The factorial structure of the CST14 was analysed and its relationship with several tests of cognitive function examined. Participants were 106 consecutive attendants of a psychogeriatric day care centre (75 women, 31 men). Their mean age was 77.7 (SD = 6.4). Factor analysis of CST14-scores revealed four principal components accounting for 66% of the explanatory variance. The factors reflected knowledge of current and last queen, orientation to date, day, age and time of day, date of birth, and home address. A stepwise regression model including measures of episodic recall, episodic recognition, confrontation naming and category fluency explained 55% of the variance in CST-scores. No explanatory variance was left for measures of visual and visuospatial perception (thematic apperception and clock reading). Dissociations between items of the CST may reveal individual profiles of impaired and relatively intact cognitive functions, such as preserved episodic memory (orientation to date) in aphasic patients.
对CST14的因子结构进行了分析，并研究了其与多项认知功能测试的关系。参与者是一家老年精神病日间护理中心的106名连续就诊者（75名女性，31名男性）。他们的平均年龄为77.7岁（标准差=6.4）。对CST14得分进行因子分析，发现四个主要成分，占解释方差的66%。这些因子反映了现任和上一任女王的知识、日期、星期、年龄和一天中的时间定向、出生日期和家庭住址。一个逐步回归模型，包括情景回忆、情景识别、对名命名和类别流畅性的测量，解释了CST得分方差的55%。视觉和视觉空间感知测量（主题统觉和时钟阅读）没有剩余的解释方差。CST项目之间的分离可能揭示受损和相对完整认知功能的个体特征，例如失语症患者中保留的情景记忆（日期定向）。
