目的评价简明健康调查量表(SF-36)应用于农村空巢老人生存质量测量时的信度和效度。方法采用中文版SF-36量表,对江苏省徐州市分层整群随机抽取218名农村空巢老人进行面访调查,评价该量表的信度和效度。结果 SF-36量表的分半系数为0.84,生理职能(RP)、生理功能(PF)、躯体疼痛(BP)、总体健康(GH)、精力(VT)、社会功能(SF)、情感职能(RE)和精神健康(MH)8个维度Cronbach’sα系数为0.79、0.88、0.86、0.81、0.77、0.76、0.88、0.77,量表具有良好的分半信度和内部一致性信度;效度分析表明,集合效度和区分效度试验成功率分别为97.14%和97.96%,因子分析(RMSEA=0.12,CFI=0.91),PF、VT、RE、MH 4个维度在因子负荷上与理论模型完全一致;量表反应度评价表明,除RP、BP、SF 3个维度天花板效应分别为42.63%、48.79%、26.45%外,其他维度地板效应和天花板效应均不显著。结论 SF-36量表适用于农村空巢老人生存质量评价,但尚需根据实际情况对部分条目进行完善。
Objective To evaluate the reliability and validity of the Concise Health Survey (SF-36) in measuring the quality of life of empty-nesters in rural areas. Methods A Chinese version of SF-36 scale was used to survey 218 empty nesters in rural areas in Xuzhou, Jiangsu Province. The reliability and validity of the questionnaire were evaluated. Results The half-coefficient of SF-36 was 0.84, and the physical function (RP), physical function (PF), physical pain (BP), total health (GH), energy (VT), social function (RE) and mental health (MH) dimensions of Cronbach’s α coefficient of 0.79,0.88,0.86,0.81,0.77,0.76,0.88,0.77, the scale has a good semi-reliability and internal consistency reliability; Degree analysis showed that the success rates of set validity and discriminant validity test were 97.14% and 97.96% respectively. Factor analysis (RMSEA = 0.12, CFI = 0.91), PF, VT, RE, The model is completely consistent. The evaluation of scale reactivity shows that except for RP, BP and SF, the three-dimensional ceiling effect is 42.63%, 48.79% and 26.45% respectively. However, the floor and ceiling effects are not significant in other dimensions. Conclusion The SF-36 scale is suitable for evaluating the quality of life of empty-nesters in rural areas, but some items still need to be improved according to the actual situation.
