摘要
目的探讨SF-12生活质量简表在经济薄弱地区农村居民中应用的信度和效度。方法2019年7月采用分阶段随机抽样法,在苏北地区随机抽取27个经济薄弱村,根据纳排标准选取703例农村居民作为研究对象。运用一般情况量表、抑郁筛查量表(the patient health questionnaire9,PHQ9)和SF-12生活质量简表对其进行问卷调查。采用Cronbach’sα系数和Spearman-Brown折半信度系数评价量表的信度,通过因子分析评价SF-12的结构效度、集合效度和区分效度。比较不同特征人群SF-12得分的区分度,评价PHQ9得分与SF-12得分的相关性。结果SF-12量表总Cronbach’sα系数为0.805,Spearman-Brown折半系数为0.840。KMO=0.861,Bartlett’s球形检验P<0.01。通过主成分分析法提取出2个公因子,分别为身体健康(physical component summary,PCS)和心理健康(mental component summary,MCS);验证性因子分析模型拟合指标χ^(2)/df=1.752,近似误差均方根(root mean square error of approximation,RMSEA)=0.033,集合效度、区分效度定标试验成功率为100%。不同年龄段PCS得分差异有统计学意义(P<0.01),个人年收入、是否为贫困户、是否有抑郁症状PCS、MCS得分差异均有统计学意义(均P<0.01)。PHQ9得分与PCS、MCS得分的相关系数分别为-0.294、-0.512(均P<0.01)。结论SF-12量表应用在经济薄弱地区农村居民中的信度和效度良好,对不同特征人群有较好的区分度,适用于低收入农村居民,个别条目可相应调整。
Objective To investigate the reliability and validity of SF-12 quality of life short form in measuring quality of life among rural residents in economically weak areas.Methods In July 2019,a multistage random sampling method was adopted to randomly select 27 economically weak villages in northern Jiangsu province,and 703 rural residents were selected as the research objects according to the exclusion criteria.The questionnaire survey was carried out using the General Situation Scale,the depression screening scale of the patient health questionnaire 9(PHQ9)and the SF-12 quality of life short form.Cronbach'sαcoefficient and Spearman-Brown split reliability coefficient were used to evaluate the reliability of the scale.The structural validity,aggregate validity and discriminative validity of SF-12 were evaluated by the factor analysis.The differences of SF-12 scores among people with different characteristics were compared,and the correlation between PHQ9 scores and SF-12 scale scores was evaluated.Results The total Cronbach'sαcoefficient of the SF-12 scale is 0.805.The Spearman-Brown half-coefficient is 0.840.KMO=0.861,Bartlett's sphere test showed P<0.01.Two common factors were extracted by principal component analysis,named as physical component summary(PCS)and mental component summary(MCS).Confirmatory factor analysis showed thatχ^(2)/df=1.752,the root mean square error of approximation(RMSEA)=0.033,and the success rate of the aggregate validity and discriminative validity calibration test was 100%.There was statistically significant difference in PCS score among different age groups(P<0.01),and there were statistically significant differences in PCS score and MCS score among the residents in different personal annual income,whether they are poor households,and whether there are depressive symptoms(all P<0.01).The correlation coefficient between PHQ9 score and PCS and MCS score was-0.294 and-0.512 respectively(both P<0.01).Conclusion The SF-12 scale has good credibility and validity among rural residents in economically weak areas,and has good differentiation degree for different characteristic groups,which can be applied to low-income rural residents,and the individual items may be adjusted accordingly.
