Prevalence of personality disorders in two geropsychiatric inpatient units.
One hundred males from a Veterans Affairs geropsychiatric inpatient ward, and 100 females from a geropsychiatric inpatient ward of a private hospital completed the Structured Interview for Disorders of Personality-Revised (SIDP-R). Chart reviews provided information including age, years of education, marital status, race, as well as Axis I and Axis II psychiatric diagnoses. Data from a young adult sample, drawn from an initial SIDP-R validation study, were used for comparison. Results indicate a 56.5% rate of personality disorders (PD) for older patients. Significantly more elderly men than elderly women were diagnosed with PD by psychiatric evaluation, and elderly men were also more likely to be diagnosed with paranoid, avoidant, and multiple PD using the SIDP-R. Psychiatrists gave far fewer Axis II diagnoses than were yielded by the SIDP-R, particularly with females. There were no significant differences in total PD rates between aged and young subjects, but older adults with PD were diagnosed less frequently with multiple PD. Older adults were also less likely to be diagnosed with the "Dramatic" cluster PD, and more likely to be diagnosed with the "Odd" cluster PD. The level of depression was related to both clinical and SIDP-R diagnoses.
