Psychosocial functioning on the Independent Living Skills Survey in older outpatients with schizophrenia

Improving real-life community functioning in patients with severe mental illness has been an important recent focus of treatment outcome research. Few studies, however, have examined psychosocial functioning in older psychotic patients. The Independent Living Skills Survey (ILSS) is a measure of the basic functional living skills of individuals with severe and persistent mental illness. The self-report version of the ILSS was administered to 57 middle-aged and older community dwelling outpatients with schizophrenia and 40 age-comparable nonpsychiatric participants. Regardless of whether patients resided in assisted living or independent settings, they showed significantly impaired functioning on a majority of the functional areas assessed by the ILSS. No consistent relationship was found between symptom severity and functioning. With certain modifications, the ILSS appears to be a sensitive indicator of functional impairment in this older sample of community-dwelling outpatients with schizophrenia. Information provided by the instrument might be useful to guide rehabilitation efforts and measure functioning changes in response to treatment in this population.
