RESUMO
Schizophrenia is a disabling mental disorder that is associated with impairments in both social and occupational functioning. Few studies, however, have explored functional domains of disability and its associations with age, sex, and length of care. As part of a hospital quality improvement initiative, data were collected on outpatients' age, sex, length of care, and levels of disability (using the WHODAS 2.0; N=180; M=45.72; 68% male). Mean disability summary and domain scores were compared with population norms from international samples and two published studies in schizophrenia. A series of three-way ANOVAs and post-hoc tests evaluated differences in levels of disability based on age, sex, and length of care categories. Sample mean summary scores were comparable to published studies in schizophrenia (M=24.81; SD=17.37; 85th percentile). Statistically significant main effects of sex and age on summary and domain-specific scores were found, whereas length of care was not significant. A statistically significant three-way interaction of sex x length of care x age was found for summary and mobility scores. Findings provide support for the reliability and validity of the WHODAS 2.0 in outpatients with schizophrenia. Although causal inferences cannot be made, findings show that age and sex are important factors to consider in addressing disability.
