During 1998 and 1999, researchers at Rutgers, the State University (New Jersey) completed and partially disseminated the results of the Early Intervention Systems Study (EISS), a longitudinal study of early intervention for young children with developmental disabilities and chronic medical conditions.
The researchers reported the following findings to RWJF:
- The majority of children (62%) had at least one medical condition at the time of entry into early intervention, and of those, 40 percent had multiple diagnoses.
- Children without a medical condition who received early intervention services were most likely to have been referred because of developmental delay in communication skills.
- Families of children with medical conditions tended to have lower incomes and education levels than families of children without a medical condition.
- A medical condition significantly increased the cost of caring for a child.
- Slightly more than half (51%) of mothers in the study sample were full-time homemakers.
