Brief summary

This study aims to examine the efficacy of a Stage-Matched Intervention based on The Transtheoretical Model of Change in dietary fat reduction among female high school students.

Detailed description

This study aims to examine the efficacy of a Stage-Matched Intervention based on The Transtheoretical Model of Change in dietary fat reduction among female high school students. The study intervention will be designed based on each Stage of Change of the Transtheoretical Model of Change in that participants in each Stage of Change will receive the intervention that matches the Stage of Change they would be in. A 12-week interval would be considered between administering the intervention and posttest 1 and the same interval would be used between posttest 1 and posttest 2.
