Abstract | Principal components analysis of standardization sample data for the Comprehensive Test of Adaptive Behavior, involving 6,647 persons with mental retardation, found that a single factor accounted for 86 percent of the variance in category scores. Use of the Total Score and idiographic item clusters is psychometrically preferable to use of category scores. (Author/JDD) |
