Samenvatting	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 SADQ is a 20-item self-report instrument that measures the severity of alcohol dependence on a continuum from mild to severe. Developed by Stockwell and colleagues in 1979, it quantifies physical withdrawal symptoms, psychological dependence, and behavioral indicators of dependence to guide treatment intensity and medical management decisions. The SADQ remains a widely used assessment tool in addiction medicine and alcohol treatment settings.
