This toolkit, developed by the Massachusetts Center of Excellence on Problem Gambling Prevention, offers a step-by-step guide to conducting effective focus groups to support communities working to prevent problem gambling. It explains how focus groups—small, structured group discussions—can help practitioners gather perspectives from diverse community members, understand the root causes of problem gambling, and inform prevention strategies. The resource walks users through planning, recruiting, facilitating, and analyzing focus group discussions and includes sample questions, consent forms, and templates to support each stage of the process.
