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). At the two-year follow-up, 101 adolescent mothers participated in the study, 56 in the intervention group and 45 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-two percent of the mothers were Latina, 13 percent were African American, and 18 percent were white. Participants were followed from pregnancy through two years postpartum. Note: This is a follow-up to Koniak-Griffin et al. (1999, 2000, 2002).
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.

In contrast to the study-reported results, HomVEE calculations showed this difference to be statistically significant (p = 0.05). The HomVEE tests of statistical significance are based on the HomVEE calculated effect sizes, whereas authors may have used other techniques, such as regression models or analyses of variance (ANOVA), to determine statistical significance.
