The author performed a study among U.S. undergraduates to test an earlier c
onclusion (D. Trafimow, 1994) that confidence in the correctness of one's p
erceptions of normative pressure to use a condom influences the corresponde
nce between those perceptions and the intentions actually to perform the be
havior. Consistent with previous findings (Trafimow), the participants' per
ceptions of normative pressure strongly predicted their intentions to use c
ondoms only under conditions of extreme normative confidence. Otherwise, th
eir attitudes were better predictors of their intentions to use condoms. In
addition, 2 other variables (attitudinal confidence and perceived behavior
al control) were found to be unimportant predictors of intentions. Results
of a 2nd study suggest that behaviors performed by sexual partners and know
ing the sexual partners affected the participants' normative confidence.
