目的评价SF-36量表在测量地震伤残人员生存质量中的信度和效度。方法利用自填法及访谈相结合的方式调查201例绵竹市某镇地震伤残人员,用重测信度和Cronbach’sα系数分析SF-36信度;因子分析方法分析效度。结果 SF-36各领域的重测信度分别为:生理功能(PF)0.78、生理问题对功能的限制(RP)0.85、躯体疼痛(BP)0.92、健康总体评价(GH)0.82、活力(VT)0.77、社会功能(SF)0.71、心理问题对功能的限制(RE)0.79、精神健康(MH)0.66;各领域的Cronbach’sα系数分别为:PF 0.89、RP 0.75、BP 0.84、GH 0.86、VT 0.78、SF 0.72、RE0.86、MH 0.50。因子分析共提取了6个主成分,基本反映了量表的8个维度,与量表的结构构思基本相符。结论自填法及面对面访谈相结合的方式,将SF-36量表用于该地地震伤残人员生存质量测定具有较好的信度和效度。
Objective To evaluate the reliability and validity of the SF-36 scale in measuring the quality of life of earthquake victims. Methods Totally 201 earthquake-disabled persons in a town in Mianzhu City were surveyed by means of self-filling and interviews. SF-36 reliability was analyzed by using test-retest reliability and Cronbach’s α coefficient. Factor analysis was used to analyze the validity. Results The test-retest reliability of each field of SF-36 were 0.78 for physiological function (PF), 0.85 for physiological function (RP), 0.92 for somatic pain (BP), 0.82 for total health assessment (GH) ) 0.77, 0.71 for social function (SF), 0.79 for mental function (RE), and 0.66 for mental health (MH). The Cronbach’s alpha coefficients in each field were PF 0.89, RP 0.75, BP 0.84, GH 0.86, VT 0.78, SF 0.72, RE 0.86, MH 0.50. A total of six principal components were extracted from the factor analysis, which basically reflected the eight dimensions of the scale, basically consistent with the structure concept of the scale. Conclusion The combination of self-filling method and face-to-face interview shows that the SF-36 scale has good reliability and validity for measuring the quality of life of earthquake-disabled people in this area.
