To date, only one study has looked at program intensity at the level of the individual child: the Infant Health and Development Program. As indicated in the discussion of low birthweight in Chapter 3, the amount of intervention each child and family received, monitored daily over the first three years of life, had a strong, positive effect on the child’s intellectual and social development at 36 months. Blair et al. (1995) found that children’s yearly intellectual development was strongly linked to variations in yearly participation rates.
