Notes from the review of this manuscript
In 2020, HomVEE updated this review to move the two findings on the number of child behavioral/parental coping problems in physician record from the Child Health domain to the Child Development and School Readiness domain because ACF determined that all measures of child behavioral health, including internalizing and externalizing behaviors belong in HomVEE's Child Development and School Readiness domain.
The Elmira sample included two deviations from the randomization procedure. First, six housemates of women already randomly assigned and enrolled in the study were assigned to the same treatment as the women already enrolled. Second, the probability of being assigned to one of the treatment groups was increased in the last 6 months of the 30 month enrollment period. The first issue suggests a mismatch between the unit of assignment (adult in the household) and the unit of analysis, which may lead to overstating the precision of the standard errors. The second issue should lead to a weighting strategy in the analysis, so that those who were enrolled later receive less weight in the analysis. Weighting, however, was not used in these studies.
The cases of abuse and neglect findings had high attrition and therefore rate moderate.

This study included participants from the following locations:
- New York
Study Participants
The sample included pregnant, first-time mothers who were less than 30 weeks pregnant. Women were recruited through health and human services agencies, including health clinics, Planned Parenthood, and public schools. In these locations, pregnant women who were less than 19 years old, were single parents, or had low socioeconomic status were actively recruited for the study. Between April 1978 and September 1980, 500 women were interviewed and 400 were randomly assigned. For this study, 46 nonwhite women were excluded from the sample. At enrollment, on average, the women were about 19 years old, 17 weeks pregnant, and had approximately 11 years of education. This study measured the sample at registration and at the 34th, 36th, 46th, and 48th months of the child’s life. For the data collection ant 48 months postpartum, the study sample included 343 women, 183 in the program group and 160 in the comparison group. (Information on sample size for this follow-up was received through communication with the author.)
Setting
The study was conducted in Elmira, a metropolitan area within a semi-rural county in the Appalachian region of New York that has approximately 100,000 residents.
Intervention condition
Note: Navigate to the model page for more information about the home visiting model. See the source manuscript for more information about how the model was implemented in this study.
Comparison Conditions
The study included two comparison groups, which were combined for the analyses. The first comparison group did not receive any services during pregnancy. When the children were 12 and 24 months old, they were screened for sensory and developmental problems and referred to other specialists, as appropriate. The second treatment group received free transportation (through a contract with a local taxi company) for prenatal and well-child care at local clinics and doctors’ offices. The second comparison group also received the 12- and 24-month developmental screening.
Subgroups examined
• Race/ethnicity (White) • Subgroups defined by combinations of maternal characteristics (White and uncomplicated pregnancy or unmarried and low-income teen)
