An Analysis of Drinking Motives in the Maintenance of Co-Occurring Obsessive-Compulsive Symptoms and Alcohol Misuse.

Objective: Despite the commonly observed co-occurrence of obsessive-compulsive symptoms (OCS) and substance use in clinical populations, few researchers have examined potential mechanisms which contribute to this relationship. This study assessed the mediating role of drinking motives in the relationship between OCS, alcohol consumption, and its resulting health risks among U.S. adults. Methods:  Adult participants ( n  = 1966; M age = 47.72, SD  = 17.91; 76.30% female; 86.10% non-Hispanic White) sourced from Research Match answered an online questionnaire containing measures related to substance use and anxiety-related symptoms. Results:  As hypothesized, there was a significant positive indirect path between OCS and both alcohol consumption and risky alcohol use through coping motives. However, there were also small indirect effects of OCS through social motivations for consumption and conformity motivations for risky alcohol use. Conclusions:  These results add evidence that coping motives play a role in OCS and alcohol misuse and highlights the need to also consider drinking motives related to social facilitation and conformity in those with co-occurring OCS and alcohol misuse.
