Pdf Summary
This study, conducted by Lin, Matlack, and Ansell at Penn State University, investigated the interplay between psychoticism, emotion dysregulation, and cannabis use outcomes over six months among young adult recreational cannabis users. Supported by the National Institute on Drug Abuse, the research involved 215 participants aged 18–30 who used cannabis occasionally or frequently.<br /><br />Using validated measures—such as the Difficulties in Emotion Regulation Scale (DERS), the Personality Inventory for DSM-5 (PID-5), and the Brief Marijuana Consequences Questionnaire (B-MACQ)—the study examined how personality traits related to psychoticism and emotion regulation difficulties predicted cannabis-related problems. Linear regression analyses controlled for demographic variables and baseline cannabis consequences.<br /><br />Key findings include that among individuals with low psychoticism (scores below 1.23), lower emotion dysregulation correlated with fewer cannabis-related problems, while higher emotion dysregulation predicted more problems. A similar moderating effect of emotion dysregulation was observed for the PID-5 facet of unusual beliefs and experiences (threshold 0.59). In contrast, for individuals with high psychoticism or unusual beliefs, varying levels of emotion dysregulation did not significantly alter cannabis-related problem outcomes—these individuals demonstrated elevated problems regardless. Furthermore, higher levels of perceptual dysregulation and eccentricity were independently associated with greater cannabis-related consequences, but emotion dysregulation did not moderate these relationships.<br /><br />The results underscore psychoticism as a dimensional personality trait conferring risk for problematic cannabis use, and suggest that emotion dysregulation exacerbates this risk particularly in those with lower psychoticism traits. The study highlights the importance of incorporating transdiagnostic personality and emotion regulation factors in the assessment and treatment of cannabis-related problems. Future research is encouraged to develop interventions addressing these dimensions to support at-risk young adults exhibiting subclinical psychotic traits and emotion regulation difficulties.
