Abstract
The current study aimed at investigating whether highly impulsive binge eating disorder (BED)
patients profit more from dialectical behavioural therapy (DBT) than from cognitive behavioural
therapy (CBT) and whether this effect is maintained six-months after therapy. Therefore, 151 patients
received a 20 weeks group therapy with either CBT or DBT at Amarum, expertise centre for eating
disorders. The number of binges during the last 28 days was measured before the therapy started,
directly after the therapy was completed, and six months after the therapy was completed. In contrast
to the hypothesis, DBT was not more effective than CBT, but approximately equally effective in
reducing binges in highly impulsive patients. Both therapies maintained their positive effects six
months after therapy completion. Importantly, DBT therapy sessions were less time consuming than
CBT sessions. DBT thus reached its effect in less time. It can therefore be concluded that DBT is a
valuable alternative therapy for BED. To prove that DBT could be incorporated in standard BED
treatment, further research, taking into account the limitations of the current study, is needed.
