目的评价SF-36健康调查问卷应用于社区老年人群调查的效度和信度。方法面对面访谈的方式调查378名老年人，观察各条目得分，利用条目内部一致性、Cronbach's α系数等评价效度和信度。结果各条目得分的聚类顺序与假定顺序基本一致；除SF标度外，各标度的区分效度、结构效度和信度均较好。结论 SF-36健康调查问卷基本适用于社区老年人群的生命质量评价，但某些条目应进行适当的调整。

Evaluation of reliability and validity of SF-36 Health Survey in old people in community

Objectives　To evaluate the reliability and validity of SF-36 in old people in community. Methods　 378 old people in community were investigated by SF-36 by face-to-face interview, and the score of items was analyzed.Reliability and validity of SF-36 were evaluated by item-internal consistency,item discriminant vadility,Cronbach's alpha coefficient, et al. Results　The clustering and ordering of the item means of SF-36 were the same as that hypothesized, except for items PF2,PF10,RP3,GH4. The correlation between an item and its hypothesized scale was 0.4 or above for all items. The Cronbach's alpha coefficient were above the standard of 0.7 for all except SF scale. Conclusions　SF-36 Health Survey Questionnaire is available for the elderly people. The present evaluation proposes some minor word and item changes which is more suitable for old people.
