Family Therapy Is First-Line for Adolescent Anorexia — But Not for the Reasons You Think

Family therapy works best for adolescent anorexia. Every clinician knows this. But this International Journal of Eating Disorders review specifies exactly what "works" means — and what it does not. FBT excels at physical recovery: weight gain, medical stability, staying out of hospital. It does not consistently outperform individual therapy on the psychological core of the disorder.

What FBT actually does better

The review analysed 22 RCTs across outpatient, inpatient, and day-patient settings — the first to focus exclusively on adolescent samples rather than mixing in adult data. The pattern is clear: FBT produces better physical outcomes. Weight restoration, reduced rehospitalisation, medical stability — the measurable, life-saving indicators.

But eating-disorder cognitions — body image distortion, fear of weight gain, restrictive thinking patterns — did not consistently improve more with FBT than with individual approaches like CBT-E or adolescent-focused therapy. The psychological engine of the disorder responds to direct psychological intervention, regardless of whether the family is in the room.

The clinical implication

This is not an argument against FBT. It is an argument for precision. FBT should remain first-line because physical recovery is the immediate priority in adolescent AN — patients die from the physical consequences, not from the cognitions. But clinicians should not assume that successful weight restoration means the eating disorder is treated. The cognitive work may require a different modality, either concurrently or sequentially.

The review also found that shorter inpatient stays combined with outpatient follow-up produced outcomes comparable to extended hospitalisation — supporting the trend toward deinstitutionalisation in adolescent eating disorder care.
