Reliability and validity of Chinese version Occupational Repetitive Actions Checklist in shipbuilding industry

  • Objective To evaluate the reliability and validity of Chinese version Occupational Repetitive Actions (OCRA) Checklist used in shipbuilding industry.

    Methods The risk of work-related musculoskeletal disorders (WMSDs) in 241 workers at a shipyard in North China was evaluated by the OCRA Checklist. Intra-rater reliability, inter-rater reliability, and Cronbach'α coefficient were used to assess the reliability of the checklist; and discriminant validity was used to assess the validity.

    Results Regarding the OCRA Checklist applied, the intraclass correlation coefficients (ICC) of intra-rater reliability and interrater reliability were 0.60 and 0.44 respectively. Each factor's intra-rater reliability and inter-rater reliability ranged from 0.35 to 0.86 and from 0.41 to 0.76 respectively. The Cronbach'α coefficient was 0.63. The correlation coefficients between each factor (including recovery, frequency, force, posture, and additional factor) and total items were 0.19, 0.44, 0.75, 0.87, and 0.84, respectively.

    Conclusion The Chinese version OCRA Checklist basically accommodates the requirements to assess shipbuilding workers' WMSDs, but still needs further adjustment.
