In this pilot study, we investigated the clinical use of the Miller Assessment for Preschoolers (MAP) (Miller, 1982) with a sample of children with suspected or confirmed developmental delays. A retrospective chart audit was performed for 95 subjects, 30 girls and 65 boys, 34 to 68 months of age. Clinically related diagnoses were classified into six medical/developmental groups and a no-diagnosis group. When an analysis of variance was used to compare the six medical/developmental groups with the no-diagnosis group, some of the MAP score patterns differed significantly (p < .01). These score patterns provide preliminary evidence for the MAP’s effectiveness in screening children with developmental delays.
