Objectives: 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.
Methods: 204 substance dependent inpatients completed self-report measures and a diagnostic interview.
Results: 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.
Conclusion: Findings suggest the relevance of both NSSI and MDD in suicide risk.
