Cognitive behavioral therapy may reduce relapse risk for adults with AN after weight restoration , although its efficacy in the underweight state remains unknown .
Variants of family therapy are efficacious in adolescents , but not in adults .
Evidence for AN treatment is weak ; evidence for treatment-related harms and factors associated with efficacy of treatment are weak ; and evidence for differential outcome by sociodemographic factors is nonexistent .

Three psychotherapies for anorexia nervosa: a randomized, controlled trial.
OBJECTIVE Few r and omized , controlled trials have examined the efficacy of treatments for anorexia nervosa .  Cognitive behavior therapy and interpersonal psychotherapy are effective in a related disorder , bulimia nervosa . There are theoretical and treatment indications for these therapies in anorexia nervosa . METHOD Fifty-six women with anorexia nervosa diagnosed by using strict and lenient weight criteria were r and omly assigned to three treatments . Two were specialized psychotherapies ( cognitive behavior therapy and interpersonal psychotherapy ) , and one was a control treatment combining clinical management and supportive psychotherapy ( nonspecific supportive clinical management ) . Therapy consisted of 20 sessions over a minimum of 20 weeks . RESULTS For the total study group ( intent-to-treat group ) , there were significant differences among therapies in the primary global outcome measure . Nonspecific supportive clinical management was superior to interpersonal psychotherapy , while cognitive behavior therapy was intermediate , neither worse than nonspecific supportive clinical management nor better than interpersonal psychotherapy . For the women completing therapy , nonspecific supportive clinical management was superior to the two specialized therapies . CONCLUSIONS The finding that nonspecific supportive clinical management was superior to more specialized psychotherapies was opposite to the primary hypothesis and challenges assumptions about the effective ingredients of successful treatments for anorexia nervosa
