摘要
目的评价SF-36量表在老年一般人群的信度和效度。方法采用SF-36生存质量量表,由经过统一培训的调查员对济南市60岁及以上的老年人1386人进行面对面访谈,并计算8项内容的评分。信度包括重测信度、分半信度和内部信度;效度包括判别效度和结构效度。采用相关分析、信度分析和因子分析方法对SF-36量表的信度和效度进行评价。结果各项重测信度的组内相关系数(ICCs)均>0.5;各项分半信度系数均>0.7;各项内部信度的Cronbach'a系数均>0.70。在判别效度的评价中,实际结果与理论推断和以往研究结果相一致,表明量表的判别效度较好;在结构效度的评价中,因子分析所产生的两个公共因子可解释总变异的66.25%,并在相应项目上有较强的因子负荷,表明量表的结构效度较好。结论SF-36量表具有较好的信度和效度,适于评价老年一般人群的生存质量。
Objective:To test the validity and reliability of 'the Short-Form 36 Health Survey Scale′(SF-36) among the country-dwelling elderly population.Method:1386 elderly people were face-to-face interviewed with the SF-36 by the investigators who were trained in advance and the score of eight items was analyzed.Reliability included test-retest reliability,split-half reliability and internal consistency.Validity included discriminatory validity and structure validity.The reliability and validity of the SF-36 were evaluated with correlation analysis,reliability analysis and factor analysis.Result:All test-retest reliability internal correlation coefficients(ICCs) were above 0.5; All the split-half reliability coefficients were above 0.7; All the internal consistency Cronbach′a coefficients were above 0.70.The actual results were consistent with theoretical inference and previous study results,which prove the SF-36 has preferable discriminatory validity.Two common factors were extracted by factor analysis, which accounted for 66.25% of total variance and the factor loads of two common factors were relatively powerful in related items, so the SF-36 had satisfactory structure validity.Conclusion: The Short-Form 36 Health Survey Scale (SF-36) has better reliability and validity, which is available for the evaluation of life quality among elderly people.
