Due to a growing need for the assessment of excessive Internet use and its potentially adverse effects, many Internet addiction assessment instruments have been developed. The aim of the present study was to analyse the factorial structure and psychometric properties of the Croatian version of one of the most commonly used instruments in this area, the Compulsive Internet Use Scale (CIUS). Data was collected in Croatia as part of the European School Survey Project on Alcohol and Other Drugs (ESPAD) in 2015 with students turning 16 years in the year of data collection (n=2558). To evaluate the factorial structure of the CIUS, four models were tested using confirmatory factor analysis. A one-factor model with five correlated errors demonstrated overall best fit. The Croatian version of the 14-item CIUS demonstrated high internal consistency. There was a statistically significant and positive correlation between the CIUS and Internet use time, and a higher score on the CIUS was correlated with higher self-perceived problems related to social media use and gaming. This study demonstrated that the Croatian version of the CIUS offers high construct validity and reliability and can be adequately used in assessing unspecific compulsive Internet use among adolescents. Additionally, results support the use of shortened forms of the CIUS.

由于越来越需要评估过度使用互联网及其潜在的不良影响，因此已经开发了许多互联网成瘾评估工具。本研究的目的是分析该领域最常用的工具之一，即强迫性互联网使用量表（CIUS）的克罗地亚语版本的阶乘结构和心理计量学特性。作为2015年欧洲酒精与其他药物学校调查项目（ESPAD）的一部分，在克罗地亚收集了数据，学生在数据收集的那年已满16岁（n = 2558）。为了评估CIUS的阶乘结构，使用验证性因子分析测试了四个模型。具有五个相关误差的单因素模型显示出整体最佳拟合。14项CIUS的克罗地亚语版本显示出很高的内部一致性。CIUS与互联网使用时间之间存在统计上显着的正相关，CIUS得分越高与社交媒体使用和游戏相关的自我认知问题越高。这项研究表明克罗地亚语版本的CIUS具有很高的结构效度和可靠性，可充分用于评估青少年对非强制性互联网的使用情况。此外，结果支持使用简化形式的CIUS。这项研究表明，克罗地亚版本的CIUS具有很高的结构效度和可靠性，可充分用于评估青少年对非特定性强迫性互联网的使用。此外，结果支持使用简化形式的CIUS。这项研究表明，克罗地亚版本的CIUS具有很高的结构效度和可靠性，可充分用于评估青少年对非特定性强迫性互联网的使用。此外，结果支持使用简化形式的CIUS。
