The purpose of the current study was to explore whether depression symptoms mediate the relationships between perceptions of social support from three sources; namely parents, teachers, and peers, and non-suicidal self-injury (NSSI) and suicidal ideation. We also tested the interactions between the different sources of support. Focusing on the Arab-Israeli population is unique as it is an ethnic minority characterized with strong familial support, and less access to mental health services compared to the ethnic majority. Adolescents (N = 276; 65.6% girls; mean age 15.1 years) from the Arab minority in northern Israel were sampled (74% response rate). Participants were evaluated using validated scales assessing perceived social support, NSSI and suicidal ideation. Path analysis with Bayesian estimation supported the hypothesized model. Depression symptoms fully mediated the relationships between school-related social support (i.e., teachers and peers) and NSSI, and partially between parents’ support and suicidal ideation. Interactions between the social support sources were not significant, and cluster analysis indicated that each source is independently essential to understand NSSI and suicide ideation. This model emphasizes the importance of school-related factors in adolescents’ particular aspects of mental health, and suggests that one source of social support may not compensate for a lack of another.

本研究的目的是探讨抑郁症状是否介导了来自三个方面的社会支持观念之间的关系。即父母，老师和同伴，以及非自杀性自残（NSSI）和自杀意念。我们还测试了不同支持来源之间的相互作用。关注阿拉伯-以色列人口是独特的，因为它是少数族裔，具有强大的家庭支持，与多数族裔相比，获得心理保健服务的机会较少。对来自以色列北部阿拉伯少数民族的青少年（N = 276； 65.6％的女孩；平均年龄为15.1岁）进行了抽样（答复率为74％）。使用有效量表对参与者进行评估，这些量表用于评估感知的社会支持，NSSI和自杀意念。贝叶斯估计的路径分析支持假设的模型。抑郁症状完全介导了与学校有关的社会支持（即老师和同龄人）与NSSI之间的关系，部分地反映了父母的支持与自杀意念之间的关系。社会支持来源之间的相互作用并不显着，聚类分析表明，每个来源对于理解NSSI和自杀观念都是必不可少的。该模型强调了与学校有关的因素在青少年心理健康的特定方面的重要性，并表明社会支持的一种来源可能无法弥补另一种来源的不足。聚类分析表明，每个来源对于理解NSSI和自杀观念都是必不可少的。该模型强调了与学校有关的因素在青少年心理健康的特定方面的重要性，并表明社会支持的一种来源可能无法弥补另一种来源的不足。聚类分析表明，每个来源对于理解NSSI和自杀观念都是必不可少的。该模型强调了与学校有关的因素在青少年心理健康的特定方面的重要性，并表明社会支持的一种来源可能无法弥补另一种来源的不足。
