Efficacy of a Stage-Matched Intervention Based on The Transtheoretical Model of Change in Dietary Fat Reduction

Efficacy of a Stage-Matched Intervention Based on The Transtheoretical Model of Change in Dietary Fat Reduction Among Female High School Students: A Randomized Controlled Trial

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.

Study Overview

• Status: Completed
• Conditions: Dietary Fat Reduction
• Intervention / Treatment: Behavioral: Stage-matched interventions

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Precontemplation, Contemplation, Preparation, Action, and Maintenance-based intervention; The intervention that would consider the Processes of Change that people use when they would be in the Precontemplation Stage of Change.	Behavioral: Stage-matched interventions; 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.
Experimental: Contemplation-based intervention; The intervention that would consider the Processes of Change that people use when they would be in the Contemplation Stage of Change.

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.
Experimental: Preparation-based intervention; The intervention that would consider the Processes of Change that people use when they would be in the Preparation Stage of Change.	Behavioral: Stage-matched interventions; 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.
Experimental: Action-based intervention; The intervention that would consider the Processes of Change that people use when they would be in the Action Stage of Change.	Behavioral: Stage-matched interventions; 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.
Experimental: Maintenance-based intervention; The intervention that would consider the Processes of Change that people use when they would be in the Maintenance Stage of Change.	Behavioral: Stage-matched interventions; 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.
