Study characteristics
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. In the analysis, however, one mother in the comparison group was analyzed as part of the intervention group, resulting in an analytic sample of 63 in the intervention group and 58 in the comparison group (information obtained from authors). Most were poor, unmarried, and expecting their first child. Mothers ranged in age from 14 to 19 years old. Sixty-four percent of the mothers were Latina, 11 percent were African American, and 20 percent were white. Participants were followed from pregnancy through six weeks postpartum. Note: This study contains the same sample as Koniak-Griffin et al. (2000).
Setting The study was conducted in San Bernardino County, California, a large, ethnically diverse county adjacent to Los Angeles.
Intervention services The intervention included a combination of home visits and motherhood preparation classes, both conducted by specially trained public health nurses. The intervention began in mid-pregnancy and continued through the first year of the infant’s life. Participants received approximately 17 home visits by a public health nurse. Each visit lasted between two and two and a half hours. In addition, participants attended four “Preparation for Motherhood” classes lasting six hours each. In addition, The intervention covered five main content areas: (1) health, (2) sexuality and family planning, (3) life skills, (4) maternal role, and (5) social support systems.
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.
Staff characteristics and training The public health nurses in this study had a minimum education level of a bachelor’s degree in nursing. They received special training and used written protocols as guides in implementing the intervention and the traditional public health nursing services.
