Explaining Immigrant Health Service Utilization: A Theoretical Framework

Although there is no paucity of theoretical frameworks for explaining people’s health service utilization (HSU), theoretical frameworks designed to account for variations in immigrants’ HSU remain underdeveloped. Building on influential theories or models for explaining HSU and especially Andersen’s widely used health behavior model, this article proposes a theoretical framework for explaining disparities in immigrant HSU. The proposed framework explains disparities in immigrant HSU by the health care need, resources, and predisposing factors of immigrants, and macrostructural/contextual conditions at both the general and immigrant-specific levels, as well as the mediating relationships among some of these factors. It is believed that this new framework can offer a fuller understanding of the determination process of immigrant HSU.
