Construct validity of the Motivation Assessment Scale (MAS) (Durand, Crimmins, The Motivation Assessment Scale 1988) was studied using Rasch analysis data from 67 children (246 MASs), with dual diagnosis of autism and intellectual disability or with intellectual disability only. Results failed to support the proposed unidimensional construct or the original 4-factor structure. Some motivators appear to form a unidimensional construct: "to gain attention", "to gain a tangible object", and "to escape". There was evidence that sensory stimulation represents a different construct. Children with intellectual disability were more apt to be motivated by desire to gain a tangible item or attention. Children with the dual diagnoses were more apt to have sensory stimulation or escape from task demand as a motivator for stereotypic and repetitive behavior.
运用来自67名儿童（246份动机评估量表）的拉施分析数据，对动机评估量表（MAS）（杜兰德、克里明斯，《动机评估量表》，1988年）的结构效度进行了研究，这些儿童患有自闭症和智力残疾的双重诊断或仅患有智力残疾。结果未能支持所提出的单维结构或原始的四因素结构。一些动机似乎形成了一个单维结构：“获得关注”、“获得有形物品”和“逃避”。有证据表明，感官刺激代表了一种不同的结构。智力残疾儿童更倾向于受获得有形物品或关注的欲望所激励。患有双重诊断的儿童更倾向于将感官刺激或逃避任务要求作为刻板重复行为的动机。
