Étude-pilote portant sur une intervention de groupe auprès de femmes souffrant d’hyperphagie boulimique et l’évaluation de ses effets potentiels
This study focuses on a group intervention for binge eating disorder (BED), by measuring its potential effects on the quality of life related to weight, frequency and severity of binge episodes, depressive symptoms, body dissatisfaction and body weight, and documenting the degree of acceptance of the intervention by the participants. Thus, 11 overweight women that met the BED diagnostic criteria were recruited from spring 2012 to winter 2013, in Montreal. The program includes eight weekly sessions based on Cognitive Behavioral Therapy provided by a nutritionist and a psychotherapist. Quality of life related to weight (Impact of Weight on Quality of Life), binge eating frequency (recall of the last seven days), binge eating severity (Binge Eating Scale), depression (Beck Inventory for depression), body dissatisfaction (Body Shape Questionnaire) and body weight were measured before and after the intervention. Then, a questionnaire to assess the acceptance by the participants was submitted at the end of the program. The rate of participation was also collected. The results showed that our program has resulted in significant improvements in the overall quality of life score related to weight of 8.4 ± 13.3, and in terms of self-esteem and work. We also observed a decrease in binge eating frequency by 2.1 ± 2.1 days as well as in binge eating severity, depressive symptoms and body dissatisfaction whose scores decreased by 10.9 ± 7.7, 8.3 ± 5.7 and 32.8 ± 17.1 respectively. However, there was no significant difference in weight at the end of the intervention. Also, the program was well accepted by the participants with a participation rate of 93.8%. Satisfaction and relevance of the program scored respectively 4,6 and 4,8 out of 5. These data suggest that the group intervention seems to be a promising method to improve the symptoms and consequences of HB, except for weight.
