Trial on Three Eating Disorders Group Treatment
Study Details
Study Description
Brief Summary
This trial aims at comparing three group treatments designed for eating disorders: a Cognitive-dissonance, a Mindfulness and a Person-centered based programs. Women with eating disorders will be recruited and randomized to one of the three programs. Participants will complete a pretest, a posttest, a 3-months follow-up and a 1-year follow-up. This trial aims to compare the programs to analyze the specific dimensions upon which each program acts. The investigators therefore made hypotheses according to the programs' theory: participants in the Cognitive-dissonance based program should experience a greater decrease in eating disorders symptoms, thin-ideal internalization and body dissatisfaction and a greater improvement in quality of life than other participants. Participants in the Mindfulness-based program should show a greater improvement in negative affect and in equanimity than other participants. Participants in the Person-Centered based program should report a greater increase in congruence than other participants.
