Table 4.
Discrepancies between mean IQ and adaptive behavior domain scores and composite scores.
| Domain/composite | Standard score (M = 100) | Discrepancy |
|---|---|---|
| VABS-II | ||
| Communication | 88.38 | 15.77* |
| Socialization | 76.12 | 28.03* |
| Daily Living Skills | 91.44 | 12.71* |
| Adaptive Behavior Composite | 83.52 | 20.63* |
| BASC-2 | ||
| Adaptive Skills Composite | 77.26† | 26.89* |
| ABAS-II | ||
| Conceptual | 81.26 | 22.89* |
| Social | 72.08 | 32.07* |
| Practical | 77.56 | 26.59* |
| General Adaptive Composite | 73.64 | 30.51* |
†The composite for the BASC-2 was the converted score used to create the common metric for the cross-measure comparisons (Table 3). Discrepancies were based on the difference between the group's IQ M = 104.15 and the domain/composite score from the adaptive measures.
