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).
