Abstract
Aim. To study in a prospective manner the long-term prognostic value of the initially recorded Eating Disorder Inventory (EDI) scores in anorexia nervosa (AN) patients. Methods. The 5–10-year outcome of 26 consecutive malnourished AN patients was prospectively recorded according to the initial EDI score. We selected only patients with full 6-month assessments for more than 5 years (mean 8.5 years). Eating behavior, quality of life, autonomy and insight capacity were prospectively assessed by the Morgan-Russell scale and a semi-structured interview. At the end of follow-up, 13 patients recovered and the 13 others had a poor outcome. Results. In monovariate analyses, high initial EDI total score ( P < .0007) and high initial scores for perfectionism (P < .001), ineffectiveness (P < .002), interpersonal distrust ( P < .004), interoceptive awareness ( P < .03) and drive for thinness ( P < .05) were significantly associated with a poor prognosis 5–10 years afterward. In a multivariate analysis, only high initial scores for perfectionism (F = 8.43; P = 0.008) and interpersonal distrust (F = 7.46; P = 0.012) were significantly associated with illness severity. Discussion. High EDI total score and subscales for perfectionism and interpersonal distrust could predict a long-term severe outcome in AN.
