Background: High rates of substance use among college students have been associated with a wide range of detrimental consequences. Psychological inflexibility, characterized by both experiential avoidance and a disconnection with personally meaningful values, is proposed to contribute to the development and maintenance of substance misuse.
Objectives: This study explored the unique contribution of experiential avoidance and four different values dimensions (i.e., importance, consistency, effort, and intrinsic motivation) on substance use and related problems accounting for the known predictors of gender and drinking motives.
Method: Zero-inflated regression was used to analyze predictors of substance use and related problems among 233 college students.
Results: Controlling for gender and drinking motives, stronger values importance was predictive of lower rates of alcohol use problems. Less behavioral consistency with values predicted marijuana abstinence, less frequent use of marijuana, and less frequent use of illicit drugs. Although there was little evidence for a unique association between experiential avoidance and substance use or substance-related problems in this sample, coping and enhancement motives predicted alcohol use problems and illicit drug use.
Conclusion/Importance: These findings offer preliminary support for prevention and intervention efforts aimed at enhancing engagement in values activities and reducing substance use as a form of affect regulation in this population.
