Longitudinal follow-up of a comprehensive operationalization of eating disorder recovery: Concurrent and predictive validity
International Journal of Eating Disorders Jul 17, 2019
Bardone-Cone AM, et al. - In a sample followed up 7–8 years from baseline, the concurrent validity of a comprehensive definition of eating disorder recovery (physical, behavioral, and cognitive indices) was replicated. In addition, predictive validity was examined, for the first time with this comprehensive definition. Sixty-six women with a history of an eating disorder and 31 age-matched controls completed an online survey and phone interview for this work. In general, women who were fully recovered and controls were statistically indistinguishable. Fully recovered women showed significantly less eating disorder attitudes and behaviors than the partially recovered and eating disorder groups. Robust predictor of stability was being fully recovered at baseline: of those fully recovered at baseline, 80% remained fully recovered at follow-up. At follow-up, attainment of full recovery was observed for one-third of those with an eating disorder and one-half of those in partial recovery at baseline. Findings thereby support the validity of the current operationalization of eating disorder recovery, encompassing physical, behavioral, and cognitive indices and emphasize the possibility of full recovery as well as its predictive ability for full recovery years later.
