The co-occurrence of posttraumatic stress disorder (PTSD) and substance use disorders (SUDs) is associated with greater risk for suicidal behavior than either disorder alone. Research highlights the relevance of PTSD symptoms in particular to suicide risk within this population. Research has also provided support for an association between distress tolerance (DT) and both PTSD symptoms and suicidal behavior. This study examined the role of DT in the relationship between PTSD symptom severity and suicidal behavior in a sample of 164 SUD inpatients with a history of Criterion A traumatic exposure. Results indicated that DT moderated the relationship between PTSD symptoms (overall, re-experiencing, and hyperarousal) and medically attended suicide attempts, with the magnitude of the relationship increasing at higher levels of DT.
创伤后应激障碍（PTSD）和物质使用障碍（SUD）共病与自杀行为的风险高于任一单独的障碍。研究强调了 PTSD 症状在该人群的自杀风险中的相关性。研究还支持痛苦耐受力（DT）与 PTSD 症状和自杀行为之间的关联。本研究在 164 名有创伤暴露病史的 SUD 住院患者样本中，考察了 DT 在 PTSD 症状严重程度与自杀行为之间关系中的作用。结果表明，DT 调节了 PTSD 症状（总体、再体验和过度警觉）与经医疗处理的自杀企图之间的关系，DT 水平越高，关系的强度越大。
