Information on how certain measures were constructed and their reliability and on sample sizes for each finding were based on correspondence with the author. Findings reported when children in the sample were 36 months old are ineligible for review because high PFL families were offered Triple P, a parenting course promoting healthy parenting practices and positive parent-child attachment, when children were between 24 and 36 months old, and the low PFL group was not offered these services. Several findings not reported in the tables below, including all findings at 18 months, received a low or indeterminate rating because they had high attrition and did not satisfy the baseline equivalence requirement or did not satisfy the reliability requirement.
| Study participants | Study participants were pregnant women recruited in a maternity hospital or in the community. A total of 233 pregnant women were randomly assigned to either the Preparing for Life—Home Visiting group that received home visiting services (“high PFL”; 115 participants) or the comparison condition that did not receive home visiting services (“low PFL”; 118 participants). The study included a total of 170 participants, 81 in the high PFL group and 89 in the low PFL comparison group. Outcomes were measured when the children in the sample were six, 18, and 36 months old. At intake, the average age of the mothers was 25. The percentage of mothers identifying as Irish was 96 percent, and 4 percent identified as Irish Traveller. About half of the women were first-time mothers. |
|---|---|
| Setting | The study took place in North Dublin, Ireland. |
| Intervention services | Preparing for Life—Home Visiting provided home visits that lasted 30 minutes to two hours during the mother’s pregnancy and until the child started school at age 5. The majority of participants received visits every two weeks, though some participants received services monthly. The home visitor was a trained Preparing for Life mentor. The mentor provided information by using tip sheets and worked with participants to resolve issues around the child’s development, including the child’s prebirth development, nutrition, rest and routine, and cognitive and social development. The mentor also addressed the mother and her supports. Participants had access to baby massage sessions until the child was 10 months old. Participants also received packages of materials, including home safety items (corner guards, angle latches, heat-sensitive spoons, and baby gym/play mats) and toys (puzzles, activity toys, and bricks), worth about 100 Euros per package. |
| Comparison conditions | Participants in the low PFL (comparison) group did not have access to the home visiting services or tip sheets. The comparison group did, however, receive some of the same resources made available to the high PFL (intervention) group, including the package of safety items and toys. These participants had access to an information officer who met with participants before the child’s birth and at various intervals after birth and provided information on Preparing for Life community events and other local services. Participants in the comparison group had access to public health workshops, such as a stress-control program and a healthy food program. |
