Older patients with schizophrenia: nature of dwelling status and symptom severity.

Objective: This cross-sectional study enrolled elderly patients with diagnoses of schizophrenia or schizoaffective disorder.

Method: The 85 subjects were dichotomized into two groups on the basis of dwelling status: those living independently (N=35) and those living in residential settings (N=50). The groups were compared with regard to scores on the Mini-Mental State Examination (MMSE), the Brief Psychiatric Rating Scale, the Scale for the Assessment of Negative Symptoms (SANS), the Geriatric Depression Scale and by age.
