Children of Poverty: A Multi-Level Analysis of the Determinants of Intellectual Development.
Lee, Marvin; Burchinal, Margaret
Within a longitudinal design, the present study assessed parental attitudes, quality of stimulation in the environment, historical factors, and children's temperament to identify determinants of cognitive ability at 54 months. Children (n=147) were randomly assigned to one of three treatment groups: a center-based intervention, a home-based intervention, or a control group. Maternal IQ and an index of biological risk at birth were measured. Parental attitudes, quality of the home environment, the number of months in day care, and children's temperament were assessed at regular intervals during the preschool years. The analysis strategy was to select the best regression model from the data of the control sample. The model (composed of measures of center day care attendance, an environmental stimulation factor, task orientation, maternal IQ, and a biological risk index) explained 35% of the observed variance in IQ scores of control group children at 54 months of age. Quality of the home and task orientation as measured during infancy made significant independent contributions to this model. This model was then tested with the two other groups, significantly predicting IQ of children in both the home-based and center-based groups at 54 months of age. The environmental stimulation factor demonstrated a significant linear association with IQ in all three groups. Results of this study demonstrate that a multi-level model of the determinants of cognitive performance at 54 months can be successfully constructed and validated, and underline the relationship between environmental stimulation and children's IQ.
