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.
研究表明，痛苦耐受力与自杀行为的风险因素之间存在复杂的关系。具体来说，自我报告的痛苦耐受力低与感知到的累赘感和归属感受挫有关。相反，自我报告的痛苦耐受力高与获得自杀能力有关。鉴于自我报告和痛苦耐受力的行为指标之间经常存在不一致的发现，我们试图通过使用痛苦耐受力的行为测量来扩展先前的发现。此外，为了进一步澄清痛苦耐受力相对于获得能力中的痛苦和/或挑衅性体验的作用，我们研究了痛苦耐受力是否作为一个调节因素。结果表明，痛苦耐受力与累赘感或归属感之间没有显著关联；然而，痛苦耐受力与获得能力呈正相关。此外，痛苦耐受力和痛苦和/或挑衅性体验的相互作用显著预测了获得能力，随着痛苦耐受力水平的提高，关联的强度也在增加。结果突出了感知到的与实际忍受痛苦的能力相对于自杀愿望的重要性。相比之下，结果反映了在获得能力方面实际坚持的重要性。
