Study Characteristics
Study Participants	American Indian adolescent females ages 12 to 19 years at conception and at 32 weeks or earlier gestation who resided in one of four participating communities were recruited. The study sample included 322 participants who were randomly assigned to either the Family Spirit group (159) or the control group (163). The average age of participants at baseline was 18.1 years. Sixty percent lived with their parents and slightly more than half lived in two or more homes within the past year. Seventy-seven percent of participants were pregnant with their first child. During pregnancy, 14 percent of participants drank alcohol, 19 percent smoked cigarettes, and 13 percent used marijuana.
Setting	The program was implemented in four tribal communities across three reservations in Arizona.
Intervention Services	Family Spirit is a home visiting program for young American Indian pregnant and parenting mothers staffed by American Indian paraprofessionals. The program’s goals are to increase mothers’ parenting knowledge and involvement, mothers’ psychosocial functioning, and children’s emotional and behavioral outcomes. The curriculum includes 43 lessons that cover parenting skills, infant development, and maternal psychosocial development. The frequency of the visits depends upon the stage of the program. One-hour home visits are provided weekly during pregnancy, biweekly visits for the first four months following the child’s birth, monthly from 4 to 14 months postpartum, and then bimonthly until the child’s third birthday. The study did not specify the dosage of services that program participants actually received.
Comparison Conditions	Participants in the control group received transportation to and from prenatal and well-baby visits, information on child care and community resources, and referrals for services.
Staff Characteristics and Training	Home visitors were trained for more than 80 hours on the evaluation protocol and delivering the intervention. After training, home visitors were required to demonstrate 85 percent mastery or better of the Family Spirit curriculum. Quarterly supervision visits and review of an audio recording of 20 percent of visits were administered to examine whether home visitors adhered to the intervention protocol
Funding Sources	Support for this research was provided by the National Institute on Drug Abuse.
