The researchers interviewed 2,053 individuals aged 18-65 years, drawn at random from the National Register of Oslo. Information about each individual's personality disorders was obtained by means of the Structured Interview for DSMI1I-R Personality Disorders (Arch. Gen. Psychiatry 58:590-96, 2001).
The prevalence of any personality disorder in the sample was approximately 13%, with women experiencing a greater incidence than men (14.6% versus 13.7%). The most prevalent personality disorder was avoidant personality disorder (5%), the researchers reported.
Paranoid, histrionic, and obsessivecompulsive disorders also were common, while the rarest disorders were sadistic, schizotypal, antisocial, and borderline, Dr. Torgersen and his associates noted.
Antisocial, passive-aggressive, and obsessive-compulsive disorders were significantly more common among the men studied. Borderline, histrionic, dependent, and self-defeating disorders were more common among women. However, the differences were not significant.
This study presented some new and noteworthy data. Although the observed prevalence or personality disorders in the present study was almost identical to that of pooled data from earlier studies, the prevalence of avoidant, paranoid, and schizoid personality disorders was considerably higher than previously reported, and the rate of borderline personality disorder was lower, the researchers noted. …
