ranged from 0.70 for Depressive Personality Disorder, to 0.90 for Obsessive-compulsive Personality Disorder, with a mean
of 0.81 for all the personality disorders. The mean trait intraclass correlation coefficient score was 0.90 and the summed
score was 0.83. The overall interrater reliability was shown to be good across all the studies.
