Abstract
Timely provision of early developmental intervention depends on accurate developmental screening tests. The Developmental Profile-II (DP-II) relies on parent report to assess children from birth to 7 years old. One of its subtests, the Academic scale, is designed for developmental screening. To test its accuracy in detecting children with problems, the scale was administered to parents of 94 children between 6 and 75 months old. Each child was also given a battery of tests, such as the Bayley Scales of Infant Development and the Stanford-Binet Intelligence Scale. The Academic scale detected only 21 % of the 19 children thus determined as having developmental problems, while 85% of the nondiagnosed children received normal or advanced scores on DP-II. Analysis revealed that DP-II scoring criteria are far too lenient and that many items are poorly placed in relation to age expectations. Alternative cutoff scores greatly improved sensitivity. DP-II is a potentially accurate measure that needs updating and restandardizing. Alternative tests include the Minnesota Child Development Inventory and the Battelle Developmental Inventory Screening Test.
