title: A pilot study of personality pathology in patients with anorexia nervosa: modifiable factors related to outcome after hospitalization.
abstract: OBJECTIVE
  To assess improvement in aspects of personality in patients hospitalized with anorexia nervosa (AN) and its relationship to improved depression, body mass index (BMI), and eating disorder outcome after treatment.
  
  
  METHODS
  Twenty females hospitalized with AN completed intake and discharge assessments of BMI, depression and eating disorder severity, as well as personality pathology with the Minnesota Multiphasic Personality Inventory (MMPI-2) and the Revised NEO Personality Inventory (NEO PI-R). Clinical outcome for a subset of patients at 1-year post-hospitalization was determined.
  
  
  RESULTS
  The only factor that predicted better versus worse outcome at 1-year post-hospitalization was change in Low Self-Esteem (LSE) from the MMPI-2. Improved LSE from admission to discharge predicted remission at 1-year post-hospitalization, while worsening LSE predicted relapse. Regardless of outcome, NEO PI-R Neuroticism remained pathologically elevated in AN patients during hospitalization.
  
  
  CONCLUSIONS
  Pathological levels of neuroticism may represent a vulnerability factor for AN. In contrast, self-esteem appears to be a modifiable factor that predicts outcome following hospitalization, and may be an important target for treatment.
