About this study

Substance abuse is of great concern to health issues worldwide, that typically initiated during adolescence, and it usually increases the likelihood of future physical, behavioral, social, and health issues. The Behavior Change Wheel can used as a practical and effective way of delivering real behavior change among adolescent's substance abuser. The aim of study was to effect of educational program by using behavior change wheel model on knowledge, behavior and involvement in substance abuse among adolescents. The design of this study was a quasi-experimental design and the target population for the study was adolescents. Total 226 samples were selected using the convenient sampling technique. Tool of the study consists of four tools which includes Tool I: An interviewing structured questionnaire sheet, Tool (II): Adolescents' behavior changes related to COM-B part of Behavior Change Wheel assessment form: Tool (III): Reported assessment checklist of the second part of Behavior Change Wheel, and Tool IV: Adolescent Alcohol and Drug Involvement Scale (AADIS).

Treatment and study plan

Educational Program by Using Behavior Change Wheel Model

Behavioral

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

routine health education

Behavioral

Participants in the control group received the routine health education and advice from nurses and healthcare providers working in the study settings

Primary outcomes

  1. Adolescents' behavior changes related to COM-B part of Behavior Change Wheel assessment form

    Time frame: 3 months

    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.

  2. Reported assessment checklist of the second layer of Behavior Change Wheel

    Time frame: 3 months

    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.

  3. Adolescent Alcohol and Drug Involvement Scale (AADIS)

    Time frame: 3 Months

    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).
