Abstrakt: 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 ( M age = 50.8, SD age = 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).
