Exploring the indirect effects of acute dissociation on capability and suicide risk: A multi-method investigation with augmented reality.

Abstract

The current study aimed to explicate the role of dissociation in the capability and suicide relationship by examining how lifetime and state-based acute dissociation contributes to capability for suicide using a multi-method approach of self-report and augmented reality (AR) laboratory tasks. Participants (N=145) were students recruited for course credit at a southern university. Participants completed self-report and laboratory AR dissociative induction tasks. Correlations and mediation analyses were conducted to test hypotheses using SPSS v. 26 and PROCESS Macro. There was a significant indirect effect on capability and suicidal ideation via acute dissociation (β=0.035, SE=0.02, 95% CI=0.001, 0.095). Additionally, there was a significant indirect effect on capability and suicide attempt(s) via dissociation (β=0.19, SE=0.10, 95% CI=0.044, 0.449). As prior theories suggest, dissociation may augment feeling disconnected from the body and may temporarily impact capability to render a suicidal act as more probable. The presence of dissociation after a painful and provocative attempt may increase capability and pain tolerance. Implications of these findings include the consideration of dissociation as a pertinent factor in the assessment and treatment of suicide and the role of AR in aiding the exploration of suicide correlates.
