Abstract
Although young children in foster care are at high risk for developmental delays and subsequent academic, social, and behavioral difficulties, many do not receive services for delays. We sought to explicate the types of developmental delays observed in young children (ages 3-6 years) in foster care and how placement and maltreatment experiences for these children were associated with such delays. Physical growth, neuropsychological functioning, executive functioning, language, and general cognitive functioning were compared for a sample of 99 foster children and 54 nonmaltreated, same-aged children from comparable socioeconomic status backgrounds. The foster children showed developmental lags on measures of height, head circumference, visuospatial functioning, language, and general cognitive functioning. A history of neglect was negatively associated with functioning in a number of domains; surprisingly, the number of maltreatment types experienced was positively associated with functioning. Placement history was generally not associated with scores in the various developmental domains. We discuss the need to screen and evaluate preschoolers and possible methods for doing so.
