Abstract

Objective

There have been few randomized clinical trials (RCTs) for adolescents with anorexia nervosa (AN). Most of these posit that involving all family members in treatment supports favorable outcomes. However, at least 2 RCTs suggest that separate parent and adolescent sessions may be just as effective as conjoint treatment. This study compared the relative efficacy of family-based treatment (FBT) and parent-focused treatment (PFT). In PFT, the therapist meets with the parents only, while a nurse monitors the patient.

Method

Participants (N = 107) aged 12 to 18 years and meeting DSM 4(th)Edition criteria for AN or partial AN were randomized to either FBT or PFT. Participants were assessed at baseline, end of treatment (EOT), and at 6 and 12 months posttreatment. Treatments comprised 18 outpatient sessions over 6 months. The primary outcome was remission, defined as ≥95% of median body mass index and Eating Disorder Examination Global Score within 1 SD of community norms.

Results

Remission was higher in PFT than in FBT at EOT (43% versus 22%; p = .016, odds ratio [OR] = 3.03, 95% CI = 1.23-7.46), but did not differ statistically at 6-month (PFT 39% versus FBT 22%; p = .053, OR = 2.48, CI = 0.989-6.22), or 12-month (PFT 37% versus FBT 29%; p = .444, OR = 1.39, 95% CI = 0.60-3.21) follow-up. Several treatment effect moderators of primary outcome were identified.

Conclusion

At EOT, PFT was more efficacious than FBT in bringing about remission in adolescents with AN. However, differences in remission rates between PFT and FBT at follow-up were not statistically significant.
