This study included participants from the following locations:
- California
Study Participants
Participants were recruited via referrals to a county public health department and assigned randomly to either the intervention or the comparison group. Initially 144 mothers were randomly assigned, 75 to the treatment group and 69 to the comparison group (information obtained from authors). One hundred twenty-one young mothers and their children participated in the study. Sixty-two were assigned to the intervention group, and 59 were assigned to the comparison group. At the one-year follow-up 102 adolescent mothers participated in the study, 55 in the intervention group and 47 in the comparison group. Most were poor, unmarried, and expecting their first child. Mothers ranged in age from 14 to 19 years old at intake (26 weeks or less gestation). Sixty-four percent of the mothers were Latina, 11 percent were African American, and 19 percent were white. Participants were followed from pregnancy through six weeks postpartum. Note: This study contains the same sample as Koniak-Griffin et al. (1999, 2000).
Setting
The study was conducted in San Bernardino County, California, a large, ethnically diverse county adjacent to Los Angeles.
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
Comparison group members received traditional public health nursing services, consisting of three home visits: one at intake, one for prenatal care, and one for postpartum/well-baby care information.
