在线风险暴露量表在中国大学生中的信效度检验

Reliability and Validity of the Online Risk Exposure Scale in Chinese College Students

目的:基于中国大学生群体考察在线风险暴露量表的信效度。方法:两次共招募1235名大学生,其中第一次招募541名,只作答在线风险暴露量表,第二次招募694名,依次填写在线风险暴露量表、焦虑量表、抑郁量表和社交媒体成瘾量表。1个月后从第二批被试中选取86人进行重测。结果:在线风险暴露量表各条目区分度良好。探索性因素分析和验证性因素分析(χ^(2)/df=4.65,RMSEA=0.073,TLI=0.923,CFI=0.939,IFI=0.939,NFI=0.923)均支持了四因子结构,累计方差贡献率为66.07%。总量表的Cronbach’sα系数和重测信度分别为0.91和0.66。在线风险暴露与焦虑(r=0.49,P<0.01)、抑郁(r=0.46,P<0.01)和社交媒体成瘾(r=0.26,P<0.01)均存在显著正相关。结论:在线风险暴露量表中文版符合测量学标准,可用于测量大学生的在线风险暴露水平。

Objective:To test the reliability and validity of the Online Risk Exposure Scale(ORES)in Chinese college students.Methods:1235 Chinese college students participated in this study.541 participants were asked to complete the ORES for the first time.In the second test,694 participants filled in the ORES,Anxiety Scale,Depression Scale,and Social Media Addiction Scale.A month after the second survey,86 students were followed to complete the Chinese version of ORES.Results:Each item of the ORES had a good discrimination.Both exploratory and confirmatory factor analysis confirmed the four-factor model of the scale(χ^(2)/df=4.65,RMSEA=0.073,TLI=0.923,CFI=0.939,IFI=0.939,NFI=0.923).The cumulative explained variance was 66.07%.The internal consistency reliability coefficient and test-retest reliability coefficient of the scale were 0.91 and 0.66 respectively.The total score of the ORES was positively correlated with anxiety(r=0.49,P<0.01),depression(r=0.46,P<0.01)and social media addiction(r=0.26,P<0.01).Conclusion:The Chinese version of ORES meets the measurement standards and could be used to measure the online risk exposure of college students.
