The paper examines whether unpopularity and disliking among peers are partially distinct dimensions of adolescents' negative social experience. We recruited 418 students (187 boys, 231 girls, M = 12.12 years, SD = 4.33) from an urban junior high school. These early adolescents completed a peer nomination inventory assessing aspects of their social…

Do academically-engaged adolescents experience social sanctions from the peer group?
Schwartz, David; Kelly, Brynn M; Duong, Mylien T
2013-09-01
Existing theoretical perspectives suggest that adolescents who are characterized by high achievement may experience social sanctions from peers. The central premise is that, in many North American settings, adolescent peer groups are characterized by negative attitudes toward the school environment. To test these hypotheses, we examined associations between indicators of low social power (unpopularity and victimization by peers) and academic competence for 415 adolescents (193 boys; 222 girls) attending an urban high school. This school served neighborhoods that were characterized by a moderate degree of economic distress and the students were predominately of Hispanic American descent. A short-term longitudinal design was used, with two waves of data collected over consecutive school years. The adolescents completed a peer nomination inventory assessing relational and overt victimization by peers, unpopularity, and social rejection. In addition, we obtained math and language arts grades from school records, and we assessed behavioral engagement in school with a self-report inventory. Structural equation models did not reveal a strong pattern of longitudinal change in social standing with peers or academic functioning. However, we found positive correlations between academic achievement and problematic peer relationships in both years of the project. We also found evidence that gender moderates these associations, with the effects reaching significance only for boys. Our results provide evidence that, in some settings, high achieving adolescents can be prone to negative treatment or marginalization by peers.

Social interactions play an important role in our everyday life. Studies on children's quality of life (QoL) show that peer relations are associated with both positive and negative outcomes. Popularity defines the degree to which a child is liked by his or her peers, whereas reciprocal friendship occurs when two children mutually nominate each other as friends. The overall aim was to examine associations between peer relations and children's QoL. Baseline data were from the Health Oriented Pedagogical Project (HOPP). From a sample of 2297, 691 children aged 11-12 years participated. QoL was measured using the Norwegian version of the Inventory of Life Quality in Children and Adolescents (ILC). Popularity and friendship variables were based on number of nominations and represent quantitative features of peer relationships. Both popularity and reciprocal friendship had a positive association with children's QoL. Number of nominations (both for popularity and reciprocal friendship) played a significant role for the above-mentioned associations. Consequently, popularity (β = 0.18) and reciprocal friendship (β = 0.25) were associated with children's QoL with 95% CIs of 0.12-0.27 and 0.17-0.31, respectively. Findings from the current study contribute to contemporary research focused on children's QoL. Being able to rank reciprocal friendships, as well as recognizing that having more than one reciprocal friendship increases QoL, is important and could be beneficial for developing programs that promote high QoL, hence preventing possible maladjustments in a long-term perspective.

This paper reports two prospective investigations of the role of friendship in the relation between peer victimization and grade point averages (GPA). Study 1 included 199 children (105 boys, 94 girls; mean age of 9.1 years) and Study 2 included 310 children (151 boys, 159 girls; mean age of 8.5 years). These children were followed for two school years. In both projects, we assessed aggression, victimization, and friendship with a peer nomination inventory, and we obtained children's GPAs from a review of school records. Peer victimization was associated with academic declines only when children had either a high number of friends who were above the classroom mean on aggression or a low number of friends who were below the classroom mean on aggression. These results highlight the importance of aggression levels among friends for the academic adjustment of victimized children.

This paper presents a prospective investigation focusing on the moderating role of peer victimization on associations between harsh home environments in the preschool years and academic trajectories during elementary school. The participants were 388 children (198 boys, 190 girls) who we recruited as part of an ongoing multisite longitudinal investigation. Preschool home environment was assessed with structured interviews and questionnaires completed by parents. Peer victimization was assessed with a peer nomination inventory that was administered when the average age of the participants was approximately 8.5 years. Grade point averages (GPA) were obtained from reviews of school records, conducted for seven consecutive years. Indicators of restrictive punitive discipline and exposure to violence were associated with within-subject declines in academic functioning over seven years. However, these effects were exacerbated for those children who had also experienced victimization in the peer group during the intervening years. PMID:22506975

This study examined whether social preference was a mechanism that explained the relation between proactive and reactive aggression and peer victimization. Participants were 494 children in grades 2-5. Proactive and reactive aggression was assessed via a self-report measure and indices of social preference and peer victimization were assessed via a peer nomination inventory. Data was collected during the fall and spring of two academic years. The relations among aggression, social preference, and peer victimization varied as a function of aggression and gender. For girls, reactive aggression was a significant negative predictor of social preference. Findings also revealed social preference mediated the relation between reactive aggression and peer victimization for girls. This pathway did not hold for boys. There was some evidence that proactive aggression was negatively associated with peer victimization, but only for girls. Findings from the current study suggest social preference may be a key mechanism through which reactive aggression is associated with future victimization for girls. Boys' aggression was not related to subsequent peer victimization. Future research and intervention efforts should consider gender differences and the function of aggression when investigating children's peer victimization experiences.
Prosocial and antisocial children's perceptions of peers' motives for prosocial behaviours.
Wardle, Georgina A; Hunter, Simon C; Warden, David
2011-09-01
This study investigated whether peer-nominated prosocial and antisocial children have different perceptions of the motives underlying peers' prosocial actions. Eighty-seven children, aged 10-12 years old, completed peer-nomination measures of social behaviour. On the basis of numbers of social nominations received, a subsample of 51 children (32 who were peer-nominated as 'prosocial', and 18 who were peer-nominated as 'antisocial') then recorded their perceptions of peers' motives for prosocial behaviours. Expressed motives were categorized predominantly into three categories, coinciding with Turiel's (1978) 'moral', 'conventional', and 'personal domains'. Results indicate that children's social reputation is associated with the extent to which they perceive peers' prosocial motives as 'personal' or 'moral', with more prosocial children attributing moral motives, and more antisocial children attributing personal motives. Although traditionally Turiel's domain theory has been used to understand 'antisocial' children's behaviour, the current findings suggest that 'prosocial' children's behaviour may also be related to domains of judgment. ©2010 The British Psychological Society.

This study describes a method for using teacher nominations and ratings to identify socially influential, aggressive middle school students for participation in a targeted violence prevention intervention. The teacher nomination method is compared with peer nominations of aggression and influence to obtain validity evidence. Participants were urban, predominantly African American and Latino sixth-grade students who were involved in a pilot study for a large multi-site violence prevention project. Convergent validity was suggested by the high correlation of teacher ratings of peer influence and peer nominations of social influence. The teacher ratings of influence demonstrated acceptable sensitivity and specificity when predicting peer nominations of influence among the most aggressive children. Results are discussed m terms of the application of teacher nominations and ratings in large trials and full implementation of targeted prevention programs. PMID:16378226

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.

In this study, the robustness of the Big Five personality factors in adolescents' self-ratings and peer nominations was investigated. Data were obtained on 2,001 adolescents attending secondary school (885 girls; 1,116 boys; M age = 14.5 years). Exploratory and confirmatory factor analyses on the self-ratings confirmed the Big Five personality factors. In contrast, exploratory analysis on the peer nominations revealed five different factors: Aggression-Inattentiveness, Achievement-Withdrawal, Self-Confidence, Sociability, and Emotionality-Nervousness. It is suggested that peers evaluate group members not in terms of their personality but in terms of their group reputation. Peer evaluations contributed substantially to the prediction of peer acceptance and rejection; the Big Five personality factors based on self-ratings did not.

Associations of popularity with adolescent substance use were examined among 1,793 6th-8th grade students who completed an in-school survey. Popularity was assessed through both self-ratings and peer nominations. Students who scored higher on either measure of popularity were more likely to be lifetime cigarette smokers, drinkers, and marijuana users, as well as past month drinkers. Self-rated popularity was positively associated with past month marijuana use and heavy drinking, and peer-nominated popularity showed a quadratic association with past month heavy drinking. These results extend previous work and highlight that popularity, whether based on self-perceptions or peer friendship nominations, is a risk factor for substance use during middle school. Given the substantial increase in peer influence during early adolescence, prevention program effectiveness may be enhanced by addressing popularity as a risk factor for substance use or working with popular students to be peer leaders to influence social norms and promote healthier choices.

2015-10-01
The perpetration and receipt of electronic aggression have largely been assessed with self-report questionnaires. Using a sample of 573 adolescents, the current study compared the psychometric properties of a peer-nomination measure of electronic aggression and victimization to the more widely used self-report approach. Estimates of the reliability, stability, and concordance of peer- and self-report assessments were adequate, mirroring those from research on aggressive exchanges in school. Analyses of validity and utility revealed that peer-nominations, compared to self-reports, provide overlapping and distinct information on adolescents' social, emotional, and academic adjustment. Overall, these findings provide evidence that peer-nominations are a reliable, valid, and useful means for measuring electronic aggression and victimization. Future work will benefit from their incorporation into multi-method assessments. Copyright © 2015 The Foundation for Professionals in Services for Adolescents. Published by Elsevier Ltd.

This longitudinal study examined the prospective relations between 713 elementary students’ individual peer teacher support reputation (PTSR) and a measure of the classroom-wide dispersion of peer nominations of teacher support (Centralization of Teacher Support) on students’ peer relatedness (i.e., peer acceptance and peer academic reputation) and academic motivation (i.e., academic self-efficacy and teacher-rated behavioral engagement). PTSR was measured as the proportion of classmates who nominated a given student on a descriptor of teacher-student support. Centralization of Teacher Support was assessed using social network analysis to identify the degree to which peer nominations of teacher support in a classroom centered on a few students. PTSR predicted changes in all student outcomes, above academic achievement and relevant covariates. Centralization of Teacher Support predicted changes in students’ peer academic reputation, net the effect of PTSR and covariates. Students’ academic achievement moderated effects of PTSR and Centralization of Teacher Support on some outcomes. Findings highlight the importance of peers’ perceptions of teacher support and of the structure of those perceptions for children’s social and academic outcomes. Implications for practice are discussed. PMID:24930822

2012-01-01
Purpose The goal of this study is to better understand the longitudinal cross-lagged associations between popularity, assessed through self-rating and peer nominations, and alcohol use among middle school students. Methods The analytic sample is 1,835 6th–8th grade students who were initially recruited from three California middle schools and surveyed in the fall and spring semesters of two academic years. Students reported on their background characteristics, past month alcohol use, and perceived popularity. Additionally, students provided school-based friendship nominations, which were used to calculate peer-nominated popularity. A cross-lagged regression approach within a structural equation modeling framework was used to examine the longitudinal relationship between popularity (self-rated and peer-nominated) and alcohol use. Results There was a statistically significant (p = 0.024) association between peer-nominated popularity and the probability of alcohol consumption at the subsequent survey, but not vice versa. Our results suggest that in a scenario where 8% of students are past month drinkers, each increase of 5 friendship nominations is associated with a 30% greater risk of being a current drinker at the next wave. We found no evidence of longitudinal associations between past month alcohol consumption and self-rated popularity. Conclusions Popularity is a risk factor for drinking during the middle school years, with peer-nominated popularity being more predictive of use than self-perceptions of popularity. To inform alcohol prevention efforts for middle school students, additional research is needed to better understand why adolescents with a larger number of school-based friendship ties are more inclined to drink.

This study examined the moderating role of classroom injunctive norms salience regarding social withdrawal and regarding aggression in the longitudinal association between these behaviors and peer victimization. A total of 1,769 fourth through sixth graders (895 girls, M = 10.25 years, SD = 1.03) from 23 schools (67 classrooms) completed a peer nomination inventory in the fall (T1) and spring (T2) of the same academic year. Participants circled the name of each student who fit the description provided for social withdrawal, aggression, and peer victimization at T1 and T2. The salience of injunctive norms was sex-specific and operationalized by the extent to which children displaying the behavior were socially rewarded or sanctioned by their classmates. Generalized estimation equations (GEE) showed that the association between social withdrawal at T1 and peer victimization at T2 was moderated by injunctive norms. Social withdrawal at T1 was positively associated with peer victimization at T2 in classrooms where injunctive norms for this behavior were salient and unfavorable, as well as in classrooms where injunctive norms for aggression were salient and favorable, albeit for girls only. The association between aggression at T1 and peer victimization at T2 was also moderated by the injunctive norms regarding this behavior. Aggressive children were less likely to be victimized in classrooms where this behavior was rewarded. These results support bullying interventions that target factors related to the larger peer context, including social norms. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

2016-09-25
We investigated relationships between Chinese children's imaginary companions (ICs) and peer relationships and social competence in 160 children, aged 5-6 years old. Children and their mothers participated in the interviews regarding the details of the children's ICs, including the type of the companion and the quality of the child-IC relationship. Peer relationships were assessed using sociometric nomination and perceived popularity nomination. Teachers rated children's social competence. Here, 55 children (34.3%) were deemed to have engaged in imaginary companion play. There was no relationship between imaginary companion types and child-IC relationship qualities. Children with invisible friends received more positive nominations than children with personified objects. Children with egalitarian relationships received more positive nominations and popularity nominations, but fewer negative nominations and unpopularity nominations than children with hierarchical relationships. Compared with children with hierarchical relationships, teachers rated the children with egalitarian relationships higher in social competence. The results suggest that imaginary companion types and relationship qualities may represent different dimensions of imaginary companions, calling attentions to the different mechanisms underlying imaginary companion types and relationship qualities with respect to social functioning. © 2016 International Union of Psychological Science.

Adolescents experience various forms of strain in their lives that may contribute jointly to their engagement in cyber aggression. However, little attention has been given to this idea. To address this gap in the literature, the present longitudinal study examined the moderating influence of peer rejection on the relationship between cyber victimization at Time 1 (T1) and subsequent cyber aggression at Time 2 (T2; 6 months later) among 261 (150 girls) 6th, 7th, and 8th graders. Our findings indicated that both peer rejection and cyber victimization were related to T2 peer-nominated and self-reported cyber aggression, both relational and verbal, after controlling for gender and T1 cyber aggression. Furthermore, T1 cyber victimization was related more strongly to T2 peer-nominated and self-reported cyber aggression at higher levels of T1 peer rejection. These results extend previous findings regarding the relationship between peer rejection and face-to-face aggressive behaviors to the cyber context. In addition, our findings underscore the importance of utilizing multiple methods, such as peer-nomination and self-report, to assess cyber aggression in a school setting.

Personalized normative feedback is a recommended component of alcohol interventions targeting college students. However, normative data are commonly collected through campus-based surveys, not through actual participant-referent relationships. In the present investigation, we examined how misperceptions of residence hall peers, both overall using a global question and those designated as important peers using person-specific questions, were related to students' personal drinking behaviors. Participants were 108 students (88% freshman, 54% White, 51% female) residing in a single campus residence hall. Participants completed an online baseline survey in which they reported their own alcohol use and perceptions of peer alcohol use using both an individual peer network measure and a global peer perception measure of their residential peers. We employed network autocorrelation models, which account for the inherent correlation between observations, to test hypotheses. Overall, participants accurately perceived the drinking of nominated friends but overestimated the drinking of residential peers. Consistent with hypotheses, overestimating nominated friend and global residential peer drinking predicted higher personal drinking, although perception of nominated peers was a stronger predictor. Interaction analyses showed that the relationship between global misperception and participant self-reported drinking was significant for heavy drinkers, but not non-heavy drinkers. The current findings explicate how student perceptions of peer drinking within an established social network influence drinking behaviors, which may be used to enhance the effectiveness of normative feedback interventions.

The impact of contact on students' attitudes towards peers with disabilities.
Schwab, Susanne
2017-03-01
This study aimed to understand the relationship between contact with peers with Special Educational Needs (SEN) and students' attitudes towards their peers with SEN, by examining the inter-group contact theory in regular and inclusive classes. A total of 463 students in 8th grade, with a mean age of 14.42 years, from 25 secondary school classes in Styria (Austria) completed a self-report questionnaire regarding their contact with peers with SEN and their attitudes towards peers with disabilities. Contact was indicated by nominations for joint activities and examined in inclusive and regular classes. The German short version of the Chedoke-McMaster Attitudes towards Children with Handicaps scale (CATCH; Schwab, 2015b; Rosenbaum et al., 1986) was used to measure students' attitudes towards peers with learning disabilities and emotional disorders. Students with SEN are less frequently nominated by their peers for joint activities, such as working together on a school project. Students from inclusive and regular classes did not differ in their attitudes towards peers with SEN. However, those students who nominated at least one peer with SEN for a joint activity had more positive attitudes towards peers with disabilities. Freely choosing contact with a peer with SEN was associated with more positive attitudes towards disability while simply attending the same class may have no effect or even a negative impact on students' attitudes.

Women who start college in one of the natural or physical sciences leave in greater proportions than their male peers. The reasons for this difference are complex, and one possible contributing factor is the social environment women experience in the classroom. Using social network analysis, we explore how gender influences the confidence that college-level biology students have in each other’s mastery of biology. Results reveal that males are more likely than females to be named by peers as being knowledgeable about the course content. This effect increases as the term progresses, and persists even after controlling for class performance and outspokenness. The bias in nominations is specifically due to males over-nominating their male peers relative to their performance. The over-nomination of male peers is commensurate with an overestimation of male grades by 0.57 points on a 4 point grade scale, indicating a strong male bias among males when assessing their classmates. Females, in contrast, nominated equitably based on student performance rather than gender, suggesting they lacked gender biases in filling out these surveys. These trends persist across eleven surveys taken in three different iterations of the same Biology course. In every class, the most renowned students are always male. This favoring of males by peers could influence student self-confidence, and thus persistence in this STEM discipline. PMID:26863320

Weight-based stigma compromises the social networks of overweight children. To date, research on the position of overweight children in their peer network has focused only on friendship relations, and not on negative relationship dimensions. This study examined how overweight was associated with relations of friendship and dislike (antipathies) in the peer group. Exponential random graph models (ERGM) were used to examine friendship and antipathy relations among overweight children and their classmates, using a sub-sample from the TRacking Adolescents' Individual Lives Survey (N = 504, M age 11.4). Findings showed that overweight children were less likely to receive friendship nominations, and were more likely to receive dislike nominations. Overweight children were also more likely than their non-overweight peers to nominate classmates that they disliked. Together, the results indicate that positive and negative peer relations are impacted by children's weight status, and are relevant to addressing the social marginalization of overweight children.

Adolescent peer-aggression has recently been considered from the evolutionary perspective of intrasexual competition for mates. We tested the hypothesis that peer-nominated physical aggression, indirect aggression, along with self-reported bullying behaviors at Time 1 would predict Time 2 dating status (one year later), and that Time 1 peer- and self-reported peer victimization would negatively predict Time 2 dating status. Participants were 310 adolescents who were in grades 6 through 9 (ages 11-14) at Time 1. Results showed that for both boys and girls, peer-nominated indirect aggression was predictive of dating one year later even when controlling for age, peer-rated attractiveness, and peer-perceived popularity, as well as initial dating status. For both sexes, self-reported peer victimization was negatively related to having a dating partner at Time 2. Findings are discussed within the framework of intrasexual competition.

Recent work has reported adverse effects of students' stuttering on their social and emotional functioning at school. Yet, few studies have provided an in-depth examination of classroom interaction of students who stutter (SWS). The current study uses a network perspective to compare acceptance and rejection in the classroom interaction between SWS and their peers in secondary education. The sample comprised 22 SWS and 403 non-stuttering peers (22 classes) of secondary education in Flanders (Belgium). Students' nominations regarding three acceptance and three rejection criteria were combined. Social network analysis offered procedures that considered direct and indirect interaction between all classmates. We found few significant differences: SWS and their peers were distributed similarly across positive and negative status groups. Both considered and were considered by, on average, six or seven classmates as 'a friend', who they liked and could count on, and nominated or were nominated by one or two classmates as 'no friend', somebody who they disliked and could not count on. On average, SWS and their classmates also did not differ in terms of structural position in the class group (degree, closeness and betweenness), reciprocated rejection, and clique size. However, SWS do tend to be slightly more stringent or more careful in nominating peers, which led to fewer reciprocated friendships. Our results suggest that SWS are quite accepted by peers in secondary education in Flanders. Such positive peer interaction can create a supportive and encouraging climate for SWS to deal with specific challenges. Copyright © 2017 Elsevier Inc. All rights reserved.

The Role of Friendship Reciprocity in University Freshmen's Alcohol Consumption.
Giese, Helge; Stok, F Marijn; Renner, Britta
2017-07-01
The similarity of friends in the frequency and quantity of alcohol consumption is explored. During their first semester, 57 psychology freshmen indicated weekly drinking frequency and quantity and nominated the three peers of this group they liked most. These nominations were then used to derive the weekly alcohol consumption of friends that either did or did not reciprocate a nomination. Multilevel modeling of weekly variations showed that individuals' drinking frequency was similar to peers who reciprocated a friendship (b = 0.15, p = .001), but not to non-reciprocating peers (b = -0.01, p = .720). In contrast, weekly variation in quantity of individual students' drinking was similar to both reciprocating (b = 0.11, p = .018) and non-reciprocating peers' drinking (b = 0.10, p = .014). Yet across all weeks, quantity tended only to be similar to non-reciprocating peers (b = 0.49, p = .020). Freshmen might spend drinking time with peers who reciprocate a friendship, but are similar regarding the quantity of drinks consumed to all people they find interesting. Thus, alcohol consumption is used strategically for social purposes. This social purpose should also be acknowledged in alcohol-reduction interventions. © 2017 The International Association of Applied Psychology.
Peer associations for substance use and exercise in a college student social network.

Substance use and exercise have opposite trajectories in young adulthood, and research indicates that peers are influential for both of these health behaviors, but simultaneous investigations of peer associations with substance use and exercise have not been conducted. Use a college residence hall peer network to examine associations between peer behaviors and alcohol use, marijuana use, and exercise behavior. 129 undergraduates (51.9% female, 48.1% non-Hispanic White; 84.5% first-year students) in one residence hall completed a Web-based survey of substance use and exercise and identified up to 10 students in the residence hall who were important to them. Two social network analytic methods, community detection cluster analysis and network autocorrelation modeling, were used to identify peer groupings and to examine the associations between peer and participant behaviors, respectively. Participants nominated an average of 4.1 residence hall members, and 53.9% of the ties were reciprocal. 6 clusters were identified that differed significantly on demographics, college activities, substance use, and exercise. Weekly volume of alcohol consumed among nominated peers was significantly associated with that of participants, and all other covariates, including gender and athlete status, were not significant. Peer marijuana use also was associated with participant use after controlling for covariates. Exercise levels of nominated peers were not associated with exercise levels of participants. College student networks may be good targets for health-related prevention programs. Programs that use close-proximity peers to influence the behavior of others might be more effective with substance use as the target behavior than exercise.
The outcast-lash-out effect in youth: alienation increases aggression following peer rejection.
Reijntjes, Albert; Thomaes, Sander; Bushman, Brad J; Boelen, Paul A; de Castro, Bram Orobio; Telch, Michael J
2010-10-01
Although there are good theoretical reasons to believe that youth who are high in alienation (i.e., estranged from society, significant others, and themselves) are prone to behave aggressively, empirical evidence is lacking. The present experiment tested whether alienation moderates the effects of acute peer rejection on aggression in youth. Participants (N = 121; mean age = 11.5 years) completed a personal profile (e.g., "How do you describe yourself?") that was allegedly evaluated online by a panel of peer judges. After randomly receiving negative or positive feedback from peer judges, participants were given the opportunity to aggress against them (i.e., by reducing their monetary reward and by posting negative comments about them online). As predicted, alienation increased participants' aggression against peers who had rejected them, but not against peers who had praised them, even after controlling for peer-nominated chronic rejection and peer-nominated aggression. Thus, alienated youth are more aggressive than others when they experience acute peer rejection.

Background Research suggests that the growing prevalence of obesity may be related to the influence of the health behaviours of peers. We look at clustering of exercise and eating behaviours amongst a previously unstudied group, young adults in Sweden. Previous research has mainly been conducted in the United States and Britain, countries that have relatively high rates of obesity. Methods Using ego-alter dyads from the egocentric network data as the unit of analysis, we conduct logistic regressions to investigate the association between ego and alter exercise and eating behaviours. Results Respondents have a significantly greater probability of engaging in regular exercise and eating healthily if a nominated peer also does so. Furthermore, the degree to which this behavior is shared is modulated by the strength of the relationship between the two individuals, with a greater probability of engaging in these behaviours observed when the relationship with the nominated peer is strong relative to when the relationship is weak. However, we find that ego-alter homogeneity in terms of gender and migration status was not associated with a significantly greater probability of behaving in a similar manner to a nominated peer. Furthermore, the status of the nominated peer as a relative or not did not impact the probability that the ego would engage in similar health behaviours to that alter. Conclusions We observe strong associations between ego and alter health behaviours for young adults, consistent with previous research. Although we cannot draw causal inferences, these results suggest that the health behaviours of an individual’s peers may play a role in shaping their own health behaviours. PMID:23981951

There is a plethora of research showing that empathy promotes prosocial behavior among young people. We examined a relatively new construct in the mindfulness literature, nonattachment, defined as a flexible way of relating to one's experiences without clinging to or suppressing them. We tested whether nonattachment could predict prosociality above and beyond empathy. Nonattachment implies high cognitive flexibility and sufficient mental resources to step out of excessive self-cherishing to be there for others in need. Multilevel Poisson models using a sample of 15-year olds (N = 1831) showed that empathy and nonattachment independently predicted prosocial behaviors of helpfulness and kindness, as judged by same-sex and opposite-sex peers, except for when boys nominated girls. The effects of nonattachment remained substantial in more conservative models including self-esteem and peer nominations of liking. PMID:25852590

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. PMID:20378125

This study examines whether prosocial behavior and personality have independent or overlapping associations with adolescent externalizing problems. A total of 128 female and 103 male early adolescents (M = 13.6 years old) completed personality inventories. Prosocial behavior was assessed by peer nominations (N = 663). Composite aggression and delinquency scores were derived from maternal and self-reports. Path analyses indicated gender differences in patterns of association. For girls, links between prosocial behavior and both aggression and delinquency were fully mediated by agreeableness and partially mediated by conscientiousness. For boys, prosocial behavior, agreeableness, and conscientiousness were independently and negatively associated with aggression and delinquency. The findings suggest that personality and prosocial behavior are uniquely related to boys’ behavior problems but cannot be readily disentangled when it comes to girls’ behavior problems.

Peer status is an important aspect of adolescents' social lives and is pursued actively by them. Although extensive research has examined how social behaviors are related to peer status (e.g., social preference, popularity), little attention has been given to adolescents' social goals to obtain a desired peer status. Thus, this study examined two types of social status goals, popularity goal and social preference goal, and their relationships to social status insecurity and social behaviors among 405 ethnically diverse early adolescents (267 girls; M age = 12.92 years; age range = 11-15 years). After accounting for adolescents' attained peer statuses (popularity and social preference), both social status goals were related distinctly to aggressive and prosocial behaviors as measured by self reports and peer nominations. Specifically, higher endorsement of the popularity goal was related to more self-reported relational aggression, but less peer-nominated prosocial behavior. In contrast, higher endorsement of the social preference goal was linked to less self-reported overt and relational aggression, but more self-reported and peer-nominated prosocial behavior. In addition, this study reveals that adolescents' social status insecurity was related positively to both social status goals and had an indirect effect on adolescents' social behaviors through the mediation of popularity goal endorsement. There were variations in goal endorsement as shown by groups of adolescents endorsing different levels of each goal. The group comparison results on social behaviors were largely consistent with the correlational findings. This study provides new insights into adolescents' social cognitive processes about peer status and the implications of the two social status goals on adolescents' behavioral development.
Logistical Challenges and Opportunities for Conducting Peer Nomination Research in Schools.
Mayeux, Lara; Kraft, Caroline
2017-09-01
Although conducting psychological research within schools has always required effort, persistence, and the careful navigation of various interests, there is a consensus among child and adolescent researchers that, over the past 2 decades, it has become increasingly difficult to collect data within schools. In this chapter, we lay out common and consistent difficulties, frustrations, and obstacles that researchers face when attempting to conduct peer nomination research in schools. Many of these difficulties are faced not only by researchers conducting peer nominations but by any investigator attempting to do school-based research, and we discuss these issues more broadly. We also focus on the specific challenges associated with sociometric methods. We present suggestions and solutions for overcoming these issues and consider ways that researchers can give back to schools and establish long-term partnerships that benefit the students, teachers, and administrators of participating schools, as well as the researchers themselves. Such partnerships have the potential to make data collection easier and to open doors to new research opportunities. © 2017 Wiley Periodicals, Inc.

This study investigated the predictive relations between externalizing behavior, peer preference and friendship quantity, and bully status and victim status among children becoming acquainted with one another for the first time. Children ages 6.8-9.8 years (24 with Attention-Deficit/Hyperactivity Disorder; 113 typically developing; 72 girls) attended a 2-week summer day camp grouped into same-age, same-sex classrooms with previously unacquainted peers. Externalizing behavior (via parent and teacher ratings) was measured before the start of camp; peer preference and friendship quantity (via peer nominations) were measured in the middle of camp, and bully status and victim status (via peer nominations) were measured at the end of camp. Low peer preference mediated the positive association between externalizing behavior and bully status. Both peer preference and friendship quantity moderated the relation between externalizing behavior and bully status as well as between externalizing behavior and victim status; whereas high peer preference protected against both bully status and victim status, friendship quantity protected against victim status but exacerbated bully status. Some gender differences were found within these pathways. Peer preference, compared to friendship quantity, appears to have a more consistently protective role in the relation between externalizing behavior and bully status as well as victim status.

[Adaptation of a peer pressure scale in French and German: the Peer Pressure Inventory].
Baggio, S; Studer, J; Daeppen, J-B; Gmel, G
2013-06-01
Peer pressure is regarded as an important determinant of substance use, sexual behavior and juvenile delinquency. However, few peer pressure scales are validated, especially in French or German. Little is known about the factor structure of such scales or the kind of scale needed: some scales takes into account both peer pressure to do and peer pressure not to do, while others consider only peer pressure to do. The aim of the present study was to adapt French and German versions of the Peer Pressure Inventory, which is one of the most widely used scales in this field. We considered its factor structure and concurrent validity. Five thousand eight hundred and sixty-seven young Swiss men filled in a questionnaire on peer pressure, substance use, and other variables (conformity, involvement) in a cohort study. We identified a four-factor structure, with the three factors of the initial Peer Pressure Inventory (involvement, conformity, misconduct) and adding a new one (relationship with girls). A non-valued scale (from no peer pressure to peer pressure to do only) showed stronger psychometric qualities than a valued scale (from peer pressure not to do to peer pressure to do). Concurrent validity was also good. Each behavior or attitude was significantly associated with peer pressure. Peer pressure seems to be a multidimensional concept. In this study, peer pressure to do showed the strongest influence on participants. Indeed, peer pressure not to do did not add anything useful. Only peer pressure to do affected young Swiss men's behaviors and attitudes and was reliable. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

This study was designed to develop an inventory to measure peer violence among early teens (13-15 years of age) in schools in Sri Lanka. Development of SLETVI was carried out in two phases. In phase I, development of an operational definition for peer violence, identification, and finalizing violent acts for inventory was done by a combination of qualitative methods: a comprehensive literature review, focus group discussions among 13-15-year-old adolescents, their teachers and parents, and consultative meetings with experts in the field. Inventory was then pretested. In phase II, elaboration of SLETVI was carried out by administering it to a sample of 1700 adolescents (13-15 years old). Exploratory factor analysis using principal component analysis was performed separately for experiences of victimization and perpetration. Test-retest reliability of SLETVI was assessed. SLETVI included 37 items in three factors: "less severe violence," "severe physical," and "severe relational" violence. Combined use of qualitative and quantitative methods enabled development of a culturally valid and reliable operational inventory to assess early teenagers' peer violence in Sri Lankan and other South Asian schools.

2015-01-01
Resource Control Theory conceptualizes aggression as a behavior that allows access to, and control of, limited resources (P. H. Hawley, 1999 ). This study investigated the associations of adolescents' indirect aggression with their resource control goals, or goals related to controlling social resources such as dating opportunities and peer status, and with their levels of popularity and social intelligence. Participants were 109 seventh-graders (52% girls) who completed a resource control goals measure, the Tromsø Social Intelligence Scale, and peer nominations of popularity and indirect aggression. Results indicated positive associations between resource control goals and peer-nominated indirect aggression, with popularity further moderating these associations. These findings suggest that the resource control goals of adolescents can be a motivating force to engage in hurtful behaviors. They provide a context from which peer relations researchers can improve their understanding and prevention of adolescents' indirect aggression.

This study had three goals. First, we examined the prevalence of the participant roles of bullying in middle adolescence and possible gender differences therein. Second, we examined the behavioral and status characteristics associated with the participant roles in middle adolescence. Third, we compared two sets of criteria for assigning students to the participant roles of bullying. Participants were 1,638 adolescents (50.9% boys, M(age) = 16.38 years, SD =.80) who completed the shortened participant role questionnaire and peer nominations for peer status and behavioral characteristics. Adolescents were assigned to the participant roles according to the relative criteria of Salmivalli, Lagerspetz, Björkqvist, Österman, and Kaukiainen (1996). Next, the students in each role were divided in two subgroups based on an additional absolute criterion: the Relative Only Criterion subgroup (nominated by less than 10% of their classmates) and the Absolute & Relative Criterion subgroup (nominated by at least 10% of their classmates). Adolescents who bullied or reinforced or assisted bullies were highly popular and disliked and scored high on peer-valued characteristics. Adolescents who were victimized held the weakest social position in the peer group. Adolescents who defended victims were liked and prosocial, but average in popularity and peer-valued characteristics. Outsiders held a socially weak position in the peer group, but were less disliked, less aggressive, and more prosocial than victims. The behavior and status profiles of adolescents in the participant roles were more extreme for the Absolute & Relative Criterion subgroup than for the Relative Only Criterion subgroup. © 2015 Wiley Periodicals, Inc.

Youth in early adolescence are highly concerned with being popular in the peer group, but the desire to be popular can have maladaptive consequences for individuals. In fact, qualitative work suggests that youth with high popularity goals who are nonetheless unpopular have negative experiences with their peers. However, little quantitative work has examined this possibility. The purpose of the current study was to examine if popularity goals were linked with physical (e.g., being hit) and relational (e.g., being excluded) victimization and peer rejection, particularly for individuals who strived for popularity but were viewed by their peers as unpopular. Late elementary and early middle school participants (N = 205; 54% female) completed self-reports of popularity goals and peer nominations of popularity and peer rejection. Teachers reported on students' experiences of relational and physical victimization. Peer nominated popularity and gender were moderators of the association between popularity goals and negative peer experiences. Consistent with hypotheses, girls who were unpopular but wanted to be popular were more likely to experience peer rejection and relational victimization. Unexpectedly, boys who were unpopular but did not desire to be popular were more likely to be rejected and relationally victimized. The findings suggest that intervention and prevention programs may benefit from addressing the social status goals of low status youth in a gender-specific manner.
The development of children's strategies for the social control of emotion.
McCoy, C L; Masters, J C
1985-10-01
It has been shown that young children can recognize emotional states in their peers, that they understand many of the antecedents of emotion, and they are motivated to change negative emotional states in others. The present study examined children's ability to nominate strategic social action that would alter the ongoing emotional state of a peer. Children of 3 ages--5, 8, and 12 years of age--viewed a picture of a young child actually experiencing happiness, sadness, anger, or in a neutral state. In a portion of instances, information was also provided about the social or nonsocial experience that led to the target child's state. The strategies children nominated fell into a small set of agonistic (nurturant) and antagonistic (aggressive) behaviors intended to change positive or negative states. With increasing age, children tended to nominate a greater proportion of verbal strategies, social strategies (with the exception of strategies nominated to change anger), and strategies that directly addressed the cause of another's emotional state.

This study was designed to develop an inventory to measure peer violence among early teens (13–15 years of age) in schools in Sri Lanka. Development of SLETVI was carried out in two phases. In phase I, development of an operational definition for peer violence, identification, and finalizing violent acts for inventory was done by a combination of qualitative methods: a comprehensive literature review, focus group discussions among 13–15-year-old adolescents, their teachers and parents, and consultative meetings with experts in the field. Inventory was then pretested. In phase II, elaboration of SLETVI was carried out by administering it to a sample of 1700 adolescents (13–15 years old). Exploratory factor analysis using principal component analysis was performed separately for experiences of victimization and perpetration. Test-retest reliability of SLETVI was assessed. SLETVI included 37 items in three factors: “less severe violence,” “severe physical,” and “severe relational” violence. Combined use of qualitative and quantitative methods enabled development of a culturally valid and reliable operational inventory to assess early teenagers' peer violence in Sri Lankan and other South Asian schools.

Affective associations with negativity: Why popular peers attract youths' visual attention.
Lansu, Tessa A M; Troop-Gordon, Wendy
2017-10-01
Visual attention to high-status peers is well documented, but whether this attentional bias is due to high-status individuals' leadership and prosocial characteristics or due to their more agonistic behaviors has yet to be examined. To identify the affective associations that may underlie visual attention for high-status versus low-status peers, 122 early adolescents (67 girls; M age =11.0years, SD=0.7) completed a primed attention paradigm. Visual attention was measured using eye tracking as participants looked simultaneously at photographs of two classmates: one nominated by peers as popular and one nominated by peers as unpopular. Prior to each trial, the early adolescents were presented with a positive prime, the word "nice"; a negative prime, the word "stupid"; or no prime. Primary analyses focused on first-gaze preference and total gaze time The results showed a stronger first gaze preference for popular peers than for unpopular peers in the no-prime and negative prime trials than in the positive prime trials. The visual preference for a popular peer, thus, was attenuated by the positive prime. These findings are consistent with the notion that youths may visually attend to high-status peers due to their association with more negative characteristics and the threat they may pose to youths' own social standing and ability to gain interpersonal resources.

Unique associations between peer relations and social anxiety in early adolescence.
Flanagan, Kelly S; Erath, Stephen A; Bierman, Karen L
2008-10-01
This study examined the unique associations between feelings of social anxiety and multiple dimensions of peer relations (positive peer nominations, peer- and self-reported peer victimization, and self-reported friendship quality) among 383 sixth- and seventh-grade students. Hierarchical regression analysis provided evidence for the unique contribution made by peer relations to social anxiety above that made by adolescents' individual vulnerabilities (i.e., teacher ratings of social behavior, self-reported social appraisals assessed by hypothetical vignettes). Two subgroups of socially anxious adolescents--those with and without peer problems--were distinguished by their social behavior but not their social appraisals.

Social Networks and Risk for Depressive Symptoms in a National Sample of Sexual Minority Youth
Hatzenbuehler, Mark L.; McLaughlin, Katie A.; Xuan, Ziming
2012-01-01
The aim of the study was to examine the social networks of sexual minority youths and to determine the associations between social networks and depressive symptoms. Data were obtained from the National Longitudinal Study of Adolescent Health (Add Health), a nationally representative cohort study of American adolescents (N=14,212). Wave 1 (1994–1995) collected extensive information about the social networks of participants through peer nomination inventories, as well as measures of sexual minority status and depressive symptoms. Using social network data, we examined three characteristics of adolescents’ social relationships: (1) social isolation; (2) degree of connectedness; and (3) social status. Sexual minority youths, particularly females, were more isolated, less connected, and had lower social status in peer networks than opposite-sex attracted youths. Among sexual minority male (but not female) youths, greater isolation as well as lower connectedness and status within a network were associated with greater depressive symptoms. Moreover, greater isolation in social networks partially explained the association between sexual minority status and depressive symptoms among males. Finally, a significant 3-way interaction indicated that the association between social isolation and depression was stronger for sexual minority male youths than non-minority youths and sexual minority females. These results suggest that the social networks in which sexual minority male youths are embedded may confer risk for depressive symptoms, underscoring the importance of considering peer networks in both research and interventions targeting sexual minority male adolescents.

Are early adolescent victims of peer-directed aggression youth who hold prominent positions in the social hierarchy or those who are socially marginalized? The present study tackles this question by testing for linear and curvilinear relationships between social network prestige and physical and relational forms of peer victimization for boys and girls. Participants were 952 middle schoolers (age range = 10-14 years; 49.9 % girls; 44 % Latino). Participants nominated victims and friends; friendship nominations were used to calculate social network prestige. Both hypotheses received support, with variation by gender. Girls high in social network prestige were highly victimized. For boys, those both high and low in social network prestige were highly victimized, whereas those at mid-levels of social network prestige were low in victimization. The findings are discussed in relation to a social dominance model of peer-directed aggression, and the practical implications are discussed in relation to protecting youth who are frequent targets of peer victimization.

Getting along with peers becomes increasingly important to health and well-being during early adolescence (10-14 years). Young adolescents may succeed with peers when they are well-liked by and popular among the larger peer group (or at the group-level of social complexity). They might also fare well with peers when they are able to form numerous mutual and high quality friendships (at the dyadic-level of social complexity). Theory emphasizes the interrelatedness of different types of peer experiences, but few longitudinal studies have examined the interplay among and between group- and dyadic-level peer experiences in the same study. As a result, it is not known whether group-level peer experiences are predictors of dyadic-level peer experiences, and/or vice versa. To address this limitation, this study examined the prospective and reciprocal relations between four indices of peer experiences, preference (or being highly liked and not disliked by peers), popularity (or having a reputation as popular), friendship quantity (or having many mutual friends), and friendship or relationship quality, during early adolescence. Participants were 271 adolescents (49% girls; M age = 11.52 years) who completed peer nominations of preference and popularity, a self-report measure of friendship quality, and nominated friends at two waves (Wave 1: November, Grade 6; Wave 2: October, Grade 7). Structural equation modeling indicated that friendship quantity predicted increases in preference and popularity and that friendship quality predicted increases in friendship quantity. Initial popularity was associated with decreases in preference. The importance of these findings for future research is discussed along with study limitations.

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.

Parent-youth and peer relationship inventories based on attachment theory measure communication, trust, and alienation, yet sibling relationships have been overlooked. We developed the Sibling Attachment Inventory and evaluated its psychometric properties in a sample of 172 youth ages 10-14 years. We adapted the 25-item Sibling Attachment Inventory from the Inventory of Parent and Peer Attachment-Revised peer measure. Items loaded onto three factors, identified as communication, trust, and alienation, α = 0.93, 0.90, and 0.76, respectively. Sibling trust and alienation correlated with depression (r s = -0.33, r s = 0.48) and self-worth (r s = 0.23; r s = -0.32); sibling trust and alienation correlated with depression after controlling for parent trust and parent alienation (r s = -0.23, r s = 0.22). Preliminary analyses showed good internal consistency, construct validity, and incremental predictive validity. Following replication of these properties, this measure can facilitate large cohort assessments of sibling attachment.

There is a small, but growing, body of research investigating peer-victimisation between preschoolers, an age which has been identified as being important both theoretically and practically for the development of interventions. This study compares aggressive and defending behaviour and victim status of preschoolers in three European countries; England, Spain and Italy. The results provide further confirmation that some children behave aggressively towards their peers during preschool in each of the countries studied. There are similarities between preschool children involved in peer-victimisation in the three countries in terms of the roles taken, sex differences and the types of aggressive behaviours used and experienced by the children. There were differences in the profiles of children identified as taking the roles by teachers and peers. Overall, it was found that those children identified by peers or teachers as being aggressive were more likely to be male, rated as physically strong and more likely to be rejected by classmates. Also, in general, the targets of peer-victimisation differed depending on the reporter. Peer-nominated victims were not identifiable in terms of gender, popularity or physical strength. Teacher-nominated victims were more likely to be socially rejected and physically weak. There are several subtle differences between the countries which deserve further investigation. The findings are discussed in relation to furthering our understanding of the development of peer-victimisation in preschools and the need for interventions which address this phenomenon.

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.

Hatzenbuehler, Mark L; McLaughlin, Katie A; Xuan, Ziming
2015-01-01
Objective: The purpose of this study was to examine whether the composition of social networks contributes to sexual orientation disparities in substance use and misuse. Method: Data were obtained from the National Longitudinal Study of Adolescent Health (Add Health), a nationally representative cohort study of adolescents (N = 20,745). Wave 1 collected extensive information about the social networks of participants through peer nomination inventories. Results: Same- and both-sex–attracted youths had higher frequency/quantity of tobacco use in their peer networks than did opposite-sex–attracted youths, and both-sex–attracted youths had higher frequency/quantity of alcohol use and misuse in their peer networks than opposite-sex–attracted youths. Among same- and both-sex–attracted youths, greater frequency/quantity of tobacco use in one’s social network predicted greater use of cigarettes. In addition, greater frequency/quantity of peers’ drinking and drinking to intoxication predicted more alcohol use and alcohol misuse in the both-sex–attracted group. These social network factors mediated sexual orientation–related disparities in tobacco use for both- and same-sex–attracted youths. Moreover, sexual orientation disparities in alcohol misuse were mediated by social network characteristics for the same-sex and both-sex–attracted youths. Importantly, sexual minority adolescents were no more likely to have other sexual minorities in their social networks than were sexual majority youths, ruling out an alternative explanation for our results. Conclusions: These findings highlight the importance of social networks as correlates of substance use behaviors among sexual minority youths and as potential pathways explaining sexual orientation disparities in substance use outcomes.

Based on a social dominance approach, aggression is conceptualized as a strategy used to gain position, power, and influence within the peer network. However, aggression may only be beneficial when targeted against particular peers; both victims' social standing and the number of victims targeted may impact aggressors' social standing. The current study examined associations between aggressors' targeting tendencies (victims' social standing and number of victims) and aggressors' own social standing, both concurrently and over time. Analyses were conducted using three analytic samples of seventh and eighth grade aggressors (Ns ranged from 161 to 383, 49% girls; 50% Latina/o). Participants nominated their friends; nominations were used to calculate social network prestige. Peer nominations were used to identify aggressors and their victim(s). For each aggressor, number of victims and victims' social network prestige were assessed. Aggressors with more victims and with highly prestigious victims had higher social network prestige themselves, and they increased more in prestige over time than aggressors with fewer victims and less prestigious victims (though there were some differences across analytic samples). Findings have implications for the need to extend the social dominance approach to better address the links between aggressors and victims. Aggr.

Alcohol peer influence of participating in organized school activities: a network approach.
Fujimoto, Kayo; Valente, Thomas W

This study compares the network influences on adolescent substance use from peers who coparticipated in school-sponsored organized activities (affiliation-based peer influence) with the influence both from their "nominated" friends (i.e., the adolescent named the alter as a friend), and only "reciprocated" friends (i.e., both adolescents mutually named each other as friends). The study also attempts to parse affiliation-based peer influence into the influence of both activity members who are also friends and those who are not, to address the potential confounding of these sources of peer influence. The study data consisted of a nationally representative sample of 12,551 adolescents in Grades 7-12 within 106 schools from the Add Health data. Ordinal logistic regression was conducted to estimate the effects of affiliation-based and friends influence on alcohol use and drinking frequency. Peer influence via organized activities (sports or clubs) with drinkers and the influence of friends who drink had significant effects on adolescent drinking. Peer influence through club activities with drinkers had a stronger effect on any drinking behavior than through sports activities with drinkers. After decomposing peer influence through activities by friendship status, influence through sport activities had a significant effect on drinking only when coparticipant drinkers were also reciprocated friends (but not nominated friends), whereas influence through club activities had a significant effect on drinking, regardless of friendship reciprocation. The design and implementation of school based substance use prevention and treatment programs should consider the contextual effects of school-sponsored activities.

Substance Use, Distress, and Adolescent School Networks
McLeod, Jane D.; Uemura, Ryotaro
2012-01-01
This study examined the associations of substance use, psychological distress, and mental health services receipt with the structure and content of adolescent school-based networks. Using data from the National Longitudinal Study of Adolescent Health, we found that substance use was associated with receiving more, but making fewer, peer nominations. It also was associated with less favorable network characteristics, such as low GPA. Services receipt was associated with receiving and making fewer nominations, less favorable network characteristics, and a lower likelihood of reciprocated best friendships. Psychological distress had fewer significant associations. All associations were modest in magnitude. Our results suggest the importance of considering multiple indicators of socioemotional problems and multiple dimensions of social networks in research on adolescent peer relations. PMID:23066337

Peer relationships improve for children with autism spectrum disorder (ASD) in clinic-based social skills groups but rarely generalize to real world contexts. This study compares child outcomes of two social skills interventions conducted in schools with children in Kindergarten through fifth grade. Children with ASD were randomized to one of two interventions that varied on group composition (mixed typical and ASD vs. all ASD or social difficulties) and intervention approach (didactic SKILLS based vs. activity-based ENGAGE groups). Interventions were implemented at school for 8 weeks (16 sessions) with an 8-week follow-up. Innovative measures of peer nomination and playground peer engagement, as well as teacher reports of child behavior problems and teacher-child relationship were analyzed for 137 children with ASD across four sites. On the primary outcome of social network connections from the peer nomination measure, there was no main effect of treatment, but there were moderator effects. Children with low teacher-child closeness or high conflict improved more in their social connections if they received the SKILLS intervention, whereas children with higher teacher-child closeness improved more if they received the ENGAGE intervention. Only two secondary outcome measures yielded significant effects of treatment. Children in the SKILLS groups increased peer engagement and decreased isolation during recess. Child behavior problems and teacher-child closeness moderated peer engagement such that children with higher behavior problems and lower closeness benefitted more from SKILLS groups. These findings suggest that social skills groups conducted at school can affect both peer engagement during recess as well as peer acceptability. Child characteristics and teacher-child relationship prior to intervention yield important information on who might benefit from a specific social skills intervention. © 2015 Association for Child and Adolescent Mental Health.

A Twin Study of Objective and Subjective Pubertal Timing and Peer Influence on Risk-Taking.
Kretsch, Natalie; Mendle, Jane; Harden, K Paige
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.

Peer Status Among Incarcerated Female Offenders: Associations With Social Behavior and Adjustment
Goldweber, Asha; Cauffman, Elizabeth; Cillessen, Antonius H. N.
2014-01-01
Peers are a powerful socializing force, especially during adolescence. Whether peer status holds the same meaning, correlates, and consequences for female offenders remains unknown. 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

Conceptually and methodologically distinct models exist for assessing quality of parent-child relationships, but few studies contrast competing models or assess their overlap in predicting developmental outcomes. Using observational methodology, the current study examined the distinctiveness of attachment theory-based and social learning theory-based measures of parenting in predicting two key measures of child adjustment: security of attachment narratives and social acceptance in peer nominations. A total of 113 5-6-year-old children from ethnically diverse families participated. Parent-child relationships were rated using standard paradigms. Measures derived from attachment theory included sensitive responding and mutuality; measures derived from social learning theory included positive attending, directives, and criticism. Child outcomes were independently-rated attachment narrative representations and peer nominations. Results indicated that Attachment theory-based and Social Learning theory-based measures were modestly correlated; nonetheless, parent-child mutuality predicted secure child attachment narratives independently of social learning theory-based measures; in contrast, criticism predicted peer-nominated fighting independently of attachment theory-based measures. In young children, there is some evidence that attachment theory-based measures may be particularly predictive of attachment narratives; however, no single model of measuring parent-child relationships is likely to best predict multiple developmental outcomes. Assessment in research and applied settings may benefit from integration of different theoretical and methodological paradigms.

The purpose of the study was to evaluate bidirectional associations between peer acceptance and both emotion and effortful control during kindergarten (N = 301). In both the fall and spring semesters, we obtained peer nominations of acceptance, measures of positive and negative emotion based on naturalistic observations in school (i.e., classroom, lunch/recess), and observers’ reports of effortful control (i.e., inhibitory control, attention focusing) and emotions (i.e., positive, negative). In structural equation panel models, peer acceptance in fall predicted higher effortful control in spring. Effortful control in fall did not predict peer acceptance in spring. Negative emotion predicted lower peer acceptance across time for girls but not for boys. Peer acceptance did not predict negative or positive emotion over time. In addition, we tested interactions between positive or negative emotion and effortful control predicting peer acceptance. Positive emotion predicted higher peer acceptance for children low in effortful control. PMID:28348445

Seventh-grade students (N = 324) completed social cognitive maps to identify peer groups and peer group leaders, sociometric nominations to describe their peers’ behaviors, and questionnaires to assess their own behaviors. Peer group members resembled one another in levels of direct and indirect aggression and substance use; girls’ cliques were more behaviorally homogenous than were boys’ cliques. On average, leaders (especially if they were boys) were perceived as engaging in more problem behaviors than were nonleaders. In girls’ cliques, peripheral group members were more similar to their group leader on indirect aggression than were girls who were more central to the clique. Peer leaders perceived themselves as being more able to influence peers but did not differ from nonleaders in their perceived susceptibility to peer influence. The findings contribute to our understanding of processes through which influence may occur in adolescent peer groups. PMID:19763241

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.

Despite the well established influence of peer experiences on adolescent attitudes, thoughts, and behaviors, surprisingly little research has examined the importance of peer context and the increased prevalence of depressive symptoms accompanying the transition into adolescence. Examination of social networks may provide some insight into the role of peers in the vulnerability of some adolescents to depression. To address this issue, we leveraged an existing sample of 5,563 Chinese 10th graders to incorporate social network data into a multilevel regression model of depressive symptoms. We found that, in this sample, being nominated as a friend was more important than being nominated as most liked. Social network centrality was significantly associated with depression; those adolescents who were less connected were more likely to suffer from depression. The risk of depression for those who were marginal members of classroom social networks was substantial. These findings suggest that a social network perspective could help to increase the effectiveness of programs aimed at preventing adolescent depression. PMID:23226988

The purpose of this study was to examine the interactive effects that a child's race and the racial composition of a classroom have on a variety of sociometric measures. Sociometric nominations were collected from 872 fifth-grade students (48% male, 48% Black) who were in classrooms that ranged from nearly all Black to nearly all White students. Hierarchical Linear Modeling analyses indicated that the race of the child, the race of the rater, and the classroom race composition each impacted sociometric nominations. Results suggest that schools that are more balanced in the distribution of Black and White students might promote more positive interracial peer relationships. However, opportunities to be highly liked and to be perceived as a leader might be greatest in a school in which the child is in the clear racial majority. © 2013 American Orthopsychiatric Association.
Teacher-Student Relationship and Peer Disliking and Liking across Grades 1–4

Between-child and within-child effects of teacher-student warmth and conflict on children’s peer-nominated disliking and liking across grades 1–4 (ages 6–10) were investigated in a sample of 746 ethnically diverse and academically at-risk children in Texas. Multi-level modeling controlled for time-invariant between-child differences while modeling the effect of time-varying TSR warmth and conflict on children’s peer relatedness. Teachers reported on warmth and conflict. Peers reported on liking and disliking. Above between-child effects of average levels of teacher warmth and conflict on initial level and rate of change in liking and disliking and classroom teacher support, year-to-year changes in TSR conflict and warmth predicted intra-individual change in children’s peer disliking but not peer liking.

This study aimed to understand how relationships with peers and teachers contribute to the development of internalizing problems via children’s social self-concept. The sample included 570 children aged 7 years 5 months (SD = 4.6 months). Peer nominations of peer rejection, child-reported social self-concept, and teacher-reported internalizing problems were assessed longitudinally in the fall and spring of Grades 2 and 3. Teacher reports of support to the child were assessed in Grade 2. Results showed that peer rejection impeded children’s social self-concept, which in turn affected the development of internalizing problems. Partial support was found for individual (but not classroom-level) teacher support to buffer the adverse effects of peer problems on children’s self-concept, thereby mitigating its indirect effects on internalizing problems.

Social network analysis was used to examine whether peer influence from one's social networks moderates obesity prevention program effects on obesity-related behaviors: healthful and unhealthful. Participants included 557 children residing in Southern California. The survey assessed health-promoting behaviors (i.e., physical activity at school, physical activity outside of school, and fruit and vegetable intake), as well as unhealthful behaviors (high-calorie, low-nutrient intake and sedentary activity), and peer exposure calculated from social network nominations as indicators of peer influence. Multilevel models were conducted separately on outcomes predicted by program participation, peer exposure, and program participation by peer exposure. Results indicated that peer exposure was positively associated with one's own healthful and unhealthful behaviors. Program participation effects were moderated by peer influence, but only when unhealthful peer influence was present. Results suggest that peer influence can diminish or amplify prevention programs Future interventions should consider peer-led components to promote healthful influence of peers on healthful and unhealthful behaviors, and programs should be mindful that their effects are moderated by social networks.

The Best Friendships of Shy/Withdrawn Children: Prevalence, Stability, and Relationship Quality
Rubin, Kenneth H.; Wojslawowicz, Julie C.; Rose-Krasnor, Linda; Booth-LaForce, Cathryn; Burgess, Kim B.
2013-01-01
The mutual best friendships of shy/withdrawn and control children were examined for prevalence, stability, best friend’s characteristics, and friendship quality. Using peer nominations of shy/socially withdrawn and aggressive behaviors, two groups of children were identified from a normative sample of fifth-grade children: shy/withdrawn (n = 169) and control (nonaggressive/nonwithdrawn; n = 163). Friendship nominations, teacher reports, and friendship quality data were gathered. Results revealed that shy/withdrawn children were as likely as control children to have mutual stable best friendships. Withdrawn children’s friends were more withdrawn and victimized than were the control children’s best friends; further, similarities in social withdrawal and peer victimization were revealed for withdrawn children and their friends. Withdrawn children and their friends reported lower friendship quality than did control children. Results highlight the importance of both quantitative and qualitative measures of friendship when considering relationships as risk and/or protective factors. PMID:16485175

Current research on trait EI in adolescents suggests that the construct impacts on several important domains of youths' psychological functioning, including school adjustment and achievement. The purpose of this study is to explore the role of trait EI and of its subcomponents, on adolescent's academic achievement. Data were collected from 321 Italian adolescents (162 female; Mage = 15.5, SD = 1.86; aged 13-18 years) recruited from secondary schools. The effects of perceived and actual peer nominations, gender, personality dimensions, and non-verbal cognitive abilities were also controlled. Results highlight that trait EI as assessed by means of the TEIQue impacts Italian but not math's grades, while trait EI's factors predicted both academic subjects, with significant contributions of Self-Control and Sociability. Limitations and implications are discussed. Copyright © 2017 The Foundation for Professionals in Services for Adolescents. Published by Elsevier Ltd. All rights reserved.

Previous studies have found mixed results on the relationship between empathy and peer acceptance. Emotional and cognitive components of empathy were hypothesised to play different roles in peer acceptance, and the relationship between empathy and peer acceptance differed across genders. In this study, 375 Chinese adolescents completed self-report measures of emotional and cognitive empathy. They also provided peer nominations that allowed for the determination of social preference and social impact scores. The results showed that a boy's cognitive empathy positively correlated with the extent to which he was liked by his male classmates, whereas a girl's cognitive empathy positively correlated with her social impact among her female classmates. This study suggests that empathy does not affect peer acceptance among adolescents uniformly; instead, gender plays a determinative role in the dialectics between social acceptance and empathy. © 2014 International Union of Psychological Science.

To test the hypotheses that medical students recognized by peers as the most positive social influencers would score (1) high on measures of engaging personality attributes that are conducive to relationship building (empathy, sociability, activity, self-esteem), and (2) low on disengaging personality attributes that are detrimental to interpersonal relationships (loneliness, neuroticism, aggression-hostility, impulsive sensation seeking). The study included 666 Jefferson Medical College students who graduated in 2011-2013. Students used a peer nomination instrument to identify classmates who had a positive influence on their professional and personal development. At matriculation, these students had completed a survey that included the Jefferson Scale of Empathy and Zuckerman-Kuhlman Personality Questionnaire short form and abridged versions of the Rosenberg Self-Esteem Scale and UCLA Loneliness Scale. In multivariate analyses of variance, the method of contrasted groups was used to compare the personality attributes of students nominated most frequently by their peers as positive influencers (top influencers [top 25% in their class distribution], n = 176) with those of students nominated least frequently (bottom influencers [bottom 25%], n = 171). The top influencers scored significantly higher on empathy, sociability, and activity and significantly lower on loneliness compared with the bottom influencers. However, the effect size estimates of the differences were moderate at best. The research hypotheses were partially confirmed. Positive social influencers appear to possess personality attributes conducive to relationship building, which is an important feature of effective leadership. The findings have implications for identifying and training potential leaders in medicine.
Sociodynamic relationships between children who stutter and their non-stuttering classmates
Davis, Stephen; Howell, Peter; Cooke, Frances
2007-01-01
Background: Previous research has indicated that children who stutter are more likely to be bullied and to hold a lower social position than their peers who do not stutter. However, the majority of this research has used data from respondents who were in the educational system more than 20 years ago. The current policy on integration of children with severe disabilities into mainstream education and the increased awareness of bullying in schools would indicate that attitudes toward children who stutter might have changed in the intervening period. Method: The study uses a sociometric scale (adapted from Coie, Dodge, & Coppotelli, 1982) to assess children who stutter in classroom groups with fluent peers. The peer relationships between 16 children who stutter and their classmates (403 children in total) were examined. Results: Children who stutter were rejected significantly more often than were their peers and were significantly less likely to be popular. When compared to children who do not stutter, the children who stutter were less likely to be nominated as ‘leaders’ and were more likely to be nominated to the ‘bullied’ and ‘seeks help’ categories. Conclusions: The changes in integration policy and the implementation of anti-bullying policies in many schools appear to have made little impact on the social status of children who stutter. The incidence of bullying and rejection reported in this study has implications for schools and clinicians. PMID:12405481
Bullies, Victims, and Antipathy: The Feeling is Mutual
Hafen, Christopher A.; Laursen, Brett; Nurmi, Jari-Eri; Salmela-Aro, Katariina
2013-01-01
In this study we consider whether bullies and victims are disliked by most of their classmates, or whether antipathy is concentrated among the occupants of these roles. Antipathy nominations were collected from a community sample of 699 Finnish adolescents (14 to 17 years of age), who described their own bullying and victimization, as well as problem behaviors and school engagement. Victimization was associated with antipathy, but the strength of the association differed according to characteristics of the nominator. Victimization was related to antipathy when the nominator was high on bullying but not low. Similarly, bullying was related to antipathy when the nominator was high on victimization, but not low. The findings indicate that although bullies and victims have elevated mean levels of rejection, they are not disliked by most peers but rather by those who report themselves to be high on these attributes.

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
Peer status and aggression as predictors of dating popularity in adolescence.
Houser, John J; Mayeux, Lara; Cross, Cassandra
2015-03-01
Research has identified links between dating and aversive behavior such as aggression and bullying in adolescence, highlighting the need for studies that further our understanding of romantic relationships and their dynamics during this period. This study tested the associations between dating popularity and overt and relational aggression, social preference, and peer popularity. Of particular interest were the moderating roles of social preference and peer popularity in the association of aggression with dating popularity. Further moderation by gender was also explored. Participants were 478 ninth-graders (48% girls) with peer nomination scores for peer status, aggression, and dating popularity. Dating popularity was positively correlated with popularity, social preference, and overt and relational aggression. Regression models indicated that popular, overtly aggressive girls were seen as desirable dating partners by their male peers. Relational aggression was associated with dating popularity for both boys and girls, especially for youths who were well-liked by peers. These findings are interpreted in light of developmental-contextual perspectives on adolescent romantic relationships and Resource Control Theory.

IBA inventory measurement errors at the 95% confidence levelmore » were calculated using the correlation of IBA gas temperature rise, or (hydride) bed temperature rise above ambient temperature, versus simulated tritium inventory.Prototype bed IBA inventory errors at 100 SLPM were the largest for gas flows through the vacuum jacket: 15.2 grams for the bed temperature rise and 11.5 grams for the gas temperature rise. For a 100 SLPM U-tube flow, the inventory error was 2.5 grams using bed temperature rise and 1.6 grams using gas temperature rise. For 50 to 100 SLPM U-tube flows, the IBA gas temperature rise inventory errors were nominally one to two grams that increased above four grams for flows less than 50 SLPM. For 50 to 100 SLPM U-tube flows, the IBA bed temperature rise inventory errors were greater than the gas temperature rise errors, but similar errors were found for both methods at gas flows of 20, 30, and 40 SLPM.Electric heater IBA tests were done for six production hydride beds using a 45 SLPM U-tube gas flow. Of the duplicate runs performed on these beds, five of the six beds produced IBA inventory errors of approximately three grams: consistent with results obtained in the laboratory prototype tests.« less

Research consistently links adolescents' and young adults' drinking with their peers' alcohol intake. In interpreting this correlation, 2 essential questions are often overlooked. First, which peers are more important, best friends or broader social networks? Second, do peers cause increased drinking, or do young people select friends whose drinking habits match their own? The present study combines social network analyses with family (twin and sibling) designs to answer these questions via data from the National Longitudinal Study of Adolescent Health. Analysis of peer nomination data from 134 schools (n = 82,629) and 1,846 twin and sibling pairs shows that peer network substance use predicts changes in drinking from adolescence into young adult life even after controlling for genetic and shared environmental selection, as well as best friend substance use. This effect was particularly strong for high-intensity friendships. Although the peer-adolescent drinking correlation is partially explained by selection, the present finding offers powerful evidence that peers also cause increased drinking. PMID:22390657
Social network effects in contraceptive behavior among adolescents.
Ali, Mir M; Amialchuk, Aliaksandr; Dwyer, Debra S
2011-10-01
To quantify empirically the role of peer social networks in contraceptive behavior among adolescents. Using longitudinal data from a nationally representative sample of adolescents, the authors use a multivariate structural model with school-level fixed effects to account for the problems of contextual effects, correlated effects, and peer selection to reduce the potential impact of biases from the estimates of peer influence. The peer group measures are drawn not only from the nominations of close friends but also from classmates. Contraception use among the peer groups was constructed using the peers' own reports of their contraceptive behavior. Controlling for parental characteristics and other demographic variables, the authors find that a 10% increase in the proportion of classmates who use contraception increases the likelihood of individual contraception use by approximately 5%. They also find evidence that the influence of close friends diminishes after accounting for unobserved environmental confounders. The findings of this study support the findings in the literature that peer effects are important determinants of contraception use even after controlling for potential biases in the data. Effective policy aimed at increasing contraception use among adolescents should consider these peer effects.

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
Perceptions of intimacy and friendship reciprocity moderate peer influence on aggression.
Meter, Diana J; Casper, Deborah M; Card, Noel A
2015-01-01
Previous research has shown that close friends' influence can exacerbate adolescents' aggressive behavior, but results of studies which examine whether friendships of greater or lesser qualities moderate peer influence effects are inconsistent. The present study tested whether the perception of the positive friendship quality of intimate exchange and friendship reciprocity moderated best friend influence on participant aggression over time. The 243 participants were approximately 12 years old and ethnically diverse. Neither intimate exchange nor reciprocity significantly moderated friend influence on aggression in a simple way, but the interaction of intimate exchange and friendship reciprocity predicted peer influence on participants' aggression over time. Specifically, highly intimate, nonreciprocal best friendships and less intimate, reciprocal best friendships showed greatest influence when friends' proportion of peer nominations for aggression was high. Reciprocity and intimacy should be considered when predicting peer influence on aggression. © 2014 Wiley Periodicals, Inc.

Descriptive norms are commonly associated with participant drinking. However, study participants may incorrectly perceive that their peers drink about the same amount as they do, which would bias estimates of drinking homogeneity. This research examined the magnitude of associations between emerging adults' reports of their own drinking and peer drinking measured the previous year by measures of (1) participants' perceptions of friends' drinking; and (2) actual drinking reported by nominated peers. The data are from annual surveys conducted in 2014 and 2015, Waves 4 and 5 (the first 2 years after high school) of 7 annual assessments as part of the NEXT Generation Health Study (n = 323). Associations of participant alcohol use with perceived friend use (five closest, closest male, and closest female friends), and with actual peer use. Logistic regression analyses estimated the magnitudes of prospective associations between each measure of peer drinking at W4 and participant drinking at W5.

Documented associations between academic and social functioning have been inconsistent. These discrepancies may reflect the moderating role of sociocultural context. In this study, we examined ethnicity and gender as moderators of this relation. We collected peer nominations, GPA from school records, and self-report questionnaires for 519 Vietnamese-American and Mexican-American middle school students (mean age = 12.7 years). Using general linear modeling, we found that academic and social functioning were more strongly and positively linked for Vietnamese-Americans relative to Mexican-Americans, and for girls relative to boys. We also examined group differences in achievement values, and found that Vietnamese-Americans were more likely to admire and be friends with high-achieving peers. The results suggest that peers provide one context in which ethnic and gender differences in achievement values emerge, and interventions aimed at reducing the achievement gap may benefit from incorporating a focus on peers.

Peer effects in adolescent BMI: evidence from Spain.
Mora, Toni; Gil, Joan
2013-05-01
This paper extends the recent literature on the influence of peers on adolescent weight on three new fronts. First, based on a survey of secondary school students in Spain in which peers are formed by nominated classmate friends, we find a more powerful positive and significant causal effect of friends' mean BMI on adolescent BMI than previous US-based research. These results are in line with international data, which show that peer group contact tends to vary across countries. Our findings cover a large set of controls, fixed effects, the testing of correlated unobservables, contextual influences and instrumental variables. Second, social interactions are identified through the property of intransitivity in network relationships. Finally, we report evidence of a strong, positive effect of peer pressure on several subgroups of adolescents in an attempt to study their vulnerability to social influences.

The present study investigated whether the members of adolescents' peer groups are similar in reading and spelling disabilities and whether this similarity contributes to subsequent school achievement and educational attainment. The sample consisted of 375 Finnish adolescents whose reading and spelling disabilities were assessed at age 16 with the Finnish dyslexia screening test. The students also completed a sociometric nomination measure that was used to identify their peer groups. Register information on participants' school grades also was available, and educational attainment in secondary education was recorded 5 years after completion of the 9 years of basic education. The results revealed that the members of adolescent peer groups resembled each other in reading disabilities but not in those of spelling. Reading disabilities and academic achievement shared within the peer group also contributed to educational attainment in secondary education. Finally, reading disabilities played a larger role in educational attainment among males than among females.
The role of peer group aggression in predicting adolescent dating violence and relationship quality.
Ellis, Wendy E; Chung-Hall, Janet; Dumas, Tara M

Past research has shown that adolescent peer groups make a significant contribution to shaping behavior but less is known about the role of peer groups in adolescent dating relationships. This longitudinal study examined the contribution of aggressive peer group norms on relationship quality and dating violence among dating adolescents. At the beginning of the school year (T1) and 6 months later (T2), participants (n = 1,070; M(age) = 15.45; 49 % Female) provided self-reports of attitudes towards aggression, and physically- and relationally-aggressive behaviors. Peer groups were identified using a peer-nomination technique and aggressive behaviors and attitudes were averaged across peer groups. Participants with dating experience (n = 598) reported on the frequency of their experience with dating violence (both as a victim and perpetrator). Multilevel analyses indicated that peer group relational aggression at T1 positively predicted dating abuse victimization and perpetration, and negatively predicted relationship quality at T2, beyond individual predictions. An unexpected finding was that membership in physically aggressive peer groups at T1 was associated positively with relationship quality at T2. Results point to the importance of the peer group in shaping adolescent dating experiences.

The negative effects of prejudice on interpersonal relationships within adolescent peer groups.
Poteat, V Paul; Mereish, Ethan H; Birkett, Michelle
2015-04-01
Social development theories highlight the centrality of peer groups during adolescence and their role in socializing attitudes and behaviors. In this longitudinal study, we tested the effects of group-level prejudice on ensuing positive and negative interpersonal interactions among peers over a 7-month period. We used social network analysis to identify peer groups based on sociometric nominations, followed by multilevel modeling of the effects of sexual prejudice at the group level on interpersonal interactions among individuals in these groups. As hypothesized, the interpersonal interactions in peer groups with stronger group-level sexual prejudice were distinct from and poorer than those in groups with weaker group-level sexual prejudice. Moreover, longitudinal models indicated that adolescents in groups with stronger initial sexual prejudice reported worse interpersonal interactions with their peers seven months later. These findings provide a contextual understanding of prejudice and its negative effects on how adolescents come to relate with one another over time. (c) 2015 APA, all rights reserved).

Little is known about attributes that elicit romantic desirability in early adolescence. The current study, with a sample of 531 sixth-grade students (45% boys) attending ethnically diverse middle schools, used a resource control framework to explore which self-reported behaviors (e.g., empathy and aggression) and peer-reported status (e.g., acceptance and perceived popularity) predict the likelihood of being considered romantically desirable (i.e., receiving at least one "crush" nomination from an opposite sex grademate). Self-reported empathy was positively associated with students' romantic desirability (primarily for those with high peer acceptance), whereas self-reported aggression on its own did not. Both peer-acceptance and popularity also were positively associated with students' romantic desirability, and aggressive behavior reduced popularity's effect. Although aggression may be integral for obtaining high peer status across cultures, prosocial behaviors were romantically valued. Our findings suggest that peer-vetted social status elicits romantic interest and during early adolescence, nice guys and gals really do not finish last.

The aim of the present study is to analyze the relation between authoritative and permissive parenting styles with the kinds of adolescent peer relationships (attachment, victimization, or aggression), and of the latter ones, in turn, with academic self-efficacy, and academic performance, in three waves that range from the early-mid adolescence to late adolescence. Five hundred Spanish adolescents, of both sexes, participated in a three-wave longitudinal study in Valencia, Spain. In the first wave, adolescents were either in the third year of secondary school or the fourth year of secondary school. The mean age in the first wave was 14.70 (SD = 0.68; range = 13–16 years). Child Report of Parental Behavior Inventory (Schaefer, 1965; Samper et al., 2006), Peer Attachment (from the Inventory of Parent and Peer Attachment by Armsden and Greenberg, 1987), Victimization (from the Kit at School, Buhs et al., 2010), Physical and Verbal Aggression Scale (Caprara and Pastorelli, 1993; Del Barrio et al., 2001), items of academic self-efficacy, and items of academic performance were administered. Structural equations modeling—path analysis was employed to explore the proposed models. The results indicated that parenting styles relate to the way the adolescents develops attachments to their peers and to academic self-efficacy. The mother's permissive style is an important positive predictor of aggressive behavior and a negative predictor of attachment to their peers. At the end, peer relations and academic self-efficacy are mediator variables between parenting styles and academic performance. PMID:29326615

The special phenomenon, nominated as bed inventory overturn, in circulating fluid bed (CFB) riser with pant-leg structure was studied with model calculation and experimental work. A compounded pressure drop mathematic model was developed and validated with the experimental data in a cold experimental test rig. The model calculation results agree well with the measured data. In addition, the intensity of bed inventory overturn is directly proportional to the fluidizing velocity and is inversely proportional to the branch point height. The results in the present study provide significant information for the design and operation of a CFB boiler with pant-leg structure.more » 15 refs., 10 figs., 1 tab.« less

The authors examined the associations between mixed-grade rejection (rejection by peers in a different school grade), anxious-withdrawal, aggression, and psychological adjustment in a middle school setting. Participants were 181 seventh-grade and 180 eighth-grade students (M age = 13.20 years, SD = 0.68 years) who completed peer nomination and self-report measures in their classes. Analyses indicated that in general, same- and mixed-grade rejection were related to overt and relational aggression, but neither type was related to anxious-withdrawal. Mixed-grade rejection was associated uniquely and negatively with self-esteem for seventh-grade boys, while increasing the loneliness associated with anxious-withdrawal. The results suggest that school-wide models of peer relations may be promising for understanding the ways in which different peer contexts contribute to adjustment in middle school settings.

The nature of excellent clinicians at an academic health science center: a qualitative study.

To understand the nature of excellent clinicians at an academic health science center by exploring how and why excellent clinicians achieve high performance. From 2008 to 2010, the authors conducted a qualitative study using a grounded theory approach. Members of the Clinical Advisory Committee in the Department of Pediatrics at the University of Toronto nominated peers whom they saw as excellent clinicians. The authors then conducted in-depth interviews with the most frequently nominated clinicians. They audio-recorded and transcribed the interviews and coded the transcripts to identify emergent themes. From interviews with 13 peer-nominated, excellent clinicians, a model emerged. Dominant themes fell into three categories: (1) core philosophy, (2) deliberate activities, and (3) everyday practice. Excellent clinicians are driven by a core philosophy defined by high intrinsic motivation and passion for patient care and humility. They refine their clinical skills through two deliberate activities-reflective clinical practice and scholarship. Their high performance in everyday practice is characterized by clinical skills and cognitive ability, people skills, engagement, and adaptability. A rich theory emerged explaining how excellent clinicians, driven by a core philosophy and engaged in deliberate activities, achieve high performance in everyday practice. This theory of the nature of excellent clinicians provides a holistic perspective of individual performance, informs medical education, supports faculty career development, and promotes clinical excellence in the culture of academic medicine.

The most important articles on infectious diseases (ID) pharmacotherapy published in the peer-reviewed literature in 2014, as nominated and selected by panels of pharmacists and others with ID expertise, are summarized. Members of the Houston Infectious Diseases Network were asked to nominate articles published in 2014 from prominent peer-reviewed journals that were felt to have a major impact in the field of ID pharmacotherapy. A list of 19 nominated articles on general ID-related topics and 9 articles specifically related to human immunodeficiency virus (HIV) infection or acquired immunodeficiency syndrome (AIDS) was compiled. In a national online survey, members of the Society of Infectious Diseases Pharmacists (SIDP) were asked to select from the list 10 general ID articles believed to have made a significant contribution to the field of ID pharmacotherapy and 1 article contributing to HIV/AIDS pharmacotherapy. Of the 291 SIDP members surveyed, 134 (46%) and 56 (19%) participated in the selection of general ID-related articles and HIV/AIDS-related articles, respectively. The 11 highest-ranked papers (10 general ID-related articles, 1 HIV/AIDS-related article) are summarized here. With the vast number of articles published each year, it is difficult to remain up-to-date on current, significant ID pharmacotherapy publications. This review of significant publications in 2014 may be helpful by lessening this burden. Copyright © 2015 by the American Society of Health-System Pharmacists, Inc. All rights reserved.
Social network effects in alcohol consumption among adolescents.
Ali, Mir M; Dwyer, Debra S
2010-04-01
In this paper we seek to empirically quantify the role of peer social networks in explaining drinking behavior among adolescents. Using data from a nationally representative sample of adolescents we utilize a multivariate structural model with school-level fixed effects to account for the problems of contextual effects, correlated effects and peer selection to purge the potential biases from the estimates of peer influence. Our peer group measures are drawn not only from the nomination of close friends, but also from classmates. Drinking behavior among the peer groups was constructed using the peers' own report of their alcohol consumption. Controlling for parent level characteristics, and other demographic parameters, we find that a 10% increase in the proportion of classmates who drink will increase the likelihood of drinking participation and frequency by approximately four percentage points. We also find evidence to show that the influence of close friends, while still significant, diminishes in magnitude after accounting for unobserved environmental confounders. Our findings support the literature that peer effects are important determinants of drinking behavior even after controlling for potential biases. Effective policy aimed at reducing alcohol consumption among adolescents would consider these significant peer effects. 2009 Elsevier Ltd. All rights reserved.

Peer assessment of personality traits and pathology in female college students.
Oltmanns, T F; Turkheimer, E; Strauss, M E
1998-03-01
Assessment procedures for personality disorders (PDs) typically rely on self-reports, even though some people with PDs may be unable to view themselves realistically or are unwilling to report socially undesirable traits. Close associates may provide important information regarding the presence of PD traits. Peer nomination is a reliable and valid assessment procedure that can be adapted to the study of PDs for research purposes. This study focused on characteristic features that define narcissistic, dependent, and obsessive-compulsive PDs using information collected from both self and others in a nonclinical sample of women. It was designed to identify specific areas of agreement and discrepancy between self-report and peer assessment in the measurement of characteristic features of these disorders.
Cell Phone Use While Driving: Prospective Association with Emerging Adult Use.
Trivedi, Neha; Haynie, Denise; Bible, Joe; Liu, Danping; Simons-Morton, Bruce
2017-09-01
Secondary task engagement such as cell phone use while driving is a common behavior among adolescents and emerging adults. Texting and other distracting cell phone use in this population contributes to the high rate of fatal car crashes. Peer engagement in similar risky driving behaviors, such as texting, could socially influence driver phone use behavior. The present study investigates the prospective association between peer and emerging adult texting while driving the first year after high school. Surveys were conducted with a national sample of emerging adults and their nominated peers. Binomial logistic regression analyses, adjusting for gender, race/ethnicity, parental education, and family affluence, showed that participants (n=212) with peers (n=675) who reported frequently texting while driving, were significantly more likely to text while driving the following year (odds ratio, 3.01; 95% CI, 1.19-7.59; P=0.05). The findings are consistent with the idea that peer texting behavior influences the prevalence of texting while driving among emerging adults. Copyright © 2017 Elsevier Ltd. All rights reserved.

Recent research has revealed significant heterogeneity in the peer difficulties associated with social withdrawal subtypes during early adolescence, but little is known about possible sources of that heterogeneity. This study of 194 Indian young adolescents (48% female; 90% Hindu; M age= 13.35 years) evaluated whether the peer adversity related to self-reported social withdrawal subtypes (shyness, unsociability, avoidance) varied as a function of peer-nominated overt and relational aggression, and gender. Regression analyses revealed that overt aggression and gender moderated the pathways between shyness and peer exclusion and peer victimization such that the associations were significant and positive only for boys who were high and girls who were low in overt aggression. Several additional moderator effects were found, including results revealing that relational aggression (in certain cases, in conjunction with gender) moderated the association between: (1) avoidance and peer exclusion and peer rejection, (2) shyness and peer rejection, and (3) unsociability and peer victimization. For adolescents who were average and low in relational aggression, avoidance was positively related to peer rejection, and unsociability was positively related to peer victimization. However, only for boys who were high in relational aggression, avoidance was found to be positively related to peer exclusion, and shyness was positively related to peer rejection. The findings highlight the importance of considering additional individual risk factors in studies of social withdrawal subtypes and point to important differences for young adolescent withdrawn boys and girls.
Seeing Eye to Eye: Predicting Teacher-Student Agreement on Classroom Social Networks
Neal, Jennifer Watling; Cappella, Elise; Wagner, Caroline; Atkins, Marc S.
2010-01-01
This study examines the association between classroom characteristics and teacher-student agreement in perceptions of students’ classroom peer networks. Social network, peer nomination, and observational data were collected from a sample of second through fourth grade teachers (N=33) and students (N=669) in 33 classrooms across five high poverty urban schools. Results demonstrate that variation in teacher-student agreement on the structure of students’ peer networks can be explained, in part, by developmental factors and classroom characteristics. Developmental increases in network density partially mediated the positive relationship between grade level and teacher-student agreement. Larger class sizes and higher levels of normative aggressive behavior resulted in lower levels of teacher-student agreement. Teachers’ levels of classroom organization had mixed influences, with behavior management negatively predicting agreement, and productivity positively predicting agreement. These results underscore the importance of the classroom context in shaping teacher and student perceptions of peer networks. PMID:21666768

Longitudinal social network analysis (SNA) was used to examine how a social-emotional learning (SEL) intervention may be associated with peer socialization on academic performance. Fifth graders (N = 631; 48 % girls; 9 to 12 years) were recruited from six elementary schools. Intervention classrooms (14) received a relationship building intervention (RBI) and control classrooms (8) received elementary school as usual. At pre- and post-test, students nominated their friends, and teachers completed assessments of students' writing and math performance. The results of longitudinal SNA suggested that the RBI was associated with friend selection and peer influence within the classroom peer network. Friendship choices were significantly more diverse (i.e., less evidence of social segregation as a function of ethnicity and academic ability) in intervention compared to control classrooms, and peer influence on improved writing and math performance was observed in RBI but not control classrooms. The current findings provide initial evidence that SEL interventions may change social processes in a classroom peer network and may break down barriers of social segregation and improve academic performance.
School engagement trajectories in adolescence: The role of peer likeability and popularity.
Engels, Maaike C; Colpin, Hilde; Van Leeuwen, Karla; Bijttebier, Patricia; Den Noortgate, Wim Van; Claes, Stephan; Goossens, Luc; Verschueren, Karine
2017-10-01
This accelerated longitudinal study examined how peer status (i.e., peer likeability and popularity) is involved in adolescents' school engagement trajectories. A large sample of students was followed from Grades 7 to 11 (N=1116; M age =13.79years). Students' school engagement and peer status were assessed using self-reports and peer nominations, respectively. Latent growth curve modeling revealed that different engagement dimensions were differentially associated with peer status. Likeability was positively related to both behavioral and emotional engagement in Grade 7, but not to behavioral and emotional disaffection. In contrast, popularity was related to less behavioral engagement and more behavioral disaffection at the start of secondary education, but not to emotional engagement and disaffection. Moreover, students' aggressive behavior moderated the relation between popularity and behavioral engagement in Grade 7, denoting the risk of popularity in combination with average and high levels of aggression. Results suggest that adolescents' popularity may interfere with meeting academic demands in general and with showing engagement in particular.

Inattentiveness, parental smoking and adolescent smoking initiation.
Barman, Satu K; Pulkkinen, Lea; Kaprio, Jaakko; Rose, Richard J
2004-08-01
To examine how adolescents' inattentive behaviour, together with parental smoking patterns, predicts smoking initiation by age 14. DESIGN, SETTINGS: A prospective, longitudinal study: baseline at ages 11-12, follow-up at age 14. A population-based sample of Finnish twins, born 1983-1987, with parents and classroom teachers as additional informants. Two groups were formed, allocating the co-twins of each family into separate groups: the study sample and a replication sample. Twin individuals (n = 4552), aged 11-12 at baseline and 14 (average 14.04 years) at follow-up. At baseline, inattentiveness was assessed with the Multidimensional Peer Nomination Inventory (MPNI, Teacher Form) and parental smoking with individual questionnaires completed by each twins' parents; at the age 14 follow-up, adolescent smoking was assessed with a self-report questionnaire. At age 14, 57% reported never having smoked, 34% had experimented with cigarettes and 9% were current smokers. Inattentiveness and parental smoking additively predicted both experimental and current smoking in adolescence. The effects were independent of each other. The risk related to inattentiveness itself is high, but in combination with the effects of parental smoking, the probability of current smoking can rise as high as 38%, compared with 5% without these two risk factors. For prevention purposes, parental commitment to non-smoking should be emphasized.

Risky sexual behavior poses significant health risks by increasing sexually transmitted infections and unintended pregnancies. Previous research has documented many factors related to risky sexual behavior. This study adds to the literature by proposing a prospective, developmental model of peer factors related to risky sexual behavior. Developmental pathways to risky sexual behavior were examined in a sample of 517 individuals (51% female; 82% European American, 16% African American, 2% other) followed from age 5 to 27. Structural equation models examined direct and indirect effects of peer rejection (assessed via peer nominations at ages 5, 6, 7, and 8), affiliation with deviant peers (assessed via self-report at ages 11 and 12), and delinquency (assessed via maternal report at ages 10 and 16) on risky sexual behavior (assessed via self-report at age 27). More peer rejection during childhood, affiliation with deviant peers during pre- adolescence, and delinquency in childhood and adolescence predicted more risky sexual behavior through age 27, although delinquency at age 16 was the only risk factor that had a significant direct effect on risky sexual behavior through age 27 above and beyond the other risk factors. Peer rejection was related to subsequent risk factors for girls but not boys. Peer risk factors as early as age 5 shape developmental pathways through childhood and adolescence and have implications for risky sexual behavior into adulthood. PMID:25150986

Associations of peer victimization with adolescent depression and social phobia (SP), while controlling for comorbidity between them, have not been sufficiently explored in earlier research. A total of 3156 Finnish adolescents aged 15-16 years participated in a survey study. Self-reported peer victimization, as well as self-reported depression (Beck Depression Inventory), SP (Social Phobia Inventory), and selected background variables were assessed. Frequency of overt and covert peer victimization was examined among four groups: (1) adolescents with depression non-comorbid with SP (DEP), (2) those with SP non-comorbid with depression (SP), (3) those with both SP and depression (SP+DEP), and (4) controls, with neither. A logistic regression analysis controlling for confounding familial (family moving, parental unemployment), and psychopathology (delinquency, aggressiveness, general anxiety) covariates was conducted to confirm the associations between peer victimization and the four groups. Among boys the comorbid SP+DEP group reported the highest rates of both overt and covert victimization, these being significantly higher than among both DEP and SP groups. Among girls covert victimization was again most frequent in the SP+DEP group, but overt victimization was not more frequent in the comorbid group than it was in the DEP and SP groups. In the logistic regression analysis depression without SP did not maintain an independent association with either type of victimization. Instead, SP without depression with ORs from 2.8 to 4.3, and SP comorbid with depression, with ORs between 3.2 and 11.4 had independent associations with peer victimization. In conclusion, overt and covert peer victimization seem to be associated with SP, rather than depression, among adolescents.

One of the more controversial issues related to maternal employment in the United States concerns the timing of entry into the workforce and its effect on children, particularly during the first year of the child's life. Some studies show deleterious effects on children, such as increases in aggression and noncompliance, while others document few negative and even positive effects of early employment. This study examined the long-term effects of maternal employment during the child's first year of life on the social behavior of 171 third- and fourth-grade children in two-parent families. The moderating effects of child gender and social class were investigated. The extent to which stability in alternative care arrangements statistically explained links between early maternal employment and child outcomes was tested. After controlling for child gender, and maternal ethnicity, social class, and current employment status, third- and fourth-grade children whose mothers were employed during their first year of life evinced more acting out and less frustration tolerance and were nominated more often by peers for 'hitting' and 'being mean' than children whose mothers were not employed. There was some evidence that these associations were moderated by child gender and social class: boys, but not girls, whose mothers were employed during the first year were subsequently rated by teachers as acting out more than other children, and were also more likely to be nominated by peers for hitting. Higher nominations for hitting were only found in the working class. Finally, there was partial evidence that the number of alternative child-care arrangements during the first year accounted for the links between early maternal employment and subsequent child outcomes. These results are congruent with extant research that posits a risk of early employment on socioemotional development, but show that this risk is partially attributable to child-care instability.
Loneliness in Early Adolescence: Friendship Quantity, Friendship Quality, and Dyadic Processes.
Lodder, Gerine M A; Scholte, Ron H J; Goossens, Luc; Verhagen, Maaike
2017-01-01
Friendship quantity and quality are related to adolescent loneliness, but the exact link between these constructs is not well understood. The present study aimed to examine whether adolescents' perception of friendship quantity and quality, and the perceptions of their peers, were related to loneliness. We examined the relation between loneliness and the number of unilateral and reciprocal friendships and compared the views of best friendship quality. Overall, 1,172 Dutch adolescents (49.1% male, M age = 12.81, SD = .43) nominated their friends and rated their friendship quality. Friendship quantity was measured using sociometrics to distinguish reciprocated and unilateral (i.e., one-sided) friendships. The analyses indicated that loneliness was related to fewer reciprocal and unilateral-received friendships (i.e., the adolescent received a friendship nomination but did not reciprocate that nomination) and a lower quality of best friendship. Actor-partner interdependence analyses revealed that adolescents' loneliness was related to a less positive evaluation of their friendship, as reported by adolescents themselves (i.e., a significant actor effect) but not by their friends (i.e., nonsignificant partner effect). These findings (a) indicate that loneliness is negatively related to the number of friends adolescents have, as perceived by themselves and their peers and (b) suggest that, once a friendship is established, lonely adolescents may interpret the friendship quality less positively compared to their friends. Implications of these findings for our current understanding of adolescent loneliness are discussed, and suggestions for future research are outlined.

Most peer influence research examines socialization between adolescents and their best friends. Yet, adolescents also are influenced by popular peers, perhaps due to misperceptions of social norms. This research examined the extent to which out-group and in-group adolescents misperceive the frequencies of peers' deviant, health risk, and adaptive behaviors in different reputation-based peer crowds (Study 1) and the prospective associations between perceptions of high status peers' and adolescents' own substance use over 2.5 years (Study 2). Study 1 examined 235 adolescents' reported deviant (vandalism, theft), health risk (substance use, sexual risk), and adaptive (exercise, studying) behavior, and their perceptions of Jocks', Populars', Burnouts', and Brains' engagement in the same behaviors. Peer nominations identified adolescents in each peer crowd. Jocks and Populars were rated as higher status than Brains and Burnouts. Results indicated that peer crowd stereotypes are caricatures. Misperceptions of high status crowds were dramatic, but for many behaviors, no differences between Populars'/Jocks' and others' actual reported behaviors were revealed. Study 2 assessed 166 adolescents' substance use and their perceptions of popular peers' (i.e., peers high in peer perceived popularity) substance use. Parallel process latent growth analyses revealed that higher perceptions of popular peers' substance use in Grade 9 (intercept) significantly predicted steeper increases in adolescents' own substance use from Grade 9 to 11 (slope). Results from both studies, utilizing different methods, offer evidence to suggest that adolescents misperceive high status peers' risk behaviors, and these misperceptions may predict adolescents' own risk behavior engagement.

This study explored the longitudinal relations among peer victimization, depression, and academic achievement in Chinese primary school students. Participants were N = 945 fourth-grade students (485 boys, 460 girls; M age = 10.16 years, SD = 2 months) attending elementary schools in Shanghai, People's Republic of China. Three waves of data on peer victimization, depression, and academic achievement were collected from peer nominations, self-reports, and school records, respectively. The results indicated that peer victimization had both direct and indirect effects on later depression and academic achievement. Depression also had both direct and indirect negative effects on later academic achievement, but demonstrated only an indirect effect on later peer victimization. Finally, academic achievement had both direct and indirect negative effects on later peer victimization and depression. The findings show that there are cross-cultural similarities and differences in the various transactions that exist among peer victimization, depression, and academic achievement.

Young people's social standing among friends and peers has been linked to general levels of drinking and has been shown to influence others' drinking. We extend previous research by examining young adults' status within their natural-occurring drinking groups as a predictor of their subsequent alcohol consumption and encouragement of group members' alcohol consumption during a night out at licensed drinking establishments, a salient context for heavy drinking and alcohol-related risk among young adults. We recruited same-sex young adult drinking groups (n = 104 groups; 63 all-male; average group size = 3.4 members; Mage = 21.86) on their way to drinking establishments to complete a survey-containing measures of member-nominated within-group status, likeability, and self-reported alcohol consumption-and a breathalyzer test. At the end of the evening, participants completed the same alcohol consumption measures and were asked to nominate group members who encouraged other members to drink that night. Multilevel analysis revealed that higher-status members engaged in the most alcohol consumption (via both self-report and breathalyzer) but in heavier drinking groups only. Higher-status members also encouraged the most alcohol consumed by others, regardless of levels of group drinking. Further, even though being liked by one's peers was positively related to intoxication that night, it did not account for the significant relationship between within-group status and drinking. Results suggest that peer-related prevention programs for young adults' problem drinking may benefit from focusing on the structure and dynamic of young people's drinking groups. Also, programs targeting peer norms may be more successful if they incorporate status-related issues. Copyright © 2013 by the Research Society on Alcoholism.

The purpose of this study was to examine the educational impact of an intervention, the inquiry-focused textbook Integrating Concepts in Biology (ICB), when used in a yearlong introductory biology course sequence. Student learning was evaluated using three published instruments: 1) The Biology Concept Inventory probed depth of student mastery of fundamental concepts in organismal and cellular topics when confronting misconceptions as distractors. ICB students had higher gains in all six topic categories (+43% vs. peers overall, p < 0.01). 2) The Biology Card Sorting Task assessed whether students organized biological ideas more superficially, as novices do, or based on deeper concepts, like experts. The frequency with which ICB students connected deep-concept pairs, or triplets, was similar to peers; but deep understanding of structure/function was much higher (for pairs: 77% vs. 25%, p < 0.01). 3) A content-focused Medical College Admission Test (MCAT) posttest compared ICB student content knowledge with that of peers from 15 prior years. Historically, MCAT performance for each semester ranged from 53% to 64%; the ICB cohort scored 62%, in the top quintile. Longitudinal tracking in five upper-level science courses the following year found ICB students outperformed peers in physiology (85% vs. 80%, p < 0.01). PMID:28389429

Middle school sexual harassment, violence and social networks.
Mumford, Elizabeth A; Okamoto, Janet; Taylor, Bruce G; Stein, Nan
2013-11-01
To pilot a study of social networks informing contextual analyses of sexual harassment and peer violence (SH/PV). Seventh and 8th grade students (N = 113) in an urban middle school were surveyed via a Web-based instrument. Boys and girls reported SH/PV victimization and perpetration at comparable rates. The proportion of nominated friends who reported SH/ PV outcomes was greater in boys' than in girls' social networks. Structural descriptors of social networks were not significant predictors of SH/PV outcomes. Collection of sensitive relationship data via a school-based Web survey is feasible. Full-scale studies and greater flexibility regarding the number of friendship nominations are recommended for subsequent investigations of potential sex differences.

To analyze self-esteem, as well as the different peer influence components (messages, interactions and likability) as predictors of body dissatisfaction in children with obesity. A total of 123 children aged between 10 and 12 years were divided into two groups according to their body mass index. The group with obesity was comprised of 36 boys and 21 girls and the group with normal weight of 32 boys and 34 girls. All of the participants answered the Body Shape Questionnaire-16, the Inventory of Peer Influence on Eating Concerns, and the Rosenberg Self-Esteem Scale. The hierarchical multiple regression analysis for each group showed that likability and peer messages explain 67% of the body dissatisfaction variance in children with obesity and 54% in children with normal weight. Peer influence predicted body dissatisfaction in children; however, children with obesity assimilate messages from their peers differently compared with children with normal weight.

Efforts to assess forest ecosystem carbon stocks, biodiversity, and fire hazards have spurred the need for comprehensive assessments of forest ecosystem dead wood (DW) components around the world. Currently, information regarding the prevalence, status, and methods of DW inventories occurring in the world's forested landscapes is scattered. The goal of this study is to describe the status, DW components measured, sample methods employed, and DW component thresholds used by national forest inventories that currently inventory DW around the world. Study results indicate that most countries do not inventory forest DW. Globally, we estimate that about 13% of countries inventory DW using a diversity of sample methods and DW component definitions. A common feature among DW inventories was that most countries had only just begun DW inventories and employ very low sample intensities. There are major hurdles to harmonizing national forest inventories of DW: differences in population definitions, lack of clarity on sample protocols/estimation procedures, and sparse availability of inventory data/reports. Increasing database/estimation flexibility, developing common dimensional thresholds of DW components, publishing inventory procedures/protocols, releasing inventory data/reports to international peer review, and increasing communication (e.g., workshops) among countries inventorying DW are suggestions forwarded by this study to increase DW inventory harmonization.

Applying resource control theory and social exchange theory, we examined the social network conditions under which elementary age children were likely to engage in relational aggression. Data on classroom peer networks and peer-nominated behaviors were collected on 671 second- through fourth-grade children in 34 urban, low-income classrooms. Nested regression models with robust cluster standard errors demonstrated that the association between children's number of relationships and their levels of relational aggression was moderated by the number of relationships that their affiliates had. Children with more peer relationships (i.e., higher network centrality) exhibited higher levels of relational aggression, but only when these relationships were with peers who had fewer connections themselves (i.e., poorly connected peers). This finding remained significant even when controlling for common predictors of relational aggression including gender, overt aggression, prosocial behavior, victimization, social preference, and perceived popularity. Results are discussed in terms of their implications for advancing the literature on childhood relational aggression and their practical applications for identifying children at risk for these behaviors. © 2012 Wiley Periodicals, Inc.

Aggression jeopardizes positive development in children and predicts social and academic maladjustment in school. The present study determined the relationships among anger dysregulation (a marker of emotion regulation), cortisol activity (a biomarker of stress), and peer-nominated aggression in typically developing children in their everyday classroom setting (N = 151, Mean age = 10.86, SD =.74). Salivary cortisol was collected at 09:15, 11:45, and 14:45 hr across 4 consecutive days. Children provided self-reports of anger regulation; peers reported proactive and reactive aggressive behaviors. Hierarchical linear regression analyses, followed by a bootstrapping analysis identified basal afternoon cortisol as a significant mediator between anger regulation and peer-reported aggression. More dysregulated anger significantly predicted lower afternoon cortisol, which in turn predicted increased peer-reported aggression. These results align with previous research on links among hypocortisolism, emotional regulation, and behavior, and suggest a possible meditational pathway between emotion and behavior regulation via decreased afternoon cortisol levels. © 2017 Wiley Periodicals, Inc.

Parenting is often implicated as a potential source of individual differences in youths’ emotional information processing. The present study examined whether parental affect is related to an important aspect of adolescent emotional development, response to peer evaluation. Specifically, we examined relations between maternal negative affect, observed during parent–adolescent discussion of an adolescent-nominated concern with which s/he wants parental support, and adolescent neural responses to peer evaluation in 40 emotionally healthy and depressed adolescents. We focused on a network of ventral brain regions involved in affective processing of social information: the amygdala, anterior insula, nucleus accumbens, and subgenual anterior cingulate, as well as the ventrolateral prefrontal cortex. Maternal negative affect was not associated with adolescent neural response to peer rejection. However, longer durations of maternal negative affect were associated with decreased responsivity to peer acceptance in the amygdala, left anterior insula, subgenual anterior cingulate, and left nucleus accumbens. These findings provide some of the first evidence that maternal negative affect is associated with adolescents’ neural processing of social rewards. Findings also suggest that maternal negative affect could contribute to alterations in affective processing, specifically, dampening the saliency and/or reward of peer interactions during adolescence.

Research suggests that heavy episodic drinking (HED), perceived peer norms, and personal approval of aggression influence male barroom aggression (MBA). Qualitative research suggests that conformity to hegemonic masculine gender norms also influences MBA; however, quantitative research on the direct and indirect influence of masculinity on MBA is limited. This study tested the relationships between HED, conformity to masculine gender norms, and personal approval and peer approval of MBA on MBA perpetration, as well as the indirect effect of masculine norms on MBA via HED. A convenience sample of Australian men (N = 322; mean age = 21.05 years, SD = 1.95; 76.9% university students) completed an online questionnaire, assessing HED and MBA over the previous year, and subscales of the Beliefs and Attitudes Towards Male Alcohol-Related Aggression Inventory and Conformity to Masculine Norms Inventory-46. Negative binomial regression analyses found that, overall, HED, male peer approval, and personal approval of MBA directly predicted increased risk of verbal and physical MBA perpetration. Greater conformity to specific masculine norms also increased (Power Over Women) and decreased (Emotional Control, Heterosexual Self-Presentation) risk of MBA perpetration. The masculine norms Risk Taking, Playboy, and Emotional Control were found to be indirect predictors of MBA via HED. Risk of MBA perpetration is increased primarily by HED as a direct, but also mediating, predictor. Personal and male peer approval of MBA, and specific masculine norms, further increase this risk whereas other masculine norms appear protective.

Research has revealed significant heterogeneity in the group-level peer outcomes associated with anxious-withdrawal, but little is known about possible sources of this heterogeneity during early adolescence. This study of 271 young adolescents (49 % female; M age = 11.54 years) examined whether the concurrent and short-term longitudinal (3 month period) associations between peer-nominated anxious-withdrawn behaviors and three group-level peer outcomes (overt victimization, peer acceptance, popularity) varied as a function of peer-valued characteristics (humor, prosocial behavior, physical attractiveness, athletic ability) and gender, after accounting for the effects of involvement in mutual friendships. Regression analyses revealed that the associations between anxious-withdrawal and peer outcomes were moderated by peer-valued characteristics and, in many cases, gender. For example, anxious-withdrawal was related positively to overt victimization for all adolescents who were high in prosocial behavior. But, anxious-withdrawal was related negatively to popularity for adolescent boys who were high in prosocial behavior and adolescent girls who were low in prosocial behavior. Anxious-withdrawal also predicted increases in acceptance for adolescent girls who were high in humor, but decreases in acceptance for adolescent boys who were high in humor. Several additional moderator effects were found for boys only. The findings highlight the importance of considering the unique constellation of characteristics displayed by anxious-withdrawn young adolescents in studies on peer experiences at the group-level of social complexity.

Research on gaming effects has focused on adolescence, a developmental period in which peer relationships become increasingly salient. However, the impact of peers on the effects of violent gaming on adolescents has been understudied. This study examined whether adolescents’ exposure to violent video games predicted their own and their friend's aggression one year later. Among 705 gaming adolescents, 141 dyads were identified based on reciprocated best friend nominations (73.8% male, Mage = 13.98). Actor‐Partner Interdependence Models indicated that adolescent males’ (but not females’) exposure to violent games positively predicted the aggression of their best friend 1 year later. This effect appeared regardless of whether the friends played video games together or not. The study illustrates the importance of peers in the association between violent gaming and aggression.

Using a 3-wave longitudinal, multidimensional approach, this study investigated the influence of social network position and social status on psychosocial outcomes of 440 youth (45.1% girls; Mage = 16.1; 90.9% Caucasian) over 26 months, focusing on the controversial status classification (i.e., youth who are both highly liked and disliked by their peers). Brokerage (i.e., the degree to which a person has relationships with peers who do not have a direct relationship with each other) was examined in conjunction with sociometric status to explain potential heterogeneity of outcomes for controversial status youth. Adolescents completed peer nominations and self-reports of adjustment. Results demonstrated that brokerage related to poorer psychosocial outcomes for controversial than average status youth. Brokerage appears to add predictive value to youths’ adjustment beyond traditional sociometric classifications, especially for controversial status youth. PMID:27428447
Level I water-quality inventory and monitoring, Richmond National Battlefield Park, Virginia

2002-01-01
The U.S. Geological Survey conducted a Level I Water-Quality Inventory and Monitoring (WAQIM) data-collection effort for Richmond National Battlefield Park (Richmond NBP) from August 2001 through April 2002. The primary objective of the WAQIM program was to provide the National Park Service (NPS) and Richmond NBP with at least a nominal inventory of its natural resources and to provide those data in a data-management system consistent with park management needs. Water-quality inventory data (physical, chemical, and biological) were collected from "key" water bodies within the boundaries of Richmond NBP. The key water bodies are those waters within park boundaries that are essential to the central cultural, historical or natural resources management themes of the parks or provide habitats to threatened or endangered plants and animals. Data were collected during the fall, winter, spring, and summer over a range of hydrologic conditions. Because of the drought conditions that persisted during the study period, variations in flow between seasons were less pronounced than during normal hydrologic conditions.

Objective In contrast to prior work, recent theory suggests that high, not low, levels of adolescent peer popularity may be associated with health risk behavior. This study examined (a) whether popularity may be uniquely associated with cigarette use, marijuana use, and sexual risk behavior, beyond the predictive effects of aggression; (b) whether the longitudinal association between popularity and health risk behavior may be curvilinear; and (c) gender moderation. Methods A total of 336 adolescents, initially in 10–11th grades, reported cigarette use, marijuana use, and number of sexual intercourse partners at two time points 18 months apart. Sociometric peer nominations were used to examine popularity and aggression. Results Longitudinal quadratic effects and gender moderation suggest that both high and low levels of popularity predict some, but not all, health risk behaviors. Conclusions New theoretical models can be useful for understanding the complex manner in which health risk behaviors may be reinforced within the peer context. PMID:21852342

Psychopathic traits moderate peer influence on adolescent delinquency.

Peer influence on adolescent delinquency is well established, but little is known about moderators of peer influence. In this study, we examined adolescents' (targets) and their peers' psychopathic personality traits as moderators of peer influence on delinquency in peer networks. We used three separate dimensions of the psychopathic personality: grandiose-manipulative traits, callous-unemotional traits, and impulsive-irresponsible traits. We used a peer network approach with five waves of longitudinal data from 847 adolescents in one community. Peer nominations were not limited to the school context, thus allowing us to capture all potentially important peers. In addition, peers reported on their own delinquency, thus allowing us to avoid problems of false consensus or projection that arise when individuals report on their peers' delinquency. We used simulation investigation for empirical network analyses (SIENA), which is the only program currently available that can be used to study peer influence effects in peer networks of multiple relationships while controlling for selection effects. Targets' and peers' callous-unemotional and grandiose-manipulative traits uniquely moderated peer influence on delinquency. Relative to those with low levels, targets who were high on these traits were less influenced by peers' delinquency, and peers who were high on these traits were more influential on targets' delinquency. Selection effects were found for impulsive-irresponsible traits, but these traits did not moderate peer influence on delinquency. As the first study to look at moderating effects of psychopathic traits on peer influence, this study advances knowledge about peer influence on delinquency and about psychopathic traits in adolescents. In addition, the study contributes to the literature by looking at unique effects of the three dimensions of psychopathy and taking a peer network approach, in which network effects, self-selection, and other selection effects are controlled when examining influence and moderators of influence. © 2011 The Authors.

This short-term longitudinal study examined the associations among relational aggression, physical aggression, and peer status (i.e., acceptance, rejection, and perceived popularity) across three time points, six months apart, in a Taiwanese sample. Participants were 198 fifth grade students (94 girls and 104 boys; Mean age = 10.35 years) from Taipei, Taiwan. Study variables were assessed using peer nomination procedure. Results from the cross-lagged structural equation models demonstrated that there were longitudinal associations between relational aggression and each of the peer status constructs while only one longitudinal association was found for physical aggression such that physical aggression positively predicted subsequent peer rejection. The longitudinal associations did not vary with gender. Results also showed high stabilities of relational aggression, physical aggression, and the three peer status constructs over 1 year as well as high concurrent association between relational and physical aggression. In addition, relational aggression and physical aggression were concurrently related to less acceptance, more rejection, and less perceived popularity, especially at the outset of the study. Findings of this study demonstrated both similarities and differences in relation to previous literature in primarily Western cultures. This study also highlights the bidirectional and complex nature of the association between aggression and peer status, which appears to depend on the form of aggression and on the particular indicator of peer status under study.

To examine the psychometric properties of the Patient-Reported Outcomes Measurement Information System (PROMIS®) peer relationships short form (PR-SF), including association with peer-reported friendships, likeability, and social reputation. 203 children (Mage = 10.12 years, SD = 2.37, range = 6-14) in Grades 1-8 completed the 8-item PR-SF and friendship nominations, like ratings, and social reputation measures about their peers during 2 classroom visits approximately 4 months apart, as part of a larger study. A confirmatory factor analysis, followed by an exploratory factor analysis, was conducted to examine the factor structure of the PR-SF. Spearman correlations between the PR-SF and peer-reported outcomes evaluated construct validity. For the PR-SF, a 2-factor solution demonstrated better fit than a 1-factor solution. The 2 factors appear to assess friendship quality (3 items) and peer acceptance (5 items). Reliability was marginal for the friendship quality factor (.66) but adequate for the acceptance factor (.85); stability was .34 for the PR-SF over 4 months. The PR-SF (8 items) and acceptance factor (5 items) both had modest but significant correlations with measures of friendship (rs = .25-.27), likeability (rs = .21-.22), and social reputation (rs = .29-.44). The PR-SF appears to be measuring two distinct aspects of social functioning. The 5-item peer acceptance scale is modestly associated with peer-reported friendship, likeability, and social reputation. Although not a replacement for peer-reported outcomes, the PR-SF is a promising patient-reported outcome for peer relationships in youth.

Although research on social embeddedness and social capital con-firms the value of friendship networks, little has been written about how social relations form and are structured by social institutions. Using data from the Adolescent Health and Academic Achievement study and the National Longitudinal Study of Adolescent Health, the authors show that the odds of a new friendship nomination were 1.77 times greater within clusters of high school students taking courses together than between them. The estimated effect cannot be attributed to exposure to peers in similar grade levels, indirect friendship links, or pair-level course overlap, and the finding is robust to alternative model specifications. The authors also show how tendencies associated with status hierarchy inhering in triadic friendship nominations are neutralized within the clusters. These results have implications for the production and distribution of social capital within social systems such as schools, giving the clusters social salience as “local positions.” PMID:25364011

This study sought to expand on prior research suggesting that children low in peer status who either over- or underestimate their social competence relative to others' reports are more likely to be aggressive (White and Kistner [2011]. Journal of Abnormal Child Psychology, 39, 645-656). The curvilinear associations between social competence bias and two forms of aggression (physical and relational) were examined in a sample of 4th through 6th graders (n = 183); moderation by both sex and peer status (peer preference and popularity) also were tested. Social competence bias was operationally defined as the residual difference between child and teacher ratings of the child's social competence. Aggression and peer status were measured using peer nomination procedures. There was a significant curvilinear association between social competence bias and physical aggression moderated by both types of peer status. For low peer status children greater underestimation and overestimation of social competence was associated with higher physical aggression. The curvilinear association between social competence bias and relational aggression was moderated by both peer status and sex. Popular boys had higher rates of relational aggression when they had accurate, rather than biased, self-perceptions of social competence. However, for very highly preferred girls, a more extreme positive bias was associated with an exponential increase in relational aggression. Results are discussed in terms of implications for aggression theory and intervention. © 2014 Wiley Periodicals, Inc.

The influences of peer relationships on adolescent subjective well-being were investigated within the framework of social network analysis, using exponential random graph models as a methodological tool. The participants in the study were 1,279 students (678 boys and 601 girls) from nine junior middle schools in Shenzhen, China. The initial stage of the research used a peer nomination questionnaire and a subjective well-being scale (used in previous studies) to collect data on the peer relationship networks and the subjective well-being of the students. Exponential random graph models were then used to explore the relationships between students with the aim of clarifying the character of the peer relationship networks and the influence of peer relationships on subjective well being. The results showed that all the adolescent peer relationship networks in our investigation had positive reciprocal effects, positive transitivity effects and negative expansiveness effects. However, none of the relationship networks had obvious receiver effects or leaders. The adolescents in partial peer relationship networks presented similar levels of subjective well-being on three dimensions (satisfaction with life, positive affects and negative affects) though not all network friends presented these similarities. The study shows that peer networks can affect an individual's subjective well-being. However, whether similarities among adolescents are the result of social influences or social choices needs further exploration, including longitudinal studies that investigate the potential processes of subjective well-being similarities among adolescents.

Exponential random graph models were then used to explore the relationships between students with the aim of clarifying the character of the peer relationship networks and the influence of peer relationships on subjective well being. The results showed that all the adolescent peer relationship networks in our investigation had positive reciprocal effects, positive transitivity effects and negative expansiveness effects. However, none of the relationship networks had obvious receiver effects or leaders. The adolescents in partial peer relationship networks presented similar levels of subjective well-being on three dimensions (satisfaction with life, positive affects and negative affects) though not all network friends presented these similarities. The study shows that peer networks can affect an individual’s subjective well-being. However, whether similarities among adolescents are the result of social influences or social choices needs further exploration, including longitudinal studies that investigate the potential processes of subjective well-being similarities among adolescents.

Psychological characteristics of self-harming behavior in Korean adolescents.
Lee, Woo Kyeong
2016-10-01
Recently, self-injury is drawing the attention of researchers and clinicians. The purpose of this study was to investigate the prevalence and psychological characteristics of adolescents who engage in self-harm and to examine the risk factors for engaging in this harmful behavior among Korean mid-adolescents. Participants were 784 adolescents aged 13-15 years. They completed self-report questionnaires that assessed (1) Non-Suicidal Self-Injury: the Self-Harm Questionnaire, Toronto Alexithymia Scale; (2) depression: Children's Depression Inventory; (3) adolescent-parent relationship: Parental Bonding Instrument; (4) peer attachment: Inventory of Parent and Peer Attachment; and (5) academic stress. Overall, 12.4% (n=97) of participants reported engaging in self-destructive behavior at least once in their lives. The primary reason for engaging in self-harm was to regulate negative emotions such as anger and sadness. As expected, the self-harm group showed statistically significant higher levels of academic stress, alexithymia, depression, and poor relationships with their parents and peers. Stepwise multiple regression analysis showed that alexithymia, depression, and peer relations were significant predictors of self-harming behavior. Given that the primary reason for engaging in self-harm is to cope with negative emotions, mental health professionals in school settings should regularly evaluate self-injurious behavior and provide prevention programs for adolescents at risk.

The present study introduces the Children's Daily Stress Inventory (Inventario Infantil de Estresores Cotidianos, IIEC) as a measure that assesses daily stress in primary school children. The inventory was applied to a sample of 1094 primary school students. The final version includes 25 dichotomic items covering the areas of health, school/peers, and family. The score is obtained by adding the total of positive answers. Analyses of items, reliability and several external pieces of evidence of validity based on relations with other variables are presented. The results show adequate psychometric properties for the assessment of daily stress in children.
Attentional deficits with and without hyperactivity: teacher and peer perceptions.
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 on gaming effects has focused on adolescence, a developmental period in which peer relationships become increasingly salient. However, the impact of peers on the effects of violent gaming on adolescents has been understudied. This study examined whether adolescents' exposure to violent video games predicted their own and their friend's aggression one year later. Among 705 gaming adolescents, 141 dyads were identified based on reciprocated best friend nominations (73.8% male, M age = 13.98). Actor-Partner Interdependence Models indicated that adolescent males' (but not females') exposure to violent games positively predicted the aggression of their best friend 1 year later. This effect appeared regardless of whether the friends played video games together or not. The study illustrates the importance of peers in the association between violent gaming and aggression. © 2018 The Authors. Aggressive Behavior Published by Wiley Periodicals, Inc.

Two-part latent growth models examined associations between two forms of peer status (popularity, likability) and adolescents' alcohol use trajectories throughout high school; ethnicity was examined as a moderator. Ninth-grade low-income adolescents (N = 364; Mage = 15.08; 52.5% Caucasian; 25.8% African American; 21.7% Latino) completed sociometric nominations of peer status and aggression at baseline, and reported their alcohol use every 6 months. After controlling for gender, aggression, ethnicity, and socioeconomic status, popularity-but not likability-prospectively predicted alcohol use trajectories. However, these effects were moderated by ethnicity, suggesting popularity as a risk factor for alcohol use probability and frequency among Caucasian and Latino, but not African American adolescents. Results suggest that developmental correlates of peer status should be considered within cultural context. © 2015 The Authors. Child Development © 2015 Society for Research in Child Development, Inc.
Development of leadership behaviors in undergraduate nursing students: a service-learning approach.
Foli, Karen J; Braswell, Melanie; Kirkpatrick, Jane; Lim, Eunjung
2014-01-01
The purpose of this study was to determine leadership behaviors developed by nursing students and peers before and after a service-learning experience. Nurses have been called to fill growing needs in the health care setting, rendering care to vulnerable and diverse populations in a wide range of organizations. Leadership behaviors are therefore essential. Baccalaureate students (N = 65) completed the Student Leadership Practices Inventory-Self at the beginning and end of the semester. The students also rated peers using the Leadership Practices Inventory-Observer and answered six questions about service-learning. Repeated measures of analysis of variance for pre- and posttests revealed that leadership behaviors improved (p < .0001). A significant correlation was found (p = .02) between the overall posttest scores for both instruments. CONCLUSION Integrating service-learning into a leadership course is an effective approach to the development of leadership behaviors.

Parenting is often implicated as a potential source of individual differences in youths' emotional information processing. The present study examined whether parental affect is related to an important aspect of adolescent emotional development, response to peer evaluation. Specifically, we examined relations between maternal negative affect, observed during parent-adolescent discussion of an adolescent-nominated concern with which s/he wants parental support, and adolescent neural responses to peer evaluation in 40 emotionally healthy and depressed adolescents. We focused on a network of ventral brain regions involved in affective processing of social information: the amygdala, anterior insula, nucleus accumbens, and subgenual anterior cingulate, as well as the ventrolateral prefrontal cortex. Maternal negative affect was not associated with adolescent neural response to peer rejection. However, longer durations of maternal negative affect were associated with decreased responsivity to peer acceptance in the amygdala, left anterior insula, subgenual anterior cingulate, and left nucleus accumbens. These findings provide some of the first evidence that maternal negative affect is associated with adolescents' neural processing of social rewards. Findings also suggest that maternal negative affect could contribute to alterations in affective processing, specifically, dampening the saliency and/or reward of peer interactions during adolescence.

The present study examined direct and interactive links between friendships and social, academic, and psychological adjustment problems (i.e., peer rejection as nominated by same-ethnic and cross-ethnic peers, teacher-reported academic engagement, and teacher-reported internalizing symptoms) among school-age children in multiethnic schools (n = 509, age: 9-10). The data, which included 2 time points with a 6-month interval, were drawn from a relatively large-sized, short-term longitudinal study. Results showed that cross-ethnic friendships (not same-ethnic friendships) were associated with greater academic engagement concurrently and predated decreased peer rejection and internalizing symptoms longitudinally, even after controlling for the availability of same-ethnic peers and classroom diversity. Furthermore, cross-ethnic friendships (not same-ethnic friendships) moderated the link between relational victimization and increased peer rejection and greater internalizing symptoms, such that this link was evidenced for children with fewer cross-ethnic friendships. However, the moderation effect was contingent upon the type of outcome variables and the ethnicity of the child. For example, the buffering effect against the negative contribution of relational victimization to internalizing symptoms was found particularly for African American children. The findings are discussed based on theories of normative development, ethnic socialization, and intergroup relations. (c) 2015 APA, all rights reserved).

Predicting early adolescent gang involvement from middle school adaptation.
Dishion, Thomas J; Nelson, Sarah E; Yasui, Miwa
2005-03-01
This study examined the role of adaptation in the first year of middle school (Grade 6, age 11) to affiliation with gangs by the last year of middle school (Grade 8, age 13). The sample consisted of 714 European American (EA) and African American (AA) boys and girls. Specifically, academic grades, reports of antisocial behavior, and peer relations in 6th grade were used to predict multiple measures of gang involvement by 8th grade. The multiple measures of gang involvement included self-, peer, teacher, and counselor reports. Unexpectedly, self-report measures of gang involvement did not correlate highly with peer and school staff reports. The results, however, were similar for other and self-report measures of gang involvement. Mean level analyses revealed statistically reliable differences in 8th-grade gang involvement as a function of the youth gender and ethnicity. Structural equation prediction models revealed that peer nominations of rejection, acceptance, academic failure, and antisocial behavior were predictive of gang involvement for most youth. These findings suggest that the youth level of problem behavior and the school ecology (e.g., peer rejection, school failure) require attention in the design of interventions to prevent the formation of gangs among high-risk young adolescents.
Addressing challenges to MMPI-2-RF-based testimony: questions and answers.
Ben-Porath, Yossef S
2012-11-01
Introduction of a new version of a psychological test brings with it challenges that can be accentuated by the adversarial nature of the legal process. In the case of the Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF), these challenges can be addressed by becoming familiar with the rationale for and the methods used in revising the inventory, the information contained in the test manuals, and the growing peer-reviewed literature on the test. Potential challenges to MMPI-2-RF-based testimony are identified in this article and discussed in question and answer format. The questions guiding this discussion are based on the Daubert factors, established in 1993 by the US Supreme Court as criteria for gauging the scientific validity of proffered expert testimony. The answers to these questions apply more broadly to testimony in depositions, pre-trial hearings, and at trial. Consideration of the MMPI-2-RF in light of the Daubert factors indicates that the instrument has been subjected to extensive empirical testing and that a substantial peer-reviewed literature is available to guide and support its use. Information about the known and potential rate of error associated with MMPI-2-RF scores is available, and standard procedures for administration, scoring, and interpretation of the inventory are detailed in the test administration manual. Indicators of MMPI-2-RF acceptance can be cited, and criticisms of the MMPI-2-RF can be addressed with information available in the test documents and an extensive, modern, and actively growing peer-reviewed literature.

This study examines the social relationships of elementary school children with high-functioning autism, focusing on how gender relates to social preferences and acceptance, social connections, reciprocal friendships, and rejection. Peer nomination data were analyzed for girls with and without ASD (n = 50) and boys with and without ASD (n = 50). Girls and boys with ASD were matched by age, gender, and IQ. Each child with ASD was matched by age and gender to a typically developing classmate. Consistent with typically developing populations, children with ASD preferred, were accepted by, and primarily socialized with same-gender friends. With fewer nominations and social relationships, girls and boys with ASD appear more socially similar to each other than to the same-gender control group. Additionally, girls and boys with ASD showed higher rates of social exclusion than their typically developing peers. However, boys with ASD were more overtly socially excluded compared to girls with ASD, who seemed to be overlooked, rather than rejected. Our data suggest a number of interesting findings in the social relationships of children with ASD in schools. Like typically developing populations, children with ASD identify with their own gender when socializing and choosing friends. But given the social differences between genders, it is likely that girls with ASD are experiencing social challenges that are different from boys with ASD. Therefore, gender is an important environmental factor to consider when planning social skills interventions at school. © 2014 The Authors.

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.

Peer effects in adolescent cannabis are difficult to estimate, due in part to the lack of appropriate data on behaviour and social ties. This paper exploits survey data that have many desirable properties and have not previously been used for this purpose. The data set, collected from teenagers in three annual waves from 2002 to 2004 contains longitudinal information about friendship networks within schools (N = 5020). We exploit these data on network structure to estimate peer effects on adolescents from their nominated friends within school using two alternative approaches to identification. First, we present a cross-sectional instrumental variable (IV) estimate of peer effects that exploits network structure at the second degree, i.e. using information on friends of friends who are not themselves ego's friends to instrument for the cannabis use of friends. Second, we present an individual fixed effects estimate of peer effects using the full longitudinal structure of the data. Both innovations allow a greater degree of control for correlated effects than is commonly the case in the substance-use peer effects literature, improving our chances of obtaining estimates of peer effects than can be plausibly interpreted as causal. Both estimates suggest positive peer effects of non-trivial magnitude, although the IV estimate is imprecise. Furthermore, when we specify identical models with behaviour and characteristics of randomly selected school peers in place of friends', we find effectively zero effect from these 'placebo' peers, lending credence to our main estimates. We conclude that cross-sectional data can be used to estimate plausible positive peer effects on cannabis use where network structure information is available and appropriately exploited.

The Social Values of Aggressive-Prosocial Youth.
McDonald, Kristina L; Benish-Weisman, Maya; O'Brien, Christopher T; Ungvary, Stephen
2015-12-01
Recent research has identified youth who utilize both aggressive and prosocial behavior with peers. Although the social values and motivations associated with aggression and prosocial behavior have been well studied, the values of youth who utilize both aggression and prosocial behavior are unknown. The current study identified groups of adolescents based on peer nominations of aggression and prosocial behavior from both Israel (n = 569; 56.94% Arab, 43.06% Jewish; 53.78% female) and the United States (n = 342; 67.54% African-American; 32.46% European-American; 50.88% female). Self-enhancement, self-transcendence, openness-to-change, and conservation values predicted behavioral group membership. Power values predicted membership in the aggressive group relative to the aggressive-prosocial, prosocial, and low-both groups. For Israeli boys, openness-to-change values predicted membership in the aggressive-prosocial group relative to the prosocial group. The values of aggressive-prosocial youth were more similar to the values of prosocial peers than to aggressive peers, suggesting that motivational interventions for aggressive-prosocial youth should differ in important ways than those for aggressive youth.
Early childhood precursors and adolescent sequelae of grade school peer rejection and victimization.
Bierman, Karen L; Kalvin, Carla B; Heinrichs, Brenda S
2015-01-01
This study examined the early childhood precursors and adolescent outcomes associated with grade school peer rejection and victimization among children oversampled for aggressive-disruptive behaviors. A central goal was to better understand the common and unique developmental correlates associated with these two types of peer adversity. There were 754 participants (46% African American, 50% European American, 4% other; 58% male; average age=5.65 at kindergarten entry) followed into seventh grade. Six waves of data were included in structural models focused on three developmental periods. Parents and teachers rated aggressive behavior, emotion dysregulation, and internalizing problems in kindergarten and Grade 1 (Waves 1-2); peer sociometric nominations tracked "least liked" and victimization in Grades 2, 3, and 4 (Waves 3-5); and youth reported on social problems, depressed mood, school adjustment difficulties, and delinquent activities in early adolescence (Grade 7, Wave 6). Structural models revealed that early aggression and emotion dysregulation (but not internalizing behavior) made unique contributions to grade school peer rejection; only emotion dysregulation made unique contributions to grade school victimization. Early internalizing problems and grade school victimization uniquely predicted adolescent social problems and depressed mood. Early aggression and grade school peer rejection uniquely predicted adolescent school adjustment difficulties and delinquent activities. Aggression and emotion dysregulation at school entry increased risk for peer rejection and victimization, and these two types of peer adversity had distinct as well as shared risk and adjustment correlates. Results suggest that the emotional functioning and peer experiences of aggressive-disruptive children deserve further attention in developmental and clinical research.

The impact of gender and nationality on winning a professional society award

Women are under-represented for science awards and fellow status in professional science societies (accounting for career stage) and are over-represented for teaching and service awards (Ball et al., 2015; Lincoln et al., 2012; Holmes et al., 2011). In addition, for the American Geophysical Union, non-U.S. members are under-represented among all awardees. Gender bias in evaluation processes are well-documented (e.g., Valian, 1999), and cultural differences are at play in the under-representation of non U.S. members. U.S. members are more likely to nominate their peers for awards, and to write effusive letters to support the nomination (Ball et al., 2015). There are effective mechanisms to reduce bias in both nomination and evaluation processes, a few of which are: 1) separate the nomination and evaluation processes by creating nomination committees of a diverse group of people who actively seek potential nominees and promote their nominations; this expands the pool of nominees; 2) educate nomination and evaluation committees on the research that demonstrates the impact of implicit bias on nomination and selection processes (e.g., http://www.enei.org.uk/pages/unconscious-bias.html; http://wiseli.engr.wisc.edu/bias.php); 3) minimize use of simple bibliometric indices, which are known to exhibit gender bias (men self-cite more than women; Maliniak et al., 2013) and nationality bias (papers in English language journals are more likely to be cited than non-English journals (Bornmann et al., 2012; González-Alcaide et al., 2012); 4) members of the selection committee should understand the effects of gender on the quality of letters written for women (Trix and Psenka, 2003); 5) establish and follow clear criteria for the award. Professional societies can promote fairness and inclusion by self-study: find and compile the data on the gender, race, ethnicity and nationality of members who are nominated for and win awards, as well as on who is doing the nominating. Compare these data with membership demographics to reveal where in the awards process procedures could be improved. For the AGU, after working to enact the recommendations above for five years, we have begun to see an increase in the number of women nominated for and winning awards. Future efforts will include non-U.S. members as well.

Adolescence is an important developmental stage during which both peers and the media have a strong influence. Both peer rejection and the use of morally adverse media are associated with negative developmental outcomes. This study examines processes by which peer rejection might drive adolescents to select antisocial media content by tying together developmental research on peer rejection and research on media effects. Assumed underlying mechanisms are rejection-based anger and frustration and the adolescent's moral judgment. A between-participants experimental design manipulated peer rejection versus acceptance in adolescents (Mage = 13.88 years; N = 74) and young adults (Mage = 21.37 years; N = 75), applying the Cyberball paradigm. Measures included the State Anger Inventory (STAXI) to assess feelings of rejection and the newly devised Media, Morals, and Youth Questionnaire (MMaYQue) to assess media preferences and moral judgment of media content. Using bootstrapping analyses, a double mediation was established: Higher levels of state anger in peer-rejected adolescents induced more tolerable moral judgments of antisocial media content, subsequently instigating a preference for antisocial media content. In contrast, the young adult sample showed no relations between peer rejection and antisocial media preference. Results are discussed within a downward spiral framework of combined peer and media influences. PsycINFO Database Record (c) 2013 APA, all rights reserved

The goal of this study was to examine the extent to which preschoolers with externalizing behavior problems (EBP) can identify behaviors indicative of callous-unemotional (CU) traits among their peers. Participants for this study included 86 preschool children (69% boys; Mage = 5.07 years) with at-risk or clinically elevated levels of EBP who were attending a summer treatment camp. Data collected from the children, their peers, and the counselors who worked at the summer camp examined preschoolers' social preference, likability, and behaviors indicative of CU. Parents and preschool teachers also reported on children's CU traits and severity of behavioral impairment, as well as school readiness. Peer nominations of CU traits showed (a) excellent factor structure as evidenced by clear CU items (e.g., "don't feel bad when they do something wrong") versus more prosocial items ("share," "cooperate"); (b) moderate construct validity when compared to counselor reports of the CU factor as well as preschool teacher reported ratings of CU traits and severity of behavioral impairment; and (c) good utility as evidenced by associations with peer and counselor rated social preference, likability, and school readiness measures as rated by both parents and preschool teachers. These findings indicate that as early as preschool, children with EBP can identify peers who engage in behaviors indicative of CU traits, which have significant implications for children's social status and overall school readiness.
Mapping the spatial distribution of global anthropogenic mercury atmospheric emission inventories

Wilson, Simon J.; Steenhuisen, Frits; Pacyna, Jozef M.; Pacyna, Elisabeth G.
This paper describes the procedures employed to spatially distribute global inventories of anthropogenic emissions of mercury to the atmosphere, prepared by Pacyna, E.G., Pacyna, J.M., Steenhuisen, F., Wilson, S. [2006. Global anthropogenic mercury emission inventory for 2000. Atmospheric Environment, this issue, doi:10.1016/j.atmosenv.2006.03.041], and briefly discusses the results of this work. A new spatially distributed global emission inventory for the (nominal) year 2000, and a revised version of the 1995 inventory are presented. Emissions estimates for total mercury and major species groups are distributed within latitude/longitude-based grids with a resolution of 1×1 and 0.5×0.5°. A key component in the spatial distribution procedure is the use of population distribution as a surrogate parameter to distribute emissions from sources that cannot be accurately geographically located. In this connection, new gridded population datasets were prepared, based on the CEISIN GPW3 datasets (CIESIN, 2004. Gridded Population of the World (GPW), Version 3. Center for International Earth Science Information Network (CIESIN), Columbia University and Centro Internacional de Agricultura Tropical (CIAT). GPW3 data are available at http://beta.sedac.ciesin.columbia.edu/gpw/index.jsp).

Objective: The aim of this research was to obtain the views of young children regarding their reasons for rejecting a peer. Method: To achieve this goal, we conducted a qualitative study in the context of theory building research using an analysis methodology based on Grounded Theory. The collected information was extracted through semi-structured individual interviews from a sample of 853 children aged 6 from 13 urban public schools in Spain. Results: The children provided 3,009 rejection nominations and 2,934 reasons for disliking the rejected peers. Seven reason categories emerged from the analysis. Four categories refer to behaviors of the rejected children that have a cost for individual peers or peer group such as: direct aggression, disturbance of wellbeing, problematic social and school behaviors and dominance behaviors. A further two categories refer to the identities arising from the preferences and choices of rejected and rejecter children and their peers: personal identity expressed through preferences and disliking, and social identity expressed through outgroup prejudices. The "no-behavior or no-choice" reasons were covered by one category, unfamiliarity. In addition, three context categories were found indicating the participants (interpersonal-group), the impact (low-high), and the subjectivity (subjective-objective) of the reason. Conclusion: This study provides researchers and practitioners with a comprehensive taxonomy of reasons for rejection that contributes to enrich the theoretical knowledge and improve interventions for preventing and reducing peer rejection.

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).
Psychometric properties of the Violent Experiences Questionnaire.
King, Alan R; Russell, Tiffany D
2017-05-01
The Violent Experiences Questionnaire-Revised (VEQ-R) is a brief retrospective self-report inventory which provides estimates of annual frequencies of childhood physical abuse, sibling physical abuse, exposure to parental violence, peer bullying, and corporal punishment as they were experienced from ages 5 to 16. The VEQ-R indices rely on a frequency metric that estimates the number of days on average per year a specified class of behavior occurred over a 12year retrospective period. All scores range from a frequency of 0 to a high of 104. Scale normative data was generated from both a college (N=1266) and national (N=1290) sample to expand the research applicability of this relatively new inventory. Subscales were added to estimate the frequency of victimization during childhood, the pre-teen years, and adolescence. Four "hostility" component indices were derived from perpetrator source (parent, sibling, peer, or domestic). Thresholds were established to for High, Moderate, Low, and No Risk classifications. Subscales dimensions were found to have both adequate internal and temporal consistency. Evidence of concurrent and discriminant validity was generated using the Parent-Child Conflict Tactics Scale-Short-Form © , LONGSCAN Physical Abuse Self-Report scale, and Physical Punishment scale of the Assessing Environments III inventory.

Objective: There is strong evidence that depression anticipates later drinking problems among adults. These associations have not been consistently documented during adolescence, perhaps because little attention has been given to individual differences in peer relationships, which are the primary setting for adolescent alcohol consumption. This study investigated associations between depressive affect and alcohol misuse as moderated by peer group acceptance. Method: A community sample of 1,048 Swedish youth provided self-reports of depressive symptoms and intoxication frequency at annual intervals across the middle school years (seventh grade: M = 13.21 years old; eighth grade: M = 14.27 years old; ninth grade: M = 15.26 years old). Peer nominations provided a measure of individual acceptance. Results: Growth curve analyses revealed differences in the extent to which initial levels of depressive symptoms predicted the slope of increase in intoxication frequency. Higher levels of depressive symptoms at the outset anticipated sharp increases in intoxication frequency from seventh to ninth grades for low-accepted youth but not for average- or high-accepted youth. Conclusions: poor peer relations and depressive affect are vulnerabilities that set the stage for escalating adolescent alcohol misuse. Across the middle school years, when most youth have their first experiences with alcohol, peer difficulties exacerbated the tendency of depressed youth to drink to excess. PMID:26098034
Male Peer Support to Hostile Sexist Attitudes Influences Rape Proclivity.
Durán, Mercedes; Megías, Jesús L; Moya, Miguel
2018-07-01
Sexual assault affects a large proportion of women in the world. Although most rapes are committed by one man, the act itself may be influenced by many (e.g., the peer group). Hostile sexism (HS) has repeatedly been associated with men's rape proclivity, but the influence exerted by the HS of the peer group on rape proclivity has not been investigated. In this study, we explored the impact of perceived male peer support to HS on participants' rape proclivity. A sample of Spanish undergraduate students from a university in the south of Spain ( N = 134) completed the Ambivalent Sexism Inventory. Immediately afterwards, they received feedback on the supposed sexist responses of a peer group (high vs. low in HS); we kept the benevolent sexism (BS) of the peer group at medium levels. Next, we assessed participants' rape proclivity using acquaintance rape scenarios. Results showed an interaction between participants' own levels of HS and information about the HS of the peer group. Men high in HS reported higher rape proclivity in the high-HS peer-group condition than in the low-HS peer-group condition. By contrast, information on the peer group did not affect self-reported rape proclivity of men low in HS. Results also corroborated the relationship between participants' levels of HS and rape proclivity, and expanded the literature by revealing an unexpected influence of participants' BS on rape proclivity.

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.
Brief Report: Examining Executive and Social Functioning in Elementary-Aged Children with Autism.

There is a paucity of literature examining the relationship between executive and social functioning in children with autism spectrum disorder (ASD). Twenty-three school-aged children with ASD participated. Executive functioning was measured using the Developmental Neuropsychological Assessment, Second Edition and Differential Ability Scales, Second Edition, and the teacher-rated Behavior Rating of Inventory of Executive Function. Independent assessors observed children's social functioning on the playground while children with ASD and their peers completed a survey to measure peer friendships and rejections. Overall, poorer executive functioning was associated with increased playground isolation and less engagement with peers. This suggests that metacognitive skills such as initiation, working memory, and planning and organization are associated with children's social functioning.

Self-esteem is implied as a factor in the development of eating disorders. In adolescence peers have an increasing influence. Support for the role of self-esteem in eating disorders is ambiguous and little is known about the influence of social status as judged by others. The present study investigates whether self-esteem and peer status in early adolescence are associated with eating pathology in young adulthood. This study is part of TRAILS, a longitudinal cohort study on mental health and social development from preadolescence into adulthood. At age 11, participants completed the Self-Perception Profile for Children, assessing global self-esteem and self-perceptions regarding social acceptance, physical appearance, and academic competence. At age 13, peer status among classmates was assessed regarding likeability, physical attractiveness, academic performance, and popularity in a subsample of 1,007 participants. The Eating Disorder Diagnostic Scale was administered at age 22. The present study included peer-nominated participants with completed measures of self-perception at age 11 and eating pathology at age 22 (N = 732; 57.8% female). In a combined model, self-perceived physical attractiveness at age 11 and peer popularity at age 13 were inversely correlated with eating pathology at 22 years, while likeability by peers at age 13 was positively related to eating pathology. Both self-perceptions and peer status in early adolescence are significant predictors of eating pathology in young adults. Specific measures of self-esteem and peer-perceived status may be more relevant to the prediction of eating pathology than a global measure of self-esteem. © 2018 The Authors International Journal of Eating Disorders Published by Wiley Periodicals, Inc.

Peer surgical coaching is a promising approach for continuing professional development. However, scant guidance is available for surgeons seeking to develop peer-coaching skills. Executive coaching research suggests that effective coaches first establish a positive relationship with their coachees by aligning role and process expectations, establishing rapport, and cultivating mutual trust. To identify the strategies used by peer surgical coaches to develop effective peer-coaching relationships with their coachees. Drawing on executive coaching literature, a 3-part framework was developed to examine the strategies peer surgical coaches (n = 8) used to initially cultivate a relationship with their coachees (n = 11). Eleven introductory 1-hour meetings between coaching pairs participating in a statewide surgical coaching program were audiorecorded, transcribed, and coded on the basis of 3 relationship-building components. Once coded, thematic analysis was used to organize coded strategies into thematic categories and subcategories. Data were collected from October 10, 2014, to March 20, 2015. Data analysis took place from May 26, 2015, to July 20, 2016. Strategies and potentially counterproductive activities for building peer-coaching relationships in the surgical context to inform the future training of surgical coaches. Coaches used concrete strategies to align role and process expectations about the coaching process, to establish rapport, and to cultivate mutual trust with their coachees during introductory meetings. Potential coaching pitfalls are identified that could interfere with each of the 3 relationship-building components. Peer-nominated surgical coaches were provided with training on abstract concepts that underlie effective coaching practices in other fields. By identifying the strategies used by peer surgical coaches to operationalize these concepts, empirically based strategies to inform other surgical coaching programs are provided.

Examine the moderating effects of response inhibition on the longitudinal association between social preference/relational aggression measured in childhood, and intimate partner violence (IPV) measured in young adulthood, among women with ( n = 140) and without ( n = 88) histories of childhood ADHD. During childhood, social preference was measured through confidential peer sociometric nominations, yielding negative and positive peer regard; relational aggression was assessed via staff behavioral observations; and response inhibition was assessed using commission errors from the continuous performance task. During young adulthood, IPV was ascertained via a clinician-administered, semistructured interview. Social preference and relational aggression independently predicted IPV; this prospective link was moderated by response inhibition. In combination with low social preference or high relational aggression in childhood, poor response inhibition predicted the highest levels of young-adult IPV. Given the developmental significance of peer relationships, additional research on the causes of and treatments for poor social functioning in ADHD is warranted.

This study investigated the oxytocin receptor (OXTR) gene's moderation of associations between exposure to a substance misuse intervention, average peer substance use, and adolescents' own alcohol use during the 9th-grade. OXTR genetic risk was measured using five single nucleotide polymorphisms (SNPs), and peer substance use was based on youths' nominated closest friends' own reports of alcohol, cigarette, and marijuana use, based on data from the PROSPER project. Regression models revealed several findings. First, low OXTR risk was linked to affiliating with friends who reported less substance use in the intervention condition but not the control condition. Second, affiliating with high substance-using friends predicted youth alcohol risk regardless of OXTR risk or intervention condition. Third, although high OXTR risk youth in the intervention condition who associated with low substance-using friends reported somewhat higher alcohol use than comparable youth in the control group, the absolute level of alcohol use among these youth was still among the lowest in the sample.
Bully/Victim Profiles’ Differential Risk for Worsening Peer Acceptance: The Role of Friendship

Study aims were to: (1) evaluate the association between bully/victim profiles, derived via latent profile analysis (LPA), and changes in peer acceptance from the fall to spring of 7th grade, and (2) investigate the likelihood of friendlessness, and the protective function of mutual friendship, among identified profiles. Participants were 2,587 7th graders; peer nomination and rating-scale data were collected in the fall and spring. Four profiles, including bullies, victims, bully-victims, and uninvolved adolescents, were identified at each time point. Findings showed that for victims, more so than for bullies and uninvolved profiles, acceptance scores worsened over time. Results further revealed that bully-victim and victim profiles included a greater proportion of friendless youth relative to the bully profile, which, in turn, contained a greater proportion of friendless adolescents than the uninvolved profile. Findings also provided evidence for the buffering role of friendship among all bully/victim profiles and among bully-victims especially. PMID:26309346

Objective. To assess the development of knowledge, attitudes, and behaviors for collaborative practice among first-year pharmacy students following completion of interprofessional education. Methods. A mixed-methods strategy was employed to detect student self-reported change in knowledge, attitudes, and behaviors. Validated survey tools were used to assess student perception and attitudes. The Nominal Group Technique (NGT) was used to capture student reflections and provide peer discussion on the individual IPE sessions. Results. The validated survey tools did not detect any change in students’ attitudes and perceptions. The NGT succeeded in providing a milieu for participating students to reflect on their IPE experiences. The peer review process allowed students to compare their initial perceptions and reactions and renew their reflections on the learning experience. Conclusion. The NGT process has provided the opportunity to assess the student experience through the reflective process that was enriched via peer discussion. Students have demonstrated more positive attitudes and behaviors toward interprofessional working through IPE. PMID:28381886
Defending Victims of Bullying in Early Adolescence: A Multilevel Analysis.
Yun, Hye-Young; Graham, Sandra
2018-05-29
Adolescents' defending behaviors in school bullying situations is likely determined by individual characteristics, social status variables, and classroom/school contextual factors operating simultaneously in the peer ecology. However, there is little research on defending behavior that utilizes this multilevel approach. This study investigated how students' willingness to defend victims of bullying was affected by feelings of empathy, perceived popularity, and classroom-level perceived prosocial norms. Participants were 1373 adolescents (40% girls, Mage: 14 yrs) from 54 classrooms in six middle schools in South Korea. These youth reported on their feelings of empathy and how prosocial they perceived their classmates to be. Peer-ratings and peer nominations were used to estimate defending behaviors and which students were perceived as popular. Multilevel analyses showed that participants were more likely to defend victims when they had greater empathy and perceived popularity and when classroom-level prosocial norms were higher. The findings have implications for interventions to reduce school bullying and for studying defending behavior in multiple cultural contexts.

Objective: Core alexithymic features, such as the difficulty in identifying and describing feelings, are associated with poor attachment styles and emotional trauma, which influence the capacity to regulate affect. Additionally, emotional regulation has been found to be the most commonly identified function associated with non-suicidal self-injury behavior (NSSI) in adolescents as they attempt to modulate strong emotions. However, few studies have examined the link between difficulty in identifying and describing feelings (core components of alexithymia), NSSI behaviors, quality of attachment, life stressors and suicidal ideation in healthy early adolescents. Consequently, this study aims to investigate these constructs and the relationship among them in a large non-clinical sample of adolescents. Methods: Seven hundred and nine middle school students (50.4% males), aged 10-15 years ( M = 12.6; SD = 1.06) were involved in this study. In order to investigate the variables considered in the study, the following measures were administered: the Deliberate Self-Harm Inventory exploring non-suicidal self-injurious behaviors; the Alexithymia Questionnaire for Children examining difficulty in identifying and describing feelings; the Inventory of Parent and Peer Attachment assessing the quality of parental and peer attachment; the Life Stressor Checklist-Revised outlining stressful/traumatic events and the Children's Depression Inventory evaluating suicidal ideation. Results: We found significantly positive relationships among difficulty in identifying and describing feelings, NSSI behaviors, stressful events, and suicidal ideation. Data indicated a significant negative association of difficulty in identifying and describing feelings with quality of attachment to parents and peers. Further findings highlighted that difficulty in identifying and describing feelings significantly mediated the effect of quality of attachment (parent and peer) on NSSI and suicidal ideation. Conclusion: The ability to identify and describing feelings is important to managing emotional expression and understanding the feelings of others, both crucial in attaining successful interpersonal relationships. Our data revealed that, while controlling for stressful life events, low levels of attachment may increase adolescents' difficulty in identifying and describing their own feelings, which in turn may increase the risk of both NSSI and suicidal ideation.
Decomposing the Components of Friendship and Friends’ Influence on Adolescent Drinking and Smoking
Fujimoto, Kayo; Valente, Thomas W
2012-01-01
Purpose Friendship networks are an important source of peer influence. However, existing network studies vary in terms of how they operationalize friendship and friend’s influence on adolescent substance use. This study uses social network analysis to characterize three types of friendship relations: (1) mutual or reciprocated, (2) directional, and (3) intimate friends. We then examine the relative effects of each friendship type on adolescent drinking and smoking behavior. Methods Using a saturated sample from the Add Health data, a nationally representative sample of high-school adolescents (N=2,533 nested in 12 schools), we computed the level of exposure to drinking and smoking of friends using a network exposure model, and their association with individual drinking and smoking using fixed effect models. Results Results indicated that the influence from (1) is stronger on adolescent substance use than (2), especially for smoking. Regarding the directionality of (2), adolescents are equally influenced by both nominating and nominated friends on their drinking and smoking behavior. Results for (3) indicated that the influence from “best friends” was weaker than the one from non-“best friends,” which indicates that the order of friend nomination may not matter as much as nomination reciprocation. Conclusions This study demonstrates that considering different features of friendship relationships is important in evaluating friends’ influence on adolescent substance use. Related policy implications are discussed. PMID:22824443

This study examined the influence of single peer to peer interventions on participants' recovery attitudes. Following a 40-hour training, pairs of individuals with a psychiatric disability offered a session (2.5 hour) in outpatient and residential psychiatric institutions. These peer to peer interventions aimed at inspiring and contributing to participants' recovery process, by introducing them to constituent parts of the concept Recovery. Thirteen of the peer interventions were evaluated by measuring participants' recovery attitudes before (N = 145), just after (N = 115) and at 6 months postintervention (N = 53) using the Recovery Attitudes Questionnaire (RAQ7) and the Recovery Process Inventory (RPI). Wilcoxon tests demonstrated that individuals participating in a peer intervention felt significantly more certain that Recovery is possible (factor 'Recovery is possible') just after the intervention (p = 0.004), but not 6 months later; likewise, the perception of the difficulty of recovery in spite of a mental illness (factor 'Recovery is difficult and differs') was significantly lower 6 months later (p = 0.016), but not from pre to just after. The statistically significant effect of a single recovery-oriented peer intervention on participants' attitude that recovery is possible was not sustainable. These results suggest a possible higher sustainability of repeated or longer-lasting peer interventions. © 2012 The Authors.

A Survival Analysis of Adolescent Friendships: The Downside of Dissimilarity
Hartl, Amy C.; Laursen, Brett; Cillessen, Antonius H. N.
2015-01-01
The present study examined whether adolescent friendships dissolve because of characteristics of friends, differences between friends, or both. Participants included 410 adolescents (201 boys, 209 girls) who reported a total of 573 reciprocated friendships that originated in the 7th grade (M age = 13.20 years). Discrete-time survival analyses were conducted in which peer nominations and teacher ratings collected in Grade 7 predicted the occurrence and timing of friendship dissolution across grades 8 to 12. Grade 7 individual characteristics were unrelated to friendship stability, but Grade 7 differences in sex, peer acceptance, physical aggression, and school competence predicted subsequent friendship dissolution. The findings suggest that compatibility is a function of similarity between friends rather than the presence or absence of a particular trait. PMID:26187246

Following theories that individual differences in respiratory sinus arrhythmia (RSA) denote differential sensitivity to environmental influences, this study examines whether differences in RSA reactivity to specific emotional challenges predict differential response to intervention. We present data from a randomized clinical trial of a targeted intervention for early onset aggression. In collaboration with a high-risk urban school district, 207 kindergarten children (73% African American, 66% male), identified by their teachers as having high levels of aggressive and disruptive behavior, were recruited. All children received a universal social-emotional curriculum. One hundred children were randomly assigned to an additional intervention consisting of weekly peer-based social skills training. Complete RSA data were available for 139 of the children. Teacher-reported externalizing symptoms and emotion regulation in 1st grade (post intervention) were examined controlling for baseline levels. First-grade peer nominations of aggressive behavior, controlling for baseline nominations, were also examined as outcomes. No effect of resting RSA was found. However, greater reactivity to anger was associated with higher externalizing symptoms and lower emotion regulation skills in 1st grade relative to low reactive children. Lower reactivity to fear was associated with greater improvement over time, an effect that was enhanced in the targeted intervention condition. Results suggest that measures of affective reactivity may provide insight into children's capacity to benefit from different types of interventions.

Objective: The aim of this research was to obtain the views of young children regarding their reasons for rejecting a peer. Method: To achieve this goal, we conducted a qualitative study in the context of theory building research using an analysis methodology based on Grounded Theory. The collected information was extracted through semi-structured individual interviews from a sample of 853 children aged 6 from 13 urban public schools in Spain. Results: The children provided 3,009 rejection nominations and 2,934 reasons for disliking the rejected peers. Seven reason categories emerged from the analysis. Four categories refer to behaviors of the rejected children that have a cost for individual peers or peer group such as: direct aggression, disturbance of wellbeing, problematic social and school behaviors and dominance behaviors. A further two categories refer to the identities arising from the preferences and choices of rejected and rejecter children and their peers: personal identity expressed through preferences and disliking, and social identity expressed through outgroup prejudices. The “no-behavior or no-choice” reasons were covered by one category, unfamiliarity. In addition, three context categories were found indicating the participants (interpersonal–group), the impact (low–high), and the subjectivity (subjective–objective) of the reason. Conclusion: This study provides researchers and practitioners with a comprehensive taxonomy of reasons for rejection that contributes to enrich the theoretical knowledge and improve interventions for preventing and reducing peer rejection.

The Inventory of Callous-Unemotional Traits is a self- and other report questionnaire of callous-unemotional behaviors that is increasingly widely used in research and clinical settings. Nonetheless, questions about the factor structure and validity of scales remain. This study provided the first large-scale (N = 1,078) investigation of the parent report version of the Inventory of Callous-Unemotional Traits in a community sample of school-age (first-grade) children. Confirmatory factor analysis indicated that a two-factor model that distinguished empathic-prosocial (EP) from callous-unemotional (CU) behaviors provided the best fit to the data. EP and CU were moderately to strongly correlated with each other (ϕ = -.67, p < .001) and with oppositional defiant disorder and conduct disorder (ODD/CD) behaviors (ϕODD/CD, EP = -.55; ϕODD/CD, CU = .71, ps < .001). Individual differences in EP and CU behaviors explained unique variation, beyond that attributable to ODD/CD behaviors, in peer-, teacher-, and parent relationship quality. Moreover, whereas EP moderated the effects of ODD/CD in the prediction of student-teacher relationship quality, CU moderated the effects of ODD/CD in the prediction of peer and parent relationship quality. Results are discussed with respect to the use of the ICU with school-age children. © The Author(s) 2014.

Seeking to reduce problematic peer influence is a prominent theme of programs to prevent adolescent problem behavior. To support the refinement of this aspect of prevention programming, we examined peer influence and selection processes for three problem behaviors (delinquency, alcohol use, and smoking). We assessed not only the overall strengths of these peer processes, but also their consistency versus variability across settings. We used dynamic stochastic actor-based models to analyze five waves of friendship network data across sixth through ninth grades for a large sample of U.S. adolescents. Our sample included two successive grade cohorts of youth in 26 school districts participating in the PROSPER study, yielding 51 longitudinal social networks based on respondents' friendship nominations. For all three self-reported antisocial behaviors, we found evidence of both peer influence and selection processes tied to antisocial behavior. There was little reliable variance in these processes across the networks, suggesting that the statistical imprecision of the peer influence and selection estimates in previous studies likely accounts for inconsistencies in results. Adolescent friendship networks play a strong role in shaping problem behavior, but problem behaviors also inform friendship choices. In addition to preferring friends with similar levels of problem behavior, adolescents tend to choose friends who engage in problem behaviors, thus creating broader diffusion.

Objective To pilot test a peer support intervention, involving peer delivery of pain self-management strategies, for veterans with chronic musculoskeletal pain. Design Pre-test/post-test with 4-month intervention period. Methods Ten peer coaches were each assigned 2 patients (n=20 patients). All had chronic musculoskeletal pain. Guided by a study manual, peer coach-patient pairs were instructed to talk bi-weekly for 4 months. Pain was the primary outcome and was assessed with the PEG, a 3-item version of the Brief Pain Inventory, and the PROMIS Pain Interference Questionnaire. Several secondary outcomes were also assessed. To assess change in outcomes, a linear mixed model with a random effect for peer coaches was applied. Results Nine peer coaches and 17 patients completed the study. All were male veterans. Patients’ pain improved at 4 months compared to baseline but did not reach statistical significance (PEG: p = .33, ICC [intra-class correlation] = .28, Cohen's d = −.25; PROMIS: p = .17, d = −.35). Of secondary outcomes, self-efficacy (p = .16, ICC = .56, d = .60) and pain centrality (p = .06, ICC = .32, d = −.62) showed greatest improvement, with moderate effect sizes. Conclusions This study suggests that peers can effectively deliver pain self-management strategies to other veterans with pain. Although this was a pilot study with a relatively short intervention period, patients improved on several outcomes. PMID:25312858

The purpose of this study was to examine the educational impact of an intervention, the inquiry-focused textbook Integrating Concepts in Biology ( ICB ), when used in a yearlong introductory biology course sequence. Student learning was evaluated using three published instruments: 1) The Biology Concept Inventory probed depth of student mastery of fundamental concepts in organismal and cellular topics when confronting misconceptions as distractors. ICB students had higher gains in all six topic categories (+43% vs. peers overall, p < 0.01). 2) The Biology Card Sorting Task assessed whether students organized biological ideas more superficially, as novices do, or based on deeper concepts, like experts. The frequency with which ICB students connected deep-concept pairs, or triplets, was similar to peers; but deep understanding of structure/function was much higher (for pairs: 77% vs. 25%, p < 0.01). 3) A content-focused Medical College Admission Test (MCAT) posttest compared ICB student content knowledge with that of peers from 15 prior years. Historically, MCAT performance for each semester ranged from 53% to 64%; the ICB cohort scored 62%, in the top quintile. Longitudinal tracking in five upper-level science courses the following year found ICB students outperformed peers in physiology (85% vs. 80%, p < 0.01). © 2017 D. B. Luckie et al.

This study examined contextually-inappropriate (CI) anger in relation to emotion recognition and situation knowledge, negative social experiences, and externalizing behavior among low-income 4-year-olds attending Head Start (n=134). Approximately one-quarter of children (23%) showed anger when presented with positive/neutral slides and videos (valence-incongruent CI anger), whereas 2/5 of children (40%) showed anger when presented with negative slides and videos (valence-congruent CI anger). Valence-incongruent CI anger was associated with lower emotion situation knowledge (for boys only), more self-reported peer rejection and loneliness, and greater negative nominations by teachers and peers. Both valence-incongruent and (for boys only) valence-congruent CI anger were positively associated with externalizing behavior. Overall, valence-incongruent CI anger was more strongly associated with negative child outcomes than valence-congruent CI anger. PMID:26376288
Decomposing the components of friendship and friends' influence on adolescent drinking and smoking.
Fujimoto, Kayo; Valente, Thomas W
2012-08-01
Friendship networks are an important source of peer influence. However, existing network studies vary in terms of how they operationalize friendship and friend's influence on adolescent substance use. This study uses social network analysis to characterize three types of friendship relations: (1) mutual or reciprocated, (2) directional, and (3) intimate friends. We then examine the relative effects of each friendship type on adolescent drinking and smoking behavior. Using a saturated sample from the Add Health data, a nationally representative sample of high school adolescents (N = 2,533 nested in 12 schools), we computed the level of exposure to drinking and smoking of friends using a network exposure model, and their association with individual drinking and smoking using fixed effect models. Results indicated that the influence from mutual or reciprocated type of friendship relations is stronger on adolescent substance use than directional, especially for smoking. Regarding the directionality of directional type of friendship relations, adolescents are equally influenced by both nominating and nominated friends on their drinking and smoking behavior. Results for intimate friends friendship relations indicated that the influence from "best friends" was weaker than the one from non-"best friends," which indicates that the order of friend nomination may not matter as much as nomination reciprocation. This study demonstrates that considering different features of friendship relationships is important in evaluating friends' influence on adolescent substance use. Related policy implications are discussed. Copyright © 2012 Society for Adolescent Health and Medicine. Published by Elsevier Inc. All rights reserved.
Associations of group level popularity with observed behavior and influence in a dyadic context.
Lansu, Tessa A M; Cillessen, Antonius H N

This study examined the association between popularity in the peer group and adolescents' behavior in a dyadic context. After collecting peer nominations for popularity, 218 early adolescents (M(age) = 11.0 years) in 109 randomly composed same-sex dyads participated in a discussion task where they planned a party for their classroom. From digital recordings of the sessions, each participant's influence, involvement, skillful leadership, coercive resource control, submissiveness, positivity, and negativity were observed. Analyses with the actor-partner interdependence model (APIM) demonstrated that for girls high group level popularity was associated with a socially sensitive interaction style and influence in the dyadic context. For both boys and girls, the interaction partner's group level popularity negatively predicted their use of coercive resource control strategies and negative behavior in the dyad. For girls, in addition, the interaction partner's group level popularity also positively predicted their submissiveness and negatively predicted their task influence. These results indicate that, in particular for girls, adolescents' group level popularity plays an important role in the behavior of both peers in a cooperative dyadic context.

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 developmental trajectories in peer-reported aggressive behavior across the transition from elementary-to-middle school, and whether aggressive behavior trajectories were associated with friendship quality, friends' aggressive behavior, and the ways in which children think about their friendships. Participants included a community sample of 230 5 th grade children who were assessed when they made a transition from elementary-to-middle school (6 th grade). Peer nominations were used to assess the target child's and friend's aggressive behavior. Self- and friend reports were used to measure friendship quality; friendship understanding was assessed via a structured interview. General Growth Mixture Modeling (GGMM) revealed three distinct trajectories of peer-reported aggressive behavior across the school transition: low-stable, decreasing, and increasing. Adolescents' understanding of friendship formation differentiated the decreasing from the low-stable aggressive behavior trajectories, and the understanding of friendship trust differentiated the increasing from the low-stable aggressive and decreasing aggressive behavior trajectories. The findings indicated that a sophisticated understanding of friendship may serve as a protective factor for initially aggressive adolescents as they transition into middle school. Promoting a deepened understanding of friendship relations and their role in one's own and others' well-being may serve as an important prevention and intervention strategy to reduce aggressive behavior.

Adolescents interact with their peers in multiple social settings and form various types of peer relationships that affect drinking behavior. Friendship and popularity perceptions constitute critical relationships during adolescence. These two relations are commonly measured by asking students to name their friends, and this network is used to construct drinking exposure and peer status variables. This study takes a multiplex network approach by examining the congruity between friendships and popularity as correlates of adolescent drinking. Using data on friendship and popularity nominations among high school adolescents in Los Angeles, California (N = 1707; five schools), we examined the associations between an adolescent's drinking and drinking by (a) their friends only; (b) multiplexed friendships, friends also perceived as popular; and (c) congruent, multiplexed-friends, close friends perceived as popular. Logistic regression results indicated that friend-only drinking, but not multiplexed-friend drinking, was significantly associated with self-drinking (AOR = 3.51, p < 0.05). However, congruent, multiplexed-friend drinking also was associated with self-drinking (AOR = 3.10, p < 0.05). This study provides insight into how adolescent health behavior is predicated on the multiplexed nature of peer relationships. The results have implications for the design of health promotion interventions for adolescent drinking. Copyright © 2014 The Authors. Published by Elsevier Ltd.. All rights reserved.

Update to An Inventory of Sources and Environmental ...
In 2006, EPA published an inventory of sources and environmental releases of dioxin-like compounds in the United States. This draft report presents an update and revision to that dioxin source inventory. It also presents updated estimates of environmental releases of dioxin-like compounds to the air, water, land and products. The sources are grouped into five broad categories: combustion sources, metals smelting/refining, chemical manufacturing, natural sources, and environmental reservoirs. Estimates of annual releases to land, air, and water are presented for reference years 1987, 1995, and 2000. While the overall decreasing trend in emissions seen in the original report continues, the individual dioxin releases in this draft updated report are generally higher than the values reported in 2006. This is largely due to the inclusion (in all three years) of additional sources in the quantitative inventory that were not included in the 2006 report. The largest new source included in this draft updated inventory was forest fires. In the 2006 report, this was classified as preliminary and not included in the quantitative inventory. The top three air sources of dioxin emissions in 2000 were forest fires, backyard burning of trash, and medical waste incinerators. The Report Presents An Update To The Dioxin Source Inventory Published In 2006 (U.S. Epa, 2006). The Peer-Review Panel For The 2006 Document Provided Additional Comments After The Final Report Had

As a condition to the Department of Energy (DOE) Low Level Waste Disposal Federal Facility Review Group (LFRG) review team approving the Savannah River Site (SRS) Composite Analysis (CA), SRS agreed to follow up on a secondary issue, which consisted of the consolidation of several observations that the team concluded, when evaluated collectively, could potentially impact the integration of the CA results. This report addresses secondary issue observations 4 and 21, which identify the need to improve the CA sensitivity and uncertainty analysis specifically by improving the CA inventory and the estimate of its uncertainty. The purpose of the workmore » described herein was to be responsive to these secondary issue observations by re-examining the radionuclide inventories of the Integrator Operable Units (IOUs), as documented in ERD 2001 and Hiergesell, et. al. 2008. The LFRG concern has been partially addressed already for the Lower Three Runs (LTR) IOU (Hiergesell and Phifer, 2012). The work described in this investigation is a continuation of the effort to address the LFRG concerns by re-examining the radionuclide inventories associated with Fourmile Branch (FMB) IOU, Pen Branch (PB) IOU and Steel Creek (SC) IOU. The overall approach to computing radionuclide inventories for each of the IOUs involved the following components: • Defining contaminated reaches of sediments along the IOU waterways • Identifying separate segments within each IOU waterway to evaluate individually • Computing the volume and mass of contaminated soil associated with each segment, or “compartment” • Obtaining the available and appropriate Sediment and Sediment/Soil analytical results associated with each IOU • Standardizing all radionuclide activity by decay-correcting all sample analytical results from sample date to the current point in time, • Computing representative concentrations for all radionuclides associated with each compartment in each of the IOUs • Computing the radionuclide inventory of each DOE-added radionuclide for the compartments of each IOU by applying the representative, central value concentration to the mass of contaminated soil • Totaling the inventory for all compartments associated with each of the IOUs Using this approach the 2013 radionuclide inventories for each sub-compartment associated with each of the three IOUs were computed, by radionuclide. The inventories from all IOU compartments were then rolled-up into a total inventory for each IOU. To put the computed estimate of radionuclide activities within FMB, PB, and SC IOUs into context, attention was drawn to Cs-137, which was the radionuclide with the largest contributor to the calculated dose to a member of the public at the perimeter of SRS within the 2010 SRS CA (SRNL 2010). The total Cs-137 activity in each of the IOUs was calculated to be 9.13, 1.5, and 17.4 Ci for FMB, PB, and SC IOUs, respectively. Another objective of this investigation was to address the degree of uncertainty associated with the estimated residual radionuclide activity that is calculated for the FMB, PB, and SC IOUs. Two primary contributing factors to overall uncertainty of inventory estimates were identified and evaluated. The first related to the computation of the mass of contaminated material in a particular IOU compartment and the second to the uncertainty associated with analytical counting errors. The error ranges for the mass of contaminated material in each IOU compartment were all calculated to be approximately +/- 9.6%, or a nominal +/-10%. This nominal value was added to the uncertainty associated with the analytical counting errors that were associated with each radionuclide, individually. This total uncertainty was then used to calculate a maximum and minimum estimated radionuclide inventories for each IOU.« less

Attachment and self-evaluation in Chinese adolescents: age and gender differences.
Song, Hairong; Thompson, Ross A; Ferrer, Emilio
2009-10-01
This study investigated age and gender differences in the quality of attachment to mothers, fathers, and peers, and the association of attachment with measures of self-evaluation in 584 Chinese adolescents in junior high, high school, and university. Their responses to the Inventory of Parent and Peer Attachment indexed attachment quality, and self-evaluation was measured by the Rosenberg Self-Esteem Scale and the Self-Liking and Self-Competence Scale. Consistent with findings with Western samples, our analyses revealed (a) lower parent-child relationship quality in middle (compared to early) adolescence, (b) a significant association of parental and peer attachment with self-evaluation, and (c) gender differences in attachment to peers, with females reporting stronger attachment than males. Chinese females reported stronger maternal attachment than did males, and for females the quality of maternal attachment was more strongly related to self-evaluation than any other attachment relationship. During high school, peer attachment quality - rather than parental - was preeminently associated with self-evaluation. The findings of this study indicate that in a context of considerable consistency of findings with Western studies, parent-child attachment in Chinese adolescents is also influenced by culture-specific practices that influence parent-youth relationships and their meaning to the child.

The present study evaluated whether 3 indices of friendship adjustment (mutual friendship involvement, friendship stability, friendship quality) are important, but overlooked, moderators of the impact of anxious-withdrawal on trajectories of psychological maladjustment during early adolescence. Participants included 271 young adolescents (51% boys; M age = 11.83 years; 42% ethnic minority) who completed peer nomination and self-report measures at 3 waves in a longitudinal study. In line with hypotheses, growth curve analyses revealed that anxious-withdrawal predicted less negative psychological adjustment trajectories for friended young adolescents, albeit somewhat differently for boys and girls. Understanding the unique significance of friendships in the lives of anxious-withdrawn young adolescents could improve interventions as their friendships may be more successfully targeted than their group-level peer difficulties.

Objective Ethnic communities often serve as the primary source of emotional support for older immigrants. This study aims to identify individuals who are more likely to be nominated as emotional confidants by age peers in the ethnic community and to examine factors contributing to the likelihood of being a more frequently endorsed confidant. Method Data were drawn from a survey with 675 older Korean Americans. Using the name-generator approach in Social Network Analysis (SNA), participants were asked to list the names of three emotional confidants among age peers in the community. Results A higher level of popularity (i.e., in-degree centrality) was predicted by male gender, advanced education, lower functional disability, fewer symptoms of depression, and higher levels of participation in social activities. Discussion: Our findings suggest the value of SNA as a means of identifying the key emotional confidants in the community and utilizing them in community-based interventions. PMID:26082133
Meta-analysis and Harmonization of Life Cycle Assessment Studies for Algae Biofuels.
Tu, Qingshi; Eckelman, Matthew; Zimmerman, Julie
2017-09-05
Algae biodiesel (BioD) and renewable diesel (RD) have been recognized as potential solutions to mitigating fossil-fuel consumption and the associated environmental issues. Life cycle assessment (LCA) has been used by many researchers to evaluate the potential environmental impacts of these algae-derived fuels, yielding a wide range of results and, in some cases, even differing on indicating whether these fuels are preferred to petroleum-derived fuels or not. This meta-analysis reviews the methodological preferences and results for energy consumption, greenhouse gas emissions, and water consumption for 54 LCA studies that considered algae BioD and RD. The significant variation in reported results can be primarily attributed to the difference in scope, assumptions, and data sources. To minimize the variation in life cycle inventory calculations, a harmonized inventory data set including both nominal and uncertainty data is calculated for each stage of the algae-derived fuel life cycle.

The objective of the present research was to develop an assessment model for children's social goals. The aims were (a) to fit children's social goals to a circumplex model and to examine links between goals and peer-reported social behaviors (aggression, withdrawal, and prosocial behavior) in a sample of 276 participants (134 girls, 11- to 12-year-olds) and (b) to replicate these findings and examine whether social behavior mediates the relationship between goals and sociometric status in an independent cross-validation sample of 310 participants (143 girls, 11- to 13-year-olds). Results showed a satisfactory fit to the circumplex model and adequate psychometric properties of the goal scales of the new measure, the Interpersonal Goals Inventory for Children. Other findings included significant and meaningful relations between goals and peer-reported behavior. Social behavior mediated the relations between goals and sociometric status.

The aim of this study was to explore the relationship between peer pressure and the health risk behaviors of secondary school students. Cross-sectional study using a self-completed questionnaire. Secondary school students in Year 3 were the target population of this study. Information was solicited from students on their perceptions of peer pressure using a questionnaire employing the Peer Pressure Inventory and their involvement in risk behaviors using a modified global school-based student health survey. A total of 840 secondary students from Hong Kong completed the questionnaires. The prevalence of secondary students who had ever smoked was 6.4%, consumed alcohol 39.2%, ever used drugs 0.5%, were sexually active 3.9%, and involved in bullying 20.5%. A higher proportion of secondary students involved in risk behaviors were affiliated with peers who were involved in the same activities: smoking (48.9%), drinking alcohol (86.5%), using drugs (18.2%), engaged in sexual activity (34.5%), and bullying (82.6%). The perception of peer conformity and peer involvement was found to be significantly correlated with the students' health risk behaviors, particularly with regard to smoking, drinking alcohol, and bullying. A logistic regression analysis showed that having friends who are involved in the same risk behaviors is the single most important factor associated with the participation of secondary students in those specific risk behaviors. The results of this study provided a better understanding of the association between peer pressure and the adoption of health behaviors. The development of effective peer-led prevention programs to reduce the uptake of health risk behaviors should therefore be promoted to prevent adolescents from developing serious health problems.

Engagement with peer review and self-assessment is not always regarded by student nurses as an activity that results in a positive learning experience. Literature indicates that withdrawal from the learning process becomes attractive to individuals affected by a negative experience of peer review. Literature also provides examples of student nurses' feeling 'torn to shreds' during the process of peer review, resulting in loss of confidence and self-esteem. An influencing factor in such situations appears to be the absence of specific learner-driven criteria against which student nurses can assess peer and self-performance. The idea was thus ignited, that creation and utilisation of a learner-driven feedback form might potentially prevent, or at least minimise, the possibility of negative peer review experience. Set within the context of a pre-registration nursing programme, within a Higher Education institution, student nurses (n=25), created a peer review/self-assessment feedback form. Its potential cross-discipline, global applicability is reasonably speculated. Purposive sampling, followed by Stratified Random sampling, maximised participant variation. Data collection took place on 34 occasions, utilising focus group discussions using Nominal Group Technique, a practical task which was video recorded for mediating artefact purposes, and individual interviews. Analysis was concept and theme driven. The study found that participants desired a new feedback form that specifically asks the evaluator to judge human qualities, such as 'compassion' and 'kindness', in addition to the skills and knowledge criteria that any peer review or self-assessment form used currently had incorporated. Providing the participants with the opportunity to develop criteria, against which performance could be measured, with emphasis being afforded to student inclusivity and resultant shift in power balance from the educator to the learner, embraces the idea of teaching and learning in the 21st Century.

This study examined changes in cultural perceptions and communication of 47 occupational therapy students and 39 international graduate students following 5 peer teaching activities. The peer-teaching activities were designed on the premise that positive contact between people of equal status improves intercultural competency, and included social exchanges, interviews, feedback on practice teaching, and role-playing. Changes in intercultural competency were measured with pre- and post administration of the Cross Cultural Adaptability Inventory (CCAI), as well as questionnaires and journals. Significant positive change between pre- and post-test scores on the CCAI (p<.0002) was found for the 86 participants. When stratified into 3 subgroups (international students and occupational therapy students with and without international travel experience), changes were more pronounced. Occupational therapy students with international travel experience benefited the most from the peer-teaching activities (p<.002) and international graduate students benefited as well (p<.009). Occupational therapy students without international travel experienced no significant change. The findings indicate that peer teaching activities significantly impacted cross-cultural communication for students with prior international travel experience and confirm the importance of contextual learning.

This study aimed to investigate the effect of self-transcendence on the physical health of multiple sclerosis (MS) patients attending peer support groups. This study was a quasi-experimental before-and-after design including 33 MS patients in three groups: 10 men in the men-only group, 11 women in the women-only group, and 12 men and women in the mixed group. Participants were required to attend eight weekly sessions of 2 h each. Instruments included the physical health section of the Multiple Sclerosis Quality of Life Inventory and Reed's Self-Transcendence Scale. Peer support group attendance was found to have a significant positive effect on the physical health and self-transcendence of MS patients when comparing average scores before and after attendance. Regression analysis showed that improvement in self-transcendence predicted improvement in physical health. Results show the positive effects of peer support groups on self-transcendence and physical health in MS patients, and suggest that improvement in well-being can be gained by promoting self-transcendence and physical health. © 2015 Wiley Publishing Asia Pty Ltd.

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.

A standardized method of measurement of self-care ability in children with obstetric brachial plexus palsy (OBPP) has not been universally adopted. A study was conducted to determine if the Pediatric Evaluation of Disability Inventory (PEDI) was able to discriminate between the self-care ability of children with OBPP and their peers and distinguish between those with differing severities of OBPP. The PEDI self-care domain results for 45 children with OBPP (30 without hand impairment, 15 with hand impairment) were reviewed retrospectively. The group performance of children without hand impairment was within 1 SD above the mean. The group performance of children with hand impairment was more than 2 SDs below the mean. The difference between the 2 groups was statistically significant. In this study children without hand impairment did not have a self-care activity limitation as measured by the PEDI. A deficit in self-care ability was found in those with hand impairment. The PEDI was able to differentiate between the performances of reported self-care activities of children with differing severities of OBPP; however, it was unable to discriminate between those without hand impairment and their peers.

Previous research has investigated caregiver attachment relationships in children with autism during early childhood, with few differences found from matched control groups. However, little is known of this relationship during middle childhood (ages 8-12 years). In this study, the aim was to establish whether there are differences in the security of attachment in children with high-functioning autism compared to typically developing children. A secondary aim was to establish whether caregivers' perceptions of their child's attachment to them accorded with the children's own reports. Twenty-one children with high-functioning autism and 17 typically developing children were administered the Kerns Security Scale and the Inventory of Parent and Peer Attachment-Revised, and caregivers completed the same questionnaires from the viewpoint of their child. There were no differences between the groups in the children's and parents' reports of attachment security. Parents' and children's reports were moderately correlated on the Kerns Security Scale but were not correlated on the Inventory of Parent and Peer Attachment-Revised. The results indicate that levels of attachment security in children with high-functioning autism are not different from those in typically developing children. © The Author(s) 2013.

Objective To investigate developmental trajectories in peer-reported aggressive behavior across the transition from elementary-to-middle school, and whether aggressive behavior trajectories were associated with friendship quality, friends’ aggressive behavior, and the ways in which children think about their friendships. Method Participants included a community sample of 230 5th grade children who were assessed when they made a transition from elementary-to-middle school (6th grade). Peer nominations were used to assess the target child’s and friend’s aggressive behavior. Self- and friend reports were used to measure friendship quality; friendship understanding was assessed via a structured interview. Results General Growth Mixture Modeling (GGMM) revealed three distinct trajectories of peer-reported aggressive behavior across the school transition: low-stable, decreasing, and increasing. Adolescents’ understanding of friendship formation differentiated the decreasing from the low-stable aggressive behavior trajectories, and the understanding of friendship trust differentiated the increasing from the low-stable aggressive and decreasing aggressive behavior trajectories. Conclusions The findings indicated that a sophisticated understanding of friendship may serve as a protective factor for initially aggressive adolescents as they transition into middle school. Promoting a deepened understanding of friendship relations and their role in one’s own and others’ well-being may serve as an important prevention and intervention strategy to reduce aggressive behavior.

Depressive symptoms are considered to have evolutionary social functions to reduce social risks with peers and family members. However, social processes and their relationship to depressive symptoms have been understudied in adolescent boys. Low engagement in social contexts may predict depressive symptoms in adolescent boys, as it may signify efforts to reduce social risks. To address these issues, this study focused on 160 boys at risk for affective problems based on low socioeconomic status. We evaluated how behavioral and physiological engagement in peer and family contexts, respectively, in late childhood predicted depressive symptoms at age 12 and age 15. Social withdrawal was measured across late childhood (ages 9 to 12) in a camp setting using a latent variable of the teacher ratings of withdrawn behavior, peer nominations of withdrawn behavior, and camp counselor ratings of withdrawn behavior. Physiological reactivity was measured during a provocative parent-child conversation using respiratory sinus arrhythmia (RSA) at age 12. Social withdrawal in late childhood predicted depressive symptoms at age 12. The combination of high levels of social withdrawal with peers from ages 9 to 12 and low RSA reactivity with a parent at age 12 predicted higher depressive symptoms at age 15. Withdrawal in multiple social contexts may place boys at risk for depressive symptoms during the vulnerable period of adolescence. PMID:22976840

Research of inmate social order is a once-vibrant area that receded just as American incarceration rates climbed and the country's carceral contexts dramatically changed. This study reengages inmate society with an abductive mixed methods investigation of informal status within a contemporary men's prison unit. The authors collect narrative and social network data from 133 male inmates housed in a unit of a Pennsylvania medium-security prison. Analyses of inmate narratives suggest that unit "old heads" provide collective goods in the form of mentoring and role modeling that foster a positive and stable peer environment. This hypothesis is then tested with Exponential Random Graph Models (ERGMs) of peer nomination data. The ERGM results complement the qualitative analysis and suggest that older inmates and those who have been on the unit longer are perceived by their peers as powerful and influential. Both analytical strategies point to the maturity of aging and the acquisition of local knowledge as important for attaining informal status in the unit. In sum, this mixed methods case study extends theoretical insights of classic prison ethnographies, adds quantifiable results capable of future replication, and points to a growing population of older inmates as important for contemporary prison social organization.

Although several social network studies have demonstrated peer influence effects on adolescent substance use, findings for marijuana use have been equivocal. This study examines whether structural features of friendships moderate friends' influence on adolescent marijuana use over time. Using 1-year longitudinal data from the National Longitudinal Study of Adolescent Health, this article examines whether three structural features of friendships moderate friends' influence on adolescent marijuana use: whether the friendship is reciprocated, the popularity of the nominated friend, and the popularity/status difference between the nominated friend and the adolescent. The sample consists of students in grade 10/11 at wave I, who were in grade 11/12 at wave II, from two large schools with complete grade-based friendship network data (N = 1,612). In one school, friends' influence on marijuana use was more likely to occur within mutual, reciprocated friendships compared with nonreciprocated relationships. In the other school, friends' influence was stronger when the friends were relatively popular within the school setting or much more popular than the adolescents themselves. Friends' influence on youth marijuana use may play out in different ways, depending on the school context. In one school, influence occurred predominantly within reciprocated relationships that are likely characterized by closeness and trust, whereas in the other school adopting friends' drug use behaviors appeared to be a strategy to attain social status. Further research is needed to better understand the conditions under which structural features of friendships moderate friends' influence on adolescent marijuana use.

Are Latino adolescents' friendships an untapped resource for academic achievement or perhaps one of the reasons why these youth struggle academically? Using data from the National Longitudinal Study of Adolescent Health (N = 6782; 7th through 12th graders; 52.9 % female), we examined whether the process of Latino students' school belonging mediated the relationships between the context of friendships (i.e., friendship network indicators) and their academic outcomes (i.e., a context-process-outcomes model), and tested whether the process-context link varied by friends' characteristics (i.e., GPA and problem behavior; social capital). Moreover, we tested whether all relationships varied across the four largest Latino subgroups in the U.S. (i.e., Mexican, Central/South American, Puerto Rican, and Cuban). Our findings indicate that being nominated as a friend by peers and perceiving to have friends exerted both direct effects on school belonging in all but one of the Latino ethnic samples (i.e., Puerto Rican samples) and indirect effects on academic achievement in the full Latino, Mexican, and Central/South American samples. As such, school belonging was more likely to explain the links between academic achievement with nominations by peers as a friend and perceived friends than with having close-knit friendship groups. However, having a close-knit group of average or low-achieving friends predicted more school belonging for Mexican youth, but less school belonging for Cubans. Our findings suggest that friendships may be particularly beneficial for the school belonging process of highly marginalized groups in the U.S. (i.e., Mexican-origin).
A problem-solving approach to nutrition education with Filipino mothers.
Ticao, C J; Aboud, F E
1998-06-01
The study examined Filipino mothers' problem solving on issues related to child feeding, using a dyadic, peer-help approach. The participants were mothers of children under 6 yr of age from a village in the southern Philippines, where malnutrition among children is prevalent. Mothers were paired with a mutual friend (each nominated the other as a best friend) or a unilateral friend (only one nominated the other as a best friend) to discuss a feeding problem to which they initially gave similar solutions (agreed) and one to which they gave different solutions (disagreed). In the final step, they were asked to give privately the solutions they considered best for the problem. The number and quality of these final-step solutions were analyzed as a function of the friend relation, the level of initial agreement with their friend partner, and the source of the solution. Results indicated that the quantity and quality of solutions increased from before to after the dyadic discussion, especially among mothers paired with a mutual friend with whom they agreed. Most of their final-step solutions came from ones they themselves had generated during the discussion, not ones their friend partner had proposed. There was also evidence that high quality solutions were generated by mothers paired with a disagreeing unilateral friend. Implications for nutrition education concern the benefits of a peer-help, dyadic problem-solving approach, taking into account the role of a friend in facilitating a mother's production of new solutions to child feeding problems. The procedure may be used by health promoters who want to build capacities and self-reliance through collective problem solving.

Overweight is a potential risk factor for peer victimization in late childhood and adolescence. The current study investigated the association between BMI in early primary school and different bullying involvement roles (uninvolved, bully, victim, and bully-victim) as reported by teachers and children themselves. In a population-based study in the Netherlands, measured BMI and teacher-reported bullying behavior were available for 4364 children (mean age = 6.2 years). In a subsample of 1327 children, a peer nomination method was used to obtain child reports of bullying. In both teacher- and child-reported data, a higher BMI was associated with more victimization and more bullying perpetration. For instance, a 1-point increase in BMI was associated with a 0.05 increase on the standardized teacher-reported victimization score (95% confidence interval, 0.03 to 0.07; P < .001). Combining the victimization and bullying scores into different types of bullying involvement showed that children with obesity, but not children with overweight, had a significantly higher risk to be a bully-victim (odds ratio = 2.25; 95% confidence interval, 1.62 to 3.14) than normal-weight peers. At school entry, a high BMI is a risk factor associated with victimization and bullying perpetration, with obese children particularly likely to be victims and aggressors. Results were consistent for teacher and child reports of bullying, supporting the validity of our findings. Possibly, obesity triggers peer problems, but the association may also reflect a common underlying cause that makes obese children vulnerable to bullying involvement.

Postpartum depression peer support: maternal perceptions from a randomized controlled trial.
Dennis, Cindy-Lee
2010-05-01
Peer support in the early postpartum period is effective in the prevention of postpartum depression among women identified as high-risk. To describe maternal perceptions of peer support received while participating in a trial. Cross-sectional survey of women participating in a randomized controlled trial to evaluate the effect of peer support in the prevention of postpartum depression. Seven health regions across Ontario Canada. 701 women were recruited between November 2004 and September 2006. Women eligible for the study were all mothers with an Edinburgh Postnatal Depression Scale score >9 who were within 2 weeks postpartum, at least 18 years of age, able to speak English, had a live birth, and had been discharged home from the hospital. Exclusion criteria included an infant not discharged home with the mother and current use of antidepressant or antipsychotic medication. Two hundred and twenty-one mothers completed the mailed questionnaire. Women were randomly allocated to receive usual postpartum care (control group) or usual postpartum care plus telephone-based peer support (intervention group). Maternal perceptions of peer support were evaluated at 12 weeks postpartum using the validated Peer Support Evaluation Inventory. Interactions provided by the peer volunteer included the provision of emotional (92.7%), informational (72.4%), and appraisal (72.0%) support. Mothers reported high levels of positive relationship qualities such as trust (83.6%) and perceived acceptance (79.1%). Most (80.5%) mothers indicated they were very satisfied with their peer support experience. Maternal satisfaction was associated with the number and duration of peer volunteer contacts. The majority of mothers perceived their peer volunteer experience positively lending further support to telephone-based peer support as a preventative strategy for postpartum depression. The following program modifications were suggested: (a) adapt training to enhance the provision of appraisal support; (b) improve matching of volunteers to participants based on age, number of children, and breastfeeding status; and (c) ensure participating mothers want to receive peer support in order to facilitate the development of relationships with their assigned peers.

Global building inventory for earthquake loss estimation and risk management
Jaiswal, Kishor; Wald, David; Porter, Keith
2010-01-01
We develop a global database of building inventories using taxonomy of global building types for use in near-real-time post-earthquake loss estimation and pre-earthquake risk analysis, for the U.S. Geological Survey’s Prompt Assessment of Global Earthquakes for Response (PAGER) program. The database is available for public use, subject to peer review, scrutiny, and open enhancement. On a country-by-country level, it contains estimates of the distribution of building types categorized by material, lateral force resisting system, and occupancy type (residential or nonresidential, urban or rural). The database draws on and harmonizes numerous sources: (1) UN statistics, (2) UN Habitat’s demographic and health survey (DHS) database, (3) national housing censuses, (4) the World Housing Encyclopedia and (5) other literature.

This paper discusses the application of Information Management Systems (IMS) for documenting and monitoring World Heritage (WH) properties. The application of IMS in WH can support all stakeholders involved in conservation, and management of cultural heritage by more easily inventorying, mining and exchanging information from multiple sources based on international standards. Moreover, IMS could assist in detecting damages and preparing management strategies to mitigate risks, and slowing down the deterioration of the integrity of WH properties. The case study of the Silk Roads Cultural Heritage Resource Information System (CHRIS), a Belgian Federal Science Policy Office funded project, illustrates the capabilities of IMS in the context of the nomination of the Central Asian Silk Roads on the WH List. This multi-lingual, web-based IMS will act as a collaborative platform allowing for the completion of improved transnational nomination dossiers and subsequent monitoring activities with all necessary baseline information to easily verify consistency and quality of the proposal. The Silk Roads CHRIS Geospatial Content Management System uses open source technologies and allows to georeference data from different scales and sources including data from field recording methods and combine it with historical and heritage features documented through various means such as textual descriptions, documents, photographs, 3D models or videos. Moreover, tailored maps can also be generated by overlaying a selection of available layers and then be exported to support the nomination dossier. Finally, by using this innovative information and decision support system, the State Parties and other interested stakeholders will have access to a complete nomination dossier and could therefore respond more effectively to hazards and disaster phenomena.

The aim of this study was to pilot test a peer support intervention, involving peer delivery of pain self-management strategies, for veterans with chronic musculoskeletal pain. Pretest/posttest with 4-month intervention period. Ten peer coaches were each assigned 2 patients (N = 20 patients). All had chronic musculoskeletal pain. Guided by a study manual, peer coach-patient pairs were instructed to talk biweekly for 4 months. Pain was the primary outcome and was assessed with the PEG, a three-item version of the Brief Pain Inventory, and the PROMIS Pain Interference Questionnaire. Several secondary outcomes were also assessed. To assess change in outcomes, a linear mixed model with a random effect for peer coaches was applied. Nine peer coaches and 17 patients completed the study. All were male veterans. Patients' pain improved at 4 months compared with baseline but did not reach statistical significance (PEG: P = 0.33, ICC [intra-class correlation] = 0.28, Cohen's d = -0.25; PROMIS: P = 0.17, d = -0.35). Of secondary outcomes, self-efficacy (P = 0.16, ICC = 0.56, d = 0.60) and pain centrality (P = 0.06, ICC = 0.32, d = -0.62) showed greatest improvement, with moderate effect sizes. This study suggests that peers can effectively deliver pain self-management strategies to other veterans with pain. Although this was a pilot study with a relatively short intervention period, patients improved on several outcomes. Published [2014].

Coronary angiography can be stressful for patients and anxiety-caused physiological responses during the procedure increase the risk of dysrhythmia, coronary artery spasms and rupture. This study therefore aimed to investigate the effects of peer, video and combined peer-and-video training on anxiety among patients undergoing coronary angiography. This single-blinded randomised controlled clinical trial was conducted at two large educational hospitals in Iran between April and July 2016. A total of 120 adult patients undergoing coronary angiography were recruited. Using a block randomisation method, participants were assigned to one of four groups, with those in the control group receiving no training and those in the three intervention groups receiving either peer-facilitated training, video-based training or a combination of both. A Persian-language validated version of the State-Trait Anxiety Inventory was used to measure pre- and post-intervention anxiety. There were no statistically significant differences in mean pre-intervention anxiety scores between the four groups (F = 0.31; P = 0.81). In contrast, there was a significant reduction in post-intervention anxiety among all three intervention groups compared to the control group (F = 27.71; P <0.01); however, there was no significant difference in anxiety level in terms of the type of intervention used. Peer, video and combined peer-and-video education were equally effective in reducing angiography-related patient anxiety. Such techniques are recommended to reduce anxiety amongst patients undergoing coronary angiography in hospitals in Iran.

To characterize the impact of widespread inventory management policies on stock-outs of essential drugs in Zambia's health clinics and develop related recommendations. Daily clinic storeroom stock levels of artemether-lumefantrine (AL) products in 2009-2010 were captured in 145 facilities through photography and manual transcription of paper forms, then used to determine historical stock-out levels and estimate demand patterns. Delivery lead-times and estimates of monthly facility accessibility were obtained through worker surveys. A simulation model was constructed and validated for predictive accuracy against historical stock-outs, then used to evaluate various changes potentially affecting product availability. While almost no stock-outs of AL products were observed during Q4 2009 consistent with primary analysis, up to 30% of surveyed facilities stocked out of some AL product during Q1 2010 despite ample inventory being simultaneously available at the national warehouse. Simulation experiments closely reproduced these results and linked them to the use of average past monthly issues and failure to capture lead-time variability in current inventory control policies. Several inventory policy enhancements currently recommended by USAID | DELIVER were found to have limited impact on product availability. Inventory control policies widely recommended and used for distributing medicines in sub-Saharan Africa directly account for a substantial fraction of stock-outs observed in common situations involving demand seasonality and facility access interruptions. Developing central capabilities in peripheral demand forecasting and inventory control is critical. More rigorous independent peer-reviewed research on pharmaceutical supply chain management in low-income countries is needed.

Bullies and power: a look at the research.
Carter, Susan
2011-01-01
Research indicates that bullying continues to plague schools, and school-based anti-bullying programs do little to take away the opportunities and power of the child who bullies. Research indicates methods to identify the child who bullies, and provides guidelines to change the bullying behaviors. Unfortunately, this information fails to result in changes in practice. Nomination of children who bully by their peers and the utilization of methods that remove the bully's power are promising interventions. Administrators, teachers, parents, nurses, and mental health providers need to be proactive in utilizing these interventions, and provide training for school staff.

Objective The increasing global health burden imposed by eating disorders warrants close examination of social exposures associated with globalization that potentially elevate risk during the critical developmental period of adolescence in low- and middle-income countries (LMICs). The study aim was to investigate the association of peer influence and perceived social norms with adolescent eating pathology in Fiji, a LMIC undergoing rapid social change. Method We measured peer influence on eating concerns (with the Inventory of Peer Influence on Eating Concerns; IPIEC), perceived peer norms associated with disordered eating and body concerns, perceived community cultural norms, and individual cultural orientations in a representative sample of school-going ethnic Fijian adolescent girls (n=523). We then developed a multivariable linear regression model to examine their relation to eating pathology (measured by the Eating Disorder Examination-Questionnaire; EDE-Q). Results We found independent and statistically significant associations between both IPIEC scores and our proxy for perceived social norms specific to disordered eating (both p <.001) and EDE-Q global scores in a fully adjusted linear regression model. Discussion Study findings support the possibility that peer influence as well as perceived social norms relevant to disordered eating may elevate risk for disordered eating in Fiji, during the critical developmental period of adolescence. Replication and extension of these research findings in other populations undergoing rapid social transition—and where globalization is also influencing local social norms—may enrich etiologic models and inform strategies to mitigate risk.

Children with poor emotion knowledge (EK) skills are at risk for externalizing problems; less is known about early internalizing behavior. We examined multiple facets of EK and social-emotional experiences relevant for internalizing difficulties, including loneliness, victimization, and peer rejection, in Head Start preschoolers (N = 134; M = 60 months). Results based on multiple informants suggest that facets of EK are differentially related to negative social-emotional experiences and internalizing behavior and that sex plays a moderating role. Behavioral EK was associated with self-reported loneliness, victimization/rejection, and parent-reported internalizing symptoms. Emotion recognition and expressive emotion knowledge were related to self-reported loneliness, and emotion situation knowledge was related to parent-reported internalizing symptoms and negative peer nominations. Sex moderated many of these associations, suggesting that EK may operate differently for girls versus boys in the preschool social context. Results are discussed with regard to the role of EK for social development and intervention implications. PMID:25859097
Main and moderated effects of moral cognition and status on bullying and defending.
Caravita, Simona C S; Gini, Gianluca; Pozzoli, Tiziana
2012-01-01
This study analyzed the relations of two dimensions of moral cognition (i.e., acceptance of moral transgression and moral disengagement) and two forms of status in the peer group (i.e., social preference and perceived popularity) with bullying and defending among 235 primary-school children and 305 middle-school early adolescents. Social status was tested as a moderator of the associations between moral cognition and bullying and defending. Participants completed self-reports assessing the two dimensions of moral cognition and peer nominations for status, bullying, and defending. Both acceptance of moral transgression and moral disengagement were associated to bullying among early adolescents only, whereas in childhood moral disengagement was linked to defending among girls. Social status moderated the associations between morality dimensions and bullying and defending. The moderating effects of status were discussed considering status as a magnifying lens for the relations between individual characteristics and social behavior. The results were also discussed with reference to age and gender differences in the associations. © 2012 Wiley Periodicals, Inc.

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.
Documentation and Cultural Heritage Inventories - Case of the Historic City of Ahmadabad

Located in the western Indian state of Gujarat, the historic city of Ahmadabad is renowned for the unparalleled richness of its monumental architecture, traditional house form, community based settlement patterns, city structure, crafts and mercantile culture. This paper describes the process followed for documentation and development of comprehensive Heritage Inventories for the historic city with an aim of illustrating the Outstanding Universal Values of its Architectural and Urban Heritage. The exercise undertaken between 2011 & 2014 as part of the preparation of world heritage nomination dossier included thorough archival research, field surveys, mapping and preparation of inventories using a combination of traditional data procurement and presentation tools as well as creation of advanced digital database using GIS. The major challenges encountered were: need to adapt documentation methodology and survey formats to field conditions, changing and ever widening scope of work, corresponding changes in time frame, management of large quantities of data generated during the process along with difficulties in correlating existing databases procured from the local authority in varying formats. While the end result satisfied the primary aim, the full potential of Heritage Inventory as a protection and management tool will only be realised after its acceptance as the statutory list and its integration within the larger urban development plan to guide conservation, development and management strategy for the city. The rather detailed description of evolution of documentation process and the complexities involved is presented to understand the relevance of methods used in Ahmadabad and guide similar future efforts in the field.

The purpose of this study was threefold: 1) to describe spiritual well-being (existential and religious well-being) in adolescents with inflammatory bowel disease (IBD) versus healthy peers; 2) to examine associations of spiritual well-being with mental health outcomes (emotional functioning and depressive symptoms); and 3) to assess the differential impact of existential versus religious well-being on mental health. A total of 155 adolescents aged 11-19 years from a children's hospital and a university hospital filled out questionnaires including the Spiritual Well-Being Scale, the Children's Depression Inventory-Short Form, and the Pediatric Quality of Life Inventory. Covariates in multivariable models included demographics, disease status, and interactions. Participants' mean (SD) age was 15.1 (2.0) years; 80 (52%) were male; and 121 (78%) were of white ethnicity. Levels of existential and religious well-being were similar between adolescents with IBD and healthy peers. In multivariable analyses, existential well-being was associated with mental health (partial R(2) change = .08-.11, p < .01) above and beyond other characteristics (total R(2) = .23, p < .01). Presence of disease moderated both the relationship between existential well-being and emotional functioning and that between religious well-being and depressive symptoms: that is, the relationships were stronger in adolescents with IBD as compared with healthy peers. Religious well-being was only marginally significantly associated with mental health after controlling for other factors. Although both healthy adolescents and those with IBD had high levels of spiritual well-being, having IBD moderated the relationship between spiritual well-being and mental health. Meaning/purpose was related to mental health more than was connectedness to the sacred.

To examine the efficacy of a peer-mentoring program for persons with traumatic brain injury (TBI) and their significant others, and to determine the relationship of this mentoring program to 3 main outcomes: (1) emotional well-being; (2) post-TBI quality of life; and (3) community integration. Randomized controlled trial. Midwestern rehabilitation hospital. Persons with TBI (n=96) and significant others/caregivers (n=62). Persons with TBI and friends/caregivers who knew the person prior to their injury were randomly assigned to a treatment (mentored) or no-treatment (no mentoring) control group immediately prior to discharge from the rehabilitation unit and were mentored for up to 2 years. Peer Mentoring Questionnaire; Brief Symptom Inventory-18; Family Assessment Device; Coping Inventory for Stressful Situations; Short Michigan Alcohol Screening Test; Medical Outcomes Study 12-Item Short-Form Health Survey; and Community Integration Measure. Eighty-eight percent of individuals who were involved in the mentoring program reported positive experiences. t tests revealed that among persons with TBI, individuals who received mentoring had significantly better behavioral control and less chaos in the living environment (P=.04), lower alcohol use (P=.01), less emotion-focused (P=.04) and avoidance coping (P=.03), and good physical quality of life (P=.04) compared with those who did not receive mentoring. Among significant others, mentored individuals demonstrated greater community integration (P=.03) than the nonmentored control group. Mentoring can be an effective way to benefit mood and healthy coping after TBI, and it can help to prevent maladaptive behaviors, such as substance abuse and behavioral dyscontrol, in the living situation.

The occurrence of stressful life events is a risk factor for psychopathology in adolescence. Depression is a problem of notable clinical importance that has a negative psychosocial impact on adolescents and which has considerable social, educational, and economic costs. The aim of this study was to examine the relationship between stressful life events and depressive symptomatology in adolescence, taking into account the effect that attachment representations may have on this relation. Participants were 1653 adolescents (951 girls) aged between 13 and 18 years. The sample was selected by means of a random sampling procedure based on the availability of schools to participate. Data were collected at two time points: attachment and stressful life events were assessed first, and symptoms of depression were evaluated eight to nine months later. Two time points were used in order to better analyze the mediating role of attachment security. Stressful life events were recorded using the Inventory of Stressful Life Events, attachment was evaluated by the Inventory of Parent and Peer Attachment (mother, father, and peer versions), and depressive symptomatology was assessed through the Children's Depression Scale. In all cases, the Basque version of these scales was used. The results indicated that attachment to parents was a mediating variable in the relationship between stressful life events and depressive symptomatology. Contrary to what we expected, the results indicate that stressful life events did not have a negative effect on peer attachment, and neither did the latter variable act as a mediator of the relationship between stressful life events and depressive symptoms. It can be concluded that attachment-based interventions may be especially useful for reducing depression symptoms among adolescents. The findings also suggest a role for interventions that target parent-child attachment relationships.

A popular explanation for race and ethnic disparities in academic achievement is that minorities are exposed to different peers and have different opportunities to make friends with high-achievers. Although we know that adolescents from different race and ethnic groups attend different schools and that they choose different friends, we do not know how these different opportunities affect the friends they make. This paper fills this gap by studying how the opportunities within adolescents’ schools affect race and ethnic differences in the academic characteristics of friends. Using data from the National Longitudinal Study of Adolescent Health and the conditional logit and opportunities framework, I account for adolescents’ different opportunities to make friends both within and across schools. Ignoring their different opportunities, Black and Latino adolescents’ nominated friends have significantly lower levels of achievement than white adolescents. After accounting for their different opportunities to make friends within and between schools, race and ethnic differences in the achievement characteristics of friends disappear. If Black and Latino adolescents’ opportunity structures were identical to white adolescents’, their probabilities of nominating high-achieving friends would not differ. PMID:23017858

This study examined differences in friendship quality between children with traumatic brain injury (TBI) and orthopedic injury (OI) and behavioral outcomes for children from both groups. Participants were 41 children with TBI and 43 children with OI (M age = 10.4). Data were collected using peer- and teacher-reported measures of participants’ social adjustment and parent-reported measures of children’s post-injury behaviors. Participants and their mutually nominated best friends also completed a measure of the quality of their friendships. Children with TBI reported significantly more support and satisfaction in their friendships than children with OI. Children with TBI and their mutual best friend were more similar in their reports of friendship quality compared to children with OI and their mutual best friends. Additionally, for children with TBI who were rejected by peers, friendship support buffered against maladaptive psychosocial outcomes, and predicted skills related to social competence. Friendship satisfaction was related to higher teacher ratings of social skills for the TBI group only. Positive and supportive friendships play an important role for children with TBI, especially for those not accepted by peers. Such friendships may protect children with TBI who are rejected against maladaptive psychosocial outcomes, and promote skills related to social competence. PMID:24840021
Where “Old Heads” Prevail: Inmate Hierarchy in a Men’s Prison Unit*

Research of inmate social order is a once-vibrant area that receded just as American incarceration rates climbed and the country’s carceral contexts dramatically changed. This study reengages inmate society with an abductive mixed methods investigation of informal status within a contemporary men’s prison unit. The authors collect narrative and social network data from 133 male inmates housed in a unit of a Pennsylvania medium-security prison. Analyses of inmate narratives suggest that unit “old heads” provide collective goods in the form of mentoring and role modeling that foster a positive and stable peer environment. This hypothesis is then tested with Exponential Random Graph Models (ERGMs) of peer nomination data. The ERGM results complement the qualitative analysis and suggest that older inmates and those who have been on the unit longer are perceived by their peers as powerful and influential. Both analytical strategies point to the maturity of aging and the acquisition of local knowledge as important for attaining informal status in the unit. In sum, this mixed methods case study extends theoretical insights of classic prison ethnographies, adds quantifiable results capable of future replication, and points to a growing population of older inmates as important for contemporary prison social organization.

Abstract Background Alacranes Reef was declared as a National Marine Park in 1994. Since then, many efforts have been made to inventory its biodiversity. However, groups such as amphipods have been underestimated or not considered when benthic invertebrates were inventoried. Here we present a dataset that contributes to the knowledge of benthic amphipods (Crustacea, Peracarida) from the inner lagoon habitats from the Alacranes Reef National Park, the largest coral reef ecosystem in the Gulf of Mexico. The dataset contains information on records collected from 2009 to 2011. Data are available through Global Biodiversity Information Facility (GBIF). New information A total of 110 amphipod species distributed in 93 nominal species and 17 generic species, belonging to 71 genera, 33 families and three suborders are presented here. This information represents the first online dataset of amphipods from the Alacranes Reef National Park. The biological material is currently deposited in the crustacean collection from the regional unit of the National Autonomous University of Mexico located at Sisal, Yucatan, Mexico (UAS-Sisal). The biological material includes 588 data records with a total abundance of 6,551 organisms. The species inventory represents, until now, the richest fauna of benthic amphipods registered from any discrete coral reef ecosystem in Mexico. PMID:29416428

Lunar sample-based volatile studies have focused on assessing the inventory and distribution of water in the Moon. Some have focused on the relatively young mare basalts and pyroclastic glasses, which result from partial melting of the relatively young lunar mantle. Less certain is the water inventory for the oldest materials available, which have the greater potential to record the earliest history of volatiles in the Moon (and thus provide evidence for the "wet" vs. "dry" accretion hypotheses of the Earth-Moon system. Studies of volatiles in ancient lunar rocks have largely focused on apatite. One recent FTIR (Fourier Transform Infrared Radiometer) study of plagioclase reported a relatively "wet" (approximately 320 parts per million) magma for primordial ferroan anorthosites (FANs). Another, a NanoSIMS study of alkali feldspar, reported a "wet" (approximately 1 weight percentage) felsic magma, but due to the differentiation processes required for silicic magmatism in the lunar crust, predicted an essentially "dry" (less than 100 parts per million) bulk Moon. Thus, despite evidence that appears to complicate the early "dry" Moon paradigm, there is no apparent unanimity among the measurements, even those on apatite. This disparity is clearly seen by the order of magnitude different water estimates for lunar "alkali-rich suite rocks" (Fig. 1). Some of the apparent differences may be explained by recent improvements in the apatite-based water estimates that better account for relative compatibilities of OH-, Cl, and F. In the present work, we seek to expand our understanding of the volatile abundances in early formed lunar magmas, their source reservoirs, and to address the potential role that felsic magmas play on the lunar hydrogen budget over time by employing NanoSIMS analysis of nominally anhydrous minerals.
A global building inventory for earthquake loss estimation and risk management
Jaiswal, K.; Wald, D.; Porter, K.
2010-01-01
We develop a global database of building inventories using taxonomy of global building types for use in near-real-time post-earthquake loss estimation and pre-earthquake risk analysis, for the U.S. Geological Survey's Prompt Assessment of Global Earthquakes for Response (PAGER) program. The database is available for public use, subject to peer review, scrutiny, and open enhancement. On a country-by-country level, it contains estimates of the distribution of building types categorized by material, lateral force resisting system, and occupancy type (residential or nonresidential, urban or rural). The database draws on and harmonizes numerous sources: (1) UN statistics, (2) UN Habitat's demographic and health survey (DHS) database, (3) national housing censuses, (4) the World Housing Encyclopedia and (5) other literature. ?? 2010, Earthquake Engineering Research Institute.

Physical activity levels are low amongst adolescent girls, and this population faces specific barriers to being active. Peer influences on health behaviours are important in adolescence and peer-led interventions might hold promise to change behaviour. This paper describes the protocol for a feasibility cluster randomised controlled trial of Peer-Led physical Activity iNtervention for Adolescent girls (PLAN-A), a peer-led intervention aimed at increasing adolescent girls' physical activity levels. A two-arm cluster randomised feasibility trial will be conducted in six secondary schools (intervention n = 4; control n = 2) with year 8 (12-13 years old) girls. The intervention will operate at a year group level and consist of year 8 girls nominating influential peers within their year group to become peer-supporters. Approximately 15 % of the cohort will receive 3 days of training about physical activity and interpersonal communication skills. Peer-supporters will then informally diffuse messages about physical activity amongst their friends for 10 weeks. Data will be collected at baseline (time 0 (T0)), immediately after the intervention (time 1 (T1)) and 12 months after baseline measures (time 2 (T2)). In this feasibility trial, the primary interest is in the recruitment of schools and participants (both year 8 girls and peer-supporters), delivery and receipt of the intervention, data provision rates and identifying the cost categories for future economic analysis. Physical activity will be assessed using 7-day accelerometry, with the likely primary outcome in a fully-powered trial being daily minutes of moderate-to-vigorous physical activity. Participants will also complete psychosocial questionnaires at each time point: assessing motivation, self-esteem and peer physical activity norms. Data analysis will be largely descriptive and focus on recruitment, attendance and data provision rates. The findings will inform the sample size required for a definitive trial. A detailed process evaluation using qualitative and quantitative methods will be conducted with a variety of stakeholders (i.e. pupils, parents, teachers and peer-supporter trainers) to identify areas of success and necessary improvements prior to proceeding to a definitive trial. This paper describes the protocol for the PLAN-A feasibility cluster randomised controlled trial which will provide the information necessary to design a fully-powered trial should PLAN-A demonstrate evidence of promise.

Objective To characterize the impact of widespread inventory management policies on stock-outs of essential drugs in Zambia’s health clinics and develop related recommendations. Methods Daily clinic storeroom stock levels of artemether-lumefantrine (AL) products in 2009–2010 were captured in 145 facilities through photography and manual transcription of paper forms, then used to determine historical stock-out levels and estimate demand patterns. Delivery lead-times and estimates of monthly facility accessibility were obtained through worker surveys. A simulation model was constructed and validated for predictive accuracy against historical stock-outs, then used to evaluate various changes potentially affecting product availability. Findings While almost no stock-outs of AL products were observed during Q4 2009 consistent with primary analysis, up to 30% of surveyed facilities stocked out of some AL product during Q1 2010 despite ample inventory being simultaneously available at the national warehouse. Simulation experiments closely reproduced these results and linked them to the use of average past monthly issues and failure to capture lead-time variability in current inventory control policies. Several inventory policy enhancements currently recommended by USAID | DELIVER were found to have limited impact on product availability. Conclusions Inventory control policies widely recommended and used for distributing medicines in sub-Saharan Africa directly account for a substantial fraction of stock-outs observed in common situations involving demand seasonality and facility access interruptions. Developing central capabilities in peripheral demand forecasting and inventory control is critical. More rigorous independent peer-reviewed research on pharmaceutical supply chain management in low-income countries is needed. PMID:27227412

The purpose of this study was to investigate the effects of a self-esteem improvement program on self-esteem and peer attachment in elementary school children with observed problematic behaviors. This study is a quasi-experimental study with a nonequivalent control group pretest-post-test design. A total of 47 fourth grade elementary school students participated in this study. The program was provided for 45 minutes once a week; a total of 12 sessions were completed with a group in the classroom for the experimental group. Child Problem-Behavior Screening Questionnaire was used to measure problematic behavior. Self-esteem was measured using the Rosenberg's Self-esteem Questionnaire, and peer attachment was measured using the Inventory of Parent and Attachment. Measuring was performed right after the program was done (post 1) and 1 month after the program was finished (post 2). To compare the differences in self-esteem and peer attachment between groups, repeated measures analysis of variance was used. Most participants in the experimental group were 10 years old (62.5%, range 10-11), male (52.0%) and with middle grade point average (64.0%). The self-esteem scores in the experimental group were significantly higher than those of the control group (F = 26.64, p < .001). The peer attachment scores in the experimental group were significantly higher than those of the control group (F = 6.48, p = .014). The self-esteem improvement program in this study improved the self-esteem and peer attachment in elementary school children. The self-esteem program helped acknowledge the peer's name and increased their connections. The program needs to be considered as a formal and consistent program. Copyright © 2015.

The health-related quality of life of school-aged children with high-functioning autism is poorly understood. The objectives of this study were to compare the health-related quality of life of children with high-functioning autism to that of typically developing peers and to compare child-self and parent-proxy reports of health-related quality of life of children. A cross-sectional study of children with high-functioning autism (n = 30) and peers (n = 31) was conducted using the Pediatric Quality of Life Inventory 4.0 Generic Core Scales. Children with high-functioning autism had significantly poorer health-related quality of life than peers whether reported by themselves (p < .001) or their parents (p < .001), although disagreement (intra-class coefficient = -.075) between children and parental scores suggested variance in points of view. This study specifically investigated health-related quality of life in children with high-functioning autism as compared to a sample of peers, from the child's perspective. It strengthens earlier findings that children with high-functioning autism experience poorer health-related quality of life than those without this disorder and points to the importance of clinicians working with families to identify areas in a child's life that promote or hinder their sense of well-being. © The Author(s) 2013.

To clarify the differences in dental health attitudes/behaviour among freshman dental students. Cross-cultural differences. Japan, Hong Kong and West China. The original version of the Hiroshima University-Dental Behavioural Inventory (HU-DBI) was written in Japanese. After testing the validity of both English and Chinese versions, the original version of the HU-DBI was administered to 58 freshman Japanese dental students, the English version to 43 Hong Kong Chinese peers and the Chinese version to 39 West Chinese peers. Significant cultural differences were found for 16 items out of 20. The most striking result was that the Japanese students were more likely to have used a dye to see how clean their teeth were, compared to their Chinese peers (P<0.001). The Chinese students were less likely to have a belief that they could clean their teeth well without using toothpaste (P<0.001), whereas higher percentages of the Chinese students worried about having bad breath (P<0.001). A higher percentage of the Hong Kong students reported that they regularly checked their teeth in a mirror than did their West Chinese or Japanese peers (P<0.05). There were considerable differences in dental health attitudes/behaviour among freshman dental students in the three cultural groups.

Mineral inventories of enstatite chondrites; (EH and EL) are strictly dictated by combined parameters mainly very low dual oxygen (fO2) and sulfur (fS2) fugacities. They are best preserved in the Almahata Sitta MS-17, MS-177 fragments, and the ALHA 77295 and MAC 88136 Antarctic meteorites. These conditions induce a stark change of the geochemical behavior of nominally lithophile elements to chalcophile or even siderophile and changes in the elemental partitioning thus leading to formation of unusual mineral assemblages with high abundance of exotic sulfide species and enrichment in the metallic alloys, for example, silicides and phosphides. Origin and mode of formation of these exotic chondrites, and their parental source regions could be best scrutinized by multitask research experiments of the most primitive members covering mineralogical, petrological, cosmochemical, and indispensably short-lived isotopic chronology. The magnitude of temperature and pressure prevailed during their formation in their source regions could eventually be reasonably estimated: pre- and postaccretionary could eventually be deduced. The dual low fugacities are regulated by the carbon to oxygen ratios estimated to be >0.83 and <1.03. These parameters not only induce unusual geochemical behavior of the elements inverting many nominally lithophile elements to chalcophile or even siderophile or anthracophile. Structure and mineral inventories in EL3 and EH3 chondrites are fundamentally different. Yet EH3 and EL3 members store crucial information relevant to eventual source regions and importantly possible variation in C/O ratio in the course of their evolution. EL3 and EH3 chondrites contain trichotomous lithologies (1) chondrules and their fragments, (2) polygonal enstatite-dominated objects, and (3) multiphase metal-rich nodules. Mineralogical and cosmochemical inventories of lithologies in the same EL3 indicate not only similarities (REE inventory and anomalies in oldhamite) but also distinct differences (sinoite-enstatite-graphite relationship). Oldhamite in chondrules and polygonal fragments in EL3 depict negative Eu anomaly attesting a common cosmochemical source. Metal-dominated nodules in both EL3 and EH3 are conglomerates of metal clasts and sulfide fragments in EH3 and concentrically zoned C-bearing metal micropebbles (≥25 μm ≤50 μm) in EL3 thus manifesting a frozen in unique primordial accretionary metal texture and composition. Sinoite-enstatite-diopside-graphite textures reveal a nucleation and growth strongly suggestive of fluctuating C/O ratio during their nucleation and growth in the source regions. Mineral inventories, sulfide phase relations, sinoite-enstatite-graphite intergrowth, carbon and nitrogen isotopic compositions of graphite, spatial nitrogen abundance in graphite in metal nodules, and last but not least 129I/129Xe and 53Mn/53Cr systematics negate any previously suggested melting episode, pre-accretionary or dynamic, in parental asteroids.

Adolescents who have been exposed to violence in the community often experience subsequent difficulties with academic achievement. Because competence in the classroom is a salient developmental task during the adolescent years, outcomes in this critical context can then have broader implications for social and psychological functioning. In the current study, we tested a hypothesized progression in which the association between violence exposure and deficient achievement is presumed to potentiate friendships with academically disengaged peers. We followed 415 urban adolescents (53 % girls; average age of 14.6 years) for a one-year period, with two annual assessment of psychosocial functioning. Exposure to violence in the community and academic engagement were assessed with a self-report inventory; reciprocated friendships were assessed with a peer interview; and achievement was indexed based on a review of school records. Consistent with our hypotheses, neighborhood violence was associated with deficient classroom achievement. Poor achievement, in turn, mediated associations between community violence exposure and low academic engagement among friends. Our findings highlight pathways though which exposure to community violence potentially predicts later dysfunction.

Consistent evidence has shown that one of the most significant influences on adolescent smoking is peer influence. There is considerable variation, however, in how peer influence is measured. This study constructs social network influence and selection variables from egocentric and sociometric data to compare their associations with smoking, with considerations of perceived smoking norms and adolescent popularity. Longitudinal data were collected in the 9th and 10th grades in October 2006 and 2007 from predominantly Hispanic/Latino adolescents in seven Southern California schools; among these adolescents, 1,950 completed surveys at both waves. Both cross-sectional (separately for 9th and 10th graders) and longitudinal models were estimated. An egocentric measure of perceived friend smoking was strongly and consistently associated with individual smoking (adjusted odds ratio [AOR] ≈ 1.80, p < .001), whereas its sociometric counterpart of friend self-report smoking was only associated with smoking in the 9th-grade cross-sectional models (e.g., AOR = 1.56, p < .001) and rarely in longitudinal models. Popularity, measured by proportion of nominations received by class size, was associated with smoking and becoming a smoker (AOR = 1.67, p < .001), whereas perceived norms were not, in longitudinal models. Friend selection was also associated with becoming a smoker (AOR = 1.32, p = .05). This study illustrates the utility of egocentric data for understanding peer influence and underscores the importance of perceptions and popularity as mechanisms that influence adolescent smoking.

Recovery-oriented services are a goal for policy and practice in the Australian mental health service system. Evidence-based reform requires an instrument to measure knowledge of recovery concepts. The Recovery Knowledge Inventory (RKI) was designed for this purpose, however, its suitability and validity for student health professionals has not been evaluated. The purpose of the current article is to report the psychometric features of the RKI for measuring nursing students' views on recovery. The RKI, a self-report measure, consists of four scales: (I) Roles and Responsibilities, (II) Non-Linearity of the Recovery Process, (III) Roles of Self-Definition and Peers, and (IV) Expectations Regarding Recovery. Confirmatory and exploratory factor analyses of the baseline data (n = 167) were applied to assess validity and reliability. Exploratory factor analyses generally replicated the item structure suggested by the three main scales, however more stringent analyses (confirmatory factor analysis) did not provide strong support for convergent validity. A refined RKI with 16 items had internal reliabilities of α = .75 for Roles and Responsibilities, α = .49 for Roles of Self-Definition and Peers, and α = .72, for Recovery as Non-Linear Process. If the RKI is to be applied to nursing student populations, the conceptual underpinning of the instrument needs to be reworked, and new items should be generated to evaluate and improve scale validity and reliability.

We tested two hypotheses derived from Moffitt’s (1993) taxonomic theory of antisocial behavior, both of which are central to her explanation for the rise in delinquency during adolescence. Specifically, we tested whether persistently delinquent individuals become more accepted by their peers during adolescence and whether individuals who abstain from delinquent behavior become less accepted. Participants were 4,359 adolescents from 14 communities in the PROSPER study, which assessed friendship networks and delinquency from 6th (M = 11.8 years) to 9th (M = 15.3 years) grade. We operationalized peer acceptance as: number of nominations received (indegree centrality), attractiveness as a friend (adjusted indegree centrality), and network bridging potential (betweenness centrality) and tested the hypotheses using multilevel modeling. Contrary to Moffitt’s hypothesis, persistently delinquent youth did not become more accepted between early and middle adolescence, and although abstainers were less accepted in early adolescence, they became more accepted over time. Results were similar for boys and girls; when differences occurred, they provided no support for Moffitt’s hypotheses for boys and were opposite of her hypotheses for girls. Sensitivity analyses using alternative strategies and additional data to identify persistently delinquent adolescents produced similar results. We explore the implications of these results for Moffitt’s assertions that social mimicry of persistently antisocial adolescents leads to increases in delinquency and that social isolation leads to abstention.

Moral disengagement processes are cognitive self-justification processes of transgressive actions that have been hypothesized to be learned and socialized within social contexts. The current study aimed at investigating socialization of moral disengagement by friends in two developmentally different age groups, namely late childhood (age: 9-10 years; n = 133, 42.9% girls) and early adolescence (age: 11-14 years; n = 236, 40.6% girls) over a 1-year period. Specifically, the current study examined whether similarity in moral disengagement between friends was the result of friends' influence or friend selection. Moreover, gender (42% girls), individual bullying behavior, and perceived popularity status were examined as potential moderators of socialization for moral disengagement within friendship networks. Self-report measures were used to assess moral disengagement, sociometric questions and a peer-nomination scale for friendship networks and bullying behavior, respectively. Longitudinal social network analysis (RSiena) was used to study change of moral disengagement in friendship networks during a 1-year interval. In early adolescence, friends were more likely to be similar to each other over time and this was explained only by influence processes and not by selection processes. Gender, bullying, and perceived popularity did not moderate the friends' influence on moral disengagement over time. Results indicate that self-justification processes change over time already in late childhood, but only in early adolescence this change is likely to be dependent upon peers' moral disengagement.

The bully/victim relationship was studied in a sample of elementary school children (N = 1,289 in first, third, and fifth grades). Three questions were tested. Does bullying involve a power differential between bully and victim? Are bully/victim dyads participants in a relationship, whether mutual liking or disliking? Does the gender composition of the bully/victim dyad moderate power differential and relational context patterns? Hierarchical linear modeling was used to analyze predictors of the reputational strength of bully/victim ties. The findings revealed that the bully/victim dyads most frequently nominated by peers were characterized by asymmetries in social status, where bullies were increasingly more popular than their victims, and by asymmetries in aggression, where bullies were increasingly less aggressive than their victims. Bullies and victims were likely to select one another as among the children that they least like. Most effects with respect to aggression, popularity, and relationships were moderated by the gender composition of the bully/victim dyad. Implications for a developmental psychopathology perspective on peer bullying and victimization are highlighted.

Bullying is a significant public health concern with lasting impacts on youth. Although environmental risk factors for bullying have been well-characterized, genetic influences on bullying are not well understood. This study explored the role of genetics on early childhood bullying behavior. Participants were 561 children who participated in a longitudinal randomized control trial of a preventive intervention beginning in first grade who were present for the first grade peer nominations used to measure early childhood bullying and who provided genetic data during the age 19-21 year follow-up in the form of blood or saliva. Measures included a polygenic risk score (PRS) derived from a conduct disorder genome wide association study. Latent profile analysis identified three profiles of bullying behaviors during early childhood. Results suggest that the PRS was significantly associated with class membership, with individuals in the moderate bully-victim profile having the highest levels of the PRS and those in the high bully-victim profile having the lowest levels. This line of research has important implications for understanding genetic vulnerability to bullying in early childhood. Copyright © 2018 Elsevier B.V. All rights reserved.

This study examined the associations between children's and adolescents' autistic-like social deficits and school and social adjustment as well as the moderating roles of age and gender in these associations. The sample consisted of 1321 students (48.7% boys) in Grade 1 to Grade 8 from northern Taiwan. Children's and adolescents' autistic-like social deficits were assessed using the Social Responsiveness Scale (SRS), and their school and social adjustment (i.e., academic performance, negative attitudes toward schoolwork/teachers/classmates, behavioral problems at schools, negative peer relationships, and problems with peers) were assessed using the Social Adjustment Inventory for Children and Adolescents (SAICA). Both measures were completed by the mothers of the participants. Results from the linear mixed models demonstrated that autistic-like social deficits were associated with poor academic performance, negative attitudes toward schoolwork, teachers, and classmates, behavioral problems at schools, negative peer relationships, and problematic peer interactions. Moreover, gender and/or age moderated the associations between autistic-like social deficits and school and social adjustment problems. For example, autistic-like social deficits were more strongly related to negative school attitude, school social problems, and negative peer relationships in boys than in girls. Further, autistic-like social deficits were more strongly related to problems with peers in older girls than in older boys or younger children (regardless of gender). In conclusion, the present study suggests that autistic-like social deficits may place children and adolescents at increased risk for social and school maladjustment and that the extent of maladjustment may vary with the child's age and gender and the domains of adjustment under discussion.

The association between attachment and mental health symptoms in adolescents in a post-conflict low resource setting has not been documented. We investigated the relationship between parent and peer attachment and posttraumatic stress, depression and anxiety symptoms in a sample of 551 adolescents aged 13-21 years old. Attachment quality was assessed using the Inventory of Parent and Peer Attachment (IPPA). Post-traumatic stress, depression and anxiety symptoms were assessed using the Impact of Events Scale Revised (IESR) and Hopkins Symptom Checklist for Adolescents (HSCL-37A) respectively. Gender differences in attachment relationships were determined using independent t-tests. Multivariate logistic regression was used to assess whether attachment relationships were independently associated with posttraumatic stress, depression and anxiety symptoms. Hierarchical linear regression analyses were conducted to explore the moderating role of war-related trauma. Our analyses revealed gender differences in attachment to parents, with males reporting stronger attachment than females. Parental attachment was protective against depression and anxiety symptoms but not posttraumatic stress symptoms after adjusting for potential confounders. Alienation by parents was independently associated with an increase in these mental health symptoms while peer attachment was not associated with any of these symptoms. However, in situations of severe trauma, our analyses showed that peer attachment was significantly protective against post-traumatic stress symptoms. Secure parental attachment is associated with better psychosocial adjustment in adolescents affected by war. Further, adolescents with secure peer attachment relationships in situations of severe war trauma may be less likely to develop posttraumatic stress symptoms. Interventions to enhance peer support in this post conflict setting would benefit this vulnerable population.

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.

Can You Hear What I Think? Theory of Mind in Young Children With Moderate Hearing Loss.
Netten, Anouk P; Rieffe, Carolien; Soede, Wim; Dirks, Evelien; Korver, Anna M H; Konings, Saskia; Briaire, Jeroen J; Oudesluys-Murphy, Anne Marie; Dekker, Friedo W; Frijns, Johan H M
The first aim of this study was to examine various aspects of Theory of Mind (ToM) development in young children with moderate hearing loss (MHL) compared with hearing peers. The second aim was to examine the relation between language abilities and ToM in both groups. The third aim was to compare the sequence of ToM development between children with MHL and hearing peers. Forty-four children between 3 and 5 years old with MHL (35 to 70 dB HL) who preferred to use spoken language were identified from a nationwide study on hearing loss in young children. These children were compared with 101 hearing peers. Children were observed during several tasks to measure intention understanding, the acknowledgement of the other's desires, and belief understanding. Parents completed two scales of the child development inventory to assess expressive language and language comprehension in all participants. Objective language test scores were available from the medical files of children with MHL. Children with MHL showed comparable levels of intention understanding but lower levels of both desire and belief understanding than hearing peers. Parents reported lower language abilities in children with MHL compared with hearing peers. Yet, the language levels of children with MHL were within the average range compared with test normative samples. A stronger relation between language and ToM was found in the hearing children than in children with MHL. The expected developmental sequence of ToM skills was divergent in approximately one-fourth of children with MHL, when compared with hearing children. Children with MHL have more difficulty in their ToM reasoning than hearing peers, despite the fact that their language abilities lie within the average range compared with test normative samples.

Physical activity levels are low amongst adolescent girls, and this population faces specific barriers to being active. Peer influences on health behaviours are important in adolescence, and peer-led interventions might hold promise to change behaviour. This paper describes the protocol for a feasibility cluster randomised controlled trial of Peer-Led physical Activity iNtervention for Adolescent girls (PLAN-A), a peer-led intervention aimed at increasing adolescent girls' physical activity levels. In addition, this paper describes an update that has been made to the protocol for the PLAN-A feasibility cluster randomised controlled trial. A two-arm cluster randomised feasibility trial will be conducted in six secondary schools (intervention n = 4; control n = 2) with year 8 (12-13 years old) girls. The intervention will operate at a year group level and consist of year 8 girls nominating influential peers within their year group to become peer supporters. Approximately 15% of the cohort will receive 3 days of training about physical activity and interpersonal communication skills. Peer supporters will then informally diffuse messages about physical activity amongst their friends for 10 weeks. Data will be collected at baseline (time 0 (T0)), immediately after the intervention (time 1 (T1)) and 12 months after baseline measures (time 2 (T2)). In this feasibility trial, the primary interest is in the recruitment of schools and participants (both year 8 girls and peer supporters), delivery and receipt of the intervention, data provision rates and identifying the cost categories for future economic analysis. Physical activity will be assessed using 7-day accelerometry, with the likely primary outcome in a fully powered trial being daily minutes of moderate-to-vigorous physical activity. Participants will also complete psychosocial questionnaires at each time point: assessing motivation, self-esteem and peer physical activity norms. Data analysis will be largely descriptive and focus on recruitment, attendance and data provision rates. The findings will inform the sample size required for a definitive trial. A detailed process evaluation using qualitative and quantitative methods will be conducted with a variety of stakeholders (i.e. pupils, parents, teachers and peer-supporter trainers) to identify areas of success and necessary improvements prior to proceeding to a definitive trial. The study will provide the information necessary to design a fully powered trial should PLAN-A demonstrate evidence of promise. This paper describes an update to the protocol for the PLAN-A feasibility cluster randomised controlled trial related to the data-linkage component. ISRCTN12543546.

The purpose of this study was to examine the relations of a measure of children's dispositional prosocial behavior (i.e., peer nominations) to individual differences in children's negative emotionality, regulation, and social functioning. Children with prosocial reputations tended to be high in constructive social skills (i.e., socially appropriate behavior and constructive coping) and attentional regulation, and low in negative emotionality. The relations of children's negative emotionality to prosocial reputation were moderated by level of dispositional attentional regulation. In addition, the relations of prosocial reputation to constructive social skills and parent-reported negative emotionality (for girls) increased with age. Vagal tone, a marker of physiological regulation, was negatively related to girls' prosocial reputation.

This study aimed to identify levels of depressive symptoms, social and personal college adjustment and peer support among nursing and midwifery students. Student mental health is of international concern, particularly among students who are undertaking professional qualifications in health care. Cross-sectional design. Data were collected in 2013 using the Centre for Epidemiology Depressive Symptoms Scale, two subscales of the Student Adaptation to College Questionnaire; and a subscale of the Peer Support Evaluation Inventory with 417 students in Ireland. Findings indicated that 34% of participants experienced depressive symptoms, 20% were poorly personally adjusted and 9% poorly socially adjusted. Most students had good levels of peer support. Statistically significant relationships were found between all key variables. Students in their second year of study had significantly higher rates of depressive symptoms. Participants who reported having poor relationships with their fathers were at higher risk and had more difficulties personally and socially adjusting to university life and study. The alcohol consumption of participants had a statistically significant relationship with depressive symptoms with higher consumption rates having a positive impact on symptoms. The mental health of undergraduates undertaking professional healthcare studies needs to be a key research, educational and clinical priority. High rates of adjustment and mental health difficulties, particularly in the second year of the programme need to be examined and more effective interventions developed. © 2016 John Wiley & Sons Ltd.
Psychological Profile of Sasang Typology: A Systematic Review
Park, Soo Hyun; Lee, Soo Jin; Kim, Myoung-geun; Wedding, Danny; Kwon, Young-Kyu
2009-01-01
A systematic review of studies related to the psychological characteristics of Sasang types was conducted with the goal of delineating generalizable psychological profiles based on Sasang typology, a traditional Korean medical typology with medical herbs and acupuncture that is characterized as personalized medicine. Journal articles pertaining to Sasang typology were collected using five electronic database systems in Korea and in the USA. As a result, 64 potentially relevant studies were identified and 21 peer-reviewed research articles that employed psychometric inventories were included. Beginning with the use of the Minnesota Multiphasic Personality Inventory in 1992, Myers-Briggs Type Indicator, NEO-Personality Inventory, Temperament and Character Inventory and other personality assessment tools were employed in the identified studies. Because data synthesis could not be carried out due to the heterogeneity of the studies, the present review article sought to delineate the mutual relevance of the studies based on research results pertaining to the correlation between the aforementioned psychological assessment instruments. Results of the review indicate that two super-factors, Extraversion and Neuroticism, serve as the foundation in regards to delineating personality constructs, such that the So-Yang type scored high on the Extraversion dimension and low on the Neuroticism dimension, while the So-Eum type scored low on the Extraversion dimension and high on the Neuroticism dimension. The present systematic review indicates that Sasang typology shares similarities with the Western psychological tradition. PMID:19745008

Interpersonal relationships play a key role in recovery from substance use disorders (SUDs). We examined the associations between problematic interpersonal styles, peer relationships, and treatment outcomes in a sample of U.S. military veterans in residential SUD treatment. Participants were 189 veterans enrolled in a residential SUD treatment program at a Department of Veterans Affairs medical center. Participants were interviewed at the time of treatment entry (baseline), one month into treatment, and 12months following discharge from treatment. More problematic interpersonal styles at treatment entry, measured by the Inventory of Interpersonal Problems-Circumplex (IIP-C), predicted more SUD symptoms 12months post-discharge (r=0.29, P<0.01). Results of a principal components analysis of the IIP-C subscales revealed three main factors of interpersonal styles: Passive, Cruel/Aloof, and Controlling. With the exception of the Passive factor, the relationship between these interpersonal styles and SUD symptoms 12months after discharge was mediated by relationship quality with peers one month in treatment: i.e., more problematic interpersonal styles at baseline predicted poorer relationship quality with peers at 1month, which in turn predicted more SUD symptoms at 12months. Results demonstrate the importance of assessing interpersonal styles among patients in residential SUD treatment, as well as potentially augmenting existing evidence-based psychosocial treatments with a focus on interpersonal styles.

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.

To explore the subjective quality of life (QoL) in children with Tourette Syndrome (TS) in China to provide a basis for more effective interference. A total of 107 patients and 107 controls were enrolled. Subjective QoL was investigated by Inventory of Subjective Life Quality, Family Environment Scale of Chinese Version, and the Yale Global Tic Severity Scale, and a case-control study was performed. The total score of subjective QoL and family life, school life, peer relationship, cognitive component, environment, self-awareness, cognitive component and depression experience in the TS were lower than control. Patients with co-morbid exhibited significantly lower scores within the subjective QoL family life, peer relationship, school life, self-awareness, and cognitive affective domains. The subjective QoL is impaired and it is important to control clinical symptoms and improve family environment for the improvement of the subjective QoL in TS.

The cross-cultural validity of feigning instruments and cut-scores is a critical concern for forensic mental health clinicians. This systematic review evaluated feigning classification accuracy and effect sizes across instruments and languages by summarizing 45 published peer-reviewed articles and unpublished doctoral dissertations conducted in Europe, Asia, and North America using linguistically, ethnically, and culturally diverse samples. The most common psychiatric symptom measures used with linguistically, ethnically, and culturally diverse samples included the Structured Inventory of Malingered Symptomatology, the Miller Forensic Assessment of Symptoms Test, and the Minnesota Multiphasic Personality Inventory (MMPI). The most frequently studied cognitive effort measures included the Word Recognition Test, the Test of Memory Malingering, and the Rey 15-item Memory test. The classification accuracy of these measures is compared and the implications of this research literature are discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

This investigation examined mediators of the longitudinal relation between negative affectivity and the development of problematic drinking behavior in adolescent boys and girls. In the present study, 499 early adolescents completed inventories of negative affectivity, attitudes toward delinquency, personal delinquency, and affiliation with delinquent peers. Positive attitudes toward delinquency emerged as the most consistent mediator and strongly predicted drinking frequency in various situations. Compared with personal delinquency, both attitudes toward delinquency and peer delinquency were superior predictors of affect-related drinking. Our results also demonstrated that positive attitudes toward delinquency mediated the relation between negative affectivity and later development of an alcohol use disorder. These findings suggest that a proneness to unpleasant affect impacts adolescent drinking by heightening risk for general rejection of normative behavior, rather than by increasing drinking as a means of managing affect. The importance and implications of testing delinquency variables together in the same model are discussed.

This study examined the utility of the newly developed Adolescent Friendship Attachment Scale (AFAS) for the prediction of adolescent psychological health and school attitude. High school students (266 males, 229 females) were recruited from private and public schools in the Australian Capital Territory with ages of participants ranging from 13 to 19 years. Self-report measures of depression, self-esteem, self-competence and school attitude were administered in addition to the AFAS and a short-form of the Inventory of Parental and Peer Attachment (IPPA). Regression analyses revealed that the AFAS Anxious and Avoidant scales added to the prediction of depression, self-esteem, self-competence, and school attitude beyond the contribution of the IPPA. It is concluded that the AFAS taps aspects of adolescent attachment relationships not assessed by the IPPA and provides a useful contribution to research and practice in the area of adolescent psycho-social adjustment.

Adolescence may involve increases in many behavioral problems and psychosocial maladaptation. Adolescents must successfully cope with these challenges to achieve positive developmental milestones. To investigate whether low parental attachment security among adolescents in Taiwan is associated with their demographic characteristics, psychosocial maladaptation, and depression. A cross-sectional survey. A total of 335 adolescents completed the questionnaires. The Inventory of Parent and Peer Attachment, the Chinese version of the Youth Self-Report, and the Beck Depression Inventory-II were used to survey the participants. Correlation and multiple linear regressions, using low attachment security as the response variable, were used in the statistical analysis. The prevalence of Taiwanese adolescents with low parental attachment security was 38.5%. Low parental attachment security in adolescents was significantly associated with parental remarriage status and psychosocial maladaptation. By considering these risk factors, nursing educators and nurses could develop effective interventions to strengthen parent-adolescent attachment security.

Prior research (R.R. McCrae, P.T. Costa, & M.S. Yik, 1996) using a Chinese translation of the Revised NEO Personality Inventory suggested substantial differences between Hong Kong and North American undergraduates. Study 1, with a sample of bilingual Hong Kong students (N = 162), showed that prior findings were not due simply to the translation. Study 2, with undergraduates of European and Chinese ancestry living in Canada (N = 633), suggested that more of the differences were cultural in origin. Study 3, which used peer ratings of Chinese students (N = 99), replicated most Study 2 results, suggesting that exposure to Canadian culture increased openness, cheerfulness, and prosocial behavior and attitudes. Differences in sense of competence and vulnerability to stress appeared to be due to different cultural standards for judging these traits. Together, the 3 studies illustrate an integrated approach to interpreting personality differences across cultures.

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.
The Cosmochemistry of Pluto: A Primordial Origin of Volatiles?
NASA Astrophysics Data System (ADS)
Glein, C. R.; Waite, J. H., Jr.

Pluto is a wonderland of volatiles. Nitrogen, methane, and carbon monoxide are the principal volatiles that maintain its tenuous atmosphere, and they have also created a mesmerizing landscape of icy geological features, including Pluto's iconic "heart". Recent data, particularly those returned by the New Horizons mission [1-3], allow us to begin testing hypotheses for the cosmochemical origins of these world-shaping species on Pluto. Here, we investigate if Pluto's volatiles could have been accreted in its building blocks. We take both bottom-up and top-down approaches in testing this hypothesis in terms of mass balance. We estimate Pluto's primordial inventory of volatiles by scaling a range of cometary abundances up to the ice mass fraction of Pluto. We also make estimates of the present and lost inventories of volatiles based on surface observations and interpretations, as well as different scenarios of atmospheric photochemistry and escape. We find that, if primordial Pluto resembled a giant comet with respect to volatile abundances, then the initial volatile inventory would have been sufficient to account for the estimated present and lost inventories. This consistency supports a primordial origin for Pluto's volatiles. However, the observed ratio of CO/N2 in Pluto's atmosphere [4] is several orders of magnitude lower than the nominal cometary value. We are currently using phase equilibrium and rate models to explore if volatile layering in Sputnik Planitia, or the destruction of CO in a past or present subsurface ocean of liquid water could explain the apparent depletion of CO on Pluto.

Dating and substance use in adolescent peer networks: a replication and extension.
Kreager, Derek A; Haynie, Dana L; Hopfer, Suellen
2013-03-01
The current report examined associations between romantic partner, peer and individual substance use behaviors in a sample of American adolescents. The report used two waves of data (8th and 9th grades) from the Partnerships to Enhance Resilience (PROSPER) intervention project and focused on dating couples and their friends in 54 sampled school-cohorts. Hierarchical logistic regression models examined the associations between friend, partner and friend-of-partner substance use and daters' future drinking and smoking. Surveys administered in rural Pennsylvania and Iowa secondary schools. A total of 744 dating couples. Student participants completed questionnaires that assessed substance use, background characteristics and dating and friend nominations. Friend, partner and friend-of-partner substance use were assessed at each wave directly from respective reports. Consistent with a bridging hypothesis, friends-of-partner drinking had a strong and independent association with subsequent drunkenness (b = 1.40, P < 0.01) and drinking (b = 0.82, P < 0.01) among daters, and these associations did not vary by gender. A similar association was not observed for smoking, where partner (b = 0.77, P < 0.01) and direct friends (b = 1.19, P < 0.05) smoking showed strong and significant associations with future smoking, but friends-of-partner smoking did not (b = -0.44, P > 0.10). Romantic partner and peer behaviors have substantially different associations with adolescent drinking and smoking. Intervention efforts aimed at reducing teenage smoking should be aimed at proximal peer and romantic relationships, whereas interventions of teenage drinking should also include the wider circle of indirect friends. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.

The objectives were to develop a scientifically sound and feasible peer-to-peer assessment model that allows health-care organizations to evaluate patient safety in cardiovascular operating rooms and to establish safety priorities for improvement. The locating errors through networked surveillance study was conducted to identify hazards in cardiac surgical care. A multidisciplinary team, composed of organizational sociology, organizational psychology, applied social psychology, clinical medicine, human factors engineering, and health services researchers, conducted the study. We used a transdisciplinary approach, which integrated the theories, concepts, and methods from each discipline, to develop comprehensive research methods. Multiple data collection was involved: focused literature review of cardiac surgery-related adverse events, retrospective analysis of cardiovascular events from a national database in the United Kingdom, and prospective peer assessment at 5 sites, involving survey assessments, structured interviews, direct observations, and contextual inquiries. A nominal group methodology, where one single group acts to problem solve and make decisions was used to review the data and develop a list of the top priority hazards. The top 6 priority hazard themes were as follows: safety culture, teamwork and communication, infection prevention, transitions of care, failure to adhere to practices or policies, and operating room layout and equipment. We integrated the theories and methods of a diverse group of researchers to identify a broad range of hazards and good clinical practices within the cardiovascular surgical operating room. Our findings were the basis for a plan to prioritize improvements in cardiac surgical care. These study methods allowed for the comprehensive assessment of a high-risk clinical setting that may translate to other clinical settings.

2013-04-01
This study examined longitudinal associations between direct and relational peer victimization (DV/RV) and self-reported social phobia (SP) among adolescents from 15 to 17 years of age, controlling for depression and family socioeconomic covariates. A total of 3,278 Finnish adolescents with a mean age of 15.5 years were surveyed at baseline (T1), and followed up 2 years afterwards (T2) their mean age being 17.6 years. In all, 2,070 adolescents were reached for the follow-up. Both types of victimization were assessed with structured questions, SP with the Social Phobia Inventory, and depression with the 13-item Beck Depression Inventory. Socioeconomic covariates were assessed with items from the Life Events Checklist. Frequency of victimization and SP were assessed at T1 and T2, and incidence and persistence from T1 to T2. Longitudinal associations between victimization and SP were examined with three logistic regression analyses with depression and socioeconomic covariates controlled for, with SP, DV, and RV in turn as the dependent endpoint (T2) variables. Among boys a bidirectional association between DV and SP was found with DV both predicting SP [Odds Ratio (OR) 2.6] and being predicted by SP (OR 3.9). Among girls RV predicted SP (OR 2.8), but not vice versa, while depression in turn predicted DV (OR 4.3). Direct victimization and SP have a bidirectional association among boys, while among girls RV increases the risk of subsequent SP.
Consonant Acquisition in Young Cochlear Implant Recipients and Their Typically Developing Peers
Jung, Jongmin; Ertmer, David J.
2017-01-01
Purpose Consonant acquisition was examined in 13 young cochlear implant (CI) recipients and 11 typically developing (TD) children. Method A longitudinal research design was implemented to determine the rate and nature of consonant acquisition during the first 2 years of robust hearing experience. Twenty-minute adult–child (typically a parent) interactions were video and audio recorded at 3-month intervals following implantation until 24 months of robust hearing experience was achieved. TD children were similarly recorded between 6 and 24 months of age. Consonants that were produced twice within a 50-utterance sample were considered “established” within a child's consonant inventory. Results Although the groups showed similar trajectories, the CI group produced larger consonant inventories than the TD group at each interval except for 21 and 24 months. A majority of children with CIs also showed more rapid acquisition of consonants and more diverse consonant inventories than TD children. Conclusions These results suggest that early auditory deprivation does not significantly affect consonant acquisition for most CI recipients. Tracking early consonant development appears to be a useful way to assess the effectiveness of cochlear implantation in young recipients. PMID:28474085
The power of (Mis)perception: Rethinking suicide contagion in youth friendship networks.
Zimmerman, Gregory M; Rees, Carter; Posick, Chad; Zimmerman, Lori A
2016-05-01
Suicide is a leading cause of death among youth. In the wake of peer suicide, youth are vulnerable to suicide contagion. But, questions remain about the mechanisms through which suicide spreads and the accuracy of youths' estimates of friends' suicidal behaviors. This study addresses these questions within school-aged youths' friendship networks. Social network data were drawn from two schools in the National Longitudinal Study of Adolescent to Adult Health, from which 2180 youth in grades 7-12 nominated up to ten friends. A measure of "perceived" friends' attempted suicide was constructed based on respondents' reports of their friends' attempted suicide. This measure was broader than a "true" measure of friends' attempted suicide, constructed from self-reports of nominated friends who attended respondents' schools. Sociograms graphically represented the accuracy with which suicide attempters estimated friends' suicide attempts. Results from cross-tabulation with Chi-square analysis indicated that approximately 4% of youth (88/2180) attempted suicide, and these youth disproportionately misperceived (predominantly overestimated) friends' suicidal behaviors, compared to non-suicide-attempters. Penalized logistic regression models indicated that friends' self-reported attempted suicide was unrelated to respondent attempted suicide. But, the odds of respondent attempted suicide were 2.54 times higher (95% CI, 1.06-6.10) among youth who accurately perceived friends' attempted suicide, and 5.40 times higher (95% CI, 3.34-8.77) among youth who overestimated friends' attempted suicide. The results suggest that at-risk youth overestimate their friends' suicidal behaviors, which exacerbates their own risk of suicidal behavior. Methodologically, this suggests that a continued collaboration among network scientists, suicide researchers, and medical providers is necessary to further examine the mechanisms surrounding this phenomenon. Practically, it is important to screen at-risk youth for exposure to peer suicide and to use the social environment created by adolescent friendship networks to empower and support youth who are susceptible to suicidal thoughts and behaviors.

Adolescent Desire for Cosmetic Surgery: Associations with Bullying and Psychological Functioning.
Lee, Kirsty; Guy, Alexa; Dale, Jeremy; Wolke, Dieter
2017-05-01
Adolescent bullying may be a key driver of interest in cosmetic surgery. This study examined the extent of such interest and whether any effect was sex-specific, and examined psychological functioning as a potential mechanism through which bullying involvement may lead to a wish for cosmetic surgery. A two-stage design was used. In the first stage, 2782 adolescents (aged 11 to 16 years) were screened for bullying involvement using self-reports and peer nominations. In the second stage, 752 adolescents who were bullies, victims, bully-victims, or uninvolved in bullying reported their desire for cosmetic surgery. Psychological functioning was constructed as a composite of self-esteem and emotional problems (assessed at stage 1) and body-esteem scores (assessed at stage 2). Adolescents involved in bullying in any role were significantly more interested in cosmetic surgery than uninvolved adolescents. Desire for cosmetic surgery was greatest in adolescents who were bullied (victims and bully-victims) and girls. Desire for cosmetic surgery was highest in girls, but sex did not interact with bullying role. Being victimized by peers resulted in poor psychological functioning, which increased desire for cosmetic surgery. In contrast, desire for cosmetic surgery in bullies was not related to psychological functioning, which was in the normal range. Bullying victimization is related to poor psychological functioning, and both are related to a greater desire for cosmetic surgery in adolescents. Cosmetic surgeons should screen candidates for psychological vulnerability and may want to include a short screening questionnaire for a history of peer victimization.
ISP33 standard problem on the PACTEL facility
DOE Office of Scientific and Technical Information (OSTI.GOV)
Purhonen, H.; Kouhia, J.; Kalli, H.
ISP33 is the first OECD/NEA/CSNI standard problem related to VVER type of pressurized water reactors. The reference reactor of the PACTEL test facility, which was used to carry out the ISP33 experiment, is the VVER-440 reactor, two of which are located near the Finnish city of Loviisa. The objective of the ISP33 test was to study the natural circulation behaviour of VVER-440 reactors at different coolant inventories. Natural circulation was considered as a suitable phenomenon to focus on by the first VVER related ISP due to its importance in most accidents and transients. The behaviour of the natural circulation wasmore » expected to be different compared to Western type of PWRs as a result of the effect of horizontal steam generators and the hot leg loop seals. This ISP was conducted as a blind problem. The experiment was started at full coolant inventory. Single-phase natural circulation transported the energy from the core to the steam generators. The inventory was then reduced stepwise at about 900 s intervals draining 60 kg each time from the bottom of the downcomer. the core power was about 3.7% of the nominal value. The test was terminated after the cladding temperatures began to rise. ATHLET, CATHARE, RELAP5 (MODs 3, 2.5 and 2), RELAP4/MOD6, DINAMIKA and TECH-M4 codes were used in 21 pre- and 20 posttest calculations submitted for the ISP33.« less
The influence of shyness on children's test performance.
Crozier, W Ray; Hostettler, Kirsten
2003-09-01
Research has shown that shy children differ from their peers not only in their use of language in routine social encounters but also in formal assessments of their language development, including psychometric tests of vocabulary. There has been little examination of factors contributing to these individual differences. To investigate cognitive-competence and social anxiety interpretations of differences in children's performance on tests of vocabulary. To examine the performance of shy and less shy children under different conditions of test administration, individually with an examiner or among their peers within the familiar classroom setting. The sample consisted of 240 Year 5 pupils (122 male, 118 female) from 24 primary schools. Shy and less shy children, identified by teacher nomination and checklist ratings, completed vocabulary and mental arithmetic tests in one of three conditions, in a between-subjects design. The conditions varied individual and group administration, and oral and written responses. The conditions of test administration influenced the vocabulary test performance of shy children. They performed significantly more poorly than their peers in the two face-to-face conditions but not in the group test condition. A comparable trend for the arithmetic test was not statistically significant. Across the sample as a whole, shyness correlated significantly with test scores. Shyness does influence children's cognitive test performance and its impact is larger when children are tested face-to-face rather than in a more anonymous group setting. The results are of significance for theories of shyness and have implications for the assessment of schoolchildren.
Social motivation in Qatari schools and their relation to school achievement.
Nasser, Ramzi
2014-10-01
This study assessed the relation between school-social motivation and student academic achievement. A factor analysis was performed on a set of school-social items selected a priori from three measures of school motivation: the Inventory of School Motivation, the General Achievement Goals Orientation Scale, and the Facilitating Conditions Scale. Three factors with fewer items represented Global Motivation, Peer Help, and Social Power. Hierarchical regression analysis showed social motivation measures were weak predictors of achievement scores in the various content areas. Findings are discussed in the context of Qatari education and culture.

This paper introduces new longitudinal network data from the "Promoting School-Community-University Partnerships to Enhance Resilience" or "PROSPER" peers project. In 28 communities, grade-level sociometric friendship nominations were collected from two cohorts of middle school students as they moved from 6(th), to 9(th) grade. As an illustration and description of these longitudinal network data, this paper describes the school popularity structure, changes in popularity position, and suggests linkages between popularity trajectory and substance use. In the cross-section, we find that the network is consistent with a hierarchical social organization, but exhibits considerable relational change in both particular friends and position at the individual level. We find that both the base level of popularity and the variability of popularity trajectories effect substance use.

The purpose of this study was to examine relations between mother-child attachment and social initiative and withdrawal in Chinese urban children. Participants were 487 school-aged children (247 boys, 240 girls) in Shanghai, the People's Republic of China. Data on mother-child attachment styles were collected from children's self-reports. Information concerning social initiative and social withdrawal (i.e., shyness and social disinterest) was obtained from peer nomination. Path analyses revealed that secure attachment was positively associated with social initiative, whereas ambivalent-insecure attachment was positively associated with shyness. However, avoidant-insecure attachment was not significantly associated with social disinterest. In addition, a number of gender and developmental differences were also observed.

burnout and quality of life are poorly studied phenomena in postgraduate students, and its effects are unknown. The aim was to investigate the relationship between quality of life and burnout in medical residents. a longitudinal study was performed. We included medical residents who began their postgraduate studies in 2010. The Spanish version of the Quality of Life Profile for the Chronically Ill (PLC, according to its initials in German), and the Maslach Burnout Inventory specific to physicians were applied at the beginning, and six and 12 months later. Descriptive statistics were used for nominal variables. Chi-square and ANOVA were applied to numerical variables. we included 45 residents, the average age was 26.9 ± 2.93 years, 18 (40 %) were female and 27 (60 %) were male. The PLC survey found significant decrease in four of the six scales assessed in the three measurements. The Maslach Burnout Inventory found high levels of emotional exhaustion in the three tests, low levels of depersonalization and low personal gains at the beginning, rising at six and 12 months. The most affected specialty was Internal Medicine. burnout and impaired quality of life for residents exist in postgraduate physicians and it is maintained during the first year of residency.
Rural hospital focus: accommodation.
Couper, I D
2003-01-01
Rural and Remote Health is committed to the task of providing a freely accessible, international, peer-reviewed evidence base for rural and remote health practice. Inherent in this aim is a recognition of the universal nature of rural health issues that transcends both regional interests and local culture. While RRH is already publishing peer-reviewed material, the Editorial Board believes many articles of potential worth are largely inaccessible due to their primary publication in small-circulation, paper-based journals whose readership is geographically limited. In order to augment our already comprehensive, international evidence base, the RRH Editorial Board has decided to republish, with permission, selected articles from such journals. This will also give worthwhile small-circulation articles the wide audience only a web-based journal can offer. The RRH editorial team encourages journal users to nominate similar, suitable articles from their own world region. This article 'Rural hospital focus: accommodation', is third in our series. It first appeared in South African Family Practice 2000; 22 (7), and is reproduced here in its original form, with kind permission of both publisher and author, prominent South African rural doctor, Professor Ian Couper. 'Rural hospital focus' was the title of the SAFP column which presented this article.
Does Humor Explain Why Relationally Aggressive Adolescents Are Popular?
Bowker, Julie C.; Etkin, Rebecca G.
2013-01-01
The association between relational aggression and popularity during early adolescence is well established. Yet, little is known about why, exactly, relationally aggressive young adolescents are able to achieve and maintain high popular status among peers. The present study investigated the mediating role of humor in the association between relational aggression and popularity during early adolescence. Also considered was whether the association between relational aggression and humor varies according to adolescents’ gender and their friends’ levels of relational aggression. Participants were 265 sixth-grade students (48% female; 41% racial/ethnic minority; Mage = 12.04 years) who completed peer nomination and friendship measures in their classrooms at two time points (Wave 1: February; Wave 2: May). The results indicated that Wave 1 relational aggression was related to Wave 1 and 2 popularity indirectly through Wave 1 humor, after accounting for the effects of Wave 1 physical aggression, ethnicity, and gender. Additional analyses showed that relational aggression and humor were related significantly only for boys and for young adolescents with highly relationally aggressive friends. The results support the need for further research on humor and aggression during early adolescence and other mechanisms by which relationally aggressive youth achieve high popular status.

Recent advancement of land-based mobile mapping enables rapid and cost-effective collection of highquality road related spatial information. Mobile Mapping Systems (MMS) can provide spatial information with subdecimeter accuracy in nominal operation environments. However, performance in challenging environments such as tunnels is not well characterized. The Norwegian Public Roads Administration (NPRA) manages the country's public road network and its infrastructure, a large segment of which is represented by road tunnels (there are about 1 000 road tunnels in Norway with a combined length of 800 km). In order to adopt mobile mapping technology for streamlining road network and infrastructure management and maintenance tasks, it is important to ensure that the technology is mature enough to meet existing requirements for object positioning accuracy in all types of environments, and provide homogeneous accuracy over the mapping perimeter. This paper presents results of a testing campaign performed within a project funded by the NPRA as a part of SMarter road traffic with Intelligent Transport Systems (ITS) (SMITS) program. The testing campaign objective was performance evaluation of high end commercial MMSs for inventory of public areas, focusing on Global Navigation Satellite System (GNSS) signal degraded environments.

The Checklist for Early Recognition and Treatment of Acute Illness (CERTAIN) is an international collaborative project with the overall objective of standardizing the approach to the evaluation and treatment of critically ill patients world-wide, in accordance with best-practice principles. One of CERTAIN's key features is clinical decision support providing point-of-care information about common acute illness syndromes, procedures, and medications in an index card format. This paper describes 1) the process of developing and validating the content for point-of-care decision support, and 2) the content management system that facilitates frequent peer-review and allows rapid updates of content across different platforms (CERTAIN software, mobile apps, pdf-booklet) and different languages. Content was created based on survey results of acute care providers and validated using an open peer-review process. Over a 3 year period, CERTAIN content expanded to include 67 syndrome cards, 30 procedure cards, and 117 medication cards. 127 (59 %) cards have been peer-reviewed so far. Initially MS Word® and Dropbox® were used to create, store, and share content for peer-review. Recently Google Docs® was used to make the peer-review process more efficient. However, neither of these approaches met our security requirements nor has the capacity to instantly update the different CERTAIN platforms. Although we were able to successfully develop and validate a large inventory of clinical decision support cards in a short period of time, commercially available software solutions for content management are suboptimal. Novel custom solutions are necessary for efficient global point of care content system management.

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.

This report summarizes the results of AFRIMETS.M.M-S6 mass standards comparison conducted between eleven participating laboratories/countries. Two sets of five weights with nominal values 100 mg, 100 g, 500 g, 1 kg and 5 kg were used as the traveling standards. These nominal values were decided from the needs of participating laboratories submitted to the pilot laboratory through a questionnaire and agreed upon by all participants. The traveling standards were hand carried between laboratories starting from February 2014 and were received from the last participants in October 2014. The programme was coordinated by National Metrology Institute of South Africa (NMISA), who provided the travelling standards and reference values for the comparison. The corrections to the BIPM as-maintained mass unit [5] have insignificant influence on the results of this comparison. Main text To reach the main text of this paper, click on Final Report.

An fMRI Study of Grammatical Morpheme Processing Associated with Nouns and Verbs in Chinese
Yu, Xi; Bi, Yanchao; Han, Zaizhu; Law, Sam-Po
2013-01-01
This study examined whether the degree of complexity of a grammatical component in a language would impact on its representation in the brain through identifying the neural correlates of grammatical morpheme processing associated with nouns and verbs in Chinese. In particular, the processing of Chinese nominal classifiers and verbal aspect markers were investigated in a sentence completion task and a grammaticality judgment task to look for converging evidence. The Chinese language constitutes a special case because it has no inflectional morphology per se and a larger classifier than aspect marker inventory, contrary to the pattern of greater verbal than nominal paradigmatic complexity in most European languages. The functional imaging results showed BA47 and left supplementary motor area and superior medial frontal gyrus more strongly activated for classifier processing, and the left posterior middle temporal gyrus more responsive to aspect marker processing. We attributed the activation in the left prefrontal cortex to greater processing complexity during classifier selection, analogous to the accounts put forth for European languages, and the left posterior middle temporal gyrus to more demanding verb semantic processing. The overall findings significantly contribute to cross-linguistic observations of neural substrates underlying processing of grammatical morphemes from an analytic and a classifier language, and thereby deepen our understanding of neurobiology of human language.

The best visual expression of mountain permafrost are rockglaciers, which, in contrast to the permafrost itself, can be mapped and monitored directly using remotely sensed data. Studies carried out in various parts of the European Alps have shown surface acceleration of rockglaciers and even destabilization of several such landforms over the two last decades, potentially related to the changing permafrost creep conditions. Changes in rockglacier motion are therefore believed to be the most indicative short- to medium-term response of rockglaciers to environmental changes and thus an indicator of mountain permafrost conditions in general. The ESA DUE GlobPermafrost project develops, validates and implements EO products to support research communities and international organizations in their work on better understanding permafrost characteristics and dynamics. Within this project we are building up a worldwide long-term monitoring network of active rockglacier motion investigated using remote sensing techniques. All sites are analysed through a uniform set of data and methods, and results are thus comparable. In order to quantify the rate of movement and the relative changes over time we consider two remote sensing methods: (i) matching of repeat optical data and (ii) satellite radar interferometry. In this contribution, we focus on the potential of recent high spatial resolution SAR data for the analysis of periglacial processes in mountain environments with special attention to the Ile and Kungöy Ranges of Northern Tien Shan at the border between Kazakhstan and Kyrgyzstan, an area which contains a high number of large and comparably fast (> 1m/yr) rockglaciers and is of interest as dry-season water resource and source of natural hazards. As demonstrated in the past with investigations conducted in the Swiss Alps, the visual analysis of differential SAR interferograms can be employed for the rough estimation of the surface deformation rates of rockglaciers and other slope instabilities into different classes (e.g. cm/day, dm/month, cm/month and cm/yr). More sophisticated SAR interferometric approaches like Persistent Scatterer Interferometry (PSI) or Short Baseline Interferometry (SBAS) are only able to detect points moving with velocities below a few cm/yr respectively several dm/yr in the Line-Of-Sight (LOS) direction, because of phase unwrapping issues. For our analysis in the Tien Shan we considered SAR interferograms with short baselines and acquisition time intervals between 1 day and approximately one year. Satellite images from the ERS-1/2 tandem mission in 1998-1999, ALOS-1 PALSAR-1 between 2006-2010 (46 days nominal repeat cycle), ALOS-2 PALSAR-2 between 2014 and 2016 (14 days nominal repeat cycle), and Sentinel-1 between 2015 and 2016 (12 days nominal repeat cycle) were used. Images acquired along both ascending and descending geometries and during summer (snow-free) and winter (frozen snow) conditions were employed. For topographic reference and orthorectification we computed in-house a Digital Elevation Model from TanDEM-X acquisitions of ascending and descending orbits. Phase unwrapping to derive the LOS displacement was attempted only locally for selected landforms with a moderate (e.g. < 50 cm/yr) rate of motion. Our inventory of rockglaciers and other periglacial processes in the Northern Tien Shan includes so far more than 500 objects over an area of more than 3000 km2. In future, our inventory will be compared to other existing inventories compiled in field or with air photos. In addition, the long-term monitoring of rockglacier motion will be performed taking advantage of the synergies between repeat optical and radar satellite data. The combined approach is useful for the confirmation of the activity, filling spatial and/or temporal gaps, computing the historical fast motion of rockglaciers from optical data and the slow motion from SAR interferometry, and to compare multi-annual rates of motion (optical data) with seasonal activities (SAR interferometry).

Background: This analysis was undertaken to determine whether adolescents who screened positive for high-risk substance use with the CRAFFT questions were also more likely to engage in risky sexual behaviors than their peers, and to determine the test-retest reliability of a substance use related sexual risk behaviors inventory. Methods: 12- to 18-year-old clinic patients completed a multi-part questionnaire that included 8 demographic items, the CRAFFT substance use screen, and a 14-item scale assessing sexual behaviors associated with substance use. Participants were invited to return one week later to complete an identical assessment battery. Results: Of the 305 study participants, 49 (16.1%) had a positive CRAFFT screen (score of 2 or greater, indicating high risk for substance abuse/dependence) and 101 (33.9%) reported sexual contact during the past 90 days. After controlling for gender, age, race, and number of parents in household, adolescents with a positive CRAFFT screen had significantly greater odds of having sexual contact after using alcohol or other drugs, of having a sexual partner who used alcohol or other drugs, of having sex without a condom, and of having multiple sexual partners within the past year, compared to their CRAFFT negative peers. The substance use related sexual risk behaviors inventory has acceptable test-retest reliability and the 10 frequency questions have scale-like properties with acceptable internal consistency (standardized Cronbach's Alpha = .79). Conclusion: Clinicians should pay special attention to counseling CRAFFT-positive adolescents regarding use of condoms, and the risks associated with sexual activity with multiple partners, while intoxicated, or with an intoxicated partner.

The aim of this study was to assess the impact of two teaching interventions (ultrasound and arthroscopy) in a peer teaching (PT) environment on anatomy examination scores and also to examine the influence of gender and learning style on these scores. We randomly assigned 484 second year medical students to one of three groups: musculoskeletal ultrasound (MSUS), arthroscopy (ASC) and control (CON). The MSUS- and the ASC-group attended two additional training sessions in ultrasound or arthroscopy; the CON-group received no additional lessons. Students were asked to complete Kolb's Learning Style Inventory test. We assessed differences in anatomical knowledge (multiple choice (MC) exam) and subjective evaluation with respect to gender and learning style. There were no relevant differences between the three groups regarding the MC exam. Acceptance of the peer teaching concept was good. All students preferred ultrasound to arthroscopy and thought that they learned more from ultrasound despite the fact that they rated the instructors as less competent and needed more time to gain in-depth knowledge. There was no significant effect of gender on evaluation results. Arthroscopy was best enjoyed by accommodators according to Kolb's Inventory and least by divergers, who found that they had learned a lot through ultrasound. The improvement in spatial conceptualization was greatest for accommodators and worst for assimilators. Gender and learning style had no impact on quantitative parameters. Qualitative analysis, however, revealed differences for learning style and further evaluation is warranted to assess the impact on medical education. Copyright © 2016 Elsevier GmbH.

Direct observation of peer relating is potentially a sensitive and ecologically valid measure of child social functioning, but there has been a lack of standardised methods. The Manchester Inventory for Playground Observation (MIPO) was developed as a practical yet rigorous assessment of this kind for 5-11 year olds. We report on the initial reliability and validity of the MIPO and its ability to distinguish social impairments within different psychopathologies. We observed 144 clinically referred children aged 5;00-11;11 (mean 8.8) years with Externalising (n = 44), Internalising (n = 19), Autism Spectrum Disorders (n = 39) or Specific Language Impairment (n = 42), and 44 class-controls, in naturalistic playground interaction. Observers, blind to clinical diagnosis, completed the MIPO and the teacher checklist from the Social Skills Rating System (SSRS). MIPO items showed high internal consistency (alpha = .924; all 'alpha if item deleted' values>.91), inter-observer reliability (mean κ(w) = .77) and test-retest stability (over 2 weeks; mean κ(w) = .58). MIPO totals showed convergence with SSRS (n = 68, r(s) = .78, p<.01) and excellent discrimination between case and control (sensitivity = 0.75 and specificity = 0.88, AUC = .897). Externalising, Autistic Spectrum and Language Impaired groups showed distinct profiles of MIPO impairment consistent with theory:Internalising disorders less so. 65.3% of clinical cases were classified accurately for primary diagnosis. The MIPO shows reliability and validity as a measure of children's social functioning relevant in developmental research and as a clinical tool to aid differential diagnosis and intervention planning.

Autism spectrum disorder (ASD) is a lifelong developmental disability characterized by deficits in social communication and social interaction across multiple contexts. Existing literature on social relationships and well-being among adolescents with ASD in Asian countries is scant. This study compared the perceptions of adolescents with ASD with those of their neurotypical peers toward their friendship quality, activity participation, and emotional well-being, and examined the relationships between friendship quality, activity participation, and emotional well-being. The study participants-101 adolescents with ASD and 101 neurotypical peers, aged 10-19 years-completed the following self-administered questionnaires: the Friendship Quality Questionnaire, the Child and Adolescent Scale of Participation, the Beck Anxiety Inventory, and the short-form UCLA loneliness scale. Adolescents with ASD reported lower friendship quality, lower school participation, and higher levels of anxiety and loneliness compared to their neurotypical peers. Loneliness correlated negatively with friendship quality and school participation and positively with anxiety. Adolescents with ASD experienced increased levels of anxiety when low friendship quality was accompanied by greater loneliness. These findings reveal that friendship quality, school participation, and loneliness have a considerable effect on the emotional well-being of adolescents with ASD, thus indicating the need for therapeutic interventions that address interpersonal relationships and emotional well-being.

An optional astronaut selection strategy would select-in individuals on the basis of personality attributes associated with superior performance. Method: A test battery, the Astronaut Personal Characteristics Inventory (ASTROPCI) was developed which assesses positive and negative components of achievement, motivation, and interpersonal orientations and skills. The battery was administered to one hundred three astronaut candidates and sixty-six current U.S. Shuttle astronauts. To determine performance, a series of conceptual areas related to space flight performance were defined. Astronauts rated their peers on each of these dimensions. Ratings were obtained on all eighty-four current astronauts (excluding those selected in 1990). In addition to peer ratings, supervisor assessments of the same dimensions were obtained for each astronaut. Results: Cluster and factor analysis techniques were employed to isolate subgroups of astronauts. Those astronauts with both high achievement needs and interpersonal skills were most often rated among the top five by their peers and least often rated among the lowest five. A number of scales discriminated between astronauts rated high and low on one or more performance dimensions. Conclusions: The results parallel findings from the personality assessment of individuals in other demanding professions, including aircraft pilots and research scientists, suggesting that personality factors are significant determinants to performance in the space environment.

Nearly three decades of research has demonstrated that the impoundment of rivers and the flooding of terrestrial ecosystems behind dams can increase rates of greenhouse gas emission, particularly methane. The 2006 IPCC Guidelines for National Greenhouse Gas Inventories includes a methodology for estimating methane emissions from flooded lands, but the methodology was published as an appendix to be used as a `basis for future methodological development' due to a lack of data. Since the 2006 Guidelines were published there has been a 6-fold increase in the number of peer reviewed papers published on the topic including reports from reservoirs in India, China, Africa, and Russia. Furthermore, several countries, including Iceland, Switzerland, and Finland, have developed country specific methodologies for including flooded lands methane emissions in their National Greenhouse Gas Inventories. This presentation will include a review of the literature on flooded land methane emissions and approaches that have been used to upscale emissions for national inventories. We will also present ongoing research in the United States to develop a country specific methodology. In the U.S., research approaches include: 1) an effort to develop predictive relationships between methane emissions and reservoir characteristics that are available in national databases, such as reservoir size and drainage area, and 2) a national-scale probabilistic survey of reservoir methane emissions linked to the National Lakes Assessment.

The current study used the Behavior Rating Inventory of Executive Function-Preschool Version (BRIEF-P; Gioia, Espy, & Isquith, 2003), a rating scale designed to investigate executive behaviors in everyday activities, to examine the executive functioning of preschool children with specific language impairment (SLI) relative to their typically developing (TD) peers. Nineteen preschool children with SLI were age- and gender-matched to 19 TD peers. Both parents and teachers of the participants completed the BRIEF-P. The executive functioning of children with SLI were rated significantly worse than those of controls by both parents and teachers. Adults' perceptions of the children's executive functioning significantly correlated with the children's language abilities. Parent and teacher perceptions of executive functioning in children with SLI align with prior findings of executive deficits that have been documented on neuropsychological assessments and experimental tasks. Furthermore, the results provide additional supporting evidence of the relationship between language abilities and executive functioning in early child development.

This investigation examined mediators of the longitudinal relation between negative affectivity and the development of problematic drinking behavior in adolescent boys and girls. In the present study, 499 early adolescents completed inventories of negative affectivity, attitudes toward delinquency, personal delinquency, and affiliation with delinquent peers. Positive attitudes toward delinquency emerged as the most consistent mediator and strongly predicted drinking frequency in various situations. Compared with personal delinquency, both attitudes toward delinquency and peer delinquency were superior predictors of affect-related drinking. Our results also demonstrated that positive attitudes toward delinquency mediated the relation between negative affectivity and later development of an alcohol use disorder. These findings suggest that a proneness to unpleasant affect impacts adolescent drinking by heightening risk for general rejection of normative behavior, rather than by increasing drinking as a means of managing affect. The importance and implications of testing delinquency variables together in the same model are discussed. PMID:17490823

To compare the outcomes among war veterans who pray/do not pray and who were not suffering mental disorders after the Bosnia-Herzegovina war (1992-95). The sample consists of 100 healthy Bosnian war veterans divided in two equal groups-one, a highly religious group inside which were individuals who perform five obligatory prayers every day, and another group of individuals who do not practice any daily prayer. We used Minnesota Multiphase Personal Inventory (MMPI), Profile Index of Emotions (PIE) and Life Style Questionnaire (LSQ). War veterans who prayed had significantly higher levels for: incorporation, self-protection, and for reactive formation; but significantly lower levels for regression, compensation, transfer, no-controlling, oppositional and aggressiveness than their peers who did not pray. Practicing religion (regular performing daily prayers) is associated with reduction of tendencies towards the tendency for risk, impulsiveness, and aggression. It is also associated with successful overcoming of emotional conflicts in war veterans who practiced religion than their peers who did not practice religion.

The current study investigated the relationship between parental attachment and depressive symptoms as well as the mediating effect of self-control in two different cultures. Samples were 1305 Chinese and 1327 Italian adolescents. They completed the Inventory of Parental and Peer Attachment, the Self-Restraint Subscale of the Adolescents' Self-Consciousness Scale, and the Children's Depression Inventory that assessed parental attachment, self-control, and depressive symptoms, respectively. Results showed that: (1) Few cultural differences in depressive symptom were observed. (2) Parental attachment and self-control were negatively related to depressive symptoms in both cultures. (3) Self-control mediated the relations between parental attachment and depressive symptoms in both cultures. (4) The direct and indirect effects were invariant across cultures. In conclusion, parental attachment and self-control are important for adolescents' depressive symptoms in Chinese and Italian adolescents.

In this study we analyzed the etiology of the relationship between personality traits and retrospectively recalled family environment. The data of 226 identical and 168 fraternal twin pairs reared together from the Jena twin study of social attitudes were available. Personality traits were measured using the self- and peer report versions of the German NEO-personality inventory-revised. A German version of Blocks Environmental Questionnaire was applied to measure two broad dimensions of the family environment retrospectively: support and organization. We could replicate earlier findings that retrospective reports of these family environment dimensions were in part genetically influenced. A total of 66% of the genetic variance in support and 24% in organization could be accounted for by heritable variance in self-rated personality. That was replicated by using peer reports of personality, 41% explained genetic variance in support and 17% in organization. Environmental mediations were negligible. This indicates that the relationship between personality and retrospectively recalled family environment is largely genetically mediated.

Heavy episodic drinking is common among college students and remains a serious public health issue. Previous event-level research among college students has examined behaviors and individual-level characteristics that drive consumption and related consequences but often ignores the social network of people with whom these heavy drinking episodes occur. The main aim of the current study was to investigate the network of social connections between drinkers on their heaviest drinking occasions. Sociocentric network methods were used to collect information from individuals in the first-year class (N=1342) at one university. Past-month drinkers (N=972) reported on the characteristics of their heaviest drinking occasion in the past month and indicated who else among their network connections was present during this occasion. Average max drinking day indegree, or the total number of times a participant was nominated as being present on another students' heaviest drinking occasion, was 2.50 (SD=2.05). Network autocorrelation models indicated that max drinking day indegree (e.g., popularity on heaviest drinking occassions) and peers' number of drinks on their own maximum drinking occasions were significantly associated with participant maximum number of drinks, after controlling for demographic variables, pregaming, and global network indegree (e.g., popularity in the entire first-year class). Being present at other peers' heaviest drinking occasions is associated with greater drinking quantities on one's own heaviest drinking occasion. These findings suggest the potential for interventions that target peer influences within close social networks of drinkers. Copyright © 2017 Elsevier Ltd. All rights reserved.

Purpose The purpose of this study was to develop and test the feasibility of a parent-to-parent support intervention for parents whose child has recently been diagnosed with type 1 diabetes in the United Kingdom. Methods The research team conducted a formative evaluation, working with parents to design an individual-level parent-to-parent support intervention. Issues of recruitment, uptake, attrition, pattern of contact, and intervention acceptability were assessed. Results A US program was adapted in collaboration with a parents’ advisory group. Of 19 parents nominated as potential mentors by their pediatric diabetes specialist nurses, 12 (63%) volunteered and 11 continued for the 12-month intervention period. Thirty-three children were diagnosed with diabetes in the study period, with 25 families eligible to participate as recipients of the intervention; 9 parents from 7 of those families participated, representing 28% of those eligible. Feedback from parents and clinic staff identified peer support as a welcome service. Lessons were learned about the nature of the supporting relationship (eg, proximity, connectedness, and managing endings) that will enhance the design of future peer support programs. Conclusions Parent-to-parent support in the context of newly diagnosed childhood diabetes in the United Kingdom is feasible to deliver, with good engagement of mentors and clinic staff. The program was acceptable to parents who chose to participate, although uptake by parents whose child had been recently diagnosed was lower than expected. The results merit further investigation, including exploration of parent preference in relation to peer support. PMID:27099255

This study uses intraindividual variability and change methods to test theoretical accounts of self-concept and its change across time and context, and the developmental implications of this variability. The five-year longitudinal study of 541 youth in a rural Pennsylvania community from 3rd through 7th grade included twice-yearly assessments of self-concept (academic and social), corresponding external evaluations of competence (e.g., teacher-rated academic skills, peer-nominated “likeability”), and multiple measures of youths' overall adjustment. Multiphase growth models replicate previous research, suggesting significant decline in academic self-concept during middle school, but modest growth in social self-concept from 3rd through 7th grade. Next, a new contribution is made to the literature by quantifying the amount of within-person variability (i.e., “lability”) around these linear self-concept trajectories as a between-person characteristic. Self-concept lability was found to associate with a general profile of poorer competence and adjustment, and to predict poorer academic and social competence at the end of 7th grade above and beyond level of self-concept. Finally, there was substantial evidence that wave-to-wave changes in youths' self-concepts correspond to teacher and peer evaluations of youths' competence, that attention to peer feedback may be particularly strong during middle school, and that these relations may be moderated by between-person indicators of youths' general adjustment. Overall, findings highlight the utility of methods sensitive to within-person variation for clarifying the dynamics of youths' self-system development. PMID:21928883

There has been limited research exploring the similarity of perception of friendship quality between children with Autism Spectrum Disorder (ASD) and their friends. In this study, 45 children with ASD participated together with their friends. Two levels of friendship quality congruency were investigated: reciprocity and mutuality. A high proportion of the friendships were reciprocated for both the mixed and non-mixed friendship groups. Nevertheless, students with ASD reported substantial differences in perceptions of their friendship quality as compared to their nominated friends. The findings of the present study mirrored those of previous research with typically developing children. Further study is required to systematically investigate the differences in friendship quality perceptions within friendship dyads for both typically developing children and those with ASD diagnosis.

Using data from two American and one Finnish long-term longitudinal studies, we examined continuity of general aggression from age 8 to physical aggression in early adulthood (age 21–30) and whether continuity of aggression differed by country, sex, and parent occupational status. In all samples, childhood aggression was assessed via peer nominations and early adulthood aggression via self-reports. Multi-group structural equation models revealed significant continuity in aggression in the American samples but not in the Finnish sample. These relations did not differ by sex but did differ by parent occupational status: whereas there was no significant continuity among American children from professional family-of-origin backgrounds, there was significant continuity among American children from non-professional backgrounds.

Most Likely to Succeed: Long-Run Returns to Adolescent Popularity
Shi, Ying; Moody, James
2016-01-01
Sociological explanations for economic success tend toward measures of embeddedness in longstanding social institutions, such as race and gender, or personal skills represented mainly by educational attainment. In this paper we seek a distinctively social foundation for success by investigating the long-term association between high school popularity and income. Using rich longitudinal data, we find a clear and persistent association between the number of friendship nominations received and adult income, even after accounting for the mediating influences of diverse personal, family, and work characteristics. This skill is distinct from conventional personality measures such as the Big Five, and persists long into adulthood. We hypothesize that popularity encapsulates a socioemotional skill recognized by peers as the practice of being a good friend rather than an indicator of social status. PMID:28439525

This paper introduces new longitudinal network data from the “Promoting School-Community-University Partnerships to Enhance Resilience” or “PROSPER” peers project. In 28 communities, grade-level sociometric friendship nominations were collected from two cohorts of middle school students as they moved from 6th, to 9th grade. As an illustration and description of these longitudinal network data, this paper describes the school popularity structure, changes in popularity position, and suggests linkages between popularity trajectory and substance use. In the cross-section, we find that the network is consistent with a hierarchical social organization, but exhibits considerable relational change in both particular friends and position at the individual level. We find that both the base level of popularity and the variability of popularity trajectories effect substance use. PMID:21765588
Application of Recommended Design Practices for Conceptual Nuclear Fusion Space Propulsion Systems
NASA Technical Reports Server (NTRS)
Williams, Craig H.
2004-01-01
An AIAA Special Project Report was recently produced by AIAA's Nuclear and Future Flight Propulsion Technical Committee and is currently in peer review. The Report provides recommended design practices for conceptual engineering studies of nuclear fusion space propulsion systems. Discussion and recommendations are made on key topics including design reference missions, degree of technological extrapolation and concomitant risk, thoroughness in calculating mass properties (nominal mass properties, weight-growth contingency and propellant margins, and specific impulse), and thoroughness in calculating power generation and usage (power-flow, power contingencies, specific power). The report represents a general consensus of the nuclear fusion space propulsion system conceptual design community and proposes 15 recommendations. This paper expands on the Report by providing specific examples illustrating how to apply each of the recommendations.

The 2008-2009 Task Force for the Recognition of Teaching Excellence was charged by the AACP Council of Faculties Leadership to examine teaching excellence by collecting best practices from colleges and schools of pharmacy, evaluating the literature to identify evidence-based criteria for excellent teaching, and recommending appropriate means to acknowledge and reward teaching excellence. This report defines teaching excellence and discusses a variety of ways to assess it, including student, alumni, peer, and self-assessment. The task force identifies important considerations that colleges and schools must address when establishing teaching recognition programs including the purpose, criteria, number and mix of awards, frequency, type of award, and method of nominating and determining awardees. The report concludes with recommendations for the academy to consider when establishing and revising teaching award programs. PMID:21301598

The aim of this study was to analyze the relationship between sociometric types, behavioral categories, and academic self-concept in a sample of 1,349 (51.7% boys) Spanish adolescents, ranging in age from 12 to 16 years. the students’ sociometric nomination was performed using the Programa Socio (Partner Program), and academic self-concept was measured with the Self Description Questionnaire (SDQ-II; Marsh, 1992). results show that academic self-concept was a significant predictor of sociometric types and behavioral categories, as students with high scores on academic self-concept were more likely to be positively rated by their peers (popular, leaders, collaborators and good students) than students with low scores on student academic self-concept. these results reinforce the emphasis on academic self-concept research and its relevance to educational practice.
Associations between facial emotion recognition and young adolescents’ behaviors in bullying
Gini, Gianluca; Altoè, Gianmarco
2017-01-01
This study investigated whether different behaviors young adolescents can act during bullying episodes were associated with their ability to recognize morphed facial expressions of the six basic emotions, expressed at high and low intensity. The sample included 117 middle-school students (45.3% girls; mean age = 12.4 years) who filled in a peer nomination questionnaire and individually performed a computerized emotion recognition task. Bayesian generalized mixed-effects models showed a complex picture, in which type and intensity of emotions, students’ behavior and gender interacted in explaining recognition accuracy. Results were discussed with a particular focus on negative emotions and suggesting a “neutral” nature of emotion recognition ability, which does not necessarily lead to moral behavior but can also be used for pursuing immoral goals.

This study examines the independent impact of bullying on suicide risk. Bullying was assessed by peer nomination in a prospective study of 1,655 7th and 8th grade Korean students, and suicide by youth self-report. Odds Ratios (ORs) of bullying for suicidal risks were computed, controlling for other suicide risk factors. Victim-Perpetrators and female Victims at baseline showed increased risk for persistent suicidality (OR: 2.4-9.8). Male Incident Victims exhibited increased risk for suicidal behaviors and ideations (OR = 4.4, 3.6). Female Persistent Perpetrators exhibited increased risks for suicidal behaviors; male Incident Perpetrators had increased risk for suicidal ideations (OR = 2.7, 2.3). Baseline-only male Victim-Perpetrators showed increased risk for suicidal ideations. (OR = 6.4). Bullying independently increased suicide risks.
Women and botany in Risorgimento Italy.
Logan, Gabriella Berti
2004-01-01
The first Italian women described as botanists by their male peers were active during the Risorgimento. They were few in numbers and only one of them, Elisabetta Fiorini, was recognized for her extensive contributions to the field of cryptogams in Italy by being nominated to important Italian scientific academies. No such recognition was ever alloted to the other female botanists who acted as collectors, correspondents and/or patrons to male botanists, had their own garden of exotic plants, or discovered a new species of phanerogams, and occasionally published on the subject. This study will show that a woman could still belong to Italian scientific academies in the nineteenth century, if like Fiorini, she chose to practice science in a way that was considered at par with that of male scientists.

In our study we investigated whether there is a relation between the degree of discontent in relations with the proximal social environment (family and peer groups) and adolescent personality features. The study was conducted on a statistical representative and homogenous sample consisting of 2908 teenagers (51.5% girls and 48.5 % boys, aged between 15 and 19 years). It was an observational (case) study and it consisted in 2 questionnaires applying: Freiburg Personality Inventory (212 items) and CORT 2004 questionnaire (116 items, 6 referring to the discontent levels created by proximal social environment). Cronbach's alpha index was 0.802 for FPI and 0,910 for CORT 2004. Statistical analysis was performed by SPSS 16 program applying Chi square (χ2) and gamma (γ) correlation. Depression and Emotional lability correlated positively and powerfully with q15 (discontent degree of relations with present friend-peers) (γ = 0.471, Sig. 0.000, and γ = 0.383, Sig. 0.000, respectively) and q5 (discontent degree of the relation with parents) (γ = 0.380, Sig. 0.000, and γ = 0.337, Sig. 0.000, respectively). Sociability and calm correlated negative with q5 (γ = -0.14, Sig. 0.000, and γ = -0.35, Sig. 0.000, respectively), q15 (γ = -0.33, Sig. 000 and γ = -0.18, Sig. 000, respectively). In conclusion, there is direct proportional relation between the discontent degree of relations with friend-peers and parents and depression and emotional lability, and inverse proportional relation of friend-peers and parents with sociability and calm.

Abstract Background: Previous research has paid little to no attention towards exploring methods of identifying existing medical student leaders. Aim: Focusing on the role of influence and employing the tenets of the engaging leadership model, this study examines demographic and academic performance-related differences of positive influencers and if students who have been peer-identified as positive influencers also demonstrate high levels of genuine concern for others. Methods: Three separate fourth-year classes were asked to designate classmates that had significant positive influences on their professional and personal development. The top 10% of those students receiving positive influence nominations were compared with the other students on demographics, academic performance, and genuine concern for others. Results: Besides age, no demographic differences were found between positive influencers and other students. High positive influencers were not found to have higher standardized exam scores but did receive significantly higher clinical clerkship ratings. High positive influencers were found to possess a higher degree of genuine concern for others. Conclusion: The findings lend support to (a) utilizing the engaging model to explore leaders and leadership within medical education, (b) this particular method of identifying existing medical student leaders, and (c) return the focus of leadership research to the power of influence.
Empathy in adolescence: Relations with emotion awareness and social roles.
Rieffe, Carolien; Camodeca, Marina
2016-09-01
In this study, we aimed at gaining a better understanding of the individual differences contributing to feelings of empathy in adolescents. Therefore, we examined the extent to which emotion awareness (e.g., recognizing and appreciating one's own and the emotions of others) and a tendency for certain social roles (e.g., helping or teasing peers when being bullied) are related to adolescents' levels of empathy. The sample was comprised of 182 adolescents aged between 11 and 16. Empathy and emotion awareness were assessed using self-report measures. Peer reports were used to indicate adolescents' different social roles: Bullying, defending the victim, and outsider behaviour. Outcomes demonstrated that evaluating one's own and the emotions of others, and more defending nominations were associated with both affective and cognitive empathy, whereas aspects of emotion awareness which are linked with internalizing symptoms were related to empathic distress, suggesting maladaptive emotion appraisal. Furthermore, outsider behaviour was associated with empathic distress, emphasizing a self-focused orientation. In contrast, more bullying was negatively associated with cognitive empathy. Overall, these outcomes demonstrate that, besides social roles, emotion awareness is an important factor for adaptive empathic reactions, whereas emotion dysregulation might cause distress when witnessing the negative feelings of others. © 2016 The British Psychological Society.

This report summarizes the results of the Asia-Pacific Metrology Programme (APMP) supplementary comparison APMP.M.P-S5 for hydraulic gauge pressure in the range of 1 MPa to 10 MPa, which is a bilateral comparison carried out at the National Institute of Metrology, China (NIM) and the Physikalisch-Technische Bundesanstalt, Germany (PTB) during the period June 2014 to June 2015. NIM piloted the comparison and provided the transfer standard, which was a piston-cylinder assembly (PCA) of 1 cm2 nominal effective area built in a hydraulic pressure balance manufactured by Fluke Corporation. The laboratory standards of NIM and PTB are both hydraulic pressure balances equipped with PCAs, of which the nominal effective area is 1 cm2 for NIM and 5 cm2 for PTB. The results of the comparison successfully demonstrated that the hydraulic gauge pressure standards of NIM and PTB in the range of 1 MPa to 10 MPa are equivalent within their claimed uncertainties.

Training public health superheroes: five talents for public health leadership.
Day, Matthew; Shickle, Darren; Smith, Kevin; Zakariasen, Ken; Moskol, Jacob; Oliver, Thomas
2014-12-01
Public health leaders have been criticized for their policy stances, relationships with governments and failure to train the next generation. New approaches to the identification and training of public health leaders may be required. To inform these, lessons can be drawn from public health 'superheroes'; public health leaders perceived to be the most admired and effective by their peers. Members and Fellows of the UK Faculty of Public Health were contacted via e-newsletter and magazine and asked to nominate their 'Public Health Superhero'. Twenty-six responses were received, nominating 40 different people. Twelve semi-structured interviews were conducted. Thematic analysis, based on 'grounded theory', was conducted. Five leadership 'talents' for public health were identified: mentoring-nurturing, shaping-organizing, networking-connecting, knowing-interpreting and advocating-impacting. Talent-based approaches have been effective for leadership development in other sectors. These talents are the first specific to the practice of public health and align with some aspects of existing frameworks. An increased focus on identifying and developing talents during public health training, as opposed to 'competency'-based approaches, may be effective in strengthening public health leadership. Further research to understand the combination and intensity of talents across a larger sample of public health leaders is required. © The Author 2014.

To identify critical emergency medicine-focused firearm injury research questions and develop an evidence-based research agenda. National content experts were recruited to a technical advisory group for the American College of Emergency Physicians Research Committee. Nominal group technique was used to identify research questions by consensus. The technical advisory group decided to focus on 5 widely accepted categorizations of firearm injury. Subgroups conducted literature reviews on each topic and developed preliminary lists of emergency medicine-relevant research questions. In-person meetings and conference calls were held to iteratively refine the extensive list of research questions, following nominal group technique guidelines. Feedback from external stakeholders was reviewed and integrated. Fifty-nine final emergency medicine-relevant research questions were identified, including questions that cut across all firearm injury topics and questions specific to self-directed violence (suicide and attempted suicide), intimate partner violence, peer (nonpartner) violence, mass violence, and unintentional ("accidental") injury. Some questions could be addressed through research conducted in emergency departments; others would require work in other settings. The technical advisory group identified key emergency medicine-relevant firearm injury research questions. Emergency medicine-specific data are limited for most of these questions. Funders and researchers should consider increasing their attention to firearm injury prevention and control, particularly to the questions identified here and in other recently developed research agendas.

Investigating the Relationship between Need for Cognition and Skill in Ethical Hackers
DOE Office of Scientific and Technical Information (OSTI.GOV)
Le Blanc, Katya; Freeman, Sarah
As technology gets more complex and increasingly connected, there is an increasing concern with cyber security. There is also a growing demand for cyber security professionals. Unfortunately there currently are not enough skilled professionals to meet that demand. In order to prepare the next generation of cyber security professionals to meet this demand, we need to understand what characteristics make skilled cyber security professionals. For this work, we focus on professionals who take an offensive approach to cyber security, so called ethical hackers. These hackers utilize many of the same skills that the adversaries that we defend against would use,more » with the goal of identifying vulnerabilities and address them before they are exploited by adversaries. A commonly held belief among ethical hackers is that hackers must possess exceptional curiosity and problem solving skills in order to be successful. Curiosity is has been studied extensively in psychology, but there is no consensus on what it is and how to measure it. Further, many existing inventories for assessing curiosity are targeted at measuring curiosity in children. Although there isn’t an accepted standard to assess curiosity in adults, a related construct, called Need for Cognition (may capture what is meant when people speak of curiosity. The Need for Cognition scale also captures the tendency toward preferring complex problems (which correlates with good problem solving skills), which may provide insight into what make skilled hackers. In addition to the Need for Cognition, we used a structured interview to assess hacker skill. Hackers rated their own skill on a scale from one to ten on a predefined list of hacker skills. They were then asked to rate a peer who they felt was most skilled in each of the skills. They were asked to rate two peers for each skill, one that they worked with directly and one person that was the most skilled in the field (these could be known by reputation only). The hypothesis is that hackers have a higher than average (i.e., compared to non-hackers) Need for cognition and that Need for Cognition will be positively correlated with self-reported and peer reported skill. We interviewed 20 cyber security researchers who specialize in offensive approaches. Based on the responses to the hacker skill inventory, we generated a self-reported skill score for each participant. We also developed a peer-rating for each participant based on the number of times each individual that was interviewed was named as the most skilled in a particular area. The results indicate that the sample of ethical hackers has a high Need for Cognition and that Need for cognition was related to both self-reported skill and peer-reported skill. The results are discussed in the context of training and recruitment of cyber security professionals.« less

This study aimed to (1) evaluate the gap filling skills and reading mistakes of students with cochlear implants, and to (2) compare their results with those of their normal-hearing peers. The effects of implantation age and total time of cochlear implant use were analyzed in relation to the subjects' reading skills development. The study included 19 students who underwent cochlear implantation and 20 students with normal hearing, who were enrolled at the 6th to 8th grades. The subjects' ages ranged between 12 and 14 years old. Their reading skills were evaluated by using the Informal Reading Inventory. A significant relationship were found between implanted and normal-hearing students in terms of the percentages of reading error and the percentages of gap filling scores. The average order of the reading errors of students using cochlear implants was higher than that of normal-hearing students. As for the gap filling, the performances of implanted students in the passage are lower than those of their normal-hearing peers. No significant relationship was found between the variables tested in terms of age and duration of implantation on the reading performances of implanted students. Even if they were early implanted, there were significant differences in the reading performances of implanted students compared with those of their normal-hearing peers in older classes.

As a result of their hearing loss, adults with cochlear implants (CIs) would self-report poorer executive functioning (EF) skills than normal-hearing (NH) peers, and these EF skills would be associated with performance on speech recognition tasks. EF refers to a group of high order neurocognitive skills responsible for behavioral and emotional regulation during goal-directed activity, and EF has been found to be poorer in children with CIs than their NH age-matched peers. Moreover, there is increasing evidence that neurocognitive skills, including some EF skills, contribute to the ability to recognize speech through a CI. Thirty postlingually deafened adults with CIs and 42 age-matched NH adults were enrolled. Participants and their spouses or significant others (informants) completed well-validated self-reports or informant-reports of EF, the Behavior Rating Inventory of Executive Function - Adult (BRIEF-A). CI users' speech recognition skills were assessed in quiet using several measures of sentence recognition. NH peers were tested for recognition of noise-vocoded versions of the same speech stimuli. CI users self-reported difficulty on EF tasks of shifting and task monitoring. In CI users, measures of speech recognition correlated with several self-reported EF skills. The present findings provide further evidence that neurocognitive factors, including specific EF skills, may decline in association with hearing loss, and that some of these EF skills contribute to speech processing under degraded listening conditions.
Parent ratings of executive functioning in children with shunted hydrocephalus.

The present study examined the executive functioning of a group of children with a history of communicating hydrocephalus and how their level of functioning was correlated with parent ratings of executive functioning. The study examined the executive functioning of 39 shunted children with a history of hydrocephalus and 20 healthy peers. Additionally, parents of both groups of children completed the Behavior Rating Inventory of Executive Function (BRIEF) to assess the parents' perceptions of their children's executive functioning. Finally, the study investigated the relationship between the shunted hydrocephalus children's executive functioning and the parent ratings of their executive functioning. Overall, the children with a history of shunted hydrocephalus displayed more executive dysfunction than their healthy peers. These children were rated by their parents as having more executive dysfunction than their healthy peers and displaying working memory, initiation, mental flexibility and self-monitoring difficulties, which appear to increase with age among the shunted hydrocephalus group. While parent ratings as measured by the BRIEF indices did not correlate with all executive tasks within the shunted hydrocephalus group, the cognitive tests assessing mental flexibility may be sensitive to the problems noted by parents at home. The children with a history of shunted hydrocephalus displayed executive functioning deficits on formal examination. The parents of children with a history of shunted hydrocephalus report ongoing executive difficulties which may increase with age. Copyright © 2012 S. Karger AG, Basel.
Using Second Life to Facilitate Peer Storytelling for Grieving Oncology Nurses

Background Oncology nurses often experience intense emotional reactions to patient deaths but may be forced to ignore or hide their feelings because of work-related responsibilities. The complexity of nurses' work and personal lives creates obstacles for participating in traditional support groups where grieving nurses can bond and share. We hypothesized that using a web-based, three-dimensional (3-D) virtual world technology (Second Life) may provide a venue to facilitate peer storytelling to support nurses dealing with grief. Methods We used a mixed-methods approach involving focus groups and surveys to explore the use of peer storytelling for grieving oncology nurses. Nine acute and ambulatory oncology nurses in groups of 3 participated using avatars in 5 group moderator-guided sessions lasting 1 hour each in a private 3-D outdoor virtual meeting space within Second Life. Baseline information was collected using a 12-item demographic and professional loss survey. At the end of the study, a 20-item survey was administered to measure professional losses during the study, exchange of support during sessions, and meaning-making and to evaluate peer storytelling using Second Life. Results Overall, nurses reported peer storytelling sessions in Second Life were helpful in making sense of and in identifying a benefit of their grief experience. They felt supported by both the group moderator and group members and were able to personally support group members during storytelling. Although nurses reported Second Life was helpful in facilitating storytelling sessions and expressed overall satisfaction with using Second Life, open-ended comments registered difficulties encountered, mostly with technology. Three central themes emerged in sessions, representing a dynamic relationship between mental, spiritual, and emotional-behavioral responses to grief: cognitive readiness to learn about death, death really takes death experience, and emotional resilience. Conclusion This study suggests a potential benefit in using peer storytelling sessions in Second Life to facilitate oncology nurses' grief resolution. In particular, Second Life provides a nonthreatening venue for participating nurses to share their innermost feelings and accrue their own inventory of stories. Through these stories, each nurse's relational experience in expressing and coping with grief is realized. PMID:25598720

To evaluate the effectiveness of telephone based peer support in the prevention of postnatal depression. Multisite randomised controlled trial. Seven health regions across Ontario, Canada. 701 women in the first two weeks postpartum identified as high risk for postnatal depression with the Edinburgh postnatal depression scale and randomised with an internet based randomisation service. Proactive individualised telephone based peer (mother to mother) support, initiated within 48-72 hours of randomisation, provided by a volunteer recruited from the community who had previously experienced and recovered from self reported postnatal depression and attended a four hour training session. Edinburgh postnatal depression scale, structured clinical interview-depression, state-trait anxiety inventory, UCLA loneliness scale, and use of health services. After web based screening of 21 470 women, 701 (72%) eligible mothers were recruited. A blinded research nurse followed up more than 85% by telephone, including 613 at 12 weeks and 600 at 24 weeks postpartum. At 12 weeks, 14% (40/297) of women in the intervention group and 25% (78/315) in the control group had an Edinburgh postnatal depression scale score >12 (chi(2)=12.5, P<0.001; number need to treat 8.8, 95% confidence interval 5.9 to 19.6; relative risk reduction 0.46, 95% confidence interval 0.24 to 0.62). There was a positive trend in favour of the intervention group for maternal anxiety but not loneliness or use of health services. For ethical reasons, participants identified with clinical depression at 12 weeks were referred for treatment, resulting in no differences between groups at 24 weeks. Of the 221 women in the intervention group who received and evaluated their experience of peer support, over 80% were satisfied and would recommend this support to a friend. Telephone based peer support can be effective in preventing postnatal depression among women at high risk. ISRCTN 68337727.

Inflated Applicants: Attribution Errors in Performance Evaluation by Professionals
Swift, Samuel A.; Moore, Don A.; Sharek, Zachariah S.; Gino, Francesca
2013-01-01
When explaining others' behaviors, achievements, and failures, it is common for people to attribute too much influence to disposition and too little influence to structural and situational factors. We examine whether this tendency leads even experienced professionals to make systematic mistakes in their selection decisions, favoring alumni from academic institutions with high grade distributions and employees from forgiving business environments. We find that candidates benefiting from favorable situations are more likely to be admitted and promoted than their equivalently skilled peers. The results suggest that decision-makers take high nominal performance as evidence of high ability and do not discount it by the ease with which it was achieved. These results clarify our understanding of the correspondence bias using evidence from both archival studies and experiments with experienced professionals. We discuss implications for both admissions and personnel selection practices. PMID:23894437

A disputed social status among peers puts children and adolescents at risk for developing a wide range of problems, such as being bullied. However, there is a lack of knowledge about which early predictors could be used to identify (young) adolescents at risk for a disputed social status. The aim of this study was to assess whether preventive child health care (PCH) findings on early childhood predict neglected and rejected status in early adolescence in a large longitudinal community-based sample. Data came from 898 participants who participated in TRAILS, a longitudinal study. Information on early childhood factors was extracted from the charts of routine PCH visits registered between infancy and age of 4 years. To assess social status, peer nominations were used at age of 10-12 years. Multinomial logistic regression showed that children who had a low birth weight, motor problems, and sleep problems; children of parents with a low educational level (odds ratios [ORs] between 1.71 and 2.90); and those with fewer attention hyperactivity problems (ORs = .43) were more likely to have a neglected status in early adolescence. Boys, children of parents with a low educational level, and children with early externalizing problems were more likely to have a rejected status in early adolescence (ORs between 1.69 and 2.56). PCH findings on early childhood-on motor and social development-are predictive of a neglected and a rejected status in early adolescence. PCH is a good setting to monitor risk factors that predict the social status of young adolescents. Copyright © 2012 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

Conceptualization and Assessment of Hypersexual Disorder: A Systematic Review of the Literature.
Montgomery-Graham, Stephanie
2017-04-01
Despite the rejection of hypersexual disorder (HD) as a new diagnosis in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), clinical and research interest in HD continues. To systematically review the existing scientific literature on the conceptualization and assessment of HD and out-of-control sexual behavior. Studies were identified from PsychInfo, PubMed, JSTOR, Google Scholar, and Scholar's Portal using an exhaustive list of key terms. Of 299 total articles identified and screened, 252 were excluded, and 47 are included in this review. To review two categories of articles: HD conceptualization and HD psychometric assessment. First, results of the review of theoretical conceptualizations of HD reflected a large proportion of the peer-reviewed literature devoted to discussing conceptualizations of HD without reaching consensus. Second, results of the review of HD psychometric assessments were analyzed using Hunsley and Mash's (2008) criteria to evaluate psychometric adequacy of evidence-based assessment measurements. The six most researched measurements of HD were evaluated, including the Hypersexual Disorder Screening Inventory, the Hypersexual Behavior Inventory, the Sexual Compulsivity Scale, the Sexual Addiction Screening Test, the Sexual Addiction Screening Test-Revised, and the Compulsive Sexual Behavior Inventory. Psychometric properties of the scales are reviewed, evaluated, and discussed. The Hypersexual Disorder Screening Inventory, the measurement proposed for the clinical screening of HD by the DSM-5 workgroup, currently has the strongest psychometric support. Future research and clinical directions are discussed in light of findings after the literature review and synthesis. Montgomery-Graham S.

The objective of the present study was to examine the effects of aggression and conflict-managing skills on popularity and attitude to school in Russian adolescents. Three types of aggression (physical, verbal, and indirect), constructive conflict resolution, third-party intervention, withdrawal, and victimization were examined using the Peer-Estimated Conflict Behavior (PECOBE) inventory [Bjorkquist and Osterman, 1998]. Also, all respondents rated peer and self-popularity with same-sex classmates and personal attitude to school. The sample consisted of 212 Russian adolescents (101 boys, 111 girls) aged between 11 and 15 years. The findings attest to significant sex differences in aggression and conflict resolution patterns. Boys scored higher on physical and verbal aggression, and girls on indirect aggression. Girls were socially more skillful than boys in the use of peaceful means of conflict resolution (they scored higher on constructive conflict resolution and third-party intervention). The attributional discrepancy index (ADI) scores were negative for all three types of aggression in both sexes. Verbal aggression is apparently more condemned in boys than in girls. ADI scores were positive for constructive conflict resolution and third-party intervention in both genders, being higher in boys. In girls, verbal aggression was positively correlated with popularity. In both sexes, popularity showed a positive correlation with constructive conflict resolution and third-party intervention, and a negative correlation with withdrawal and victimization. Boys who liked school were popular with same-sex peers and scored higher on constructive conflict resolution. Girls who liked school were less aggressive according to peer rating. They also rated higher on conflict resolution and third-party intervention. Physical aggression was related to age. The results are discussed in a cross-cultural perspective.

Creative people have been found to score higher on psychopathologic scales in standardized tests, particularly on the scales that measure traits of psychoticism, and to be more likely to report an excess of nonright handedness compared with controls. However, results are inconsistent across surveys and methodologies, and the contribution of substance abuse has rarely been measured. In this study, 80 creative artists were compared with 80 matched noncreative controls on the Annett Hand Preference Questionnaire (HPQ), the Peters et al. Delusions Inventory, and the General Health Questionnaire. Creative artists were statistically more likely to admit the use of the left hand on the HPQ, with more widespread left hand use reported by artists involved in the creative activities traditionally associated with the right hemisphere (music and painting). They also scored higher on the Peters et al. Delusions Inventory independently from the level of psychopathology (measured with the General Health Questionnaire), from their laterality score (measured with the HPQ), and from their higher use of both licit and illicit drugs.
