Six-year course of bulimia nervosa.
OBJECTIVE
Because little is known about the longer-term course of bulimia nervosa, the 2- and 6-year course and outcome of 196 consecutively treated females with bulimia nervosa-purging type (BN-P) was assessed.


METHODS
One hundred ninety-six females with BN-P were assessed longitudinally at four points of time: at the beginning of therapy, at the end of therapy, at 2-year follow-up, and at 6-year follow-up. Self-rating scales as well as expert ratings from interview data were used. Eating disorder specific and general psychopathology was assessed.


RESULTS
The general pattern of results over time showed substantial improvement during therapy, a slight (in most cases nonsignificant) decline during the first 2 years after treatment, and further improvement and stabilization from 3 to 6 years posttreatment. At 6-year follow-up, 20.9% had BN-P, 0.5% BN-nonpurging type (BN-NP), 1.1% had shifted from BN to binge-eating disorder, 3.7% had anorexia nervosa, 1.6% were classified as eating disorder not otherwise specified (ED-NOS), and 2 patients had died; obesity with a body mass index (BMI) of > 30 was seen in 6.0%; the majority (71.1%) showed no major DSM-IV eating disorder.


CONCLUSIONS
Based on a composite global outcome score at 6 years follow-up, 59.9% achieved a good outcome, 29.4% an intermediate outcome, 9.6% a poor outcome, and 2 (1.1%) persons were deceased. Course and outcome were generally more favorable than in anorexia nervosa.
