Sexual Victimization and Suicide Ideation: An Atemporal Indirect Effects Model

Suicide is a major public health concern among young adults. Moreover, college students are at elevated risk for sexual victimization, which is associated with elevated suicide risk. Nonetheless, not all college student survivors of sexual victimization think about suicide. Previous research has used the interpersonal psychological theory of suicide (IPTS) as a framework for understanding the association between interpersonal violence victimization and suicide ideation The current study aimed to replicate and extend the results of Poindexter et al. AQ1] by testing the serial indirect effects of IPTS constructs in the relationship between sexual victimization and suicide ideation among a sexually-victimized sample of college students. It was expected that depressive symptoms, thwarted belongingness, and perceived burdensomeness, in that order, would indirectly affect the association between cumulative sexual victimization history and suicide ideation in the past month.

Data were collected from 796 college students via online survey. After exclusion criteria, 236 college students who reported at least one lifetime experience of sexual victimization were included in analysis.

Results indicated that the relationship between cumulative sexual victimization and past-month suicide ideation frequency was indirectly affected by depressive symptoms, thwarted belongingness, and perceived burdensomeness, in serial.

Results indicated that the indirect effects model proposed by Poindexter et al. was significant in that more frequent lifetime sexual victimization related to more frequent past-month suicide ideation, and this relationship was strengthened indirectly by depressive symptoms, TB, and PB, in that order. Results underscore the importance of screening survivors of sexual victimization for suicide ideation and associated risk factors, specifically depressive symptoms, TB, and PB.
