HIV/AIDS压力量表中文版的信效度检验

The Reliability and Validity of the Chinese Version of the HIV/AIDS Stress Scale

目的:对HIV/AIDS压力量表(SS-HIV)进行初步修订并在HIV感染者/AIDS患者(PLWHA)中进行信效度检验,探讨其在中国文化背景下的适用性。方法:将在中南地区某市级疾病预防与控制中心接受治疗管理服务的PLWHA作为连续样本招募入组,共得到符合入组条件的研究样本376人,采用中文版HIV/AIDS压力量表(CSSHIV)、病人健康问卷抑郁量表(PHQ-9),广泛性焦虑量表(GAD-7)等进行问卷调查。通过项目分析进行条目筛选,采用结构效度、效标效度、区分效度进行效度评价,采用分半信度、重测信度、Cronbachα系数进行信度评价。结果:1项目分析显示在原始量表的基础上剔除1个条目,保留22个条目;2探索性因子分析提示CSS-HIV共提取3个公共因子,累计方差贡献率为55.359%,验证性因子分析发现22条目的中文版量表模型拟合数据最优,各指标为χ2/df=3.066,CFI=0.892,GFI=0.866,NFI=0.849,IFI=0.893,RMSEA=0.074;有HIV相关症状的患者压力得分明显高于无症状者;CSS-HIV压力总分与抑郁得分、焦虑得分的相关系数分别为0.706、0.703。3量表分半信度为0.884,重测信度为0.845,内部一致性系数为0.932。结论:HIV/AIDS压力量表中文版具有良好的信效度,可以用于研究我国PLWHA人群的压力状况。

Objective： To revise the Chinese version of HIV/AIDS Stress Scale（CSS-HIV）, and test its reliability and validity in people living with HIV/AIDS（PLWHA）, and assess its applicability in the Chinese cultural context. Methods： A total of 376 registered PLWHA in Central South Area were recruited by consecutive sampling. The Chinese version of the HIV/AIDS Stress Scale（CSS- HIV）, Patient Health Questionnaire（PHQ- 9）, Generalized Anxiety Disorder Scale（GAD- 7）were used to collect information. The item analyses were applied to examine the discrimination of items. Construct validity,criterion validity, discriminant validity were used to evaluate the validity of the CSS-HIV. Split-half reliability, test-retest reliability, Cronbach α coefficient were used to evaluate its reliability. Results： 1According to the results of the item analysis, 22 items were retained.2The results of exploratory factor analysis showed that the CSS-HIV consisted of three factor,and the total variance explained 55.359%, and the scale had twenty-two-factor model with better fitting indexes of confirmatory factor analysis, χ^2/df=3.066, CFI=0.892, GFI=0.866, NFI=0.849, IFI=0.893, RMSEA=0.074. Patients who had HIVrelated symptoms had significantly higher scores than the asymptomatic patients. The correlation coefficients of CSS-HIV with PHQ-9 and GAD-7 were 0.706 and 0.703. 3The split-half reliability was 0.884, the test-retest reliability was 0.845,and the internal consistency coefficient was 0.932. Conclusion： The Chinese version of the HIV/AIDS Stress Scale has good reliability and validity, which can be used to evaluate the stress of PLWHA in China.
