This study examined a method for more precisely differentiating environmental influences from biological risk factors in children who had experienced early medical complications. Children in a longitudinal high-risk infant follow-up program were evaluated at age 5 to determine whether they demonstrated behavior problems or cognitive deficits exceeding expectations based on conditions in their home environments. Normal expectations were determined through regression analyses of the Home Environment Questionnaire on a group of age-matched controls. All high-risk children had been screened previously to exclude children with early developmental disabilities. Although many high-risk children were developing normally, substantial proportions showed significant behavioral and learning disabilities, even with adjustment for environmental conditions. These outcomes were not related in any simple fashion to medical risk factors, but complex statistical combinations of perinatal variables (through logistic regression) classified behavioral outcomes with a high degree of accuracy.
Key words: high risk; behavior; learning; environmental influences.
