跨性别态度与信念量表中文版测评成年人的效度和信度

Validity and reliability of the Chinese version of the Transgender Attitudes and Beliefs Scale in adults

目的:检验跨性别态度与信念量表(TABS)中文版在普通成年人中的效度与信度。方法:招募年龄≥18岁居民1 656人,按年龄组对等分为样本1和样本2。总样本用于条目分析和内部一致性信度检验;样本1用于探索性因子分析;样本2用于验证性因子分析。在总样本中选取60人间隔2周重测。结果:TABS中文版共26个条目,各条目内容效度指数(I-CVI)在0.83~1.00之间,内容效度指数(SCVI)为0.98;探索性因子分析提取人际舒适性、性别信念、人类价值3个公因子,累计解释总方差为57.13%;验证性因子分析结果显示量表拟合可以接受(χ^(2)/df=2.95,RMSEA=0.05,GFI=0.92,AGFI=0.90)。总量表的Cronbach α系数为0.95,3个因子的Cronbach α系数为0.95、0.88和0.86;总量表的重测信度为0.88,3个因子分别为0.78、0.65、0.91。结论:跨性别态度与信念量表中文版评估普通成年人对跨性别群体态度的效度和信度良好。

Objective:To examine the validity and reliability of the Chinese version of the Transgender Attitudes and Beliefs Scale(TABS)in the general adult population.Methods:A total of 1656 residents aged≥18 years were recruited by convenient sampling method,and were equally divided into sample 1 and sample 2 according to age group.The total sample was used for item analysis and internal consistency reliability test.Sample 1 was used for exploratory factor analysis,Sample 2 was used for confirmatory factor analysis,and 60 residents were selected for retesting at a 2-week interval.Results:The TABS Chinese version included a total of 26 items,with the content validity index(I-CVI)of each item ranging from 0.83 to 1.00,and the content validity index(S-CVI)of the scale being 0.98.Exploratory factor analysis extracted 3 common factors,namely interpersonal comfort,gender beliefs,and human value,with a cumulative total variance of 57.13%.Confirmatory factor analysis showed that the scale fit was acceptable(x^(2)/df=2.95,RMSEA=0.05,GFI=0.92,AGFI=0.90).The Cronbachαcoefficients of the total score of the scale and the scores of the 3 factors were 0.95,0.95,0.88 and 0.86.The retest reliabilities were 0.88,0.78,0.65 and 0.91.Conclusion:The Chinese version of the Transgender Attitudes and Beliefs Scale(TABS)has good validity and reliability in assessing general adults'attitudes toward the transgender community.
