Does Individualization of Psychological Treatment Result in Better Long-Term Treatment Outcome for Bulimia Nervosa Nervosa?

Abstract
Fifty patients with bulimia nervosa were randomized into either manual-based (focused) or individualized (broader) cognitive behavioral therapy. The latter was guided by logical functional analysis. A number of self-report questionnaires including the Eating disorders Examination were used for assessment at pre-, and post-treatment as well as at follow-ups, (6, and 18 months after the end of the treatment). Both conditions improved significantly at post-treatment, and the results were maintained at the six months follow-up. This presentation will focus on the longer-term outcome of the treatment conditions (i.e. 18-months follow-up) using advanced statistical analyses (Generalized Linear Mixed Models) that handle the problems with missing data more efficiently than traditional analyses such as analysis of variance. The outcome will be discussed in terms of comparable efficiency of the two conditions.
