摘要
目的考量《中国大学生亚健康状态测量量表》的结构效度。方法采用结构方程模型的验证性因素分析,对1500名大学生施测以检验分量表和总量表的结构效度,同时采用可靠性分析再次验证量表的内部一致性、稳定性信度。结果总量表和各分量表的一致性系数(α值)在0.803～0.845,12个维度的α值在0.821～0.851,稳定性系数均在0.70以上;3个分量表具有接受度较高的结构效度:卡方值与自由度的比值都小于3.0,TLI、CFI值均超过0.90,RMSEA值介于0.075～0.042,SRMR值都接近0.05;总量表具有接受度更佳的结构效度:χ2/df为2.543;TLI、CFI值均超过0.95;RMSEA值为0.05,SRMR值为0.04。结论量表可靠性强、结构效度佳,可作为我国大学生亚健康状态研究的测量工具。
Objective To assess the construct validity of Chinese University Students＇ Sub-health Scale. Methods A spot trial sam- pling of 1500 individuals was conducted to study the SEM＇s confirmatory factor analysis, test-retest reliability and Cronbach＇s alpha coefficient. Resuits A test-retest reliability was above 0.7 with a Cmnbach＇s coefficient between 0. 821to 0. 851. Proof by the X^2 goodness-of-fit-test such as X^2/df less more 3, TLI and CFI above of 0. 90, RMSEA and SRMR near by 0. 05, the Sub-health Scale has a good construct validity. Conclusion The Chinese University Students＇ Sub-health Scale was tested to be reliable and valid enough to be applicable to measuring college students＇ sub-health.
