| Study participants | This study relies on data from a randomized controlled trial of 17 Early Head Start (EHS) programs that began in 1995, and focuses specifically on the outcomes of families in one of the 17 programs, located in Utah. This program served clients through a home-based option (EHS-HBO). The study randomly assigned 201 families either to receive EHS-HBO or a comparison condition. For this group, attachment security data were available for 160 children (83 in EHS-HBO and 77 in the comparison group). Among the parents of these children, 22 percent were racial or ethnic minorities, 20 percent had less than a high school education, 22 percent were employed, and 27 percent were receiving public assistance. |
|---|---|
| Setting | Bear River Early Head Start–Home-Based Option provided services to families in three rural counties in northern Utah and southern Idaho. |
| Intervention services | EHS-HBO services are intended to be delivered to study families via weekly home visits. |
| Comparison conditions | Control group families could not receive EHS-HBO services, but could receive other services available in their community. |
