目的编制用于测定中国HIV感染者生命质量的量表,评价其信度和效度。方法参考现有量表,并与相关专家、基层疾病预防控制人员、HIV感染者进行访谈以形成初始量表,在443例HIV感染者中试用。根据条目应答率、因子分析、相关系数矩阵、内部一致性分析等进行条目精简,形成最终量表。分析最终量表的信度和效度。结果形成的中国HIV感染者生命质量量表(QOL- CPLWHA)共44个条目。各维度没有严重的天花板效应和地板效应(最高为21.0%),内部一致性信度系数均≥0.70,全量表的为0.90。量表总分2周重测信度系数为0.80,有2个维度的重测信度系数低于0.6,4个维度的在0.6～0.7之间。各条目的成维率均为100%。量表总得分与SF-36总得分的spearman相关系数为0.69。结论所形成的QOL-CPLWHA量表首次引入了敌意心理趋势维度。量表具有较好的内部一致性信度、结构效度及内容效度等,可应用于中国HIV感染人群。
Objective To prepare a scale for measuring the quality of life of HIV-infected people in China and evaluate their reliability and validity. Methods According to the existing questionnaire, interviews were conducted with relevant experts, grassroots disease prevention and control personnel and HIV-infected persons to form the initial scale, which was tested in 443 HIV-infected patients. According to the entry response rate, factor analysis, correlation coefficient matrix, internal consistency analysis, etc. to streamline the entries to form the final scale. Analyze the reliability and validity of the final scale. As a result, a total of 44 articles of the QOL-CPLWHA in China were formed. There were no serious ceiling effects and floor effects (up to 21.0%) for each dimension, with an internal consistency reliability coefficient of ≥0.70 and a full scale of 0.90. The total score of two weeks test retest reliability coefficient of 0.80, two dimensions of the test retest reliability coefficient of less than 0.6, four dimensions between 0.6 to 0.7. The dimensionality of each item is 100%. The spearman correlation coefficient between the total score of the scale and the total score of SF-36 was 0.69. Conclusions The QOL-CPLWHA scale formed for the first time introduced a hostile psychological trend dimension. Scale has good internal consistency reliability, structural validity and content validity, which can be applied to HIV-infected people in China.
