Study summary

Eating disorders are serious mental health disorders associated with high levels of mortality, disability, physical and psychological morbidity, and impaired quality of life. Family members who spend the majority of their time with patients of eating disorders experience heavy psychological burden. Remote family support programs consist of interpersonal psychotherapy and family psychoeducation. This study aimed to examine the effectiveness of a remote family support program for eating disorders in an RCT (randomized controlled trial). The specific objective was to conduct a small pilot RCT of the remote family support program (n=28) compared with TAU (n=28).
