【摘要】 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’s α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’s α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。
【Abstract】 Objective To evaluate the validity and reliability of the MOS-36-item Short Form of Health Survey (SF-36) measuring the quality of life (QOL) of disabled people injured in the earthquake. Methods A total of 201 disabled people injured in the earthquake in a town of Mianzhu city were investigated via questionnaire combined with a face-to-face interview. The reliability of the SF-36 was assessed by test-retest reliability and Cronbach’s α coefficient. The validity was assessed through factor analysis. Results The test-retest reliability of the SF-36 included: physical functioning (PF) 0.78, role limitation due to physical problems (RP) 0.85, body pain (BP) 0.92, general health (GH) 0.82, vitality (VT) 0.77, social functioning (SF) 0.71, role limitation due to emotional problems (RE) 0.79, and mental health (MH) 0.66. The Cronbach’s α coefficients were as the follows: PF 0.89, RP 0.75, BP 0.84, GH 0.86, VT 0.78, SF 0.72, RE 0.86, and MH 0.50. Six principal components were extracted by factor analysis and the constructs of the obtained instrument were consistent with the conceived concept in essence. Conclusion The SF-36 survey could measure the QOL in disabled people injured in the earthquake with better reliability and validity by questionnaire combined with a face-to-face interview.
