The model developers enhanced the program by pairing CAMI with home-visiting services called CAMI+. In addition to the standard program, CAMI+ provided participants with biweekly or monthly home-based parent training and case management services to help the participants address issues related to housing or child care, for example. The 16-module curriculum, designed specifically for African American adolescent mothers, drew on social cognitive theory and covered topics such as child development and discipline. The home visits were initiated prenatally at about 32 weeks gestation. Each CAMI+ counselor served a maximal caseload of 25 participants visited monthly .
