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. 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 20 percent were white. Participants were followed from pregnancy through year six weeks postpartum. Note: This study contains the same samples as postpartum. Note: This study contains the same samples as is a follow-up to Koniak-Griffin et al. (1999). |

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. |

External social competence |
Socialcompetence measureswerecomposites derivedfrom (1)the Rosenberg Self–Esteem Inventory,(2)Pearlin’sSenseofMastery Scale, (3)the Centerfor EpidemiologicalStudies DepressionScale,(4) thePerceived StressScale;(5)the Community Life SkillsScale(CLSS), and (6)the SocialSkills Inventory (SSI). Factor analysis was used to develop two conceptual factors representing Internal and external social competence. Composite measures were formed by first standardizing each measure to a 0–100 scale with higher numbers representing higher skills, then averaging the relevant translated scores. | Parent/caregiver report | Not reported by author |
