The objectives of this study were to analyze the psychometric properties of the Smartphone Addiction Scale - Short Version (SAS-SV) as follows: (i) the factor structure of the SAS-SV using different statistical methods; (ii) the evidence of convergence; (iii) the temporal stability of the SAS-SV; and (iv) predictive SAS-SV validity. A total of 451 adolescents participated in this study (age M = 13.1; SD = 1.22) by completing a sociodemographic questionnaire (including items evaluating the perception of smartphone use), the Internet Addiction Test (IAT), and the SAS-SV. It was found that 53.2% demonstrated problematic smartphone use. The SAS-SV showed good reliability (alpha = 0.81; omega = 0.78), and all of its items were kept. The network analysis indicated that the items evaluating the withdrawal and preoccupation symptoms had the greatest influence on the network. The intraclass correlation coefficient was 0.846 and indicated good temporal stability of the SAS-SV 20-30 days after the first application. The receiver operating characteristic (ROC) curve analysis indicated 33 points as the best cutoff for the SAS-SV (AUC = 0.739; sensitivity = 65.37%; specificity = 72.26). The instrument also showed a moderate correlation with the variables related to smartphone use (time spent on smartphones, number of messages sent and received, and number of times the smartphone is checked). These data indicate that the SASSV may be a reliable instrument for use with Brazilian adolescents.
