An Exploration of Differences Between Deliberate Self-Harm with and without Suicidal Intent Amongst a Clinical Sample of Young People in Singapore: A Cross-Sectional Study.

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.
