Correspondence analysis, a graphical tool for the presentation and interpretation of cross-classified data: An illustration using contraceptive behavior of male adolescents.

Expands on earlier studies on teenage sexual activity (SXA) and contraceptive use (CU) by M. Zelnik and J. Kantner (1980) and J. H. Pleck et al (see record [rid]1989-15205-001[/rid]) using the technique of correspondence analysis (CA). CA was used to elucidate the forms of the relationships among some of the earlier associations found among 624 never-married, sexually active men (aged 17–21 yrs) from the 1979 National Survey of Young Men. CA analysis showed that for Ss who did not use contraceptives at 1st intercourse, a higher level of completed or aspired education was related to a higher likelihood of CU at last intercourse. CA enabled a better understanding of the association between CU at last intercourse and relationship to last sexual partner: SXA with a friend is more likely to be unprotected, SXA with an engaged or steady partner to be protected by female CU, and SXA with a dating partner to be protected using condoms or withdrawal.
