Abstract
- <bold>Background: </bold>Non-suicidal self-injury (NSSI) and suicide attempts are related, but distinct behaviors. The primary aim of the current study was to identify factors that distinguish those with different lifetime histories of self-injury. A secondary aim was to test whether lifetime history of self-injury at age 26 predicted current suicide ideation at age 32.<bold>Methods: </bold>Participants were 26 year olds from a large birth cohort with a lifetime history of no self-injury (n = 466), a lifetime history of NSSI (n = 191), or a lifetime history of NSSI and a suicide attempt (NSSI+SA; n = 52). They were compared on a history of psychiatric disorders, 12-month suicide ideation, lifetime history of childhood sexual abuse, and lifetime exposure to suicide.<bold>Results: </bold>An anxiety disorder, a substance dependence disorder, suicide ideation, and a history of childhood sexual abuse distinguished the NSSI+SA and NSSI only groups. Longitudinal results demonstrated that a history of NSSI predicted future suicide ideation after adjusting for other selected risk factors.<bold>Limitations: </bold>The majority of analyses are cross-sectional which limits inferences about causality. The retrospective self-report for lifetime behavior could be subject to reporting biases.<bold>Conclusions: </bold>Adults with a history of NSSI and adults with a history of NSSI and a suicide attempt are clinically distinct groups that are both at risk of future suicide ideation. Identifying and treating NSSI could be a key preventive factor in reducing subsequent suicide risk. [ABSTRACT FROM AUTHOR]
