AIM: This research is designed to adapt the Smartphone Addiction Scale-Short Version (SASS-SV) to Indonesian version based on cultural adaptation of the rating scale. METHODS: This study involves 300 participants consisted of 151 of male children and 149 female children with an average age is 13.27 years-of-old. The validity of concurrent was used to obtain the validity, while the internal consistency and Receiver Operating Characteristic (ROC) were conducted to confirm the reliability of the rating scale. RESULTS: In purpose to measure internal consistency, the Cronbach alpha has been applied. The Cronbach alpha value was 0.740, and Concurrent validity was checked to NMP the Nomophobia Questionnaire (NMP-Q) based on Indonesian version. The analysis of ROC showed that the value of Area under the Curve (AUC) was 0.997 (0.990-1.000), with cut-off value accounted for ≥ 32, a sensitivity value of 0.91 and specificity value was 0.973 for the male children. On the hand of female children, the results showed similarity with the AUC was 0.996 (0.998-1.000), and the cut-off, sensitivity and specificity values were accounted for ≥ 34, 0.91, and 0.974 respectively. CONCLUSION: The Indonesian version of SAS-SV provided acceptable validation results as well as the reliability, and this version can be used to evaluate the smartphone addiction in Indonesia.
