Data from longitudinal studies of adolescents carried out over the last ten years are reviewed to provide an integrated and dynamic perspective on the nature of friendships and processes of peer influence in adolescent drug involvement, within a general developmental perspective. Four interrelated questions are examined: What individual attributes are especially important in the formation of friendships among adolescents? Which of two processes, selection or socialization, account for the similarity in values and behaviors observed in ongoing friendship dyads, and how important is similarity in friendship formation and dissolution? What is the nature of friends' influence as compared to parents', and in which domains of adolescent's life do these influences exert themselves? What mechanisms, role modeling or social learning, underlie processes of interpersonal influences? Relational dyadic and triadic samples of adolescents matched to a parent and/or a best friend and observed at one point in time as well as over time provide important and relatively rare sources of data on processes of interpersonal influence. Sociodemographic characteristics are the strongest determinants of friendship formation, with participation in illicit drugs following next in importance. Both selection (assortative pairing) and socialization contribute to observed similarity in friendship pairs. Adolescents coordinate their choice of friends and their values and behaviors, in particular the use of marijuana, so as to maximize congruency in the friendship dyad. If there is a state of unbalance such that the friend's attitude or behavior is inconsistent with the adolescent's, the adolescent will either break off the friendship and seek another friend or will keep the friend and modify his or her own behavior. Both parents and peers can have strong influences on adolescents, depending upon the arena of influence. Parents are especially important for future life plans, while peers are most important for involvement in illicit drug use. However, for drug use itself, there are different patterns of influence depending upon the stage of drug involvement. Peers are especially important for initiation into marijuana use, while parental factors gain in importance in the transition from marijuana use to the use of other illicit drugs. Interpersonal influences of peers on ongoing marijuana and alcohol use result from modeling and imitation more than from social reinforcement and the transmission of values.
BACKGROUND: Friendship and sibling relationships differ in that there is an element of choice in friendships, whilst the latter represent a fixed and given relationship. The present study set out to investigate the temperamental correlates of friendships and sibling relationships, as well as to examine their genetic and environmental components. METHOD: Two hundred and twelve same-sex twin-pairs (102 MZ and 110 DZ; 104 male pairs and 108 female pairs) aged between 12 and 15, together with their parents, comprised the sample. The twins themselves reported on both negative and positive aspects of the two relationships, and all family members provided reports of the twins' temperament (mothers, fathers, and adolescent self-reports). RESULTS: Analyses revealed that negative aspects of both the sibling relationship and friendship were related to emotionality, while the positive aspects of these relationships were associated with sociability and activity. Genetic influences and the shared environment accounted for variance seen in the sibling relationship. In addition, nonshared environment accounted for a moderate amount of the sibling relationship variability and explained most of the variance for the friendship components. Finally, bivariate analyses of the covariance between temperament and close relationships highlighted the importance of nonshared environmental influences during adolescence. CONCLUSION: Three themes emerged. First, congruent temperamental expressions were seen across these two relationships' contexts. Second, friendship and the sibling relationship have distinct etiological profiles, indicating the child-specific character of adolescent friendships versus the reciprocal nature of the sibling relationship. Finally, the common influences to temperament and relationship quality provided evidence for the validity of adolescents' unique, nonshared experiences.
BACKGROUND: Overweight is the most common health problem that faces children and adolescents. Although the correlation among overweight, low self-esteem, and depression is well known, social isolation among overweight children and adolescents has not been studied. OBJECTIVE: To investigate social networks of overweight and normal-weight adolescents in a large, nationally representative sample. DESIGN: Cross-sectional, nationally representative cohort study. Population A total of 90 118 adolescents aged 13 to 18 years who were enrolled in the National Longitudinal Study of Adolescent Health, of which a 1:5 subsample was selected for detailed in-home assessment, including height and weight measurements (n = 17 557). Overweight was defined according to body mass index (>95th percentile for age and sex). MAIN OUTCOME MEASURES: This analysis focuses on the number of friendship nominations each adolescent received from other adolescents. The number of friendship nominations and other social network measures were calculated using statistical software. RESULTS: Overweight adolescents were more likely to be socially isolated and to be peripheral to social networks than were normal-weight adolescents. Although overweight adolescents listed similar numbers of friends as normal-weight adolescents, overweight adolescents received significantly fewer friendship nominations from others than were received by normal-weight adolescents (mean [SE] number of friendship nominations, 3.39 [0.08] vs 4.79 [0.04]; P<.001). Overweight adolescents were also more likely to receive no friendship nominations than were normal-weight adolescents (odds ratio, 1.71; 95% confidence interval, 1.39-2.20). Decreased television viewing (P<.001), increased levels of sports participation (P<.001), and increased participation in school clubs (P<.001) were associated with significantly more friendship nominations and higher network centrality scores among both overweight and normal-weight adolescents. CONCLUSIONS: Many overweight adolescents are socially marginalized. Such isolation may aggravate the social and emotional consequences of overweight in this age group.
Premature autonomy describes a developmental dynamic where parents of high-risk adolescents reduce their involvement and guidance when confronted with challenges of problem behaviour and the influence of deviant friendships. This dynamic was tested on the sample of Oregon Youth Study boys (N=206), whose family management practices and friendships were observed on videotaped interaction tasks. Latent growth curve models were used to examine longitudinal trends between deviant friendship interactions and family management. Direct observations of deviant friendship process at age 14 were associated with degradation in family management during adolescence. A comparison of antisocial and well-adjusted boys clarified that parents of antisocial boys (started early and persisted) decreased family management around puberty, in comparison to parents of well-adjusted boys who maintained high levels of family management through adolescence. In predicting late adolescent problem behaviour, there was a statistically reliable interaction between family management degradation and deviant peer involvement in adolescence in support of the premature autonomy hypothesis. Adolescent males involved in deviant friendships, and whose parents decreased their family management, were most likely to use marijuana and commit antisocial acts at age 18. The implications for interventions that target adolescents are discussed.
This study tested whether adolescents' attachment style is related to friendship interactions and perceptions of friendship quality. Attachment pairings were contrasted to examine whether dyad members' security of attachment or their models of others was more related to friendship. A total of 44 pairs of same-sex adolescent friends were videotaped as they engaged in an intimate conversation. Participants also completed self-report measures of attachment style and friendship quality. Compared with dyads with at least one insecure partner, dyads with two secure members interacted in ways that promoted a sense of connection with each other. In addition, they did not use as many clarification statements, suggesting a smooth conversational style between the friends. When friend pairs were examined based on positive or negative models of others (i.e., dismissing and fearful vs secure and preoccupied), there were no differences. The findings suggest that security of attachment, rather than type of insecurity, is most related to intimacy in friendship.
STUDY OBJECTIVE: To investigate cultural identity as a risk factor for mental health problems among adolescents. DESIGN: A cross sectional school based population survey. Mental health problems were measured using the strengths and difficulties questionnaire. Pupils were classified into one of four cultural identity types on the basis of friendship and clothing choices. SETTING: East London. PARTICIPANTS: 2623 adolescents (aged 11-14) from a representative sample of 28 schools in east London. RESULTS: In comparison with marginalised adolescents who chose friends from neither their own or other cultures, fewer mental health problems were found among adolescents making culturally integrated friendship choices (friends from own and other cultures: OR = 0.6, 0.4 to 0.9), boys making integrated friendship choices (OR = 0.45, 0.22 to 0.91), and specifically among Bangladeshi pupils with integrated friendship choices (OR = 0.15, 0.04 to 0.55). CONCLUSION: As measures of cultural identity, integrated friendship choices overall, and specifically for boys and Bangladeshi pupils, are associated with lower levels of adolescent mental health problems.
Adolescents may be influenced both by their friends' behaviors and by the features of their friendships. To examine both types of influence, seventh and eighth graders (N = 297) were asked in the fall of a school year to report their involvement and disruption at school. The students also described the positive and negative features of their best friendships. Teachers reported on the students' involvement, disruption, and grades. These assessments were repeated in the following spring. Students whose friends in the fall described themselves as more disruptive increased in self-reported disruption during the year. Girls' self-reported disruption was more influenced by that of their very best friend than was boys'. Students whose very best friendships had more positive features increased in their self-reported involvement during the year. Students whose friendships had more negative features increased in their self-reported disruption, but only if their friendships also had many positive features. The theoretical and practical implications of these findings, and the adequacy of different methods for estimating friends' influence, were discussed.
We assessed stigma affecting employment, health insurance, and friendships in 1,187 depressed patients from 46 U.S. primary care clinics. We compared stigma associated with depression, HIV, diabetes, and hypertension. Finally, we examined the association of depression-related stigma with health services use and unmet need for mental health care during a 6-month follow-up. We found that 67% of depressed primary care patients expected depression related stigma to have a negative effect on employment, 59% on health insurance, and 24% on friendships. Stigma associated with depression was greater than for hypertension or diabetes but not HIV. Younger men reported less stigma affecting employment. Women had more employment-related stigma but this was somewhat mitigated by social support. Other factors associated with stigma included ethnicity (associated with health insurance stigma) and number of chronic medical conditions (associated with health insurance and friendship related stigma). Stigma was not associated with service use, but individuals with stigma concerns related to friendships reported greater unmet mental health care needs. In summary, stigma was common in depressed primary care patients and related to age, gender, ethnicity, social support and chronic medical conditions. The relationship between stigma and service use deserves further study in diverse settings and populations.
Obtaining information from multiple informants is important when assessing youth depression. Past studies have utilized adults' reports of youths' emotional functioning and aggregate reports from classmates but have not considered close friends as reporters of depressive symptoms. This is surprising given the important roles of friends as companions and confidants. This study investigated relations between friend-reported depressive symptoms and youths' self-reports. From a larger sample of fifth-, seventh-, and ninth-grade participants, self-reports and friend reports of depressive symptoms and friend reports of friendship quality were available for a subset of 367 participants. Significant positive relations emerged between friend reports and self-reports of affective depressive symptoms for girls and youth in high-quality friendships. Relations between friend reports and self-reports were stronger for conduct-related than affective depressive symptoms and reached significance for boys as well as for girls and for youth in low-quality friendships as well as for youth in high-quality friendships. Implications for identifying at-risk youth are discussed.
The relative influence of adolescents closest friends and their friendship group on their cigarette smoking and alcohol use was investigated in a short-term, longitudinal study of 1,028 students in the 6th, 8th, and 10th grades in 2 school systems. The amount of influence over the school year was modest in magnitude and came from the closest friend for initiation of cigarette and alcohol use. Only the friendship group use predicted transition into current cigarette use, whereas only the close friend use predicted transition into current alcohol use. Both group and close friends independently contributed to the prediction of adolescents' drinking to intoxication. No difference in the amount of influence, was found between stable and unstable close friendships or friendship groups; neither grade nor gender of the adolescents related to the amount of influence.
