本研究旨在分析强迫性互联网使用量表(Cius)和网络成瘾测验(IAT)的心理测量学特性和效度，并确定符合IAT界限的Cius用于发现问题互联网使用的阈值。我们透过不同的招募渠道，招募了292名年龄介乎14-63岁、每个工作日或周末私人上网时间最少1小时的有问题或病态赌博的人士(237名男性，55名女性)。结果表明，两个量表具有较好的内部一致性(Cronbach‘sα=0.9)，并具有良好的收敛效度(r=0.75；95%CI为0.70~0.80)。Cius与每周私人互联网使用时间的相关性(r=0.54)显著高于IAT(r=0.40)。在所有参与者中，25.3%的人根据IAT被归类为问题互联网用户，分界点&>=40。符合分类病例的最高比例来自Cius分界值=18(敏感度79.7%，特异度79.4%)。然而，对于有问题的互联网使用情况的估计，一个更高的分界值(>；=21)似乎更合适。(C)2013年S.Karger AG，巴塞尔
This study aims to analyze psychometric properties and validity of the Compulsive Internet Use Scale (CIUS) and the Internet Addiction Test (IAT) and, second, to determine a threshold for the CIUS which matches the IAT cut-off for detecting problematic Internet use. A total of 292 subjects with problematic or pathological gambling (237 men, 55 women) aged 14-63 years and with private Internet use for at least 1 h per working or weekend day were recruited via different recruitment channels. Results include that both scales were internally consistent (Cronbach's alpha = 0.9) and had satisfactory convergent validity (r = 0.75; 95% CI 0.70-0.80). The correlation with duration of private Internet use per week was significantly higher for the CIUS (r = 0.54) compared to the IAT (r = 0.40). Among all participants, 25.3% were classified as problematic Internet users based on the IAT with a cut-off >= 40. The highest proportion of congruent classified cases results from a CIUS cut-off >= 18 (sensitivity 79.7%, specificity 79.4%). However, a higher cut-off (>= 21) seems to be more appropriate for prevalence estimation of problematic Internet use. (C) 2013 S. Karger AG, Basel
