Single-component models

Single-component models approach intervention by targeting specific areas known to impact child development. Interventions to be discussed include research designs that focus on modifying areas of nutrition, health, or education. Nutritional interventions typically support dietary change by providing deficient nutrients or supplementary feeding. Medical interventions have focused on increasing access to primary, preventive child care, and educational interventions have emphasized an early awareness of skills important for successful school achievement. The population targeted for these interventions includes children at risk for adverse developmental outcomes. Outcome measures primarily focus on cognitive and physical domains of child development.
