Abstract

This study was designed to examine the validity of the Design Copying and Constructional Praxis subtests of the Sensory Integration and Praxis Tests (SIPT) (Ayres, 1989) through an examination of convergent validity and the use of contrast groups. The subjects were 39 children aged 5 to 8 years. Of these children, 21 had learning disabilities and 18, who served as the control group, had no learning disabilities. The subjects were administered the SIPT as well as four other standardized measures of constructional abilities: the Developmental Test of Visual-Motor Integration (Beery, 1980), the Block Design subtest of the Wechsler Intelligence Scale for Children–Revised (Wechsler, 1974), the Primary Visual Motor Test (Haworth, 1970), and the Rey-Osterrieth Complex Figure Test (Waber & Holmes, 1985). The results indicated that the children with learning disabilities performed significantly more poorly than did the control subjects on both the Design Copying and Constructional Praxis subtests. These two subtests showed moderately high correlations (.46 to .71) with the other tests of constructional abilities when both groups were combined. Correlations were mostly in the moderate range for the children with learning disabilities but were generally not significant for the control sample. The results are discussed in terms of task demands and subject variability.
