A growing body of evidence indicates that for some children, early incidences of challenging behaviors are predictors of later difficulties. These incidences of challenging behaviors may predict mental health issues, social adjustment issues and/or increased challenging behaviors that will impede school success and impact transition to adult life (Lipsey & Derzon, 1998; Wagner, Cometo & Newman, 2003; Walker, Ramsey & Gresham, 2005). This study seeks to explore the relationship between two commonly used assessments in early childhood settings, the Battelle Developmental Inventory (BDI) (given by caregivers/teachers) (Newborg, 2005) and the Child Behavior Checklist (CBC) (given by both parents and caregivers/teachers) (Achenbach, 2000). Two significant correlations that linked the use of the BDI and the CBC were found. Further research is needed with larger sample sizes. (Contains 1 table.)
