Test Scatter on the WISC-R in Learning Disabled Children.
Tabachnick, Barbara Gerson
Scatter on the revised Wechsler Intelligence Scale for children (WISC-R) was evaluated for 105 learning disabled (LD) children. Scatter was defined as range of scaled scores on: (1) five regular verbal tests; (2) five regular performance tests; and (3) all 10 regular subtests. Pairwise combinations of 11 subtests were also evaluated for deviations in scaled scores. A discrepancy of 3 or more points was defined as significant deviation. A significantly greater range of scaled scores over the 10 subtests was found for the LD sample as compared with the 1976 standardization sample for the WISC-R. On the separate major scales, LD children on the average showed greater range over performance, but not verbal scales. Pair deviations for LD children were generally similar to those of normative children Most notably, all pairs including coding showed greater deviation for LD children. Among LD children, differences in test scatter were associated with age, but not IQ or sex. LD children under 11 years showed a greater range of verbal scale scores than older LD children. All statistically significant differences were of small magnitude, so that test scatter, by itself, would not be recommended as a major diagnostic sign. (Author/GDC)
