Section snippets
Participants and Procedure
In the original study, subjects and families were randomly assigned for treatment with manual-based family therapy for 6 or 12 months (Lock et al., 2005). Efficacy was compared at the end of 1 year by examining primary outcomes of body mass index (BMI) and global Eating Disorder Examination (EDE) score. Eighty-six subjects were involved in this study, ranging in age from 12 to 18 years. All of the subjects were diagnosed with AN by DSM-IV criteria with the exception that for those subjects who
RESULTS
In this follow-up study, 86% (74/86) of the subjects were contacted. Three refused to participate. This resulted in a sample size of 71 (83%) subjects, of whom 35 (49%) completed EDEs. Information was largely obtained through the subjects themselves and through parents (Table 1). Mean length of follow-up was 3.96 years (range 2.3-6.0), and the mean age of subjects was 19.2 years (range 15.5-23.2) at the time of follow-up.
DISCUSSION
Our hypothesis that there would be no differences between the short and long versions of family treatment at long-term follow-up was supported by the findings of this study. No statistical differences were detected between the two groups at a mean of almost 4 years after the end of treatment. Furthermore, there was no evidence of increased treatment utilization by the shorter-term treatment group in terms of psychotherapy, medication, or hospitalization. Thus, it is reasonable to conclude that
