Elderly people from ethnic minority groups often experience different barriers in accessing health services. Earlier studies on access usually focused on types and frequency but failed to address the predictors of service barriers. This study examined access barriers to health services faced by older Chinese immigrants in Canada. Factor analysis results indicated that service barriers were related to administrative problems in delivery, cultural incompatibility, personal attitudes, and circumstantial challenges. Stepwise multiple regression showed that predictors of barriers include female gender, being single, being an immigrant from Hong Kong, shorter length of residency in Canada, less adequate financial status, not having someone to trust and confide in, stronger identification with Chinese health beliefs, and not self-identified as Canadian. Social work interventions should strengthen support and resources for the vulnerable groups identified in the findings. Service providers should adjust service delivery to better serve elderly immigrants who still maintain strong Chinese cultural values and beliefs.
