In this study, EDE-Q scores were assessed for inclusion criteria during enrollment. Additionally, changes in EDE-Q scores are assessed at post-test and follow-up to assess treatment effect.

Interventions

ACT based eating disorder prevention program 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.
