This review examines the psychologically oriented literature on adolescent contraceptive use. Descriptive studies, individual difference studies, and theory-based studies from family planning, medical, and applied journals are covered, as well as studies appearing in psychology journals. The research covered suggests that adolescents are largely uninformed about reproductive physiology and about many methods of contraception.

(Comfort & Comfort, 1979, p. 70) Attitudes toward adolescent sexuality have changed greatly during the past three decades. There have been even more dramatic changes in contraceptive technology during the same period, including the introduction of oral contraceptives, intrauterine devices (ILTDs), and, most recently, the contraceptive sponge. Despite these changes, adolescent pregnancy rates continue to rise. In 1978, 1.14 million American teenagers-over 10% of all teenage women-became pregnant. The large majority of these pregnancies were unplanned and unwanted. Over 80% were conceived premaritally, and almost 40% ended in abortion (Alan Guttmacher Institute, 1981). In 1979, one
