This paper presents a new approach to preventing adolescent pregnancy. Information alone is not sufficient to prevent teenage pregnancy. The teenagers ability to choose and remain committed to a decision also needs to be developed. Because decision making skills are best learned through practice in an environment with frequent feedback, we have developed a computer game which simulates the consequences of different sexual roles. In addition, the game is intended to increase communication about sex between teenagers and their role models (peers, teachers and/or parents). Increased communication is expected to reduce the feeling of guilt and lead to either consistent abstention from sex or consistent contraceptive use. The paper reports on the development of the computer game and the preliminary evaluation of its impact.
