Religiosity of Adolescents and their Friends and Network Associates: Homophily and Associations With Antisocial Behavior

This study assessed the similarity of adolescents and their friends and peer network associates in religiosity and the extent to which these relationships were associated with antisocial behavior. The sample included 1010 Indonesian (480 male, 530 female) 8th (13.37 years) and 10th grade (15.36 years) students. Adolescents were similar to their mutual friends and network associates (identified using Social Cognitive Mapping) in religiosity, and the religiosity of both friends and network associates added to male adolescents' self‐religiosity in predicting antisocial behavior; these effects were not present for girls. Peers may associate with others similar to themselves in religiosity and these associations may partially explain why religious boys exhibit low levels of aggressive behavior.     

Popularity of Indonesian Adolescents: Do the Findings from the USA Generalize to a Muslim Majority Developing Country?

This study investigated whether the pattern of behavior associated with popularity in the USA is also found in Indonesia. Participants were 452 7th (13 years) and 10th grade (16 years) Muslim students from West Java, Indonesia. Data were obtained from adolescents, peers, and teachers. Social preference and popularity were positively associated with prosocial behavior and number of mutual friends. Whereas social preference was positively associated with academic achievement and negatively associated with aggression, popularity was positively associated with aggression and tobacco use. These patterns of association are similar to those found in the United States. Indonesian society is highly hierarchical and popularity structures may build upon these stratifications.     

Peer Relationships and Indonesian Muslim Adolescents' Religiosity and Religious Coping: Selection and Influence

The religious similarity of adolescents and their friends can arise from selection or influence. Prior studies were limited because of confounds that arose from the ethnic and religious heterogeneity of the samples and the use of cross-sectional designs. SIENA was used in this two-year longitudinal study of 825 Indonesian Muslim high school students (445 girls; mean age = 16.5 years) to assess peer selection and influence as these pertained to religiosity and religious coping. The analyses yielded significant influence but not selection effects for both religiosity and religious coping. This study is an important methodological advance over prior research and although limited by correlational data, nevertheless, provides evidence that adolescents influence their peers' religiousness.     

Religiosity and Effortful Control as Predictors of Indonesian Adolescents’ Tobacco and Alcohol Use: Moderation and Mediation

Moderation and mediation models of religiosity and effortful control as predictors of tobacco and alcohol use were tested in this 2‐year longitudinal study of 563 16‐year‐old Muslim Indonesian adolescents. Adolescents reported their effortful control, religiosity, and tobacco and alcohol use and peers provided reports of adolescents’ effortful control. Although both moderation and mediation effects emerged when predicting Year 2 substance use, predictions of change from Year 1 to Year 2 substance use yielded effects of moderation for peer‐ but not self‐reported effortful control for boys; no mediation effects emerged. These findings provide evidence of interconnections between effortful control and religiosity as predictors of substance use and suggest the need for further longitudinal studies that compare moderation and mediation models.
