Associations among eating disorder behaviors and eating disorder quality of life in adult women with anorexia nervosa.

The study examined associations between eating disorder behaviors measured via ecological momentary assessment (EMA) and eating disorder quality of life (EDQOL) in anorexia nervosa (AN). Women with AN (N = 82) completed an EDQOL measure and two-weeks of EMA. Greater frequency of EMA-assessed restriction and bulimic behavior were independently related to lower EDQOL scores. Lower psychological EDQOL was associated with increased EMA dietary restriction; lower work-related EDQOL was associated with increased EMA binge eating; aspects of EDQOL were unrelated to EMA purging. Findings suggest that severity of restriction and bulimic behaviors may serve as severity indicators of EDQOL in AN.
