: Smartphone use has been rapidly increasing worldwide, which has brought possible smartphone addiction into the focus of research. In order to identify potential smartphone addicts, several scales were developed to assess smartphone addiction. Among them, the Smartphone Addiction Scale was frequently used. The study aimed to test the reliability and validity of the Serbian version of the SAS-SV and estimate smartphone addiction prevalence among medical students. : The study was conducted in December 2018 on a convenience sample of 323 third-year medical students. The cross-cultural adaptation was performed following the well-established guidelines for cross-cultural adaptation of self-reported measures. Exploratory factor analysis was used to examine the structure of the questionnaire. Factor extraction was performed by principal component analysis with Varimax rotation. For test-retest reliability, students completed the questionnaire twice within seven days. : The Serbian version of the SAS-SV showed good internal consistency (Cronbach's alpha = 0.89) and excellent reliability for test-retest scores (ICC = 0.94, 95% CI = 0.92-0.96). Factor analysis supported the extraction of one factor, which explained 51.538% of the variance. To explore convergent validity furthermore, the SAS-SV was correlated with time indicators of smartphone use. According to cut-off values for the SAS-SV score, 19.5% of students could be regarded as "addicted", and often spent more time on smartphones and social networks on working days and weekends than "not addicted" students. : The Serbian version of the SAS-SV is a reliable and valid instrument for detecting smartphone addiction among university students. Further research on this issue is encouraged to enable a better understanding of this ever-increasing public health issue.
: 智能手机在全球范围内的使用迅速增加，这使得潜在的智能手机成瘾问题成为研究的焦点。为了识别潜在的智能手机成瘾者，已经开发了几种量表来评估智能手机成瘾。其中，智能手机成瘾量表（Smartphone Addiction Scale，SAS）被广泛使用。本研究旨在检验塞尔维亚版 SAS-SV 的信度和效度，并估计医学生中智能手机成瘾的流行率。 : 该研究于 2018 年 12 月在 323 名三年级医学生中进行，采用方便样本。跨文化适应性遵循自我报告量表跨文化适应性的既定准则进行。采用探索性因子分析来检验问卷的结构。因子提取采用主成分分析和 Varimax 旋转。为了检验重测信度，学生在七天内完成了两次问卷调查。 : 塞尔维亚版 SAS-SV 具有良好的内部一致性（Cronbach's alpha = 0.89）和重测信度（ICC = 0.94，95%CI = 0.92-0.96）。因子分析支持提取一个因子，该因子可以解释 51.538%的方差。为了进一步探讨聚合效度，SAS-SV 与智能手机使用的时间指标相关。根据 SAS-SV 得分的截断值，19.5%的学生可以被视为“成瘾”，他们在工作日和周末花在智能手机和社交网络上的时间往往比“非成瘾”学生多。 : 塞尔维亚版 SAS-SV 是一种可靠且有效的工具，可用于检测大学生中的智能手机成瘾。鼓励进一步研究这个问题，以便更好地理解这个日益严重的公共卫生问题。
