摘要
目的从职业卫生的角度研制一套结构简单的职业生命质量(QWL)量表。方法通过文献查阅、头脑风暴、专家讨论等方法确定量表的维度和条目,形成预试问卷;将预试问卷应用到某教师群体进行预调查,并根据预调查结果对量表的维度和条目进行修订形成QWL量表;采用QWL量表对成都市的516名教师进行正式调查后计算量表的效度和信度,以调整量表的结构,形成QWL7-32量表。结果通过探索性因子分析提取出特征根>1的因子7个,累计贡献率为60.1%;验证性因子分析显示7因子模型的总体拟合效果比8因子模型理想;7因子模型的QWL7-32量表各维度与其相应的测量条目间有较高的相关系数,而与其他条目间相关系数较低;QWL7-32量表各个维度及总分的Cronbach’sα系数均大于或等于0.70(P<0.01),各维度及总分两次测量的相关系数均接近或大于0.60(P<0.01)。结论 QWL7-32量表具有较好的信度和效度,能够较全面、具体、准确地反映职业生命质量的内涵,可用于职业人群的职业生命质量测定与评价。
Objective To develop a simple structured scale measuring quality of working life （QWL） from the perspective of occupational health and safety. Methods We identified the dimensions and items of QWL through literature review, brainstorming and expert panel discussions, and developed a pre-test questionnaire. The pre-test questionnaire was tested in school teachers and revised accordingly. The QWL Scale was eventually validated in 516 school teachers in Chengdu. We examined the validity and reliability of the final scale （QWL7-32）. Results The exploratory factor analysis extracted seven factors with an eigenvalue greater than 1. Those seven factors contributed to 60.1% of the total variance. The confirmatory factor Analysis endorsed the seven factor model. The seven-dimension scale had good convergent validity and discriminant validity. The Cronbach＇s a coefficients of the QWL7-32 scale and all its seven dimensions were around or higher than 0.70 （P^0.01）. The test-retest correlation coefficients of the scale and all its seven dimensions were close to or greater than 0.60 （P^0.01）. Conclusion The QWL7-32 scale has acceptable validity and reliability. It measures QWL in a comprehensive, specific and accurate way, and can be used as an instrument for assessing QWL.
