title: Behaviorally-indexed distress tolerance and suicidality.
abstract: Research indicates that distress tolerance exhibits a complicated relationship with risk factors for suicidal behavior. Specifically, low self-reported distress tolerance has been linked to perceived burdensomeness and thwarted belongingness. Contrastingly, high self-reported distress tolerance has been linked to the acquired capability for suicide. Given the frequently discrepant findings between self-report and behavioral indices of distress tolerance, we sought to expand upon prior findings by testing these relationships utilizing a behavioral measure of distress tolerance. Additionally, in an effort to further clarify the role of distress tolerance relative to painful and/or provocative experiences in the acquired capability, we examined whether distress tolerance serves as a moderator. Results revealed no significant associations between distress tolerance and burdensomeness or belongingness; however, distress tolerance was positively associated with the acquired capability. Furthermore, the interaction of distress tolerance and painful and/or provocative experiences significantly predicted the acquired capability, with the strength of the association increasing at higher levels of distress tolerance. Results highlight the potential importance of perceived versus actual ability to tolerate distress with respect to suicidal desire. In contrast, the results reflect the importance of actual persistence in the acquired capability.
