Identification and description of tardive dyskinesia have been hampered by the absence of systematic studies assessing the psychometric properties of existing instruments. The purpose of this study was to establish construct validation of one of these instruments, the Dyskinesia Identification System--Coldwater. Cross-sectional prevalence assessment data of 519 institutionalized mentally retarded persons were used. The 34 items of this instrument were subjected to exploratory factor analysis. A six-factor orthogonal solution was selected. Multiple regression analyses supported the established relationships of demographic variables, such as age and sex, with the tardive dyskinesia scores generated by the instrument.
由于缺乏评估现有工具心理测量特性的系统性研究，迟发性运动障碍的识别与描述工作受到了阻碍。本研究的目的是对其中一种工具——运动障碍识别系统冷水版（Dyskinesia Identification System--Coldwater）进行结构效度验证。研究使用了519名机构收容的智力障碍者的横断面患病率评估数据。对该工具的34个项目进行了探索性因素分析。选择了一个六因素正交解。多元回归分析支持了年龄和性别等人口统计学变量与该工具生成的迟发性运动障碍评分之间已确立的关系。
