Psychological symptoms and non-suicidal self-injury (NSSI) are independently associated with suicide attempts (SA). Yet, no study has tested the interaction effects between NSSI and psychological symptoms on SA in community adolescent populations, or examined whether the interaction varies by gender. We sought to examine the interaction effects of NSSI and psychological symptoms on SA in adolescents and explore gender differences.
A school-based health survey in 3 provinces in China was conducted between 2013-2014. 14,820 students aged 10-20 years completed standard questionnaires, to record the details of various psychological symptoms, SA and NSSI.
Psychological symptoms and NSSI were independently associated with a higher likelihood of SA in both boys and girls ( < 0.001). Adolescents with psychological, conduct or social adaptation symptoms without concurrent NSSI, were twice as likely to report SA (corresponding RORs were 1.80, 1.80 and 2.16, respectively; < 0.01) than those who reported NSSI. Male adolescents with psychological, emotional, conduct or social adaptation symptoms had a higher risk of SA in the non-NSSI group than the NSSI group (corresponding RORs were 2.85, 2.26, 2.30 and 3.01 respectively; < 0.01). While in girls, only adolescents with social adaptation symptoms had a higher risk of SA in the non-NSSI group than NSSI group (corresponding RORs was 1.71, < 0.05). In the non-NSSI group, boys reporting psychological symptoms exhibited a higher likelihood of a SA than their female counterparts.
Psychological symptoms and NSSI are independently associated with an increased risk of SA in adolescents. However, to some extent, NSSI may reduce the risk of SA among individuals with psychological symptoms, especially in boys.
心理症状和非自杀性自伤（NSSI）均与自杀未遂（SA）独立相关。然而，尚无研究检验社区青少年人群中NSSI与心理症状对SA的交互作用，也未考察这种交互作用是否存在性别差异。我们旨在研究青少年中NSSI与心理症状对SA的交互作用，并探讨性别差异。
2013 - 2014年在中国3个省份开展了一项基于学校的健康调查。14820名年龄在10 - 20岁的学生完成了标准问卷，以记录各种心理症状、SA和NSSI的详细情况。
心理症状和NSSI均与男孩和女孩的SA可能性增加独立相关（<0.001）。有心理、品行或社会适应症状但无NSSI的青少年报告SA的可能性是报告有NSSI的青少年的两倍（相应的相对危险度分别为1.80、1.80和2.16；<0.01）。在非NSSI组中，有心理、情绪、品行或社会适应症状的男性青少年SA风险高于NSSI组（相应的相对危险度分别为2.85、2.26、2.30和3.01；<0.01）。而在女孩中，只有有社会适应症状的青少年在非NSSI组中的SA风险高于NSSI组（相应的相对危险度为1.71；<0.05）。在非NSSI组中，报告有心理症状的男孩比女孩更有可能出现SA。
心理症状和NSSI均与青少年SA风险增加独立相关。然而，在一定程度上，NSSI可能会降低有心理症状个体的SA风险，尤其是在男孩中。
