| 摘 要： | 目的 评估使用SF-12v2量表评价江苏省6县区≥40岁居民生命质量的信度和效度,获取江苏省≥40岁居民的常模参考数据。方法 采用多阶段分层整群抽样的方法,在江苏6个县区调查完成3 583份SF-12v2问卷。使用Cronbach's α和Spearman-Brown折半信度进行信度分析,使用因子分析、集合度和区分度实验进行效度分析。结果 SF-12v2量表12项条目的Cronbach’s α为0.886,删除任1维度后的Cronbach’s α为0.810~0.841,生理总评分和心理总评分的Cronbach’s α为0.767和0.759;Spearman-Brown折半信度为0.795。因子分析结果显示,采用方差最大正交旋转法共提取2个主成分,累计方差贡献率为61.2%。SF-12v2量表的8个维度中,各维度的集合效度下限均高于区分效度的上限,集合效度实验和区分效度实验的成功率均为100%。结论 SF-12v2量表应用于评价≥40岁居民的生命质量具有良好的信度和效度,各维度评分可作为江苏省≥40岁居民生命质量的常模参考数据。

| Abstract: | Objective To evaluate the reliability and validity of SF-12v2 scale evaluating the quality of life of residents aged 40 and over in 6 counties and districts in Jiangsu Province, and obtain the reference data of standard model of residents aged 40 and over in Jiangsu Province. Methods Using a multi-stage stratified cluster sampling method, 3 583 SF-12v2 questionnaires were collected from 6 counties and districts in Jiangsu Province. Reliability was evaluated by Cronbach's α coefficient and Spearman-Brown split-half reliability coefficient, and validity was evaluated by factor analysis, the aggregation test and discrimination test. Results The Cronbach's α coefficient of SF-12v2 scale was 0.886 in 12 items, that of any dimension removed was between 0.810-0.841. The Cronbach's α coefficient of the physical component summary and the mental component summary was 0.767 and 0.759 respectively. Spearman-Brown split-half reliability coefficient was 0.795. The result of factor analysis showed that there were two principal components extracted by the method of the maximum variance orthogonal rotation, and the cumulative variance contribution rate was 61.2%. Among the eight dimensions of SF-12v2 scale, the lower limit of the aggregation test of each dimension was higher than the upper limit of the discrimination test, and the success rate of the aggregation test and discrimination test was both 100%. Conclusion The SF-12v2 scale was reliable and valid to evaluate the quality of life of residents aged 40 and over, and the scores of various dimensions can be regarded as the reference data of standard model for residents aged 40 and over in Jiangsu Province. |
