This study examined the main and interactive effects of MDD and lifetime nonsuicidal self-injury (NSSI) on current suicide risk and past suicide attempts. We predicted that individuals with a history of NSSI and current MDD would be at greater suicide risk than those with either risk factor alone. An interaction between lifetime MDD and NSSI was hypothesized for past suicide attempts. 204 substance dependent inpatients completed self-report measures and a diagnostic interview. Patients with both a history of NSSI and current MDD, relative to all other groups, had the greatest suicide risk. No support was found for the lifetime MDD by NSSI interaction.
Findings suggest the relevance of both NSSI and MDD in suicide risk.
本研究考察了 MDD 和终生非自杀性自伤 (NSSI) 对当前自杀风险和既往自杀企图的主要和交互作用。我们预测,有 NSSI 病史和当前 MDD 的个体的自杀风险高于仅有单一风险因素的个体。假设终生 MDD 和 NSSI 之间存在交互作用,用于既往自杀企图。204 名物质依赖住院患者完成了自我报告量表和诊断访谈。与所有其他组相比,同时有 NSSI 和当前 MDD 病史的患者自杀风险最大。未发现终生 MDD 与 NSSI 之间存在交互作用的证据。
研究结果表明 NSSI 和 MDD 都与自杀风险相关。
