characterized as being prone to feeling opposing emotions separately (Study 3). Taken together, the preliminary results indicate that the pattern of secondary mixed emotion provides individuals with a higher capacity to handle adversity than the other two patterns of mixed emotional experience.

  9. Importance of plasticity and local adaptation for coping with changing salinity in coastal areas: a test case with barnacles in the Baltic Sea

    PubMed Central

    2014-01-01

    Background Salinity plays an important role in shaping coastal marine communities. Near-future climate predictions indicate that salinity will decrease in many shallow coastal areas due to increased precipitation; however, few studies have addressed this issue. The ability of ecosystems to cope with future changes will depend on species’ capacities to acclimatise or adapt to new environmental conditions. Here, we investigated the effects of a strong salinity gradient (the Baltic Sea system – Baltic, Kattegat, Skagerrak) on plasticity and adaptations in the euryhaline barnacle Balanus improvisus. We used a common-garden approach, where multiple batches of newly settled barnacles from each of three different geographical areas along the Skagerrak-Baltic salinity gradient were exposed to corresponding native salinities (6, 15 and 30 PSU), and phenotypic traits including mortality, growth, shell strength, condition index and reproductive maturity were recorded. Results We found that B. improvisus was highly euryhaline, but had highest growth and reproductive maturity at intermediate salinities. We also found that low salinity had negative effects on other fitness-related traits including initial growth and shell strength, although mortality was also lowest in low salinity. Overall, differences between populations in most measured traits were weak, indicating little local adaptation to salinity. Nonetheless, we observed some population-specific responses – notably that populations from high salinity grew stronger shells in their native salinity compared to the other populations, possibly indicating adaptation to differences in local predation pressure. Conclusions Our study shows that B. improvisus is an example of a true brackish-water species, and that plastic responses are more likely than evolutionary tracking in coping with future changes in coastal salinity.

    The aim of this research was to jointly test effects of work stressors and coping strategies on job performance among employees in the Greater China region. A self-administered survey was conducted to collect data from three major cities in the region, namely Beijing, Hong Kong, and Taipei (N = 380). Four important work stressors were assessed: heavy workload, organizational constraints, lack of work autonomy, and interpersonal conflict. We used a four-factor model of Chinese coping strategies composed of hobbies/relaxation, active action, seeking social support, and passive adaptation. Job performance was indicated by both task performance (quantity of work, quality of work, job knowledge) and contextual performance (attendance, getting along with others). We found that: (1) work stressors were related to job performance. Specifically, workload had a positive relation with quantity of work, whereas organizational constraints had negative relations with quantity of work and attendance. In addition, interpersonal conflict had a negative relation with getting along with others. (2) Chinese positive coping strategies were positively related to job performance. Specifically, seeking social support had positive relations with quantity of work and getting along with others, whereas active action had positive relations with attendance and job knowledge. (3) Chinese passive adaptation coping behaviors were negatively related to job performance. Specifically, passive adaptation had negative relations with quantity of work, quality of work, and getting along with others. The present study thus found joint effects of work stressors and coping behaviors among Chinese employees in the Greater China region, encompassing three sub-societies of mainland China, Hong Kong, and Taiwan. Differential effects of Chinese positive and passive coping strategies were also noted. Most importantly, all these effects were demonstrated on multiple indicators of job performance, a rarely studied

    This article introduces the Brief Resilient Coping Scale (BRCS), a 4-item measure designed to capture tendencies to cope with stress in a highly adaptive manner. Two samples of individuals with rheumatoid arthritis (ns = 90 and 140) provide evidence for the reliability and validity of the BRCS. The BRCS has adequate internal consistency and…

  12. Differences in the catalytic mechanisms of mesophilic and thermophilic indole-3-glycerol phosphate synthase enzymes at their adaptive temperatures.

    Thermophilic enzymes tend to be less catalytically-active at lower temperatures relative to their mesophilic counterparts, despite having very similar crystal structures. An often cited hypothesis for this general observation is that thermostable enzymes have evolved a more rigid tertiary structure in order to cope with their more extreme, natural environment, but they are also less flexible at lower temperatures, leading to their lower catalytic activity under mesophilic conditions. An alternative hypothesis, however, is that complementary thermophilic-mesophilic enzyme pairs simply operate through different evolutionary-optimized catalytic mechanisms. In this communication, we present evidence that while the steps of the catalytic mechanisms for mesophilic and thermophilic indole-3-glycerol phosphate synthase (IGPS) enzymes are fundamentally similar, the identity of the rate-determining step changes as a function of temperature. Our findings indicate that while product release is rate-determining at 25°C for thermophilic IGPS, near its adaptive temperature (75°C), a proton transfer event, involving a general acid, becomes rate-determining. The rate-determining steps for thermophilic and mesophilic IGPS enzymes are also different at their respective, adaptive temperatures with the mesophilic IGPS-catalyzed reaction being rate-limited before irreversible CO2 release, and the thermophilic IGPS-catalyzed reaction being rate limited afterwards.

  13. Theory of psychological adaptive modes.

    PubMed

    Lehti, Juha

    2016-05-01

    When an individual is facing a stressor and normal stress-response mechanism cannot guarantee sufficient adaptation, special emotional states, adaptive modes, are activated (for example a depressive reaction). Adaptive modes are involuntary states of mind, they are of comprehensive nature, they interfere with normal functioning, and they cannot be repressed or controlled the same way as many emotions. Their transformational nature differentiates them from other emotional states. The object of the adaptive mode is to optimize the problem-solving abilities according to the situation that has provoked the mode. Cognitions and emotions during the adaptive mode are different than in a normal mental state. These altered cognitions and emotional reactions guide the individual to use the correct coping skills in order to deal with the stressor. Successful adaptation will cause the adaptive mode to fade off since the adaptive mode is no longer necessary, and the process as a whole will lead to raised well-being. However, if the adaptation process is inadequate, then the transformation period is prolonged, and the adaptive mode will turn into a dysfunctional state. Many psychiatric disorders are such maladaptive processes. The maladaptive processes can be turned into functional ones by using adaptive skills that are used in functional adaptive processes.

  14. Vestibulospinal adaptation to microgravity

    Human balance control is known to be transiently disrupted after spaceflight; however, the mechanisms responsible for postflight postural ataxia are still under investigation. In this report, we propose a conceptual model of vestibulospinal adaptation based on theoretical adaptive control concepts and supported by the results from a comprehensive study of balance control recovery after spaceflight. The conceptual model predicts that immediately after spaceflight the balance control system of a returning astronaut does not expect to receive gravity-induced afferent inputs and that descending vestibulospinal control of balance is disrupted until the central nervous system is able to cope with the newly available vestibular otolith information. Predictions of the model are tested using data from a study of the neurosensory control of balance in astronauts immediately after landing. In that study, the mechanisms of sensorimotor balance control were assessed under normal, reduced, and/or altered (sway-referenced) visual and somatosensory input conditions. We conclude that the adaptive control model accurately describes the neurobehavioral responses to spaceflight and that similar models of altered sensory, motor, or environmental constraints are needed clinically to predict responses that patients with sensorimotor pathologies may have to various visual-vestibular or changing stimulus environments.

    In this study, we investigated the validity of the Trait Emotional Intelligence Questionnaire-Short Form (TEIQue-SF; Petrides, 2009) in the context of task-induced stress. We used a total sample of 225 volunteers to investigate (a) the incremental validity of the TEIQue-SF over other predictors of coping with task-induced stress, and (b) the construct validity of the TEIQue-SF by examining the mechanisms via which scores from the TEIQue-SF predict coping outcomes. Results demonstrated that the TEIQue-SF possessed incremental validity over the Big Five personality traits in the prediction of emotion-focused coping. Results also provided support for the construct validity of the TEIQue-SF by demonstrating that this measure predicted adaptive coping via emotion-focused channels. Specifically, results showed that, following a task stressor, the TEIQue-SF predicted low negative affect and high task performance via high levels of emotion-focused coping. Consistent with the purported theoretical nature of the trait emotional intelligence (EI) construct, trait EI as assessed by the TEIQue-SF primarily enhances affect and performance in stressful situations by regulating negative emotions.

    The Coping Strategies Scale (CSS) was designed to assess adaptive changes in substance-use specific coping that result from treatment. The present study sought to examine the latent structure of the CSS in the hope that it might shed light on the coping processes of drug users, and guide the development of a brief version of the CSS. Respondents on the CSS were 751 men and women treated in three clinical trials for marijuana dependence. Posttreatment CSS data were analyzed to determine the nature of coping responses in patients who have been trained to use specific strategies to deal with substance use disorders. Exploratory factor analysis yielded two factors, categorized as problem-focused and emotion-focused coping, but confirmatory factor analysis did not support this structure. When infrequently endorsed items were removed, however, confirmatory factor analysis revealed a good fit to the data. Contrary to expectations, practical strategies that often form the basis for coping skills training, such as avoiding those who smoke, were not frequently endorsed. Problem focused items reflected cognitive commitments to change. Emotion-focused items included cognitive reinterpretations of emotions, to help manage emotional reactions. Brief versions of the CSS based on these factors showed good convergent and discriminant validity. The CSS, and the brief versions of the CSS, may prove useful in future treatment trials to evaluate effects of treatment on coping skills acquisition and utilization in substance dependent individuals.

    The aim of this article is to analyze the relation between dispositional optimism and coping with chronic pain. The study seeks to define the relation between life orientation (optimism vs. pessimism) and coping with pain (believes about pain control and the choice of coping strategy). The following questionnaires were used: LOT-R - Life Orientation Test, BPCQ - The Beliefs about Pain Control Questionnaire and CSQ - The Pain Coping Strategies Questionnaire. The results show that dispositional optimism correlates positively with: internal locus of pain control r=0.6, P<0.01; declared coping with pain r=0.38, P<0.05; diverting attention r = 0.93, P<0.01; and behavioral activity r = 0.82, P<0.01. Dispositional optimism correlates negatively with catastrophizing r = -0.28, P<0.05. We conclude that dispositional optimism plays a key role in forming the mechanisms of coping with chronic pain and thereby in improving the psychophysical comfort of patients.

    Background: Past research studies on the exploration of attributes to the stress of doctors/medical interns were reported more often than the types of coping strategies, healthy practices to strengthen their internal resources to deal effectively with the stressful situations. Objectives: The present study was conducted to find such internal resource – “mindfulness” as a mediator of coping, perceived stress, and job satisfaction among medical interns. Methods: A cross-sectional descriptive study comprised 120 medical interns forms from various medical colleges in Mangalore were recruited and completed the assessment on mindfulness, cognitive-emotive regulation, coping strategies, perceived stress, and job satisfaction from doctoral interns were collected. Results: Initial correlation analysis results indicate that adaptive coping strategies significantly associate with greater mindfulness and less perceived stress. In turn, mindfulness is negatively correlated with nonadaptive coping strategies and perceived. Job satisfaction showed no significant relationship with any of the other variables. Mediational models indicate that the relationship between adaptive coping strategies and perceived stress was significantly mediated by mindfulness. Furthermore, partial mediation between nonadaptive strategies and perceived stress through mindfulness indicates that respondents reported a high level of nonadaptive strategy experience and a lower level of mindfulness can be counterproductive as they encourage the ineffective way to deal with the stresses. Conclusion: The implication of the results were discussed with suggesting a possible intervention to improve the adaptive strategies and mindfulness among the medical interns. PMID:28659700

    Using cluster analytical procedure, this study aimed (i) to determine whether people could be differentiated on the basis of coping profiles (or unique combinations of coping strategies); and (ii) to examine the relationships between these profiles and perceived stress and health-related behaviors. A sample of 578 French students (345 females, 233 males; M(age)= 21.78, SD(age)= 2.21) completed the Perceived Stress Scale-14 ( Bruchon-Schweitzer, 2002), the Brief COPE ( Muller and Spitz, 2003) and a series of items measuring health-related behaviors. A two-phased cluster analytic procedure (i.e. hierarchical and non-hierarchical-k-means) was employed to derive clusters of coping strategy profiles. The results yielded four distinctive coping profiles: High Copers, Adaptive Copers, Avoidant Copers and Low Copers. The results showed that clusters differed significantly in perceived stress and health-related behaviors. High Copers and Avoidant Copers displayed higher levels of perceived stress and engaged more in unhealthy behavior, compared with Adaptive Copers and Low Copers who reported lower levels of stress and engaged more in healthy behaviors. These findings suggested that individuals' relative reliance on some strategies and de-emphasis on others may be a more advantageous way of understanding the manner in which individuals cope with stress. Therefore, cluster analysis approach may provide an advantage over more traditional statistical techniques by identifying distinct coping profiles that might best benefit from interventions. Future research should consider coping profiles to provide a deeper understanding of the relationships between coping strategies and health outcomes and to identify risk groups. © The Author 2014.

    Many studies have reported on the perceptions of medical students toward dissection. It is important to understand the feelings and symptoms experienced during dissection so that they can be adequately handled. Prior to dissection, first year students are given lectures on aspects of dissection, death and dying, and death rituals in various cultures. Two separate questionnaires, one given during the first week of dissection and another given one month into the program were then completed anonymously by dissection groups. The questions were designed to be open-ended, thereby encouraging group discussion amongst students. The questionnaires were used to determine the perception of students to dissection and to discover if these perceptions change during the dissection program. The first questionnaire revealed that students do experience fears and anxiety prior to and at the beginning of dissection; however, most of these fears dissipated by the time of the second questionnaire. One month into dissection students cited talking to peers as their main coping mechanism and fewer students mentioned emotional detachment from their cadaver as a coping mechanism, as was the case in the first questionnaire. Dissection was perceived as a positive experience by our student cohort and most students cited the main advantage of dissection as the ability to visualize organs in three dimensions. The comprehensive answers received from the students indicated that thorough discussion of feelings amongst peers occurred, introducing students to an important coping mechanism at an early stage of their learning.

    Smoking is a coping strategy for many smokers who then have difficulty finding new ways to cope with negative affect when they quit. This paper describes analyses conducted to develop and evaluate item banks for assessing the coping expectancies of smoking for daily and nondaily smokers. Using data from a large sample of daily (N = 4,201) and nondaily (N = 1,183) smokers, we conducted a series of item factor analyses, item response theory analyses, and differential item functioning (DIF) analyses (according to gender, age, and ethnicity) to arrive at a unidimensional set of items for daily and nondaily smokers. We also evaluated performance of short forms (SFs) and computer adaptive tests (CATs) for assessing coping expectancies of smoking. For both daily and nondaily smokers, the unidimensional Coping Expectancies item banks (21 items) are relatively DIF free and are highly reliable (0.96 and 0.97, respectively). A common 4-item SF for daily and nondaily smokers also showed good reliability (0.85). Adaptive tests required an average of 4.3 and 3.7 items for simulated daily and nondaily respondents, respectively, and achieved reliabilities of 0.91 for both when the maximum test length was 10 items. This research provides a new set of items that can be used to reliably assess coping expectancies of smoking, through a SF, CAT, or a tailored set selected for a specific research purpose. © The Author 2014.

    Epilepsy, a common problem in child neurology, affects the entire family. There is a potential for such psychosocial consequences as parental chronic sorrow and alterations in coping. In this study, 67 parents completed brief questionnaires about their sorrow and coping styles. Results demonstrated chronic sorrow as measured by the Adapted Burke Questionnaire (10.45 +/- 7.9). Interestingly, the total score was not significantly different between parents of children with refractory and nonrefractory epilepsy or parents of children with comorbid or without comorbid conditions. Selection of the individual item disbelief, however, was significantly increased in parents of children with nonrefractory epilepsy, and selection of the item anger was significantly increased in parents of children with comorbid conditions. Parental coping styles were similar to those reported in the normative data for the instrument used, the Coping Health Inventory for Parents (CHIP). The correlation between chronic sorrow and coping was significant between the grief component of sorrow and Coping Pattern II of the CHIP. Implications for practice include earlier identification of parental feelings of sorrow and coping styles, which may contribute to a positive outcome.

    The main objective of this study was to investigate whether the personality dimension of conformism/nonconformism was a predictor of stress coping styles in athletes training combat sports, and to present the characteristics of this personality dimension in the context of the competitors' adaptive/innovative sport performance. Scores of 346 males practising combat sports such as kick boxing, MMA, thai boxing, boxing and wrestling were analyzed. The participants completed the Creative Behaviour Questionnaire (KANH III) measuring the conformity/nonconformity personality dimension and the Coping Inventory for Stressful Situations (CISS) measuring stress coping styles. The comparative analyses were conducted only for the groups of conformists and nonconformists. Differences in stress coping styles between conformists and nonconformists training combat sports were found as nonconformists tended to prefer the task-oriented coping style. Conclusively, a higher rate of nonconformity was associated with increasingly frequent occurrence of task-oriented coping and decreasingly frequent emotion-oriented coping.

    Large-scale human interaction through, for example, financial markets causes ceaseless random changes in outcome variability, producing frequent and salient outliers that render the outcome distribution more peaked than the Gaussian distribution, and with longer tails. Here, we study how humans cope with this evolutionary novel leptokurtic noise, focusing on the neurobiological mechanisms that allow the brain, 1) to recognize the outliers as noise and 2) to regulate the control necessary for adaptive response. We used functional magnetic resonance imaging, while participants tracked a target whose movements were affected by leptokurtic noise. After initial overreaction and insufficient subsequent correction, participants improved performance significantly. Yet, persistently long reaction times pointed to continued need for vigilance and control. We ran a contrasting treatment where outliers reflected permanent moves of the target, as in traditional mean-shift paradigms. Importantly, outliers were equally frequent and salient. There, control was superior and reaction time was faster. We present a novel reinforcement learning model that fits observed choices better than the Bayes-optimal model. Only anterior insula discriminated between the 2 types of outliers. In both treatments, outliers initially activated an extensive bottom-up attention and belief network, followed by sustained engagement of the fronto-parietal control network. PMID:26850528

    2009-01-01

    Coping has been suggested as an important element in understanding the long-term functioning of individuals with a history of child sexual abuse (CSA). The present review synthesizes the literature on coping with CSA, first by examining theories of coping with trauma, and, second by examining how these theories have been applied to studies of coping in samples of CSA victims. Thirty-nine studies were reviewed, including eleven descriptive studies of the coping strategies employed by individuals with a history of CSA, eighteen correlational studies of the relationship between coping strategies and long-term functioning of CSA victims, and ten investigations in which coping was examined as a mediational factor in relation to long-term outcomes. These studies provide initial information regarding early sexual abuse and subsequent coping processes. However, this literature is limited by several theoretical and methodological issues, including a failure to specify the process of coping as it occurs, a disparity between theory and research, and limited applicability to clinical practice. Future directions of research are discussed and include the need to understand coping as a process, identification of coping in relation to adaptive outcomes, and considerations of more complex mediational and moderational processes in the study of coping with CSA.

    The association between marital discord and depression is well established. Marital discord is hypothesized to be a stressful life event that would evoke one’s efforts to cope with it. In an effort to further understand the nature of this association, the current study investigated coping as a mediating variable between marital dissatisfaction and depression and between marital instability and depression. Both marital dissatisfaction and instability, reflecting orthogonal dimensions of marital discord, were included in the model examined to elucidate a more complete picture of marital functioning. Structural Equation Modeling analyses revealed that coping mediated the association between marital instability and depression, but not marital dissatisfaction and depression, suggesting that coping traditionally considered adaptive for individuals in the context of controllable stressors may not be adaptive in the context of couple relationship instability. The findings also have implications for interventions focusing on decreasing maladaptive coping strategies in couples presenting for marital therapy or depression in addition to efforts directed at improving marital quality.

    The shortage of freshwater resource in many countries leads to a shift to develop aquaculture in brackish water and sea water. Tilapias are euryhaline that can thrive from freshwater to full sea water. They and their hybrids are the best candidate species for cultivation in brackish habitats. Thus, understanding their osmoregulatory mechanisms will help to breed or genetically engineer salt tolerant species. In this paper, we review recent progress in understanding the mechanisms of osmoregulatory adaptations in tilapia.

    cancer may face and more insight on how to expand the dyadic coping of these coupes might facilitate improvements in the quality of cancer care. Couple-based intervention studies may increase the couples' relationship functioning. However, future research is needed to examine more specifically which couples may benefit from such interventions. Statement of contribution What is already known on this subject? Dyadic coping may influence the distress experienced by both members of the couple and their relationship functioning. Several reviews already reported on the potential of couple-based interventions to improve the dyadic coping of couples coping with cancer and on the beneficial effects of this coping on the psychosocial adjustment and relationship functioning of patients and partners (e.g., Badr & Krebs, 2012; Martire, Shulz, Helgeson, Small, & Saghafi, 2010; Regan et al., 2012). However, even though we now know that couple-based intervention might be useful, no systematic review has been conducted that focuses specifically on the mechanisms of dyadic coping itself. What does this study add? This review showed the importance of stress communication, supportive behaviours, and positive dyadic coping for the maintenance or enhancement of relationship functioning in couples coping with cancer. In addition, the dyadic intervention studies send an important message that encourages to further examine the potential benefit of such interventions in future. However, more consensus in the conceptualization and assessment of the dyadic coping styles is needed in order to increase the comparability of the reported findings. © 2014 The British Psychological Society.

    Coping with arthritis-related stress has been extensively studied. However, limited evidence exists regarding coping with stress extraneous to the disease (life stress). This study explored life stress and coping in a subset of older women with osteoarthritis from a larger longitudinal study. An Australian regional university. This qualitative study involved semistructured telephone interviews. Potential participants were mailed a letter of invitation/participant information statement by the Australian Longitudinal Study on Women's Health (ALSWH). Invitations were sent out in small batches (primarily 10). Interviews were conducted until data saturation was achieved using a systematic process (n=19). Digitally recorded interviews were transcribed verbatim and deidentified. Data were thematically analysed. Women who indicated being diagnosed or treated for arthritis in the previous 3 years in the fifth survey of the ALSWH (conducted in 2007) provided the sampling frame. Potential participants were randomly sampled by a blinded data manager using a random number generator. Coping with life stress involved both attitudinal coping processes developed early in life (ie, stoicism) and transient cognitive and support-based responses. Women also described a dualistic process involving a reduction in the ability to cope with ongoing stress over time, coupled with personal growth. This is the first study to examine how individuals cope with non-arthritis-related stress. The findings add to the current understanding of stress and coping, and have implications regarding the prevention of arthritis in women. Importantly, this study highlighted the potential detrimental impact of persistent coping patterns developed early in life.

    The oncology staff is at high risk for developing psychological disorders and burnout. In this study, we aimed to evaluate their burnout levels, job satisfaction, psychological statement and ways of coping with stress and the relationship between these variables and their sociodemographic and occupational characteristics. Among all health workers at the Istanbul University Institute, of Oncology, 159 were included in the study. A sociodemographic data form, the Maslach Burnout Inventory, the Minnesota Job Satisfaction Questionnaire, the General Health Questionnaire (GHQ) and the Styles of Coping Inventory-Short Form were used to evaluate burnout and its contributing factors. High levels of 'emotional exhaustion', 'depersonalization' and 'low sense of personal accomplishment' were determined in 30.2%, 8.2% and 44% of all participants, respectively. The variables that affected emotional exhaustion were assessed by logistic regression analysis. Accordingly, the ratio of emotional exhaustion was approximately 10 times higher in those for whom job stress was the most important stress factor compared with those who indicated nonjob stress for each one point increase on the GHQ and depersonalization scores, which were other predictors, with odds ratio (OR) : 1.23, p = 0.006 and OR : 1.67, p < 0.001, respectively. A negative correlation was detected between adaptive coping styles and 'burnout,' and a positive correlation was found between maladaptive coping strategies and exhaustion. It is necessary to monitor the psychological status of employees in oncology units with scanning tools such as GHQ to understand their job stress perceptions and to help them develop adaptive coping methods.

  13. Adaptive mechanism-based congestion control for networked systems

    2013-03-01

    In order to assure the communication quality in network systems with heavy traffic and limited bandwidth, a new ATRED (adaptive thresholds random early detection) congestion control algorithm is proposed for the congestion avoidance and resource management of network systems. Different to the traditional AQM (active queue management) algorithms, the control parameters of ATRED are not configured statically, but dynamically adjusted by the adaptive mechanism. By integrating with the adaptive strategy, ATRED alleviates the tuning difficulty of RED (random early detection) and shows a better control on the queue management, and achieve a more robust performance than RED under varying network conditions. Furthermore, a dynamic transmission control protocol-AQM control system using ATRED controller is introduced for the systematic analysis. It is proved that the stability of the network system can be guaranteed when the adaptive mechanism is finely designed. Simulation studies show the proposed ATRED algorithm achieves a good performance in varying network environments, which is superior to the RED and Gentle-RED algorithm, and providing more reliable service under varying network conditions.

    The skeleton adapts to a changing mechanical environment but the widely held concept that bone cells are programmed to respond to local mechanical loads to produce an optimal mechanical structure is not consistent with the high frequency of bone fractures. Instead, the author suggests that other important functions of bone compete with mechanical adaptation to determine structure. As a consequence of competing demands, bone architecture never achieves an optimal mechanical structure. c2001 Lippincott Williams & Wilkins, Inc.

    Insulin secretion must be tightly coupled to nutritional state to maintain blood glucose homeostasis. To this end, pancreatic β-cells sense and respond to changes in metabolic conditions, thereby anticipating insulin demands for a given physiological context. This is achieved in part through adjustments of nutrient metabolism, which is controlled at several levels including allosteric regulation, posttranslational modifications, and altered expression of metabolic enzymes. In this review, we discuss mechanisms of β-cell metabolic and functional adaptation in the context of two physiological states that alter glucose-stimulated insulin secretion: fasting and insulin resistance. We review current knowledge of metabolic changes that occur in the β-cell during adaptation and specifically discuss transcriptional mechanisms that underlie β-cell adaptation. A more comprehensive understanding of how β-cells adapt to changes in nutrient state could identify mechanisms to be co-opted for therapeutically modulating insulin secretion in metabolic disease.

    A mechanical attachment adapter was designed, constructed, and tested. The adapter was was included in a simulation program that investigated techniques for assembling erectable structures under simulated zero-g conditions by pressure-suited subjects in a simulated EVA mode. The adapter was utilized as an interface attachment between a simulated equipment module and one node point of a tetrahedral structural cell. The mating performance of the adapter, a self-energized mechanism, was easily and quickly demonstrated and required little effort on the part of the test subjects.

    This study examined the coping styles used by sexual minority men who have experienced intimate partner violence, including sexual, emotional and physical victimisation, as well as physical injury. Although sexual minority men experience intimate partner violence at least as often as do heterosexuals, there is currently limited knowledge of intimate partner violence in this community or resources for sexual minority men who experience intimate partner violence. Cross-sectional design. Sexual minority men (N = 89) were recruited as part of a national online survey and completed questionnaires assessing lifetime experiences of intimate partner violence as well as various coping strategies. In terms of intimate partner violence, 34·8% of participants reported having been targets of sexual abuse, 38·2% targets of physical abuse, 69·7% targets of psychological abuse and 28·1% had experienced an injury as a result of intimate partner violence during their lifetime. Canonical correlation analyses found that intimate partner violence victimisation explained 32·5% of the variance in adaptive and 31·4% of the variance in maladaptive coping behaviours. In the adaptive coping canonical correlation, standardised loadings suggested that sexual minority men who experienced intimate partner violence resulting in injury were more likely to use religious coping, but less likely to use planning coping. In the maladaptive coping canonical correlation, sexual minority men who had been targets of intimate partner sexual victimisation and intimate partner violence resulting in injury tended to engage in increased behavioural disengagement coping. This study revealed several coping behaviours that are more or less likely as the severity of different forms of intimate partner violence increases. The identification of these coping styles could be applied to the development and modification of evidence-based interventions to foster effective and discourage ineffective coping styles

    Introduction Stress coping has been defined as the cognitive and behavioral efforts made to conquer, endure, or decrease external and internal demands and the conflicts between them. It has two main elements: the control or modification of the person–environment relationship causing the stress (i.e., problem-focused coping) and/or regulation of stressful feelings (i.e., emotion-focused coping). Research suggests that the expressions of brain-derived neurotrophic factor (BDNF) and neurotrophic tyrosine kinase receptor type 2 (NTRK2) play important roles in brain adaptation to investigate stress. To clarify the genetic basis of stress coping, we investigated the association of stress-coping strategies and social adaptation with single-nucleotide polymorphisms (SNPs) involved in neural plasticity, anxiety, and depression. Methods In 252 healthy controls (94 women; 158 men), we measured and estimated the stress-coping style using the Lazarus-type stress-coping inventory, ego aptitude scale (EAS), and social adaptation self-evaluation scale (SASS). We investigated one SNP of BDNF (rs6265, Val/Met) and five SNPs of NTRK2 (rs11140800, rs1187286, rs1867283, rs1147198, and rs10868235). Results We observed significant associations between BDNF and emotion-focused strategies, seeking social support, self-control, and distancing. We also found significant associations between NTRK2 and cognitive strategies, problem-solving, confrontive- coping, seeking social support, distancing and positive reappraisal. Significant associations were also found between BDNF and critical attitudes and between NTRK2 and all seven ego-related factors on the EAS. In the SASS, the minor allele rs1867283 of NTRK2 had a significantly higher score than the heterozygote. Conclusions These findings may provide insights into the partial effects of genetic mutations in BDNF and NTRK2 on stress tolerance and personality. PMID:26445699

    Cognitive-behavioral treatments (CBT) are among the most popular interventions offered for alcohol and other substance use disorders, but it is not clear how they achieve their effects. CBT is purported to exert its beneficial effects by altering coping skills, but data supporting coping changes as the mechanism of action are mixed. The purpose of this pilot study was to test a treatment in which coping skills were trained in a highly individualized way, allowing us to determine if such training would result in an effective treatment. Participants were assigned randomly to a comprehensive packaged CBT program (PCBT), or to an individualized assessment and treatment program (IATP). The IATP program employed experience sampling via cellphone to assess coping skills prior to treatment, and provided therapists with a detailed understanding of patients' coping strengths and deficits. Out-patient treatment. A total of 110 alcohol-dependent men and women. Participants in both conditions completed experience sampling of situations, drinking and coping efforts prior to, and following, 12 weeks of treatment. Time-line follow-back procedures were also used to record drinking at baseline and post-treatment. IATP yielded higher proportion of days abstinent (PDA) at post-treatment (P < 0.05) than did PCBT, and equivalent heavy drinking days. IATP also elicited more momentary coping responses and less drinking in high-risk situations, as recorded by experience sampling at post-treatment. Post-treatment coping response rates were associated with decreases in drinking. The IATP approach was more successful than PCBT at training adaptive coping responses for use in situations presenting a high risk for drinking. The highly individualized IATP approach may prove to be an effective treatment strategy for alcohol-dependent patients.

    Objective The purpose of this study was to understand the impact of living with Klinefelter syndrome (XXY) as an adolescent or an adult and to examine the factors that contribute to adaptation. Methods Individuals (n = 310) aged 14–75 years with self-reported XXY were recruited from online support networks to complete a self-administered survey. Perceived consequences, perceived severity, perceived stigma, and coping were measured and evaluated as correlates of adaptation. Results The use of problem-focused coping strategies was positively correlated with adaptation (p < 0.01) and age was negatively correlated with adaptation (p < 0.05). Conclusion The majority of participants reported significant negative consequences of XXY, including infertility, psychological co-morbidities and differences in appearance. How participants coped with their negative appraisals was the greatest predictor of adaptation. Practice implications Interventions designed to help individuals reframe negative appraisals, to increase perceived manageability of the challenges of living with XXY, and to facilitate effective coping may improve adaptation among individuals with XXY.

    There is increasing recognition that organisations, particularly in key infrastructure sectors, are potentially vulnerable to climate change and extreme weather events, and require organisational responses to ensure they are resilient and adaptive. However, detailed evidence of how adaptation is facilitated, implemented and reported, particularly through legislative mechanisms is lacking. The United Kingdom Climate Change Act (2008), introduced the Adaptation Reporting Power, enabling the Government to direct so-called reporting authorities to report their climate change risks and adaptation plans. We describe the authors' unique role and experience supporting the Department for Environment, Food and Rural Affairs (Defra) during the Adaptation Reporting Power's first round. An evaluation framework, used to review the adaptation reports, is presented alongside evidence on how the process provides new insights into adaptation activities and triggered organisational change in 78% of reporting authorities, including the embedding of climate risk and adaptation issues. The role of legislative mechanisms and risk-based approaches in driving and delivering adaptation is discussed alongside future research needs, including the development of organisational maturity models to determine resilient and well adapting organisations. The Adaptation Reporting Power process provides a basis for similar initiatives in other countries, although a clear engagement strategy to ensure buy-in to the process and research on its long-term legacy, including the potential merits of voluntary approaches, is required.

    The study examines the influence of personality traits and close relationships on the coping style of women with breast cancer. A sample of 72 Italian patients receiving treatment for early stage breast cancer was recruited. Participants completed questionnaires measuring personality traits (Interpersonal Adaptation Questionnaire), interpersonal closeness (Inclusion of the Other in the Self Scale), and adjustment to cancer (Mini-Mental Adjustment to Cancer Scale). We hypothesized that diverse personality traits and degrees of closeness contribute to determine the coping styles shown by participants. Multiple regression analyses were conducted for each of the five coping styles (Helplessness/Hopelessness, Anxious Preoccupation, Avoidance, Fatalism, and Fighting Spirit) using personality traits and interpersonal closeness variables (Strength of Support Relations, and Number of Support Relations) as predictors. Women who rated high on assertiveness and social anxiety were more likely to utilize active coping strategies (Fighting Spirit). Perceived strength of relationships was predictive of using an active coping style while the number of supportive relationships did not correlate with any of the coping styles. Implications for assessment of breast cancer patients at risk for negative adaptation to the illness and the development of psychosocial interventions are discussed.

    The purpose of this qualitative study of families where a parent has cancer was to explore ways of informing the child of the parent's illness, how the child perceives the parent's emotional state, how the child copes with the parent's illness, and how this coping relates to the parent's coping and concerns for the child. Twenty-one children from 15 families and their parents were interviewed. In 13 families the mother was ill, in two the father. Children were aware of the facts of the illness, but there was limited emotional communication between the generations. The children were very observant of both the ill and the healthy parent's emotional condition. The children's observations and expressions led us to identify five coping strategies the younger generation used: Helping others, parentification, distraction, keeping it in the head, and wishful thinking. Both adaptive and destructive examples of parentification were found. Communication patterns and parental coping seemed to be highly related to the child's coping repertoire. Even though most children seemed to manage rather well, all children were strongly affected by the illness. The 'healthiest' adaptation related to factors within the family system, which has implications for the provision of help.

    Medical students studying abroad have to adapt to a new cultural environment in addition to the usual stresses of medical school. This study explored the perceived stress and coping ability of students of the New York State/American Programme, Sackler School of Medicine, Tel Aviv University, who study medicine in Israel but are expected to return to America to practice. Students were surveyed using the Ways of Coping Checklist (WCCL), Appraisal Dimension Scale (ADS) and two instruments specifically designed for the study. The results supported the view that students having difficulty adapting to their new cultural environment also have difficulty at medical school. This pattern is a negative spiral in which anxiety and depression impair cognitive performance, which leads to academic difficulties and emotional distress. Improvements in student social support and primary prevention were implemented as a result of the study. Limitations of the study are discussed.

    The study reported in this paper explores how infertile women cope with infertility using their religious and spiritual beliefs. In total, 30 infertile women affiliated to different denominations of Christianity and Islam were interviewed in the UK and Iranian fertility clinics using grounded theory. The categories which emerged included governing ones' 'Self' through gaining control of emotions, adopting religious coping strategies, and handling the burden of infertility peacefully, which all related to the core category of 'relying on a higher being'. We argue that infertile women employ a variety of religious and spiritual coping strategies which are associated with adaptive health outcomes. Further scientific inquiry is required to investigate how religion and spirituality promote adaptation to infertility.

    The aim of the study was to explore personality traits as predictors of coping with disease-related distress in patients with multiple sclerosis (MS). All patients with clinically definite MS in a city with a population of approximately 100000 were asked to complete the NEO Personality Inventory and a multidimensional coping inventory (COPE). There was an 83% response rate yielding 49 patients for the study population and 49 controls, matched for age, gender and educational level to the MS-patients, were used as comparison. Only Neuroticism correlated significantly with emotion-focused coping in both groups. Extraversion and Openness to Experience were linked to task-oriented coping strategies in normal controls but not in the MS-group. Agreeableness was associated with avoidance-oriented coping strategies only in the MS-group. Thus, the relation of certain personality characteristics to the choice of strategies for coping with the disease-related distress appear to differ from coping with stressful problems in everyday life. As dispositional characteristics may interfere with adaptive coping responses, analysis of personality traits and coping strategies could contribute while attempting to relieve the consequences of chronic disease on everyday life.

    This study examined the role of fathers caring for children with cancer. Psychological adjustment, coping, and work patterns of mothers and fathers were described. Twenty fathers of children with cancer were compared with 20 mothers of children with cancer and 20 control fathers of healthy children. Questionnaire data were collected regarding coping, parental adjustment, child adjustment, and family involvement. Fathers did not differ from mothers or control fathers in terms of psychological adjustment or coping. However, fathers of children with cancer spent more hours at work and more hours caring for children than did control fathers. Paternal adjustment was significantly related to child adjustment only when the child had cancer. Coping was related to work outside the home for fathers and adjustment for mothers. Models of family adaptation may be different for fathers and mothers. Treatment teams must attend to the unique needs of fathers.

    Many individuals with Substance Use Disorders (SUDs) have been the victims of violence and individuals with SUDs often exhibit coping skills deficits. The extent to which coping skills relate to victimization is unknown. This study evaluated the relationships between physical assault victimization types (i.e., only partner victimization, only non-partner victimization, or both partner and non-partner victimization) and emotion-focused, problem-focused, and avoidant coping among individuals in residential SUD treatment. More frequent use of problem-focused coping was associated with reduced odds of being victimized by partners and non-partners and more frequent use of avoidant coping was associated with increased odds of victimization across both partners and non-partners. These results highlight the potential value of assessing violence across relationship types and bolstering adaptive coping among individuals with SUDs. PMID:24364127

    Since the first demonstration that CRISPR-Cas systems provide bacteria and archaea with adaptive immunity against phages and plasmids, numerous studies have yielded key insights into the molecular mechanisms governing how these systems attack and degrade foreign DNA. However, the molecular mechanisms underlying the adaptation stage, in which new immunological memory is formed, have until recently represented a major unresolved question. In this Progress article, we discuss recent discoveries that have shown both how foreign DNA is identified by the CRISPR-Cas adaptation machinery and the molecular basis for its integration into the chromosome to form an immunological memory. Furthermore, we describe the roles of each of the specific CRISPR-Cas components that are involved in memory formation, and consider current models for their evolutionary origin.

    In order to identify the psychosocial factors related to the use of coping strategies by HIV-positive women diagnosed during pregnancy, four structured interviews were conducted over a period of two years with 224 HIV-positive women at antenatal clinics in Tshwane, South Africa. Two coping styles, active and avoidant coping, were assessed using an adapted version of the Brief COPE. Psychosocial variables associated with changes in coping over time were identified with mixed linear analysis. Increases in active coping were associated with decreasing levels of internalised stigma and depression, increasing self-esteem and positive social support, knowing someone who is living with HIV, being physically healthy and living above the poverty line. Increases in avoidant coping were associated with increasing internalised stigma and depression, lower levels of self-esteem, HIV-knowledge and lower levels of education. Recommendations are made for psychological support services to strengthen women’s ability to cope to enhance their health and that of their infants. PMID:23196861

    Psychopathy is a notion that has been difficult to define. The operational definition of psychopathy by Hare is one of the most commonly used in psychology and it is usually identified with the scale used to measure this type of personality, which is the Psychopathy Checklist - Revision (PCL-R). PCL-R is composed of two factors: Factor 1 describes a constellation of psychopathic traits considered by many clinicians to be basic for this type of personality, and Factor 2 describes types of behaviour indicating impulsiveness, lack of stability and antisocial lifestyle. The aim of the research was to verify a hypothesis that people with psychopathic personality disorders are characterised by high self-esteem, unconstructive strategies of planning actions and non-adaptive styles of coping with stress. The group of participants included 30 people at the age of 22-36 convicted with a legally binding sentence. Methods were: 1. The Psychopathy Checklist-Revision (PCL-R); 2. Antisocial Personality Questionnaire (APQ); 3. Coping Inventory for Stressful Situations (CISS); 4. Generalised Self-Efficacy Scale (GSES). The participants were diagnosed as psychopaths (PCL-R), and more specifically - as primary psychopaths (APQ). They revealed a grandiose sense of self-worth, increased self-control, impulsive style of functioning, perceived high self-efficacy (which might be considered as a defence mechanism). Psychopaths prefer a coping style focused on emotions and avoidance. The hypothesis was confirmed, that people with psychopathic personality disorders are characterised by high self-esteem, unconstructive strategies of planning actions and non-adaptive styles of coping with stress.

    2013-01-01

    Background This paper examines socio-economic and geographic differences in payment and payment coping mechanisms for health services in southeast Nigeria. It shows the extent to which the poor and rural dwellers disproportionally bear the burden of health care costs and offers policy recommendations for improvements. Methods Questionnaires were used to collect data from 3071 randomly selected households in six communities in southeast Nigeria using a four week recall. The sample was divided into quintiles (Q1-Q5) using a socio-economic status (SES) index as well as into geographic groups (rural, peri-urban and urban). Tabulations and logistic regression were used to determine the relationships between payment and payment coping mechanisms and key independent variables. Q1/Q5 and rural/urban ratios were the measures of equity. Results Most of the respondents used out-of-pocket spending (OOPS) and own money to pay for healthcare. There was statistically significant geographic differences in the use of own money to pay for health services indicating more use among rural dwellers. Logistic regression showed statistically significant geographic differences in the use of both OOPS and own money when controlling for the effects of potential cofounders. Conclusions This study shows statistically significant geographic differences in the use of OOPS and own money to pay for health services. Though the SES differences were not statistically significant, they showed high equity ratios indicating more use among poor and rural dwellers. The high expenditure incurred on drugs alone highlights the need for expediting pro-poor interventions like exemptions and waivers aimed at improving access to health care for the vulnerable poor and rural dwellers.

    Objectives Male sex, young age, and frequent gambling are considered as risk factors for gambling disorder (GD) and stress might be one of the triggers of gambling behavior among problem gamblers. Conversely, well-developed coping with stress might counteract gambling problems. The Proactive Coping Theory provides a promising approach for the further development of preventive and treatment measures. The objective of the study was to investigate different facets of proactive coping (PC) in young male gamblers. Methods Young men from Bavaria were recruited via the Munich citizens' registry (n = 2,588) and Facebook invitations (n = 105). In total, 173 out of 398 individuals were positively screened for frequent gambling and/or signs of related problems and completed the baseline questionnaire of the Munich Leisure-time Study. Factors investigated include gambling problems, PC, impulsiveness, social support, and psychological distress. Results Gambling problems were associated with lower levels of preventive coping as well as of adaptive reaction delay. The associations were also significant when controlled for impulsiveness and general psychological distress. Preventive coping moderated the association between social support and gambling problems. Discussion and conclusions Young men with gambling problems less frequently prevent the occurrence of stressors and more often react hasty when these occur. While the investigated group reported good social support, this factor was negatively associated with GD only among individuals with good preventive coping. Preventive coping poses a useful construct for selective prevention and treatment as it can be modified in professional interventions.

    Better understanding of the individual and environmental factors that promote adolescents' use of more or less adaptive coping strategies with mental illness stigma would inform interventions designed to bolster youth resilience. This cross-sectional study draws on data from research on adolescents' well-being after discharge from a first psychiatric hospitalization to explore the relationships between anticipated coping in reaction to a hypothetical social stigma scenario, and various factors conceptualized as 'coping resource' and 'coping vulnerability' factors. Focusing on coping strategies also identified in the companion article, we hypothesize that primary and secondary control engagement coping would relate to more coping resource and less coping vulnerability factors, and the opposite would be true for disengagement, aggression/confrontation and efforts to disconfirm stereotypes. Data were elicited from interviews with 102 adolescents within 7 days of discharge. Hypothesized coping resource factors included social resources, optimistic illness perceptions, better hospital experiences and higher self-esteem. Vulnerability factors included more previous stigma experiences, desire for concealment of treatment, more contingent self-worth, higher symptom levels and higher anticipated stress. Multivariate ordinary least squares (OLS) regression was used to analyze associations between coping strategy endorsement and correlates. Although some coping correlates 'behaved' contrary to expectations, for the most part, our hypotheses were confirmed. As expected, youth anticipating reacting to the stigmatizing situation with greater disengagement, aggression/confrontation or efforts to disconfirm stenotypes rated significantly lower on 'coping resources' such as self-esteem and higher on vulnerability factors such as symptom severity. The opposite was true for youth who anticipated exercising more primary and secondary control engagement coping. This study begins to

    Divorce is one of the more stressful and psychologically challenging experiences for spouses and whole families. After divorce, a new era begins, when it is necessary to re-adapt to life and during which hard feelings also emerge. During the process of divorce, successful emotional adaptation to the new situation is of great significance. Religion or spirituality can be a powerful source of help for an individual coping with stressful situations brought up by divorce. This study aimed to explore if and how divorcees experience the burden of divorce and along with it the relationship with God (within Catholic tradition) as a source of positive support in coping with divorce. We conducted open semi-structured interviews with 11 participants. With empirical phenomenological analysis, we built a general description of the investigated experience which entails three areas of experience: experiencing the burden of divorce, which is related to experiencing the relationship with God and the ways of spiritual coping with divorce, and experiencing the effects of religious coping with divorce. The result of this research can be used in evidence-based psychosocial (e.g. psychotherapy, counselling) and spiritual help for individuals in comprehensive care after divorce.

    The objective was to explore the psychosocial adaptation of female partners living with men with a diagnosis of either localized or metastatic prostate cancer. Semi-structured qualitative interviews were conducted with 50 women at two time points (baseline and 6 months later). The interviews examined emotions, experiences, attitudes to sexual and continence issues and treatment decision making. As part of a larger prospective observational study, demographic data and scores for depression and anxiety were collected. Initial analysis demonstrated that the group of 11 women assessed as distressed on the anxiety and depression measures described reduced coping skills and poorer adaptation after 6 months. In contrast, the 39 women in the non-distressed group reported emotional adaptation that fitted the Lazarus and Folkman pattern of coping through appraisal of the impact of the diagnosis on their partner and themselves, appraisal of coping strategies and reappraisal of the situation. A surprise finding was the high level of resilience displayed by majority of these women. Results suggest that a psychosocial intervention could strengthen healthy adaptation and provide better coping skills for distressed couples.

    To examine distress and coping self-efficacy in inpatient oncology nurses. 
. Cross-sectional survey design.
. Oncology Nursing Society (ONS) chapter meetings and Hunter-Bellevue School of Nursing, both in New York, New York, as well as social media.
. 163 oncology nurses who work with an inpatient adult population.
. Participants were recruited through the ONS New York, New York, area chapter meetings, Hunter College, and ONS Facebook pages. An adapted Nurse Distress Thermometer (NDT) measured distress levels. The Occupational Coping Self-Efficacy Questionnaire for Nurses (OCSE-N) used a Likert-type scale to measure coping self-efficacy. Open-ended questions elicited additional perceptions of nurse respondents. 
. Descriptive statistics summarized sample demographics. A Pearson correlation between distress levels and coping self-efficacy scores was calculated. Low, normal, and high coping scores were compared to mean distress levels. 
. Survey participants showed high levels of distress, with a mean NDT score of 8.06. Those with higher coping self-efficacy scores reported less distress. A moderate, negative correlation was shown, with a statistically significant Pearson coefficient of -0.371. Responses to the open-ended questions revealed common stressors and pointed to solutions that institutions might implement to support nurses.
. Because coping self-efficacy related to lower distress levels in inpatient oncology nurses, institutional-level support for oncology nurses should be provided. 
. Interventions aimed at coping self-efficacy may prepare oncology nurses to cope better with their professional demands. Future research should explore how nurse distress affects patients.

  3. Psychotic symptoms, functioning and coping in adolescents with mental illness

    Background Psychotic symptoms in the context of psychiatric disorders are associated with poor functional outcomes. Environmental stressors are important in the development of psychosis; however, distress may only be pathogenic when it exceeds an individual’s ability to cope with it. Therefore, one interesting factor regarding poor functional outcomes in patients with psychotic symptoms may be poor coping. This paper aimed to address the question whether 1) psychotic symptoms are associated with poorer functioning and 2) whether poor coping moderated the association. Methods In a clinical case-clinical control study of 106 newly-referred adolescent patients with non-psychotic psychiatric disorders, coping was investigated using the Adolescents Coping Scale. Severity of impairment in socio-occupational functioning was assessed with the Children’s Global Assessment Scale. Results Patients with non-psychotic psychiatric disorders and additional psychotic symptoms (N = 50) had poorer functioning and were more likely to use avoidance-oriented coping compared to patients with non-psychotic psychiatric disorders without psychotic symptoms (N = 56). No differences were found with respect to approach-oriented coping. When stratifying for poor/good coping, only those adolescent patients with psychotic symptoms who applied poor coping (i.e. less use of approach-oriented coping styles [OR 0.24, p < 0.015] and more use of avoidance-oriented coping [OR 0.23, p < 0.034]) had poorer functioning. However, these interactions were not significant. Conclusions Non-adaptive coping and poorer functioning were more often present in adolescents with non-psychotic psychiatric disorders and additional psychotic symptoms. Due to small subgroups, our analyses could not give definitive conclusions about the question whether coping moderated the association between psychotic symptoms and functioning. Improvement of coping skills may form an important target for intervention

  4. Examining the relationship between coping strategies and suicidal desire in a sample of United States military personnel.

    Suicidal desire in the military has been previously examined through the lens of the Interpersonal-Psychological Theory of Suicide (IPTS). However, no research has examined the impact of specific coping strategies on perceived burdensomeness, thwarted belongingness, and suicidal ideation in a large population of individuals serving in the US military. Furthermore, the factor structure of previously utilized coping clusters did not apply to our sample of military personnel. Therefore, we found a three-factor solution to be tested in this sample. We hypothesized that specific types of coping behavior clusters (Adaptive and Maladaptive) would predict both IPTS constructs and suicidal ideation. Results indicated that Adaptive and Maladaptive coping clusters predicted the IPTS constructs in the hypothesized directions. However, only the Maladaptive cluster predicted suicidal ideation. These findings implicate the need for further research and suicide prevention efforts focusing on coping strategies, specifically those that are maladaptive in nature, in relation to suicidal ideation in military members.

    Recent research indicates that young adult college students experience increased levels of depression, anxiety, and stress. It is less clear what strategies college health care providers might use to assist students in decreasing these mental health concerns. In this paper, we examine the relative importance of coping style, life satisfaction, and selected demographics in predicting undergraduates' depression, anxiety, and stress. A total of 508 full-time undergraduate students aged 18-24 years completed the study measures and a short demographics information questionnaire. Coping strategies and life satisfaction were assessed using the Brief COPE Inventory and an adapted version of the Brief Students' Multidimensional Life Satisfaction Scale. Depression, anxiety, and stress were measured using the Depression Anxiety and Stress Scale-21 (DASS-21). Multiple regression analyses were used to examine the relative influence of each of the independent variables on depression, anxiety, and stress. Maladaptive coping was the main predictor of depression, anxiety, and stress. Adaptive coping was not a significant predictor of any of the three outcome variables. Reducing maladaptive coping behaviors may have the most positive impact on reducing depression, anxiety, and stress in this population.

    Dyadic coping strategies may play a pivotal role in relationship satisfaction and explain why some couples adapt positively to the challenges associated with raising a child with ASD and others do not. Survey data from 127 caregivers of a child with ASD were used in generalized estimating equation analyses to investigate the factors associated with relationship satisfaction, including socio-demographics, parenting stress and dyadic coping. Results showed that over two-thirds of the sample reported satisfaction, which was associated with low parenting stress, increased use of positive and decreased use of negative dyadic coping strategies. Positive dyadic coping was found to have a greater influence than negative dyadic coping, supporting a strengths-based approach to interventions promoting family resilience.

    This study tested how poverty-related stress (PRS), psychological distress, and responses to stress predicted future effortful coping and involuntary stress responses one year later. In addition, we explored age, sex, ethnicity, and parental influences on responses to stress over time. Hierarchical linear modeling analyses conducted with 98 low-income families (300 family members: 136 adults, 82 school-aged children, 82 adolescents) revealed that primary control coping, secondary control coping, disengagement, involuntary engagement, and involuntary disengagement each significantly predicted future use of that response. Primary and secondary control coping also predicted less maladaptive future responses to stress, while involuntary responses to stress undermined the development of adaptive responding. Age, sex, and interactions among PRS and prior coping were also found to predict certain responses to stress. In addition, child subgroup analyses demonstrate the importance of parental modeling of coping and involuntary stress responses, and warmth/nurturance and monitoring practices. Results are discussed with regard to the implications for preventive interventions with families in poverty.

  8. Adaptive livelihood strategies for coping with water scarcity in the drylands of central Tanzania

    In this paper, it is argued that local knowledge for adapting to water scarcity is important for integrated resource management by taking into consideration both the natural and social constraints in a particular setting based on accumulated experience. The paper examines the relevance of local knowledge in sustaining agricultural production in the semiarid areas of central Tanzania. The paper specifically focuses on how water scarcity, as the major limiting factor, is addressed in the study area using local knowledge to sustain livelihoods of its people. The study was conducted in four villages; Mzula, Ilolo, Chanhumba and Ngahelezi, situation in Mvumi Division in Dodoma Region. The study mainly employed qualitative data collection techniques. Participatory methods provided a means of exploring perceptions and gaining deeper insights regarding natural resource utilization in terms of problems and opportunities. The main data sources drawn upon in this study were documentation, group interviews and field observations. Group interviews involved discussions with a group of 6-12 people selected on the basis of gender, age and socio-economic groups. Data analysis entailed structural and content analysis within the adaptive livelihood framework in relation to management of water scarcity using local knowledge. The findings confirm that rainfall is the main limiting factor for agricultural activities in the drylands of Central Tanzania. As such, local communities have developed, through time, indigenous knowledge to cope with such environments utilizing seasonality and diversity of landscapes. Use of this local knowledge is therefore effective in managing water scarcity by ensuring a continuous production of crops throughout the year. This practice implies increased food availability and accessibility through sales of such agricultural products. Local innovations for water management, such as cultivation in sandy rivers, appear to be very important means of accessing

    Patient death is an event that all health care workers will face at some point. Beyond the family, the greatest emotional strain is on people who work directly with the patient and family. Bereavement overload occurs after multiple losses without time for normal grief in between. To investigate bereavement overload, its effects and related coping mechanisms of personnel working in adult medical wards. Four adult medical wards at National District Hospital, Bloemfontein. An analytical cross-sectional study design was performed with the aid of an intervieweradministered questionnaire. The target population included health care providers (13 doctors and 20 nurses), eight final-year medical students, and four administrative staff working in thefour adult medical wards at National District Hospital, during August to October 2016. Half (48.9%) of the 45 participants reported bereavement overload. None of the medical students reported bereavement overload compared to 60.0% of nurses, 75.0% of administrative staff and 53.9% of doctors. Nearly two-thirds (64.5%, n = 29) stated that they suffered from compassion fatigue. The majority of participants (62.2%) used only positive coping mechanisms. The use of negative coping mechanisms correlated directly with a longer duration in the medical field. With a 49% prevalence of bereavement overload, it is important that support systems are in place to prevent the effects of negative coping mechanisms. The desirable outcome is that health care providers, who suffer from bereavement overload, experience compassion satisfaction and become more dedicated to the patients' well-being without expense to themselves.

    The aim of this review is to examine the literature related to the sources of stress, coping mechanisms and interventions to support undergraduate nursing and midwifery students to cope with stress during their undergraduate education. Integrative literature review. The databases CINAHL, PubMed and PsycINFO were searched for articles published between 2010 and 2016. Search terms in various combinations were used for example; student nurse, student midwife, undergraduate, stress, coping and interventions. An integrative review based on Whittemore and Knafl's approach was used to conduct the review. The search generated 25 articles that met the inclusion criteria. The key sources of stress emanated from clinical, academic and financial issues but predominantly from the clinical environment. Students used a variety of coping strategies, both adaptive and maladaptive. These appear to be influenced by their past and present circumstances such as, their needs, what was at stake and their options for coping. Interventions for student nurses/midwives to cope with stress were varied and in the early stages of development. Mindfulness showed some promising positive results. Interventions focussed on the individual level excluding the wider social context or organisation level. Stress is pervasive in all aspects of undergraduate nursing and midwifery education. Nursing and midwifery educators need to be aware of this impact and provide appropriate support to students in both the clinical and academic environments. Further research is needed to capture the experience of stress from the students' perspective as well as the barriers and facilitators to supporting students from the preceptors'/mentors' perspectives. Finally, more intervention studies are needed to identify and compare what interventions are effective in supporting students to cope with stress during their undergraduate education.

    Nursing is acknowledged as a stressful occupation, and the negative impact of high stress levels have been widely researched. Less attention has been paid to methods for coping with stress. The researchers conducted a study to explore and identify how nurses cope with work-related stress away from their work environments. Six focus groups were conducted with 38 nurses, including nursing directors, nurse unit managers, and ward nurses from a wide range of clinical areas. From the interview material, 11 coping strategies were identified: drinking alcohol, smoking, using the staff social club, using social networking websites, exercising, family activities, home-based activities, outdoor activities, avoiding people, displacement, and sleep. Although several adaptive strategies appear in this list (e.g., exercising, home-based activities), some nurses were using unhealthy behaviours to cope with work-related stress (e.g., drinking alcohol, smoking, displacement). This study clearly demonstrates the value of using qualitative approaches to understanding how nurses cope with stress. Knowledge produced locally, such as that generated for the hospital in this study, should serve as the foundation for organisational strategies to enhance the health of nurses.

    In a cross-sectional survey among 213 patients with multiple sclerosis, we intended to analyze their resources of hope, orientation, and inspiration in life, and how these resources are related to health-associated variables, adaptive coping strategies, and life satisfaction. Resources were categorized as Faith (10 %), Family (22 %), Other sources (16 %), and No answer (53 %). These non-respondents were predominantly neither religious nor spiritual (70 % R-S-). Although R-S- persons are a heterogeneous group with varying existential interest, they did not significantly differ from their spiritual/religious counterparts with respect to physical and mental health or life satisfaction, but for an adaptive Reappraisal strategy and Gratitude/Awe.

    Aggression is one of the chief determinants of caregiver burden in severe mental illnesses. Clinical and treatment implications of aggression in mental illness are predominantly studied in perspectives of mental health care professionals. Coping style of caregivers towards aggression of persons with mental illness is understudied. So we studied coping strategies used by caregivers of patients with severe mental illness towards aggressive behaviors of patients and relationship between aggressive behavior and coping strategies. We assessed two hundreds and seventy caregivers of patients with severe mental illness attending outpatient psychiatry department using Modified Overt Aggression Scale and the Ways of Coping Scale - revised. 95.6% of the caregivers perceived verbal aggression followed by aggression against property (67%), auto aggression (33.7%) and physical aggression (25.6%). The study revealed that adaptive coping strategies - planful problem solving and seeking social support were used by 40% each of caregivers to deal with aggressive behavior. Only 4.4% of caregivers resorted to escape avoidance which is maladaptive coping strategy. Though adaptive strategies were used by caregivers these were not used in appropriate situations. Physical aggression and aggression against property were not significantly associated with planful problem solving (r = 0.105; p = 0.08 and r = 0.110; p = 0.07 respectively). But verbal aggression, aggression against property and physical aggression were associated with escape avoidance (r = 0.152; p = 0.01 and r = 0.168; p = 0.01 and r = 0.23; p = <0.001 respectively). The study concluded that coping in caregivers of severe mental illness is maladaptive with respect to aggression. Coping skills training would play a major role to address this issue.

    Studies are lacking that analyze how clinically referred adolescents and healthy adolescents cope with everyday stressors. Clinically referred adolescents from three problematic domains (diverse disorders including delinquency, drug abuse, and depression) were compared to healthy adolescents using the Coping Across Situations Questionnaire (Seiffge-Krenke, 1995) and a short version of the Youth Self-Report (Achenbach, 1991). The different clinical groups (n = 469) showed unique patterns concerning their coping styles. The group of depressed youth altogether showed lower coping activities. The youth from institutions for drug abusive youth used more dysfunctional coping. The adolescents from youth welfare services (diverse disorders including delinquency) were more active in both dysfunctional and functional coping than the other two clinically referred groups. The control group showed more functional and less dysfunctional coping. The clinically referred adolescents did not differentiate in their coping behavior, depending on the type of stressor. Gender effects were apparent, albeit negligible. Clinically referred youth are unable to adapt their coping behavior according to the given situation.

    Among aging parents (mean age = 65, N = 139) of adults with developmental disabilities, we examined the effectiveness of multiple forms of coping with caregiver burden. As expected, accommodative strategies of adapting to stress (secondary engagement), used frequently in later life, buffered the impact of caregiver burden, whereas disengagement and distraction strategies exacerbated the effects of burden on depression symptoms. Most effects were similar for mothers and fathers, and all coping strategies, including active strategies to reduce stress (primary engagement), had greater effects for the parents with co-resident children. Vulnerability to caregiver burden was greatest when the aging parents with co-resident children used disengagement and distraction coping, but those who used engagement coping were resilient.

    Fear of the dentist and dental treatment is a common problem. It can cause treatment difficulties for the practitioner, as well as severe consequences for the patient. As is known, the level of stress can be evaluated thought electrodermal activity, cortisol measure in saliva, or indirectly by psychometric tests. The present study examined the psychological influence of dental interventions on the child as well as coping patterns used for stress diminution. We examined two matched groups of patients: a) children with orthodontic problems (anomalies in shape, position and function of dentomaxillofacial structures) (N = 31, mean age 10.3 ± 2.02) years; and b) children with ordinary dental problems (N = 31, mean age 10.3 ± 2.4 years). As psychometric instruments, we used: 45 items Sarason's scale for anxiety, 20 items simple Stress - test adapted for children, as well as A - cope test for evaluation coping patterns. Obtained scores confirmed the presence of moderate anxiety in both groups as well as moderate stress level. For Sarason's test obtained scores for the group with dental problems are 20.63 ± 8.37 (from max 45); and for Stress test 7.63 ± 3.45 (from max 20); for the orthodontic group obtained scores are 18.66 ± 6.85 for Sarason's test, while for the Stress test were 7.76 ± 3.78. One way ANOVA confirmed a significant difference in values of obtained scores related to the age and gender. Calculated Student t - test shows non-significant differences in obtained test results for both groups of examinees. Coping mechanisms evaluated by A - cope test shows that in both groups the most important patterns used for stress relief are: developing self-reliance and optimism; avoiding problems and engaging in demanding activity. This study confirmed that moderate stress level and anxiety are present in both groups of patients (orthodontic and dental). Obtained scores are depending on gender and age. As more used coping patterns in both groups are developing self

    Stress experience modulates behavior, metabolism, and energy expenditure of organisms. One molecular hallmark of an acute stress response is a rapid induction of immediate early genes (IEGs) such as c-Fos and Egr family members. IEG transcription in neurons is mediated by the neuronal activity-driven gene regulator serum response factor (SRF). We show a first role of SRF in immediate and long-lasting acute restraint stress (AS) responses. For this, we employed a standardized mouse phenotyping protocol at the German Mouse Clinic (GMC) including behavioral, metabolic, and cardiologic tests as well as gene expression profiling to analyze the consequences of forebrain-specific SRF deletion in mice exposed to AS. Adult mice with an SRF deletion in glutamatergic neurons (Srf; CaMKIIa-CreERT2 ) showed hyperactivity, decreased anxiety, and impaired working memory. In response to restraint AS, instant stress reactivity including locomotor behavior and corticosterone induction was impaired in Srf mutant mice. Interestingly, even several weeks after previous AS exposure, SRF-deficient mice showed long-lasting AS-associated changes including altered locomotion, metabolism, energy expenditure, and cardiovascular changes. This suggests a requirement of SRF for mediating long-term stress coping mechanisms in wild-type mice. SRF ablation decreased AS-mediated IEG induction and activity of the actin severing protein cofilin. In summary, our data suggest an SRF function in immediate AS reactions and long-term post-stress-associated coping mechanisms.

    Three studies tested the hypothesis that the relation between perceived racial discrimination and substance use reported in previous research is moderated by use of substances as a coping mechanism. Studies 1 and 2 were experimental studies of African American adolescents' and young adults' reactions to a discrimination experience. Results revealed that those who endorsed substance use-as-coping reported more willingness to use substances after experiencing discrimination. Study 3 was a prospective study of the relation between perceived discrimination and substance use over an 8-year period in African American adolescents. Results demonstrated that discrimination is associated with increases in substance use, but only among adolescents who endorse substance use-as-coping. Together, these three studies provide evidence that experiencing discrimination has both short- and long-term detrimental effects on African Americans' substance use, but significantly more so for those who adopt a pattern of using substances as a coping mechanism.

    As the second biggest animal group in mammals, Chiroptera (bats) demonstrates many unique adaptive features in terms of flight, echolocation, auditory acuity, feeding habit, hibernation and immune defense, providing an excellent system for understanding the molecular basis of how organisms adapt to the living environments encountered. In this review, we summarize the researches on the molecular mechanism of the adaptive evolution of Chiroptera, especially the recent researches at the genome levels, suggesting a far more complex evolutionary pattern and functional diversity than previously thought. In the future, along with the increasing numbers of Chiroptera species genomes available, new evolutionary patterns and functional divergence will be revealed, which can promote the further understanding of this animal group and the molecular mechanism of adaptive evolution.

    2013-08-01

    The eating disorder literature has sought to understand the role of comorbid psychiatric diagnoses and coping in relation to eating disorders. The present research extends these findings by studying the relationships among depression, coping, and the entire continuum of disordered eating behaviors, with an emphasis on subthreshold eating disorders. 109 undergraduate females completed questionnaires to assess disordered eating symptoms, depressive symptoms, and the use of active and avoidant coping mechanisms. Hypotheses were tested using bivariate linear regression and multivariate linear regression. Results indicated that depression was a significant predictor of disordered eating symptoms after controlling for relationships between depression and coping. Although avoidant coping was positively associated with disordered eating, it was not a significant predictor after controlling for depression and coping. Previous research has found associations between depression and diagnosable eating disorders, and this research extends those findings to the entire continuum of disordered eating. Future research should continue to investigate the predictors and correlates of the disordered eating continuum using more diverse samples. Testing for mediation and moderation among these variables may also be a fruitful area of investigation. Published by Elsevier Ltd.

  4. Stressors, coping, and social supports of adolescent mothers.

    Panzarine, S

    1986-05-01

    This report describes the perceived stressors, coping strategies, and social supports of a group of adolescent mothers during their first month at home after delivery. In addition to concerns about the baby and the limitations imposed by motherhood, many of the young mothers considered their interpersonal relationships as problematic. Findings suggest that the puerperium was not a time of major distress for most of these young women. Factors contributing to a relatively smooth transition to motherhood were the adolescent's use of anticipatory coping prior to the birth, their extensive reliance on family support once at home, and their past experience with childcare. Sharing childcare with the family was an important component of the support received by these adolescents, and it is suggested that the adolescent's mobilization of social supports may be essential to ther adaptation to motherhood. Professionals were infrequently mentioned as sources of support even though a majority of the sample participated in special adolescent maternity programs. Finally, findings also suggest that problem-focused coping was used more often when dealing with concrete stressors, while emotion-focused coping was used more in response to interpersonal problems.

     Dispositional optimism is a personal resource that determines the coping style and adaptive response to chronic diseases. The aim of this study was to assess the correlations between dispositional optimism and coping strategies in patients with recent kidney transplantation and evaluate the differences in the use of coping strategies in accordance with the level of dispositional optimism.  Patients who were hospitalised in the nephrology department were selected consecutively after kidney transplantation was performed. The evaluation instruments were the Life Orientation Test-Revised, and the Coping Strategies Inventory. The data were analysed with central tendency measures, correlation analyses and means were compared using Student’s t-test.   66 patients with a kidney transplant participated in the study. The coping styles that characterised patients with a recent kidney transplantation were Social withdrawal and Problem avoidance. Correlations between dispositional optimism and coping strategies were significant in a positive direction in Problem-solving (p<.05) and Cognitive restructuring (p<.01), and inversely with Self-criticism (p<.05). Differences in dispositional optimism created significant differences in the Self-Criticism dimension (t=2.58; p<.01).  Dispositional optimism scores provide differences in coping responses after kidney transplantation. Moreover, coping strategies may influence the patient’s perception of emotional wellbeing after kidney transplantation.

    Terror exposure has become commonplace in Israel, with civilians needing to develop appropriate coping mechanisms. This study investigated coping mechanisms of those who are able to return to leisure activity at sites of previous terror attacks. A specially designed questionnaire, exploring knowledge of the terror event, previous terror exposure, coping mechanisms, state of anxiety, and mood, was administered to 93 restaurant attendees at sites of well-known recent terror attacks (2001-2005). Most respondents were aware of the previous terror attack (92.3%) and most reported no fear at revisiting (70.3%), with 20.9% reporting some anxiety and 5.5% reporting moderate or severe anxiety. Sixty percent reported that they have no fear that a terror attack will reoccur at the same place. Some (27.7%) reported change in practices or decrease in one or more activity, especially use of public transport (18%). The most helpful reported resource for facilitating stress coping following a suicide bombing was to "call or be in touch with friends or relatives," and least helpful was "medicines." Over half of respondents (53%) reported that the current security climate affected their mood. Older individuals and females were more affected by terror events. Study observations confirm that resilience develops in the general population in response to ongoing terror attacks. Response to terror is heterogeneous with a range of coping mechanisms expressed.

    The effects of mental illness stigma on adolescents receiving psychiatric treatment may largely be determined by their coping strategies. Yet, little is known about adolescents' use of stigma-coping strategies, or how helpful these are for addressing stigma-related stress. This study explores how adolescents discharged from psychiatric hospitalization anticipate coping with a hypothetical social stigma event related to hospitalization. We examine how well anticipated coping strategies predict adolescents' self-stigma ratings following 6 months. To evaluate the direction of causality, the reverse order of effects, the influence of self-stigma on coping strategies, is also assessed. A voluntary sample of 80 adolescents participated in two face-to-face interviews that assessed coping and self-stigma. Anticipated (baseline) and actual (follow-up) coping strategies were measured with a modified Response to Stress Questionnaire (primary and secondary control engagement coping, disengagement) and two stigma-specific strategies developed for this study (disconfirming stereotypes and aggression/confrontation). Relationships between anticipated coping strategies and self-stigma were assessed with ordinary least squares (OLS) regression; multivariate general linear modeling (GLM) and structural equation modeling (SEM) explored the reverse associations. Youth reporting higher self-stigma ratings at follow-up anticipated using more disengagement and effort to disconfirm stereotypes and less secondary control engagement coping at baseline. Anticipated use of secondary control engagement coping was uniquely significant in predicting participants' self-stigma when controlling for baseline self-stigma. At the same time, higher baseline self-stigma ratings predicted less adaptive coping (disengagement and effort to disconfirm stereotypes) at follow-up. The results point to the particular importance of secondary control engagement coping for helping to mitigate the impact of peer

    The aim of this study was to determine the associations between health locus of control (LoC), causal attributions and coping in tumour patients prior to autologous peripheral blood stem cell transplantation. Patients completed the Questionnaire of Health Related Control Expectancies, the Questionnaire of Personal Illness Causes (QPIC), and the Freiburg Questionnaire of Coping with Illness. A total of 126 patients (45% women; 54% suffering from a multiple myeloma, 29% from non-Hodgkin lymphomas, and 17% from other malignancies) participated in the study. Cluster analysis yielded four LoC clusters: 'fatalistic external', 'powerful others', 'yeah-sayer' and 'double external'. Self-blaming QPIC items were positively correlated with depressive coping, and 'fate or destiny' attributions with religious coping (P<0.001). The highest scores were found for 'active coping' in the LoC clusters 'powerful others' and 'yeah-sayer'. External LoC and an active coping style prevail before undergoing autologous peripheral blood stem cell transplantation, whereas the depressive coping is less frequent, associated with self-blaming causal attributions. Health beliefs include causal and control attributions, which can improve or impair the patient's adjustment. A mixture between internal and external attributions seems to be most adaptive.

    This study examines the differential effects of adult and childhood physical and psychological abuse, abuse-specific coping, and psychological adjustment in battered women seeking emergency shelter. Multivariate regression analyses confirmed the devastating impact of psychological abuse (childhood and concurrent) on battered women's adjustment. The results corroborated prior research suggesting a cumulative vulnerability to psychological victimization in a substantial proportion of residents. Unexpectedly, frequency of physical violence was unrelated to women's distress. The study argues that modes of coping traditionally considered adaptive (e.g., engaged, proactive) may be unsafe for battered women and children. The multifaceted nature of survivors' coping choices is discussed.

    While diving, seals are exposed to apnea-induced hypoxemia and repetitive cycles of ischemia/reperfusion. While on land, seals experience sleep apnea, as well as prolonged periods of food and water deprivation. Prolonged fasting, sleep apnea, hypoxemia and ischemia/reperfusion increase oxidant production and oxidative stress in terrestrial mammals. In seals, however, neither prolonged fasting nor apnea-induced hypoxemia or ischemia/reperfusion increase systemic or local oxidative damage. The strategies seals evolved to cope with increased oxidant production are reviewed in the present manuscript. Among these strategies, high antioxidant capacity and the oxidant-mediated activation of hormetic responses against hypoxia and oxidative stress are discussed. In addition to expanding our knowledge of the evolution of antioxidant defenses and adaptive responses to oxidative stress, understanding the mechanisms that allow adapted mammals to avoid oxidative damage has the potential to advance our knowledge of oxidative stress-induced pathologies and to enhance the translative value of biomedical therapies in the long term.

    We examine the wider social knowledge domain that complements technical and environmental knowledge in enabling adaptive practices through two case studies in Tanzania. We are concerned with knowledge production that is shaped by gendered exclusion from the main thrusts of planned adaptation, in the practice of irrigation in a dryland village and the adoption of fast-maturing seed varieties in a highland village. The findings draw on data from a household survey, community workshops, and key informant interviews. The largest challenge to effective adaptation is a lack of access to the social networks and institutions that allocate resources needed for adaptation. Results demonstrate the social differentiation of local knowledge, and how it is entwined with adaptive practices that emerge in relation to gendered mechanisms of access. We conclude that community-based adaptation can learn from engaging the broader social knowledge base in evaluating priorities for coping with greater climate variability.

    Bipolar disorder (BPD) is a common condition associated with significant morbidity and reduced quality of life. In addition to challenges caused by their mood symptoms, parents affected with BPD harbor concerns about the mental health of their children. Among adult parents who perceive themselves to have BPD, this study aims to examine participants' coping methods; identify predictors of adaptation; assess parental perceptions of risks for mood disorders among their children; and describe the relationships among illness appraisals, coping, adaptation to one's own illness, and perceived risk to one's children. Parents who self-identified as having BPD completed a web-based survey that assessed dispositional optimism, coping, perceived illness severity, perceived etiology of BPD, perceived risk to offspring, and adaptation to BPD. Participants had at least one unaffected child who was 30 years of age or below. 266 parents were included in the analysis. 87% of parents endorsed a "somewhat greater" or "much greater" risk for mood disorders in one's child(ren) than someone without a family history. Endorsing a genetic/familial etiology to BPD was positively correlated with perceived risk for mood disorders in children (rs = .3, p < 0.01) and active coping with BDP (r = .2, p < 0.01). Increased active coping (β = 0.4, p < 0.001) and dispositional optimism (β = 0.3, p < 0.001) were positively associated with better adaptation, while using denial coping was negatively associated with adaptation (β = -0.3, p < 0.001). The variables explained 55.2% of the variance in adaptation (F = 73.2, p < 0.001). Coping mediated the effect of perceived illness severity on adaptation. These data inform studies of interventions that extend beyond symptom management and aim to improve the psychological wellbeing of parents with BPD. Interventions targeted at illness perceptions and those aimed at enhancing coping should be studied for

    An overdenture is a complete denture supported by both soft tissue and a few remaining natural teeth. The purpose of this study was to analyze the stress distribution of the teeth and supporting structures when various type of coping under overdenture was applied. The analysis was conducted by using the finite element method and changing the condition such as the direction of the load, the shape of coping on the abutment: The model included overdenture copings, abutment tooth and supporting structures. The results of analysis were as follows: 1. The short dome coping showed well distribution of stress. 2. The dome shaped design produced higher stress distribution than square and inclined plane design. 3. As the height of copings on the abutment was increased, the displacements increased. 4. The magnitude and direction of the abutment displacements were influenced by the direction of load application.

    It is accepted among scholars that coping changes as people mature during adolescence, but little is known about the relationship between maturity and coping. The purpose of this paper was to assess a model, which included dispositional coping, coping effectiveness, and cognitive social maturity. We predicted that cognitive social maturity would have a direct effect on coping effectiveness, and also an indirect impact via dispositional coping. Two hundred forty-five adolescent athletes completed measures of dispositional coping, coping effectiveness, and cognitive social maturity, which has three dimensions: conscientiousness, peer influence on behavior, and rule following. Using structural equation modeling, we found support for our model, suggesting that coping is related to cognitive social maturity. This information can be used to influence the content of coping interventions for adolescents of different maturational levels.

    We report an adaptive mechanical-wetting lens actuated by ferrofluids. The ferrofluids works like a piston to pump liquids in and out from the lens chamber, which in turn reshapes the lens curvature and changes the focal length. Both positive and negative lenses are demonstrated experimentally. The ferrofluid-actuated mechanical-wetting lens exhibits some attractive features, such as high resolution, fast response time, low power consumption, simple structure and electronic control, weak gravity effect, and low cost. Its potential applications in medical imaging, surveillance, and commercial electronics are foreseeable.

    Purpose The purpose of this paper is to describe coping practices used by older women during preclinical disability. Design This paper was derived from qualitative data gathered during a larger multimethod longitudinal study. Twelve women (60 to 80 years of age) participated in baseline functional performance measures and then repeated in-depth interviews and participant observations over 18 months. Methods A hermeneutic approach was used to interpret the in-depth interviews, participant observations, and field notes using three interrelated processes of thematic, exemplar, and identification of paradigm cases to identify coping practices. Findings Women coped with functional decline, such as difficulty getting up from the floor, in many different ways. Coping practices were grouped into five themes: resist, adapt, substitute, endure, and eliminate. Clinical Relevance These findings suggest that nurses need to realize outward appearances may mask the level of effort required for older women to complete daily activities. PMID:21091627

    Experience of occupational stress is inevitably involved in the execution of any type of work. Stress has an adaptive value. It motivates the individual to attend to the task and get rid of the tension or demand the unattended task produced. The study was planned to investigate the differences between executives and shop floor workers on occupational stress, mental health, job satisfaction and coping. A random sample of 200 executives and shop floor employees collected from Nuclear Fuel Complex of Hyderabad City. A well developed sub-scales of Occupational Stress indicator like Mental Health, and Coping behavior were used in the present study. The shop floor workers experiencing more job stress and lower mental health. But these two groups did not differ in their coping behaviour. The executives are better with work home balance.

    The aim of this study was to explore the level of posttraumatic growth (PTG) and its relationship to the level of stress coping strategies, spirituality and social support among rheumatoid arthritis (RA) patients (n = 250). The level of PTG was measured by the Polish adaptation of the Posttraumatic Growth Inventory. Stress coping strategies were evaluated by the Polish adaptation of the Mini-COPE Inventory. Spirituality was measured by the Self-Description Questionnaire. Social support was assessed with the Berlin Social Support Scales. Stress coping strategies (return to religion, acceptance), spirituality and social support (need for support) were significantly related to the level of PTG among participants. Despite evidence of a beneficial relationship between PTG and the course of RA, little empirical attention has been paid to the factors associated with PTG among this patient group. Given the substantial health-related benefits associated with PTG among RA patients, it is important to further explore the phenomena of PTG among RA patients.

    2008-01-01

    SUMMARY OF RECENT ADVANCES Life on Earth has always existed in the flux of ionizing radiation. However, fungi seem to interact with the ionizing radiation differently from other Earth’s inhabitants. Recent data show that melanized fungal species like those from Chernobyl’s reactor respond to ionizing radiation with enhanced growth. Fungi colonize space stations and adapt morphologically to extreme conditions. Radiation exposure causes upregulation of many key genes, and an inducible microhomology-mediated recombination pathway could be a potential mechanism of adaptive evolution in eukaryotes. The discovery of melanized organisms in high radiation environments, the space stations, Antarctic mountains, and in the reactor cooling water combined with phenomenon of ‘radiotropism’ raises the tantalizing possibility that melanins have functions analogous to other energy harvesting pigments such as chlorophylls.

    2013-01-01

    A burgeoning body of cultural coping research has begun to identify the prevalence and the functional importance of collective coping behaviors among culturally diverse populations in North America and internationally. These emerging findings are highly significant as they evidence culture's impacts on the stress-coping process via collectivistic values and orientation. They provide a critical counterpoint to the prevailing Western, individualistic stress and coping paradigm. However, current research and understanding about collective coping appear to be piecemeal and not well integrated. To address this issue, this review attempts to comprehensively survey, summarize, and evaluate existing research related to collective coping and its implications for coping research with culturally diverse populations from multiple domains. Specifically, this paper reviews relevant research and knowledge on collective coping in terms of: (a) operational definitions; (b) theories; (c) empirical evidence based on studies of specific cultural groups and broad cultural values/dimensions; (d) measurements; and (e) implications for future cultural coping research. Overall, collective coping behaviors are conceived as a product of the communal/relational norms and values of a cultural group across studies. They also encompass a wide array of stress responses ranging from value-driven to interpersonally based to culturally conditioned emotional/cognitive to religion- and spirituality-grounded coping strategies. In addition, this review highlights: (a) the relevance and the potential of cultural coping theories to guide future collective coping research; (b) growing evidence for the prominence of collective coping behaviors particularly among Asian nationals, Asian Americans/Canadians and African Americans/Canadians; (c) preference for collective coping behaviors as a function of collectivism and interdependent cultural value and orientation; and (d) six cultural coping scales.

    This work describes the self-calibration of a high-precision open-loop mechanism. The self-calibration method is applied to a mechanical shutter for space applications, which was launched onboard the ESA-ROSETTA mission (launch: 2 March 2004). It is based on an adaptive 'model reference' and a 'randomised' search method which may be generalised to applications in which high performance and functionality are strongly interconnected. The method makes use of an adaptive 'model-reference' control approach [K.J. Astrom, B. Wittenmark, On self-tuning regulators Automatica 9 (1973) 185-199 [16]; K.J.

    Some studies find that parents of children with Down's syndrome may experience symptoms of depression, while other studies find that parents adapt well. This study aimed to clarify this variability in adaptive strength by investigating a stress-coping model to explain depressive symptoms and positive affect. Questionnaires were completed by 553 parents of children (aged 0-18) with Down's syndrome, containing measures of goal disturbance, cognitive coping, social support, partner bonding, and coping self-efficacy. Different models for positive affect and depressive symptoms were found. The coping strategies of self-blame and rumination were positively related to depressive symptoms, and positive reappraisal was positively related to positive affect. Partner bonding characteristics played relevant roles in both models, as did coping self-efficacy and goal disturbance. Social support seemed mainly relevant in explaining positive affect. Different psychological factors were related to depressive symptoms and positive affect in parents of children with Down's syndrome. Implications are discussed.

    This paper analyzes the fast and slow mechanisms of adaptation through a study of latencies and amplitudes on ABR recorded at high stimulation rates using the randomized stimulation and averaging (RSA) technique. The RSA technique allows a separate processing of auditory responses, and is used, in this study, to categorize responses according to the interstimulus interval (ISI) of their preceding stimulus. The fast and slow mechanisms of adaptation are analyzed by the separated responses methodology, whose underlying principles and mathematical basis are described in detail. The morphology of the ABR is influenced by both fast and slow mechanisms of adaptation. These results are consistent with previous animal studies based on spike rate. Both fast and slow mechanisms of adaptation are present in all subjects. In addition, the distribution of the jitter and the sequencing of the stimuli may be critical parameters when obtaining reliable ABRs. The separated responses methodology enables for the first time the analysis of the fast and slow mechanisms of adaptation in ABR obtained at stimulation rates greater than 100 Hz. The non-invasive nature of this methodology is appropriate for its use in humans. Copyright © 2013 International Federation of Clinical Neurophysiology. Published by Elsevier Ireland Ltd.

    2009-01-01

    Retinal networks must adapt constantly to best present the ever changing visual world to the brain. Here we test the hypothesis that adaptation is a result of different mechanisms at several synaptic connections within the network. In a companion paper (Part I), we showed that adaptation in the photoreceptors (R1-R6) and large monopolar cells (LMC) of the Drosophila eye improves sensitivity to under-represented signals in seconds by enhancing both the amplitude and frequency distribution of LMCs' voltage responses to repeated naturalistic contrast series. In this paper, we show that such adaptation needs both the light-mediated conductance and feedback-mediated synaptic conductance. A faulty feedforward pathway in histamine receptor mutant flies speeds up the LMC output, mimicking extreme light adaptation. A faulty feedback pathway from L2 LMCs to photoreceptors slows down the LMC output, mimicking dark adaptation. These results underline the importance of network adaptation for efficient coding, and as a mechanism for selectively regulating the size and speed of signals in neurons. We suggest that concert action of many different mechanisms and neural connections are responsible for adaptation to visual stimuli. Further, our results demonstrate the need for detailed circuit reconstructions like that of the Drosophila lamina, to understand how networks process information.

    This paper studies the problem of adaptively adjusted event-triggering mechanism-based fault detection for a class of discrete-time networked control system (NCS) with applications to aircraft dynamics. By taking into account the fault occurrence detection progress and the fault occurrence probability, and introducing an adaptively adjusted event-triggering parameter, a novel event-triggering mechanism is proposed to achieve the efficient utilization of the communication network bandwidth. Both the sensor-to-control station and the control station-to-actuator network-induced delays are taken into account. The event-triggered sensor and the event-triggered control station are utilized simultaneously to establish new network-based closed-loop models for the NCS subject to faults. Based on the established models, the event-triggered simultaneous design of fault detection filter (FDF) and controller is presented. A new algorithm for handling the adaptively adjusted event-triggering parameter is proposed. Performance analysis verifies the effectiveness of the adaptively adjusted event-triggering mechanism, and the simultaneous design of FDF and controller.

    In the transactional model of stress, coping responses are the key to preventing the stress response. In this study, the possible role of psychological well-being as a personal determinant of coping strategies in the academic context was analyzed. Specifically, the study has two objectives: (a) to identify different profiles of students according to their level of psychological well-being; and (b) to analyze the differences between these profiles in the use of three coping strategies (positive reappraisal, support-seeking, and planning). Age, gender, and degree were estimated as covariables. A total of 1,072 university students participated in the study. Latent profile analysis was applied to four indices of psychological well-being: self-acceptance, environmental mastery, purpose in life, and personal growth. An optimal four-profile solution, reflecting significant incremental shifts from low to very high psychological well-being, was obtained. As predicted, the profile membership distinguished between participants in positive reappraisal, support-seeking, and planning. Importantly, the higher the profile of psychological well-being was, the higher the use of the three coping strategies. Gender differences in coping strategies were observed, but no interaction effects with psychological well-being were found. Age and degree were not relevant in explaining the use of coping strategies. These results suggest that psychological well-being stands as an important personal resource to favor adaptive coping strategies for academic stress. PMID:27790168

    Human thermoregulation and acclimatization are core components of the human coping mechanism for withstanding variations in environmental heat exposure. Amidst growing recognition that curtailing global warming to less than two degrees is becoming increasing improbable, human survival will require increasing reliance on these mechanisms. The projected several fold increase in extreme heat events suggests we need to recalibrate health protection policies and ratchet up adaptation efforts. Climate researchers, epidemiologists, and policy makers engaged in climate change adaptation and health protection are not commonly drawn from heat physiology backgrounds. Injecting a scholarly consideration of physiological limitations to human heat tolerance into the adaptation and policy literature allows for a broader understanding of heat health risks to support effective human adaptation and adaptation planning. This paper details the physiological and external environmental factors that determine human thermoregulation and acclimatization. We present a model to illustrate the interrelationship between elements that modulate the physiological process of thermoregulation. Limitations inherent in these processes, and the constraints imposed by differing exposure levels, and thermal comfort seeking on achieving acclimatization, are then described. Combined, these limitations will restrict the likely contribution that acclimatization can play in future human adaptation to global warming. We postulate that behavioral and technological adaptations will need to become the dominant means for human individual and societal adaptations as global warming progresses. PMID:26184272

    Human thermoregulation and acclimatization are core components of the human coping mechanism for withstanding variations in environmental heat exposure. Amidst growing recognition that curtailing global warming to less than two degrees is becoming increasing improbable, human survival will require increasing reliance on these mechanisms. The projected several fold increase in extreme heat events suggests we need to recalibrate health protection policies and ratchet up adaptation efforts. Climate researchers, epidemiologists, and policy makers engaged in climate change adaptation and health protection are not commonly drawn from heat physiology backgrounds. Injecting a scholarly consideration of physiological limitations to human heat tolerance into the adaptation and policy literature allows for a broader understanding of heat health risks to support effective human adaptation and adaptation planning. This paper details the physiological and external environmental factors that determine human thermoregulation and acclimatization. We present a model to illustrate the interrelationship between elements that modulate the physiological process of thermoregulation. Limitations inherent in these processes, and the constraints imposed by differing exposure levels, and thermal comfort seeking on achieving acclimatization, are then described. Combined, these limitations will restrict the likely contribution that acclimatization can play in future human adaptation to global warming. We postulate that behavioral and technological adaptations will need to become the dominant means for human individual and societal adaptations as global warming progresses.

    This study is a follow-up to a study previously published in this journal that reported the moderating function of exercise exertion amid the relationship between age and low back pain (LBP) among consistent exercise participants. The current study analyzed factors of psychological adaptation as potential mediators within the age--LBP relationship. Measures of psychological adaptation included psychological vulnerability, avoidant coping, resilient coping, and perceived resilience. The sample reported slightly moderate psychological vulnerability; a moderate extent of avoidant coping and resilient coping; and high resilience. Age inversely correlated with psychological vulnerability and avoidance coping. LBP correlated inversely with avoidant coping. Avoidant coping positively mediated (enhanced) age's effect on LBP. Results from this follow-up analysis highlight the importance of understanding and testing psychological factors in models with age and a physical health outcome.

    Dialysis patients need to deal and cope with various aspects of their disease. Identifying the adaptation methods provides valuable information for planning specific treatment and medical care delivery and improving the performance of medical teams. The present study aims to evaluate the coping strategies to stress among patients undergoing hemodialysis (HD) and peritoneal dialysis (PD) at the Imam Reza Educational-Medical Hospital, Tabriz, West Azarbaijan, Iran. This descriptive and analytical study was conducted on 70 patients in the year 2012. The subjects were selected through census method and simple random sampling method. Data were collected using a customized questionnaire and consisted of demographic information and the Jalowiec Coping Scale (JCS) through a structured interview. Descriptive and inferential statistics were used to analyze the data in SPSS (version 13). The mean score of frequency of use of the coping strategy as "sometimes used" for the HD patients was 70.94 ± 18.91 and also for PD patients as "seldom used" was 58.70 ± 12.66. The mean score of helpfulness of coping strategies in the HD group was 49.57 ± 19.42 as "slightly helpful", whereas in the PD group it was 37.21 ± 14.38 as "slightly helpful" Furthermore, both groups used the emotion-oriented coping styles more frequently than the problem-oriented methods. HD patients used coping methods more frequently than the PD patients. The majority of patients used emotion-oriented coping strategies to deal with stress factors. Use of educational, counseling and supportive programs to assist in coping techniques can facilitate the coping process with stress factors in dialysis patients.

    The current article offers suggestions for ways to adapt empirically supported treatments (ESTs). A specific manualized EST (Coping Cat; Kendall & Hedtke, 2006a) is used to illustrate the concept of “flexibility within fidelity” (Kendall & Beidas, 2007; Kendall, Gosch, Furr, & Sood, 2008). Flexibility within fidelity stresses the importance of using ESTs while considering and taking into account individual client presentations. In this discussion, recommendations are offered for the use of the Coping Cat with younger youth, adolescents, and youth with secondary comorbidities (i.e., social skills deficits, inattentive symptoms, and depressive symptoms).

    Addiction rates in nurses are higher than in the general population. The relationship between stress, coping, and adaptation in nurses (N = 82) enrolled in a recovery and monitoring program in the state of New Jersey was examined. Social support, a variable tested as a mediator of this relationship, was also examined. Participants completed the Perceived Stress Scale, Multidimensional Scale of Perceived Social Support, and Psychological General Well-Being Index. Negative relationships were found between stress and social support and stress and well-being, and a positive relationship was found between social support and well-being (all ps < .05). The direct relationship between stress and well-being was decreased in the presence of social support. The findings of this research suggest that, to assist nurses, an increased awareness of stress and its injurious effects on overall well-being must be identified so proactive measures can be implemented to prevent potential untoward consequences. Ultimately, methods to strengthen social support and social networks will enhance the probability of sustained recovery, relapse prevention, and safe reentry into nursing practice. Implications for behavioral health providers and health care practitioners are discussed.

    A study was carried out to discover trends in the rainfall and temperature pattern of the Alaknanda catchment in the Central Himalaya. Data on the annual rainfall, monsoon rainfall for the last decade, and average annual temperatures over the last few decades were analyzed. Nonparametric methods (Mann-Kendall and Sen's method) were employed to identify trends. The Mann-Kendall test shows a decline in rainfall and rise in temperature, and these trends were found to be statistically significant at the 95% confidence level for both transects. Sen's method also confirms this trend. This aspect has to be considered seriously for the simple reason that if the same trend continues in the future, more chances of drought are expected. The impact of climate change has been well perceived by the people of the catchment, and a coping mechanism has been developed at the local level.

    Coping, the psychological adaptation to stressors and serious life events, has been found to have a great influence on the development and persistence of posttraumatic complaints. Coping has received much attention for having been found to be modifiable in treatment following mild traumatic brain injury (mTBI) and for its potential to identify the Patients who are at risk of suffering from long-term complaints. Currently, coping styles are assumed to be stable over time. Although interventions to facilitate adaptive coping are given at different time intervals after the injury, little is known about spontaneous changes in preferred strategies over time following mTBI. This study aimed to investigate the stability of different coping styles over a one-year period following mTBI (at two weeks', six and twelve months' post-injury) and to investigate the relation between coping styles and feelings of self-efficacy. We included 425 mTBI patients (Glasgow Coma Scale [GCS] score 13-15) admitted to three Level-1 trauma centers in the Netherlands as part of a prospective follow-up study. All participants filled out The Utrecht Coping List (UCL) to determine their position on seven coping subscales. Most coping styles showed a decrease over time, except for positive reframing, which showed a decrease and then increased. Interestingly, the passive coping style was found to stabilize over time within the year after injury. High feelings of self-efficacy were related to a high active coping style (r = 0.36), and low feelings of self-efficacy with passive coping (r = -0.32). These results hold important possibilities for the use of the passive coping strategy as an inclusion criterion for intervention studies and an entry point for treatment itself. Considering the intertwinement of coping with self-efficacy, improving feelings of self-efficacy could form an effective part of an intervention to improve outcome. Copyright © 2017 Elsevier Ltd.

  19. Transfer of adaptation reveals shared mechanism in grasping and manual estimation.

    PubMed

    2018-06-19

    An influential idea in cognitive neuroscience is that perception and action are highly separable brain functions, implemented in distinct neural systems. In particular, this theory predicts that the functional distinction between grasping, a skilled action, and manual estimation, a type of perceptual report, should be mirrored by a split between their respective control systems. This idea has received support from a variety of dissociations, yet many of these findings have been criticized for failing to pinpoint the source of the dissociation. In this study, we devised a novel approach to this question, first targeting specific grasp control mechanisms through visuomotor adaptation, then testing whether adapted mechanisms were also involved in manual estimation - a response widely characterized as perceptual in function. Participants grasped objects in virtual reality that could appear larger or smaller than the actual physical sizes felt at the end of each grasp. After brief exposure to a size perturbation, manual estimates were biased in the same direction as the maximum grip apertures of grasping movements, indicating that the adapted mechanism is active in both tasks, regardless of the perception-action distinction. Additional experiments showed that the transfer effect generalizes broadly over space (Exp. 1B) and does not appear to arise from a change in visual perception (Exp. 2). We discuss two adaptable mechanisms that could have mediated the observed effect: (a) an afferent proprioceptive mechanism for sensing grip shape; and (b) an efferent visuomotor transformation of size information into a grip-shaping motor command.

    Relationships between bully victimization and symptoms of depression/anxiety were examined. In addition, it was studied whether this relationship was moderated by specific cognitive coping strategies. Participants were 582 secondary school students who filled out online self-report questionnaires on bully victimization, cognitive coping, and depression/anxiety. (Moderated) Multiple Regression analysis was performed. Strong relationships were found between bully victimization and symptoms of depression and anxiety. On top of that, two cognitive coping strategies moderated the relationship between bullying and depression, i.e. rumination (strengthening) and positive refocusing (reducing). Cognitive coping strategies that moderated the effect of bullying on anxiety symptoms were rumination, catastrophizing (strengthening) and positive reappraisal (reducing). The results provide possible targets for intervention: when helping adolescents who have been bullied, maladaptive cognitive coping strategies could be assessed and challenged, while more adaptive strategies could be acquired.

    Antipsychotics are often the first line of treatment for individuals with schizophrenia (Fialko et al., 2008). One challenge to effective treatment is lack of adherence to prescribed medication. Lower rates of adherence are associated with considerably higher rates of relapse and poorer course of illness. Therefore studying characteristics that may be related to medication adherence is important. Coping styles may be one such factor. Individuals utilize a variety of coping mechanisms to manage and navigate difficult life events, including mental illness (Cooke et al., 2007). In the present study, forty individuals with schizophrenia were assessed regarding their coping styles and medication adherence practices. As hypothesized, it was found that denial coping was inversely related to medication adherence. However, contrary to expectations, acceptance coping was not related to medication adherence. These findings suggest that targeting denial coping strategies in treatment may help foster more optimal strategies for managing schizophrenia. PMID:19684494

    Individual coping strategies and dyadic coping independently predict partner well-being and relationship functioning; however, it is unclear whether the coping processes are inter-related and whether they uniquely contribute to romantic relationship functioning. One hundred heterosexual dating couples rated the individual coping strategy of negative mood regulation as well as positive and negative dyadic coping. Relationship functioning was assessed via partners’ reports of relationship satisfaction and observers’ ratings of negative interaction in conflict. Actor-Partner Interdependence Models (APIMs; Cook & Kenny, 2005; Kashy & Kenny, 2000) revealed associations between individual coping and dyadic coping in the predicted directions. APIMs also indicated the unique contributions of positive and negative dyadic coping to relationship functioning, above and beyond contributions of individual coping strategies. Implications of dyadic coping as a target of efforts to prevent or treat partner and/or relational distress are discussed. PMID:20954765

    2014-01-01

    There has been a growing interest amongst researchers and practitioners regarding the various coping strategies adopted by women experiencing intimate partner abuse (IPA). These studies have tended to adopt and adapt the stress-coping model developed by Lazarus and Folkman (1984) and thus make the distinction between emotion and problem-solving coping strategies and the resources available for women to cope. Even though, contemporary coping scholars acknowledge the role of employment and coping, it is still unclear as to how employment facilitates women's coping strategies. Drawing on findings from a qualitative study, this article explores how employment and workplace environments provide survivors of IPA with resources that allow them to cope with the abuse. By incorporating theoretical insights developed in the field of organizational studies, namely boundary work and organizational identities, these findings develop our understanding of the role of employment in survivors' coping strategies. Finally, the findings demonstrate the valuable contribution of interdisciplinarity in furthering our knowledge of coping strategies and the positive aspects of employment for survivors of IPA.

    How certain aspects of human learning can be used to characterize learning in intelligent adaptive control systems is investigated. Reflexive and declarative memory and learning are described. It is shown that model-based systems-theoretic adaptive control methods exhibit attributes of reflexive learning, whereas the problem-solving capabilities of knowledge-based systems of artificial intelligence are naturally suited for implementing declarative learning. Issues related to learning in knowledge-based control systems are addressed, with particular attention given to rule-based systems. A mechanism for real-time rule-based knowledge acquisition is suggested, and utilization of this mechanism within the context of failure diagnosis for fault-tolerant flight control is demonstrated.

    In BIID a disorder of body identity, concerned subjects desire an amputation of a healthy limb. So far, no psychiatric comorbidity was found in the few studies on BIID-subjects. This study explored clinical symptoms, personality characteristics, interpersonal aspects and coping strategies in 15 BIID persons. Psychometric testing on the topics (1) clinical symptoms, (2) personality and interpersonal aspects, (3) coping strategies, (4) attitudes towards the body were used and statistically evaluated with the T-test for one sample. Some psychopathologies such as depression, anxiety and obsessive-compulsive disorders (OCD) could be excluded although an increased tendency of depressiveness was found. BIID subjects showed specific personality and interpersonal characteristics: high agreeableness, autonomy, autarky and restrained behaviour towards others. Stress and conflicts are managed by self-control and self-affirmation. Their subjective physical attractiveness was low. BIID persons do not exhibit psychopathological characteristics (such as anxiety, depression or OCD), but do show specifics in personality, relationships and coping mechanisms. In the future, further personality traits and personality disorders should be investigated to shed more light on the categorisation and treatment of BIID. © Georg Thieme Verlag KG Stuttgart · New York.

    Quality of life in parents of children suffering from haemophilia may be diminished by the illness burden experienced in daily life and by non-adaptive ways of coping. The aim of this study was to examine the relation between parents' quality of life, their perceived psychosocial strains and ways of coping, and to compare parents' outcome to other paediatric illness groups (juvenile idiopathic arthritis, type 1 diabetes). In a cross-sectional study, parents completed a questionnaire concerning quality of life, psychosocial strains, coping strategies and needs as well as sociodemographic and illness parameters. Study participants were recruited in an ambulant haemophilia centre. A total of 55 parents (32 mothers, 23 fathers; age = 39.6; SD = 8.6) of children suffering from haemophilia (age = 11.0; SD = 6.4) took part in the study. Comparison groups were parents of children with juvenile idiopathic arthritis (n = 161) and parents of children with type 1 diabetes (n = 69). Compared to parents from other paediatric illness groups, the parents of children with haemophilia experience less impact on their quality of life and lower psychosocial strains. Quality of life was predicted by the coping strategy 'improving marital relationship' (beta = 0.48) and by emotional strains and worries concerning future (beta = -0.43; explained variance 49%). Parents reported a pronounced need for further information on the comprehensive management of haemophilia. In the psychosocial care of families with a child suffering from -haemophilia, reducing psychosocial strains and strengthening adaptive coping strategies may be a preventive intervention for improving parents' quality of life.

  8. Oxidative stress adaptation with acute, chronic, and repeated stress.

    Pickering, Andrew M; Vojtovich, Lesya; Tower, John; A Davies, Kelvin J

    2013-02-01

    Oxidative stress adaptation, or hormesis, is an important mechanism by which cells and organisms respond to, and cope with, environmental and physiological shifts in the level of oxidative stress. Most studies of oxidative stress adaption have been limited to adaptation induced by acute stress. In contrast, many if not most environmental and physiological stresses are either repeated or chronic. In this study we find that both cultured mammalian cells and the fruit fly Drosophila melanogaster are capable of adapting to chronic or repeated stress by upregulating protective systems, such as their proteasomal proteolytic capacity to remove oxidized proteins. Repeated stress adaptation resulted in significant extension of adaptive responses. Repeated stresses must occur at sufficiently long intervals, however (12-h or more for MEF cells and 7 days or more for flies), for adaptation to be successful, and the levels of both repeated and chronic stress must be lower than is optimal for adaptation to acute stress. Regrettably, regimens of adaptation to both repeated and chronic stress that were successful for short-term survival in Drosophila nevertheless also caused significant reductions in life span for the flies. Thus, although both repeated and chronic stress can be tolerated, they may result in a shorter life. Copyright © 2012 Elsevier Inc. All rights reserved.

    Data on long-term consequences of preterm birth on pain coping later in life are limited. To assess whether gestational age, birth weight and neonatal disease severity have effect on pain coping style in adolescents born preterm or with low birth weight. Observational, longitudinal study (Project On Preterm and SGA-infants, POPS-19). We analyzed data of 537 adolescents at the age of 19 years, who were born at a gestational age <32 weeks or with a birth weight <1500g. Participants completed the pain coping questionnaire (PCQ) that assesses pain coping strategies in three higher-order factors: approach ("to deal with pain"), problem-focused avoidance ("to disengage from pain") and emotion-focused avoidance ("expression of pain"). Furthermore, their pain coping effectiveness, pain controllability and emotional reactions to pain were assessed. All participants completed an IQ test. Univariate analysis showed no significant correlation between length of stay, sepsis and necrotizing enterocolitis and any of the higher-order factors. Approach was only correlated with IQ. Problem-focused avoidance was, in the multiple regression analysis (including gestational age, IVH and IQ), only correlated with IQ. For emotion-focused avoidance (including birth weight, SGA, IVH, respiratory support and IQ) three independent predictors remained: IVH was positively correlated, while respiratory support and IQ were negatively correlated with emotion-focused avoidance. Early neonatal characteristics and neonatal disease severity have limited effect on pain coping style in adolescence. Higher IQ was associated with the use of adaptive coping strategies, while maladaptive strategies were used less. Copyright © 2016. Published by Elsevier Ireland Ltd.

    2014-07-01

    This article explores how children use fantasy, play, and coping (imaginal coping) in order to handle chronic illness. Imaginal coping, as a theoretical construct, is defined as the use of imagination to deal with the hardships of illness. The overarching aim has been to investigate the various ways in which categories of staff members (doctors, nurses, play therapists, and hospital clowns) and parents support children in their coping. Focus has thus been on collaborative or interactive aspects of playful coping. A large proportion of the data collected consists of 93 h of video-recorded interactions between children, parents and staff. The collection of data involved fieldwork carried out with the use of a video ethnographic method, making it possible thereby to analyse and work with data in greater detail. For more than one year, five children with leukaemia were followed as each made their regular visits to a children's cancer clinic in a children's hospital in Sweden. Collaborative storytelling, humorous treatment practices, playful rituals, as well as role-reversal play, were all types of events involving staff-child collaboration and creative improvisation. Staff, along with parents, played a significant role in the coping process. In various ways, the staff members helped the parents to respond to their children in ways adaptive for coping. It can be seen that imaginal coping is a highly interactional business. In this study it is shown that parents socialize coping; this is sometimes undertaken explicitly, for example, through coaching (in the form of instructions or suggestions) and teaching. But often it is achieved through modelling or intent participation, with the child observing staff members' treatment practices. © 2013 John Wiley & Sons Ltd.

    Anterior piriform cortex (aPCX) neurons rapidly filter repetitive odor stimuli despite relatively maintained input from mitral cells. This cortical adaptation is correlated with short-term depression of afferent synapses, in vivo. The purpose of this study was to elucidate mechanisms underlying this nonassociative neural plasticity using in vivo and in vitro preparations and to determine its role in cortical odor adaptation. Lateral olfactory tract (LOT)-evoked responses were recorded in rat aPCX coronal slices. Extracellular and intracellular potentials were recorded before and after simulated odor stimulation of the LOT. Results were compared with in vivo intracellular recordings from aPCX layer II/III neurons and field recordings in urethane-anesthetized rats stimulated with odorants. The onset, time course, and extent of LOT synaptic depression during both in vitro electrical and in vivo odorant stimulation methods were similar. Similar to the odor specificity of cortical odor adaptation in vivo, there was no evidence of heterosynaptic depression between independent inputs in vitro. In vitro evidence suggests at least two mechanisms contribute to this activity-dependent synaptic depression: a rapidly recovering presynaptic depression during the initial 10-20 sec of the post-train recovery period and a longer lasting (approximately 120 sec) depression that can be blocked by the metabotropic glutamate receptor (mGluR) II/III antagonist (RS)-alpha-cyclopropyl-4-phosphonophenylglycine (CPPG) and by the beta-adrenergic receptor agonist isoproterenol. Importantly, in line with the in vitro findings, both adaptation of odor responses in the beta (15-35 Hz) spectral range and the associated synaptic depression can also be blocked by intracortical infusion of CPPG in vivo.

    2009-09-02

    Organisms have the property to adapt to a changing environment and keep certain components within a cell regulated at the same level (homeostasis). "Perfect adaptation" describes an organism's response to an external stepwise perturbation by regulating some of its variables/components precisely to their original preperturbation values. Numerous examples of perfect adaptation/homeostasis have been found, as for example, in bacterial chemotaxis, photoreceptor responses, MAP kinase activities, or in metal-ion homeostasis. Two concepts have evolved to explain how perfect adaptation may be understood: In one approach (robust perfect adaptation), the adaptation is a network property, which is mostly, but not entirely, independent of rate constant values; in the other approach (nonrobust perfect adaptation), a fine-tuning of rate constant values is needed. Here we identify two classes of robust molecular homeostatic mechanisms, which compensate for environmental variations in a controlled variable's inflow or outflow fluxes, and allow for the presence of robust temperature compensation. These two classes of homeostatic mechanisms arise due to the fact that concentrations must have positive values. We show that the concept of integral control (or integral feedback), which leads to robust homeostasis, is associated with a control species that has to work under zero-order flux conditions and does not necessarily require the presence of a physico-chemical feedback structure. There are interesting links between the two identified classes of homeostatic mechanisms and molecular mechanisms found in mammalian iron and calcium homeostasis, indicating that homeostatic mechanisms may underlie similar molecular control structures.

  16. Evolution of time-keeping mechanisms: early emergence and adaptation to photoperiod

    PubMed Central

    Hut, R. A.; Beersma, D. G. M.

    2011-01-01

    Virtually all species have developed cellular oscillations and mechanisms that synchronize these cellular oscillations to environmental cycles. Such environmental cycles in biotic (e.g. food availability and predation risk) or abiotic (e.g. temperature and light) factors may occur on a daily, annual or tidal time scale. Internal timing mechanisms may facilitate behavioural or physiological adaptation to such changes in environmental conditions. These timing mechanisms commonly involve an internal molecular oscillator (a ‘clock’) that is synchronized (‘entrained’) to the environmental cycle by receptor mechanisms responding to relevant environmental signals (‘Zeitgeber’, i.e. German for time-giver). To understand the evolution of such timing mechanisms, we have to understand the mechanisms leading to selective advantage. Although major advances have been made in our understanding of the physiological and molecular mechanisms driving internal cycles (proximate questions), studies identifying mechanisms of natural selection on clock systems (ultimate questions) are rather limited. Here, we discuss the selective advantage of a circadian system and how its adaptation to day length variation may have a functional role in optimizing seasonal timing. We discuss various cases where selective advantages of circadian timing mechanisms have been shown and cases where temporarily loss of circadian timing may cause selective advantage. We suggest an explanation for why a circadian timing system has emerged in primitive life forms like cyanobacteria and we evaluate a possible molecular mechanism that enabled these bacteria to adapt to seasonal variation in day length. We further discuss how the role of the circadian system in photoperiodic time measurement may explain differential selection pressures on circadian period when species are exposed to changing climatic conditions (e.g. global warming) or when they expand their geographical range to different latitudes or

    It has been shown that mechanical stretches imposed on airway smooth muscle (ASM) by deep inspiration reduce the subsequent contractile response of the ASM. This passive maneuver of lengthening and retraction of the muscle is beneficial in normal subjects to counteract bronchospasm. However, it is detrimental to hyperresponsive airways because it triggers further bronchoconstriction. Although the exact mechanisms for this contrary response by normal and hyperresponsive airways are unclear, it has been suggested that the phenomenon is related to changes in ASM adaptability to mechanical oscillation. Healthy immature airways of both human and animal exhibit hyperresponsiveness, but whether the adaptative properties of hyperresponsive airway differ from normal is still unknown. In this article, we review the phenomenon of ASM adaptation to mechanical oscillation and its relevance and implication to airway hyperresponsiveness. We demonstrate that the age-specific expression of ASM adaptation is prominent using an established maturational animal model developed in our laboratory. Our data on immature ASM showed potentiated contractile force shortly after a length oscillation compared with the maximum force generated before oscillation. Several potential mechanisms such as myogenic response, changes in actin polymerization, or changes in the quantity of the cytoskeletal regulatory proteins plectin and vimentin, which may underlie this age-specific force potentiation, are discussed. We suggest a working model of the structure of smooth muscle associated with force transmission, which may help to elucidate the mechanisms responsible for the age-specific expression of smooth muscle adaptation. It is important to study the maturational profile of ASM adaptation as it could contribute to juvenile hyperresponsiveness.

    Parents rearing children with developmental disabilities encounter stressors that require coping and adaptation. In Glidden et al. 2006, the use of problem-focused coping strategies was more often associated with positive adjustment outcomes than was the use of emotion-focused coping strategies, and parental personality was shown to influence outcomes, with Neuroticism, in particular, associated with lower well-being. In the current study we aimed to replicate these results for adjustment outcomes measured 6 years later. Sixty-eight married couples parenting at least one child with developmental disabilities completed measures of depression and subjective well-being, and the Transition Daily Rewards and Worries Questionnaire, an inventory that assesses parental reaction to children transitioning into adulthood. For both mothers and fathers, combinations of personality factors and coping strategies were able to significantly predict outcome variables measured 6 years later. Personality, however, was a better predictor for mothers, whereas coping strategies predicted more variance for fathers. Distancing, especially, demonstrated mother-father differences. For the most part, the current results demonstrated that the relations among personality, coping and parental outcomes were consistent and stable over the 6-year interval. In addition, although we found some differences between mothers and fathers, there were also many similarities in the frequency of use of different coping strategies, and in the direction of influence of personality and coping strategy on outcome variables.

    Active coping underlies a healthy stress response, but neural processes supporting such resilient coping are not well-known. Using a brief, sustained exposure paradigm contrasting highly stressful, threatening, and violent stimuli versus nonaversive neutral visual stimuli in a functional magnetic resonance imaging (fMRI) study, we show significant subjective, physiologic, and endocrine increases and temporally related dynamically distinct patterns of neural activation in brain circuits underlying the stress response. First, stress-specific sustained increases in the amygdala, striatum, hypothalamus, midbrain, right insula, and right dorsolateral prefrontal cortex (DLPFC) regions supported the stress processing and reactivity circuit. Second, dynamic neural activation during stress versus neutral runs, showing early increases followed by later reduced activation in the ventrolateral prefrontal cortex (VLPFC), dorsal anterior cingulate cortex (dACC), left DLPFC, hippocampus, and left insula, suggested a stress adaptation response network. Finally, dynamic stress-specific mobilization of the ventromedial prefrontal cortex (VmPFC), marked by initial hypoactivity followed by increased VmPFC activation, pointed to the VmPFC as a key locus of the emotional and behavioral control network. Consistent with this finding, greater neural flexibility signals in the VmPFC during stress correlated with active coping ratings whereas lower dynamic activity in the VmPFC also predicted a higher level of maladaptive coping behaviors in real life, including binge alcohol intake, emotional eating, and frequency of arguments and fights. These findings demonstrate acute functional neuroplasticity during stress, with distinct and separable brain networks that underlie critical components of the stress response, and a specific role for VmPFC neuroflexibility in stress-resilient coping.

    This study examined (a) the role of avoidance coping in prospectively generating both chronic and acute life stressors and (b) the stress-generating role of avoidance coping as a prospective link to future depressive symptoms. Participants were 1,211 late-middle-aged individuals (500 women and 711 men) assessed 3 times over a 10-year period. As predicted, baseline avoidance coping was prospectively associated with both more chronic and more acute life stressors 4 years later. Furthermore, as predicted, these intervening life stressors linked baseline avoidance coping and depressive symptoms 10 years later, controlling for the influence of initial depressive symptoms. These findings broaden knowledge about the stress-generation process and elucidate a key mechanism through which avoidance coping is linked to depressive symptoms. PMID:16173853

    Aging effects, environmental changes, thermal drifts, and soft and hard faults affect physical systems by changing their nature and behavior over time. To cope with a process evolution adaptive solutions must be envisaged to track its dynamics; in this direction, adaptive classifiers are generally designed by assuming the stationary hypothesis for the process generating the data with very few results addressing nonstationary environments. This paper proposes a methodology based on k-nearest neighbor (NN) classifiers for designing adaptive classification systems able to react to changing conditions just-in-time (JIT), i.e., exactly when it is needed. k-NN classifiers have been selected for their computational-free training phase, the possibility to easily estimate the model complexity k and keep under control the computational complexity of the classifier through suitable data reduction mechanisms. A JIT classifier requires a temporal detection of a (possible) process deviation (aspect tackled in a companion paper) followed by an adaptive management of the knowledge base (KB) of the classifier to cope with the process change. The novelty of the proposed approach resides in the general framework supporting the real-time update of the KB of the classification system in response to novel information coming from the process both in stationary conditions (accuracy improvement) and in nonstationary ones (process tracking) and in providing a suitable estimate of k. It is shown that the classification system grants consistency once the change targets the process generating the data in a new stationary state, as it is the case in many real applications.

    A dyslexia coping programme entitled Success and Dyslexia was implemented in two primary schools within a whole-class coping programme and whole-school dyslexia professional development context. One hundred and two year 6 students, 23 of whom had dyslexia, undertook surveys pretest, post-test and at 1-year follow-up. Effectiveness of the coping programme and maintenance of effects for the students after transition to secondary school were investigated. Inclusion of contrast group data in the follow-up year suggested significant positive changes at first and second follow-ups in locus of control and nonproductive coping may also be associated with increase in age. Most trends were in the expected direction, especially for students with dyslexia. At follow-up, students with dyslexia reported similar perceived control and adaptive coping to students without dyslexia rather than a decrease in these areas as is usually the case. A larger sample and an ongoing control group are needed to confirm these results. Copyright © 2013 John Wiley & Sons, Ltd.

    Clinical training has been recognized as a stressful experience for nursing students. The aims of this study were to identify levels and types of stressors among nursing students during their clinical training and their coping behaviors. Data were collected using a purposive sampling method from 100 nursing students using a self-reported questionnaire composed of Perceived Stress Scale and Coping Behavior Inventory. Results showed that "assignments and workload" as well as "teachers and nursing staff" were the highest sources of stress in clinical training. The most common coping behaviors used were "problem-solving" and "staying optimistic". There was a significant difference in perceived stress among students in regard to the way of choosing nursing. There were significant differences in coping behaviors in regard to the presence of relatives in nursing, living status and mothers' educational level. The predictors of perceived stress were self-choosing for nursing and the presence of relatives in nursing, while the predictors for coping behaviors were stress from peers and daily life as well as mothers' educational level. Nursing teachers and staff are encouraged to develop strategies that decrease level of stress and promote adaptive coping behaviors among nursing students during their clinical training.

    Aggression is a characteristic feature of many psychiatric disorders. To address the scarceness for evidence-based interventions for behavioral problems in Pakistan, we evaluated the effectiveness of culturally adapted version of Coping Power Program. The purpose of the study was to determine the extent to which Coping Power Program is capable of reducing aggressive behavior and improving competent behavior, when delivered in a different culture, i.e., Pakistan. With randomized control trial (RCT) of pre- and post-testing, 112 fourth grade boys were allocated to Coping Power intervention condition and waitlist control condition. The intervention group showed significant reduction in aggression at post assessment, in comparison to control group. Boys who received Coping Power intervention also showed improvements in behavior, social skills, and social cognitive processes, with better anger control and problem solving strategies, in comparison to the control group. The results of the study provide preliminary evidence, supporting the effectiveness of Coping Power Program for Pakistani children. Despite its limitations, the results of this study are promising and suggest that Coping Power is an effective intervention to reduce behavioral problems and promote healthy and positive behaviors in children, even when implemented in different contexts with greater potential for violence exposure.

    Oral health is essential to general health and well-being and is severely impacted by head and neck cancer (HNC) and its treatment. This study aimed to describe how people who have been treated for HNC cope with altered oral health and function and to identify their supportive care needs. A qualitative, descriptive approach was used. Data was collected from individual interviews with six participants 6 months after treatment. Data analysis was performed by qualitative content analysis involving inductive and directed approaches. Directed content analysis was guided by the Stress, Appraisal and Coping Model. Three themes describing changed oral health were identified from the data: dimensions of eating, maintaining oral health after treatment and adapting to the chronic side effects of treatment. A strong use of problem-focussed coping was described, in addition to the importance of peer support in adapting to the psychosocial outcomes of treatment. Support needs identified related to increased access to specialist dental oncology services post treatment, information needs and a need for more psychological support. The study findings describe the experience of a sample of people who have received treatment for HNC. Due to a demographically homogenous sample and the strong use of positive coping strategies, the results presented may not describe the experience of the wider HNC population; however, these results provide insight into factors that may influence positive coping.

    Thermal perception is a fundamental physiological process pertaining to the vast majority of organisms. In vertebrates, environmental temperature is detected by the primary afferents of the somatosensory neurons in the skin, which express a ‘choir’ of ion channels tuned to detect particular temperatures. Nearly two decades of research have revealed a number of receptor ion channels that mediate the perception of several temperature ranges, but most still remain molecularly orphaned. Yet even within this well-researched realm, most of our knowledge largely pertains to two closely related species of rodents, mice and rats. While these are standard biomedical research models, mice and rats provide a limited perspective to elucidate the general principles that drive somatosensory evolution. In recent years, significant advances have been made in understanding the molecular mechanism of temperature adaptation in evolutionarily distant vertebrates and in organisms with acute thermal sensitivity. These studies have revealed the remarkable versatility of the somatosensory system and highlighted adaptations at the molecular level, which often include changes in biophysical properties of ion channels from the transient receptor potential family. Exploiting non-standard animal models has the potential to provide unexpected insights into general principles of thermosensation and thermoregulation, unachievable using the rodent model alone.

    The present study was prompted by the lack of agreement on how coping changes with age. We postulate that the effect of age on coping is mediated by coping resources, such as self-efficacy, perceived stress and social support satisfaction. The participants in the study were community dwelling and aged between 22 and 88 years old. Data were collected using the General Self Efficacy Scale, the Social Support Questionnaire, the Perceived Stress Scale, the Geriatric Depression Scale, the Social Readjustment Rating Scale (life-events) and the Way of Coping Checklist. We performed path analyses for two competitive structural models: M1 (age does not directly affect coping processes) and M2 (age directly affects coping processes). Our results supported a modified version of M2. Age was not found to predict either of two coping strategies: problem-focused coping is predicted by self-efficacy and social support satisfaction; emotion-focused coping is predicted by social support satisfaction and perceived stress. Changes in coping over the lifespan reflect the effectiveness with which a person's adaptive processes deal with age-associated changes in self-referred beliefs and environment perception.

    The robust control synthesis of continuous-time nonlinear systems with uncertain term is investigated via event-triggering mechanism and adaptive critic learning technique. We mainly focus on combining the event-triggering mechanism with adaptive critic designs, so as to solve the nonlinear robust control problem. This can not only make better use of computation and communication resources, but also conduct controller design from the view of intelligent optimization. Through theoretical analysis, the nonlinear robust stabilization can be achieved by obtaining an event-triggered optimal control law of the nominal system with a newly defined cost function and a certain triggering condition. The adaptive critic technique is employed to facilitate the event-triggered control design, where a neural network is introduced as an approximator of the learning phase. The performance of the event-triggered robust control scheme is validated via simulation studies and comparisons. The present method extends the application domain of both event-triggered control and adaptive critic control to nonlinear systems possessing dynamical uncertainties. Copyright © 2018 Elsevier Ltd.

    Coping planning, the formation of plans to overcome behavioral barriers is assumed to promote health behavior maintenance, but the literature on this is inconsistent. In this study, we aimed to investigate the mechanisms of a coping planning intervention that adversely affected maintained safe water consumption. We also explored perceived behavioral difficulty as a potential moderator of coping planning interventions. In the second phase of a cluster-randomised trial, households (N = 177 analyzed) were randomly allocated to a coping planning intervention or a comparison group (repetition of interventions from first intervention phase). Safe water consumption, the mechanisms of coping planning, and perceived difficulty were measured pre-post. The data were analyzed using mediation and moderated mediation analysis. Changes in behavioral intention mediated the intervention effects on behavioral maintenance (b = -0.36, 95% CI [-0.91, -0.03]). Changes in perceived coping planning (b = 0.08, 95% CI [-0.12, 0.34]), and maintenance self-efficacy (b = -0.13, 95% CI [-0.45, 0.01]) did not mediate the effects. Prior perceived difficulty moderated the coping planning intervention effects on maintenance via intention. Coping planning may decrease motivation for health behavior maintenance for persons who experienced few barriers prior to the planning intervention. © 2018 The International Association of Applied Psychology.

    Despite efforts to eliminate it at the societal level, HIV stigma persists and continues to threaten the health of people living with HIV (PLWH). We tested whether social support, adaptive coping, and/or HIV identity centrality act as resilience resources by buffering people from the negative impact of enacted and/or anticipated stigma on stress and ultimately HIV symptoms. Ninety-three PLWH completed a survey, and data analyses tested for evidence of mediation and moderation. Results demonstrated that instrumental social support, perceived community support, and HIV identity centrality buffered participants from the association between anticipated stigma and HIV symptoms. That is, anticipated stigma was associated with HIV symptoms via stress only at low levels of these resources. No resources buffered participants from the impact of enacted stigma. Identifying and enhancing resilience resources among PLWH is critical for protecting PLWH from the harmful effects of stigma. PMID:24715226

  11. On the maintenance of genetic variation and adaptation to environmental change: considerations from population genomics in fishes.

    2016-12-01

    The first goal of this paper was to overview modern approaches to local adaptation, with a focus on the use of population genomics data to detect signals of natural selection in fishes. Several mechanisms are discussed that may enhance the maintenance of genetic variation and evolutionary potential, which have been overlooked and should be considered in future theoretical development and predictive models: the prevalence of soft sweeps, polygenic basis of adaptation, balancing selection and transient polymorphisms, parallel evolution, as well as epigenetic variation. Research on fish population genomics has provided ample evidence for local adaptation at the genome level. Pervasive adaptive evolution, however, seems to almost never involve the fixation of beneficial alleles. Instead, adaptation apparently proceeds most commonly by soft sweeps entailing shifts in frequencies of alleles being shared between differentially adapted populations. One obvious factor contributing to the maintenance of standing genetic variation in the face of selective pressures is that adaptive phenotypic traits are most often highly polygenic, and consequently the response to selection should derive mostly from allelic co-variances among causative loci rather than pronounced allele frequency changes. Balancing selection in its various forms may also play an important role in maintaining adaptive genetic variation and the evolutionary potential of species to cope with environmental change. A large body of literature on fishes also shows that repeated evolution of adaptive phenotypes is a ubiquitous evolutionary phenomenon that seems to occur most often via different genetic solutions, further adding to the potential options of species to cope with a changing environment. Moreover, a paradox is emerging from recent fish studies whereby populations of highly reduced effective population sizes and impoverished genetic diversity can apparently retain their adaptive potential in some

    This study examined whether coping moderated the impact of community violence exposure (CVE) on violent behavior among 285 urban African American and Latino adolescent males assessed annually across five years. Composites indicating overall CVE (having knowledge of others’ victimization, witnessing violence, direct victimization) and approach to coping with CVE were created by averaging across years 1–3 (Time 1; mean ages 14–16). Adolescents classified as coping effectively tended to respond to CVE in beneficial ways (e.g., developing long-term solutions, engaging in positive reappraisal). Violent behavior was examined across years 1–3 (Time 1) and years 4–5 (Time 2; mean ages 18–19). CVE was longitudinally associated with greater violent behavior, adjusting for Time 1 levels of violent behavior. This association was significant only among adolescents with less effective coping strategies. Interventions targeting the enhancement of coping skills may be an effective method of reducing the impact of CVE on adolescent violent behavior. PMID:17687640

    Executive functioning deficits have been documented among congenital heart disease (CHD) survivors and may contribute to emotional distress. Little research has investigated the role of coping in this association. This study examined the role of coping in accounting for the association between self-reported executive function problems and internalizing symptoms among adolescents and emerging adults (AEAs), as well as young adults (YAs) with CHD. Participants included 74 AEA ( M age  = 19.32  ±  3.47 years, range 15-25 years) and 98 YA CHD survivors ( M age  = 32.00  ±  3.69 years, range 26-39 years), recruited from pediatric and adult outpatient cardiology clinics. Participants completed self-report measures of executive function problems, coping (primary control, secondary control, and disengagement coping), and internalizing symptoms. Lesion severity classification and functional impairment due to symptoms of heart failure were determined from medical chart review. Significant problems in executive function were reported by 5% of AEA and 13% of YA. Coping was not associated with executive function problems or internalizing symptoms for AEA. However, among YA, less use of adaptive coping strategies and more maladaptive coping responses was associated with both more executive function problems and internalizing symptoms. An indirect effect of executive function problems on internalizing symptoms via secondary control coping emerged for YA. Executive function problems may disrupt the ability to use important adaptive coping skills, such as cognitive reappraisal, positive thinking, and acceptance, thereby resulting in greater emotional distress among YA CHD survivors. © The Author(s) 2018.

    Little is known about the adaptive process and experiences of parents raising a child with an undiagnosed medical condition. The present study aims to assess how uncertainty, hope, social support, and coping efficacy contributes to adaptation among parents of children with an undiagnosed medical condition. Sixty-two parents of child affected by an undiagnosed medical condition for at least two years completed an electronically self-administered survey. Descriptive analysis suggested parents in this population had significantly lower adaptation scores when compared to other parents of children with undiagnosed medical conditions, and parents of children with a diagnosed intellectual and/or physical disability. Similarly, parents in this population had significantly lower hope, perceived social support and coping efficacy when compared to parents of children with a diagnosed medical condition. Multiple linear regression was used to identify relationships between independent variables and domains of adaptation. Positive stress response was negatively associated with emotional support (B = −0.045, p ≤ 0.05), and positively associated with coping efficacy (B = 0.009, p ≤ 0.05). Adaptive self-esteem was negatively associated with uncertainty towards one's social support (B = −0.248, p ≤ 0.05), and positively associated with coping efficacy (B = 0.007, p ≤ 0.05). Adaptive social integration was negatively associated with uncertainty towards one's social support (B-0.273, p ≤ 0.05), and positively associated with uncertainty towards child's health (B = 0.323, p ≤ 0.001), and affectionate support (B = 0.110, p ≤ 0.001). Finally, adaptive spiritual wellbeing was negatively associated with uncertainty towards one's family (B = −0.221, p ≤ 0.05). Findings from this study have highlighted the areas where parents believed additional support was required, and provided insight into factors that contribute to parental adaptation. PMID:28039658

    Purpose Throwing is a vigorous activity that generates large internal loads. There is limited evidence of the effect of these loads on bone adaptation. The aim of this study was to investigate the: 1) magnitude of bone adaptation within the midshaft humerus of female fast-pitch softball players and 2) influence of throwing mechanics (windmill vs. overhand throwing) on the magnitude of adaptation. Methods Midshaft humeral bone mass, structure and estimated strength were assessed via peripheral quantitative computed tomography in fast-pitch softball players (throwers; n=15) and matched controls (controls; n=15). The effect of throwing was examined by comparing dominant-to-nondominant differences in throwers to controls, while the influence of mechanics was determined by comparing dominant-to-nondominant differences in throwers who primarily play as pitcher (windmill thrower), catcher (overhand thrower) or fielder (overhand thrower). Results Throwers had greater dominant-to-nondominant difference in midshaft humeral bone mass, structure and estimated strength relative to controls (all P<0.05). The largest effect was for estimated torsional strength with throwers having a mean dominant-to-nondominant difference of 22.5% (range, 6.7% to 43.9%) compared to 4.4% (range, -8.3% to 17.5%) in controls (P<0.001). Throwing mechanics appeared to influence the magnitude of skeletal adaptation, with overhand throwers having more than double dominant-to-nondominant difference in midshaft humeral bone mass, structure and estimated strength than windmill throwers (all P<0.05). Conclusion Throwing induces substantial skeletal adaptation at the midshaft humerus of the dominant upper extremity. Throwing mechanics appears to the influence the magnitude of adaptation as catchers and fielders (overhand throwers) had twice as much adaptation as pitchers (windmill throwers). The latter finding may have implications for skeletal injury risk at the midshaft humerus in throwing athletes. PMID

    According to the Pan American Health Organization and the World Health Organization, in 2020, depression will become the second cause of disability worldwide. In Chile, anxiety and depressive disorders account for almost 28% of the total years of healthy life lost due to illness. This research seeks to explore a profile of social problem solving and coping present in people who suffer from anxious and depressive symptoms. The sample consisted of 1179 analogous Chilean participants (55.9% women), with a mean of 22.23 years (range between 18-48 years). The results suggest statistically significant differences for all social problem solving and coping strategies evaluated. Thus, if anxious or depressive symptoms increase, social problem solving or coping strategies become less adaptive.

  17. The Role of Adaptation in Body Load-Regulating Mechanisms During Locomotion

    Body loading is a fundamental parameter that modulates motor output during locomotion, and is especially important for controlling the generation of stepping patterns, dynamic balance, and termination of locomotion. Load receptors that regulate and control posture and stance in locomotion include the Golgi tendon organs and muscle spindles at the hip, knee, and ankle joints, and the Ruffini endings and the Pacinian corpuscles in the soles of the feet. Increased body weight support (BWS) during locomotion results in an immediate reorganization of locomotor control, such as a reduction in stance and double support duration and decreased hip, ankle, and knee angles during the gait cycle. Previous studies on the effect during exposure to increased BWS while walking showed a reduction in lower limb joint angles and gait cycle timing that represents a reorganization of locomotor control. Until now, no studies have investigated how locomotor control responds after a period of exposure to adaptive modification in the body load sensing system. The goal of this research was to determine the adaptive properties of body load-regulating mechanisms in locomotor control during locomotion. We hypothesized that body load-regulating mechanisms contribute to locomotor control, and adaptive changes in these load-regulating mechanisms require reorganization to maintain forward locomotion. Head-torso coordination, lower limb movement patterns, and gait cycle timing were evaluated before and after a 30-minute adaptation session during which subjects walked on a treadmill at 5.4 km/hr with 40% body weight support (BWS). Before and after the adaptation period, head-torso and lower limb 3D kinematic data were obtained while performing a goal directed task during locomotion with 0% BWS using a video-based motion analysis system, and gait cycle timing parameters were collected by foot switches positioned under the heel and toe of the subjects shoes. Subjects showed adaptive modification in

  18. Sclerostin's role in bone's adaptive response to mechanical loading.

    PubMed

    Galea, Gabriel L; Lanyon, Lance E; Price, Joanna S

    2017-03-01

    Mechanical loading is the primary functional determinant of bone mass and architecture, and osteocytes play a key role in translating mechanical signals into (re)modelling responses. Although the precise mechanisms remain unclear, Wnt signalling pathway components, and the anti-osteogenic canonical Wnt inhibitor Sost/sclerostin in particular, play an important role in regulating bone's adaptive response to loading. Increases in loading-engendered strains down-regulate osteocyte sclerostin expression, whereas reduced strains, as in disuse, are associated with increased sclerostin production and bone loss. However, while sclerostin up-regulation appears to be necessary for the loss of bone with disuse, the role of sclerostin in the osteogenic response to loading is more complex. While mice unable to down-regulate sclerostin do not gain bone with loading, Sost knockout mice have an enhanced osteogenic response to loading. The molecular mechanisms by which osteocytes sense and transduce loading-related stimuli into changes in sclerostin expression remain unclear but include several, potentially interlinked, signalling cascades involving periostin/integrin, prostaglandin, estrogen receptor, calcium/NO and Igf signalling. Deciphering the mechanisms by which changes in the mechanical environment regulate sclerostin production may lead to the development of therapeutic strategies that can reverse the skeletal structural deterioration characteristic of disuse and age-related osteoporosis and enhance bones' functional adaptation to loading. By enhancing the osteogenic potential of the context in which individual therapies such as sclerostin antibodies act it may become possible to both prevent and reverse the age-related skeletal structural deterioration characteristic of osteoporosis.

    How young people cope with stress is an important component of health and well-being since failure to deal with stress is very costly in social and emotional terms. In this study we examine the relationship between young people's declared failure to cope and the many coping styles that are reported concomitantly. The research questions addressed the extent to which positive and negative coping strategies co-exist in adolescent populations and whether the co-existence of these strategies confounds interpretation of the impact of coping on outcomes. A sample of 1219 adolescent school students was drawn from a wide range of 11 government and private coeducational schools situated in the three regions of metropolitan Melbourne, Australia. All participants completed the General form of the Adolescent Coping Scale in class groupings. Administration was conducted by a teacher who was also a registered psychologist. It was found that young people who were coping less successfully were those utilising more emotion-focused strategies. Further, students' use of emotion and problem-focused strategies was intercorrelated. This suggests that failure to cope triggers off increased coping activities of all kinds and that over-use of non-productive strategies interferes with the capacity to use productive coping.

    Acute myeloid leukemia (AML) is characterized by sudden onset, intensive treatment, a poor prognosis, and significant relapse risk. Quality of life (QOL) and well-being among AML survivors have been extensively studied during the 6 months of active treatment. However, it is not clear what survivors experience after active treatment. The purpose of our study was to explore how AML survivors describe their longer-term physical and psychosocial well-being and how they cope with these challenges. We conducted a prospective qualitative study and interviewed 19 adult participants (11 had completed treatment, 8 were receiving maintenance chemotherapy). Data were collected using semi-structured interviews that were audio-recorded and transcribed verbatim. The grounded theory approach was used for data analysis. A marked improvement in physical health was reported; however, psychosocial well-being was compromised by enduring emotional distress. A range of emotion- and problem-focused coping strategies were reported. Keeping one's mind off negative things through engaging in formal work or informal activities and seeking control were the two most commonly used coping strategies. Seeking social support for reassurance was also common. Problem-focused strategies were frequently described by the ongoing treatment group to manage treatment side effects. Although physical symptoms improved after completion of treatment, psychosocial distress persisted over longer period of time. In addition, essential needs of AML survivors shifted across survivorship as psychological burden gradually displaced physical concerns. The integral role of coping mechanisms in the adaptation process suggests a need for effective and ongoing psychological interventions.

    Cigarette smokers vulnerable to depression experience considerable difficulty in quitting smoking, possibly because they use smoking to manage negative affect and possess underdeveloped alternative coping skills for doing so. Efforts to adapt cognitive behavior therapy (CBT) of depression to the treatment of depression-vulnerable smokers have achieved inconsistent results. This research tested one possible explanation for these mixed results, the possibility that depression-vulnerable smokers are not actually deficient in the skills taught in CBT. Regular smokers with a history of major depression, but not currently in a depressive episode (n = 66), scored worse than did the never-depressed smokers (n = 68) on the Ways of Responding [WOR; Behav. Assess. 14 (1992) 93] test of skills for coping with negative moods and automatic thoughts. Results were similar in analyses using self-rated depression proneness, rather than interview-based diagnosis of past major depression, as the marker of depression vulnerability. Results were (nonsignificantly) stronger for Caucasian (n = 54) than for African-American (n = 73) smokers. Implications for future research on cognitive coping, CBT, and smoking are discussed.

  2. Perinatal grief following a termination of pregnancy for foetal abnormality: the impact of coping strategies.

    2013-12-01

    Pregnancy termination for foetal abnormality (TFA) can have significant psychological repercussions, but little is known about the coping strategies involved in dealing with TFA. This study examined the relationships between women's coping strategies and perinatal grief. A total of 166 women completed a survey online. Coping and perinatal grief were measured using the Brief COPE and Short Perinatal Grief Scales. Data were analysed through multiple regression analyses. Despite using mostly adaptive coping strategies, women's levels of grief were high and varied according to obstetric and termination variables. Grief was predicted by behavioural disengagement, venting, planning, religion, self-blame, being recently bereaved, being childless at the time of TFA, not having had children/being pregnant since TFA and uncertainty about the decision to terminate the pregnancy. Acceptance and positive reframing negatively predicted grief. Identifying women vulnerable to poor psychological adjustment and promoting coping strategies associated with lower levels of grief may be beneficial. This could be addressed through information provision and interventions such as Cognitive Behavioural Therapy or Acceptance and Commitment Therapy. © 2013 John Wiley & Sons, Ltd.

  3. Does age affect the stress and coping process? Implications of age differences in perceived control.

    PubMed

    Aldwin, C M

    1991-07-01

    The perceived controllability of situations is thought to influence the types of coping strategies used, and thus is important in adaptive processes. Elderly individuals are widely perceived to have less control over their environment than other adults. This lack of perceived control should have adverse affects on how they cope with stressful situations. However, most studies have shown that older adults differ little from younger adults in their approaches to coping with stress. This contradiction was investigated in a sample of 228 community-residing adults with a mean age of 42.16 (SD = 14.88). Path analysis revealed that appraisals and attributions do affect the use of coping strategies such as instrumental action and escapism in the expected directions, and age is negatively associated with perceived control. However, there was an independent and negative relationship between age and the reported use of escapist coping strategies, which mitigated the adverse effects of perceived lack of control. Neither age nor perceived controllability had direct effects on depression, but they had indirect effects through their influence on the use of coping strategies and perceived efficacy.

    This study examined whether intervention-induced changes in mother-child relationship quality and discipline led to short-term (6 months) and long-term (6 years) changes in children's coping processes in a sample of 240 youth aged 9-12 years when assessed initially. Data were from a randomized, experimental trial of a parenting-focused preventive intervention designed to improve children's post-divorce adjustment. Three-wave prospective mediational analyses revealed that intervention-induced improvements in relationship quality led to increases in coping efficacy at 6 months and to increases in coping efficacy and active coping at 6 years. Tests of the mediated effects were significant for all 3 indirect paths. Results are discussed in terms of pathways to adaptive coping and implications for the implementation of preventive interventions targeting coping. PMID:21291440

    Lafarge, Caroline; Mitchell, Kathryn; Fox, Pauline

    2017-09-01

    Research about termination for fetal abnormality (TFA) suggests that it is a traumatic event with potential negative psychological consequences. However, evidence also indicates that following traumatic events individuals may experience growth. Although TFA's negative psychological outcomes are well documented, little is known of the potential for growth following this event. Therefore, the study's objectives were to measure posttraumatic growth (PTG) post-TFA, examine the relationship between PTG, perinatal grief and coping, and determine the predictors of PTG. An online, retrospective survey was conducted with 161 women. Eligible participants were women over 18 who had undergone TFA. Participants were recruited from a support organisation. They completed the Brief COPE, Short Perinatal Grief Scale and Posttraumatic Growth Inventory. Data were analysed using regression analyses. Moderate levels of PTG were observed for "relating to others," "personal strengths" and "appreciation of life." "Positive reframing" was a significant predictor of PTG. Despite using mainly "adaptive" coping strategies, women's grief levels were high. "Adaptive" coping strategies such as, "positive reframing" are relevant to TFA. They may act as protective factors against distress and as foundations for growth, implicating that interventions such as Cognitive Behavioural Therapy, which aim to reframe women's experience, may be beneficial.

    2017-04-01

    The ways that college students cope with stress, particularly interpersonal stress, may be a critical factor in determining which students are at risk for impairing mental health disorders. Using a control-based model of coping, the present study examined associations between interpersonal stress, coping strategies, and symptoms. A total of 135 undergraduate students from 2 universities. Interpersonal stress, coping strategies, depression, anxiety, and somatization were assessed via self-report. Students reporting more interpersonal stress reported more depression, anxiety, and somatization, and they reported less use of engagement coping strategies and greater use of disengagement coping strategies. Engagement coping strategies accounted for a significant portion of the association between interpersonal stress and mental health symptoms. Unexpectedly, coping strategies did not moderate the association between stress and mental health symptoms. Interventions designed to improve students' coping strategies may be an effective way to reduce mental health problems on college campuses.

  7. The influence of emotional intelligence (EI) on coping and mental health in adolescence: divergent roles for trait and ability EI.

    PubMed

    Davis, Sarah K; Humphrey, Neil

    2012-10-01

    Theoretically, trait and ability emotional intelligence (EI) should mobilise coping processes to promote adaptation, plausibly operating as personal resources determining choice and/or implementation of coping style. However, there is a dearth of research deconstructing if/how EI impacts mental health via multiple coping strategies in adolescence. Using path analysis, the current study specified a series of multiple-mediation and conditional effects models to systematically explore interrelations between coping, EI, depression and disruptive behaviour in 748 adolescents (mean age = 13.52 years; SD = 1.22). Results indicated that whilst ability EI influences mental health via flexible selection of coping strategies, trait EI modifies coping effectiveness; specifically, high levels of trait EI amplify the beneficial effects of active coping and minimise the effects of avoidant coping to reduce symptomotology. However, effects were selective with respect to coping style and outcome. Implications for interventions are discussed alongside directions for future research.

    Herpes simplex virus entry into cells requires the binding of envelope glycoprotein D (gD) to an entry receptor. Depending on the cell, entry occurs by different mechanisms, including fusion at the cell surface or endocytosis. Here we examined the entry mechanism through a non-HSV receptor mediated by a soluble bi-specific adapter protein composed of recognition elements for gD and the EGF receptor (EGFR). Virus entered into endosomes using either EGF or an EGFR-specific single chain antibody (scFv) for receptor recognition. Infection was less efficient with the EGF adapter which could be attributed to its weaker binding to a viral gD.more » Infection mediated by the scFv adapter was pH sensitive, indicating that gD-EGFR bridging alone was insufficient for capsid release from endosomes. We also show that the scFv adapter enhanced infection of EGFR-expressing tumor tissue in vivo. Our results indicate that adapters may retarget HSV infection without drastically changing the entry mechanism.« less

    The ways in which a family copes with the physical and psychosocial burdens of sickle cell disease (SCD) can influence child and family functioning. However, few studies have examined SCD-related stressors beyond pain or how children and parents cope with these stressors. This study aimed to describe child coping and parent attempts to help their children cope (i.e., coping assistance) with a range of SCD stressors by using a triangulated mixed methods design. We also explored convergence between findings from qualitative interviews and quantitative coping inventories. Fifteen children (aged 6 – 14) with SCD and their parents (N = 15) completed semi-structured interviews and self-report measures to assess SCD-related stressors, coping, and coping assistance strategies. Findings indicate that children experience numerous stressors related to SCD and its treatment, including but not limited to pain. To manage these stressors, families employ a range of approach- and avoidance-oriented coping strategies. Quantitative and qualitative assessments provided complementary and unique contributions to understanding coping processes among children with SCD and their parents. Examining a broad range of stressors and integrating multiple assessment methods helps improve our understanding of coping with pediatric SCD, which may inform clinical practice and family-focused intervention development.

    The present study compared people with depressive symptoms and people without depressive symptoms with reference to their coping styles, level of aggression and interpersonal conflicts. A purposive sample of 128 people (64 depressed and 64 normal controls)was selected from four different teaching hospitals of Lahore. Both the groups were matched on four demographic levels i.e. age, gender, education and monthly income. Symptom Checklist-R was used to screen out depressed and non-depressed people. The Brief COPE, the Aggression Questionnaire and the Bergen Social Relationship Scale were used to assess coping styles, aggression and interpersonal conflicts respectively. The Independent t-test was used to compare the groups. Binary logistic Regression was also carried out to predict the role of research variables in causing depression. The results showed that level of aggression and interpersonal conflict was significantly more in people with depressive symptoms as compared to control group. On the other hand control group was using more adaptive coping styles than people with depressive symptoms but no difference was found in the use of maladaptive coping styles. The present findings revealed that coping styles, aggression and interpersonal conflicts play important role in depression. Therefore, these dimensions must be considered while dealing with the depressive patients. Implications for preventive work are also discussed in the light of previous researches.

    Stressful life events are common among youth students and may induce psychological problems and even suicidal behaviors in those with poor coping skills. This study aims to assess the influence of stressful life events and coping skills on risk for suicidal behavior and to elucidate the underlying mechanism using a large sample of university students in China. 5972 students, randomly selected from 6 universities, completed the questionnaire survey. Logistic regression analysis was performed to estimate the effect of stressful life events and coping skills on risk for suicidal behavior. Bayesian network was further adopted to probe their probabilistic relationships. Of the 5972 students, 7.64% reported the presence of suicidal behavior (attempt or ideation) within the past one year period. Stressful life events such as strong conflicts with classmates and a failure in study exam constituted strong risk factors for suicidal behavior. The influence of coping skills varied according to the strategies adapted toward problems with a high score of approach coping skills significantly associated with a reduced risk of suicidal behavior. The Bayesian network indicated that the probability of suicidal behavior associated with specific life events was to a large extent conditional on coping skills. For instance, a stressful experience of having strong conflicts with classmates could result in a probability of suicidal behavior of 21.25% and 15.36% respectively, for female and male students with the score of approach coping skills under the average. Stressful life events and deficient coping skills are strong risk factors for suicidal behavior among youth students. The results underscore the importance of prevention efforts to improve coping skills towards stressful life events.

    Individual differences in behaviour and physiological responses to stress are associated with evolutionary adaptive variation and thus raw material for evolution. In farmed animals, the interest in consistent trait associations, i.e. coping styles, has increased dramatically over the last years. However, one of limitations of the available knowledge, regarding the temporal consistency, is that it refers always to short-term consistency (usually few weeks). The present study used an escape response during a net restraining test, previously shown to be an indicative of coping styles in seabream, to investigate long-term consistency of coping styles both over time and during different life history stages. Results showed both short-term (14 days) consistency and long-term (8 months) consistency of escape response. However, we did not found consistency in the same behaviour after sexual maturation when the restraining test was repeated 16, 22 and 23 months after the first test was performed. In conclusion, this study showed consistent behaviour traits in seabream when juveniles, and a loss of this behavioural traits when adults. Therefore, these results underline that adding a life story approach to data interpretation as an essential step forward towards coping styles foreground. Furthermore, a fine-tuning of aquaculture rearing strategies to adapt to different coping strategies may need to be adjusted differently at early stages of development and adults to improve the welfare of farmed fish.

  16. Cell Cycle Regulators Guide Mitochondrial Activity in Radiation-Induced Adaptive Response

    2014-01-01

    Abstract Significance: There are accruing concerns on potential genotoxic agents present in the environment including low-dose ionizing radiation (LDIR) that naturally exists on earth's surface and atmosphere and is frequently used in medical diagnosis and nuclear industry. Although its long-term health risk is being evaluated and remains controversial, LDIR is shown to induce temporary but significant adaptive responses in mammalian cells and animals. The mechanisms guiding the mitochondrial function in LDIR-induced adaptive response represent a unique communication between DNA damage and cellular metabolism. Elucidation of the LDIR-regulated mitochondrial activity may reveal new mechanisms adjusting cellular function to cope with hazardous environmental stress. Recent Advances: Key cell cycle regulators, including Cyclin D1/CDK4 and Cyclin B1/cyclin-dependent kinase 1 (CDK1) complexes, are actively involved in the regulation of mitochondrial functions via phosphorylation of their mitochondrial targets. Accumulating new evidence supports a concept that the Cyclin B1/CDK1 complex acts as a mediator in the cross talk between radiation-induced DNA damage and mitochondrial functions to coordinate cellular responses to low-level genotoxic stresses. Critical Issues: The LDIR-mediated mitochondrial activity via Cyclin B1/CDK1 regulation is an irreplaceable network that is able to harmonize vital cellular functions with adjusted mitochondrial metabolism to enhance cellular homeostasis. Future Directions: Further investigation of the coordinative mechanism that regulates mitochondrial activities in sublethal stress conditions, including LDIR, will reveal new insights of how cells cope with genotoxic injury and will be vital for future targeted therapeutic interventions that reduce environmental injury and cancer risk.

    Successful adaptation to the environment requires strategies to cope with stressful situations. The aim of this study was to examine the role of stressful life events in coping strategies during early adolescence. A representative sample of 2464 adolescents in Norway were assessed at two time-points, one year apart (i.e., at T1, mean age 13.7 years, and at T2, mean age 14.9 years), with identical questionnaires. The participation rate was 88.3% at T1. Stressful life events and daily hassles were measured by questionnaires constructed for this study. Coping with stress was measured by a modified version of the Coping Inventory for Stressful Situations (CISS), which measures three coping dimensions: emotional, task and avoidance coping. Depressive symptoms were assessed by the Mood and Feelings Questionnaire (MFQ). Standard multiple linear regression methods were applied. Different domains of stressful life events were associated with the coping strategies, and these relationships differed at various time-points by gender. In sum, school stress and stressful life events in one's network (network stress) was associated with coping strategies more strongly among girls, while family and miscellaneous stress showed a stronger association among boys. These relationships were partly mediated by depressive symptom levels, more strongly in cross-sectional than in longitudinal analyses. However, daily hassles seemed to represent smaller events of no importance in coping strategies. In preventive work, reducing stressful events, treating depression and teaching healthier coping strategies are important.

    In studying coping processes, there is often a focus on individual coping while dyadic processes in couples are seldom addressed. Therefore we present here data with the Hungarian version of the Dyadic Coping Inventory (DCI) that was developed to assess dyadic forms of coping (e.g., stress communication, support, delegated and negative coping). 473 adult participants, living in committed relationships (176 male and 296 female, aged 34,0 +/- 11,9 years) were involved in a questionnaire study. Along with the Hungarian version of the Dyadic Coping Inventory we assessed satisfaction with life (SWLS) and marital satisfaction (Marital Stress Scale). Subscales of the Dyadic Coping Inventory were found reliable and the expected factor structure for both the dyadic coping of oneself and the partner were replicable. Moreover, specific forms of dyadic coping accounted for significant amount of explained variance in life satisfaction (31,8 and 27,7% for male and female respondents) and marital satisfaction (1,8 and 48,5%). Results imply possible gender differences, since marital satisfaction of women was negatively predicted both by negative coping of oneself and the partner (betas=-0,174 and -0,152), and positively by the support of the partner and the evaluation of the common dyadic coping (betas= 0,255 and 0,187), whereas there was only one significant link in male respondents, supportive coping of oneself (beta= 0,320). Results show that 1. the Hungarian version of the DCI is a reliable and valid measure, and 2. there may be specific gender differences in dyadic coping that has to be considered when planning further research, training programs and therapeutic interventions for couples.

    The current study aims to determine whether elderly Holocaust survivors are affected differently from non-survivors by the adversity of aging and cancer. Holocaust survivors and non-survivors suffering from cancer, were assessed tapping PTSD, psychiatric symptomatology, psychosocial adjustment to illness and coping with the aftermath of the Holocaust. Findings indicate a significant difference between survivors and non-survivors in post-traumatic symptoms and their intensity, survivors endorsing significantly more PTSD symptoms. Survivors were classified into 3 sub-groups, namely "Victims," "Fighters," and "Those who made it". "Victims" reported the highest percentage of persons who met PTSD, psychiatric symptomatology and difficulty coping with the problems of old age. The diversity of responses points to heterogeneity of long-term adaptation and adjustment among Holocaust survivors and similar response to subsequent adversity.

    To describe how patients adapt to living with a mechanical aortic heart valve. Aortic valve replacement with a mechanical prosthesis is preferred for patients with life expectancy of more than 10 years as they are more durable than bioprosthetic valves. Mechanical valves have some disadvantages, such as higher risk of thrombosis and embolism, increased risk of bleeding related to lifelong oral anticoagulation treatment and noise from the valve. An explorative design with a phenomenographic approach was employed. An explorative design with a phenomenographic approach was applied. Interviews were conducted over 4 months during 2010-2011 with 20 strategically sampled patients, aged 24-74 years having undergone aortic valve replacement with mechanical prosthesis during the last 10 years. Patients adapted to living with a mechanical aortic heart valve in four ways: 'The competent patient' wanted to stay in control of his/her life. 'The adjusted patient' considered the implications of having a mechanical aortic valve as part of his/her daily life. 'The unaware patient' was not aware of warfarin-diet-medication interactions. 'The worried patient' was bothered with the oral anticoagulation and annoyed by the sound of the valve. Patients moved between the different ways of adapting. The oral anticoagulation therapy was considered the most troublesome consequence, but also the sound of the valve was difficult to accept. Patient counselling and adequate follow-up can make patients with mechanical aortic heart valves more confident and competent to manage their own health. We recommend that patients should participate in a rehabilitation programme following cardiac surgery. © 2013 Blackwell Publishing Ltd.

    Patterns of psychological coping are associated with a variety of health outcomes but the underlying pathways are not yet established. The purpose of this study was to assess the relationship between salivary cortisol output over the course of a day and coping style. Data were available from 350 men and 192 women with an average age of 60.9 years. Participants were drawn from the Whitehall II cohort, and had no history of cardiovascular disease. Individuals who were taking medication that might affect cortisol levels were also excluded. Saliva samples were provided on waking, then 0.5, 2.5, 8 and 12h after waking, and just before the participant went to sleep. Coping style was measured with a standard instrument, the COPE, and data were factor analysed to generate three factors: seeking social support, problem engagement and problem avoidance. The relationships between these factors and the cortisol awakening response (CAR), the slope of cortisol change over the day and total cortisol output over the day (excluding the waking period) were assessed using multiple linear regression. Cortisol output over the day was inversely associated with coping with stress by seeking social support (p=0.034) and by problem engagement (p=0.003), independently of age, gender, body mass index, smoking, depression, self-rated health, time of waking and income. Individuals who coped by problem engagement and seeking support had lower cortisol levels. Additionally, gender, BMI, smoking, self-rated health and time of waking were independently related to cortisol output over the day. There were no significant associations between coping and the CAR or cortisol slope over the day. The results indicate that adaptive coping styles are related to low levels of cortisol over the day, suggesting that neuroendocrine pathways may partly mediate relationships between psychological coping and health.

  3. Physiological adaptation of the growth-restricted fetus.

    PubMed

    Maršál, Karel

    2018-05-01

    The growth-restricted fetus in utero is exposed to a hostile environment and suffers undernutrition and hypoxia. To cope with the stress, the fetus changes its physiological functions. These adaptive changes aid intrauterine survival; however, they can lead to permanent functional and structural changes that can contribute to the development of serious chronic diseases later in life. Epigenetic mechanisms are an important part of the pathophysiological processes behind this "developmental origin of adult diseases." The dominant cardiovascular adaptive change is the redistribution of blood flow in hypoxic fetuses, with preferential supply of blood to the fetal brain, myocardium, and adrenal glands. The proportion of blood from the umbilical vein to the ductus venosus and foramen ovale increases, which increases the cardiac output of the left heart ventricle. The increased perfusion of fetal brain can be followed with Doppler ultrasound as increased diastolic velocities and decreased pulsatility index in the middle cerebral artery. Copyright © 2018.

    Existing research on trans individuals has primarily focused on their negative experiences and has disproportionately examined coming-out processes and identity development stages. Using a grounded theory approach, this qualitative study sought to examine facilitative coping processes among trans-identified individuals. Facilitative coping was operationalized as processes whereby individuals seek social support, learn new skills, change behaviors to positively adapt, and find alternative means to seek personal growth and acceptance. The sample included 15 participants who self-identified with a gender identity that was different from their assigned sex at birth. Results yielded a total of nine overarching themes: Accepting Support from Others, Actions to Increase Protection, Active Engagement Throughout the Transition Process, Actively Seeking Social Interactions, Engaging in Exploration, Internal Processes Leading to Self-Acceptance, Self-Efficacy, Shifts Leading to Embracing Change and Flexibility, and Utilization of Agency. Based on the analysis, a theoretical model emerged that highlighted the importance of internal and external coping processes in facilitating gender identity development and navigating stressors among trans individuals. Clinical implications focusing on how to implement facilitative coping processes are discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    This study examines whether intervention-induced changes in mother-child relationship quality and discipline led to short-term (6 months) and long-term (6 years) changes in children's coping processes in a sample of 240 youth aged 9-12 years when assessed initially. Data were from a randomized, experimental trial of a parenting-focused preventive intervention designed to improve children's postdivorce adjustment. Three-wave prospective mediational analyses revealed that intervention-induced improvements in relationship quality led to increases in coping efficacy at 6 months and to increases in coping efficacy and active coping at 6 years. Tests of the mediated effects were significant for all 3 indirect paths. Results are discussed in terms of pathways to adaptive coping and implications for the implementation of preventive interventions targeting coping. © 2011 The Authors.

  6. Short-term saccadic adaptation in the macaque monkey: a binocular mechanism

    Saccadic eye movements are rapid transfers of gaze between objects of interest. Their duration is too short for the visual system to be able to follow their progress in time. Adaptive mechanisms constantly recalibrate the saccadic responses by detecting how close the landings are to the selected targets. The double-step saccadic paradigm is a common method to simulate alterations in saccadic gain. While the subject is responding to a first target shift, a second shift is introduced in the middle of this movement, which masks it from visual detection. The error in landing introduced by the second shift is interpreted by the brain as an error in the programming of the initial response, with gradual gain changes aimed at compensating the apparent sensorimotor mismatch. A second shift applied dichoptically to only one eye introduces disconjugate landing errors between the two eyes. A monocular adaptive system would independently modify only the gain of the eye exposed to the second shift in order to reestablish binocular alignment. Our results support a binocular mechanism. A version-based saccadic adaptive process detects postsaccadic version errors and generates compensatory conjugate gain alterations. A vergence-based saccadic adaptive process detects postsaccadic disparity errors and generates corrective nonvisual disparity signals that are sent to the vergence system to regain binocularity. This results in striking dynamical similarities between visually driven combined saccade-vergence gaze transfers, where the disparity is given by the visual targets, and the double-step adaptive disconjugate responses, where an adaptive disparity signal is generated internally by the saccadic system.

  7. Novel pathogenetic mechanisms and structural adaptations in ischemic mitral regurgitation.

    PubMed

    Silbiger, Jeffrey J

    2013-10-01

    Ischemic mitral regurgitation (MR) is a common complication of myocardial infarction thought to result from leaflet tethering caused by displacement of the papillary muscles that occurs as the left ventricle remodels. The author explores the possibility that left atrial remodeling may also play a role in the pathogenesis of ischemic MR, through a novel mechanism: atriogenic leaflet tethering. When ischemic MR is hemodynamically significant, the left ventricle compensates by dilating to preserve forward output using the Starling mechanism. Left ventricular dilatation, however, worsens MR by increasing the mitral valve regurgitant orifice, leading to a vicious cycle in which MR begets more MR. The author proposes that several structural adaptations play a role in reducing ischemic MR. In contrast to the compensatory effects of left ventricular enlargement, these may reduce, rather than increase, its severity. The suggested adaptations involve the mitral valve leaflets, the papillary muscles, the mitral annulus, and the left ventricular false tendons. This review describes the potential role each may play in reducing ischemic MR. Therapies that exploit these adaptations are also discussed. Copyright © 2013 American Society of Echocardiography.

    The purpose of this systematic review was to examine coping strategies that people with multiple sclerosis use, and to identify factors that influence their coping pattern. This systematic review followed the Joanna Briggs Institute guidelines for synthesizing descriptive quantitative research. The following databases were searched from the inception of databases until December 2016: Ovid (Medline, Embase, CINAHL, and PsycINFO), Science Direct, Web of Science, and Scopus. Manual search was also conducted from the reference lists of retrieved articles. Findings related to the patterns of coping with multiple sclerosis and factors influencing coping with multiple sclerosis were extracted and synthesized. The search of the database yielded 455 articles. After excluding duplicates (n = 341) and studies that did not meet the inclusion criteria (n = 27), 71 studies were included in the full-text review. Following the full-text, a further 21 studies were excluded. Quality appraisal of 50 studies was completed, and 38 studies were included in the review. Synthesis of findings indicated that people with multiple sclerosis use emotional and avoidance coping strategies more than other types of coping, particularly in the early stages of the disease. In comparison to the general population, people with multiple sclerosis were less likely to use active coping strategies and used more avoidance and emotional coping strategies. The pattern of coping with multiple sclerosis was associated with individual, clinical and psychological factors including gender, educational level, clinical course, mood and mental status, attitude, personality traits, and religious beliefs. The findings of this review suggest that considering individual or disease-related factors could help healthcare professionals in identifying those less likely to adapt to multiple sclerosis. This information could also be used to provide client-centered rehabilitation for people living with multiple

    Background The Pacific oyster, Crassostrea gigas, has developed special mechanisms to regulate its osmotic balance to adapt to fluctuations of salinities in coastal zones. To understand the oyster’s euryhaline adaptation, we analyzed salt stress effectors metabolism pathways under different salinities (salt 5, 10, 15, 20, 25, 30 and 40 for 7 days) using transcriptome data, physiology experiment and quantitative real-time PCR. Results Transcriptome data uncovered 189, 480, 207 and 80 marker genes for monitoring physiology status of oysters and the environment conditions. Three known salt stress effectors (involving ion channels, aquaporins and free amino acids) were examined. The analysis of ion channels and aquaporins indicated that 7 days long-term salt stress inhibited voltage-gated Na+/K+ channel and aquaporin but increased calcium-activated K+ channel and Ca2+ channel. As the most important category of osmotic stress effector, we analyzed the oyster FAAs metabolism pathways (including taurine, glycine, alanine, beta-alanine, proline and arginine) and explained FAAs functional mechanism for oyster low salinity adaptation. FAAs metabolism key enzyme genes displayed expression differentiation in low salinity adapted individuals comparing with control which further indicated that FAAs played important roles for oyster salinity adaptation. A global metabolic pathway analysis (iPath) of oyster expanded genes displayed a co-expansion of FAAs metabolism in C. gigas compared with seven other species, suggesting oyster’s powerful ability regarding FAAs metabolism, allowing it to adapt to fluctuating salinities, which may be one important mechanism underlying euryhaline adaption in oyster. Additionally, using transcriptome data analysis, we uncovered salt stress transduction networks in C. gigas. Conclusions Our results represented oyster salt stress effectors functional mechanisms under salt stress conditions and explained the expansion of FAAs metabolism pathways as

    2009-12-01

    disaster research and emergency management communities have shown over that early warnings of impending hazards need to be complemented by information on the risks actually posed by the hazards (including those resulting from low levels of preparedness), existing strategies on the ground, and likely pathways to mitigate the loss and damage in the particular context in which they arise. Effective adaptations require information for long-term infrastructural planning and as critically deliberative mechanisms to structure learning and redesign in the face of emergent problems. Adaptation tends to be reactive, unevenly distributed, and focused on coping rather than preventing problems. Reduction in vulnerability will require anticipatory deliberative processes focused on incorporating adaptation into long-term municipal and public service planning, including energy, water, and health services, in the face of changing climate-related risks combined with ongoing changes in population, land use and development patterns.

  13. The plasma membrane transport systems and adaptation to salinity.

    Salt stress represents one of the environmental challenges that drastically affect plant growth and yield. Evidence suggests that glycophytes and halophytes have a salt tolerance mechanisms working at the cellular level, and the plasma membrane (PM) is believed to be one facet of the cellular mechanisms. The responses of the PM transport proteins to salinity in contrasting species/cultivars were discussed. The review provides a comprehensive overview of the recent advances describing the crucial roles that the PM transport systems have in plant adaptation to salt. Several lines of evidence were presented to demonstrate the correlation between the PM transport proteins and adaptation of plants to high salinity. How alterations in these transport systems of the PM allow plants to cope with the salt stress was also addressed. Although inconsistencies exist in some of the information related to the responses of the PM transport proteins to salinity in different species/cultivars, their key roles in adaptation of plants to high salinity is obvious and evident, and cannot be precluded. Despite the promising results, detailed investigations at the cellular/molecular level are needed in some issues of the PM transport systems in response to salinity to further evaluate their implication in salt tolerance.

    2007-11-01

    The aim of this study was to examine stressors, coping, and coping effectiveness as a function of gender, type of sport, and skill. The sample consisted of 749 undergraduate athletes (455 males, 294 females) aged 18-38 years (mean= 19.8 years). Skill was classified as international/national, county, university, and club standard. Participants completed a stressor and coping concept map (Novak & Gowin, 1984). The results revealed gender, type of sport, and skill differences in relation to stressor frequencies, coping strategy deployment, and coping effectiveness. In contrast to previous research, females used a variety of problem-focused (e.g. planning, communication, technique-orientated coping) strategies more frequently than males. Team sport athletes reported a variety of sport-specific stressors relating to the demands of playing in a team environment. The group of national/international athletes reported using more planning, blocking, and visualization, and also reported that their coping was more effective than that of less-skilled athletes.

    1998-12-01

    This study examined the role of coping strategies and family relationships in mitigating the negative effect of work stress on nurses. The findings indicated that nurses who adapted to work stress with high job satisfaction were more inclined to adopt approach coping methods (problem orientation, ability enhancement, and change of perspective) than those who reported low job satisfaction under high work stress. The stress-resistant nurses were also distinguished by a less frequent use of defensive or avoidance coping in handling of their emotional reactions to stress. They perceived greater family support than did the distressed nurses. Implications of the findings and limitation of the study were discussed.

    Purpose The purpose of this review was to examine the conceptualization and measurement of coping in adolescent research. Design A review of the literature published and abstracted in four scientific databases was undertaken between July 2008 and June 2009 with the following key words: adolescent(s), cope/coping, stress(ors), and adaptation/psychological. Methods A total of 367 articles were initially identified, and review of published abstracts yielded 104 empirical articles to retrieve and examine more closely for inclusion. Criteria for inclusion in the review were that the study (a) measured coping, (b) presented original data, (c) primarily targeted adolescent participants, (d) was reported in English, and (e) was published between 1998 and June 2009. Fifty-nine subsequent articles were organized using a matrix approach that facilitated cross-study comparisons of purpose, sample, and dependent variables. Findings Fewer than half of the studies reviewed included a specific statement defining coping. Instead, many authors described coping in the context of stress response by identifying particular types or ways of coping or naming specific coping strategies used. The theoretical frameworks guiding examination of coping varied across studies. A range of measures, congruent with adolescent developmental processes, were used to assess adolescent coping. A wide range of stress-related risks or conditions were examined, including psychological stressors such as eating disorders, suicidal ideation, and depression; physical stressors such as chronic illness, HIV infection, sports participation, violence, or sexual abuse; familial stressors such as domestic violence or interparental conflict; social stressors such as romantic relationships or difficulties in settings such as school, prison, or a homeless shelter; and societal stressors such as discrimination. Conclusions Coping is an important construct in understanding how adolescents react to the extensive stressors

    PubMed

    2012-08-01

    To develop a framework of decision making and coping in healthcare that describes the twin processes of appraisal and coping faced by patients making preference-sensitive healthcare decisions. We briefly review the literature for decision making theories and coping theories applicable to preference-sensitive decisions in healthcare settings. We describe first decision making, then coping and finally attempt to integrate these processes by building on current theory. Deliberation in healthcare may be described as a six step process, comprised of the presentation of a health threat, choice, options, preference construction, the decision itself and consolidation post-decision. Coping can be depicted in three stages, beginning with a threat, followed by primary and secondary appraisal and ultimately resulting in a coping effort. Drawing together concepts from prominent decision making theories and coping theories, we propose a multidimensional, interactive framework which integrates both processes and describes coping in deliberation. The proposed framework offers an insight into the complexity of decision making in preference-sensitive healthcare contexts from a patient perspective and may act as theoretical basis for decision support.

    Food allergy is major public health concern affecting nearly 15 million Americans and 80 million Europeans. Risk of anaphylaxis and implications for social activities affect patients' quality of life and psychological well-being. We previously found that young patients reported higher levels of alexithymia (difficulty in recognizing and expressing emotions) compared with healthy peers and may influence affect, management style and clinical outcomes. This study aimed to explore links between coping strategies, alexithymia and anxiety among food-allergic adolescents and young adults. Ninety-two patients with IgE-mediated food allergy (mean age 18.6 years) completed Coping Orientation to Problems Experienced Inventory, Toronto Alexithymia Scale and Trait Anxiety subscale of State-Trait Anxiety Inventory. Multivariate analyses of variance assessed differences and associations between subgroups on the scales. Significant differences found between alexithymia levels in coping style were explained by Avoidance strategies. 'Avoidance' had the highest contribution in explaining alexithymia, followed by trait anxiety, age, anaphylaxis and social support. Respondents with higher alexithymia use avoidance as coping strategy over and above other coping strategies such as problem-solving and positive thinking, are younger, will have experienced anaphylaxis and will have lower social support. Recognizing the specific role of affect regulation in health behaviours may constitute an important step in supporting patients to explore more adaptive strategies. © 2016 John Wiley & Sons A/S.

    Listeners show a remarkable ability to quickly adjust to degraded speech input. Here, we aimed to identify the neural mechanisms of such short-term perceptual adaptation. In a sparse-sampling, cardiac-gated functional magnetic resonance imaging (fMRI) acquisition, human listeners heard and repeated back 4-band-vocoded sentences (in which the temporal envelope of the acoustic signal is preserved, while spectral information is highly degraded). Clear-speech trials were included as baseline. An additional fMRI experiment on amplitude modulation rate discrimination quantified the convergence of neural mechanisms that subserve coping with challenging listening conditions for speech and non-speech. First, the degraded speech task revealed an "executive" network (comprising the anterior insula and anterior cingulate cortex), parts of which were also activated in the non-speech discrimination task. Second, trial-by-trial fluctuations in successful comprehension of degraded speech drove hemodynamic signal change in classic "language" areas (bilateral temporal cortices). Third, as listeners perceptually adapted to degraded speech, downregulation in a cortico-striato-thalamo-cortical circuit was observable. The present data highlight differential upregulation and downregulation in auditory-language and executive networks, respectively, with important subcortical contributions when successfully adapting to a challenging listening situation.

    2015-01-01

    Female veterans, the fastest growing segment in the military, have unique pre-military histories and military experiences that are associated with post-military physical and mental health service needs. Successful treatment is contingent on a clearer understanding of the processes underlying these experiences. Data from 20 female veterans who served post–Gulf War were analyzed to generate a substantive theory of the process of women who entered, served in, and transitioned out of the military. Coping with transitions emerged as the basic psychosocial process used by female veterans. The Coping with transitions process is comprised of seven categories: Choosing the Military, Adapting to the Military, Being in the Military, Being a Female in the Military, Departing the Military, Experiencing Stressors of Being a Civilian, and Making Meaning of Being a Veteran-Civilian. The results of this study provide a theoretical description of the process female veterans experience when transitioning from a civilian identity, through military life stressors and adaptations, toward gaining a dual identity of being a veteran-civilian.

    Various CAD/CAM processes are commercially available to manufacture zirconia copings. Comparative data on their performance in terms of fit are needed. The purpose of this in vitro study was to compare the internal and marginal fit of single tooth zirconia copings manufactured with a CAD/CAM process (Procera; Nobel Biocare) and a mechanized manufacturing process (Ceramill; Amann Girrbach). Abutments (n=20) prepared in vivo for ceramic crowns served as a template for manufacturing both Procera and Ceramill zirconia copings. Copings were manufactured and cemented (Clearfil Esthetic Cement; Kuraray) on epoxy replicas of stone cast abutments. Specimens were sectioned. Nine measurements were performed for each coping. Over- and under-extended margins were evaluated. Comparisons between the 2 processes were performed with a generalized linear mixed model (α=.05). Internal gap values between Procera and Ceramill groups were not significantly different (P=.13). The mean marginal gap (SD) for Procera copings (51(50) μm) was significantly smaller than for Ceramill (81(66) μm) (P<.005). The percentages of over- and under-extended margins were 43% and 57% for Procera respectively, and 71% and 29% for Ceramill. Within the limitations of this in vitro study, the marginal fit of Procera copings was significantly better than that of Ceramill copings. Furthermore, Procera copings showed a smaller percentage of over-extended margins than did Ceramill copings. Copyright © 2011 The Editorial Council of the Journal of Prosthetic Dentistry.

    Cognitive behavior therapy for depression has been adapted for use in cigarette smoking cessation groups. CBT appears to be an effective treatment, though results are mixed as to whether it is especially helpful for smokers vulnerable to depression, and little is known about what mediates its effects. Based on the hypothesis that CBT works by way of teaching compensatory skills for coping with negative thinking and emotions, this study compared CBT with a time-matched comparison condition incorporating health education and scheduled, reduced smoking. There was a nonsignificant trend favoring CBT in achieving abstinence, but CBT did not enhance smokers' compensatory coping skills. Discussion focuses on the need to examine a wide range of possible mediating variables in future research on CBT for smoking cessation.

    In occupational settings, burnout is a common response to chronic exposure stressors and has been frequently documented in formal caregivers (i.e. paid psychiatric staff). However, the literature is limited on reports of burnout among informal caregivers and particularly within early psychosis groups. The current study sought to investigate reports of burnout in carers of young adults treated within a specialist early psychosis service and links with key appraisals reported about the illness and coping. Seventy-two carers completed the Maslach Burnout Inventory along with self-report measures of coping styles and illness beliefs. Seventy-eight per cent of carers reported high burnout in at least one of the three key burnout markers (i.e. emotional exhaustion, depersonalization or low personal accomplishment). Seven per cent of carers met full criteria for high burnout across all the three domains. A carer's belief about the negative consequences of the illness for themselves was a significant predictor of emotional exhaustion and depersonalization. Low personal accomplishment was linked to a carer's less optimistic beliefs about the illness timeline and fewer reports of adaptive coping. The results provide preliminary support for the importance of asking carers in the early illness phase about their experiences of caregiving. Targeted assessment may serve as a helpful tool to identify and intervene with carers in need of additional support with stress management, use of adaptive coping strategies, and balanced recovery focused information about psychosis. © 2015 Wiley Publishing Asia Pty Ltd.

    To study the relevance between cancer related fatigue and coping styles in breast cancer patients after chemotherapy. A survey was conducted in 396 patients with breast cancer after chemotherapy on cancer related fatigue scale and Jalowiec coping scale, and the relation was analyzed. The rate of overall fatigue in breast cancer patients was 96.97%, mostly moderate fatigue. The rate of fatigue dimensions from high to low was physical fatigue, feeling fatigue and cognitive fatigue, respectively. The score of coping styles in patients with breast cancer after chemotherapy from high to low was optimistic coping, facing bravely, support seeking, self-reliance, emotional catharsis, avoidance, fatalism, and conservation. The most widely used coping style was optimistic coping style, and the least was emotional catharisis. There was a positive correlation between coping style of emotional catharsis and cancer related fatigue of all dimensions (P<0.01). There was a negative correlation between emotional fatigue and optimistic,facing bravely, support seeking, self-reliance, or conservation (P<0.05). There was also a negative correlation between physical fatigue and optimistic or support seeking (P<0.05), but there was a positive correlation between avoidance or fatalism and the dimensions of general fatigue, physical fatigue, and cognitive fatigue (P<0.05). There is prevalent cancer related fatigue in patients with breast cancer after chemotherapy. We should guide the patients to more active coping styles, to enhance the ability of psychological adaption in patients, reduce cancer related fatigue, and improve the quality of life.

    2011-01-01

    Background An exclusive focus on individual or family coping strategies may be inadequate for people whose major point of concern may be collective healing on a more communal level. Methods To our knowledge, the current study is the first to make use of ethnographic fieldwork methods to investigate this type of coping as a process in a natural setting over time. Participant observation was employed within a Tamil NGO in Norway between August 2006 and December 2008. Results Tamil refugees in Norway co-operated to appraise their shared life situation and accumulate resources communally to improve it in culturally meaningful ways. Long term aspirations were related to both the situation in the homeland and in exile. However, unforeseen social events created considerable challenges and forced them to modify and adapt their coping strategies. Conclusions We describe a form of coping previously not described in the scientific literature: Communal proactive coping strategies, defined as the process by which group members feel collectively responsible for their future well-being and co-operate to promote desired outcomes and prevent undesired changes. The study shows that proactive coping efforts occur in a dynamic social setting which may force people to use their accumulated proactive coping resources in reactive coping efforts. Theoretical and clinical implications are explored. PMID:21521494

    2017-08-01

    Research on decision-making under stress has mainly involved laboratory-based studies with few contextual descriptions of decision-making under stress in the natural ecology. We examined how police officers prepared for, coped with and made decisions under threat-of-death stress during real events. A delayed retrospective report method was used to elicit skilled police officers' thoughts and feelings during attempts to resolve such events. Reports were analysed to identify experiences of stress and coping, and thought processes underpinning decision-making during the event. Officers experienced a wide range of events, coped with stress predominantly via problem-focused strategies, and adapted their decision-making under stress based on the available context. Future officer training should involve a greater variety of training scenarios than is involved in current training, and expose trainees to the possible variants of each situation to foster better situational representation and, thus, a more reliable and adaptive mental model for use in decision-making. Practitioner Summary: This study concerns decision-making and coping strategies used by skilled police officers during real threat-of-death situations. Officers' decision-making strategies differed according to the complexity of the situation and they coped with the stress of these situations via attempts to resolve the situations (e.g. by planning responses) and, to a lesser extent, via attempts to deal with their emotions.

  8. Molecular Dynamics Simulations with Quantum Mechanics/Molecular Mechanics and Adaptive Neural Networks.

    PubMed

    2018-03-13

    Direct molecular dynamics (MD) simulation with ab initio quantum mechanical and molecular mechanical (QM/MM) methods is very powerful for studying the mechanism of chemical reactions in a complex environment but also very time-consuming. The computational cost of QM/MM calculations during MD simulations can be reduced significantly using semiempirical QM/MM methods with lower accuracy. To achieve higher accuracy at the ab initio QM/MM level, a correction on the existing semiempirical QM/MM model is an attractive idea. Recently, we reported a neural network (NN) method as QM/MM-NN to predict the potential energy difference between semiempirical and ab initio QM/MM approaches. The high-level results can be obtained using neural network based on semiempirical QM/MM MD simulations, but the lack of direct MD samplings at the ab initio QM/MM level is still a deficiency that limits the applications of QM/MM-NN. In the present paper, we developed a dynamic scheme of QM/MM-NN for direct MD simulations on the NN-predicted potential energy surface to approximate ab initio QM/MM MD. Since some configurations excluded from the database for NN training were encountered during simulations, which may cause some difficulties on MD samplings, an adaptive procedure inspired by the selection scheme reported by Behler [ Behler Int. J. Quantum Chem. 2015 , 115 , 1032 ; Behler Angew. Chem., Int. Ed. 2017 , 56 , 12828 ] was employed with some adaptions to update NN and carry out MD iteratively. We further applied the adaptive QM/MM-NN MD method to the free energy calculation and transition path optimization on chemical reactions in water. The results at the ab initio QM/MM level can be well reproduced using this method after 2-4 iteration cycles. The saving in computational cost is about 2 orders of magnitude. It demonstrates that the QM/MM-NN with direct MD simulations has great potentials not only for the calculation of thermodynamic properties but also for the characterization of

    This paper describes the design of a new knee joint mechanism, called the Adaptive Coupling Joint (ACJ). The new mechanism has an adaptive trajectory of the center of rotations (COR) that automatically matches those of the attached biological joint. The detailed design is presented as well as characterization results of the ACJ. Conventional exoskeleton and assistive devices usually consider limb joints as a one to three degrees of freedom (DOFs) joint synthesized by multiple one-DOF hinge joints in a single plane. However, the biological joints are complex and usually rotate with respect to a changing COR. As a result, the mismatch between limb joint motion and mechanical interface motion can lead to forces that cause undesired ligament and muscle length changes and internal mechanical changes. These undesired changes contribute to discomfort, as well as to the slippage and sluggish interaction between humans and devices. It is shown that the ACJ can transmit planetary torques from either active or passive devices to the limbs without altering the normal biological joint motion.

    The ways sexual harassment occurs both online and in face-to-face settings has become more complicated. Sexual harassment that occurs in cyberspace or online sexual harassment adds complexity to the experiences of victims, current research understandings, and the legal dimensions of this phenomenon. Social networking sites (SNS) are a type of social media that offer unique opportunities to users and sometimes the communication that occurs on SNS can cross the line from flirtation into online sexual harassment. Victims of sexual harassment employ communicative strategies such as coping to make sense of their experiences of sexual harassment. The current study qualitatively examined problem-focused, active emotion-focused, and passive emotion-focused coping strategies employed by sexual harassment victims across multiple settings. We conducted 26 in-depth interviews with victims that had experienced sexual harassment across multiple settings (e.g., face-to-face and SNS). The findings present 16 types of coping strategies-five problem-focused, five active emotion-focused, and six passive emotion-focused. The victims used an average of three types of coping strategies during their experiences. Theoretical implications extend research on passive emotion-focused coping strategies by discussing powerlessness and how victims blame other victims. Furthermore, theoretically the findings reveal that coping is a complex, cyclical process and that victims shift among types of coping strategies over the course of their experience. Practical implications are offered for victims and for SNS sites.

  11. Coping with occupational stress: the role of optimism and coping flexibility.

    The current study aimed at measuring whether coping flexibility is a reliable and valid construct in a UK sample and subsequently investigating the association between coping flexibility, optimism, and psychological health - measured by perceived stress and life satisfaction. A UK university undergraduate student sample (N=95) completed an online questionnaire. The study is among the first to examine the validity and reliability of the English version of a scale measuring coping flexibility in a Western population and is also the first to investigate the association between optimism and coping flexibility. The results revealed that the scale had good reliability overall; however, factor analysis revealed no support for the existing two-factor structure of the scale. Coping flexibility and optimism were found to be strongly correlated, and hierarchical regression analyses revealed that the interaction between them predicted a large proportion of the variance in both perceived stress and life satisfaction. In addition, structural equation modeling revealed that optimism completely mediated the relationship between coping flexibility and both perceived stress and life satisfaction. The findings add to the occupational stress literature to further our understanding of how optimism is important in psychological health. Furthermore, given that optimism is a personality trait, and consequently relatively stable, the study also provides preliminary support for the potential of targeting coping flexibility to improve psychological health in Western populations. These findings must be replicated, and further analyses of the English version of the Coping Flexibility Scale are needed.

    2005-05-01

    A survey of parents/caregivers of a child with an autism spectrum disorder (ASD) was conducted to examine the relationship between ASD characteristics, family functioning and coping strategies. Having a child with ASD places considerable stress on the family. Primary caregivers of a child with ASD from a regional and rural area in Victoria, Australia (N = 53) were surveyed concerning their child with ASD, family functioning (adaptability and cohesion), marital satisfaction, self-esteem and coping strategies. Results suggest that these caregivers had healthy self-esteem, although they reported somewhat lower marital happiness, family cohesion and family adaptability than did norm groups. Coping strategies were not significant predictors of these outcome variables. Results highlight the need for support programmes to target family and relationship variables as well as ASD children and their behaviours, in order to sustain the family unit and improve quality of life for parents and caregivers as well as those children.

    2010-01-01

    The Dual Process Model of Coping with Bereavement (DPM; Stroebe & Schut, 1999) is described in this article. The rationale is given as to why this model was deemed necessary and how it was designed to overcome limitations of earlier models of adaptive coping with loss. Although building on earlier theoretical formulations, it contrasts with other models along a number of dimensions which are outlined. In addition to describing the basic parameters of the DPM, theoretical and empirical developments that have taken place since the original publication of the model are summarized. Guidelines for future research are given focusing on principles that should be followed to put the model to stringent empirical test.

  15. Coping Self-Efficacy Mediates the Effects of Negative Cognitions on Posttraumatic Distress

    2008-01-01

    Although cognitive distortions have predicted posttraumatic distress after various types of traumatic events, the mechanisms through which cognitive distortions influence posttraumatic distress remain unclear. We hypothesized that coping self-efficacy, the belief in one’s own ability to manage posttraumatic recovery demands, would operate as a mediator between negative cognitions (about self, about the world, and self-blame beliefs) and posttraumatic distress. In the cross-sectional Study 1, data collected among 66 adult female victims of child sexual abuse indicated that coping self-efficacy mediated the effects of negative cognitions about self and about the world on posttraumatic distress. The same pattern of results was found in a longitudinal Study 2, conducted among 70 survivors of motor vehicle accidents. Coping self-efficacy measured at 1 month after the trauma mediated the effects of 7-day negative cognitions about self and about the world on 3-month posttraumatic distress. In both studies self-blame was not related to posttraumatic distress and the effect of self-blame on posttraumatic distress was not mediated by coping self-efficacy. The results provide insight into a mechanism through which negative cognitions may affect posttraumatic distress and highlight the potential importance of interventions aimed at enhancing coping self-efficacy beliefs.

    The psychosocial adaptation of patients awaiting heart transplantation has not been defined. Forty-one patients (36 men, 5 women; mean age, 48 years) completed standardized questionnaires before transplantation to assess quality of life, physical symptoms, marital/social adjustment, psychiatric morbidity, coping, and compliance to medical regimens. Also, data were obtained from spouses/partners and the transplantation nurse coordinator. Unlike previously reported findings with patients after transplantation, those awaiting transplantation report moderate dissatisfaction with quality of life. Patients report physical symptoms, functional disabilities, sexual dysfunction, and psychological distress. Nonetheless, reported levels of compliance with the medical regimens and of social support were high, and both patients and spouses/partners provided marital adjustment ratings on the Dyadic Adjustment Scale that were comparable to those of well-adjusted, happily married couples. High levels of coping also were recorded. Having a positive attitude and seeking social support were the most common coping strategies, whereas confrontation, acceptance, and escapism were relatively uncommon. In conclusion, patients awaiting heart transplantation, although dissatisfied with quality of life, maintain positive psychological and social adjustment.

    Cancer is often associated with a lot of pain and suffering. These suggest that coping with the symptoms, diagnosis and treatment of cancer is a major life stressor that is capable of influencing patients' quality of life (QoL). The purpose of the study is to assess the relationship between cancer patients' QoL dimensions and coping strategies in the Radiotherapy Department of the University College Hospital Ibadan, Nigeria. Data were collected on clinic days from all available and consenting cancer patients who were receiving treatment at the radiotherapy department. Participants were informed of their right to decline to fill the questionnaires. In this study, 237 cancer patients participated. They had an age range of 15 to 95 years with a mean age of 49.91 years. There was significant inverse relationship between physical well-being with behavioural disengagement, venting, planning and self-blame (p < 0.05); social/family well-being has significant linear relationship with active coping, emotional support, positive reframing, instrumental support, acceptance and religion (p < 0.05); emotional well-being has significant inverse relationship with behavioural disengagement and self-blame (p < 0.05); functional well-being has significant linear relationship with active coping, instrumental support and acceptance (p < 0.05). It is important to assess cancer patients for the kind of coping strategies they are adopting to use in coping with their cancer burden, thereby guiding against lower QoL due to negative coping strategies. Intervention programmes could be developed to help cancer patients adopt more positive and effective coping strategies to improve patients' QoL. Copyright © 2013 John Wiley & Sons, Ltd.

    Our understanding of the coping strategies used by people with visual impairment to manage stress related to visual loss is limited. This study aims to develop a sophisticated coping instrument in the form of an item bank implemented via Computerised adaptive testing (CAT) for hereditary retinal diseases. Items on coping were extracted from qualitative interviews with patients which were supplemented by items from a literature review. A systematic multi-stage process of item refinement was carried out followed by expert panel discussion and cognitive interviews. The final coping item bank had 30 items. Rasch analysis was used to assess the psychometric properties. A CAT simulation was carried out to estimate an average number of items required to gain precise measurement of hereditary retinal disease-related coping. One hundred eighty-nine participants answered the coping item bank (median age = 58 years). The coping scale demonstrated good precision and targeting. The standardised residual loadings for items revealed six items grouped together. Removal of the six items reduced the precision of the main coping scale and worsened the variance explained by the measure. Therefore, the six items were retained within the main scale. Our CAT simulation indicated that, on average, less than 10 items are required to gain a precise measurement of coping. This is the first study to develop a psychometrically robust coping instrument for hereditary retinal diseases. CAT simulation indicated that on an average, only four and nine items were required to gain measurement at moderate and high precision, respectively.

    Insect resistance to plant toxins is widely assumed to have evolved in response to using defended plants as a dietary resource. We tested this hypothesis in the milkweed butterflies (Danaini) which have progressively evolved higher levels of resistance to cardenolide toxins based on amino acid substitutions of their cellular sodium-potassium pump (Na(+)/K(+)-ATPase). Using chemical, physiological and caterpillar growth assays on diverse milkweeds (Asclepias spp.) and isolated cardenolides, we show that resistant Na(+)/K(+)-ATPases are not necessary to cope with dietary cardenolides. By contrast, sequestration of cardenolides in the body (as a defence against predators) is associated with the three levels of Na(+)/K(+)-ATPase resistance. To estimate the potential physiological burden of cardenolide sequestration without Na(+)/K(+)-ATPase adaptations, we applied haemolymph of sequestering species on isolated Na(+)/K(+)-ATPase of sequestering and non-sequestering species. Haemolymph cardenolides dramatically impair non-adapted Na(+)/K(+)-ATPase, but had systematically reduced effects on Na(+)/K(+)-ATPase of sequestering species. Our data indicate that major adaptations to plant toxins may be evolutionarily linked to sequestration, and may not necessarily be a means to eat toxic plants. Na(+)/K(+)-ATPase adaptations thus were a potential mechanism through which predators spurred the coevolutionary arms race between plants and insects. © 2015 The Author(s).

    Insect resistance to plant toxins is widely assumed to have evolved in response to using defended plants as a dietary resource. We tested this hypothesis in the milkweed butterflies (Danaini) which have progressively evolved higher levels of resistance to cardenolide toxins based on amino acid substitutions of their cellular sodium–potassium pump (Na+/K+-ATPase). Using chemical, physiological and caterpillar growth assays on diverse milkweeds (Asclepias spp.) and isolated cardenolides, we show that resistant Na+/K+-ATPases are not necessary to cope with dietary cardenolides. By contrast, sequestration of cardenolides in the body (as a defence against predators) is associated with the three levels of Na+/K+-ATPase resistance.

    Plants can respond to climate change by either migrating, adapting to the new conditions or going extinct. Relict plant species of limited distribution can be especially vulnerable as they are usually composed of small and isolated populations, which may reduce their ability to cope with rapidly changing environmental conditions. The aim of this study was to assess the vulnerability of Cneorum tricoccon L. (Cneoraceae), a Mediterranean relict shrub of limited distribution, to a future drier climate. We evaluated population differentiation in functional traits related to drought tolerance across seven representative populations of the species' range. We measured morphological and physiological traits in both the field and the greenhouse under three water availability levels. Large phenotypic differences among populations were found under field conditions. All populations responded plastically to simulated drought, but they differed in mean trait values as well as in the slope of the phenotypic response. Particularly, dry-edge populations exhibited multiple functional traits that favored drought tolerance, such as more sclerophyllous leaves, strong stomatal control but high photosynthetic rates, which increases water use efficiency (iWUE), and an enhanced ability to accumulate sugars as osmolytes. Although drought decreased RGR in all populations, this reduction was smaller for populations from the dry edge. Our results suggest that dry-edge populations of this relict species are well adapted to drought, which could potentially mitigate the species' extinction risk under drier scenarios. Dry-edge populations not only have a great conservation value but can also change expectations from current species' distribution models.

    Abstract This 10-year study (N=177) examines how people with HIV use spirituality to cope with life's trauma on top of HIV-related stress (e.g., facing death, stigma, poverty, limited healthcare) usual events. Spirituality, defined as a connection to a higher presence, is independent from religion (institutionalized spirituality). As a dynamic adaptive process, coping requires longitudinal studying. Qualitative content-analysis of interviews/essays yielded a coding of specific aspects and a longitudinal rating of overall spiritual coping. Most participants were rated as spiritual, using spiritual practices, about half experienced comfort, empowerment, growth/transformation, gratitude, less than one-third meaning, community, and positive reframing. Up to one-fifth perceived spiritual conflict, struggle, or anger, triggering post-traumatic stress, which sometimes converted into positive growth/transformation later. Over time, 65% used spiritual coping positively, 7% negatively, and 28% had no significant use. Spirituality was mainly beneficial for women, heterosexuals, and African Americans (p<0.05). Results suggest that spirituality is a major source of positive and occasionally negative coping (e.g., viewing HIV as sin). We discuss how clinicians can recognize and prevent when spirituality is creating distress and barriers to HIV treatment, adding a literature review on ways of effective spiritual assessment. Spirituality may be a beneficial component of coping with trauma, considering socio-cultural contexts. PMID:24601735

    It has become more and more evident that many difficulties encountered in the course of aircraft flutter analyses can be traced to strong localized nonlinearities in the control mechanisms. To cope with these problems, more reliable mathematical models paying special attention to control system nonlinearities were established by means of modified ground vibration test procedures in combination with suitably adapted modal synthesis approaches. Three different concepts are presented.

    The ability to perform under pressure is necessary to achieve goals in various domains of life. We conducted a systematic review to synthesise findings from applied studies that focus on interventions developed to enhance an individual’s ability to cope under performance pressure. Following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines, a comprehensive search of five electronic databases was conducted. This yielded 66,618 records, of which 23 peer review papers met inclusion criteria of containing an intervention that targeted coping skills for performing under pressure. Using the Standard Quality Assessment for evaluation of primary research papers (Kmet et al., 2004) to assess quality, included studies performed well on reporting research objectives, research design, and statistical procedures. Sixteen studies showed poor quality in controlling for potentially confounding factors and small sample sizes. A narrative aggregate synthesis identified intervention studies that provided an educational focus (n = 9), consultancy sessions (n = 6), simulation training (n = 5) and emotion regulation strategies (n = 3). Findings highlight a need to; 1) establish a contextualized pressure task which will generate high levels of ecological validity for participants. Having established a suitable pressure task, 2) research should assess the effects of pressure by evaluating conscious and nonconscious effects and associated coping mechanisms, which should inform the subsequent development of interventions, and 3) assess interventions to enhance understanding of the ways in which they improve coping with pressure, or may fail, and the mechanisms which may explain these outcomes. Key points Simulation studies that exposed individuals to ‘pressure’ settings produced the most consistent improvements to performance, in comparison to a control group. This systematic review highlights limitations with the design, execution, and

    Caregivers face challenges to adapt while handling individual with learning disabilities (LD). The Family Crisis Oriented Personal Evaluation Scale (F-COPES) is a widely used instrument to measure coping strategies among caregivers. The current study performed cross cultural translation of F-COPES in Malay language. This study aims to examine the reliability by testing internal consistency of Malay version of F-COPES which is developed through back to back translation method from original English version. The Malay version of F-COPES was administered among 30 caregivers. The reliability of F-COPES in Malay version is good with Cronbach's alpha coefficient value of 0.79. The internal consistency on sub domains of F-COPES such as reframing, acquiring social support and seeking spiritual support also acceptable with Cronbach's alpha values 0.67, 0.74, and 0.80, respectively. The Malay version of F-COPES is a reliable tool to evaluate the coping strategies adopted by the caregivers of individual with LD.

    1999-01-01

    We postulate that centripetal acceleration induced by centrifugation can be used as an inflight sensorimotor countermeasure to retain and/or promote appropriate crewmember responses to sustained changes in gravito-inertial force conditions. Active voluntary motion is required to promote vestibular system conditioning, and both visual and graviceptor sensory feedback are critical for evaluating internal representations of spatial orientation. The goal of our investigation is to use centrifugation to develop an analog to the conflicting visual/gravito-inertial force environment experienced during space flight, and to use voluntary head movements during centrifugation to study mechanisms of adaptation to altered gravity environments. We address the following two hypotheses: (1) Discordant canal-otolith feedback during head movements in a hypergravity tilted environment will cause a reorganization of the spatial processing required for multisensory integration and motor control, resulting in decreased postural stability upon return to normal gravity environment. (2) Adaptation to this "gravito-inertial tilt distortion" will result in a negative after-effect, and readaptation will be expressed by return of postural stability to baseline conditions. During the third year of our grant we concentrated on examining changes in balance control following 90-180 min of centrifugation at 1.4 9. We also began a control study in which we exposed subjects to 90 min of sustained roll tilt in a static (non-rotating) chair. This allowed us to examine adaptation to roll tilt without the hypergravity induced by centrifugation. To these ends, we addressed the question: Is gravity an internal calibration reference for postural control? The remainder of this report is limited to presenting preliminary findings from this study.

    Cognitive flexibility is essential to cope with changing task demands and often it is necessary to adapt to combined changes in a coordinated manner. The present fMRI study examined how the brain implements such multi-level adaptation processes. Specifically, on a "local," hierarchically lower level, switching between two tasks was required across trials while the rules of each task remained unchanged for blocks of trials. On a "global" level regarding blocks of twelve trials, the task rules could reverse or remain the same. The current task was cued at the start of each trial while the current task rules were instructed before the start of a new block. We found that partly overlapping and partly segregated neural networks play different roles when coping with the combination of global rule reversal and local task switching. The fronto-parietal control network (FPN) supported the encoding of reversed rules at the time of explicit rule instruction. The same regions subsequently supported local task switching processes during actual implementation trials, irrespective of rule reversal condition. By contrast, a cortico-striatal network (CSN) including supplementary motor area and putamen was increasingly engaged across implementation trials and more so for rule reversal than for nonreversal blocks, irrespective of task switching condition. Together, these findings suggest that the brain accomplishes the coordinated adaptation to multi-level demand changes by distributing processing resources either across time (FPN for reversed rule encoding and later for task switching) or across regions (CSN for reversed rule implementation and FPN for concurrent task switching). © 2017 Wiley Periodicals, Inc.

    Justice-involved women report high rates of victimization across their life span, and these experiences contribute to their involvement in the criminal justice (CJ) system. Within this population, research has identified an overlap among victimization and substance use, a high-risk coping mechanism. Furthermore, research indicates attachment style is related to coping and high-risk behaviors. Research is needed to understand the relationship among these mechanisms as they relate to intimate partner violence (IPV). To address this gap, this study investigated the relationship between attachment, coping, childhood victimization, substance use, and IPV among 406 victimized women on probation/parole. Results of 6 multivariate regression analyses were statistically significant, accounting for 8%-13% of the variance in IPV. Particularly, childhood sexual victimization and negative coping were significant in all analyses. Findings provide practitioners, administrators, and policymakers information about the specific needs of justice-involved women.

    2011-09-01

    Current, highly active classes of adaptive materials have been considered for use in many different aerospace applications. From adaptive flight control surfaces to wing surfaces, shape-memory alloy (SMA), piezoelectric and electrorheological fluids are making their way into wings, stabilizers and rotor blades. Despite the benefits which can be seen in many classes of aircraft, some profound challenges are ever present, including low power and energy density, high power consumption, high development and installation costs and outright programmatic blockages due to a lack of a materials certification database on FAR 23/25 and 27/29 certified aircraft. Three years ago, a class of adaptive structure was developed to skirt these daunting challenges. This pressure-adaptive honeycomb (PAH) is capable of extremely high performance and is FAA/EASA certifiable because it employs well characterized materials arranged in ways that lend a high level of adaptivity to the structure. This study is centered on laying out the mechanics, analytical models and experimental test data describing this new form of adaptive material. A directionally biased PAH system using an external (spring) force acting on the PAH bending structure was examined. The paper discusses the mechanics of pressure adaptive honeycomb and describes a simple reduced order model that can be used to simplify the geometric model in a finite element environment. The model assumes that a variable stiffness honeycomb results in an overall deformation of the honeycomb. Strains in excess of 50% can be generated through this mechanism without encountering local material (yield) limits. It was also shown that the energy density of pressure-adaptive honeycomb is akin to that of shape-memory alloy, while exhibiting strains that are an order of magnitude greater with an energy efficiency close to 100%. Excellent correlation between theory and experiment is demonstrated in a number of tests. A proof-of-concept wing section

    Purpose To describe daily stressors affecting and coping strategies employed by individuals with whiplash-associated disorders (WAD) immediately to one month (acute) and three to four months (sub-acute) after injury events using a daily coping assessment. Levels of pain, anxiety, depressed mood and activity are also compared between phases. Method A descriptive prospective design with a content analysis approach was used. Participants completed daily coping assessments for one week during both acute and sub-acute phases. Main measure was whiplash-associated disorders-daily coping assessment (WAD-DCA). Results Nine participants used words describing recovery in the sub-acute phase; 31 described stressful events during both phases. Most frequently reported stressors were related to "symptoms", "emotions" and "occupations/studies". These were equally reported during both phases. Cognitive coping strategies were employed more often during the sub-acute phase (p = 0.008). The only behavioral strategy that increased in prevalence over time was the "relaxed" strategy (p = 0.001). Anxiety levels declined over time (p = 0.022). Conclusion The reported stressors were largely uniform across both acute and sub-acute phases; however, the use of cognitive coping strategies increased over time. The WAD-DCA captures individual stressors and coping strategies employed during a vulnerable phase of rehabilitation and can thus provide information that is useful to clinical practice. Implications for rehabilitation The WAD-DCA provides valuable information for clinical practice when employed during early phases of whiplash-associated disorder development. Reported stressors during the acute and sub-acute phases are essentially the same, whereas cognitive coping strategies grow in prevalence over time. Tailored treatments in early phases of whip-lash associated disorders may benefit from strategies aimed at matching patient-specific stressors with contextually adapted coping

We examined coping behaviors related to suicidal ideation and gender differences in adolescents using the data from the 2010 Korea Youth Risk Behavior Survey (ages 12-19 years; N = 73,238). Logistic regression analysis was used to evaluate associations between suicidal ideation and specific coping behaviors while controlling for potentially confounding variables. In both male and female groups, the coping behavior "drinking alcoholic beverages" and "smoking cigarettes" were positively associated with suicidal ideation. "Watching TV," "playing online/mobile games," and "sleeping" were negatively associated with suicidal ideation in both groups. In males, "engaging in sports" was negatively related to suicidal ideation. In females, "venting by talking to others" and "eating" were negatively related to suicidal ideation. The results indicate that there are gender differences in the effects of coping behaviors on adolescent suicidal ideation, and that developing adaptive coping strategies may function to reduce suicidality. Future studies are needed to examine whether improving coping skills can reduce suicidal ideation in a gender-specific manner.

    We recently introduced a series of stimuli-responsive, mechanically-adaptive polymer nanocomposites. Here, we report the first application of these bio-inspired materials as substrates for intracortical microelectrodes. Our hypothesis is that the ideal electrode should be initially stiff to facilitate minimal trauma during insertion into the cortex, yet becomes mechanically compliant to match the stiffness of the brain tissue and minimize forces exerted on the tissue, attenuating inflammation. Microprobes created from mechanically reinforced nanocomposites demonstrated a significant advantage compared to model microprobes composed of neat polymer only. The nanocomposite microprobes exhibit a higher storage modulus (E’ = ~5 GPa) than the neat polymer microprobes (E’ = ~2 GPa) and could sustain higher loads (~17 mN), facilitating penetration through the pia mater and insertion into the cerebral cortex of a rat. In contrast, the neat polymer microprobes mechanically failed under lower loads (~7 mN) before they were capable of inserting into cortical tissue. Further, we demonstrated the material’s ability to morph while in the rat cortex to more closely match the mechanical properties of the cortical tissue. Nanocomposite microprobes that were implanted into the rat cortex for up to 8 weeks demonstrated increased cell density at the microelectrode-tissue interface and a lack of tissue necrosis or excessive gliosis. This body of work introduces our nanocomposite-based microprobes as adaptive substrates for intracortical microelectrodes and potentially other biomedical applications. PMID:21654037

    Adaptation of agents through learning or evolution is an important component of the resilience of Complex Adaptive Systems (CAS). Without adaptation, the flexibility of such systems to cope with outside pressures would be much lower. To study the capabilities of CAS to adapt, social simulations with agent-based models (ABMs) provide a helpful tool. However, the value of ABMs for studying adaptation depends on the availability of methodologies for sensitivity analysis that can quantify resilience and adaptation in ABMs. In this paper we propose a sensitivity analysis methodology that is based on comparing time-dependent probability density functions of output of ABMs with and without agent adaptation. The differences between the probability density functions are quantified by the so-called earth-mover’s distance. We use this sensitivity analysis methodology to quantify the probability of occurrence of critical transitions and other long-term effects of agent adaptation. To test the potential of this new approach, it is used to analyse the resilience of an ABM of adaptive agents competing for a common-pool resource. Adaptation is shown to contribute positively to the resilience of this ABM. If adaptation proceeds sufficiently fast, it may delay or avert the collapse of this system. PMID:28196372

    This study seeks to validate the Spanish version of the Dyadic Coping Inventory (DCI) in a Latino population with data from 113 heterosexual couples. Results for both partners confirm the factorial structure for the Spanish version (Subscales: Stress Communication, Emotion- and Problem-Focused Supportive, Delegated, and Negative Dyadic Coping, Emotion- and Problem-Focused Common Dyadic Coping, and Evaluation of Dyadic Coping; Aggregated Scales: Dyadic Coping by Oneself and by Partner) and support the discriminant validity of its subscales and the concurrent, and criterion validity of the subscales and aggregated scales. These results do not only indicate that the Spanish version of the DCI can be used reliably as a measure of coping in Spanish-speaking Latino couples, but they also suggest that this group relies on dyadic coping frequently and that this type of coping is associated with positive relationship functioning and individual coping. Limitations and implications are discussed.

  1. Reactance and Coping Responses to Tobacco Counter-Advertisements.

    Tobacco prevention messages generally take one of three tactics: They can be educational, attack the tobacco industry, or attack particular brands. Being a smoker and smoking a particular brand may form an essential part of a person's self-identity. As such, reactance theory suggests that attack messages can unintentionally attack smokers' self-image. A 2 × 2 × 2 × 2 experiment using six different messages and 260 respondents tested whether smokers have different reactions to tobacco counter-advertisements than nonsmokers. It also examined whether attacking a smoker's brand leads to greater reactance and other maladaptive responses compared to attacking other brands. Consistent with predictions, smokers reported more maladaptive coping responses and fewer adaptive coping responses to tobacco counter-ads than nonsmokers. The study also reveals differences attributable to brand identification. These findings suggest that interventions should consider different counter-advertising tactics for smokers and nonsmokers. Similar admonitions may apply to counter-advertising strategies on other health issues.

    This prospective study investigated whether within-individual relations between depression vulnerability factors (childhood trauma, dysfunctional attitudes, maladaptive coping) and depressive symptom trajectories varied as a function of the number of prior major depressive episodes (MDEs) experienced in their lifetime. Participants were 68 young adults who varied with regard to their history of depression; 32 were remitted depressed and 36 were never depressed. Depressive symptoms and disorders were assessed using semi-structured psychiatric interviews conducted twice over a 6-month period; interviews yielded weekly ratings of depressive symptoms during the follow-up interval. Childhood trauma, dysfunctional attitudes and coping were assessed with self-report measures. Data analyses were conducted using time-lagged multilevel models. Individuals with more previous MDEs who reported greater childhood trauma exposure, more dysfunctional attitudes, or greater use of maladaptive coping strategies experienced more rapid increases in depressive symptoms during the follow-up period. A significant interaction of coping, number of previous MDEs, and time was found indicating that among individuals with less adaptive coping (i.e., lower primary or lower secondary control coping scores), depressive symptoms rating (DSR) increased significantly in relation to number of prior depressive episodes; no change in DSR was observed for never-depressed individuals. Among individuals with higher primary control coping scores, significant increases in DSR scores were observed for individuals with ≥3 prior MDEs only. Findings highlight the need for treatment and prevention programmes that target stress reactivity and coping strategies early in the course of depression. © 2013 The British Psychological Society.

    Understanding how populations at particular risk for posttraumatic stress disorder (PTSD) and its deleterious outcomes cope with individual PTSD symptoms is critical to developing interventions that promote resilience, support recovery, and ultimately empower traumatized populations. Therefore, the purpose of this study was to identify specific strategies women use to cope with individual PTSD symptoms among a population at particular risk for experiencing trauma and its negative sequelae-African American victims of intimate partner violence (IPV) who use substances. This 30-day study included 107 African American women who reported experiencing current IPV and using a substance. During their follow-up interviews, women participated in a structured interview to retrospectively report on the strategies they typically used to cope with various PTSD symptoms during the 30-day period. Results of content analysis revealed that women used 19 different strategies to cope with symptoms (e.g., social support, substance use, electronic media, religious or spiritual coping), which varied as a function of the PTSD symptom experienced. Aggregating symptoms to the cluster level obscured the variability in strategies used to cope with individual symptoms. Findings are discussed in the context of the larger literature on coping and PTSD, specifically regarding (a) coping strategies that may be adaptive or maladaptive and (b) directions for future research that attend to experiences of individual PTSD symptoms.

    To examine a self-regulation and coping model for interstitial cystitis/bladder pain syndrome (IC/BPS) that may help us understand the pain experience of patients with chronic IC/BPS. The model tested illness perceptions, illness-focused coping, emotional regulation, mental health and disability in a stepwise method using factor analysis and structural equation modelling. Step 1, explored the underlying constructs. Step 2, confirmed the measurement models to determine the structure/composition of the main constructs. Step 3, evaluated the model fit and specified pathways in the proposed IC/BPS self-regulation model. In all, 217 female patients with urologist diagnosed IC/BPS were recruited and diagnosed across tertiary care centres in North America. The data were collected through self-report questionnaires. An IC/BPS self-regulation model was supported. Physical disability was worsened by patient's negative perception of their illness, attempts to cope using illness-focused coping and poorer emotional regulation. Mental health was supported by perceptions that individuals could do something about their illness, using wellness-focused behavioural strategies and adaptive emotion regulation. The results clarify the complex and unique process of self-regulation in women with IC/BPS, implicating cognitive and coping targets, and highlighting emotional regulation. This knowledge should help clinicians understand and manage these patients' distress and disability. © 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.

    Humans tend to avoid mental effort. Previous studies have demonstrated this tendency using various demand-selection tasks; participants generally avoid options associated with higher cognitive demand. However, it remains unclear whether humans avoid mental effort adaptively in uncertain and non-stationary environments, and if so, what neural mechanisms underlie this learned avoidance and whether they remain the same irrespective of cognitive-demand types. We addressed these issues by developing novel demand-selection tasks where associations between choice options and cognitive-demand levels change over time, with two variations using mental arithmetic and spatial reasoning problems (29:4 and 18:2 males:females). Most participants showed avoidance, and their choices depended on the demand experienced on multiple preceding trials. We assumed that participants updated the expected cost of mental effort through experience, and fitted their choices by reinforcement learning models, comparing several possibilities. Model-based fMRI analyses revealed that activity in the dorsomedial and lateral frontal cortices was positively correlated with the trial-by-trial expected cost for the chosen option commonly across the different types of cognitive demand, and also revealed a trend of negative correlation in the ventromedial prefrontal cortex. We further identified correlates of cost-prediction-error at time of problem-presentation or answering the problem, the latter of which partially overlapped with or were proximal to the correlates of expected cost at time of choice-cue in the dorsomedial frontal cortex. These results suggest that humans adaptively learn to avoid mental effort, having neural mechanisms to represent expected cost and cost-prediction-error, and the same mechanisms operate for various types of cognitive demand. SIGNIFICANCE STATEMENT In daily life, humans encounter various cognitive demands, and tend to avoid high-demand options. However, it remains unclear

  7. The relationship between cognitive dysfunction and coping abilities in schizophrenia.

    Cognitive dysfunction is a core feature of schizophrenia [Psychiatr. Clin. North Am., 16 (1993) 295; Psychopharmacology: The fourth generation of progress, Raven Press, New York (1995) 1171; Clinical Neuropsychology, Oxford University Press, New York (1993) 449] and is related to psychosocial functioning in this population [Am. J. Psychiatry, 153 (1996) 321]. It is unclear whether cognitive dysfunction is related to specific areas of functioning in schizophrenia, such as coping abilities. Individuals with schizophrenia have deficient coping skills, which may contribute to their difficulties dealing with stressors [Am. J. Orthopsychiatry, 62 (1992) 117; J. Abnorm. Psychol., 82 (1986) 189]. The current study examined the relationship between coping abilities and cognitive dysfunction in a community sample of individuals with schizophrenia. It was hypothesized that executive dysfunction and mnemonic impairments would be positively related to deficiencies in active coping efforts involving problem solving and self-initiation (e.g. advocating for oneself and others with mental illness and becoming involved in meaningful activities, such as work), independent of the contributions of the general intellectual deficits associated with the disorder and psychiatric symptoms. The results indicated that both executive dysfunction and mnemonic impairments were related to decreased usage of active coping mechanisms after controlling for general intellectual deficits. Further, recognition memory made independent contributions to the prediction of coping involving action and help seeking after controlling for the effects of negative symptoms. These findings suggest that individuals with schizophrenia may be less flexible in their use of coping strategies, which may in turn contribute to their difficulties in coping with mental illness and its consequences.

    This qualitative study describes nurses' reports on the role played by religious faith in the care of patients with terminal cancer. Using Gadamer's philosophical hermeneutics and C. Roy's adaptation model as a base, in-depth interviews were carried out with 23 nurses who had cared for patients with terminal cancer for at least 6 months. Three main themes emerged when a Gadamerian-based hermeneutic research method was applied: faith facilitates the coping process in cases of terminal cancer, faith hinders the coping process in cases of terminal cancer and terminal illness impacts faith. The lack of univocal results indicates that the role of faith in coping with death is essentially practical, individualised and changeable. The nurse-patient relationship can help to determine the spiritual needs of cancer patients at the end of life. This source of knowledge held by the nurse, together with the rest of the multidisciplinary team, can help to improve end-of-life care. © 2013 John Wiley & Sons Ltd.

    Purpose The purpose of this study was to describe how coping styles among African Americans with type 2 diabetes relate to diabetes appraisals, self-care behaviors, and health-related quality of life or well-being. Methods This cross-sectional analysis of baseline measures from 185 African Americans with type 2 diabetes enrolled in a church-based randomized controlled trial uses the theoretical framework of the transactional model of stress and coping to describe bivariate and multivariate associations among coping styles, psychosocial factors, self-care behaviors, and well-being, as measured by validated questionnaires. Results Among participants who were on average 59 years of age with 9 years of diagnosed diabetes, passive and emotive styles of coping were used most frequently, with older and less educated participants using more often passive forms of coping. Emotive styles of coping were significantly associated with greater perceived stress, problem areas in diabetes, and negative appraisals of diabetes control. Both passive and active styles of coping were associated with better diabetes self-efficacy and competence in bivariate analysis. In multivariate analysis, significant proportions of the variance in dietary behaviors and mental well-being outcomes (general and diabetes specific) were explained, with coping styles among the independent predictors. A positive role for church involvement in the psychological adaptation to living with diabetes was also observed. Conclusions In this sample of older African Americans with diabetes, coping styles were important factors in diabetes appraisals, self-care behaviors, and psychological outcomes. These findings suggest potential benefits in emphasizing cognitive and behavioral strategies to promote healthy coping outcomes in persons living with diabetes. PMID:18535323

    This is a novel investigation of whether, and how, a single close supportive friendship may facilitate psychological resilience in socio-economically vulnerable British adolescents. A total of 409 adolescents (160 boys, 245 girls, four unknown), aged between 11 and 19 years, completed self-report measures of close friendship quality, psychological resilience, social support, and other resources. Findings revealed a significant positive association between perceived friendship quality and resilience. This relationship was facilitated through inter-related mechanisms of developing a constructive coping style (comprised of support-seeking and active coping), effort, a supportive friendship network, and reduced disengaged and externalising coping. While protective processes were encouragingly significantly present across genders, boys were more vulnerable to the deleterious effects of disengaged and externalizing coping than girls. We suggest that individual close friendships are an important potential protective mechanism accessible to most adolescents. We discuss implications of the resulting Adolescent Friendship and Resilience Model for resilience theories and integration into practice. © 2015 The British Psychological Society.

    To determine the visual adaptation and retinal eccentricity profiles for red flickering and static test stimuli and report a clinical implementation of these stimuli in visual perimetry. The adaptation profile for red-on-white perimetry stimuli was measured using a threshold vs. intensity (TvI) paradigm at 0 degree and 12 degrees eccentricity and by comparing the eccentricity-related sensitivity change for red and white, static, and flickering targets in young normal trichromats (n = 5) and a group of dichromats (n = 5). A group of older normal control observers (n = 30) were tested and retinal disease was evaluated in persons having age-related maculopathy (n = 35) and diabetes (n = 12). Adaptation and eccentricity profiles indicate red static and flickering targets are detected by two mechanisms in the paramacular region, and a single mechanism for >5 degrees eccentricity. The group data for the older normal observers has a high level of inter-observer variability with a generalized reduction in sensitivity across the entire visual field. Group data for the participants with age-related maculopathy show reduced sensitivities that were pronounced in the central retina. The group data for the diabetic observers showed sensitivities that were reduced at all eccentricities. The disease-related sensitivity decline was more apparent with red than white stimuli. The adaptation profile and change in sensitivity with retinal eccentricity for the red-on-white perimetric stimuli are consistent with two detection processes. In the macula, the putative detection mechanism is color-opponent with static targets and non-opponent with flickering targets. At peripheral field locations, the putative detection mechanism is non-opponent for both static and flicker targets. The long-wavelength stimuli are less affected by the preretinal absorption common to aging. Red-on-white static and flicker perimetry may be useful for monitoring retinal disease, revealing greater abnormalities

    In social groups, individuals are often confronted with evaluations of their behaviour by other group members and are motivated to adapt their own behaviour accordingly. In two studies we examine emotional responses towards, and perceived coping abilities with, morality vs. competence evaluations individuals receive from other in-group members. In Study 1, we show that evaluations of one's immoral behaviour primarily induce guilt, whereas evaluations of incompetent behaviour raise anger. In Study 2, we elaborate on the psychological process associated with these emotional responses, and demonstrate that evaluations of immorality, compared to incompetence, diminish group members' perceived coping abilities, which in turn intensifies feelings of guilt. However, when anticipating an opportunity to restore one's self-image as a moral group member, perceived coping abilities are increased and the experience of guilt is alleviated. Together these studies demonstrate how group members can overcome their moral misery when restoring their self-image.

    When parents are diagnosed with cancer, children experience significant distress. There is little information regarding the nature of this distress and how children cope, particularly when a parent is diagnosed with advanced cancer. This study aimed to explore how children cope, and to identify areas where there may be barriers to children accessing support to enable them to cope. Semi-structured interviews were conducted with ill parents with advanced cancer and well parents and/or any children above the age of 7. Interviews were recorded and transcribed fully, and analysed using a constructionist grounded theory approach. Twenty-eight family participants were interviewed. Four major themes emerged from the data including response to diagnosis, mechanisms of coping, life changes, and positive aspects. Children described being distressed by their parents diagnosis and having concerns related to their parents and their own health. Distraction and maintaining normality were described as the dominant strategies of coping for children, and increased responsibilities and decreased social activity were considered to be the most noticeable of life changes. Parents did not recognise the impact on children to the same degree as described by children and focused on limiting the impact by maintaining normality. Positive aspects described by children and parents included strengthening of relationships and learning to value family members and the important things in life. Open communication within the family may lead to more effective coping and a positive experience for children whose parents have been diagnosed with advanced cancer.

    Marginal and internal adaptation is critical for the success of indirect restorations. New imaging systems make it possible to evaluate these parameters with precision and non-destructively. This study evaluated the marginal and internal adaptation of zirconia copings fabricated with two different systems using both silicone replica and microcomputed tomography (micro-CT) assessment methods. A metal master model, representing a preparation for an all-ceramic full crown, was digitally scanned and polycrystalline zirconia copings were fabricated with either Ceramill Zi (Amann-Girrbach) or inCoris Zi (Dentslpy-Sirona), n=10. For each coping, marginal and internal gaps were evaluated by silicone replica and micro-CT assessment methods. Four assessment points of each replica cross-section and micro-CT image were evaluated using imaging software: marginal gap (MG), axial wall (AW), axio-occlusal angle (AO) and mid-occlusal wall (MO). Data were statistically analyzed by factorial ANOVA and Tukey test (a=0.05). There was no statistically significant difference between the methods for MG and AW. For AO, there were significant differences between methods for Amann copings, while for Dentsply-Sirona copings similar values were observed. For MO, both methods presented statistically significant differences. A positive correlation was observed determined by the two assessment methods for MG values. In conclusion, the assessment method influenced the evaluation of marginal and internal adaptation of zirconia copings. Micro-CT showed lower marginal and internal gap values when compared to the silicone replica technique, although the difference was not always statistically significant. Marginal gap and axial wall assessment points showed the lower gap values, regardless of ceramic system and assessment method used.

    By virtue of their anatomical location between muscles and bones, tendons make it possible to transform contractile force to joint rotation and locomotion. However, tendons do not behave as rigid links, but exhibit viscoelastic tensile properties, thereby affecting the length and contractile force in the in-series muscle, but also storing and releasing elastic stain energy as some tendons are stretched and recoiled in a cyclic manner during locomotion. In the late 90s, advancements were made in the application of ultrasound scanning that allowed quantifying the tensile deformability and mechanical properties of human tendons in vivo. Since then, the main principles of the ultrasound-based method have been applied by numerous research groups throughout the world and showed that tendons increase their tensile stiffness in response to exercise training and chronic mechanical loading, in general, by increasing their size and improving their intrinsic material. It is often assumed that these changes occur homogenously, in the entire body of the tendon, but recent findings indicate that the adaptations may in fact take place in some but not all tendon regions. The present review focuses on these regional adaptability features and highlights two paradigms where they are particularly evident: (a) Chronic mechanical loading in healthy tendons, and (b) tendinopathy. In the former loading paradigm, local tendon adaptations indicate that certain regions may “see,” and therefore adapt to, increased levels of stress. In the latter paradigm, local pathological features indicate that certain tendon regions may be “stress-shielded” and degenerate over time. Eccentric exercise protocols have successfully been used in the management of tendinopathy, without much sound understanding of the mechanisms underpinning their effectiveness. For insertional tendinopathy, in particular, it is possible that the effectiveness of a loading/rehabilitation protocol depends on the topography

    Objective To examine mediators of the association between childhood attention-deficit/hyperactivity disorder (ADHD) and adolescent cigarette use. Method Participants were 142 adolescents diagnosed with ADHD in childhood and 100 adolescents without ADHD. Results Among probands, cigarette smoking was more frequent, adaptive coping skills (behavioral and cognitive) were fewer, and parental support was lower. Coping and support partially mediated the ADHD association with smoking. Persistence of ADHD and adolescent conduct disorder were also important. Conclusions Vulnerability to smoking among probands may be partly due to fewer problem-solving resources. Coping skill deficits and parent–child communication may be important treatment targets for smoking prevention. PMID:15863431

    Digital health is an increasingly popular tool for patient engagement, having shown great success in arenas such as medication adherence, management of chronic conditions, and patient safety. Given the growth of chronic pain diagnoses, it is imperative to find new technologies to improve care for this particular population. Little research has catalogued the use of digital health in the chronic pain patient population. This manuscript's objective was to describe current patterns of digital health usage among chronic pain patients and how digital health use correlates with health care utilization and health outcomes. A cross-sectional survey was administered to patients with a self-identified chronic pain diagnosis participating in 'Patients Like Me' ® (PLM), an organization that directly collects data from patients experiencing chronic health conditions, with emphasis on patient-centered outcomes and experiences interacting with the health care system. Validated measures of healthcare utilization, chronic pain management, and digital health use were adapted for the survey. Digital health was defined as the use of online sites, social media, and mobile phone applications before, during, or after healthcare utilization. Descriptive statistics, chi square tests, logistic regression, and linear regression were used as appropriate for analysis. Among 565 respondents (mean age 51.3, 87.2% female, 45.7% publicly insured), most participants (89.5%) reported some digital health use. Females and users below the age of 50 were more likely to use multiple forms of digital health. Healthcare utilization, education level, and race/ethnicity did not correlate with digital health use. Patients using more types of digital health reported significantly higher levels of pain coping skills in the realms of social support, relaxation, and exercise. Digital health use is common among a wide range of patients with chronic pain diagnoses. The use of multiple forms of digital health is

    Although coping has been shown to influence physical health in younger populations, whether coping affects health in older adults appears to depend upon how coping and health are conceptualized. This article reviews recent literature on coping and health in older adults in three areas. First, we discuss coping's distinct relevance to health in older adults. Second, we describe ways in which coping may differ between older and younger populations. Third, we detail recent and notable findings of coping's specific effects on biomedical health and health in general. The recent literature suggests that coping may be a developmental and multifaceted process. Positive coping strategies may have positive and even protective effects on health, whereas negative strategies may have negative effects.

    Religious coping is known as a main resource influencing how individuals cope with the complications and stressors of chronic disease. The aim of this study was to assess the relationship between religious coping and quality of life among hemodialysis patients. This cross-sectional study was conducted in Qom, Iran, from June 2012 to July 2013. Ninety-five end-stage renal disease (ESRD) patients undergoing hemodialysis were selected via the convenience sampling method. Data were collected via a questionnaire comprising items on sociodemographic information, quality of life, the anxiety and depression scale, and religious coping. Following this, the data were analyzed using descriptive statistics and logistic regression analysis. The mean age of patients was 50.4 (standard deviation [SD] = 15.7) years, and most were male (61%). The mean score for positive religious coping was 23.38 (SD = 4.17), while that for negative religious coping was 11.46 (SD = 4.34). It was found that 53.6% of patients had higher than the mean score of positive religious coping, while those with negative religious coping made up 37.9%. Negative religious coping was associated with worse quality of life, including physical functioning (odds ratio [OR] = 0.72; P = 0.009), role physical (OR = 0.79; P = 0.04), vitality (OR = 0.62; P = 0.005), social functioning (OR = 0.69; P = 0.007), and mental health (OR = 0.58; P = 0.01) after controlling for sociodemographic, clinical, and anxiety and depression variables. The results indicated that patients with negative religious coping abilities were at risk of a suboptimal quality of life. Incorporating religious support in the care of hemodialysis patients may be helpful in improving quality of life in this patient population. Further longitudinal studies are needed to determine whether these associations are causal and the direction of effect.

    Millions of children incur potentially traumatic physical injuries every year. Most children recover well from their injury but many go on to develop persistent traumatic stress reactions. This study aimed to describe children's coping and coping assistance (i.e., the ways in which parents and peers help children cope) strategies and to explore the association between coping and acute stress reactions following an injury. Children (N = 243) rated their acute traumatic stress reactions within one month of injury and reported on coping and coping assistance six months later. Parents completed a measure of coping assistance at the six-month assessment. Children used an average of five to six coping strategies (out of 10), with wishful thinking, social support, and distraction endorsed most frequently. Child coping was associated with parent and peer coping assistance strategies. Significant acute stress reactions were related to subsequent child use of coping strategies (distraction, social withdrawal, problem-solving, blaming others) and to child report of parent use of distraction (as a coping assistance strategy). Findings suggest that children's acute stress reactions may influence their selection of coping and coping assistance strategies. To best inform interventions, research is needed to examine change in coping behaviors and coping assistance over time, including potential bidirectional relationships between trauma reactions and coping.

    The prevalence of negative life events (NLE) and daily hassles, and their direct and moderated associations with depression, were examined among HIV-infected adolescents. Specifically, we examined whether the negative association with depression of NLE, daily hassles, and/or passive coping were moderated by social support or active coping strategies. Demographic characteristics, depression, coping, social support, NLE, and daily hassles were collected at baseline as part of the Adolescent Impact intervention via face-to-face and computer-assisted interviews. Of 166 HIV-infected adolescents, 53% were female, 72.9% black, 59.6% with perinatally acquired HIV (PIY), the most commonly reported NLE were death in family (81%), violence exposure (68%), school relocation (67%), and hospitalization (61%); and for daily hassles "not having enough money (65%)". Behaviorally infected youth (BIY--acquired HIV later in life) were significantly more likely to experience extensive (14-21) lifetime NLE (38.8% vs. 16.3%, p < .012) than PIY. In multiple stepwise regression analysis, the model accounting for the greatest variability in depression scores (32%) included (in order of entry): daily hassles, low social support, behaviorally acquired HIV, minority sexual orientation, and passive coping. A significant passive coping-by-social support interaction revealed that the association between passive coping and depression was exacerbated when social support was low. Social support moderated the effect of NLE, such that NLE were associated with greater depression when social support was low, although the effect did not remain statistically significant when main effects of other variables were accounted for. Daily hassles, poor coping, and limited social support can adversely affect the psychological well-being of HIV-infected adolescents, particularly sexual minority youth with behaviorally acquired HIV.

    Interactions with the physical world are deeply rooted in our sense of touch and depend on ensembles of somatosensory neurons that invade and innervate the skin. Somatosensory neurons convert the mechanical energy delivered in each touch into excitatory membrane currents carried by mechanoelectrical transduction (MeT) channels. Pacinian corpuscles in mammals and touch receptor neurons (TRNs) in Caenorhabditis elegans nematodes are embedded in distinctive specialized accessory structures, have low thresholds for activation, and adapt rapidly to the application and removal of mechanical loads. Recently, many of the protein partners that form native MeT channels in these and other somatosensory neurons have been identified. However, the biophysical mechanism of symmetric responses to the onset and offset of mechanical stimulation has eluded understanding for decades. Moreover, it is not known whether applied force or the resulting indentation activate MeT channels. Here, we introduce a system for simultaneously recording membrane current, applied force, and the resulting indentation in living C. elegans (Feedback-controlled Application of mechanical Loads Combined with in vivo Neurophysiology, FALCON) and use it, together with modeling, to study these questions. We show that current amplitude increases with indentation, not force, and that fast stimuli evoke larger currents than slower stimuli producing the same or smaller indentation. A model linking body indentation to MeT channel activation through an embedded viscoelastic element reproduces the experimental findings, predicts that the TRNs function as a band-pass mechanical filter, and provides a general mechanism for symmetrical and rapidly adapting MeT channel activation relevant to somatosensory neurons across phyla and submodalities.

    Although HIV-infected men who have sex with men (MSM) constitute a newly emerged high-risk group in China, little research outside Western countries is available on effective intervention programs to enhance their well-being. The purpose of this randomized controlled trial was to evaluate the efficacy of a group intervention program designed to improve the well-being and adaptive coping strategies of 60 HIV-infected MSM in Beijing, China, randomly assigned either to the intervention group for participation in four weekly sessions or to the control group for placement on a waiting list. They all completed measurements at pre- and postintervention. Compared with the control group, the intervention group reported significantly increased problem-focused coping strategies and levels of posttraumatic growth (PTG) as well as decreased symptoms of posttraumatic stress disorder (PTSD) at the completion of the intervention. In addition, mediation analysis showed that changes in problem-focused coping strategies mediated the intervention effect on increases in PTG; however, the mediating effect of coping strategies on the association of intervention and PTSD was not significant. This study provides empirical evidence for conducting psychological intervention to promote the well-being of HIV-infected MSM. The findings also elucidate the mechanism through which intervention improved PTG.

    The COMET-AR User's Manual provides a reference manual for the Computational Structural Mechanics Testbed with Adaptive Refinement (COMET-AR), a software system developed jointly by Lockheed Palo Alto Research Laboratory and NASA Langley Research Center under contract NAS1-18444. The COMET-AR system is an extended version of an earlier finite element based structural analysis system called COMET, also developed by Lockheed and NASA. The primary extensions are the adaptive mesh refinement capabilities and a new "object-like" database interface that makes COMET-AR easier to extend further. This User's Manual provides a detailed description of the user interface to COMET-AR from the viewpoint of a structural analyst.

  6. Adaptive plasma for cancer therapy: physics, mechanism and applications

    One of the most promising applications of cold atmospheric plasma (CAP) is the cancer therapy. The uniqueness of plasma is in its ability to change composition in situ. Plasma self-organization could lead to formation of coherent plasma structures. These coherent structures tend to modulate plasma chemistry and composition, including reactive species, the electric field and charged particles. Formation of coherent plasma structures allows the plasma to adapt to external boundary conditions, such as different cells types and their contextual tissues. In this talk we will explore possibilities and opportunities that the adaptive plasma therapeutic system might offer. We shall define such an adaptive system as a plasma device that is able to adjust the plasma composition to obtain optimal desirable outcomes through its interaction with cells and tissues. The efficacy of cold plasma in a pre-clinical model of various cancer types such as lung, bladder, breast, head, neck, brain and skin has been demonstrated. Both in-vitro and in-vivo studies revealed that cold plasmas selectively kill cancer cells. Recently mechanism of plasma selectivity based on aquaporin hypothesis has been proposed. Aquaporins (AQPs) are the confirmed membrane channels of H2O2 and other large molecules. We have demonstrated that the anti-cancer capacity of plasma could be inhibited by silencing the expression of AQPs. Additional possible cell feedback mechanism was recently discovered. It is associated with production of reactive species during direct CAP treatment by cancer cells. Selective production of hydrogen peroxide by different cells can lead to adaptation of chemistry at the plasma-cell interface based on the cellular input. In particular we have found that the discharge voltage is an important factor affecting the ratio of reactive oxygen species to reactive nitrogen species in the gas phase and this correlates well with effect of hydrogen peroxide production by cells.

    In the USA, HIV-positive Black men who have sex with men show large disparities in disease outcomes compared to other racial/ethnic and risk groups. This study examined the strategies that HIV-positive Black men who have sex with men use to cope with different types of discrimination. A total of 27 HIV-positive Black men who have sex with men participated in semi-structured interviews, which were transcribed verbatim and coded using thematic analysis by multiple raters. Major coping themes included reactive avoidance (using behaviours, cognitions and emotions to escape from discrimination), a common reaction to racism; proactive avoidance (avoiding situations in which discrimination is anticipated), manifested as selective disclosure of HIV-serostatus; external attribution for discrimination (versus self-blame), used more for sexual orientation and HIV discrimination; and social support-seeking, which most often emerged in response to racism. Active coping strategies, such as self-advocacy (countering discrimination directly or indirectly), were infrequently reported. Findings suggest a need for structural anti-discrimination interventions, in tandem with culturally congruent individual- or group-level interventions that aim to enhance men's existing adaptive coping strategies.

    We examined a brief educational intervention addressing hand hygiene self-regulatory mechanisms, and evaluated which psychological mechanisms may lead to hand hygiene behaviours. Two hundred forty two students (mean age = 21 years, SD = 3.9) received either an experimental (n = 149) or a control condition on action control and planning (n = 93). Hand hygiene, coping planning, and action control were measured at baseline and six weeks later. By applying repeated measures ANOVA, we compared the experimental condition addressing planning to perform hand hygiene with a control condition. Additionally, working mechanisms were evaluated by means of mediation analysis. The intervention had an effect on action control, as reflected by a time by treatment interaction. The direct effect of the intervention on behaviour was, however, non-significant. Changes in action control led to changes in coping planning. These social-cognitive changes mediated the effect of intervention on behaviour, after controlling for gender, baseline behaviour, and classroom membership. In spite of the associations between the intervention and self-regulatory strategies, no direct effect was found of the intervention on behaviour. Further research on how to increase hand sanitizing, involving enviromental characteristics, is required. The intervention led only indirectly to an improvement of hand hygiene via changes in self-regulatory factors. Results indicate the importance of promoting action control and coping planning to initiate changes in hand hygienic behaviours.

    Patients having psychiatric diagnoses often experience high level of distress. Religiousness is often used by them as part of their coping mechanism and problem-solving strategies. To determine the level of religious commitment and coping methods in psychiatric patients and its relationship with distress level. Religious commitment and coping patterns were measured with the Duke University Religious Index (DUREL) and Brief RCOPE, respectively. Psychopathology was assessed using the Brief Psychiatric Rating Scale (BPRS) and distress level was assessed with the Depressive, Anxiety and Stress Scale (DASS). Social support and experiences of recent threatening events were measured with the Multidimensional Scale of Perceived Social Support (MSPSS) and Life Threatening Events (LTE). A total of 228 patients were included in this study with a mean age of 40.2 years. The majority were male, Malay, Muslim, single and with psychotic disorder. The subjects had a high level of religious commitment and had used more positive coping methods. Negative religious coping, psychiatric symptoms and diagnosis of anxiety disorder or major depression were significantly associated with high distress level. Higher religious commitment was significantly associated with lower distress (p < .05). Psychiatric patients were religiously committed and used more positive religious coping methods. Practices of negative religious coping, severe psychiatric symptoms and anxiety/depression were associated with higher distress.

    To appraise and synthesise empirical studies examining sources of occupational stress and ways of coping utilised by nurse managers when dealing with stress. The Nurse Manager's role is challenging yet draining and stressful and has adverse consequences on an individual's overall health and well-being, patients' outcomes and organisational productivity. Considerable research has been carried out; however, an updated and broader perspective on this critical organisational issue has not been performed. An integrative review. Five databases (Cumulative Index to Nursing and Allied Health Literature, SCOPUS, PubMed, PsychINFO and MEDLINE) were searched to identify relevant articles. Search terms and MeSH terms included: "charge nurse," "coping," "coping strategy," "coping style," "psychological adaptation," "psychological stress," "stressors," "nurse manager" and "unit manager." Twenty-two articles were included in this review. Reporting followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement guidelines. Four themes were identified: moderate stress levels, common sources of stress, ways of coping and the impact of nurses' characteristics on stress. Nurse managers experienced moderate levels of stress mainly from heavy workloads, lack of resources and financial responsibilities. Enhancing social support and promoting job control were seen as important in reducing work stress and its related consequences. Additional studies using a more rigorous method and a larger sample size preferably in multicultural settings would shed more light on this topic. Hospital and nurse administrators play an important role in promoting supportive structures for daily professional practice for nurse managers through staffing, organisational resources, support services, leadership and stress management training. © 2017 John Wiley & Sons Ltd.

    2006-10-01

    The goals of the study were to identify adaptational phenomena in running mechanics over a variety of surfaces due to age related changes in the muscle-tendon units (MTUs) capacities, to examine whether running experience is associated with adaptational effects on running mechanics over a variety of surfaces even at old age, and to investigate whether surface condition affects running mechanics. The investigation was executed on 30 old and 19 young including 29 runners and 20 non-active subjects. In a previous study we documented that the older had lower MTUs capacities. In the present study running mechanics were analysed as the same subjects ran at 2.7 m/s over three surfaces having different compliance. Surface condition did not affect centre of mass trajectory, duty factor or joint kinetics (P > 0.01). Older react to the reduced MTUs capacity by increasing duty factor and benefiting from a mechanical advantage for the triceps surae MTU and a lower rate of force generation on all surfaces (P < 0.01). Runners displayed lower average horizontal forces and a higher mechanical advantage for the quadriceps femoris MTU for all surfaces (P < 0.01). The results provided strong evidence on that running strategy remained essentially unchanged over a variety of surfaces. Adaptive improvements in running mechanics due to task experience were present for all surfaces and did not depend on age. We further concluded that older adults were able to recalibrate their running strategy to adjust the task effort to the reduced MTUs capacities in a feedforward control manner for a variety of mechanical environments.

    Endometriosis is a disabling and long-term medical condition affecting quality of life and mental health. Behavioral, cognitive, and emotional coping strategies, emotional intelligence, and metacognition could in part explain the link between the disease and impaired psychological and life functioning. This critical narrative review aimed at examining the state of the art of the relationships between endometriosis and these factors. According to PRISMA principles, we performed a systematic search for quantitative and qualitative studies on multiple electronic databases as regards coping strategies, emotional intelligence, and metacognition in women with endometriosis. Studies were subjected to interpretative and critical narrative synthesis. A total of 9 papers were included in the review. Three main categories were identified in thematic analysis and resumed in the manuscript. Findings suggested that (a) pain is considered the major stressor; (b) they usually use both adaptive and maladaptive coping strategies; (c) women with endometriosis and related chronic pain seem to repress emotions more likely than healthy ones; (d) suppressing own emotions, pain catastrophizing, and having a passive coping style are related to higher self-reported pain; and (e) emotional and avoidance coping styles are associated to poor mental status, while positive coping strategies focusing on the problem or on emotions, detached and rational styles are associated to better mental health. Few studies with mixed results and some methodological flaws have focused on coping strategies in women with endometriosis. No studies focusing on metacognition or emotional intelligence were found. Methodological biases, suggestions for future research, and implications for clinical practice were discussed.

    The relationship among weight-related coping, guilt, and shame was investigated in a sample of 98 obese German individuals over a 6-month period. In terms of the objectives, the study explored the kind and frequency of typical coping situations in which obese individuals become aware of being obese. Furthermore, the study sought to determine the predictive utility of weight-related shame and guilt concerning coping responses, and to establish whether there is an association between coping responses and weight change. A longitudinal examination over a 6-month period was chosen with two measurement points. As typical distressing coping situations, individuals reported mostly negative evaluations through others/self, physical exercise situations, or environmental hazards (mainly shopping for clothes). Weight-related shame at baseline was a significant negative predictor for problem-focused engagement coping, whereas weight-related guilt was a significant positive predictor for problem-focused engagement strategies and dietary restraint at follow-up. Although Body Mass Index showed no substantial association with the coping measures, weight loss was accompanied by a substantial drop in problem-focused disengagement coping (wishful thinking, problem avoidance). Discussion of these findings focuses on the issue of possible effects of weight-related feelings of guilt and shame on coping behavior, the link between weight loss and disengaging coping strategies, and the possible use of the findings for cognitive-behavioral therapy for obesity.

    The present study examines changes in defense maturity from mid to late life using data from an over 70-year longitudinal study. A sample of 72 men was followed beginning in late adolescence. Participants' childhoods were coded for emotional warmth. Defense mechanisms were coded by independent raters using the Q-Sort of Defenses (, Ego mechanisms of defense: A guide for clinicians and researchers 217-233) based on interview data gathered at approximately ages 52 and 75. We examined psychosocial correlates of defenses at midlife, late life, and changes in defense from mid to late life. Overall, defenses grew more adaptive from midlife to late life. However, results differed on the basis of the emotional warmth experienced in the participants' childhoods. In midlife, men who experienced warm childhoods used more adaptive (mature) defenses; yet by late life, this difference in defensive maturity had disappeared. Men who experienced less childhood warmth were more likely to show an increase in adaptive defenses during the period from mid to late life.

    Numerous studies have investigated the effect of Interactive Cancer Communication Systems (ICCSs) on system users' improvements in psychosocial status. Research in this area, however, has focused mostly on cancer patients, rather than on caregivers, and on the direct effects of ICCSs on improved outcomes, rather than on the psychological mechanisms of ICCS effects. To understand the underlying mechanisms, this study examines the mediating role of perceived caregiver bonding in the relation between one ICCS (the Comprehensive Health Enhancement Support System [CHESS]) use and caregivers' coping strategies. To test the hypotheses, a secondary analysis of data was conducted on 246 caregivers of lung cancer patients. These caregivers were randomly assigned to (a) the Internet, with links to high-quality lung cancer websites, or (b) access to CHESS, which integrated information, communication, and interactive coaching tools. Findings suggest that perceived bonding has positive effects on caregivers' appraisal and problem-focused coping strategies, and it mediates the effect of ICCS on the coping strategies 6 months after the intervention has begun.

    Rigorous Verification and Validation (V&V) techniques are essential for high assurance systems. Lately, the performance of some of these systems is enhanced by embedded adaptive components in order to cope with environmental changes. Although the ability of adapting is appealing, it actually poses a problem in terms of V&V. Since uncertainties induced by environmental changes have a significant impact on system behavior, the applicability of conventional V&V techniques is limited. In safety-critical applications such as flight control system, the mechanisms of change must be observed, diagnosed, accommodated and well understood prior to deployment. In this paper, we propose a non-conventional V&V approach suitable for online adaptive systems. We apply our approach to an intelligent flight control system that employs a particular type of Neural Networks (NN) as the adaptive learning paradigm. Presented methodology consists of a novelty detection technique and online stability monitoring tools. The novelty detection technique is based on Support Vector Data Description that detects novel (abnormal) data patterns. The Online Stability Monitoring tools based on Lyapunov's Stability Theory detect unstable learning behavior in neural networks. Cases studies based on a high fidelity simulator of NASA's Intelligent Flight Control System demonstrate a successful application of the presented V&V methodology. ,

    The purpose of this article is to describe a Roy adaptation model based- research abstraction, the findings of which were synthesized into a middle-range theory (MRT) of adaptive spirituality. The published literature yielded 21 empirical studies that investigated religion/spirituality. Quantitative results supported the influence of spirituality on quality of life, psychosocial adjustment, well-being, adaptive coping, and the self-concept mode. Qualitative findings showed the importance of spiritual expressions, values, and beliefs in adapting to chronic illness, bereavement, death, and other life transitions. These findings were abstracted into six theoretical statements, a conceptual definition of adaptive spirituality, and three hypotheses for future testing. © The Author(s) 2016.

  1. Postreceptoral chromatic-adaptation mechanisms in the red-green and blue-yellow systems using simple reaction times

    Simple visual-reaction times (VRT) were measured for a variety of stimuli selected along red-green (L-M axis) and blue-yellow [S-(L+M) axis] directions in the isoluminant plane under different adaptation stimuli. Data were plotted in terms of the RMS cone contrast in contrast-threshold units. For each opponent system, a modified Piéron function was fitted in each experimental configuration and on all adaptation stimuli. A single function did not account for all the data, confirming the existence of separate postreceptoral adaptation mechanisms in each opponent system under suprathreshold conditions. The analysis of the VRT-hazard functions suggested that both color-opponent mechanisms present a well-defined, transient-sustained structure at marked suprathreshold conditions. The influence of signal polarity and chromatic adaptation on each color axis proves the existence of asymmetries in the integrated hazard functions, suggesting separate detection mechanisms for each pole (red, green, blue, and yellow detectors).

    Abstract The primary aim of the present study was to examine the extent to which the effects of coping on adjustment are moderated by levels of event controllability. Specifically, the research tested two revisions to the goodness of fit model of coping effectiveness. First, it was hypothesized that the effects of problem management coping (but not problem appraisal coping) would be moderated by levels of event controllability. Second, it was hypothesized that the effects of emotion-focused coping would be moderated by event controllability, but only in the acute phase of a stressful encounter. To test these predictions, a longitudinal study was undertaken (185 undergraduate students participated in all three stages of the research). Measures of initial adjustment (low depression and coping efficacy) were obtained at Time 1. Four weeks later (Time 2), coping responses to a current or a recent stressor were assessed. Based on subjects' descriptions of the event, objective and subjective measures of event controllability were also obtained. Measures of concurrent and subsequent adjustment were obtained at Times 2 and 3 (two weeks later), respectively. There was only weak support for the goodness of fit model of coping effectiveness. The beneficial effects of a high proportion of problem management coping (relative to total coping efforts) on Time 3 perceptions of coping efficacy were more evident in high control than in low control situations. Other results of the research revealed that, irrespective of the controllability of the event, problem appraisal coping strategies and emotion-focused strategies (escapism and self-denigration) were associated with high and low levels of concurrent adjustment, respectively. The effects of these coping responses on subsequent adjustment were mediated through concurrent levels of adjustment.

  3. Mechanisms of Drug Resistance: Daptomycin Resistance

    Daptomycin (DAP) is a cyclic lipopeptide with in vitro activity against a variety of Gram-positive pathogens, including multidrug-resistant organisms. Since its introduction in clinical practice in 2003, DAP has become an important key front-line antibiotic for severe or deep-seated infections caused by Gram-positive organisms. Unfortunately, DAP-resistance (R) has been extensively documented in clinically important organisms such as Staphylococcus aureus, Enterococcus spp, and Streptococcus spp. Studies on the mechanisms of DAP-R in Bacillus subtilis and other Gram-positive bacteria indicate that the genetic pathways of DAP resistance are diverse and complex. However, a common phenomenon emerging from these mechanistic studies is that DAP-R is associated with important adaptive changes in cell wall and cell membrane homeostasis with critical changes in cell physiology. Findings related to these adaptive changes have offered novel insights into the genetics and molecular mechanisms of bacterial cell envelope stress response and the manner in which Gram-positive bacteria cope with the antimicrobial peptide attack and protect vital structures of the cell envelope such as the cell membrane. In this review, we will examine the most recent findings related to the molecular mechanisms of resistance to DAP in relevant Gram-positive pathogens and discuss the clinical implications for therapy against these important bacteria.

    Pain is a complex construct that contributes to profound physical and psychological dysfunction, particularly in individuals coping with chronic pain. The current paper builds upon previous research, describes a balanced conceptual model that integrates aspects of both psychological vulnerability and resilience to pain, and reviews protective and exacerbating psychosocial factors to the process of adaptation to chronic pain, including pain catastrophizing, pain acceptance, and positive psychological resources predictive of enhanced pain coping. The current paper identifies future directions for research that will further enrich the understanding of pain adaptation and espouses an approach that will enhance the ecological validity of psychological pain coping models, including introduction of advanced statistical and conceptual models that integrate behavioral, cognitive, information processing, motivational and affective theories of pain.

    Epidemiologic studies conducted in Western societies show poorer sleep quality in women compared with men. Socioeconomic and stress-related psychological variables have been shown to influence sleep, but not much is known about sociological and psychological influences on the sleep of women in general and non-Western women in particular. The present study reports on sociodemographic and coping variables in relation to sleep quality in female Moroccan immigrants living in Germany. Participants took part in a structured personal interview on Pittsburg Sleep Quality Inventory (PSQI) sleep quality, coping style preferences, and information related to the degree of identification with Western life style. Sleep quality was poor (PSQI > 6) in 39% of women. Surprisingly, women who had identified with a more Western lifestyle had poorer sleep quality than women who had retained their traditional Moroccan life style. An unusually large proportion of women preferred monitoring (i.e., information-seeking coping style) and adaptive coping (48% and 19%, respectively), regardless of sleep quality. Monitoring was more frequent in women who were less integrated into German culture. Results on sleep quality suggest that for Moroccan immigrant women in Germany, adopting a Western life style may be more stressful than retaining their native life style. The high preference for an information seeking approach in coping may reflect the desire for information rather than actual coping behavior.

    Low-income urban children of color are at elevated risk for poor asthma control. This cross-sectional study examined associations among parents' coping (primary control, secondary control, and disengagement), parental depressive symptoms, and children's asthma outcomes (asthma control and school attendance) in a predominantly low-income, racially/ethnically diverse sample of families. Parents (N = 78; 90% female) of children (33% female; 46% Black; 38% Latino) aged 5-17 years (M = 9.5 years) reported on their own coping and depressive symptoms, their child's asthma control, and full and partial days of school missed due to asthma. Parents' secondary control coping (i.e., coping efforts to accommodate/adapt to asthma-related stressors) was negatively correlated, and disengagement coping (i.e. coping efforts to avoid/detach from stressors) was positively correlated, with their depressive symptoms. Secondary control coping was also correlated with fewer partial days of school missed. Primary control coping (i.e., coping efforts to change stressors) was not associated with depressive symptoms or asthma outcomes. Parents' depressive symptoms were also positively correlated with poorer asthma control and partial days of school missed. Regression models showed direct and indirect effects of secondary control and disengagement coping on asthma outcomes via depressive symptoms, after controlling for demographic factors. Parents' secondary control and disengagement coping are related to children's asthma outcomes. Secondary control coping may support parents' mental health and children's asthma control in low-income urban families.

    When someone has a mental illness, family members may share the experience of stigma. Past research has established that family members' experiences of stigma by association predict psychological distress and lower quality-of-life. The present study, conducted with 503 family members of people with mental illness examined the prevalence of 14 different coping strategies. Of greater importance, we examined the role of these coping strategies as mediators of the relationships between stigma by association and family burden, on the one hand, and outcomes, such as psychological distress and quality-of-life, on the other. The results showed that both perceived stigma by association and family burden are associated with greater psychological distress and lower quality-of-life, and that most coping strategies mediate these relationships. Adaptive coping strategies were related to reduced negative outcomes, while most maladaptive coping strategies were related to enhanced negative outcomes. Implications for intervention development are discussed.

    End-stage renal disease (ESRD) is an irreversible and life-threatening condition. In Jordan, the number of ESRD patients treated with hemodialysis is on the rise. Identifying stressors and coping strategies used by patients with ESRD may help nurses and health care providers to gain a clearer understanding of the condition of these patients and thus institute effective care planning. The purpose of this study was to identify stressors perceived by Jordanian patients on hemodialysis, and the coping strategies used by them. A convenience sample of 131 Jordanian men and women was recruited from outpatients' dialysis units in four hospitals. Stressors perceived by participants on hemodialysis and the coping strategies were measured using Hemodialysis Stressor Scale, and Ways of Coping Scale-Revised. Findings showed that patients on hemodialysis psychosocial stressors scores mean was higher than the physiological stressors mean. Positive reappraisal coping strategy had the highest mean among the coping strategies and the lowest mean was accepting responsibility. Attention should be focused towards the psychosocial stressors of patients on hemodialysis and also helping patients utilize the coping strategies that help to alleviate the stressors. The most used coping strategy was positive reappraisal strategy which includes faith and prayer.

    Whether perceived or enacted, HIV-related stigma is widespread in India, and has had a crippling effect on People Living with HIV/AIDS (PLHA). Research has shown that a positive attitude towards the illness sets a proactive framework for the individual to cope with his or her infection; therefore, healthy coping mechanisms are essential to combat HIV-related stigma. This qualitative study involving in-depth interviews and focus group discussions with PLHA affiliated with HIV support groups in South India explored positive coping strategies employed by PLHA to deal with HIV-related stigma. Interviews and focus group discussions were translated, transcribed, and analyzed for consistent themes. Taboos surrounding modes of transmission, perceiving sex workers as responsible for the spread of HIV, and avoiding associating with PLHA provided the context of HIV-related stigma. Despite these challenges, PLHA used several positive strategies, classified as Clear Knowledge and Understanding of HIV, Social Support and Family Well-Being, Selective Disclosure, Employment Building Confidence, and Participation in Positive Networks. Poor understanding of HIV and fears of being labeled immoral undermined healthy coping behavior, while improved understanding, affiliation with support groups, family support, presence of children, and financial independence enhanced PLHA confidence. Such positive coping behaviours could inform culturally relevant interventions.

    Nowadays, family members are gradually taking on the role of full-time caregivers for patients suffering from schizophrenia. The increasing burden and tasks of caretaking can cause them psychological distress such as depression or anxiety. The aim of this study was to measure the correlation between perceived stigma and coping, and psychological distress as well as determine the predictors of psychological distress among the caregivers. Results showed that 31.5% of the caregivers experienced psychological distress. “Community rejection” was found to be positively associated with psychological distress. In case of coping subscales, psychological distress had a positive correlation with substance use, use of emotional support, behavioral disengagement, venting, and self-blame, while it was negatively correlated with “positive reframing”. Behavioral disengagement was the best predictor of psychological distress among caregivers of patients with schizophrenia, followed by positive reframing, use of emotional support, self-blame, and venting. Health practitioners can use adaptive coping strategies instead of maladaptive for caregivers to help ease their distress and prevent further deterioration of psychological disorders. PMID:27574475

    Nurses utilize transcultural, transactional, systems, primary, and interdisciplinary approaches to physiological and psychosocial components of patient care. Expanded roles, as well as advances in knowledge and technology have prepared nurses for critical, specialized, primary, aerospace, and independent nursing practice. Exciting as they are, nursing's expanded roles and practices frequently contribute to the burnout and distress phenomena increasingly observed in practicing health care professionals. Causes and symptoms of the burnout distress phenomena are many and varied. Selye, Shubin, Maslach, and others adeptly identified and wrote on the phenomena as it specifically relates to nurses and the many facets of nursing practice. Rather than utilizing crisis intervention coping techniques, preventive strategies and adaptations are suggested. This paper reviews and discusses: 1. Factors associated with burnout-distress phenomena identified in professional literature; 2. Identification of factors associated with expanded roles and practice which contribute to burnout stress; 3. Identification of factors in military and civilian air ambulance and aeromedical evacuation systems which contribute to burnout stress; 4. Recommendations for strategies to prevent and cope with burnout distress factors.

    When a child is born, the life of the family changes significantly and each of its members must adapt to the new situation. When the child is born with a disability, in addition to regular adaptation, the family must cope with stress, grief, disappointments, and challenges, which may lead to a serious crisis or even disruption of family life. Parents must coordinate assessments, evaluations, and various treatments while maintaining contact with many professionals and numerous institutions or services. They find themselves faced with important decisions on behalf of the child, decisions on management of the child with disability, and economic decisions that will affect the whole family. This paper reviews the literature on the topic of coping when a child with disability is born and also studies the question as to whether a connection exists between parental orientation toward feelings of guilt and the family relationships system. The event of a child born with a disability is always a tragedy for the family, but early intervention and support may help the family to adjust and become positively involved in the care and development of the child, even if that child is different and in need of special treatment.

    Phenomenon: Medical students' coping abilities are important for academic success and emotional health. The authors explored differences in students' use of active, problem-solving strategies and emotional, inwardly directed approaches; the change in coping strategies used during medical school; and coping strategy impact on performance. One hundred eighty-three students completed the Ways of Coping Scale at matriculation and end of the 2nd and 3rd years. Frequency of each of 8 ways of coping, changes in coping strategy use over time, and relationship of coping method with preclinical and clinical scores were calculated. Students varied widely in use of coping mechanisms. Over time, students shifted to using emotional strategies more frequently while decreasing their use of active strategies. Coping strategies were unrelated to preclinical academic performance (R 2 = .09, adjusted R 2 = .04, ns) but were related to clinical performance (R 2 = .23, adjusted R 2 = .18, p < .0001), with active coping associated with higher performance and emotional methods associated with lower performance. Insights: Students decreased use of active coping strategies and increased use of emotional coping strategies over time, but emotional strategies were associated with poorer clinical academic performance. These shifts in coping methods may be detrimental to student performance and learning. Improving students' ability to cope should be an educational priority.

    Theories about how couples help each other to cope with stress, such as the systemic transactional model of dyadic coping, suggest that the cultural context in which couples live influences how their coping behavior affects their relationship satisfaction. In contrast to the theoretical assumptions, a recent meta-analysis provides evidence that neither culture, nor gender, influences the association between dyadic coping and relationship satisfaction, at least based on their samples of couples living in North America and West Europe. Thus, it is an open questions whether the theoretical assumptions of cultural influences are false or whether cultural influences on couple behavior just occur in cultures outside of the Western world. In order to examine the cultural influence, using a sample of married individuals (N = 7973) from 35 nations, we used multilevel modeling to test whether the positive association between dyadic coping and relationship satisfaction varies across nations and whether gender might moderate the association. RESULTS reveal that the association between dyadic coping and relationship satisfaction varies between nations. In addition, results show that in some nations the association is higher for men and in other nations it is higher for women. Cultural and gender differences across the globe influence how couples' coping behavior affects relationship outcomes. This crucial finding indicates that couple relationship education programs and interventions need to be culturally adapted, as skill trainings such as dyadic coping lead to differential effects on relationship satisfaction based on the culture in which couples live.

    We observed gendered coping strategies and conflict resolution outcomes used by adolescents and parents during a conflict discussion task to evaluate associations with current and later adolescent psychopathology. We studied 137 middle- to upper-middle-class, predominantly Caucasian families of adolescents (aged 11-16 years, 65 males) who represented a range of psychological functioning, including normative, subclinical, and clinical levels of problems. Adolescent coping strategies played key roles both in the extent to which parent-adolescent dyads resolved conflict and in the trajectory of psychopathology symptom severity over a 2-year period. Gender-prototypic adaptive coping strategies were observed in parents but not youth, (i.e., more problem solving by fathers than mothers and more regulated emotion-focused coping by mothers than fathers). Youth-mother dyads more often achieved full resolution of conflict than youth-father dyads. There were generally not bidirectional effects among youth and parents' coping across the discussion except boys' initial use of angry/hostile coping predicted fathers' angry/hostile coping. The child was more influential than the parent on conflict resolution. This extended to exacerbation/alleviation of psychopathology over 2 years: higher conflict resolution mediated the association of adolescents' use of problem-focused coping with decreases in symptom severity over time. Lower conflict resolution mediated the association of adolescents' use of angry/hostile emotion coping with increases in symptom severity over time. Implications of findings are considered within a broadened context of the nature of coping and conflict resolution in youth-parent interactions, as well as on how these processes impact youth well-being and dysfunction over time.

    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.

    Background & objectives: Psychosocial stressors leading to allostatic load need to be explored further as these have great scope for early intervention. Stress studies done in India are mostly based on sources of stress and objective measures of stress. Therefore, the objective of the present study was to assess stress appraisal among students (16-17 yr) and to identify institution-specific differences (Private vs. Government) in stress appraisal and coping. Methods: The study was carried out among 16-17 yr old apparently normal students. Eighty students were recruited from six schools ensuring equal representation from gender/category of schools (Government/ Private). Validated and culturally adaptable behavioural scales for perceived stress (PSS), stressful life events (LES) and coping were administered. Psychological morbidity was assessed using GHQ-12. Data on 75 students were available for statistical analysis. Results: The students of both Government and Private schools showed similar stress perception, though the former tend to have a higher mean score. The scores were significantly higher on avoidance coping (P<0.05). The stepwise regression model showed coping as the independent predictor of perceived stress (R2= 10%). Interpretation & conclusions: Students from Government schools had significantly higher scores on avoidance coping and therefore, suitable for a systematic study on chronic stress for early intervention.

    Taking into account the regional context, we investigated whether social comparison in coping with occupational uncertainty served self-improvement (i.e., adaptive coping) or self-enhancement (i.e., subjective well-being). Respondents were 620 German adults aged 16 to 43, 59% female, who participated in three yearly follow-ups of a larger survey. The number of observations was 1,309 for contemporaneous and 1,079 for longitudinal analyses. Participants reported on perceived occupational uncertainty (e.g., risk of losing a job and difficulties with career planning), strategies for coping with it, and whether, and in which direction, they made social comparisons in coping with occupational uncertainty. Making social comparisons (vs. not) was associated with higher goal engagement and lower goal disengagement. Upward (as opposed to downward) comparison prospectively predicted higher goal engagement. Under high regional unemployment, upward comparison prospectively predicted lower goal disengagement, whereas making social comparisons was contemporaneously associated with higher subjective well-being. Higher regional unemployment rates predicted more frequent comparison, whereas comparison direction was predicted only by situational variables, especially personal control over the outcomes. When operationalized as a conscious mental action and put in the context of coping with occupational uncertainty, social comparison serves primarily self-improvement. © 2017 Wiley Periodicals, Inc.

    Single mothers, especially those on social assistance, report significantly more depressive symptoms than the general public. This article examines the relationships among employment status, stressful life events, and depressive symptoms among single mothers, with a special focus on the potential mediating and moderating roles of coping repertoire. Cross-sectional survey design. Ninety-six single mothers (48 employed and 48 single mothers on social assistance) who were the primary caregiver for at least 1 child 4-18 years old. Mailed questionnaires that included an adapted version of the Social Readjustment Rating Scale, the Coping Strategy Inventory, and the Beck Depression Inventory, 2nd ed. were completed by study participants. Coping repertoire did not mediate the relationship between either employment status or stress exposure and depressive symptoms. Coping had an antagonistic and differential moderating effect on the association between employment status and depressive symptoms for employed single mothers and mothers receiving social assistance. Effective strategies aimed at promoting single mothers' mental health need to address both the severity of depressive symptoms found among single mothers, and the social-system factors that threaten single mothers' psychological well-being. The implications for practice and policy are discussed.

    A key feature of neural networks is their ability to rapidly adjust their function, including signal gain and temporal dynamics, in response to changes in sensory inputs. These adjustments are thought to be important for optimizing the sensitivity of the system, yet their mechanisms remain poorly understood. We studied adaptive changes in temporal integration in direction-selective cells in macaque primary visual cortex, where specific hypotheses have been proposed to account for rapid adaptation. By independently stimulating direction-specific channels, we found that the control of temporal integration of motion at one direction was independent of motion signals driven at the orthogonal direction. We also found that individual neurons can simultaneously support two different profiles of temporal integration for motion in orthogonal directions. These findings rule out a broad range of adaptive mechanisms as being key to the control of temporal integration, including untuned normalization and nonlinearities of spike generation and somatic adaptation in the recorded direction-selective cells. Such mechanisms are too broadly tuned, or occur too far downstream, to explain the channel-specific and multiplexed temporal integration that we observe in single neurons. Instead, we are compelled to conclude that parallel processing pathways are involved, and we demonstrate one such circuit using a computer model. This solution allows processing in different direction/orientation channels to be separately optimized and is sensible given that, under typical motion conditions (e.g., translation or looming), speed on the retina is a function of the orientation of image components. Many neurons in visual cortex are understood in terms of their spatial and temporal receptive fields. It is now known that the spatiotemporal integration underlying visual responses is not fixed but depends on the visual input. For example, neurons that respond selectively to motion direction integrate

    Extracellular matrix and cells are inherent in coordinating and adapting to each other during all physiological and pathological processes. Synthetic materials, however, show rarely reciprocal and spatiotemporal responses to cells, and lacking self-adapting properties as well. Here, a mechanical adaptability based on the matrix metalloproteinase (MMPs) sensitive polyelectrolyte film is reported. Poly-lysine (PLL) and methacrylated hyaluronic acid (HA-MA) nanolayers are employed to build the thin film through the layer-by-layer assembly, and it is further crosslinked using MMP sensitive peptides, which endows the films with changeable mechanical properties in response to MMPs. It is demonstrated that stiffness of the (PLL/HA-MA) films increases with the crosslinking, and then decreases in response to a treatment of enzyme. Consequently, the crosslinked (PLL/HA-MA) films reveal effective growth of endothelial cells (ECs), leading to fast formation of EC monolayer. Importantly, significantly improved endothelial function of the EC monolayer, which is characterized by integrity, biomolecules release, expression of function related gene, and antithrombotic properties, is achieved along with the decrosslinking of the film because of EC-secreted MMPs. These results suggest that mechanical adaptability of substrate in Young's modulus plays a significant role in endothelial progression, which shows great application potential in tissue engineering, regenerative medicine, and organ-on-a-chip. © 2017 WILEY-VCH Verlag GmbH & Co.

    Japanese medaka (Oryzias latipes) is a freshwater (FW) teleost that is popular throughout the world for laboratory use. In this paper, we discuss the utility of Japanese medaka and related species for studying mechanisms of seawater (SW) adaptation. In addition to general advantages as an experimental animal such as their daily spawning activity, transparency of embryos, short generation time and established transgenic techniques, Japanese medaka have some adaptability to SW unlike the strictly stenohaline zebrafish (Danio rerio). Since other species in the genus Oryzias exhibit different degrees of adaptability to SW, comparative studies between Japanese medaka, where molecular-biological and genetic information is abundant, and other Oryzias species are expected to present varying approaches to solving the problems of SW adaptation. We introduce some examples of interspecies comparison for SW adaptabilities both in adult fish and in embryos. Oryzias species are good models for evolutionary, ecological and zoogeographical studies and a relationship between SW adaptability and geographic distribution has been suggested. Medaka fishes may thus deliver new insights into our understanding of how fish have expanded their distribution to a wide variety of osmotic environments.

    Tissues and cells sustain recurring mechanical loads that span a wide range of loading amplitudes and timescales as a consequence of exposure to blood flow, muscle activity, and external impact. Both tissues and cells derive their mechanical strength from fibrous protein scaffolds, which typically have a complex hierarchical structure. In this study, we focus on a prototypical hierarchical biomaterial, fibrin, which is one of the most resilient naturally occurring biopolymers and forms the structural scaffold of blood clots. We show how fibrous networks composed of fibrin utilize irreversible changes in their hierarchical structure at different scales to maintain reversible stress stiffening up to large strains. To trace the origin of this paradoxical resilience, we systematically tuned the microstructural parameters of fibrin and used a combination of optical tweezers and fluorescence microscopy to measure the interactions of single fibrin fibers for the first time, to our knowledge. We demonstrate that fibrin networks adapt to moderate strains by remodeling at the network scale through the spontaneous formation of new bonds between fibers, whereas they adapt to high strains by plastic remodeling of the fibers themselves. This multiscale adaptation mechanism endows fibrin gels with the remarkable ability to sustain recurring loads due to shear flows and wound stretching. Our findings therefore reveal a microscopic mechanism by which tissues and cells can balance elastic nonlinearity and plasticity, and thus can provide microstructural insights into cell-driven remodeling of tissues.

    Objectives This study examined predictors of treatment expectation among osteoarthritis (OA) patients in a multi-site clinical trial of pain coping strategies training (CST). Methods Patients (N=171) completed a pre-treatment assessment battery that asked questions about treatment expectations, pain coping variables, pain, physical function, psychological distress, quality of life, and depression as well as background demographic and medical variables. Results Regression analyses indicated that several variables accounted for 21% of the variance in treatment expectations (p < .0001). Patients who were classified as adaptive copers, reported higher self efficacy and social interaction, had higher quality of life, and who had lower levels of affective distress and depression had more positive expectations about engaging in pain coping skills training. Variables that were not associated with treatment expectation were level of pain and physical dysfunction, duration of disease, and disability status as well as demographic variables. Discussion Thus, while many OA patients will approach pain coping skills training with positive expectations, others have lower expectations. This study suggests that a multidimensional assessment of OA patients with chronic pain can identify those who have higher expectations versus lower expectations. The results suggest that patients who are psychologically distressed are less optimistic about engaging in treatment and that these patients, in particular, may benefit from and need pre-treatment motivational interviewing to enhance their uptake of pain coping skills PMID:21178591

    The present study was conducted to assess the problems faced by adolescents whose parents suffer from major mental illness at selected mental health institutes of Delhi. The objectives also included assessment of the coping strategies of the adolescents in dealing with these problems. The Stuart Stress Adaptation Model of Psychiatric Nursing Care was used as the conceptual framework. A descriptive survey approach with cross-sectional design was used in the study. A structured interview schedule was prepared. Purposive non-probability sampling technique was employed to interview 50 adolescents whose parents suffer from major mental illness. Data gathered was analysed and interpreted using both descriptive and inferential statistics. The study showed that majority of the adolescents had moderate problems as a result of their parent's mental illness. Area-wise analysis of the problems revealed that the highest problems faced were in family relationship and support and majority of the adolescents used maladaptive coping strategies. A set of guidelines on effective coping strategies was disseminated to these adolescents.

    This study reports on 170 Israeli school children at risk for missile attack during the Persian Gulf War. The Bar-Ilan Picture Test for Children (Itskowitz & Strauss, 1982, 1986) was specially adapted to the war situation specifically to measure children's affective reactions and coping strategies. Children with a greater sense of control and social support, and more complex defenses, tended to demonstrate better coping strategies. Children who were less defensive showed higher levels of anxiety under stress. Children scoring higher in social support showed greater perceived control over their immediate environment and more verbal expressivity with respect to the crisis situation. Girls scored higher than boys on emotional and verbal expressiveness. These data, elicited through semiprojective procedures, are consistent with much of the prior research based mainly on objective scales or self-report questionnaires. Overall, the results lend additional validity to the nexus of relations (largely established through conventional objective scales) between resources, coping, and outcomes in a naturalistic stressor situation.

    Rule-based diagnostic expert systems can be used to perform many of the diagnostic chores necessary in today's complex space systems. These expert systems typically take a set of symptoms as input and produce diagnostic advice as output. The primary objective of such expert systems is to provide accurate and comprehensive advice which can be used to help return the space system in question to nominal operation. The development and maintenance of diagnostic expert systems is time and labor intensive since the services of both knowledge engineer(s) and domain expert(s) are required. The use of adaptive learning mechanisms to increment evaluate and refine rules promises to reduce both time and labor costs associated with such systems. This paper describes the basic adaptive learning mechanisms of strengthening, weakening, generalization, discrimination, and discovery. Next basic strategies are discussed for adding these learning mechanisms to rule-based diagnostic expert systems. These strategies support the incremental evaluation and refinement of rules in the knowledge base by comparing the set of advice given by the expert system (A) with the correct diagnosis (C). Techniques are described for selecting those rules in the in the knowledge base which should participate in adaptive learning. The strategies presented may be used with a wide variety of learning algorithms. Further, these strategies are applicable to a large number of rule-based diagnostic expert systems. They may be used to provide either immediate or deferred updating of the knowledge base.

  13. Preferential Osmolyte Accumulation: a Mechanism of Osmotic Stress Adaptation in Diazotrophic Bacteria

    A common cellular mechanism of osmotic-stress adaptation is the intracellular accumulation of organic solutes (osmolytes). We investigated the mechanism of osmotic adaptation in the diazotrophic bacteria Azotobacter chroococcum, Azospirillum brasilense, and Klebsiella pneumoniae, which are adversely affected by high osmotic strength (i.e., soil salinity and/or drought). We used natural-abundance 13C nuclear magnetic resonance spectroscopy to identify all the osmolytes accumulating in these strains during osmotic stress generated by 0.5 M NaCl. Evidence is presented for the accumulation of trehalose and glutamate in Azotobacter chroococcum ZSM4, proline and glutamate in Azospirillum brasilense SHS6, and trehalose and proline in K. pneumoniae. Glycine betaine was accumulated in all strains grown in culture media containing yeast extract as the sole nitrogen source. Alternative nitrogen sources (e.g., NH4Cl or casamino acids) in the culture medium did not result in measurable glycine betaine accumulation. We suggest that the mechanism of osmotic adaptation in these organisms entails the accumulation of osmolytes in hyperosmotically stressed cells resulting from either enhanced uptake from the medium (of glycine betaine, proline, and glutamate) or increased net biosynthesis (of trehalose, proline, and glutamate) or both. The preferred osmolyte in Azotobacter chroococcum ZSM4 shifted from glutamate to trehalose as a consequence of a prolonged osmotic stress. Also, the dominant osmolyte in Azospirillum brasilense SHS6 shifted from glutamate to proline accumulation as the osmotic strength of the medium increased. PMID:16348295

  14. A molecular mechanism of adaptation in an estuarine copepod

    NASA Astrophysics Data System (ADS)

    The estuarine copepod Eurytemora affinis (Poppe) has been shown to adapt better at the individual (physiological) and population (genetic) level to rapidly cycling environments than to slowly cycling temperatures. In addition, female copepods are physiologically more flexible than males. Three questions arise from these observations. Why is the geographical and seasonal distribution of Eurytemora in estuaries so limited? Why is the genetic variance so high in an organism which is so physiologically flexible? And does the difference between sexes help to explain the maintenance of genetic variance? A mechanism of adaptation which may allow further examination of these questions is the increased synthesis of stress proteins, first identified as heat shock proteins (HSP). The HSPs in the copepod Eurytemora affinis are quantitatively and qualitatively related to stress. Temperature and osmotic stress, for example, induce different sets of proteins. Thus, better understanding the phenomenon may be useful in marine ecology.

  18. Mechanisms and functional implications of motoneuron adaptations to increased physical activity.

    Motoneurons demonstrate adaptations in their physiological properties to alterations in chronic activity levels. The most consistent change that appears to result from endurance-type exercise training is the reduced excitatory current required to initiate and maintain rhythmic firing. While the precise mechanisms through which these neurons adapt to activity are currently unknown, evidence exists that adaptation may involve alterations in the expression of genes that code for membrane receptors which can influence the responses of neurons to transmitters during activation. The influence of these adaptations may also extend to the resting condition, where ambient levels of neuroactive substances may influence ion conductances at rest, and thus result in the activation or inhibition of specific ion conductances that underlie the measurements of increased excitability that have been reported for motoneurons in the anesthetised state. We have applied motoneuron excitability and muscle unit contractile changes with endurance training to a mathematical computerised model of motor unit recruitment (Heckman and Binder, 1991). The results from the modelling exercise demonstrate increased task efficiency at relative levels of effort during a submaximal contraction. The physiological impact that nerve and muscle adaptations have on the neuromuscular system during standardized tasks seem to fit with reported changes in motor unit behaviour in trained human subjects.

    As one of the most prevalent diseases globally and as an important cause of disability, depressive disorders are responsible for as many as one in every five visits to primary care doctors. Cultural variations in clinical presentation, sometimes make it difficult to recognize the disorder resulting in patients not being diagnosed and not receiving appropriate treatment. To address this issue, we conducted a qualitative pilot study on three ethnic groups including Fars, Kurdish, and Turkish in Iran to test the use of qualitative methods in exploring the explanatory models of help-seeking and coping with depression (without psychotic feature) among Iranian women. A qualitative study design was used based on an explanatory model of illness framework. Individual interviews were conducted with key informant (n=6), and depressed female patients (n=6). A hypothetical case vignette was also used in focus group discussions and individual interviews with lay people (three focus groups including 25 participants and six individual interviews; n=31). There were a few differences regarding help-seeking and coping mechanisms among the three ethnic groups studied. The most striking differences were in the area of treatment. Non-psychotic depressive disorder in all ethnicities was related to an external stressor, and symptoms of illness were viewed as a response to an event in the social world. Coping mechanisms involved two strategies: (1) solving problems by seeking social support from family and neighbors, religious practice, and engaging in pleasurable activities, and (2) seeking medical support from psychologists and family counselors. The Fars group was far more likely to recommend professional treatment and visiting psychiatrists whereas the other two ethnic groups (i.e., Turks and Kurds) preferred to consult family counselors, psychologists or other alternative care providers, and traditional healers. The study has educational and clinical implications. Cultural reframing
