概要	The RCQ is a 12-item self-report instrument designed to assess an individual's stage of change motivation regarding substance use, particularly alcohol use. Developed by Rollnick and colleagues in 1992, it operationalizes the Transtheoretical Model of Change by measuring readiness across the precontemplation, contemplation, and action stages. The RCQ is a brief, cost-effective tool for identifying individuals who are ready to engage in behavior change and for tailoring the intensity and timing of intervention.	The DUDIT is a brief, gender-sensitive screening instrument designed to identify individuals with harmful or hazardous drug use patterns across a wide range of substances. Developed by Berman and colleagues in 2005, it serves as a primary care and public health screening tool to detect drug-related problems before they escalate to dependence or disorder. The DUDIT is freely available and has been validated in multiple languages and settings.
