Outcome of group cognitive-behavior therapy for bulimia nervosa: the role of core beliefs.
It is hypothesized that individuals who benefit less from CBT will be those who have more pathological core beliefs (unconditional beliefs, unrelated to food, shape and weight). Twenty bulimic women were treated using 12 sessions of conventional group CBT. Eating behavior and attitudes were assessed pre- and posttreatment. Core beliefs were assessed at the beginning of the programme, and were used as predictors of change across treatment (once any effect of pretreatment psychopathology was taken into account). Group CBT was effective, with reductions of over 50% in bulimic symptoms. Outcome on most indices was associated with pretreatment levels of pathological core beliefs. Possible reasons for these findings are discussed.
