Social anxiety and risky Marijuana use The role of underutilization of protective behavioral strategies.
Social anxiety is a common mental health problem that increases the risk of experiencing cannabis-related problems. In fact, social anxiety more than quadruples the risk of developing cannabis use disorder, yet it is inconsistently related to more cannabis use. Inconsistent findings may be due to lack of attention to protective behavioral strategies (PBS) among socially anxious cannabis users. PBS are cognitive-behavioral strategies to reduce cannabis use and related problems. Yet socially anxious persons may be less likely to use PBS for a variety of reasons (e.g., fear of negative evaluation for engaging in behaviors to reduce use), leading to heavier or more frequent use and related problems. The current study examined the mediating role of PBS in the relationships of social anxiety with past-month cannabis use and related problems among current (past-month) cannabis users (N 102). Social anxiety was significantly positively related to past-month cannabis problems, but not directly related to cannabis use. Social anxiety was significantly negatively related to PBS. Social anxiety was indirectly (via PBS) related to more frequent use, greater peak use, and more cannabis problems. Serial mediation analyses indicated that social anxiety was indirectly related to more cannabis problems via the serial effects of PBS and cannabis use variables. Findings suggest that socially anxious persons may be vulnerable to heavier cannabis use and more cannabis problems due to PBS underutilization. Treatment implications are discussed.
