Every quarter, the adolescents completed the computer-based survey assessing their sexual relationships, contraceptive intentions and plans, and current pregnancy prevention practices and participated in a motivational interview with the CAMI counselor. Each CAMI session lasted about 1 hour and included the computer-based survey and the 20 to 30 minute motivational interview.
The intervention began within six weeks postpartum (range 1-6 weeks postpartum) and continued for two years.
