This brief summarizes key findings from a random assignment impact study of Steps to Success, a home visiting program in San Antonio, Texas, designed to reduce rapid repeat pregnancy among young mothers. A small but growing body of evidence suggests a combination of individualized support services and improved access to effective contraception can promote healthy birth spacing among adolescent mothers. To build on this promising research, the Administration for Children and Families partnered with Mathematica to conduct an evaluation of Steps to Success. Healthy Families San Angelo (HFSA) developed this intervention by enhancing its traditional home visiting program, which focused on child development and parenting, to include additional components designed to (1) promote healthy birth spacing, with an emphasis on increasing the use of long-acting reversible contraceptives (LARCs); (2) encourage father involvement; and (3) support mothers’ education and career aspirations.
