Trauma exposure is linked to heavy drinking and drug use among college students. Extant research reveals positive associations between negative affect lability and both trauma exposure and alcohol use. This study aimed to extend past research by using daily diary methods to test whether (a) individuals with (versus without) trauma exposure experience greater negative and positive affect lability, (b) negative and positive affect lability are associated with heavy drinking and drug use, and (c) negative and positive affect lability mediate the relations between trauma exposure and heavy drinking and drug use. Participants were 1640 college students (M age=19.2, 54% female, 80% European American) who provided daily diary data for 30days via online surveys. Daily diaries assessed negative and positive affect and substance use (i.e., percent days of heavy drinking, percent days of drug use, total number of drugs used). Individuals with (versus without) a history of trauma exposure demonstrated higher levels of negative and positive affect lability. Negative, but not positive, affect lability was associated with percent days of heavy drinking, percent days of drug use, and total number of drugs used, and mediated the associations between trauma exposure and heavy drinking and drug use outcomes. Findings provide support for the underlying role of negative affect lability in the relations between trauma exposure and heavy drinking and drug use among college students, suggesting that treatments targeting negative affect lability may potentially serve to reduce heavy drinking and drug use among trauma-exposed college students.
创伤暴露与大学生酗酒和吸毒有关。现有研究表明，负性情绪波动与创伤暴露和酒精使用之间存在正相关关系。本研究旨在通过使用日常日记法来扩展以往的研究，以测试以下几点：（a）有（无）创伤暴露的个体是否经历更大的负性和正性情绪波动；（b）负性和正性情绪波动是否与酗酒和吸毒有关；（c）负性和正性情绪波动是否在创伤暴露与酗酒和吸毒之间起中介作用。研究对象为 1640 名大学生（平均年龄为 19.2 岁，54%为女性，80%为欧洲裔美国人），他们通过在线调查在 30 天内提供了日常日记数据。日常日记评估了负性和正性情绪以及物质使用情况（即，重度饮酒的天数百分比、使用毒品的天数百分比、使用毒品的总数量）。有（无）创伤暴露史的个体表现出更高水平的负性和正性情绪波动。负性情绪波动，但不是正性情绪波动，与重度饮酒的天数百分比、使用毒品的天数百分比和使用毒品的总数量有关，并在创伤暴露与重度饮酒和药物使用结果之间起中介作用。研究结果为创伤暴露与大学生重度饮酒和药物使用之间的负性情绪波动的潜在作用提供了支持，表明针对负性情绪波动的治疗可能有助于减少创伤暴露的大学生中的重度饮酒和药物使用。
