SF-36健康调查量表中文版的研制及其性能测试

Development and psychometric tests of a Chinese version of the SF-36 Health Survey Scales

目的 研制SF 36健康调查量表中文版并验证量表维度建立及记分假设、信度和效度。方法 采用多阶段混合型等概率抽样法 ,用SF 36健康调查量表中文版对 10 0 0户家庭的居民进行自评量表式调查 ;参照国际生命质量评价项目的标准程序 ,进行正式的心理测验学试验。结果 在收回的 1985份问卷中 ,18岁以上的有效问卷 1972份 ,其中应答者 16 88人 (85 6 % ) ,1316人回答了所有条目 ,372人有 1个或以上的缺失答案 ,无应答者中文盲、半文盲占 6 5 5 %。等距假设在活力 (VT)和精神健康 (MH)维度被打破了 ,按重编码后值计算维度分数 ;条目集群的分布接近源量表及其他 2个中文译本 ;除了生理功能 (PF)、躯体疼痛 (BP)、社会功能 (SF)维度 ,其余维度有相似的标准差 ;除了SF、VT维度 ,其余 6个维度条目维度相关一致 ;除了SF维度 ,7个维度集合效度成功率范围为 75 %～10 0 % ,区分效度成功率范围为 87 5 %～ 10 0 %。一致性信度系数除了SF、VT维度 ,其余 6维度变化范围为 0 72～ 0 88,满足群组比较的要求。两周重测信度变化范围为 0 6 6～ 0 94。因子分析产生了 2个主成分 ,分别代表生理健康和心理健康 ,解释了 5 6 3%的总方差。结论 为SF 36健康调查量表适用于中国提供了证据 ,已知群效度试验将为量表效度提?

Objective To develop and evaluate scaling and scoring assumptions, and the reliability and the validity of a Chinese version of the SF 36 scales Methods A multi stage mixed sampling procedure was used to select a representative sample of the general population The sample size was 1 000 households All family members of a selected household, aged 18 and older, completed a survey by self administration Formal psychometric methods for testing assumptions underlying item scoring and scale construction were used according to the standard procedure of the IQOLA Project Results Of the 1 985 collected questionnaires, 1 972 were qualified Of them, 1 688 (85 6%) were respondents 1 316 respondents answered all 36 items, while the remaining (372 respondents) answered with one or several missing responses Among the non respondents, 65 5% were illiteracy or quasi illiteracy The assumption of equal intervals was violated for the VT and MH scales The recoded item values were used to calculate scale scores The clustering and ordering of the item means were approximately the same as that of the source version and other two Chinese versions The items in each scale had similar standard deviations except those in the PF, BP, SF scales The correlations between an item and its hypothesized scale were identical for all except the SF and VT scales The scaling success rates of convergent validity were 0% for the SF scale, 75% for the VT scale, and 100% for the other six scales The scaling success rates of discriminat validity ranged from 87 5% to 100% for all scales except for the SF scale The Cronbach′ α coefficients of internal consistency reliability ranged from 0 72 to 0 88, which were satisfactory for group comparison except 0 39 for the SF scale and 0 66 for the VT scale The two weeks test retest reliability coefficient ranged from 0 66 to 0 94 Factor analysis identified two principal components: a 'physical' factor and a 'mental' factor Taken together, these two factors could be used to explain 56 3% of the total variance Conclusion The Chinese version of the SF 36 Health Survey Scale has achieved conceptual equivalence and satisfied the psychometric scaling assumptions well enough to warrant wide use in China Known groups validity will give more meaningful evidences of the validity of the Chinese SF 36 scales
