Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to investigate the efficacy of an online group prevention program developed for women at risk for eating disorders with randomized controlled trial.

The main questions it aims to answer are:

* Does the ACT intervention lead to a significant difference in disordered eating behaviors among individuals at risk for eating disorders?
* Does the ACT intervention lead to a significant difference in body dissatisfaction among individuals at risk for eating disorders?
* Does the ACT intervention lead to a significant difference in obsessive-compulsive and borderline personality beliefs among individuals at risk for eating disorders?
* Does body image flexibility significantly affect the impact of the ACT intervention on disordered eating behaviors?
* Do self-as-context, cognitive defusion, and present-moment awareness significantly affect the impact of the ACT intervention on disordered eating behaviors?

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

SINGLE_GROUP

There are two groups: experimental and control. Control group will receive the intervention after the follow-up assessment.

Primary Study Purpose

PREVENTION

Blinding Strategy

SINGLE

Participants

To implement participant blinding, a deception procedure was used. All participants were informed that, due to high demand, they would begin the study at different time points. They were also told that the timing of their participation would be determined randomly.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Experimental group

ACT based eating disorder prevention program. 4 sessions of 1.5 hours, held once a week

Group Type EXPERIMENTAL

ACT-ED: Acceptance and Commitment Therapy based eating disorder prevention program

Intervention Type OTHER

This intervention protocol was developed specifically for women who have body dissatisfaction and disordered eating behaviors. Based on the psychological flexibility model (hexaflex), it is designed to improve people's body image flexibility using Acceptance and Commitment Therapy techniques. Interventions related to the dimensions of the hexaflex were made during each session. The first session covers values and goal setting. The second session includes creative hopelessness, acceptance, and self-compassion. The third session covers defusion and mindfulness. The last session focuses on self-as-context exercises and the combined use of skills for committed action.
