ABSTRACT
Objective
To examine the comparative efficacy of Family-based Treatment for Avoidant/Restrictive Food Intake Disorder (FBT-ARFID) to individual Psychoeducational Motivational Therapy (PMT) for underweight children with ARFID between the ages of 6 and 12 years of age. The main outcome evaluated was the difference between groups on change in percent estimated body weight (%EBW) from baseline (BL) to end of treatment (EOT).
Method
Ninety-eight children with ARFID were randomized to 14 sessions over 4 months of telehealth FBT-ARFID or PMT. Assessments of weight/height, eating-related cognitions, and behaviors associated with ARFID were collected online at BL, 1 month, 2 months, and EOT by assessors masked to treatment condition.
Results
FBT-ARFID was superior to PMT at the EOT in promoting increased %EBW. There were no differences between groups on improvements in overall severity of ARFID symptoms or other related ARFID symptoms; however, BL severity of ARFID symptoms moderated the effect, with children who were most symptomatic improving significantly more in FBT-ARFID than in PMT (exploratory analyses).
Conclusion
FBT-ARFID is superior to PMT for promoting weight gain in low-weight children with ARFID, especially for those children with greater severity of ARFID symptoms.
