Res Nurs Health. 1991 Apr;14(2):137-44. doi: 10.1002/nur.4770140208.


The Theory of Planned Behavior (TPB) is an expectancy-value theory that provided a framework for the study of behavioral and normative beliefs affecting health behaviors. The purpose of this article is to describe operationalization of the TPB. The process of instrument development is explicated, with examples from two studies of BSE behavior in older women. Potential threats to reliability are discussed.
