Relapse from remission at two- to four-year follow-up in two treatments for adolescent anorexia nervosa.
OBJECTIVE Long-term follow-up studies documenting maintenance of treatment effects are few in adolescent anorexia nervosa ( AN ) . This exploratory study reports relapse from full remission and attainment of remission during a 4-year open follow-up period using a convenience sample of a subgroup of 65 % ( n = 79 ) from an original cohort of 121 participants who completed a r and omized clinical trial comparing family-based therapy ( FBT ) and adolescent-focused individual therapy ( AFT ) .  METHOD Follow-up assessment s were completed up to 4 years posttreatment ( average , 3.26 years ) . Available participants completed the Eating Disorder Examination as well as self-report measures of self-esteem and depression at 2 to 4 years posttreatment . RESULTS Two participants ( 6.1 % ) relapsed ( FBT : n = 1 , 4.5 % ; AFT : n = 1 , 9.1 % ) , on average 1.98 years ( SD = 0.14 years ) after remission was achieved at 1-year follow-up . Ten new participants ( 22.7 % ) achieved remission ( FBT : n = 1 , 5.9 % ; AFT : n = 9 , 33.3 % ) . Mean time to remission for this group was 2.01 years ( SD = 0.82 years ) from 1-year follow-up . There were no differences based on treatment group assignment in either relapse from full remission or new remission during long-term follow-up . Other psychopathology was stable over time . CONCLUSION There were few changes in the clinical presentation of participants who were assessed at long-term follow-up . These data suggest that outcomes are generally stable posttreatment regardless of treatment type once remission is achieved .
