Abstract

Objective

The current study examined the effectiveness of individual (IND) versus group (GRP) therapy for patients with bulimia nervosa (BN), using a manual of sequenced treatment with cognitive-behavioral therapy (CBT) followed by interpersonal psychotherapy (IPT).

Method

Eighty-six participants with BN were matched and randomized to 23 sessions of IND or GRP. Participants were measured pretreatment and posttreatment and at 1-year and 2.5-year follow-ups using both intent-to-treat and completer samples.

Results

The intent-to-treat analysis revealed that the percentage of participants recovered and remitted was equivalent between IND and GRP. Significant group differences were found between completers on binge eating and compensatory behavior with greater improvement for IND. On most measures, effect sizes were larger for IND at 1-year follow-up.

Conclusion

Sequencing CBT and IPT worked well in both IND and GRP formats. We found few outcome differences between IND as opposed to GRP. © 2005 by Wiley Periodicals, Inc.
