青年醉氧反应问卷的编制及信效度检验

Development and Reliability and Validity Test of Youth Drunken Oxygen Response Questionnaire

目的 编制大学生醉氧反应问卷,以期为长期在高原地区生活的藏汉大学生返回低海拔地区时提供有效的测量工具。方法 于2022年7月份对西藏自治区西藏大学25名近期有过醉氧经历的大学生进行访谈,以此编写问卷题项,再由60名有过醉氧经历的大学生进行青年醉氧反应问卷初测版问卷,根据评定结果建立行为频数表,将频数过低的题项进行删除。并对修改后的问卷进行项目分析、效度检验及信度检验,最终形成正式问卷。结果 大学生醉氧反应问卷共16个题项,项目分析显示,低分组与高分组16个项目区分度比较,差异有统计学意义(P<0.05);通过对200个样本进行探索性因素分析,最终确定15个题项,KMO值为0.905,Bartlett球形检验的χ2值为1786.505,自由度为105,P<0.001;并将各题项归类为4个因子,累积方差解释率为74.315%,分别命名为“行为迟缓”(因子一)、“生理不适”(因子二)、“负面情绪”(因子三)、“正面情绪”(因子四)。验证性因素分析显示,模型的拟合度指标GFI为0.902,NFI为0.913,CFI为0.956,IFI为0.957,TLI为0.945,RMSEA为0.068。效度分析显示,4个因子对应CR值均高于0.7,HTMT值均小于0.85,且4个因子的MSV和ASV指标均小于AVE。信度分析显示,问卷的Cronbach’s α系数和分半信度系数分别为0.91、0.85。结论 大学生醉氧问卷的4个维度设置合理,具有较高的信度和效度,符合心理测量学的要求。

Objective To develop a questionnaire of drunken oxygen response of college students,and to provide an effective measurement tool for those Tibetan and Han college students who have lived in plateau area for a long time when they return to low altitude area.Methods In July 2022,25 college students with recent drunken oxygen experience in Tibet University of Tibet Autonomous Region were interviewed to prepare the questionnaire items,and then 60 college students with drunken oxygen experience conducted the preliminary test version of the youth drunken oxygen response questionnaire.According to the evaluation results,the behavior frequency table was established,and the items with too low frequency were deleted.The revised questionnaire was subjected to project analysis,validity test and reliability test,and finally a formal questionnaire was formed.Results There were 16 questions in the questionnaire of oxygen response of college students.The item analysis showed that there was a statistically significant difference in the discrimination of 16 questions between the low score group and the high score group(P<0.05).Through exploratory factor analysis of 200 samples,15 questions were finally determined,and the KMO value was 0.905,the chi-square value of Bartlett's spherical test was 1786.505,the degree of freedom was 105,and the P value was less than 0.001.The items were classified into four dimensions,and the cumulative variance interpretation rate was 74.315%,which were named slow behavior(factor 1),physiological discomfort(factor 2),negative emotion(factor 3),positive emotion(factor 4).Confirmatory factor analysis showed that the GFI,NFI,CFI,IFI,TLI and RMSEA of the model were 0.902,0.913,0.956,0.957,0.945 and 0.068,respectively.Validity analysis showed that the CR values of the four factors were higher than 0.7,the HTMT values were less than 0.85,and the MSV and ASV indexes of the four dimensions were less than AVE.The reliability analysis showed that the Cronbach'sαcoefficient and split-half reliability coefficient of the questionnaire were 0.91 and 0.85,respectively.Conclusion The four dimensions of the questionnaire are reasonable that have high reliability and validity,and meet the requirements of psychometrics.
