背景资料：在9/11事件后的退伍军人中，酒精使用障碍（AUD）和创伤后应激障碍（PTSD）的共病率正在增加，情绪调节问题已被确定为这两种疾病的特征。然而，迄今为止还没有研究探讨情绪调节的个体差异如何调节PTSD症状和饮酒之间的关系。我们评估了两种核心情绪调节策略--一种是自适应的（即，认知重新评价）和一种适应不良（即，方法：共有71名9/11事件后退伍军人（12名女性，59名男性）完成了基线筛选和至少两次随访评估，超过12个月的过程中，其中包括情绪调节，PTSD症状和酒精使用的措施。一个混合的增长模型，以确定是否在PTSD症状的变化与酒精的使用随着时间的推移，这种关系是否是缓和的使用频率的情绪调节strategies.Results：在一般情况下，较高的PTSD症状显着相关，更大的酒精使用，但认知重新评估缓和这种关系。具体来说，在低认知重新评估，更大的创伤后应激障碍症状与更多的酒精使用。在高认知重新评价，有没有显着的关联PTSD症状和酒精use.Conclusions：本研究的结果表明，基线的认知重新评价的个体差异影响PTSD症状和酒精使用之间的关系。对于9/11事件后的退伍军人来说，高水平的认知重新评估可能是防止持续饮酒的保护因素。
Background: Rates of comorbid alcohol use disorder (AUD) and posttraumatic stress disorder (PTSD) are increasing among post-9/11 veterans, and emotion regulation problems have been identified as a feature of both disorders. However, no studies to date have explored how individual differences in emotion regulation may moderate the relationship between PTSD symptoms and alcohol use. We evaluated how two core emotion regulation strategies - one adaptive (i.e., cognitive reappraisal) and one maladaptive (i.e., expressive suppression) are related to PTSD symptoms and alcohol use over one-year.Methods: A total of 71 post-9/11 veterans (12 female, 59 male) completed a baseline screening and at least two follow-up assessments over the course of 12 months which included measures of emotion regulation, PTSD symptoms, and alcohol use. A mixed growth model was utilized to determine if changes in PTSD symptoms covaried with alcohol use over time and whether this relation was moderated by frequency of use of emotion regulation strategies.Results: In general, higher PTSD symptoms were significantly associated with greater alcohol use, but cognitive reappraisal moderated this relationship. Specifically, at low cognitive reappraisal, greater PTSD symptoms were associated with greater alcohol use. At high cognitive reappraisal, there was no significant association between PTSD symptoms and alcohol use.Conclusions: Findings from the present study suggest that baseline individual differences in cognitive reappraisal influence the relation between PTSD symptoms and alcohol use. For post-9/11 veterans, high levels of cognitive reappraisal may serve as a protective factor against ongoing alcohol use.
