Purpose-To encourage dual contraceptive method use --protection from both STD and pregnancy --health behavior change efforts must target powerful risk and protective factors that are amenable to change. This study examines longitudinal relationships between adolescents' contraceptive-related cognitions and dual method use.Methods-Data are from 1,123 sexually active 7-11 th grade participants in the National Longitudinal Study of Adolescent Health, Waves 1 and 2 (W1, W2). A series of nested path models examined relationships between participants' contraceptive use level at most recent intercourse (zero, one, two methods) and contraceptive-related cognitions. Parallel analyses were completed with four grade/gender groups.Results-Dual method use at most recent intercourse ranged from 14.3% to 25.0%. Path models suggested that contraceptive use patterns and contraceptive-related cognitions were moderately stable over time. Cross-sectionally, contraceptive use level was associated with parent approval of birth control (older youth, younger girls), birth control attitudes (older youth, younger boys), perceived pregnancy consequences (older youth), perceived STD risk (older girls), perceived benefits of sex (younger girls), and contraceptive self-efficacy (older youth). W1 father approval of birth control (younger girls), mother disapproval of sex (older girls), and birth control attitudes (older boys) predicted W2 contraceptive use levels. W1 contraceptive use levels predicted several W2 cognitions among older youth.Conclusions-Sexually active adolescents' perceptions of parent expectations about sex and contraception have important links to dual method use. Adolescents' attitudes about practical, social and moral implications of using birth control are also linked to their use of dual contraceptive methods.
KeywordsAdolescents; Dual method use; Contraceptive attitudes and beliefs; Path models There is growing interest in promoting dual method contraceptive use as a means of preventing both pregnancy and sexually transmitted diseases (STD). This goal is particularly worthy among sexually active adolescents, a group that experiences relatively high pregnancy and STD rates. While pregnancy rates among 15-19 year olds showed sustained declines during the 1990s, current rates remain among the highest in the industrialized world [1,2]. U.S. . Even with these increases, the proportion of adolescents using dual protection lags behind the proportion of youth at risk for pregnancy and STD.To be more effective in promoting dual method use among sexually active adolescents, we must understand antecedents of dual method use. To impact dual method use, our health behavior change efforts must target risk and protective factors determined to be most powerful and amenable to change through intervention. While clinic and community-based interventions are not well suited to address overarching socio-cultural antecedents of unprotected intercourse (e.g., poverty), these efforts can effectively shape attitudes, beliefs and skills...
