Gender differences in psychiatric diagnoses among inpatients with and without intellectual disabilities.

There are few published studies on the relationship between gender and psychiatric disorders in individuals with intellectual disabilities. Adults (N = 1,971) with and without intellectual disabilities who received inpatient services for psychiatric diagnosis and clinical issues were examined. Among individuals with intellectual disabilities, women were more likely to have a diagnosis of mood disorder and sexual abuse history; men were more likely to have a substance abuse diagnosis, legal issues, and past destructive behavior.

The clinical profile and service needs of hospitalized adults with mental retardation and a psychiatric diagnosis.

Objective: This study compared patients with both mental retardation and a psychiatric diagnosis with patients who did not have co-occurring mental retardation who were served in Ontario's tertiary mental health care system in terms of demographic characteristics, symptom profile, strengths and resources, and clinical service needs.

Methods: A secondary analysis of data from the Colorado Client Assessment Record (CCAR) that were collected between 1999 and 2003 from all tertiary psychiatric hospitals in Ontario, Canada, was completed for a random sample of 3,927 cases, representing 12,470 patients receiving psychiatric services.

Results: Patients with both mental retardation and a psychiatric diagnosis differed from those who did not have mental retardation in terms of demographic characteristics, diagnostic and symptom profile, resources, and recommended level of care.
