Area of Science:

  • Psychiatry
  • Psychology
  • Clinical Neuroscience

Background:

  • Anorexia nervosa (AN) is a complex eating disorder with significant personality correlates.
  • Existing research presents methodological challenges in accurately assessing personality in AN populations.

Purpose of the Study:

  • To review the empirical literature on the relationship between anorexia nervosa and personality.
  • To identify common personality phenotypes and variations within the AN diagnostic category.
  • To explore the predictive role of personality variables on the course and outcome of AN.

Main Methods:

  • A selective review of existing empirical studies was conducted.
  • Literature examining the relationship between AN and personality traits was synthesized.

Main Results:

  • A common phenotype in restricting-type AN includes high levels of obsessionality, restraint, and perfectionism.
  • Significant variability in personality variables exists within the AN diagnostic category.
  • Personality variables demonstrate potential to predict the course and outcome of AN.

Conclusions:

  • Personality traits are intricately linked to anorexia nervosa, potentially acting as risk factors, consequences, or shared etiological elements.
  • Further research is needed to develop empirically testable conceptual models clarifying these complex relationships.
  • Understanding personality's role is crucial for predicting and managing AN trajectories.
