Brief Summary

To examine the efficacy of a Transtheoretical Model (TTM)-based intervention in improving weight management behaviors.

1. 1.To identify if the student age, body mass index (BMI) and socioeconomic status can predict WMB.
2. 2.To investigate the difference in students' WMB between groups of grade, liven arrangement, socioeconomic class, and BMI.

Outcome Measures

Primary Outcomes (1)

• 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.

Study Arms (2)

Experimental (Intervention Group)

EXPERIMENTAL

Participants in this arm will receive a structured behavioral intervention based on the Transtheoretical Model of behavior change. The program includes stage-matched educational and counseling sessions designed to improve weight management behaviors. Components include guidance on healthy eating, promotion of physical activity, goal setting, self-monitoring, and motivation enhancement according to each participant's readiness for change. The intervention is non-pharmacological and has no known side effects.

Behavioral: Transtheoretical Model (TTM)-Based Behavioral Intervention for Weight Management

Control (No Intervention)

NO INTERVENTION

Participants in this arm will receive routine school-based health education only. This includes general information about healthy lifestyle practices such as balanced nutrition and physical activity. No structured behavioral change program or stage-based intervention will be provided.

Interventions

Transtheoretical Model (TTM)-Based Behavioral Intervention for Weight Management BEHAVIORAL

This 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.
