General and Symptom-Specific Illness Duration and Course as Predictors of Symptom Severity in Anorexia Nervosa.

ABSTRACT:

Objective

Illness duration has been examined as a predictor of anorexia nervosa (AN) outcomes to mixed results, yet is frequently used to make treatment and prognosis decisions. More specific metrics, such as prior illness course (e.g., continuous vs. intermittent symptoms) and symptom-specific duration or course, may more effectively predict concurrent and longitudinal outcomes.

Method

Adults with acute or weight-restored AN (N = 75) completed a measure assessing duration and course (e.g., continuous, intermittent) of their eating disorder in general and of specific symptoms (low weight, restrictive eating, weight/shape preoccupation). Hierarchical linear regressions predicted the severity of each symptom (BMI, restrictive eating, shape concern, weight concern) at baseline
