Previous research has shown a consistent positive association between non-suicidal self-injury and depressive symptoms. However, the direction of the effects has not been examined. To understand whether non-suicidal self-injury predicts depressive symptoms or vice versa, we examined the relations between non-suicidal self-injury and depressive symptoms across three waves of self-report data collected 1 year apart from 506 Swedish adolescents (47% girls; M age = 13.21; SD = .57) who were attending 7th grade at the onset of the study. The results suggest that depressive symptoms predict increases in non-suicidal self-injury 1 year later between the first and second waves of the study. Between the second and third waves of the study depressive symptoms and non-suicidal self-injury were significantly correlated indicating co-occurrence with no direction of effect rather than depressive symptoms predicting non-suicidal self-injury or vice versa. Group comparisons revealed no differences for boys and girls. The findings help clarify the relationships between non-suicidal self-injury and depressive symptoms during middle adolescence.
先前的研究表明，非自杀性自伤与抑郁症状之间存在一致的正相关关系。然而，尚未检验这种影响的方向。为了了解非自杀性自伤是否预测抑郁症状，或者反之，我们在 3 年的时间里，使用自我报告数据，对 506 名瑞典青少年（47%为女生；平均年龄=13.21；标准差=.57）进行了 3 次随访，考察了非自杀性自伤和抑郁症状之间的关系。结果表明，抑郁症状预测了研究第 1 波和第 2 波之间 1 年后非自杀性自伤的增加。在研究的第 2 波和第 3 波之间，抑郁症状和非自杀性自伤之间存在显著相关性，表明两者同时发生，而不是抑郁症状预测非自杀性自伤，或者反之。组间比较显示，男孩和女孩之间没有差异。这些发现有助于澄清青少年中期非自杀性自伤和抑郁症状之间的关系。
