Intellectual and adaptive functioning: some tables for interpreting the Vineland in combination with intelligence tests.

A set of tables was provided with the differences necessary for statistical significance between the Vineland Adaptive Behavior Scales and the Bayley Scales of Infant Development. McCarthy Scales of Children's Abilities, Stanford-Binet Intelligence Scale (4th ed.), and all current Wechsler intelligence scales. This information may be beneficial in determining whether discrepancies in the Vineland and measures of intelligence can be attributed to chance alone or whether they represent real differences. In light of normative sampling diversity, regression effects, and procedural factors, which result in varying and indeterminate error in the tables, the tables can only augment clinical decision, not replace it.
