All findings from the peer-reviewed journal article that is cited as an additional source were included in the review of the Early start evaluation report. Both manuscripts report an intersecting set of findings, while the Early start evaluation report contains additional findings not included in the peer-reviewed article. Several maternal outcomes describing employment, hardship factors, contraceptive use, and stressful life events received a low rating because they were assessable at baseline but were not assessed.
In 2020, HomVEE updated this review in three ways. First, HomVEE removed mother's partnership status/family structure findings from the Family Economic Self-Sufficiency domain because ACF determined that mother's partnership status is ineligible for review by HomVEE. Second, HomVEE removed the finding "percent parental report of agency contact for abuse/neglect" from the Reductions in Child Maltreatment domain because some cases measured may be unsubstantiated. In this domain, HomVEE reviews only outcomes focused on substantiated cases of abuse and neglect. Finally, HomVEE clarified that the direction for the finding on duration of attendance for early childhood education is ambiguous, rather than favorable.
| Study participants | Nurses screened all families in the Christchurch area who had new infants. Screening included an 11-point assessment of family stress and an evaluation of the client's need for Early Start services. A total of 588 families were determined to be eligible and 443 families agreed to participate. Those 443 families were then randomly assigned to either the treatment or comparison group. The analysis sample consisted of 184 families in the treatment group and 207 in the comparison group. Approximately one quarter of the analysis sample was Māori, and weekly income in both the Early Start and comparison groups averaged about $340 per week (according to information provided by the authors). Results are reported as of the 36-month follow-up (certain outcomes have fewer than 391 respondents at this follow-up). |
|---|---|
| Setting | The study was conducted in Christchurch, New Zealand. |
| Intervention services | Trained family support workers engaged in home visits to encourage positive family change in the following areas: child health, maternal well-being, parenting skills, family economic functioning, and crisis management. The services were tailored to each family’s particular circumstances. Initially, families received two hours of contact with a home visitor per week. Some families in crisis received more contact. The intensity of services decreased as families made progress. Once families became self-reliant, they received a home visit every three months. |
| Comparison conditions | Comparison participants were not offered any services beyond what is typically available to families in the Christchurch, NZ area. |
| Subgroups examined |
