摘要
目的分析SF-12量表评价我国接受ART的HIV/AIDS患者生存质量的信度和效度。方法采用方便抽样选取北京、河南、贵州和安徽接受ART的HIV/AIDS患者,使用自行设计的调查表和SF-12量表收集患者一般情况和生存质量。使用Cronbach’sα系数和Spearman-Brown系数评价量表的信度。利用探索性因子分析方法提取2个公因子作为生理健康总分和心理健康总分,将8个维度与生理健康总分和心理健康总分间的相关性分为高度、中度和低度相关,评价结构效度。通过分析患者CD4细胞数和生存质量得分的关系评价效标效度。通过比较条目与所属维度及其他维度的相关系数大小评价集合效度和区分效度。结果SF-12量表的Cronbach’sα系数为0.857,Spearman-Brown系数为0.849。探索性因子分析结果显示,除情感职能和社会功能外,其余维度与生理健康总分和心理健康总分的相关性与SF-36一致。除生理健康总分外,患者CD4细胞数水平越高,8个维度得分和心理健康总分越高。量表12个条目与所属维度的相关系数均>0.400,且均大于该条目与其他维度的相关系数。结论SF-12量表用以评价我国接受ART的HIV/AIDS患者生存质量的信效度良好,可推广应用于测量我国HIV/AIDS患者的生存质量。
Objective To evaluate the reliability and validity of SF-12 for measuring the quality of life(QoL)among HIV/AIDS patients receiving ART in China.Methods Convenience sampling was used to select HIV/AIDS patients who have received ART in Beijing,Henan,Guizhou and Anhui.A self-designed questionnaire and SF-12 were adopted to collect the general information and QoL of respondents.Cronbach’sαand Spearman-Brown correlation coefficient were used for reliability evaluation.Exploratory factor analysis was selected to extract two characteristic roots as physical component score(PCS)and mental component score(MCS).The relations between every domain and PCS/MCS were classified as highly,moderately and lightly correlated.Criterion validity was evaluated by comparing the QoL scores of patients with different CD4 cells levels.The differences of correlation between each item and its related scale and other scales were compared to evaluate collective validity and discriminant validity.Results Cronbach’sαwas 0.857,and Spearman-Brown correlation coefficient was 0.849.Except for emotional function and social function,the correlation between domains and PCS or MCS was consistent with SF-36.Except PCS,all domains’scores and MCS could distinguish patients with different levels of CD4 cells.The correlation coefficients between each item and its related dimension are greater than 0.400,and greater than the correlation coefficients between item and other dimensions.Conclusions SF-12 has acceptable reliability and validity in measuring Qo L among HIV/AIDS patients receiving ART in China,which can be applied to further study for investigating QoL among HIV/AIDS patients in China.
