Notes:

Information on how certain measures were constructed and their reliability, information to satisfy the baseline equivalence requirement for findings with high attrition, and information on the regression imputation method were based on correspondence with the author. HomVEE's calculations for statistical significance are used because authors' calculations were based on one-tailed statistical tests. Several findings not reported in the tables below received a low rating because they had high attrition and did not satisfy the baseline requirement or failed to establish face validity and/or did not satisfy the reliability requirement. Findings about mothers’ civic engagement, partnership status, marital status, household size, the presence of grandparents, 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. Measures of the fathers’ income and employment status are ineligible for review because HomVEE does not review measures of family self-sufficiency for the father, unless the manuscript clearly indicates that the father resides in the household.

Several findings for the Ages and Stages Questionnaire, and for subscales of the MacArthur-Bates Communicative Development Inventories, Brief Child-Toddler Social and Emotional Assessment, Developmental Profile-3, and Adult Adolescent Parenting Inventory 2, as well as findings about child's health and health problems, are duplicates of those reported in two peer-reviewed manuscripts: Doyle et. al (2015) and Doyle et. al (2017). These findings are reported under those peer-reviewed manuscripts.

Study characteristics
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 (“low PFL”; 118 participants) that did not receive home visiting services. The study included a total of 165 participants, 82 in the high PFL group and 83 in the low PFL comparison group. Outcomes were measured when the children in the sample were 12 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.
Subgroups examined This field lists subgroups examined in the manuscript (even if they were not replicated in other samples and not reported on the summary page for this model’s report).

• 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)

Funding sources The Atlantic Philanthropies and the Department of Children and Youth Affairs (Ireland) supported the research.
Author affiliation Dr. Doyle and the Preparing for Life Evaluation team are affiliated with the University College Dublin Geary Institute for Public Policy. The authors were contracted by the home visiting model developers to evaluate Preparing for Life—Home Visiting.
