This report addresses the problem of sexually active teenagers who either do not use contraception or use it inconsistently. Psychological and cognitive barriers to contraception use are briefly reviewed and the development of a cognitively oriented intervention designed to modify beliefs inimical to contraceptive use is discussed. The selection of the Health Belief Model (HBM), a value-expectancy approach to explaining and predicting preventive health behaviors, as a tool for the intervention is described and four strengths of the HBM are presented. A discussion of key HBM concepts is given along with a review of some of the contraceptive literature relevant to the HBM. The design of the adolescent contraceptive behavior intervention is described and a chart is included which illustrates the adaptation of the HBM to the intervention. A four-step process for learning responsible sexual behavior is presented and the use of lectures and small groups in the intervention is described. It is recommended that field tests be conducted using a control group and a larger experimental group in order to evaluate the effectiveness of this intervention. (NRB)
