Judgmental Heuristics: Implications for the Decision Making of School Psychologists

pp. 322—330

ABSTRACT: The Learning Accomplishment Profile-Diagnostic Edition and the Vineland Adaptive Behavior Scales were subjected to a multi-trait-multi-method (MTMM)analysis with a sample of 40 randomly selected preschool children. The Stanford-Binet was used as a criterion measure. The comparisons did not offer support for the convergent validity of like-named scales. Both within- and between-scale correlations indicate potential difficulties for profile interpretations of adaptive and developmental functioning. Item comparison ratings revealed that different facets of skills within the same domains are being measured. The practical difficulties associated with test usage for preschool children are discussed.
