Notes
Child outcomes (Infant-Toddler Social Emotional Assessment) rated moderate for this study, because of high attrition. Through communication with the first author, we established that the mothers of children in the child outcomes sample were equivalent at baseline on race/ethnicity and SES; the child outcomes themselves were not assessable at baseline because the sample enrolled prenatally.
Study Participants

Between 2006 and 2008, expectant women who were at less than or equal to 32 weeks gestation, aged 12-19 at conception, self-identified as American-Indian, and residing in one of the four participating reservation communities, were recruited into the study. Eligible participants were randomized by site, age, and history of previous live births. The sample sizes for the maternal parenting and health outcomes were as follows: analytic sample: 322 (159 T and 163 C)baseline sample: 322 (159 T and 163 C). Note: the study does not use a consistent analytic sample across different outcomes. The sample sizes shown here are relevant for maternal outcomes only. Sample sizes for child outcomes differ.

Setting

Four southwestern reservation communities

Home Visiting Services

The Family Spirit intervention consisted of 43 lessons delivered by Native American para-professionals from within participating communities. The lessons focused on parenting skills and maternal behavioral and psychosocial risks. The lessons were conducted in each participant's home and the visits lasted approximately one hour each. The visits occurred weekly through pregnancy, biweekly until 4 months postpartum, monthly between 4-12 months postpartum, and bimonthly between 12-36 months postpartum.

Comparison Conditions

Optimized Standard Care consisted of transportation to recommended prenatal and well-baby clinic visits, pamphlets about childcare and community resources, and referrals to local services.
