Abstract
Evidence from studies of ethnic differences in sexual conservativeness and Papanicolaou (Pap) testing behaviors suggests that there may be culture-linked differences in rates of participation in physically invasive sexuality studies, resulting in volunteer bias. The effects of ethnicity and acculturation on participation in female psychophysiological sexual arousal research were investigated in a sample of Euro-Canadian (n = 50) and East Asian (n = 58) women. Participants completed a battery of questionnaires and were given either course credits or $10 for their participation. Participants were then informed about the opportunity to participate in a second phase of the study, which involved psychophysiological sexual arousal testing and which was completely optional. Contrary to expectations, the results showed that the East Asian women were more likely to participate in Phase 2 than the Euro-Canadian women. Among the East Asian women, greater heritage acculturation and lower mainstream acculturation predicted a lower likelihood of Phase 2 participation. The findings suggest the need to be wary of overgeneralizing female psychophysiological sexual arousal research results and may have implications for improving Pap testing behaviors in East Asian women.
