This research was designed to identify determinants of unintended preg
nancy among women attending family practice or family planning clinics
. Survey data were collected from 95 women who were categorized accord
ing to whether or not they had experienced an unintended pregnancy. Wo
men reporting unintended pregnancy were younger, reported earlier sexu
al debut and a greater number of sexual partners than those not having
experienced an unintended pregnancy. Those who had avoided unintended
pregnancy displayed higher levels of preventive sexual self-efficacy,
had more confidence in their ability to use contraceptive methods, pe
rceived more negative consequences associated with having children in
the near future, and believed pregnancy among unmarried women to be le
ss acceptable than did women who had had unintended pregnancies.
