A comparison of short- and long-term family therapy for adolescent anorexia nervosa.
OBJECTIVE Research suggests that family treatment for adolescents with anorexia nervosa may be effective . This study was design ed to determine the optimal length of such family therapy . METHOD Eighty-six adolescents ( 12 - 18 years of age ) diagnosed with anorexia nervosa were allocated at r and om to either a short-term ( 10 sessions over 6 months ) or long-term treatment ( 20 sessions over 12 months ) and evaluated at the end of 1 year using the Eating Disorder Examination ( EDE ) between 1999 and 2002 . RESULTS Although adequately powered to detect differences between treatment groups , an intent-to-treat analysis found no significant differences between the short-term and long-term treatment groups . Although a nonsignificant finding does not prove the null hypothesis , in no instance does the confidence interval on the effect size on the difference between the groups approach a moderate .5 level . However , post hoc analyses suggest that subjects with severe eating-related obsessive-compulsive features or who come from nonintact families respond better to long-term treatment . CONCLUSIONS A short-term course of family therapy appears to be as effective as a long-term course for adolescents with short- duration anorexia nervosa . However , there is a suggestion that those with more severe eating-related obsessive-compulsive thinking and nonintact families benefit from longer treatment
