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.
ABSTRACT
Objective:To explore the latent categories of short video media use tendency among adolescents and the influence of personality traits on different categories.Methods:Totally 1 362 adolescents were tested by the five factors of adolescent personality questionnaire and the problematic short video media use scale in March 2022.SPSS 26.0 software was used for data collation and descriptive statistics.Mplus 8.3 software was used for latent profile analysis (LPA) to explore the latent categories of adolescents’ short video media use tendency.Regression mixed model (R3STEP) was used to explore the relationship between different categories of short video media use tendency and personality traits.Results:The short video media use tendency among adolescents was divided into 4 latent categories (by proportion from low to high): " problematic short video media use tendency type" (C4, 11%), " safe short video media use tendency type" (C3, 21%), " social short video media use tendency type" (C1, 29%), and " transitional short video media use tendency type" (C2, 39%). Different personality traits had different effects on the 4 latent categories of short video media use tendency, and using C3 as a reference, openness ( OR=1.95) was a triggering predictor of C1, neuroticism ( OR=0.72) was a protective predictor of C1; cautiousness ( OR=0.46) was a protective predictor of C2, neuroticism ( OR=1.60) was a triggering predictor of C2; cautiousness ( OR=0.33) was a protective predictor of C4, neuroticism ( OR=3.24) was a triggering predictor of C4. Conclusion:There are four different latent categories of Chinese adolescents' short video media use tendency, respectively " safe" , " social" , " transitional" and " problematic" . Further research reveal that, personality traits have a significant impact on the different categories of adolescents' short video media use tendency.This study suggests that educators reasonably guide " transitional" , intervene " problematic" , and focus on helping adolescents with high neuroticism to effectively regulate their negative emotions and reduce the occurrence of problematic short video use.
ABSTRACT
Objective To evaluate the validity and reliability of social avoidance and distress scale (SAD) for conforming it' s applicability in Mongolian college students.Methods Social avoidance and distress scale (SAD)security scale (SQ),self-esteem scale (SES) and life satisfaction scale (AULC) was used to measure 399 undergraduates whose can understand Mongolian and Chinese language.Results The total scale reliability was 0.872,avoidance scale was 0.726,distress scale was 0.742,total scale heavy reliability (r) was 0.86,avoidance scale (r) was 0.789,distress scale (r) was 0.814.(2)the confirmatory factor analysis verified the effectiveness of the structure,the revised model fitting index x2/df=4.864,NFI =0.92,TLI =0.90,GFI =0.90,IFI =0.87,GFI =0.92,AGFI =0.93,RMSEA =0.06,model fitting was better.(3) There was a significant positive correlation between avoidance scale and distress scale (r=0.634,P＜0.01),and there was a negative correlation (r=0.202-0.499,P＜0.01) between avoidance scale and SES,SQ and AULC.There was a negative correlation between distress scale and SES,SQ and AULC (r=0.192-0.556,P＜0.01).Conclusion SAD (Chinese version) has a good reliability and validity in Mongolian college students.
