Friendship context matters: examining the domain specificity of alcohol and depression socialization among adolescents

Validation of the psychoactive substance refusal Self-Efficacy Questionnaire (PSRSEQ) in adolescent case-clients of social workers in Hong Kong

BACKGROUND

Self-efficacy is a key concept in various behavioral theories. Refusal self-efficacy is important in understanding issues related to psychoactive substance use. To facilitate related research, this study translated and validated the Chinese version of the 14-item Psychoactive Substance Refusal Self-efficacy Questionnaire (PSRSEQ) among adolescents. There is a debate about whether such a refusal self-efficacy scale should be unidimensional or multidimensional.

METHODS

A survey was conducted among 601 adolescent case-clients of social workers in Hong Kong from July 2021 to June 2022. Various psychometric properties were examined.

RESULTS

The confirmatory factor analysis (CFA) supported the original 3-factor structure of the PSRSEQ (emotional relief, opportunistic, and social facilitation refusal self-efficacy), which showed satisfactory psychometric properties (internal consistency, convergent validity in terms of significant negative correlations with the intention of psychoactive substance use in the next year and psychoactive substance use behavior in the past six months, and the absence of floor effect) but ceiling effect was obvious. Notably, unacceptable discriminant validity of one subscale and strong correlations among the three subscales were observed. In another set of analyses using two split-half subsamples, the exploratory factor analysis identified a 1-factor 14-item structure, which was confirmed by CFA and showed satisfactory psychometric properties.

CONCLUSIONS

The 1-factor PSRSEQ, instead of the one having a 3-factor structure, was preferred and recommended to assess psychoactive substance refusal self-efficacy among Chinese adolescents. It is warranted to validate the scale in other adolescent and age groups in future studies.

Influence of perceived peer behavior on engagement in self-damaging behaviors during the transition to university

As students transition to university, they experience significant social changes that can affect their behaviors, including self-damaging behaviors like disordered eating, problematic alcohol/drug use, suicidal thoughts, and non-suicidal self-injury (NSSI). Building on prior work, we examined the associations between (1) perceptions of peers' engagement in self-damaging behaviors predicting one's own subsequent engagement in such behaviors (i.e., socialization) and (2) one's own engagement in self-damaging behaviors predicting perceptions of peers' subsequent engagement in such behaviors (i.e., selection). We also examined whether these associations were moderated by the source of influence (close peer/acquaintance) and degree of social disconnection experienced by the student. First-year university students (N = 704) were asked to complete seven monthly surveys. Multilevel models indicated that when students perceived their close peers had engaged in NSSI or suicidal thinking, they had seven times greater odds of future engagement in the same behavior, implying that socialization increases the risk of these behaviors among university students. Perception of acquaintances' NSSI also predicted greater odds of a student's own NSSI the following month. Social disconnection increased the likelihood of matching own behaviors to perceptions of acquaintances' alcohol abuse, highlighting the importance of fostering connections/mentors to reduce self-damaging behaviors on college campuses. Furthermore, when students engaged in alcohol abuse, they had almost four times greater odds of reporting that their acquaintances abused alcohol the following month, emphasizing the importance of the wider social network in alcohol use behaviors.

Depression Socialization in Early Adolescent Friendships: The Role of Baseline Depressive Symptoms and Autonomous Functioning

There is mixed evidence for depression socialization, a process by which friends affect each other's level of depressive symptoms. The current study examined whether adolescents' baseline depressive symptoms and three dimensions of autonomous functioning (autonomy, peer resistance, and friend adaptation) make adolescents more or less sensitive to depression socialization, and how these dimensions of autonomous functioning were connected. In this preregistered, two-wave longitudinal study, participants completed questionnaires on depressive symptoms, autonomy, and peer resistance and participated in a task to assess friend adaptation. Participants were 416 Dutch adolescents (Mage = 11.60, 52.8% girls) across 230 close friend dyads. In contrast to expectations, results showed no significant depression socialization nor significant moderation. Furthermore, autonomy and peer resistance were related but distinct constructs, and not related to friend adaptation. These findings suggest that there is no depression socialization in early adolescence, regardless of level of autonomous functioning.

Turning to friends in preference to parents for support in early adolescence: does this contribute to the gender difference in depressive symptoms?

Introduction

Based on established evidence of gender differences in friendship patterns, and the vulnerability associated with early reliance on friends, we hypothesized that in 13-year-olds, a preference for turning to friends rather than parents for emotional support contributes to the gender difference in depressive symptoms.

Methods

Using a cross-sectional design, 671 adolescents (53.7% girls; mean age 13.11 ± 0.52 years) in a UK birth cohort [Wirral Child Health and Development Study (WCHADS)] reported turning to their parents and to their friends when distressed [Network of Relationships Inventory (NRI)] and depressed [Short Mood and Feelings Questionnaire (SMFQ)]. Preferentially turning to friends was assessed as turning to friends minus turning to parents for support. Analyses used path analysis using the gsem command in Stata.

Results

Girls had higher depressive symptoms than boys (p < .001). Consistent with the hypotheses, girls had higher scores than boys for preferentially turning to friends (p < .001). Preferentially turning to friends was associated with higher depressive symptoms (p < .001), and this mediated the gender difference in depressive symptoms (p < .001). The association between preferentially turning to friends and depressive symptoms was stronger for girls than for boys (p = .004).

Conclusions

In young adolescents, preferentially turning to friends over parents when distressed is common, and the association between preferentially turning and depressive symptoms is markedly higher in girls than in boys. This reflects either a gender difference in social vulnerability to depression or a greater impact of depression on the reliance on friends instead of parents in girls. While clarifying the directions of influence requires prospective study, these findings provide the first evidence that the assessment of depression in young adolescents should consider the degree of reliance on friends and parents.

Challenging behaviour in students with intellectual disabilities: the role of individual and classmates' communication skills

BACKGROUND

Children and adolescents with intellectual disabilities (ID) are at increased risk of developing challenging behaviour. Challenging behaviour may be partially explained by low individual communicative competences. However, communication involves at least two partners, thus outcomes may also vary according to each interaction partners' abilities. We therefore investigated the degree to which the interplay between individual and classmates' communication skills predicts changes in challenging behaviour among students with ID.

METHODS

This study used a longitudinal design with two measurement points across one school year. Challenging behaviour and communication skills were measured by teacher reports in 1125 students with ID attending special needs schools. Applying a multilevel approach, we investigated (1) whether higher individual communication skills at the first measurement were related to a subsequent decrease in challenging behaviour and (2) whether this effect was moderated by classmates' levels of communication skills. In addition, we examined (3) if classroom communication skills were indirectly related to a decrease in challenging behaviour by influencing individual communicative abilities.

RESULTS

Higher individual communication skills at the first measurement were significantly related to a decrease in general challenging behaviour over the school year. This effect was not moderated by classroom-level communication skills. However, classmates' communication skills exerted an indirect influence by enhancing individual communicative abilities. Further analyses suggested classroom contextual effects related to a decrease in several sub-domains of challenging behaviour.

CONCLUSIONS

The study results suggest that both individual communicative competences and those of the classroom context are relevant to understanding challenging behaviour development in ID. Perspectives for counteracting such behaviour in light of the present findings are discussed.

The role of parenting, self-compassion and friendships in depressive symptoms among young people in the UK and China

Self-compassion, being kind to oneself in difficult times, is a way of relating to oneself that promotes better mental health, but little is known about how self-compassion affects interpersonal relationships. The current study examined the association between self-compassion and adolescent depressive symptoms from an interpersonal perspective in different cultural contexts. Adolescents (N = 422/570, Mean age = 14.44/13.41, UK/China) completed questionnaires about their perceptions of their parents' behaviour towards them, self-compassion, friendships and depressive symptoms. Structural equation modelling revealed that positive parenting was positively associated with higher self-compassion, positive friendship quality, and with fewer depressive symptoms in both samples. Additionally, we confirmed a negative association between self-compassion and depressive symptoms. The pathway from positive parenting to lower depressive symptoms via higher self-compassion was also corroborated in both cultures. Contrary to our hypothesis, positive quality of friendship was associated with higher depressive symptoms in both countries. Conflicts were associated with more depressive symptoms in the Chinese sample only. There was evidence of a negative association between self-compassion and conflicts in the Chinese sample only. Finally, the direct association between self-compassion and depressive symptoms was greater in the UK sample, whereas in the Chinese sample, interpersonal factors were more strongly associated with self-compassion and depressive symptoms. Our findings suggest that self-compassion may be a useful therapeutic target to improve social functioning and mental health among adolescents and that it may be necessary to account for cross-cultural differences in interpersonal factors when designing psychological interventions.

Self-perceived social relationships are related to health risk behaviors and mental health in adolescents

Although changes have been observed in social relationships in the recent years, especially among younger generations, little evidence is available concerning factors associated with adolescents' perceived social relationships. In this study we investigated the association between self-perceived social relationships, health-related behaviors, biological maturation, and mental health in adolescents. This is a cross-sectional study conducted with 1,336 adolescents (605 boys and 731 girls) aged between 10 to 17 years from public schools. Self-perceived social relationships (family, friends, and teachers), feelings of stress and sadness, academic performance, tobacco smoking, alcohol and fat consumption, physical activity, and screen time were evaluated by a questionnaire. Biological maturation was assessed by the peak height velocity. We observed that worse perceived social relationships were associated with tobacco smoking (family and teachers), alcohol drinking (teachers), higher consumption of fat (teachers), greater feelings of stress (family and teachers) and sadness (family and friends), and poor academic achievement (friends and teachers).

"Adolescents who feel depressed are rejected but do not withdraw: A longitudinal study of ethnically diverse friendship networks in England, Sweden, and Germany"

Adolescents who feel depressed are likely to experience social isolation from friends. Previous studies have put forward at least four hypotheses that can account for the association between felt depression and social isolation. The hypotheses are: (1) adolescents who are rejected tend to feel more depressed, (2) adolescents who feel depressed tend to become rejected, (3) adolescents who withdraw from friends tend to feel more depressed, and (4) adolescents who feel depressed tend to withdraw from friends. The present study aims to test these four hypotheses in ethnically diverse contexts in three countries. Two waves of data from England (n = 515), Sweden (n = 1,228), and Germany (n = 869) were obtained from the Children of Immigrants Longitudinal Survey in Four European Countries (CILS4EU). One separate stochastic actor-oriented model of the longitudinal coevolution of friendship networks and felt depression was estimated for each of the three countries using the statistical package RSiena. The results consistently indicated that, in all three countries, adolescents who felt depressed were rejected by their peers. Also, the results consistently indicated that adolescents who felt depressed sought more friends, and the results therefore refuted the suggestion that adolescents who feel depressed withdraw from their friends. The findings of the study can inform health-promotion interventions that attempt to limit the social isolation of adolescents who feel depressed in ethnically diverse contexts. More specifically, the study suggests that the social isolation of adolescents who feel depressed may be limited through interventions that reduce the rejection that these adolescents experience from their peers.

Peer influence in adolescent drinking behavior: A meta-analysis of stochastic actor-based modeling studies

Objectives

To measure the effects of peer influence and peer selection on drinking behavior in adolescence through a rigorous statistical approach designed to unravel these interrelated processes.

Methods

We conducted systematic searches of electronic databases, thesis collections and conference proceedings to identify studies that used longitudinal network design and stochastic actor-oriented modeling to analyze drinking behavior in adolescents. Parameter estimates collected from individual studies were analyzed using multilevel random-effects models.

Results

We identified 26 articles eligible for meta-analysis. Meta-analyses for different specifications of the peer influence effect were conducted separately. The peer influence effect was positive for every specification: for average similarity (avSim) mean log odds ratio was 1.27 with 95% confidence interval [0.04; 2.49]; for total similarity (totSim) 0.46 (95% CI = [0.44; 0.48]), and for average alter (avAlt) 0.70 (95% CI = [-0.01; 1.41]). The peer selection effect (simX) was also positive: 0.46 (95% CI = [0.28; 0.63]). Conversion log odds ratio values to Cohen’s d gives estimates from 0.25 to 0.70, which is considered as medium to large effect.

Conclusions

Advances in methodology for social network analysis have made it possible to accurately estimate peer influence effects free from peer selection effects. More research is necessary to clarify the roles of age, gender, and individual susceptibility on the changing behavior of adolescents under the influence of their peers. Understanding the effects of peer influence should inform practitioners and policy makers to design and deliver more effective prevention programs.

Co-Rumination and Depressive Symptoms in Adolescence: Prospective Associations and the Mediating Role of Brooding Rumination

Although relationships between co-rumination and depressive symptoms have often been found, little research attention has been given to mechanisms underlying this association. The current study investigated brooding rumination as a mediator of the relationship between co-rumination and depressive symptoms. Analyses were performed on data of 1549 adolescents (53.4% girls; M_age = 12.93, range 9-17) using three waves of data with 1-year intervals. Mediated and indirect effects were investigated by means of cross-lagged analyses. The results indicated that co-rumination was not predictive of depressive symptoms 2 years later. However, co-rumination did have an indirect effect on prospective depressive symptoms through brooding rumination. Additional analyses looking into the directionality of effects showed that neither brooding rumination nor depressive symptoms were predictive of relative increases in one's tendency to co-ruminate. Multi-group analyses further showed that findings were not moderated by gender or age. The current study contributes to the growing literature on the role of interpersonal and intrapersonal affect-regulation styles in predicting depressive symptoms and suggests that passive and catastrophic problem talk with same-sex friends may get internalized into maladaptive and repetitive thinking patterns.

The endocrinology of female friendships: Cortisol and progesterone attunement after separation

Friendships constitute important relationships, and often function to reduce stress, but have been under-studied. In mother-child dyads, infants coordinate their stress response with their caregivers without experiencing the stressor themselves. The current study used a modified version of the Trier Social Stress Test to examine whether i) friends are physiologically attuned (i.e., cortisol and progesterone); ii) attunement differs as a function of social acceptance or rejection external to the dyad; and, iii) friends can 'catch' a stress response only through non-verbal cues. Friends showed both cortisol and progesterone attunement at the beginning of the study. Friends showed cortisol attunement across time and conditions. Friends' progesterone levels were significantly, but negatively associated across time and conditions. They did not, however, show a stress contagion as a result of one friend experiencing stress. These findings suggest that cortisol and progesterone play different roles in the attunement of stress and subsequent affiliation.

Social Influences on Drinking Trajectories From Adolescence to Young Adulthood in an Urban Minority Sample

OBJECTIVE

Research on the heterogeneity in drinking patterns of urban minorities within a socioecological framework is rare. The purpose of this study was to explore multiple, distinct patterns of drinking from adolescence to young adulthood in a sample of urban minority youth and to examine the influence of neighborhood, family, and peers on these trajectories.

METHOD

Data are from a longitudinal study of 584 (56% male) primarily Black (87%) youth who were first sampled in childhood based on their residence in low-income neighborhoods in Baltimore City and followed up annually through age 26. Data were analyzed using group-based trajectory modeling and multinomial logistic regression.

RESULTS

Modeling revealed six trajectories from ages 14 to 26: abstainer, experimenter, adult increasing, young adult increasing, adolescent limited, and adolescent increasing. Neighborhood disadvantage was a risk factor for drinking regardless of the timing of onset. Perceptions of availability, peer drinking, and parental approval for drinking were risk factors for underage drinking trajectories, whereas parental supervision was a significant protective factor. Positive social activities in neighborhoods was protective against increased drinking, whereas a decline in perceptions of peer drinking was associated with adolescent-limited drinking.

CONCLUSIONS

Our findings uniquely highlight the importance of developing interventions involving parents for urban minority youth for whom family is particularly relevant in deterring underage drinking. Perhaps most importantly, our data suggest that interventions that support positive social activities in disadvantaged neighborhoods are protective against adolescent drinking and altering perceptions of peer drinking may reduce adolescent drinking among low-income, urban minority youth.

The Intensity Effect in Adolescent Close Friendships: Implications for Aggressive and Depressive Symptomatology

This study examined the effect of close friendship intensity as a potential amplifier of an adolescent's preexisting tendencies toward depressive and aggressive symptoms. A diverse community sample of 170 adolescents and their closest friends was assessed via multiple methods, and adolescents were followed from age 16 to 17. Results supported the hypothesized effect, with more intense close friendships interacting with higher baseline levels of behavioral symptoms to predict greater relative increases in symptoms over time. Effects were observed for both depressive and aggressive symptoms, and appeared with respect to multiple observational measures of friendship intensity. Findings are interpreted as suggesting that seemingly disparate phenomena (e.g., co-rumination for depression and deviancy-training for aggression) may both be dependent upon the intensity of the adolescent's social connections.

Depressive symptoms are associated with social isolation in face-to-face interaction networks

Individuals with depressive symptoms are more likely to be isolated in their social networks, which can further increase their symptoms. Although social interactions are an important aspect of individuals' social lives, little is known about how depressive symptoms affect behavioral patterns in social interaction networks. This article analyzes the effect of depressive symptoms on social interactions in two empirical settings (N_total = 123, N_{dyadic relations} = 2,454) of students spending a weekend together in a remote camp house. We measured social interactions between participants with Radio Frequency Identification (RFID) nametags. Prior to the weekend, participants were surveyed on their depressive symptoms and friendship ties. Using state-of-the-art social network analysis methods, we test four preregistered hypotheses. Our results indicate that depressive symptoms are associated with (1) spending less time in social interaction, (2) spending time with similarly depressed others, (3) spending time in pair-wise interactions rather than group interactions but not with (4) spending relatively less time with friends. By "zooming in" on face-to-face social interaction networks, these findings offer new insights into the social consequences of depressive symptoms.

Peer social network processes and adolescent health behaviors: A systematic review

Research has highlighted the importance of peers for determining health behaviors in adolescents, yet these behaviors have typically been investigated in isolation. We need to understand common network processes operating across health behaviors collectively, in order to discern how social network processes impact health behaviors. Thus, this systematic review of studies investigated adolescent peer social networks and health behaviors. A search of six databases (CINAHL, Education Resources Information Centre, Embase, International Bibliography of the Social Sciences, Medline and PsycINFO) identified 55 eligible studies. The mean age of the participants was 15.1 years (range 13-18; 51.1% female). Study samples ranged from 143 to 20,745 participants. Studies investigated drinking (31%), smoking (22%), both drinking and smoking (13%) substance use (18%), physical activity (9%) and diet or weight management (7%). Study design was largely longitudinal (n = 41, 73%) and cross-sectional (n = 14, 25%). All studies were set in school and all but one study focused on school-based friendship networks. The Newcastle-Ottawa Scale was used to assess risk of bias: studies were assessed as good (51%), fair (16%) or poor (33%). The synthesis of results revolved around two network behavior patterns: 1) health behavior similarity within a social network, driven by homophilic social selection and/or social influence, and 2) popularity: health behavior engagement in relation to changes in social status; or network popularity predicting health behaviors. Adolescents in denser networks had statistically significant lower levels of harmful behavior (n = 2/2, 100%). Findings suggest that social network processes are important factors in adolescent health behaviors.

Sources of Social Influence on Adolescents' Alcohol Use

The present research examines social influences on self-reported frequency of drunkenness in a longitudinal sample of 1,439 adolescents (46% female, 90% White, mean age = 14 at baseline) with social network measures from friends, romantic partners, and romantic partners' friends. We build on past research by addressing multiple mechanisms of social influence-peers' frequency of drunkenness, alcohol-related attitudes, and unstructured socializing-across relationship types. Adolescents' drunkenness frequency increased when their friends' and partners' friends' drunkenness frequency increased and when their romantic partners' positive alcohol-related attitudes increased. Furthermore, the association between unstructured socializing and frequency of drunkenness was stronger for older than younger adolescents. Results advance understanding of the social transmission of alcohol use in adolescence and inform intervention efforts.

When Does Co-Rumination Facilitate Depression Contagion in Adolescent Friendships? Investigating Intrapersonal and Interpersonal Factors

Research supports the notion that adolescents' mental health is impacted by peers via contagion processes. A growing area of interest has been how co-rumination may influence depressive symptoms within friendships. The current study examined particular conditions under which co-rumination is especially likely to facilitate depression contagion. Participants were adolescents (N = 480, 49% female, M age = 14.6 years, 59.5% European American) paired in friendship dyads and assessed over 9 months. Characteristics of the adolescent (personal distress), of the friend (excessive reassurance seeking), and of the friendship (friendship quality) were considered. Moderated mediation analyses indicated that co-rumination facilitated depression contagion only under conditions of adolescents' high personal distress, friends' high excessive reassurance seeking, and high positive friendship quality. This research underscores the importance of attending to how and under what conditions depression contagion occurs within friendships in order to support adolescents' positive social and emotional development.

Homophily in delinquent behavior: The rise and fall of friend similarity across adolescence

This study examined age-related changes in friend similarity on delinquency to determine whether deviant behavior homophily peaks during mid-adolescence. A community sample of 1,663 male and 1,826 female Swedish youth from Grade 5 ( M = 11.21 years) to Grade 10 ( M = 16.25 years) provided self-reports of delinquency. Friendships were identified from nominations. Intraclass correlations revealed age group differences in friend delinquency similarity, independent of normative age-related changes in deviant behavior. Cross-sectional results indicated that similarity was greatest in the seventh grade ( M = 13.21 years). Longitudinal results from a subsample of participants revealed an increase in friend similarity from ages 11 to 13 (Grades 5 to 7) and a decline in friend similarity from ages 14 to 16 (Grades 8 to 10). The findings demonstrate that similarity between friends in delinquent behavior peaks in mid-adolescence, independent of normative age-related changes in participation in deviant acts.

What determines psychological well-being among Iranian female adolescents? Perceived stress may overshadow all determinants

Background: Mental health problems, as one of the most neglected issues among adolescents,are common during adolescence and emerging adulthood. The aim of present study was to investigate the determinants of psychological well being among female adolescents in Tabriz,Iran.

Methods: In this cross-sectional study, multi-stage cluster sampling was employed to recruit 289 female high school students to participate in the study during 2013–2014. A 3-section questionnaire was applied to collect data. Hierarchical linear regression analysis was applied to illustrate the variations in psychological wellbeing score on the basis of socio-demographic and psychological variables.

Results: Self-efficacy, hopefulness, happiness and life satisfaction were positively correlated (r> 0.400) and perceived stress was negatively associated with psychological well-being (r =-0.689). In the first model, satisfaction with family lifestyle (β = 0.168, P < 0.001) and perceived stress (β = -0.470, P < 0.001) were the most significant positive and negative predictors for psychological wellbeing, respectively (R² = 0.595, P < 0.001). In the second model (step 6),physical activity (β = -0.109, P < 0.019), have/had boyfriend (β = 0.237, P < 0.001), hopefulness(β = -0.130, P < 0.05) and happiness (-β = 0.387, P < 0.001) were significant predictors for perceived stress (R² = 0.453, P < 0.001).

Conclusion: Considering the various behavioral, mental and social predictors of psychological wellbeing, it seems that perceived stress has overshadowed the influence of a majority of the other factors. Such influence may be due to the specific cultural and context-based rules enforced for female adolescents in the Iranian community.

Implicit attitudes predict drinking onset in adolescents: Shaping by social norms

OBJECTIVE

Implicit attitudes toward alcohol predict drinking among adults and adolescents. If implicit attitudes reflected associations learned through direct experience with drinking, then they would likely only predict drinking among individuals who have previously consumed alcohol. In contrast, if implicit attitudes reflected indirect experience through social messages, they might also then predict future drinking, even among individuals with no drinking experience. In this study, we tested whether implicit attitudes would predict initiation of drinking for the first time, and whether parents' and friends' norms toward alcohol would influence the development of implicit attitudes.

METHOD

For this study, we followed 868 adolescents between the ages of 12 and 15 years for 3 years. Implicit attitudes were measured using the affect misattribution procedure (Payne, Cheng, Govorun, & Stewart, 2005; Payne, Govorun, & Arbuckle, 2008). Explicit intentions to drink and the frequency of drinking and binge drinking were measured at each of 3 annual waves.

RESULTS

Implicit attitudes toward alcohol predicted future drinking behavior 1 year later, and effects were similar for adolescents who had previously tried alcohol and for those who had not. To understand what factors might shape implicit attitudes among participants without drinking experience, we examined the role of parental norms and friends' norms toward drinking. Parental approval of drinking predicted the development of more positive implicit attitudes, which in turn predicted later drinking.

CONCLUSION

Implicit attitudes toward alcohol can develop in advance of direct experience drinking alcohol. Results have implications for the implicit processes underpinning adolescent drinking, and the processes by which implicit associations are learned. (PsycINFO Database Record

Peer Influence, Peer Selection and Adolescent Alcohol Use: a Simulation Study Using a Dynamic Network Model of Friendship Ties and Alcohol Use

While studies suggest that peer influence can in some cases encourage adolescent substance use, recent work demonstrates that peer influence may be on average protective for cigarette smoking, raising questions about whether this effect occurs for other substance use behaviors. Herein, we focus on adolescent drinking, which may follow different social dynamics than smoking. We use a data-calibrated Stochastic Actor-Based (SAB) Model of adolescent friendship tie choice and drinking behavior to explore the impact of manipulating the size of peer influence and selection effects on drinking in two school-based networks. We first fit a SAB Model to data on friendship tie choice and adolescent drinking behavior within two large schools (n = 2178 and n = 976) over three time points using data from the National Longitudinal Study of Adolescent to Adult Health. We then alter the size of the peer influence and selection parameters with all other effects fixed at their estimated values and simulate the social systems forward 1000 times under varying conditions. Whereas peer selection appears to contribute to drinking behavior similarity among adolescents, there is no evidence that it leads to higher levels of drinking at the school level. A stronger peer influence effect lowers the overall level of drinking in both schools. There are many similarities in the patterning of findings between this study of drinking and previous work on smoking, suggesting that peer influence and selection may function similarly with respect to these substances.

Internalizing Symptoms, Peer Substance Use, and Substance Use Initiation

This study used longitudinal survey and social network data covering sixth through ninth grades to test whether internalizing symptoms make early adolescents more prone to (1) exposure to and (2) influence by substance-using peers. Random effects regressions revealed that increases in symptoms were significantly associated with increases in the proportion of friends who used cigarettes, alcohol, and marijuana; some associations weakened across grades. Event history models revealed that the effect of friends' smoking on smoking initiation decreased as internalizing symptoms increased; symptoms did not moderate the effects of friends' alcohol and marijuana use on alcohol and marijuana use initiation. These findings counter the influence hypothesis of the co-occurrence of internalizing symptoms with substance use and partly support the exposure hypothesis.

The Role of Gender in Adolescents' Social Networks and Alcohol, Tobacco, and Drug Use: A Systematic Review

BACKGROUND

Despite previous research indicating an adolescents' alcohol, tobacco, and other drug (ATOD) use is dependent upon their sex and the sex composition of their social network, few social network studies consider sex differences and network sex composition as a determinant of adolescents' ATOD use behavior.

METHODS

This systematic literature review examining how social network analytic studies examine adolescent ATOD use behavior is guided by the following research questions: (1) How do studies conceptualize sex and network sex composition? (2) What types of network affiliations are employed to characterize adolescent networks? (3) What is the methodological quality of included studies? After searching several electronic databases (PsycINFO, EBSCO, and Communication Abstract) and applying our inclusion/exclusion criteria, 48 studies were included in the review.

RESULTS

Overall, few studies considered sex composition of networks in which adolescents are embedded as a determinant that influences adolescent ATOD use. Although included studies all exhibited high methodological quality, the majority only used friendship networks to characterize adolescent social networks and subsequently failed to capture the influence of other network types, such as romantic networks.

CONCLUSIONS

School-based prevention programs could be strengthened by (1) selecting and targeting peer leaders based on sex, and (2) leveraging other types of social networks beyond simply friendships.

Bully Victimization: Selection and Influence Within Adolescent Friendship Networks and Cliques

Adolescents tend to form friendships with similar peers and, in turn, their friends further influence adolescents' behaviors and attitudes. Emerging work has shown that these selection and influence processes also might extend to bully victimization. However, no prior work has examined selection and influence effects involved in bully victimization within cliques, despite theoretical account emphasizing the importance of cliques in this regard. This study examined selection and influence processes in adolescence regarding bully victimization both at the level of the entire friendship network and the level of cliques. We used a two-wave design (5-month interval). Participants were 543 adolescents (50.1% male, Mage = 15.8) in secondary education. Stochastic actor-based models indicated that at the level of the larger friendship network, adolescents tended to select friends with similar levels of bully victimization as they themselves. In addition, adolescent friends influenced each other in terms of bully victimization over time. Actor Parter Interdependence models showed that similarities in bully victimization between clique members were not due to selection of clique members. For boys, average clique bully victimization predicted individual bully victimization over time (influence), but not vice versa. No influence was found for girls, indicating that different mechanisms may underlie friend influence on bully victimization for girls and boys. The differences in results at the level of the larger friendship network versus the clique emphasize the importance of taking the type of friendship ties into account in research on selection and influence processes involved in bully victimization.

Happiness and its relation to psychological well-being of adolescents

In the present decade, adolescents' mental problems are known as critical problems which have many destructive consequences. This study aimed to measure students' happiness and psychological well-being status in a sample of high school students. The cross sectional study consisted of 403 randomly selected high school students in Tabriz, Iran. Numerous variables including general health status, happiness, self-efficacy, perceived stress, hopefulness and life satisfaction were measured by using self-reported written questionnaires. Significant relation observed between happiness and psychological well-being (r=0.48). Those students with good relationship and those who had reported to enjoy attending social events indicated better mental health status. No causal inferences were investigated due to the non-experimental nature of the study. The findings also revealed that students with higher happiness score have a better school performance. Integration of happiness promotion initiatives into the comprehensive school health programs is recommended to have pleasant environments for a healthy population of adolescents.

Are students prone to depression and suicidal thoughts?

INTRODUCTION

Depression may affect up to 9.8% of adolescents and young adults and is associated with significant life-long consequences. The aim of our study was to assess the association between symptoms of depression and demographic factors such as gender, having brothers or sisters, background (rural/small town or urban permanent place of residence), perceived financial status, current living arrangements, year and major area of study.

MATERIAL AND METHODS

One thousand one hundred eighty-three students of medical or similar faculties, 71% of whom were females, anonymously answered the Kutcher Adolescent Depression Scale (KADS) and completed a demographic questionnaire.

RESULTS

We found that 6.5% of all participants (n = 77) had depression according to Kutcher's criteria whereas 1.5% of them (n = 18) reported suicidal thoughts. We also observed the influence of such factors as gender (p < 0.009), year (p < 0.001), major area of study (p < 0.034), and financial status (p < 0.000-0.003), on depression scores. Moreover, depressive symptomatology was most frequent in subjects who were only children, in freshmen and in students of psychology (11.5%, 13.2% and 16.7% respectively). However, we did not observe an impact of such agents as students' permanent place of residence (p = 0.929) or current living arrangements on depressive symptoms (p = 0.940).

CONCLUSIONS

Susceptibility to depression fluctuates throughout the course of study and depends on factors associated with the study itself such as the student's major or year of study and other socio-demographic agents, i.e. gender or self-reported financial status.

Alcohol use among adolescent youth: the role of friendship networks and family factors in multiple school studies

To explore the co-evolution of friendship tie choice and alcohol use behavior among 1,284 adolescents from 12 small schools and 976 adolescents from one big school sampled in the National Longitudinal Study of Adolescent to Adult Health (AddHealth), we apply a Stochastic Actor-Based (SAB) approach implemented in the R-based Simulation Investigation for Empirical Network Analysis (RSiena) package. Our results indicate the salience of both peer selection and peer influence effects for friendship tie choice and adolescent drinking behavior. Concurrently, the main effect models indicate that parental monitoring and the parental home drinking environment affected adolescent alcohol use in the small school sample, and that parental home drinking environment affected adolescent drinking in the large school sample. In the small school sample, we detect an interaction between the parental home drinking environment and choosing friends that drink as they multiplicatively affect friendship tie choice. Our findings suggest that future research should investigate the synergistic effects of both peer and parental influences for adolescent friendship tie choices and drinking behavior. And given the tendency of adolescents to form ties with their friends' friends, and the evidence of local hierarchy in these networks, popular youth who do not drink may be uniquely positioned and uniquely salient as the highest rank of the hierarchy to cause anti-drinking peer influences to diffuse down the social hierarchy to less popular youth. As such, future interventions should harness prosocial peer influences simultaneously with strategies to increase parental support and monitoring among parents to promote affiliation with prosocial peers.

Willingness to drink as a function of peer offers and peer norms in early adolescence

OBJECTIVE

The goal of this study was to explore the effect of subjective peer norms on adolescents' willingness to drink and whether this association was moderated by sensitivity to peer approval, prior alcohol use, and gender.

METHOD

The sample was 1,023 middle-school students (52% female; 76% White; 12% Hispanic; M(age) = 12.22 years) enrolled in a prospective study of drinking initiation and progression. Using web-based surveys, participants reported on their willingness to drink alcohol if offered by (a) a best friend or (b) a classmate, peer norms for two referent groups (close friends and classmates), history of sipping or consuming a full drink of alcohol, and sensitivity to peer approval (extreme peer orientation). Items were re-assessed at two follow-ups (administered 6 months apart).

RESULTS

Multilevel models revealed that measures of peer norms were significantly associated with both willingness outcomes, with the greatest prediction by descriptive norms. The association between norms and willingness was magnified for girls, those with limited prior experience with alcohol, and youths with low sensitivity to peer approval.

CONCLUSIONS

Social norms appear to play a key role in substance use decisions and are relevant when considering more reactive behaviors that reflect willingness to drink under conducive circumstances. Prevention programs might target individuals with higher willingness, particularly girls who perceive others to be drinking and youths who have not yet sipped alcohol but report a higher perceived prevalence of alcohol consumption among both friends and peers.

Personality and externalizing behavior in the transition to young adulthood: the additive value of personality facets

PURPOSE

The directionality of effects in the associations between personality and externalizing behavior (i.e., delinquency, soft drugs use, and alcohol abuse) is unclear. Moreover, previous studies only examined personality trait domains when examining these associations, whereas personality facets underlying these broad domains provide more specificity. To address these limitations, the present study examined the directionality of effects between externalizing behavior and personality while employing a facet-level approach to personality.

METHODS

Cross-lagged panel models were employed to four annual measurement waves of longitudinal data on 485 Belgian-Caucasian late adolescents (87.4 % female; M age = 18.63 years, SD = 0.61). Participants filled out the NEO-FFI as a measure of personality, the Deviant Behavior Scale as a measure of delinquency, and single items for soft drugs use and alcohol abuse on all four measurement occasions.

RESULTS

The incremental value of personality facets over broad trait domains was demonstrated, as it was often the case that only some, but not all, facets underlying a specific trait domain were significantly associated with specific externalizing behaviors. Furthermore, linkages between personality and externalizing behavior were shown to be complex. Depending on the personality trait domain or facet and the specific behavior under investigation, the directionality of effects may differ.

CONCLUSIONS

To capture the full complexity of the linkages between personality and externalizing behavior, a facet approach to personality is recommended. This information is potentially important for clinicians, as it indicates which specific aspects of a broad trait domain affect, and are affected by, specific externalizing behaviors.

Risk and protection factors in the peer context: how do other children contribute to the psychosocial adjustment of the adolescent?

As children become adolescents, peers assume greater importance in their lives. Peer experiences can either help them thrive or negatively affect their psychosocial adjustment. In this review article definitions for the types of peer experiences are provided followed by an overview of common psychosocial issues encountered by adolescents. Past research that has pointed to risk and protection factors that emerge from peer experiences during adolescence and the role of peer influences in the context of current issues relevant to adolescent education are discussed. Research suggests that friendships with deviant peers, involvement in bullying and the experience of rejection from the overall peer group are related to adjustment problems, whereas friendships with prosocial and academically oriented peers and social acceptance in the peer group are related to healthy development. Friendship quality, popularity among peers, and involvement in friendship cliques cannot be clearly categorized as either positive or negative influences, because they interact with other factors in shaping the development of adolescents. The promotion of social skills and positive youth leadership as an integral part of the student's learning process in school is recommended.

Peer similarity and influence for weight-related outcomes in adolescence: a meta-analytic review

Weight-related problems, including obesity and disordered eating, have emerged as major public health concerns for adolescents. To address these deviations from healthy eating and weight regulation, prevention and intervention efforts have targeted the influence of peers. Yet, evidence that peers influence weight-related outcomes, often inferred from similarity among peers, is inconsistent. This meta-analytic review evaluated peer similarity and influence not only for body size and symptoms of disordered eating, but also for key determinants of obesity (food intake and physical activity levels) and eating pathology (body dissatisfaction and weight control strategies). For each of the six outcomes, data was summarized from 9 to 24 independent studies. Results revealed significant, non-trivial similarity among peers across outcome variables, with the exception of disordered eating. Findings indicated that resemblances among peers were unlikely to be solely the reflection of cognitive biases or the selection of alike friends, but may be partially due to influence. To better understand the influence of peers, further longitudinal research is needed, particularly focusing on the factors that moderate susceptibility to conformity.

Direct and Indirect Peer Socialization of Adolescent Nonsuicidal Self-Injury

This study examined direct and indirect forms of peer socialization of non-suicidal self-injury (NSSI) in adolescent friendship networks. Data were collected among 348 adolescents (55% females; Mage = 15.02 years; SD = 0.53) at 4 assessment waves. Stochastic actor-based models revealed no evidence for direct socialization of NSSI: adolescents whose friends reported higher NSSI did not increase their NSSI over time. However, indirect forms of socialization were found. After controlling for direct socialization and selection effects, friends' depressive symptoms predicted changes in male and female adolescents' NSSI and friends' impulsivity predicted changes in male adolescents' NSSI. Findings highlight the importance of extending peer influence research beyond the classical "modeling" paradigm by providing evidence that peers may indirectly socialize adolescents' NSSI.
