Internet addiction is a recently recognized condition that has been linked to decreased academic performance, clinical symptoms of depression or anxiety, alongside decreased empathy levels. This study examined the validity and reliability of "the Social Media Addiction Scale - Student Form (SMAS-SF)".
The final Romanian version of the questionnaire was tested in a focus group for the understandability of each question. For confirmatory factor analysis and structural equation modeling, a sample of 649 students was recruited. A subsample of 67 undergraduate students was used to measure reliability by Cronbach's alpha and intraclass correlation coefficient (ICC).
A 2-step confirmatory factor analysis was used and 4 factors emerged, similar to the original questionnaire: virtual tolerance, virtual problems, virtual information, and virtual communication, showing acceptable levels of fit. The structural equation modeling measured the structural relationship between measured variables and latent constructs and acknowledged that the 4-factor model had satisfactory levels for comparative fit index (0.916) and Tucker-Lewis index (0.897), root mean square error of approximation (0.062, with 95% CI between 0.055-0.069), and standardized root mean square residual (0.053). Values of Cronbach's alpha = 0.817 and ICC = 0.829 for the overall 16 item questionnaire were acceptable.
The Romanian version of the SMAS-SF is a reliable and valid tool to measure social media addiction among undergraduate medical students that may be further used in subsequent research.
网络成瘾是一种最近才被认识到的状况，它与学业成绩下降、抑郁或焦虑的临床症状以及同理心水平降低有关。本研究检验了“社交媒体成瘾量表 - 学生版（SMAS - SF）”的有效性和可靠性。
问卷的最终罗马尼亚语版本在一个焦点小组中进行了测试，以检验每个问题的易懂性。为了进行验证性因素分析和结构方程建模，招募了649名学生作为样本。使用67名本科生的子样本通过克朗巴哈系数（Cronbach's alpha）和组内相关系数（ICC）来测量可靠性。
采用了两步验证性因素分析，出现了4个因素，与原始问卷类似：虚拟耐受性、虚拟问题、虚拟信息和虚拟交流，显示出可接受的拟合水平。结构方程建模测量了测量变量与潜在结构之间的结构关系，并确认4因素模型在比较拟合指数（0.916）、塔克 - 刘易斯指数（0.897）、近似误差均方根（0.062，95%置信区间为0.055 - 0.069）和标准化残差均方根（0.053）方面具有令人满意的水平。整个16项问卷的克朗巴哈系数值 = 0.817，ICC = 0.829，均可接受。
罗马尼亚语版的SMAS - SF是一种可靠且有效的工具，可用于测量本科医学生的社交媒体成瘾情况，后续研究中可进一步使用。
