摘要
目的 研究职业生活质量量表（Professional Quality of Life Scale,ProQOL）在汶川地震灾区政府工作人员中应用的信度和效度.方法 方便抽样1 175例汶川地震灾区政府工作人员自评完成ProQOL量表和心理健康自评问卷（Self-reporting Questionnaire,SRQ）.采用相关分析、t检验和验证性因子分析评价量表的信度和效度.结果 3个分量表与各自内部条目之间的相关系数分别为0.590～0.752、0.389～0.603和0.340～0.647（平均相关系数分别为0.672、0.482和0.555）,均具有统计学意义（P＜0.05）.30个条目的ProQOL3个分量表Cronbach α系数分别为0.864、0.569和0.742,分半信度分别为0.829、0.490和0.677.验证性因子分析模型的x2检验P=0.88,拟合优度指数（GFI）=0.895,调整拟合优合指数（AGFI）=0.912,规范拟合指数（NFI） =0.856,比较拟合指数（CFI） =0.895,近似误差方根（RMSEA）=0.063.对ProQOL-30优化后形成新ProQOL-28量表,其枯竭和创伤/同情疲乏的Cronbach α系数上升为0.616和0.757,验证性因子分析模型的x2检验P=0.91,GFI=0.913,AGFI=0.924,NFI=0.900,CFI=0.913,RMSEA=0.031,研究模型AIC及CAIC均小于独立模型.结论 ProQOL-28在地震心理危机干预者中使用具有较好的信度和效度.
Objective To evaluate the reliability and validity of Professional Quality of Life Scale （ProQOL-30,4th version,30 items） among government staff in the Wenchuan earthquake-stricken areas.Methods A total of 1 175 members of government staff in the Wenchuan earthquake-stricken areas were selected by convenience sampling and required to complete the ProQOL and Self-Reporting Questionnaire （SRQ）.The reliability and validity of the scale was evaluated by correlation analysis,t-test,and confirmatory factor analysis.Results Item-total correlation coefficients of the three subscales were 0.590～0.752,0.389 ～ 0.603,and 0.340～0.647,respectively （P〈0.05）,and the average coefficients were 0.672,0.482,and 0.555,respectively （P〈0.05）.The Cronbach＇s α coefficients of the three subscales were 0.864,0.569,and 0.742,respectively,and the split-half reliabilities were 0.829,0.490,and 0.677,respectively.P value was 0.88 in the chi-square test of confirmatory factor analysis model.Goodness-of-fit indices of ProQOL-30 included GFI=0.895,NFI=0.856,CF1=0.895,RMSEA=0.063,and AGFI=0.912.For the ProQOL-28 as an optimized version of ProQOL-30,the Cronbach＇s α coefficients for burnout and trauma/compassion fatigue increased to 0.616 and 0.757,respectively.P value was 0.91 in the chi-square test of confirmatory factor analysis model test.Goodness-of-fit indices of ProQOL-28 were GFI =0.913,AGFI =0.924,NFI =0.900,CFI =0.913,and RMSEA =0.031.Conclusion ProQOL-28 has good reliability and validity among government staff in the earthquake-stricken areas in China.
