Missouri Children's Behavior Checklist profiles with developmentally disabled children: construct validity.

The clinical utility and construct validity of seven new MCBC behavior profiles were evaluated and compared to the original four behavior profiles. The relationship between the seven new behavior profiles and the clinical findings and recommendations that stem from an interdisciplinary evaluation of children referred to a clinic for development disabilities was determined. The seven cluster solution classified equally as well as the four cluster solution, but with increased differentiation into more specific internalizing and externalizing behavior profile subgroups. Construct validity information was provided for several of the new profiles in terms of the association with clinical findings of behavior problems and recommendations for therapy.
