Educational Program by Using Behavior Change Wheel Model

Routine health education

The BCW model includes three layers: the behavior system, intervention functions, and policy categories, with the last not being applied in this study. The research was structured into four phases: assessment, planning, implementation, and evaluation.

Phases of the Study Assessment Phase: Researchers introduced themselves to parents and adolescents through personal interviews, explaining the study's significance. They collected demographic data in the forensic and toxicology department, using various tools to assess adolescents' behaviors before the educational program.

Planning Phase: A tailored BCW model encompassed a wide range of educational interventions. The content

This tool assesses adolescents' behavior changes related to substance abuse using the COM-B model (Capability, Opportunity, Motivation). It consists of 15 items measuring adolescents' feelings and experiences related to substance use. Scoring ranges from 0 to 30, with a cutoff of 60% (18 points) indicating satisfactory behavior change. Validity and reliability were established through expert review and a Cronbach's alpha greater than 0.80.

This checklist evaluates adolescents' knowledge and practices regarding substance abuse through two parts: knowledge assessment with 10 items and reported practices across nine intervention functions. Each section uses varying scoring systems with cutoff points at 60% for satisfactory performance. The tool's validity and reliability were confirmed by experts and a Cronbach's alpha above 0.81.

The AADIS is a standardized self-report tool measuring adolescents' frequency of alcohol and drug use over the past month. It includes 14 items, where higher scores indicate greater substance use involvement. A cutoff score of 37 is used to identify potential substance use disorders based on DSM-IV criteria. Interpretations range from no use (0) to possible substance use disorder (37 or higher).
