Analysis of between-diagnoses differences in music-based affect regulatory strategies in adults with mental health and substance use conditions: Implications for transdiagnostic application

According to the Stress Vulnerability Model, affect regulation is crucial to manage stressors and promote recovery for adults with mental health conditions. Education regarding music-based affect regulation can be delivered in group formats using a transdiagnostic approach to increase access to services and vicarious learning. Therefore, the purpose of this study was to determine if there were between-diagnosis and between-substance differences in music-based affect regulation via the Brief Music in Mood Regulation Scale (B-MMR) and Healthy-Unhealthy Music Scale (HUMS) subscales in adults with mental health and substance use conditions. Adults with mental health (n = 147) and substance use (n = 221) conditions completed the B-MMR and HUMS. Analyses of variance were conducted with participants’ mental health diagnosis or primary substance as independent variables and the B-MMR and HUMS subscales as dependent variables. There were only significant between-substance differences in revival and discharge subscales, with participants addicted to heroin having higher mean scores than participants addicted to alcohol. No other result was significant. Due to an overall lack of between-group differences in diagnoses and substances, transdiagnostic theory has applications for educating adults with mental health and substance use conditions about music-based affect regulation in group formats.
