Gambling behaviors among college students are a growing public health concern, with problem gambling rates significantly higher in this population than in the general public.

This study outlines the protocol for a randomized controlled trial (RCT) evaluating the efficacy of RESPONSIBLEPLAY^©, a Multi-theory Model (MTM)-based intervention designed to promote responsible gambling behaviors. Proposed Methods: The intervention integrates six MTM constructs-participatory dialogue, behavioral confidence, changes in the physical environment, emotional transformation, practice for change, and changes in the social environment-to address the initiation and sustenance of behavior change. College students aged 21 and older, scoring 3 or higher on the Problem Gambling Severity Index (PGSI), will be randomly assigned to either the MTM-based intervention group or a traditional knowledge-based intervention group. The participants will complete surveys assessing PGSI and MTM constructs at pre-test, post-test, and eight-week follow-up. This study aims to provide evidence for the efficacy of theory-driven intervention compared to a knowledge-based approach.

If successful, this protocol will establish a robust framework for mitigating gambling-related harm in vulnerable college populations, paving the way for scalable, evidence-based interventions in diverse settings. The findings will contribute to the development of public health strategies that integrate theoretical constructs with practical applications to address high-risk behaviors.
