Evidence links positive memory characteristics and hazardous alcohol use (HAU). Relevant to the current study, evidence also indicates that trauma-exposed individuals, especially those with posttraumatic stress disorder (PTSD) symptoms, report difficulties retrieving/accessing positive memories and report HAU.
Considering this literature, we uniquely examined if and which positive memory characteristics were associated with HAU, and the potential mediating role of PTSD symptom severity in the examined relations.
A sample of 126 trauma-exposed community participants seeking mental health treatment (Mage=34.97 years) completed measures of HAU (Alcohol Use Disorders Identification Test), positive memory characteristics (Memory Experiences Questionnaire-Short Form [MEQ-SF]), and PTSD severity (PTSD Checklist for DSM-5). We conducted 8 hierarchical multiple regressions; Step 1 examined effects of gender and Step 2 added a single MEQ-SF dimension (specificity, valence, emotional intensity, sensory details, vividness, accessibility, coherence, sharing).
In Steps 1 (β=.27) and 2 (βs from .27-.28), gender was associated with HAU. In Step 2, positive memory characteristics of specificity (β=.17), sensory details (β=.17), sharing (β=.23), and valence (β=-.19) were associated with greater HAU. PTSD severity mediated relations between sensory details (β=.09, p=.048), emotional intensity (β=.12, p=.011), and sharing (β=.09, p=.036), and the extent of HAU.
Results that specificity, greater sharing, more sensory details, and higher negative valence of positive memories were associated with greater HAU offer potential points of intervention.
有证据表明积极的记忆特征与危险的酒精使用（HAU）有关。与当前研究相关的是，有证据表明，经历过创伤的个体，特别是那些有创伤后应激障碍（PTSD）症状的个体，报告说他们在检索/获取积极记忆方面有困难，并报告说有 HAU。
考虑到这一文献，我们特别研究了积极的记忆特征是否与 HAU 有关，以及 PTSD 症状严重程度在这些关系中是否存在潜在的中介作用。
一组 126 名寻求心理健康治疗的经历过创伤的社区参与者（平均年龄=34.97 岁）完成了 HAU（酒精使用障碍识别测试）、积极记忆特征（记忆体验问卷-短式 [MEQ-SF]）和 PTSD 严重程度（DSM-5 PTSD 清单）的测量。我们进行了 8 项分层多元回归；第 1 步检验了性别效应，第 2 步加入了 MEQ-SF 的一个单一维度（特异性、效价、情绪强度、感官细节、生动性、可及性、连贯性、分享）。
在第 1 步（β=.27）和第 2 步（βs 从.27-.28）中，性别与 HAU 相关。在第 2 步中，特异性（β=.17）、感官细节（β=.17）、分享（β=.23）和效价（β=-.19）等积极记忆特征与 HAU 程度较高有关。PTSD 严重程度中介了感官细节（β=.09，p=.048）、情绪强度（β=.12，p=.011）和分享（β=.09，p=.036）与 HAU 程度之间的关系。
特异性、更大的分享、更多的感官细节和更高的积极记忆负效价与更高的 HAU 有关，这为干预提供了潜在的切入点。
