Recent research has established a pattern of impairment and distress associated with the symptoms of DSM-IV Axis II disorders such that personality disorders occurring more commonly among males are associated with more social and occupational impairment, but less personal distress, than personality disorders occurring more commonly among females. The current study examined whether a similar pattern exists for DSM-IV Axis-I disorders. Lay judges (N = 206) rated the social impairment, occupational impairment, and personal distress associated with the symptoms of six male typed and six female-typed Axis-I disorders. Impairment and distress were associated with male-typed and female-typed Axis-I disorders in the same manner as personality disorders. Reasons for the emphasis of social and occupational impairment among male-typed disorders and distress among female-typed disorders are discussed.

The issue of comorbidity within the Axis II personality disorders was explored using a large sample of university students who were administered the Coolidge Axis II Inventory (CATI). Comorbidity patterns with this normal sample were compared with recent clinical data reported by several other researchers. The results confirm the high degree of comorbidity within Axis II and the similarity in the comorbidity patterns with clinical and nonclinical samples. With the CATI, a 30.4% comorbidity rate was obtained for Histrionic and Narcissistic Personality disorders (Pd). The paranoid, passive-aggressive and borderline personality disorder traits were comorbid with several other Pds. For Cluster A, there was low comorbidity except for Paranoid Pd and Schizotypal Pd. With Cluster B, the co-occurrence was moderate to strong. A moderate amount of interrelationship was obtained for the Cluster C Pds. The DSM-IV clusters were also strongly interrelated. An additional finding was the similarity between self-report and structured interview methodology in obtained personality disorder comorbidity.

The Defense Style Questionnaire-40 is a 40 item short form of the 88 item Defense Style Questionnaire. A cross-cultural comparison was made between a sample of 635 Canadian university students and an Australian sample of 388 subjects reported by Andrews, Singh, and Bond. Differences between the two samples were noted for several of the defense scales. These may be a reflection of differential socialization patterns in coping with stress for the two countries. Gender and age comparisons were made for the 20 defense scales. Some interesting differences were noted for gender on the suppression, pseudoaltruism, and isolation scales. The internal structure of defense styles was also found to have similarities and differences for males and females with the DSQ-40.

The Coolidge Axis-II Inventory (CATI) is a 200-item self-report inventory that is designed to measure DSM-IV personality disorders (PD's). Norms with a sample of 1,790 Canadian college students are compared with a US sample of 573 college students and 36 elderly subjects. Comparisons for the 11 DSM-IV personality disorder scales are made with several age groups and with gender. Some interesting similarities and differences were observed. With the Canadian sample, a gender difference was found on the antisocial scale. Age differences were found for on several PD scales in that younger respondents (17-24 years) scored higher than the older ones (25-57 years). This information is likely to be helpful to clinicians in monitoring age related behavioral changes in personality disorder.
