OBJECTIVE Negative affect and affect variability figure prominently in models of addictive behaviors but are not without controversy. Negative affect variability may better capture a mechanism of behavior change in alcohol use disorder (AUD) treatment because it contains information about affect regulation, a common clinical target. The aims of this study are to examine the change in: (a) trajectory of negative affect variability, (b) association of negative affect variability and abstinence, and (c) association of negative affect variability and heavy drinking during AUD treatment. METHOD This article is a secondary analysis of data drawn from a randomized clinical trial. N = 181 participants diagnosed with Diagnostic and Statistical Manual of Mental Disorders, fifth edition AUD (Mage = 50.8, SDage = 10.6; 51.4% female) received 12 sessions of Cognitive Behavioral Coping Skills Therapy for AUD. Participants completed one daily diary prompt per day for 84 consecutive days. Each day, participants reported on negative affect and number of alcoholic drinks consumed the previous day. Time-varying effect models examined changes in negative affect variability and its associations with abstinence and heavy drinking. RESULTS Negative affect variability decreased throughout treatment. The positive association between negative affect variability and heavy drinking became nonsignificant (decoupled) midway through treatment. The inverse association between negative affect variability and daily abstinence became nonsignificant (decoupled) at approximately day 75 of 84. When mean levels of NA were added as a covariate, the effects were in the same direction but no longer statistically significant. CONCLUSION Reductions in negative affect variability may capture an important change mechanism of behavioral treatments for AUD because it contains information about affect regulation as compared with mean levels of negative affect. Negative affect variability warrants further consideration as a mechanism of behavior change. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

负面影响变异性是酒精使用障碍治疗中行为改变的潜在机制。


目的 负面情感和情感变异在成瘾行为模型中占据显着地位，但并非没有争议。负面情感变异性可以更好地捕捉酒精使用障碍（AUD）治疗中行为变化的机制，因为它包含有关情感调节（常见的临床目标）的信息。本研究的目的是检查以下方面的变化：(a) 负面情绪变异性的轨迹，(b) 负面情绪变异性与戒酒的关联，以及 (c) AUD 治疗期间负面情绪变异性与酗酒的关联。方法本文是对随机临床试验数据的二次分析。 N = 181 名被诊断患有《精神障碍诊断与统计手册》第五版 AUD 的参与者（Mage = 50.8，SDage = 10.6；51.4% 女性）接受了 12 次 AUD 认知行为应对技能治疗。参与者连续 84 天每天完成一份每日日记提示。每天，参与者都会报告前一天的负面影响和饮用的酒精饮料的数量。时变效应模型检查了负面情绪变异性的变化及其与禁欲和酗酒的关系。结果 在整个治疗过程中，负面情绪的变异性有所下降。在治疗中途，负面情绪变异性与酗酒之间的正相关性变得不显着（脱钩）。在 84 天的第 75 天左右，负面情绪变异性与每日禁欲之间的负相关变得不显着（解耦）。当 NA 的平均水平作为协变量添加时，效果方向相同，但不再具有统计显着性。 结论 负面情绪变异性的减少可能捕捉到 AUD 行为治疗的重要变化机制，因为它包含与负面情绪平均水平相比的情绪调节信息。负面影响的变异性值得进一步考虑作为行为改变的机制。 （PsycInfo 数据库记录 (c) 2024 APA，保留所有权利）。
