摘　　要：目的考评第2代亚健康调查表的信度与效度,总结其测量结果,为进一步研制亚健康量表提供基础依据。方法采用现场调查方式,由被访者本人填写该问卷,收回有效问卷5599份。采用世界卫生组织生存质量简表(WHOQOL-BREF)作为效度参考;分析调查表的结构效度、效标关联效度、区分效度和内部一致性信度。结果(1)效度分析:结构效度采用探索性因子分析法,按特征根值>1提取其因子,共提取16个因子;累及贡献率为52.46%:与WHOQOL-BREF的相关系数为0.693;大学生亚健康人群的调查表总分及各领域分值均高于大学生健康人群(114.81±27.66),(80.51±25.45);(46.76±14.80),(30.61±12.42);(37.43±10.09),(26.97±8.90);(27.12±7.22),(20.37±6.97),P<0.000,显示区分效度较好。(2)信度分析:通过内部一致性信度检验,总的克朗巴赫α系数为0.949;其躯体、心理、社会3大领域的克朗巴赫α系数分别为0.905,0.884,0.855;有12个因子的克朗巴赫α系数达到0.7以上。结论第2代亚健康调查表具有较好信度;其结构效度虽然证实了理论构想,但尚不够理想,可用于亚健康评价的研究。Objective To test reliability and validity of the - second - generation subhealth questionnaire. Methods Though field survey, the questionnaire was filled in by the subjects. The reliability and validity of the second - generation subhealth questionnaire was tested using data from a sample of 5599 undergraduate students. The constructive validity was evaluated with factor analysis. Results There were 16 factors wtih the eigenvalue above 1. The cumulative proportion was 52.46 %. The correlation of the questionnaire total score with the score of WHOQOL - BREF was high （ 0. 693 ）. There were significant differences in mean scores between the undergraduate students of health and subhealth in the domains. So the questionnaire had a high distinguishability validity. By the test of internal consistency method of reliability, the domains of body, mood, society had high reliability above 0.8 ;the Cronbach＇s alpha of the total questionnaire was 0. 905. Conclusion The questionnaire has a good reliability and can be used in the study of subhealth.
