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.

同伴关系和印度尼西亚穆斯林青少年的宗教信仰和宗教应对：选择和影响

青少年及其朋友的宗教相似性可能来自选择或影响。由于样本的种族和宗教异质性以及横断面设计的使用引起的混淆，先前的研究受到限制。在这项为期两年的纵向研究中，SIENA 被用于对 825 名印度尼西亚穆斯林高中生（445 名女生；平均年龄 = 16.5 岁）进行评估，以评估同伴选择和影响，因为这些与宗教信仰和宗教应对有关。这些分析对宗教信仰和宗教应对产生了重大影响，但没有产生选择效应。这项研究在方法论上比之前的研究取得了重要进展，尽管受到相关数据的限制，但它提供了青少年影响同龄人宗教信仰的证据。
