ABSTRACT
OBJECTIVE:
Enhanced cognitive behavior therapy (CBT-E) is a transdiagnostic treatment suitable for the full range of eating disorders (EDs). Although the effectiveness of CBT(-E) is clear, it is not being used as widely in clinical practice as guidelines recommend. The aim of the present study was to compare the effectiveness of CBT-E with treatment as usual (TAU), which was largely based on CBT principles.METHOD:
We conducted a randomized controlled trial on a total of 143 adult patients with an ED who received either CBT-E or TAU. The primary outcome was recovery from the ED. Secondary outcome measures were levels of ED psychopathology, anxiety, and depressive symptoms. Self-esteem, perfectionism, and interpersonal problems were repeatedly measured to examine possible moderating effects. We explored differences in duration and intensity between conditions.RESULTS:
After 80 weeks, there were no differences between conditions in decrease in ED psychopathology, or symptoms of anxiety and depression. However, in the first six weeks of treatment there was a larger decrease in ED psychopathology in the CBT-E condition. Moreover, when the internationally most widely used definition of recovery was applied, the recovery rate at 20 weeks of CBT-E was significantly higher (57.7%) than of TAU (36.0%). At 80 weeks, this difference was no longer significant (CBT-E 60.9%; TAU 43.6%). Furthermore, CBT-E was more effective in improving self-esteem and was also the less intensive and shorter treatment.DISCUSSION:
With broader use of CBT-E, the efficiency, accessibility and effectivity (on self-esteem) of treatment for EDs could be improved.Palavras-chave
