BACKGROUND: Work-related musculoskeletal disorders (WMSDs) are a major public health concern. There has been a strong demand from occupational safety and health agencies and operators to develop simple tools for risk assessment and management of WMSDs. The Quick Exposure Check (QEC) was designed to assess exposure to WMSDs risk factors affecting the back, shoulder/upper arm, wrist/hand, and the neck. It is a valuable observational ergonomic assessment tool, suitable for field-based assessment.OBJECTIVE: This study set out to translate, culturally adapt, and validate a Chinese version of the Quick Exposure Check (CQEC), an observational tool used to assess exposure to physical and psychosocial workplace risk factors for the development of WMSDs in different body sites.METHODS: The CQEC was translated from its original English version using a forward- and back-translation approach. Content validity was examined by an expert panel and expert committee using item- and scale-level content validity indices. The intra-class correlation coefficient (ICC) was used to analyze the inter-rater reliability of the observer's assessment, with kappa statistics and percentage agreements used to estimate the test-retest reliability of the worker's assessment of individual items.RESULTS: The CQEC demonstrated an excellent scale-level content validity index (S-CVI > 0.90). The ICC lay between 0.71 and 0.97, indicating good inter-rater reliability. Test-retest reliability showed substantial agreement between the two measurement occasions for most of the items (kappa=0.68 to 1, percentage agreement=76 to 100%) capturing exposure to risk factors.CONCLUSIONS: The CQEC is a valid and reliable tool that can be used to calculate levels of exposure to risk factors for WMSDs.
