    This study explores the relative contribution of the overall quality of attachment to the mother, to the father and to peers (Inventory of Parent and Peer Attachment scales), the style of attachment towards peers (Attachment Questionnaire for Children scale), the social rank variables (submissive behavior and social comparison), and sex and age variables in predicting the depression score (Center of Epidemiological Studies Depression Scale) on a non-psychiatric sample of 13-18 year old adolescents (n = 225). Results of our integrated model (adjusted R-Square of .50) show that attachment variables (overall quality of attachment to the father and to the mother), social rank variables (social comparison and submissive behavior), age and sex are important in predicting depressive symptoms during adolescence. Moreover, the attachment to peers variables (quality of attachment to peers, secure and ambivalent style of attachment) and sex are mediated by the social rank variables (social comparison and submissive behavior).

    This study compared the peer functioning of a community sample of preschool boys with pervasive hyperactivity (N=33) and comparison boys (N=34), and examined the extent to which any differences in peer functioning between these groups could be explained by comorbid child conduct problems and parenting factors. The quality of boys' peer relations…

    Early pubertal timing has received considerable empirical support as a risk for adolescent substance use. However, few studies have examined the mediators linking these variables. Therefore, the aims of this study were (1) to examine peer substance use as a mediator between pubertal timing and adolescent substance use longitudinally and (2) to test gender and maltreatment experience as moderators of the mediational model. Data were obtained from time 1, 2, and 3 of a longitudinal study of maltreatment and development. At time 1 the sample was comprised of 303 maltreated and 151 comparison children aged 9-13 years (213 females and 241 males). Longitudinal mediation was tested using structural equation modeling and moderating effects were tested using multiple group analysis. Peer substance use mediated the relationship between early pubertal timing and later adolescent substance use for the total sample. Moderation analyses indicated this significant indirect effect did not differ for males and females. However, it did differ for maltreated versus comparison adolescents with the mediational effect only remaining significant for the comparison group. This is one of the first studies to examine peer substance use as a mediator of pubertal timing and adolescent substance use using a longitudinal design. Early maturing males are at equal risk to early maturing females for interacting with peers that may draw them into substance use. Additionally, the findings indicate that while peers are mediators for comparison adolescents a different mechanism may link early puberty to substance use for maltreated adolescents.

    We set out to evaluate the friendships and social behaviour of school-aged children with migraine. Concern exists regarding the impact of paediatric migraine on daily activities and quality of life. We hypothesized that children with migraine would have fewer friends and be identified as more socially sensitive and isolated than comparison peers. Sixty-nine children with migraine participated in a school-based study of social functioning. A comparison sample without migraine included classmates matched for gender, race and age. Children with migraine had fewer friends at school; however, this effect was limited to those in elementary school. Behavioural difficulties were not found. Middle-school students with migraine were identified by peers as displaying higher levels of leadership and popularity than comparison peers. Concern may be warranted about the social functioning of pre-adolescent children with migraine; however, older children with migraine may function as well as or better than their peers.

    Department of Veterans Affairs (VA) peer specialists and vocational rehabilitation specialists are Veterans employed in mental health services to help other Veterans with similar histories and experiences. Study objectives were to (a) examine job satisfaction among these employees, (b) compare them to other VA mental health workers, and (c) identify factors associated with job satisfaction across the 3 cohorts. The study sample included 152 VA-employed peer specialists and 222 vocational rehabilitation specialists. A comparison group included 460 VA employees from the same job categories. All participants completed the Job Satisfaction Index (11 aspects and overall satisfaction ratings). Linear regression was used to compare job satisfaction and identify its predictors among the 3 cohorts. Job satisfaction was fairly high, averaging "somewhat satisfied" to "very satisfied" in 6 (peer specialists) and 9 (vocational rehabilitation specialists) of the 11 aspects and overall job ratings. Adjusting for length of employment, age and gender resulted in no significant group differences with 2 exceptions: White peer specialists were less satisfied with pay and promotion opportunities than vocational rehabilitation specialists and comparison-group employees. Across all cohorts, shorter length of time employed in the job was associated with higher job satisfaction. The high job satisfaction levels among the 2 peer cohorts suggest support for the policy of hiring peer specialists in the VA. Furthermore, the results are consistent with those of the nonveteran samples, indicating that integrating peer providers into mental health care is possible in VA and non-VA settings.

    This study examined the Dieting Peer Competitiveness Scale; it is an instrument for evaluating this social comparison in young people. This instrumental study has two aims: The objective of the first aim was to present preliminary psychometric data from the Spanish version of the Dieting Peer Competitiveness Scale, including statistical item analysis, research about this instrument's internal structure, and a reliability analysis, from a sample of 1067 secondary school adolescents. The second objective of the study corresponds to confirmatory factor analysis of the scale's internal structure, as well as analysis for evidence of validity from a sample of 1075 adolescents.

  7. Effects of a school-based sexuality education program on peer educators: the Teen PEP model.

    2014-04-01

    This study evaluated the impact of the Teen Prevention Education Program (Teen PEP), a peer-led sexuality education program designed to prevent unintended pregnancy and sexually transmitted infections (STIs) including HIV among high school students. The study design was a quasi-experimental, nonrandomized design conducted from May 2007 to May 2008. The sample consisted of 96 intervention (i.e. Teen PEP peer educators) and 61 comparison students from five high schools in New Jersey. Baseline and 12-month follow-up surveys were conducted. Summary statistics were generated and multiple regression analyses were conducted. In the primary intent-to-treat analyses, and secondary non-intent-to-treat analyses, Teen PEP peer educators (versus comparison students) reported significantly greater opportunities to practice sexual risk reduction skills and higher intentions to talk with friends, parents, and sex partners about sex and birth control, set boundaries with sex partners, and ask a partner to be tested for STIs including HIV. In addition in the secondary analysis, Teen PEP peer educators (as compared with the comparison students) had significantly higher scores on knowledge of sexual health issues and ability to refuse risky sexual situations. School-based sexuality education programs offering comprehensive training to peer educators may improve sexual risk behavior knowledge, attitudes and behaviors among high school students.

    This experiment examined the cognitive and emotional impact of two social comparison-based sun protection interventions in a sample of Southern California college students (N = 223). One of the interventions employed comparison UV photos of peers who had either much more (downward social comparison) or much less (upward social comparison) skin damage than did participants themselves. The second intervention consisted of descriptive norms information suggesting that a large majority of the participants' peer group regularly protect their skin from the sun. Participants were randomly assigned to one of eight conditions in a 4 (Social Comparison Information: no photo vs. no comparison photos vs. upward comparison photos vs. downward comparison photos) × 2 (Descriptive Norms Information: Received vs. not received) design. Emotional reactions (e.g. worry, embarrassment, relief) and sun-related cognitive reactions (perceived susceptibility, sun protection intentions) were assessed immediately. Sun protection behaviours were assessed in a surprise telephone follow-up five weeks following the intervention. The results demonstrated that the combination of seeing photos of peers who had very little sun damage and learning that a majority of one's peers engage in regular sun protection resulted in reliably greater subsequent sun protection than all other conditions. Further, there was relatively direct evidence that both negative emotional reactions and sun protection intentions mediated this effect. These findings add to the growing literature suggesting the importance of thoroughly examining the role of emotions in health behaviour decisions. Both theory and intervention efficacy would benefit from a better understanding of the relative role of cognitions and emotions in behaviour change.

    The aim was to assess the romantic and peer relationships of bariatric surgery candidates and associations with health behaviors. Adults seeking bariatric surgery (N = 120) completed surveys addressing health behaviors and social relationships at information sessions. Analysis was done to compare male/female differences in peer and romantic relationships and associations with health behaviors. Previously published reference (REF) data on the Relationship Structures questionnaire was used for comparison, and to split our sample into those ≤ or > REF mean for relationship anxiety and avoidance. Our sample reported higher avoidance and lower anxiety in their close friendships and romantic relationships compared to the REF sample. Men in our sample had higher peer and romantic relationships avoidance compared to the REF sample and had significantly higher close friendship avoidance than women in our sample. Participants with lower anxiety in their romantic relationships (≤ REF) had higher uncontrolled eating and physical activity; those with more anxiety in their romantic relationships (> REF) had a higher BMI. Our findings highlight the potential influence that social relationships may have on health behaviors within the bariatric surgery population. Further investigation is warranted to explore male bariatric surgery candidates' relationships to inform understanding and intervention development.

    The purpose of the current study was to assess the uniqueness of the condition of kidney transplant recipients in comparison to a sample of matching healthy peers in relation to body-image dissatisfaction and identification, quality of life and psychological distress. Participants were 45 kidney transplant recipients who were under follow-up care at a Transplant Unit of a major Medical Center, and a sample of 45 matching healthy peers. Measures were taken using self-report questionnaires [Body-Image Ideals Questionnaire (BIIQ), Body Identification Questionnaire (BIQ), Brief Symptoms Inventory (BSI), and the SF-12]. The major findings were the following: (i) kidney transplant recipients reported lower levels of quality of life and higher levels of PsD when compared to their healthy peers; (ii) no difference in body-image dissatisfaction was found between the two studied groups; (iii) significant correlations between body-image dissatisfaction quality of life and PsD were found only in the kidney transplant recipients. The kidney transplantation condition has a moderating effect in the association between body-image dissatisfaction PsD but not in the association between body-image dissatisfaction and quality of life; (iv) kidney transplant recipients experienced higher levels of body identification than did their healthy peers. Taken together, these findings highlight the unique condition of kidney transplant recipients, as well as the function that body-image plays within the self.

    A systematic review of risk factors for intimate partner violence was conducted. Inclusion criteria included publication in a peer-reviewed journal, a representative community sample or a clinical sample with a control-group comparison, a response rate of at least 50%, use of a physical or sexual violence outcome measure, and control of confounding factors in the analyses. A total of 228 articles were included (170 articles with adult and 58 with adolescent samples). Organized by levels of a dynamic developmental systems perspective, risk factors included: (a) contextual characteristics of partners (demographic, neighborhood, community and school factors), (b) developmental characteristics and behaviors of the partners (e.g., family, peer, psychological/behavioral, and cognitive factors), and (c) relationship influences and interactional patterns. Comparisons to a prior review highlight developments in the field in the past 10 years. Recommendations for intervention and policy along with future directions for intimate partner violence (IPV) risk factor research are presented. PMID:22754606

  13. Predictors of Adolescent Functioning in Girls with Attention-deficit/Hyperactivity Disorder (ADHD): The Role of Childhood ADHD, Conduct Problems, and Peer Status

    Predictors of adolescent functioning were studied in an ethnically diverse sample of girls with attention-deficit/hyperactivity disorder (ADHD) (n = 140) and age- and ethnicity-matched comparison girls (n = 88) who participated in naturalistic summer programs during childhood. Over a five-year follow-up (sample retention = 92%; age range = 11.3–18.2 years), conduct problems were predicted by hyperactivity-impulsivity (HI) symptoms and noncompliance (NC). Academic achievement was predicted only by inattention symptoms, whereas school suspensions/expulsions were predicted by inattention symptoms (ADHD sample only), NC, and negative peer status. Substance use was predicted by NC and HI symptoms. Internalizing problems were predicted by HI symptoms, noncompliance, and covert antisocial behavior. Finally, initial peer status was the only significant predictor of later negative social preference. PMID:16836474

    Antibiotics are a front-line weapon against many infectious diseases. However, antibiotic overuse is the key driver of drug resistance. Previously published studies have suggested benefits of using peer-to-peer education, working with group leaders to build trust and maintain confidentiality within a quality initiative. We hypothesized that working with physicians as a peer group might be beneficial in influencing antibiotic prescribing patterns. To describe and evaluate a peer group model for an intervention to reduce the volume of antibiotic prescriptions among physicians with above average prescribing rates serving an Arab community in northern Israel. Primary care physicians in a defined geographic area who served Arab communities and had high antibiotic prescribing rates--defined as above average number of antibiotic prescriptions per office visit compared with regional and organizational averages--were recruited for the intervention. All other physicians from the same region served as a comparison group. The intervention was administered during 2007 and was completed in early 2008. Four structured meetings scheduled 2 months apart, in which the group explored the issues related to antibiotic overuse, included the following topics: adherence to clinical guidelines; the special position physicians serving Arab communities hold and the influence it has on their practices; pressure due to consumer demands; and suggestions for possible strategies to face ethnic sensitivity, mainly because of the special ties the physicians have with their communities. T-tests for independent samples were used to perform between-group comparisons for each quarter and year of observation from 2006 through 2010, and t-tests for paired samples were used to compare pre-intervention with post-intervention antibiotic prescribing rates. In the 2006 pre-intervention period, the antibiotic prescribing rates were 0.17 for the peer group (n = 11 physicians) and 0.15 for the comparison group (n = 72 physicians, P = 0.279). In 2008 following the intervention, rates were 0.12 and 0.14, respectively (P = 0.396). In the paired t-test analysis, rates declined significantly from 2006 to 2008 in the intervention group (P < 0.001) but not in the comparison group (P = 0.138). Antibiotic prescribing rates remained similar in 2009 and 2010. In the context of a community with special ethnic and cultural characteristics, an intervention relying on peer group techniques was associated with a modest reduction in the volume of antibiotic prescriptions.

    This research examined whether comparison target moderates the effects of naturally occurring appearance-focused social comparisons on women's affect, appearance esteem, and dieting thoughts. During daily activities, body-satisfied (BS) women and body-dissatisfied (BD) women recorded their comparison targets and reactions to comparison information. For BS women, upward comparisons with peers were associated with more positive affect (PA) and appearance esteem and less guilt than upward comparisons with media images and downward comparisons with peers were associated with less PA than downward comparisons with media images. For BD women, upward comparisons with peers were associated with more appearance esteem and diet thoughts than upward comparisons with media images and downward comparisons with peers were associated with less PA, appearance esteem, and diet thoughts and more guilt than downward comparisons with media images.

    Friendships matter for withdrawn youth because the consequences of peer isolation are severe. From a normative sample of 2,437 fifth-graders (1,245 females; M age = 10.25), a subset (n = 1364; 638 female) was classified into three groups (anxious-solitary, unsociable, comparison) and followed across a school year. Findings indicated that it was more common for unsociable than anxious-solitary children to have friends, be stably friended, and participate in multiple friendships. For withdrawn as well as non-withdrawn children, peer rejection predicted friendlessness, but this relation was strongest for anxious-solitary children. The friends of unsociable youth were more accepted by peers than those of anxious-solitary youth. The premise that friendship inhibits peer victimization was substantiated for withdrawn as well as non-withdrawn youth. PMID:21883155

    2014-01-01

    This study investigated the potential mediating roles of body comparisons with peers and models in the relationship between the internalization of thinness norms and body image concern. A total of 224 Western Australian girls aged 14-15 completed questionnaires assessing their endorsement of thinness norms, body image concerns, and frequency of body comparisons with peers and with models. Both targets of body comparisons were found to significantly mediate the relationship between the endorsement of thinness norms and body image concern, with body comparison with peers a stronger mediator than comparison with models. These findings show that body comparison with peers, in particular, plays a significant role in the experience of body image concerns among adolescent girls, and should be given a higher profile in programs designed to prevent or reduce body image concern.

    Objective Social psychological theories provide bases for understanding how social comparison processes may impact peer influence. This study examined two peer characteristics that may impact peer influence on adolescent girls’ weight-related behavior intentions: body size and popularity. Method A school-based sample of 66 9th grade girls (12–15 years old) completed an experimental paradigm in which they believed they were interacting with other students (i.e., “e-confederates”). The body size and popularity of the e-confederates were experimentally manipulated. Participants were randomly assigned to one of the three experimental conditions in which they were exposed to identical maladaptive weight-related behavior norms communicated by ostensible female peers who were either: (1) Thin and Popular; (2) Thin and Average Popularity; or (3) Heavy and Average Popularity. Participants’ intent to engage in weight-related behaviors was measured pre-experiment and during public and private segments of the experiment. Results A significant effect of condition on public conformity was observed. Participants exposed to peers’ maladaptive weight-related behavior norms in the Heavy and Average condition reported significantly less intent to engage in weight-related behaviors than participants in either of the thin-peer conditions (F(2) = 3.93, p = .025). Peer influence on private acceptance of weight-related behavior intentions was similar across conditions (F(2) = .47, p = .63). Discussion Body size comparison may be the most salient component of peer influence processes on weight-related behaviors. Peer influence on weight-related behavior intention also appears to impact private beliefs. Considering peer norms in preventive interventions combined with dissonance-based approaches may be useful.

    Social comparison theory is relevant for learning in general. In a clinical context, we examined four hypotheses concerning: preferred other to compare with, preferred direction of comparison, response to social comparison and influence of personal social comparison orientation (SCO). To investigate the relevance of social comparison for clinical workplace learning. Students (n = 437) from nine different hospitals completed two questionnaires measuring their SCO and the direction of and response to their comparisons. t-tests were used to analyse the data. Students substantially did compare. They preferred to compare with peer students more than with residents or staff, and with peers doing better more than with peers doing worse. Their response to social comparison was more often stimulating for learning than discouraging. Students high in SCO reported a stronger stimulating and discouraging response to their comparisons than students low in SCO. Social comparison does play a role in clinical workplace learning. The mainly stimulating response to social comparison indicates a positive learning influence. The preferred comparison with peers emphasizes the role of peers in the learning process. Further research should focus on student comparison behaviour and on situations that strengthen the positive effects of social comparison and reduce the negative or obstructing ones.

    To examine the effectiveness of a targeted training approach to foster and support a peer-professional workforce in the delivery of a community rehabilitation program for adults with acquired brain injury (ABI) and their families. A prospective longitudinal design was used to evaluate the effectiveness of a targeted two-day training forum for peer (n = 25) and professional (n = 15) leaders of the Skills to Enable People and Communities Program. Leaders completed a set of questionnaires (General Self-Efficacy Scale - GSES, Rosenberg Self-Esteem Scale, Volunteer Motivation Inventory - VMI and Community Involvement Scale - CIS) both prior to and immediately following the forum. Data analysis entailed paired sample t-test to explore changes in scores over time, and independent sample t-tests for comparisons between the two participant groups. The results indicated a significant increase in scores over time for the GSES (p = 0.047). Improvements in leaders' volunteer motivations and community involvement were also observed between the two time intervals. The between group comparisons highlighted that the peer leader group scored significantly higher than the professional leader group on the CIS and several domains of the VMI at both time intervals. The study provides an enhanced understanding of the utility of innovative workforce solutions for community rehabilitation after ABI; and further highlights the benefits of targeted training approaches to support the development of such workforce configurations.

    Children with attention deficit hyperactivity disorder (ADHD) experience many peer interaction problems and are at risk of peer rejection and victimisation. Although many studies have investigated problematic peer functioning in children with ADHD, this research has predominantly focused on boys and studies investigating girls are scant. Those studies that did examine girls, often used a male comparison sample, disregarding the inherent gender differences between girls and boys. Previous studies have highlighted this limitation and recommended the need for comparisons between ADHD females and typical females, in order to elucidate the picture of female ADHD with regards to problematic peer functioning. The aim of this literature review was to gain insight into peer functioning difficulties in school-aged girls with ADHD. PsychINFO, PubMed, and Web of Knowledge were searched for relevant literature comparing school-aged girls with ADHD to typically developing girls (TDs) in relation to peer functioning. The peer relationship domains were grouped into 'friendship', 'peer status', 'social skills/competence', and 'peer victimisation and bullying'. In total, thirteen studies were included in the review. All of the thirteen studies included reported that girls with ADHD, compared to TD girls, demonstrated increased difficulties in the domains of friendship, peer interaction, social skills and functioning, peer victimization and externalising behaviour. Studies consistently showed small to medium effects for lower rates of friendship participation and stability in girls with ADHD relative to TD girls. Higher levels of peer rejection with small to large effect sizes were reported in all studies, which were predicted by girls' conduct problems. Peer rejection in turn predicted poor social adjustment and a host of problem behaviours. Very high levels of peer victimisation were present in girls with ADHD with large effect sizes. Further, very high levels of social impairment and social skills deficits, with large effect sizes, were found across all studies. Levels of pro-social behaviour varied across studies, but were mostly lower in girls with ADHD, with small to large effect sizes. Overall, social disability was significantly higher among girls with ADHD than among TD girls. Congruous evidence was found for peer functioning difficulties in the peer relationship domains of friendship, peer status, social skills/competence, and peer victimisation and bullying in girls with ADHD.

    During clinical rotations, students move from one clinical situation to another. Questions exist about students' strategies for coping with these transitions. These strategies may include a process of social comparison because in this context it offers the student an opportunity to estimate his or her abilities to master a novel rotation. These estimates are relevant for learning and performance because they are related to self-efficacy. We investigated whether student estimates of their own future performance are influenced by the performance level and gender of the peer with whom the student compares him- or herself. We designed an experimental study in which participating students (n = 321) were divided into groups assigned to 12 different conditions. Each condition entailed a written comparison situation in which a peer student had completed the rotation the participant was required to undertake next. Differences between conditions were determined by the performance level (worse, similar or better) and gender of the comparison peer. The overall grade achieved by the comparison peer remained the same in all conditions. We asked participants to estimate their own future performance in that novel rotation. Differences between their estimates were analysed using analysis of variance (ANOVA). Students' estimates of their future performance were highest when the comparison peer was presented as performing less well and lowest when the comparison peer was presented as performing better (p < 0.001). Estimates of male and female students in same-gender comparison conditions did not differ. In two of three opposite-gender conditions, male students' estimates were higher than those of females (p < 0.001 and p < 0.05, respectively). Social comparison influences students' estimates of their future performance in a novel rotation. The effect depends on the performance level and gender of the comparison peer. This indicates that comparisons against particular peers may strengthen or diminish a student's self-efficacy, which, in turn, may ease or hamper the student's learning during clinical rotations. The study is limited by its experimental design. Future research should focus on students' comparison behaviour in real transitions. © Blackwell Publishing Ltd 2013.

    Objective This study examined social functioning among siblings of children with cancer. Method A case–control design was applied to school- and home-based data from multiple informants (peers, teachers, mothers, and self). Social reputation and peer acceptance within the classroom was compared for 87 siblings (aged 8–16 years) and 256 demographically matched peers. Self-perceptions of peer relationships and parent-reported social competence were examined among 67 siblings and 67 matched comparisons.  Results Peer reports (N = 1,633) indicated no differences between siblings and comparisons for social reputation, number of friendships, reciprocated friendships, or peer acceptance. Self-reported prosocial behavior and teacher-reported likability were higher for siblings than comparisons. Self-reported loneliness, friendship quality, and perceived social support did not differ between groups. Mothers reported less involvement in activities and poorer school performance for siblings than comparisons. Conclusions Peer relationships of siblings of children with cancer are similar to classmates, though they experience small decrements in activity participation and school performance.

    The purpose of this study was to evaluate the Drug Prevention in Youth risk reduction program that was implemented in shelters for runaway/homeless youths in the Southeastern United States. The program focuses on knowledge, attitudes and skills that can help this group of high risk young people minimize the serious negative consequences of drug abuse. An evaluation strategy was developed so comparisons could be made between peer-led, adult-led and non-intervention groups. Dependent samples t tests and least squares ANCOVAS were used to measure pretest-posttest differences both within and between groups. Results indicate that the peer-led groups were more successful than the other two groups, and that program effects were the most powerful with the youngest group of shelter clients. Process evaluation revealed important factors related to group leader training and group management. It is concluded that well-trained and motivated peer/near peer leaders have particularly valuable contributions to make with regard to drug abuse risk reduction for shelter clients.

    The degree to which media contributes to body dissatisfaction, life satisfaction and eating disorder symptoms in teenage girls continues to be debated. The current study examines television, social media and peer competition influences on body dissatisfaction, eating disorder symptoms and life satisfaction in a sample of 237 mostly Hispanic girls. 101 of these girls were reassessed in a later 6-month follow-up. Neither television exposure to thin ideal media nor social media predicted negative outcomes either concurrently nor prospectively with the exception of a small concurrent correlation between social media use and life satisfaction. Social media use was found to contribute to later peer competition in prospective analysis, however, suggesting potential indirect but not direct effects on body related outcomes. Peer competition proved to be a moderate strong predictor of negative outcomes both concurrently and prospectively. It is concluded that the negative influences of social comparison are focused on peers rather than television or social media exposure.

    Both sensation seeking and affiliation with deviant peer groups are risk factors for delinquency in adolescence. In this study, we use a sample of adolescent twins (n = 549), 13 to 20 years old (M age = 15.8 years), in order to test the interactive effects of peer deviance and sensation seeking on delinquency in a genetically informative design. Consistent with a socialization effect, affiliation with deviant peers was associated with higher delinquency even after controlling for selection effects using a co-twin-control comparison. At the same time, there was evidence for person-environment correlation; adolescents with genetic dispositions toward higher sensation seeking were more likely to report having deviant peer groups. Genetic influences on sensation seeking substantially overlapped with genetic influences on adolescent delinquency. Finally, the environmentally mediated effect of peer deviance on adolescent delinquency was moderated by individual differences in sensation seeking. Adolescents reporting high levels of sensation seeking were more susceptible to deviant peers, a Person × Environment interaction. These results are consistent with both selection and socialization processes in adolescent peer relationships, and they highlight the role of sensation seeking as an intermediary phenotype for genetic risk for delinquency.

    2013-01-01

    To evaluate the effects of a high school peer educator training programme on the sexual behaviour and related psychosocial outcomes of peer educators. A total of 728 students from 15 randomly selected public high schools in the Western Cape, South Africa, with a peer education programme and 15 matched comparison schools were recruited, comprising 295 students in the intervention group and 433 students in the comparison arms of the study respectively. Age of sexual debut, use of condom at last sex and psychosocial outcomes such as decision making, goal orientation, critical thinking and self-esteem were measured at baseline and follow-up 18 months later. At follow-up, there were no significant differences in the age of sexual debut, use of condom at last sex, goal orientation, critical thinking and self-esteem scores of the peer educators compared to students in the comparison group. Decision-making scores were significantly higher in the peer educators, compared to students in the comparison group (adjusted difference between means 0.14, 95% CI 0.02 to 0.26). Even a highly intensive peer education training programme had limited effects for the peer educators themselves. It is clear that community factors, gendered power relations and poverty need to be addressed to have a lasting impact.

    To investigate whether adolescents who were born extremely preterm (<26 weeks gestation), very preterm (<32 weeks gestation), or with very low birth weight (<1500 g) are more often bullied, and whether this contributes to higher emotional problem scores. We used 2 whole population samples: the German Bavarian Longitudinal Study (BLS) (287 very preterm/very low birth weight and 293 term comparison children) and the UK EPICure Study (183 extremely preterm and 102 term comparison children). Peer bullying was assessed by parent report in both cohorts at school years 2 and 6/7. The primary outcome was emotional problems in year 6/7. The effects of prematurity and bullying on emotional problems were investigated with regression analysis and controlled for sex, socioeconomic status, disability, and preexisting emotional problems. Preterm-born children were more often bullied in both cohorts than term comparisons (BLS: relative risk, 1.27; 95% CI, 1.07-1.50; EPICure: relative risk, 1.69; 95% CI, 1.19-2.41). Both preterm birth and being bullied predicted emotional problems, but after controlling for confounders, only being bullied at both ages remained a significant predictor of emotional problem scores in both cohorts (BLS: B, 0.78; 95% CI, 0.28-1.27; P < .01; EPICure: B, 1.55; 95% CI, 0.79-2.30; P < .001). In the EPICure sample, being born preterm and being bullied at just a single time point also predicted emotional problems. Preterm-born children are more vulnerable to being bullied by peers. Those children who experience bullying over years are more likely to develop emotional problems. Health professionals should routinely ask about peer relationships. Copyright © 2015 Elsevier Inc.

    Despite its widespread support, the most effective simulation-based debriefing method has little evidence to support its efficacy. In this study, we compared the effect of peer-led and instructor-led debriefing among nursing students. The study was conducted with a non-equivalent control group using a pretest-post-test design. A convenience sample of third-year nursing students was used for the study, where 65 students enrolled in a 2-week clinical placement rotation were randomly assigned to the instructor-led group or peer-led group. The quality of cardiopulmonary resuscitation skills, satisfaction with simulation, and quality of debriefing in the peer-led group were compared to those in the instructor-led group. Group differences at each testing interval were analyzed using independent t-test. Nursing students in the instructor-led debriefing group showed better subsequent cardiopulmonary resuscitation performance, more satisfaction with simulation experience, and higher debriefing scores compared to the peer-led group. From our study, instructor-led debriefing is an effective method in improving skills performance, inducing favorable satisfaction, and providing better quality of debriefing among nursing students. © 2016 John Wiley & Sons Australia, Ltd.

  16. Social distance, perceived drinking by peers, and alcohol use by college students.

    2006-01-01

    Many colleges in the United States are employing social norms marketing campaigns with the goal of reducing college students' alcohol use by correcting misperceptions about their peers' alcohol use. Although the typical message used in these campaigns describes the quantity and frequency of alcohol use by the average student on campus, many students may find such a vague comparison to others to be socially irrelevant. This study compares the relative weight of perceptions about alcohol use by distant versus proximate peers in the prediction of college students' personal drinking behavior. The results of analyzing data collected from a sample of college students at a large public northeastern university (N=276) show that, as hypothesized, perceived alcohol use by proximate peers (best friends and friends) was a stronger predictor of students' personal alcohol use than perceived alcohol use by more distant peers (such as students in general), controlling for other strong predictors of alcohol use by college students (age, gender, race, off-campus residency, and sensation-seeking tendencies). The implications of these findings for the design of more effective social norms messages are discussed.

    This cross-sectional study investigated whether anxiety and social functioning interact in their prediction of peer victimization. A structural equation model linking anxiety, social skills, and friendship quality to victimization was tested separately for children with anxiety disorders and normal comparison children to explore whether the processes involved in victimization differ for these groups. Participants were 8-14 year old children: 55 (34 boys, 21 girls) diagnosed with an anxiety disorder and 85 (37 boys, 48 girls) normal comparison children. The final models for both groups yielded two independent pathways to victimization: (a) anxiety independently predicted being victimized; and (b) poor social skills predicted lower friendship quality, which in turn, placed a child at risk for victimization. These findings have important implications for the treatment of childhood anxiety disorders and for school-based anti-bullying interventions, but replication with larger samples is indicated.

    Speech-language pathologists who serve clients from cultural backgrounds that are not familiar to them may encounter culturally influenced attitudinal differences. A questionnaire with statements about 4 speech disorders (dysfluency, cleft pallet, speech of the deaf, and misarticulations) was given to a focus group of Chinese Americans and a comparison group of non-Chinese Americans. The focus group was much more likely to believe that persons with speech disorders could improve their own speech by "trying hard," was somewhat more likely to say that people who use deaf speech and people with cleft palates might be "emotionally disturbed," and generally more likely to view deaf speech as a limitation. The comparison group was more pessimistic about stuttering children's acceptance by their peers than was the focus group. The two subject groups agreed about other items, such as the likelihood that older children with articulation problems are "less intelligent" than their peers.

  20. “We wouldn’t of made friends if we didn’t come to Football United”: the impacts of a football program on young people’s peer, prosocial and cross-cultural relationships

    2013-01-01

    Background Sport as a mechanism to build relationships across cultural boundaries and to build positive interactions among young people has often been promoted in the literature. However, robust evaluation of sport-for-development program impacts is limited. This study reports on an impact evaluation of a sport-for-development program in Australia, Football United®. Methods A quasi-experimental mixed methods design was employed using treatment partitioning (different groups compared had different levels of exposure to Football United). A survey was undertaken with 142 young people (average age of 14.7 years with 22.5% of the sample comprising girls) in four Australian schools. These schools included two Football United and two Comparison schools where Football United was not operating. The survey instrument was composed of previously validated measures, including emotional symptoms, peer problems and relationships, prosocial behaviour, other-group orientation, feelings of social inclusion and belonging and resilience. Face to face interviews were undertaken with a purposeful sample (n = 79) of those who completed the survey. The participants in the interviews were selected to provide a diversity of age, gender and cultural backgrounds. Results Young people who participated in Football United showed significantly higher levels of other-group orientation than a Comparison Group (who did not participate in the program). The Football United boys had significantly lower scores on the peer problem scale and significantly higher scores on the prosocial scale than boys in the Comparison Group. Treatment partitioning analyses showed positive, linear associations between other-group orientation and total participation in the Football United program. A lower score on peer problems and higher scores on prosocial behaviour in the survey were associated with regularity of attendance at Football United. These quantitative results are supported by qualitative data analysed from interviews. Conclusions The study provides evidence of the effects of Football United on key domains of peer and prosocial relationships for boys and other-group orientation for young people in the program sites studied. The effects on girls, and the impacts of the program on the broader school environment and at the community level, require further investigation. PMID:23621898

    Use of social media, such as Facebook, is pervasive among young women. Body dissatisfaction is also highly prevalent in this demographic. The present study examined the relationship between Facebook usage and body image concerns among female university students (N=227), and tested whether appearance comparisons on Facebook in general, or comparisons to specific female target groups (family members, close friends, distant peers [women one may know but do not regularly socialize with], celebrities) mediated this relationship. Results showed a positive relationship between Facebook usage and body image concerns, which was mediated by appearance comparisons in general, frequency of comparisons to close friends and distant peers, and by upward comparisons (judging one's own appearance to be worse) to distant peers and celebrities. Thus, young women who spend more time on Facebook may feel more concerned about their body because they compare their appearance to others (especially to peers) on Facebook.

    Despite claims about the universality of religious belief, whether religiosity scales have the same meaning when administered inter-subjectively-or translated and applied cross-culturally-is currently unknown. Using the recent "Supernatural Belief Scale" (SBS), we present a primer on how to verify the strong assumptions of measurement invariance required in research on religion. A comparison of two independent samples, Croatians and New Zealanders, showed that, despite a sophisticated psychometric model, measurement invariance could be demonstrated for the SBS except for two noninvariant intercepts. We present a new approach for inspecting measurement invariance across self- and peer-reports as two dependent samples. Although supernatural beliefs may be hard to observe in others, the measurement model was fully invariant for Croatians and their nominated peers. The results not only establish, for the first time, a valid measure of religious supernatural belief across two groups of different language and culture, but also demonstrate a general invariance test for distinguishable dyad members nested within the same targets. More effort needs to be made to design and validate cross-culturally applicable measures of religiosity.

    To investigate the role of spinal cord injury (SCI) peer mentorship on quality of life (QoL)/participation, and test a self-determination theory model that explains the role of SCI peer mentorship on these outcomes. A static group comparison design. Community. A convenience sample of mentees (individuals receiving peer mentorship) (n=68) and nonmentees (n=63) who had an SCI, were older than 18 years, and spoke either English or French. Mentees: at least 4 peer mentorship sessions over the past 5 years; nonpeer mentees: 0 or 1 brief introductory session. QoL (ie, life satisfaction and positive and negative affect), participation (eg, autonomous indoor; family role), and the psychological needs of autonomy, competence, and relatedness. No group differences were found, but years since injury was a moderator indicating that, generally, peer mentees living with SCI for longer (∼30y) appear to benefit more from peer mentorship interactions compared with nonmentees and mentees living with SCI for approximately 6 years. Competence and relatedness mediated the peer mentorship-outcome relationship for QoL and some participation variables, indicating that peer mentorship predicted competence and relatedness, which in turn were related to the outcomes. Satisfaction of competence and relatedness needs requires greater attention in SCI peer mentorship. Years since injury modified the relationship between peer mentorship and outcomes, which provided new insights on the role of SCI peer mentorship. Further studies are needed to determine SCI peer mentorship-specific outcomes that are important across the years-since-injury spectrum. Copyright © 2017 American Congress of Rehabilitation Medicine.

    2016-03-01

    People are exposed to exemplary peer performances often (and sometimes by design in interventions). In two studies, we showed that exposure to exemplary peer performances can undermine motivation and success by causing people to perceive that they cannot attain their peers' high levels of performance. It also causes de-identification with the relevant domain. We examined such discouragement by peer excellence by exploiting the incidental exposure to peers' abilities that occurs when students are asked to assess each other's work. Study 1 was a natural experiment in a massive open online course that employed peer assessment (N = 5,740). Exposure to exemplary peer performances caused a large proportion of students to quit the course. Study 2 explored underlying psychological mechanisms in an online replication (N = 361). Discouragement by peer excellence has theoretical implications for work on social judgment, social comparison, and reference bias and has practical implications for interventions that induce social comparisons. © The Author(s) 2016.

    1997-10-01

    Because of the centrality of peer relationship difficulties for children with attentiondeficit hyperactivity disorder (ADHD), we investigated behavioral (overt and covert antisocial activity), internalizing (self-reports and observed social isolation), and familial (authoritative, authoritarian, and permissive parenting beliefs) predictors of peer sociometric nominations among previously unfamiliar, ethnically diverse ADHD (N=73) and comparison (N=60) boys, aged 6-12 years. Authoritative maternal parenting beliefs and negatively weighted social isolation explained significant variance in positive peer regard; aggression, covert behavior, and authoritative parenting beliefs were the independent predictors of both negative peer status and peer social preference. We extended such predictions with statistical control of (1) child cognitive variables, (2) maternal psychopathology, and (3) ADHD boys, but authoritative parenting beliefs were stronger predictors in ADHD than in comparison youth. We discuss family-peer linkages regarding peer competence.

    The present study examines discrepancies between self- and adult-perceptions of social competence in children with attention deficit-hyperactivity disorder (ADHD), autism spectrum disorders (ASD) and possible co-morbid disruptive behaviour disorders (DBD). Self-reported questionnaires were collected from multiple informants at the baseline of a multi-systemic family intervention programme for children (aged 5-12) with ADHD, ASD and possible co-morbid DBD. In total, out of the 154 families eligible for the study, information was received concerning children from 124 families (children n = 121; mothers n = 117; fathers n = 86; teachers n = 97). In addition to this, a comparison community sample of 318 school-aged children (approximately 10 years old) was utilized to examine the perceptions of children's social competence across intervention and population groups in more detail. Children's self-perceptions in the prosocial dimension of social competence (i.e. cooperating skills, empathy) did not differ between the intervention and comparison groups. Interestingly, the children in the intervention sample expressed more impulsivity and disruptiveness - the antisocial dimension of social competence - when compared with the children in the comparison sample. Adult ratings demonstrated that mothers, fathers and teachers reported decreased prosocial behaviour and increased antisocial behaviour across overall dimensions and sub-dimensions when compared with adults' ratings of elementary school children. Informant discrepancies between self-ratings and adult ratings across intervention groups yielded significant effect sizes (eta-squared) across all domains of social competence ranging from .09 to .25. Children's positive self-ratings of social competence relative to adult ratings increased within intervention sample when compared with population sample. The intervention sample children appeared to acknowledge their social competence deficits, yet self-perceptions were inflated relative to adult ratings when focusing on peer relationship difficulties, particularly, aggression to peers. © 2016 John Wiley & Sons Ltd.

    Abstract Introduction: Although technology-assisted tobacco interventions (TATIs) are effective, they are underused due to recruitment challenges. We tested whether we could successfully recruit smokers to a TATI using peer marketing through a social network (Facebook). Methods: We recruited smokers on Facebook using online advertisements. These recruited smokers (seeds) and subsequent waves of smokers (peer recruits) were provided the Share2Quit peer recruitment Facebook app and other tools. Smokers were incentivized for up to seven successful peer recruitments and had 30 days to recruit from date of registration. Successful peer recruitment was defined as a peer recruited smoker completing the registration on the TATI following a referral. Our primary questions were (1) whether smokers would recruit other smokers and (2) whether peer recruitment would extend the reach of the intervention to harder-to-reach groups, including those not ready to quit and minority smokers. Results: Overall, 759 smokers were recruited (seeds: 190; peer recruits: 569). Fifteen percent (n = 117) of smokers successfully recruited their peers (seeds: 24.7%; peer recruits: 7.7%) leading to four recruitment waves. Compared to seeds, peer recruits were less likely to be ready to quit (peer recruits 74.2% vs. seeds 95.1%), more likely to be male (67.1% vs. 32.9%), and more likely to be African American (23.8% vs. 10.8%) (p < .01 for all comparisons). Conclusions: Peer marketing quadrupled our engaged smokers and enriched the sample with not-ready-to-quit and African American smokers. Peer recruitment is promising, and our study uncovered several important challenges for future research. Implications: This study demonstrates the successful recruitment of smokers to a TATI using a Facebook-based peer marketing strategy. Smokers on Facebook were willing and able to recruit other smokers to a TATI, yielding a large and diverse population of smokers. PMID:27613918

    Although technology-assisted tobacco interventions (TATIs) are effective, they are underused due to recruitment challenges. We tested whether we could successfully recruit smokers to a TATI using peer marketing through a social network (Facebook). We recruited smokers on Facebook using online advertisements. These recruited smokers (seeds) and subsequent waves of smokers (peer recruits) were provided the Share2Quit peer recruitment Facebook app and other tools. Smokers were incentivized for up to seven successful peer recruitments and had 30 days to recruit from date of registration. Successful peer recruitment was defined as a peer recruited smoker completing the registration on the TATI following a referral. Our primary questions were (1) whether smokers would recruit other smokers and (2) whether peer recruitment would extend the reach of the intervention to harder-to-reach groups, including those not ready to quit and minority smokers. Overall, 759 smokers were recruited (seeds: 190; peer recruits: 569). Fifteen percent (n = 117) of smokers successfully recruited their peers (seeds: 24.7%; peer recruits: 7.7%) leading to four recruitment waves. Compared to seeds, peer recruits were less likely to be ready to quit (peer recruits 74.2% vs. seeds 95.1%), more likely to be male (67.1% vs. 32.9%), and more likely to be African American (23.8% vs. 10.8%) (p < .01 for all comparisons). Peer marketing quadrupled our engaged smokers and enriched the sample with not-ready-to-quit and African American smokers. Peer recruitment is promising, and our study uncovered several important challenges for future research. This study demonstrates the successful recruitment of smokers to a TATI using a Facebook-based peer marketing strategy. Smokers on Facebook were willing and able to recruit other smokers to a TATI, yielding a large and diverse population of smokers. © The Author 2016.

  12. Attentional deficits with and without hyperactivity: teacher and peer perceptions.

    PubMed

    King, C; Young, R D

    1982-12-01

    The present study assessed teacher and peer perceptions of boys classified according to DSM-III criteria for Attention Deficit with Hyperactivity (ADH) and Attention Deficit without Hyperactivity (AD). Teachers completed SNAP checklists (Pelham, Note 1) on all boys in their classrooms (219 boys). Twelve percent fit ADH criteria; less than 5% fit AD criteria. Teacher perceptions were assessed with the Conners Teacher Rating Scale. ADH and AD groups did not differ on the Inattention factor, although the AD group was rated significantly lower than the ADH group on Conduct Problems and Hyperactivity. These profiles were expected on the basis of DSM-III descriptions of ADH and AD; the ADH group seemed to resemble previous research samples of hyperactive children. Classroom peer perceptions, assessed with like-dislike nominations, did not discriminate between diagnostic groups. Both groups were perceived more negatively than the Comparison group, suggesting that both groups are "at risk."

    Research assessing the social skills of children with ADHD has predominantly relied upon North American samples. In addition, most existing work has been conducted using methodology that fails to use a controlled peer stimulus; such methods may be more vulnerable to cultural influence. We examined the social skills of 52 Spanish children (ages 8-12) with and without ADHD using a controlled Chat Room Task, which simulates a virtual social environment where peers' responses are held constant, so that participants' social skills may be assessed. After statistical control of typing and reading comprehension skills, Spanish children with ADHD gave fewer prosocial comments and had greater difficulty remembering central details from the conversation between the peers, relative to comparison children. The virtual Chat Room Task may be useful to assess social skills deficits using a controlled paradigm, resulting in the identification of common social deficiencies cross-culturally.

  14. Peer counseling in a culturally specific adolescent pregnancy prevention program.

    1998-08-01

    This study evaluated the effects of peer counseling in a culturally specific adolescent pregnancy prevention program for African American females. A random pretest and multiple posttest experimental and comparison group design was used to obtain data on a sample of 63 female African American adolescents, ages 12 to 16, who lived in four public housing developments. Descriptive data and tests of significance revealed that none of the participants who received peer counseling became pregnant within three months of the intervention. Findings revealed a statistically significant increase in reproductive and other self-related knowledge topics among the experimental group when comparing pretest and eight-week posttest scores. Most participants had not had sexual intercourse; the average age of sexual onset was 12 years in the experimental group and 11 years in the controls. Designing and implementing culturally specific adolescent pregnancy prevention programs for adolescents younger than age 11 and/or before sexually active seems appropriate.

  15. Acculturative dissonance, ethnic identity, and youth violence.

    Studies suggest that the process of acculturation for immigrant youth, particularly for second-generation youth, is significantly associated with delinquency and violence. This study explored the acculturation-violence link with respect to acculturative dissonance and ethnic identity. The results revealed in a sample of 329 Chinese, Cambodian, Mien/Laotian, and Vietnamese youth that acculturative dissonance was significantly predictive of serious violence, with full mediation through peer delinquency. Ethnic identity was not significantly associated with peer delinquency or serious violence. Although acculturative dissonance and ethnic identity accounted for a small percentage of variance in violence compared with peer delinquency, it cannot be discounted as trivial. Structural equation analyses provided support for both measurement and structural invariance across the four ethnic groups, lending support for cross-cultural comparisons. The results also lend support for the inclusion of cultural factors in youth violence prevention and intervention efforts. 2008 APA

    2009-02-01

    Peer violence, peer sexual harassment and abuse, and staff abuse experienced by boys and girls in juvenile correctional facilities are compared with those experienced by peers in schools in the community. Responses of 360 youths in 20 gender-separated correctional facilities in Israel to a questionnaire tapping these forms of mistreatment were compared with those of 7,012 students in a representative sample of Israeli junior high and high schools. Victimization was reported more frequently by those in correctional facilities than by those in schools. However, some of the more prevalent forms of violence and abuse were reported with equal frequency in both settings, and some more frequently in schools. Despite being victimized more frequently, those in the correctional facilities tended to view their victimization as a significantly less serious problem than those in the schools and to rate the staff as doing a better job of dealing with the problem.

    Rind and Welter (2014) examined first postpubertal coitus using the Kinsey sample, finding that reactions were just as positive, and no more negative, among minors with adults compared to minors with peers and adults with adults. In the present study, we examined first postpubertal male same-sex sexual experiences in the Kinsey same-sex sample (i.e., participants mostly with extensive postpubertal same-sex behavior), comparing reactions across the same age categories. These data were collected between 1938 and 1961 (M year: 1946). Minors under age 18 years with adults (M ages: 14.0 and 30.5, respectively) reacted positively (i.e., enjoyed the experience "much") often (70 %) and emotionally negatively (e.g., fear, disgust, shame, regret) infrequently (16 %). These rates were the same as adults with adults (M ages: 21.2 and 25.9, respectively): 68 and 16 %, respectively. Minors with peers (M ages: 13.3 and 13.8, respectively) reacted positively significantly more often (82 %) and negatively nominally less often (9 %). Minors with adults reacted positively to intercourse (oral, anal) just as often (69 %) as to outercourse (body contact, masturbation, femoral) (72 %) and reacted emotionally negatively significantly less often (9 vs. 25 %, respectively). For younger minors (≤14) with adults aged 5-19 years older, reactions were just as positive (83 %) as for minors with peers within 1 year of age (84 %) and no more emotionally negative (11 vs. 7 %, respectively). Results are discussed in relation to findings regarding first coitus in the Kinsey sample and to the cultural context particular to Kinsey's time.

    To critically review the work sampling technique used in nursing workload research. Work sampling is a technique frequently used by researchers and managers to explore and measure nursing activities. However, work sampling methods used are diverse making comparisons of results between studies difficult. Methodological integrative review. Four electronic databases were systematically searched for peer-reviewed articles published between 2002-2012. Manual scanning of reference lists and Rich Site Summary feeds from contemporary nursing journals were other sources of data. Articles published in the English language between 2002-2012 reporting on research which used work sampling to examine nursing workload. Eighteen articles were reviewed. The review identified that the work sampling technique lacks a standardized approach, which may have an impact on the sharing or comparison of results. Specific areas needing a shared understanding included the training of observers and subjects who self-report, standardization of the techniques used to assess observer inter-rater reliability, sampling methods and reporting of outcomes. Work sampling is a technique that can be used to explore the many facets of nursing work. Standardized reporting measures would enable greater comparison between studies and contribute to knowledge more effectively. Author suggestions for the reporting of results may act as guidelines for researchers considering work sampling as a research method. © 2014 John Wiley & Sons Ltd.

    To compare peer relationships among bereaved siblings and matched classmates, and to examine gender, grade level, and time since death as moderators. Families were recruited from cancer registries at four hospitals 3-12 months after a child's death. Measures of social behavior and peer acceptance were completed by children in the classrooms of 105 bereaved siblings (ages 8-17 years). Teachers also reported on children's social behavior. Three classmates were matched for gender, race, and age to each bereaved sibling to form a comparison group (n = 311). Teachers reported bereaved siblings were more prosocial than comparison classmates. Peers perceived bereaved boys as more sensitive-isolated and victimized, while bereaved siblings in elementary grades were perceived by peers as less prosocial, more sensitive-isolated, less accepted, and as having fewer friends. Peers and teachers viewed bereaved siblings in middle/high school grades as higher on leadership-popularity. Bereaved siblings who were male and in elementary grades were more vulnerable to social difficulties, while those in middle/high school may exhibit some strengths. Ongoing research to inform the development of interventions for bereaved siblings is warranted.

    Little is known about adult women with Attention-Deficit/Hyperactivity Disorder (ADHD), however available evidence suggests that they experience social impairment. Online social networking websites such as Facebook have become endemic outlets through which emerging adults communicate with peers. No study has examined the peer interactions of emerging adults with childhood histories of ADHD in this developmentally relevant online domain. Participants in the current study were an ethnically diverse sample of 228 women, 140 of whom met diagnostic criteria for ADHD in childhood and 88 who composed a matched comparison sample. These women were assessed at three time points spanning 10 years (mean age = 9.6 at Wave 1, 14.1 at Wave 2, 19.6 at Wave 3). After statistical control of demographic covariates and comorbidites, childhood ADHD diagnosis predicted, by emerging adulthood, a greater stated preference for online social communication and a greater tendency to have used online methods to interact with strangers. A childhood diagnosis of ADHD also predicted observations of fewer Facebook friends and less closeness and support from Facebook friends in emerging adulthood. These associations were mediated by a composite of face-to-face peer relationship impairment during childhood and adolescence. Intriguingly, women with persistent diagnoses of ADHD from childhood to emerging adulthood differed from women with consistent comparison status in their online social communication; women with intermittent diagnoses of ADHD had scores intermediate between the other two groups. Results are discussed within the context of understanding the social relationships of women with childhood histories of ADHD. PMID:25894439

    This report details the final results of the EURAMET comparison on regular spectral transmittance carried out between 2006 and 2016. The aim of this comparison was to check the agreement of measurement of the spectral diffuse reflectance among participants, using the measurement geometry of d/0 or 0/d in the wavelength range of 360 nm to 780 nm at 20 nm increment. We used a star type comparison: first the participants sent their samples to the pilot, than the pilot measured all the samples of the participants and sent them back. The participants measured the samples and sent them to the pilot for control measurement. Six standards were used as reference standards in order to maintain the scale during the comparison. These were three samples of BCR-406 opal glasses (BCR 30506; BCR 30303; BCR 30704), an MC20 Russian opal glass (MC 4777) and two samples made of pressed halon (polytetrafluoroethylene) powder (halon 2007A; halon 2007C). These six samples were designated as the Comparison reference standards. The diffuse reflectance was initially measured on the OMH (BFKH) absolute reflectometer. The link to the CCPR-K5 results was BFKH, and the check on BFKH was the PTB results who also participated in the CCPR-K5 comparison. The participants were GUM, INM, LNE, METAS, BFKH, PTB, SP.

    2007-03-01

    Measures of language sample length (in c-units) and morphological, syntactic, and narrative abilities were obtained from oral narrative transcripts of 22 children who stutter and 22 children who do not stutter; participants attended kindergarten, first, and second grades. A two-way MANOVA yielded significant main effects for grade, with significant differences on some measures evidenced between participants in kindergarten and second grades. No significant differences between groups or group-grade interaction effects on the measures were obtained. Grade-wise comparisons (through t-tests) indicated that the performance of children who stutter did not differ significantly from their typically fluent peers on all dependent measures; however, kindergarten children who stutter obtained the most discrepant (lower) scores than their grade-matched fluent peers on the Narrative Scoring Scheme measure, with group differences approaching statistical significance on this measure. The findings suggest that children who do and do not stutter evidence similar expressive language abilities, even as subgroups of children who stutter may lag behind their grade-matched fluent peers in particular language domains.

    Peer education is popular both with governments and with young people. The purpose of this quasi-experimental study was to evaluate the effectiveness of a government-led peer education program on the self-reported sexual health behavior and related psychosocial outcomes of adolescent students in public high schools in the Western Cape of South Africa. Grade 10 students (n = 3934), at 30 public high schools (15 intervention, 15 comparison) were recruited to the study. In the intervention schools, peer educators were recruited and trained to provide information and support to their fellow students. Sexual health behaviors and related psychosocial outcomes of students were measured at baseline and at follow up 18 months later. Comparisons were made between those in the intervention and comparison group schools. We were unable to detect a significant difference in the age of sexual debut, use of condoms at last sex, goal orientation, decision-making or future orientation for students in the intervention group as compared to students in the comparison group. The findings suggest that the peer education program was not effective in reducing the age of sexual debut or condom use. Issues around the implementation of the program suggested that this was sub-optimal. Governments who advocate widespread use of peer education as an approach need to recognise barriers to implementation and ensure ongoing monitoring and evaluation of effectiveness and cost effectiveness.

    This study explores the influence of different social reference points and different comparison group sizes on risky decision-making. Participants were presented with a scenario describing an exam, and presented with the opportunity of making a risky decision in the context of different information provided about the performance of their peers. We found that behavior was influenced, not only by comparison with peers, but also by the size of the comparison group. Specifically, the larger the reference group, the more polarized the behavior it prompted. In situations describing social loss, participants were led to make riskier decisions after comparing themselves against larger groups, while in situations describing social gain, they become more risk averse. These results indicate that decision making is influenced both by social comparison and the number of people making up the social reference group.

  9. Lexical diversity and productivity in Cantonese-speaking children with specific language impairment.

    2000-01-01

    Recent studies of lexical diversity in English-speaking children with specific language impairment (ESLI) have produced conflicting results. Differences between SLI and age-matched (AM) groups on verb types, and overall types have been reported, as have differences between SLI and language-matched (LM) groups on verb types and/or verb tokens, and noun types and noun tokens. At the same time there have been other claims that there is no difference between SLI and LM groups in terms of lexical diversity. This comparison of the lexical diversity of Cantonese-speaking children with SLI (CSLI) and their language-matched peers controlled the length of the samples and the number of tokens as the basis for comparison. There was no difference between the groups in use of verb tokens or types, but there were significant differences in noun tokens and types and 'other' open class tokens and types. Although there was no difference between the groups in the use of a specific grammatical marker (aspect markers), the way in which the CSLI children deployed these markers was severely restricted in comparison with their LM peers. A limited capacity model of language production is invoked to explain the findings.

    The goal of this study was to determine whether differences in incidence of depression and level of well-being are manifested between older women, aged 60 and older, who attend either (a) a peer-run support group, (b) a staff-run support group, or (c) a comparison group (i.e., who do not attend a support group). Thirty-six women participating in peer-run and staff-run support groups and 9 women receiving nongroup support were administered the Geriatric Depression Scale and the Philadelphia Geriatric Center Morale Scale. Separate analyses of variance were employed on each scale to determine the significance of differences in scores according to facilitator type (i.e., peer-run vs. staff-run vs. comparison group). Analysis of scores on the Geriatric Depression Scale indicated significant differences between women in the peer-run groups and women in the comparison group, but no significant differences between women in the peer-run groups and women in the staff-run groups or between women in the staff-run groups and women in the comparison group. Analysis of scores on the Philadelphia Geriatric Center Morale Scale did not indicate any significant differences between women based on facilitator type. Results of this study have implications for those who run face-to-face support groups for older adults, for those who train peer group facilitators, and for community agencies that desire to initiate a support group system for their clientele.

    Prenatal methamphetamine exposure has become an increasingly pervasive concern, especially in rural-based populations and populations of lower socioeconomic status. While research has begun to highlight the effects of prenatal methamphetamine exposure, the long-term impact of this exposure remains an under-investigated topic. This study attempts to investigate the neurocognitive and neurodevelopmental effects of prenatal methamphetamine exposure by comparing the index and full-scale IQ scores on the WISC-IV between a sample of clinically referred children prenatally exposed to methamphetamine (N = 80) and a sample of clinically referred nonexposed children diagnosed with ADHD (N = 44). Children prenatally exposed to methamphetamine showed significantly lower scores on all WISC-IV domains when compared to peers with ADHD. When taking into account polysubstance exposure to alcohol, these differences remained statistically significant, with the exception of the Processing Speed Index (PSI); children reported to have been prenatally exposed to methamphetamine and to alcohol (PME) remained below ADHD peers on all other WISC-IV index scores. Within the prenatally exposed sample, regression analyses indicated that age was a significant negative predictor of PSI scores. Overall findings suggest that prenatal methamphetamine exposure is associated with a notable cognitive impact independent of polysubstance exposure to alcohol, and that the impact of this exposure on processing speed skills may become more pronounced with age.

    Possible interactions among exercise self-identity, social comparison and exercise behaviour were explored in a sample of 417 undergraduate students (mean age = 21.5, SD = 3.0; 73% female). Two models were examined using self-report data; (1) a mediation model which proposed an association between social comparison and exercise behaviour mediated by exercise self-identity and (2) a moderation model proposing an association between exercise behaviour and self-identity moderated by social comparison. Results of the mediation analyses revealed partial mediation of the social comparison--exercise behaviour relationship by self-identity in females. Results of the moderation analyses revealed in males a significant interaction of social comparison with exercise behaviour in the prediction of self-identity - the positive association between exercise behaviour and exercise self-identity showed only significant among male students who believed to exercise equally much or less than peers. Possible explanations and implications for exercise promotion are discussed.

    2014-01-01

    This study examines the effectiveness of a HIV/AIDS peer education program, Teens for AIDS Prevention (TAP) in two cultures. A convenience sample of 287 (American and Nepalese) 9th grade students participated in the study. It was found that HIV/AIDS knowledge scores were significantly higher among American adolescents than their Nepalese counterparts only at pre-intervention. American adolescents had significantly higher self-efficacy scores than Nepalese adolescents both at pre-intervention and post-intervention. Adolescent peer education programs could be used to improve adolescent HIV/AIDS knowledge and self-efficacy for limiting sexual risk behavior; however for the educational programs to be effective, it is pertinent that the program is culturally appropriate to the target population.

    This study aimed to evaluate the Program for the Education and Enrichment of Relational Skills (PEERS: Laugeson et al. in J Autism Dev Disord 39(4):596-606, 2009). PEERS focuses on improving friendship quality and social skills among adolescents with higher-functioning ASD. 58 participants aged 11-16 years-old were randomly assigned to either an immediate treatment or waitlist comparison group. Results revealed, in comparison to the waitlist group, that the experimental treatment group significantly improved their knowledge of PEERS concepts and friendship skills, increased in their amount of get-togethers, and decreased in their levels of social anxiety, core autistic symptoms, and problem behaviors from pre-to post-PEERS. This study provides the first independent replication and extension of the empirically-supported PEERS social skills intervention for adolescents with ASD.

    Children with Attention-Deficit/Hyperactivity Disorder (ADHD) often have poor relationships with peers. However, research on this topic has predominantly focused on boys. This study considered child gender, ADHD status, and dimensionally-assessed conduct problems as predictors of peer relationship difficulties. Participants were 125 children (ages 6–10; 67% male), 63 with clinical diagnoses of ADHD and 62 non-ADHD comparison youth. Conduct problems were reported by teachers and observed in a lab playgroup. Peer relationships were assessed by parent report, teacher report, and peer sociometric nominations in the playgroup. Results suggested that children with ADHD, as well as those with high conduct problems, displayed more impaired peer relationships than did comparison children and those with low conduct problems, but overall there were no gender differences in social functioning. However, statistical interactions appeared such that the negative impact of conduct problems on peer relationships was stronger for girls than for boys. PMID:21916696

    This study explores the influence of different social reference points and different comparison group sizes on risky decision-making. Participants were presented with a scenario describing an exam, and presented with the opportunity of making a risky decision in the context of different information provided about the performance of their peers. We found that behavior was influenced, not only by comparison with peers, but also by the size of the comparison group. Specifically, the larger the reference group, the more polarized the behavior it prompted. In situations describing social loss, participants were led to make riskier decisions after comparing themselves against larger groups, while in situations describing social gain, they become more risk averse. These results indicate that decision making is influenced both by social comparison and the number of people making up the social reference group. PMID:27582723

    This study examined reactions to first postpubertal same-sex sexual experience in the Kinsey female same-sex sample (consisting of females with extensive postpubertal same-sex experience) as a function of participant and partner ages. As such, it complemented the Rind and Welter (2016) study, which examined the same in the Kinsey male same-sex sample. Data were collected by Kinsey interviewers between 1939 and 1961 (M year = 1947). Girls under 18 (M age = 14.9), whose sexual experience was with a woman (M age = 26.3), reacted positively just as often as girls under 18 (M age = 14.1) with peers (M age = 15.0) and women (M age = 22.7) with women (M age = 26.3). The positive-reaction rates were, respectively, 85, 82, and 79 %. In a finer-graded analysis, younger adolescent girls (≤14) (M age = 12.8) with women (M age = 27.4) had a high positive-reaction rate (91 %), a rate reached by no other group. For women (M age = 22.2) with same-aged peers (M age = 22.3), this rate was 86 %. Girls with peers or women had no emotionally negative reactions (e.g., fear, disgust, shame, regret); women with women rarely did. Results contradicted prevailing clinical, legal, and lay beliefs that minor-adult sex is inherently traumatic and would be distinguished as such compared to age-concordant sex. The findings are discussed in terms of the time period in which the sexual experiences occurred.

    Physician performance and peer comparison feedback can affect physician care quality and patient outcomes. This study aimed to understand family physician perspectives of the value of performance feedback in quality improvement (QI) activities. This study analyzed American Board of Family Medicine open-ended survey data collected between 2004 and 2014 from physicians who completed a QI module that provided pre- and post-QI project individual performance data and peer comparisons. Physicians made 3480 comments in response to a question about this performance feedback, which were generally positive in nature (86%). Main themes that emerged were importance of accurate feedback data, enhanced detail in the content of feedback, and ability to customize peer comparison groups to compare performance to peers with similar patient populations or practice characteristics. Meaningful and tailored performance feedback may be an important tool for physicians to improve their care quality and should be considered an integral part of QI project design.

    The number of liver donors has not measurably increased since 2004 and has begun to decrease. Although many waitlisted patients may be suitable candidates to receive a living donor graft, they are often reticent to discuss living donation with close friends and family, partly because of a lack of knowledge about donor health and quality of life outcomes after donation. The objective of this study was to test the effectiveness of an educational intervention that uses testimonials and self-report data from living donors in New York State. The study had an independent sample pretest (n = 437) and posttest (n = 338) design with posttest, between-subjects comparison for intervention exposure. All waitlisted patients at 5 liver transplant centers in New York were provided a peer-based educational brochure and DVD either by mail or at the clinic. The outcome measures were liver candidates' knowledge and self-efficacy to discuss living donation with family and friends. The number and proportion of individuals who presented to centers for living liver donation evaluation were also measured. Liver transplant candidates' self-efficacy to discuss living donation and their knowledge increased from the pretest period to the posttest period. Those exposed to the peer-based intervention reported significantly greater knowledge, a greater likelihood of discussing donation, and increased self-efficacy in comparison with those not exposed to the intervention. The results did not differ by age, length of time on the waiting list, education, or ethnicity. In comparison with the preintervention period, living donation increased 42%, and the number of individuals who presented for donation evaluation increased by 74%.

    Experiences of peer victimization have been repeatedly associated with psychological symptoms and disorders. However, as peer victimization is correlated with child maltreatment occurring within the family, it remains unclear whether the pathological effect of peer victimization is an artifact that can be attributed to previous aversive events. To separate the effects of peer victimization from child maltreatment, we studied both event types as well as psychological symptoms in a mixed clinical sample of ambulant and psychiatric patients (N=168), a self-selected community sample recruited through the internet (N=995), and a student sample (N=272). Hierarchical regression analyses showed that, after controlling for child maltreatment, peer victimization accounted for an incremental proportion of the variance of different symptom dimensions in each sample. These results indicate that peer victimization is an independent predictor of psychopathology.

  6. The interaction between the DRD4 VNTR polymorphism and perceived peer drinking norms in adolescent alcohol use and misuse

    Peer drinking norms are arguably one of the strongest correlates of adolescent drinking. Prospective studies indicate that adolescents tend to select peers based on drinking (peer-selection) and their peers’ drinking is associated with changes in adolescent drinking over time (peer socialization). The present study investigated whether the peer selection and socialization processes in adolescent drinking differed as a function of the DRD4 VNTR genotype in two independent prospective datasets. The first sample was 174 high school students drawn from a 2-wave 6-month prospective study. The second sample was 237 college students drawn from a 3-wave annual prospective study. Multigroup cross-lagged panel analyses of the high school student sample indicated stronger socialization via peer drinking norms among carriers, whereas analyses of the college student sample indicated stronger drinking-based peer selection in the junior year among carriers, compared to non-carriers. Although replication and meta-analytic synthesis are needed, these findings suggest in part genetically determined peer-selection (carriers of the DRD4 7-repeat allele tend to associate with peers who have more favorable attitudes toward drinking and greater alcohol use) and peer socialization (carriers’ subsequent drinking behaviors are more strongly associated with their peer drinking norms) may differ across adolescent developmental stages.

    The aim of this study is to estimate the prevalence of overweight and obesity in a current, nationally representative, random sample of pre-school-aged children in Poland and to compare their overweight and obesity rates with their peers from the US and Norway. The height and weight were measured in a total of 5026 randomly sampled children aged 2-6 years and their Body Mass Index was calculated. The prevalence of overweight including obesity was determined using three definitions, i.e. those formulated by the International Obesity Task Force (IOTF), the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC). The overall prevalence of overweight including obesity in boys was 12.2%, 12.2%, 17.2% and in girls 15.0%, 10.0%, 19.1% according to the IOTF, WHO, CDC definition, respectively, and did not significantly differ in comparison with their US and Norwegian peers. The overall prevalence of obesity in boys was: 4.4%, 4.9%, 8.9% and in girls: 3.8%, 3.4%, 7.6%, according to the IOTF, WHO, CDC definition, respectively. Among Polish girls the obesity rate was higher compared to the female US peers. The obesity rate was higher in Polish boys compared to their Norwegian peers. The estimates of the prevalence of overweight and obesity varied substantially by age group, gender and depending on the definition used. Obesity rates among Polish girls and boys were higher compared to their American and Norwegian peers. The influence of overweight definitions should be taken into account when studying childhood overweight and obesity. Overweight and obesity preventive programs should be implemented at preschool age.

    2015-01-01

    Adolescence and early adulthood are critical periods for the development of mental disorders. Online peer-to-peer communication is popular among young people and may improve mental health by providing social support. Previous systematic reviews have targeted Internet support groups for adults with mental health problems, including depression. However, there have been no systematic reviews examining the effectiveness of online peer-to-peer support in improving the mental health of adolescents and young adults. The aim of this review was to systematically identify available evidence for the effectiveness of online peer-to peer support for young people with mental health problems. The PubMed, PsycInfo, and Cochrane databases were searched using keywords and Medical Subject Headings (MeSH) terms. Retrieved abstracts (n=3934) were double screened and coded. Studies were included if they (1) investigated an online peer-to-peer interaction, (2) the interaction discussed topics related to mental health, (3) the age range of the sample was between 12 to 25 years, and (4) the study evaluated the effectiveness of the peer-to-peer interaction. Six studies satisfied the inclusion criteria for the current review. The studies targeted a range of mental health problems including depression and anxiety (n=2), general psychological problems (n=1), eating disorders (n=1), and substance use (tobacco) (n=2). The majority of studies investigated Internet support groups (n=4), and the remaining studies focused on virtual reality chat sessions (n=2). In almost all studies (n=5), the peer support intervention was moderated by health professionals, researchers or consumers. Studies employed a range of study designs including randomized controlled trials (n=3), pre-post studies (n=2) and one randomized trial. Overall, two of the randomized controlled trials were associated with a significant positive outcome in comparison to the control group at post-intervention. In the remaining four studies, peer-to-peer support was not found to be effective. This systematic review identified an overall lack of high-quality studies examining online peer-to-peer support for young people. Given that peer support is frequently used as an adjunct to Internet interventions for a variety of mental health conditions, there is an urgent need to determine the effectiveness of peer support alone as an active intervention.

    Gender studies (GS) has been challenged on epistemological grounds. Here, we compare samples of peer-reviewed academic journal publications written by GS authors and authors from closely related disciplines in the social sciences. The material consisted of 2805 statements from 36 peer-reviewed journal articles, sampled from the Swedish Gender Studies List, which covers >12,000 publications. Each statement was coded as expressing a lack of any of three aspects of objectivity: Bias, Normativity, or Political activism, or as considering any of four realms of explanation for the behaviours or phenomena under study: Biology/genetics, Individual/group differences, Environment/culture, or Societal institutions. Statements in GS publications did to a greater extent express bias and normativity, but not political activism. They did also to a greater extent consider cultural, environmental, social, and societal realms of explanation, and to a lesser extent biological and individual differences explanations.

    The present research examined the roles of different forms of peer influence, internalization, social comparison, and body dissatisfaction in men's interest in cosmetic surgery. Participants were 204 Italian men (M age  = 34.02, SD = 11.21). Regression analyses showed that appearance conversations with friends and peer attribution were associated with consideration of cosmetic surgery for social reasons, while teasing on muscularity (but not teasing on general body and shape) was linked to interest in cosmetic surgery for intrapersonal motives. Social comparison was significantly and positively associated with men's interest in cosmetic surgery, while internalization was not. Dissatisfaction with body fat was linked to men's consideration of cosmetic surgery for social motivations, while muscularity and height dissatisfaction did not emerge as significant correlates of cosmetic surgery attitudes. These findings highlight the importance of psychosocial factors, such as peer influence, body fat dissatisfaction, and social comparison in men's interest in cosmetic procedures.

    Social comparisons are related to the development of body dissatisfaction among adolescents and adults, yet this relationship remains relatively unexamined among children. This study examines children's peer and media-related social comparisons, and how this impacts on their body image. Children aged 8-10 years completed interviews (17 girls and 19 boys in individual interviews, and 16 girls and 16 boys in focus groups). Analyses revealed that appearance-related comparisons were more common among girls, whereas sports/ability-related comparisons were more common for boys. In addition, boys viewed media comparisons as inspiring, whereas girls reported negative emotions. Implications for future research and prevention programmes are discussed.

    Family factors and emotional functioning can play an important role in the ability of adolescents with juvenile primary fibromyalgia syndrome (JPFS) to cope with their condition and function in their everyday lives. The primary objectives of this study were to determine 1) whether adolescents with JPFS and their caregivers differed from healthy age-matched comparison peers and their caregivers in terms of emotional distress and functional impairment; 2) whether there were any differences in the family environment of adolescents with JPFS compared with healthy comparison peers; and 3) which individual-, caregiver-, and family-level variables were associated with functional impairment in adolescents with JPFS. Participants were 47 adolescents with JPFS recruited from a pediatric rheumatology clinic and 46 comparison peers without chronic illness matched for age, sex, and race. Participants and their caregivers (all mothers) completed a battery of standardized measures administered in their homes. Adolescents with JPFS had greater internalizing and externalizing symptoms than healthy comparison peers. Mothers of adolescents with JPFS reported twice as many pain conditions and significantly greater depressive symptoms than mothers of comparison peers. The JPFS group also had poorer overall family functioning and more conflicted family relationships. In adolescents with JPFS, maternal pain history was associated with significantly higher functional impairment. Increased distress and chronic pain are evident in families of adolescents with JPFS, and family relationships are also impacted. Implications for child functional impairment and the need for inclusion of caregivers in treatment are discussed.

    The ALDH2*2 allele (A-allele) at rs671 is more commonly carried by Asians and is associated with alcohol-related flushing, a strong adverse reaction to alcohol that is protective against drinking. Social factors, such as having friends who binge drink, also contribute to drinking in Asian youth. This study examined the interplay between ALDH2*2, peer drinking, and alcohol consumption in college students. We hypothesized that the relationship between ALDH2*2 and standard grams of ethanol per month would vary based on the level of peer drinking. Subjects (N = 318, 63.25% female) were East Asian college students in the United States who reported drinking alcohol. Data were from the freshman year of a university survey that included a saliva DNA sample. ALDH2*2 status was coded ALDH2*2(+) (A/G and A/A genotypes) and ALDH2*2(-) (G/G genotype). Peer drinking was students' perception of how many of their friends "got drunk". Main effects of ALDH2*2(-) and having more friends who got drunk were associated with greater alcohol consumption. The ALDH2*2 × peer drunkenness interaction showed a stronger positive association with alcohol consumption for ALDH2*2(-) versus ALDH2*2(+) at increasing levels of peer drunkenness. Follow-up comparisons within each peer drunkenness level identified significantly higher alcohol consumption for ALDH2*2(-) compared to ALDH2*2(+) at the all friends got drunk level. There was evidence of a stronger effect for ALDH2*2(-) compared to ALDH2*2(+) with greater alcohol use when students were more exposed to peer drinking. Findings contribute to a growing literature on the interrelationships between genetic influences and more permissive environments for alcohol consumption.

    The developmental consequences in adulthood of growing up with childhood cancer are not well understood. The Course of life questionnaire was developed to assess the attainment of developmental milestones retrospectively and socio-demographic outcomes in young adulthood. The aim of this study was to assess the course of life and socio-demographic outcomes in young adult survivors of childhood cancer. Knowledge about possible gaps in the course of life could enable health care providers to aim for the most favourable course of life. A total of 353 Dutch survivors and a comparison group of 508 peers without a history of cancer, all aged between 18 and 30, filled in the Course of life questionnaire. The course of life of the survivors was found to be hampered. The young adult survivors of childhood cancer in the Netherlands turned out to have achieved fewer milestones than their peers with respect to autonomy development, social development, and psycho-sexual development, or to have achieved the milestones when they were older than their peers. In addition, survivors displayed less risk behaviour than the comparison group. The survivors and the comparison group also differed on some socio-demographic issues. A considerably lower percentage of survivors than peers in the comparison group were married or living together, and/or employed. Their educational level, on the other hand, was as high as that of their peers. Copyright 2004 John Wiley & Sons, Ltd.

  15. Exploration and validation of clusters of physically abused children.

    2008-05-01

    Cluster analysis was used to enhance understanding of heterogeneity in social adjustment of physically abused children. Ninety-eight physically abused children (ages 5-10) were clustered on the basis of social adjustment, as measured by observed behavior with peers on the school playground and by teacher reports of social behavior. Seventy-seven matched nonabused children served as a comparison sample. Clusters were validated on the basis of observed parental sensitivity, parents' self-reported disciplinary tactics, and children's social information processing operations (i.e., generation of solutions to peer relationship problems and attributions of peer intentions in social situations). Three subgroups of physically abused children emerged from the cluster analysis; clusters were labeled Socially Well Adjusted, Hanging in There, and Social Difficulties. Examination of cluster differences on risk and protective factors provided substantial evidence in support of the external validity of the three-cluster solution. Specifically, clusters differed significantly in attributions of peer intent and in parenting (i.e., sensitivity and harshness of parenting). Clusters also differed in the ways in which they were similar to, or different from, the comparison group of nonabused children. Results supported the contention that there were clinically relevant subgroups of physically abused children with potentially unique treatment needs. Findings also pointed to the relevance of social information processing operations and parenting context in understanding diversity among physically abused children. Pending replication, findings provide support for the importance of considering unique treatment of needs among physically abused children. A singular approach to intervention is unlikely to be effective for these children. For example, some physically abused children might need a more intensive focus on development of prosocial skills in relationships with peers while the prosocial skills of other abused children will be developmentally appropriate. In contrast, most physically abused children might benefit from training in social problem-solving skills. Findings also point to the importance of promoting positive parenting practices in addition to reducing harsh discipline of physically abusive parents.

  16. Social Network Influences on Adolescent Substance Use: Disentangling Structural Equivalence from Cohesion

    2012-01-01

    This study investigates two contagion mechanisms of peer influence based on direct communication (cohesion) versus comparison through peers who occupy similar network positions (structural equivalence) in the context of adolescents' drinking alcohol and smoking. To date, the two contagion mechanisms have been considered observationally inseparable, but this study attempts to disentangle structural equivalence from cohesion as a contagion mechanism by examining the extent to which the transmission of drinking and smoking behaviors attenuates as a function of social distance (i.e., from immediate friends to indirectly connected peers). Using the U.S. Add Health data consisting of a nationally representative sample of American adolescents (Grades 7-12), this study measured peer risk-taking up to four steps away from the adolescent (friends of friends of friends of friends) using a network exposure model. Peer influence was tested using a logistic regression model of alcohol drinking and cigarette smoking. Results indicate that influence based on structural equivalence tended to be stronger than influence based on cohesion in general, and that the magnitude of the effect decreased up to three steps away from the adolescent (friends of friends of friends). Further analysis indicated that structural equivalence acted as a mechanism of contagion for drinking and cohesion acted as one for smoking. These results indicate that the two transmission mechanisms with differing network proximities can differentially affect drinking and smoking behaviors in American adolescents. PMID:22475405

    To examine interpersonal relationships involving peers and teachers and perceptions about school environment among middle school students with asthma in comparison to their healthy counterparts. The study also assesses asthma prevalence in a large sample of middle school students representing different geographic locations. Cross-sectional data were collected from 1059 middle school students in grades 6-8 enrolled in schools in a northeastern region of the United States. Students reported their chronic health conditions including asthma and completed questionnaires measuring perceptions about their relationships with peers and teachers as well as school environment. Analyses of covariance (ANCOVAs) were used to compare students with asthma and their healthy counterparts in the study variables. Asthma was reported by 16.5% of the sample (n = 169). The rate was higher among minority students (23%) than their white counterparts (15%). Greater proportion of urban students (28%) reported asthma than rural (18%) and suburban (14%) students. Students with asthma reported significantly poorer relationships with peers (B = -1.74, p <.001) and teachers (B = -1.41, p =.009), and their perceptions about overall school environment (B = -1.30, p =.009) were also lower than their healthy counterparts. Race showed no significant effects on school factors. Overall asthma prevalence was substantially higher than the national average of adolescent asthma, particularly those residing in the urban area. Poor perceptions of interpersonal relationships with peers and teachers among students with asthma may indicate compromised quality of life. Suboptimal interpersonal relationships and school environment need to be identified and adequately addressed, given their implications for asthma management at the school setting among middle school students.

    This study aims to describe psychological problems, self-esteem difficulties and body dissatisfaction in a sample of adolescents with acquired brain lesions and to compare them with an age- and gender-matched control group. In an experimental design, the psychological profile of 26 adolescents with brain lesions of traumatic or vascular aetiology, aged 12-18 years, was compared with that of 18 typically-developing subjects. Moreover, within the clinical group, patients with TBI were compared with patients with vascular lesions. The psychological and adaptive profile of the adolescents was assessed by a specific protocol, including CBCL, VABS, RSES, EDI-2 and BES. Adolescents with brain lesions showed more marked psychological problems than their healthy peers; they also presented with a greater impairment of adaptive skills and a lower self-esteem. No significant differences were found between patients with traumatic lesions and patients with vascular lesions. Adolescents with acquired brain lesions were at higher risk to develop psychological and behavioural difficulties. Furthermore, in the clinical sample, some variables such as the long hospitalization and isolation from family and peers were associated to a greater psychological burden than the aetiology of the brain damage.

  20. Elucidating the mechanisms linking early pubertal timing, sexual activity, and substance use for maltreated versus nonmaltreated adolescents

    Purpose To test models linking pubertal timing, peer substance use, sexual behavior, and substance use for maltreated versus comparison adolescents. Three theoretical mechanisms were tested: 1) peer influence links early pubertal timing to later sexual behavior and substance use, 2) early maturers engage in substance use on their own and then select substance-using friends, or 3) early maturers initiate sexual behaviors which leads them to substance-using peers. Methods The data came from a longitudinal study of the effects of child maltreatment on adolescent development (303 maltreated and 151 comparison adolescents; age: 9–13 years at initial wave). Multiple-group structural equation models tested the hypotheses across three timepoints including variables of pubertal timing, perception of peer substance use, sexual behavior, and self-reported substance use. Results Early pubertal timing was associated with substance-using peers only for maltreated adolescents, indicating the mediation path from early pubertal timing through substance-using peers to subsequent adolescent substance use and sexual behavior only holds for maltreated adolescents. Mediation via sexual behavior was significant for both maltreated and comparison adolescents. This indicates that sexual behavior may be a more universal mechanism linking early maturation with risky friends regardless of adverse life experiences. Conclusions The findings are a step toward elucidating the developmental pathways from early puberty to risk behavior and identifying early experiences that may alter mediation effects.

    BACKGROUND A cancer diagnosis during adolescence or young adulthood may negatively influence social well-being. The existing literature concerning the social well-being of adolescents and young adults (AYAs) with cancer was reviewed to identify gaps in current research and highlight priority areas for future research. METHODS A systematic review of the scientific literature published in English from 2000 through 2014 was performed. Eligible studies included patients and survivors diagnosed between the ages of 15 to 39 years that reported on social well-being domains in the City of Hope Cancer Survivor Quality of Life Model. Each article was reviewed for relevance using a standardized template. A total of 253 potential articles were identified. After exclusions, a final sample of 26 articles identified domains of social well-being that are believed to be understudied among AYAs with cancer: 1) educational attainment, employment, and financial burden; 2) social relationships; and 3) supportive care. Articles were read in their entirety, single coded, and summarized according to domain. RESULTS AYAs with cancer report difficulties related to employment, educational attainment, and financial stability. They also report problems with the maintenance and development of peer and family relationships, intimate and marital relationships, and peer support. Supportive services are desired among AYAs. Few studies have reported results in reference to comparison samples or by cancer subtypes. CONCLUSIONS Future research studies on AYAs with cancer should prioritize the inclusion of underserved AYA populations, more heterogeneous cancer samples, and comparison groups to inform the development of supportive services. Priority areas for potential intervention include education and employment reintegration, and social support networks. PMID:26848713

    The Tripartite Influence Model posits that parents, peers and media influences mediated by internalization and appearance social comparison are predictors of body dissatisfaction, a key risk factor for eating disorders. However, the Tripartite Influence Model has not been tested in Brazil where the people are known to have high levels of body image and appearance concerns. This study aimed to test an adapted Tripartite Influence Model of body dissatisfaction and disordered eating behaviors among Brazilian women. A sample of 741 undergraduate students (M age  = 23.55 years, SD = 4.09) completed measures of sociocultural influences, internalization of body ideal, social appearance comparison, body dissatisfaction, muscularity dissatisfaction, disordered eating and body change behaviors. Structural equation modeling analyses indicated that the proposed etiological model for Brazilian women has good fit indexes (χ 2 (2064) = 6793.232; p = 0.0001; χ 2 /gl = 3.29; CFI = 0.82; PCFI = 0.79; RMSEA = 0.056 [IC90% = 0.053-0.057]). Parent and media influences were related with both internalization and social comparison, while peer influence with social comparison. A full mediation model was found, with both internalization and social comparison contributing to body dissatisfaction. Finally, body dissatisfaction was associated with disordered eating behaviors. The findings inform the importance of considering cultural aspects that influence body image and eating behaviors, and highlight the validity of the proposed etiological model for Brazilian women, that can be used for research and clinical purposes.

    A key comparison on the determination of (pp'-dichlorodiphenyl) trichloroethane (pp'-DDT) in a fish oil matrix has been successfully completed. Nine NMIs participated in this key comparison and used the technique of isotope dilution gas-chromatography mass spectrometry (ID/GC/MS) for the determinations. Two samples (A and B) of fish oil were distributed to participants, each gravimetrically spiked with pp'-DDT. The KCRV for Sample A is 0.0743 +/- 0.0020 µg g-1 and that of Sample B is 0.1655 +/- 0.0014 µg g-1 of pp'-DDT in fish oil. The results for Sample A showed a RSD of 3.5%, the RSD for Sample B was within 1%. These results were an improvement over those of the corresponding pilot study (CCQM-P21), where at a mass fraction of pp'-DDT in fish oil of 0.311 µg g-1 the RSD was 2.6%. The compound pp'-DDT is a typical organochlorine pesticide and this key comparison has shown that NMIs have the ability to measure such compounds at levels typically found in the environment. The compound (pp'-dichlorodiphenyl) dichloroethylene (pp'-DDE), a metabolite of pp'-DDT, was the subject of a previous key comparison (CCQM-K5). The compound pp'-DDT is technically more challenging than that of pp'-DDE since it can decompose during the measurement procedure. Consequently the success of this key comparison, combined with that of CCQM-K5 demonstrates a broad measurement capability by NMIs for organochlorine compounds in the environment. Main text.

    Publicly reported performance data for hospitals and nursing homes are becoming ubiquitous. For such comparisons to be fair, facilities must be compared with their peers. To adapt a previously published methodology for developing hospital peer groupings so that it is applicable to nursing homes and to explore the characteristics of "nearest-neighbor" peer groupings. Analysis of Department of Veterans Affairs administrative databases and nursing home facility characteristics. The nearest-neighbor methodology for developing peer groupings involves calculating the Euclidean distance between facilities based on facility characteristics. We describe our steps in selection of facility characteristics, describe the characteristics of nearest-neighbor peer groups, and compare them with peer groups derived through classical cluster analysis. The facility characteristics most pertinent to nursing home groupings were found to be different from those that were most relevant for hospitals. Unlike classical cluster groups, nearest neighbor groups are not mutually exclusive, and the nearest-neighbor methodology resulted in nursing home peer groupings that were substantially less diffuse than nursing home peer groups created using traditional cluster analysis. It is essential that healthcare policy makers and administrators have a means of fairly grouping facilities for the purposes of quality, cost, or efficiency comparisons. In this research, we show that a previously published methodology can be successfully applied to a nursing home setting. The same approach could be applied in other clinical settings such as primary care.

    This document describes the result of a key comparison for propane in nitrogen. The nominal amount-of-substance fraction of propane is 1000 μmol/mol. The comparison aimed to assess the measurement capability of participants in gas analysis. Nine NMIs or DIs participated in the comparison. CERI participated in a key comparison CCQM-K111—propane in nitrogen, and coordinated this key comparison. Therefore, every participants' results of this comparison are linking to the CCQM-K111. Gravimetric values of the samples were used as key comparison reference values (KCRVs). Measured values of eight participants were within +/- 0.25 % of the KCRVs. Many participants reported purity or impurity analysis of materials. These results are also able to assess the participants' capability of the analysis.

    Objectives. To investigate self-reported health-related quality of life (HrQoL) in children and adolescents with chronic medical conditions compared with siblings/peers. Methods. Group 1 (6 treatment centers) consisted of 74 children/adolescents aged 8–16 years with hereditary bleeding disorders (HBD), 12 siblings, and 34 peers. Group 2 (one treatment center) consisted of 70 children/adolescents with stroke/transient ischemic attack, 14 siblings, and 72 peers. HrQoL was assessed with the “revised KINDer Lebensqualitätsfragebogen” (KINDL-R) questionnaire. Multivariate analyses within groups were done by one-way ANOVA and post hoc pairwise single comparisons by Student's t-tests. Adjusted pairwise comparisons were done by hierarchical linear regressions with individuals nested within treatment centers (group 1) and by linear regressions (group 2), respectively. Results. No differences were found in multivariate analyses of self-reported HrQoL in group 1, while in group 2 differences occurred in overall wellbeing and all subdimensions. These differences were due to differences between patients and peers. After adjusting for age, gender, number of siblings, and treatment center these differences persisted regarding self-worth (p = .0040) and friend-related wellbeing (p < .001). Conclusions. In children with HBD, HrQoL was comparable to siblings and peers. In children with stroke/TIA HrQoL was comparable to siblings while peers, independently of relevant confounder, showed better self-worth and friend-related wellbeing. PMID:27294108

    2015-01-01

    This study seeks to analyse the relationship between behaviour problems in deaf children and their auditory and communication development subsequent to cochlear implantation and to examine the incidence of these problems in comparison to their hearing peers. This study uses an ex post facto prospective design with a sample of 208 Spanish children, of whom 104 were deaf subjects with cochlear implants. The first objective assesses the relationships between behaviour problems, auditory integration, and social and communication skills in the group of deaf children. The second compares the frequency and intensity of behaviour problems of the group of deaf children with their hearing peers. The correlation analysis showed a significant association between the internal index of behaviour problems and auditory integration and communication skills, such that deaf children with greater auditory and communication development had no behaviour problems. When comparing behaviour problems in deaf children versus their hearing peers, behavioural disturbances are significantly more frequent in the former. According to these findings, cochlear implants may not guarantee adequate auditory and communicative development that would normalise the behaviour of deaf children.

    The aim of this study was to compare the learning effectiveness of peer tutored problem-based learning and conventional teaching of nursing ethics in Taiwan. The study adopted an experimental design. The peer tutored problem-based learning method was applied to an experimental group and the conventional teaching method to a control group. The study sample consisted of 142 senior nursing students who were randomly assigned to the two groups. All the students were tested for their nursing ethical discrimination ability both before and after the educational intervention. A learning satisfaction survey was also administered to both groups at the end of each course. After the intervention, both groups showed a significant increase in ethical discrimination ability. There was a statistically significant difference between the ethical discrimination scores of the two groups (P < 0.05), with the experimental group on average scoring higher than the control group. There were significant differences in satisfaction with self-motivated learning and critical thinking between the groups. Peer tutored problem-based learning and lecture-type conventional teaching were both effective for nursing ethics education, but problem-based learning was shown to be more effective. Peer tutored problem-based learning has the potential to enhance the efficacy of teaching nursing ethics in situations in which there are personnel and resource constraints.

    Past studies have shown that jealousy peaks in adolescence. However, little is known about how and when adolescents experience jealousy in their daily lives. The current study aimed to examine the relation between state jealousy, the more general propensity to feel jealous, the interpersonal contexts in which jealousy arises, and different forms of social comparison. The impact of jealousy on perceptions of well-being was also explored. We used an experience sampling method during two weekends with 68 adolescents (M age  = 13.94; 64.70% girls). Jealousy was common: On average, 90% of our sample experienced jealousy in 20% of the assessments. Adolescents reported more jealousy with peers than with family. Additionally, they experienced more jealousy when in online contexts than when in face-to-face peer contexts. The normative nature of jealousy, its developmental function and relation with well-being, and implications for understanding jealousy triggered in (highly social) online contexts are discussed.

    The purpose of this randomized control group study was to examine the effects of a peer network intervention that included peer mediation and direct instruction for Kindergarten and First-grade children with Autism Spectrum Disorders (ASD). Trained school staff members provided direct instruction for 56 children in the intervention group, and 39 children participated in a comparison group. Results showed children in the intervention group displayed significantly more initiations to peers than did the comparison group during non-treatment social probes and generalization probes. Treatment session data showed significant growth for total communications over baseline levels. Children in treatment also showed more growth in language and adaptive communication. Finally, teachers’ ratings of prosocial skills revealed significantly greater improvements for the intervention group. PMID:25510450

    To test models linking pubertal timing, peer substance use, sexual behavior, and substance use for maltreated versus comparison adolescents. Three theoretical mechanisms were tested: (1) peer influence links early pubertal timing to later sexual behavior and substance use; (2) early maturers engage in substance use on their own and then select substance-using friends; or (3) early maturers initiate sexual behaviors which lead them to substance-using peers. The data came from a longitudinal study of the effects of child maltreatment on adolescent development (303 maltreated and 151 comparison adolescents; age, 9-13 years at initial wave). Multiple-group structural equation models tested the hypotheses across three time points including variables of pubertal timing, perception of peer substance use, sexual behavior, and self-reported substance use. Early pubertal timing was associated with substance-using peers only for maltreated adolescents, indicating the mediation path from early pubertal timing through substance-using peers to subsequent adolescent substance use and sexual behavior only holds for maltreated adolescents. Mediation via sexual behavior was significant for both maltreated and comparison adolescents. This indicates that sexual behavior may be a more universal mechanism linking early maturation with risky friends regardless of adverse life experiences.

    Clinicians, scientists, and policy makers are increasingly taking interest in the long-term outcomes of early intervention programs undertaken during the 1960s and 1970s, which were intended to improve young children's health and educational prospects. The Brookline Early Education Project (BEEP) was an innovative, community-based program that provided health and developmental services for children and their families from 3 months before birth until entry into kindergarten. It was open to all families in the town of Brookline and to families from neighboring Boston, to include a mixture of families from suburban and urban communities. The goal of the project, which was administered by the Brookline Public Schools, was to ensure that children would enter kindergarten healthy and ready to learn. Outcome studies of BEEP and comparison children during kindergarten and second grade demonstrated the program's effectiveness during the early school years. The goal of this follow-up study was to test the hypotheses that BEEP participants, in comparison with their peers, would have higher levels of educational attainment, higher incomes, and more positive health behaviors, mental health, and health efficacy during the young adult period. Participants were young adults who were enrolled in the BEEP project from 1973 to 1978. Comparison subjects were young adults in Boston and Brookline who did not participate in BEEP but were matched to the BEEP group with respect to age, ethnicity, mother's educational level, and neighborhood (during youth). A total of 169 children were enrolled originally in BEEP and monitored through second grade. The follow-up sample included a total of 120 young adults who had participated in BEEP as children. The sample differed from the original BEEP sample in having a slightly larger proportion of college-educated mothers and a slightly smaller proportion of urban families but otherwise resembled the original BEEP sample. The demographic features of the BEEP and comparison samples were similar. The young adults were asked to complete a survey that focused on the major domains of educational/functional outcomes and health/well-being. The study used a quasi-experimental causal-comparative design involving quantitative analyses of differences between the BEEP program and comparison groups, stratified according to community. Hypotheses were tested with analysis of variance and multivariate analysis of variance techniques. Analyses of the hypotheses included the main effects of group (BEEP versus comparison sample) and community (suburban versus urban location), as well as their interaction. Young adults from the suburban community had higher levels of educational attainment than did those in the urban group, with little difference between the suburban BEEP and comparison groups. In the urban group, participation in the BEEP program was associated with completing >1 additional year of schooling. Fewer BEEP young adults reported having a low income (less than 20000 dollars); the income differences were accounted for largely by the urban participants. The percentage of subjects with private health insurance was significantly lower in the urban group overall, but the BEEP urban group had higher rates of private insurance than did the comparison group. More than 80% of both suburban samples reported being in very good or excellent health; the 2 urban groups had significantly lower ratings, with 64% of the BEEP group and only 41.67% of the comparison group reaching this standard. Overall, suburban participants reported more positive health behaviors, more perceived competence, and less depression. Among the urban samples, however, participation in BEEP was associated with higher levels of health efficacy, more positive health behaviors, and less depression than their peers. No previous study has focused as extensively on health-related outcomes of early education programs. BEEP participants living in urban communities had advantages over their peers in educational attainment, income, health, and well-being. The educational advantages found for BEEP participants in the early years of schooling included executive skills such as planning, organizing, and completing school-related tasks. It is likely that these early advantages in executive function extended beyond education-related tasks to other activities as participants became responsible for their own lives. The long-term benefits revealed in this study are consistent with the findings of previous long-term studies that indicated that participants in high-quality intervention programs are less likely to cost taxpayers money for health, educational, and public assistance services. The BEEP program appears to have somewhat blunted differences between the urban and suburban groups. The results of this study add to the growing body of findings that indicate that long-term benefits occur as the result of well-designed, intensive, comprehensive early education. The health benefits add a unique and important extension to the findings of other studies.

    Few studies have examined the effects of parental MS on children, and those that have suffered from numerous methodological weaknesses, some of which are addressed in this study. This study investigated the effects of parental MS on children by comparing youth of a parent with MS to youth who have no family member with a serious health condition on adjustment outcomes, caregiving, attachment and family functioning. A questionnaire survey methodology was used. Measures included youth somatisation, health, pro-social behaviour, behavioural-social difficulties, caregiving, attachment and family functioning. A total of 126 youth of a parent with MS were recruited from MS Societies in Australia and, were matched one-to-one with youth who had no family member with a health condition drawn from a large community sample. Comparisons showed that youth of a parent with MS did not differ on any of the outcomes except for peer relationship problems: adolescent youth of a parent with MS reported lower peer relationship problems than control adolescents. Overall, results did not support prior research findings suggesting adverse impacts of parental MS on youth.

    2010-01-01

    Background Preclinical and other research suggest that youth with prenatal cocaine exposure (PCE) may be at high risk for cocaine use due to both altered brain development and exposure to unhealthy environments. Methods Participants are early adolescents who were prospectively enrolled in a longitudinal study of PCE prior to or at birth. Hair samples were collected from the youth at ages 10½ and 12½ (N=263). Samples were analyzed for cocaine and its metabolites using ELISA screening with gas chromatography/mass spectroscopy (GC/MS) confirmation of positive samples. Statistical analyses included comparisons between the hair-positive and hair-negative groups on risk and protective factors chosen a priori as well as hierarchical logistical regression analyses to predict membership in the hair-positive group. Results Hair samples were positive for cocaine use for 14% (n=36) of the tested cohort. Exactly half of the hair-positive preteens had a history of PCE. Group comparisons revealed that hair-negative youth had significantly higher IQ scores at age 10½; the hair-positive youth had greater availability of cigarettes, alcohol, and other drugs in the home; caregivers with more alcohol problems and depressive symptoms; less nurturing home environments; and less positive attachment to their primary caregivers and peers. The caregivers of the hair-positive preteens reported that the youth displayed more externalizing and social problems, and the hair-positive youth endorsed more experimentation with cigarettes, alcohol, and/or other drugs. Mental health problems, peer drug use, exposure to violence, and neighborhood characteristics did not differ between the groups. Regression analyses showed that the availability of drugs in the home had the greatest predictive value for hair-positive group membership while higher IQ, more nurturing home environments, and positive attachment to caregivers or peers exerted some protective effect. Conclusion The results do not support a direct relationship between PCE and early adolescent experimentation with cocaine. Proximal risk and protective factors—those associated with the home environment and preteens' caregivers—were more closely related to early cocaine use than more distal factors such as neighborhood characteristics. Consistent with theories of adolescent problem behavior, the data demonstrate the complexity of predicting pre-adolescent drug use and identify a number of individual and contextual factors that could serve as important foci for intervention.

    Purpose The purpose of this study was to explore the experiences and impact of peer-to-peer shadowing as a technique to develop nurse middle managers' clinical leadership practices. Design/methodology/approach A qualitative descriptive study was conducted to gain insight into the experiences of nurse middle managers using semi-structured interviews. Data were analysed into codes using constant comparison and similar codes were grouped under sub-themes and then into four broader themes. Findings Peer-to-peer shadowing facilitates collective reflection-in-action and enhances an "investigate stance" while acting. Nurse middle managers begin to curb the caring disposition that unreflectively urges them to act, to answer the call for help in the here and now, focus on ad hoc "doings", and make quick judgements. Seeing a shadowee act produces, via a process of social comparison, a behavioural repertoire of postponing reactions and refraining from judging. Balancing the act of stepping in and doing something or just observing as well as giving or withholding feedback are important practices that are difficult to develop. Originality/value Peer-to-peer shadowing facilitates curbing the caring disposition, which is essential for clinical leadership development through unlocking a behavioural repertoire that is not easy to reveal because it is, unreflectively, closely knit to the professional background of the nurse managers. Unlike most leadership development programmes, that are quite introspective and detached from context, peer-to-peer shadowing does have the potential to promote collective learning while acting, which is an important process.

    Chronic parental maltreatment has been associated with lower levels of interpersonal trust, and depriving environments have been shown to predict shortsighted, risk-averse decision-making. The present study examined whether a circumscribed period of adverse care occurring only early in life was associated with biases in trust behavior. Fifty-three post-institutionalized (PI) youth, adopted internationally on average by one year of age, and 33 never-institutionalized, non-adopted youth (M age = 12.9 years) played a trust game. Participants decided whether or not to share coins with a different anonymous peer in each trial with the potential to receive a larger number of coins in return. Trials were presented in blocks that varied in the degree to which the peers behaved in a trustworthy (reciprocal) or untrustworthy (non-reciprocal) manner. A comparison condition consisted of a computerized lottery with the same choices and probabilistic risk as the peer trials. Non-adopted comparison youth showed a tendency to share more with peers than to invest in the lottery and tended to maintain their level of sharing across trials despite experiencing trials in which peers failed to reciprocate. In contrast, PI children, particularly those who were adopted over a year of age, shared less with peers than they invested in the lottery and quickly adapted their sharing behavior to peers' responses. These results suggest that PI youth were more mistrusting, more sensitive to both defection and reciprocation, and potentially more accurate in their trusting decisions than comparison youth. Results support the presence of a sensitive period for the development of trust in others, whereby conditions early in life may set long-term biases in decision-making. PMID:27089448

    2013-01-01

    The CCPR K5 key comparison on spectral diffuse reflectance was carried out in the framework of the CIPM Mutual Recognition Arrangement, by 13 national metrology institutes (MMIs) as participants. The participants were CSIR-NML (South Africa), HUT (Finland), IFA-CSIC (Spain), KRISS (Republic of Korea), MSL (New Zealand), NIM (China), NIST (United States of America), NMIJ (Japan), NPL (United Kingdom), NRC (Canada), OMH (Hungary), PTB (Germany) and VNIIOFI (Russia Federation). NIST (USA) piloted the comparison. The aim of this comparison was to check the agreement of measurement of the spectral diffuse reflectance among participants, using the measurement geometry of d/0 or 0/d in the wavelength range of 360 nm to 820 nm at 20 nm increment. The comparison was a star type comparison with the samples provided by the pilot laboratory and with the measurement sequence: Pilot-Participant-Pilot. Spectralon and matte white ceramic tiles were used as the transfer standards. Each participant received three of each type of sample and at least one sample of each type was measured three times on three separate days, and the other two samples were measured once. The report presents the description of the measurement facilities, procedures and uncertainties of all the participants as well as the results of the comparison. Measurement results from the participants and their associated uncertainties were analyzed in accordance with the Guidelines for CCPR Key Comparison Report Preparation, using weighted mean with cut-off. For the calculation of the Key Comparison Reference Value (KCRV), as agreed by the participants, the data of both samples were used for the 460 nm to 820 nm region and only the data of the Spectralon samples were used in the spectral region of 360 nm to 440 nm. The unilateral degrees of equivalence (DoE) calculated for each participant are mostly consistent within the uncertainty (k = 2) of the DoE. This international comparison of spectral diffuse reflectance shows overall good agreement among all participants. Main text. To reach the main text of this paper, click on Final Report.

    Developmental trajectories in delinquency through adolescence were studied along with family and peer relationship problems. Drawing from eight waves of data over seven years, we conducted trajectory analyses with a sample of 746 students (402 girls; 344 boys). Analyzing girls and boys together, a five-class model emerged: 60% of the adolescents rarely reported delinquency; 27.7% reported low initial levels with moderate levels of delinquency over time; 6% in the late onset group reported initially low and rising levels of delinquency; 5% in the early onset group reported moderate initial levels which increased and then decreased in later adolescence. A small group of only boys (1.3%) labeled chronic reported high initial levels of delinquency that increased over time. Group comparisons revealed problems in internalizing, parent and peer relationship problems. The findings provide direction for early identification and interventions to curtail the development of delinquency.

    The study aimed to examine the influence of media and peers on attitudes towards cosmetic surgery using a sociocultural framework. A sample of 351 Australian women aged 18-69 years completed measures of media exposure, friend conversations, internalisation of appearance ideals, appearance comparison, body dissatisfaction, and attitudes towards cosmetic surgery. Correlational analysis showed that almost all media and friend variables were significantly correlated with positive attitudes towards cosmetic surgery. A structural equation model based on the sociocultural model showed a good level of fit to the data. The effects of media exposure and friend conversations on body dissatisfaction and attitudes towards cosmetic surgery were mediated by internalisation. We concluded that media exposure and friend conversations affected attitudes towards cosmetic surgery both directly and indirectly. Our results contribute to the understanding of the sociocultural mechanisms underlying women's motivations for cosmetic surgery. Copyright © 2014 Elsevier Ltd. All rights reserved.

  10. The Romantic Relationships of Adolescents With ADHD.

    This study compared the romantic relationships of adolescents with and without ADHD with regard to romantic involvement, relationship content, and relationship quality. A community sample of 58 participants (30 ADHD, 28 Comparison), ages 13 to 18, completed questionnaires assessing various features of romantic relationships. Adolescents with ADHD reported having more romantic partners than their typically developing (TD) peers. Females with ADHD were found to have shorter romantic relationships than TD adolescents while males with ADHD reported their age of first intercourse to be nearly 2 years sooner than TD peers. Irrespective of gender, adolescents with ADHD had nearly double the number of lifetime sexual partners. However, the romantic relationships of adolescents with and without ADHD did not differ on levels of aggression or relationship quality. Given the outcomes associated with poor-quality romantic relationships, comprehensive assessments of adolescents with ADHD should include queries into their romantic relationships.

    This study investigates the impact of collaborative reflections on teachers' inquiry teaching practices and identifies supportive actions relating to their professional development. Three science teachers in the same elementary school worked as a cooperative and collaborative group. They attended workshops and worked collaboratively through observing colleagues' teaching practices and discussing with university professors about their own inquiry teaching. The pre- and post-treatment classroom observations and comparisons of their teaching reveal that the three teachers were more focussed on asking inquiry-oriented questions in the post-treatment teaching. With additional qualitative data analysis, this study identified supportive resources of professional development. Workshop training sessions and sample unit served as the initiative agent in the beginning stage. Discussions with peers and reflective observation of peer teaching acted as a facilitative agent. Finally, student responses and researchers' on-site visit comments worked as a catalytic agent for their professional development.

    This paper examines peer recruitment dynamics through respondent driven sampling (RDS) with a sample of injection drug users in Hartford, CT to understand the strategies participants use to recruit peers into a study and the extent to which these strategies may introduce risks above the ethical limit despite safeguards in RDS. Out of 526 injection drug users who participated in a mixed-method RDS methodology evaluation study, a nested sample of 61 participants completed an in-depth semi-structured interview at a 2-month follow-up to explore their experiences with the recruitment process. Findings revealed that participants used a variety of strategies to recruit peers, ranging from one-time interactions to more persistent strategies to encourage participation (e.g., selecting peers that can easily be found and contacted later, following up with peers to remind them of their appointment, accompanying peers to the study site, etc.). Some participants described the more persistent strategies as helpful, while some others experienced these strategies as minor peer pressure, creating a feeling of obligation to participate. Narratives revealed that overall, the probability of experiencing study-related risks remains relatively low for most participants; however, a disconcerting finding was that higher study-related risks (e.g., relationship conflict, loss of relationship, physical fights, violence) were seen for recruits who participated but switched coupons or for recruits who decided not to participate in the study and did not return the coupon to the recruiter. Findings indicate that peer recruitment practices in RDS generally pose minimal risk, but that peer recruitment may occasionally exceed the ethical limit, and that enhanced safeguards for studies using peer recruitment methods are recommended. Suggestions for possible enhancements are described. Copyright © 2015 Elsevier B.V. All rights reserved.

    The EUROMET project 696, a trilateral comparison between PTB, Germany, LNE, France and VNIIFTRI, Russia was performed in order to demonstrate and document the capability of the participants to measure the pH of a phthalate buffer by the primary measurement procedure for pH. Good agreement of the reported results was observed. The sample was very similar to the one used in the comparison CCQM-K17. PTB acts as pilot laboratory in CCQM-K17 and in EUROMET 696. This comparison allows one to link the results obtained by LNE to the CCQM-K17 key comparison through the degree of equivalence of PTB. On the other hand, the discrepancy between measured pH values at the VNIIFTRI and PTB for the same type of buffer solution decreased, as compared with a bilateral comparison in 1997. Main text.

    Using a genetically informed design, this study examined the additive and interactive effects of genetic risk, personal peer victimization experiences, and peer victimization experienced by others on children's aggression and depression symptoms. Of major interest was whether these effects varied depending on whether or not the victimized others were children's close friends. The sample comprised 197 monozygotic and same-sex dizygotic twin pairs reared together (95 female pairs) assessed in Grade 4. Each twin's victimization experiences and victimization experienced by his or her friends and other classmates were measured using individuals' reports about their own levels of peer victimization. Aggression was assessed using peer nominations, and depression was measured using self-reports. Indicative of a possible social-learning mechanism or the emotional contagion of anger, multilevel regressions showed that personal victimization experiences were related to especially high levels of aggression when close friends where also highly victimized, albeit only in boys. Moreover, in line with social comparison theory, the effect of frequent personal victimization experiences on depressive feelings was much weaker when close friends were also highly victimized than when close friends were not or were only rarely victimized. Finally, a high level of peer victimization experienced by other classmates was related to a lower level of aggression in girls and boys, possibly because of a heightened sense of threat in classrooms where many suffer attacks from bullies. All of these results were independent of children's genetic risk for aggression or depression. Theoretical and practical implications are discussed. (c) 2013 APA, all rights reserved.

    The CCQM-K69 key comparison of testosterone glucuronide in human urine was organized under the auspices of the CCQM Organic Analysis Working Group (OAWG). The National Measurement Institute Australia (NMIA) acted as the coordinating laboratory for the comparison. The samples distributed for the key comparison were prepared at NMIA with funding from the World Anti-Doping Agency (WADA). WADA granted the approval for this material to be used for the intercomparison provided the distribution and handling of the material were strictly controlled. Three national metrology institutes (NMIs)/designated institutes (DIs) developed reference methods and submitted data for the key comparison along with two other laboratories who participated in the parallel pilot study. A good selection of analytical methods and sample workup procedures was displayed in the results submitted considering the complexities of the matrix involved. The comparability of measurement results was successfully demonstrated by the participating NMIs. Only the key comparison data were used to estimate the key comparison reference value (KCRV), using the arithmetic mean approach. The reported expanded uncertainties for results ranged from 3.7% to 6.7% at the 95% level of confidence and all results agreed within the expanded uncertainty of the KCRV. Main text.

    2013-11-01

    This study tested whether children's symptoms of inattention and hyperactivity/impulsivity were associated with peer problems and whether these associations were mediated by conduct problems and prosocial behaviors. A community sample of 500 children, including 245 boys and 255 girls, who ranged in age from 6 to 9 years (M = 7.6, SD = 0.91) were recruited. Teachers' report of children's inattention, hyperactivity/impulsivity, conduct problems, prosocial behaviors, and peer problems was collected. Symptoms of inattention and hyperactivity/impulsivity were significantly positively associated with peer problems. Conduct problems were associated with more peer problems and prosocial behaviors with less peer problems. Conduct problems and prosocial behaviors partially mediated the association between hyperactivity/impulsivity and peer problems and fully mediated the inattention-peer problems association. Findings show that prosocial behaviors and conduct problems are important variables that account for some of the negative impact of symptoms of inattention and hyperactivity/impulsivity on peer functioning.

  4. Prospective associations between peer teasing in childhood and young men's obesity.

    PubMed

    Kerr, David C R; Gini, Gianluca

    Being teased and otherwise victimised by peers during childhood increases risk for obesity. However, few prospective studies have considered whether risk extends to adulthood. We tested whether being teased in childhood predicted higher body mass index (BMI) and increased odds of obesity in early adulthood in a community sample of American males. Boys (n=206) were classified as victims of peer teasing or non-victims (n=55 and 151, respectively) based on mother, father, and teacher reports at ages 10-12 years. BMI was assessed at ages 24 or 32 years for 203 of the participants. Family income, parent and child depressive symptoms, child antisocial behaviour, and childhood BMI were assessed at ages 10-13 years and served as control variables. In unadjusted comparisons, childhood victims did not differ significantly from non-victims on BMI (mean [SD]=27.49 [4.53] and 26.97 [4.60], respectively) or rates of obesity (42% and 31%, respectively) in early adulthood. In adjusted models, no group differences emerged for BMI (β [95% confidence interval (CI)]=.02 [-.09 to .13], p=.77) or obesity (odds ratio [95% CI]=1.58 [.67-3.71], p=.30). Peer victimization has been associated with immediate and long-term maladjustment outcomes that are in some cases life threatening. However, our null results do not support that peer victimization significantly increases long-term risk for obesity, and findings are consistent with two other long-term prospective studies of this issue.

    Objective Symptoms of endometriosis, including pelvic pain, back and nerve pain, and gastrointestinal pain, often begin in adolescence. Yet, research on the experience of these debilitating symptoms among young people is scarce. Of particular concern is the influence of adolescent girls’ social context. This study qualitatively examined how, among adolescents, endometriosis and symptoms suggestive of endometriosis is perceived at the family, peer/school and community/society levels. Design Eight focus groups were conducted; vignettes were used to elicit participants’ perceptions of factors that may shape girls’ experiences of endometriosis. Data were analysed using constant comparison analysis. Participants An ethnically diverse sample of girls and boys ages 14–18 (n=54) residing in New York City. Results Fifteen themes emerged and were distilled to eight cross-cutting factors that influence perceptions of endometriosis at different levels of the ecological model: distrust of community healthcare providers, societal stigma of menstruation, peer stigma of endometriosis symptoms, distrust of school healthcare providers, lack of endometriosis knowledge among peers and school personnel, inequitable gender norms, invisibility of symptoms and the stigma of teen sex among parents. Further, these factors may compound symptoms’ impact on individual girl’s social, educational and emotional well-being. Conclusions Findings underscore the importance of understanding the social environment of girls experiencing symptoms suggestive of endometriosis and educating and engaging their peers, family and school personnel to create a supportive, informed social climate. Efforts should specifically include stigma reduction campaigns targeted towards female and male adolescents. PMID:29866728

    2013-01-01

    This study examined peer and non-peer unwanted early sexual experiences (UESE) among 3,689 university students to establish whether peer UESE is as coercive and bothersome as non-peer UESE. A self-report checklist was administered to all consenting students attending an orientation programme at one South African (SA) and one Belgian university. Of the respondents 21% indicated that they had UESE before their 16th birthday (39.2% SA and 13.5% Belgians). Of respondents indicating UESE, 22.4% (173) reported that they had UESE with a person where the age difference was greater than 5 years and 54.2% (418) reported UESE with an age difference less than 5 years. Overall, a statistically significant difference was found between peer exposed and non-peer exposed groups at the time the UESE occurred related to bothersomeness of the UESE. SA men and women experienced more psychological pressure or physical force among the non-peer exposed group than the peer exposed group.

    Common folklore seems to suggest that adolescents are particularly susceptible to peer influence. However, from the literature the exact age differences in susceptibility to peer influence remain unclear. The current study's main focus was to chart the development of general susceptibility to peer pressure in a community sample of 10-18 year olds (N =464) with the recently developed Resistance to Peer Influence Scale (RPI). The one-factor structure of the RPI was cross-validated in the present sample, and the RPI was equally reliable at all ages. As expected, general resistance to peer influence increased during adolescence. In addition, gender differences were most pronounced during mid-adolescence, when girls were more resistant to peer influence than boys. These findings are explained in terms of psychosocial maturation during adolescence.

    PURPOSE We examined the effects of participating in a “train-the-trainer” program and being a peer supporter on metabolic and cognitive/psychological/behavioral parameters in Chinese patients with type 2 diabetes. METHODS In response to our invitation, 79 patients with fair glycemic control (HbA1c <8%) agreed to participate in a “train-the-trainer” program to become peer supporters. Of the 59 who completed the program successfully, 33 agreed to be peer supporters (“agreed trainees”) and were each assigned to support 10 patients for 1 year, with a voluntary extension period of 3 additional years, while 26 trainees declined to be supporters (“refused trainees”). A group of 60 patients with fair glycemic control who did not attend the training program and were under usual care were selected as a comparison group. The primary outcome was the change in average HbA1c levels for the 3 groups from baseline to 6 months. RESULTS At 6 months, HbA1c was unchanged in the trainees (at baseline, 7.1 ± 0.3%; at 6 months, 7.1 ± 1.1%) but increased in the comparison group (at baseline, 7.1 ± 0.5%; at 6 months, 7.3 ± 1.1%. P = .02 for between-group comparison). Self-reported self-care activities including diet adherence and foot care improved in the trainees but not the comparison group. After 4 years, HbA1c remained stable among the agreed trainees (at baseline, 7.0 ± 0.2%; at 4 years: 7.2 ± 0.6%), compared with increases in the refused trainees (at baseline, 7.1 ± 0.4%; at 4 years, 7.8 ± 0.8%) and comparison group (at baseline, 7.1 ± 0.5%; at 4 years, 8.1 ± 0.6%. P = .001 for between-group comparison). CONCLUSIONS Patients with diabetes who engaged in providing ongoing peer support to other patients with diabetes improved their self-care while maintaining glycemic control over 4 years.

    We examined the developmental processes involved in peer problems among children (M age = 10.41 years) previously diagnosed with ADHD at study entry (N = 536) and a comparison group (N = 284). Participants were followed over a 6-year period ranging from middle childhood to adolescence. At four assessment periods, measures of aggression, social skills, positive illusory biases (in the social and behavioral domains), and peer rejection were assessed. Results indicated that children from the ADHD group exhibited difficulties in each of these areas at the first assessment. Moreover, there were vicious cycles among problems over time. For example, peer rejection was related to impaired social skills, which in turn predicted later peer rejection. Problems also tended to “spill over” into other areas, which in turn compromised functioning in additional areas across development, leading to cascading effects over time. The findings held even when controlling for age and were similar for males and females, the ADHD and comparison groups, and among ADHD treatment groups. The results suggest that the peer problems among children with and without ADHD may reflect similar processes; however, children with ADHD exhibit greater difficulties negotiating important developmental tasks. Implications for interventions are discussed. PMID:20883582

    It is possible that men consume a higher amount of legal and illegal drugs than women. This can be assessed using the peer methodology, that is an adaptation of the privileged access interviewers (PAI) method and allows to identify populations in which there may be a tendency to under state a phenomenon (hidden populations) To compare the consumption of legal and illegal drugs by gender. Drug consumption was assessed using a peer methodology in university students between 18 and 26 years of age. A random sample of 56 women (mean age 21.6 years) and 86 men (mean age 21.5 years), was studied. Women tended to report a higher proportion of tobacco consumption than men. Both genders had a similar consumption behavior of alcohol, total legal drugs, marihuana, cocaine, ecstasies and total illegal drugs. Among subjects that recognized the consumption of legal drugs, men have a higher proportion of illicit drug use and women have a higher proportion of smoking. Men have a higher awareness of the damages caused by drug consumption. The results in these small population sample do not support the hypothesis that men have a higher frequency and proportion of illicit drug consumption.

    Studies of peer learning indicate that the model enables students to practice skills useful in their future profession, such as communication, cooperation, reflection and independence. However, so far most studies have used a qualitative approach and none have used a quasi-experimental design to study effects of nursing students' peer learning in clinical practice. To investigate the effects of peer learning in clinical practice education on nursing students' self-rated performance. Quasi-experimental. The study was conducted during nursing students' clinical practice. All undergraduate nursing students (n=87) attending their first clinical practice were approached. Seventy students out of 87 answered the questionnaires at both baseline and follow-up (42 of 46 in the intervention group and 28 of 39 in the comparison group). During the first two weeks of the clinical practice period, all students were supervised traditionally. Thereafter, the intervention group received peer learning the last two weeks, and the comparison group received traditional supervision. Questionnaire data were collected on nursing students' self-rated performance during the second (baseline) and last (follow-up) week of their clinical practice. Self-efficacy was improved in the intervention group and a significant interaction effect was found for changes over time between the two groups. For the other self-rated variables/tests, there were no differences in changes over time between the groups. Studying each group separately, the intervention group significantly improved on thirteen of the twenty variables/tests over time and the comparison group improved on four. The results indicate that peer learning is a useful method which improves nursing students' self-efficacy to a greater degree than traditional supervision does. Regarding the other self-rated performance variables, no interaction effects were found. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

    The treatment of bleeding disorders improved in the last decades. However, the effect of growing up with bleeding disorders on developmental, emotional, and social aspects is understudied. Therefore, this study assesses HRQOL, developmental milestones, and self-esteem in Dutch young adults (YA) with bleeding disorders compared to peers. Ninety-five YA (18-30 years) with bleeding disorders (78 men; mean 24.7 years, SD 3.5) and 17 women (mean 25.1 years, SD 3.8) participated and completed the Pediatric Quality of Life Inventory Young Adult version, the Course of Life Questionnaire, and the Rosenberg Self-Esteem Scale. Differences between patients with bleeding disorders and their peers, and between hemophilia severity groups, were tested using Mann-Whitney U tests. YA men with bleeding disorders report a slightly lower HRQOL on the total scale, physical functioning, and school/work functioning in comparison to healthy peers (small effect sizes). YA men with severe hemophilia report more problems on the physical functioning scale than non-severe hemophilia. YA men with bleeding disorders achieved more psychosexual developmental milestones than peers, but show a delay in 'paid jobs, during middle and/or high school.' A somewhat lower self-esteem was found in YA men with bleeding disorders in comparison to peers (small effect size). For YA women with bleeding disorders, no differences were found on any of the outcomes in comparison to peers. This study demonstrates some impairments in HRQOL and self-esteem in YA men with bleeding disorders. By monitoring HRQOL, problems can be identified early, especially with regard to their physical and professional/school functioning.

    2011-02-01

    We used principles of community-based participatory research to develop and pilot test a 5-week intervention for middle school students, Students for Nutrition and eXercise (SNaX). SNaX aimed to translate school obesity-prevention policies into practice with peer advocacy of healthy eating and school cafeteria changes. A total 425 seventh graders (63% of all seventh graders) in the intervention school were surveyed at baseline regarding cafeteria attitudes and sugar-sweetened beverage consumption; of the 425 students, 399 (94%) were surveyed again at 1-month post-intervention. School cafeteria records were obtained from two schools: the intervention school and a nonrandomized selected comparison school with similar student socio-demographic characteristics. A total of 140 students in the intervention school were trained as peer advocates. In the intervention school, cafeteria attitudes among peer advocates significantly improved over time (approximately one-third of a standard deviation), whereas cafeteria attitudes of non-peer advocates remained stable; the improvement among peer advocates was significantly greater than the pre-post-change for non-peer advocates (b = .71, p < .001). Peer advocates significantly reduced their sugar-sweetened beverage intake (sports and fruit drinks), from 33% before intervention to 21% after intervention (p = .03). Cafeteria records indicated that servings of fruit and healthier entrées (salads, sandwiches, and yogurt parfaits) significantly decreased in the comparison school and significantly increased in the intervention school; the magnitude of changes differed significantly between the schools (p < .001). As compared with the non-peer advocates, peer advocates appeared to benefit more from the intervention. Future research should consider engaging parents, students, and other key community stakeholders to determine acceptable and sustainable cafeteria changes.

    Purpose Our previous study found it feasible for a preschooler with cerebral palsy (CP) to use a power mobility device in his classroom but noted a lack of typical socialization. The purpose of this follow-up study was to determine the feasibility of providing mobility and socialization training for this child. Methods Will, a 3-year-old with CP, one comparison peer, two preschool teachers, and two therapists were filmed daily during a training and post-training phase. Adult-directed training was provided in the classroom by therapists and teachers during the training phase. Mobility and socialization measures were coded from video. Outcomes During training, Will demonstrated higher socialization but less mobility than the comparison peer. Post training, Will socialized less but was more mobile, though less mobile than the comparison peer. Discussion Short-term, adult-directed power mobility and socialization training appears feasible for the preschool classroom. Important issues regarding socialization and power mobility are discussed. PMID:22090084

    Background The nature and characteristics of the peer social networks of young children with Down syndrome in classroom settings were examined within a developmental framework. Method Comparisons were made with younger typically developing children matched on mental age and typically developing children matched on chronological age. Results Similar patterns were found for all three groups for most peer social network measures. However, group differences were obtained for measures of teacher assistance and peer interactions in unstructured situations. Conclusions Positive patterns appeared to be related to the social orientation of children with Down syndrome and the special efforts of teachers to support children’s peer social networks. Findings also suggested that fundamental peer competence problems for children with Down syndrome remain and may best be addressed within the framework of contemporary models of peer-related social competence.

    Objective SENSE Theatre is a novel intervention program aimed at improving reciprocal social interaction in youth with autism spectrum disorder (ASD) using behavioral strategies and theatrical techniques in a peer-mediated model. Previous research using a 3-month model showed improvement in face perception, social interaction, and reductions in stress. The current study assessed a 2-week summer camp model. Method Typically developing peers were trained and paired with ASD youth (8–17 years). Social perception and interaction skills were measured before and after treatment using neuropsychological and parental measures. Behavioral coding by reliable, independent raters was conducted within the treatment context (theatre) and outside the setting (playground). Salivary cortisol levels to assess physiological arousal were measured across contexts (home, theatre, and playground). A pretest-posttest design for within-group comparisons was used, and pre-specified pairwise comparisons were achieved using a nonparametric Wilcoxon signed rank test. Results Significant differences were observed in face processing, social awareness, and social cognition (p<0.05). Duration of interaction with familiar peers increased significantly over the course of treatment (p<0.05) while engagement with novel peers outside the treatment setting remained stable. Cortisol levels rose on the first day of camp compared to home values yet declined by the end of treatment and further reduced during post-treatment play with peers. Conclusions Results corroborate previous findings that the peer-mediated theatre program contributes to improvement in core social deficits in ASD using a short-term, summer camp treatment model. Future studies will explore treatment length and peer familiarity to optimize and generalize gains. PMID:24150989

    This study examined longitudinal data linking marital aggression with child peer competence in kindergarten. The study compared three conceptual models for understanding the relation between marital aggression and child peer competence. Model 1 examines the direct effects of marital aggression, parental alcoholism, and parenting on child peer competence, model 2 posits that this relation is mediated by child social problem solving abilities (social information processing theory), while model 3 proposes that the relation is mediated by parental warmth/sensitivity (spillover theory). Structural Equation Modeling was most supportive of models 1 and 3 indicating that parenting behavior, but not social problem solving, partially mediates the relation between marital conflict and child peer competence.

  7. Adaptive Peer Sampling with Newscast

    NASA Astrophysics Data System (ADS)

    Tölgyesi, Norbert; Jelasity, Márk

    The peer sampling service is a middleware service that provides random samples from a large decentralized network to support gossip-based applications such as multicast, data aggregation and overlay topology management. Lightweight gossip-based implementations of the peer sampling service have been shown to provide good quality random sampling while also being extremely robust to many failure scenarios, including node churn and catastrophic failure. We identify two problems with these approaches. The first problem is related to message drop failures: if a node experiences a higher-than-average message drop rate then the probability of sampling this node in the network will decrease. The second problem is that the application layer at different nodes might request random samples at very different rates which can result in very poor random sampling especially at nodes with high request rates. We propose solutions for both problems. We focus on Newscast, a robust implementation of the peer sampling service. Our solution is based on simple extensions of the protocol and an adaptive self-control mechanism for its parameters, namely—without involving failure detectors—nodes passively monitor local protocol events using them as feedback for a local control loop for self-tuning the protocol parameters. The proposed solution is evaluated by simulation experiments.

    Peer effects, in which the behavior of an individual is affected by the behavior of their peers, are central to social science. Because peer effects are often confounded with homophily and common external causes, recent work has used randomized experiments to estimate effects of specific peer behaviors. These experiments have often relied on the experimenter being able to randomly modulate mechanisms by which peer behavior is transmitted to a focal individual. We describe experimental designs that instead randomly assign individuals' peers to encouragements to behaviors that directly affect those individuals. We illustrate this method with a large peer encouragement design on Facebook for estimating the effects of receiving feedback from peers on posts shared by focal individuals. We find evidence for substantial effects of receiving marginal feedback on multiple behaviors, including giving feedback to others and continued posting. These findings provide experimental evidence for the role of behaviors directed at specific individuals in the adoption and continued use of communication technologies. In comparison, observational estimates differ substantially, both underestimating and overestimating effects, suggesting that researchers and policy makers should be cautious in relying on them.

    2015-05-01

    Sociocultural theory of body dissatisfaction posits that internalization of the media ideal and appearance comparison are predictors of body dissatisfaction, a key risk factor for eating disorders. However, no data exist regarding the longitudinal relationships between these variables. The aim of this study was to explore longitudinal relationships among internalization of the media-ideal, social appearance comparison, and body dissatisfaction. A sample of 277 Grade 7 school girls (M age = 12.77 years, SD = 0.44) completed measures of internalization of the media ideal, social appearance comparison, and body dissatisfaction at baseline, 8 months, and 14 months. Path analyses indicated that baseline internalization of the media ideal predicted social appearance comparison and body dissatisfaction at 8 months, and social appearance comparison at 8 months predicted body dissatisfaction at 14 months. A reciprocal effect emerged with body dissatisfaction at 8 months predicting internalization of the media ideal at 14 months. The findings inform sociocultural theory of body dissatisfaction, suggesting that internalization of the media ideal precedes and predicts appearance comparison and that body image interventions that target internalization of the media ideal, and social appearance comparison as well as body dissatisfaction are likely to be effective.

    The problems associated with violence during adolescence have been on the rise in recent decades. Many studies have focused only on environmental causes or individual causes of violence, although a combination of both variables would seem to be the best option for prediction. The current study aims to assess the relevance of individual characteristics (personality traits, intelligence, and historical and clinical factors linked to the risk of violence), contextual risk factors and protective factors in explaining antisocial and delinquent behaviors in adolescence by comparing three different samples: a community sample, a sample at risk of social exclusion, and a sample of juvenile offenders. The results show that the samples at risk of social exclusion and the sample of juvenile offenders have a very similar profile in terms of personality traits and intelligence, although they differ from the community sample. However, these two samples do differ in such contextual variables as peer delinquency, poor parental management, community disorganization, or early caregiver disruption. PMID:29104551

    Symptoms of endometriosis, including pelvic pain, back and nerve pain, and gastrointestinal pain, often begin in adolescence. Yet, research on the experience of these debilitating symptoms among young people is scarce. Of particular concern is the influence of adolescent girls' social context. This study qualitatively examined how, among adolescents, endometriosis and symptoms suggestive of endometriosis is perceived at the family, peer/school and community/society levels. Eight focus groups were conducted; vignettes were used to elicit participants' perceptions of factors that may shape girls' experiences of endometriosis. Data were analysed using constant comparison analysis. An ethnically diverse sample of girls and boys ages 14-18 (n=54) residing in New York City. Fifteen themes emerged and were distilled to eight cross-cutting factors that influence perceptions of endometriosis at different levels of the ecological model: distrust of community healthcare providers, societal stigma of menstruation, peer stigma of endometriosis symptoms, distrust of school healthcare providers, lack of endometriosis knowledge among peers and school personnel, inequitable gender norms, invisibility of symptoms and the stigma of teen sex among parents. Further, these factors may compound symptoms' impact on individual girl's social, educational and emotional well-being. Findings underscore the importance of understanding the social environment of girls experiencing symptoms suggestive of endometriosis and educating and engaging their peers, family and school personnel to create a supportive, informed social climate. Efforts should specifically include stigma reduction campaigns targeted towards female and male adolescents. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Several studies examining alcohol use and depression in youth have focused on documenting prevalence of overlap, or temporal ordering in longitudinal samples. Fewer studies have examined pathways connecting alcohol use and depression over time. This study examined gender differences between depression and alcohol use across adolescence while examining peer and family pathways as possible mediators of effects. Data was collected longitudinally from 593 families from three urban public middle schools in the United States. Participants were recruited in 6th grade and followed through 9th grade. We examined gender differences using a nested model comparison approach. Results indicated the association between depression and alcohol use differs by gender. For males, depression and alcohol use were independent across adolescence, and no significant indirect pathways were observed. For females, bidirectional effects were found between alcohol use and depression, as well as an indirect effect from depression to alcohol use via peer deviance. PMID:28167374

    In youth mental health services, consumer participation is essential, but few implementation strategies exist to engage young consumers. This project evaluated an intervention implemented in an Australian youth mental health service that utilized peer workers to promote shared decision making via an online tool. All new clients ages 16-25 were invited to participate in this nonrandomized comparative study, which used a historical comparison group (N=80). Intervention participants (N=149) engaged with a peer worker and used the online tool before and during their intake assessment. Pre- and postintake data were collected for both groups; measures included decisional conflict, perceived shared decision making, and satisfaction. A series of paired t tests, analyses of variance, and multiple regressions were conducted to assess differences in scores across intervention and comparison groups and pre- and postintake assessments. Ratings of perceived shared decision making with intake workers were higher in the intervention group than in the comparison group (p=.015). In both groups, decisional conflict scores were significantly lower after the intake assessment (p<.001 for both groups). Both perceived shared decision making and lower decisional conflict were associated with satisfaction (p<.015). Young people who participated in an intervention that combined peer work and shared decision making reported feeling more involved in their assessment. Feeling involved and having lower decisional conflict after seeing an intake worker were important for client satisfaction. These findings demonstrate the importance of both peer work and shared decision making for promoting optimal outcomes in youth mental health services.

    Social Emotional NeuroScience Endocrinology Theatre is a novel intervention program aimed at improving reciprocal social interaction in youth with autism spectrum disorder (ASD) using behavioral strategies and theatrical techniques in a peer-mediated model. Previous research using a 3-month model showed improvement in face perception, social interaction, and reductions in stress. The current study assessed a 2-week summer camp model. Typically developing peers were trained and paired with ASD youth (8-17 years). Social perception and interaction skills were measured before and after treatment using neuropsychological and parental measures. Behavioral coding by reliable, independent raters was conducted within the treatment context (theatre) and outside the setting (playground). Salivary cortisol levels to assess physiological arousal were measured across contexts (home, theatre, and playground). A pretest-posttest design for within-group comparisons was used, and prespecified pairwise comparisons were achieved using a nonparametric Wilcoxon signed-rank test. Significant differences were observed in face processing, social awareness, and social cognition (P < 0.05). Duration of interaction with familiar peers increased significantly over the course of treatment (P < 0.05), while engagement with novel peers outside the treatment setting remained stable. Cortisol levels rose on the first day of camp compared with home values yet declined by the end of treatment and further reduced during posttreatment play with peers. Results corroborate previous findings that the peer-mediated theatre program contributes to improvement in core social deficits in ASD using a short-term, summer camp treatment model. Future studies will explore treatment length and peer familiarity to optimize and generalize gains. © 2013 International Society for Autism Research, Wiley Periodicals, Inc.

    Objectives Mobile JXTA (Juxtapose) gaining momentum and has attracted the interest of doctors and patients through P2P service that transmits messages. Audio and video can also be transmitted through JXTA. The use of mobile streaming mechanism with the support of mobile hospital management and healthcare system would enable better interaction between doctors, nurses, and the hospital. Experimental results demonstrate good performance in comparison with conventional systems. This study evaluates P2P JXTA/JXME (JXTA functionality to MIDP devices.) which facilitates peer-to-peer application+ using mobile-constraint devices. Also a proven learning algorithm was used to automatically send and process sorted patient data to nurses. Methods From December 2010 to December 2011, a total of 500 patients were referred to our hospital due to minor health problems and were monitored. We selected all of the peer groups and the control server, which controlled the BMO (Block Medical Officer) peer groups and BMO through the doctor peer groups, and prescriptions were delivered to the patient’s mobile phones through the JXTA/ JXME network. Results All 500 patients were registered in the JXTA network. Among these, 300 patient histories were referred to the record peer group by the doctors, 100 patients were referred to the external doctor peer group, and 100 patients were registered as new users in the JXTA/JXME network. Conclusion This system was developed for mobile streaming applications and was designed to support the mobile health management system using JXTA/ JXME. The simulated results show that this system can carry out streaming audio and video applications. Controlling and monitoring by the doctor peer group makes the system more flexible and structured. Enhanced studies are needed to improve knowledge mining and cloud-based M health management technology in comparison with the traditional system. PMID:24159509

    To explore what peer supporters, patients and their relatives want and gain from peer support in cancer care. Focus group interviews with peer supporters, and in-depth interviews with peer supporters, patients and relatives (N=38) and observations of daily activities in a Vardesenter ("Cairn Centre"). Peer supporters helped cancer patients and relatives with coping in and outside the hospital in several ways: (1) conveying hope and providing ways to cope in situations where despair would often be prevalent, thus protecting against unhealthy stress; (2) being someone who had the same experiences of disease and treatment, and thus providing a framework for positive social comparisons; and (3) to be an important supplement to family and health care providers. To be working as a peer supporter was also found to be positive and important for the peer supporters themselves. The peer support program represented a valuable supplement to informal support from family and friends and healthcare providers, and gave the peer supporters a new role as "professionally unprofessional". Organised peer support represents a feasible intervention to promote coping for cancer survivors. Copyright © 2017 Elsevier B.V. All rights reserved.

    The adherence to masculine norms has been suggested to be influenced by social settings and context. Prisons have been described as a context where survival is dependent on adhering to strict masculine norms that may undermine reintegration back into the larger society. This study attempted to examine the relationship between masculine norms, peer support, and an individual’s length of incarceration on a sample of 139 African American men taking part in a pre-release community re-entry program. Results indicate that peer support was associated with length of incarceration and the interaction between the endorsement of masculine norms and peer support significantly predicted the length of incarceration for African American men in this sample. Implications for incarcerated African American men and future research directions are discussed. PMID:25866486

    Andrade, Brendan F; Tannock, Rosemary

    2014-06-01

    This prospective 2-year longitudinal study tested whether inattentive and hyperactive/impulsive symptom dimensions predicted future peer problems, when accounting for concurrent conduct problems and prosocial skills. A community sample of 492 children (49 % female) who ranged in age from 6 to 10 years (M = 8.6, SD = .93) was recruited. Teacher reports of children's inattention, and hyperactivity/impulsivity symptoms, conduct problems, prosocial skills and peer problems were collected in two consecutive school years. Elevated inattention and hyperactivity/impulsivity in Year-1 predicted greater peer problems in Year-2. Conduct problems in the first and second years of the study were associated with more peer problems, and explained a portion of the relationship between inattention and hyperactivity/impulsivity with peer problems. However, prosocial skills were associated with fewer peer problems in children with elevated inattention and hyperactivity/impulsivity. Inattention and hyperactivity/impulsivity have negative effects on children's peer functioning after 1-year, but concurrent conduct problems and prosocial skills have important and opposing impacts on these associations.

    2009-01-01

    Peer rejection and aggression in the early school years were examined for their relevance to early starting conduct problems. The sample of 657 boys and girls from 4 geographical locations was followed from 1st through 4th grades. Peer rejection in 1st grade added incrementally to the prediction of early starting conduct problems in 3rd and 4th grades, over and above the effects of aggression. Peer rejection and aggression in 1st grade were also associated with the impulsive and emotionally reactive behaviors found in older samples. Being rejected by peers subsequent to 1st grade marginally added to the prediction of early starting conduct problems in 3rd and 4th grades, controlling for 1st grade ADHD symptoms and aggression. Furthermore, peer rejection partially mediated the predictive relation between early ADHD symptoms and subsequent conduct problems. These results support the hypothesis that the experience of peer rejection in the early school years adds to the risk for early starting conduct problems. PMID:12041708

    PubMed

    Locock, Louise; Brown, Janice B

    2010-10-01

    This paper explores attitudes to peer support among people with Motor Neurone Disease (MND) and their family carers. It reports findings from a secondary analysis of data from two UK interview studies conducted by the authors. The process of secondary analysis is reported in detail. 48 people with MND and 22 carers were interviewed in 2005-2007. The authors identified narrative extracts on peer support from their own datasets and exchanged them for independent thematic analysis. Subsequent discussion, drawing on literature on support groups and social comparison, led to an exploration of two overarching themes: valuing camaraderie and comparison, and choosing isolation. Findings suggest that social comparison theory is a useful framework for analysing attitudes to MND support groups, but that on its own it is insufficient. 'Valuing camaraderie and comparison' explains how support groups offer practical and social support, as well as beneficial opportunities for social comparison. Seeing others coping well with the condition can provide hope, while downward comparison with those worse off can also make people feel better about their own situation. However, most people are also shocked and saddened by seeing others with the condition. Tension of identity can occur when group membership starts to define the individual as 'a person with MND, rather than the person I am that happens to have MND'. Choosing isolation can be a deliberate defensive strategy, to protect oneself from witnessing one's possible future. Levels of involvement may change over time as people struggle with their changing needs and fears. Copyright © 2010 Elsevier Ltd. All rights reserved.

    Ecstasy (MDMA) use is relatively common among young adults in many developed countries. However, little is known about how young non-users are first introduced to Ecstasy, including the relative contribution of peer networks and individual risk factors. We assess the role of social contact with Ecstasy-using peers in regard to young adults' exposure to offers of Ecstasy, using data from the Natural History Study, a population-based study conducted in Australia. Population screening of young adults (19- to 23-year-olds) identified a sample of young Ecstasy users (N = 315) and a comparison group of Ecstasy-naïve participants (N = 199). Two outcomes are considered: being exposed to any Ecstasy offers and being exposed to > 3 offers. Extensive social contact with Ecstasy users was defined as knowing > 10 Ecstasy users. Of the Ecstasy-naïve young adults, > 40% had ever received Ecstasy offers. Extensive social contact with Ecstasy users independently predicted exposure to multiple (> 3) Ecstasy offers for Ecstasy-naïve young adults. These findings indicate that Ecstasy offers are widespread among users and non-users of Ecstasy. For non-users, exposure to Ecstasy offers occurs through social contact with drug-using peers independently of individual risk factors. The pervasiveness of Ecstasy offers suggests that universal education concerning Ecstasy use is required.

  15. Pathways From Depressive Symptoms to Low Social Status

    2012-01-01

    This research examined two pathways through which depressive symptoms contribute to low social status (i.e., neglect and rejection) within the peer group over time: (a) depressive symptoms promote socially helpless behavior and consequent neglect by peers; and (b) depressive symptoms promote aggressive behavior and consequent rejection by peers. These pathways were investigated in independent samples of youth at two developmental stages: middle childhood (2nd – 4th grade) and early adolescence (5th – 7th grade). In both Study 1 (M age = 7.97, SD = .37; 338 girls, 298 boys) and Study 2 (M age = 11.74, SD = .68; 305 girls, 300 boys), youth and their teachers completed questionnaires at three waves. Multi-group comparison path analyses were conducted to examine sex differences in the models. Consistent with expectations, two pathways emerged through which depressive symptoms undermined subsequent social status. Support was not found for the reverse direction of effect nor for developmental or sex differences in the pathways with one exception: In early adolescence, neglect directly predicted depressive symptoms. These findings suggest specificity but also heterogeneity in the effects of depressive symptoms on social status, and identify behaviors that may be targeted for preventing the persistence of depression and its interpersonal consequences.

    This study investigated the relative influence of perceived parent and peer disapproval for using drugs on youth intentions to use drugs. In a cross-sectional design, sixth and eighth grade students (N = 1,649) completed surveys that included measures of parent disapproval, peer disapproval, and intentions to use drugs in the future. Parent influences were more salient for sixth graders, whereas peer influences were predominant for eighth graders. Peer disapproval was significantly evident in the sixth grade sample, as was parent disapproval in the eighth grade sample. Additionally, girls' drug use intentions were higher than were boys'. These findings suggest that parents can have a robust protective role over and above peer influences and that girls' intentions to use substances deserve increased attention. Editors' Strategic Implications: These findings, if replicated, should help practitioners develop developmentally appropriate strategies and programs for substance use prevention.

    Near-peer and faculty staff tutors may facilitate problem-based learning (PBL) through different means. Near-peer tutors are thought to compensate for their lack of subject matter expertise with greater adeptness at group facilitation and a better understanding of their learners. However, theoretical explanations of tutor effectiveness have been developed largely from recollections of tutor practices gathered through student evaluation surveys, focus groups and interviews. A closer look at what happens during PBL sessions tutored by near-peers and faculty members seems warranted to augment theory from a grounded perspective. We conducted an observational study to explore interactional practices during PBL tutorials at our medical school, at which near-peer tutoring of Year 2 students is an established practice. Between October 2014 and May 2015, video-recordings were made of nine purposively sampled tutor groups using three tutor types (near-peer, clinical faculty and basic science faculty staff) across three systems-based units. An investigator team comprising a Year 2 student, a Year 4 student and a behavioural scientist independently analysed the videos until their observations reached saturation and then met face to face to discuss their detailed field notes. Through constant comparison, narratives of tutor practices and group dynamics were generated for each of the nine tutor groups, representing the collective impressions of the members of the investigator team. Variation was greater within than across tutor types. Tutors' practices idiosyncratically and sometimes substantially diverged from PBL principles, yet all tutors attempted to convey authority or 'insider' status with respect to the short- and long-term goals of medical education. Students prompted these status demonstrations by expressing gratitude, asking questions and exhibiting analogous status demonstrations themselves. Understanding the socio-cognitive nature of tutoring from a grounded perspective may provide a means to develop faculty staff of all types to better meet learner needs in a principled fashion. © 2016 John Wiley & Sons Ltd.

    This prospective study examines family predictors of distress among survivors of childhood cancer and comparison peers during the transition to emerging adulthood. Children with cancer (n = 55), comparison peers (n = 60), and parents completed measures of distress, family environment, social support, and demographic characteristics during initial treatment, as well as follow-up measures of young adult distress and demographic characteristics soon after participants turned 18 years old. Severity of initial treatment and late effects were rated by healthcare providers for participants with cancer. For all participants, mother and father report of initial parent distress was associated with their report of young adult distress at follow-up. Young adult gender moderated this association. For survivors of childhood cancer, severity of initial treatment and late effects also moderated the association between parent and young adult distress. Improving parent distress may help reduce child distress in general. For survivors specifically, ameliorating the impact of initial treatment and long-term physical problems may be beneficial.

    2015-01-01

    Using a field experiment in a 401(k) plan, we measure the effect of disseminating information about peer behavior on savings. Low-saving employees received simplified plan enrollment or contribution increase forms. A randomized subset of forms stated the fraction of age-matched coworkers participating in the plan or age-matched participants contributing at least 6% of pay to the plan. We document an oppositional reaction: the presence of peer information decreased the savings of nonparticipants who were ineligible for 401(k) automatic enrollment, and higher observed peer savings rates also decreased savings. Discouragement from upward social comparisons seems to drive this reaction. PMID:26045629

    Drawing from social comparison theory, parasocial interaction (PSI) theory, and the literature on envy, a randomized experiment addressed the dynamics of body image, fame, and envy in the context of foodies' foodporn posting on Instagram. Using a 2 (foodie's body type: fat vs. thin) × 2 (foodie's Instagram popularity: unpopular vs. popular) between-subjects design, this experiment (N = 141) examined the effects of an Instagram foodie's body shape and popularity level on peer Instagram users' eating intention, envy, and PSI with the Instagram foodie. The results showed main effects of an Instagram foodie's body shape on peer users' eating intention, and moderating effects of users' self-esteem, body mass index, perfectionism, anorexia, and bulimia nervosa. Additionally, envy mediated the effects of the Instagram foodie's body shape and popularity on peer users' PSI with the foodie and intention to build an Instagram-based friendship. Theoretical contributions to the literature on social comparison and eating disorder and practical implications for fitspiration and social media-based health interventions are discussed.

    2013-01-01

    Objective: The purpose of this study was to identify overlap and violence types between peer and dating aggression and victimization using latent class analysis (LCA) among a sample of aggressive adolescents with a history of alcohol use and to identify risk and protective factors associated with each violence class. Method: From September 2006 to September 2009, a systematic sample of patients (14–18 years old) seeking care in an urban emergency department were approached. Adolescents reporting any past-year alcohol use and aggression completed a survey using validated measures including types of violence (severe and moderate aggression, severe and moderate victimization with both peers and dating partners). Using LCA, violence classes were identified; correlates of membership in each LCA class were determined. Results: Among this sample (n = 694), LCA identified three classes described as (a) peer aggression (PA) (52.2%), (b) peer aggression + peer victimization (PAPV) (18.6%), and (c) multiple domains of violence (MDV) (29.3%). Compared with those in the PA class, those in the PAPV class were more likely to be male, report injury in a fight, and have delinquent peers. Compared with the PA class, those in the MDV class were more likely to be female, African American, report injury in a fight, carry a weapon, experience negative consequences from alcohol use, and have delinquent peers and more family conflict. Compared with the PAPV class, those in the MDV class were likely to be female, African American, receive public assistance, carry a weapon, experience negative consequences from alcohol use, and use marijuana. Conclusions: There is extensive overlap of victimization and aggression in both peer and dating relationships. Also, those with high rates of violence across relationships have increased alcohol misuse and marijuana use. Thus, violence-prevention efforts should consider addressing concomitant substance use.

    2008-01-01

    CCQM-K9.2 was performed supplementary to the key comparison CCQM-K9 on the pH determination of a phosphate buffer with nominal pH ~ 6.9 (at 25 °C). The sample composition was very similar in both comparisons. Only the source of the starting material used for sample preparation was different. The comparison was restricted to the use of the primary method for pH (Harned cell measurement) as defined in the IUPAC Recommendations [2]. The measurement temperatures were 15 °C, 25 °C, 37 °C. CCQM-K9.2, CCQM-K.9 and the first supplementary comparison CCQM-K9.1 [5] are activities of the Electrochemical Working Group (EAWG) of the CCQM. All three comparisons were coordinated by the PTB, Germany. The Danish Primary Laboratory (DPL) successfully took part in the CCQM-K9. Meanwhile the primary set-up for pH in Denmark moved from DPL affiliated to Radiometer Medical to DFM, Denmark. The subsequent comparison allows assessing the degree of equivalence for the measurement of pH at DFM after the move. Due to the interest of other laboratories in demonstrating their progress in pH measurements on the primary level the CCQM-K9.2 supplementary comparison was extended to other participants than DFM, namely NMIJ, VNIIFTRI, INMETRO and CMI. The reported quantity for CCQM-K9.2 was not the pH of the sample but the acidity function at zero chloride molality (see chapter 12). To calculate the pH value from the acidity function it is necessary to know the ionic strength of the sample buffer solution, which was undisclosed by the coordinator. With the exception of the Czech Metrology Institute, CMI, good agreement in the determined acidity function is found between the participants. The results reported by DFM and by PTB agree within their measurement uncertainty at all measurement temperatures. Main text. To reach the main text of this paper, click on Final Report.

  16. Peer Interventions to Promote Health: Conceptual Considerations

    PubMed Central

    Simoni, Jane M.; Franks, Julie C.; Lehavot, Keren; Yard, Samantha S.

    2013-01-01

    Peers have intervened to promote health since ancient times, yet few attempts have been made to describe theoretically their role and their interventions. After a brief overview of the history and variety of peer-based health interventions, a 4-part definition of peer interveners is presented here with a consideration of the dimensions of their involvement in health promotion. Then, a 2-step process is proposed as a means of conceptualizing peer interventions to promote health. Step 1 involves establishing a theoretical framework for the intervention’s main focus (i.e., education, social support, social norms, self-efficacy, and patient advocacy), and Step 2 involves identifying a theory that justifies the use of peers and might explain their impact. As examples, the following might be referred to: theoretical perspectives from the mutual support group and self-help literature, social cognitive and social learning theories, the social support literature, social comparison theory, social network approaches, and empowerment models.

  17. Computer-Based Methods for Collecting Peer Nomination Data: Utility, Practice, and Empirical Support.

    PubMed

    van den Berg, Yvonne H M; Gommans, Rob

    2017-09-01

    New technologies have led to several major advances in psychological research over the past few decades. Peer nomination research is no exception. Thanks to these technological innovations, computerized data collection is becoming more common in peer nomination research. However, computer-based assessment is more than simply programming the questionnaire and asking respondents to fill it in on computers. In this chapter the advantages and challenges of computer-based assessments are discussed. In addition, a list of practical recommendations and considerations is provided to inform researchers on how computer-based methods can be applied to their own research. Although the focus is on the collection of peer nomination data in particular, many of the requirements, considerations, and implications are also relevant for those who consider the use of other sociometric assessment methods (e.g., paired comparisons, peer ratings, peer rankings) or computer-based assessments in general. © 2017 Wiley Periodicals, Inc.

  18. Bids for joint attention by parent-child dyads and by dyads of young peers in interaction.

    PubMed

    Ninio, Anat

    2016-01-01

    Before they are 3;0-3;6, children typically do not engage with peers in focused interaction, although they do with adults. With parents, children interact around the 'here-and-now'. We hypothesize that young peers do not attempt to establish joint attention to present objects. Using the CHILDES database, we compared attention-directives produced by parents to children, children to peers, and children to parents. Of 391 English-speaking parents, 88% generated attention-directives, mostly Look!, See!, and Watch! Of 15 children (2;10-3;7) engaging in dyadic peer-interaction, only 26% produced such utterances. By comparison, 62% of 268 children (1;2-3;3) addressed such directives to parents. Interaction with peers in young children does not involve joint attention to a shared environmental focus, although it does with parents. The reason may be pragmatic: shared attention in parent-child dyads is a means to get information or help; it may seem pointless for a child to address such directives to a peer.

  19. Psychosocial predictors in consideration of cosmetic surgery among women.

    PubMed

    Nerini, Amanda; Matera, Camilla; Stefanile, Cristina

    2014-04-01

    This study aimed to analyze the influence of psychosocial factors on the consideration of cosmetic surgery. The authors hypothesized that the internalization of thin ideals and social comparisons mediate the relationship between media pressure, family and peer influence (appearance conversations, perception of teasing, and peer attributions), and the desire to pursue cosmetic surgery. The study participants were 429 Italian women (mean age, 33 years). They completed a questionnaire containing the Appearance Conversations With Friends Scale, the Perception of Teasing Scale for Friends, the Peer Attribution Scale, the "Pressure and Internalization-General" subscales of the Sociocultural Attitudes Towards Appearance Questionnaire-3, the Feedback on Physical Appearance Scale, the Physical Appearance Comparison Scale, and the "Consider" subscale of the Acceptance of Cosmetic Surgery Scale. Hierarchical linear regression was performed. The results indicated that media pressure and appearance conversations with peers predicted the outcome variable through the full mediation of internalization of thin ideals. The relation between peer attributions and interest in cosmetic surgery was partially mediated by internalization of thin ideals. Although social comparison was significantly related to both sociocultural variables and consideration of cosmetic procedures, it was not a significant mediator of this relationship. Neither family influence nor perception of teasing predicted the outcome variable. Overall, these results provide important information about the factors implicated in the consideration of cosmetic surgery by women. This research confirms that cosmetic surgeons need to adopt a base psychological approach. This journal requires that authors assign a level of evidence to each article.

    2018-04-01

    Male perpetration of intimate partner violence (IPV) against women in Tanzania is widespread. Theory and empirical evidence suggest peer networks may play an important role in shaping IPV perpetration, although research on this topic in sub-Saharan Africa is limited. Grounded in social learning theory, social influence theory, and the theory of gender and power, the purpose of this study was to examine whether and how peer networks influence men's perpetration of IPV in Dar es Salaam, Tanzania. We conducted in-depth interviews (n = 40) with a sub-sample of 20 men enrolled in the control condition of an ongoing cluster-randomised controlled trial. We purposively sampled participants who previously reported perpetrating physical IPV. To analyse the data, we generated narrative summaries and conducted thematic and interpretative coding. We saw no evidence that men self-selected into peer networks with certain values or behaviours. Rather, men described several mechanisms through which their peers influenced the perpetration of IPV, including: (1) the internalisation of peer network norms, (2) pressure to conform to peer network norms and (3) the direct involvement of peers in shaping couple power dynamics. Our findings suggest that peer networks influence men's perpetration of IPV and should be targeted in future programmes and interventions.

    Objective Evaluate the acceptability, feasibility, and preliminary outcomes of a peer-mediated intervention to improve social competence of brain tumor survivors and classmates. Methods Twelve childhood brain tumor survivors and 217 classroom peers in intervention (n = 8) or comparison (n = 4) classrooms completed measures of social acceptance and reputation at two time points in the year. The intervention (5–8 sessions over 4–6 weeks) taught peer leaders skills for engaging classmates. Individual and classroom outcomes were analyzed with ANCOVA. Results Recruitment rates of families of brain tumor survivors (81%) and schools (100%) were adequate. Peer leaders reported satisfaction with the intervention. Preliminary outcome data trended toward some benefit in increasing the number of friend nominations for survivors of brain tumors but no changes in other peer-reported metrics. Preliminary results also suggested some positive effects on classroom levels of victimization and rejection. Conclusions A peer-mediated intervention was acceptable to families of brain tumor survivors and feasible to implement in schools. Findings warrant a larger trial to evaluate improvements for children with brain tumors and their peers. PMID:27355881

    Injection drug users in Tirana, Albania and St. Petersburg, Russia were recruited into a study assessing HIV-related behaviors and HIV serostatus using Respondent Driven Sampling (RDS), a peer-driven recruitment sampling strategy that results in a probability sample. (Salganik M, Heckathorn DD. Sampling and estimation in hidden populations using respondent-driven sampling. Sociol Method. 2004;34:193-239). This paper presents a comparison of RDS implementation, findings on network and recruitment characteristics, and lessons learned. Initiated with 13 to 15 seeds, approximately 200 IDUs were recruited within 8 weeks. Information resulting from RDS indicates that social network patterns from the two studies differ greatly. Female IDUs in Tirana had smaller network sizes than male IDUs, unlike in St. Petersburg where female IDUs had larger network sizes than male IDUs. Recruitment patterns in each country also differed by demographic categories. Recruitment analyses indicate that IDUs form socially distinct groups by sex in Tirana, whereas there was a greater degree of gender mixing patterns in St. Petersburg. RDS proved to be an effective means of surveying these hard-to-reach populations.

    2011-06-01

    Engagement in peer play is an important factor in young children’s adjustment as they make the transition to school. We evaluated individual differences in peer play within a sample of 58 children aged 4–5 years. Among boys, but not among girls, emotion understanding and verbal ability independently served as positive predictors of interactive peer play and negative predictors of disconnected play. Among girls, but not among boys, interactive peer play and socio-moral reasoning about peer conflict situations independently predicted sociometric most-like nominations. The results provide a foundation for further research on divergence in the early peer play of girls and boys.

    2011-02-01

    The present study sought to document an example of how childhood sexual abuse and attachment representation interact while contributing to the trait anxiety of nonoffending mothers following the disclosure of their daughters' sexual abuse. The study sample consisted of 57 ethnically diverse mothers of sexually abused girls aged 6 to 16 and 47 mothers of comparison girls who were matched with the abused girls on age, socioeconomic status, and family constellation. Results indicate that the mothers' representations of past attachment relationships with their own fathers were differentially related to their current attachment styles, depending on their daughters' childhood sexual abuse status. The representation of past attachment relationships with peers had both main and protective effects on the mothers' trait anxiety symptoms. The relevance of attachment perspectives to adjustment among these mothers and intergenerational process in childhood sexual abuse are discussed, and implications for future research and clinical practices are identified.

    1999-09-01

    An entertainment-education radio soap opera introduced in Tanzania in 1993 was evaluated by means of a field experimental design in which the radio program was broadcast by seven mainland stations of Radio Tanzania. An eighth station broadcast alternative programming from 1993 to 1995, its listenership serving as a comparison area in which contemporaneous changes in family planning adoption were measured. The soap opera was subsequently broadcast nationwide from 1995 to 1997. Data about the effects of the radio soap opera were gathered in five annual surveys of about 2,750 households in the comparison and the treatment areas and from a sample of new family planning adopters in 79 health clinics. The soap opera had strong behavioral effects on family planning adoption; it increased listeners' self-efficacy regarding family planning adoption and influenced listeners to talk with their spouses and peers about contraception.

    Positive peer relationships are essential in healthy development. The prevalence of peer-relationship problems in children after acquired brain injury (ABI) has yet to be explored, although ABI does inevitably impact upon peer interactions. We aimed to explore how peer-relationships and emotional distress after ABI may differ from the levels reported by healthy children or mental health controls. Parents of 214 children (137 "healthy" children, 27 children using mental health services and 40 children with ABI) aged 9-15 years participated. A questionnaire measure of peer-relationship functioning and emotional distress was completed. Children with ABI experienced a greater degree of peer-relationship difficulties and emotional distress than healthy controls. No difference was found in reported peer relationship difficulties or emotional distress between ABI children and the children accessing mental health services. We conclude that emotional distress and co-occurring peer-relationship difficulties are as prevalent in a population of children after ABI as may be expected in a population of children under the care of mental health services, yet, unlike the latter group, appropriate intervention services are not commonly available. Interventions that aim to enhance peer relationships after childhood ABI may provide an essential resource to the benefit of outcome.

    The current study investigated the association between non-suicidal self-injury (NSSI), self-concept and acquaintance with NSSI peers in a sample of 150 high school students (60% female) with a mean age of 15.56 (SD=2.00) years. Analyses showed that students with NSSI rated themselves lower on academic intelligence, physical attractiveness, social skills and emotional stability than their non-NSSI peers. The self-injurers also had more friends who engaged in NSSI, and having more NSSI acquaintances was negatively related to self-esteem. It could be that adolescents with lower self-esteem are more attracted to self-injuring peers, or that adolescents with low self-esteem are more vulnerable to copy NSSI to deal with their problems or to gain a certain identity in their peer group. Future studies must test these possible NSSI pathways.

  10. Gossip-Based Dissemination

    Friedman, Roy; Kermarrec, Anne-Marie; Miranda, Hugo; Rodrigues, Luís

    Gossip-based networking has emerged as a viable approach to disseminate information reliably and efficiently in large-scale systems. Initially introduced for database replication [222], the applicability of the approach extends much further now. For example, it has been applied for data aggregation [415], peer sampling [416] and publish/subscribe systems [845]. Gossip-based protocols rely on a periodic peer-wise exchange of information in wired systems. By changing the way each peer is selected for the gossip communication, and which data are exchanged and processed [451], gossip systems can be used to perform different distributed tasks, such as, among others: overlay maintenance, distributed computation, and information dissemination (a collection of papers on gossip can be found in [451]). In a wired setting, the peer sampling service, allowing for a random or specific peer selection, is often provided as an independent service, able to operate independently from other gossip-based services [416].

  20. Increasing Persistence in Undergraduate Science Majors: A Model for Institutional Support of Underrepresented Students

    PubMed Central

    Toven-Lindsey, Brit; Levis-Fitzgerald, Marc; Barber, Paul H.; Hasson, Tama

    2015-01-01

    The 6-yr degree-completion rate of undergraduate science, technology, engineering, and mathematics (STEM) majors at U.S. colleges and universities is less than 40%. Persistence among women and underrepresented minorities (URMs), including African-American, Latino/a, Native American, and Pacific Islander students, is even more troubling, as these students leave STEM majors at significantly higher rates than their non-URM peers. This study utilizes a matched comparison group design to examine the academic achievement and persistence of students enrolled in the Program for Excellence in Education and Research in the Sciences (PEERS), an academic support program at the University of California, Los Angeles, for first- and second-year science majors from underrepresented backgrounds. Results indicate that PEERS students, on average, earned higher grades in most “gatekeeper” chemistry and math courses, had a higher cumulative grade point average, completed more science courses, and persisted in a science major at significantly higher rates than the comparison group. With its holistic approach focused on academics, counseling, creating a supportive community, and exposure to research, the PEERS program serves as an excellent model for universities interested in and committed to improving persistence of underrepresented science majors and closing the achievement gap.

    2015-01-01

    Although peer networks have been implicated as influential in a range of adolescent behaviors, little is known about relationships between peer network structures and risk for intimate partner violence (IPV) among youth. This study is a descriptive analysis of how peer network “types” may be related to subsequent risk for IPV perpetration among adolescents using data from 3,030 male respondents to the National Longitudinal Study of Adolescent Health. Sampled youth were a mean of 16 years of age when surveyed about the nature of their peer networks, and 21.9 when asked to report about IPV perpetration in their adolescent and early adulthood relationships. A latent class analysis of the size, structure, gender composition and delinquency level of friendship groups identified four unique profiles of peer network structures. Men in the group type characterized by small, dense, mostly male peer networks with higher levels of delinquent behavior reported higher rates of subsequent IPV perpetration than men whose adolescent network type was characterized by large, loosely connected groups of less delinquent male and female friends. Other factors known to be antecedents and correlates of IPV perpetration varied in their distribution across the peer group types, suggesting that different configurations of risk for relationship aggression can be found across peer networks. Implications for prevention programming and future research are addressed. PMID:20422351

    2016-08-01

    This study explored the contribution of peer-assisted learning (PAL) in the development of evaluative judgement capacity; the ability to understand work quality and apply those standards to appraising performance. The study employed a mixed methods approach, collecting self-reported survey data, observations of, and reflective interviews with, the medical students observed. Participants were in their first year of clinical placements. Data were thematically analysed. Students indicated that PAL contributed to both the comprehension of notions of quality, and the practice of making comparisons between a given performance and the standards. Emergent themes included peer story-telling, direct observation of performance, and peer-based feedback, all of which helped students to define 'work quality'. By participating in PAL, students were required to make comparisons, therefore using the standards of practice and gaining a deeper understanding of them. The data revealed tensions in that peers were seen as less threatening than supervisors with the advantage of increasing learners' appetites for thoughtful 'intellectual risk taking'. Despite this reported advantage of peer engagement, learners still expressed a preference for feedback from senior teachers as more trusted sources of clinical knowledge. While this study suggests that PAL already contributes to the development of evaluative judgement, further steps could be taken to formalise PAL in clinical placements to improve learners' capacity to make accurate judgements on the performance of self and others. Further experimental studies are necessary to confirm the best methods of using PAL to develop evaluative judgement. This may include both students and educators as instigators of PAL in the workplace.

    2014-11-01

    Although a relation between disaster exposure and ataques de nervios ( ataques ) has been established in adult samples, little is known about this among youth, including factors that may moderate this relation. This study examined the role of the peer context in the relation between exposure to Hurricane Georges and experiencing a past year and lifetime ataques among a representative community sample of 905 youth (N = 476 boys and 429 girls; ages 11-18) residing in Puerto Rico. Data were gathered from 1999-2000 in Puerto Rico, 12-27 months following Hurricane Georges. Logistic regression analyses found that peer violence significantly predicted experiencing an ataque in the past year. Hurricane exposure and peer violence were both significant predictors of a lifetime experience of an ataque . An interaction was found between hurricane exposure and peer violence, indicating that hurricane exposure was significantly related to a lifetime experience of an ataque among adolescents who do not report associating with violent peers. For participants reporting high levels of peer violence, hurricane exposure did not add additional risk for a lifetime experience of an ataque . Understanding the influence of peers in the relation between hurricane exposure and experiencing an ataque may assist in planning developmentally and culturally sensitive response plans.

    2016-11-01

    Many published research studies document item calibration invariance across samples using Rasch's probabilistic models for measurement. A new approach to outcomes evaluation for very small samples was employed for two workshop series focused on stress reduction and joyful living conducted for health system employees and caregivers since 2012. Rasch-calibrated self-report instruments measuring depression, anxiety and stress, and the joyful living effects of mindfulness behaviors were identified in peer-reviewed journal articles. Items from one instrument were modified for use with a US population, other items were simplified, and some new items were written. Participants provided ratings of their depression, anxiety and stress, and the effects of their mindfulness behaviors before and after each workshop series. The numbers of participants providing both pre- and post-workshop data were low (16 and 14). Analysis of these small data sets produce results showing that, with some exceptions, the item hierarchies defining the constructs retained the same invariant profiles they had exhibited in the published research (correlations (not disattenuated) range from 0.85 to 0.96). In addition, comparisons of the pre- and post-workshop measures for the three constructs showed substantively and statistically significant changes. Implications for program evaluation comparisons, quality improvement efforts, and the organization of communications concerning outcomes in clinical fields are explored.

    2015-10-01

    To review systematically studies examining the development of social competence in children born very preterm (VPT) (gestation <33 wks) and identify neonatal and family predictors. Peer-reviewed original articles were extracted from PubMed and PsycINFO following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Selection criteria included children born VPT and comparison children born at term, sample born after 1990, and children assessed between 0 and 17 years on at least one measure of social competence spanning social adjustment, performance, and/or social skills. Twenty-three studies were included. Seven focused on social competence and another 16 examined social competence within a range of outcomes. Study quality was low. Limitations included reliance on single informant data, cross-sectional measurement, use of brief screening tools, absence of child or peer report, and no conceptual model. In terms of social adjustment, 16 out of 21 studies found children born VPT had more peer problems and social withdrawal. Findings of social performance were mixed, with some studies suggesting differences in prosocial behavior (4/14) and others not. Social skills were assessed in four studies and showed children born VPT had poorer skills than children born at term. Predictors of social competence included gestational age, neonatal brain abnormalities, and family socio-economic status. Children born VPT have poorer social competence. These difficulties emerge early and persist throughout childhood. © 2015 Mac Keith Press.

    To evaluate the content and construct validity of the existing PROMIS Pediatric Parent-Proxy Peer Relationships Measure in 5- to 12-year-old children with autism spectrum disorder (ASD). Parents of 121 children aged 5 to 12 years who met DSM-IV criteria for ASD completed the Peer Relationships Measure using computerized adaptive testing (CAT). Parents also completed the Social Responsiveness Scale, Second Edition (SRS-2) and a demographic form. Intelligence quotient test results were extracted from clinical or research records. Five parents participated in semi-structured interviews about their child's peer relationships and the item content on the Peer Relationships Measure. The children in the sample were primarily male (87%). The sample was racially and ethnically diverse, and parents were predominantly highly educated. The mean T-score (SD) on the Peer Relationships Measure was 36 (8), with a range from 15 to 62. For 98% of subjects, the CAT required administration of 5 items to reach a standard error of measurement of less than 4 T-score units. The Peer Relationships Measure demonstrated a large correlation with the SRS-2 (r = -0.60, p < .0001). In semi-structured interviews, parents reported that the items on the Peer Relationships Measure were relevant to the peer relationships of their child with ASD, but they reported a few challenges related to variability in their children's peer relationships over time and to somewhat limited knowledge of relationships in school. The PROMIS Pediatric Parent-Proxy Peer Relationships Measure may be an efficient, precise, and valid measure of peer relationships for 5- to 12-year-old children with ASD.

    2016-07-27

    Despite the prevalence of the phenomena of peer victimization and bystander behaviors, little data has generated to describe their relationships and risk factors. In this paper, a self-administered survey using a cross-sectional cluster-random sampling method in a sample of 5450 participants (2734 girls and 2716 boys) between 4th and 11th grades was conducted at six schools (two primary schools and four middle schools) located in Shantou, China. Self-reported peer victimization, bystander behaviors and information regarding parents' risky behaviors and individual behavioral factors were collected. Multinomial logistic regression analysis was applied to evaluate risk factors affecting peer victimization and bystander behaviors. The results indicated that urban participants were more likely to become bullying victims but less likely to become passive bystanders. Contrarily, bullying victimization was related to the increasing of passive bystander behaviors. Father drinking and mother smoking as independent factors were risk factors for peer victimization. Participants who were smoking or drinking had a tendency to be involved in both peer victimization and passive bystander behaviors. This study suggested that bystander behaviors, victims' and parents' educations play a more important role in peer victimization than previously thought.

    2016-01-01

    The purpose of the current investigation was to examine the role of emotion regulation in the link between peer factors and adolescent adjustment difficulties. The sample consisted of 206 adolescents (ages 10–18 years) and parents. Peer factors (i.e., peer antisocial behavior, peer co-rumination, peer emotion regulation) and youth depressive symptoms were based on youth reports. Youth emotion regulation and antisocial behavior were assessed using parent and youth ratings. Results showed that peer antisocial behavior was directly (but not indirectly) related to youth antisocial behavior and depressive symptoms, whereas peer emotion regulation was indirectly (but not directly) related to both adolescent outcomes. In addition, peer co-rumination was indirectly related to youth antisocial behavior and directly and indirectly related to youth depressive symptoms. In general, the results indicated little evidence of moderation by adolescent age, sex, or ethnic differences. Implications for peer relationships as socialization contexts are discussed.

    Youths with chronic pain may experience difficulties with peer relationships. We investigated the quality and correlates of peer relationships in a sample of 181 youths with chronic pain. A majority of youths were satisfied with their relationships with peers; however, levels were highly variable. Higher functional impairment and depression levels predicted lower peer relationship quality, controlling for demographic and other pain-related factors. In addition, peer relationship quality and pain severity predicted child depression and anxiety symptoms, whereas peer relationship quality only predicted anger symptoms. Relationship quality moderated the association between pain severity and functional impairment, suggesting that strong relationships with peers may buffer the effects of pain on functioning. Peer relationships seem particularly important for the adjustment and psychological well-being of youths with chronic pain. Particular attention should be given to functionally impaired and depressed children, who may be at higher risk of peer difficulties.

    2005-09-01

    Although social comparison with media-portrayed thin-ideal images has been found to increase body dissatisfaction and negative affect, research has not yet tested whether social comparison with attractive peers in the real world produces similar effects. We randomly assigned 119 young women to interact either with a confederate who conformed to the thin ideal or one who conformed to the average body dimensions of women, within the context of an ostensive dating study. Exposure to the thin-ideal confederate resulted in an increase in body dissatisfaction but not negative affect or heart rate. Initial thin-ideal internalization, perceived sociocultural pressure, self-esteem, and observer-rated attractiveness did not moderate these effects. Results suggest that social comparative pressure to be thin fosters body dissatisfaction but may not promote negative affect. 2005 by Wiley Periodicals, Inc.

    2013-06-01

    This study investigates self-rated mental health in terms of psychological problems, protective factors and health-related quality of life (HRQOL) in a nationally representative sample of adolescents (n=6813) aged 11-17 involved in violence with varying frequency. Using MANCOVA and ANCOVA, youth with single and multiple histories of violent victimisation and violence perpetration were contrasted with non-involved comparisons. The results show that even low levels of violence involvement were associated with more problems, fewer protective factors and impaired HRQOL. Multiply victimised youth - not perpetrating victims - stood out with internalising, peer and hyperactivity/inattention problems. Discriminant function analysis separated non-involved from violence-affected youth, and multiply victimised from not multiply victimised youth. Externalising behaviours, family issues, male sex and school functioning predicted group separation on the first function (proportion variance explained 80.0%), while internalising and peer issues were predictive for the second function (PVE 14.2%). Implications for prevention, intervention and research are discussed. Copyright © 2013 The Foundation for Professionals in Services for Adolescents. Published by Elsevier Ltd. All rights reserved.

    Bullying is a widespread public health problem among school students. Using a large sample of Macanese school adolescents, the present study examines psychosocial conditions and demographic characteristics in discriminating the following four subgroups of students: victims; bullies; bully-victims; and a comparison group of adolescents. Participants included 2288 adolescents from 13 primary and secondary schools in Macau whose ages ranged from 10 to 20 years. Statistical results revealed significant differences among the groups and indicated that adolescents who are involved in school bullying experience worse psychosocial adjustment. Specifically, among the four subgroups of students, bully-victims reported the strongest feelings of anxiety, depression, and negative affectivity, and expressed the lowest satisfaction with life. Compared with students who were not involved in bullying and victimization, bullies experienced more anxiety and depression and victims had lower levels of satisfaction with life. In addition, boys were more likely to engage in bullying behaviors and younger students had a greater probability of being victimized by their peers at school. Implications for future research and practice on bullying perpetration and the prevention of peer victimization are discussed.

    2017-12-01

    Social media appear to contribute to body dissatisfaction in adolescents, although few empirical studies exist. This study used six focus groups (total N=38) to explore relations between social media use and body image in early adolescent girls (ages 12-14). Thematic analysis identified patterns in the data. In this sample, social media use was high. Girls endorsed some appearance concerns and social comparison, particularly with peers. However, they displayed high media literacy, appreciation of differences, and confidence, strategies that appeared helpful in mitigating the potential negative association between social media exposure and body image. Girls reported these characteristics were nurtured by positive parental influence and a supportive school environment. Results support an ecological approach to the prevention of body dissatisfaction. Although peer influence strengthens throughout adolescence, current findings suggest that parents and the school environment are associated with girls' attitudes and behaviors regarding social media and body image.

    The present study investigated the self-concept of deaf and hard-of-hearing (DHH) students in different educational settings compared with those of hearing students in Ethiopia. The research involved a sample of 103 Grade 4 students selected from 7 towns in Ethiopia. They were selected from a special school for the deaf, a special class for the deaf, and a regular school. The Self-Description Questionnaire I (Marsh, 1990) was used to measure the children's self-concept. The study results indicated that, in comparison with their hearing peers, DHH students had a lower self-concept in the areas of general self, general school, reading, and parental relations. The DHH students in the special school showed a higher self-concept in regard to their physical appearance than the hearing and DHH students in the special class. There were no statistically significant differences between the groups in the self-concept dimensions of peer relations, mathematics, and physical abilities. © The Author 2016.

    2016-08-01

    This study reports on a meta-analysis to examine how bilingual learners compare with English monolingual learners on two English spelling outcomes: real-word spelling and pseudo-word spelling. Eighteen studies published in peer-reviewed journals between 1990 and 2014 were retrieved. The study-level variables and characteristics (e.g. sample size, study design and research instruments) were coded, and 29 independent effect sizes across the 18 retrieved studies were analysed. We found that bilinguals outperformed monolinguals on real-word spelling overall and more so in early grades, but monolinguals outperformed bilinguals on pseudo-word spelling. Further, bilinguals at risk for reading difficulties did better on real-word spelling than monolinguals at risk for reading difficulties. Having investigated systematic sources of variability in effect sizes, we conclude that in comparison with their monolingual peers, bilingual learners, especially those from alphabetic L1 backgrounds, are able to master constrained skills, such as English spelling, in the current instructional context.

    2014-07-01

    A majority of peer victimization research focuses on its associations with negative outcomes, yet efforts to understand possible protective factors that may mitigate these negative outcomes also require attention. The present study was an investigation of the potential moderating effect of prosocial behaviors on loneliness for youth who are peer victimized. Participants were fourth and fifth grade students (511 total; 49 % boys) who were primarily European American (43.4 %) and Hispanic (48.2 %). Structural Equation Modeling was used to test the interaction of prosocial behavior and peer victimization (relational and overt forms) on loneliness 1 year later. The results indicated that prosocial behavior significantly moderated the relationship between peer victimization (for the relational form only) and loneliness while controlling for levels of perceived peer support. A multi-group comparison by gender further indicated the moderation was significant for boys only. Potential implications for intervention/prevention efforts focused on developing children's prosocial skills as a possible protective factor for relationally victimized youth are discussed.

  6. Attractive celebrity and peer images on Instagram: Effect on women's mood and body image.

    2016-12-01

    A large body of research has documented that exposure to images of thin fashion models contributes to women's body dissatisfaction. The present study aimed to experimentally investigate the impact of attractive celebrity and peer images on women's body image. Participants were 138 female undergraduate students who were randomly assigned to view either a set of celebrity images, a set of equally attractive unknown peer images, or a control set of travel images. All images were sourced from public Instagram profiles. Results showed that exposure to celebrity and peer images increased negative mood and body dissatisfaction relative to travel images, with no significant difference between celebrity and peer images. This effect was mediated by state appearance comparison. In addition, celebrity worship moderated an increased effect of celebrity images on body dissatisfaction. It was concluded that exposure to attractive celebrity and peer images can be detrimental to women's body image. Copyright © 2016 Elsevier Ltd. All rights reserved.

  7. School transitions, peer influence, and educational expectation formation: Girls and boys.

    2017-01-01

    School transitions are a regular feature of the educational career. While they are of general interest as instances of academic change, they also represent instances of peer environment and influence change. Previous theoretical and empirical work suggests peer influence is important for students' academic and educational outcomes, especially for the complex decision-making processes leading up to those outcomes. In this manuscript, we study the impact of peers on educational expectation formation at the 8th-to-9th-grade school transition. In doing so, we test a theoretical model that links institutional settings, social influence, and individual decision-making. We find the 9th grade transition likely represents a negative shock for students' college attendance expectations. Independent of this transition, however, stable peer environments further depress expectations. A more equal mixture of new and old peers in the 9th grade likely increases students' educational expectations in contrast. These effects of peer perturbations and the re-organization of social ties they imply mainly apply to female students. But, both male and female students revise their educational expectations in light of changing peer intelligence comparisons, albeit in countervailing ways. Copyright © 2016.

    To explore the co-evolution of friendship tie choice and alcohol use behavior among 1,284 adolescents from 12 small schools and 976 adolescents from one big school sampled in the National Longitudinal Study of Adolescent to Adult Health (AddHealth), we apply a Stochastic Actor-Based (SAB) approach implemented in the R-based Simulation Investigation for Empirical Network Analysis (RSiena) package. Our results indicate the salience of both peer selection and peer influence effects for friendship tie choice and adolescent drinking behavior. Concurrently, the main effect models indicate that parental monitoring and the parental home drinking environment affected adolescent alcohol use in the small school sample, and that parental home drinking environment affected adolescent drinking in the large school sample. In the small school sample, we detect an interaction between the parental home drinking environment and choosing friends that drink as they multiplicatively affect friendship tie choice. Our findings suggest that future research should investigate the synergistic effects of both peer and parental influences for adolescent friendship tie choices and drinking behavior. And given the tendency of adolescents to form ties with their friends' friends, and the evidence of local hierarchy in these networks, popular youth who do not drink may be uniquely positioned and uniquely salient as the highest rank of the hierarchy to cause anti-drinking peer influences to diffuse down the social hierarchy to less popular youth. As such, future interventions should harness prosocial peer influences simultaneously with strategies to increase parental support and monitoring among parents to promote affiliation with prosocial peers.

    Cyber victimization is an important research area; yet, little is known about aversive peer experiences on social networking sites (SNSs), which are used extensively by youth and host complex social exchanges. Across samples of adolescents ( n =216) and young adults ( n =214), we developed the Social Networking-Peer Experiences Questionnaire ( SN-PEQ ), and examined its psychometric properties, distinctiveness from traditional peer victimization, and associations with internalized distress. The SN-PEQ demonstrated strong factorial invariance and a single factor structure that was distinct from other forms of peer victimization. Negative SNS experiences were associated with youths' symptoms of social anxiety and depression, even when controlling for traditional peer victimization. Findings highlight the importance of examining the effects of aversive peer experiences that occur via social media.

    In medical education, student distress is known to hamper learning and professional development. To address this problem, recent studies aimed at helping students cope with stressful situations. Undergraduate students in clinical practice frequently use experiences of surrounding peers to estimate their abilities to master such challenging situations. This use of the experiences of others, known as social comparison, may affect student distress both positively and negatively. To find characteristics of a beneficial use of social comparison, we examined differences in comparison behaviours between students expressing low and high levels of distress. The participants in our study, response rate 93% (N = 301/321), were all medical students in their first year in clinical practice. They completed the General Health Questionnaire (GHQ-12) to measure distress, and three separate questionnaires to measure: (1) orientation to comparison, (2) motive for comparison, and (3) interpretation of comparison. Differences were analysed using multivariate analysis of variance. Although all students were oriented towards social comparison, the analyses showed that this orientation was less apparent among low-distress students. Besides, the low-distress students were less inclined to use motives indicative for comparisons with peers perceived as performing worse and were less negative in the interpretations of their comparisons. As social comparison is frequently used among all students, we recommend to make them aware of their comparison behaviours and inform them about the pros and cons of the distinguished aspects of the comparison process.

    Emerging adulthood often entails heightened risk-taking with potential life-long consequences, and research on risk behaviors is needed to guide prevention programming, particularly in under-served and difficult to reach populations. This study evaluated the utility of Respondent Driven Sampling (RDS), a peer-driven methodology that corrects limitations of snowball sampling, to reach at-risk African American emerging adults from disadvantaged urban communities. Initial "seed" participants from the target group recruited peers, who then recruited their peers in an iterative process (110 males, 234 females; M age = 18.86 years). Structured field interviews assessed common health risk factors, including substance use, overweight/obesity, and sexual behaviors. Established gender-and age-related associations with risk factors were replicated, and sample risk profiles and prevalence estimates compared favorably with matched samples from representative U.S. national surveys. Findings supported the use of RDS as a sampling method and grassroots platform for research and prevention with community-dwelling risk groups.

  12. Defining body deception and its role in peer based social comparison theories of body dissatisfaction.

    2008-09-01

    The purpose of the current study was to operationalize the phenomenon of body deception, describe its theoretical importance, and validate its existence in an experimental paradigm. The definition of body deception includes the intentional misrepresentation of information about appearance to others. The present study examined body deception in a controlled experimental study of male and female same-sex peer groups using a series of hierarchical linear models. Ninety male and 90 female undergraduates were randomized to an experimental same-sex peer group or individual control condition. The results suggested that both men and women used body deception among peers, but men's body deception was muscularity driven whereas women's was thinness driven. Body dissatisfaction was significantly predictive of the degree of body deception used by both genders and it was significantly related to peer group membership. An integrated model for the role of body deception in body image disturbance is proposed.

  8. Peer Support for the Hardly Reached: A Systematic Review.

    PubMed

    Sokol, Rebeccah; Fisher, Edwin

    2016-07-01

    Health disparities are aggravated when prevention and care initiatives fail to reach those they are intended to help. Groups can be classified as hardly reached according to a variety of circumstances that fall into 3 domains: individual (e.g., psychological factors), demographic (e.g., socioeconomic status), and cultural-environmental (e.g., social network). Several reports have indicated that peer support is an effective means of reaching hardly reached individuals. However, no review has explored peer support effectiveness in relation to the circumstances associated with being hardly reached or across diverse health problems. To conduct a systematic review assessing the reach and effectiveness of peer support among hardly reached individuals, as well as peer support strategies used. Three systematic searches conducted in PubMed identified studies that evaluated peer support programs among hardly reached individuals. In aggregate, the searches covered articles published from 2000 to 2015. Eligible interventions provided ongoing support for complex health behaviors, including prioritization of hardly reached populations, assistance in applying behavior change plans, and social-emotional support directed toward disease management or quality of life. Studies were excluded if they addressed temporally isolated behaviors, were limited to protocol group classes, included peer support as the dependent variable, did not include statistical tests of significance, or incorporated comparison conditions that provided appreciable social support. We abstracted data regarding the primary health topic, categorizations of hardly reached groups, program reach, outcomes, and strategies employed. We conducted a 2-sample t test to determine whether reported strategies were related to reach. Forty-seven studies met our inclusion criteria, and these studies represented each of the 3 domains of circumstances assessed (individual, demographic, and cultural-environmental). Interventions addressed 8 health areas, most commonly maternal and child health (25.5%), diabetes (17.0%), and other chronic diseases (14.9%). Thirty-six studies (76.6%) assessed program reach, which ranged from 24% to 79% of the study population. Forty-four studies (94%) reported significant changes favoring peer support. Eleven strategies emerged for engaging and retaining hardly reached individuals. Among them, programs that reported a strategy of trust and respect had higher participant retention (82.8%) than did programs not reporting such a strategy (48.1%; P = .003). In 5 of the 6 studies examining moderators of the effects of peer support, peer support benefits were greater among individuals characterized by disadvantage (e.g., low health literacy). Peer support is a broad and robust strategy for reaching groups that health services too often fail to engage. The wide range of audiences and health concerns among which peer support is successful suggests that a basis for its success may be its flexible response to different contexts, including the intended audience, health problems, and setting. The general benefits of peer support and findings suggesting that it may be more effective among those at heightened disadvantage indicate that peer support should be considered in programs intended to reach and benefit those too often hardly reached. Because engendering trust and respect was significantly associated with participant retention, programs should emphasize this strategy.

  9. Initial sociometric impressions of attention-deficit hyperactivity disorder and comparison boys: predictions from social behaviors and from nonbehavioral variables.

    Erhardt, Drew; Hinshaw, Stephen P

    1994-08-01

    This study systematically compared the influence of naturalistic social behaviors and nonbehavioral variables on the development of peer status in 49 previously unfamiliar boys, aged 6-12 years, who attended a summer research program. Twenty-five boys with attention-deficit hyperactivity disorder (ADHD) and 24 comparison boys participated. Physical attractiveness, motor competence, intelligence, and academic achievement constituted the nonbehavioral variables; social behaviors included noncompliance, aggression, prosocial actions, and isolation, measured by live observations of classroom and playground interactions. As early as the first day of interaction, ADHD and comparison boys displayed clear differences in social behaviors, and the ADHD youngsters were overwhelmingly rejected. Whereas prosocial behavior independently predicted friendship ratings during the first week, the magnitude of prediction was small. In contrast, the boys' aggression (or noncompliance) strongly predicted negative nominations, even with nonbehavioral factors, group status (ADHD versus comparison), and other social behaviors controlled statistically. Implications for understanding and remediating negative peer reputations are discussed.

    2014-01-01

    Purpose To examine how prenatal heroin/cocaine exposure (PDE) and behavioral problems relate to adolescent drug experimentation. Methods The sample included African American adolescents (mean age=14.2 yr, SD=1.2) with PDE (n=73) and a non-exposed community comparison (n=61). PDE status was determined at delivery through toxicology analysis and maternal-report. Internalizing/externalizing problems were assessed during adolescence with the Behavior Assessment System for Children, Second Edition. Drug experimentation was assessed by adolescent-report and urine analysis. Logistic regression evaluated the likelihood of drug experimentation related to PDE and behavioral problems, adjusting for age, gender, prenatal tobacco/alcohol exposure, perceived peer drug use and caregiver drug use. Interaction terms examined gender modification. Results 67 (50%) used drugs. 25 (19%) used tobacco/alcohol only and 42 (31%) used marijuana/illegal drugs. 94 (70%) perceived peer drug use. PDE significantly increased the risk of tobacco/alcohol experimentation (OR=3.07, 95% CI: 1.09–8.66, p=0.034), but not after covariate adjustment (aOR=1.31, 95% CI: 0.39–4.36, p>0.05). PDE was not related to overall or marijuana/illegal drug experimentation. The likelihood of overall drug experimentation was doubled per Standard Deviation (SD) increase in externalizing problems (aOR=2.28, 95% CI: 1.33–3.91, p=0.003) and, among girls, 2.82 times greater (aOR=2.82, 95% CI: 1.34–5.94, p=0.006) per SD increase in internalizing problems. Age and perceived peer drug use were significant covariates. Conclusions Drug experimentation was relatively common (50%), especially in the context of externalizing problems, internalizing problems (girls only), age, and perceived peer drug use. Findings support Problem Behavior Theory and suggest that adolescent drug prevention address behavioral problems and promote prosocial peer groups. PMID:24768161

    Background While there is an increasing pool of literature documenting the benefits of near-peer tutoring programme, little is known about the benefits for junior and senior peer tutors. Knowledge of the peer tutors’ perceived benefits at different levels of seniority will aid in the development of a near-peer tutoring programme that will better fulfil both curricula and personal aspirations of near-peer tutors. We, therefore, investigated the perceived benefits of participation in a near-peer tutoring programme for junior as well as senior near-peer tutors. Methods Pre- and post-participation questionnaires were distributed to near-peer tutors after their clinical skills teaching sessions with Phase I undergraduate medical students. The Peer Tutor Assessment Instrument questionnaires were distributed to the 1) students, and to the 2) near-peer tutors (junior and senior) after each teaching and learning session for self-evaluation. Results The senior near-peer tutors felt that their participation in the programme had enhanced their skills (p=0.03). As a whole, the near-peer tutors were more motivated (Pre 5.32±0.46; Post 5.47±0.50; p=0.210) to participate in future teaching sessions but did not expect that having teaching experiences would make teaching as their major career path in the future (Pre 4.63±1.07; Post 4.54±0.98; p=0.701). The senior near-peer tutors were evaluated significantly higher by the students (p=0.0001). Students’ evaluations of near-peer tutors on the domain of critical analysis was higher than self-evaluations (p=0.003). Conclusions Generally, the near-peer tutors perceived that they have benefited most in their skills enhancement and these near-peer tutors were scored highly by the students. However, senior near-peer tutors do not perceive that the programme has a lasting impact on their choice of career path. PMID:26356229

    Background While there is an increasing pool of literature documenting the benefits of near-peer tutoring programme, little is known about the benefits for junior and senior peer tutors. Knowledge of the peer tutors' perceived benefits at different levels of seniority will aid in the development of a near-peer tutoring programme that will better fulfil both curricula and personal aspirations of near-peer tutors. We, therefore, investigated the perceived benefits of participation in a near-peer tutoring programme for junior as well as senior near-peer tutors. Methods Pre- and post-participation questionnaires were distributed to near-peer tutors after their clinical skills teaching sessions with Phase I undergraduate medical students. The Peer Tutor Assessment Instrument questionnaires were distributed to the 1) students, and to the 2) near-peer tutors (junior and senior) after each teaching and learning session for self-evaluation. Results The senior near-peer tutors felt that their participation in the programme had enhanced their skills (p=0.03). As a whole, the near-peer tutors were more motivated (Pre 5.32±0.46; Post 5.47±0.50; p=0.210) to participate in future teaching sessions but did not expect that having teaching experiences would make teaching as their major career path in the future (Pre 4.63±1.07; Post 4.54±0.98; p=0.701). The senior near-peer tutors were evaluated significantly higher by the students (p=0.0001). Students' evaluations of near-peer tutors on the domain of critical analysis was higher than self-evaluations (p=0.003). Conclusions Generally, the near-peer tutors perceived that they have benefited most in their skills enhancement and these near-peer tutors were scored highly by the students. However, senior near-peer tutors do not perceive that the programme has a lasting impact on their choice of career path.

    The supplementary comparison report APMP.RF-S21.F describes the comparison of loop antennas, which was conducted between April 2013 and January 2014. The two comparison artefacts were well-characterised active loop antennas of diameter 30 cm and 60 cm respectively, which typically operate in a frequency range from 9 kHz to 30 MHz. These antennas represent the main groups of antennas which are used around the world for EMC measurements in the frequency range below 30 MHz. There are several well-known methods for calibrating the antenna factor of these devices. The calibration systems used in this comparison for the loop antennas employed the standard magnetic field method or the three-antenna method. Despite the limitations of the algorithm, which we used to derive the reference value for each case (particularly for small samples), the actual calculated reference values seem to be reasonable. As a result, the agreement between each participant was very good in all cases. Main text To reach the main text of this paper, click on Final Report.

    Hydrostatic density determinations of liquids as reference material are mainly performed by National Metrology Institutes to provide means for calibrating or checking liquid density measuring instruments such as oscillation-type density meters. These density meters are used by most of the metrology institutes for their calibration and scientific work. The aim of this project was to compare the results of the liquid density determination by oscillating density meters of the participating laboratories. The results were linked to CCM.D.K-2 partly via Project EURAMET.M.D.K-2 (1019) "Comparison of liquid density standards" by hydrostatic weighing piloted by BEV in 2008. In this comparison pentadecane, water and of oil with a high viscosity were measured at atmospheric pressure using oscillation type density meter. The temperature range was from 15 °C to 40 °C. The measurement results were in some cases discrepant. Further studies, comparisons are essential to explore the capability and uncertainty of the density meters Main text To reach the main text of this paper, click on Final Report.

    The peer group begins to become a source of support during late childhood and adolescence making it important to understand what type of help young people might suggest to a friend with an emotional or behavioral problem. Three groups of young people participated in the study with average ages of 12 (N = 107), 14 (N = 153) and 16 years (N = 133). All participants were presented with vignettes describing fictional peers, two of whom had symptoms of clinical problems (ADHD and depression) and a third comparison peer without symptoms. Results indicate that all participants distinguished between clinical and comparison vignette characters and they believed that the characters with clinical symptoms needed help. The 16-year-olds were more likely to differentiate between the two clinical vignettes in terms of the type of help suggested. The results are discussed in light of previous research on adolescents' understanding of sources of help for mental health problems.

    Objective To investigate the effectiveness of open peer review as a mechanism to improve the reporting of randomised trials published in biomedical journals. Design Retrospective before and after study. Setting BioMed Central series medical journals. Sample 93 primary reports of randomised trials published in BMC-series medical journals in 2012. Main outcome measures Changes to the reporting of methodological aspects of randomised trials in manuscripts after peer review, based on the CONSORT checklist, corresponding peer reviewer reports, the type of changes requested, and the extent to which authors adhered to these requests. Results Of the 93 trial reports, 38% (n=35) did not describe the method of random sequence generation, 54% (n=50) concealment of allocation sequence, 50% (n=46) whether the study was blinded, 34% (n=32) the sample size calculation, 35% (n=33) specification of primary and secondary outcomes, 55% (n=51) results for the primary outcome, and 90% (n=84) details of the trial protocol. The number of changes between manuscript versions was relatively small; most involved adding new information or altering existing information. Most changes requested by peer reviewers had a positive impact on the reporting of the final manuscript—for example, adding or clarifying randomisation and blinding (n=27), sample size (n=15), primary and secondary outcomes (n=16), results for primary or secondary outcomes (n=14), and toning down conclusions to reflect the results (n=27). Some changes requested by peer reviewers, however, had a negative impact, such as adding additional unplanned analyses (n=15). Conclusion Peer reviewers fail to detect important deficiencies in reporting of the methods and results of randomised trials. The number of these changes requested by peer reviewers was relatively small. Although most had a positive impact, some were inappropriate and could have a negative impact on reporting in the final publication. PMID:24986891

    The purpose of the current study was to examine adolescents' perceptions of negative and positive peer influence (i.e., indirect peer association and direct peer pressure) as they related to adolescent behavior. Regression analyses were conducted using a sample of African American, European American, and Hispanic adolescents (N=1659, M age=16.06, SD=1.10). The study found differences and similarities in relation to respondents' ethnicity vis-à-vis indirect peer association and adolescent behavior. Although few ethnic-based differences occurred as a function of indirect negative peer association, indirect positive peer association was not as consistently or as strongly related to behaviors for minority youth as it was for European American youth.

    To make longitudinal comparisons of intelligence quotient (IQ) in children with cochlear implants (CIs) and typical hearing peers from early in development to the school-age period. Children with additional comorbidities and CIs were also evaluated. To estimate the impact of socioeconomic status and oral language on school-age cognitive performance. This longitudinal study evaluated nonverbal IQ in a multicenter, national sample of 147 children with CIs and 75 typically hearing peers. IQ was evaluated at baseline, prior to cochlear implantation, using the Bayley Scales of Infant and Toddler Development and the Leiter International Performance Scale. School-age IQ was assessed using the Wechsler Intelligence Scales for Children. For the current study, only the Perceptual Reasoning and Processing Speed indices were administered. Oral language was evaluated using the Comprehensive Assessment of Spoken Language. Children in the CI group scored within the normal range of intelligence at both time points. However, children with additional comorbidities scored significantly worse on the Processing Speed, but not the Perceptual Reasoning Index. Maternal education and language were significantly related to school-age IQ in both groups. Importantly, language was the strongest predictor of intellectual functioning in both children with CIs and normal hearing. These results suggest that children using cochlear implants perform similarly to hearing peers on measures of intelligence, but those with severe comorbidities are at-risk for cognitive deficits. Despite the strong link between socioeconomic status and intelligence, this association was no longer significant once spoken language performance was accounted for. These results reveal the important contributions that early intervention programs, which emphasize language and parent training, contribute to cognitive functioning in school-age children with CIs. For families from economically disadvantaged backgrounds, who are at-risk for suboptimal outcomes, these early intervention programs are critical to improve overall functioning.

    Two competing hypotheses were tested concerning the associations between current alcohol and cigarette use and measures of individual, group and network peer standing in an ethnically-diverse sample of 156 male and female adolescents sampled at two time points in the seventh grade. Findings lent greater support to the person hypothesis, with early regular substance users enjoying elevated standing amongst their peers and maintaining this standing regardless of their maintenance of or desistance from current use later in the school year. In the fall semester, users (n=20, 13%) had greater social impact, were described by their peers as more popular, and were more central to the peer network than abstainers (i.e., those who did not report current use). Conversely, in the spring semester, there were no differences between users (n=22, 13%) and abstainers in peer ratings of popularity or social impact. Notably, the spring semester users group retained fewer than half of the users from the fall semester. Further, students who had reported current use in the fall, as a group, retained their positions of elevated peer standing in the spring, compared to all other students, and continued to be rated by their peers as more popular and as having greater social impact. We discuss the findings in terms of the benefit of employing simultaneous systemic and individual measures of peer standing or group prominence, which in the case of peer-based prevention programs, can help clarify the truly influential from the “pretenders” in the case of diffusion of risk-related behaviors.

    The present study examines how the composition of social networks and perceived relationship content influence peer clustering in smoking, and how the association changes during the transition from late adolescence to early adulthood. The analysis was based on a Swedish two-wave survey sample comprising ego-centric network data. Respondents were 19 years old in the initial wave, and 23 when the follow-up sample was conducted. 17,227 ego-alter dyads were included in the analyses, which corresponds to an average response rate of 48.7 percent. Random effects logistic regression models were performed to calculate gender-specific average marginal effects of social network characteristics on smoking. The association of egos' and alters' smoking behavior was confirmed and found to be stronger when correlated in the female sample. For females, the associations decreased between age 19 and 23. Interactions between network characteristics and peer clustering in smoking showed that intense social interactions with smokers increase egos' smoking probability. The influence of network structures on peer clustering in smoking decreased during the transition from late adolescence to early adulthood. The study confirmed peer clustering in smoking and revealed that females' smoking behavior in particular is determined by social interactions. Female smokers' propensity to interact with other smokers was found to be associated with the quality of peer relationships, frequent social interactions, and network density. The influence of social networks on peer clustering in smoking decreased during the transition from late adolescence to early adulthood.

    The current study investigated the moderating effect of peer networks on neighborhood disorder's association with substance use in a sample of primarily African American urban adolescents. A convenience sample of 248 adolescents was recruited from urban health care settings and followed for two years, assessing psychological, social, and geographic risk and protective characteristics. A subset of 106 substance using participants were used for the analyses. A moderation model was tested to determine if the influence of neighborhood disorder (percent vacant housing, assault index, percent single parent headed households, percent home owner occupied, percent below poverty line) on substance use was moderated by peer network health (sum of peer risk and protective behaviors). Evidence for hypothesized peer network moderation was supported. A latent growth model found that peer network health is most strongly associated with lower baseline substance use for young adolescents residing in more disordered neighborhoods. Over the course of two years (ages approximately 14-16) this protective effect declines, and the decline is stronger for more disordered neighborhoods. Understanding the longitudinal moderating effects of peer networks within high-risk urban settings is important to the development and testing of contextually sensitive peer-based interventions. suggest that targeting the potential protective qualities of peer networks may be a promising approach for interventions seeking to reduce substance use, particularly among younger urban adolescents living in high-risk neighborhoods.

    Peer providers are integral to Full Service Partnerships (FSPs), which are team-based mental health service models. Peer providers use principles of recovery to engage clients, but FSPs can vary in their recovery orientation. Whether and how peer recovery orientation reflects the organizational environments of FSPs is unclear. This qualitative study explored peer provider attitudes towards recovery within the organizational contexts of FSPs where they are employed. Case study analysis was conducted on eight purposively sampled FSPs using qualitative interviews with peer providers and program directors. In two cases, peer recovery attitudes diverged from those of their organizational context. In these cases, peer providers were champions for recovery, and used practice-based strategies to promote client autonomy despite working in settings with lower recovery orientation. Peer providers could be uniquely positioned to promote client autonomy in settings where organizational factors limit consumer choice.

    The beneficial effects of peer teaching in medical education have been well-described in the literature. However, it is unclear whether students prefer to be taught by peers in small or large group settings. This study's aim was to identify differences in medical students' preferences and perceptions of small-group versus large-group peer teaching. Questionnaires were administered to medical students in Year 3 and Year 4 (first 2 years of clinical training) at one institution in the United Kingdom to identify their experiences and perceptions of small-and large-group peer teaching. For this study, small-group peer teaching was defined as a tutorial, or similar, taught by peer tutor to a group of 5 students or less. Large-group peer teaching was defined as a lecture, or similar, taught by peer tutors to a group of more than 20 students. Seventy-three students (81% response rate) completed the questionnaires (54% males; median age of 23). Nearly 55% of respondents reported prior exposure to small-group peer teaching but a larger proportion of respondents (86%) had previously attended large-group peer teaching. Of all valid responses, 49% did not have a preference of peer teaching method while 47% preferred small-group peer teaching. The majority of Year 3 students preferred small-group peer teaching to no preference (62.5% vs 37.5%, Fisher's exact test; P = 0.035) whereas most Year 4 students did not report a particular preference. Likert-scale responses showed that the majority of students held negative perceptions about large-group peer teaching, in comparison with small-group peer teaching, with respect to (1) interactivity, (2) a comfortable environment to ask questions, and (3) feedback received. Most respondents in this study did not report a preference for small-versus large-group settings when taught by peers. More Year 3 respondents were likely to prefer small-group peer teaching as opposed to Year 4 respondents.

    Training of lay-rescuers is essential to improve survival-rates after cardiac arrest. Multiple campaigns emphasise the importance of basic life support (BLS) training for school children. Trainings require a valid assessment to give feedback to school children and to compare the outcomes of different training formats. Considering these requirements, we developed an assessment of BLS skills using MiniAnne and tested the inter-rater reliability between professionals, medical students and trained school children as assessors. Fifteen professional assessors, 10 medical students and 111-trained school children (peers) assessed 1087 school children at the end of a CPR-training event using the new assessment format. Analyses of inter-rater reliability (intraclass correlation coefficient; ICC) were performed. Overall inter-rater reliability of the summative assessment was high (ICC = 0.84, 95 %-CI: 0.84 to 0.86, n = 889). The number of comparisons between peer-peer assessors (n = 303), peer-professional assessors (n = 339), and peer-student assessors (n = 191) was adequate to demonstrate high inter-rater reliability between peer- and professional-assessors (ICC: 0.76), peer- and student-assessors (ICC: 0.88) and peer- and other peer-assessors (ICC: 0.91). Systematic variation in rating of specific items was observed for three items between professional- and peer-assessors. Using this assessment and integrating peers and medical students as assessors gives the opportunity to assess hands-on skills of school children with high reliability.

    Recent controversies highlighting substandard peer review in Open Access (OA) and traditional (subscription) journals have increased the need for authors, funders, publishers, and institutions to assure quality of peer-review in academic journals. I propose that transparency of the peer-review process may be seen as an indicator of the quality of peer-review, and develop and validate a tool enabling different stakeholders to assess transparency of the peer-review process. Based on editorial guidelines and best practices, I developed a 14-item tool to rate transparency of the peer-review process on the basis of journals' websites. In Study 1, a random sample of 231 authors of papers in 92 subscription journals in different fields rated transparency of the journals that published their work. Authors' ratings of the transparency were positively associated with quality of the peer-review process but unrelated to journal's impact factors. In Study 2, 20 experts on OA publishing assessed the transparency of established (non-OA) journals, OA journals categorized as being published by potential predatory publishers, and journals from the Directory of Open Access Journals (DOAJ). Results show high reliability across items (α = .91) and sufficient reliability across raters. Ratings differentiated the three types of journals well. In Study 3, academic librarians rated a random sample of 140 DOAJ journals and another 54 journals that had received a hoax paper written by Bohannon to test peer-review quality. Journals with higher transparency ratings were less likely to accept the flawed paper and showed higher impact as measured by the h5 index from Google Scholar. The tool to assess transparency of the peer-review process at academic journals shows promising reliability and validity. The transparency of the peer-review process can be seen as an indicator of peer-review quality allowing the tool to be used to predict academic quality in new journals.

    We investigated the specificity of social difficulties to social anxiety by testing associations of social anxiety and other anxiety presentations with peer acceptance and victimization in community and treatment-seeking samples of adolescents aged 12-14 years. Cross-sectional, quantitative survey. Adolescents from the community (n = 116) and a clinical setting (n = 154) completed ratings of anxiety symptoms, perceived social acceptance, and peer victimization. Their parents also completed ratings of the adolescents' anxiety and social acceptance. Social acceptance was lowest among adolescents with social anxiety disorder (SAD) and lower among adolescents with other anxiety disorders than in the community sample. Anxiety symptoms were negatively correlated with social acceptance, but these associations were not unique to social anxiety symptoms. Girls in the community sample reported more overt victimization than girls with SAD and with other anxiety diagnoses. Relational victimization was associated with social and nonsocial anxiety symptoms only in the community sample. Our findings supplement recent laboratory-based observational studies on social functioning among adolescents with SAD and other anxiety disorders. Although social anxiety may be associated with unique social skill deficits and impairment, concerns about peer relations should also be considered among adolescents with other anxiety symptoms.

    Cyber victimization is an important research area; yet, little is known about aversive peer experiences on social networking sites (SNSs), which are used extensively by youth and host complex social exchanges. Across samples of adolescents (n=216) and young adults (n=214), we developed the Social Networking-Peer Experiences Questionnaire (SN-PEQ), and examined its psychometric properties, distinctiveness from traditional peer victimization, and associations with internalized distress. The SN-PEQ demonstrated strong factorial invariance and a single factor structure that was distinct from other forms of peer victimization. Negative SNS experiences were associated with youths’ symptoms of social anxiety and depression, even when controlling for traditional peer victimization. Findings highlight the importance of examining the effects of aversive peer experiences that occur via social media. PMID:24288449

    Many hearing-impaired students demonstrate difficulty in academically measuring up to their hearing peers. The deficiencies become especially obvious during their secondary school years. This study surveyed a national sample of elementary and secondary level teachers of the hearing impaired to compare their perceptions of the competencies needed to work with hearing-impaired students. The results suggest that teachers at both levels believe that some skills are fundamental for all teachers of the hearing-impaired, regardless of the age level of the students. However, the data also suggest there are some important differences. Concerns about state certification procedures and current practices in teacher training programs are discussed.

    2016-06-10

    The peer review process is a cornerstone of biomedical research. We aimed to evaluate the impact of interventions to improve the quality of peer review for biomedical publications. We performed a systematic review and meta-analysis. We searched CENTRAL, MEDLINE (PubMed), Embase, Cochrane Database of Systematic Reviews, and WHO ICTRP databases, for all randomized controlled trials (RCTs) evaluating the impact of interventions to improve the quality of peer review for biomedical publications. We selected 22 reports of randomized controlled trials, for 25 comparisons evaluating training interventions (n = 5), the addition of a statistical peer reviewer (n = 2), use of a checklist (n = 2), open peer review (i.e., peer reviewers informed that their identity would be revealed; n = 7), blinded peer review (i.e., peer reviewers blinded to author names and affiliation; n = 6) and other interventions to increase the speed of the peer review process (n = 3). Results from only seven RCTs were published since 2004. As compared with the standard peer review process, training did not improve the quality of the peer review report and use of a checklist did not improve the quality of the final manuscript. Adding a statistical peer review improved the quality of the final manuscript (standardized mean difference (SMD), 0.58; 95 % CI, 0.19 to 0.98). Open peer review improved the quality of the peer review report (SMD, 0.14; 95 % CI, 0.05 to 0.24), did not affect the time peer reviewers spent on the peer review (mean difference, 0.18; 95 % CI, -0.06 to 0.43), and decreased the rate of rejection (odds ratio, 0.56; 95 % CI, 0.33 to 0.94). Blinded peer review did not affect the quality of the peer review report or rejection rate. Interventions to increase the speed of the peer review process were too heterogeneous to allow for pooling the results. Despite the essential role of peer review, only a few interventions have been assessed in randomized controlled trials. Evidence-based peer review needs to be developed in biomedical journals.

    Students with physical symptoms and diseases may be at an increased risk of peer victimization. This study examined the associations of several medical conditions (obesity, asthma, allergy, epilepsy, and diabetes) with experience of physical, verbal, and relational victimization among children. A sample of 6,233 fourth-grade students from 314 elementary schools in Taiwan was recruited for the analysis. The mean age of the sample was 10.5, with an even distribution of gender (50.3% male and 49.7% female). Children with asthma, allergy, and epilepsy reported higher frequencies of peer victimization. Those who took daily medications or received treatment were also at a higher risk of being victimized. Diabetes and obesity were not found to be associated with peer victimization. The findings highlighted that children with physical conditions suffer maltreatment from peers. Sensitivity training should be provided to school health professionals, so they can evaluate the risk of victimization among students with special needs during assessment.

    2017-10-01

    The purpose of this study was to examine the role of aggressive behavior, anxiety, and peer rejection as multilevel indicators of peer victimization. A cross-sectional sample of 1,115 Finnish 9th grade students nested in 76 classrooms (mean age 15 years) were used to conduct multilevel models. All forms of psychosocial maladjustment, as well as student family economy, were found to predict peer victimization within classrooms. In addition, classrooms with more aggressive behavior and a higher proportion of rejected students suffered more peer victimization, beyond compositional effects of aggressive and rejected students being victimized.

    2010-01-01

    Purpose To apply a diathesis × stress model to testing the association between peer victimization and depression in a sample of preadolescent girls. Methods DSM-IV symptoms of depression symptoms were measured at ages 9 and 11, assertiveness and peer victimization were assessed by youth report at age 9. Results The interaction of low levels of assertiveness and high peer victimization at age 9 was predictive of depression symptoms at age 11, controlling for earlier depression symptoms. Conclusions The results extend the literature on peer relations and depression by identifying a group of girls who may be particularly vulnerable to the stress of negative peer interactions.

    2015-01-01

    Studies investigating the life satisfaction of intellectually gifted and non-gifted students are scarce and often suffer from methodological shortcomings. We examined the life satisfaction of gifted and non-gifted adolescents using a rather unselected sample of N = 655 German high-school students (n = 75 gifted), adequate comparison groups of non-gifted students, and a clear definition of giftedness (general intelligence g > 2 SD above the mean). There was no difference in life satisfaction between gifted and non-gifted adolescents (d < |0.1|). Girls reported somewhat lower life satisfaction scores than boys (d = 0.24). However, this result was not specific to giftedness but was instead found across the entire sample. Thus, gifted girls were not found to be especially unsatisfied with their lives. Our findings support previous research showing that giftedness is not a risk factor for impaired psycho-social well-being of boys or girls. PMID:26539152

    2016-03-01

    The current study used a behavioral genetic design to test whether three measures of pubertal timing moderated peer influence on risk-taking in a sample of 248 female adolescent twin pairs ( M age =16.0, SD =1.5) from the National Longitudinal Study of Adolescent Health. Peer influence was operationalized as the quasi-causal association between girls' self-reported risk-taking and the risk-taking reported by their friends. Girls with earlier ages at menarche and who perceived themselves as more developed than peers were more susceptible to peer influence on risk-taking. However, age-standardized ratings of body changes did not moderate peer influence. This study highlights distinctions between multiple measures of pubertal timing, using an innovative synthesis of genetically informative data and peer nomination data.

    2004-10-01

    Peer victimization is a common occurrence in school settings. This study investigated the relationship between peer victimization and school adjustment in a sample of 1,022 sixth-grade students. Measures used in this study include peer victimization, perceived peer non-support, school attachment, inattention problems, and academic achievement. Multivariate path analyses were conducted to test direct and mediation effects in the over-all model and to explore gender differences. The results provided support for the hypothesized model indicating that the relationship between peer victimization and school attachment is mediated by perceived peer non-support, and that school attachment is related to inattentive school behaviors and poor academic achievement. Paths indicated invariance across models for gender. Prevention and intervention implications of these findings are discussed.

    Injection drug users in Tirana, Albania and St. Petersburg, Russia were recruited into a study assessing HIV-related behaviors and HIV serostatus using Respondent Driven Sampling (RDS), a peer-driven recruitment sampling strategy that results in a probability sample. (Salganik M, Heckathorn DD. Sampling and estimation in hidden populations using respondent-driven sampling. Sociol Method. 2004;34:193–239). This paper presents a comparison of RDS implementation, findings on network and recruitment characteristics, and lessons learned. Initiated with 13 to 15 seeds, approximately 200 IDUs were recruited within 8 weeks. Information resulting from RDS indicates that social network patterns from the two studies differ greatly. Female IDUs in Tirana had smaller network sizes than male IDUs, unlike in St. Petersburg where female IDUs had larger network sizes than male IDUs. Recruitment patterns in each country also differed by demographic categories. Recruitment analyses indicate that IDUs form socially distinct groups by sex in Tirana, whereas there was a greater degree of gender mixing patterns in St. Petersburg. RDS proved to be an effective means of surveying these hard-to-reach populations. PMID:17075727

  8. Negotiated media effects. Peer feedback modifies effects of media's thin-body ideal on adolescent girls.

    PubMed

    Veldhuis, Jolanda; Konijn, Elly A; Seidell, Jacob C

    2014-02-01

    The present study introduces a theoretical framework on negotiated media effects. Specifically, we argue that feedback of peers on thin-body ideal media images and individual dispositions guide effects on adolescent girls' psychosocial responses to media exposure. Therefore, we examined the thin-body ideal as portrayed in media and peers' feedback on such thin-ideal images in their combined effects on adolescent girls' body dissatisfaction, objectified body consciousness, and social comparison with media models. Hence, media models and peer comments were systematically combined as incorporated entities in YouTube-formats. Hypotheses were tested in a 3 (media models: extremely thin vs. thin vs. normal weight)×3 (peer comments: 6kg-underweight vs. 3kg-underweight vs. normal-weight)×2 (appearance schematicity: lower vs. higher) between-subjects design (N=216). Results showed that peer comments indicating that a media model was 'only 3kg-underweight' exerted most negative responses, particularly in girls who strongly process appearance relevant information. Peer feedback interacts with media models in guiding perceptions of what is considered an 'ideal' body shape. Results highlight the important role of peers as well as individual predispositions in view of understanding how thin-ideal media images may impact adolescent girls' body image concerns.

    PubMed

    Mance, Jennifer; Edwards, Lindsey

    2012-05-01

    This study aimed to examine the relationship between psychological well-being and self-perception in adolescents with cochlear implants, in relation to their perceptions of hearing, deaf signing, and orally communicating deaf peers. Self-perceptions were examined in 22 cochlear implant users aged 12-18 years, using the repertory grid technique that allows the respondent to generate personally relevant 'identity' constructs. Psychological well-being was assessed using the Beck Youth Inventory, a series of five self-report questionnaires assessing anxiety, depression, disruptive behaviour, anger, and self-esteem. Correlational analyses indicated that perceiving oneself as close to any peer, irrespective of which peer, was associated with better psychological well-being. There was also a significant positive association between perceived degree of similarity specifically to hearing peers, and psychological well-being. The closer the implanted adolescents perceived themselves to be to their hearing peers, the better their overall psychological well-being. In contrast, perceiving oneself as more similar to deaf signing peers or deaf oral peers was not significantly associated with psychological well-being. The findings are discussed in the context of previous research on social comparison, Deaf identity, and the aims of cochlear implantation.

    2016-05-01

    Performing and teaching appropriate follow-up of outpatient laboratory results (LRs) is a challenge. The authors tested peer-review among residents as a potentially valuable intervention. Investigators assigned residents to perform self-review (n = 27), peer-review (n = 21), or self- + peer-review (n = 30) of outpatient charts. They also compared residence performance with that of historical controls (n = 20). In September 2012, residents examined 10 LRs from April 2012 onward. A second review in November 2012 ascertained whether performing chart review improved residents' practice behaviors. Initially, the least-square (LS) mean number of LRs without documentation of follow-up per resident in the self-, peer-, and self- + peer-review group was, respectively, 0.5 (SD 1.0), 1.0 (SD 1.7), and 0.9 (SD 1.3), and post intervention, this was 1.0 (SD 0.2), 0.3 (SD 0.2), and 0.6 (SD 0.2) (self- versus peer-review P = .03). Initially the LS mean follow-up time per resident in the self-, peer-, and self- + peer-review group was, respectively, 4.2 (SD 1.2), 6.9 (SD 1.4), and 5.9 (SD 1.2) days, and after the intervention, LS mean time was 5.0 (SD 0.5), 2.5 (SD 0.6), and 3.9 (SD 0.5) days (self- versus peer-review P < .01). Self-review was not associated with significant improvements in practice. In this comparison of self- and peer-review, only residents who performed peer-review demonstrated significant improvements in their documentation practices. These findings support the use of resident peer-review in improving LR follow-up, and potentially, in other, broader resident quality improvement initiatives.

    To compare European students' personal use and approval of illicit substance use with their perceptions of peer behaviours and attitudes, and investigate whether perceptions of peer norms are associated with personal use of illicit substances and attitudes. This study used baseline data from the Social Norms Intervention for the prevention of Polydrug usE (SNIPE) project involving 4482 students from seven European countries in 2012. Students completed an online survey which included questions on personal and perceived peer illicit substance use and personal and perceived peer attitude towards illicit substances. 8.3% of students reported having used illicit substances at least once in their life. 49.7% of students perceived that the majority of their peers have used illicit substances more frequently than themselves. The perception was significantly associated with higher odds for personal illicit substance use (OR: 1.97, 95% CI: 1.53-2.54). The perception that the majority of peers approve illicit substance use was significantly associated with higher odds for personal approval of illicit substance use (OR: 3.47, 95% CI: 2.73-4.41). Students commonly perceived that their peers used illicit subtances more often than themselves. We found an association between the perceived peer norms/attitudes and reported individual behaviour/attitudes. Copyright © 2014 Elsevier Inc. All rights reserved.

    2012-11-01

    Young adults are increasingly interacting with their peer groups online through social networking sites. These online interactions may reinforce or escalate alcohol and other drug (AOD) use as a result of more frequent and continuous exposure to AOD promotive norms; however, the influence of young adults' virtual networks on AOD use remains untested. The purpose of this study was to examine the association between the presence of AOD use content in online social networking, perceived norms (online norms regarding AOD use and anticipated regret with AOD use postings), and alcohol and marijuana use in a sample of 18- to 24-year-olds. Using an adapted web version of respondent-driven sampling (webRDS), we recruited a sample of 18- to 24-year-olds (N = 3,448) in the United States. Using multivariate regression, we explored the relationship between past-30-day alcohol and marijuana use, online norms regarding AOD use, peer substance use, and online and offline peer support. Alcohol use was associated with more alcohol content online. Anticipated regret and online peer support were associated with less alcohol use. Anticipated regret was negatively associated with marijuana use. Peer AOD use was positively associated with both alcohol and marijuana use. Peers play an important role in young adult alcohol and marijuana use, whether online or in person. Our findings highlight the importance of promoting online network-based AOD prevention programs for young adults in the United States.

  14. Peer effects on self-regulation in adolescence depend on the nature and quality of the peer interaction.

    2017-11-21

    Adolescence is a critical period for the development of self-regulation, and peer interactions are thought to strongly influence regulation ability. Simple exposure to peers has been found to alter decisions about risky behaviors and increase sensitivity to rewards. The link between peer exposure and self-regulation is likely to vary as a function of the type and quality of peer interaction (e.g., rejection or acceptance). Little is known about how the nature of interactions with peers influences different dimensions of self-regulation. We examined how randomization to acceptance or rejection by online "virtual" peers influenced multiple dimensions of self-regulation in a multisite community sample of 273 adolescents aged 16-17 years. Compared to a neutral condition, exposure to peers produced increases in cold cognitive control, but decreased hot cognitive control. Relative to peer acceptance, peer rejection reduced distress tolerance and increased sensitivity to losses. These findings suggest that different dimensions of adolescent self-regulation are influenced by the nature of the peer context: basic cognitive functions are altered by mere exposure to peers, whereas more complex decision making and emotion regulation processes are influenced primarily by the quality of that exposure.

    To identify prevalence and predictors of participation in the online drinking game 'neknomination' amongst university students. A convenience sample of 145 university students participated in a study about drinking behaviours, completing a questionnaire about their participation in neknomination, the Alcohol Use Disorders Identification Test, and the Resistance to Peer Influence Scale. Out of 145 students sampled, 54% took part in neknomination in the previous month. Mann-Whitney U tests revealed significantly higher scores on the Alcohol Use Disorders Identification Test, and significantly lower scores on the Resistance to Peer Influence Scale, for those who had participated in neknomination. A significant correlation was also shown between specific peer pressure to neknominate, and engagement in neknomination. A logistic regression analysis indicated that scores on the Alcohol Use Disorders Identification Test, but not the Resistance to Peer Influence Scale, predicted classification as an individual who participated in neknomination. We found that over half of respondents had participated in a neknomination game in the past month, with almost all male respondents having done so. Participation in neknomination was strongly associated with general hazardous drinking behaviour but not with resistance to peer influence. Further research is needed to understand the role of engagement with social media in drinking games and risky drinking.

    Fruit and vegetable (FV) attitudes and norms have been shown to influence intake in youth; yet research with low-income youth and studies supplementing self-report with objective measures of intake are lacking. Cross-sectional survey data on self-rated FV intake, FV attitudes, and FV norms were collected in a sample of 116 youth attending a residential summer camp serving low-income families. FV intake also was estimated by direct observation. Differences between self-rated and observed FV intake, perceived and observed peer intake, and perceived and peer-reported attitudes toward eating FVs were assessed with paired samples t tests. The role of FV attitudes, descriptive norms (perceived peer FV intake), injunctive norms (perceived peer attitudes toward eating FVs), and actual norms (observed peer FV intake and peer-reported FV attitudes) in predicting FV intake also was examined with multiple regression analysis. Youth misperceived their own and their peers' FV intake (i.e., overestimated intake of fruit and underestimated intake of vegetables) and believed that peers held less favorable attitudes toward eating FVs than was the case. The models predicting self-rated intake were significant, accounting for 34% of the variance in fruit intake and 28% of the variance in vegetable intake. Attitudes and descriptive norms were positively associated with FV intake, and observed peer fruit intake was negatively associated with fruit intake. Findings suggest that in low-income youth, FV attitudes, descriptive norms, and normative peer behavior predict perceived but not actual intake. Youth may benefit from intervention to promote favorable FV attitudes and norms. A focus on descriptive norms holds promise for improving self-rated intake in this population. © 2015 Society for Public Health Education.

    Maternal and paternal psychological control, peer attitudes, and the interaction of psychological control and peer attitudes at age 13 were examined as predictors of risky sexual behavior before age 16 in a community sample of 181 youth followed from age 13 to 16. Maternal psychological control moderated the link between peer attitudes and sexual behavior. Peer acceptance of early sex predicted greater risky sexual behaviors, but only for teens whose mothers engaged in high levels of psychological control. Paternal psychological control demonstrated the same moderating effect for girls; for boys, however, high levels of paternal control predicted risky sex regardless of peer attitudes. Results are consistent with the theory that peer influences do not replace parental influences with regard to adolescent sexual behavior; rather, parental practices continue to serve an important role either directly forecasting sexual behavior or moderating the link between peer attitudes and sexual behavior.

    The conjoint influence of child impulsiveness-inattention (I/I) and peer relationships on growth trajectories of conduct problems was assessed in a community sample of 267 boys and girls. I/I reliably predicted teacher- and parent-reported conduct problems at kindergarten entry and growth in those problems over the next 2 years for boys and girls. The relation of boys' I/I to conduct problems was mediated, in part, by peer rejection and involvement in coercive exchanges with peers. The relation of girls' I/I to conduct problems was less clearly mediated by peer processes, but peer difficulties had additive effects. The impact of peer relationships on trajectories of conduct problems was apparent to parents as well as to teachers. Although I/I increments risk for early and persisting conduct problems in concert with poor peer relationships, it does so in complex and gender-specific ways.

  13. PISA: Federated Search in P2P Networks with Uncooperative Peers

    NASA Astrophysics Data System (ADS)

    Ren, Zujie; Shou, Lidan; Chen, Gang; Chen, Chun; Bei, Yijun

    Recently, federated search in P2P networks has received much attention. Most of the previous work assumed a cooperative environment where each peer can actively participate in information publishing and distributed document indexing. However, little work has addressed the problem of incorporating uncooperative peers, which do not publish their own corpus statistics, into a network. This paper presents a P2P-based federated search framework called PISA which incorporates uncooperative peers as well as the normal ones. In order to address the indexing needs for uncooperative peers, we propose a novel heuristic query-based sampling approach which can obtain high-quality resource descriptions from uncooperative peers at relatively low communication cost. We also propose an effective method called RISE to merge the results returned by uncooperative peers. Our experimental results indicate that PISA can provide quality search results, while utilizing the uncooperative peers at a low cost.

  14. Genetic variation in GABRA2 moderates peer influence on externalizing behavior in adolescents.

    Genetic predisposition and environmental influences are both important factors in the development of problematic behavior leading to substance use in adolescence. Involvement with delinquent peers also strongly predicts adolescent externalizing behavior. Several lines of evidence support a role of GABRA2 on externalizing behavior related to disinhibition. However, whether this genetic association is influenced by the environment such as peer behavior remains unknown. We examined the moderating role of GABRA2 genetic variation on the socialization model of delinquent peer affiliation (at ages 12-14 years) on externalizing behavior (at ages 15-17 years) in the Michigan Longitudinal Study (MLS) adolescent sample. The sample consisted of 244 adolescents (75 females and 152 with at least one parent with a DSM-IV lifetime alcohol dependence/abuse diagnosis). Peer delinquent activity reported by the participant and teacher-reported adolescent externalizing behavior (Teacher Report Form (TRF) were assessed. No main effect of the GABRA2 SNP rs279826, which tags a large haplotype, on externalizing behavior was observed. However, there was a statistically reliable GABRA2 × peer delinquency interaction. The effect of peer delinquent involvement on externalizing scores and the rule breaking subscale is significantly stronger for those with the GG genotype compared to A-carriers, whereas there was no effect of genotype on externalizing in the absence of peer delinquent involvement. No interaction was observed for the aggression subscale. Our results suggest that the genetic effect of GABRA2 on externalizing behavior, more specifically on rule breaking is, at least in part, due to its effect on susceptibility to environmental exposure (i.e., peer delinquency).

    Peer crowds are macro-level subcultures that share similarities across geographic areas. Over the past decade, dozens of studies have explored the association between adolescent peer crowds and risk behaviors, and how they can inform public health efforts. However, despite the interest, researchers have not yet reported on crowd size and risk levels from a representative sample, making it difficult for practitioners to apply peer crowd science to interventions. The current study reports findings from the first statewide representative sample of adolescent peer crowd identification and health behaviors. Weighted data were analyzed from the 2015 Virginia Youth Survey of Health Behaviors ( n = 4,367). Peer crowds were measured via the I-Base Survey™, a photo-based peer crowd survey instrument. Frequencies and confidence intervals of select behaviors including tobacco use, substance use, nutrition, physical activity, and violence were examined to identify high- and low-risk crowds. Logistic regression was used to calculate adjusted odds ratios for each crowd and behavior. Risky behaviors clustered in two peer crowds. Hip Hop crowd identification was associated with substance use, violence, and some depression and suicidal behaviors. Alternative crowd identification was associated with increased risk for some substance use behaviors, depression and suicide, bullying, physical inactivity, and obesity. Mainstream and, to a lesser extent, Popular, identities were associated with decreased risk for most behaviors. Findings from the first representative study of peer crowds and adolescent behavior identify two high-risk groups, providing critical insights for practitioners seeking to maximize public health interventions by targeting high-risk crowds.

    Hydrostatic density determination for liquids is mainly performed by laboratories to provide means for calibrating liquid density measuring instruments such as oscillation-type density meters. From 2002 to 2005 the CIPM key comparison CCM.D-K2 'comparison of liquid density standards' was carried out piloted by the PTB. The aim was to compare the results of the density determination by the participating laboratories to support entries to the CMC tables in this sub-field. To provide further laboratories the possibility to support their entries to the CMC tables at the meeting of the EUROMET Working Group on Density in 2007 this comparison was agreed on. BEV (Austria) organized the comparison supported by the PTB (Germany). For the comparison samples of pentadecane, water, tetrachloroethylene and of an oil of high viscosity were measured in the temperature range from 5 °C to 60 °C at atmospheric pressure by hydrostatic weighing. The measurements were completed in 2008. The reference values of the first reports based on the draft of the CCM.D-K2. After the official publication of the CCM.D-K2 the reference values were recalculated and the report was finalised in 2015. Main text To reach the main text of this paper, click on Final Report.

    To examine the relative contribution of weapon carrying of peers, aggression, and victimization to weapon carrying of male and female adolescents over time. Data were derived from a population-based sample of male (N = 224) and female (N = 244) adolescents followed from grade 10 (M age = 15.5) to grade 11 (M age = 16.5). Peer networks were derived from best friend nominations. Self-reports were used to assess weapon carrying. Aggression and victimization were assessed using both self- and peer-reports. Use of dynamic social network modeling (SIENA) allowed prediction of weapon carrying in grade 11 as a function of weapon carrying of befriended peers, aggression, and victimization in grade 10, while selection processes and structural network effects (reciprocity and transitivity) were controlled for. Peer influence processes accounted for changes in weapon carrying over time. Self-reported victimization decreased weapon carrying 1 year later. Peer-reported victimization increased the likelihood of weapon carrying, particularly for highly aggressive adolescents. Boys were more likely to carry weapons than girls, but the processes associated with weapon carrying did not differ for boys and girls. These findings revealed that, in this population-based sample, weapon carrying of best friends, as well as aggression, contributed to the proliferation of weapons in friendship networks, suggesting processes of peer contagion as well as individual vulnerability to weapon carrying.

    The aim of this study was to examine the relationship between the perceived motivational climate, achievement goals, perfectionism and indices of peer relationships in a sample of young male and female Norwegian soccer players. The sample consisted of 1719 experienced soccer players (1231 males, 488 females) aged 12-19 years (mean = 14.9 years) participating in the Norway Cup international youth soccer competition. The players responded to a questionnaire measuring perceived peer acceptance and quality of friendship in soccer, perceived motivational climate, achievement goals and perfectionism in soccer. Canonical correlation analyses revealed that young female players who perceived the motivational climate as predominantly mastery oriented, and who were moderately task oriented and scored negatively on maladaptive perfectionism, reported better relations with their peers in soccer. Constructive peer relations were evident in that they scored positively on companionship with their best friend in soccer; they perceived this friend as being loyal and allowing of free discussion, and they reported being socially accepted by their peers in soccer. Mirroring these findings, young male players who perceived the motivational climate as predominantly performance oriented, who had a moderately negative score on task orientation but a quite strong positive score on maladaptive perfectionism, reported negative relationships with peers in terms of these aspects. They also reported being in conflict with their best soccer friend. The findings suggest that the qualities of motivation have a systematic relationship with peer acceptance and the quality of friendship in male and female youth soccer.

    Bullying victimization may be linked to psychosis but only self-report measures of victimization have been used so far. This study aimed (a) to investigate the differential associations of peer-nominated versus self-reported victim status with non-clinical psychotic experiences in a sample of young adolescents, and (b) to examine whether different types of self-reported victimization predict non-clinical psychotic experiences in these adolescents. Method A combination of standard self-report and peer nomination procedures was used to assess victimization. The sample (n = 724) was divided into four groups (exclusively self-reported victims, self- and peer-reported victims, exclusively peer-reported victims, and non-victims) to test for a group effect on non-clinical psychotic experiences. The relationship between types of victimization and non-clinical psychotic experiences was examined by a regression analysis. Self-reported victims, along with self- and peer-reported victims, scored higher than peer-reported victims and non-victims on non-clinical psychotic experiences. Self-reports of direct relational, indirect relational and physical victimization significantly improved the prediction of non-clinical psychotic experiences whereas verbal and possession-directed victimization had no significant predictive value. The relationship between victimization and non-clinical psychotic experiences is only present for self-reported victimization, possibly indicative of an interpretation bias. The observed discrepancy between self-report and peer-report highlights the importance of implementing a combination of both measures for future research.

    This study examined social functioning and facial expression recognition (FER) in children with neurofibromatosis type 1 (NF1) compared to typically developing peers. Specifically, the current research aimed to identify hypothesised relationships between neurocognitive ability, FER and social functioning. Children, ages 8 to 16, with NF1 (n = 23) and typically developing peers (n = 23) were recruited during regularly scheduled clinic visits and through advertisements on an institutional clinical trials website, respectively. Participants completed a measure of FER, an abbreviated intelligence test and questionnaires regarding their quality of life and behavioural functioning. Parents were also asked to complete questionnaires regarding the social-emotional and cognitive functioning of their child. As expected, there were significant differences between children with NF1 and typically developing peers across domains of social functioning and FER. Within the sample of children with NF1, there were no significant associations observed between cognitive measures, social functioning and facial recognition skills. Children with NF1 exhibited high rates of social impairment and weak FER skills compared to controls. The absence of associations between FER with cognitive and social variables, however, suggests something unique about this skill in children with NF1. Theoretical comparisons are made to children with autism spectrum disorders, as this condition may serve as a potentially useful model in better understanding FER in children with NF1. © 2016 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

    While maltreatment is known to impact social and emotional functioning, threat processing, and neural structure, the potentially dimorphic influence of sex on these outcomes remains relatively understudied. We investigated sex differences across these domains in a large community sample of children aged 10 to 14 years (n = 122) comprising 62 children with verified maltreatment experience and 60 well-matched nonmaltreated peers. The maltreated group relative to the nonmaltreated comparison group exhibited poorer social and emotional functioning (more peer problems and heightened emotional reactivity). Cognitively, they displayed a pattern of attentional avoidance of threat in a visual dot-probe task. Similar patterns were observed in males and females in these domains. Reduced gray matter volume was found to characterize the maltreated group in the medial orbitofrontal cortex, bilateral middle temporal lobes, and bilateral supramarginal gyrus; sex differences were observed only in the supramarginal gyrus. In addition, a disordinal interaction between maltreatment exposure and sex was found in the postcentral gyrus. Finally, attentional avoidance to threat mediated the relationship between maltreatment and emotional reactivity, and medial orbitofrontal cortex gray matter volume mediated the relationship between maltreatment and peer functioning. Similar mediation patterns were observed across sexes. This study highlights the utility of combining multiple levels of analysis when studying the "latent vulnerability" engendered by childhood maltreatment and yields tentative findings regarding a neural basis of sex differences in long-term outcomes for maltreated children.

  4. Reactive aggression and peer victimization from pre-kindergarten to first grade: accounting for hyperactivity and teacher-child conflict.

    PubMed

    Runions, Kevin C

    2014-12-01

    The role of reactive aggression in the development of peer victimization remains unclear due in part to a failure to account for confounding problems of behavioural undercontrol (e.g., hyperactivity). As well, the school social context has rarely been examined to see whether these risks are mediated by relationships with teachers. This study tests the prospective relations between reactive aggression, hyperactivity, victimization, and teacher-child (T-C) relationship, to determine whether conflict mediates the relationships between externalizing problems and victimization. A sample of 1,114 Australian students were followed from pre-kindergarten through first grade. Cross-lagged path analyses were conducted, with comparison of gender-moderating models and autocorrelation models. Full-information maximum likelihood was deployed to account for missingness. Best fitting models found that the relationship of early externalizing problems to later victimization was mediated by T-C conflict. No evidence of victimization increasing externalizing problems nor gender differences were observed. T-C conflict in kindergarten predicted subsequent increases in victimization, reactive aggression, and hyperactivity. Understanding the processes whereby externalizing problems confer risk of victimization involves understanding the whole social context of classrooms, including relationships with teachers. Finer-grained research is needed to better understand how peer dynamics may be influenced by observation of T-C relationships. Pre-service teacher education needs to ensure a focus on the potential social impact of teacher's relationships with students. © 2014 The British Psychological Society.

Using a peer nomination technique in a sample of incarcerated females (N = 86, age 15-24 years), our study is the first to examine the association between peer status and psychopathology in a correctional facility. Results indicated that a key indicator of likeability was prosocial behavior; popularity was related to leadership; and social impact was associated with aggression. Popularity might serve as a buffer against, and social impact as a risk factor for, psychosocial problems. Findings shed light on peer status as a mechanism underpinning female offenders’ problem behaviors and an entry point for targeted interventions. PMID:25598649

    Most studies tend to characterize peer influences as either positive or negative. In a sample of 1815 youth from 14 different schools in Caracas, Venezuela, we explored how two types of peer affiliations (i.e., deviant and drug-using peers) differentially mediated the paths from positive parenting to youth's externalizing behavior and licit and illicit drug use. We used Zero Inflated Poisson models to test the probability of use and the extent of use during the past 12 months. Results suggested that peer influences are domain specific among Venezuelan youth. That is, deviant peer affiliations mediated the path from positive parenting to youth externalizing behaviors, and peer drug-using affiliations mediated the paths to the drug use outcomes. Mediation effects were partial, suggesting that parenting explained unique variance in the outcomes after accounting for both peer variables, gender, and age. We discuss implications for the development of screening tools and for prevention interventions targeting adolescents from different cultures.

    Following a large, diverse sample of 4096 children in 27 schools, this study evaluated the impact of three aspects of peer relations, measured concurrently, on subsequent child aggressive-disruptive behavior during early elementary school – peer-dislike, reciprocated friends' aggressiveness, and classroom levels of aggressive-disruptive behavior. Teachers rated child aggressive-disruptive behavior in first and third grade, and peer relations were assessed during second grade. Results indicated that heightened classroom aggressive-disruptive behavior levels were related to proximal peer relations, including an increased likelihood of having aggressive friends and lower levels of peer-dislike of aggressive-disruptive children. Controlling for first grade aggressive-disruptive behavior, the three second grade peer experiences each made unique contributions to third grade child aggressive-disruptive behavior. These findings replicate and extend a growing body of research documenting the multifaceted nature of peer influence on aggressive-disruptive behavior in early elementary school. They highlight the importance of the classroom ecology and proximal peer relations in the socialization of aggressive-disruptive behavior. PMID:22545840

    Although research has examined the bivariate effects of teacher support, peer acceptance, and engagement, it remains unclear how these key classroom experiences evolve together, especially in late childhood. This study aims to provide a detailed picture of their transactional relations in late childhood. A sample of 586 children (M age  = 9.26 years, 47.1% boys) was followed from fourth to sixth grade. Teacher support and engagement were student-reported and peer acceptance was peer-reported. Autoregressive cross-lagged models revealed unique longitudinal effects of both peer acceptance and teacher support on engagement, and of peer acceptance on teacher support. No reverse effects of engagement on peer acceptance or teacher support were found. The study underscores the importance of examining the relative contribution of several social actors in the classroom. Regarding interventions, improving both peer acceptance and teacher support can increase children's engagement, and augmenting peer acceptance can help to increase teacher support.

    Research supports the efficacy of both cognitive dissonance (CD) and healthy weight (HW) eating disorders prevention, and indicates that CD can be delivered by peer-facilitators, which facilitates dissemination. This study investigated if peer-facilitators can deliver HW when it is modified for their use and extended follow-up of peer-facilitated CD as compared to previous trials. Based on pilot data, we modified HW (MHW) to facilitate peer delivery, elaborate benefits of the healthy-ideal, and place greater emphasis on consuming nutrient dense foods. Female sorority members (N=106) were randomized to either two 2-h sessions of CD or MHW. Participants completed assessment pre- and post-intervention, and at 8-week, 8-month, and 14-month follow-up. Consistent with hypotheses, CD decreased negative affect, thin-ideal internalization, and bulimic pathology to a greater degree post-intervention. Both CD and MHW reduced negative affect, internalization, body dissatisfaction, dietary restraint, and bulimic pathology at 14 months. Copyright © 2010 Elsevier Ltd. All rights reserved.

    To determine whether tutoring might be academically beneficial to the tutor, this study investigated the acquisition of spelling words by three elementary students in a peer tutoring program. The experimental design allowed a simultaneous comparison of each child's gain in performance on comparable word lists on which the child tutored another child, was tutored by another child, or neither gave nor received tutoring. The children's spelling improved nearly an equivalent amount on those words on which they tutored another child as on the words on which they were tutored; no such change was noted on the words on which they neither gave nor received tutoring. These findings, that peer tutoring is profitable for the tutor as well as the tutee, provide a basis for recommending peer tutoring as one method of individualizing education. PMID:16795552

  14. Moderators of peer contagion: a longitudinal examination of depression socialization between adolescents and their best friends.

    Prinstein, Mitchell J

    2007-01-01

    This longitudinal study examined peer contagion of depressive symptoms over an 18-month interval within a sample of 100 11th-grade adolescents. Three types of peer contagion moderators were examined, including characteristics of adolescents (social anxiety, global self-worth), friends (level of friends' peer-perceived popularity), and the relationship between them (friendship quality). Measures were collected using adolescents' and their friends' reports of depressive symptoms, adolescents' reports of social anxiety, global self-worth, friendship quality, and a sociometric assessment of peer-perceived popularity. Results indicated that among girls higher levels of social anxiety were associated with adolescents' greater susceptibility to peer contagion. Among boys, higher levels of friends' peer perceived popularity and lower levels of positive friendship quality each were associated with greater susceptibility to depressive symptom contagion.

    The aim of the present study was to investigate the relationship between child maltreatment and severe early adolescent peer-on-peer sexual aggression, using a multiple mediator model. The study comprised 330 male Grade 9 students with a mean age of 14.9 years (SD=0.5). Estimates from the mediation model indicated significant indirect effects of child physical abuse on sexual aggression via peer influence and insecure-hostile masculinity. No significant total effect of child sexual abuse and child neglect on sexual aggression was found. Findings of the present study identify risk factors that are potentially changeable and therefore of value in informing the design of prevention programs aiming at early adolescent peer-on-peer sexual aggression in at-risk youth.

    This study examined the influence of peers in meeting DSM-IV symptom criteria for an internalizing disorder in adolescents exposed to Hurricane Georges. Participants included a representative community sample of 905 youth (n = 476 boys) ages 11-17, residing in Puerto Rico. Data were gathered on hurricane exposure, symptoms of internalizing disorders, peer social support, peer violence, and peer substance use through in-person structured interviews with adolescents and caretakers from 1999 to 2000 in Puerto Rico, 12-27 months after Hurricane Georges. Hurricane exposure, peer violence, and peer substance use predicted whether adolescents met DSM-IV symptom criteria for a measured internalizing disorder. An interaction was found between hurricane exposure and peer violence, which indicated that hurricane exposure was significantly related to meeting DSM-IV symptom criteria for an internalizing disorder among adolescents who do not report associating with violent peers. However, for participants who reported high levels of peer violence, hurricane exposure did not convey additional risk for meeting DSM-IV symptom criteria for an internalizing disorder. With the increasing role peers play in adolescents' lives, understanding the influence of peers on the development of internalizing symptoms following hurricane exposure may assist in planning developmentally sensitive response plans.

    To examine the feasibility and potential benefits of early peer support to improve the health and quality of life of individuals with early inflammatory arthritis (EIA). Feasibility study using the 2008 Medical Research Council framework as a theoretical basis. A literature review, environmental scan, and interviews with patients, families and healthcare providers guided the development of peer mentor training sessions and a peer-to-peer mentoring programme. Peer mentors were trained and paired with a mentee to receive (face-to-face or telephone) support over 12 weeks. Two academic teaching hospitals in Toronto, Ontario, Canada. Nine pairs consisting of one peer mentor and one mentee were matched based on factors such as age and work status. Mentee outcomes of disease modifying antirheumatic drugs (DMARDs)/biological treatment use, self-efficacy, self-management, health-related quality of life, anxiety, coping efficacy, social support and disease activity were measured using validated tools. Descriptive statistics and effect sizes were calculated to determine clinically important (>0.3) changes. Peer mentor self-efficacy was assessed using a self-efficacy scale. Interviews conducted with participants examined acceptability and feasibility of procedures and outcome measures, as well as perspectives on the value of peer support for individuals with EIA. Themes were identified through constant comparison. Mentees experienced improvements in the overall arthritis impact on life, coping efficacy and social support (effect size >0.3). Mentees also perceived emotional, informational, appraisal and instrumental support. Mentors also reported benefits and learnt from mentees' fortitude and self-management skills. The training was well received by mentors. Their self-efficacy increased significantly after training completion. Participants' experience of peer support was informed by the unique relationship with their peer. All participants were unequivocal about the need for peer support for individuals with EIA. The intervention was well received. Training, peer support programme and outcome measures were demonstrated to be feasible with modifications. Early peer support may augment current rheumatological care. NCT01054963, NCT01054131.

  18. Caries and periodontal disease in Indigenous adults in Australia: a case of limited and non-contemporary data.

    2017-08-01

    Objective The aim of the present study was to identify all evidence about the prevalence and severity of clinically measured caries and periodontal disease in Indigenous adults in Australia published in peer-reviewed journals and to summarise trends over time. In addition, we examined whether the studies investigated associations between putative risk factors and levels of caries and periodontal disease. Methods PubMed was searched in September 2014, with no date limitations, for published peer-reviewed articles reporting the prevalence rates and/or severity of caries and periodontal disease in Indigenous adults living in Australia. Articles were excluded if measurement was not based on clinical assessment and if oral disease was reported only in a specific or targeted sample, and not the general population. Results The search identified 18 papers (reporting on 10 primary studies) that met the inclusion criteria. The studies published clinical data about dental caries and/or periodontal disease in Australian Indigenous adults. The studies reported on oral health for Indigenous adults living in rural (40%), urban (10%) and both urban and rural (50%) locations. Included studies showed that virtually all Indigenous adults living in rural locations had periodontal disease. The data also showed caries prevalence ranged from 46% to 93%. Although 10 studies were identified, the peer-reviewed literature was extremely limited and no published studies were identified that provided statistics for a significant proportion of Australia (Victoria, Tasmania, Queensland or the Australian Capital Territory). There were also inconsistencies in how the data were reported between studies, making comparisons difficult. Conclusions This review highlights a lack of robust and contemporary data to inform the development of policies and programs to address the disparities in oral health in Indigenous populations living in many parts of Australia. What is known about the topic? Many studies report that Indigenous people in Australia have poorer general health compared with non-Indigenous people. What does this paper add? This paper documents the available caries and periodontal disease prevalence and experience for Indigenous adults in Australia published in peer-reviewed journals. It demonstrates significant limitations in the data, including no data in several large Australian jurisdictions, inconsistency with reporting methods and most data available being for Indigenous adults living in rural locations. Therefore, the oral health data available in the peer-reviewed literature do not reflect the situation of all Indigenous people living in Australia. What are the implications for practitioners? It is important for oral health practitioners to have access to current and relevant statistics on the oral health of Indigenous Australians. However, we have highlighted significant evidence gaps for this population group within the peer-reviewed literature and identified the limitations of the available data upon which decisions are currently being made. This paper also identifies ways to capture and report oral health data in the future to enable more meaningful comparisons and relevance for use in policy development.

    2017-12-01

    This article aims to better understand the complex role of technology in peer victimization events with recent depressive symptomatology and suicide ideation (SI). Telephone interviews were conducted with a national sample of 791 youth in the United States, aged 10 to 20 years, collected from December 2013 to March 2014. Rates of any peer harassment victimization varied by past month depressive symptomatology and SI -28% of youth with no/low depressive symptomatology reported past year peer harassment as did 43% of youth with high depressive symptomatology without SI, and 66% of youth with SI. When examining the role of technology in peer harassment, youth experiencing any mixed harassment (i.e., those incidents that occurred both in-person and through technology) were almost 4 times more likely to report past month depressive symptoms without SI (RR adj = 3.9, 95% confidence interval [CI] = [1.5, 10.0], p ≤ .01) and 7.5 times (95% CI = [1.9, 28.9], p ≤ .01) more likely to report past month SI compared with youth who had no past year peer harassment. Given the multilayered relationships among these variables, schools, medical, and mental health professionals might screen youth who are involved in higher risk peer victimization situations, for depressive symptoms and SI to improve their access to appropriate mental health services.

    Early smoking is considered an indicator for risky behaviour in adolescents. Although social indicators predicting adolescent smoking are known, biological indicators have not been defined. This study aimed to establish whether salivary testosterone could be used as a "predictive biomarker" for smoking-associated peer pressure. Saliva samples were collected from Bruneian adolescents (aged 13-17 years) by the passive drool method. Salivary testosterone concentration was determined by enzyme-linked immunosorbent assay. Salivary testosterone concentration and smoking-associated peer pressure indicators were compared between adolescent males and females and statistical significance was determined by an independent samples t-test. A significant positive relationship between smoking-associated peer pressure and salivary testosterone levels in adolescents was found. However, this relationship was not significant when males and females were considered separately. Our data suggest that students who have tried cigarette smoking and have friends who are cigarette smokers have higher salivary testosterone levels.

    This study examines variability in patterns of peer group antipathy. Same-grade adolescent peer groups were identified from sociometric nominations of preferred affiliates in a community sample of 600 Finnish 9th grade middle school students (M = 15.0 years-old). Hierarchical linear modeling determined characteristics of youth in actor groups (nominators) that predicted antipathy for youth in target groups (nominatees) on the basis of target group characteristics. Most antipathies were based on dissimilarity between groups representing the mainstream culture and groups opposed to it. The higher a peer group's school burnout, the more its members disliked students in peer groups with higher school grades and students in peer groups with higher sports participation. Conversely, the higher a peer group's school grades, the more its members disliked students in peer groups with higher school burnout. Students in peer groups with less problem behavior disliked students in peer groups with more problem behavior. There was some evidence of rivalry within the mainstream culture: The higher a group's school grades, the more its members disliked those in groups whose members participated in sports.

    Peer victimization is a common stressor experienced by children. Although peer victimization has been studied extensively, few studies have examined the potential link between peer victimization and posttraumatic stress disorder (PTSD), and no studies of which we are aware have examined this link among children in primary school. The paucity of studies examining the link between PTSD and peer victimization in primary school is surprising because peer victimization occurs more frequently and is more likely to be physical among 7- and 8-year-old children. This study assessed the relationship between peer victimization and PTSD in a sample of 358 elementary school children (ages 6-11 years). Results indicated that peer victimization accounted for 14.1% of PTSD symptom severity among boys and 10.1% among girls. Additionally, we found gender differences in the types of peer victimization that were most associated with PTSD symptom severity (d = 0.38). The long-term developmental consequences that may be associated with peer victimization-linked PTSD symptomatology are discussed. Copyright © 2015 International Society for Traumatic Stress Studies.

    Appearance-related attention biases are thought to contribute to body image disturbances. We investigated how preoccupation with body image is associated with attention biases to body size, focusing on the role of social comparison processes and automaticity. Thirty-six women varying on self-reported preoccupation compared their actual body size to size-modified images of either themselves or a figure-matched peer. Amplification of earlier (N170, P2) and later (P3, LPP) ERP components recorded under low vs. high concurrent working memory load were analyzed. Women with high preoccupation exhibited an earlier bias to larger bodies of both self and peer. During later processing stages, they exhibited a stronger bias to enlarged as well as reduced self-images and a lack of sensitivity to size-modifications of the peer-image. Working memory load did not affect these biases systematically. Current findings suggest that preoccupation with body image involves an earlier attention bias to weight increase cues and later over-engagement with own figure. Copyright © 2018 Elsevier B.V.

    Accuracy in the reporting of studies in conference abstracts is important because the majority of studies in such abstracts are never further detailed in peer-reviewed publications, and data from such abstracts may be used in systematic reviews. Previous research on interventional studies in human biomedicine indicates that there is no guarantee of consistency between a conference abstract and paper in the reporting of results and other key variables. However, no research has been done to determine if this lack of reporting consistency in abstracts and papers extends to interventional studies in pre-harvest/harvest-level food safety. The goal of this study was to compare outcome results and other key variables between conference abstracts and subsequent peer-reviewed publications describing studies of pre-harvest and abattoir-level interventions against foodborne pathogens, and to determine whether the agreement in the results or key variables was associated with the time to full publication. A systematic search identified 59 conference abstracts with matching peer-reviewed papers (matches), and data on variables including outcome measures and results, pathogens, species, interventions, overall efficacy of intervention, sample size and housing were extracted from both the conference abstracts and the papers. The matching of variables between abstracts and papers was described, and logistic regression used to test for associations between variable matching and time to publication. Sample size was only provided for both abstract and paper in 24 matches; the same sample size was reported in 20 of these matches. Most other variables were reported in the majority of abstracts/papers, and with the exception of outcomes and intervention effect, the reporting of variables was relatively consistent. There was no significant difference in the numbers of authors, with the first author the same in 78.3% of matches. Of 231 outcome measures reported in both abstracts and papers, nearly one third (77% or 32.2%) had different results, with 32 changing direction of effect. More than a quarter of matches involved at least one significant change in outcome result. The overall conclusion on the efficacy of the intervention changed in 10.7% of matches. There was a significant association between increased time to publication and differences in the number of authors, and having fewer outcome measures in the abstract reported in the paper. These results suggest that data from conference abstracts should be considered with caution. Copyright © 2010 Elsevier B.V. All rights reserved.

    Children with attention-deficit/hyperactivity disorder (ADHD) are at increased risk for the development of depression, with evidence that peer and academic difficulties mediate predictions of later depression from ADHD. The present study hypothesized that parent-child relationship difficulties may be an additional potential mediator of this association. Academic, peer, and parent-child functioning were tested as mediators of the association of attention problems and depression in two distinctly different, yet complementary samples. Study 1 was a cross-sectional sample of 230 5–10 year-old children with and without ADHD. Study 2 was a prospective longitudinal sample of 472 youth followed prospectively from birth to age 20 at risk for depression. Despite differences in age, measures, and designs, both studies implicated peer and parent-child problems as unique mediators of depressive symptoms, although academic difficulties did not uniquely mediate the ADHD-depression association. Further, inattention symptoms, but not hyperactivity, predicted depressive symptoms via the disruption of interpersonal functioning. The inclusion of oppositional defiant disorder into models impacted results, and supported its independent role in parent-child problems. Implications include support for interventions that target interpersonal competence, which may effectively reduce the risk of depression among children with ADHD. PMID:24016021

    Using data from the National Longitudinal Survey of Adolescent to Adult Health, we estimate the effect of peers' alcohol consumption and alcohol prices on the drinking habits of high-school-age youth. We use the two-stage residual inclusion method to account for the endogeneity of peer drinking in nonlinear models. For our sample of high school students, we find that peer effects are statistically and economically significant regarding the choice to participate in drinking but are not significant for the frequency of drinking, including binge drinking. Regarding alcohol prices, even though we have good price variation in our sample, alcohol prices are not found to be significant. The results are important for policymakers who are considering policies to reduce underage drinking, as we conclude that no significant impact on underage drinking will result from low-tax states' increasing excise taxes on alcohol so they are similar to those of high-tax states. Policymakers may choose to focus instead on the influence of peers and changing the social norm behavior. Copyright © 2016 Elsevier B.V. All rights reserved.

    Past research has shown that locus of control plays an important role in a wide range of behaviors, such as academic achievement and positive social behaviors. However, little is known about whether locus of control plays the same role in minority adolescents' peer relationships. The current study examined ethnic differences in the associations between locus of control and peer relationships in early adolescence using samples from the Early Childhood Longitudinal Study (ECLS-K: 5,612 Caucasian, 1,562 Hispanic, 507 Asian, and 908 African-American adolescents) and the National Education Longitudinal Study (NELS: 8,484 Caucasian, 1,604 Hispanic, and 860 Asian, and 1,228 African American adolescents). Gender was approximately evenly split in both samples. The results from the two datasets were highly consistent. Significant interactions between ethnicity and locus of control indicated that having a more internal locus of control was particularly important for Caucasian students' peer relationships (ECLS-K) and social status (NELS), but less so for Asian, Hispanic, and African American students. Our findings suggest that the role of locus of control in peer relationship is contingent upon culture.

    Peer influence processes have been documented extensively for a wide range of maladaptive adolescent behaviors. However, peer socialization is not inherently deleterious, and little is known about whether adolescents influence each other's prosocial behaviors, or whether some peers are more influential than others towards positive youth outcomes. This study addressed these questions using an experimental "chat room" paradigm to examine in vivo peer influence of prosocial behavior endorsement. A school-based sample of 304 early adolescents (55% female, 45% male; M(age) = 12.68) believed they were interacting electronically with same-gender grademates (i.e., "e-confederates"), whose peer status was experimentally manipulated. The participants' intent to engage in prosocial behaviors was measured pre-experiment and in subsequent "public" and "private" experimental sessions. Overall, the adolescents conformed to the e-confederates' prosocial responses in public; yet, these peer influence effects were moderated by the peer status of the e-confederates, such that youth more strongly conformed to the high-status e-confederates than to the low-status ones. There also was some evidence that these peer influence effects were maintained in the private session, indicating potential internalization of prosocial peer norms. These findings help bridge the positive youth development and peer influence literatures, with potential implications for campaigns to increase prosocial behaviors.

    Teachers' legitimacy is central to school functioning. Teachers' justice, whether distributive or procedural, predicts teachers' legitimacy. What is still do be found, and constitutes the goal of this paper, is whether unjust treatment by a teacher affects the legitimacy of the teacher differently when the student knows that the teacher was fair to a peer (comparative judgement) or when the student does not have that information (autonomous judgement). A total of 79 high school students participated in Study 1; 75 high school students participated in Study 2. Two experimental studies with a 2 justice valence (just, unjust) × 2 social comparison processes (autonomous judgements, comparative judgements) between-participants design were conducted. Study 1 addressed distributive justice and Study 2 addressed procedural justice. The dependent variable was teachers' legitimacy. In both studies, situations perceived as just led to higher teachers' legitimacy than situations perceived as unjust. For the distributive injustice conditions, teachers' legitimacy was equally lower for autonomous judgement and comparative judgement conditions. For procedural injustice, teachers' legitimacy was lower when the peer was treated justly and the participant was treated unfairly, compared with the condition when the participants did not know how the teacher treated the peer. We conclude that teachers' injustice affects teachers' legitimacy, but it does it differently according to the social comparisons involved and the type of justice involved. Moreover, these results highlight that social comparisons are an important psychological process and, therefore, they should be taken into account in models of justice. © 2016 The British Psychological Society.

    In 2007 and 2008 respectively, the Laboratoire national de métrologie et d'essais-Laboratoire national Henri Becquerel (LNE-LNHB), France and the National Physical Laboratory (NPL), UK, submitted ampoules with between 10 MBq and 130 MBq activity of 99mTc to the International Reference System (SIR), to update their results in the BIPM.RI(II)-K1.Tc-99m comparison. Together with the four other national metrology institutes (NMI) that are participants, thirteen samples have been submitted since 1983. The key comparison reference value (KCRV) has been recalculated to include the latest primary results of the PTB and the LNE-LNHB as this makes the evaluation more robust. The degrees of equivalence between each equivalent activity measured in the SIR are given in the form of a matrix for all six NMIs. A graphical presentation is also given. Main text.

    The growing awareness of climate change/global warming and continuing concerns regarding stratospheric ozone depletion will require future measurements and standards for many compounds, in particular halocarbons that are linked to these issues. In order to track and control the emissions of these species globally in the atmosphere, it is necessary to demonstrate measurement equivalence at the highest levels of accuracy for assigned values of standards. This report describes the results of a key comparison for several of the more important halocarbons at atmospheric concentration levels. The comparison includes the chlorofluorocarbons (CFCs) dichlorodifluoromethane (CFC 12), trichlorofluoromethane (CFC 11), and 1,1,2 trichlorotrifluoroethane (CFC 113); the hydrochlorofluorocarbons (HCFCs) chlorodifluoromethane (HCFC 22) and 1-chloro-1,1-difluoroethane (HCFC 142b); and the hydrofluorocarbon (HFC) 1,1,1,2 tetrafluoroethane (HFC 134a), all in a dried whole air sample. The objective of this key comparison is to compare the measurement capabilities of the participants for these halocarbons at trace atmospheric levels. Main text.

    Background Genetic predisposition and environmental influences are both important factors in the development of problematic behavior leading to substance use in adolescence. Involvement with delinquent peers also strongly predicts adolescent externalizing behavior. Several lines of evidence support a role of GABRA2 on externalizing behavior related to disinhibition. However, whether this genetic association is influenced by the environment such as peer behavior remains unknown. Methods We examined the moderating role of GABRA2 genetic variation on the socialization model of delinquent peer affiliation (at ages 12–14 years) on externalizing behavior (at ages 15–17 years) in the Michigan Longitudinal Study (MLS) adolescent sample. The sample consisted of 244 adolescents (75 females and 152 with at least one parent with a DSM-IV lifetime alcohol dependence/abuse diagnosis). Peer delinquent activity reported by the participant and teacher-reported adolescent externalizing behavior (Teacher Report Form (TRF) were assessed. Results No main effect of the GABRA2 SNP rs279826, which tags a large haplotype, on externalizing behavior was observed. However, there was a statistically reliable GABRA2 × peer delinquency interaction. The effect of peer delinquent involvement on externalizing scores and the rule breaking subscale is significantly stronger for those with the GG genotype compared to A-carriers, whereas there was no effect of genotype on externalizing in the absence of peer delinquent involvement. No interaction was observed for the aggression subscale. Conclusion Our results suggest that the genetic effect of GABRA2 on externalizing behavior, more specifically on rule breaking is, at least in part, due to its effect on susceptibility to environmental exposure (i.e., peer delinquency).

    Objective Online health communities offer a diverse peer support base, yet users can struggle to identify suitable peer mentors as these communities grow. To facilitate mentoring connections, we designed a peer-matching system that automatically profiles and recommends peer mentors to mentees based on person-generated health data (PGHD). This study examined the profile characteristics that mentees value when choosing a peer mentor. Materials and Methods Through a mixed-methods user study, in which cancer patients and caregivers evaluated peer mentor recommendations, we examined the relative importance of four possible profile elements: health interests, language style, demographics, and sample posts. Playing the role of mentees, the study participants ranked mentors, then rated both the likelihood that they would hypothetically contact each mentor and the helpfulness of each profile element in helping the make that decision. We analyzed the participants’ ratings with linear regression and qualitatively analyzed participants’ feedback for emerging themes about choosing mentors and improving profile design. Results Of the four profile elements, only sample posts were a significant predictor for the likelihood of a mentee contacting a mentor. Communication cues embedded in posts were critical for helping the participants choose a compatible mentor. Qualitative themes offer insight into the interpersonal characteristics that mentees sought in peer mentors, including being knowledgeable, sociable, and articulate. Additionally, the participants emphasized the need for streamlined profiles that minimize the time required to choose a mentor. Conclusion Peer-matching systems in online health communities offer a promising approach for leveraging PGHD to connect patients. Our findings point to interpersonal communication cues embedded in PGHD that could prove critical for building mentoring relationships among the growing membership of online health communities.

    Adults with intellectual disability have poorer health than their non-disabled peers. However, little is known about the health of the 'hidden majority' of adults with primarily mild intellectual disability who do not use intellectual disability services. The aims of the present study were: to estimate the physical health status of a population-based sample of British adults with and without mild intellectual disability while controlling for any potentially confounding effects resulting from between-group differences in gender, age, socio-economic disadvantage and neighborhood social capital. Secondary analysis of data from Understanding Society, a new longitudinal study focusing on the life experiences of UK citizens. We identified 299 participants aged 16-49 (1.2 % of the unweighted age-restricted sample) as having intellectual disability, and 22,927 as not having intellectual disability. Multivariate logistic regression was used to investigate between group differences adjusting for potential confounding personal characteristics (e.g., gender). Unadjusted comparisons indicated that British adults with intellectual disability have markedly poorer health than their non-disabled peers on the majority of indicators investigated including self-rated health, multiple morbidity, arthritis, cancer, diabetes, obesity, measured grip strength, measured lung function and polypharmacy. Adjusting for between-group differences in age and gender had a marginal impact on these estimates. Further adjusting for between-group differences in socio-economic disadvantage and neighborhood quality had a more marked impact on estimates with the number of statistically significant differences reducing from 13 to 8 and statistically significant attenuation of odds on three indicators (self-rated health, SF-12 physical component and multiple morbidity). The 'hidden majority' of adults with primarily mild intellectual disability who do not use intellectual disability services have significantly poorer health than their non-disabled peers. This may, in part, reflect their increased risk of exposure to well established 'social determinants' of poorer health.

    A variety of peer support schemes are now widely used in schools, notably to reduce bullying. However, there has been little systematic investigation of the impact and effectiveness of these approaches. To assess the impact of a peer counselling scheme on peer counsellors and the school community. The research was conducted in a North London all-girls state secondary school. Data were collected from all lower school classes (years 7, 8, and 9) and some staff members, in addition to year 10 peer counsellors and an age equivalent comparison group. A detailed 1-year longitudinal study combined qualitative and quantitative methods of assessment. Peer counsellors benefited from their involvement through an acquisition of transferable communication and interpersonal skills, and, compared to age-matched control pupils, had increased social self-esteem. There were no reductions in self-reported bullying and victimization, but in general pupils believed that there was less bullying in school and that the school was doing more about bullying, with year 7 students showing the most positive changes. Peer-counselling schemes can improve self-esteem of peer supporters, and also impact positively on perceptions of bullying in the school; but impact on actual experiences of bullying is less clear, and there may be problems with the acceptance and use of such programmes by older students.

    This study examines peer resistance skills following a 21-lesson classroom-based intervention to build healthy relationships and decrease abusive and health-risk behaviors among adolescents. The Fourth R instructs students in positive relationship skills, such as negotiation and delay, for navigating challenging peer and dating scenarios. Observational data from 196 grade 9 students participating in a larger cluster randomized controlled trial were used to evaluate post-intervention acquisition of peer resistance skills. Pairs of students engaged in a role play paradigm with older student actors, where they were subjected to increasing pressure to comply with peer requests related to drugs and alcohol, bullying, and sexual behavior. Specific and global measures of change in peer resistance responses were obtained from two independent sets of observers, blinded to condition. Specific peer resistance responses (negotiation, delay, yielding to pressure, refusal, and compliance) were coded by research assistants; global peer resistance responses were rated by teachers from other schools (thinking / inquiry, application, communication, and perceived efficacy). Students who received the intervention were more likely to demonstrate negotiation skills and less likely to yield to negative pressure relative to controls. Intervention students were also more likely to use delay than controls; control girls were more likely to use refusal responses; the number of times students complied with peer requests did not differ. Teacher ratings demonstrated significant main effects favoring intervention youth on all measures. Program and research implications are highlighted.

    Peer support from community health workers, promotores de salud, and others through community and health care organizations can provide social support and other assistance that enhances health. There is substantial evidence for both the effectiveness and the cost-effectiveness of peer support, as well as for its feasibility, reach, and sustainability. We discuss findings from Peers for Progress, a program of the American Academy of Family Physicians Foundation, to examine when peer support does not work, guide dissemination of peer support programs, and help integrate approaches such as e-health into peer support. Success factors for peer support programs include proactive implementation, attention to participants' emotions, and ongoing supervision. Reaching those whom conventional clinical and preventive services too often fail to reach; reaching whole populations, such as people with diabetes, rather than selected samples; and addressing behavioral health are strengths of peer support that can help achieve health care that is efficient and of high quality. Challenges for policy makers going forward include encouraging workforce development, balancing quality control with maintaining key features of peer support, and ensuring that underresourced organizations can develop and manage peer support programs.

    Peer video modeling was compared to self video modeling to teach 3 children with autism to respond appropriately to (i.e., identify or label) novel letters. A combination multiple baseline and multielement design was used to compare the two procedures. Results showed that all 3 participants met the mastery criterion in the self-modeling condition, whereas only 1 of the participants met the mastery criterion in the peer-modeling condition. In addition, the participant who met the mastery criterion in both conditions reached the criterion more quickly in the self-modeling condition. Results are discussed in terms of their implications for teaching new skills to children with autism.

    Appearance comparison has consistently been shown to engender body image dissatisfaction. To date, most studies have demonstrated this relationship between appearance comparison and body image dissatisfaction in the context of conventional media images depicting the thin-ideal. Social comparison theory posits that people are more likely to compare themselves to similar others. Since social media forums such as Facebook involve one's peers, the current study aimed to determine whether the relationship between appearance comparison and body image dissatisfaction would be stronger for those exposed to social media images, compared to conventional media images. A sample of 193 female first year university students were randomly allocated to view a series of either Facebook or conventional media thin-ideal images. Participants completed questionnaires assessing pre- and post- image exposure measures of thin-ideal internalisation, appearance comparison, self-esteem, Facebook use and eating disorder risk. Type of exposure was not found to moderate the relationship between appearance comparison and changes in body image dissatisfaction. When analysed according to exposure type, appearance comparison only significantly predicted body image dissatisfaction change for those exposed to Facebook, but not conventional media. Facebook use was found to predict higher baseline body image dissatisfaction and was associated with higher eating disorder risk. The findings suggest the importance of extending the body image dissatisfaction literature by taking into account emerging social media formats. It is recommended that interventions for body image dissatisfaction and eating disorders consider appearance comparison processes elicited by thin-ideal content on social media forums, such as Facebook, in addition to conventional media.

  19. Improving outcomes using German Inpatient Quality Indicators in conjunction with peer review procedures.

    PubMed

    Mansky, Thomas; Völzke, Tatjana; Nimptsch, Ulrike

    2015-01-01

    Some hospital comparisons seem to generate confusion because different methods of outcome comparisons lead to different results in hospital rankings. This article questions the concept of overall comparisons of hospitals, which are multiproduct enterprises and may have specialties that provide good results in some areas despite having worse outcomes in others. Therefore, the authors argue for a disease specific view of outcome measurement. The concept of the German Inpatient Quality Indicators is explained. These indicators cover volume, mortality, and other information by a disease specific approach, which includes information for potential patients as well as specific feedback to the physicians responsible for the respective specialty. This article focuses on the feedback to the hospitals and explains how these indicators can be used for improvement in conjunction with a peer review process. The indicators provide information to the hospitals regarding their relative position because German reference values are available for all indicators. Thus, the indicators can serve as a trigger instrument for identifying possible quality problems. Based on these indications, peer review can be used to analyze the treatment processes and to eventually verify weaknesses and define actions for improvement. The first studies indicate that the use of this approach within hospital quality management can largely improve hospital outcomes in hospitals with subpar results compared to the German average.

    The aim of this study was to determine the validity of peer evaluation for team-based learning (TBL) classes in dental education in comparison with the term-end examination records and TBL class scores. Examination and TBL class records of 256 third- and fourth-year dental students in six fixed prosthodontics courses from 2013 to 2015 in one dental school in Japan were investigated. Results of the term-end examination during those courses, individual readiness assurance test (IRAT), group readiness assurance test (GRAT), group assignment projects (GAP), and peer evaluation of group members in TBL classes were collected. Significant positive correlations were found between all combinations of peer evaluation, IRAT, and term-end examination. Individual scores also showed a positive correlation with group score (total of GRAT and GAP). From the investigation of the correlations in the six courses, significant positive correlations between peer evaluation and individual score were found in four of the six courses. In this study, peer evaluation seemed to be a valid index for learning performance in TBL classes. To verify the effectiveness of peer evaluation, all students have to realize the significance of scoring the team member's performance. Clear criteria and detailed instruction for appropriate evaluation are also required.

    2017-01-01

    Using a qualitative monozygotic (MZ) twin differences design we explored whether adolescent MZ twins report discordant peer relationships and, if so, whether they perceive them as causes, consequences or correlates of discordant behaviour. We gathered free-response questionnaire data from 497 families and conducted in-depth telephone interviews with 97 of them. Within this dataset n = 112 families (23% of the sample) described discordant peer relationships. Six categories of discordance were identified (peer victimisation, peer rejection, fewer friends, different friends, different attitudes to friendship and dependence on co-twin). Participants described peer relationship discordance arising as a result of chance occurrences, enhanced vulnerability in one twin or discordant behaviour. Consequences of discordant peer relationships were seen as discordance in self-confidence, future plans, social isolation, mental health and interests. In all cases the twin with worse peer experiences was seen as having a worse outcome. Specific hypotheses are presented. PMID:28727730

    This meta-analytic review examines the association between attachment during the early life course and social competence with peers during childhood, and compares the strength of this association with those for externalizing and internalizing symptomatology. Based on eighty independent samples (N = 4,441), the association between security and peer competence was significant (d = 0.39, CI 0.32; 0.47) and not moderated by the age at which peer competence was assessed. Avoidance (d = 0.17, CI 0.05; 0.30), resistance (d = 0.29, CI 0.09; 0.48), and disorganization (d = 0.25, CI 0.10; 0.40) were significantly associated with lower peer competence. Attachment security was significantly more strongly associated with peer competence than internalizing (but not externalizing) symptomatology. Discussion focuses on the significance of early attachment for the development of peer competence versus externalizing and internalizing psychopathology. PMID:24547936

    Time-sampled observations of Head Start preschoolers' (N = 264; 51.5% boys; 76% Mexican American; M = 53.11 and SD = 6.15 months of age) peer play in the classroom were gathered during fall and spring semesters. One year later, kindergarten teachers rated these children's school competence. Latent growth models indicated that, on average, children's peer play was moderately frequent and increased over time during preschool. Children with higher initial levels or with higher slopes of peer play in Head Start had higher levels of kindergarten school competence. Results suggest that Head Start children's engagement with peers may foster development of skills that help their transition into formal schooling. These findings highlight the importance of peer play, and suggest that peer play in Head Start classrooms contributes to children's adaptation to the demands of formal schooling. PMID:24882941

    Recent research highlights the role of peer victimization in students’ adjustment across a variety of domains (e.g., academic, social), but less often identifies potential mediating variables. In the current study, we tested for direct effects from peer victimization to adolescents’ academic behavior and alcohol use, as well as indirect effects through school belonging. Adolescents from two large samples (middle school: N = 2,808; high school: N = 6,821) self-reported on peer victimization, school belonging, academic outcomes (GPA, school truancy), and alcohol use (lifetime, past 30 days). Two-group structural equation models revealed (a) direct and indirect paths from peer victimization to academic functioning; (b) indirect, but not direct, effects through school belonging for lifetime drinking; and (c) direct and indirect effects from peer victimization to current drinking. Findings implicate school belonging as a mediator between peer victimization and important outcomes in adolescence. PMID:27087793

    Effective instructional planning and intervening rely heavily on accurate understanding of students' growth, but relatively few researchers have examined mathematics achievement trajectories, particularly for students with special needs. We applied linear, quadratic, and piecewise linear mixed-effects models to identify the best-fitting model for mathematics development over elementary and middle school and to ascertain differences in growth trajectories of children with learning disabilities relative to their typically developing peers. The analytic sample of 2150 students was drawn from the Early Childhood Longitudinal Study - Kindergarten Cohort, a nationally representative sample of United States children who entered kindergarten in 1998. We first modeled students' mathematics growth via multiple mixed-effects models to determine the best fitting model of 9-year growth and then compared the trajectories of students with and without learning disabilities. Results indicate that the piecewise linear mixed-effects model captured best the functional form of students' mathematics trajectories. In addition, there were substantial achievement gaps between students with learning disabilities and students with no disabilities, and their trajectories differed such that students without disabilities progressed at a higher rate than their peers who had learning disabilities. The results underscore the need for further research to understand how to appropriately model students' mathematics trajectories and the need for attention to mathematics achievement gaps in policy.

    Despite a growing body of research on parental management of peer relationships, little is known about the relationship between parental management of peers and early adolescents' social skills or the precursors to parental management of peer relationships. The goals of this short-term longitudinal investigation were to examine the relationship between parental management of peers (consulting and guiding), conflict about peers, and adolescents' social skills (cooperation, assertion, responsibility, empathy, and self-control) and to examine potential precursors (goals of improving peer relationships and beliefs about authority over peer relationships) to parental management of peer relationships. A predominantly White sample (71%) of 75 seventh-graders (57% female) and their primary caregivers participated in the 9-month investigation. Caregivers completed questionnaires regarding goals of improving their adolescents' peer relationships, beliefs about parental authority over peer relationships, parental management of peers, and adolescents' social skills. Adolescents completed questionnaires regarding their social skills. Path analyses suggest that a greater number of caregivers' goals of improving peer relationships and higher beliefs about parental authority over peers were related to higher levels of consulting, guiding, and conflict about peers. Higher levels of conflict about peers in conjunction with higher levels of consulting were related to lower levels of assertion and responsibility in peer relationships over time. When parents reported having a greater number of goals of improving peer relationships, adolescents reported higher levels of cooperation, assertion, empathy, and self control over time. Findings suggest that caregivers' goals and beliefs are important in predicting parental management of peer relationships and adolescents' social skills over time, and that conflict about peers undermines caregivers' efforts to be positively involved in adolescents' peer relationships.

    In view of the developmental approach to sexual behavior, this article presents the stages of sexual behavior leading to coitus in four grades of high school students in Israel and the sociodemographic factors associated with initiating coitus. Analyses were based on data from the first national study dealing comprehensively with sexuality in 30 years. A self-administered questionnaire was completed by a random sample of 4,609 students of the General Educational (secular) system that included 68% of the Hebrew-speaking sector or 55% of all students in Israel. Our findings indicated a progressive set of stages of sexual behavior forming a Guttman scale, from kissing and petting over the clothes though petting under the clothes and genital touching to coitus. In comparison to results of a 1970 Israeli survey, we found an increase in practice in all Guttman scale stages of sexual behavior, as well as a diminished gap between genders. The gap fully disappeared in the three lower stages. Predictive variables of coitus initiation included gender, religiosity, immigration status, family structure, perceptions of academic achievements, and the proportion of peers practicing coitus. In addition to gender, perception of the proportion of peers that already practiced intercourse was the best predictor followed by grade, perception of academic achievement, and family structure. Marked differences were noticed between genders regarding associations with religiosity and immigration status. The discussion focused on comparisons to findings in other countries, the contribution of the findings to the understanding of Israeli adolescents' sexual behavior, and practical educational implications.

    2015-07-01

    Nearly all aspects of human development are influenced by genetic and environmental factors, which conjointly shape development through several gene-environment interplay mechanisms. More recently, researchers have begun to examine the influence of genetic factors on peer and family relationships across the pre-adolescent and adolescent time periods. This article introduces the special issue by providing a critical overview of behavior genetic methodology and existing research demonstrating gene-environment processes operating on the link between peer and family relationships and adolescent adjustment. The overview is followed by a summary of new research studies, which use genetically informed samples to examine how peer and family environment work together with genetic factors to influence behavioral outcomes across adolescence. The studies in this special issue provide further evidence of gene-environment interplay through innovative behavior genetic methodological approaches across international samples. Results from the quantitative models indicate environmental moderation of genetic risk for coercive adolescent-parent relationships and deviant peer affiliation. The molecular genetics studies provide support for a gene-environment interaction differential susceptibility model for dopamine regulation genes across positive and negative peer and family environments. Overall, the findings from the studies in this special issue demonstrate the importance of considering how genes and environments work in concert to shape developmental outcomes during adolescence.

    Objective Mounting literature suggests that parental monitoring, risky peer norms, and future orientation correlate with illicit drug use and delinquency. However, few studies have investigated these constructs simultaneously in a single statistical model with low income African American youth. This study examined parental monitoring, peer norms and future orientation as primary pathways to drug use and delinquent behaviors in a large sample of African American urban adolescents. Methods A path model tested direct paths from peer norms, parental monitoring, and future orientation to drug use and delinquency outcomes after adjusting for potential confounders such as age, socioeconomic, and sexual orientation in a sample of 541 African American youth. Results Greater scores on measures of risky peer norms were associated with heightened risk of delinquency with an effect size that was twice in magnitude compared to the protective effects of future orientation. Regarding substance use, greater perceived risky peer norms correlated with the increased likelihood of substance use with a standardized effect size 3.33 times in magnitude compared to the protective effects of parental monitoring. Conclusions Findings from this study suggest that interventions targeting risky peer norms among adolescent African American youth may correlate with a greater impact on reductions in substance use and delinquency than exclusively targeting parental monitoring or future orientation.

    Objective. To compare peer teaching in a medical and a pharmacy clinical teaching unit and to provide suggestions for future research in pharmacy near-peer teaching. Methods. This exploratory observational study used principles of ethnographic methodology for data collection and analysis. Observations were collected in a large downtown teaching hospital. An average of 4-6 hours per day were spent observing a team of medical trainees from the Faculty (School) of Medicine in the general internal medicine (unit for two weeks, followed by a team of pharmacy trainees in an ambulatory hemodialysis (HD) unit for two weeks. Data was collected through field notes and informal interviews that were audiotaped and subsequently transcribed. Data was interpreted by the observer and reviewed weekly by two impartial pharmacists. Results. Five major themes emerged: (1) influence of peer teaching hierarchy; (2) educational distance between peer learners and teachers; (3) effect of the clinical teaching unit size on peer learning; (4) trainees' perception of their teaching role in the clinical teaching unit; and (5) influence of daily schedule and workload on peer teaching. As opposed to pharmacy, a hierarchy and pyramidal structure of peer teaching was observed in medical experiential training. There appeared to be no effect of educational distance on near peer teaching; however, perception of teaching role and influence of daily schedule affected near-peer teaching. Conclusion. Through initial comparisons of medical and pharmacy clinical teaching units, this study provides a reflection of elements that may be necessary to successfully implement near-peer teaching in pharmacy experiential training. Future studies in this area should assess learning outcomes and participant satisfaction, preceptor workload, and impact on patient care.

    Some peer reviewers may inappropriately, or coercively request that authors include references to the reviewers' own work. The objective of this study was to evaluate whether, compared to reviews for a journal with single-blind peer review, reviews for a journal with open peer review included (1) fewer self-citations; (2) a lower proportion of self-citations without a rationale; and (3) a lower ratio of proportions of citations without a rationale in self-citations versus citations to others' work. Peer reviews for published manuscripts submitted in 2012 to a single-blind peer review journal, the Journal of Psychosomatic Research, were previously evaluated (Thombs et al., 2015). These were compared to publically available peer reviews of manuscripts published in 2012 in an open review journal, BMC Psychiatry. Two investigators independently extracted data for both journals. There were no significant differences between journals in the proportion of all reviewer citations that were self-citations (Journal of Psychosomatic Research: 71/225, 32%; BMC Psychiatry: 90/315, 29%; p=.50), or in the proportion of self-citations without a rationale (Journal of Psychosomatic Research: 15/71, 21%; BMC Psychiatry: 12/90, 13%; p=.21). There was no significant difference between journals in the proportion of self-citations versus citations to others' work without a rationale (p=.31). Blind and open peer review methodologies have distinct advantages and disadvantages. The present study found that, in reasonably similar journals that use single-blind and open review, there were no substantive differences in the pattern of peer reviewer self-citations.

    2016-07-01

    This study was designed to assess the impact of a decision-making curriculum (PEER-DM) on the social peer relationship knowledge and self-protective decision-making skills of adolescents with disabilities in hypothetical situations involving negative peer pressure. A randomized design was used to assign students with disabilities from self-contained special education classes to an intervention group (n = 22) or a wait-list control group (n = 20). ANCOVA analyses, using pretest scores as covariates, indicated that students who were trained on PEER-DM had significantly higher effective decision-making action and correct risk perception scores, relative to participants in the control group. This study provides supporting evidence that PEER-DM is a promising intervention for students with disabilities, including those with identified autism spectrum disorders, during transition years to help them develop a better understanding of positive and negative peer relationships and learn systematic decision-making skills for improved handling of social situations in the school and community, especially situations involving negative peer pressure. The study adds credence to using systematic, strategy-based decision making interventions designed to address the cognitive, emotional and motivational processes underlying adolescent decision making in sensitive interpersonal situations involving peer pressure. The study points to the lack of preparedness to handle situations of negative peer pressure as a serious social and health risk for adolescents with disabilities that deserves urgent and concerted attention in transition services programming. Implications for future curriculum-development efforts and replication of treatment findings are discussed. Future research examining disability-specific patterns of decision-making in peer situations and comparisons with typically developing populations is recommended.

    Children not accepted or actively rejected by peers are at greater risk for peer victimization. We examined whether a positive teacher-student relationship can potentially buffer these children from the risk of peer victimization. Participants were 361 elementary school children in the 4th or 5th grade. Peer-report measures were used to assess teacher-student relationship quality (TSRQ), social preference, and rejected sociometric status; peer victimization was assessed via self-, peer-, and teacher-reports. As expected, social preference assessed in the fall semester was a significant negative predictor of self- and peer-reported victimization measured in the spring, controlling for prior levels of peer victimization. TSRQ in the fall was not a significant unique predictor of self-, peer-, or teacher-reported victimization the following spring, controlling for fall victimization and social preference scores. We found a significant interaction between social preference and TSRQ in predicting self-, peer-, and teacher-reported peer victimization: Social preference significantly predicted peer victimization, but only for those children with relatively poor student-teacher relationships. Subgroup analysis revealed that children actively rejected by peers in the fall reported significantly less peer victimization in the spring (controlling for fall victimization scores) when their fall TSRQ scores were at or above the sample mean compared to rejected children whose TSRQ scores were low (i.e., < -0.5 SD below the mean). Findings offer preliminary support for the notion that teacher-student relationship quality can buffer children at social risk for continued peer victimization.

    This paper examined the relative influence of selection and socialization on alcohol and tobacco use in adolescent peer networks and peer groups. The sample included 1419 Finnish secondary education students (690 males and 729 females, mean age 16 years at the outset) from nine schools. Participants identified three school friends and described their alcohol and tobacco use on two occasions one year apart. Actor-based models simultaneously examined changes in peer network ties and changes in individual behaviors for all participants within each school. Multi-level analyses examined changes in individual behaviors for adolescents entering new peer groups and adolescents in stable peer groups, both of which were embedded within the school-based peer networks. Similar results emerged from both analytic methods: Selection and socialization contributed to similarity of alcohol use, but only selection was a factor in tobacco use.

    The longitudinal relationships between two dimensions of peer relationships and subsequent academic adjustment were investigated in a sample of 543 relatively low achieving children (M = 6.57 years at Year 1, 1st grade). Latent variable SEM was used to test a four stage model positing indirect effects of peer acceptance and peer academic reputation (PAR) assessed in Year 2 on academic achievement in Year 5, via the effects of the peer relationships variables on perceived academic competence in Year 3 and effortful engagement in Year 4. As expected, the effect of PAR on engagement was partially mediated by perceived academic competence, and the effect of perceived academic competence on achievement was partially mediated by engagement. In the context of PAR, peer acceptance did not contribute to the mediating variables or to achievement. Findings provide a clearer understanding of the processes by which early peer-relationships influence concurrent and future school-related outcomes. Implications for educational practice and future research are discussed. PMID:21113406

    This study employed an A-B singled subject design to explore the extent to which a peer-mediated intervention supported a first-grade student with autism's usage both in purpose and frequency of a speech-generating device (SGD) during mathematics activities. The intervention involved teaching a peer without a disability to encourage the student with autism to use the SGD during partnered mathematics activities. Our analysis involved visual and descriptive examination of trends and patterns over time, and comparison of means between and within phases. We found during the course of this study that (1) the student with autism's level of overall communication, which included the relevancy of these communicative behaviors, increased; (2) the student with autism's level of spontaneous communication acts increased; and (3) the peer became more independent with supporting the student with autism's communication. Implications for future research and practice are provided.

    Some US prisons are meeting the growing need for end-of-life care through inmate volunteer programs, yet knowledge of the motivations of inmate caregivers is underdeveloped. This study explored the motivations of inmate hospice volunteers from across Louisiana State (n = 75) through an open-ended survey, a grounded theory approach to analysis, and comparison of responses by experience level and gender. Participants expressed complex motivations; Inter-related themes on personal growth, social responsibility and ethical service to vulnerable peers suggested that inmate caregivers experience an underlying process of personal and social transformation, from hospice as a source of positive self-identity to peer-caregiving as a foundation for community. Better understanding of inmate caregiver motivations and processes will help prisons devise effective and sustainable end of life peer-care programs. © The Author(s) 2013.

    Children with mathematical difficulties usually have an impaired ability to process symbolic representations. Functional MRI methods have suggested that early frontoparietal connectivity can predict mathematic achievements; however, the study of brain connectivity during numerical processing remains unexplored. With the aim of evaluating this in children with different math proficiencies, we selected a sample of 40 children divided into two groups [high achievement (HA) and low achievement (LA)] according to their arithmetic scores in the Wide Range Achievement Test, 4th ed.. Participants performed a symbolic magnitude comparison task (i.e. determining which of two numbers is numerically larger), with simultaneous electrophysiological recording. Partial directed coherence and graph theory methods were used to estimate and depict frontoparietal connectivity in both groups. The behavioral measures showed that children with LA performed significantly slower and less accurately than their peers in the HA group. Significantly higher frontocentral connectivity was found in LA compared with HA; however, when the connectivity analysis was restricted to parietal locations, no relevant group differences were observed. These findings seem to support the notion that LA children require greater memory and attentional efforts to meet task demands, probably affecting early stages of symbolic comparison.

    External quality assessment (EQA) with commutable samples is essential for assessing the quality of assays performed by laboratories, particularly when the emphasis is on their standardization status and interchangeability of results. We used a panel of 20 fresh-frozen single-donation serum samples to assess assays for the measurement of creatinine, glucose, phosphate, uric acid, total cholesterol, HDL cholesterol, LDL cholesterol, and triglycerides. The commercial random access platforms included: Abbott Architect, Beckman Coulter AU, Ortho Vitros, Roche Cobas, Siemens Advia, and Thermo Scientific Konelab. The assessment was done at the peer group level and by comparison against the all-method trimmed mean or reference method values, where available. The considered quality indicators were intraassay imprecision, combined imprecision (including sample-matrix interference), bias, and total error. Fail/pass decisions were based on limits reflecting state-of-the-art performance, but also limits related to biological variation. Most assays showed excellent peer performance attributes, except for HDL- and LDL cholesterol. Cases in which individual assays had biases exceeding the used limits were the Siemens Advia creatinine (-4.2%), Ortho Vitros phosphate (8.9%), Beckman Coulter AU triglycerides (5.4%), and Thermo Scientific Konelab uric acid (6.4%), which lead to considerable interassay discrepancies. Additionally, large laboratory effects were observed that caused interlaboratory differences of >30%. The design of the EQA study was well suited for monitoring different quality attributes of assays performed in daily laboratory practice. There is a need for improvement, even for simple clinical chemistry analytes. In particular, the interchangeability of results remains jeopardized both by assay standardization issues and individual laboratory effects. © 2014 The American Association for Clinical Chemistry.

    Background Survivors of pediatric CNS tumors are at risk for persistent tumor/treatment-related morbidity, physical disability and social consequences that may alter self-perception, vital for self-identity, mental health and quality of survival. We studied the long-term impact of childhood CNS tumors and their treatment on the self-perception of adult survivors and compared outcomes with those of the general population. Methods The cohort included 697 Swedish survivors diagnosed with a primary CNS tumor during 1982–2001. Comparison data were randomly collected from a stratified general population sample. Survivors and general population individuals were compared as regards self-perception in 5 domains: body image, sports/physical activities, peers, work, and family, and with a global self-esteem index. Within the survivor group, determinants of impact on self-perception were identified. Results The final analyzed sample included 528 survivors, 75.8% of the entire national cohort. The control sample consisted of 995, 41% of 2500 addressed. Survivors had significantly poorer self-perception outcomes in domains of peers, work, body image, and sports/physical activities, and in the global self-perception measure, compared with those of the general population (all P < .001). Within the survivor group, female gender and persistent visible physical sequelae predicted poorer outcomes in several of the studied domains. Tumor type and a history of cranial radiation therapy were associated with outcomes. Conclusion An altered self-perception is a potential late effect in adult survivors of pediatric CNS tumors. Self-perception and self-esteem are significant elements of identity, mental health and quality of survival. Therefore, care and psychosocial follow-up of survivors should include measures for identifying disturbances and for assessing the need for psychosocial intervention. PMID:25332406

    This study examined the influence of peers in meeting DSM-IV symptom criteria for an internalizing disorder in adolescents exposed to Hurricane Georges. Participants included a representative community sample of 905 youth (N = 476 boys) ages 11-17 residing in Puerto Rico. Data were gathered on hurricane exposure, symptoms of internalizing disorders, peer social support, peer violence, and peer substance use through in-person structured interviews with adolescents and caretakers from 1999-2000 in Puerto Rico, 12-27 months after Hurricane Georges. Hurricane exposure, peer violence, and peer substance use predicted whether adolescents met DSM-IV symptom criteria for a measured internalizing disorder. An interaction was found between hurricane exposure and peer violence, which indicated that hurricane exposure was significantly related to meeting DSM-IV symptom criteria for an internalizing disorder among adolescents who do not report associating with violent peers. However, for participants who reported high levels of peer violence, hurricane exposure did not convey additional risk for meeting DSM-IV symptom criteria for an internalizing disorder. With the increasing role peers play in adolescents’ lives, understanding the influence of peers on the development of internalizing symptoms following hurricane exposure may assist in planning developmentally sensitive response plans.

    When estimating the association between peer and youth alcohol consumption, it is critical to account for possible differential levels of response to peer socialization processes across youth, in addition to variability in individual, family, and social factors. Failure to account for intrinsic differences in youth's response to peers may pose a threat of selection bias. To address this issue, we used a propensity score stratification method to examine whether the size of the association between peer and youth drinking is contingent upon differential predicted probabilities of associating with alcohol-consuming friends. Analyzing a Chilean youth sample (N = 914) of substance use, we found that youths are susceptible to the detrimental role of peer drinkers, but the harmful relationship with one's own drinking behavior may be exacerbated among youth who already have a high probability of socializing with peers who drink. In other words, computing a single weighted-average estimate for peer drinking would have underestimated the detrimental role of peers, particularly among at-risk youths, and overestimated the role of drinking peers among youths who are less susceptible to peer socialization processes. Heterogeneous patterns in the association between peer and youth drinking may shed light on social policies that target at-risk youths.
