Background: Given the importance of ethnic culture in family caregiving and recent Chinese immigrant population growth, this study explored effects of multiple filial piety traits-filial expectation, self-rated filial performance, and filial discrepancy-on psychological well-being of Chinese immigrants who care for older parents (adult-child caregivers) in the United States. Methods: This study used cross-sectional data from 393 Chinese immigrant adult-child caregivers in the Greater Chicago area from the 2012-2014 Piety study.
