The purpose of this article is to describe operationalization of the Theory of Planned Behavior (TPB). The quest to understand determinants of health behaviors has intensified as evidence accumulates concerning the impact of personal behavior on health. The majority of theory-based research has used the Health Belief Model(HBM). The HBM components have had limited success in explaining health-related behaviors. There are several advantages of the TPB over the HBM. TPB is an expansion of the Theory of Reasoned Action(TRA) with the addition of the construct, perceived behavioral control. The revised model has been shown to yield greater explanatory power than the original TRA for goal-directed behaviors. The process of TPB instrument development was described, using example form the study of smoking cessation behavior in military smokers. It was followed by a discussion of reliability and validity issues in operationalizing the TPB. The TPB is a useful model for understanding and predicting health-related behaviors when carefully operationalized. The model holds promise in the development of prescriptive nursing approaches.
本文旨在描述计划行为理论（TPB）的实施。随着有关个人行为对健康影响的证据不断积累，对理解健康行为决定因素的探索也日益加强。大多数基于理论的研究都采用了健康信念模型（HBM）。HBM的各个组成部分在解释与健康相关的行为方面取得的成功有限。与HBM相比，TPB有几个优点。TPB是理性行动理论（TRA）的扩展，增加了感知行为控制这一构念。修订后的模型已被证明比原始的TRA对目标导向行为具有更大的解释力。文中以军事吸烟者戒烟行为研究为例，描述了TPB工具的开发过程。随后讨论了TPB实施过程中的信度和效度问题。当精心实施时，TPB是理解和预测与健康相关行为的有用模型。该模型在制定规范性护理方法方面具有前景。
