Area of Science:

  • Psychiatry
  • Psychology

Background:

  • Eating disorders (EDs) are complex mental health conditions.
  • Personality traits are increasingly recognized as potential risk factors for EDs.

Purpose of the Study:

  • To investigate the association between specific personality prototype groups and the risk of developing eating disorders.
  • To identify distinct personality profiles linked to increased ED risk.

Main Methods:

  • Utilized the Revised NEO Personality Inventory (NEO-PI-R) and Eating Disorder Inventory 2 (EDI-2).
  • Employed cluster analysis to categorize participants into personality groups (high-functioning, undercontrolled, overcontrolled).
  • Applied logistic regression to assess the risk of EDs across personality groups.

Main Results:

  • The undercontrolled personality group exhibited a 6.5-fold higher risk of EDs compared to the high-functioning group.
  • The overcontrolled personality group demonstrated a nearly 16-fold higher risk of EDs compared to the high-functioning group.

Conclusions:

  • Identified undercontrolled and overcontrolled personality subtypes as significantly associated with elevated ED risk.
  • Results suggest that targeted prevention and treatment strategies for EDs should consider these specific personality profiles.
