Potential subjects aged 6 years to 12 years, 11 months old with DSM 5 ARFID, and weight equal to or between 75 to 88% EBW who are medically stable for outpatient treatment and their families will be recruited through Stanford University, pediatricians, mental health experts, clinics treating EDs, and local parents' groups. Those eligible for the program will be invited to read and sign informed consent forms and complete the baseline assessment. Participants will then be randomized to FBT-ARFID with medical management for 14 sessions provided over 4 months or manualized Non-Specific Care (NSC) with medical management for 4 months. NSC will consist of 14 sessions over 4 months.~There will be 5 major assessment time points: Baseline, 1 month, 2 months, End Of Treatment (4 months), and 6-month post-treatment Follow-Up. Both the child and the parent will complete measures at these time points. In addition, parents will complete short survey assessments after each of the 14 treatment sessions.
This study is examining the efficacy and mechanism of family therapy compared to usual care for children between the ages of 6 and 12 who are diagnosed with Avoidant/Restrictive Food Intake Disorder. Preliminary data suggest that family therapy is superior to usual care and that improvement in parental self-efficacy related to feeding their children is the mechanism of treatment. In addition, this study will attempt to identify specific patient groups who respond to family therapy.
