Voluntary cooperation is crucial in determining the effectiveness of a health promotion strategy. The Triandis model, a theoretical model with the advantages of the Fishbein model, is useful in directly explaining health behavior. The purpose of this study was to perform a comprehensive evaluation of behavioral tendency related to health promotion and to examine the interrelationship amongst factors related to health behavior. This study uses the Triandis model to examine the structural relationship between explaining variables of health promotion. Five-hundred and nine residents were selected by multi-stage random sampling from the province of Kyungi-do, Korea. A structured questionnaire based on the Triandis model was developed. This questionnaire was distributed to the selected residents and their responses were collected via face-to-face interviews. The results showed that expectation of behavioral consequence, social norm and age variables were significantly related to health behavioral tendency. In addition, facilitating factors, affect variable and education level were indirectly related to health behavior. The results suggest that integrating behavioral subsets may be useful for understanding the mechanism of individual health promotion behavioral tendency.
