This study examined differences between young people with mental illness who engage in deliberate self-harm with and without suicidal intent, as well as socio-demographic and clinical factors that are related to the increased likelihood of suicide attempt amongst self-harming young people. A total of 235 outpatients with mental illness who had engaged in deliberate self-harm were recruited from a tertiary psychiatric hospital in Singapore. Participants completed a self-report questionnaire which collected information on their socio-demographic background, self-harm history, diagnosis, depressive symptoms and childhood trauma. A total of 31.1% had reported a history of attempted suicide. Multiple logistic regression conducted found that engaging in self-harm ideation between 1 and 7 days (OR = 4.3, = 0.30), and more than 1 week (OR = 10.5, < 0.001) (versus no engagement in any self-harm ideation at all), were significantly associated with greater likelihood of attempted suicide. This study reports a relatively high prevalence rate of reported suicide attempts amongst young people with mental illness who engaged in self-harm. Identifying self-harm behaviors and treating it early could be the first step in managing potential suicidal behaviors among those who engage in self-harm.
本研究旨在探讨有自杀意念和无自杀意念的蓄意自伤年轻人之间的差异，以及与自伤年轻人自杀企图风险增加相关的社会人口统计学和临床因素。本研究共招募了 235 名来自新加坡一家三级精神病院的有蓄意自伤行为的门诊精神疾病患者。参与者完成了一份自我报告问卷，其中收集了他们的社会人口统计学背景、自伤史、诊断、抑郁症状和儿童期创伤的信息。共有 31.1%的人报告有自杀未遂史。多因素逻辑回归分析发现，在 1 至 7 天（OR = 4.3， = 0.30）和超过 1 周（OR = 10.5， < 0.001）（与根本没有任何自伤意念相比）之间有自伤意念与自杀企图的可能性更大显著相关。本研究报告了有自伤行为的精神疾病年轻人中报告的自杀未遂率相对较高。识别自伤行为并及早治疗可能是管理有自伤行为者潜在自杀行为的第一步。
