The authors sought to validate a new approach to motor subtyping in delirium based on data from a controlled comparison of items from three existing psychomotor schema combined into the Delirium Motoric Checklist. Principal components analysis of the Delirium Motoric Checklist identified two factors that correlated significantly with independently assessed motor agitation and retardation. Symptoms loading at >0.65 were extracted to form subtype criteria composed of four hyperactive items and seven hypoactive items which, when applied to the delirious population, suggested a cutoff of two items for subtypes. This new scale is derived from existing approaches but is more concise, focused on motor disturbances, and validated against nondelirious comparison subjects and independently rated motor disturbance.
作者试图基于对来自三个现有精神运动模式的项目进行对照比较的数据，来验证一种用于谵妄运动亚型分类的新方法，这些数据被整合到《谵妄运动检查表》中。对《谵妄运动检查表》进行主成分分析，确定了两个与独立评估的运动激越和迟缓显著相关的因素。提取负荷量>0.65的症状，以形成由四个多动项目和七个少动项目组成的亚型标准，将其应用于谵妄人群时，建议各亚型的临界值为两个项目。这个新量表源自现有方法，但更简洁，专注于运动障碍，并针对非谵妄对照受试者和独立评定的运动障碍进行了验证。
