概要	The Transtheoretical Model (TTM), also called the Stages of Change model, is a framework developed by James Prochaska and Carlo DiClemente in 1983 to understand how people modify problematic behaviors and adopt healthier ones. The central premise is that behavior change is not an all-or-nothing event but a process that unfolds over time through distinct, recognizable stages: Precontemplation (not considering change), Contemplation (thinking about change), Preparation (planning to change), Action (actively modifying behavior), and Maintenance (sustaining change). The Stages of Change questionnaire assesses which stage an individual occupies, enabling clinicians and researchers to match interventions to readiness level. This framework is widely applied in smoking cessation, substance abuse treatment, diet change, exercise adoption, and mental health treatment.	The Behavioral Regulation in Exercise Questionnaire—3 (BREQ-3) is a 24-item measure developed by Wilson and colleagues (2012) to assess the type and quality of motivation underlying exercise behavior. Grounded in Self-Determination Theory, the BREQ-3 measures six regulation types positioned on a continuum from amotivation (no intention to exercise) through external regulation (exercising for external rewards or pressure), introjected regulation (exercising due to guilt or internal pressure), identified regulation (exercising because you value the benefits), integrated regulation (exercising because it aligns with your identity and values), and intrinsic motivation (exercising for enjoyment and interest). The BREQ-3 is widely used in exercise science, sports psychology, and health behavior research to understand why people exercise and to predict long-term exercise adherence.
