Validation of the Chinese version of the Smartphone Distraction Scale

The Smartphone Distraction Scale (SDS) is a novel assessment scale for smartphone distraction; it comprises 16 items that cover attention impulsiveness, online vigilance, multitasking, and emotion regulation. This study aimed to investigate the validity and reliability of the SDS in college students in China. After translating and culturally adapting the original version of the SDS into Chinese, the scale was tested on a sample of 1302 college students.The validity and reliability were assessed utilizing SPSS 25.0, AMOS 25.0 and Mplus 8.3. Parallel analysis, Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were performed for the validity analysis. Criterion-related validity for the SDS was tested by correlation analysis with the mobile phone addiction scale (MPAI). The reliability analysis was tested by Cronbach's alpha coefficients and intraclass correlation coefficients (ICC). EFA and parallel analysis revealed a three-factor structure. The EFA identified factor loadings on three factors (14 items), explaining a total variance of 60.73 %. The CFA model fit was good (χ²/df = 4.644, RMSEA = 0.047, GFI = 0.930, CFI = 0.955, SRMR = 0.047), and the multigroup confirmatory factor analysis indicated measurement invariance for gender. Both convergent and discriminant validity were established. The criterion-related validity was established based on a significant correlation (r = 0.758) with the MPAI. The Cronbach's alpha coefficient was 0.916, and the split-half reliability was 0.769, demonstrating a satisfactory internal consistency. The score of ICC was 0.907, demonstrating the stability of the SDS. Based on these data, the Chinese version of the SDS demonstrated satisfactory validity and reliability in a sample of college students.
