Empirical definitions of remission and recovery from eating disorders are needed to understand outcome data and compare results across studies.
106 treatment-seeking women with hulimia nervosa, who had abstained from hinging and purging for at least 4 weeks, were followed prospectively.
Relapse was defined as at least 4 consecutive weeks of either binging and purging weekly or hinging two or more times per week, regardless of purging.
Recovery was differentiated from remission based on the probability of relapse.
The minimum number of weeks after which the risk of relapse leveled off was used as the cut-off to distinguish between the two outcomes.
Kaplan-Meier methods were used to estimate the weekly probability of relapse.
When defining remission as at least 4 weeks of being asymptomatic, a quarter of the women relapsed within 1 1 weeks.
By 37 weeks, only 49% of the women remained asymptomatic (95% Cl, 41-61).
The probability of relapse was substantial for approximately a year after a woman ceased to hinge and purge.
Bulimia nervosa is an episodic disorder.
As a conservative approach, periods of being asymptomatic that last less than 1 year should he laheled as remissions, not recoveries.
