Susceptibility of elderly Asian immigrants to persuasion with respect to participation in research.

Familism, respect for authority, and a sense of shame/pride are cultural characteristics that might influence research participation of Asian Americans. We compared 79 elderly Asian immigrants, most of whom immigrated from China or Hong Kong, with 58 elders who were not Asian and mostly not immigrants. Responding to hypothetical situations presented on a self-administered questionnaire, the Asian group professed to be more likely to be influenced by a request from a son/daughter, landlord, physician, or advertisement (p<0.001) and by a monetary incentive (p=0.05). Multivariate adjustment for potential confounders attenuated the strength of these relations, but except in the case of the monetary offer, differences remained statistically significant. Within the Asian group, multivariate logistic regression modeling indicated that years lived in the US was associated with more likelihood of refusing requests to participate in research. We conclude that acculturation or assimilation into American society may build resistance to pressure to participate in research. Our findings also suggest that elderly Asian immigrants may need additional protections to achieve truly informed consent.
