Andersen’s behavioral model was the primary conceptual model for studying patient’s behavior on health care utilization. After dozens of revision, initial model structure of “predisposing, enabling, need” was changed to the structure of “environment, population characteristic, health behavior, health outcome”. Through review on the theoretical literatures and case studies on Andersen’s behavioral model, this paper revealed model development on structure, variables, and interaction between variables. The developed model will be not only helpful for studying on health care utilization by general population, but also helpful for the nursing care and self-medication by subpopulation such as, the chronic patients, the aged, the pregnant and so on. Using methods of path analysis and structural equation model, Andersen’s behavioral model could provide theoretical and practical perspective on health care utilization by corresponding subpopulation.
