The present investigation examined the mediating role of distress tolerance in the association between impulsivity and alcohol use coping motives among trauma-exposed individuals. Participants were 86 adults (64.3% women; M(age) = 23.4, SD = 9.3) who met the DSM-IV-TR posttraumatic stress disorder (PTSD) criterion A for at least one traumatic life event and endorsed alcohol use in the past month. Distress tolerance at least partially mediated the association between impulsivity and alcohol use coping motives, after controlling for the variance explained by PTSD symptom severity and alcohol use problems. Clinical implications and future directions related to this line of inquiry are presented and discussed.
本研究考察了痛苦耐受力在创伤暴露个体的冲动性与饮酒应对动机之间的关联中所起的中介作用。参与者为86名成年人（64.3%为女性；年龄均值M = 23.4，标准差SD = 9.3），他们至少经历过一次创伤性生活事件，符合《精神疾病诊断与统计手册第四版修订版》（DSM-IV-TR）创伤后应激障碍（PTSD）的A类标准，且在过去一个月内有饮酒行为。在控制了PTSD症状严重程度和饮酒问题所解释的方差后，痛苦耐受力至少部分中介了冲动性与饮酒应对动机之间的关联。文中呈现并讨论了与此研究方向相关的临床意义和未来方向。
