The delivery to impoverished mothers of a coordinated set of medical and social services, including day-care for their children, had effects that were evident a decade after the intervention ended. Intervention mothers were more likely to be self-supporting, and they had higher educational attainment and smaller family sizes than did control mothers. Intervention children had better school attendance, and boys were less likely to require costly special school services than were corresponding control children. The financial implications of these results were considerable, totaling about $40,000 in extra estimated welfare costs and documented school service costs needed by the 15 control families in the single year in which these follow-up data were gathered. There were no indications that the intervention had lasting effects on the children's IQ scores. The results suggest that family support procedures, including quality day-care, have considerable promise as a general model for intervention programs.
