Area of Science:

  • Psychiatry
  • Clinical Psychology
  • Addiction Medicine

Background:

  • Limited research exists on sex differences in personality disorder profiles within Alcohol Use Disorder (AUD) populations.
  • Understanding these differences is crucial for tailored treatment strategies in AUD.
  • This study addresses the gap by examining sex-based variations in personality disorders among AUD patients.

Purpose of the Study:

  • To investigate sex differences in personality disorder profiles among individuals diagnosed with Alcohol Use Disorder (AUD).
  • To analyze both dimensional trait scores and categorical personality disorder types.
  • To identify specific personality disorders that show significant sex-based prevalence differences in an AUD sample.

Main Methods:

  • Utilized the Millon Clinical Multiaxial Inventory-III (MCMI-III) for assessment after a period of abstinence.
  • Analyzed data from 216 individuals (114 women, 102 men) seeking outpatient alcohol detoxification.
  • Employed both dimensional trait analysis and categorical cluster analysis of personality disorders.

Main Results:

  • No significant sex differences were observed in Cluster A personality traits (paranoid, schizoid, schizotypal).
  • Women reported higher histrionic traits (Cluster B), while men showed higher prevalence of narcissistic personality disorder.
  • Women exhibited elevated dependent and obsessive-compulsive traits (Cluster C), with dependent personality disorder being significantly more prevalent in women.

Conclusions:

  • Both dimensional and cluster approaches provide valuable insights into personality disorders in AUD.
  • Dependent personality disorder (Cluster C) robustly differentiates between sexes in AUD patients.
  • Personality disorder patterns in Clusters A and B demonstrate minimal sex differences when both analytical approaches are considered.
