Background: Previous studies indicated that perception of school experiences (i.e., teachers' psychological support and perceived peer climate) is associated with nonsuicidal self-injury (NSSI) behaviors among adolescents. Aims: The purpose of the current study was to explore whether depression symptoms mediate the relationship between sense of loneliness in school and NSSI behaviors among adolescents. Method: The sample included high-school students (N = 306; 51.6% girls) who completed surveys assessing their subjective sense of loneliness (feeling lonely, spending their time alone in school, and reporting a small number of friends), depression symptoms, and NSSI behaviors. Results: Multiple-group structural equation modeling, stratified by gender, supported the hypothesized model. Sense of loneliness was associated with depression symptoms, which in turn were associated with NSSI. Positive school attitudes were associated with depression symptoms only for girls. Results were robust when controlling for the relationships with parents. Limitations: The study is based on cross-sectional data, which limits the ability to make causal conclusions, and the instruments are based on self-report scales. Conclusion: Mental health professional are advised to note the significant role of subjective sense of loneliness in school as a possible risk factor for depression symptoms, which may be associated with NSSI behaviors.

抑郁症状作为青少年在学校的孤独感和非自杀性自伤行为之间的中介。

背景：先前的研究表明，对学校经历的感知（即教师的心理支持和感知的同伴氛围）与青少年的非自杀性自伤 (NSSI) 行为有关。目的：本研究的目的是探讨抑郁症状是否在学校孤独感与青少年 NSSI 行为之间起中介作用。方法：样本包括完成调查的高中生（N = 306；51.6% 女孩），他们评估了他们的主观孤独感（感到孤独、独自一人在学校的时间和报告少数朋友）、抑郁症状、和 NSSI 行为。结果：按性别分层的多组结构方程模型支持假设模型。孤独感与抑郁症状有关，这反过来又与 NSSI 相关联。积极的学校态度仅与女孩的抑郁症状有关。当控制与父母的关系时，结果是稳健的。局限性：该研究基于横截面数据，这限制了做出因果结论的能力，并且工具基于自我报告量表。结论：建议心理健康专业人士注意学校的主观孤独感作为抑郁症状可能的危险因素的重要作用，这可能与 NSSI 行为有关。这限制了做出因果结论的能力，并且这些工具基于自我报告量表。结论：建议心理健康专业人士注意学校的主观孤独感作为抑郁症状可能的危险因素的重要作用，这可能与 NSSI 行为有关。这限制了做出因果结论的能力，并且这些工具基于自我报告量表。结论：建议心理健康专业人士注意学校的主观孤独感作为抑郁症状可能的危险因素的重要作用，这可能与 NSSI 行为有关。
