高风险作业人员身体勇敢量表的修订

Revision of the Physical Courage at Work Scale

  • 摘要: 背景 据《中国劳动统计年鉴2020》的统计数据,2019年我国有113 293人因公受伤,25092因工死亡。提升高风险作业人员的勇敢素质,对个人健康维护和组织工作效能强健具有重要意义。

    目的 在中国人群中修订高风险作业人员身体勇敢量表(PCWS)。

    方法 对1280名高风险作业人员进行施测,采用项目分析和探索性因子分析法对量表的建构效度进行分析,采用验证性因子分析法验证探索性因子分析的结果,采用Cronbach's α系数验证量表的信度,采用Pearson相关分析做PCWS与军人心理素质量表勇敢分量表(MQQA)、Norton勇敢量表(CM)的相关性来验证量表的聚合效度,采用Pearson相关分析做PCWS各因子的相关性来验证量表的区分度。

    结果 项目分析结果显示,所有题项与总分相关系数均大于0.4;探索性因子分析结果显示,高风险作业人员身体勇敢量表修订版在中国人群中包括:直接危险、供养家庭、应对他人攻击、报告违纪、帮助社会5个维度;共解释方差总变异的72.71%。验证性因子分析结果表明高风险作业人员身体勇敢量表修订版五因子修正模型拟合良好卡方自由度比(CMIN/DF)=4.60,规准适配指数(NFI)=0.93,比较适配指数(CFI)=0.95,增值适配指数(IFI)=0.95,标准化残差均方和平方根(SRMR)=0.05,渐进残差均方和平方根(RMSEA)=0.07。信度分析结果表明该量表在调查人群中的内部一致性系数为0.95,效度分析结果表明该量表与MQQA、CM的相关系数在0.11~0.28间(P<0.01),区分度结果表明该量表各因子间相关系数在0.35~0.72间(P<0.01)。

    结论 高风险作业人员身体勇敢量表修订版在中国人群中具有良好的信效度。

     

    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.
