About this trial
To examine the efficacy of a Transtheoretical Model (TTM)-based intervention in improving weight management behaviors.
1. To identify if the student age, body mass index (BMI) and socioeconomic status can predict WMB. 2. To investigate the difference in students' WMB between groups of grade, liven arrangement, socioeconomic class, and BMI.

Transtheoretical Model (TTM)-Based Behavioral Intervention for Weight Management
BehavioralThis is a non-pharmacological, behavioral intervention designed to improve weight management behaviors among high school female students. It is based on the Transtheoretical Model of behavior change and consists of structured, stage-matched educational and counseling sessions. The intervention includes guidance on healthy dietary practices, promotion of regular physical activity, goal setting, self-monitoring techniques, and motivational strategies tailored to each participant's readiness to change.
Treatment groups
Trial outcomes
Primary outcomes
Change in Weight Management Behavior Scores Measured by TTM-Based Questionnaires
Change in Weight Management Behavior Scores Measured by TTM-Based Questionnaires: Weight Control Decisional Balance Scale (WCDBS): 20-item scale with scores ranging from -40 to +40. Higher positive scores indicate more favorable attitudes toward healthy weight management behaviors. Weight Control Processes of Change Scale (WCPOCS): 48-item scale with scores ranging from 48 to 240. Higher scores indicate greater engagement in healthy weight management behavior change processes. Stages of Change for Weight Control Scale (SCWCS): categorizes participants into precontemplation, contemplation, preparation, action, and maintenance stages. Higher stages indicate greater readiness for healthy weight management behavior change. The outcome will be reported as mean score changes and stage distribution differences between intervention and control groups.
