Sibling victimization is associated with adjustment problems. Protective factors that reduce the detrimental effects of sibling victimization are unknown. We examined the mediating role of social support from family and friends in the relationship between sibling victimization and adolescents' mental health distress, self-esteem, and delinquency. A telephone survey (N = 850; 49% female) was conducted with a nationally representative sample of United States adolescents (Aged 10 to 17). Three mediation models were tested exploring (a) the unique effects of family and friend support, (b) the relative effects of each type of support, and (c) the effects of total support (family and friend support summed). The three models demonstrated partial mediation of adolescents' mental health and self-esteem. Family and total support, but not friend support, partially mediated the relationship between sibling victimization and delinquency. Findings showed that family and friend social support, in combination and sometimes uniquely, reduced the adverse effects sibling victimization associated with adolescents' mental health, self-esteem, and delinquency. Efforts aimed at promoting social support from family and friends as protective factors may reduce the risk of sibling victimization experiences for adolescent well-being difficulties.

家庭和朋友的社会支持作为青少年兄弟姐妹受害和心理健康、自尊和犯罪的中介。

兄弟姐妹受害与适应问题有关。减少兄弟姐妹受害不利影响的保护因素是未知的。我们研究了来自家人和朋友的社会支持在兄弟姐妹受害与青少年心理健康困扰、自尊和犯罪之间的关系中的中介作用。电话调查（N = 850；49% 为女性）是对美国青少年（10 至 17 岁）的全国代表性样本进行的。测试了三种中介模型，探索 (a) 家庭和朋友支持的独特影响，(b) 每种类型支持的相对影响，以及 (c) 总支持的影响（家庭和朋友支持的总和）。这三个模型证明了青少年心理健康和自尊的部分中介作用。家庭和全面支持，但不是朋友支持，部分调节了兄弟姐妹受害和犯罪之间的关系。研究结果表明，家人和朋友的社会支持相结合，有时甚至是独特的，减少了与青少年心理健康、自尊和犯罪相关的兄弟姐妹受害的不利影响。旨在促进家庭和朋友的社会支持作为保护因素的努力可能会降低青少年福祉困难导致兄弟姐妹受害经历的风险。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。自尊心和过失。旨在促进家庭和朋友的社会支持作为保护因素的努力可能会降低青少年福祉困难导致兄弟姐妹受害经历的风险。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。自尊心和过失。旨在促进家庭和朋友的社会支持作为保护因素的努力可能会降低青少年福祉困难导致兄弟姐妹受害经历的风险。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。
