摘要
目的:引进困顿感量表(ES),评价其在医学生群体中的信效度。方法:选取某医学院校学生1768名,将其随机分半,一半(n=855)进行探索性因子分析,另一半(n=913)进行验证性因子分析;采用病人健康问卷9条目(PHQ-9)检验效标效度。间隔1个月后,在总样本中选取53名学生进行重测。结果:探索性因子分析显示量表共16个条目,包含1个公因子,累计方差解释率64.66%,各条目的因子负荷值在0.23~0.77之间;验证性因子分析表明两因子模型拟合情况略优于一因子模型(χ~2/df=7.00,RMSEA=0.08,GFI=0.91,CFI=0.95),各因子负荷在0.48~0.89之间。ES得分与PHQ-9得分呈正相关(ICC=0.44)。总量表的Cronbach α系数为0.96,2个维度的α系数分别为0.94和0.93;总量表的重测信度为0.83,2个维度的重测信度为0.80、0.83。结论:困顿感量表中文版在医学生群体有良好的信效度,可以用于评估该群体的困顿感。
Objective:To evaluate the validity and reliability of the Chinese vision of the Entrapment Scale(ES) in medical students.Methods:Totally 1768 medical students were selected.They were randomly allocated into two groups for exploratory factor analysis(n=855) and confirmatory factor analysis(n=913).All samples were assessed in criterion validity with the Patient Health Questionnaire(PHQ-9).One month later,53 participants were retested.Results:The exploratory factor analysis extracted 1 component from 16 items,and explained 64.66% of the total variance.The factor loading of items ranged between 0.23-0.77.The confirmatory factor analysis verified that the fitting of the two-factor model was slightly better than that of the one-factor model(χ~2/df=7.00,RMSEA=0.08,GFI=0.91,CFI=0.95).The factor loading of items ranged from 0.48 to 0.89.The ES scores were positively correlated with the PHQ-9 scores(ICC=0.44).Cronbach' s α coefficients were 0.96 for the total scale and 0.83 for the test-retest reliability.The internal consistency reliabilities for the 2 factors were 0.94 and 0.93,and the test-retest reliabilities for the 2 factors were 0.80 and 0.83.Conclusion:The Chinese vision of the Entrapment Scale has good validity and reliability among Chinese medical students,and it could be used in the evaluation of entrapment.
