Weight loss after dieting with behavioral modification for obesity: the predicting efficiency of some psychometric data.

The aim of the study was to identify the predicting efficiency of some psychometric data on weight loss after behavior modification in moderately obese patients. A group of patients on a weight loss program with a moderately hypoenergetic diet plus behavior modification therapy for 24 weeks completed the Eating Inventory (EI), the Eating Disorder Inventory (EDI), the Body Shape Questionnaire (BSQ) and the Body Attitude Questionnaire (BAQ). Correlations between the pre-diet and post-treatment scores were evaluated by stepwise regression analysis. The weight loss percentage was positively correlated with the EDI Bulimia scale and the BAQ Feeling Fat, and negatively with the EDI Body Dissatisfaction and Interpersonal Distrust scores. These findings indicate the true effectiveness of the behavior modification technique employed to extinguish bulimic behaviors. Furthermore, it can be suggested that realistic attitudes towards own fatness with a strong motivation and a good relationship with the therapist guarantee a greater weight loss.
