来自四项研究的数据被用来评估26个IQCODE项目的心理测量学特性。这些项目进行了评估的项目总的相关性，重测信度，与当前的认知功能指标的相关性和与指标的发病前认知功能。这些数据被用来开发一个16项的简短表格。在一个新的样本中，使用痴呆/谵妄诊断作为有效性标准，对简短形式进行了交叉验证。它被发现表现得和长型一样好。
Data from four studies were used to assess the psychometric properties of the 26 IQCODE items. The items were assessed in terms of item-total correlations, test-retest reliabilities, correlations with indicators of current cognitive functioning and correlations with indicators of premorbid cognitive functioning. These data were used to develop a 16-item short form. The short form was cross-validated in a new sample using dementia/delirium diagnosis as the validity standard. It was found to perform as well as the long form.
