Abstract

Smartphone addiction has become a global concern due to its potential negative impacts. Many tools and questionaires have been developed to assess the current status of smartphone addiction, with the Smartphone Addiction Scale - Short Version (SAS-SV) being one of the most prominent. This study aimed to standardize the Vietnamese version of the Smartphone Addiction Scale - Short Version (SAS-SV) and evaluate its reliability and validity among 803 students at Hanoi Medical University. The study showed that the Vietnamese version of the scale was validated by an expert panel with a Content Validity Index (CVI) of 1. The internal consistency reliability is high, with a Cronbach’s alpha coefficient of 0.875. Pearson correlation analysis was employed to assess the linear relationships between the items as well as between each item and the total score of the scale. Confirmatory Factor Analysis (CFA) was conducted to evaluate the fit of the proposed measurement model. Pearson correlation analysis demonstrated strong relationships among items and between each item and the total scale score. Confirmatory Factor Analysis (CFA) indicated that the model had an acceptable fit to the data: χ²/df = 4.454, CFI = 0.965, TLI = 0.946, and RMSEA = 0.066 (90% CI [0.050, 0.065]). The factor loadings are all greater than 0.50 and statistically significant (p < 0.001), confirming the convergent validity of the scale. Furthermore, the Composite Reliability (CR) and Average Variance Extracted (AVE) both meet the required thresholds, demonstrating the scale's high reliability and good discriminant validity.
