Ecological factors predicting adolescent contraceptive use: implications for intervention.

Questionnaires addressing areas expected to relate to contraceptive use were completed by 230 female adolescents. Contraceptive use among the 130 sexually active subjects were predicted by a model composed of 12 scales assessing social permissiveness, costs and benefits of contraception, parent communication, boyfriend support, sex education and knowledge, attitudes about pregnancy and contraception, and access to contraception services. Scales from the predictive model which raise ideas for potential intervention strategies assessed parent communication, boyfriend support, and perceived costs and benefits related to contraception. Since there has been public concern that intervention programs for enhancing adolescent contraceptive use might also stimulate sexual activity, correlations were computed between the predictive scales and the measure of sexual experience among all 230 subjects. These data indicated that positive parent communication about sexuality and a perception of high benefits and low costs associated with contraceptive use were not positively correlated with sexual experience. Implications for the prevention of adolescent pregnancy are discussed with an emphasis on designing innovative sex education, improving parent-child communication, resolving conflicts in contraceptive decisionmaking, and supporting the role of boyfriends in contraceptive use.
