Abstract:
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 that χ2/ 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's α was 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.
