The aim of the presented research was to obtain the initial data regarding the validity of Montreal Cognitive Assessment (MoCA) in diagnosing cognitive impairment in psychiatrically hospitalized patients.
The results in MoCA obtained from 221 patients were analyzed in terms of proportional participation of patients with particular diagnosis in three result ranges. In 67 patients, additional version of the scale was also used. Comparative analysis of average results in particular diagnostic groups (organically based disorders, disorders due to psychoactive substance use, psychotic disorders, neurotic disorders and personality disorders) was also carried out, as well as an analysis of the scale's accuracy as a diagnostic test in detecting organic disorders.
The reliability of the test measured with between tests correlation coefficient rho=0.92 (P=.000). Significant differences between particular diagnoses groups were detected (J-T=13736; P=.000). The cutoff points of 23 turned out to have a satisfactory sensitivity and specificity (0.82 and 0.70, respectively) in diagnosing organically based disorders. The area below the receiver operating characteristic curve (AUC=0.854; P=.000) suggests that MoCA has a satisfactory value as a classifier.
The initial data suggest MoCA's high value in prediction of future diagnosis of organically based disorders. The initial results obtained in particular group of diagnoses support construct validity of the method.
本研究旨在获得蒙特利尔认知评估（MoCA）在诊断住院精神病患者认知障碍方面的有效性的初步数据。
分析了 221 名患者的 MoCA 结果，根据特定诊断患者在三个结果范围内的比例参与情况进行分析。在 67 名患者中，还使用了该量表的附加版本。还对特定诊断组（基于器质性障碍、精神活性物质使用障碍、精神病性障碍、神经症性障碍和人格障碍）的平均结果进行了比较分析，以及对该量表作为诊断检测检测器质性障碍的准确性进行了分析。
用测试间相关系数 rho=0.92（P=.000）测量测试的可靠性。在特定诊断组之间检测到显著差异（J-T=13736；P=.000）。23 的截止值在诊断器质性障碍方面具有令人满意的灵敏度和特异性（分别为 0.82 和 0.70）。接收者操作特征曲线下的面积（AUC=0.854；P=.000）表明 MoCA 作为分类器具有令人满意的价值。
初步数据表明 MoCA 在预测未来器质性障碍诊断方面具有很高的价值。在特定诊断组中获得的初步结果支持该方法的结构有效性。
