OBJECTIVES: To evaluate the agreement between job-title based estimates for upper extremity physical work exposures and exposure estimates from work observation and worker self-report. METHODS: Self-reported exposure questionnaires were completed by 972 workers, and exposure estimates based on worksite observation were completed for a subset of 396 workers. Job-title based estimates were obtained from O*NET, an American database of job demands. Agreement between self-reported, observed and job-title based physical work exposures was assessed using Spearman correlations and intraclass correlation coefficients. RESULTS: Job-title based exposure estimates from O*NET, self-reported and observer-rated exposures showed moderate to good levels of agreement for some upper extremity exposures, including lifting, forceful grip, use of vibrating tools and wrist bending. CONCLUSIONS: Job-title based physical work exposure variables may provide useful surrogate measures of upper extremity exposure data in the absence of other individual level data such as observed or self-reported exposure. Further validation of these data is necessary to determine the utility of the O*NET databases in future epidemiological studies.
