Notes

Information on how certain measures were constructed and their reliability were based on correspondence with the author. Several findings not reported in the tables below received a low rating because they did not satisfy the reliability requirement. HomVEE’s calculations for statistical significance are used because authors’ calculations are based on one-tailed statistical tests. Findings about mothers’ civic engagement, partnership status, household size, child number of siblings, and whether the mother knows the baby’s weight are ineligible for review because they do not fall in one of HomVEE’s eligible outcome domains. Findings for child number of health problems for which they were taken to doctor/health center/casualty and child received medical attention for wheezing or asthma are duplicates of those reported in Doyle et al. (2015) and are reported under that peer-reviewed manuscript.

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 166 participants, 82 in the high PFL group and 84 in the low PFL comparison group. Outcomes were measured when the children in the sample were 24 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 condition
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.

Were any subgroups examined?
No
Subgroups examined

• Child gender (boy or girl) • Parity (primiparous) • Relationship status (single parent) • Cognitive resources of mother (high or low as measured by the Wechsler Abbreviated Scale of Intelligence) • Emotional well-being level of mother (high or low as measured by the World Health Organization Wellbeing Index) • Maternal substance use/disorder (smoked or drank during pregnancy) • Maternal familial risk (high as measured by a survey of household domestic risks)
