Efficacy of part- and full-time early intervention.

The effectiveness of an early intervention program to remediate developmental delays in children age birth to 3 years was examined in part- and full-time groups (Study 1). Significant improvements on age-appropriate measures of developmental standing were observed for both groups, with the greatest gains observed for the full-time group. In Study 2, the stress of parents with developmentally delayed children was measured on the Parental Stress Inventory. Reductions in stress related to children's characteristics and dysfunctional parenting skills were observed on some subscales, supporting prior research which indicated extension of the outcomes of early intervention beyond the child was desirable.
