Three versions of the Cognitive Screening Test (CST), varying in length from seven to 20 items, are compared using the original data. The shortest version, the CST-7, is not inferior to the longer CST-14 and CST-20. Various psychometric properties are compared. According to the Mokken nonparametric IRT scaling technique, all three CST versions can be considered unidimensional. The Mokken scaling indices H and rho hardly differ in the three versions of the CST. The alpha indices from Classical Test Theory are also very comparable, as is the very good sensitivity and specificity (around 95%). Age and gender have no significant effect on the classification success of the CST-7. Cross-validation of the promising properties of this very short screening instrument is recommended.
使用原始数据对认知筛查测试（CST）的三个版本进行了比较，这三个版本的长度从7项到20项不等。最短的版本CST-7并不逊色于较长的CST-14和CST-20。对各种心理测量特性进行了比较。根据莫肯非参数IRT量表技术，所有三个CST版本都可被视为单维的。CST三个版本的莫肯量表指数H和rho几乎没有差异。经典测试理论的阿尔法指数也非常具有可比性，敏感性和特异性也非常好（约95%）。年龄和性别对CST-7的分类成功率没有显著影响。建议对这种非常简短的筛查工具的良好特性进行交叉验证。
