The purpose of this study was to characterize the inter-rater reliability of two physical exposure assessment methods of the upper extremity, the Strain Index (SI) and Occupational Repetitive Actions (OCRA) Checklist. These methods are commonly used in occupational health studies and by occupational health practitioners.

Inter-rater reliability was characterized using a single-measure, agreement-based intraclass correlation coefficient (ICC). Inter- rater reliability of SI assessments was moderate to good (ICC 1⁄4 0.59, 95% CI: 0.45e0.73), a similar finding to prior studies.

Abstract

The purpose of this study was to characterize the inter-rater reliability of two physical exposure assessment methods of the upper extremity, the Strain Index (SI) and Occupational Repetitive Actions (OCRA) Checklist. These methods are commonly used in occupational health studies and by occupational health practitioners. Seven raters used the SI and OCRA Checklist to assess task-level physical exposures to the upper extremity of workers performing 21 cheese manufacturing tasks. Inter-rater reliability was characterized using a single-measure, agreement-based intraclass correlation coefficient (ICC). Inter- rater reliability of SI assessments was moderate to good (ICC 1⁄4 0.59, 95% CI: 0.45e0.73), a similar finding to prior studies. Inter-rater reliability of OCRA Checklist assessments was excellent (ICC 1⁄4 0.80, 95% CI: 0.70e0.89). Task complexity had a small, but non-significant, effect on inter-rater reliability SI and OCRA Checklist scores. Both the SI and OCRA Checklist assessments possess adequate inter-rater reliability for the purposes of occupational health research and practice. The OCRA Checklist inter- rater reliability scores were among the highest reported in the literature for semi-quantitative phys- ical exposure assessment tools of the upper extremity. The OCRA Checklist however, required more training time and time to conduct the risk assessments compared to the SI.
