Patterns of Aggressive Behavior and Peer Victimization from Childhood to Early Adolescence: A Latent Class Analysis

The developmental period characterized by the transition from childhood and elementary school to early adolescence and middle school has been associated with increases in aggressive behavior and peer victimization. Few longitudinal studies, however, have examined the stability of aggression and victimization during this critical transition. This study uses latent class analysis (LCA) to examine patterns of aggressive behavior and victimization during the transition to middle school among urban, public school students (N = 458; Girls = 53%; Latino/a = 53%; M age at t1 = 10.2 years). Independent LCA models were conducted using self-reported data assessing subjects’ involvement in aggressive conduct and victimization during the spring semesters of grades four, five, and six. Elementary school students in the fourth grade initially belonged to one of four groups identified as aggressor, victim, aggressor-victim, and uninvolved latent classes. Contrary to prior research, membership in these classes changed significantly by the time students completed their first year of middle school with most youth participating in episodes of aggression and victimization during the transition. Six common paths that describe patterns of aggressive behavior and victimization from the last two years of elementary school to the first year of middle school were found. Findings are discussed in the context of social dominance theory and prior research that has found greater stability in aggression and victimization among early adolescents.     

The Association Between Cyber Victimization and Subsequent Cyber Aggression: The Moderating Effect of Peer Rejection

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.     

The Role of Peer Stress and Pubertal Timing on Symptoms of Psychopathology During Early Adolescence

Stress is known to amplify the link between pubertal timing and psychopathology. However, few studies have examined the role of peer stress as a context for this link. The present study examined the interaction between perceived pubertal timing and peer stress on symptoms of psychopathology in early adolescence. The sample consisted of 264 students (63% female; M _age = 12.40, SD = 1.00; 55% Caucasian, 23% African American, 7% Latino, 11% biracial and 4% other). Higher peer stress was associated with symptoms of anxiety/depression; this effect did not vary by timing or gender. However, early-maturing girls with high peer stress demonstrated higher rates of relational and overt aggression compared to other girls. Findings also suggested that late-maturing boys with high stress are at risk for aggression problems; however, due to the small number of boys, analyses were exploratory. Overall, results suggest that developmentally salient contexts as indicated by stressful peer experiences may pose unique threats to early maturing girls and possibly late-maturing boys.     

Sleep Disturbance and Depressive Symptoms in Adolescence: The Role of Catastrophic Worry

Depression is a common and debilitating disorder in adolescence. Sleep disturbances and depression often co-occur with sleep disturbances frequently preceding depression. The current study investigated whether catastrophic worry, a potential cognitive vulnerability, mediates the relationship between adolescent sleep disturbances and depressive symptoms, as well as whether there are gender differences in this relationship. High school students, ages 16–18, n = 1,760, 49 % girls, completed annual health surveys including reports of sleep disturbance, catastrophic worry, and depressive symptoms. Sleep disturbances predicted depressive symptoms 1-year later. Catastrophic worry partially mediated the relationship. Girls reported more sleep disturbances, depressive symptoms, and catastrophic worry relative to boys. The results, however, were similar regardless of gender. Sleep disturbances and catastrophic worry may provide school nurses, psychologists, teachers, and parents with non-gender specific early indicators of risk for depression. Several potentially important practical implications, including suggestions for intervention and prevention programs, are highlighted.     

Substance Use Attitudes among Urban Black Adolescents: The Role of Parent,Peer, and Cultural Factors

This study examined the influence of perceived parental, peer, and cultural factors on Black American adolescent attitudes toward substance use. One-hundred-eight Black American youth (grades 9–12) from economically disadvantaged urban neighborhoods of New York, completed self-report measures on: (a) parent-child involvement, parental supervision, and parent attitudes toward high risk behaviors; (b) peer bonds and peer attitudes toward high risk behaviors; and (c) ethnic identity, parental racial socialization, and extended family support. Youth disapproval of substance use was positively associated with higher perceived levels of peer and parental disapproval of high risk behaviors, parental supervision, and ethnic identity. Youth who reported parental messages about racial discrimination without balanced parental messages about racial pride and racial equality were more likely to approve substance use.

Exposure to Violence in Adolescence and Precocious Role Exits

Exposure to violence is a serious public health concern that compromises adolescents by affecting their behavior and psychological well-being. The current study advances knowledge about the consequences of exposure to violence in adolescence by applying a life course perspective to evaluate the developmental implications of adolescents’ exposure to violence. In particular, drawing on a sample of 11,949 school-aged adolescents in the U.S., we examine whether exposure to violence in adolescence is associated with precocious role exits that some adolescents experience. Exposure to violence is conceptualized as including both direct (i.e., experiencing physical victimization) and indirect exposure (i.e., witnessing others’ victimization). Three types of direct exposure to violence are examined: street, intimate partner, and family victimization, as well as four types of indirect exposure including: street, peer, and school violence as well as exposure to family/friend suicide. Using three waves of longitudinal data from the Add Health Study, we find that exposure to violence is associated with greater risks of running away from home, dropping out of high school, having a child, attempting suicide, and coming into contact with the criminal justice system in later adolescence. In addition, risks depend upon the relational context in which the exposure to violence occurred, risks increase with greater exposure to violence, and risks are, for the most part, highest for those youth exposed to both indirect and direct violence in adolescence.

Relational Victimization and Depressive Symptoms in Adolescence: Moderating Effects of Mother, Father, and Peer Emotional Support

Adolescence heralds a unique period of vulnerability to depressive symptoms. This longitudinal study examined relational victimization in adolescents?? peer relationships as a unique predictor of depressive symptoms among a primarily (85%) Caucasian sample of 540 youth (294 females) concurrently and across a 6-year period. The moderating effects of emotional support received from mothers, fathers, and peers on the association between relational victimization and adolescents?? depressive symptoms were also investigated. Findings revealed that adolescents who were relationally victimized consistently had higher depressive symptoms than their non-victimized peers. However, high levels of emotional support from fathers buffered this relationship over time. Emotional support from mothers and peers also moderated the longitudinal relationship between relational victimization and depressive symptoms, with high levels of support predicting increases in adolescents?? symptoms. Relational victimization presents a clear risk for depressive symptoms in adolescence, and emotional support may serve either a protective or vulnerability-enhancing role depending on the source of support.     

Different Kinds of Lonely: Dimensions of Isolation and Substance Use in Adolescence

Social isolation is broadly associated with poor mental health and risky behaviors in adolescence, a time when peers are critical for healthy development. However, expectations for isolates’ substance use remain unclear. Isolation in adolescence may signal deviant attitudes or spur self-medication, resulting in higher substance use. Conversely, isolates may lack access to substances, leading to lower use. Although treated as a homogeneous social condition for teens in much research, isolation represents a multifaceted experience with structurally distinct network components that present different risks for substance use. This study decomposes isolation into conceptually distinct dimensions that are then interacted to create a systematic typology of isolation subtypes representing different positions in the social space of the school. Each isolated position’s association with cigarette, alcohol, and marijuana use is tested among 9^th grade students (n?=?10,310, 59% female, 83% white) using cross-sectional data from the PROSPER study. Different dimensions of isolation relate to substance use in distinct ways: unliked isolation is associated with lower alcohol use, whereas disengagement and outside orientation are linked to higher use of all three substances. Specifically, disengagement presents risks for cigarette and marijuana use among boys, and outside orientation is associated with cigarette use for girls. Overall, the adolescents disengaged from their school network who also identify close friends outside their grade are at greatest risk for substance use. This study indicates the importance of considering the distinct social positions of isolation to understand risks for both substance use and social isolation in adolescence.     

Peer Influences on Moral Disengagement in Late Childhood and Early Adolescence

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

Depression,Anxiety, and Peer Victimization: Bidirectional Relationships and Associated Outcomes Transitioning from Childhood to Adolescence

Experiences of depression, anxiety, and peer victimization have each been found to predict one another, and to predict negative outcomes in the domains of school connectedness, social functioning, quality of life, and physical health. However, the common co-occurrence of depression, anxiety, and peer victimization experiences has made it difficult to disentangle their unique roles in these associations. The present study thus sought to characterize the precise nature of the bidirectional relationships between depressive symptoms, anxiety, and victimization over time, and to examine their unique sequelae during the transition from childhood to early adolescence. Longitudinal multi-informant (child-reported, parent-reported, and teacher-reported) data from a nationally representative sample were analyzed using path analysis when the study child was aged 10–11 (n=?4169; M_age?=?10.3; 48.8% female) and aged 12–13 (n=?3956; M_age?=?12.4; 48.2% female). Depressive symptoms, anxiety, and peer victimization had small but significant unique bidirectional relationships. All three constructs also uniquely and prospectively predicted poorer life functioning across all domains examined. These results demonstrate that current interventions should broaden their scope to simultaneously target depression, anxiety, and peer victimization, as each of these experiences independently act as additive risk factors for subsequent negative outcomes.

     

Trajectories of Peer Social Influences as Long-term Predictors of Drug Use from Early Through Late Adolescence

The present study analyzed the long-term effects of perceived friend use and perceived peer use on adolescents’ own cigarette, alcohol and marijuana use as a series of parallel growth curves that were estimated in two developmental pieces, representing middle and high school (N = 1,040). Data were drawn from a large drug abuse prevention trial, the Midwestern Prevention Project (MPP). Results showed that both perceived peer and friend cigarette use predicted own cigarette use within and across the adolescent years. For own alcohol and marijuana use, peer and friend influences were limited primarily to middle school. The findings suggest that strategies for counteracting peer and friend influences should receive early emphasis in prevention programs that are targeted to middle school. The findings also raise the question of whether cigarette use may represent a symbol of peer group identity that is unlike other drug use, and once formed, may have lasting adverse effects through the adolescent years.

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.     

Differentiating Peer Contexts and Risk for Adolescent Substance Use

The peer context is perhaps the most salient, robust predictor of an adolescent's substance use. However, in previous studies, the peer context is often poorly defined. The current study examined 3 models to understand how substance use within best friendships, peer cliques, and social crowds predicts adolescents' substance involvement. A sample of 377 high school juniors and seniors completed surveys assessing substance use and peer relationships. Results suggest that each of these 3 dimensions of the peer context uniquely predict adolescent substance use. Moreover, these peer contexts interacted in the prediction of adolescents' substance use such that adolescents who were more highly embedded in substance-using peer contexts showed greater risk for substance use whereas adolescents with substance-using best friends showed a reduced risk for substance use if they had other close friends who were less involved with substances.
