Weight gains were more rapid in adolescents and inpatient treatment .
Background : The aim of the study was a systematic review of studies evaluating psychotherapeutic treatment approaches in anorexia nervosa and to compare their efficacy .
Weight gain was chosen as the primary outcome criterion .

Enhanced cognitive behaviour therapy for adults with anorexia nervosa: A UK–Italy study
Anorexia nervosa is difficult to treat and no treatment is supported by robust evidence . As it is uncommon , it has been recommended that new treatments should undergo extensive preliminary testing before being evaluated in r and omized controlled trials . The aim of the present study was to establish the immediate and longer-term outcome following “ enhanced ” cognitive behaviour therapy ( CBT-E ) .  Ninety-nine adult patients with marked anorexia nervosa ( body mass index ≤ 17.5 ) were recruited from consecutive referrals to clinics in the UK and Italy . Each was offered 40 sessions of CBT-E over 40 weeks with no concurrent treatment . Sixty-four percent of the patients were able to complete this outpatient treatment and in these patients there was a substantial increase in weight ( 7.47 kg , SD 4.93 ) and BMI ( 2.77 , SD 1.81 ) . Eating disorder features also improved markedly . Over the 60-week follow-up period there was little deterioration despite minimal additional treatment . These findings provide strong preliminary support for this use of CBT-E and justify its further evaluation in r and omized controlled trials . As CBT-E has already been established as a treatment for bulimia nervosa and eating disorder not otherwise specified , the findings also confirm that CBT-E is transdiagnostic in its scope
