Early response as a predictor of success in guided self-help treatment for bulimic disorders
About this resource
The aims of this study were to investigate the number of sessions and time required for a clinical meaningful symptomatic change with a guided self-help treatment and to assess the predictive value of early response and other potential predictors of end-of-treatment clinical status. Participants were 42 patients with a diagnosis of bulimia nervosa or ED not otherwise specified. Survival analyses (Kaplan-Meier) were performed to estimate the median time required to attain a 51% reduction in bulimic symptoms. Logistic regression was used to assess predictors of symptom remission. Results showed that the median time to achieve a 51% reduction in binge and purge frequencies was 3.68 and 3.77, respectively. This change occurred at session 3 for 50% of the participants. Early response was the most significant predictor of binge eating remission. No pre-treatment predictors of time to achieve early response were found. These results have implications for allocating treatment resources in a stepped-care intervention model.
