Abstract: | The aim of the study was to assess the efficacy of a 12-week CBT-based pure and guided self-help among 29 patients with full and subthreshold bulimia nervosa, and binge eating disorder. In the intention-to-treat analyses, self-help had a moderately positive and sustained effect on the patients' eating problems. The patients reduced their mean number of objective bulimic episodes and purging behavior by 26% and 22% over the course of treatment. The corresponding reduction levels for the treatment completers (n=21) were 41% and 34%, respectively. As in the previous study, there were no significant differences between the pure and guided self-help mode in terms of outcome, and the results were sustained 6 months after the end of the treatment. The findings are discussed in relation to the shorter duration of the self-help, the lower rate of attrition, and the characteristics of the sample compared to the earlier trial. |
