摘要：Abstract Background/Objective: The evidence on efficacy of cognitive-behavioral interventions in Eating Disorders (ED) still shows inconclusive results with respect to the role of purging behaviors, more so in uncontrolled situations. Evolution of {ED} patients with and without purging behavior was studied 30 months after start of a multicomponent treatment. Method: 162 women (87 purging, 75 non-purging) treated in outpatient or hospitals + outpatient care units in Spain participated. The evaluation instruments were: BSQ, EAT-40, EDI, STAI, {BDI} and BITE. Results: At the beginning of the treatment, participants with purging behavior showed higher bulimic symptomatology, more body dissatisfaction, drive for thinness, perfectionism and ineffectiveness, anxiety and depressive symptomatology. After thirty months, intervention produced improvement in {ED} characteristics, emotional alterations and personal development variables, in both groups, but less in patients with no purging behavior. The effect of intervention was stronger in purging patients and variables with larger effect size: body dissatisfaction, bulimic symptomatology and anxiety. Conclusions: Purging behaviors must be considered in the design of these treatments with a view to prognosis.
