This study focused on 18- and 19-year old late adolescents, seeking to increase our understanding of the theoretical frameworks associated with adolescent sexual and contraceptive communicative behavior. Identity and self esteem were used to investigate these antecedents influence on adolescent communication, including communication self efficacy, comfort discussing sex and contraception, and perceived communication self efficacy regarding sex and contraception. This study offered a framework for understanding adolescent communication related to sex and contraception, illustrating that adolescents identity status does increase communication efficacy. However, the results did not confirm a relationship between identity status, and sex and contraceptive discussions.
