Tóm tắt	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 Health-Promoting Lifestyle Profile II (HPLP-II) is a 52-item self-report instrument developed by Walker, Sechrist, and Pender in 1987 to assess and measure health-promoting behaviors across multiple life domains. Based on Pender's Health Promotion Model, the HPLP-II evaluates six dimensions of positive health behavior: Health Responsibility, Physical Activity, Nutrition, Spiritual Growth, Interpersonal Relations, and Stress Management. Unlike disease-focused instruments, the HPLP-II captures a comprehensive picture of wellness-oriented lifestyle practices. It is widely used in nursing research, health promotion program evaluation, population health assessment, and clinical practice to identify health strengths and areas for behavior change counseling.
