In 2020, HomVEE updated this review in two ways. First, HomVEE moved the finding "child treated for injury in the past year" from the Child Health domain to the Reductions in Child Maltreatment domain because the review initially misclassified it. HomVEE places findings related to medical care for injury and ingestions in the Reductions in Child Maltreatment domain. Second, HomVEE moved the finding "child was covered by health insurance" from the Child Health domain to the Family Economic Self-Sufficiency domain because ACF determined that health insurance coverage belongs in that domain.
| Study participants | The sample presented here includes 667 mothers with children who were assessed at 1 and 2 years of age. Across three sites, families with a child up to 8 months of age were recruited for enrollment in the Parents as Teachers (PAT) program. At the time of enrollment, mothers had an average education level of just over 12 years. Most study participants were African American (58%) or white (29%). The majority of households enrolled had an annual income of less than $15,000 (60%). Twenty-nine percent of children in the sample had two married parents. |
|---|---|
| Setting | Three local PAT programs participated in the evaluation: the first was located in an Eastern Seaboard rural community, the second was located in a mid-size Southern city, and the third was located in a large Western city. |
| Intervention services | Families enrolled in PAT received monthly home visits and other program services for as long as they remained in the program, up to the child’s third birthday. Among those families enrolled in PAT , 44% participated and remained in the program through the child’s second birthday (68% at Site 1, 35% at Site 2, and 31% at Site 3). |
| Comparison conditions | The comparison families received only the services that were normally available in the community and that they sought of their own accord. In addition, they received age-appropriate toys at regular quarterly intervals, which were used as a means of tracking their locations. |
