Reconsidering the failure model: Using a genetically controlled design to assess the spread of problems from reactive aggression to internalizing symptoms through peer rejection across the primary school years.

According to the failure model (Patterson & Capaldi, 1990), peer rejection is the intermediary link between problem behaviors and internalizing symptoms. The present study tested the model with 464 monozygotic and same-sex dizygotic twin pairs (234 female, 230 male dyads). Teacher-reported reactive aggression and internalizing symptoms, and peer-reported peer rejection were collected at ages 6, 7, and 10 (from 2001 to 2008). Support for the failure model emerged in conventional non-genetically controlled analyses, but not twin-difference score analyses (which remove shared environmental and genetic contributions). Univariate biometric models attributed minimal variance in failure model variables to shared environmental factors, suggesting that genetic factors play an important unacknowledged role in developmental pathways historically ascribed to nonshared experiences in the failure model.

Profiles of Loneliness and Ostracism During Adolescence: Consequences, Antecedents, and Protective Factors.

This longitudinal study (N = 1078, 46% boys; 54% girls) examined profiles of loneliness and ostracism during adolescence and their consequences and antecedents. Longitudinal latent profiles analyses identified four distinct profiles: (1) High emotional loneliness (25%), High and increasing social loneliness (15%), High peer exclusion and high social impact (9%) and No peer problems (51%). Subsequent internalizing problems were typical for the High and increasing social loneliness profile and externalizing problems for the High emotional loneliness and High peer exclusion and high social impact profiles. Furthermore, effortful control, prosocial skills, and relationship quality with parents and teachers were highest in the No peer problems profile, whereas the High and increasing social loneliness profile had the lowest self-esteem and was characterized by low surgency/extraversion, high affiliativeness, and high negative affectivity.

More about being fun: Making friends to maximize social status.

OBJECTIVE: Children perceived by peers as someone who is fun reap interpersonal rewards, but little is known about what makes someone fun or how being fun leads to social success. The present study is designed to identify what qualities makes someone fun and how being fun leads to social success. METHOD: Two studies of children in primary and middle school are reported. Participants in the present investigation attended a public-school representative of Florida school children in terms of ethnicity and income. In the first study, 351 (179 girls, 172 boys) students (8-11 years old) completed surveys twice (M = 8.5 weeks apart) during an academic year, describing the qualities of "someone who is fun." RESULTS: At both time points, kindness and humor were rated as more important than buffoonery. In the second study, 394 (210 girls, 184 boys) students (8-13 years old) completed peer nomination surveys thrice (M = 8.5 weeks apart) during an academic year. Replicating previous findings, being fun predicted increases in social status (i.e., likeability and popularity). CONCLUSIONS: Unique to this study, full longitudinal mediation analyses indicated that being perceived as fun early in the school year predicted friend gain from the beginning to the middle of the school year, which, in turn, predicted increases in perceived likeability and popularity from the middle to the end of the school year. The findings were unique to being fun. Kindness and humor did not predict friend gain.

Adolescents with Few Friend Alternatives are Particularly Susceptible to Influence from Friends.

Friend influence in adolescence is well-documented, but the characteristics that contribute to individual differences in susceptibility to influence are not well understood. The present study tests the novel hypothesis that within a friend dyad, having fewer friends than one's partner (i.e., relative lack of alternatives) increases susceptibility to influence as it reduces dissimilarity and thereby promotes compatibility. Drawn from diverse California (USA) public middle schools, participants were 678 adolescents (58% girls) in reciprocated friendships that were stable from the fall to the spring of sixth grade (M = 11.53 years old). Longitudinal Actor-Partner Interdependence Models assessed peer influence, operationalized as individual change in the direction of increased friend similarity. Consistent with the hypothesis, partners with fewer friends were influenced by partners with relatively more friends in self-reported social anxiety and somatic complaints, as well as teacher-reported academic engagement and prosocial behavior. Academic engagement was the only domain wherein partners with more friends were also influenced by partners with relatively fewer friends. For those with few friends, conformity (i.e., becoming more similar to a partner) can be an important strategy to promote compatibility for strengthening existing friendships.

The Perils of Not Being Attractive or Athletic: Pathways to Adolescent Adjustment Difficulties Through Escalating Unpopularity.

Adolescents who lack traits valued by peers are at risk for adjustment difficulties but the mechanisms responsible for deteriorating well-being have yet to be identified. The present study examines processes whereby low athleticism and low attractiveness give rise to adolescent adjustment difficulties. Participants were public middle school students (ages 10 to 13 years, Mage = 11.54, SDage = 1.00) in the USA and Lithuania (300 girls, 280 boys; 52.7% girls). Self-reports of alcohol misuse and loneliness were collected three times during an academic year (M = 12.3 week intervals). Athleticism, attractiveness, unpopularity, and peer rejection were assessed through peer nominations. Full longitudinal mediation analyses examined direct and indirect pathways from stigmatized traits (i.e., low athleticism, low attractiveness) to adjustment difficulties (i.e., alcohol misuse, loneliness) through two indices of low peer status: unpopularity and rejection. The results indicated that the possession of stigmatized traits predicted escalating unpopularity, which, in turn, predicted increasing adjustment difficulties. Similar indirect associations did not emerge with rejection as a mediator, underscoring the unique role of power and prominence (and the lack thereof) in socioemotional development. The findings underscore the adjustment risks and interpersonal challenges that confront children and adolescents who lack traits valued by peers.

Being nice and being mean: Friend characteristics foreshadow changes in perceptions of relationship negativity.

This study examines the proposition that friend characteristics forecast changes in perceptions of relationship negativity. The participants (ages 9 to 11) were 240 pre- and young adolescents (114 boys, 126 girls) involved in 120 same-sex best friendships that were stable across a period of 4 to 12 weeks. Each friend described perceptions of negativity in their relationship. Prosocial behavior and relational aggression were assessed via peer nominations. Dyadic analyses indicated that one friend's prosocial behavior and relational aggression uniquely forecast changes in the other friend's perception of negativity in the relationship. Greater initial levels of prosocial behavior anticipated decreases in perceived negativity, whereas greater initial levels of relational aggression forecast increases in perceived negativity.

Perceptions of Positive Parenting Predict Increases in Resilience for Low Neurotic and High Agreeable Adolescents.

This study examines whether adolescent personality moderates longitudinal associations between perceived parenting practices and changes in adolescent resilience. A community sample of 442 (224 boys, 218 girls) Lithuanian adolescents completed surveys twice, one year apart, beginning in Grade 11 (M=17.1 years old). Adolescent self-reports described resilience, personality (neuroticism and agreeableness), and perceptions of positive parenting (support and monitoring). Adolescent personality moderated associations between initial perceptions of parenting and changes in resilience. Monitoring and support anticipated greater resilience for adolescents low but not high on neuroticism. Monitoring also anticipated greater resilience for adolescents high but not low on agreeableness. Consistent with the vantage-resistance hypothesis, the results suggest that neuroticism and disagreeableness interfere with the child's ability to profit from positive environmental experiences.

Conflict Moderates the Longitudinal Association between Aggression with Classmates and Popularity: Leveraging Disagreements into Peer Status.

The present study tests the hypothesis that conflict amplifies longitudinal associations from aggressiveness and disruptiveness to classroom popularity. Participants were 356 (181 girls, 172 boys) Florida primary school students (ages 8-12). The results revealed that higher initial levels of peer-reported aggression, and disruptiveness were associated with increases in peer-reported popularity, particularly for children who report frequent conflict with classmates. The findings highlight a hitherto unexplored avenue through which aggressive and disruptive children attain status in the peer group.

Reciprocal Patterns of Peer Speech in Preschoolers with and without Hearing Loss.

Children with hearing loss often attend inclusive preschool classrooms aimed at improving their spoken language skills. Although preschool classrooms are fertile environments for vocal interaction with peers, little is known about the dyadic processes that influence children's speech to one another and foster their language abilities and how these processes may vary in children with hearing loss. We used new objective measurement approaches to identify and quantify children's vocalizations during social contact, as determined by children's proximity and mutual orientation. The contributions of peer vocalizations to children's future vocalizations and language abilities were examined in oral language inclusion classrooms containing children with hearing loss who use hearing aids or cochlear implants and their typically hearing peers. Across over 600 hours of recorded vocal interactions of twenty-nine 2.5-3.5 year olds (16 girls) in three cohorts of children in a classroom, we found that vocalizations from each peer on a given observation predicted a child's vocalizations to that same peer on the subsequent observation. Children who produced more vocalizations to their peers had higher receptive and expressive language abilities, as measured by a standardized end-of-year language assessment. In fact, vocalizations from peers had an indirect association with end-of-year language abilities as mediated by children's vocalizations to peers. These findings did not vary as a function of hearing status. Overall, then, the results demonstrate the importance of dyadic peer vocal interactions for children's language use and abilities.

Toward understanding the functions of peer influence: A summary and synthesis of recent empirical research.

Compelling evidence demonstrates that peer influence is a pervasive force during adolescence, one that shapes adaptive and maladaptive attitudes and behaviors. This literature review focuses on factors that make adolescence a period of special vulnerability to peer influence. Herein, we advance the Influence-Compatibility Model, which integrates converging views about early adolescence as a period of increased conformity with evidence that peer influence functions to increase affiliate similarity. Together, these developmental forces smooth the establishment of friendships and integration into the peer group, promote interpersonal and intragroup compatibility, and eliminate differences that might result in social exclusion.

A Test of the Bistrategic Control Hypothesis of Adolescent Popularity.

Resource Control Theory (Hawley, 1999) posits a group of bistrategic popular youth who attain status through coercive strategies while mitigating fallout via prosociality. This study identifies and distinguishes this bistrategic popular group from other popularity types, tracing the adjustment correlates of each. Adolescent participants (288 girls, 280 boys; Mage  = 12.50 years) completed peer nominations in the Fall and Spring of the seventh and eighth grades. Longitudinal latent profile analyses classified adolescents into groups based on physical and relational aggression, prosocial behavior, and popularity. Distinct bistrategic, aggressive, and prosocial popularity types emerged. Bistrategic popular adolescents had the highest popularity and above average aggression and prosocial behavior; they were viewed by peers as disruptive and angry but were otherwise well-adjusted.

Being fun: An overlooked indicator of childhood social status.

OBJECTIVE: The present study concerns an overlooked trait indicator of childhood peer status: Being fun. The study is designed to identify the degree to which being fun is uniquely associated with the peer status variables of likeability and popularity. METHOD: Two studies of children in grades 4 to 6 (ages 9 to 12) are reported. The first involved 306 girls and 305 boys attending school in northern Colombia. The second involved 363 girls and 299 boys attending school in southern Florida. Students completed similar peer nomination inventories, once in the first study and twice (8 weeks apart) in the second. RESULTS: In both studies, being fun was positively correlated with likeability and popularity. In the second study, being fun predicted subsequent changes in likeability and popularity, after controlling for factors known to be related to each. Initial likeability and popularity also predicted subsequent changes in perceptions of being fun. CONCLUSIONS: Anecdotal evidence suggests that children are intensely focused on having fun. The findings indicate that this focus extends beyond the immediate rewards that fun experiences provide; some portion of peer status is uniquely derived from the perception that one is fun to be around.

Differences in Internalizing Symptoms Anticipate Adolescent Friendship Dissolution.

This study examined the degree to which internalizing symptoms predict adolescent friendship instability. A total of 397 adolescents identified 499 same-sex reciprocated friendships that originated in the seventh grade (M = 13.18 years). Discrete-time survival analyses were conducted with Grade 7 peer, teacher, and self-reports of internalizing symptoms as predictors of friendship dissolution across Grades 8-12. Differences between friends in depressive symptoms, anxiety symptoms, and (for boys only) submissiveness predicted subsequent friendship dissolution. Individual levels of these variables did not predict friendship dissolution, even at extreme or clinical levels. The findings suggest that friendship instability arising from internalizing problems stems from dissimilarity between friends rather than the presence of psychopathological symptoms on the part of one friend.

Math interest and self-concept among latino/a students: Reciprocal influences across the transition to middle school.

INTRODUCTION: Psychological factors like math interest and self-concept typically decline between late childhood and early adolescence; both are key to math achievement. The present study examined the reciprocal interplay between math interest and self-concept across the transition into middle school, and whether associations are moderated by success attributions. METHODS: A total of 263 (120 boys, 143 girls) Latino students (Mage = 10.5 years at outset) from an agricultural community in California (USA) completed surveys at three time points, from the end of primary school to the first year of middle school. Surveys measured math self-concept and math interest, as well as attributions to success in math. Cross-lagged panel models examined possible bidirectional associations between math self-concept and math interest, and whether attributions of success moderated these association. RESULTS: Lower initial levels of math self-concept anticipated greater declines in math interest, an association that was buffered by attributions of math success. The smallest declines in math interest occurred among adolescents who had both the highest math self-concept and were most inclined to attribute success in math to internal factors like studying. These associations remained when potential confounding variables (e.g., school grades, conduct problems) were included. CONCLUSION: The results replicate, in an understudied sample of Latino/a youth, the oft-reported link from low math self-concept to declining interest in math. Unique to this study is evidence of the protection afforded by belief in the efficacy of studying. The findings offer important guidance for teachers and parents seeking to mobilize resources for underperforming students.

Derisive Parenting Fosters Dysregulated Anger in Adolescent Children and Subsequent Difficulties with Peers.

Bullying and victimization are manifest in the peer social world, but have origins in the home. Uncertainty surrounds the mechanisms that convey problems between these settings. The present study describes the indirect transmission of hostility and coercion from parents to adolescent children through emotional dysregulation. In this model, derisive parenting-behaviors that demean or belittle children-fosters dysregulated anger, which precipitates peer difficulties. A total of 1409 participants (48% female; Mage = 13.4 years at the outset) were followed across secondary school (Grades 7-9) for three consecutive years. The results indicated that derisive parenting in Grade 7 was associated with increases in adolescent dysregulated anger from Grade 7 to 8, which, in turn, was associated with increases in bullying and victimization from Grade 8 to 9. The findings suggest that parents who are derisive, have children who struggle with emotional regulation and, ultimately, with constructive peer relationships.

The gene-environmental architecture of the development of adolescent substance use.

BACKGROUND: Using a longitudinal twin design and a latent growth curve/autoregressive approach, this study examined the genetic-environmental architecture of substance use across adolescence. METHODS: Self-reports of substance use (i.e. alcohol, marijuana) were collected at ages 13, 14, 15, and 17 years from 476 twin pairs (475 boys, 477 girls) living in the Province of Quebec, Canada. Substance use increased linearly across the adolescent years. RESULTS: ACE modeling revealed that genetic, as well as shared and non-shared environmental factors explained the overall level of substance use and that these same factors also partly accounted for growth in substance use from age 13 to 17. Additional genetic factors predicted the growth in substance use. Finally, autoregressive effects revealed age-specific non-shared environmental influences and, to a lesser degree, age-specific genetic influences, which together accounted for the stability of substance use across adolescence. CONCLUSIONS: The results support and expand the notion that genetic and environmental influences on substance use during adolescence are both developmentally stable and developmentally dynamic.

Shyness, Preference for Solitude, and Adolescent Internalizing: The Roles of Maternal, Paternal, and Best-Friend Support.

The researchers examined differential outcomes related to two distinct motivations for withdrawal (preference for solitude and shyness) as well as the possibility that support from important others (mothers, fathers, and best friends) attenuate any such links. Adolescents (159 males, 171 females) reported on their motivations to withdraw, internalizing symptoms, and relationship quality in eighth grade, as well as their anxiety and depression in ninth grade. Using structural equation modeling, the authors found that maternal support weakened the association between shyness and internalizing problems; friend support weakened the association between preference for solitude and depression; and friend support strengthened the association between shyness and depression. Results suggest that shy adolescents may not derive the same benefits from supportive friendships as their typical peers.

Best Friend Influence Over Adolescent Problem Behaviors: Socialized by the Satisfied.

The present study was designed to examine best friend influence over alcohol intoxication and truancy as a function of relative perceptions of friendship satisfaction. The participants were 700 adolescents (306 boys, 394 girls) who were involved in same-sex best friendships that were stable from one academic year to the next. Participants completed self-report measures of alcohol intoxication frequency and truancy at 1-year intervals. Each member of each friendship dyad also rated his or her satisfaction with the relationship. At the outset, participants were in secondary school (approximately 13-14 years old) or high school (approximately 16-17 years old). More satisfied friends had greater influence than less satisfied friends over changes in intoxication frequency and truancy. Problem behaviors of less satisfied friends increased over time if the more satisfied friend reported relatively higher, but not relatively lower, initial levels of drinking or truancy. The results support the hypothesis that adolescent friends are not similarly influential. The power to socialize, for better and for worse, rests with the partner who has a more positive perception of the relationship.

Maternal Psychological Control and Its Association with Mother and Child Perceptions of Adolescent Adjustment: More Evidence on the Strength of Shared Perspectives.

Mothers and adolescents hold distinct albeit correlated views of their relationship and of one another. The present study focuses on disentangling these independent views. Concurrent associations between maternal psychological control and children's adjustment are examined at two time points in order to identify the degree to which associations reflect (a) views that are shared by mothers and adolescents, and (b) views that are unique to mothers and adolescents. A total of 123 (56 % female) U.S. Latino/a adolescents (M = 10.4 years old at the outset) and their mothers reported on maternal psychological control, children's conduct problems, and children's anxiety, twice within a 5-month period. Data were collected at the close of primary school when the adolescents were in grade 5 and again at the beginning of middle school, when they were in grade 6. Results from conventional correlations indicated that mother- and adolescent-reports yielded similar associations between maternal psychological control and adolescent adjustment. Common fate model analyses partitioned results into variance shared across mother and adolescent reports and variance unique to mother and adolescent reports. Results differed for anxiety and conduct problems. Shared views indicated that greater maternal psychological control was associated with heightened child conduct problems; there were no associations unique to either reporter. In contrast, unique reporter views indicated that greater maternal psychological control was associated with child anxiety; there were no associations involving shared views. Although mother- and adolescent-reports agree that maternal psychological control is correlated with children's adjustment, there is considerable divergence in results when associations are partitioned according to shared and unique reporter views. Associations between maternal psychological control and children's anxiety are more apt to be inflated by same-reporter variance bias than are associations between maternal psychological control and children's conduct problems.

A Survival Analysis of Adolescent Friendships: The Downside of Dissimilarity.

The present study examined whether adolescent friendships dissolve because of characteristics of friends, differences between friends, or both. Participants were 410 adolescents (201 boys, 209 girls; mean age = 13.20 years) who reported a total of 573 reciprocated friendships that originated in the seventh grade. We conducted discrete-time survival analyses, in which peer nominations and teacher ratings collected in Grade 7 predicted the occurrence and timing of friendship dissolution across Grades 8 to 12. Grade 7 individual characteristics were unrelated to friendship stability, but Grade 7 differences in sex, peer acceptance, physical aggression, and school competence predicted subsequent friendship dissolution. The findings suggest that compatibility is a function of similarity between friends rather than the presence or absence of a particular trait.
