综合性工作能力指数量表的编制

Development and evaluation of Comprehensive Work Ability Index scales

目的建立综合评价工作能力的测量工具——综合性工作能力指数（comprehensive Work Ability Index，CWAI）量表。方法采用整群随机抽样方法抽取某厂198名在职职工作为研究对象，以工作能力理论模式为基础，根据量表编制的标准方法，采用项目区分度分析、相关系数法和因子分析方法筛选CWAI量表条目。结果CWAI量表属于自评式工作能力评价量表，共包括5个项目，涉及工作能力总体评价、生理状态（如现患疾病及其影响）、心理状态（如工作满意度、精神状态等）、社会功能状态（如社会支持、社会适应等）、工作能力预测等方面的信息，所有项目的累计得分即为CWAI。CWAI是评价工作能力的依据。结论CWAI量表结构较清晰、稳定，与预期理论结构相吻合，但在实际应用前尚需进行量表的信度与效度评价。

Objective To compile the instrument of comprehensive work ability evaluation-Comprehensive Work Ability Index （CWAI） scales. Methods One hundred and ninety-eight employees were selected with the random cluster sampling method from a factory. On the basis of the work ability theory,CWAI scales,a self-rating scales on work ability,was developed according to the standardized processes of scales compilation. Item differentiation analysis, principal component analysis and factor analysis as well as intra-item reliability were used for selecting the item of CWAI scales. Results Work ability was assessed with a comprehensive work ability index, which was a comprehensive indicator constructed on the basis of the responses to the scales. It was derived as the sum of the five items including self-rating work ability domain, physiological domain （disease, sick leave etc. ）, psychological domain （work satisfaction, mental state etc. ）, social functions dominant （social support, social flexibility etc.） and work ability prediction domain. Conclusion CWAI scales correspond with the theoretical structure. However,the reliability and validity of CWAI scales must be assessed before the formal application.
