大学生问题性短视频媒体使用量表的初步编制

Preliminary development of problematic short video media use scale for university students

目的编制适用于中国文化背景下的大学生问题性短视频媒体使用量表,并检验其信效度。方法在文献检索、访谈法和问卷法基础上建立问卷项目;选取275名大学生作为被试进行项目分析和探索性因素分析,以642名大学生作为被试进行验证性因素分析和信效度分析。1个月后对112名大学生进行重测,搜集量表重测信度资料。采用SPSS 26.0和Mplus 8.3软件对数据进行相关分析、信度和效度统计分析。结果(1)正式问卷包含3个维度,共13个项目,3个维度分别是知行变化维度、生理不适维度和社会粘度维度,内部一致性系数分别为0.794、0.820和0.716,项目负荷在0.577~0.805之间,方差贡献率为64.803%。(2)采用Mplus 8.3进行验证性因素分析,结果(χ2/df=2.390,SRMR=0.038,RMSEA=0.047,CFI=0.970,TLI=0.963)表明3因素结构符合心理学测量学要求。(3)问卷分半信度=0.885,Cronbach'sα=0.882,1个月后重测信度=0.991。总问卷与各维度内部一致性信度在0.716~0.882之间。结论本研究编制的大学生问题性短视频媒体使用量表具有较好的心理测量学指标,可以用于中国大学生群体中问题性短视频使用的研究。

Objective To develop the problematic short video use scale for college students in the context of Chinese culture,and to test its reliability and validity.Methods The questionnaire items were established based on bibliographic retrieval method,interviewing method and social investigation method.Totally 275 college students were selected as subjects for item analysis and exploratory analysis,and 642 college students were selected for confirmatory factor analysis,validity analysis and reliability analysis.One month later,112 college students were retested and test-retest reliability data were collected.SPSS 26.0 and Mplus 8.3 softwares were used for correlation analysis,reliability and validity analysis of the questionnaires.Results(1)The formal questionnaire contained three dimensions,13 items in total,and the three dimensions were change of knowledge and behavior,physical discomfort and social viscosity.The internal consistency coefficients of three dimensions were 0.794,0.820,and 0.716,respectively.The item load ranged from 0.577 to 0.805,and the variance contribution rate was 64.803%.(2)The confirmatory factor analysis results showed thatχ2/df=2.39,SRMR=0.038,RMSEA=0.047,CFI=0.970,TLI=0.963,indicated that the three-factor structure accords with the requirements of psychometrics.(3)The split-half reliability of the questionnaire was 0.885,Cronbach'sαwas 0.882,and the test-retest reliability after one month was 0.991.The internal consistency reliability of the total questionnaire and each dimension ranged 0.716-0.882.Conclusion The problematic short video media use scale has good psychometric indicators and it benefits the studies of problematic short video use among Chinese college students.
