How Mexican American college students perceive responsibility for parental care is important as Mexican American elders' numbers increase. The authors applied mixed methods to investigate the impact of gender and biculturalism within this group. Two hundred and eighty-six Mexican American undergraduates completed the Hamon Filial Responsibility Scale. Twenty others participated in focus groups. Females endorsed filial responsibility expectations at higher rates than males, but biculturalism influenced more change in elder care expectations among males. (Contains 2 tables.)
