In the interim, test users should employ screening tests which are more accurate such as the Minnesota Inventories or the Battelle Developmental Inventory Screening Test. The findings suggest that the authors of the Denver-II need to engage in further development of the instrument including revising scoring criteria and item placement in relation to children's ages. Only items in the language domain were modestly helpful in discriminating children with and without difficulties. Since neither scoring method produced acceptable levels of accuracy, an effort was made to locate the sources of accuracy and inaccuracy within the test. The alternative scoring method, categorizing questionable/untestable scores as normal, caused sensitivity to drop to 56% although specificity rose to 80%. Thus the test had limited specificity (43%) and a high overreferral rate. However, more than half the children with normal development also received abnormal, questionable, or untestable Denver-II scores. The Denver-II identified correctly 83% and thus had high rates of sensitivity. Developmental problems including language impairments, learning disabilities, mild mental retardation, and/or functional developmental delay were found in 17% of the children. A second psychological examiner, blind to the outcome of the diagnostic battery, administered the Denver-II.

To determine the presence of developmental problems, children were administered individual measures of intelligence, speech-language, achievement, and adaptive behavior. Because it was published without evidence of its accuracy, the present study was undertaken with 104 children between 3 and 72 months of age attending one of five day-care centers.

One of the oldest and best known developmental screening tests was recently restandardized and revised as the Denver-II.
