Policy capturing was used to assess the relative influence of one's own att
itudes and those of a sexual partner on decisions about condoms. Participan
ts read vignettes describing a romantic encounter between themselves and a
hypothetical date. Each vignette contained six independent variables; three
described aspects of the participant's attitudes toward condoms, and three
described the corresponding attitudes of the date. For each scenario, part
icipants judged the likelihood that they would use a condom should they hav
e intercourse. The decision was independently affected by the attitudes of
both participant and date. A second experiment showed the date's influence
increasing with time constraints. The results suggest that efforts to incre
ase condom use may require heightened awareness of the influence of the oth
er's attitude on decision-making.
