基于计划行为理论的医师处方基本药物行为实证研究

Empirical Study on the Behavior of Physicians Prescribing Essential Medicine Based on the Theory of Planned Behavior

目的:探讨影响医师处方基本药物行为的主要因素,促进我国基本药物可及性的进一步提高。方法:运用计划行为理论梳理医师处方基本药物的决策路径,建立医师处方基本药物行为的结构方程模型,从行为态度、主观规范、知觉行为控制三方面剖析医师处方行为的影响因素。结果与结论:行为态度对医师处方基本药物的意向有所影响但并不强烈,主观规范、知觉行为控制与其行为意向有较显著的正向关系;而医师的行为意向直接影响着其对基本药物的处方行为,知觉行为控制则对医师处方基本药物行为没有直接的影响,只通过行为意向产生间接的影响。
