abstract
- Body dissatisfaction is one of the strongest predictors of eating disorder relapse. Yet, a dearth of research exists on factors that facilitate change in body dissatisfaction following treatment focused on symptom interruption. Recent research points to the role of weight control beliefs in predicting outcomes in patients with eating disorders. The primary objective of this research was therefore twofold: 1) To investigate the impact of group cognitive behavioural therapy (GCBT) on weight control beliefs and body dissatisfaction and 2) to examine the influence of weight control beliefs on body dissatisfaction over time. Participants were 50 adults with a recent eating disorder diagnosis who completed 10 sessions of GCBT for body image following GCBT for eating disorders. All participants completed the Eating Disorder Inventory and Weight Control Beliefs Questionnaire at baseline and post-treatment. Body dissatisfaction and weight control beliefs improved from pre- to post-treatment. Hierarchical linear regression analyses revealed that increases in lifestyle control beliefs, a subtype of weight control beliefs, predicted decreases in body dissatisfaction. Results underscore the utility of fostering healthy weight control beliefs to cultivate a positive body image in patients navigating the eating disorder recovery process.
