This study examined the extent and nature of bias associated with self-reported versus standardized physician-examination/assessment-based accounts of musculoskeletal disease in a sample of 406 persons chosen to represent an aging and dependency continuum. Prevalence of musculoskeletal disease based on standardized physician examination/assessments was 97%. Using the standardized findings as the criterion, the self-report underestimated prevalence by 16%. Overall, the results indicated that self-reports of musculoskeletal conditions by the elderly capture the vast majority of persons with painful or functionally significant disease and are most valid for persons from ages 65 to 74 but do not reflect the presence of asymptomatic joint pathology. Standardized physician examinations/assessments would more accurately determine the presence of risk factors in epidemiological studies of musculoskeletal disability.
