Notes from the review of this manuscript
Information on sample sizes for this study was received through communication with the authors. HomVEE previously rated 24-month outcomes for nurse home visitors Moderate due to high attrition. Upon further examination, HomVEE noted that the outcomes had low attrition, and therefore they rate High.
This study received a mixed rating. All of the outcomes comparing paraprofessional-visited mothers versus the control condition for the main sample rate high. Outcomes for the low resources subgroup, for both the nurse-visited and paraprofessional-visited versus control comparisons, rate high. In addition, outcomes for the main sample for the nurse-visited versus control comparison at the 21-month follow-up rate high. Due to high attrition, the nurse-visited versus control comparison for the other follow-ups rate moderate.

This study included participants from the following locations:
- Colorado
Study Participants
Women were recruited through 21 antepartum clinics that served low-income pregnant women. Recruitment focused on women who had no previous live births and either qualified for Medicaid or had no private health insurance. From March 1994 through June 1995, 1,178 women were invited to participate and 735 consented and were randomly assigned to one of three conditions: a control group, nurse home visiting, and paraprofessional home visiting. Randomization was conducted within strata based on maternal race (Hispanic, white, black, American Indian, or Asian), maternal gestational age (less than 32 weeks, 32 weeks or more), and geographic region. This study measures the sample when the children were 6 months to 2 years old. The study sample at the 24-month parent interview included 630 women, 194 in the nurse home visiting program group, 213 in the paraprofessional home visiting program group, and 223 in the comparison group.
Setting
