Tóm tắt	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 CUDIT-R is a brief, 8-item self-report screening instrument developed to identify cannabis use disorder and hazardous cannabis use patterns. Introduced by Adamson and colleagues in 2010 as a revision of the original CUDIT, the CUDIT-R improves brevity and screening efficiency while maintaining strong psychometric properties. It is designed for use in primary care, addiction treatment, and public health settings to detect problematic cannabis use and inform treatment allocation decisions.
