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.

Even after evidence-based treatment, Attention-Deficit/Hyperactivity Disorder (ADHD) is associated with poor long-term outcomes. These outcomes may be partly explained by difficulties in peer functioning, which are common among children with ADHD and which do not respond optimally to standard ADHD treatments. We examined whether peer rejection and lack of dyadic friendships experienced by children with ADHD after treatment contribute to long-term emotional and behavioral problems and global impairment, and whether having a reciprocal friend buffers the negative effects of peer rejection. Children with Combined type ADHD (N=300) enrolled in the Multimodal Treatment Study of Children with ADHD (MTA) were followed for 8 years. Peer rejection and dyadic friendships were measured with sociometric assessments after the active treatment period (14 or 24 months after baseline; M ages 9.7 and 10.5 years, respectively). Outcomes included delinquency, depression, anxiety, substance use, and general impairment at 6 and 8 years after baseline (Mean ages 14.9 and 16.8 years, respectively). With inclusion of key covariates, including demographics, symptoms of ADHD, ODD, and CD, and level of the outcome variable at 24 months, peer rejection predicted cigarette smoking, delinquency, anxiety, and global impairment at 6 years and global impairment at 8 years after baseline. Having a reciprocal friend was not, however, uniquely predictive of any outcomes and did not reduce the negative effects of peer rejection. Evaluating and addressing peer rejection in treatment planning may be necessary to improve long-term outcomes in children with ADHD. PMID:22331455

Psychosocial Maladjustment at Student and Classroom Level as Indicators of Peer Victimization.

PubMed

Söderberg, Patrik; Korhonen, Johan; Björkqvist, Kaj

2017-10-01

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

Narrative representations of caregivers and emotion dysregulation as predictors of maltreated children's rejection by peers.

PubMed

Shields, A; Ryan, R M; Cicchetti, D

2001-05-01

This study examined whether maltreated children were more likely than nonmaltreated children to develop poor-quality representations of caregivers and whether these representations predicted children's rejection by peers. A narrative task assessing representations of mothers and fathers was administered to 76 maltreated and 45 nonmaltreated boys and girls (8-12 years old). Maltreated children's representations were more negative/constricted and less positive/coherent than those of nonmaltreated children. Maladaptive representations were associated with emotion dysregulation, aggression, and peer rejection, whereas positive/coherent representations were related to prosocial behavior and peer preference. Representations mediated maltreatment's effects on peer rejection in part by undermining emotion regulation. Findings suggest that representations of caregivers serve an important regulatory function in the peer relationships of at-risk children.

Social Risk and Peer Victimization in Elementary School Children: The Protective Role of Teacher-Student Relationships.

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

Minority acculturation and peer rejection: Costs of acculturation misfit with peer-group norms.

How do minority adolescents' personal acculturation preferences and peer norms of acculturation affect their social inclusion in school? Turkish and Moroccan minority adolescents (N = 681) reported their preferences for heritage culture maintenance, mainstream culture adoption, and their experiences of peer rejection as a key indicator of adjustment problems. Additionally, we aggregated peer acculturation norms of maintenance and adoption within ethnically diverse classrooms (N = 230 in 50 Belgian schools), distinguishing between co-ethnic (Turkish or Moroccan classmates only, N = 681) and cross-ethnic norms (also including N = 1,930 other classmates). Cross-ethnic peer-group norms (of adoption and maintenance) and co-ethnic norms (of maintenance, marginally) predicted minority experiences of peer rejection (controlling for ethnic composition). Moreover, misfit of minorities' own acculturation preferences with both cross-ethnic and co-ethnic peer-group norms was harmful. When cross-ethnic norms stressed adoption, 'integrationist' minority youth - who combined culture adoption with maintenance - experienced most peer rejection. Yet, when co-ethnic peers stressed maintenance, 'assimilationist' minority youth experienced most rejection. In conclusion, acculturation misfit with peer-group norms is a risk factor for minority inclusion in ethnically diverse environments. © 2016 The British Psychological Society.

Adolescent personality factors in self-ratings and peer nominations and their prediction of peer acceptance and peer rejection.

Scholte, R H; van Aken, M A; van Lieshout, C F

1997-12-01

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.

Gender and the Interplay of Source of Support and Peer Social Rejection on Internalizing Among Mexican American Youth

2017-01-01

Gendered interpersonal processes may explain the elevated rates of internalizing symptoms among adolescent girls relative to boys. Two such processes are peer social rejection and social support. The current study assessed for gender differences in the effect of 7th grade peer social rejection on 10th grade internalizing symptoms, as well as the moderating effects of social support from family and from friends in a sample of 749 (49% female) Mexican American adolescents, an understudied population with a unique social culture. Peer social rejection significantly predicted increased internalizing symptoms for girls. Although buffering effects of social support were not found, there were significant moderating effects of both sources of support for boys, such that at low levels of social support, peer social rejection was associated with decreased internalizing symptoms, and at high levels of social support, peer social rejection was associated with increased internalizing symptoms. The results help unpack the nuances of the interpersonal processes that lead to differential adjustment for adolescent boys and girls at this critical developmental stage. PMID:27739005

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.

Positively Biased Self-Perceptions of Peer Acceptance and Subtypes of Aggression in Children

Lynch, Rebecca J.; Kistner, Janet A.; Stephens, Haley F.; David-Ferdon, Corinne

2016-01-01

There is a growing body of research linking children’s positively biased self-perceptions with higher levels of aggression. This study extended this area of research by examining prospective associations of positively biased self-perceptions of peer acceptance with overt and relational aggression. In addition, moderating effects of peer rejection were examined to test the “disputed overestimation hypothesis,” which posits that the link between bias and aggression is limited to children who are rejected by their peers. Using a two-wave longitudinal design, measures of peer-rated and self-perceived peer acceptance and peer-rated overt and relational aggression were obtained for 712 children in 3rd through 5th grades (386 girls and 326 boys). Positively biased perceptions led to increases in relational, but not overt, aggression. This pattern was observed even when the effects of gender, race, peer rejection, and overt aggression on relational aggression were controlled. Contrary to the disputed overestimation hypothesis, the prospective associations between bias and aggression did not vary as a function of children’s peer rejection status, thus supporting the view that positive bias predicts future aggressive behavior, regardless of social status. The results are discussed in terms of the comparability with previous findings and practical implications. PMID:26423823

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

Predicting early adolescent gang involvement from middle school adaptation.

PubMed

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.

Young Children’s Affective Responses to Acceptance and Rejection From Peers: A Computer-based Task Sensitive to Variation in Temperamental Shyness and Gender

Howarth, Grace Z.; Guyer, Amanda E.; Pérez-Edgar, Koraly

2013-01-01

This study presents a novel task examining young children’s affective responses to evaluative feedback—specifically, social acceptance and rejection—from peers. We aimed to determine (1) whether young children report their affective responses to hypothetical peer evaluation predictably and consistently, and (2) whether young children’s responses to peer evaluation vary as a function of temperamental shyness and gender. Four- to seven-year-old children (N = 48) sorted pictures of unknown, similar-aged children into those with whom they wished or did not wish to play. Computerized peer evaluation later noted whether the pictured children were interested in a future playdate with participants. Participants then rated their affective responses to each acceptance or rejection event. Children were happy when accepted by children with whom they wanted to play, and disappointed when these children rejected them. Highly shy boys showed a wider range of responses to acceptance and rejection based on initial social interest, and may be particularly sensitive to both positive and negative evaluation. Overall, the playdate task captures individual differences in affective responses to evaluative peer feedback and is potentially amenable to future applications in research with young children, including pairings with psychophysiological measures.

The relation between social rejection and growth in antisocial behavior was investigated. In Study 1, 259 boys and girls (34% African American) were followed from Grades 1 to 3 (ages 6–8 years) to Grades 5 to 7 (ages 10–12 years). Early peer rejection predicted growth in aggression. In Study 2, 585 boys and girls (16% African American) were followed from kindergarten to Grade 3 (ages 5–8 years), and findings were replicated. Furthermore, early aggression moderated the effect of rejection, such that rejection exacerbated antisocial development only among children initially disposed toward aggression. In Study 3, social information-processing patterns measured in Study 1 were found to mediate partially the effect of early rejection on later aggression. In Study 4, processing patterns measured in Study 2 replicated the mediation effect. Findings are integrated into a recursive model of antisocial development. PMID:12705561

Negative parenting behavior and childhood oppositional defiant disorder: differential moderation by positive and negative peer regard.

Tung, Irene; Lee, Steve S

2014-01-01

Although negative parenting behavior and peer status are independently associated with childhood conduct problems (e.g., oppositional defiant disorder (ODD)), relatively little is known about their interplay, particularly in relation to differentiated measures of positive and negative peer regard. To improve the specificity of the association of negative parenting behavior and peer factors with ODD, we explored the potential interaction of parenting and peer status in a sample of 169 five-to ten-year-old ethnically diverse children with and without attention-deficit/hyperactivity disorder (ADHD) assessed using multiple measures (i.e., rating scales, interview) and informants (i.e., parents, teachers). Controlling for children's age, sex, number of ADHD symptoms, and parents' race-ethnicity, peer acceptance inversely predicted and inconsistent discipline, harsh punishment, and peer rejection were each positively associated with ODD symptom severity. Interactive influences were also evident such that inconsistent discipline and harsh punishment each predicted elevated ODD but only among children experiencing low peer acceptance or high peer rejection. These findings suggest that supportive environments, including peer acceptance, may protect children from negative outcomes associated with inconsistent discipline and harsh punishment. Findings are integrated with theories of social support, and we additionally consider implications for intervention and prevention. © 2013 Wiley Periodicals, Inc.

Depression in childhood and adolescence is often accompanied with social rejection by peers, which accentuates the course of that emotion. Despite the documented association between anger and depression, little is known about the impact of the interaction of both emotions on peer relations. The main objective of this study is to explore the interpersonal implications of depression with comorbid anger in a pediatric sample. The sample consisted of 466 participants; the mean age was 11.45 (SD = 1.55). There were 231 females (49.6 %) and 235 males (50.4 %). ANOVAs revealed significant differences between boys and girls in depression, aggression, anger experience/explosive anger and internalized responses to anger. There were no significant differences between the correlations computed with the data from boys and girls for the hypothesized associations among anger, aggression, depression, and peer acceptance/rejection. Both Anger-Out and Depression were significantly associated with perceived unpopularity. Additionally, the interaction of Anger-Out and Depression added significantly to the prediction of perceived unpopularity.

People are strongly motivated to feel accepted by others. Yet when faced with acute peer rejection they often aggress against the very peers they desire acceptance from, which may lead to further rejection. The present experiment tests three potential mediators of aggressive responses to acute peer rejection in the critical developmental stage of early adolescence. Participants (N=185, M(age)=11.5 years) completed personal profiles that were allegedly evaluated online by peers. After receiving negative or neutral peer feedback, participants could aggress against the same peers who had evaluated them. Rejected participants attributed more hostile intent to the peers, were angrier, showed a greater reduction in state self-esteem, and were more aggressive. Mediational analyses showed that hostile intent attributions mediated the acute peer rejection-aggression relationship, whereas increases in anger and decreases in state self-esteem did not. Thus, acute peer rejection evokes hostile intent attributions that, in turn, lead to aggressive reactions. © 2011 by the Society for Personality and Social Psychology, Inc

Neural responses to witnessing peer rejection after being socially excluded: fMRI as a window into adolescents’ emotional processing

PubMed Central

Masten, Carrie L.; Eisenberger, Naomi I.; Pfeifer, Jennifer H.; Dapretto, Mirella

2013-01-01

During adolescence, concerns about peer rejection and acceptance become increasingly common. Adolescents regularly experience peer rejection firsthand and witness these behaviors among their peers. In the current study, neuroimaging techniques were employed to conduct a preliminary investigation of the affective and cognitive processes involved in witnessing peer acceptance and rejection—specifically when these witnessed events occur in the immediate aftermath of a firsthand experience with rejection. During an fMRI scan, twenty-three adolescents underwent a simulated experience of firsthand peer rejection. Then, immediately following this experience they watched as another adolescent was ostensibly first accepted and then rejected. Findings indicated that in the immediate aftermath of being rejected by peers, adolescents displayed neural activity consistent with distress when they saw another peer being accepted, and neural activity consistent with emotion regulation and mentalizing (e.g., perspective-taking) processes when they saw another peer being rejected. Furthermore, individuals displaying a heightened sensitivity to firsthand rejection were more likely to show neural activity consistent with distress when observing a peer being accepted. Findings are discussed in terms of how witnessing others being accepted or rejected relates to adolescents’ interpretations of both firsthand and observed experiences with peers. Additionally, the potential impact that witnessed events might have on the broader perpetuation of bullying at this age is also considered. PMID:24033579

Rejected by peers-attracted to antisocial media content: rejection-based anger impairs moral judgment among adolescents.

2013-06-01

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

Predicting change in early adolescent problem behavior in the middle school years: a mesosystemic perspective on parenting and peer experiences.

PubMed

Véronneau, Marie-Hélène; Dishion, Thomas J

2010-11-01

The transition into middle school may be a risky period in early adolescence. In particular, friendships, peer status, and parental monitoring during this developmental period can influence the development of problem behavior. This study examined interrelationships among peer and parenting factors that predict changes in problem behavior over the middle school years. A longitudinal sample (580 boys, 698 girls) was assessed in Grades 6 and 8. Peer acceptance, peer rejection, and their interaction predicted increases in problem behavior. Having high-achieving friends predicted less problem behavior. Parental monitoring predicted less problem behavior in general, but also acted as a buffer for students who were most vulnerable to developing problem behavior on the basis of being well liked by some peers, and also disliked by several others. These findings highlight the importance of studying the family-peer mesosystem when considering risk and resilience in early adolescence, and when considering implications for intervention.

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.

A Developmental Perspective on Peer Rejection, Deviant Peer Affiliation, and Conduct Problems Among Youth.

PubMed

Chen, Diane; Drabick, Deborah A G; Burgers, Darcy E

2015-12-01

Peer rejection and deviant peer affiliation are linked consistently to the development and maintenance of conduct problems. Two proposed models may account for longitudinal relations among these peer processes and conduct problems: the (a) sequential mediation model, in which peer rejection in childhood and deviant peer affiliation in adolescence mediate the link between early externalizing behaviors and more serious adolescent conduct problems; and (b) parallel process model, in which peer rejection and deviant peer affiliation are considered independent processes that operate simultaneously to increment risk for conduct problems. In this review, we evaluate theoretical models and evidence for associations among conduct problems and (a) peer rejection and (b) deviant peer affiliation. We then consider support for the sequential mediation and parallel process models. Next, we propose an integrated model incorporating both the sequential mediation and parallel process models. Future research directions and implications for prevention and intervention efforts are discussed.

Developmental Processes in Peer Problems of Children with ADHD in the MTA Study1: Developmental Cascades and Vicious Cycles

2010-01-01

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

Problematic Peer Functioning in Girls with ADHD: A Systematic Literature Review.

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

This study evaluated whether positive and anger emotional frequency (the proportion of instances an emotion was observed) and intensity (the strength of an emotion when it was observed) uniquely predicted social relationships among kindergarteners (N = 301). Emotions were observed as naturally occurring at school in the fall term and multiple reporters (peers and teachers) provided information on quality of relationships with children in the spring term. In structural equation models, positive emotion frequency, but not positive emotion intensity, was positively related to peer acceptance and negatively related to peer rejection. In contrast, the frequency of anger provided unique positive prediction of teacher–student conflict and negative prediction of peer acceptance. Furthermore, anger intensity negatively predicted teacher–student closeness and positively predicted teacher–student conflict. Implications for promoting social relationships in school are discussed.

Parental punishment and peer victimization as developmental precursors to physical dating violence involvement among girls

PubMed Central

Hipwell, Alison E.; Stepp, Stephanie D.; Xiong, Shuangyan; Keenan, Kate; Blokland, Arjan; Loeber, Rolf

2012-01-01

The current study examined harsh punishment and peer victimization as developmental precursors to girls’ involvement in physical dating violence (PDV), and the putative mediating effect of rejection sensitivity. The sample comprised 475 African American and European American participants of the longitudinal Pittsburgh Girls Study who were dating at age 17. About 10% of girls reported significant perpetration and/or victimization of physical aggression in the relationship. Results showed that initial level and escalation in harsh punishment (between 10–13 years) and escalation in peer victimization (10–15 years) predicted PDV involvement, but this relationship was not mediated by rejection sensitivity. The results highlight the need to consider the impact of early experience of different forms of aggression on girls’ risk for PDV involvement. PMID:24591807

The role of attentional processes in children's prosocial behavior with peers: attention shifting and emotion.

PubMed

Wilson, Beverly J

2003-01-01

This study evaluated the role of attentional shifting in children's prosocial behavior with peers. Participants were 27 aggressive/rejected and 27 nonaggressive/popular kindergarten and first grade boys and girls. Children's ability to shift attention from one affective state to another was assessed during: (a) a computerized task that required shifting attention between different affective events (i.e., the Children's Attentional Shifting Task, CAST) and (b) an analogue entry task with unacquainted peers. Children's latency for sharing with peers was assessed after they experienced failure during the entry task. Aggressive/rejected children had significant difficulty shifting attention from negative to positive affect during the CAST and were slower to share after experiencing entry failure. In general, aggressive/rejected children were less able to regulate their behavior effectively after experiencing social failure. Girls, regardless of status, had less difficulty than boys shifting attention from one affective state to another during the CAST. In addition, children's social status/aggressiveness, their ability to regulate emotional behavior after social failure and to shift attention effectively on the CAST predicted approximately 31% of the variance in their latency to share. These findings suggest that the ability to shift attention between different affective states plays a significant role in children's prosocial behavior with peers.

The Role of Family for Youth Friendships: Examining a Social Anxiety Mechanism.

PubMed

Mak, Hio Wa; Fosco, Gregory M; Feinberg, Mark E

2018-02-01

The quality of family relationships and youth friendships are intricately linked. Previous studies have examined different mechanisms of family-peer linkage, but few have examined social anxiety. The present study examined whether parental rejection and family climate predicted changes in youth social anxiety, which in turn predicted changes in friendship quality and loneliness. Possible bidirectional associations also were examined. Data for mothers, fathers, and youth (M age at Time 1 = 11.27; 52.3% were female) from 687 two-parent households over three time points are presented. Results from autoregressive, cross-lagged analyses revealed that father rejection (not mother rejection or family climate) at Time 1 (Fall of 6th Grade) predicted increased youth social anxiety at Time 2 (Spring of 7th Grade), which in turn, predicted increased loneliness at Time 3 (Spring of 8th Grade). The indirect effect of father rejection on loneliness was statistically significant. Mother rejection, father rejection, and a poor family climate were associated with decreased friendship quality and increased loneliness over time. Finally, there was some evidence of transactional associations between father rejection and youth social anxiety as well as between social anxiety and loneliness. This study's findings underscore the important role of fathers in youth social anxiety and subsequent social adjustment.

2017-05-01

We examined the longitudinal effects of the Family Check-Up (FCU) intervention beginning in toddlerhood on children's peer preference at school-age. Specifically, a sequential mediational model was proposed in which the FCU was hypothesized to promote peer preference (i.e., higher acceptance and lower rejection by peers) in middle childhood through its positive effects on parent-child interaction and child effortful control in early childhood. Participants were 731 low-income families (49 % female). Qualities of parent-child interaction were observed during structured activities at 2 to 5 years, child effortful control was assessed using behavioral tasks at 5 years, and peer acceptance and rejection were rated by teachers at 7.5 to 10.5 years. Results indicated that the FCU indirectly predicted peer preference by sequentially improving parent-child interaction and child effortful control. The findings are discussed with respect to implications for understanding mechanisms by which early parenting-focused programs may enhance child functioning across time and context.

2017-01-01

KEY POINTS  Cross-sectional survey studies have demonstrated significant associations between parental rejection and peer rejection on the one hand and disturbed eating in youngsters, like emotional eating, on the other hand. In this study, we wanted to expand our knowledge on these relationships by investigating the daily fluctuations in these variables. Youngsters completed a 7-day diary to assess daily parental rejection, peer rejection and emotional eating. Using multilevel analyses, our results showed that daily variations in parental rejection were related to daily variations in emotional eating of the youngsters. This highlights the importance of addressing the parent-child relationship in interventions for emotional eating in youngsters. Background: This study investigated the daily relation between parental rejection and peer rejection on the one hand and emotional eating in youngsters on the other hand. Methods: Participants (N = 55) between the ages of 11 and 15 years completed a 7-day diary. A multilevel design was used to examine day-to-day within-person relationships between parental and peer rejection (measured by CHS) and emotional eating (measured by DEBQ-C) of youngsters. Results: The results showed that daily variations in parental rejection were related to daily variations in emotional eating of the youngsters. Daily peer rejection was only marginally significantly related to the emotional eating of the youngsters. Conclusions: These results indicate that especially parental rejection, and to a lesser extent peer rejection, are associated with the emotional eating of youngsters. The findings highlight the importance of addressing the parent-child relationship in interventions for emotional eating in youngsters. PMID:28553239

2017-01-01

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 Role of Reactive Aggression in the Link Between Hyperactive-Impulsive Behaviors and Peer Rejection in Adolescents.

PubMed

Evans, Spencer C; Fite, Paula J; Hendrickson, Michelle L; Rubens, Sonia L; Mages, Anna K

2015-12-01

Attention-deficit/hyperactivity disorder (ADHD) symptoms and aggressive behaviors are both associated with peer rejection, but little is known the nature of this association with respect to the two symptom dimensions of hyperactivity-impulsivity and inattention and different types of aggression. The present study examines the relations between dimensions of ADHD symptomatology, proactive and reactive aggression, and peer rejection in adolescence. Teacher-reported data were obtained for 200 high school students (grades 9-12; 48% female; predominately Latino). In structural equation modeling path analyses, the indirect effects of reactive aggression accounted for the link between hyperactivity-impulsivity and peer rejection. Within the same model, neither inattention nor proactive aggression were associated with peer rejection. These findings suggest that reactive aggression may be a key mechanism through which hyperactive-impulsive behavior is associated with peer rejection. Future research and intervention efforts should address the role of reactive aggression among youth with ADHD symptomatology.

2017-12-08

In the present study, the predictors and outcomes associated with the trajectories of peer rejection were examined in a longitudinal sample of Italian children (338 boys, 269 girls) ages 10 to 14 years. Follow-up assessments included 60% of the original sample at age 16-17. Low, medium, and high rejection trajectory groups were identified using growth mixture models. Consistent with previous studies, we found that (a) being less prosocial and more physically aggressive at age 10 was characteristic of those children with the high rejection trajectory; (b) being less attractive was related to higher peer rejection from age 10 to 14; and (c) boys with a high rejection trajectory showed high levels of delinquency and anxiety-depression and low levels of academic aspiration at age 16-17, whereas girls with a high rejection trajectory showed low levels of academic aspiration and social competence at age 16-17. Our findings indicate the detrimental consequences of peer rejection on children's development and adjustment and shed light on the mechanisms that contribute to maintaining or worsening (e.g., being attractive, prosocial, and aggressive) a child's negative status (e.g., being rejected) within his or her peer group over time.

Dishion, Thomas J.; Kim, Hanjoe; Stormshak, Elizabeth A.; O'Neill, Maya

2014-01-01

Objective Conduct a multiagent–multimethod analysis of the validity of a brief measure of deviant peer affiliations and social acceptance (PASA) in young adolescents. Peer relationships are critical to child and adolescent social and emotional development, but currently available measures are tedious and time consuming. The PASA consists of a youth, parent, and teacher report that can be collected longitudinally to study development and intervention effectiveness. Method This longitudinal study included 998 middle school students and their families. We collected the PASA and peer sociometrics data in Grade 7 and a multiagent–multimethod construct of deviant peer clustering in Grade 8. Results Confirmatory factor analyses of the multiagent–multimethod data revealed that the constructs of deviant peer affiliations and social acceptance and rejection were distinguishable as unique but correlated constructs within the PASA. Convergent, discriminant, concurrent, and predictive validity of the PASA was satisfactory, although the acceptance and rejection constructs were highly correlated and showed similar patterns of concurrent validity. Factor invariance was established for mother and for father reports. Conclusions Results suggest that the PASA is a valid and reliable measure of peer affiliation and of social acceptance among peers during the middle school years and provides a comprehensive yet brief assessment of peer affiliations and social acceptance.

Measuring the effectiveness of scientific gatekeeping.

Siler, Kyle; Lee, Kirby; Bero, Lisa

2015-01-13

Peer review is the main institution responsible for the evaluation and gestation of scientific research. Although peer review is widely seen as vital to scientific evaluation, anecdotal evidence abounds of gatekeeping mistakes in leading journals, such as rejecting seminal contributions or accepting mediocre submissions. Systematic evidence regarding the effectiveness--or lack thereof--of scientific gatekeeping is scant, largely because access to rejected manuscripts from journals is rarely available. Using a dataset of 1,008 manuscripts submitted to three elite medical journals, we show differences in citation outcomes for articles that received different appraisals from editors and peer reviewers. Among rejected articles, desk-rejected manuscripts, deemed as unworthy of peer review by editors, received fewer citations than those sent for peer review. Among both rejected and accepted articles, manuscripts with lower scores from peer reviewers received relatively fewer citations when they were eventually published. However, hindsight reveals numerous questionable gatekeeping decisions. Of the 808 eventually published articles in our dataset, our three focal journals rejected many highly cited manuscripts, including the 14 most popular; roughly the top 2 percent. Of those 14 articles, 12 were desk-rejected. This finding raises concerns regarding whether peer review is ill--suited to recognize and gestate the most impactful ideas and research. Despite this finding, results show that in our case studies, on the whole, there was value added in peer review. Editors and peer reviewers generally--but not always-made good decisions regarding the identification and promotion of quality in scientific manuscripts.

Family-Peer Linkages for Children with Intellectual Disability and Children with Learning Disabilities.

PubMed

Floyd, Frank J; Olsen, Darren L

2017-09-01

Family interactions are potential contexts for children with intellectual and learning disabilities to develop skillful social behaviors needed to relate effectively with peers. This study examined problem solving interactions within families of elementary school-age children (7-11 years) with intellectual disability (n = 37), specific learning disabilities (n =48), and without disabilities (n = 22). After accounting for group differences in children's behaviors and peer acceptance, across all groups, mothers' behaviors that encouraged egalitarian problem solving predicted more engaged and skillful problem solving by the children. However, mothers' controlling, directive behaviors predicted fewer of these behaviors by the children. Fathers' behaviors had mixed associations with the children's actions, possibly because they were reactive to children's unengaged and negative behaviors. For the children, greater involvement, more facilitative behaviors, and less negativity with their families were associated with greater acceptance from their peers, supporting family-peer linkages for children at risk for peer rejection.

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.

Fifth-grade children's daily experiences of peer victimization and negative emotions: moderating effects of sex and peer rejection.

PubMed

Morrow, Michael T; Hubbard, Julie A; Barhight, Lydia J; Thomson, Amanda K

2014-10-01

This study examined the relations of fifth-grade children's (181 boys and girls) daily experiences of peer victimization with their daily negative emotions. Children completed daily reports of peer victimization and negative emotions (sadness, anger, embarrassment, and nervousness) on up to eight school days. The daily peer victimization checklist was best represented by five factors: physical victimization, verbal victimization, social manipulation, property attacks, and social rebuff. All five types were associated with increased negative daily emotions, and several types were independently linked to increased daily negative emotions, particularly physical victimization. Girls demonstrated greater emotional reactivity in sadness to social manipulation than did boys, and higher levels of peer rejection were linked to greater emotional reactivity to multiple types of victimization. Sex and peer rejection also interacted, such that greater rejection was a stronger indicator of emotional reactivity to victimization in boys than in girls.

The present study examined sympathetic and parasympathetic indices of autonomic nervous system reactivity as moderators of the prospective association between parental management of peers via directing of youths’ friendships and peer adjustment in a sample of typically developing adolescents. Participants included 246 adolescents at Time 1 (T1) [47% boys; 66% European American (EA), 34% African American (AA)] and 226 adolescents at Time 2 (T2; 45% boys; 67% EA, 33% AA). Adolescents were approximately 16 and 17 years old at T1 and T2, respectively. To address study aims, a multi-informant, multi-method longitudinal design was utilized. Skin conductance level (SCL) and respiratory sinus arrhythmia (RSA) were measured during a baseline period and challenge task (star-tracing). Reactivity was computed as a difference score between the task and baseline period. Results from path models revealed that higher levels of mother-reported parental directing predicted decreases in adolescent-reported peer rejection and friends’ deviant behavior from T1 to T2 at relatively low levels of physiological arousal in response to challenge (i.e., low SCL reactivity, RSA augmentation). Further, exploratory analyses indicated that directing was associated with decreases in friends’ deviant behavior and peer rejection particularly among boys who exhibited lower levels of physiological arousal, but increases in friends’ deviant behavior among boys who exhibited higher levels of arousal reflected in RSA withdrawal only. Overall, findings are consistent with prior studies revealing the benefits of parental behavioral control for under-aroused youth, contributing to the growing literature on the interplay of parenting and physiological factors in the adolescent peer domain.

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.

Peer acceptance and rejection through the eyes of youth: pupillary, eyetracking and ecological data from the Chatroom Interact task

2012-01-01

We developed an ecologically valid virtual peer interaction paradigm—the Chatroom Interact Task in which 60 pre-adolescents and adolescents (ages 9–17 years) were led to believe that they were interacting with other youth in a simulated internet chatroom. Youth received rejection and acceptance feedback from virtual peers. Findings revealed increased pupil dilation, an index of increased activity in cognitive and affective processing regions of the brain, to rejection compared to acceptance trials, which was greater for older youth. Data from a cell-phone Ecological Momentary Assessment (EMA) protocol completed following the task indicated that increased pupillary reactivity to rejection trials was associated with lower feelings of social connectedness with peers in daily life. Eyetracking analyses revealed attentional biases toward acceptance feedback and away from rejection feedback. Biases toward acceptance feedback were stronger for older youth. Avoidance of rejection feedback was strongest among youth with increased pupillary reactivity to rejection, even in the seconds leading up to and following rejection feedback. These findings suggest that adolescents are sensitive to rejection feedback and seek to anticipate and avoid attending to rejection stimuli. Furthermore, the salience of social rejection and acceptance feedback appears to increase during adolescence. PMID:21775386

Bowker, Julie C; Etkin, Rebecca G

2014-01-01

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.

2017-09-01

This study investigated (1) reciprocal links among parental psychological control, peer rejection, and adolescent externalizing (aggressive and rule-breaking behaviour), and (2) the moderating effect of an adolescent genetic factor (biologically informed polygenic score for dopamine signalling). Three-year longitudinal data from 1,116 adolescents (51% boys; M age = 13.79) and their parents included psychological measures (adolescent-reported psychological control, peer-reported rejection, and parent-reported aggressive and rule-breaking behaviour). Cross-lagged analyses showed bidirectional effects between psychological control and both aggressive and rule-breaking behaviour and a unidirectional effect of peer rejection on both forms of problem behaviour over time. Multigroup structural equation modelling revealed genetic moderation only for rule-breaking behaviour: for adolescents with intermediate levels of dopamine signalling significant environmental effects were present, whereas adolescent effects of rule-breaking behaviour on psychological control were significant for adolescents with both intermediate and high profiles and effects on peer rejection only for adolescents with high dopamine profiles. Statement of contribution What is already known on this subject? Parental psychological control is related to adolescent externalizing problems. Experiencing peer rejection reinforces aggressive and rule-breaking behaviour. Single-gene studies show that dopaminergic genes influence externalizing problems directly or in interaction with the environment. What does this study add? Parental psychological control and adolescent aggressive and rule-breaking behaviour exacerbate one another longitudinally. Longitudinal associations between peer rejection and both subtypes of externalizing behaviour are unidirectional. With a polygenic approach, dopaminergic moderation is present for rule-breaking behaviour only. © 2017 The British Psychological Society.

False consensus and adolescent peer contagion: examining discrepancies between perceptions and actual reported levels of friends' deviant and health risk behaviors.

PubMed

Prinstein, Mitchell J; Wang, Shirley S

2005-06-01

Adolescents' perceptions of their friends' behavior strongly predict adolescents' own behavior, however, these perceptions often are erroneous. This study examined correlates of discrepancies between adolescents' perceptions and friends' reports of behavior. A total of 120 11th-grade adolescents provided data regarding their engagement in deviant and health risk behaviors, as well as their perceptions of the behavior of their best friend, as identified through sociometric assessment. Data from friends' own report were used to calculate discrepancy measures of adolescents' overestimations and estimation errors (absolute value of discrepancies) of friends' behavior. Adolescents also completed a measure of friendship quality, and a sociometric assessment yielding measures of peer acceptance/rejection and aggression. Findings revealed that adolescents' peer rejection and aggression were associated with greater overestimations of friends' behavior. This effect was partially mediated by adolescents' own behavior, consistent with a false consensus effect. Low levels of positive friendship quality were significantly associated with estimation errors, but not overestimations specifically.

Self-verification and depression among youth psychiatric inpatients.

PubMed

Joiner, T E; Katz, J; Lew, A S

1997-11-01

According to self-verification theory (e.g., W.B. Swann, 1983), people are motivated to preserve stable self-concepts by seeking self-confirming interpersonal responses, even if the responses are negative. In the current study of 72 youth psychiatric inpatients (36 boys; 36 girls; ages 7-17, M = 13.18; SD = 2.59), the authors provide the 1st test of self-verification theory among a youth sample. Participants completed self-report questionnaires on depression, self-esteem, anxiety, negative and positive affect, and interest in negative feedback from others. The authors made chart diagnoses available, and they collected peer rejection ratings. Consistent with hypotheses, the authors found that interest in negative feedback was associated with depression, was predictive of peer rejection (but only within relatively longer peer relationships), was more highly related to cognitive than emotional aspects of depression, and was specifically associated with depression, rather than being generally associated with emotional distress. The authors discuss implications for self-verification theory and for the phenomenology of youth depression.

2012-08-01

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.

Developmental Pathways from Childhood Aggression-Disruptiveness, Chronic Peer Rejection and Deviant Friendships to Early-Adolescent Rule Breaking

Ettekal, Idean; Ladd, Gary W.

2015-01-01

Childhood aggression-disruptiveness, chronic peer rejection, and deviant friendships were examined as predictors of early-adolescent rule breaking behaviors. Using a sample of 383 children (193 girls and 190 boys) who were followed from ages 6 to 14, peer rejection trajectories were identified and incorporated into a series of alternative models to assess how chronic peer rejection and deviant friendships mediate the association between stable childhood aggression-disruptiveness and early-adolescent rule breaking. There were multiple mediated pathways to rule breaking that included both behavioral and relational risk factors and findings were consistent for boys and girls. Results have implications for better understanding the influence of multiple social processes in the continuity of antisocial behaviors from middle childhood to early adolescence. PMID:25403544

2017-01-01

Previous research has found a strong correlation between children's academic self-concept and their behavioral problems. The present study examined whether children's peer rejection moderated the relationship between children's math and verbal self-concepts and their behavioral problems at school. We expected that children's social competence, as measured by peer rejection, moderated the negative effect of low self-concept on children's externalizing behaviors. Participants were 173 children (males = 93, M age = 10.31 years, SD = 1.43). The main findings showed that peer rejection moderated the effect of both low verbal and math self-concepts on children's externalizing behavior. The results are discussed in terms of the protective factor played by children's social competence reducing the impact of low self-concept on children's externalizing behaviors.

Independent Contributions of Early Positive Parenting and Mother-Son Coercion on Emerging Social Development.

Akcinar, Berna; Shaw, Daniel S

2018-06-01

In the current study, we explored associations between parent-child coercion and positive parenting in the toddler period in relation to children's social-behavioral development during the school-age period. The data were drawn from the Pitt Mother & Child Project, a sample of 310 low-income, ethnically diverse boys. Drawing on tenets of both attachment and social learning theory, it was hypothesized that coercive mother-son interaction would lead to reductions in positive maternal parenting in the toddler period, and that both positive parenting and mother-son coercion in the toddler period would contribute to children's conduct problems at school entry and lower social skills and peer rejection in middle childhood. The results were largely confirmed, such that mother-son coercive interaction at 18 months was related to decreases in positive parenting at 24 months. Additionally, mother-son coercive interaction and positive parenting at 24 months were linked to child conduct problems at age 5, which in turn predicted child social skills and peer rejection during middle childhood. In addition to indirect effects through child conduct problems, mother-son coercion continued to be independently related to school-age peer rejection. The findings are discussed with respect to the importance of early coercive interactions in the growth of child social-behavioral development from early to middle childhood.

Child impulsiveness-inattention, early peer experiences, and the development of early onset conduct problems.

PubMed

Snyder, James; Prichard, Joy; Schrepferman, Lynn; Patrick, M Renee; Stoolmiller, Mike

2004-12-01

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

Social Costs for Wannabes: Moderating Effects of Popularity and Gender on the Links between Popularity Goals and Negative Peer Experiences.

2018-02-05

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.

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

PubMed

King, Kevin M; McLaughlin, Katie A; Silk, Jennifer; Monahan, Kathryn C

2017-11-21

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

Peer rejection is particularly pervasive among adolescents with autism spectrum disorders (ASD). However, how adolescents with ASD differ from typically developing adolescents in their responses to peer rejection is poorly understood. The goal of the current investigation was to examine neural responses to peer exclusion among adolescents with ASD compared to typically developing adolescents. Nineteen adolescents with ASD and 17 typically developing controls underwent fMRI as they were ostensibly excluded by peers during an online game called Cyberball. Afterwards, participants reported their distress about the exclusion. Compared to typically developing adolescents, those with ASD displayed less activity in regions previously linked with the distressing aspect of peer exclusion, including the subgenual anterior cingulate and anterior insula, as well as less activity in regions previously linked with the regulation of distress responses during peer exclusion, including the ventrolateral prefrontal cortex and ventral striatum. Interestingly, however, both groups self-reported equivalent levels of distress. This suggests that adolescents with ASD may engage in differential processing of social experiences at the neural level, but be equally aware of, and concerned about, peer rejection. Overall, these findings contribute new insights about how this population may differentially experience negative social events in their daily lives.

2013-01-01

Using prospective longitudinal data, we tested 5 hypotheses: (a) that the relation between earlier developmental experiences (peer social rejection and victimization in a romantic relationship) and adult violent behavior toward peers and romantic partners is specific to relationship domain; (b) that the relation between social-information processing (SIP) biases and subsequent violence is also specific to relational domain (romantic partner vs. peer); (c) that the relation between developmental experiences and SIP biases is domain specific; (d) that domain-specific SIP mediates the impact of earlier developmental experiences on later violent behavior; and (e) that harsh parenting early in life is a domain-general predictor of SIP and later violent behavior. Harsh parenting was assessed through interviews with parents when their children were age 5 years. Classroom sociometric assessments indexing peer rejection were completed in elementary school, and self-report of victimization by romantic partners was provided at age 18 years. SIP was assessed via interview at age 22 years, and violent behavior was measured via self-and partner report at ages 23 years and 24 years. Structural equation analyses revealed specificity in the relation between developmental experiences and violence and in the prediction to and from SIP in the peer domain, but not in the romantic-relationship domain. The impact of early harsh treatment on violence toward peers was mediated by SIP biases in the peer domain. These findings provide support for domain specificity in the peer domain but for cross-domain generality in the romantic relationship domain in the development of violent behavior in early adulthood.

This paper studies performance predictions in the 7-item Cognitive Reflection Test (CRT) and whether they differ by gender. After participants completed the CRT, they predicted their own (i), the other participants’ (ii), men’s (iii), and women’s (iv) number of correct answers. In keeping with existing literature, men scored higher on the CRT than women and both men and women were too optimistic about their own performance. When we compare gender-specific predictions, we observe that men think they perform significantly better than other men and do so significantly more than women. The equality between women’s predictions about their own performance and their female peers cannot be rejected. Our findings contribute to the growing literature on the underpinnings of behavior in economics and in psychology by uncovering gender differences in confidence about one’s ability relative to same and opposite sex peers.

The socializing effect of classroom aggression on the development of aggression and social rejection: A two-wave multilevel analysis.

PubMed

Rohlf, Helena; Krahé, Barbara; Busching, Robert

2016-10-01

The current study examined the moderating effect of classroom aggression on the development of individual aggression and on the path from individual aggression to social rejection over time. The study included 1,284 elementary school children and consisted of two data waves 10months apart. At both time points, teachers assessed the children's physical and relational aggression and their social rejection status. Multi-level analyses revealed that the classroom level of relational aggression moderated the link between individual relational aggression at T1 and T2 (b=-0.18, 95% CI [-0.32, -0.05], p<.01) and the link between T1 relational aggression and T2 social rejection (b=-0.12, 95% CI [-0.23, -0.003], p<.01). Being in a classroom where relational aggression was prevalent increased relational aggression among children with a low level of relational aggression at T1. Furthermore, a high individual level of relational aggression predicted greater social rejection in classrooms with a low level of relational aggression. Children were mainly influenced by their same-gender peers. Boys as a group had a greater influence than girls on their peers of either gender in the domain of relational aggression, whereas girls as a group had a greater influence in the domain of physical aggression. The contributions of analyzing cross-level interaction to understanding the developmental patterns of aggression and social rejection in middle childhood are discussed.

Can editors save peer review from peer reviewers?

PubMed

D'Andrea, Rafael; O'Dwyer, James P

2017-01-01

Peer review is the gold standard for scientific communication, but its ability to guarantee the quality of published research remains difficult to verify. Recent modeling studies suggest that peer review is sensitive to reviewer misbehavior, and it has been claimed that referees who sabotage work they perceive as competition may severely undermine the quality of publications. Here we examine which aspects of suboptimal reviewing practices most strongly impact quality, and test different mitigating strategies that editors may employ to counter them. We find that the biggest hazard to the quality of published literature is not selfish rejection of high-quality manuscripts but indifferent acceptance of low-quality ones. Bypassing or blacklisting bad reviewers and consulting additional reviewers to settle disagreements can reduce but not eliminate the impact. The other editorial strategies we tested do not significantly improve quality, but pairing manuscripts to reviewers unlikely to selfishly reject them and allowing revision of rejected manuscripts minimize rejection of above-average manuscripts. In its current form, peer review offers few incentives for impartial reviewing efforts. Editors can help, but structural changes are more likely to have a stronger impact.

Bullied by Siblings and Peers: The Role of Rejecting/Neglecting Parenting and Friendship Quality Among Korean Children.

Kim, Jingu; Kim, Eunha

2016-07-01

The primary aim of this study was to examine the direct and indirect links of rejecting/neglecting parenting, sibling victimization, and friendship quality with peer victimization using a convenience sample of 584 Korean children in Grades 3 to 6. In addition, we tested whether these associations differed between male and female students. Structural equation modeling was performed to analyze the data. The results revealed rejecting/neglecting parenting indirectly influenced peer victimization through sibling victimization for both males and females, although such effects were stronger for females than males. Sibling victimization had a direct effect on peer victimization across both sexes, although it indirectly influenced peer victimization through poor friendship quality only for males. Therefore, bullying prevention and intervention programs must involve parents to make them aware of the important role they play in this process and to improve their parenting styles and involvement in sibling conflicts. Furthermore, while the role of friendship quality needs to be highlighted to prevent peer victimization among males, future research continues to explore other peer variables that are related to decreased peer victimization for females.

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

Peer-interactions are particularly important during adolescence and teenagers display enhanced sensitivity toward rejection by peers. Social rejection has been shown to induce alterations in pain perception in humans. However, the neurobiological consequences of adolescent social rejection have yet to be extensively characterized, and no appropriate animal model is available. Here, we propose inadequate playful interactions in adolescent rats as a novel animal model for social peer-rejection and examine potential long-term consequences into adulthood. Acute social pairing of female adolescent Wistar rats with an age-matched rat from the less playful Fischer344 strain was found to alter social play and decrease pain reactivity, indicating Fischer rats as inadequate social partners for Wistar animals. Therefore, in a second experiment, adolescent female Wistar rats were either reared with another Wistar rat (adequate social rearing; control) or with a Fischer rat (inadequate social rearing; play-deprived). Beginning on day 50, all Wistar rats were group housed with same-strain partners and tested for behavioral, neurobiological and endocrine differences in adulthood. Playful peer-interactions were decreased during adolescence in play-deprived animals, without affecting social contact behavior. Consequently, adult play-deprived rats showed decreased pain sensitivity and increased startle reactivity compared to controls, but did not differ in activity, anxiety-related behavior or social interaction. Both groups also differed in their endocrine stress-response, and expression levels of the cannabinoid CB1 receptor were increased in the thalamus, whereas FAAH levels were decreased in the amygdala. The present animal model therefore represents a novel approach to assess the long-term consequences of peer-rejection during adolescence. Copyright © 2013 Elsevier B.V. and ECNP.

Will they like me? Adolescents’ emotional responses to peer evaluation

PubMed Central

Guyer, Amanda E.; Caouette, Justin D.; Lee, Clinton C.; Ruiz, Sarah K.

2014-01-01

Relative to children and adults, adolescents are highly focused on being evaluated by peers. This increased attention to peer evaluation has implications for emotion regulation in adolescence, but little is known about the characteristics of the evaluatee and evaluator that influence emotional reactions to evaluative outcomes. The present study used a computer-based social evaluation task to examine predictors of adolescents’ emotional responses to feedback from unknown peers. Nine-to-seventeen-year-olds (N = 36) completed the “chatroom task” and indicated the degree to which each peer would be interested in interacting with them and how good they felt after receiving acceptance and rejection feedback from peers. We examined whether adolescents’ age and gender impacted their emotional responses to being accepted or rejected by peers of different age groups (i.e., early or middle adolescence) and genders. We also tested whether expectations about peers’ interest was associated with variability in adolescents’ emotional responses to the evaluative outcome. Upon being accepted by middle adolescent male peers, females in the middle relative to early years of adolescence reported greater well-being, whereas males reported similar levels of well-being regardless of their own age. Following acceptance from middle adolescent female peers, females reported greater well-being than males. Adolescents with high expectations for being liked by peers felt better after being accepted versus rejected relative to those with low expectations. For adolescents with low expectations, acceptance and rejection were associated with similar levels of well-being. Adolescents’ emotional responses to peer evaluation are influenced by specific individual characteristics and antecedent preparation for evaluation that may serve an emotion regulatory purpose.

2018-01-01

Callous unemotional (CU) behaviors are linked to aggression, behavior problems, and difficulties in peer relationships in children and adolescents. However, few studies have examined whether early childhood CU behaviors predict aggression or peer-rejection during late-childhood or potential moderation of this relationship by executive function. The current study examined whether the interaction of CU behaviors and executive function in early childhood predicted different forms of aggression in late-childhood, including proactive, reactive, and relational aggression, as well as how much children were liked by their peers. Data from cross-informant reports and multiple observational tasks were collected from a high-risk sample (N=240; female=118) at ages 3 and 10 years old. Parent reports of CU behaviors at age 3 predicted teacher reports of reactive, proactive, and relational aggression, as well as lower peer-liking at age 10. Moderation analysis showed that specifically at high levels of CU behaviors and low levels of observed executive function, children were reported by teachers as showing greater reactive and proactive aggression, and were less-liked by peers. Findings demonstrate that early childhood CU behaviors and executive function have unique main and interactive effects on both later aggression and lower peer-liking even when taking into account stability in behavior problems over time. By elucidating how CU behaviors and deficits in executive function potentiate each other during early childhood, we can better characterize the emergence of severe and persistent behavior and interpersonal difficulties across development.

2015-04-01

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).

The Importance of Friendship for Youth with Attention-Deficit/Hyperactivity Disorder

PubMed Central

Mikami, Amori Yee

2010-01-01

It is well-established that youth with attention-deficit/hyperactivity disorder (ADHD) are often peer-rejected and rated by parents, teachers, and observers to have poor social skills, when compared to typically developing peers. Significantly less research, however, has been devoted to the experiences youth with ADHD have in their close friendships. The aim of this article is to draw attention to friendship as a distinct construct from peer rejection and social skills and to summarize what is known about youth with ADHD in their friendships. The potential for stable, high-quality friendships to buffer the negative outcomes typically conferred by peer rejection in this population is discussed. This article concludes with recommendations for interventions that specifically target improving the close friendships of youth with ADHD as a treatment strategy. PMID:20490677

Making the First Cut: An Analysis of Academic Medicine Editors' Reasons for Not Sending Manuscripts Out for External Peer Review.

Meyer, Holly S; Durning, Steven J; Sklar, David P; Maggio, Lauren A

2018-03-01

Manuscripts submitted to Academic Medicine (AM) undergo an internal editor review to determine whether they will be sent for external peer review. Increasingly, manuscripts are rejected at this early stage. This study seeks to inform scholars about common reasons for internal editor review rejections, increase transparency of the process, and provide suggestions for improving submissions. A mixed-methods approach was used to retrospectively analyze editors' free-text comments. Descriptive content analysis was performed of editors' comments for 369 manuscripts submitted between December 2014 and December 2015, and rejected prior to external peer review from AM. Comments were analyzed, categorized, and counted for explicit reasons for rejection. Nine categories of rejection reasons were identified: ineffective study question and/or design (338; 92%); suboptimal data collection process (180; 49%); weak discussion and/or conclusions (139; 37%); unimportant or irrelevant topic to the journal's mission (137; 37%); weak data analysis and/or presentation of results (120; 33%); text difficult to follow, to understand (89; 24%); inadequate or incomplete introduction (67; 18%); other publishing considerations (42; 11%); and issues with scientific conduct (20; 5%). Manuscripts had, on average, three or more reasons for rejection. Findings suggest that clear identification of a research question that is addressed by a well-designed study methodology on a topic aligned with the mission of the journal would address many of the problems that lead to rejection through the internal review process. The findings also align with research on external peer review.

Reviewers’ Ratings and Bibliometric Indicators: Hand in Hand When Assessing Over Research Proposals?

PubMed Central

Cabezas-Clavijo, Álvaro; Robinson-García, Nicolás; Escabias, Manuel; Jiménez-Contreras, Evaristo

2013-01-01

Background The peer review system has been traditionally challenged due to its many limitations especially for allocating funding. Bibliometric indicators may well present themselves as a complement. Objective We analyze the relationship between peers’ ratings and bibliometric indicators for Spanish researchers in the 2007 National R&D Plan for 23 research fields. Methods and Materials We analyze peers’ ratings for 2333 applications. We also gathered principal investigators’ research output and impact and studied the differences between accepted and rejected applications. We used the Web of Science database and focused on the 2002-2006 period. First, we analyzed the distribution of granted and rejected proposals considering a given set of bibliometric indicators to test if there are significant differences. Then, we applied a multiple logistic regression analysis to determine if bibliometric indicators can explain by themselves the concession of grant proposals. Results 63.4% of the applications were funded. Bibliometric indicators for accepted proposals showed a better previous performance than for those rejected; however the correlation between peer review and bibliometric indicators is very heterogeneous among most areas. The logistic regression analysis showed that the main bibliometric indicators that explain the granting of research proposals in most cases are the output (number of published articles) and the number of papers published in journals that belong to the first quartile ranking of the Journal Citations Report. Discussion Bibliometric indicators predict the concession of grant proposals at least as well as peer ratings. Social Sciences and Education are the only areas where no relation was found, although this may be due to the limitations of the Web of Science’s coverage. These findings encourage the use of bibliometric indicators as a complement to peer review in most of the analyzed areas. PMID:23840840

Peer and Teacher Effects on the Early Onset of Sexual Intercourse

2007-01-01

Objectives. We examined the links between peer rejection and verbal abuse by a teacher during childhood with the early onset of sexual intercourse and the mediating role of delinquent behavior and low self-esteem in this context. Methods. We assessed 312 students (159 girls) in northwestern Quebec annually from kindergarten through seventh grade. Peer identifications were used to assess peer rejection and verbal abuse by teachers from kindergarten through fourth grade. In seventh grade, self-reports were used to assess delinquent behavior, self-esteem, and having sexual intercourse. Multiple sources were used to assess control variables. Results. Multiple imputation-based linear and logistic regressions showed that peer rejection was indirectly associated with a higher risk of early intercourse by its link with lower self-esteem, but only for girls. Verbal abuse by teachers during childhood was directly associated with a higher risk of early sexual intercourse and indirectly by its link with delinquent behavior. Conclusions. The results underline the importance of both peers and teachers in healthy sexual development among youths, especially for girls, and emphasize the need for targeted health and sexual education programs.

Forms of aggression, peer relationships, and relational victimization among Chinese adolescent girls and boys: roles of prosocial behavior

2015-01-01

Through a sample of 686 Chinese adolescents (mean age = 13.73 years; 50% girls), we examined the compensatory and moderating effects of prosocial behavior on the direct and indirect associations between forms of aggression and relational victimization mediated by peer relationships among adolescent girls and boys. The results indicated that only adolescent girls’ relationally aggressive behaviors could be directly linked with their experiences of relational victimization, and both relationally and overtly aggressive adolescent boys and girls might be more often rejected by their peers, which, in turn, could make them targets of relational aggression. Next, we found that prosocial behavior indirectly counteracts the effects of aggression on relational victimization through reducing adolescents’ peer rejection and promoting adolescents’ peer attachment. In addition, relationally aggressive girls with high levels of prosocial behavior might be less rejected by peers; however, they might also have lower levels of peer attachment and be more likely to experience relational victimization. Last, adolescent boys scored higher on risks, but lower on the protective factors of relational victimization than girls, which, to some degree, might explain the gender difference in relational victimization. Finally, we discussed the theoretical and practical implications of these findings. PMID:26347704

Understanding adolescent peer sexual harassment and abuse: using the theory of planned behavior.

PubMed

Li, Man Yu; Frieze, Irene; Tang, Catherine So-kum

2010-06-01

This study examines intentions to take protective action against peer sexual harassment and abuse (PSHA). The theory of planned behavior (TPB) proposes that attitudes about protective action, perceptions of what others would think about doing this (subjective norms), and behavioral control would be important predictors. A total of 1,531 Chinese secondary school students (769 boys and 762 girls) from Hong Kong were surveyed to test this model. Results showed that the TPB model was predictive for girls, but only subjective norms and behavioral control significantly predicted boys' intentions to protect themselves. Results supported the influence of subjective norms and perceived behavioral control on youths' intentions to reject PSHA. These factors may be useful in guiding the development of an educational program for prevention of PSHA.

Anticipation of peer evaluation in anxious adolescents: divergence in neural activation and maturation

Jarcho, Johanna M.; Dahl, Ronald E.; Pine, Daniel S.; Ernst, Monique; Nelson, Eric E.

2015-01-01

Adolescence is the time of peak onset for many anxiety disorders, particularly Social Anxiety Disorder. Research using simulated social interactions consistently finds differential activation in several brain regions in anxious (vs non-anxious) youth, including amygdala, striatum and medial prefrontal cortex. However, few studies examined the anticipation of peer interactions, a key component in the etiology and maintenance of anxiety disorders. Youth completed the Chatroom Task while undergoing functional magnetic resonance imaging. Patterns of neural activation were assessed in anxious and non-anxious youth as they were cued to anticipate social feedback from peers. Anxious participants evidenced greater amygdala activation and rostral anterior cingulate (rACC)↔amygdala coupling than non-anxious participants during anticipation of feedback from peers they had previously rejected; anxious participants also evidenced less nucleus accumbens activation during anticipation of feedback from selected peers. Finally, anxiety interacted with age in rACC: in anxious participants, age was positively associated with activation to anticipated feedback from rejected peers and negatively for selected peers, whereas the opposite pattern emerged for non-anxious youth. Overall, anxious youth showed greater reactivity in anticipation of feedback from rejected peers and thus may ascribe greater salience to these potential interactions and increase the likelihood of avoidance behavior.

2012-01-01

The first objective was to determine the prevalence of psychological maladjustment (emotional and behavioural problems), low academic competencies and teasing/social rejection among obese Icelandic children enrolling in a family-based behavioural treatment. A second objective was to explore the degree to which teasing/social rejection specifically contributes to children's psychological adjustment and academic competencies when controlling for other variables, including demographics, children's physical activity, parental depression and life-stress. Participants were 84 obese children (mean body mass index-standard deviation score=3.11, age range=7.52-13.61 years). Height and weight, demographics and measures of children's psychological adjustment, academic competencies, teasing/social rejection and physical activity were collected from children, parents and teachers. Parental depression and life-stress was self-reported. Over half the children exceeded cutoffs indicating concern on at least one measure of behavioural or emotional difficulties. Children endorsed significant levels of teasing/social rejection, with almost half acknowledging they were not popular with same-gender peers. Parent reports of peer problems were even higher, with over 90% of both boys and girls being rated by their parents as having significant peer difficulties. However, rates of low academic competencies as reported by teachers were not different from those of the general population. In regression analyses controlling for other variables, self-reported teasing/social rejection emerged as a significant contributor to explaining both child psychological adjustment and academic competencies. The results indicate that among obese children enrolled in family-based treatment, self-reported teasing/social rejection is quite high and it is associated with poorer psychological adjustment as well as lower academic competencies. Parent reports corroborate the presence of substantial peer difficulties, supporting the need to address peer relations with overweight children both in clinical practice and in public health interventions.

Children's feedback preferences in response to an experimentally manipulated peer evaluation outcome: the role of depressive symptoms.

PubMed

Reijntjes, Albert; Dekovic, Maja; Vermande, Marjolijn; Telch, Michael J

2007-06-01

The present study examined the linkage between pre-adolescent children's depressive symptoms and their preferences for receiving positive vs. negative feedback subsequent to being faced with an experimentally manipulated peer evaluation outcome in real time. Participants (n = 142) ages 10 to 13, played a computer contest based on the television show Survivor and were randomized to either a peer rejection (i.e., receiving the lowest total 'likeability' score from a group of peer-judges), a peer success (i.e., receiving the highest score), or a control peer evaluation condition. Children's self-reported feedback preferences were then assessed. Results revealed that participants assigned to the negative evaluation outcome, relative to either the success or the control outcome, showed a significantly higher subsequent preference for negatively tuned feedback. Contrary to previous work and predictions derived from self-verification theory, children higher in depressive symptoms were only more likely to prefer negative feedback in response to the negative peer evaluation outcome. These effects for depression were not accounted for by either state mood at baseline or mood change in response to the feedback manipulation.

Sexual experience among emotionally and behaviorally disordered students in therapeutic day schools: an ecological examination of adolescent risk.

Donenberg, Geri R; Emerson, Erin; Brown, Larry K; Houck, Christopher; Mackesy-Amiti, Mary Ellen

2012-09-01

This study examined gender differences in family, peer, partner, and mental health characteristics related to sexual experience among emotionally and behaviorally disordered students in therapeutic day schools, a population at elevated risk for negative sexual health outcomes. A total of 417 13- to 20-year-old adolescents reported on their family functioning, peer and partner relationship characteristics, mental health problems, and self-reported sexual behavior. For boys and girls, peer influence and conduct problems predicted sexual experience, and family dysfunction was related to negative peer influence. Greater rejection sensitivity was related to less sexual experience for boys and girls. The final path model revealed indirect effects of family dysfunction on boys' but not girls' sexual experiences. Findings underscore the utility of an ecological approach to understand social and personal mechanisms that increase risk and mitigate negative outcomes among emotionally and behaviorally disordered boys and girls in therapeutic day schools.

Comparing acceptance and rejection in the classroom interaction of students who stutter and their peers: A social network analysis.

Adriaensens, Stefanie; Van Waes, Sara; Struyf, Elke

2017-06-01

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.

Self-concept and psychopathology in deaf adolescents: preliminary support for moderating effects of deafness-related characteristics and peer problems.

van Gent, Tiejo; Goedhart, Arnold W; Treffers, Philip D A

2011-06-01

High rates of psychopathology were found amongst deaf adolescents, but little is known about the psychosocial risk factors. This study investigated whether (1) less severe deafness and/or acquired or otherwise complicated deafness, and (2) having mainly contacts with hearing people, each represent chronic stressful conditions that moderate the associations between self-esteem and emotional problems. In addition, the moderating effect of observed peer rejection on the association between social acceptance and behavioural problems was explored. Deaf adolescents of normal intelligence (N = 68) completed the Self Perception Profile for Adolescents. Psychopathology was assessed using a semi-structured interview with adolescents and reports by parents, teachers and expert ratings. Data on moderator variables were collected from school records, parental and teachers' reports. Emotional mental health problems were negatively associated with self-esteem and positively with peer rejection. The association between self-esteem and emotional problems was moderated by the deafness variable less severe deafness or acquired or otherwise complicated deafness. Behavioural mental health problems were positively associated with social acceptance and peer rejection but negatively with the amount of involvement with hearing people. Peer rejection moderated the association between social acceptance and behavioural problems. The findings emphasise the importance of considering self-concept dimensions, peer problems and deafness- and context-related characteristics when assessing and treating deaf adolescents. © 2011 The Authors.

Erhardt, Drew; Hinshaw, Stephen P

1994-08-01

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

Parents, teachers and peer relations as predictors of risk behaviors and mental well-being among immigrant and Israeli born adolescents.

This study examines the roles of parents (monitoring, involvement and support at school), teachers (support) and peers (excess time spent with friends, peer rejection at school) in predicting risk behaviors (smoking and drinking) and mental well-being among 3499 Israeli-born and 434 immigrant adolescents ages 11, 13 and 15, in the 2006 WHO Health Behavior in School-Aged Children cross-national survey. Structural Equation Modeling (SEM) showed that for native Israeli youth, in line with previous developmental literature, all three relationships - parents, teachers and peers - have a significant impact on both mental well-being and risk behaviors. However, for immigrant adolescents, it was the school environment (parental support at school, teacher support and peer relationships) that proved to be the significant predictor of risk behaviors and mental health outcomes. These findings suggest that the school is an important social support in the health and mental well-being of immigrant schoolchildren. (c) 2010 Elsevier Ltd. All rights reserved.

Anticipation of peer evaluation in anxious adolescents: divergence in neural activation and maturation.

PubMed

Spielberg, Jeffrey M; Jarcho, Johanna M; Dahl, Ronald E; Pine, Daniel S; Ernst, Monique; Nelson, Eric E

2015-08-01

Adolescence is the time of peak onset for many anxiety disorders, particularly Social Anxiety Disorder. Research using simulated social interactions consistently finds differential activation in several brain regions in anxious (vs non-anxious) youth, including amygdala, striatum and medial prefrontal cortex. However, few studies examined the anticipation of peer interactions, a key component in the etiology and maintenance of anxiety disorders. Youth completed the Chatroom Task while undergoing functional magnetic resonance imaging. Patterns of neural activation were assessed in anxious and non-anxious youth as they were cued to anticipate social feedback from peers. Anxious participants evidenced greater amygdala activation and rostral anterior cingulate (rACC)↔amygdala coupling than non-anxious participants during anticipation of feedback from peers they had previously rejected; anxious participants also evidenced less nucleus accumbens activation during anticipation of feedback from selected peers. Finally, anxiety interacted with age in rACC: in anxious participants, age was positively associated with activation to anticipated feedback from rejected peers and negatively for selected peers, whereas the opposite pattern emerged for non-anxious youth. Overall, anxious youth showed greater reactivity in anticipation of feedback from rejected peers and thus may ascribe greater salience to these potential interactions and increase the likelihood of avoidance behavior. © The Author (2014).

Associations Among Pubertal Development, Empathic Ability, and Neural Responses While Witnessing Peer Rejection in Adolescence

PubMed Central

Masten, Carrie L.; Eisenberger, Naomi I.; Pfeifer, Jennifer H.; Colich, Natalie L.; Dapretto, Mirella

2012-01-01

Links among concurrent and longitudinal changes in pubertal development and empathic ability from age 10 to 13 and neural responses while witnessing peer rejection at age 13 were examined in 16 participants. More advanced pubertal development at age 13, and greater longitudinal increases in pubertal development, related to increased activity in regions underlying cognitive aspects of empathy. Likewise, at age 13 greater perspective taking related to activity in cognitive empathy-related regions; however, affective components of empathy (empathic concern and personal distress) were additionally associated with activity in affective pain-related regions. Longitudinal increases in empathic ability related to cognitive and affective empathy-related circuitry. Findings provide preliminary evidence that physical and cognitive-emotional development relate to adolescents’ neural responses when witnessing peer rejection. PMID:23379360

Sluggish cognitive tempo and attention-deficit/hyperactivity disorder (ADHD) inattention in the home and school contexts: Parent and teacher invariance and cross-setting validity.

2017-02-01

This study examined whether sluggish cognitive tempo (SCT) and attention-deficit/hyperactivity disorder (ADHD) inattention (IN) symptoms demonstrated cross-setting invariance and unique associations with symptom and impairment dimensions across settings (i.e., home SCT and ADHD-IN uniquely predicting school symptom and impairment dimensions, and vice versa). Mothers, fathers, primary teachers, and secondary teachers rated SCT, ADHD-IN, ADHD-hyperactivity/impulsivity (HI), oppositional defiant disorder (ODD), anxiety, depression, academic impairment, social impairment, and peer rejection dimensions for 585 Spanish 3rd-grade children (53% boys). Within-setting (i.e., mothers, fathers; primary, secondary teachers) and cross-settings (i.e., home, school) invariance was found for both SCT and ADHD-IN. From home to school, higher levels of home SCT predicted lower levels of school ADHD-HI and higher levels of school academic impairment after controlling for home ADHD-IN, whereas higher levels of home ADHD-IN predicted higher levels of school ADHD-HI, ODD, anxiety, depression, academic impairment, and peer rejection after controlling for home SCT. From school to home, higher levels of school SCT predicted lower levels of home ADHD-HI and ODD and higher levels of home anxiety, depression, academic impairment, and social impairment after controlling for school ADHD-IN, whereas higher levels of school ADHD-IN predicted higher levels of home ADHD-HI, ODD, and academic impairment after controlling for school SCT. Although SCT at home and school was able to uniquely predict symptom and impairment dimensions in the other setting, SCT at school was a better predictor than ADHD-IN at school of psychopathology and impairment at home. Findings provide additional support for SCT's validity relative to ADHD-IN. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

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

Pathways From Depressive Symptoms to Low Social Status

PubMed Central

Agoston, Anna M.; Rudolph, Karen D.

2012-01-01

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

All the opinions in this article are those of the authors and should not be construed to reflect, in any way, those of the Department of Veterans Affairs. Background Our study purpose was to assess the predictive validity of reviewer quality ratings and editorial decisions in a general medicine journal. Methods Submissions to the Journal of General Internal Medicine (JGIM) between July 2004 and June 2005 were included. We abstracted JGIM peer review quality ratings, verified the publication status of all articles and calculated an impact factor for published articles (Rw) by dividing the 3-year citation rate by the average for this group of papers; an Rw>1 indicates a greater than average impact. Results Of 507 submissions, 128 (25%) were published in JGIM, 331 rejected (128 with review) and 48 were either not resubmitted after revision was requested or were withdrawn by the author. Of 331 rejections, 243 were published elsewhere. Articles published in JGIM had a higher citation rate than those published elsewhere (Rw: 1.6 vs. 1.1, p = 0.002). Reviewer quality ratings of article quality had good internal consistency and reviewer recommendations markedly influenced publication decisions. There was no quality rating cutpoint that accurately distinguished high from low impact articles. There was a stepwise increase in Rw for articles rejected without review, rejected after review or accepted by JGIM (Rw 0.60 vs. 0.87 vs. 1.56, p<0.0005). However, there was low agreement between reviewers for quality ratings and publication recommendations. The editorial publication decision accurately discriminated high and low impact articles in 68% of submissions. We found evidence of better accuracy with a greater number of reviewers. Conclusions The peer review process largely succeeds in selecting high impact articles and dispatching lower impact ones, but the process is far from perfect. While the inter-rater reliability between individual reviewers is low, the accuracy of sorting is improved with a greater number of reviewers. PMID:21799867

Children’s social self-concept and internalizing problems: the influence of peers and teachers.

2014-01-01

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.

Deficiencies in medical education research quality are widely acknowledged. Content, internal structure, and criterion validity evidence support the use of the Medical Education Research Study Quality Instrument (MERSQI) to measure education research quality, but predictive validity evidence has not been explored. To describe the quality of manuscripts submitted to the 2008 Journal of General Internal Medicine (JGIM) medical education issue and determine whether MERSQI scores predict editorial decisions. Cross-sectional study of original, quantitative research studies submitted for publication. Study quality measured by MERSQI scores (possible range 5-18). Of 131 submitted manuscripts, 100 met inclusion criteria. The mean (SD) total MERSQI score was 9.6 (2.6), range 5-15.5. Most studies used single-group cross-sectional (54%) or pre-post designs (32%), were conducted at one institution (78%), and reported satisfaction or opinion outcomes (56%). Few (36%) reported validity evidence for evaluation instruments. A one-point increase in MERSQI score was associated with editorial decisions to send manuscripts for peer review versus reject without review (OR 1.31, 95%CI 1.07-1.61, p = 0.009) and to invite revisions after review versus reject after review (OR 1.29, 95%CI 1.05-1.58, p = 0.02). MERSQI scores predicted final acceptance versus rejection (OR 1.32; 95% CI 1.10-1.58, p = 0.003). The mean total MERSQI score of accepted manuscripts was significantly higher than rejected manuscripts (10.7 [2.5] versus 9.0 [2.4], p = 0.003). MERSQI scores predicted editorial decisions and identified areas of methodological strengths and weaknesses in submitted manuscripts. Researchers, reviewers, and editors might use this instrument as a measure of methodological quality.

We report findings from a pilot intervention that trained parents to be "friendship coaches" for their children with Attention-Deficit/Hyperactivity Disorder (ADHD). Parents of 62 children with ADHD (ages 6-10; 68% male) were randomly assigned to receive the parental friendship coaching (PFC) intervention, or to be in a no-treatment control group. Families of 62 children without ADHD were included as normative comparisons. PFC was administered in eight, 90-minute sessions to parents; there was no child treatment component. Parents were taught to arrange a social context in which their children were optimally likely to develop good peer relationships. Receipt of PFC predicted improvements in children's social skills and friendship quality on playdates as reported by parents, and peer acceptance and rejection as reported by teachers unaware of treatment status. PFC also predicted increases in observed parental facilitation and corrective feedback, and reductions in criticism during the child's peer interaction, which mediated the improvements in children's peer relationships. However, no effects for PFC were found on the number of playdates hosted or on teacher report of child social skills. Findings lend initial support to a treatment model that targets parental behaviors to address children's peer problems.

Abstract This invited editorial addresses the rescue of the article by Skrzypek et al. “Interplay between heme oxygenase-1 and miR-378 affects non-small cell lung carcinoma growth, vascularization, and metastasis.” The work was rejected by the standard peer review system and subsequently rescued by the Rebound Peer Review (RPR) mechanism offered by Antioxidants and Redox Signaling (Antioxid Redox Signal 16: 293–296, 2012). The reviewers who openly rescued the article were James F. George, Justin C. Mason, Mahin D. Maines, and Yasufumi Sato. The initial article was a de novo resubmission of a previously rejected article, which was then reviewed by six reviewers. The reviewers raised substantial scientific concerns, including questions pertaining to the specificity of the findings, quality of the presentation, and other technical concerns; the editor returned a decision of reject. The authors voluntarily chose to exercise the option to rescue the article utilizing the RPR system, where the authors found qualified reviewers who were willing to advocate for acceptance with scientific reasoning. The open reviewers felt that the scientific and technical concerns raised by the reviewers were outweighed by the strengths and novelty of the findings to justify acceptance. The RPR, in this case, was a “success” in that it rescued a rejected article. Despite this assessment, we question the necessity of open peer review as a means to overturn a peer review decision, with concerns for the larger-than-usual peer review process, and the voluntary relinquishing of editorial privilege and disclosure of reviewer identity.

A Longitudinal Study of Rejecting and Autonomy-Restrictive Parenting, Rejection Sensitivity, and Socioemotional Symptoms in Early Adolescents.

PubMed

Rowe, Susan L; Gembeck, Melanie J Zimmer; Rudolph, Julia; Nesdale, Drew

2015-08-01

Rejection sensitivity (RS) has been defined as the tendency to readily perceive and overreact to interpersonal rejection. The primary aim of this study was to test key propositions of RS theory, namely that rejecting experiences in relationships with parents are antecedents of early adolescents' future RS and symptomatology. We also expanded this to consider autonomy-restrictive parenting, given the importance of autonomy in early adolescence. Participants were 601 early adolescents (age 9 to 13 years old, 51% boys) from three schools in Australia. Students completed questionnaires at school about parent and peer relationships, RS, loneliness, social anxiety, and depression at two times with a 14-month lag between assessments. Parents also reported on adolescents' difficulties at Time 1 (T1). It was anticipated that more experience of parental rejection, coercion, and psychological control would be associated with adolescents' escalating RS and symptoms over time, even after accounting for peer victimisation, and that RS would mediate associations between parenting and symptoms. Structural equation modelling supported these hypotheses. Parent coercion was associated with adolescents' increasing symptoms of social anxiety and RS over time, and parent psychological control was associated with increasing depressive symptoms over time. Indirect effects via RS were also found, with parent rejection and psychological control linked to higher T1 RS, which was then associated with increasing loneliness and RS. Lastly, in a separate model, peer victimisation and RS, but not parenting practices, were positively associated with concurrent parent reports of adolescents' difficulties.

Differential risk for late adolescent conduct problems and mood dysregulation among children with early externalizing behavior problems.

PubMed

Okado, Yuko; Bierman, Karen L

2015-05-01

To investigate the differential emergence of antisocial behaviors and mood dysregulation among children with externalizing problems, the present study prospectively followed 317 high-risk children with early externalizing problems from school entry (ages 5-7) to late adolescence (ages 17-19). Latent class analysis conducted on their conduct and mood symptoms in late adolescence revealed three distinct patterns of symptoms, characterized by: 1) criminal offenses, conduct disorder symptoms, and elevated anger ("conduct problems"), 2) elevated anger, dysphoric mood, and suicidal ideation ("mood dysregulation"), and 3) low levels of severe conduct and mood symptoms. A diathesis-stress model predicting the first two outcomes was tested. Elevated overt aggression at school entry uniquely predicted conduct problems in late adolescence, whereas elevated emotion dysregulation at school entry uniquely predicted mood dysregulation in late adolescence. Experiences of low parental warmth and peer rejection in middle childhood moderated the link between early emotion dysregulation and later mood dysregulation but did not moderate the link between early overt aggression and later conduct problems. Thus, among children with early externalizing behavior problems, increased risk for later antisocial behavior or mood dysfunction may be identifiable in early childhood based on levels of overt aggression and emotion dysregulation. For children with early emotion dysregulation, however, increased risk for mood dysregulation characterized by anger, dysphoric mood, and suicidality--possibly indicative of disruptive mood dysregulation disorder--emerges only in the presence of low parental warmth and/or peer rejection during middle childhood.

Will they like me? Neural and behavioral responses to social-evaluative peer feedback in socially and non-socially anxious females.

PubMed

van der Molen, Melle J W; Harrewijn, Anita; Westenberg, P Michiel

2018-05-01

The current study examined neural and behavioral responses to social-evaluative feedback processing in social anxiety. Twenty-two non-socially and 17 socially anxious females (mean age = 19.57 years) participated in a Social Judgment Paradigm in which they received peer acceptance/rejection feedback that was either congruent or incongruent with their prior predictions. Results indicated that socially anxious participants believed they would receive less social acceptance feedback than non-socially anxious participants. EEG results demonstrated that unexpected social rejection feedback elicited a significant increase in theta (4-8 Hz) power relative to other feedback conditions. This theta response was only observed in non-socially anxious individuals. Together, results corroborate cognitive-behavioral studies demonstrating a negative expectancy bias in socially anxiety with respect to social evaluation. Furthermore, the present findings highlight a functional role for theta oscillatory dynamics in processing cues that convey social-evaluative threat, and this social threat-monitoring mechanism seems less sensitive in socially anxious females.

Family support and rejection are associated with health outcomes among sexual minority women (SMW). We examined a social ecological development model among young adult SMW, testing whether identity risk factors or outness to family interacted with family rejection to predict community connectedness and collective self-esteem. Lesbian and bisexual women (N = 843; 57% bisexual) between the ages of 18-25 (M = 21.4; SD = 2.1) completed baseline and 12-month online surveys. The sample identified as White (54.2%), multiple racial backgrounds (16.6%), African American (9.6%) and Asian/Asian American (3.1%); 10.2% endorsed a Hispanic/Latina ethnicity. Rejection ranged from 18 to 41% across family relationships. Longitudinal regression indicated that when outness to family increased, SMW in highly rejecting families demonstrated resilience by finding connections and esteem in sexual minority communities to a greater extent than did non-rejected peers. But, when stigma concerns, concealment motivation, and other identity risk factors increased over the year, high family rejection did not impact community connectedness and SMW reported lower collective self-esteem. Racial minority SMW reported lower community connectedness, but not lower collective self-esteem. Families likely buffer or exacerbate societal risks for ill health. Findings highlight the protective role of LGBTQ communities and normative resilience among SMW and their families.

Little is known about normative variation in stress response over the adolescent transition. This study examined neuroendocrine and cardiovascular responses to performance and peer rejection stressors over the adolescent transition in a normative sample. Participants were 82 healthy children (ages 7-12 years, n=39, 22 females) and adolescents (ages 13-17, n=43, 20 females) recruited through community postings. Following a habituation session, participants completed a performance (public speaking, mental arithmetic, mirror tracing) or peer rejection (exclusion challenges) stress session. Salivary cortisol, alpha amylase (sAA), systolic and diastolic blood pressure (SBP, DBP), and heart rate (HR) were measured throughout. Adolescents showed significantly greater cortisol, sAA, SBP and DBP stress response relative to children. Developmental differences were most pronounced in the performance stress session for cortisol and DBP, and in the peer rejection session for sAA and SBP. Heightened physiological stress responses in typical adolescents may facilitate adaptation to new challenges of adolescence and adulthood. In high-risk adolescents, this normative shift may tip the balance toward stress response dysregulation associated with depression and other psychopathology. Specificity of physiological response by stressor type highlights the importance of a multi-system approach to the psychobiology of stress and may also have implications for understanding trajectories to psychopathology.

The present study examined the linkage between pre-adolescent children’s depressive symptoms and their preferences for receiving positive vs. negative feedback subsequent to being faced with an experimentally manipulated peer evaluation outcome in real time. Participants (n = 142) ages 10 to 13, played a computer contest based on the television show Survivor and were randomized to either a peer rejection (i.e., receiving the lowest total ‘likeability’ score from a group of peer-judges), a peer success (i.e., receiving the highest score), or a control peer evaluation condition. Children’s self-reported feedback preferences were then assessed. Results revealed that participants assigned to the negative evaluation outcome, relative to either the success or the control outcome, showed a significantly higher subsequent preference for negatively tuned feedback. Contrary to previous work and predictions derived from self-verification theory, children higher in depressive symptoms were only more likely to prefer negative feedback in response to the negative peer evaluation outcome. These effects for depression were not accounted for by either state mood at baseline or mood change in response to the feedback manipulation. PMID:17279340

This study examined the social situations that are problematic for peer-rejected students in the first year of elementary school. For this purpose, exploratory and confirmatory factor analyses were conducted on the Taxonomy of Problematic Social Situations for Children (TOPS, Dodge et al., 1985) in 169 rejected pupils, identified from a sample of 1457 first-grade students (ages 5-7) enrolled in 62 classrooms of elementary school. For each rejected student, another student of average sociometric status of the same gender was selected at random from the same classroom ( n average = 169). The model for the rejected students showed a good fit, and was also invariant in the group of average students. Four types of situations were identified in which rejected students have significantly more difficulties than average students. They are, in descending order: (a) respect for authority and rules, (b) being disadvantaged, (c) prosocial and empathic behavior, and (d) response to own success. Rejected boys have more problems in situations of prosociability and empathy than girls. The implications concerning the design of specific programs to prevent and reduce early childhood rejection in the classroom are discussed.

2006-11-01

This study examined children's spontaneous use of behavioral emotion regulation (ER) strategies and their effects on subsequent mood change in response to an in vivo peer rejection manipulation. Participants (N = 186), ranging between 10 and 13 years of age, played a computer game based on the television show Survivor and were randomized to either peer rejection (being voted out of the game) or nonrejection control. In response to rejection, more than one third of the participants (38%) displayed a marked worsening (i.e., reliable change) in state mood. After receiving feedback, time spent on several behavioral ER strategies during a 5-minute postfeedback period was assessed. At the end of the postfeedback period, children's cognitive activity was also assessed. More time spent on behavioral distraction was positively linked to subsequent increases in positive affect, whereas the reverse pattern was found for disengagement/passive behavior. Moreover, higher endorsement ratings for the strategy of "cognitive analysis" were associated with stronger increases in negative affect. Copyright 2006 APA, all rights reserved.

Why don't you like me? Midfrontal theta power in response to unexpected peer rejection feedback.

PubMed

van der Molen, M J W; Dekkers, L M S; Westenberg, P M; van der Veen, F M; van der Molen, M W

2017-02-01

Social connectedness theory posits that the brain processes social rejection as a threat to survival. Recent electrophysiological evidence suggests that midfrontal theta (4-8Hz) oscillations in the EEG provide a window on the processing of social rejection. Here we examined midfrontal theta dynamics (power and inter-trial phase synchrony) during the processing of social evaluative feedback. We employed the Social Judgment paradigm in which 56 undergraduate women (mean age=19.67 years) were asked to communicate their expectancies about being liked vs. disliked by unknown peers. Expectancies were followed by feedback indicating social acceptance vs. rejection. Results revealed a significant increase in EEG theta power to unexpected social rejection feedback. This EEG theta response could be source-localized to brain regions typically reported during activation of the saliency network (i.e., dorsal anterior cingulate cortex, insula, inferior frontal gyrus, frontal pole, and the supplementary motor area). Theta phase dynamics mimicked the behavior of the time-domain averaged feedback-related negativity (FRN) by showing stronger phase synchrony for feedback that was unexpected vs. expected. Theta phase, however, differed from the FRN by also displaying stronger phase synchrony in response to rejection vs. acceptance feedback. Together, this study highlights distinct roles for midfrontal theta power and phase synchrony in response to social evaluative feedback. Our findings contribute to the literature by showing that midfrontal theta oscillatory power is sensitive to social rejection but only when peer rejection is unexpected, and this theta response is governed by a widely distributed neural network implicated in saliency detection and conflict monitoring.

Working memory and social functioning in children.

McQuade, Julia D; Murray-Close, Dianna; Shoulberg, Erin K; Hoza, Betsy

2013-07-01

This study extends previous research and examines whether working memory (WM) is associated with multiple measures of concurrent social functioning (peer rejection, overall social competence, relational aggression, physical aggression, and conflict resolutions skills) in typically developing fourth- and fifth-grade children (N=116). Poor central executive WM was associated with both broad social impairments (peer rejection and poor overall social competence) and specific social impairments (physical aggression, relational aggression, and impaired conflict resolution skills); poor verbal storage was associated only with greater peer rejection, and spatial storage was not associated with any measures of social impairment. Analyses also examined whether specific impairments in aggressive behavior and conflict resolution skills mediated the association between central executive and broad measures of social functioning. Greater physical aggression and impaired conflict resolution skills were both significant mediators; relational aggression was not. Implications for theory and future research are discussed.

Utilized a pattern-based approach to discover the different constellations of perceived social transactions separately for family and peer systems and explored the risk and protective functions of these microsystem profiles for both depression and antisocial behavior among a sample of ethnically and racially diverse urban adolescents living in poverty. Measures of perceived social support, involvement and hassles with family and peers, as well as perceived social acceptance and peers' values were entered into two sets of iterative cluster analyses to identify distinct profiles of family and peer transactions. From each of the perceived family and peer transactional analyses, six replicated profiles emerged. Several of the profiles were consistent with expectations from prior literature such as Enmeshing families and Rejecting peer networks, while others were novel and intriguing such as Entangling peers. Family profiles were consistent in their risk and protective associations for both depression and antisocial behavior, while the peer profiles varied in their effects for each developmental outcome. For example, the Rejecting peer profile placed adolescents at increased risk for depression but protected them from antisocial behavior. Implications for future research and preventive intervention are discussed.

2017-02-01

To evaluate whether quality of peer review and reviewer recommendation differ based on reviewer subspecialty in obstetrics and gynecology and to determine the role of experience on reviewer recommendation. We performed a retrospective cohort study of reviews submitted to Obstetrics & Gynecology between January 2010 and December 2014. Subspecialties were determined based on classification terms selected by each reviewer and included all major obstetrics and gynecology subspecialties, general obstetrics and gynecology, and nonobstetrics and gynecology categories. Review quality (graded on a 5-point Likert scale by the journal's editors) and reviewer recommendation of "reject" were compared across subspecialties using χ, analysis of variance, and multivariate logistic regression. There were 20,027 reviews from 1,889 individual reviewers. Reviewers with family planning subspecialty provided higher-quality peer reviews compared with reviewers with gynecology only, reproductive endocrinology and infertility, gynecologic oncology, and general obstetrics and gynecology specialties (3.61±0.75 compared with 3.44±0.78, 3.42±0.72, 3.35±0.75, and 3.32±0.81, respectively, P<.05). Reviewers with gynecology-only subspecialty recommended rejection more often compared with reviewers with a nonobstetrics and gynecology subspecialty (57.7% compared with 38.7%, P<.05). Editorial Board members recommended rejection more often than new reviewers (68.0% compared with 41.5%, P<.05). Increased adjusted odds of manuscript rejection recommendation were associated with reproductive endocrinology, female pelvic medicine and reconstructive surgery, and gynecology-only reviewer subspecialty (adjusted odds ratio [OR] 1.23 [1.07-1.41], 1.21 [1.05-1.39], and 1.11 [1.02-1.20]). Manuscript rejection recommendation rate was also increased for reviewers who had completed the highest quintile of peer reviews (greater than 195) compared with the lowest quintile (one to seven) (adjusted OR 2.85 [2.60-3.12]). Peer review quality differs based on obstetrics and gynecology subspecialty. Obstetrics and gynecology subspecialty and reviewer experience have implications for manuscript rejection recommendation. Reviewer assignment is pivotal to maintaining a rigorous manuscript selection process.

2016-01-01

To investigate the differential emergence of antisocial behaviors and mood dysregulation among children with externalizing problems, the present study prospectively followed 317 high-risk children with early externalizing problems from school entry (ages 5–7) to late adolescence (ages 17–19). Latent class analysis conducted on their conduct and mood symptoms in late adolescence revealed three distinct patterns of symptoms, characterized by: 1) criminal offenses, conduct disorder symptoms, and elevated anger (“conduct problems”), 2) elevated anger, dysphoric mood, and suicidal ideation (“mood dysregulation”), and 3) low levels of severe conduct and mood symptoms. A diathesis-stress model predicting the first two outcomes was tested. Elevated overt aggression at school entry uniquely predicted conduct problems in late adolescence, whereas elevated emotion dysregulation at school entry uniquely predicted mood dysregulation in late adolescence. Experiences of low parental warmth and peer rejection in middle childhood moderated the link between early emotion dysregulation and later mood dysregulation but did not moderate the link between early overt aggression and later conduct problems. Thus, among children with early externalizing behavior problems, increased risk for later antisocial behavior or mood dysfunction may be identifiable in early childhood based on levels of overt aggression and emotion dysregulation. For children with early emotion dysregulation, however, increased risk for mood dysregulation characterized by anger, dysphoric mood, and suicidality – possibly indicative of disruptive mood dysregulation disorder – emerges only in the presence of low parental warmth and/or peer rejection during middle childhood.

2013-01-01

Background ODD is considered to be a disorder of childhood, yet evidence suggests that prevalence rates of the disorder are stable into late adolescence and trajectories of symptoms persist into young adulthood. Functional outcomes associated with ODD through childhood and adolescence include conflict within families, poor peer relationships, peer rejection and academic difficulties. Little examination of functional outcomes in adulthood associated with ODD has been undertaken. Method Data for the present analyses come from a clinic referred sample of 177 boys aged 7 to 12 followed up annually to age 18 and again at age 24. Annual parental report of psychopathology through adolescence was used to predict self-reported functional outcomes at 24. Results Controlling for parent reported symptoms of ADHD, CD, depression and anxiety, ODD symptoms from childhood through adolescence predicted poorer age 24 functioning with peers, poorer romantic relationships, a poorer paternal relationship, and having nobody who would provide a recommendation for a job. CD symptoms predicted workplace problems, poor maternal relationship, lower academic attainment and violent injuries. Only parent reported ODD symptoms and child reported CD symptoms predicted a composite of poor adult outcomes. Conclusion ODD is a disorder that significantly interferes with functioning, particularly in social or interpersonal relationships. The persistence of impairment associated with ODD into young adulthood calls for a reconsideration of ODD as a disorder limited to childhood. PMID:24117754

Parental attention-deficit/hyperactivity disorder predicts child and parent outcomes of parental friendship coaching treatment.

Griggs, Marissa Swaim; Mikami, Amori Yee

2011-12-01

This study investigated the impact of parental attention-deficit/hyperactivity disorder (ADHD) symptoms on the peer relationships and parent-child interaction outcomes of children with ADHD among families completing a randomized controlled trial of parental friendship coaching (PFC) relative to control families. Participants were 62 children with ADHD (42 boys and 20 girls, 6 through 10 years old) and their parents. Approximately half of the families received PFC (a 3-month parent training intervention targeting the peer relationships of children with ADHD), and the remainder represented a no-treatment control group. Parental inattention predicted equivalent declines in children's peer acceptance in both treatment and control families. However, treatment amplified differences between parents with high versus low ADHD symptoms for some outcomes: Control families declined in functioning regardless of parents' symptom levels. However, high parental inattention predicted increased child peer rejection and high parental inattention and impulsivity predicted decreased parental facilitation among treated families (indicating reduced treatment response). Low parental symptoms among treated families were associated with improved functioning in these areas. For other outcomes, treatment attenuated differences between parents with high versus low ADHD symptoms: Among control parents, high parental impulsivity was associated with increasing criticism over time, whereas all treated parents showed reduced criticism regardless of symptom levels. Follow-up analyses indicated that the parents experiencing poor treatment response are likely those with clinical levels of ADHD symptoms. Results underscore the need to consider parental ADHD in parent training treatments for children with ADHD. Copyright © 2011 American Academy of Child and Adolescent Psychiatry.

Adolescence is a sensitive period for the development of romantic relationships. During this period the maturation of frontolimbic networks is particularly important for the capacity to regulate emotional experiences. In previous research, both functional magnetic resonance imaging (fMRI) and dense array electroencephalography (dEEG) measures have suggested that responses in limbic regions are enhanced in adolescents experiencing social rejection. In the present research, we examined social acceptance and rejection from romantic partners as they engaged in a Chatroom Interact Task. Dual 128-channel dEEG systems were used to record neural responses to acceptance and rejection from both adolescent romantic partners and unfamiliar peers (N = 75). We employed a two-step temporal principal component analysis (PCA) and spatial independent component analysis (ICA) approach to statistically identify the neural components related to social feedback. Results revealed that the early (288 ms) discrimination between acceptance and rejection reflected by the P3a component was significant for the romantic partner but not the unfamiliar peer. In contrast, the later (364 ms) P3b component discriminated between acceptance and rejection for both partners and peers. The two-step approach (PCA then ICA) was better able than either PCA or ICA alone in separating these components of the brain's electrical activity that reflected both temporal and spatial phases of the brain's processing of social feedback.

Social Influences on Inequity Aversion in Children

PubMed Central

McAuliffe, Katherine; Blake, Peter R.; Kim, Grace; Wrangham, Richard W.; Warneken, Felix

2013-01-01

Adults and children are willing to sacrifice personal gain to avoid both disadvantageous and advantageous inequity. These two forms of inequity aversion follow different developmental trajectories, with disadvantageous inequity aversion emerging around 4 years and advantageous inequity aversion emerging around 8 years. Although inequity aversion is assumed to be specific to situations where resources are distributed among individuals, the role of social context has not been tested in children. Here, we investigated the influence of two aspects of social context on inequity aversion in 4- to 9-year-old children: (1) the role of the experimenter distributing rewards and (2) the presence of a peer with whom rewards could be shared. Experiment 1 showed that children rejected inequity at the same rate, regardless of whether the experimenter had control over reward allocations. This indicates that children’s decisions are based upon reward allocations between themselves and a peer and are not attempts to elicit more favorable distributions from the experimenter. Experiment 2 compared rejections of unequal reward allocations in children interacting with or without a peer partner. When faced with a disadvantageous distribution, children frequently rejected a smaller reward when a larger reward was visible, even if no partner would obtain the larger reward. This suggests that nonsocial factors partly explain disadvantageous inequity rejections. However, rejections of disadvantageous distributions were higher when the larger amount would go to a peer, indicating that social context enhances disadvantageous inequity aversion. By contrast, children rejected advantageous distributions almost exclusively in the social context. Therefore, advantageous inequity aversion appears to be genuinely social, highlighting its potential relevance for the development of fairness concerns. By comparing social and nonsocial factors, this study provides a detailed picture of the expression of inequity aversion in human ontogeny and raises questions about the function and evolution of inequity aversion in humans.

The heart-break of social rejection versus the brain wave of social acceptance

2014-01-01

The effect of social rejection on cardiac and brain responses was examined in a study in which participants had to decide on the basis of pictures of virtual peers whether these peers would like them or not. Physiological and behavioral responses to expected and unexpected acceptance and rejection were compared. It was found that participants expected that about 50% of the virtual judges gave them a positive judgment. Cardiac deceleration was strongest for unexpected social rejection. In contrast, the brain response was strongest to expected acceptance and was characterized by a positive deflection peaking around 325 ms following stimulus onset and the observed difference was maximal at fronto-central positions. The cardiac and electro-cortical responses were not related. It is hypothesized that these differential response patterns might be related to earlier described differential involvement of the dorsal and ventral portion of the anterior cingulate cortex.

Objective Sexual compulsivity represents a significant public health concern among gay and bisexual men given its co-occurrence with other mental health problems and HIV infection. The purpose of this study was to examine a model of sexual compulsivity based on minority stress theory and emotion regulation models of mental health among gay and bisexual men. Method Gay and bisexual men in New York City reporting at least nine past-90-day sexual partners (n = 374) completed measures of distal minority stressors (i.e., boyhood gender nonconformity and peer rejection, adulthood perceived discrimination), hypothesized proximal minority stress mediators (i.e., rejection sensitivity, internalized homonegativity), hypothesized universal mediators (i.e., emotion dysregulation, depression and anxiety), and sexual compulsivity. Results The hypothesized model fit the data well (RMSEA = 0.05, CFI = 0.98, TLI = 0.95, SRMR = 0.03). Distal minority stress processes (e.g., peer rejection) were generally found to confer risk for both proximal minority stressors (e.g., internalized homonegativity) and emotion dysregulation. Proximal minority stressors and emotion dysregulation, in turn, generally predicted sexual compulsivity both directly and indirectly through anxiety and depression. Conclusions The final model suggests that gay-specific (e.g., internalized homonegativity) and universal (e.g., emotion dysregulation) processes represent potential treatment targets to attenuate the impact of minority stress on gay and bisexual men's sexual health. Tests of interventions that address these targets to treat sexual compulsivity among gay and bisexual men represent a promising future research endeavor. PMID:25528179

Involvement with friends carries many advantages for adolescents, including protection from the detrimental effects of being rejected by peers. However, little is known about the mechanisms through which friendships may serve their protective role at this age, or the potential benefit of these friendships as adolescents transition to adulthood. As such, this investigation tested whether friend involvement during adolescence related to less neural sensitivity to social threats during young adulthood. Twenty-one adolescents reported the amount of time they spent with friends outside of school using a daily diary. Two years later they underwent an fMRI scan, during which they were ostensibly excluded from an online ball-tossing game by two same-age peers. Findings from region of interest and whole brain analyses revealed that spending more time with friends during adolescence related to less activity in the dorsal anterior cingulate cortex and anterior insula--regions previously linked with negative affect and pain processing--during an experience of peer rejection 2 years later. These findings are consistent with the notion that positive relationships during adolescence may relate to individuals being less sensitive to negative social experiences later on.

Kalvin, Carla B.; Bierman, Karen L.; Gatzke-Kopp, Lisa M.

2016-01-01

Prior research suggests that heightened emotional reactivity to emotionally distressing stimuli may be associated with elevated internalizing and externalizing behaviors, and contribute to impaired social functioning. These links were explored in a sample of 169 economically-disadvantaged kindergarteners (66 % male; 68 % African American, 22 % Hispanic, 10 % Caucasian) oversampled for elevated aggression. Physiological measures of emotional reactivity (respiratory sinus arrhythmia [RSA], heart rate [HR], and cardiac pre-ejection period [PEP]) were collected, and teachers and peers provided ratings of externalizing and internalizing behavior, prosocial competence, and peer rejection. RSA withdrawal, HR reactivity, and PEP shortening (indicating increased arousal) were correlated with reduced prosocial competence, and RSA withdrawal and HR reactivity were correlated with elevated internalizing problems. HR reactivity was also correlated with elevated externalizing problems and peer rejection. Linear regressions controlling for age, sex, race, verbal proficiency, and resting physiology showed that HR reactivity explained unique variance in both teacher-rated prosocial competence and peer rejection, and contributed indirectly to these outcomes through pathways mediated by internalizing and externalizing problems. A trend also emerged for the unique contribution of PEP reactivity to peer-rated prosocial competence. These findings support the contribution of emotional reactivity to behavior problems and social adjustment among children living in disadvantaged urban contexts, and further suggest that elevated reactivity may confer risk for social difficulties in ways that overlap only partially with internalizing and externalizing behavior problems.

2015-01-01

Similarities and differences in parenting practices of children (Mage = 10; range 8-13 years) with traumatic brain injury (TBI) and socially-typical controls were examined. In addition, parenting practices were examined as moderators between injury group status (TBI or socially-typical) and social adjustment in the peer group. Mothers completed assessments of parenting practices; children's peers reported about children's social adjustment. The mothers of children with TBI reported significantly lower levels of nurturance and significantly higher levels of restrictiveness than mothers of socially-typical children. In addition, mothers’ nurturance moderated the relation between injury group and peer rejection, such that children with TBI were more rejected by classmates compared to their socially-typical peers at low levels of maternal nurturance. The findings are interpreted as supporting the important role parents play in the development of children with a history of TBI, as well as the implications for family-level interventions.

Cognitive models posit that the fear of negative evaluation (FNE) is a hallmark feature of social anxiety. As such, individuals with high FNE may show biased information processing when faced with social evaluation. The aim of the current study was to examine the neural underpinnings of anticipating and processing social-evaluative feedback, and its correlates with FNE. We used a social judgment paradigm in which female participants (N = 31) were asked to indicate whether they believed to be socially accepted or rejected by their peers. Anticipatory attention was indexed by the stimulus preceding negativity (SPN), while the feedback-related negativity and P3 were used to index the processing of social-evaluative feedback. Results provided evidence of an optimism bias in social peer evaluation, as participants more often predicted to be socially accepted than rejected. Participants with high levels of FNE needed more time to provide their judgments about the social-evaluative outcome. While anticipating social-evaluative feedback, SPN amplitudes were larger for anticipated social acceptance than for social rejection feedback. Interestingly, the SPN during anticipated social acceptance was larger in participants with high levels of FNE. None of the feedback-related brain potentials correlated with the FNE. Together, the results provided evidence of biased information processing in individuals with high levels of FNE when anticipating (rather than processing) social-evaluative feedback. The delayed response times in high FNE individuals were interpreted to reflect augmented vigilance imposed by the upcoming social-evaluative threat. Possibly, the SPN constitutes a neural marker of this vigilance in females with higher FNE levels, particularly when anticipating social acceptance feedback.

In this longitudinal study, attributional and social processes involved in symptoms of mental health problems (depressive symptoms and aggressive behavior) were identified by investigating anxious and angry rejection sensitivity (RS), causal attributions of self-blame and peer-blame, and responses to rejection threat of withdrawal and retribution. Young adolescents (N = 713, grades 5-7) completed questionnaires three times in their regular classrooms over 14 months. Participants who reported more self-blame for rejection were more likely to withdraw in response to rejection threat, and withdrawal and anxious RS were associated with increased depressive symptoms at T3 relative to T1. In contrast, adolescents higher in the angry form of RS and who reported more peer-blame for rejection were more likely to seek retribution, which in turn was associated with more overt/relational aggressive behavior at T3 relative to T1. Depressive symptom level measured at T1 also was associated with later RS and coping with withdrawal, and aggressive behavior at T1 was associated with later retribution. Sex of the participants did not moderate any longitudinal associations, and only one prospective path, from T1 depressive symptoms to T2 RS anxious, was moderated by age.

Prior research suggests that heightened emotional reactivity to emotionally distressing stimuli may be associated with elevated internalizing and externalizing behaviors, and contribute to impaired social functioning. These links were explored in a sample of 169 economically-disadvantaged kindergarteners (66 % male; 68 % African American, 22 % Hispanic, 10 % Caucasian) oversampled for elevated aggression. Physiological measures of emotional reactivity (respiratory sinus arrhythmia [RSA], heart rate [HR], and cardiac pre-ejection period [PEP]) were collected, and teachers and peers provided ratings of externalizing and internalizing behavior, prosocial competence, and peer rejection. RSA withdrawal, HR reactivity, and PEP shortening (indicating increased arousal) were correlated with reduced prosocial competence, and RSA withdrawal and HR reactivity were correlated with elevated internalizing problems. HR reactivity was also correlated with elevated externalizing problems and peer rejection. Linear regressions controlling for age, sex, race, verbal proficiency, and resting physiology showed that HR reactivity explained unique variance in both teacher-rated prosocial competence and peer rejection, and contributed indirectly to these outcomes through pathways mediated by internalizing and externalizing problems. A trend also emerged for the unique contribution of PEP reactivity to peer-rated prosocial competence. These findings support the contribution of emotional reactivity to behavior problems and social adjustment among children living in disadvantaged urban contexts, and further suggest that elevated reactivity may confer risk for social difficulties in ways that overlap only partially with internalizing and externalizing behavior problems.

Peer review and competition in the Art Exhibition Game.

To investigate the effect of competitive incentives under peer review, we designed a novel experimental setup called the Art Exhibition Game. We present experimental evidence of how competition introduces both positive and negative effects when creative artifacts are evaluated and selected by peer review. Competition proved to be a double-edged sword: on the one hand, it fosters innovation and product diversity, but on the other hand, it also leads to more unfair reviews and to a lower level of agreement between reviewers. Moreover, an external validation of the quality of peer reviews during the laboratory experiment, based on 23,627 online evaluations on Amazon Mechanical Turk, shows that competition does not significantly increase the level of creativity. Furthermore, the higher rejection rate under competitive conditions does not improve the average quality of published contributions, because more high-quality work is also rejected. Overall, our results could explain why many ground-breaking studies in science end up in lower-tier journals. Differences and similarities between the Art Exhibition Game and scholarly peer review are discussed and the implications for the design of new incentive systems for scientists are explained.

Childhood Conduct Problems and Young Adult Outcomes Among Women with Childhood ADHD

Owens, Elizabeth B.; Hinshaw, Stephen P.

2015-01-01

We tested whether conduct problems predicted young adult functioning and psychiatric symptoms among women diagnosed with ADHD during childhood, in the context of three potential adolescent mediators: internalizing problems, peer rejection, and school failure and disciplinary problems. We controlled for childhood ADHD severity, IQ, and demographic factors, and in the mediational tests, for adolescent conduct problems. Data emanated from 140 participants in the Berkeley Girls with ADHD Longitudinal Study. We used bootstrapping methods to assess indirect effects (mediators). Both childhood (F1,118 change = 9.00, p = .003, R2 change = .069) and adolescent (F1,109 change = 10.41, p = .002, R2 change = .083) conduct problems were associated with worse overall functioning during young adulthood, controlling for initial ADHD severity, child IQ, and demographics. Results were similar when predicting psychiatric symptoms. Adolescent school failure and disciplinary problems mediated the relations between childhood conduct problems and both young-adult functioning and externalizing problems; adolescent internalizing problems and peer conflict mediated the relation between childhood conduct problems and young-adult internalizing problems. As is true for boys, childhood and adolescent conduct problems are associated with poor adult outcomes among girls with ADHD, with school failure and disciplinary problems, internalizing problems, and peer conflict functioning as mediators of these relations.

Festa, Candice C; Ginsburg, Golda S

2011-06-01

The aim of the current study was to extend etiological models of social anxiety in youth by examining the relative importance of parental (i.e., parental anxiety, rejection, and overcontrol) and peer factors (i.e., social acceptance, social support, and friendship quality). Sixty-three youth (ages 7–12; 52% male) and their parents participated in the study. Using multiple informants of these factors, results generally indicated that higher levels of parental anxiety, rejection, and overcontrol were related to higher levels of social anxiety. Higher levels of social support, acceptance, and validation were associated with lower levels social anxiety. The strongest predictors of social anxiety symptoms (as rated by an independent evaluator) were parental anxiety and friendship quality (i.e., validation from a peer). The strongest predictors of child rated social anxiety symptoms were parental overcontrol and perceived social acceptance. Findings are discussed in the context of current etiological models and suggest that interventions aimed at lowering social anxiety in youth address both parental anxiety and peer relationships.

Publishing is critical for academic medicine career advancement. Rejection of manuscripts can be demoralizing. Obstacles faced by clinical faculty may include lack of time, confidence, and optimal writing practices. This study describes the development and evaluation of a peer-writing group, informed by theory and research on faculty development and writing. Five clinical-track radiology faculty members formed a "Writers' Circle" to promote scholarly productivity and reflection on writing practices. Members decided to work with previously rejected manuscripts. After members' initial meeting, interactions were informal, face to face during clinical work, and online. After the first 6 months, an anonymous survey asked members about the status of articles and evaluations of the writing group. Ten previously rejected articles, at least one from each member, were submitted to the Circle. In 6 months, four manuscripts were accepted for publication, five were in active revision, and one was withdrawn. All participants (100%) characterized the program as worth their time, increasing their motivation to write, their opportunities to support scholarly productivity of colleagues, and their confidence in generating scholarship. Peer-support writing groups can facilitate the pooling of expertise and the exchange of recommended writing practices. Our peer-support group increased scholarly productivity and provided a collegial approach to academic writing. Copyright © 2015 AUR. Published by Elsevier Inc. All rights reserved.

Longitudinal links between childhood peer acceptance and the neural correlates of sharing.

2018-01-01

Childhood peer acceptance is associated with high levels of prosocial behavior and advanced perspective taking skills. Yet, the neurobiological mechanisms underlying these associations have not been studied. This functional magnetic resonance imaging study examined the neural correlates of sharing decisions in a group of adolescents who had a stable accepted status (n = 27) and a group who had a chronic rejected status (n = 19) across six elementary school grades. Both groups of adolescents played three allocation games in which they could share money with strangers with varying costs and profits to them and the other person. Stably accepted adolescents were more likely to share their money with unknown others than chronically rejected adolescents when sharing was not costly. Neuroimaging analyses showed that stably accepted adolescents, compared to chronically rejected adolescents, exhibited higher levels of activation in the temporo-parietal junction, posterior superior temporal sulcus, temporal pole, pre-supplementary motor area, and anterior insula during costly sharing decisions. These findings demonstrate that stable peer acceptance across childhood is associated with heightened activity in brain regions previously linked to perspective taking and the detection of social norm violations during adolescence, and thereby provide insight into processes underlying the widely established links between peer acceptance and prosocial behavior. © 2016 The Authors.

Behavioral inhibition (BI) is a temperament characterized by social reticence and withdrawal from unfamiliar or novel contexts and conveys risk for social anxiety disorder. Developmental outcomes associated with this temperament can be influenced by children's caregiving context. The convergence of a child's temperamental disposition and rearing environment is ultimately expressed at both the behavioral and neural levels in emotional and cognitive response patterns to social challenges. The present study used functional neuroimaging to assess the moderating effects of different parenting styles on neural response to peer rejection in two groups of adolescents characterized by their early childhood temperament (M(age) = 17.89 years, N = 39, 17 males, 22 females; 18 with BI; 21 without BI). The moderating effects of authoritarian and authoritative parenting styles were examined in three brain regions linked with social anxiety: ventrolateral prefrontal cortex (vlPFC), striatum, and amygdala. In youth characterized with BI in childhood, but not in those without BI, diminished responses to peer rejection in vlPFC were associated with higher levels of authoritarian parenting. In contrast, all youth showed decreased caudate response to peer rejection at higher levels of authoritative parenting. These findings indicate that BI in early life relates to greater neurobiological sensitivity to variance in parenting styles, particularly harsh parenting, in late adolescence. These results are discussed in relation to biopsychosocial models of development.

Functional outcomes of child and adolescent oppositional defiant disorder symptoms in young adult men.

PubMed

Burke, Jeffrey D; Rowe, Richard; Boylan, Khrista

2014-03-01

Oppositional defiant disorder(ODD) is considered to be a disorder of childhood, yet evidence suggests that prevalence rates of the disorder are stable into late adolescence and trajectories of symptoms persist into young adulthood. Functional outcomes associated with ODD through childhood and adolescence include conflict within families, poor peer relationships, peer rejection, and academic difficulties. Little examination of functional outcomes in adulthood associated with ODD has been undertaken. Data for the present analyses come from a clinic referred sample of 177 boys aged 7-12 followed up annually to age 18 and again at age 24. Annual parental report of psychopathology through adolescence was used to predict self-reported functional outcomes at 24. Controlling for parent reported symptoms of attention deficit hyperactivity disorder (ADHD), Conduct disorder (CD), depression and anxiety, ODD symptoms from childhood through adolescence predicted poorer age 24 functioning with peers, poorer romantic relationships, a poorer paternal relationship, and having nobody who would provide a recommendation for a job. CD symptoms predicted workplace problems, poor maternal relationship, lower academic attainment, and violent injuries. Only parent reported ODD symptoms and child reported CD symptoms predicted a composite of poor adult outcomes. Oppositional defiant disorder is a disorder that significantly interferes with functioning, particularly in social or interpersonal relationships. The persistence of impairment associated with ODD into young adulthood calls for a reconsideration of ODD as a disorder limited to childhood. © 2013 The Authors.

Despite significant social difficulties, children with autism spectrum disorder (ASD) are vulnerable to the effects of social exclusion. We recorded EEG while children with ASD and typical peers played a computerized game involving peer rejection. Children with ASD reported ostracism-related distress comparable to typically developing children. Event-related potentials (ERPs) indicated a distinct pattern of temporal processing of rejection events in children with ASD. While typically developing children showed enhanced response to rejection at a late slow wave indexing emotional arousal and regulation, those with autism showed attenuation at an early component, suggesting reduced engagement of attentional resources in the aversive social context. Results emphasize the importance of studying the time course of social information processing in ASD; they suggest distinct mechanisms subserving similar overt behavior and yield insights relevant to development and implementation of targeted treatment approaches and objective measures of response to treatment.

Emotional, Cognitive and Self-Enhancement Processes in Aggressive Behavior After Interpersonal Rejection and Exclusion.

PubMed

Rajchert, Joanna

2015-11-01

The relationship between exclusion or rejection and aggression is already well documented, but there is still a debate about the mechanisms that underlie this effect. In two studies we focused on the propensity to react aggressively (readiness for aggression) on the bases of emotional, cognitive or self-enhancement (personality-immanent) processes. In both studies we first measured readiness for aggression and then ego-depleted participants. Next, in Study 1 we excluded participants (n = 96) using an online ball throwing game and measured displaced aggressive behavior - intensity and duration of an unpleasant noise administrated to a stranger. In Study 2 participants (n = 140) were rejected by a peer on the basis of an interview that they gave and then could retaliate by reducing peer's chance for getting a job. The results show that exclusion effect on displaced aggression was moderated by cognitive readiness for aggression, while rejection effect on retaliatory aggression was shaped by emotional and personality-immanent readiness for aggression as well as ego-depletion. The results were discussed in light of the strength model of self-control by Baumeister, Vohs, and Tice (2007).

Complex systems approach to scientific publication and peer-review system: development of an agent-based model calibrated with empirical journal data.

PubMed

Kovanis, Michail; Porcher, Raphaël; Ravaud, Philippe; Trinquart, Ludovic

Scientific peer-review and publication systems incur a huge burden in terms of costs and time. Innovative alternatives have been proposed to improve the systems, but assessing their impact in experimental studies is not feasible at a systemic level. We developed an agent-based model by adopting a unified view of peer review and publication systems and calibrating it with empirical journal data in the biomedical and life sciences. We modeled researchers, research manuscripts and scientific journals as agents. Researchers were characterized by their scientific level and resources, manuscripts by their scientific value, and journals by their reputation and acceptance or rejection thresholds. These state variables were used in submodels for various processes such as production of articles, submissions to target journals, in-house and external peer review, and resubmissions. We collected data for a sample of biomedical and life sciences journals regarding acceptance rates, resubmission patterns and total number of published articles. We adjusted submodel parameters so that the agent-based model outputs fit these empirical data. We simulated 105 journals, 25,000 researchers and 410,000 manuscripts over 10 years. A mean of 33,600 articles were published per year; 19 % of submitted manuscripts remained unpublished. The mean acceptance rate was 21 % after external peer review and rejection rate 32 % after in-house review; 15 % publications resulted from the first submission, 47 % the second submission and 20 % the third submission. All decisions in the model were mainly driven by the scientific value, whereas journal targeting and persistence in resubmission defined whether a manuscript would be published or abandoned after one or many rejections. This agent-based model may help in better understanding the determinants of the scientific publication and peer-review systems. It may also help in assessing and identifying the most promising alternative systems of peer review.

Variability of Reviewers' Comments in the Peer Review Process for Orthopaedic Research.

Retrospective analysis of peer review comments. To assess the likelihood that comments provided by peer reviewers of one orthopaedic journal would be similar to comments of reviewers from the same journal and a second journal. The consistency of the peer review process in orthopedic research has not been objectively examined. Nine separate clinical papers related to spinal deformity were submitted for publication in major peer-reviewed journals and initially rejected. The exact same manuscripts were then submitted to different journals. All papers were returned with comments from two to three reviewers from each journal. Reviews were divided into distinct conceptual criticisms that were regarded as separate comments. Comments were compared between reviewers of the same journal and to comments from reviewers of the second journal. When comparing comments from reviewers of the same journal, an average of 11% of comments were repeated (range 0% [0/12] to 23% [3/13]). On average, 20% of comments from the first journal were repeated by a reviewer at the second journal (range 10% [1/10] to 33% [6/18]). If a comment was made by two or more reviewers from the first journal, it had a higher likelihood (43% [6/14]) of being repeated by a reviewer from the second journal. When an identical manuscript is submitted to a second journal after being rejected, 80% of peer review comments from the first journal are not repeated by reviewers from the second journal. One may question if addressing every peer review comment in a rejected manuscript prior to resubmission is an efficient use of resources. Comments that appear twice or more in the first journal review are more likely to reappear and may warrant special attention from the researcher. Level IV.

Cognitive models posit that the fear of negative evaluation (FNE) is a hallmark feature of social anxiety. As such, individuals with high FNE may show biased information processing when faced with social evaluation. The aim of the current study was to examine the neural underpinnings of anticipating and processing social-evaluative feedback, and its correlates with FNE. We used a social judgment paradigm in which female participants (N = 31) were asked to indicate whether they believed to be socially accepted or rejected by their peers. Anticipatory attention was indexed by the stimulus preceding negativity (SPN), while the feedback-related negativity and P3 were used to index the processing of social-evaluative feedback. Results provided evidence of an optimism bias in social peer evaluation, as participants more often predicted to be socially accepted than rejected. Participants with high levels of FNE needed more time to provide their judgments about the social-evaluative outcome. While anticipating social-evaluative feedback, SPN amplitudes were larger for anticipated social acceptance than for social rejection feedback. Interestingly, the SPN during anticipated social acceptance was larger in participants with high levels of FNE. None of the feedback-related brain potentials correlated with the FNE. Together, the results provided evidence of biased information processing in individuals with high levels of FNE when anticipating (rather than processing) social-evaluative feedback. The delayed response times in high FNE individuals were interpreted to reflect augmented vigilance imposed by the upcoming social-evaluative threat. Possibly, the SPN constitutes a neural marker of this vigilance in females with higher FNE levels, particularly when anticipating social acceptance feedback. PMID:24478667

Social Withdrawal in Childhood

2013-01-01

Socially withdrawn children frequently refrain from social activities in the presence of peers. The lack of social interaction in childhood may result from a variety of causes, including social fear and anxiety or a preference for solitude. From early childhood through to adolescence, socially withdrawn children are concurrently and predictively at risk for a wide range of negative adjustment outcomes, including socio-emotional difficulties (e.g., anxiety, low self-esteem, depressive symptoms, and internalizing problems), peer difficulties (e.g., rejection, victimization, poor friendship quality), and school difficulties (e.g., poor-quality teacher-child relationships, academic difficulties, school avoidance). The goals of the current review are to (a) provide some definitional, theoretical, and methodological clarity to the complex array of terms and constructs previously employed in the study of social withdrawal; (b) examine the predictors, correlates, and consequences of child and early-adolescent social withdrawal; and (c) present a developmental framework describing pathways to and from social withdrawal in childhood.

Delinquency as a mediator of the relation between negative affectivity and adolescent alcohol use disorder.

Shoal, Gavin D; Gudonis, Lauren C; Giancola, Peter R; Tarter, Ralph E

2007-12-01

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.

Background Publishing in scientific journals is one of the most important ways in which scientists disseminate research to their peers and to the wider public. Pre-publication peer review underpins this process, but peer review is subject to various criticisms and is under pressure from growth in the number of scientific publications. Methods Here we examine an element of the editorial process at eLife , in which the Reviewing Editor usually serves as one of the referees, to see what effect this has on decision times, decision type, and the number of citations. We analysed a dataset of 8,905 research submissions to eLife since June 2012, of which 2,747 were sent for peer review. This subset of 2747 papers was then analysed in detail.   Results The Reviewing Editor serving as one of the peer reviewers results in faster decision times on average, with the time to final decision ten days faster for accepted submissions (n=1,405) and five days faster for papers that were rejected after peer review (n=1,099). Moreover, editors acting as reviewers had no effect on whether submissions were accepted or rejected, and a very small (but significant) effect on citation rates. Conclusions An important aspect of eLife 's peer-review process is shown to be effective, given that decision times are faster when the Reviewing Editor serves as a reviewer. Other journals hoping to improve decision times could consider adopting a similar approach.

A cross-national comparison of aggressors, victims and defenders in preschools in England, Spain and Italy.

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.

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

Childhood conduct problems and young adult outcomes among women with childhood attention-deficit/hyperactivity disorder (ADHD).

PubMed

Owens, Elizabeth B; Hinshaw, Stephen P

2016-02-01

We tested whether conduct problems predicted young adult functioning and psychiatric symptoms among women diagnosed with attention-deficit/hyperactivity disorder (ADHD) during childhood, in the context of 3 potential adolescent mediators: internalizing problems, peer rejection, and school failure and disciplinary problems. We controlled for childhood ADHD severity, IQ, and demographic factors, and in the mediational tests, for adolescent conduct problems. Data came from 140 participants in the Berkeley Girls With ADHD Longitudinal Study. We used bootstrapping methods to assess indirect effects (mediators). Both childhood, F(1, 118) change = 9.00, p = .003, R2 change = .069, and adolescent, F(1, 109) change = 10.41, p = .002, R2 change = .083, conduct problems were associated with worse overall functioning during young adulthood, controlling for initial ADHD severity, child IQ, and demographics. Results were similar when predicting psychiatric symptoms. Adolescent school failure and disciplinary problems mediated the relations between childhood conduct problems and both young adult functioning and externalizing problems; adolescent internalizing problems and peer conflict mediated the relation between childhood conduct problems and young adult internalizing problems. As is true for boys, childhood and adolescent conduct problems are associated with poor adult outcomes among girls with ADHD, with school failure and disciplinary problems, internalizing problems, and peer conflict functioning as mediators of these relations.

Emotional, Cognitive and Self-Enhancement Processes in Aggressive Behavior After Interpersonal Rejection and Exclusion

PubMed Central

Rajchert, Joanna

2015-01-01

The relationship between exclusion or rejection and aggression is already well documented, but there is still a debate about the mechanisms that underlie this effect. In two studies we focused on the propensity to react aggressively (readiness for aggression) on the bases of emotional, cognitive or self-enhancement (personality-immanent) processes. In both studies we first measured readiness for aggression and then ego-depleted participants. Next, in Study 1 we excluded participants (n = 96) using an online ball throwing game and measured displaced aggressive behavior - intensity and duration of an unpleasant noise administrated to a stranger. In Study 2 participants (n = 140) were rejected by a peer on the basis of an interview that they gave and then could retaliate by reducing peer's chance for getting a job. The results show that exclusion effect on displaced aggression was moderated by cognitive readiness for aggression, while rejection effect on retaliatory aggression was shaped by emotional and personality-immanent readiness for aggression as well as ego-depletion. The results were discussed in light of the strength model of self-control by Baumeister, Vohs, and Tice (2007). PMID:27247687

Social involvement of children with autism spectrum disorders in elementary school classrooms.

2010-11-01

Children with autism spectrum disorders (ASD) are increasingly included in general education classrooms in an effort to improve their social involvement. Seventy-nine children with ASD and 79 randomly selected, gender-matched peers (88.6% male) in 75 early (K-1), middle (2nd-3rd), and late (4th-5th) elementary classrooms across 30 schools completed social network surveys examining each child's reciprocal friendships, peer rejection, acceptance, and social involvement. Across grade levels, peers less frequently reciprocated friendships with children with ASD than students in the matched sample. While children with ASD were not more likely to be rejected by peers, they were less accepted and had fewer reciprocal friendships than matched peers at each grade level. Although 48.1% of children with ASD were involved in the social networks of their classrooms, children with ASD were more likely to be isolated or peripheral to social relationships within the classroom across all grade levels, and this difference is even more dramatic in later elementary grades. In inclusive classrooms, children with ASD are only involved in peers' social relationships about half of the time, and appear to be even less connected with increasing grade level. Promoting children with ASD's skills in popular activities to share with peers in early childhood may be a key preventive intervention to protect social relationships in late elementary school grades. © 2010 The Authors.

Does perceived parental rejection make adolescents sad and mad? The association of perceived parental rejection with adolescent depression and aggression.

PubMed

Hale, William W; Van Der Valk, Inge; Engels, Rutger; Meeus, Wim

2005-06-01

To research the association of perceived parental rejection to adolescent depression and aggression. This study focused on 1329 Dutch junior high and high school students (47.9% males and 52.1% females; age range 10-19 years) that completed depression, aggression and perceived parental rejection questionnaires. The data were analyzed by structural equation modeling that assumed a relationship between perceived parental rejection and adolescent aggression, as mediated by adolescent depression. Perceived parental rejection, mediated through adolescent depression, explains aggressive behaviors of adolescents, as tested by a mediation model. Additionally, the fit of this mediation model is somewhat enhanced when direct paths from perceived parental rejection to aggression are included. Further analysis demonstrates that these effects are also somewhat dependent on the gender and the age of the adolescents, as would be expected in light of previous studies of these cohorts. The study of perceived parental rejection should receive the same attention in the research of the development of both adolescent depression and aggression, as has been the case for adolescent peer rejection.

Rejection sensitivity prospectively predicts increased rumination.

PubMed

Pearson, Katherine A; Watkins, Edward R; Mullan, Eugene G

2011-10-01

Converging research findings indicate that rumination is correlated with a specific maladaptive interpersonal style encapsulating submissive (overly-accommodating, non-assertive and self-sacrificing) behaviours, and an attachment orientation characterised by rejection sensitivity. This study examined the prospective longitudinal relationship between rumination, the submissive interpersonal style, and rejection sensitivity by comparing two alternative hypotheses: (a) the submissive interpersonal style and rejection sensitivity prospectively predict increased rumination; (b) rumination prospectively predicts the submissive interpersonal style and rejection sensitivity. Currently depressed (n = 22), previously depressed (n = 42) and never depressed (n = 28) individuals completed self-report measures assessing depressive rumination and key psychosocial measures of interpersonal style and behaviours, at baseline and again six months later. Baseline rejection sensitivity prospectively predicted increased rumination six months later, after statistically controlling for baseline rumination, gender and depression. Baseline rumination did not predict the submissive interpersonal style or rejection sensitivity. The results provide a first step towards delineating a potential casual relationship between rejection sensitivity and rumination, and suggest the potential value of clinical assessment and intervention for both rejection sensitivity and rumination in individuals who present with either difficulty.

Is costly punishment altruistic? Exploring rejection of unfair offers in the Ultimatum Game in real-world altruists

PubMed Central

Brethel-Haurwitz, Kristin M.; Stoycos, Sarah A.; Cardinale, Elise M.; Huebner, Bryce; Marsh, Abigail A.

2016-01-01

In the Ultimatum Game (UG), incurring a cost to punish inequity is commonly termed altruistic punishment. This behaviour is thought to benefit others if the defector becomes more equitable in future interactions. However, clear connections between punishment in the UG and altruistic behaviours outside the laboratory are lacking. We tested the altruistic punishment hypothesis in a sample of extraordinarily altruistic adults, predicting that if punishing inequity is predictive of altruism more broadly, extraordinary altruists should punish more frequently. Results showed that punishment was not more prevalent in extraordinary altruists than controls. However, a self-reported altruism measure previously linked to peer evaluations but not behaviour, and on which extraordinary altruists and controls did not differ, did predict punishment. These findings support suggestions that altruistic punishment in the UG is better termed costly punishment and may be motivated by social, but not necessarily prosocial, concerns. Results also support prior suggestions that self-reported altruism may not reliably predict altruistic behaviour. PMID:26739364

2017-02-01

This paper aims at providing a statistical model for the preferred behavior of authors submitting a paper to a scientific journal. The electronic submission of (about 600) papers to the Journal of the Serbian Chemical Society has been recorded for every day from Jan. 01, 2013 till Dec. 31, 2014, together with the acceptance or rejection paper fate. Seasonal effects and editor roles (through desk rejection and subfield editors) are examined. An ARCH-like econometric model is derived stressing the main determinants of the favorite day-of-week process.

Delinquency as a Mediator of the Relation between Negative Affectivity and Adolescent Alcohol Use Disorder

PubMed Central

Shoal, Gavin D.; Gudonis, Lauren C.; Giancola, Peter R.; Tarter, Ralph E.

2007-01-01

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

Does the Committee Peer Review Select the Best Applicants for Funding? An Investigation of the Selection Process for Two European Molecular Biology Organization Programmes

PubMed Central

Bornmann, Lutz; Wallon, Gerlind; Ledin, Anna

2008-01-01

Does peer review fulfill its declared objective of identifying the best science and the best scientists? In order to answer this question we analyzed the Long-Term Fellowship and the Young Investigator programmes of the European Molecular Biology Organization. Both programmes aim to identify and support the best post doctoral fellows and young group leaders in the life sciences. We checked the association between the selection decisions and the scientific performance of the applicants. Our study involved publication and citation data for 668 applicants to the Long-Term Fellowship programme from the year 1998 (130 approved, 538 rejected) and 297 applicants to the Young Investigator programme (39 approved and 258 rejected applicants) from the years 2001 and 2002. If quantity and impact of research publications are used as a criterion for scientific achievement, the results of (zero-truncated) negative binomial models show that the peer review process indeed selects scientists who perform on a higher level than the rejected ones subsequent to application. We determined the extent of errors due to over-estimation (type I errors) and under-estimation (type 2 errors) of future scientific performance. Our statistical analyses point out that between 26% and 48% of the decisions made to award or reject an application show one of both error types. Even though for a part of the applicants, the selection committee did not correctly estimate the applicant's future performance, the results show a statistically significant association between selection decisions and the applicants' scientific achievements, if quantity and impact of research publications are used as a criterion for scientific achievement.

What Does It Take to Change an Editor's Mind? Identifying Minimally Important Difference Thresholds for Peer Reviewer Rating Scores of Scientific Articles.

PubMed

Callaham, Michael; John, Leslie K

2018-01-05

We define a minimally important difference for the Likert-type scores frequently used in scientific peer review (similar to existing minimally important differences for scores in clinical medicine). The magnitude of score change required to change editorial decisions has not been studied, to our knowledge. Experienced editors at a journal in the top 6% by impact factor were asked how large a change of rating in "overall desirability for publication" was required to trigger a change in their initial decision on an article. Minimally important differences were assessed twice for each editor: once assessing the rating change required to shift the editor away from an initial decision to accept, and the other assessing the magnitude required to shift away from an initial rejection decision. Forty-one editors completed the survey (89% response rate). In the acceptance frame, the median minimally important difference was 0.4 points on a scale of 1 to 5. Editors required a greater rating change to shift from an initial rejection decision; in the rejection frame, the median minimally important difference was 1.2 points. Within each frame, there was considerable heterogeneity: in the acceptance frame, 38% of editors did not change their decision within the maximum available range; in the rejection frame, 51% did not. To our knowledge, this is the first study to determine the minimally important difference for Likert-type ratings of research article quality, or in fact any nonclinical scientific assessment variable. Our findings may be useful for future research assessing whether changes to the peer review process produce clinically meaningful differences in editorial decisionmaking.

Who benefits from peer review? An analysis of the outcome of 100 requests for review by Plastic and Reconstructive Surgery.

PubMed

Loonen, Martijn P J; Hage, J Joris; Kon, Moshe

2005-10-01

Little is known of what is done with the comments on submitted manuscripts provided by peer reviewers or to what extent these comments benefit the editor in deciding to accept or reject the manuscript, the author(s) in revising their manuscript, or the readership at large. Furthermore, nothing is known of any possible benefits of the process to the peer reviewer. Finally, the peer-review process may even be maleficent because of its implicit delay of publication and a possible bias against manuscripts originating from non-Anglo-American countries. The authors evaluated the benefits of the peer-review process to authors, editor, readers, and reviewers by a bibliometric analysis of the outcome of 100 requests for review made by the editor of Plastic and Reconstructive Surgery from 1992 through 2003. The publication delay and potential geographical bias were evaluated as potential disadvantages. The authors' reviewer advised acceptance of 56 percent of the manuscripts, and the editor mostly agreed with his advice. This suggests that the editor benefited from the review. The authors addressed 48 to 81 percent of the reviewer's constructive suggestions, and this suggests that they and the readers benefited also. Readers of Plastic and Reconstructive Surgery may further benefit because manuscripts rejected by Plastic and Reconstructive Surgery end up in less prestigious journals. The implicit delay of publication is limited, and the authors found no bias against non-Anglo-American submissions. The cost-effectiveness of the process for the peer reviewer remains unclear. The peer-review system of Plastic and Reconstructive Surgery, in general, is beneficial.

Growth in Temperament and Parenting as Predictors of Adjustment During Children’s Transition to Adolescence

PubMed Central

Lengua, Liliana J.

2014-01-01

The author examined relations among demographic risk (income, maternal education, single-parent status), growth in temperament (fear, irritability, effortful control), and parenting (rejection, inconsistent discipline) across 3 years and the prediction of children’s adjustment problems in a community sample (N = 190; ages 8–12 years at Time 1). Family income was related to higher initial levels of fear, irritability, rejection, and inconsistency and lower effortful control but was not related to changes in these variables. Higher initial rejection predicted increases in child fear and irritability. Higher initial fear predicted decreases in rejection and inconsistency. Higher initial irritability predicted increases in inconsistency, and higher initial effortful control predicted decreases in rejection. When growth of parenting and temperament were considered simultaneously, increases in effortful control and decreases in fear and irritability predicted lower Time 3 internalizing and externalizing problems. Increases in rejection and inconsistent discipline predicted higher Time 3 externalizing, although sometimes the effect appeared to be indirect through temperament. The findings suggest that temperament and parenting predict changes in each other and predict adjustment during the transition to adolescence. PMID:16953689

Common oxytocin receptor gene variant interacts with rejection sensitivity to influence cortisol reactivity during negative evaluation.

Auer, Brandon J; Byrd-Craven, Jennifer; Grant, DeMond M; Granger, Douglas A

2015-09-01

The study tested the hypothesis that variation in the oxytocin receptor gene (OXTR rs53576) and self-report of rejection sensitivity are associated with adrenocortical reactivity to social stress. Participants (N=94; 36.17% male; Mage=20.18yrs; 62.8% Caucasian) completed a writing task on a salient problem in society, provided self-report via questionnaire of rejection sensitivity, and were then informed that a committee of peers would evaluate their written comments. Participants received either scripted praise or criticism as a way to induce social evaluative threat. Saliva was collected before and after the stress task and assayed for cortisol. Results revealed that cortisol levels increased in participants with moderate levels of social rejection sensitivity-inferred by rs53576 genotype and reported rejection sensitivity-while cortisol levels decreased in participants with high and low levels of social rejection sensitivity. Our findings suggest a curvilinear relationship between social rejection sensitivity and cortisol reactivity in the context of social rejection, warranting further consideration in future studies.

Delighted when approved by others, to pieces when rejected: children's social anxiety magnifies the linkage between self- and other-evaluations.

2011-07-01

Socially anxious children tend to attach great importance to others' evaluations of them. However, the extent to which they base their momentary feelings of self-worth (i.e., state self-esteem) on social (dis)approval is unclear. It is also unclear whether this exceedingly approval-based self-esteem is a common correlate of social anxiety and depression, or specifically linked to one or the other. Changes in children's state self-esteem were obtained in response to a manipulated peer evaluation outcome. Participants (N = 188) aged 10 to 13 took part in a rigged online computer contest and were randomized to receive positive or negative peer feedback. Self-reported state self-esteem was assessed via computer at baseline and immediately post-feedback. The predictive effects of self-reported social anxiety and depression symptoms on changes in state self-esteem were investigated. Hierarchical multiple regression analyses showed that children with higher social anxiety, as indexed by the fear of negative evaluation component, experienced significantly stronger increases in state self-esteem following peer approval (β = .26, p < .05), and significantly stronger decreases in state self-esteem following peer disapproval (β = -.23, p < .05). In both conditions depressive symptoms did not predict changes in state self-esteem (ps > .20). Socially anxious children's state self-esteem is strongly contingent on social approval. Because basing one's self-esteem on external validation has multiple negative consequences, these findings highlight the importance of teaching these children skills (e.g., making cognitive reappraisals) to weaken the linkage between other- and self-evaluations. © 2010 The Authors.

The relationship between manuscript title structure and success: editorial decisions and citation performance for an ecological journal

PubMed Central

Fox, Charles W; Burns, C Sean

2015-01-01

A poorly chosen article title may make a paper difficult to discover or discourage readership when discovered, reducing an article's impact. Yet, it is unclear how the structure of a manuscript's title influences readership and impact. We used manuscript tracking data for all manuscripts submitted to the journal Functional Ecology from 2004 to 2013 and citation data for papers published in this journal from 1987 to 2011 to examine how title features changed and whether a manuscript's title structure was predictive of success during the manuscript review process and/or impact (citation) after publication. Titles of manuscripts submitted to Functional Ecology became marginally longer (after controlling for other variables), broader in focus (less frequent inclusion of genus and species names), and included more humor and subtitles over the period of the study. Papers with subtitles were less likely to be rejected by editors both pre- and post-peer review, although both effects were small and the presence of subtitles in published papers was not predictive of citations. Papers with specific names of study organisms in their titles fared poorly during editorial (but not peer) review and, if published, were less well cited than papers whose titles did not include specific names. Papers with intermediate length titles were more successful during editorial review, although the effect was small and title word count was not predictive of citations. No features of titles were predictive of reviewer willingness to review papers or the length of time a paper was in peer review. We conclude that titles have changed in structure over time, but features of title structure have only small or no relationship with success during editorial review and post-publication impact. The title feature that was most predictive of manuscript success: papers whose titles emphasize broader conceptual or comparative issues fare better both pre- and post-publication than do papers with organism-specific titles.

Papers with subtitles were less likely to be rejected by editors both pre- and post-peer review, although both effects were small and the presence of subtitles in published papers was not predictive of citations. Papers with specific names of study organisms in their titles fared poorly during editorial (but not peer) review and, if published, were less well cited than papers whose titles did not include specific names. Papers with intermediate length titles were more successful during editorial review, although the effect was small and title word count was not predictive of citations. No features of titles were predictive of reviewer willingness to review papers or the length of time a paper was in peer review. We conclude that titles have changed in structure over time, but features of title structure have only small or no relationship with success during editorial review and post-publication impact. The title feature that was most predictive of manuscript success: papers whose titles emphasize broader conceptual or comparative issues fare better both pre- and post-publication than do papers with organism-specific titles.

Are there age-related differences in social suggestibility to central and peripheral misinformation?

BACKGROUND/STUDY CONTEXT: Dalton and Daneman ( 2006 , Memory, 14, 486-501) showed that young adults can be induced to accept misinformation from a co-witness, even if it contradicts central features of a previously witnessed event. This study investigated whether older adults are also susceptible to social suggestion, and if so, whether to the same or different degree as their younger counterparts. The study also investigated whether participants were more likely to succumb to suggestions delivered by a peer or an older figure. Younger and older adults viewed an action video in the presence of a younger or older confederate co-witness. During a postevent discussion, the confederate introduced misinformation about central and peripheral features of the co-witnessed event. Finally, participants responded to true-false statements about the event and rated how confident they were in their decisions. Older adults were able to correctly reject false statements about an event that had been mentioned during the discussion by the confederate less often than they were able to correctly reject false statements that had not been mentioned, even if the misstatements contradicted central features of the previously witnessed event. However, older adults were no more susceptible to a co-witness's misleading suggestions than were their younger counterparts, and the age of the confederate did not influence the size of the suggestibility effect for younger or older adults. When baseline memory accuracy (correct rejection rates for unmentioned false information) is controlled, older adults are no more susceptible to misleading suggestions from a co-witness than are their younger counterparts. Age of the confederate did not influence the size of the suggestibility effect and thus provided no support for the predictions that participants are more likely to succumb to misleading suggestions delivered by a peer or by an older authority figure.

Monitoring social threat is essential for maintaining healthy social relationships, and recent studies suggest a neural alarm system that governs our response to social rejection. Frontal-midline theta (4-8 Hz) oscillatory power might act as a neural correlate of this system by being sensitive to unexpected social rejection. Here, we examined whether frontal-midline theta is modulated by individual differences in personality constructs sensitive to social disconnection. In addition, we examined the sensitivity of feedback-related brain potentials (i.e., the feedback-related negativity and P3) to social feedback. Sixty-five undergraduate female participants (mean age = 19.69 years) participated in the Social Judgment Paradigm, a fictitious peer-evaluation task in which participants provided expectancies about being liked/disliked by peer strangers. Thereafter, they received feedback signaling social acceptance/rejection. A community structure analysis was employed to delineate personality profiles in our data. Results provided evidence of two subgroups: one group scored high on attachment-related anxiety and fear of negative evaluation, whereas the other group scored high on attachment-related avoidance and low on fear of negative evaluation. In both groups, unexpected rejection feedback yielded a significant increase in theta power. The feedback-related negativity was sensitive to unexpected feedback, regardless of valence, and was largest for unexpected rejection feedback. The feedback-related P3 was significantly enhanced in response to expected social acceptance feedback. Together, these findings confirm the sensitivity of frontal midline theta oscillations to the processing of social threat, and suggest that this alleged neural alarm system behaves similarly in individuals that differ in personality constructs relevant to social evaluation.

Adolescent girls are involved in physical dating violence as both perpetrators and victims, and there are negative consequences associated with each of these behaviors. This article used a prospective design with 519 girls dating in grade 9 to predict profiles of dating violence in grade 11 based on relationships with families of origin (child maltreatment experiences, harsh parenting), and peers (harassment, delinquency, relational aggression). In addition, dating violence profiles were compared on numerous indices of adjustment (school connectedness, grades, self-efficacy and community connectedness) and maladjustment (suicide attempts, distress, delinquency, sexual behavior) for descriptive purposes. The most common profile was no dating violence (n = 367) followed by mutual violence (n = 81). Smaller numbers of girls reported victimization or perpetration only (ns = 39 and 32, respectively). Predicting grade 11 dating violence profile membership from grade 9 relationships was limited, although delinquency, parental rejection, and sexual harassment perpetration predicted membership to the mutually violent group, and delinquency predicted the perpetrator-only group. Compared to the non-violent group, the mutually violent girls in grade 11 had lower grades, poorer self-efficacy, and lower school connectedness and community involvement. Furthermore, they had higher rates of peer aggression and delinquency, were less likely to use condoms and were much more likely to have considered suicide. There were fewer differences among the profiles for girls involved with dating violence. In addition, the victims-only group reported higher rates of sexual intercourse, comparable to the mutually violent group and those involved in nonviolent relationships. Implications for prevention and intervention are highlighted.

Peer victimization among children and adolescents is a major public health concern, given its widespread individual and societal ramifications. Victims of peer aggression often face significant levels of psychological distress and social difficulties, such as depression, suicidal ideation, suicide attempts, and social rejection. The purpose of the present study was to examine whether cognitive distortions and perceptions of social support moderate the association between peer victimization and suicidal thoughts among psychiatrically hospitalized adolescents. Participants included 183 psychiatrically hospitalized adolescents (ages 13–18). In multiple regression analyses that controlled for gender, social and cognitive factors served as significant resources factors. Cognitive factors also moderated the relationship between peer victimization and suicidal ideation. PMID:25125940

Early Adolescent Depressive Symptoms: Prediction from Clique Isolation, Loneliness, and Perceived Social Acceptance

Witvliet, Miranda; Brendgen, Mara; van Lier, Pol A. C.; Vitaro, Frank

2010-01-01

This study examined whether clique isolation predicted an increase in depressive symptoms and whether this association was mediated by loneliness and perceived social acceptance in 310 children followed from age 11–14 years. Clique isolation was identified through social network analysis, whereas depressive symptoms, loneliness, and perceived social acceptance were assessed using self ratings. While accounting for initial levels of depressive symptoms, peer rejection, and friendlessness at age 11 years, a high probability of being isolated from cliques from age 11 to 13 years predicted depressive symptoms at age 14 years. The link between clique isolation and depressive symptoms was mediated by loneliness, but not by perceived social acceptance. No sex differences were found in the associations between clique isolation and depressive symptoms. These results suggest that clique isolation is a social risk factor for the escalation of depressive symptoms in early adolescence. Implications for research and prevention are discussed.

Cejas, Claudia

2017-06-01

The objective of this study was to evaluate metrics related to manuscripts rejected by AJR with and without review during 2014 and to determine their final disposition: no record of eventual publication, eventually published, published with modified authors and title, published with the same title but modified authors, and published with modified title but the same authors. A total of 1245 unsolicited manuscripts submitted from January to December 2014 were included in this retrospective analysis. Data were extracted from the AJR's manuscript submission system. Standard statistical analysis was used to assess the fate of a sample of 200 rejected manuscripts. Of the 200 manuscripts studied, 117 (59%) were published in other scientific journals (61 with revision, 56 without revision; Χ 2 = 0.329, p = 0.566). Thirty-two of the 61 manuscripts (52%) rejected after peer review were later published in other journals without changes in their titles or authors, 16 (26%) with changes only in authors, 10 (16%) with changes only in their titles, and three (5%) with changes in authors and titles. Twenty-six of the 56 manuscripts (46%) rejected without peer review were published without changes in their titles or authors, 17 (30%) with changes in authors, 11 (20%) with changes only in their titles, and two (4%) with changes in both authors and titles (p = 0.686). Ten articles were published in open access journals. Of the remaining articles, those that had been reviewed were published in journals with a mean impact factor ± SD of 2.37 ± 1.30, and those that had not been reviewed were published in journals with a mean impact factor of 2.04 ± 1.06. Analysis of the 25th and 75th percentiles revealed that values were also higher for the group rejected with review (Wilcoxon rank sum test: W = 1679, p = 0.1127). Out of 61 articles rejected for publication with review, 52.5% were published with changes to their abstracts, whereas the remaining 47.5% were unchanged. This analysis found that manuscripts submitted to AJR that were rejected after review were published in journals with higher impact factors than those rejected without review. The commentaries provided by AJR reviewers and section editors appear to improve the quality of rejected manuscripts and thus contribute to the scientific community.

Social distance and behavioral attributes of developmentally handicapped and normal children.

PubMed

Sherman, L W; Burgess, D E

1985-12-01

20 behavioral attributes predicting social distance were examined among 101 junior high school students in six classrooms. The sample included 8 developmentally handicapped students, of whom at least one of each was mainstreamed into each classroom. Subjects were predominantly white, middle-class, suburban midwesterners. A sociometric nomination measure was used to obtain behavioral attribute profiles of the students which were then used to predict a psychometric measure of social distance. Handicapped students were not more socially distant than their normal peers. Factor analysis of the 20 behavioral attributes yielded four factors, three of which were significant predictors of classroom social distance, accounting for better than half the variance in social distance. These were described as Incompetent/Unassertive, Positive/Active/Assertive, and Passive/Unassertive. Social rejection in mainstreamed classrooms is more a function of perceived behavioral attributes than the label developmentally handicapped.

Do MZ twins have discordant experiences of friendship? A qualitative hypothesis-generating MZ twin differences study

PubMed Central

Moran, Nicola; Plomin, Robert

2017-01-01

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

Unlike adults, children and adolescents show predominantly increased neural activation to social exclusion by members of the opposite gender

2016-01-01

The effects of group membership on brain responses to social exclusion have been investigated in adults, revealing greater anterior cingulate responses to exclusion by members of one’s in-group (e.g. same-gender). However, social exclusion is a critical aspect of peer relations in youth and reaches heightened salience during adolescence, a time when social anxiety disorders are also emergent. While the behavioral and neural correlates of social exclusion in adolescence have been extensively explored, the effects of group membership on peer rejection are less clear. The current study used functional magnetic resonance imaging (fMRI) to investigate the differential neural correlates of being excluded by peers of one’s same-versus opposite-gender during an online ball-toss game. Participants were a group of typically developing children and adolescents (7–17 years). As predicted, anterior cingulate cortex showed a main effect of social exclusion versus fair play. However, unlike a previous adult study, this region did not show increased activation to same-gender exclusion. Instead, several regions differentiating same-versus opposite-gender exclusion were exclusively more sensitive to exclusion by one’s opposite gender. These results are discussed in the context of adolescent socioemotional development. PMID:26592311

Regulating the interpersonal self: strategic self-regulation for coping with rejection sensitivity.

People high in rejection sensitivity (RS) anxiously expect rejection and are at risk for interpersonal and personal distress. Two studies examined the role of self-regulation through strategic attention deployment in moderating the link between RS and maladaptive outcomes. Self-regulation was assessed by the delay of gratification (DG) paradigm in childhood. In Study 1, preschoolers from the Stanford University community who participated in the DG paradigm were assessed 20 years later. Study 2 assessed low-income, minority middle school children on comparable measures. DG ability buffered high-RS people from interpersonal difficulties (aggression, peer rejection) and diminished well-being (e.g., low self-worth, higher drug use). The protective effect of DG ability on high-RS children's self-worth is explained by reduced interpersonal problems. Attentional mechanisms underlying the interaction between RS and strategic self-regulation are discussed.

Peer Rejection and Perceived Quality of Relations With Schoolmates Among Children With ADHD.

2018-06-01

The main aim of the current study was to investigate the links between ADHD diagnosis and the objective and subjective dimensions of social relationships among children from primary schools. We used the data from 36 regular classrooms, consisting of 718 students, with each containing at least one child with an established clinical diagnosis of ADHD (38 children). For children with ADHD, the level of the perceived quality of social relations was lower than that of children without such a diagnosis. After controlling for sociometric status, the impact of ADHD on perceived status proved to be statistically nonsignificant but the indirect impact of ADHD on this status through sociometric status was statistically significant. Children diagnosed with ADHD are more often rejected by their peers and have a more pessimistic view of their social world. Moreover, ADHD diagnosis does not have a direct influence on the perceived quality of social relations otherwise than through sociometric status.

Duration and quality of the peer review process: the author's perspective.

PubMed

Huisman, Janine; Smits, Jeroen

2017-01-01

To gain insight into the duration and quality of the scientific peer review process, we analyzed data from 3500 review experiences submitted by authors to the SciRev.sc website. Aspects studied are duration of the first review round, total review duration, immediate rejection time, the number, quality, and difficulty of referee reports, the time it takes authors to revise and resubmit their manuscript, and overall quality of the experience. We find clear differences in these aspects between scientific fields, with Medicine, Public health, and Natural sciences showing the shortest durations and Mathematics and Computer sciences, Social sciences, Economics and Business, and Humanities the longest. One-third of journals take more than 2 weeks for an immediate (desk) rejection and one sixth even more than 4 weeks. This suggests that besides the time reviewers take, inefficient editorial processes also play an important role. As might be expected, shorter peer review processes and those of accepted papers are rated more positively by authors. More surprising is that peer review processes in the fields linked to long processes are rated highest and those in the fields linked to short processes lowest. Hence authors' satisfaction is apparently influenced by their expectations regarding what is common in their field. Qualitative information provided by the authors indicates that editors can enhance author satisfaction by taking an independent position vis-à-vis reviewers and by communicating well with authors.

Sociodynamic relationships between children who stutter and their non-stuttering classmates

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

Who helps whom? Investigating the development of adolescent prosocial relationships.

2016-06-01

We investigated adolescent prosocial relations by examining social networks based on the question "Who helps you (e.g., with homework, with repairing a flat [bicycle] tire, or when you are feeling down?)." The effects of individual characteristics (academic achievement, symptoms of depressive mood, and peer status) on receiving help and giving help were examined, and we investigated the contribution of (dis)similarity between adolescents to the development of prosocial relations. Gender, structural network characteristics, and friendship relations were taken into account. Data were derived from the Social Network Analysis of Risk behavior in Early adolescence (SNARE) study, and contained information on students in 40 secondary school classes across 3 waves (N = 840, M age = 13.4, 49.7% boys). Results from longitudinal social network analyses (RSiena) revealed tendencies toward reciprocation of help and exchange of help within helping groups. Furthermore, boys were less often mentioned as helpers, particularly by girls. Depressed adolescents were less often mentioned as helpers, especially by low-depressed peers. Moreover, lower academic achievers indicated that they received help from their higher achieving peers. Rejected adolescents received help more often, but they less often helped low-rejected peers. Last, low- and high-popular adolescents less often helped each other, and also high-popular adolescents less often helped each other. These findings show that (dis)similarity in these characteristics is an important driving factor underlying the emergence and development of prosocial relations in the peer context, and that prosocial behavior should be defined in terms of benefitting particular others.

Multi-Stage Open Peer Review: Scientific Evaluation Integrating the Strengths of Traditional Peer Review with the Virtues of Transparency and Self-Regulation

PubMed Central

Pöschl, Ulrich

2012-01-01

The traditional forms of scientific publishing and peer review do not live up to all demands of efficient communication and quality assurance in today’s highly diverse and rapidly evolving world of science. They need to be advanced and complemented by interactive and transparent forms of review, publication, and discussion that are open to the scientific community and to the public. The advantages of open access, public peer review, and interactive discussion can be efficiently and flexibly combined with the strengths of traditional scientific peer review. Since 2001 the benefits and viability of this approach are clearly demonstrated by the highly successful interactive open access journal Atmospheric Chemistry and Physics (ACP, www.atmos-chem-phys.net) and a growing number of sister journals launched and operated by the European Geosciences Union (EGU, www.egu.eu) and the open access publisher Copernicus (www.copernicus.org). The interactive open access journals are practicing an integrative multi-stage process of publication and peer review combined with interactive public discussion, which effectively resolves the dilemma between rapid scientific exchange and thorough quality assurance. Key features and achievements of this approach are: top quality and impact, efficient self-regulation and low rejection rates, high attractivity and rapid growth, low costs, and financial sustainability. In fact, ACP and the EGU interactive open access sister journals are by most if not all standards more successful than comparable scientific journals with traditional or alternative forms of peer review (editorial statistics, publication statistics, citation statistics, economic costs, and sustainability). The high efficiency and predictive validity of multi-stage open peer review have been confirmed in a series of dedicated studies by evaluation experts from the social sciences, and the same or similar concepts have recently also been adopted in other disciplines, including the life sciences and economics. Multi-stage open peer review can be flexibly adjusted to the needs and peculiarities of different scientific communities. Due to the flexibility and compatibility with traditional structures of scientific publishing and peer review, the multi-stage open peer review concept enables efficient evolution in scientific communication and quality assurance. It has the potential for swift replacement of hidden peer review as the standard of scientific quality assurance, and it provides a basis for open evaluation in science. PMID:22783183

Peer Contagion in Child and Adolescent Social and Emotional Development

PubMed Central

Dishion, Thomas J.; Tipsord, Jessica M.

2012-01-01

In this article, we examine the construct of peer contagion in childhood and adolescence and review studies of child and adolescent development that have identified peer contagion influences. Evidence suggests that children's interactions with peers are tied to increases in aggression in early and middle childhood and amplification of problem behaviors such as drug use, delinquency, and violence in early to late adolescence. Deviancy training is one mechanism that accounts for peer contagion effects on problem behaviors from age 5 through adolescence. In addition, we discuss peer contagion relevant to depression in adolescence, and corumination as an interactive process that may account for these effects. Social network analyses suggest that peer contagion underlies the influence of friendship on obesity, unhealthy body images, and expectations. Literature is reviewed that suggests how peer contagion effects can undermine the goals of public education from elementary school through college and impair the goals of juvenile corrections systems. In particular, programs that “select” adolescents at risk for aggregated preventive interventions are particularly vulnerable to peer contagion effects. It appears that a history of peer rejection is a vulnerability factor for influence by peers, and adult monitoring, supervision, positive parenting, structure, and self-regulation serve as protective factors.

Salvy, Sarah-Jeanne; Bowker, Julie C.

2015-01-01

Obesity during childhood and adolescence is a growing problem in the United States, Canada, and around the world that leads to significant physical, psychological, and social impairment. In recent years, empirical research on factors that contribute to the development and maintenance of obesity has begun to consider peer experiences, such as peer rejection, peer victimization, and friendship. Peer experiences have been theoretically and empirically related to the “Big Two” contributors to the obesity epidemic, eating and physical activity, but there has not been a comprehensive review of the extant empirical literature. In this article, we review and synthesize the emerging theoretical and empirical literatures on peer experiences in relation to: (a) eating (food consumption and food selection); and (b) physical activity, during childhood and adolescence. A number of limitations and issues in the theoretical and empirical literatures are also discussed, along with future research directions. In conclusion, we argue that the involvement of children and adolescents’ peer networks in prevention and intervention efforts may be critical for promoting and maintaining positive behavioral health trajectories.

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

Paying To Belong: When Does Rejection Trigger Ingratiation?

PubMed Central

Romero-Canyas, Rainer; Downey, Geraldine; Reddy, Kavita S.; Rodriguez, Sylvia; Cavanaugh, Timothy J.; Pelayo, Rosemary

2010-01-01

Societies and social scientists have long held the belief that exclusion induces ingratiation and conformity, an idea in contradiction with robust empirical evidence linking rejection with hostility and aggression. The classic literatures on ingratiation and conformity help resolve this contradiction by identifying circumstances under which rejection may trigger efforts to ingratiate. Jointly, findings from these literatures suggest that when people are given an opportunity to impress their rejecters, ingratiation is likely after rejection experiences that are harsh and that occur in important situations that threaten the individual’s self-definition. Four studies tested the hypothesis that people high in rejection sensitivity, and therefore dispositionally concerned about rejection, will utilize opportunities to ingratiate after harsh rejection in situations that are self-defining. In three studies of situations that are particularly self-defining for men, rejection predicted ingratiation among men (but not women) who were high in rejection sensitivity. In a fourth study, harsh rejection in a situation particularly self-defining for women predicted ingratiation among highly rejection-sensitive women (but not men). These findings help identify the specific circumstances under which people are willing to act in socially desirable ways toward those who have rejected them harshly. PMID:20649367

Individual differences in neural responses to social rejection: the joint effect of self-esteem and attentional control

Individuals with low self-esteem have been found to react more negatively to signs of interpersonal rejection than those with high self-esteem. However, previous research has found that individual differences in attentional control can attenuate negative reactions to social rejection among vulnerable, low self-esteem individuals. The current fMRI study sought to elucidate the neurobiological substrate of this buffering effect. We hypothesized and found that while looking at scenes of social rejection (vs negative scenes) low self-esteem high attentional control individuals engaged the rostral anterior cingulate cortex (rACC), an area of the brain associated with emotional control, more than their low self-esteem low attentional control peers. Furthermore, we found that low self-esteem high attentional control individuals evaluated social rejection as less arousing and less rejecting in a separate behavioral task. Importantly, activation in the rACC fully mediated the relationship between the interaction of self-esteem and attentional control and emotional evaluations, suggesting that the rACC activation underlies the buffering effects of attentional control. Results are discussed in terms of individual differences in emotional vulnerability and protection and by highlighting the role of rACC in emotion regulation. PMID:21609969

The role of conspiracist ideation and worldviews in predicting rejection of science.

PubMed

Lewandowsky, Stephan; Gignac, Gilles E; Oberauer, Klaus

2013-01-01

Among American Conservatives, but not Liberals, trust in science has been declining since the 1970's. Climate science has become particularly polarized, with Conservatives being more likely than Liberals to reject the notion that greenhouse gas emissions are warming the globe. Conversely, opposition to genetically-modified (GM) foods and vaccinations is often ascribed to the political Left although reliable data are lacking. There are also growing indications that rejection of science is suffused by conspiracist ideation, that is the general tendency to endorse conspiracy theories including the specific beliefs that inconvenient scientific findings constitute a "hoax." We conducted a propensity weighted internet-panel survey of the U.S. population and show that conservatism and free-market worldview strongly predict rejection of climate science, in contrast to their weaker and opposing effects on acceptance of vaccinations. The two worldview variables do not predict opposition to GM. Conspiracist ideation, by contrast, predicts rejection of all three scientific propositions, albeit to greatly varying extents. Greater endorsement of a diverse set of conspiracy theories predicts opposition to GM foods, vaccinations, and climate science. Free-market worldviews are an important predictor of the rejection of scientific findings that have potential regulatory implications, such as climate science, but not necessarily of other scientific issues. Conspiracist ideation, by contrast, is associated with the rejection of all scientific propositions tested. We highlight the manifold cognitive reasons why conspiracist ideation would stand in opposition to the scientific method. The involvement of conspiracist ideation in the rejection of science has implications for science communicators.

Greater endorsement of a diverse set of conspiracy theories predicts opposition to GM foods, vaccinations, and climate science. Conclusions Free-market worldviews are an important predictor of the rejection of scientific findings that have potential regulatory implications, such as climate science, but not necessarily of other scientific issues. Conspiracist ideation, by contrast, is associated with the rejection of all scientific propositions tested. We highlight the manifold cognitive reasons why conspiracist ideation would stand in opposition to the scientific method. The involvement of conspiracist ideation in the rejection of science has implications for science communicators. PMID:24098391

2011-06-01

The aim was to identify risk indicators from preadolescence (age period 10-12) that significantly predict unfavorable deviations from normal anxiety development throughout adolescence (age period 10-17 years). Anxiety symptoms were assessed in a community sample of 2,220 boys and girls at three time-points across a 5-year interval. Risk indicators were measured at baseline and include indicators from the child, family, and peer domain. Associations with anxiety were measured with multilevel growth curve analyses. A stable difference in anxiety over adolescence was found between high and low levels of a range of child factors (frustration, effortful control), family factors (emotional warmth received from parents, lifetime parental internalizing problems), and peer factor (victims of bullying) (P <.001). In contrast, the difference in anxiety between high and low levels of factors, such as self-competence, unfavorable parenting styles, and bully victims, decreased over adolescence (P <.001). For other family factors, associations were weaker (.05

The impact of countervailing social network influences (i.e., pro-social, anti-social or HIV risk peers) on problem behaviors (i.e., HIV drug risk, HIV sex risk or anti-social behaviors) among 696 homeless youth was assessed using structural equation modeling. Results revealed that older youth were less likely to report having pro-social peers and were more likely to have HIV risk and anti-social peers. A longer time homeless predicted fewer pro-social peers, more anti-social peers, and more HIV risk peers. Heterosexual youth reported fewer HIV risk peers and more pro-social peers. Youth recruited at agencies were more likely to report pro-social peers. Having pro-social peers predicted less HIV sex risk behavior and less anti-social behavior. Having HIV risk peers predicted all problem behavior outcomes. Anti-social peers predicted more anti-social behavior. Once the association between anti-social and HIV risk peers was accounted for independently, having anti-social peers did not independently predict sex or drug risk behaviors.

Emotion Knowledge, Loneliness, Negative Social Experiences, and Internalizing Symptoms Among Low-Income Preschoolers

2014-01-01

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

Combating the sting of rejection with the pleasure of revenge: A new look at how emotion shapes aggression.

PubMed

Chester, David S; DeWall, C Nathan

2017-03-01

How does emotion explain the relationship between social rejection and aggression? Rejection reliably damages mood, leaving individuals motivated to repair their negatively valenced affective state. Retaliatory aggression is often a pleasant experience. Rejected individuals may then harness revenge's associated positive affect to repair their mood. Across 6 studies (total N = 1,516), we tested the prediction that the rejection-aggression link is motivated by expected and actual mood repair. Further, we predicted that this mood repair would occur through the positive affect of retaliatory aggression. Supporting these predictions, naturally occurring (Studies 1 and 2) and experimentally manipulated (Studies 3 and 4) motives to repair mood via aggression moderated the rejection-aggression link. These effects were mediated by sadistic impulses toward finding aggression pleasant (Studies 2 and 4). Suggesting the occurrence of actual mood repair, rejected participants' affective states were equivalent to their accepted counterparts after an act of aggression (Studies 5 and 6). This mood repair occurred through a dynamic interplay between preaggression affect and aggression itself, and was driven by increases in positive affect (Studies 5 and 6). Together, these findings suggest that the rejection-aggression link is driven, in part, by the desire to return to affective homeostasis. Additionally, these findings implicate aggression's rewarding nature as an incentive for rejected individuals' violent tendencies. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Self-esteem Modulates Medial Prefrontal Cortical Responses to Evaluative Social Feedback

PubMed Central

Kelley, William M.; Heatherton, Todd F.

2010-01-01

Self-esteem is a facet of personality that influences perception of social standing and modulates the salience of social acceptance and rejection. As such, self-esteem may bias neural responses to positive and negative social feedback across individuals. During functional magnetic resonance imaging scanning, participants (n = 42) engaged in a social evaluation task whereby they ostensibly received feedback from peers indicating they were liked or disliked. Results demonstrated that individuals with low self-esteem believed that they received less positive feedback from others and showed enhanced activity to positive versus negative social feedback in the ventral anterior cingulate cortex/medial prefrontal cortex (vACC/mPFC). By contrast, vACC/mPFC activity was insensitive to positive versus negative feedback in individuals with high self-esteem, and these individuals consistently overestimated the amount of positive feedback received from peers. Voxelwise analyses supported these findings; lower self-esteem predicted a linear increase in vACC/mPFC response to positive versus negative social feedback. Taken together, the present findings propose a functional role for the vACC/mPFC in representing the salience of social feedback and shaping perceptions of relative social standing. PMID:20351022

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

Long-Term Associations of Justice Sensitivity, Rejection Sensitivity, and Depressive Symptoms in Children and Adolescents

PubMed Central

Bondü, Rebecca; Sahyazici-Knaak, Fidan; Esser, Günter

2017-01-01

Depressive symptoms have been related to anxious rejection sensitivity, but little is known about relations with angry rejection sensitivity and justice sensitivity. We measured rejection sensitivity, justice sensitivity, and depressive symptoms in 1,665 9-to-21-year olds at two points of measurement. Participants with high T1 levels of depressive symptoms reported higher anxious and angry rejection sensitivity and higher justice sensitivity than controls at T1 and T2. T1 rejection, but not justice sensitivity predicted T2 depressive symptoms; high victim justice sensitivity, however, added to the stabilization of depressive symptoms. T1 depressive symptoms positively predicted T2 anxious and angry rejection and victim justice sensitivity. Hence, sensitivity toward negative social cues may be cause and consequence of depressive symptoms and requires consideration in cognitive-behavioral treatment of depression. PMID:28955257

Lack of clear identification of patients at high risk of acute rejection hampers the ability to individualize immunosuppressive therapy. Here we studied whether thymic function may predict acute rejection in antithymocyte globulin (ATG)-treated renal transplant recipients in 482 patients prospectively studied during the first year post-transplant of which 86 patients experienced acute rejection. Only CD45RA(+)CD31(+)CD4(+) T cell (recent thymic emigrant [RTE]) frequency (RTE%) was marginally associated with acute rejection in the whole population. This T-cell subset accounts for 26% of CD4(+) T cells. Pretransplant RTE% was significantly associated with acute rejection in ATG-treated patients (hazard ratio, 1.04; 95% confidence interval, 1.01-1.08) for each increased percent in RTE/CD4(+) T cells), but not in anti-CD25 monoclonal (αCD25 mAb)-treated patients. Acute rejection was significantly more frequent in ATG-treated patients with high pretransplant RTE% (31.2% vs. 16.4%) or absolute number of RTE/mm(3) (31.7 vs. 16.1). This difference was not found in αCD25 monclonal antibody-treated patients. Highest values of both RTE% (>31%, hazard ratio, 2.50; 95% confidence interval, 1.09-5.74) and RTE/mm(3) (>200/mm(3), hazard ratio, 3.71; 95% confidence interval, 1.59-8.70) were predictive of acute rejection in ATG-treated patients but not in patients having received αCD25 monoclonal antibody). Results were confirmed in a retrospective cohort using T-cell receptor excision circle levels as a marker of thymic function. Thus, pretransplant thymic function predicts acute rejection in ATG-treated patients. Copyright © 2016 International Society of Nephrology. Published by Elsevier Inc. All rights reserved.

Prefrontal Recruitment During Social Rejection Predicts Greater Subsequent Self-Regulatory Imbalance and Impairment: Neural and Longitudinal Evidence

PubMed Central

Chester, David S.; DeWall, C. Nathan

2014-01-01

Social rejection impairs self-regulation, yet the neural mechanisms underlying this relationship remain unknown. The right ventrolateral prefrontal cortex (rVLPFC) facilitates self-regulation and plays a robust role in regulating the distress of social rejection. However, recruiting this region’s inhibitory function during social rejection may come at a self-regulatory cost. As supported by prominent theories of self-regulation, we hypothesized that greater rVLPFC recruitment during rejection would predict a subsequent self-regulatory imbalance that favored reflexive impulses (i.e., cravings), which would then impair self-regulation. Supporting our hypotheses, rVLPFC activation during social rejection was associated with greater subsequent nucleus accumbens (NAcc) activation and lesser functional connectivity between the NAcc and rVLPFC to appetitive cues. Over seven days, the effect of daily felt rejection on daily self-regulatory impairment was exacerbated among participants who showed a stronger rVLPFC response to social rejection. This interactive effect was mirrored in the effect of daily felt rejection on heightened daily alcohol cravings. Our findings suggest that social rejection likely impairs self-regulation by recruiting the rVLPFC, which then tips the regulatory balance towards reward-based impulses. PMID:25094019

Freeman, Laura MacMullen; Locke, Jill; Rotheram-Fuller, Erin; Mandell, David

2017-06-01

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.

Previous reports revealed the potential value of the soluble CD30 level (sCD30) as biomarker for the risk of acute rejection and graft failure after renal transplantation, here we examined its use for the prediction of safe tapering of calcineurin inhibitors as well as late acute rejection. In a cohort of renal transplant patients receiving triple immunosuppressive therapy we examined whether sCD30 can be used as a marker for safe (rejection-free) discontinuation of tacrolimus at six months after transplantation (TDS cohort: 24 rejectors and 44 non-rejecting controls). Also, in a second cohort of patients (n=22, rejectors n=11 and non-rejectors n=11), participating in a clinical trial of rituximab as induction therapy after renal transplantation (RITS cohort), we examined whether sCD30 could predict the occurrence of late (>3months post-transplant) acute rejection episodes. sCD30 was measured by ELISA in serum taken before and at several time points after transplantation. Overall, in the TDS cohort sCD30 decreased after transplantation. No difference in sCD30 was observed between rejectors and non-rejecting controls at any of the time points measured. In addition, in the RITS cohort, sCD30 measured at three months after transplantation were not indicative for the occurrence of late acute rejection. In two prospectively followed cohorts of renal transplant patients we found no association between sCD30 and the occurrence of either late acute rejection or acute rejection after reduction of immunosuppression.

The interpersonal model of loss of control (LOC) eating proposes that socially distressing situations lead to anxious states that trigger excessive food consumption. Self-reports support these links, but the neurobiological underpinnings of these relationships remain unclear. We therefore examined brain regions associated with anxiety in relation to LOC eating and energy intake in the laboratory. Twenty-two overweight and obese (BMIz: 1.9±0.4) adolescent (15.8±1.6y) girls with LOC eating (LOC+, n=10) and without LOC eating (LOC−, n=12) underwent functional magnetic resonance imaging (fMRI) during a simulated peer interaction chatroom paradigm. Immediately after the fMRI scan, girls consumed lunch ad libitum from a 10,934-kcal laboratory buffet meal with the instruction to “let yourself go and eat as much as you want.” Pre-specified hypotheses regarding activation of five regions of interest were tested. Analysis of fMRI data revealed a significant group by peer feedback interaction in the ventromedial prefrontal cortex (vmPFC), such that LOC+ had less activity following peer rejection (vs. acceptance), while LOC− had increased activity (p <.005). Moreover, functional coupling between vmPFC and striatum for peer rejection (vs. acceptance) interacted with LOC status: coupling was positive for LOC+, but negative in LOC− (p <.005). Activity of fusiform face area (FFA) during negative peer feedback from high-value peers also interacted with LOC status (p < .005). A positive association between FFA activation and intake during the meal was observed among only those with LOC eating. In conclusion, overweight and obese girls with LOC eating may be distinguished by a failure to engage regions of prefrontal cortex implicated in emotion regulation in response to social distress. The relationship between FFA activation and food intake supports the notion that heightened sensitivity to incoming interpersonal cues and perturbations in socio-emotional neural circuits may lead to overeating in order to cope with negative affect elicited by social discomfort in susceptible youth.

Neural Correlates of Social Influence on Risk Taking and Substance Use in Adolescents.

PubMed

Telzer, Eva H; Rogers, Christina R; Van Hoorn, Jorien

2017-09-01

Adolescents often engage in elevated levels of risk taking that gives rise to substance use. Family and peers constitute the primary contextual risk factors for adolescent substance use. This report reviews how families and peers influence adolescent neurocognitive development to inform their risk taking and subsequent substance use. Developmental neuroscience using functional magnetic resonance imaging (fMRI) has identified regions of the brain involved in social cognition, cognitive control, and reward processing that are integrally linked to social influence on adolescent risk taking. These neural mechanisms play a role in how peer and family influence (e.g., physical presence, relationship quality, rejection) translates into adolescent substance use. Peers and families can independently, and in tandem, contribute to adolescent substance use, for better or for worse. We propose that future work utilize fMRI to investigate the neural mechanisms involved in different aspects of peer and family influence, and how these contexts uniquely and interactively influence adolescent substance use initiation and escalation across development.

Interparental Conflict, Parenting Behavior, and Children's Friendship Quality as Correlates of Peer Aggression and Peer Victimization Among Aggressor/Victim Subgroups in South Korea.

The focus of this study was to examine whether interparental conflict, maternal parenting behaviors, and children's friendship quality varied as a function of peer aggression/victim subgroups among a sample of 227 elementary school children and their mothers in South Korea. Both self-report and peer-report data indicated that the majority of the students were uninvolved in peer aggression situations, and the number of participants in the subgroups (aggressors, victims, and aggressor-victims) varied depending on the source of report. According to the self-report data, victims and aggressor-victims reported a higher level of maternal rejection than uninvolved youth. Aggressors, victims, and aggressor-victims reported higher maternal neglect than uninvolved youth. The highest level of interparental conflict was reported by victims, followed by aggressors. Interestingly, no significant differences were found in positive functioning of friendship quality among the subgroups, although results indicated a significant difference among groups in negative friendship quality. © The Author(s) 2013.

Status Differences in Target-Specific Prosocial Behavior and Aggression.

PubMed

Closson, Leanna M; Hymel, Shelley

2016-09-01

Previous studies exploring the link between social status and behavior have predominantly utilized measures that do not provide information regarding toward whom aggression or prosocial behavior is directed. Using a contextualized target-specific approach, this study examined whether high- and low-status adolescents behave differently toward peers of varying levels of status. Participants, aged 11-15 (N = 426, 53 % females), completed measures assessing aggression and prosocial behavior toward each same-sex grademate. A distinct pattern of findings emerged regarding the likeability, popularity, and dominance status of adolescents and their peer targets. Popular adolescents reported more direct aggression, indirect aggression, and prosocial behavior toward popular peers than did unpopular adolescents. Well-accepted adolescents reported more prosocial behavior toward a wider variety of peers than did rejected adolescents. Finally, compared to subordinate adolescents, dominant adolescents reported greater direct and indirect aggression toward dominant than subordinate peers. The results highlight the importance of studying target-specific behavior to better understand the status-behavior link.

Peer referencing in adolescent decision making as a function of perceived parenting style.

PubMed

Bednar, Dell Elaine; Fisher, Terri D

2003-01-01

This study examined the relationship between parenting style and adolescent decision making. Two hundred sixty-two college students completed a decision-making scale as well as a parenting scale in an effort to determine if the child-rearing style of their parents was related to the tendency of these late adolescents to reference peers rather than parents or other adults in decision making. The results indicated that adolescents raised by authoritative parents tended to refer to their parents for moral and informational decisions, while adolescents raised by authoritarian, permissive, or neglecting-rejecting parents more often referenced their peers for moral and informational decisions. Adolescents referred to their peers for social decisions regardless of how they were raised. Parental responsiveness was a significant factor in determining the source of adolescent decision-making assistance, but parental demandingness was not. It was concluded that less orientation toward peers during late adolescence seems to be another advantage of authoritative parenting.

The current study investigated the association between Machiavellianism and children's peer interactions in the playground using observational methods. Primary school children (N = 34; 17 female), aged 9 to 11 years, completed the Kiddie Mach scale and were observed in natural play during 39 recesses (average observed time = 11.70 hours) over a full school year. Correlations for boys revealed that Machiavellianism was related to more time engaging in direct and indirect aggression, being accepted into other peer groups, and accepting peers into their own social group. Correlations revealed that for girls, Machiavellianism was associated with lower levels of indirect aggression, less time being accepted into other groups and less time accepting and rejecting other children into their own group. This preliminary pilot study indicates that Machiavellianism is associated with children's observed social behaviour and aims to promote future observational research in this area.

The aim of this study was to test the hypothesis that echocardiographic strain imaging, by tracking subtle alterations in myocardial function, and cardiac magnetic resonance T1 mapping, by quantifying tissue properties, are useful and complement each other to detect acute cellular rejection in heart transplant recipients. Noninvasive alternatives to endomyocardial biopsy are highly desirable to monitor acute cellular rejection. Surveillance endomyocardial biopsies, catheterizations, and echocardiograms performed serially according to institutional protocol since transplantation were retrospectively reviewed. Sixteen-segment global longitudinal strain (GLS) and circumferential strain were measured before, during, and after the first rejection and at 2 time points for patients without rejection using Velocity Vector Imaging for the first part of the study. The second part, with cardiac magnetic resonance added to the protocol, served to validate previously derived strain cutoffs, examine the progression of strain over time, and to determine the accuracy of strain and T1 measurements to define acute cellular rejection. All tests were performed within 48 h. Median time to first rejection (16 grade 1 rejection, 15 grade ≥2 rejection) was 3 months (interquartile range: 3 to 36 months) in 49 patients. GLS and global circumferential strain worsened significantly during grade 1 rejection and ≥2 rejection and were independent predictors of any rejection. In the second part of the study, T1 time ≥1,090 ms, extracellular volume ≥32%, GLS >-14%, and global circumferential strain ≥-24% had 100% sensitivity and 100% negative predictive value to define grade ≥2 rejection with 70%, 63%, 55%, and 35% positive predictive values, respectively. The combination of GLS >-16% and T1 time ≥1,060 ms defined grade 1 rejection with 91% sensitivity and 92% negative predictive value. After successful treatment, T1 times decreased significantly. T1 mapping and echocardiographic GLS can serve to guide endomyocardial biopsy selectively. Copyright © 2018 American College of Cardiology Foundation. Published by Elsevier Inc. All rights reserved.

Parent emotion socialization and pre-adolescent's social and emotional adjustment: Moderating effects of autonomic nervous system reactivity.

PubMed

McQuade, Julia D; Breaux, Rosanna P

2017-12-01

This study examined whether measures of children's autonomic nervous system (ANS) reactivity to social stress moderated the effect of parent emotion socialization on children's social and emotional adjustment. Sixty-one children (9-13 years) completed a peer rejection task while their respiratory sinus arrhythmia reactivity (RSA-R) and skin conductance level reactivity (SCL-R) were assessed. Parents' report of supportive and non-supportive reactions to their child's negative emotions served as measures of emotion socialization. Measures of children's social and emotional adjustment included: teacher-rated peer rejection, aggression, and prosocial behavior and parent-rated aggressive/dysregulated behavior and emotion regulation skills. Measures of children's ANS reactivity moderated the effect of parent emotion socialization on children's adjustment. Supportive responses were more protective for children evidencing RSA augmentation whereas non-supportive responses were more detrimental for children evidencing low SCL-R. Thus children's ANS reactivity during social stress may represent a biological vulnerability that influences sensitivity to parent emotion socialization. Copyright © 2017 Elsevier B.V.

Blodorn, Alison; Major, Brenda; Hunger, Jeffrey; Miller, Carol

2015-01-01

The present research tested the hypothesis that the negative effects of weight stigma among higher body-weight individuals are mediated by expectations of social rejection. Women and men who varied in objective body-weight (body mass index; BMI) gave a speech describing why they would make a good date. Half believed that a potential dating partner would see a videotape of their speech (weight seen) and half believed that a potential dating partner would listen to an audiotape of their speech (weight unseen). Among women, but not men, higher body-weight predicted increased expectations of social rejection, decreased executive control resources, decreased self-esteem, increased self-conscious emotions and behavioral displays of self-consciousness when weight was seen but not when weight was unseen. As predicted, higher body-weight women reported increased expectations of social rejection when weight was seen (versus unseen), which in turn predicted decreased self-esteem, increased self-conscious emotions, and increased stress. In contrast, lower body-weight women reported decreased expectations of social rejection when weight was seen (versus unseen), which in turn predicted increased self-esteem, decreased self-conscious emotions, and decreased stress. Men’s responses were largely unaffected by body-weight or visibility, suggesting that a dating context may not be identity threatening for higher body-weight men. Overall, the present research illuminates a rejection-expectation pathway by which weight stigma undermines higher body-weight women’s health. PMID:26752792

Multivariate prediction of upper limb prosthesis acceptance or rejection.

Biddiss, Elaine A; Chau, Tom T

2008-07-01

To develop a model for prediction of upper limb prosthesis use or rejection. A questionnaire exploring factors in prosthesis acceptance was distributed internationally to individuals with upper limb absence through community-based support groups and rehabilitation hospitals. A total of 191 participants (59 prosthesis rejecters and 132 prosthesis wearers) were included in this study. A logistic regression model, a C5.0 decision tree, and a radial basis function neural network were developed and compared in terms of sensitivity (prediction of prosthesis rejecters), specificity (prediction of prosthesis wearers), and overall cross-validation accuracy. The logistic regression and neural network provided comparable overall accuracies of approximately 84 +/- 3%, specificity of 93%, and sensitivity of 61%. Fitting time-frame emerged as the predominant predictor. Individuals fitted within two years of birth (congenital) or six months of amputation (acquired) were 16 times more likely to continue prosthesis use. To increase rates of prosthesis acceptance, clinical directives should focus on timely, client-centred fitting strategies and the development of improved prostheses and healthcare for individuals with high-level or bilateral limb absence. Multivariate analyses are useful in determining the relative importance of the many factors involved in prosthesis acceptance and rejection.

Previous research has often highlighted hyperactivity in emotion regions to simple, static social threat cues in social anxiety disorder (SAD). Investigation of the neurobiology of SAD using more naturalistic paradigms can further reveal underlying mechanisms and how these relate to clinical outcomes. We used fMRI to investigate responses to novel dynamic rejection stimuli in individuals with SAD (N=70) and healthy controls (HC; N=17), and whether these responses predicted treatment outcomes following cognitive behavioral therapy (CBT) or acceptance and commitment therapy (ACT). Both HC and SAD groups reported greater distress to rejection compared to neutral social stimuli. At the neural level, HCs exhibited greater activations in social pain/rejection regions, including dorsal anterior cingulate cortex and anterior insula, to rejection stimuli. The SAD group evidenced a different pattern, with no differences in these rejection regions and relatively greater activations in the amygdala and other regions to neutral stimuli. Greater responses in anterior cingulate cortex and the amygdala to rejection vs. neutral stimuli predicted better CBT outcomes. In contrast, enhanced activity in sensory-focused posterior insula predicted ACT responses. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

2013-05-01

Although nearly all domain experts agree that carbon dioxide emissions are altering the world's climate, segments of the public remain unconvinced by the scientific evidence. Internet blogs have become a platform for denial of climate change, and bloggers have taken a prominent role in questioning climate science. We report a survey of climate-blog visitors to identify the variables underlying acceptance and rejection of climate science. Our findings parallel those of previous work and show that endorsement of free-market economics predicted rejection of climate science. Endorsement of free markets also predicted the rejection of other established scientific findings, such as the facts that HIV causes AIDS and that smoking causes lung cancer. We additionally show that, above and beyond endorsement of free markets, endorsement of a cluster of conspiracy theories (e.g., that the Federal Bureau of Investigation killed Martin Luther King, Jr.) predicted rejection of climate science as well as other scientific findings. Our results provide empirical support for previous suggestions that conspiratorial thinking contributes to the rejection of science. Acceptance of science, by contrast, was strongly associated with the perception of a consensus among scientists.

CONTEXT Considerable research has examined reciprocal relationships between parenting, peers and adolescent problem behavior; however, such studies have largely considered the influence of peers and parents separately. It is important to examine simultaneously the relationships between parental monitoring, peer risk involvement and adolescent sexual risk behavior, and whether increases in peer risk involvement and changes in parental monitoring longitudinally predict adolescent sexual risk behavior. METHODS Four waves of sexual behavior data were collected between 2008/2009 and 2011 from high school students aged 13–17 in the Bahamas. Structural equation and latent growth curve modeling were used to examine reciprocal relationships between parental monitoring, perceived peer risk involvement and adolescent sexual risk behavior. RESULTS For both male and female youth, greater perceived peer risk involvement predicted higher sexual risk behavior index scores, and greater parental monitoring predicted lower scores. Reciprocal relationships were found between parental monitoring and sexual risk behavior for males and between perceived peer risk involvement and sexual risk behavior for females. For males, greater sexual risk behavior predicted lower parental monitoring; for females, greater sexual risk behavior predicted higher perceived peer risk involvement. According to latent growth curve models, a higher initial level of parental monitoring predicted decreases in sexual risk behavior, whereas both a higher initial level and a higher growth rate of peer risk involvement predicted increases in sexual risk behavior. CONCLUSION Results highlight the important influence of peer risk involvement on youths’ sexual behavior and gender differences in reciprocal relationships between parental monitoring, peer influence and adolescent sexual risk behavior.

The immunologic status of kidney allograft recipients affects transplant outcome. High levels of pretransplant serum soluble CD30 correlate with an increased risk of acute rejection. Studies show conflicting results. We evaluated the relation between pretransplant serum sCD30 levels with the risk of posttransplant acute kidney rejection in renal transplant recipients. This prospective cohort study was performed between March 2010 and March 2011 on 77 kidney transplant recipients (53 men [68.8%], 24 women [31.2%]; mean age, 41 ± 14 y). Serum samples were collected 24 hours before transplant and analyzed for soluble CD30 levels by enzyme-linked immunosorbent assay. Patients were followed for 6 months after transplant. Acute biopsy-proven rejection episodes were recorded, serum creatinine levels were measured, and glomerular filtration rates were calculated at the first and sixth months after transplant. Preoperative serum soluble CD30 levels were compared in patients with and without rejection. The mean pretransplant serum soluble CD30 level was 92.1 ± 47.3 ng/mL. At 6 months' follow-up, 10 patients experienced acute rejection. Mean pretransplant soluble CD30 levels were 128.5 ± 84 ng/mL versus 86.7 ± 37 ng/mL in patients with and without acute rejection episodes (P = .008). At 100 ng/mL, the sensitivity, specificity, and positive and negative predictive values of pretransplant serum soluble CD30 level to predict acute rejection were 70%, 73.6%, 29.1%, and 94.3%. We showed a significant relation between pretransplant serum soluble CD30 levels and acute allograft rejection. High pretransplant levels of serum soluble CD30 can be a risk factor for kidney transplant rejection, and its high negative predictive value at various cutoffs make it useful to find candidates with a low risk of acute rejection after transplant.

Mean girls: sex differences in the effects of mild traumatic brain injury on the social dynamics of juvenile rat play behaviour.

Mychasiuk, R; Hehar, H; Farran, A; Esser, M J

2014-02-01

Clinical studies indicate that children who experience a traumatic brain injury (TBI) are often the victim of peer rejection, have very few mutual friends, and are at risk for long-term behavioural and social impairments. Owing to the fact that peer play is critical for healthy development, it is possible that the long-term impairments are associated not only with the TBI, but also altered play during this critical period of brain development. This study was designed to determine if social dynamics and juvenile play are altered in rats that experience a mild TBI (mTBI) early in life. Play-fighting behaviours were recorded and analyzed for young male and female Sprague Dawley rats that were given either an mTBI or a sham injury. The study found that the presence of an mTBI altered the play fighting relationship, and the nature of the alterations were dependent upon the sex of the pairing and the injury status of their peers. Sham rats were significantly less likely to initiate play with an mTBI rat, and were more likely to respond to a play initiation from an mTBI rat with an avoidant strategy. This effect was significantly more pronounced in female rats, whereby it appeared that female rats with an mTBI were particularly rejected and most often excluded from play experiences. Male rats with an mTBI learned normal play strategies from their sham peers (when housed in mixed cages), whereas female rats with an mTBI show heightened impairment in these conditions. Play therapy may need to be incorporated into treatment strategies for children with TBI. Copyright © 2013 Elsevier B.V. All rights reserved.

The Consensus Project: Survey of the peer-reviewed scientific literature to determine the degree of consensus on anthropogenic climate change

Prior studies have identified a consensus amongst climate science experts regarding anthropogenic global warming (AGW) as outlined by the Intergovernmental Panel on Climate Change (Oreskes 2004). Despite this evidence, a poll of 1010 American adults (Leiserowitz et al. 2011) revealed that only 15% believed that a large majority (>81%) of climate scientists think that global warming is caused mostly by human activities. This lack of public awareness of the consensus has hindered the implementation of climate policy, in the United States in particular. Using an online abstract classification and rating system in combination with an email survey of the papers' authors, a team of 24 contributors to the weblog Skeptical Science undertook an analysis of 12,465 abstracts published between 1991 and 2011, listed in the Web of Science with the keywords "global warming" and/or "global climate change". Each abstract was reviewed independently at least twice, based on the abstract and the title, with no reference to the authorship. This study represents the single largest survey of peer-reviewed climate research, and the large sample size allows for identification of patterns in climate research over time. Abstracts were classified based on subject focus, using a set of written criteria, as one of "impacts", "methods", "mitigation", "paleoclimate", or "opinion"; and rated according to degree of endorsement or rejection of AGW: three categories each of explicit/implicit endorsement and rejection, and a neutral category. Abstracts that referred to a changing climate but did not assert or reject a linkage to human-produced greenhouse gases were rated "neutral", and this rating proved to be by far the most common, comprising approximately 67% of total abstracts. Endorsement categories made up approximately 33% of all abstracts examined, whereas those rejecting AGW comprised less than 1%. Overall, endorsements outnumbered rejections approximately 50-to-1, consistent with the 97-98% AGW consensus found in previous studies (Doran and Zimmerman 2009 and Anderegg et al. 2010). 2011 had the most total papers surveyed at 1,683. An average of 3.7 rejections per year were identified, with a maximum of 9 in 2011. Endorsements averaged 187 per year, with a maximum of 521 in 2011. These results represent the most comprehensive confirmation of the AGW consensus to date.

Do academically-engaged adolescents experience social sanctions from the peer group?

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.

Bi-directional Effects of Peer Relationships and Adolescent Substance Use: A Longitudinal Study.

McDonough, Meghan H; Jose, Paul E; Stuart, Jaimee

2016-08-01

Understanding the predictors of the onset and maintenance of substance use in adolescence is important because it is a recognized health risk. The present longitudinal study examined whether negative peer influence and peer connectedness predicted changes in adolescent alcohol, cigarette, marijuana, and other illegal drug use, and reciprocally whether substance use predicted changes in peer relationships. Adolescents (N = 1940; 52 % female; 52 % European New Zealanders, 30 % Maori, 12 % Pacific Islander) aged 10-15 years completed measures annually for 3 years. Cross-lagged panel models were used to examine bi-directional effects. Negative peer influence predicted increased use of all substances. In turn, alcohol, cigarette, and marijuana use predicted increased negative peer influence, but this effect was inconsistent over time. Peer connectedness, predicted to diminish the frequency of substance use, was found to be unrelated to it. Breaking the reciprocal cycle between peer coercion and substance use would seem to be useful for reducing substance use.

2017-12-01

Intestinal failure characterized by inadequate maintenance of nutrition via normal intestinal function comprises a group of disorders with many different causes. If parenteral nutrition dependency develops, which is associated with higher mortality and complications, it is considered for intestine transplantation. However, the graft failure rate is not low, and acute cellular rejection is one of the most important reasons for graft failure. As a result, early identification of rejection and timely modification of anti-rejection medications have been considered to be associated with better graft and patient survival rates. The diagnostic gold standard for rejection is mainly based on histology, but hours of delay by pathology may occur. Some researchers investigated the association of endoscopic images with graft rejection to provide timely diagnosis. In this study, we present the first case report with characteristic features under magnifying endoscopy with a narrow-band imaging system to predict epithelial regeneration and improvement of graft rejection in a patient with small-bowel transplantation.

A Relational Model of Sexual Minority Mental and Physical Health: The Negative Effects of Shame on Relationships, Loneliness, and Health

PubMed Central

Mereish, Ethan H.; Poteat, V. Paul

2015-01-01

Sexual minorities (e.g., lesbians, gay men, bisexual individuals) are at higher risk for mental and physical health disparities than heterosexuals, and some of these disparities relate to minority stressors such as discrimination. Yet, there is little research elucidating pathways that predict health or that promote resiliency among sexual minorities. Building on the minority stress model, the present study utilized relational cultural theory to situate sexual minority health within a relational framework. Specifically, the study tested mediators of the relationships between distal (i.e., discrimination, rejection, victimization) and proximal stressors (i.e., internalized homophobia, sexual orientation concealment) and psychological and physical distress for sexual minorities. Among 719 sexual minority adults, structural equation modeling analyses were used to test four models reflecting the mediating effects of shame, poorer relationships with a close peer and the LGBT community, and loneliness on the associations between minority stressors and psychological distress (i.e., depression and anxiety) and physical distress (i.e., distressing physical symptoms). As hypothesized, the associations between distal and proximal minority stressors and distress were mediated by shame, poorer relationships with a close peer and the LGBT community, and loneliness. Findings underscore the possible relational and interpersonal mechanisms by which sexual minority stressors lead to psychological and physical distress. PMID:26010289

Evaluation of annual, global seismicity forecasts, including ensemble models

Taroni, Matteo; Zechar, Jeremy; Marzocchi, Warner

2013-04-01

In 2009, the Collaboratory for the Study of the Earthquake Predictability (CSEP) initiated a prototype global earthquake forecast experiment. Three models participated in this experiment for 2009, 2010 and 2011—each model forecast the number of earthquakes above magnitude 6 in 1x1 degree cells that span the globe. Here we use likelihood-based metrics to evaluate the consistency of the forecasts with the observed seismicity. We compare model performance with statistical tests and a new method based on the peer-to-peer gambling score. The results of the comparisons are used to build ensemble models that are a weighted combination of the individual models. Notably, in these experiments the ensemble model always performs significantly better than the single best-performing model. Our results indicate the following: i) time-varying forecasts, if not updated after each major shock, may not provide significant advantages with respect to time-invariant models in 1-year forecast experiments; ii) the spatial distribution seems to be the most important feature to characterize the different forecasting performances of the models; iii) the interpretation of consistency tests may be misleading because some good models may be rejected while trivial models may pass consistency tests; iv) a proper ensemble modeling seems to be a valuable procedure to get the best performing model for practical purposes.

Pre-transplant immune state defined by serum markers and alloreactivity predicts acute rejection after living donor kidney transplantation.

Acute rejection (AR) remains a major cause for long-term kidney allograft failure. Reliable immunological parameters suitable to define the pre-transplant immune state and hence the individual risk of graft rejection are highly desired to preferably adapt the immunosuppressive regimen in advance. Donor and third party alloreactivities were determined by mixed lymphocyte cultures. Soluble forms of CD25, CD30, and CD44 were detected in patients' serum by ELISA. Various lymphocyte subpopulations were measured using flow cytometry. All patients received triple immunosuppression (tacrolimus/mycophenolate mofetil/steroids) and were grouped according to biopsy results within the first year: rejection-free (RF, n = 13), borderline (BL, n = 5), or acute rejection (AR, n = 7). Patients with AR showed the highest pre-transplant alloreactivities and serum levels (sCD25/sCD30/sCD44) according to the pattern RF < BL < AR. Relying on serum analysis only, multivariate logistic regression (logit link function) yielded a prognostic score for prediction of rejection with 75.0% sensitivity and 69.2% specificity. Patients with rejection showed markedly higher pre-transplant frequencies of CD4(+) /CD8(+) T cells lacking CD28, but lower numbers of CD8(+) CD161(bright) T cells and NK cells than RF individuals. Pre-transplant immune state defined by alloreactivity, serum markers, and particular lymphocyte subsets seems to correlate with occurrence of graft rejection after kidney transplantation. A prognostic score based on pre-transplant serum levels has shown great potential for prediction of rejection episodes and should be further evaluated. © 2014 John Wiley & Sons A/S.

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.

Adolescents take on different social roles mediated by gender, which affect the development of their identity and the expression of school violence. The purpose of this work is to study the behavioral differences in bullying depending on gender. The sample (N=641) is aged between 12 and 16 years old. Personal variables are assessed by self-reports, and relational variables by sociometric measures. Results indicate a large incidence of bullying, peer rejection, and school maladjustment among boys. Girls report more relational aggressions, acceptance and social skills, but also higher personal maladjustment. Female victims are rejected the most. Gender differences seem more relevant in relational variables, suggesting the special importance of the relational context in bullying.

In 2011, Nephrology Dialysis and Transplantation (NDT) established a more restrictive selection process for manuscripts submitted to the journal, reducing the acceptance rate from 25% (2008-2009) to currently about 12-15%. To achieve this goal, we decided to score the priority of manuscripts submitted to NDT and to reject more papers at triage than in the past. This new scoring system allows a rapid decision for the authors without external review. However, the risk of such a restrictive policy may be that the journal might fail to capture important studies that are eventually published in higher-ranked journals. To look into this problem, we analysed random samples of papers (∼10%) rejected by NDT in 2012. Of the papers rejected at triage and those rejected after regular peer review, 59 and 61%, respectively, were accepted in other journals. A detailed analysis of these papers showed that only 4 out of 104 and 7 out of 93 of the triaged and rejected papers, respectively, were published in journals with an impact factor higher than that of NDT. Furthermore, for all these papers, independent assessors confirmed the evaluation made by the original reviewers. The number of citations of these papers was similar to that typically obtained by publications in the corresponding journals. Even though the analyses seem reassuring, previous observations made by leading journals warn that the risk of 'big misses', resulting from selective editorial policies, remains a real possibility. We will therefore continue to maintain a high degree of alertness and will periodically track the history of manuscripts rejected by NDT, particularly papers that are rejected at triage by our journal. © The Author 2015.

Early diagnosis of acute rejection and effective immunosuppressive therapy lead to improvement in graft survival following kidney transplantation. In this study, we aimed to establish a urinary protein profile suitable to distinguish between patients with rejection and stable graft function and to predict acute rejection based on postoperatively collected urine samples. A further objective was to identify candidate proteins for the use as biomarkers in clinical practice. Urine samples of 116 kidney recipients were included. Rejection was proven by biopsy (n = 58), and stable transplant function was monitored for at least 2 years (n = 58). Postoperative urine samples were collected between 3rd and 10th day following transplantation. Urinary protein profiles were obtained by surface-enhanced laser desorption/ionization time-of-flight mass spectrometry. Protein identification and validation were performed using multiplex fluorescence 2DE, peptide mass fingerprinting and enzyme-linked immunosorbent assay. A protein profile including four mass peaks differentiated acute rejection from stable transplants at the time point of rejection and at the postoperative state with 73 % sensitivity and 88 % specificity. Alpha-1-microglobulin (A1MG) and Haptoglobin (Hp) were identified as putative rejection biomarkers. Protein levels were significantly higher in postoperative urine from patients with rejection (A1MG 29.13 vs. 22.06 μg/ml, p = 0.001; Hp 628.34 vs. 248.57 ng/ml, p = 0.003). The combination of both proteins enabled the diagnosis of early rejection with 85 % sensitivity and 80 % specificity. Protein profiling using mass spectrometry is suitable for noninvasive detection of rejection-specific changes following kidney transplantation. A specific protein profile enables the prediction of early acute allograft rejection in the immediate postoperative period. A1MG and Hp appear to be reliable rejection biomarkers.

Moral judgments about Jewish-Arab intergroup exclusion: The role of cultural identity and contact

Prejudice and discrimination as justifications for social exclusion are often viewed as violations of the moral principles of welfare, justice, and equality but intergroup exclusion can also often be viewed as a necessary and legitimate means to maintain group identity and cohesion (Rutland, Killen, & Abrams, 2010). The current study was guided by the Social Reasoning Developmental perspective (Killen & Rutland, 2011) to examine the moral judgments of social exclusion encounters, and the degree to which cultural identity and actual contact with members of other cultural groups is related to social evaluations. Surprisingly, no research has examined how intergroup contact bears on moral judgments about Jewish-Arab encounters in the U.S. The present study surveyed 241 Jewish and 249 non-Arab/non-Jewish (comparison group) 14 and 17 year olds to assess their cultural identification, intergroup contact, and moral judgments regarding intergroup peer social exclusion situations between Jewish and Arab youth in peer, home, and community contexts. Participants overwhelmingly rejected exclusion of an outgroup member explicitly because of their group membership, though male and Jewish participants were more accepting of such exclusion and less accepting of including an outgroup member. Context effects emerged, and exclusion was rated as most acceptable in the community context and least acceptable in the peer context. Three factors of identity (i.e., exploration, commitment, and concern for relationships) were explored. Generally, higher identity commitment and lower identity concern for relationships were related to more inclusive evaluations. Interactions between the identity factors and intergroup contact and cultural group, however, differentially predicted evaluations of intergroup exclusion. PMID:24188040

In February 2013, Biochemia Medica has joined CrossRef, which enabled us to implement CrossCheck plagiarism detection service. Therefore, all manuscript submitted to Biochemia Medica are now first assigned to Research integrity editor (RIE), before sending the manuscript for peer-review. RIE submits the text to CrossCheck analysis and is responsible for reviewing the results of the text similarity analysis. Based on the CrossCheck analysis results, RIE subsequently provides a recommendation to the Editor-in-chief (EIC) on whether the manuscript should be forwarded to peer-review, corrected for suspected parts prior to peer-review or immediately rejected. Final decision on the manuscript is, however, with the EIC. We hope that our new policy and manuscript processing algorithm will help us to further increase the overall quality of our Journal.

2013-01-01

We examined three interrelated questions: (1) Who selects physically aggressive friends?; (2) Are physically aggressive adolescents influential?; and (3) Who is susceptible to influence from these friends? Using stochastic actor-based modeling, we tested our hypotheses using a sample of 480 adolescents (ages 11–13) who were followed across four assessments (fall and spring of 6th and 7th grade). After controlling for other factors that drive network and behavioral dynamics, we found that physically aggressive adolescents were attractive as friends, physically aggressive adolescents and girls were more likely to select physically aggressive friends, and peer-rejected adolescents were less likely to select physically aggressive friends. There was an overall peer influence effect, but gender and social status were not significant moderators of influence. PMID:24068860

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

Peer interactions and executive function play central roles in the development of healthy children, as peer problems have been indicative of lower cognitive competencies such as self-regulatory behavior and poor executive function has been indicative of problem behaviors and social dysfunction. However, few studies have focused on the relation between peer interactions and executive function and the underlying mechanisms that may create this link. Using a national sample (n = 1164, 48.6% female) from the Study of Early Child Care and Youth Development (SECCYD), we analyzed executive function and peer problems (including victimization and rejection) across three waves within each domain (executive function or peer problems), beginning in early childhood and ending in middle adolescence. Executive function was measured as a multi-method, multi-informant composite including reports from parents on the Children's Behavior Questionnaire and Child Behavior Checklist and child's performance on behavioral tasks including the Continuous Performance Task, Woodcock-Johnson, Tower of Hanoi, Operation Span Task, Stroop, and Tower of London. Peer problems were measured as a multi-informant composite including self, teacher, and afterschool caregiver reports on multiple peer-relationship scales. Using a cross-lagged design, our Structural Equation Modeling findings suggested that experiencing peer problems contributed to lower executive function later in childhood and better executive function reduced the likelihood of experiencing peer problems later in childhood and middle adolescence, although these relations weakened as a child moves into adolescence. The results highlight that peer relationships are involved in the development of strengths and deficits in executive function and vice versa.

Purpose To examine how cerebral palsy (CP) and sociometric status at age 10 explain the development of a cognitive bias across two groups of adolescents aged 15. Method Children with CP (N = 60) and without CP (N = 57) are part of a follow-up study. Three categories of sociometric status (popular, average, rejected) were obtained by conducting a class-wide interview in the class of the target children at age 10. At 15 years old, the same children (CP and non-CP) were asked to complete the Home Interview With Child questionnaire measuring a cognitive bias (hostile attribution of intentions (AI)). Results Children with CP, especially girls, were significantly more rejected and less popular than controls at age 10. At age 15, among all participants, sociometric rejected and popular children tended to have a higher percentage of hostile AI than sociometric average children. Conclusions There were no significant results for the combined effect of CP and sociometric status on the development of hostile AI at age 15. However, knowing the risk incurred by children with CP of being socially rejected, attention should be paid in the rehabilitation process to opportunities for social participation to facilitate the development of social competence. Implications for Rehabilitation Level I or II cerebral palsy (CP) is a condition that affects not only motor abilities but also social competence in children. Sociometric status in a group tends to affect the development of the ability to interprete intentions of others during adolescence. Sociometric measures in the class of children with CP could be a useful tool in the rehabilitation process in order to better define social participation opportunities. To improve social participation attempts, rehabilitation interventions should target social initiating skills, flexibility in interpreting peers' behaviours, and ability to react effectively to negative peer treatment.

Across species, kin bond together to promote survival. We sought to understand the dyadic effect of exclusion by kin (as opposed to non-kin strangers) on brain activity of the mother and her child and their subjective distress. To this end, we probed mother-child relationships with a computerized ball-toss game Cyberball. When excluded by one another, rather than by a stranger, both mothers and children exhibited a significantly pronounced frontal P2. Moreover, upon kin-rejection versus stranger-rejection, both mothers and children showed incremented left frontal positive slow waves for rejection events. Children reported more distress upon exclusion than their own mothers. Similar to past work, relatively augmented negative frontal slow wave activity predicted greater self-reported ostracism distress. This effect, generalized to the P2, was limited to mother or child- rejection by kin, with comparable magnitude of effect across kin identity (mothers vs. children). For both mothers and children, the frontal P2 peak was significantly pronounced for kin-rejection versus stranger rejection. Taken together, our results document the rapid categorization of social signals as kin-relevant and the specificity of early and late neural markers for predicting felt ostracism. PMID:24909389

MODIFIED REVERSE OSMOSIS SYSTEM FOR TREATMENT OF PRODUCED WATERS

T.M. Whitworth; Liangxiong Li

2002-09-15

This report describes work performed during the second year of the project ''Modified reverse osmosis system for treatment of produced waters.'' We performed two series of reverse osmosis experiments using very thin bentonite clay membranes compacted to differing degrees. The first series of 10 experiments used NaCl solutions with membranes that ranged between 0.041 and 0.064mm in thickness. Our results showed compaction of such ultra-thin clay membranes to be problematic. The thickness of the membranes was exceeded by the dimensional variation in the machined experimental cell and this is believed to have resulted in local bypassing of the membrane withmore » a resultant decrease in solute rejection efficiency. In two of the experiments, permeate flow was varied as a percentage of the total flow to investigate results of changing permeate flow on solute rejection. In one experiment, the permeate flow was varied between 2.4 and 10.3% of the total flow with no change in solute rejection. In another experiment, the permeate flow was varied between 24.6 and 52.5% of the total flow. In this experiment, the solute rejection rate decreased as the permeate occupied greater fractions of the total flow. This suggests a maximum solute rejection efficiency for these clay membranes for a permeate flow of between 10.3 and 24.6% of the total; flow. Solute rejection was found to decrease with increasing salt concentration and ranged between 62.9% and 19.7% for chloride and between 61.5 and 16.8% for sodium. Due to problems with the compaction procedure and potential membrane bypassing, these rejection rates are probably not the upper limit for NaCl rejection by bentonite membranes. The second series of four reverse osmosis experiments was conducted with a 0.057mm-thick bentonite membrane and dilutions of a produced water sample with an original TDS of 196,250 mg/l obtained from a facility near Loco Hill, New Mexico, operated by an independent. These experiments tested the separation efficiency of the bentonite membrane for each of the dilutions. We found that membrane efficiency decreased with increasing solute concentration and with increasing TDS. The rejection of SO{sub 4}{sup 2-} was greater than Cl{sup -}. This may be because the SO{sub 4}{sup 2-} concentration was much lower than the Cl{sup -} concentration in the waters tested. The cation rejection sequence varied with solute concentration and TDS. The solute rejection sequence for multi-component solutions is difficult to predict for synthetic membranes; it may not be simple for clay membranes either. The permeate flows in our experiments were 4.1 to 5.4% of the total flow. This suggests that very thin clay membranes may be useful for some separations. Work on development of a spiral-wound clay membrane module found that it is difficult to maintain compaction of the membrane if the membrane is rolled and then inserted in the outer tube. A different design was tried using a cylindrical clay membrane and this also proved difficult to assemble with adequate membrane compaction. The next step is to form the membrane in place using hydraulic pressure on a thin slurry of clay in either water or a nonpolar organic solvent such as ethanol. Technology transfer efforts included four manuscripts submitted to peer-reviewed journals, two abstracts, and chairing a session on clays as membranes at the Clay Minerals Society annual meeting.« less

Borderline Personality Disorder Symptoms and Aggression: A Within-Person Process Model

2017-01-01

Theoretical and empirical work suggests that aggression in those with borderline personality disorder (BPD) occurs primarily in the context of emotional reactivity, especially anger and shame, in response to perceived rejection. Using intensive repeated measures, we examined a within-person process model in which perceived rejection predicts increases in aggressive urges and behaviors via increases in negative affect (indirect effect) and in which BPD symptoms exacerbate this process (moderated mediation). Participants were 117 emerging adult women (ages 18–24) with recent histories of aggressive behavior who were recruited from a community-based longitudinal study of at-risk youth. Personality disorder symptoms were assessed by semi-structured clinical interview, and aggressive urges, threats, and behaviors were measured in daily life during a three-week ecological momentary assessment (EMA) protocol. Multilevel path models revealed that within-person increases in perceived rejection predicted increases in negative affect, especially in women with greater BPD symptoms. In turn, increases in negative affect predicted increased likelihood of aggressive urges or behaviors. Further analysis revealed that BPD symptoms predicted greater anger and shame reactivity to perceived rejection, but not to criticism or insult. Additionally, only anger was associated with increases in aggression after controlling for other negative emotions. Whereas BPD symptoms exacerbated the link between perceived rejection and aggression via increases in negative affect (particularly anger), this process was attenuated in women with greater antisocial personality disorder (ASPD) symptoms. These findings suggest that anger reactivity to perceived rejection is one unique pathway, distinct from ASPD, by which BPD symptoms increase risk for aggression. PMID:28383936

Defend or repair? Explaining responses to in-group moral failure by disentangling feelings of shame, rejection, and inferiority.

2012-05-01

Research on shame about in-group moral failure has yielded paradoxical results. In some studies, shame predicts self-defensive motivations to withdraw. In other studies, shame predicts pro-social motivations, such as restitution. We think that this paradox can be explained by disentangling the numerous appraisals and feelings subsumed under the label "shame." In 2 studies, we asked community samples of Norwegians about their in-group's discrimination against the Tater minority. Confirmatory factor analysis validated the measures of the appraisals and feelings used in Study 1 (N = 206) and Study 2 (N = 173). In both studies, an appraisal of the in-group as suffering a moral defect best predicted felt shame, whereas an appraisal of concern for condemnation of the in-group best predicted felt rejection. In both studies, felt rejection best predicted self-defensive motivation, whereas felt shame best predicted pro-social motivation. Implications for conceptualizing and studying shame are discussed.

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.

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.

This study examined cross-lagged associations between positive teacher and peer relations and academic skill development. Reading and math skills were tested among 625 students in kindergarten and Grade 4. Teacher reports of positive affect toward each student and classmate reports of peer acceptance were gathered in Grades 1-3. The results showed, first, that positive teacher affect toward the student and peer acceptance were reciprocally associated: Positive teacher affect predicted higher peer acceptance, and higher peer acceptance predicted a higher level of positive teacher affect. Second, the effect of positive teacher affect on academic skill development was partly mediated via peer acceptance, while the effect of early academic skills on peer acceptance was partly mediated via positive teacher affect. The results suggest that a warm and supportive teacher can increase a student's peer acceptance, which, in turn, is positively associated with learning outcomes. (c) 2015 APA, all rights reserved).

Should intellectual property be disseminated by "forwarding" rejected letters without permission?

PubMed

Gupta, V K

1996-08-01

Substantive scientific letter writing is a cost-effective mode of complementing observational and experimental research. The value of such philosophically uncommitted and unsponsored well-balanced scientific activity has been relegated. Critical letter writing entails the abilities to: maintain rational scepticism; refuse to conform in order to explain data; persist in keeping common sense centre-stage; exercise logic to evaluate the biological significance of mathematical figures, including statistics, and the ability to sustain the will to share insights regarding disease mechanisms on an ostensibly lower research platform. During peer review, innovative letter writing may share the occasionally unfortunate fate of innovative research. Rejected scientific letters do not automatically lose copyright. Periodicals with high letter loads will see some valuable contributions wasted, but that is the price for maintaining autonomy in scientific publication. The scientific community is an integrated whole that must respect the rights of authors at all levels. Unauthorised forwarding of rejected letters sets the dangerous precedent of justifying unjust means.

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.

Farji-Brener and Kitzberger (2014; hereafter FBK) resurrect the issues of Farji-Brener (2007) concerning manuscripts that are submitted to journals but that are not sent out for peer review: a process we call “reject following editorial review” (RFER). We thank FBK for reviving discussion about this important topic as new challenges, including new publication outlets, peer-review models, and an increasingly complex and voluminous scientific literature, are emerging across the publication landscape. While we disagree with FBK's perspective and conclusions, we recognize that this discussion can help to improve editorial and publication processes, and we welcome the opportunity to inform the ecological community about the current status of editorial practice at ESA journals.

Understanding maladaptive responses to rejection: Aggression with an audience.

DeBono, Amber; Layton, Rebekah L; Freeman, Nicholas; Muraven, Mark

Logically, responding aggressively to rejection is maladaptive because one is unlikely to seek a relationship with an aggressor. We predict that when concealed, the illogical aggressive response to rejection is more likely, whereas when the rejected individuals' aggressive responses are perceived as public, the aggressive acts may be reduced. Participants were rejected by others (Experiment 1) or were either accepted or rejected during an online ball-tossing game (Experiment 2) and were then given an opportunity to aggress publicly or privately. Across experiments, when the opportunity to aggress was made public, rejected participants exhibited less aggressive behavior. When concerned about the perception of their public aggressive responses by others, rejected individuals' aggressive responses diminished compared with those whose actions were private. Crucially, this extended to aggression visible only to neutral others, suggesting that effects cannot solely be due to fear of retribution.

[Sequential monitoring of renal transplant with aspiration cytology].

To evaluate the utility of kidney aspiration cytology in the sequential monitorization of acute rejection in renal transplant patients. Thirty patients were submitted to 376 aspirations. The clinical diagnoses were independently established. The representativity of the samples reached 82.7%. The total corrected increment index and the number of immunoactivated cells were higher during acute rejection as compared to normal allograft function, acute tubular necrosis, and cyclosporine nephrotoxicity. The parameters to the diagnosis of acute rejection were sensitivity: 71.8%, specificity: 87.3%, positive predictive value: 50.9%, negative predictive value: 94.9% and accuracy 84.9%. The false positive results were mainly related to cytomegalovirus infection or to the administration of OKT3. In 10 out of 11 false negative results incipient immunoactivation was present alerting to the possibility of acute rejection. Kidney aspiration cytology is a useful tool for the sequential monitorization of acute rejection in renal transplant patients. The best results are reached when the results of aspiration cytology are analyzed with the clinical data.

Soluble CD30 for the prediction and detection of kidney transplant rejection.

Although safer and more effective immunosuppressants as well as enhanced immunosuppressive protocols are continuously being developed in order to increase graft survival, they come at the steep price of drug-related complications and important side effects. In addition, the value of panel reactive antibodies determination, which at present is the single most used indicator of an increased risk of transplant rejection, is now being reevaluated. Therefore, effective tailoring of immunosuppressive therapy minimizing the above-mentioned pitfalls requires the existence of dependable biomarkers that adequately monitor rejection risk both before and after transplantation. Here we review the data yielded by studies assessing the usefulness of measuring soluble CD30 levels (sCD30) in kidney transplant rejection. These data collectively show that sCD30 serum content has a considerable predictive/diagnostic value for acute rejection of renal grafts, particularly when measured a few days after transplantation.

The mediating role of perceived peer support in the relation between quality of attachment and internalizing problems in adolescence: a longitudinal perspective.

PubMed

Pace, Ugo; Zappulla, Carla; Di Maggio, Rosanna

2016-10-01

The study was aimed to verify, from a longitudinal perspective, whether perceived peer support would mediate the relationship between attachment and internalizing problems. Longitudinal participants included 482 adolescents (245 boys) aged 14-15 years in Wave 1 and 17-18 years in Wave 2. Participants in Wave 1 completed the Relationship Questionnaire, and those in Wave 2 completed the Social Support Questionnaire and the Youth Self-Report. Results showed that secure attachment positively predicted high levels of perceived peer support and negatively predicted internalizing problems, whereas fearful and preoccupied attachment negatively predicted perceived peer support and positively predicted internalizing problems. The mediation models showed that perceived peer support partially mediated the relationship between secure attachment and internalizing problems as well as between preoccupied attachment and internalizing problems and between fearful attachment and internalizing problems. Our results confirm the role of subjective perception of peer support in contributing to the prediction of internalizing problems beyond attachment styles.

It has been suggested that the serum soluble CD30 (sCD30) level may be a poten-tial marker for the prediction of acute allograft rejection in kidney transplant recipients. Therefore, its serum concentrations might offer a promising non-invasive tool to recognize patients with an increased risk for developing an acute graft rejection. We retrospectively correlate pre and post transplant level on post transplant graft survival, incidence of acute rejection and graft function using stored serum samples. Ninety-nine patients were divided in two separate groups: Group A in whom sample collection was done one day before transplantation and Group B where sample collection was done five days after transplantation. Younger recipients (aged less than 20 years) had higher sCD30 levels (P= 0.02). There was neither significant difference in the incidence of acute rejection nor incomplete response rate after anti rejection therapy in relation to pre transplant or post transplant sCD30. We could not find a significantly inferior graft survival rate in the high sCD30 group. In conclusion, younger patients had higher sCD30 concentrations however no correlation existed between the serum concentrations and occurrence of rejection episodes or graft survival.

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 analyse data from a trial and report the frequencies with which major and minor errors are detected at a general medical journal, the types of errors missed and the impact of training on error detection. 607 peer reviewers at the BMJ were randomized to two intervention groups receiving different types of training (face-to-face training or a self-taught package) and a control group. Each reviewer was sent the same three test papers over the study period, each of which had nine major and five minor methodological errors inserted. BMJ peer reviewers. The quality of review, assessed using a validated instrument, and the number and type of errors detected before and after training. The number of major errors detected varied over the three papers. The interventions had small effects. At baseline (Paper 1) reviewers found an average of 2.58 of the nine major errors, with no notable difference between the groups. The mean number of errors reported was similar for the second and third papers, 2.71 and 3.0, respectively. Biased randomization was the error detected most frequently in all three papers, with over 60% of reviewers rejecting the papers identifying this error. Reviewers who did not reject the papers found fewer errors and the proportion finding biased randomization was less than 40% for each paper. Editors should not assume that reviewers will detect most major errors, particularly those concerned with the context of study. Short training packages have only a slight impact on improving error detection.

The development of leisure boredom in early adolescence: Predictors and longitudinal associations with delinquency and depression.

Spaeth, Michael; Weichold, Karina; Silbereisen, Rainer K

2015-10-01

The literature proposes that leisure boredom may systematically increase during adolescence. Moreover, some authors assume that this hypothesized developmental trend is associated with increases in youthful delinquency and depression. Individual dispositions (e.g., temperamental disinhibition) are believed to exacerbate the relationship between boredom and delinquency. This study investigated whether (1) leisure boredom really is an increasing phenomenon during early adolescence; (2) gender, temperamental disinhibition, shyness, family relationship quality, peer rejection, a deprived school context, and rural/urban living explain developmental variations in boredom; (3) boredom is longitudinally and reciprocally related to delinquency and depression; and (4) bored disinhibited adolescents are particularly likely to become delinquent and to use delinquent acts to mitigate boredom. Analyses were based on a German sample of school students (N = 722) who provided annual self-reports on study variables from age 10 to 14 years. Bivariate growth curve models captured correlations between developmental trajectories of boredom and delinquency/depression. Cross-lagged models examined reciprocal short-term associations. Analyses revealed a modest increase in leisure boredom during early adolescence. Disinhibition and qualities of proximal social contexts (family, peers, school) were related to boredom with peer rejection showing the most consistent longitudinal association. Boredom was developmentally associated with depression whereas longitudinal associations with delinquency were weaker and more short-term. Temperamentally disinhibited adolescents appeared to buffer leisure boredom by means of delinquency. Results support person-context models of leisure boredom with regard to its etiology and consequences. Findings further demonstrate that leisure boredom plays a prominent role in the developmental adaptation of adolescents. (c) 2015 APA, all rights reserved).

The current study examined multilevel risk factors and developmental assets on longitudinal trajectories of aggressive behavior in a diverse sample of rural adolescents. Using ecological and social capital theories, we explored the impact of positive and negative proximal processes, social capital, and contextual characteristics (i.e., school and neighborhood) on adolescent aggression. Data came from the Rural Adaptation Project, which is a 5-year longitudinal panel study of more than 4,000 middle and high school students from 40 public schools in two rural, low income counties in North Carolina. A three-level HLM model (N = 4,056 at Wave 1, 4,251 at Wave 2, and 4,256 at Wave 3) was estimated to predict factors affecting the change trajectories of aggression. Results indicated that negative proximal processes in the form of parent-adolescent conflict, friend rejection, peer pressure, delinquent friends, and school hassles were significant predictors of aggression. In addition, social capital in the form of ethnic identity, religious orientation, and school satisfaction served as buffers against aggression. Negative proximal processes were more salient predictors than positive proximal processes. School and neighborhood characteristics had a minimal impact on aggression. Overall, rates of aggression did not change significantly over the 3-year study window. Findings highlight the need to intervene in order to decrease negative interactions in the peer and parent domains. © 2015 Wiley Periodicals, Inc.

A relational model of sexual minority mental and physical health: The negative effects of shame on relationships, loneliness, and health.

PubMed

Mereish, Ethan H; Poteat, V Paul

2015-07-01

Sexual minorities (e.g., lesbians, gay men, bisexual individuals) are at an increased risk for poorer mental and physical health outcomes than heterosexuals, and some of these health disparities relate to minority stressors such as discrimination. Yet, there is little research elucidating pathways that predict health or that promote resiliency among sexual minorities. Building on the minority stress model, the present study utilized relational cultural theory to situate sexual minority health within a relational framework. Specifically, the study tested mediators of the relationships between distal (i.e., discrimination, rejection, victimization) and proximal stressors (i.e., internalized homophobia, sexual orientation concealment) and psychological and physical distress for sexual minorities. Among 719 sexual minority adults, structural equation modeling analyses were used to test 4 models reflecting the mediating effects of shame, poorer relationships with a close peer and the lesbian/gay/bisexual/transgender (LGBT) community, and loneliness on the associations between minority stressors and psychological distress (i.e., depression and anxiety) and physical distress (i.e., distressing physical symptoms). As hypothesized, the associations between distal and proximal minority stressors and distress were mediated by shame, poorer relationships with a close peer and the LGBT community, and loneliness. Findings underscore the possible relational and interpersonal mechanisms by which sexual minority stressors lead to psychological and physical distress. (c) 2015 APA, all rights reserved).

The goal of this study was to examine the role of rejection sensitivity in the relationship between social anxiety and body dysmorphic concerns. To test our hypothesis that rejection sensitivity mediates the link between social anxiety and body dysmorphic concerns, we administered self-report questionnaires to 209 student volunteers. Consistent with our prediction, rejection sensitivity partially mediated the relationship between social anxiety symptoms and body dysmorphic concerns. The implications of the overlap between these constructs are discussed. PMID:21741203

The current study filled significant gaps in our knowledge of developmental psychopathology by examining the influence of multilevel risk factors and developmental assets on longitudinal trajectories of internalizing symptoms and self-esteem in an exceptionally culturally diverse sample of rural adolescents. Integrating ecological and social capital theories, we explored if positive microsystem transactions are associated with self-esteem while negative microsystem transactions increase the chances of internalizing problems. Data came from the Rural Adaptation Project, a 5-year longitudinal panel study of more than 4,000 middle school students from 28 public schools in two rural, disadvantaged counties in North Carolina. Three-level hierarchical linear modeling models were estimated to predict internalizing symptoms (e.g., depression, anxiety) and self-esteem. Relative to other students, risk for internalizing problems and low self-esteem was elevated for aggressive adolescents, students who were hassled or bullied at school, and those who were rejected by peers or in conflict with their parents. Internalizing problems were also more common among adolescents from socioeconomically disadvantaged families and neighborhoods, among those in schools with more suspensions, in students who reported being pressured by peers, and in youth who required more teacher support. It is likely that these experiences left adolescents disengaged from developing social capital from ecological microsystems (e.g., family, school, peers). On the positive side, support from parents and friends and optimism about the future were key assets associated with lower internalizing symptoms and higher self-esteem. Self-esteem was also positively related to religious orientation, school satisfaction, and future optimism. These variables show active engagement with ecological microsystems. The implications and limitations were discussed.

Two prospective studies examined a theoretical model wherein exposure to victimization, resulting from early behavioral risk, heightens children’s social alienation and subsequent deviant peer affiliation (DPA). Across Study 1 (298 girls, 287 boys; K – 7th grade; 5 – 12 years) and Study 2 (338 girls, 298 boys; 2nd – 6th grade; 7 – 11 years), children, parents, peers, and teachers reported on children’s externalizing behavior and internalizing symptoms, peer victimization, social alienation, and DPA. Path analyses supported the proposed pathway: Peer victimization predicted social alienation, which then predicted DPA. Early externalizing behavior set this path in motion and made an independent contribution to DPA. This research identifies an important pathway through which externalizing behavior and consequent peer victimization launch children onto a risky social trajectory. PMID:23621796

It is generally believed that parental rejection of children leads to child maladaptation. However, the specific effects of perceived parental acceptance-rejection on diverse domains of child adjustment and development have been incompletely documented, and whether these effects hold across diverse populations and for mothers and fathers are still open questions. This study assessed children's perceptions of mother and father acceptance-rejection in 1,247 families from China, Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the United States as antecedent predictors of later internalizing and externalizing behavior problems, school performance, prosocial behavior, and social competence. Higher perceived parental rejection predicted increases in internalizing and externalizing behavior problems and decreases in school performance and prosocial behavior across 3 years controlling for within-wave relations, stability across waves, and parental age, education, and social desirability bias. Patterns of relations were similar across mothers and fathers and, with a few exceptions, all nine countries. Children's perceptions of maternal and paternal acceptance-rejection have small but nearly universal effects on multiple aspects of their adjustment and development regardless of the family's country of origin. © 2014 Association for Child and Adolescent Mental Health.

Soluble CD30 as a prognostic factor for outcome following renal transplantation.

2009-07-01

To determine whether measurement of soluble CD30 (sCD30) levels predicts for early rejection in a cohort of first deceased kidney transplant recipients. Pre-transplant serum samples were analysed for sCD30 levels using a commercial ELISA kit (Biotest). A 100 U/ml cut-off for "high sCD30" was applied. Clinical outcome parameters were biopsy-proven rejection episodes, creatinine levels and glomerular filtration rate. In the cohort of patients who experienced at least one episode of rejection in the first 6 months post-transplant, levels of pre-transplant sCD30 were significantly higher than in those who did not experience rejection. Despite this association, the occurrence of a high sCD30 level did not predict for rejection on an individual basis. The prognostic value of pre-transplant sCD30 testing is diminished by the large number of patients with high sCD30 levels who do not develop rejection. Although this limits the utility of the test in informing clinical management of individual patients, a high pre-transplant sCD30 level should still be considered a risk factor for poorer outcome.

The purpose of this study was to test a hypothetical model of alcohol problems in German adolescents. Among 180 offspring, family history of alcoholism, parenting styles, behavioral and emotional problems, peer-group characteristics, feelings of self-esteem, behavioral problems and psychiatric comorbidity of the parents were examined. Data were generated from the Study of Health in Pomerania (SHIP), in which families were randomly selected if 12-18 year old biological offspring were members of the household; a smaller group of subjects was selected from local outpatient treatment centers. Members of 133 families, including 180 (50.6% male) offspring who were appropriate for the current analyses, received personal semistructured diagnostic interviews and several self-rating questionnaires. Analyses compared offspring with alcohol problems (AP; n = 40) and with no alcohol problems (NAP; n = 140), and used structural equation modeling to test a hypothetical model. The comparisons revealed that the AP group had significantly more behavioral problems (e.g., aggression/delinquency), more perceived parental rejection and less emotional warmth, a higher amount of alcohol consumption, were more likely to associate with substance-using peers and more often received a diagnosis of conduct disorder or antisocial personality disorder. Whereas the family history of alcoholism did not differ significantly between groups, parents of offspring with an alcohol use disorder had significantly more additional diagnoses on DSM-IV Axis I. The evaluation of the model supported the importance of aggression/delinquency and association with substance-using peers for alcohol problems in people. An additional diagnosis in the parents was directly and indirectly (through aggression/delinquency) related to alcohol problems of the adolescents. The data indicate that alcohol problems in the offspring are associated with several domains of influence in their environment. Prospective studies measuring both biological and environmental factors using sufficient sample sizes will be needed for optimal understanding of the development of alcohol problems in youth.

Research has indicated that not all quantitative research on the effects of interventions is disseminated or published. The extent to which qualitative researchers also systematically underreport or fail to publish certain types of research findings, and the impact this may have, has received little attention. Methods A survey was delivered online to gather data regarding non-dissemination and dissemination bias in qualitative research. We invited relevant stakeholders through our professional networks, authors of qualitative research identified through a systematic literature search, and further via snowball sampling. Results 1032 people took part in the survey of whom 859 participants identified as researchers, 133 as editors and 682 as peer reviewers. 68.1% of the researchers said that they had conducted at least one qualitative study that they had not published in a peer-reviewed journal. The main reasons for non-dissemination were that a publication was still intended (35.7%), resource constraints (35.4%), and that the authors gave up after the paper was rejected by one or more journals (32.5%). A majority of the editors and peer reviewers “(strongly) agreed” that the main reasons for rejecting a manuscript of a qualitative study were inadequate study quality (59.5%; 68.5%) and inadequate reporting quality (59.1%; 57.5%).

Bowker, Julie C.; Rubin, Kenneth H.; Laursen, Brett; Duchene, Melissa S.

2013-01-01

Rejection sensitivity, the tendency to anxiously or angrily expect rejection, is associated with internalizing difficulties during childhood and adolescence. The primary goal of the present study was to examine whether supportive parent–child relationships and friendships moderate associations that link angry and anxious rejection sensitivity to depression and social anxiety during middle adolescence in an ethnically diverse sample of 277 youth (M age = 14.30 years; 46.93% male). Analyses revealed that angry rejection sensitivity was related to depressive symptoms, but only for adolescents reporting low support from parents and friends. Friend support moderated the association between (1) angry rejection sensitivity and social anxiety, and (2) anxious rejection sensitivity and depressive symptoms. For adolescents reporting low support from friends, support from parents was positively related to social anxiety. Findings highlight the importance of considering relationships in studies of rejection sensitivity and adjustment during adolescence. PMID:20213482

This study was designed to investigate friend influence over mathematical reasoning in a sample of 374 children in 187 same-sex friend dyads (184 girls in 92 friendships; 190 boys in 95 friendships). Participants completed surveys that measured mathematical reasoning in the 3rd grade (approximately 9 years old) and 1 year later in the 4th grade (approximately 10 years old). Analyses designed for dyadic data (i.e., longitudinal actor-partner interdependence model) indicated that higher achieving friends influenced the mathematical reasoning of lower achieving friends, but not the reverse. Specifically, greater initial levels of mathematical reasoning among higher achieving partners in the 3rd grade predicted greater increases in mathematical reasoning from 3rd grade to 4th grade among lower achieving partners. These effects held after controlling for peer acceptance and rejection, task avoidance, interest in mathematics, maternal support for homework, parental education, length of the friendship, and friendship group norms on mathematical reasoning. © 2015 The British Psychological Society.

This study is designed to investigate friend influence over mathematical reasoning in a sample of 374 children in 187 same-sex friend dyads (184 girls in 92 friendships; 190 boys in 95 friendships). Participants completed surveys that measured mathematical reasoning in the 3rd grade (approximately 9 years old) and one year later in the 4th grade (approximately 10 years old). Analyses designed for dyadic data (i.e., longitudinal Actor-Partner Interdependence Models) indicated that higher achieving friends influenced the mathematical reasoning of lower achieving friends, but not the reverse. Specifically, greater initial levels of mathematical reasoning among higher achieving partners in the 3rd grade predicted greater increases in mathematical reasoning from 3rd grade to 4th grade among lower achieving partners. These effects held after controlling for peer acceptance and rejection, task avoidance, interest in mathematics, maternal support for homework, parental education, length of the friendship, and friendship group norms on mathematical reasoning.

To examine the validity of sluggish cognitive tempo (SCT) and ADHD-inattention (ADHD-IN) symptoms in children from Chile. Mothers and teachers rated SCT, ADHD-IN, ADHD-hyperactivity/impulsivity (ADHD-HI), oppositional defiant disorder (ODD), anxiety, depression, academic impairment, social impairment, and peer rejection (teachers only) in 652 Chilean children (55% boys) aged 6 to 14 years. For both mother and teacher ratings, the eight SCT symptoms and nine ADHD-IN symptoms showed substantial loadings on their respective factors (convergent validity) along with loadings close to zero on the alternative factor (discriminant validity). ADHD-IN showed a uniquely stronger relationship than SCT with ADHD-HI and ODD whereas SCT showed a uniquely stronger relationship than ADHD-IN with anxiety and depression. Although ADHD-IN uniquely predicted academic impairment and social difficulties, SCT did not. This study provides the first evidence for the validity of SCT among children outside of North America or Western Europe.

Me After You: Partner Influence and Individual Effort Predict Rejection of Self-Aspects and Self-Concept Clarity After Relationship Dissolution.

Individuals in ongoing romantic relationships incorporate attributes from their partner into their own self-concepts. However, little research has investigated what happens to these attributes should the relationship end. Across three studies, the present research sought to examine factors that predicted whether individuals retain or reject attributes from their self-concept that they initially gained during a relationship. We predicted that individuals would be more likely to reject attributes from their self post-dissolution if their ex-partner was influential in them adding those attributes to the self in the first place. However, we expected this effect to be moderated such that individuals who exerted greater, versus lesser, effort in maintaining relevant attributes would retain them as part of the self, regardless of whether the attribute originated from the partner. In addition, in two of our three studies, we explored the roles of partner influence, effort, and attribute rejection on individuals' post-dissolution self-concept clarity. © 2014 by the Society for Personality and Social Psychology, Inc.

In renal transplantation, serum soluble CD30 (sCD30) levels in graft recipients are associated with increased rejection and graft loss. We investigated whether pre-transplant sCD30 concentrations are predictive of the grade of rejection. Pre-transplant sera of 51 patients with tubulointerstitial rejection (TIR), 16 patients with vascular rejection (VR) and an age-matched control group of 41 patients with no rejection (NR) were analyzed for sCD30. The transplant biopsies were immunostained for C4d. The median sCD30 level was significantly elevated in the group with VR (248 Units (U)/mL, range: 92-802) when compared with TIR (103 U/mL, range: 36-309, p<0.001) and NR (179 U/mL, range: 70-343, p<0.03). Moreover, patients with TIR had significantly lower sCD30 levels compared to NR. Based on C4d staining, a TH2 driven process, the median sCD30 levels were significantly raised in C4d+ patients compared with C4d- group (177 U/mL vs. 120 U/mL, p<0.05). sCD30 levels measured at time of transplantation correlate with the grade of rejection. High pre-transplant levels are associated with antibody-mediated rejection which carries a poorer prognosis. sCD30 could be another tool to assess immunological risk prior to transplantation and enable a patient centered approach to immunosuppression.

Sexual compulsivity represents a significant public health concern among gay and bisexual men, given its co-occurrence with other mental health problems and HIV infection. The purpose of this study was to examine a model of sexual compulsivity based on minority stress theory and emotion regulation models of mental health among gay and bisexual men. Gay and bisexual men in New York City reporting at least nine past-90-day sexual partners (n = 374) completed measures of distal minority stressors (i.e., boyhood gender nonconformity and peer rejection, adulthood perceived discrimination), hypothesized proximal minority stress mediators (i.e., rejection sensitivity, internalized homonegativity), hypothesized universal mediators (i.e., emotion dysregulation, depression, and anxiety), and sexual compulsivity. The hypothesized model fit the data well (RMSEA = 0.05, CFI = 0.98, TLI = 0.95, SRMR = 0.03). Distal minority stress processes (e.g., adulthood discrimination) were generally found to confer risk for both proximal minority stressors (e.g., internalized homonegativity) and emotion dysregulation. Proximal minority stressors and emotion dysregulation, in turn, generally predicted sexual compulsivity both directly and indirectly through anxiety and depression. The final model suggests that gay-specific (e.g., internalized homonegativity) and universal (e.g., emotion dysregulation) processes represent potential treatment targets to attenuate the impact of minority stress on gay and bisexual men's sexual health. Tests of interventions that address these targets to treat sexual compulsivity among gay and bisexual men represent a promising future research endeavor. (c) 2015 APA, all rights reserved).

Examining the Predictive Validity of NIH Peer Review Scores

Lindner, Mark D.; Nakamura, Richard K.

2015-01-01

The predictive validity of peer review at the National Institutes of Health (NIH) has not yet been demonstrated empirically. It might be assumed that the most efficient and expedient test of the predictive validity of NIH peer review would be an examination of the correlation between percentile scores from peer review and bibliometric indices of the publications produced from funded projects. The present study used a large dataset to examine the rationale for such a study, to determine if it would satisfy the requirements for a test of predictive validity. The results show significant restriction of range in the applications selected for funding. Furthermore, those few applications that are funded with slightly worse peer review scores are not selected at random or representative of other applications in the same range. The funding institutes also negotiate with applicants to address issues identified during peer review. Therefore, the peer review scores assigned to the submitted applications, especially for those few funded applications with slightly worse peer review scores, do not reflect the changed and improved projects that are eventually funded. In addition, citation metrics by themselves are not valid or appropriate measures of scientific impact. The use of bibliometric indices on their own to measure scientific impact would likely increase the inefficiencies and problems with replicability already largely attributed to the current over-emphasis on bibliometric indices. Therefore, retrospective analyses of the correlation between percentile scores from peer review and bibliometric indices of the publications resulting from funded grant applications are not valid tests of the predictive validity of peer review at the NIH.

A plethora of studies have appeared which argue that, prior to their attack, the perpetrators of school shootings had experienced intense conflicts and problematic relations (e.g. bullying) with peers and teachers, and were on the periphery of the schools' social life. This in turn resulted in the perpetrators' view of themselves as marginalized…

Two prospective studies examined a theoretical model wherein exposure to victimization, resulting from early behavioral risk, heightens children's social alienation and subsequent deviant peer affiliation (DPA). Across Study 1 (298 girls, 287 boys; K-7th grade; 5-12 years) and Study 2 (338 girls, 298 boys; 2nd-6th grade; 8-12 years), children, parents, peers, and teachers reported on children's externalizing behavior and internalizing symptoms, peer victimization, social alienation, and DPA. Path analyses supported the proposed pathway: Peer victimization predicted social alienation, which then predicted DPA. Early externalizing behavior set this path in motion and made an independent contribution to DPA. This research identifies an important pathway through which externalizing behavior and consequent peer victimization launch children onto a risky social trajectory. © 2013 The Authors.

Witnessing peer rejection during early adolescence: Neural correlates of empathy for experiences of social exclusion

2010-01-01

Neuroimaging studies with adults have begun to reveal the neural bases of empathy; however, this research has focused on empathy for physical pain, rather than empathy for negative social experiences. Moreover, this work has not examined adolescents who may frequently witness and empathize with others who experience negative social experiences like peer rejection. Here, we examined neural activity among early adolescents observing social exclusion compared to observing inclusion, and how this activity related to both trait empathy and subsequent prosocial behavior. Participants were scanned while they observed an individual whom they believed was being socially excluded. At least one day prior to the scan they reported their trait empathy, and following the scan they wrote emails to the excluded victim that were rated for prosocial behavior (e.g., helping, comforting). Observing exclusion compared to inclusion activated regions involved in mentalizing (i.e., dorsomedial prefrontal cortex; DMPFC), particularly among highly empathic individuals. Additionally, individuals who displayed more activity in affective, pain-related regions during observed exclusion compared to inclusion subsequently wrote more prosocial emails to excluded victims. Overall findings suggest that when early adolescents witness social exclusion in their daily lives, some may actually ‘feel the pain’ of the victims and act more prosocially toward them as a result.

Although the research on cyberbullying has increased dramatically in recent years, still little is known about how cyberbullying participant groups (i.e., cyberbullies, cybervictims, and cyberbully-victims) differ from one another. This study aims to discriminate between these groups at an individual and relational level by controlling for age and gender. Self-control, offline aggression, and self-esteem are analyzed as individual-level variables. Parental attachment and peer rejection are involved as relational-level variables. A total of 2,092 Czech adolescents aged 12 to 18 were enrolled from a random sample of 34 primary and secondary schools located in the South Moravian region of the Czech Republic. Discriminant function analyses indicated that the participant groups are discriminated by two functions. The first function increases the separation between cyberbullies and cyberbully-victims from cybervictims, indicating that cyberbullies and cyberbully-victims are similar to each other in terms of low self-control, offline aggression, and gender, and have higher scores on measures of low self-esteem and offline aggression. However, cyberbully-victims had the highest scores on these measures. The second function discriminates between all three groups, which indicates that those variables included in the second function (i.e., parental attachment, peer rejection, self-esteem, and age) distinguish all three involved groups. © The Author(s) 2014.

Understanding the link between social and emotional well-being and peer relations in early adolescence: gender-specific predictors of peer acceptance.

Past studies have investigated relationships between peer acceptance and peer-rated social behaviors. However, relatively little is known about the manner in which indices of well-being such as optimism and positive affect may predict peer acceptance above and beyond peer ratings of antisocial and prosocial behaviors. Early adolescence-roughly between the ages of 9 and 14-is a time in the life span in which individuals undergo a myriad of changes at many different levels, such as changes due to cognitive development, pubertal development, and social role redefinitions. The present study investigated the relationship of self-reported affective empathy, optimism, anxiety (trait measures), and positive affect (state measure) to peer-reported peer acceptance in 99 (43% girls) 4th and 5th grade early adolescents. Because our preliminary analyses revealed gender-specific patterns, hierarchical regression analyses were conducted to investigate the predictors of peer acceptance separately for boys and for girls. Girls' acceptance of peers was significantly predicted by higher levels of empathy and optimism, and lower positive affect. For boys, higher positive affect, lower empathy, and lower anxiety significantly predicted peer acceptance. The results emphasize the importance of including indices of social and emotional well-being in addition to peer-ratings in understanding peer acceptance in early adolescence, and urge for more research on gender-specific peer acceptance.

Poor motor skills have been associated with peer relationship difficulties, with lower peer preference and greater likelihood of suffering from withdrawal and low self-worth. Most research into these relationships has focused upon children with motor problems and on activities involving physical skills (play/sport). The current study examined the link between motor performance and peer relations in 9- to 12-year-old children in both physical and non-physical (schoolwork) settings using a community sample. Participants were 192 school children whose motor performance was tested using the Movement Assessment Battery for Children. Peer acceptance was assessed using the Peer Rating Scale and teachers completed the Peer Exclusion subscale of the Child Behaviour Scale to indicate each child's peer status. Children were also asked to indicate their level of physical activity and their perceived freedom in leisure using self-report questionnaires. Children with poor motor performance had lower levels of physical activity, and freedom in leisure and were less preferred by their peers in both play and classroom settings. These effects were stronger for boys than for girls. Teacher indicated that children with poorer motor skills experienced higher levels of peer rejection in the classroom setting. When motor performance was separated into fine- and gross-motor performance it was found that only the latter was significantly correlated with peer acceptance in the play context but that fine-motor skills contributed significantly to variance in teacher ratings of peer exclusion in the classroom setting. The results support and extend earlier findings that children with poor motor performance are less accepted by their peers in play settings and provide some support for this extending to settings involving low levels of physical activity (classroom settings). The results similarly support previous findings that motor performance is associated with perceived freedom in leisure and with the likelihood of participating in active pursuits. © 2010 Blackwell Publishing Ltd.

Predicting Psychosocial Maladjustment in Emerging Adulthood From High School Experiences of Peer Victimization.

2018-01-01

The aim of the present study was to compare recollections of sexual, physical, verbal, social, and cyber peer victimization experienced in high school in terms of depressed affect, self-esteem, and loneliness experienced in university. In all, 247 university students (70 males and 177 females; M = 20.62, SD = 2.54) completed online measures assessing retrospective accounts of their experiences of different forms of peer victimization during high school (i.e., sexual, physical, verbal, social, and cyber) and their current psychosocial adjustment (i.e., self-esteem, depressed affect, and loneliness). Three separate hierarchical multiple regressions were conducted to determine whether different indices of negative psychosocial adjustment are more strongly predicted by experiencing sexual or nonsexual forms of peer victimization. Although many university students recalled experiencing sexual peer victimization in high school at least once at an even higher percentage than verbal and social forms of peer victimization, the results of the present study suggest that social peer victimization in high school predicts higher levels of depressed affect and loneliness in university students than sexual peer victimization experienced in high school. Surprisingly, the young adults reporting higher levels of cyber peer victimization in high school were less lonely in university. Although the hypothesized relationships between each form of peer victimization and specific indices of psychosocial functioning were not consistently supported, these findings suggest that the form of peer victimization matters and may be differentially associated with well-being in emerging adulthood. It is important that future research explores how individual characteristics may further predict varied experiences of peer victimization and the long-term impact of those experiences.

People tend to respond to rejection and attack with aggression. The present research examined the modulation role of attachment patterns on provoked aggression following punishment and proposed an executive functioning account of attachment patterns' modulating influence based on the General Aggression Model. Attachment style was measured using the Experiences in Close Relationships inventory. Experiments 1a and b and 2 adopted a social rejection task and assessed subsequent unprovoked and provoked aggression with different attachment patterns. Moreover, Experiment 1b and 2 used a Stroop task to examine whether differences in provoked aggression by attachment patterns are due to the amount of executive functioning following social rejection, or after unprovoked punishment, or even before social rejection. Anxiously attached participants displayed significant more provoked aggression than securely and avoidantly attached participants in provoked aggression following unprovoked punishment in Experiments 1 and 2. Meanwhile, subsequent Stroop tests indicated anxiously attached participants experienced more executive functioning depletion after social rejection and unprovoked aggression. The present findings support the General Aggression Model and suggest that provoked aggression is predicted by attachment patterns in the context of social rejection; different provoked aggression may depend on the degree of executive functioning that individuals preserved in aggressive situations. The current study contributes to our understanding of the importance of the role of attachment patterns in modulating aggressive behavior accompanying unfair social encounters. © 2017 Wiley Periodicals, Inc.

Social rejection often increases aggression, but the neural mechanisms underlying this effect remain unclear. This experiment tested whether neural activity in the dorsal anterior cingulate cortex (dACC) and anterior insula in response to social rejection predicted greater subsequent aggression. Additionally, it tested whether executive functioning moderated this relationship. Participants completed a behavioral measure of executive functioning, experienced social rejection while undergoing functional magnetic resonance imaging and then completed a task in which they could aggress against a person who rejected them using noise blasts . We found that dACC activation and executive functioning interacted to predict aggression. Specifically, participants with low executive functioning showed a positive association between dACC activation and aggression, whereas individuals with high executive functioning showed a negative association. Similar results were found for the left anterior insula. These findings suggest that social pain can increase or decrease aggression, depending on an individual's regulatory capability.

Rejection can motivate either affiliation or withdrawal. In order to study how personality and situational variables influence whether women will be motivated to affiliate versus withdraw, we manipulate social feedback (rejection vs. acceptance) and opportunity for face-to-face interaction (blocked vs. face-to-face) and measure the individual difference variables rejection sensitivity and social anxiety. We test how these variables affect endogenous progesterone and cortisol concentrations, which are presumed to signal motivational responses to rejection. We find that three-way interactions involving social feedback, opportunity for face-to-face interactions, and either social anxiety or rejection sensitivity significantly predict progesterone change, but not cortisol change. Both interactions are driven by sharp progesterone decreases for women high in social anxiety/rejection sensitivity who have been rejected and who have no opportunity to reaffiliate in a face-to-face interaction. This progesterone change may be a physiological marker of motivation for social avoidance following rejection for women who cannot reaffiliate and who are particularly socially anxious or sensitive to rejection.

We examined change processes associated with the school-based, lunchtime mentoring of bullied children. We used data from a one-semester open trial of Lunch Buddy (LB) mentoring (N = 24) to examine changes in bullied children's lunchtime peer relationships. We also tested whether these changes predicted key outcomes (i.e., peer victimization, social preference) post-mentoring. Results provided partial support that bullied children paired with LB mentors experienced improved lunchtime peer relationships and that gains in lunchtime relationships predicted post-mentoring levels of social preference and peer victimization. Neither child nor mentors' ratings of the mentoring relationship predicted post-mentoring outcomes; however, child-rated mentor support and conflict predicted improvements in lunchtime peer relationships. We discuss implications for future research on school-based mentoring as a form of selective intervention for bullied children.

2006-06-01

To evaluate the feasibility of serum sCD30 for prediction of acute graft rejection, we analyzed clinical data of 231 patients, whose serum levels of sCD30 were detected by ELISA before and after transplantation. They were divided into three groups: acute rejection group (AR, n = 49), uncomplicated course group (UC, n = 171) and delayed graft function group (DGF, n = 11). Preoperative sCD30 levels of three groups were 183 +/- 74, 177 +/- 82 and 168 +/- 53 U/ml, respectively (P = 0.82). Significant decrease of sCD30 was detected in three groups on day 5 and 10 post-transplantation respectively (52 +/- 30 and 9 +/- 5 U/ml respectively, P < 0.001). Compared with Group UC and DGF, patients of Group AR had higher sCD30 values on day 5 post-transplantation (92 +/- 27 U/ml vs. 41 +/- 20 U/ml and 48 +/- 18 U/ml, P < 0.001). However, sCD30 levels on day 10 post-transplantation were virtually similar in patients of three groups (P = 0.43). Receiver operating characteristic (ROC) curve demonstrated that sCD30 level on day 5 post-transplantation could differentiate patients who subsequently suffered acute allograft rejection from others (area under ROC curve 0.95). According to ROC curve, 65 U/ml may be the optimal operational cut-off level to predict impending graft rejection (specificity 91.8%, sensitivity 87.1%). Measurement of soluble CD30 on day 5 post-transplantation might offer a noninvasive means to recognize patients at risk of impending acute graft rejection during early post-transplantation period.

Why school students choose and reject science: a study of the factors that students consider when selecting subjects

Student study of science at school has been linked to the need to provide a scientifically capable workforce and a scientifically literate society. Educators, scientists, and policymakers are concerned that too few students are choosing science for study in their final years of school. How and why students choose and reject certain subjects, including science, at this time is unclear. A Best-Worst Scaling (BWS) survey was completed by 333 Year 10 (age 14-17) students to investigate the relative importance of 21 factors thought to impact students' subject-selection decisions. Students ranked enjoyment, interest and ability in a subject, and its perceived need in their future study or career plans as the most important factors in both choosing and rejecting subjects. They considered advice from teachers, parents or peers as relatively less important. These findings indicate that enhancing students' enjoyment, interest, and perceptions of their ability in science, as well as increasing student perceptions of its value in a future career, may result in more students studying science at school.

The implementation of research findings into healthcare practice has become increasingly recognised as a major priority for researchers, service providers, research funders and policymakers over the past decade. Nine years after its establishment, Implementation Science, an international online open access journal, currently publishes over 150 articles each year. This is fewer than 30% of those submitted for publication. The majority of manuscript rejections occur at the point of initial editorial screening, frequently because we judge them to fall outside of journal scope. There are a number of common reasons as to why manuscripts are rejected on grounds of scope. Furthermore, as the field of implementation research has evolved and our journal submissions have risen, we have, out of necessity, had to become more selective in what we publish. We have also expanded our scope, particularly around patient-mediated and population health interventions, and will monitor the impact of such changes. We hope this editorial on our evolving priorities and common reasons for rejection without peer review will help authors to better judge the relevance of their papers to Implementation Science.

High serum soluble CD30 does not predict acute rejection in liver transplant patients.

2006-12-01

Increased pre- and posttransplantation values of soluble CD30 (sCD30) have been shown to be associated with acute kidney transplant rejection. We sought to study whether high sCD30 could predict rejection early after liver transplantation. The study population included 54 consecutive liver transplant patients, whose samples were collected before liver transplantation and at discharge, which was at a mean time of 3 weeks after transplantation. During the first 6 months posttransplantation, 22 patients experienced an acute rejection episode. Serum sCD30 concentrations were measured by an enzyme-linked immunoassay; changes in serum sCD30 levels posttransplantation were also expressed as relative values compared with pretransplantation results. Liver patients before transplantation displayed higher serum sCD30 values compared with healthy controls: mean values +/- SD were 93 +/- 58 IU/mL vs 17 +/- 8 IU/mL, respectively. At 3 weeks after transplantation the mean sCD30 concentration in liver transplant patients decreased to 59 +/- 42 IU/mL (P = .005). The mean pretransplantation serum sCD30 value was slightly lower among rejecting vs nonrejecting patients: 78 +/- 43 IU/mL vs 104 +/- 65 IU/mL (P = NS). Posttransplantation values in both groups decreased significantly: 47 +/- 34 IU/mL in patients with rejection (P = .014) vs 69 +/- 45 IU/mL in patients without rejection (P = .012). The relative value at 3 weeks posttransplantation decreased slightly more among patients with vs without rejection (70% vs 88%; NS). No correlation was found between serum sCD30 and anti-HLA class I antibodies or crossmatch positivity. In conclusion, neither pre- nor posttransplantation sCD30 levels were associated with acute rejection in liver transplant patients.

Heart-rate deceleration predicting the determination of costly punishment: Implications for its involvement in cognitive effort expended in overriding self-interest.

PubMed

Osumi, Takahiro; Ohira, Hideki

2016-11-01

Previous studies have investigated which biological markers predict the decision to reject unfair monetary offers, termed costly punishment, in the ultimatum game (UG). One study showed that a phasic deceleratory response in heart rate (HR) is evoked in the responder more readily by offers that will be rejected than by offers that will be accepted. However, owing to the paucity of supporting evidence, it remains unclear whether and why HR deceleration can predict the decisions of UG responders. In this paper, we report two separate studies (Study 1 and Study 2) using modified versions of the UG to explore factors modulating HR deceleration. In Study 1, as well as unfair offers, fair offers induced greater HR deceleration when responders were forced to reject offers compared to when they were forced to accept offers. In Study 2, a high rejection rate for very unfair offers was sustained, regardless of the size of the offers, but HR deceleration was increased for unfair but large offers, relative to unfair, small offers. Moreover, HR deceleration was associated with the rejection of large offers. However, across the two studies, HR deceleration did not simply vary depending on unfairness. These findings support the possibility that HR decelerates as a function of cognitive load in determining costly punishment. Copyright © 2016 Elsevier B.V. All rights reserved.

The aim of the present study was to identify whether the serum interferon-gamma (IFNgamma), a Th1 cytokine, or soluble CD30 (sCD30), a marker for activation of Th2 cytokine-producing T cells, predict acute cellular rejection episodes among liver graft patients. Pretransplant and posttransplant sera from 32 living donor liver transplant recipients obtained on days 1, 3, and 7 after surgery were tested for serum IFNgamma and sCD30 concentrations using commercial enzyme-linked immunosorbent assay kits. Recipients with an acute rejection episode (ARE) (n=14) displayed significantly higher IFNgamma concentrations pretransplant than did the patients with no ARE (n=18) (P<.05). The pretransplant serum levels of sCD30 were not different between the non-ARE and ARE groups. However, in comparison with the non-ARE group, who showed steadily decreasing serum sCD30 levels after transplantation, 12 among the 14 patients in the ARE group showed increasing sCD30 levels from day 1 to day 3 after transplantation (P<.05). These results suggest that the sCD30 increment during the early period after liver transplantation affects the immune response of rejection. This observation emphasizes the clinical relevance of serum sCD30, in addition to serum IFNgamma, as predictive markers for acute liver graft rejection.

Defensive Physiological Reactions to Rejection

We examined the hypothesis that rejection automatically elicits defensive physiological reactions in people with low self-esteem (SE) but that attentional control moderates this effect. Undergraduates (N = 67) completed questionnaire measures of SE and attentional control. Their eye-blink responses to startle probes were measured while they viewed paintings related to rejection and acceptance themes. The stimuli also included positive-, negative-, and neutral-valence control paintings unrelated to rejection. As predicted, compared with people high in SE, those low in SE showed stronger startle eye-blink responses to paintings related to rejection, but not to negative paintings. Paintings related to acceptance did not attenuate their physiological reactivity. Furthermore, attentional control moderated their sensitivity to rejection, such that low SE was related to greater eye-blink responses to rejection only among individuals who were low in attentional control. Implications of the role of attentional control as a top-down process regulating emotional reactivity in people with low SE are discussed. PMID:17894606

"I'm worth more than that": trait positivity predicts increased rejection of unfair financial offers.

Humans react strongly to unfairness, sometimes rejecting inequitable proposals even if this sacrifices personal financial gain. Here we explored whether emotional dispositions--trait tendencies to experience positive or negative feelings--shape the rejection of unfair financial offers. Participants played an Ultimatum Game, where the division of a sum of money is proposed and the player can accept or reject this offer. Individuals high in trait positivity and low in trait negativity rejected more unfair offers. These relationships could not be explained by existing accounts which argue that rejection behaviour results from a failure to regulate negative emotions, or serves to arbitrate social relationships and identity. Instead, the relationship between dispositional affect and rejection behaviour may be underpinned by perceived self worth, with those of a positive disposition believing that they are "worth more than that" and those of a negative disposition resigning themselves to "taking the crumbs from under the table".

Reactions to Discrimination, Stigmatization, Ostracism, and Other Forms of Interpersonal Rejection

This article describes a new model that provides a framework for understanding people’s reactions to threats to social acceptance and belonging as they occur in the context of diverse phenomena such as rejection, discrimination, ostracism, betrayal, and stigmatization. People’s immediate reactions are quite similar across different forms of rejection in terms of negative affect and lowered self-esteem. However, following these immediate responses, people’s reactions are influenced by construals of the rejection experience that predict 3 distinct motives for prosocial, antisocial, and socially avoidant behavioral responses. The authors describe the relational, contextual, and dispositional factors that affect which motives determine people’s reactions to a rejection experience and the ways in which these 3 motives may work at cross-purposes. The multimotive model accounts for the myriad ways in which responses to rejection unfold over time and offers a basis for the next generation of research on interpersonal rejection. PMID:19348546

The debate on whether the peer-review system is in crisis has been heated recently. A variety of alternative systems have been proposed to improve the system and make it sustainable. However, we lack sufficient evidence and data related to these issues. Here we used a previously developed agent-based model of the scientific publication and peer-review system calibrated with empirical data to compare the efficiency of five alternative peer-review systems with the conventional system. We modelled two systems of immediate publication, with and without online reviews (crowdsourcing), a system with only one round of reviews and revisions allowed (re-review opt-out) and two review-sharing systems in which rejected manuscripts are resubmitted along with their past reviews to any other journal (portable) or to only those of the same publisher but of lower impact factor (cascade). The review-sharing systems outperformed or matched the performance of the conventional one in all peer-review efficiency, reviewer effort and scientific dissemination metrics we used. The systems especially showed a large decrease in total time of the peer-review process and total time devoted by reviewers to complete all reports in a year. The two systems with immediate publication released more scientific information than the conventional one but provided almost no other benefit. Re-review opt-out decreased the time reviewers devoted to peer review but had lower performance on screening papers that should not be published and relative increase in intrinsic quality of papers due to peer review than the conventional system. Sensitivity analyses showed consistent findings to those from our main simulations. We recommend prioritizing a system of review-sharing to create a sustainable scientific publication and peer-review system.

The Editors of the Journal of Geophysical Research Space Physics are deeply indebted to the many people among the research community that serve this journal through peer review. The journal could not exist without the time and effort invested by the community through this voluntary activity, providing expert evaluations and thoughtful assessments of the work of others. In 2015, the journal had 1506 scientists contribute to the process with at least one peer review, for a total of 3575 reviews completed, including additional reviews of resubmitted manuscripts. There were 277 reviewers that contributed four or more reports in 2015. The average number of reviews per referee in 2015 was, therefore, 2.4. Note that the total number of manuscript final decisions (i.e., accept or reject) for Journal of Geophysical Research (JGR) Space Physics was 1147 in 2015. Of this, 774 were accepted and 373 were declined, for an acceptance rate of 67% last year. If the 1334 "revision" decisions are included in the tally, then the total number of decisions made in 2015 was 2481. Working out the arithmetic, it means that on average, a manuscript gets about 1.2 revision decisions before a final accept-or-reject decision. This explains the 3.1 average number of reviews per manuscript throughout each paper's lifetime in the submission-revision editorial process. We are pleased and happy that the research community is willing and able to devote their resources toward this service endeavor. We appreciate each and every one of you that helped maintain the high quality of papers in JGR Space Physics last year. We look forward to another excellent year working with all of you through the year ahead.

Despite the widely recognised importance of sustainable health care systems, health services research remains generally underfunded in Australia. The Australian Centre for Health Services Innovation (AusHSI) is funding health services research in the state of Queensland. AusHSI has developed a streamlined protocol for applying and awarding funding using a short proposal and accelerated peer review. An observational study of proposals for four health services research funding rounds from May 2012 to November 2013. A short proposal of less than 1,200 words was submitted using a secure web-based portal. The primary outcome measures are: time spent preparing proposals; a simplified scoring of grant proposals (reject, revise or accept for interview) by a scientific review committee; and progressing from submission to funding outcomes within eight weeks. Proposals outside of health services research were deemed ineligible. There were 228 eligible proposals across 4 funding rounds: from 29% to 79% were shortlisted and 9% to 32% were accepted for interview. Success rates increased from 6% (in 2012) to 16% (in 2013) of eligible proposals. Applicants were notified of the outcomes within two weeks from the interview; which was a maximum of eight weeks after the submission deadline. Applicants spent 7 days on average preparing their proposal. Applicants with a ranking of reject or revise received written feedback and suggested improvements for their proposals, and resubmissions composed one third of the 2013 rounds. The AusHSI funding scheme is a streamlined application process that has simplified the process of allocating health services research funding for both applicants and peer reviewers. The AusHSI process has minimised the time from submission to notification of funding outcomes.

Which egg features predict egg rejection responses in American robins? Replicating Rothstein's (1982) study.

Rothstein (Behavioral Ecology and Sociobiology, 11, 1982, 229) was one of the first comprehensive studies to examine how different egg features influence egg rejection behaviors of avian brood parasite-hosts. The methods and conclusions of Rothstein (1982) laid the foundation for subsequent experimental brood parasitism studies over the past thirty years, but its results have never been evaluated with replication. Here, we partially replicated Rothstein's (1982) experiments using parallel artificial model egg treatments to simulate cowbird ( Molothrus ater ) parasitism in American robin ( Turdus migratorius ) nests. We compared our data with those of Rothstein (1982) and confirmed most of its original findings: (1) robins reject model eggs that differ from the appearance of a natural robin egg toward that of a natural cowbird egg in background color, size, and maculation; (2) rejection responses were best predicted by model egg background color; and (3) model eggs differing by two or more features from natural robin eggs were more likely to be rejected than model eggs differing by one feature alone. In contrast with Rothstein's (1982) conclusion that American robin egg recognition is not specifically tuned toward rejection of brown-headed cowbird eggs, we argue that our results and those of other recent studies of robin egg rejection suggest a discrimination bias toward rejection of cowbird eggs. Future work on egg recognition will benefit from utilizing a range of model eggs varying continuously in background color, maculation patterning, and size in combination with avian visual modeling, rather than using model eggs which vary only discretely.

Rejection sensitivity moderates the impact of rejection on self-concept clarity.

Ayduk, Ozlem; Gyurak, Anett; Luerssen, Anna

2009-11-01

Self-concept clarity (SCC) refers to the extent to which self-knowledge is clearly and confidently defined, internally consistent, and temporally stable. Research shows that SCC can be undermined by failures in valued goal domains. Because preventing rejection is an important self-relevant goal for people high in rejection sensitivity (RS), it is hypothesized here that failures to attain this goal would cause them to experience diminished SCC. Study 1, an experimental study, showed that high-RS people's SCC was undermined following rejection but not following an aversive experience unrelated to rejection. Study 2, a daily diary study of couples in relationships, used occurrence of partner conflicts to operationalize rejection. Replicating the findings in Study 1, having a conflict on any given diary day predicted a greater reduction in the SCC of high- compared to low-RS people on the following day. The implications for understanding the conditions under which rejection negatively affects the self-concept are discussed.

Mass Transport through Nanostructured Membranes: Towards a Predictive Tool

2016-01-01

This study proposes a new mechanism to understand the transport of solvents through nanostructured membranes from a fundamental point of view. The findings are used to develop readily applicable mathematical models to predict solvent fluxes and solute rejections through solvent resistant membranes used for nanofiltration. The new model was developed based on a pore-flow type of transport. New parameters found to be of fundamental importance were introduced to the equation, i.e., the affinity of the solute and the solvent for the membrane expressed as the hydrogen-bonding contribution of the solubility parameter for the solute, solvent and membrane. A graphical map was constructed to predict the solute rejection based on the hydrogen-bonding contribution of the solubility parameter. The model was evaluated with performance data from the literature. Both the solvent flux and the solute rejection calculated with the new approach were similar to values reported in the literature.

Ethics of reviewing scientific publications.

Napolitani, Federica; Petrini, Carlo; Garattini, Silvio

2017-05-01

The approval or rejection of scientific publications can have important consequences for scientific knowledge, so considerable responsibility lies on those who have to assess or review them. Today it seems that the peer review process, far from being considered an outdated system to be abandoned, is experiencing a new upturn. This article proposes criteria for the conduct of reviewers and of those who select them. While commenting on new emerging models, it provides practical recommendations for improving the peer-review system, like strengthening the role of guidelines and training and supporting reviewers. The process of peer review is changing, it is getting more open and collaborative, but those same ethical principles which guided it from its very origin should remain untouched and be firmly consolidated. The paper highlights how the ethics of reviewing scientific publications is needed now more than ever, in particular with regard to competence, conflict of interest, willingness to discuss decisions, complete transparency and integrity.

Mental Health and the Transgender Population.

Carmel, Tamar C; Erickson-Schroth, Laura

2016-12-01

Although research into the physical and mental health disparities faced by transgender and gender nonconforming (TGNC) populations is becoming more popular, historically it has been limited. It is now recognized that TGNC people experience disproportionate rates of negative mental health outcomes relative to both their gender-normative, heterosexual peers, as well as their gender-normative lesbian, gay, and bisexual (LGB) peers. The theoretical basis of current transgender mental health research is rooted in the Minority Stress Model, which postulates that we live in a hetero-centric, gender-normative society that stigmatizes and discriminates against lesbian, gay, bisexual, and transgender (LGBT) people, subjecting them to chronic stress (Hendricks & Testa, 2012; Meyer, 1995). This chronic, potentially compounding stress, is responsible for the increased risk of negative mental health outcomes in LGBT populations. TGNC people, in particular, may experience more adverse outcomes than their LGB peers due to rejection and discrimination within society at large as well as within the LGB community.

The role of egg-nest contrast in the rejection of brood parasitic eggs.

PubMed

Aidala, Zachary; Croston, Rebecca; Schwartz, Jessica; Tong, Lainga; Hauber, Mark E

2015-04-15

Hosts of avian brood parasites can avoid the reproductive costs of raising genetically unrelated offspring by rejecting parasitic eggs. The perceptual cues and controls mediating parasitic egg discrimination and ejection are well studied: hosts are thought to use differences in egg color, brightness, maculation, size and shape to discriminate between their own and foreign eggs. Most theories of brood parasitism implicitly assume that the primary criteria to which hosts attend when discriminating eggs are differences between the eggs themselves. However, this assumption is confounded by the degree to which chromatic and achromatic characteristics of the nest lining co-vary with egg coloration, so that egg-nest contrast per se might be the recognition cue driving parasitic egg detection. Here, we systematically tested whether and how egg-nest contrast itself contributes to foreign egg discrimination. In an artificial parasitism experiment, we independently manipulated egg color and nest lining color of the egg-ejector American robin (Turdus migratorius), a host of the obligate brood parasitic brown-headed cowbird (Molothrus ater). We hypothesized that the degree of contrast between foreign eggs and the nest background would affect host egg rejection behavior. We predicted that experimentally decreasing egg-nest chromatic and achromatic contrast (i.e. rendering parasitic eggs more cryptic against the nest lining) would decrease rejection rates, while increasing egg-nest contrast would increase rejection rates. In contrast to our predictions, egg-nest contrast was not a significant predictor of egg ejection patterns. Instead, egg color significantly predicted responses to parasitism. We conclude that egg-egg differences are the primary drivers of egg rejection in this system. Future studies should test for the effects of egg-nest contrast per se in predicting parasitic egg recognition in other host-parasite systems, including those hosts building enclosed nests and those parasites laying cryptic eggs, as an alternative to hypothesized effects of egg-egg contrast. © 2015.

2004-06-03

This final report of ''Modified Reverse Osmosis System for Treatment of Produced Water,'' DOE project No. DE-FC26-00BC15326 describes work performed in the third year of the project. Several good results were obtained, which are documented in this report. The compacted bentonite membranes were replaced by supported bentonite membranes, which exhibited the same salt rejection capability. Unfortunately, it also inherited the clay expansion problem due to water invasion into the interlayer spaces of the compacted bentonite membranes. We noted that the supported bentonite membrane developed in the project was the first of its kind reported in the literature. An {alpha}-alumina-supported MFI-typemore » zeolite membrane synthesized by in-situ crystallization was fabricated and tested. Unlike the bentonite clay membranes, the zeolite membranes maintained stability and high salt rejection rate even for a highly saline solution. Actual produced brines from gas and oil fields were then tested. For gas fields producing brine, the 18,300 ppm TDS (total dissolved solids) in the produced brine was reduced to 3060 ppm, an 83.3% rejection rate of 15,240 ppm salt rejection. For oilfield brine, while the TDS was reduced from 181,600 ppm to 148,900 ppm, an 18% rejection rate of 32,700 ppm reduction, the zeolite membrane was stable. Preliminary results show the dissolved organics, mainly hydrocarbons, did not affect the salt rejection. However, the rejection of organics was inconclusive at this point. Finally, the by-product of this project, the {alpha}-alumina-supported Pt-Co/Na Y catalytic zeolite membrane was developed and demonstrated for overcoming the two-step limitation of nonoxidation methane (CH{sub 4}) conversion to higher hydrocarbons (C{sub 2+}) and hydrogen (H{sub 2}). Detailed experiments to obtain quantitative results of H{sub 2} generation for various conditions are now being conducted. Technology transfer efforts included five manuscripts submitted to peer-reviewed journals and five conference presentations.« less

A noninvasive biomarker that could accurately diagnose acute rejection (AR) in heart transplant recipients could obviate the need for surveillance endomyocardial biopsies. We assessed the performance metrics of a novel high-sensitivity cardiac troponin I (cTnI) assay for this purpose. Stored serum samples were retrospectively matched to endomyocardial biopsies in 98 cardiac transplant recipients, who survived ≥3 months after transplant. AR was defined as International Society for Heart and Lung Transplantation grade 2R or higher cellular rejection, acellular rejection, or allograft dysfunction of uncertain pathogenesis, leading to treatment for presumed rejection. cTnI was measured with a high-sensitivity assay (Abbott Diagnostics, Abbott Park, IL). Cross-sectional analyses determined the association of cTnI concentrations with rejection and International Society for Heart and Lung Transplantation grade and the performance metrics of cTnI for the detection of AR. Among 98 subjects, 37% had ≥1 rejection episode. cTnI was measured in 418 serum samples, including 35 paired to a rejection episode. cTnI concentrations were significantly higher in rejection versus nonrejection samples (median, 57.1 versus 10.2 ng/L; P<0.0001) and increased in a graded manner with higher biopsy scores (P(trend)<0.0001). The c-statistic to discriminate AR was 0.82 (95% confidence interval, 0.76-0.88). Using a cut point of 15 ng/L, sensitivity was 94%, specificity 60%, positive predictive value 18%, and negative predictive value 99%. A high-sensitivity cTnI assay seems useful to rule out AR in cardiac transplant recipients. If validated in prospective studies, a strategy of serial monitoring with a high-sensitivity cTnI assay may offer a low-cost noninvasive strategy for rejection surveillance. © 2014 American Heart Association, Inc.

Selection and Socialization Effects in Early Adolescent Alcohol Use: A Propensity Score Analysis

The robust correlation between peer and adolescent alcohol use (AU) has been taken as evidence for both socialization and selection processes in the etiology of adolescent AU. Accumulating evidence from studies using a diverse range of methodological and statistical approaches suggests that both processes are involved. A major challenge in testing whether peer AU predicts an adolescent's drinking (socialization) or whether an adolescent's drinking predicts peer AU (selection) is the myriad of potentially confounding factors that might lead to an overestimation of socialization and selection effects. After creating AU transition groups based on peer and adolescent AU across two waves (N = 765; age = 10-15; 53% female), we test whether transitions into AU by adolescents and peers predict later peer and adolescent AU respectively, using (1) propensity score analysis to balance transition groups on 26 potential confounds, (2) a longitudinal design with three waves to establish temporal precedence, and (3) both adolescent (target) and peer self-report of peer AU to disentangle effects attributable to shared reporter bias. Both selection and socialization were supported using both peer self-report of AU and adolescent-report of peer AU. Although cross-sectional analyses suggested peer self-reported models were associated with smaller effects than perceived peer AU, longitudinal analyses suggest a similar sized effect across reporter of peer AU for both selection and socialization. The implications of these findings for the etiology and treatment of adolescent AU are discussed. PMID:25601099

Different recognition cues reveal the decision rules used for egg rejection by hosts of a variably mimetic avian brood parasite.

Brood parasitism imposes several fitness costs on the host species. To reduce these costs, hosts of avian brood parasites have evolved various defenses, of which egg rejection is the most prevalent. In the face of variable host-parasite mimicry and the costs of egg discrimination itself, many hosts reject only some foreign eggs. Here, we experimentally varied the recognition cues to study the underlying cognitive mechanisms used by the Chalk-browed Mockingbird (Mimus saturninus) to reject the white immaculate eggs laid by the parasitic Shiny Cowbird (Molothrus bonariensis). Immaculate eggs are the only parasite eggs rejected by this host, as it accepts all polymorphic, spotted eggs laid by cowbirds. Using a within-breeding pair experimental design, we tested for the salience of spotting, UV reflectance, and brightness in eliciting rejection. We found that the presence of spotting significantly decreased the probability of rejection while increments in brightness significantly increased rejection frequencies. The cognitive rules underlying mockingbird rejection behavior can be explained by a decision-making model which predicts changes in the levels of rejection in direct relation to the number of relevant attributes shared between host and parasite eggs.

To examine the process and emotional effect of disclosing a personal diagnosis of Mayer-Rokitansky-Küster-Hauser syndrome (MRKH) to peers during adolescence and young adulthood. Qualitative study using semistructured telephone interviews. Nine women diagnosed with MRKH, aged 21-31 years, recruited via patient support groups. Motivators and barriers to self-disclosure of a diagnosis of MRKH to peers and partners. Motivators to tell peers about a diagnosis included significant trust in the relationship (whether platonic or romantic), needing to unload the experienced burden of diagnosis, and a sense of responsibility to be forthcoming if a long-term romantic future was desired. The most common barrier to telling others was fear of rejection or being labeled a "freak." Although most participants did not receive guidance from a health care provider regarding approaches to sharing diagnostic information with others, almost all participants reported wishing they had received such counseling. A diagnosis of MRKH elicits recurring anxieties about disclosure and the effect on relationships that are inadequately addressed by health care providers. Guidance and support on disclosure to friends and romantic partners should be provided whenever possible. Copyright © 2016 North American Society for Pediatric and Adolescent Gynecology.

Although the receipt of peer sexual harassment in schools has been linked to deliberate self-injury, the direction of association over time has not been tested. Two longitudinal studies examined whether receipt of peer sexual harassment within schools predicts engagement in deliberate self-injury or vice versa. Differences between boys and girls were also tested. Surveys were conducted in two countries, Canada and Sweden. Measures of sexual harassment and deliberate self-injury were administered yearly in classrooms. Two waves of data were collected in the Canadian study (N = 161, 59.6% girls, mean age = 13.82 years); three waves of data were collected in Sweden (N = 513, 47% girls, mean age = 13.23 years). In the Canadian study, deliberate self-injury predicted subsequent peer sexual harassment; the converse relationship was not significant. No significant gender differences were found. Across the three waves of the Swedish study, peer sexual harassment predicted self-injury from T1 to T2, and self-injury predicted peer sexual harassment from T2 to T3. However, self-injury did not mediate peer sexual harassment at T1 and T3. Tests of gender differences revealed self-injury predicted sexual harassment from T2 to T3 among Swedish girls but not boys. Adolescents who deliberately self-injure may be vulnerable to sexual harassment by peers at school. Cultural norms may have a role in whether this process applies primarily to girls or to both genders. Sexual harassment by peers may also increase self-injury, but this is not subsequently linked to increases in receipt of sexual harassment.

The influence of structural stigma and rejection sensitivity on young sexual minority men's daily tobacco and alcohol use

2018-01-01

Stigma occurs at both individual and structural levels, but existing research tends to examine the effect of individual and structural forms of stigma in isolation, rather than considering potential synergistic effects. To address this gap, our study examined whether stigma at the individual level, namely gay-related rejection sensitivity, interacts with structural stigma to predict substance use among young sexual minority men. Sexual minority (n = 119) participants completed online measures of our constructs (e.g., rejection sensitivity). Participants currently resided across a broad array of geographic areas (i.e., 24 U.S. states), and had attended high school in 28 states, allowing us to capture sufficient variance in current and past forms of structural stigma, defined as (1) a lack of state-level policies providing equal opportunities for heterosexual and sexual minority individuals and (2) negative state-aggregated attitudes toward sexual minorities. To measure daily substance use, we utilized a daily diary approach, whereby all participants were asked to indicate whether they used tobacco or alcohol on nine consecutive days. Results indicated that structural stigma interacted with rejection sensitivity to predict tobacco and alcohol use, and that this relationship depended on the developmental timing of exposure to structural stigma. In contrast, rejection sensitivity did not mediate the relationship between structural stigma and substance use. These results suggest that psychological predispositions, such as rejection sensitivity, interact with features of the social environment, such as structural stigma, to predict important health behaviors among young sexual minority men. These results add to a growing body of research documenting the multiple levels through which stigma interacts to produce negative health outcomes among sexual minority individuals. PMID:24507912

Statistical Reviewers Improve Reporting in Biomedical Articles: A Randomized Trial

2007-01-01

Background Although peer review is widely considered to be the most credible way of selecting manuscripts and improving the quality of accepted papers in scientific journals, there is little evidence to support its use. Our aim was to estimate the effects on manuscript quality of either adding a statistical peer reviewer or suggesting the use of checklists such as CONSORT or STARD to clinical reviewers or both. Methodology and Principal Findings Interventions were defined as 1) the addition of a statistical reviewer to the clinical peer review process, and 2) suggesting reporting guidelines to reviewers; with “no statistical expert” and “no checklist” as controls. The two interventions were crossed in a 2×2 balanced factorial design including original research articles consecutively selected, between May 2004 and March 2005, by the Medicina Clinica (Barc) editorial committee. We randomized manuscripts to minimize differences in terms of baseline quality and type of study (intervention, longitudinal, cross-sectional, others). Sample-size calculations indicated that 100 papers provide an 80% power to test a 55% standardized difference. We specified the main outcome as the increment in quality of papers as measured on the Goodman Scale. Two blinded evaluators rated the quality of manuscripts at initial submission and final post peer review version. Of the 327 manuscripts submitted to the journal, 131 were accepted for further review, and 129 were randomized. Of those, 14 that were lost to follow-up showed no differences in initial quality to the followed-up papers. Hence, 115 were included in the main analysis, with 16 rejected for publication after peer review. 21 (18.3%) of the 115 included papers were interventions, 46 (40.0%) were longitudinal designs, 28 (24.3%) cross-sectional and 20 (17.4%) others. The 16 (13.9%) rejected papers had a significantly lower initial score on the overall Goodman scale than accepted papers (difference 15.0, 95% CI: 4.6–24.4). The effect of suggesting a guideline to the reviewers had no effect on change in overall quality as measured by the Goodman scale (0.9, 95% CI: −0.3–+2.1). The estimated effect of adding a statistical reviewer was 5.5 (95% CI: 4.3–6.7), showing a significant improvement in quality. Conclusions and Significance This prospective randomized study shows the positive effect of adding a statistical reviewer to the field-expert peers in improving manuscript quality. We did not find a statistically significant positive effect by suggesting reviewers use reporting guidelines. PMID:17389922

Vulnerability to Peer Influence: A Moderated Mediation Study of Early Adolescent Alcohol Use Initiation

Affiliation with deviant peers is a correlate of adolescent alcohol use; however, the mechanism accounting for this association remains unclear, particularly with respect to initiation of alcohol use in early adolescence. This prospective study examines perceived peer attitudes and use as a mediator between peer delinquency and initiation of alcohol use, and how parenting may moderate vulnerability to this risk pathway. Participants included 371 11–13 year-old adolescents (55.5% female, 83.0% Caucasian). Results suggested that high levels of peer delinquency prospectively predicted perceived peer approval and use of alcohol and that peer approval and use of alcohol prospectively predicted initiation of alcohol use. Thus, reinforcement and modeling alcohol use appear to be important mechanisms by which delinquent peers influence the initiation of drinking. There was no support for parental warmth or control as moderators of peer influence. PMID:21420241

The stylar 120 kDa glycoprotein is required for S-specific pollen rejection in Nicotiana.

S-RNase participates in at least three mechanisms of pollen rejection. It functions in S-specific pollen rejection (self-incompatibility) and in at least two distinct interspecific mechanisms of pollen rejection in Nicotiana. S-specific pollen rejection and rejection of pollen from Nicotiana plumbaginifolia also require additional stylar proteins. Transmitting-tract-specific (TTS) protein, 120 kDa glycoprotein (120K) and pistil extensin-like protein III (PELP III) are stylar glycoproteins that bind S-RNase in vitro and are also known to interact with pollen. Here we tested whether these glycoproteins have a direct role in pollen rejection. 120K shows the most polymorphism in size between Nicotiana species. Larger 120K-like proteins are often correlated with S-specific pollen rejection. Sequencing results suggest that the polymorphism primarily reflects differences in glycosylation, although indels also occur in the predicted polypeptides. Using RNA interference (RNAi), we suppressed expression of 120K to determine if it is required for S-specific pollen rejection. Transgenic SC N. plumbaginifolia x SI Nicotiana alata (S105S105 or SC10SC10) hybrids with no detectable 120K were unable to perform S-specific pollen rejection. Thus, 120K has a direct role in S-specific pollen rejection. However, suppression of 120K had no effect on rejection of N. plumbaginifolia pollen. In contrast, suppression of HT-B, a factor previously implicated in S-specific pollen rejection, disrupts rejection of N. plumbaginifolia pollen. Thus, S-specific pollen rejection and rejection of N. plumbaginifolia pollen are mechanistically distinct, because they require different non-S-RNase factors.

Genetic Modification of the Relationship between Parental Rejection and Adolescent Alcohol Use.

Stogner, John M; Gibson, Chris L

Parenting practices are associated with adolescents' alcohol consumption, however not all youth respond similarly to challenging family situations and harsh environments. This study examines the relationship between perceived parental rejection and adolescent alcohol use, and specifically evaluates whether youth who possess greater genetic sensitivity to their environment are more susceptible to negative parental relationships. Analyzing data from the National Longitudinal Study of Adolescent Health, we estimated a series of regression models predicting alcohol use during adolescence. A multiplicative interaction term between parental rejection and a genetic index was constructed to evaluate this potential gene-environment interaction. Results from logistic regression analyses show a statistically significant gene-environment interaction predicting alcohol use. The relationship between parental rejection and alcohol use was moderated by the genetic index, indicating that adolescents possessing more 'risk alleles' for five candidate genes were affected more by stressful parental relationships. Feelings of parental rejection appear to influence the alcohol use decisions of youth, but they do not do so equally for all. Higher scores on the constructed genetic sensitivity measure are related to increased susceptibility to negative parental relationships. © The Author 2016.

Background The extant literature demonstrates that children with autism spectrum disorder (ASD) often have difficulty interacting and socially connecting with typically developing classmates. However, some children with ASD have social outcomes that are consistent with their typically developing counterparts. Little is known about this subgroup of children with ASD. This study examined the stable (unlikely to change) and malleable (changeable) characteristics of socially successful children with ASD. Methods This study used baseline data from three intervention studies performed in public schools in the Southwestern United States. A total of 148 elementary-aged children with ASD in 130 classrooms in 47 public schools participated. Measures of playground peer engagement and social network salience (inclusion in informal peer groups) were obtained. Results The results demonstrated that a number of malleable factors significantly predicted playground peer engagement (class size, autism symptom severity, peer connections) and social network salience (autism symptom severity, peer connections, received friendships). In addition, age was the only stable factor that significantly predicted social network salience. Interestingly, two malleable (i.e., peer connections and received friendships) and no stable factors (i.e., age, IQ, sex) predicted overall social success (e.g., high playground peer engagement and social network salience) in children with ASD. Conclusions School-based interventions should address malleable factors such as the number of peer connections and received friendships that predict the best social outcomes for children with ASD.

Social rejection often increases aggression, but the neural mechanisms underlying this effect remain unclear. This experiment tested whether neural activity in the dorsal anterior cingulate cortex (dACC) and anterior insula in response to social rejection predicted greater subsequent aggression. Additionally, it tested whether executive functioning moderated this relationship. Participants completed a behavioral measure of executive functioning, experienced social rejection while undergoing functional magnetic resonance imaging and then completed a task in which they could aggress against a person who rejected them using noise blasts . We found that dACC activation and executive functioning interacted to predict aggression. Specifically, participants with low executive functioning showed a positive association between dACC activation and aggression, whereas individuals with high executive functioning showed a negative association. Similar results were found for the left anterior insula. These findings suggest that social pain can increase or decrease aggression, depending on an individual’s regulatory capability.

There is a substantial literature documenting pre-schoolers' racial awareness and affect from multiracial societies in North America and a fast-growing body of work from societies that are or were once more racially homogeneous. However, studies in Britain, a racially diverse society, on this developmental period have been curiously rare. This study examined racial awareness and affect of 125 White, Black, and Asian 3--to 5-year-olds in London. Children were tested on cognitive level, person description and classification, race labelling and matching, self-categorization and asked about their racial preference and rejection and inferences about their mothers' preference and rejection. Children were least likely to use race versus other categorical cues to spontaneously describe or classify others, even though the majority correctly sorted others by race labels, matched them to drawings, and categorized themselves by race. With age and increasing cognitive level, children described and categorized others by race more and improved in race matching. White children from age 4 preferred White peers and inferred that their mothers would prefer White children at age 5. Children's own preference and inference about mothers are related. Children did not show race-based rejection, but boys inferred that their mothers would prefer White children and reject Black children. The findings are discussed in relation to racial salience between contexts, previous research, and theories. ©2010 The British Psychological Society.

Health-related quality of life and peer relationships in adolescents with developmental coordination disorder and attention-deficit-hyperactivity disorder.

Health-related quality of life (HRQoL) and peer relationships were investigated in adolescents with developmental coordination disorder (DCD) and attention-deficit-hyperactivity disorder (ADHD). Adolescents with DCD (n=9), ADHD (n=9), DCD and ADHD (n=10), and typically developing adolescents (n=16) completed the following questionnaires: KIDSCREEN-52 Health-Related Quality of Life Questionnaire and Peer Relations Questionnaire for Children. Twenty-five participants took part in semi-structured interviews. Adolescents with DCD and ADHD had lower HRQoL on the mood and emotions, school environment, and financial resources scales of the KIDSCREEN-52 than adolescents in the DCD and typically developing groups (all p<0.05). On the Peer Relations Questionnaire for Children, the DCD and ADHD group reported significantly higher victimization compared with those in the typically developing (p=0.030) and DCD (p=0.010) groups. Qualitative interviews among young people with DCD and ADHD revealed feelings of marginalization and victimization. Descriptors such as 'misfits', 'oddballs', 'weird', and 'the rejects' were used to describe themselves. HRQoL and peer relationships are negatively affected in adolescents with DCD and ADHD. WHAT THIS PAPER ADDS?: Children with developmental coordination disorder (DCD) do not display poorer overall health-related quality of life (HRQoL) versus typically developing controls. Having DCD and attention-deficit-hyperactivity disorder (ADHD) was associated with poorer HRQoL. Adolescents with DCD and ADHD experience significantly higher levels of peer victimization than typically developing adolescents. HRQoL and peer relationships are significantly associated in adolescent respondents. © 2018 Mac Keith Press.

MDMA DECREASES THE EFFECTS OF SIMULATED SOCIAL REJECTION

2014-01-01

3-4-methylenedioxymethamphetamine (MDMA) increases self-reported positive social feelings and decreases the ability to detect social threat in faces, but its effects on experiences of social acceptance and rejection have not been determined. We examined how an acute dose of MDMA affects subjective and autonomic responses to simulated social acceptance and rejection. We predicted that MDMA would decrease subjective responses to rejection. On an exploratory basis, we also examined the effect of MDMA on respiratory sinus arrhythmia (RSA), a measure of parasympathetic cardiac control often thought to index social engagement and emotional regulation. Over three sessions, healthy adult volunteers with previous MDMA experience (N = 36) received capsules containing placebo, 0.75 or 1.5 mg/kg of MDMA under counter-balanced double-blind conditions. During expected peak drug effect, participants played two rounds of a virtual social simulation task called “Cyberball” during which they experienced acceptance in one round and rejection in the other. During the task we also obtained electrocardiograms (ECGs), from which we calculated RSA. After each round, participants answered questionnaires about their mood and self-esteem. As predicted, MDMA decreased the effect of simulated social rejection on self-reported mood and self-esteem and decreased perceived intensity of rejection, measured as the percent of ball tosses participants reported receiving. Consistent with its sympathomimetic properties, MDMA decreased RSA as compared to placebo. Our finding that MDMA decreases perceptions of rejection in simulated social situations extends previous results indicating that MDMA reduces perception of social threat in faces. Together these findings suggest a cognitive mechanism by which MDMA might produce pro-social behavior and feelings and how the drug might function as an adjunct to psychotherapy. These phenomena merit further study in non-simulated social environments. PMID:24316346

Friendships play a major role in cognitive, emotional and social development in middle childhood. We employed the online Cyberball social exclusion paradigm to understand the neural correlates of dyadic social exclusion among best friends assessed simultaneously. Each child played with their friend and an unfamiliar player. Event-related potentials (ERPs) were assessed via electroencephalogram during exclusion by friend and unfamiliar peer. Data were analyzed with hierarchical linear modeling to account for nesting of children within friendship dyads. Results showed that stranger rejection was associated with larger P2 and positive slow wave ERP responses compared to exclusion by a friend. Psychological distress differentially moderated the effects of friend and stranger exclusion such that children with greater psychological distress were observed to have larger neural responses (larger P2 and slow wave) to exclusion by a stranger compared to exclusion by a friend. Conversely, children with lower levels of psychological distress had larger neural responses for exclusion by a friend than by a stranger. Psychological distress within the dyad differentially predicted the P2 and slow wave response. Findings highlight the prominent, but differential role of individual and dyadic psychological distress levels in moderating responses to social exclusion in middle childhood. PMID:27330184

Aggression and social withdrawal as viewed by children's peers: conceptual issues in assessment and implications for intervention.

PubMed Central

Younger, A J; Schneider, B H; Daniels, T

1991-01-01

Children's peer assessments of aggressive and withdrawn behavior are fundamentally related to developmental changes in their understanding of others. This article synthesizes research relevant to the thesis that peer assessments are dependent on children's ability both to recall the previous behavior of their peers and to predict their likely future behavior. Social schema theory, borrowed from adult social psychology, is highly relevant to such recall and prediction. Age differences, affective biases, and gender roles may color children's assessments of their peers' social behavior. Such influences should be taken into account when conceptualizing interventions aimed at enhancing children's peer status, and in measuring the success of these interventions. PMID:1958647

Determinants of Prosocial Behavior in Included Versus Excluded Contexts

Cuadrado, Esther; Tabernero, Carmen; Steinel, Wolfgang

2016-01-01

Prosocial behavior (PSB) is increasingly becoming necessary as more and more individuals experience exclusion. In this context it is important to understand the motivational determinants of PSB. Here we report two experiments which analyzed the influence of dispositional (prosocialness; rejection sensitivity) and motivational variables (prosocial self-efficacy; prosocial collective efficacy; trust; anger; social affiliation motivation) on PSB under neutral contexts (Study 1), and once under inclusion or exclusion conditions (Study 2). Both studies provided evidence for the predicted mediation of PSB. Results in both neutral and inclusion and exclusion conditions supported our predictive model of PSB. In the model dispositional variables predicted motivational variables, which in turn predicted PSB. We showed that the investigated variables predicted PSB; this suggests that to promote PSB one could (1) foster prosocialness, prosocial self and collective efficacy, trust in others and affiliation motivation and (2) try to reduce negative feelings and the tendency to dread rejection in an attempt to reduce the negative impact that these variables have on PSB. Moreover, the few differences that emerged in the model between the inclusion and exclusion contexts suggested that in interventions with excluded individuals special care emphasis should be placed on addressing rejection sensitivity and lack of trust.

Rejection as a call to arms: inter-racial hostility and support for political action as outcomes of race-based rejection in majority and minority groups.

2012-03-01

Both majority and minority group members fear race-based rejection, and respond by disparaging the groups that they expect will reject them. It is not clear, however, how this process differs in minority and majority groups. Using large representative samples of White (N= 4,618) and Māori (N= 1,163) New Zealanders, we found that perceptions of race-based rejection predicted outgroup negativity in both groups, but in different ways and for different reasons. For White (but not Māori) New Zealanders, increased intergroup anxiety partially mediated the relationship between cognitions of rejection and outgroup negativity. Māori who expected to be rejected on the basis of their race reported increased ethnic identification and, in part through this, increased support for political action benefiting their own group. This finding supports collective-action models of social change in historically disadvantaged minority groups. © 2011 The British Psychological Society.

Social knowledge in children with language impairments: examination of strategies, predicted consequences, and goals in peer conflict situations.

Timler, Geralyn R

2008-09-01

This study investigated social knowledge in school-age children, aged 8-12 years, with and without language impairment (LI and TD groups). A hypothetical peer conflict task was administered to examine the relationship among prosocial responses and parent/teacher ratings of children's social behaviours. Stimuli included 12 hypothetical peer conflict vignettes presented in an open-ended and forced choice condition. The LI group generated (open-ended) and selected (forced choice) fewer prosocial strategies. When asked to predict a friend's reaction to a selected conflict resolution strategy, the LI group predicted fewer positive consequences; however, the proportion of prosocial strategies followed by prediction of a positive peer consequence was similar across groups. Both groups identified more self-interest than relationship goals as the rationale for selected strategies. In the LI group, teacher ratings of children's social skills and problems in peer provocation situations were associated with selection of prosocial strategies. Implications for clinical service providers are discussed.

2012-04-01

The relations between young children's mutual (reciprocated) and overall positive emotion (PE) with same- and other-gender peers and their social adjustment were explored. Children's PE and peers' PE were observed across the preschool year during peer interactions (N = 166; 46% girls; M age = 52 months). Results revealed that girls and boys had similar frequencies of overall PE and mutual PE when interacting with same-gender peers, but girls were marginally higher compared with boys in overall and mutual PE when interacting with other-gender peers. Girls and boys did not have greater rates of either type of PE after controlling for gender segregation during same- or other-gender interactions. Using structural equation modeling, children's mutual PE, regardless of their gender, positively predicted indicators of positive adjustment (e.g., prosocial behavior, cooperation) and negatively predicted indicators of negative adjustment (e.g., hyperactivity, disruption, exclusion by peers). Children's overall PE did not predict either type of adjustment. Findings support the importance of mutual PE for children's development.

This study evaluated direct relations of both kindergarteners' (N = 301) naturalistically observed emotion in 2 different school contexts and early kindergarten verbal competence to academic adjustment (i.e., standardized measures of academic achievement, teacher-reported academic skills, teacher-reported and observed school engagement) and if these relations were mediated by teacher-reported conflict with students and by peer acceptance. When controlling for verbal competence, positive emotions expressed in the classroom context positively directly predicted academic skills, whereas positive emotions expressed outside class (lunch/recess) negatively predicted academic skills. Negative emotions observed in the classroom context and during lunch/recess negatively predicted academic achievement. Positive emotions observed in both contexts indirectly predicted higher school engagement through its positive relation to peer acceptance; positive emotions expressed in lunch and recess indirectly predicted higher school engagement via lower teacher-student conflict. Negative emotions observed in both contexts also indirectly predicted lower school engagement via higher teacher-student conflict. Furthermore, verbal competence indirectly predicted higher academic adjustment via lower teacher-student conflict. Moreover, verbal competence moderated the association between peer acceptance (but not teacher-student conflict) and academic adjustment. Because verbal competence moderated the associations from peer competence, positive emotions in both contexts indirectly predicted higher academic adjustment via higher peer acceptance primarily for children with low, but not high, initial verbal competence.

Objectives To assess whether reports from reviewers recommended by authors show a bias in quality and recommendation for editorial decision, compared with reviewers suggested by other parties, and whether reviewer reports for journals operating on open or single-blind peer review models differ with regard to report quality and reviewer recommendations. Design Retrospective analysis of the quality of reviewer reports using an established Review Quality Instrument, and analysis of reviewer recommendations and author satisfaction surveys. Setting BioMed Central biology and medical journals. BMC Infectious Diseases and BMC Microbiology are similar in size, rejection rates, impact factors and editorial processes, but the former uses open peer review while the latter uses single-blind peer review. The Journal of Inflammation has operated under both peer review models. Sample Two hundred reviewer reports submitted to BMC Infectious Diseases, 200 reviewer reports submitted to BMC Microbiology and 400 reviewer reports submitted to the Journal of Inflammation. Results For each journal, author-suggested reviewers provided reports of comparable quality to non-author-suggested reviewers, but were significantly more likely to recommend acceptance, irrespective of the peer review model (p<0.0001 for BMC Infectious Diseases, BMC Microbiology and the Journal of Inflammation). For BMC Infectious Diseases, the overall quality of reviewer reports measured by the Review Quality Instrument was 5% higher than for BMC Microbiology (p=0.042). For the Journal of Inflammation, the quality of reports was the same irrespective of the peer review model used. Conclusions Reviewers suggested by authors provide reports of comparable quality to non-author-suggested reviewers, but are significantly more likely to recommend acceptance. Open peer review reports for BMC Infectious Diseases were of higher quality than single-blind reports for BMC Microbiology. There was no difference in quality of peer review in the Journal of Inflammation under open peer review compared with single blind. PMID:26423855

Currently, acute allograft rejection can only be detected reliably by deterioration of graft function confirmed by allograft biopsy. A huge drawback of this method of diagnosis is that substantial organ damage has already taken place at the time that rejection is diagnosed. Discovering and validating noninvasive biomarkers that predict acute rejection, and chronic allograft dysfunction, is of great importance. Many studies have investigated changes in the peripheral blood in an attempt to find biomarkers that reflect changes in the graft directly or indirectly. Herein, we will review the promises and limitations of the peripheral blood biomarkers that have been described in the literature so far.

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

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.

Paternal psychological control demonstrated the same moderating effect for girls; for boys, however, high levels of paternal control predicted risky sex regardless of peer attitudes. Results are consistent with the theory that peer influences do not replace parental influences with regard to adolescent sexual behavior; rather, parental practices continue to serve an important role either directly forecasting sexual behavior or moderating the link between peer attitudes and sexual behavior.

The ethics of peer and editorial requests for self-citation of their work and journal.

PubMed

Teixeira da Silva, Jaime A

2017-04-01

Peer reviewers are expected to be experts in a field of study and should be versed with the pertinent literature related with the manuscript they are reviewing. Editors might not necessarily be experts in a particular field, but they have the responsibility of overseeing the requests made by peers, and assessing whether these are ethically appropriate, or not. Thus, requests by peers to cite unrelated literature, which may or may not be their own literature, could be unethical, especially if the objective is to improve their own citations or to boost the citations of the journal for which they are reviewing. In contrast, requests to cite pertinent work that is in fact missing from the paper's literature, even if it may be the reviewer or editor's work, or from the same journal, is acceptable. Editors ultimately approve the requests and suggestions made by reviewers, so inappropriate suggestions made by peer reviewers are the responsibility of the editor and journal. There needs to be a bias-free mechanism in place that offers protection to authors who wish to complain, and consequences for editors who do not conduct an impartial decision. Authors have the right to challenge such suggestions, but may face unfair retaliation in the form of a rejection if they resist making changes that they perceive as being inappropriate.

The Neural Basis of Recollection Rejection: Increases in Hippocampal-Prefrontal Connectivity in the Absence of a Shared Recall-to-Reject and Target Recollection Network.

PubMed

Bowman, Caitlin R; Dennis, Nancy A

2016-08-01

Recollection rejection or "recall-to-reject" is a mechanism that has been posited to help maintain accurate memory by preventing the occurrence of false memories. Recollection rejection occurs when the presentation of a new item during recognition triggers recall of an associated target, a mismatch in features between the new and old items is registered, and the lure is correctly rejected. Critically, this characterization of recollection rejection involves a recall signal that is conceptually similar to recollection as elicited by a target. However, previous neuroimaging studies have not evaluated the extent to which recollection rejection and target recollection rely on a common neural signal but have instead focused on recollection rejection as a postretrieval monitoring process. This study utilized a false memory paradigm in conjunction with an adapted remember-know-new response paradigm that separated "new" responses based on recollection rejection from those that were based on a lack of familiarity with the item. This procedure allowed for parallel recollection rejection and target recollection contrasts to be computed. Results revealed that, contrary to predictions from theoretical and behavioral literature, there was virtually no evidence of a common retrieval mechanism supporting recollection rejection and target recollection. Instead of the typical target recollection network, recollection rejection recruited a network of lateral prefrontal and bilateral parietal regions that is consistent with the retrieval monitoring network identified in previous neuroimaging studies of recollection rejection. However, a functional connectivity analysis revealed a component of the frontoparietal rejection network that showed increased coupling with the right hippocampus during recollection rejection responses. As such, we demonstrate a possible link between PFC monitoring network and basic retrieval mechanisms within the hippocampus that was not revealed with univariate analyses alone.

Gender, status, and psychiatric labels.

PubMed

Kroska, Amy; Harkness, Sarah K; Brown, Ryan P; Thomas, Lauren S

2015-11-01

We examine a key modified labeling theory proposition-that a psychiatric label increases vulnerability to competence-based criticism and rejection-within task- and collectively oriented dyads comprised of same-sex individuals with equivalent education. Drawing on empirical work that approximates these conditions, we expect the proposition to hold only among men. We also expect education, operationalized with college class standing, to moderate the effects of gender by reducing men's and increasing women's criticism and rejection. But, we also expect the effect of education to weaken when men work with a psychiatric patient. As predicted, men reject suggestions from teammates with a psychiatric history more frequently than they reject suggestions from other teammates, while women's resistance to influence is unaffected by their teammate's psychiatric status. Men also rate psychiatric patient teammates as less powerful but no lower in status than other teammates, while women's teammate assessments are unaffected by their teammate's psychiatric status. Also as predicted, education reduces men's resistance to influence when their teammate has no psychiatric history. Education also increases men's ratings of their teammate's power, as predicted, but has no effect on women's resistance to influence or teammate ratings. We discuss the implications of these findings for the modified labeling theory of mental illness and status characteristics theory. Copyright © 2015 Elsevier Inc. All rights reserved.

Childhood peer reputation as a predictor of competence and symptoms 10 years later.

Gest, Scott D; Sesma, Arturo; Masten, Ann S; Tellegen, Auke

2006-08-01

This study examined the differential developmental significance of multiple domains of peer reputation in childhood for current and future competence and symptoms. Participants were 205 children from a normative school cohort who completed assessments in grades 3-6 and then again 10 years later. Through re-analysis of original data from the Revised Class Play (RCP; N=612), new narrow-band subscales were examined as distinct correlates and predictors of competence in age-relevant developmental tasks and psychological well being as indexed by internalizing symptoms. Findings support the differentiation of peer exclusion, withdrawal, and sadness within the broad sensitive-isolated domain of reputation, as well as the distinctive meaning of reputations for Popularity-Leadership and Prosocial Behavior within the broad Sociable-Leader domain. When the Sensitive-Isolated predictors were considered, academic and job competence at the 10-year follow-up were predicted uniquely and negatively by peer exclusion, problems in the social and romantic domains were predicted distinctively by withdrawal from peers, and internalizing symptoms were uniquely predicted by childhood reputation as Sad-Sensitive. When the Sociable-Leader predictors were considered, academic and (for ethnic minority youth) job success was predicted by a Prosocial reputation, social success was forecasted by Popularity-Leadership, and romantic competence was predicted positively by Popularity-Leadership and negatively by Prosocial reputation. Negative academic and job outcomes were also predicted by a childhood reputation as Aggressive-Disruptive. Results are discussed in relation to conceptualizing and measuring peer social competence and its relation to later adaptation.

Violent peer influence: The roles of self-esteem and psychopathic traits.

PubMed

Van Zalk, Maarten Herman Walter; Van Zalk, Nejra

2015-11-01

Evidence for the risks of psychopathic personality traits for adolescent antisocial behavior are well documented in the literature. Little is known, however, about who the peers of adolescents with these traits are and to what extent they influence one another. In the current study, three dimensions of psychopathic traits were distinguished: grandiose-manipulative traits, callous-unemotional traits, and impulsive-irresponsible traits. A dynamic social network approach was used with three waves of longitudinal data from 1,772 adolescents (51.1% girls, M age = 13.03 at first measurement). Results showed that adolescents with grandiose-manipulative and callous-unemotional traits formed peer relationships with adolescents who had low self-esteem. Furthermore, peers' violence predicted stronger increases in violence for adolescents with low self-esteem than for other adolescents, and peers' violence predicted stronger increases in adolescent violence for peers with high psychopathic traits than for other peers. Thus, findings indicate that adolescents with low self-esteem are vulnerable to deviant peer influence from peers with psychopathic traits.

Time with Peers from Middle Childhood to Late Adolescence: Developmental Course and Adjustment Correlates

Lam, Chun Bun; McHale, Susan M.; Crouter, Ann C.

2014-01-01

This study examined the developmental course and adjustment correlates of time with peers from age 8 to 18. On 7 occasions over 8 years, the two eldest siblings from 201 European American, working- and middle-class families provided questionnaire and/or phone diary data. Multilevel models revealed that girls’ time with mixed/opposite-sex peers increased beginning in middle childhood, but boys’ time increased beginning in early adolescence. For both girls and boys, time with same-sex peers peaked in mid-adolescence. At the within-person level, unsupervised time with mixed/opposite-sex peers longitudinally predicted problem behaviors and depressive symptoms, and supervised time with mixed/opposite-sex peers longitudinally predicted better school performance. Findings highlight the importance of social context in understanding peer involvement and its implications for youth development. PMID:24673293

A peer review process as part of the implementation of clinical pathways in radiation oncology: Does it improve compliance?

PubMed

Gebhardt, Brian J; Heron, Dwight E; Beriwal, Sushil

Clinical pathways are patient management plans that standardize evidence-based practices to ensure high-quality and cost-effective medical care. Implementation of a pathway is a collaborative process in our network, requiring the active involvement of physicians. This approach promotes acceptance of pathway recommendations, although a peer review process is necessary to ensure compliance and to capture and approve off-pathway selections. We investigated the peer review process and factors associated with time to completion of peer review. Our cancer center implemented radiation oncology pathways for every disease site throughout a large, integrated network. Recommendations are written based upon national guidelines, published literature, and institutional experience with evidence evaluated hierarchically in order of efficacy, toxicity, and then cost. Physicians enter decisions into an online, menu-driven decision support tool that integrates with medical records. Data were collected from the support tool and included the rate of on- and off-pathway selections, peer review decisions performed by disease site directors, and time to complete peer review. A total of 6965 treatment decisions were entered in 2015, and 605 (8.7%) were made off-pathway and were subject to peer review. The median time to peer review decision was 2 days (interquartile range, 0.2-6.8). Factors associated with time to peer review decision >48 hours on univariate analysis include disease site (P < .0001) with a trend toward significance (P = .066) for radiation therapy modality. There was no difference between recurrent and non-recurrent disease (P = .267). Multivariable analysis revealed disease site was associated with time to peer review (P < .001), with lymphoma and skin/sarcoma most strongly influencing decision time >48 hours. Clinical pathways are an integral tool for standardizing evidence-based care throughout our large, integrated network, with 91.3% of all treatment decisions being made as per pathway. The peer review process was feasible, with <1% selections ultimately rejected, suggesting that awareness of peer review of treatment decisions encourages compliance with clinical pathway recommendations.

Parent and Peer Links to Trajectories of Anxious Withdrawal From Grades 5 to 8

Booth-LaForce, Cathryn; Oh, Wonjung; Kennedy, Amy E.; Rubin, Kenneth H.; Rose-Krasnor, Linda; Laursen, Brett

2013-01-01

Individual differences in trajectories of anxious withdrawal were examined from Grades 5 to 8 across the transition to middle school in a community sample (N = 283), using General Growth Mixture Modeling. Three distinct pathways of anxious withdrawal were identified: low-stable (78%), high-decreasing (12%), and high-increasing (10%). In Grade 6, relative to the low-stable class, greater peer exclusion and more free time spent with mother predicted membership in the high-decreasing class; higher peer exclusion predicted membership in the high-increasing class. Within the high-increasing class, the growth of anxious withdrawal was predicted by lower parental autonomy-granting, less free time with mother, both nurturing and restrictive parenting, and greater peer exclusion. Results highlight the role of both parent–child relationship and peer difficulties in increasing the adjustment risk among youth who are anxiously withdrawn prior to the middle-school transition.

2012-01-01

Embedded in achievement goal theory (Ames, 1992; Meece, Anderman, & Anderman, 2006), this study examined how perceptions of coach and peer motivational climate in youth sport predicted moral attitudes, emotional well-being, and indices of behavioral investment in a sample of British adolescents competing in regional leagues. We adopted a longitudinal perspective, taking measures at the middle and the end of a sport season, as well as at the beginning of the following season. Multilevel modeling analyses showed that perceptions of task-involving peer and coach climates were predictive of more adaptive outcomes than were perceptions of ego-involving peer and coach climates. Predictive effects differed as a function of time and outcome variable under investigation. The results indicate the importance of considering peer influence in addition to coach influence when examining motivational climate in youth sport.

Family and Peer Predictors of Substance Use From Early Adolescence to Early Adulthood: An 11-Year Prospective Analysis

PubMed Central

Van Ryzin, Mark J.; Fosco, Gregory M.; Dishion, Thomas J.

2012-01-01

The focus of this study was social (i.e., family and peer) influences on substance use from early adolescence to early adulthood. A large, ethnically diverse sample of early adolescents (N = 998) was followed from age 12 to age 23. We tested direct and indirect effects of parental monitoring, family relationship quality, and association with deviant peers on change in substance use across time. Outcomes for tobacco, alcohol, and marijuana use were analyzed as separate pathways within the same overall model. The results suggest that a significant shift in the nature of family influence occurred across adolescence and into early adulthood, but deviant peer influence was relatively consistent across this period. Specifically, parental monitoring and deviant peer association were predictive of substance use in early adolescence, but family relationship quality was a significant predictor across the transition to high school and generally continued to predict use into later adolescence, as did association with deviant peers. Deviant peers were the only significant predictor in early adulthood. Our results also suggested that parental monitoring and family relationship quality indirectly predicted later substance use by way of deviant peers, implying that an important aspect of the family context is its influence on choice of friends and peer group composition. Implications for family-based prevention and intervention are discussed. PMID:22958864

An Ecological Analysis of the Effects of Deviant Peer Clustering on Sexual Promiscuity, Problem Behavior, and Childbearing from Early Adolescence to Adulthood: An Enhancement of the Life History Framework

Dishion, Thomas J.; Ha, Thao; Véronneau, Marie-Hélène

2012-01-01

This study proposes the inclusion of peer relationships in a life history perspective on adolescent problem behavior. Longitudinal analyses were used to examine deviant peer clustering as the mediating link between attenuated family ties, peer marginalization, and social disadvantage in early adolescence and sexual promiscuity in middle adolescence and childbearing by early adulthood. Specifically, 998 youth and their families were assessed at age 11 years and periodically through age 24 years. Structural equation modeling revealed that the peer-enhanced life history model provided a good fit to the longitudinal data, with deviant peer clustering strongly predicting adolescent sexual promiscuity and other correlated problem behaviors. Sexual promiscuity, as expected, also strongly predicted the number of children by age 22–24 years. Consistent with a life history perspective, family social disadvantage directly predicted deviant peer clustering and number of children in early adulthood, controlling for all other variables in the model. These data suggest that deviant peer clustering is a core dimension of a fast life history strategy, with strong links to sexual activity and childbearing. The implications of these findings are discussed with respect to the need to integrate an evolutionary-based model of self-organized peer groups in developmental and intervention science.

Convergence of Internet and TV: The Commercial Viability of P2P Content Delivery

NASA Astrophysics Data System (ADS)

de Boever, Jorn

The popularity of (illegal) P2P (peer-to-peer) file sharing has a disruptive impact on Internet traffic and business models of content providers. In addition, several studies have found an increasing demand for bandwidth consuming content, such as video, on the Internet. Although P2P systems have been put forward as a scalable and inexpensive model to deliver such content, there has been relatively little economic analysis of the potentials and obstacles of P2P systems as a legal and commercial content distribution model. Many content providers encounter uncertainties regarding the adoption or rejection of P2P networks to spread content over the Internet. The recent launch of several commercial, legal P2P content distribution platforms increases the importance of an integrated analysis of the Strengths, Weaknesses, Opportunities and Threats (SWOT).

Developmental Trajectories of Chinese Adolescents' Relational Aggression: Associations With Changes in Social-Psychological Adjustment.

This study investigated the development of relational aggression (RA) in a sample of Chinese youth (N = 2,274, 52% boys) from fourth (M age  = 10.27 years) to ninth grade. Using latent class growth analysis, four trajectories were identified for both peer- and teacher-rated RA: a no aggression trajectory, a low-increasing trajectory, a moderate-decreasing trajectory, and a chronically high trajectory. Chronically high RA showed a chronicity effect on adolescent peer acceptance, rejection, and rule-breaking behaviors. Adolescents showed worse adjustment as RA increased, but they did not necessarily evidence significant improvement in adjustment even if their RA decreased. Findings reveal the maladaptive nature of RA and highlight the importance of considering cultural context in understanding RA. © 2018 Society for Research in Child Development.

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

Context-Aware Reviewer Assignment for Trust Enhanced Peer Review

2015-01-01

Reviewer assignment is critical to peer review systems, such as peer-reviewed research conferences or peer-reviewed funding applications, and its effectiveness is a deep concern of all academics. However, there are some problems in existing peer review systems during reviewer assignment. For example, some of the reviewers are much more stringent than others, leading to an unfair final decision, i.e., some submissions (i.e., papers or applications) with better quality are rejected. In this paper, we propose a context-aware reviewer assignment for trust enhanced peer review. More specifically, in our approach, we first consider the research area specific expertise of reviewers, and the institution relevance and co-authorship between reviewers and authors, so that reviewers with the right expertise are assigned to the corresponding submissions without potential conflict of interest. In addition, we propose a novel cross-assignment paradigm, and reviewers are cross-assigned in order to avoid assigning a group of stringent reviewers or a group of lenient reviewers to the same submission. More importantly, on top of them, we propose an academic CONtext-aware expertise relevanCe oriEnted Reviewer cross-assignmenT approach (CONCERT), which aims to effectively estimate the “true” ratings of submissions based on the ratings from all reviewers, even though no prior knowledge exists about the distribution of stringent reviewers and lenient reviewers. The experiments illustrate that compared with existing approaches, our proposed CONCERT approach can less likely assign more than one stringent reviewers or lenient reviewers to a submission simultaneously and significantly reduce the influence of ratings from stringent reviewers and lenient reviewers, leading to trust enhanced peer review and selection, no matter what kind of distributions of stringent reviewers and lenient reviewers are.

2009-11-01

Competing predictions about the effect of social exclusion were tested by meta-analyzing findings from studies of interpersonal rejection, ostracism, and similar procedures. Rejection appears to cause a significant shift toward a more negative emotional state. Typically, however, the result was an emotionally neutral state marked by low levels of both positive and negative affect. Acceptance caused a slight increase in positive mood and a moderate increase in self-esteem. Self-esteem among rejected persons was no different from neutral controls. These findings are discussed in terms of belongingness motivation, sociometer theory, affective numbing, and self-esteem defenses.

Private Information and Insurance Rejections

PubMed Central

Hendren, Nathaniel

2013-01-01

Across a wide set of non-group insurance markets, applicants are rejected based on observable, often high-risk, characteristics. This paper argues that private information, held by the potential applicant pool, explains rejections. I formulate this argument by developing and testing a model in which agents may have private information about their risk. I first derive a new no-trade result that theoretically explains how private information could cause rejections. I then develop a new empirical methodology to test whether this no-trade condition can explain rejections. The methodology uses subjective probability elicitations as noisy measures of agents beliefs. I apply this approach to three non-group markets: long-term care, disability, and life insurance. Consistent with the predictions of the theory, in all three settings I find significant amounts of private information held by those who would be rejected; I find generally more private information for those who would be rejected relative to those who can purchase insurance; and I show it is enough private information to explain a complete absence of trade for those who would be rejected. The results suggest private information prevents the existence of large segments of these three major insurance markets. PMID:24187381

Roles of temperamental arousal and gender-segregated play in young children's social adjustment.

Fabes, R A; Shepard, S A; Guthrie, I K; Martin, C L

1997-07-01

The hypothesis that gender differences in children's adjustment is partially influenced by differences in temperament and interactions with same-sex peers was examined. Fifty-seven predominantly White, middle-class preschoolers (29 boys and 28 girls, M age = 54.5 months) participated. Measures were taken of children's arousability, problem behaviors, and tendencies to play with same-sex peers. A semester later, children's peer status was assessed. Analyses revealed that arousability and same-sex peer play interacted to predict problem behaviors. For boys high in arousability, play with same-sex peers increased problem behaviors. In contrast, arousable girls who played with other girls were relatively unlikely to show problem behaviors. Moreover, the interaction of arousability and same-sex peer play predicted boys' (but not girls') peer status, and this relation was partially mediated by problem behaviors. The role of gender-related processes is discussed.

Experimental shifts in intraclutch egg color variation do not affect egg rejection in a host of a non-egg-mimetic avian brood parasite.

PubMed

Croston, Rebecca; Hauber, Mark E

2015-01-01

Avian brood parasites lay their eggs in the nests of other birds, and impose the costs associated with rearing parasitic young onto these hosts. Many hosts of brood parasites defend against parasitism by removing foreign eggs from the nest. In systems where parasitic eggs mimic host eggs in coloration and patterning, extensive intraclutch variation in egg appearances may impair the host's ability to recognize and reject parasitic eggs, but experimental investigation of this effect has produced conflicting results. The cognitive mechanism by which hosts recognize parasitic eggs may vary across brood parasite hosts, and this may explain variation in experimental outcome across studies investigating egg rejection in hosts of egg-mimicking brood parasites. In contrast, for hosts of non-egg-mimetic parasites, intraclutch egg color variation is not predicted to co-vary with foreign egg rejection, irrespective of cognitive mechanism. Here we tested for effects of intraclutch egg color variation in a host of nonmimetic brood parasite by manipulating egg color in American robins (Turdus migratorius), hosts of brown-headed cowbirds (Molothrus ater). We recorded robins' behavioral responses to simulated cowbird parasitism in nests where color variation was artificially enhanced or reduced. We also quantified egg color variation within and between unmanipulated robin clutches as perceived by robins themselves using spectrophotometric measures and avian visual modeling. In unmanipulated nests, egg color varied more between than within robin clutches. As predicted, however, manipulation of color variation did not affect rejection rates. Overall, our results best support the scenario wherein egg rejection is the outcome of selective pressure by a nonmimetic brood parasite, because robins are efficient rejecters of foreign eggs, irrespective of the color variation within their own clutch.

Rejection, cardiac allograft vasculopathy (CAV), and infection are significant causes of mortality in heart transplantation recipients. Assessing the immune status of a particular patient remains challenging. Although endomyocardial biopsy (EMB) and angiography are effective for the identification of rejection and CAV, respectively, these are expensive, invasive, and may have numerous complications. The aim of this study was to evaluate the immune function and assess its utility in predicting rejection, CAV, and infection in heart transplantation recipients. We prospectively obtained samples at the time of routine EMB and when clinically indicated for measurement of the ImmuKnow assay (IM), 12 cytokines and soluble CD30 (sCD30). EMB specimens were evaluated for acute cellular rejection, and antibody-mediated rejection (AMR). CAV was diagnosed by the development of angiographic coronary artery disease. Infectious episodes occurring during the next 30 days after testing were identified by the presence of positive bacterial or fungal cultures and/or viremia that prompted treatment with antimicrobials. We collected 162 samples from 56 cardiac transplant recipients. There were 31 infection episodes, 7 AMR, and 4 CAV cases. The average IM value was significantly lower during infection, (P = .04). Soluble CD30 concentrations showed significantly positive correlation with infection episodes, (P = .001). Significant positive correlation was observed between interleukin-5(IL-5) and AMR episodes (P = .008). Tumor necrosis factor-α and IL-8 showed significant positive correlation with CAV (P = .001). Immune function monitoring appears promising in predicting rejection, CAV, and infection in cardiac transplantation recipients. This approach may help in more individualized immunosuppression and it may also minimize unnecessary EMBs and cardiac angiographies. Published by Elsevier Inc.

Does presentation at the Registrars' Papers Day predict future publication?

PubMed

Wong, Shing W; Crowe, Philip J

2006-06-01

There are research requirements for trainees to be eligible to present for their final examinations (Fellowship of Royal Australasian College of Surgeons, FRACS). One option is the presentation of a paper or poster at a meeting of which abstracts are subject to review and selection. This includes presentation at the annual Registrars' Papers Day (RPD) in New South Wales. There has been some debate surrounding whether research requirements are fulfilled by presentation at such meetings. Publication in a peer-reviewed journal should be the ultimate aim. A high publication rate will validate the quality of the meeting. All abstracts submitted to the RPD in 1998 and 1999 were analysed. A Medline search was performed in 2005 to identify publication of these presentations in a peer-reviewed journal. Variables of the study that were potentially predictive of subsequent publication were analysed. This included type of presentation, surgical specialty, clinical or laboratory-based study, study design (prospective or retrospective) and sample size. Chi-squared test with Yates' continuity correction was used to compare two independent proportions and significance was set at P < 0.05. The publication rates were: oral presentations 50% (17/34), poster presentations 39% (9/23) and rejected presentations 20% (2/10). The mean and median time to publication was 23.8 and 21.0 months. Prospective design was the only variable identified to have a statistically significant effect on the publication rate (P < 0.002). The most common publishing journal was the Australian and New Zealand Journal of Surgery (12 of 26). Overall consistency (author and study sample consistency) from presentation to publication was 32%. The overall 46% publication rate of this state-based trainees-organized meeting compares favourably with international meetings. The research requirement of the Royal Australasian College of Surgeons (RACS), which includes presentation at the RPD in New South Wales, produces good quality papers for publication.

In mainstream education, positive relationships with teachers and peers have been found to positively influence children's behavioral development. However, high levels of classroom behavior problems may hinder the formation of such positive relationships. Therefore, findings from mainstream education cannot be generalized to special education. The present study investigated the developmental links between disobedience and positive as well as negative relationships with teachers and peers among boys in restrictive special educational settings. At three assessment waves across one school year, teacher-reports of teacher-child closeness and conflict, and peer-reports of peer acceptance, rejection and disobedience were collected among 340 boys (mean age = 10.1 years, SD = 1.58, range = 5-13) with psychiatric disorders receiving special education. Autoregressive cross-lagged models were fitted to explore the nature of these developmental links. The impact of boys' age was examined using multiple group analyses. Findings supported the importance of teacher-child conflict, but not closeness, and positive and negative peer relationships for the development of boys' disobedience, with a stronger effect of negative than positive relationships. However, teacher-child and peer relationships were not longitudinally related and the effect of boys' age was minimal. This study extends prior research by suggesting that, despite differences in educational setting and severity of behavior problems between children in mainstream and special education, reducing negative classroom interactional patterns is most important in preventing the development of problematic classroom behavior in boys with severe social-emotional and behavioral difficulties.

A Dyadic Perspective on Speech Accommodation and Social Connection: Both Partners' Rejection Sensitivity Matters.

Findings from confederate paradigms predict that mimicry is an adaptive route to social connection for rejection-sensitive individuals (Lakin, Chartrand, & Arkin, 2008). However, dyadic perspectives predict that whether mimicry leads to perceived connection depends on the rejection sensitivity (RS) of both partners in an interaction. We investigated these predictions in 50 college women who completed a dyadic cooperative task in which members were matched or mismatched in being dispositionally high or low in RS. We used a psycholinguistics paradigm to assess, through independent listeners' judgments (N = 162), how much interacting individuals accommodate phonetic aspects of their speech toward each other. Results confirmed predictions from confederate paradigms in matched RS dyads. However, mismatched dyads showed an asymmetry in levels of accommodation and perceived connection: Those high in RS accommodated more than their low-RS partner but emerged feeling less connected. Mediational analyses indicated that low-RS individuals' nonaccommodation in mismatched dyads helped explain their high-RS partners' relatively low perceived connection to them. Establishing whether mimicry is an adaptive route to social connection requires analyzing mimicry as a dyadic process influenced by the needs of each dyad member. © 2014 Wiley Periodicals, Inc.

The aim of the study was to explore the typology of adolescents with immigrant background based on the orientations of acculturation and to estimate the psychosocial adaptation of the various subtypes. A sample of 228 French high school students with an immigrant background completed a questionnaire assessing acculturation orientations (Immigrant Acculturation Scale; Barrette et al., 2004), antisocial behaviors, depressive symptoms and self-esteem. Cluster analysis based on acculturation orientations was performed using the k-means method. Cluster analysis produced four distinct acculturation profiles: bicultural (31%), separated (28%), marginalized (21%), and assimilated-individualistic (20%). Adolescents in the separated and marginalized clusters, both characterized by rejection of the host culture, reported higher levels of antisocial behavior. Depressive symptoms and self-esteem did not differ between clusters. Several hypotheses may explain the association between separation and delinquency. First, separation and rejection of the host culture may lead to rebellious behavior such as delinquency. Conversely, delinquent behavior may provoke rejection or discrimination by peers or school, or legal sanctions that induce a reciprocal process of rejection of the host culture and separation. The relationship between separation and antisocial behavior may be bidirectional, each one reinforcing the other, resulting in a negative spiral. This study confirms the interest of the study of the orientations of acculturation in the understanding of the antisocial behavior of adolescents with immigrant background.

Research on the role of sex-related Internet use in adolescents’ sexual development has often isolated the Internet and online behaviors from other, offline influencing factors in adolescents’ lives, such as processes in the peer domain. The aim of this study was to test an integrative model explaining how receptive (i.e., use of sexually explicit Internet material [SEIM]) and interactive (i.e., use of social networking sites [SNS]) sex-related online behaviors interrelate with perceived peer norms in predicting adolescents’ experience with sexual behavior. Structural equation modeling on longitudinal data from 1,132 Dutch adolescents (Mage T1 = 13.95; range 11-17; 52.7% boys) demonstrated concurrent, direct, and indirect effects between sex-related online behaviors, perceived peer norms, and experience with sexual behavior. SEIM use (among boys) and SNS use (among boys and girls) predicted increases in adolescents’ perceptions of peer approval of sexual behavior and/or in their estimates of the numbers of sexually active peers. These perceptions, in turn, predicted increases in adolescents’ level of experience with sexual behavior at the end of the study. Boys’ SNS use also directly predicted increased levels of experience with sexual behavior. These findings highlight the need for multisystemic research and intervention development to promote adolescents’ sexual health. PMID:26086606

To achieve robust and stable legged locomotion in uneven terrain, animals must effectively coordinate limb swing and stance phases, which involve distinct yet coupled dynamics. Recent theoretical studies have highlighted the critical influence of swing-leg trajectory on stability, disturbance rejection, leg loading and economy of walking and running. Yet, simulations suggest that not all these factors can be simultaneously optimized. A potential trade-off arises between the optimal swing-leg trajectory for disturbance rejection (to maintain steady gait) versus regulation of leg loading (for injury avoidance and economy). Here we investigate how running guinea fowl manage this potential trade-off by comparing experimental data to predictions of hypothesis-based simulations of running over a terrain drop perturbation. We use a simple model to predict swing-leg trajectory and running dynamics. In simulations, we generate optimized swing-leg trajectories based upon specific hypotheses for task-level control priorities. We optimized swing trajectories to achieve i) constant peak force, ii) constant axial impulse, or iii) perfect disturbance rejection (steady gait) in the stance following a terrain drop. We compare simulation predictions to experimental data on guinea fowl running over a visible step down. Swing and stance dynamics of running guinea fowl closely match simulations optimized to regulate leg loading (priorities i and ii), and do not match the simulations optimized for disturbance rejection (priority iii). The simulations reinforce previous findings that swing-leg trajectory targeting disturbance rejection demands large increases in stance leg force following a terrain drop. Guinea fowl negotiate a downward step using unsteady dynamics with forward acceleration, and recover to steady gait in subsequent steps. Our results suggest that guinea fowl use swing-leg trajectory consistent with priority for load regulation, and not for steadiness of gait. Swing-leg trajectory optimized for load regulation may facilitate economy and injury avoidance in uneven terrain.

2011-01-01

The relations between young children’s mutual (reciprocated) and overall positive emotion (PE) with same- and other-gender peers and their social adjustment were explored. Children’s PE and peers’ PE were observed across the preschool year during peer interactions (N = 166; 46% girls; M age = 52 months). Results revealed that girls and boys had similar frequencies of overall PE and mutual PE when interacting with same-gender peers, but girls were marginally higher compared to boys in overall and mutual PE when interacting with other-gender peers. Girls and boys did not have greater rates of either type of PE after controlling for gender segregation during same- or other-gender interactions. Using structural equation modeling, children’s mutual PE, regardless of their gender, positively predicted indicators of positive adjustment (e.g., prosocial behavior, cooperation) and negatively predicted indicators of negative adjustment (e.g., hyperactivity, disruption, exclusion by peers). Children’s overall PE did not predict either type of adjustment. Findings support the importance of mutual PE for children’s development. PMID:21859190

Multiple designs, systems, methods and processes for controlling a system or plant using an extended active disturbance rejection control (ADRC) based controller are presented. The extended ADRC controller accepts sensor information from the plant. The sensor information is used in conjunction with an extended state observer in combination with a predictor that estimates and predicts the current state of the plant and a co-joined estimate of the system disturbances and system dynamics. The extended state observer estimates and predictions are used in conjunction with a control law that generates an input to the system based in part on the extended state observer estimates and predictions as well as a desired trajectory for the plant to follow.
