Abstract: Background According to China's Labor Statistics Yearbook 2020, there were 113293 work-related injuries and 25092 work-related deaths in 2019. It is of great significance to enhance the courage quality of high-risk workers for the maintenance of personal health and the effectiveness of organizational work. Objective To revise the Physical Courage at Work Scale (PCWS) for its application in Chinese employees exposed to high-risk workplace. Methods A total of 1280 high-risk workers completed the revised PCWS for Chinese employees. Item analysis and exploratory factor analysis were used to analyze the scale's construction validity. Confirmatory factor analysis was used to verify the results of exploratory factor analysis, Cronbach's α coefficient was used to verify the reliability of the scale, Pearson correlation analysis of the scale with Mental Quality Questionnaire for Armymen (MQQA) and Norton Courage Measure (CM) was used to verify the validity of the revised PCWS, and Pearson correlation analysis was used to determine the discrimination for each factor of the revised PCWS. Results The results of item analysis showed that the correlation coefficients between the scores of all items and the total score of the revised PCWS were greater than 0.4. The exploratory analysis indicated that there were five factors including immediate danger,providing for family, confronting other's aggression, reporting violations, and contributing to society in the revised version. The confirmatory analysis indicated the five-factor model fitted well (minimum fit function Chi-square/degree of freedom, CMIN/DF=4.60; normed fit index, NFI=0.93; comparative fit index, CFI=0.95; incremental fit index, IFI=0.93; standardized root mean square residual, SRMR=0.05; root mean square error of approximation, RMSEA=0.07). The internal consistency coefficient of the revised PCWS was α=0.95. The correlation coefficients of the revised PCWS with MQQA and CM ranged from 0.11 to 0.28 (P<0.01), and the correlation coefficients between factors of the revised scale ranged from 0.35 to 0.72 (P<0.01). Conclusion The revised PCWS has good reliability and validity in Chinese employees.
