认知灵活性问卷中文版测评大学生样本的效度和信度

Validity and reliability of the Chinese version of the Cognitive Flexibility Inventory in college students

目的：分析认知灵活性问卷（CFI）中文版在大学生样本中的效度和信度。方法：选取广东、江西、湖北、浙江四省及北京市的大学生745人完成CFI中文版,并以认知灵活性量表（CFS）、流调中心抑郁量表（CES-D）及简易应对方式问卷（SCSQ）为效标。对数据进行条目分析、验证性因子分析、效标关联效度分析和内部一致性信度及合成信度检验;3周后随机选取其中99名被试进行重测。结果：条目分析显示CFI中文版的20个条目具有良好的区分度;验证性因子分析表明,修订后的问卷结构与原版问卷一致,两因子模型拟合良好（χ^2/df=3.52,CFI=0.90,NNFI=0.89,SRMR=0.06,RMSEA=0.06）;CFI得分与CES-D的抑郁情绪、躯体症状与活动迟滞、人际问题得分及SCSQ的消极应对得分呈负相关（r=-0.36、-0.33、-0.34、-0.26,均P〈0.001）,与CFS得分及CES-D的积极情绪、SCSQ的积极应对得分呈正相关（r=0.72、0.44、0.48,均P〈0.001）;总问卷及可选择性、可控性两个维度的Cronbachα系数与合成信度均在0.80以上,重测信度均在0.65以上。结论：认知灵活性问卷（CFI）中文版在大学生样本中具有良好的测量学性质,可以用于评估大学生的认知灵活性。

Objective：To analyze the validity and reliability of the Chinese version of Cognitive Flexibility Inventory（CFI） in the college students.Methods：Totally 745 college students from Guangdong,Jiangxi,Hubei,Zhejiang Provinces and Beijing City were selected to complete the CFI.The Cognitive Flexibility Scale（CFS）,Center for Epidemiologic Studies Depression Scale（CES-D） and Simplified Coping Style Questionnaire（SCSQ） were administered to test the criterion-related validity.And item analysis,confirmatory factor analysis,criterion-related validity and reliability were evaluated.Totally 99 participants of them were randomly selected after three weeks to calculate test-retest reliability.Results：Item analysis indicated that the 20 items of the Chinese version of CFI had good discrimination.Confirmatory factor analysis showed that the structure of the Chinese version of CFI was the same with the original CFI,and indicated good fit（χ^2/df=3.52,CFI =0.90,NNFI =0.89,SRMR =0.06,RMSEA= 0.06）.The CFI scores were negatively correlated with the scores of CES-D ＂depressed affect＂, ＂somatic symptoms＂, ＂interpersonal problems＂ and SCSQ ＂negative coping＂（r=-0.36,-0.33,-0.34,-0.26,Ps〈 0.001）,and positively correlated with the scores of Chinese version of CFS,CES-D ＂positive affect＂ and SCSQ ＂positive coping＂（r=0.72,0.44,0.48,Ps〈0.001）.Moreover,the Cronbach α coefficient and composite reliability of the total scale and each subscale were above 0.80,and test-retest reliability of total scale and each subscale were above0.65.Conclusion：It suggests that the Chinese version of Cognitive Flexibility Inventory（CFI） has acceptable psychometric quality among Chinese college students,which could be used to evaluate cognitive flexibility in the college students.
