Extending the Theory of Planned Behavior with the Self-Congruity Theory to Predict Tourists’ Pro-Environmental Behavioral Intentions: A Two-Case Study of Heritage Tourism

Abstract

Tourists’ pro-environmental behaviors are critical to the conservation of cultural landscape heritage and for the sustainability of heritage tourism. Applying the theories of planned behavior (TPB) and self-congruity, this research explained the formation of tourists’ pro-environmental behavioral intentions (TPEBI). A total of 342 effective responses were gathered at a heritage destination, while another set of data was collected from a historic cultural destination for cross-validation (n = 345). The findings indicated that: (1) there are direct and positive associations between TPEBI and attitudes toward the behavior, subjective norms, perceived behavioral control, self-congruity, and functional congruity; (2) functional congruity mediates the association between self-congruity and TPEBI; (3) the “congruity-TPB” framework has greater predictive capacity in comparison to the single model; (4) a cross-validation approach found consistent results by using a historic cultural district as another case. Taking both rational and value-expressive factors into consideration, the current study expands the applicability of the self-congruity theory in TPEBI research. Findings produce some new insights into sustainable destination management.
