Behavioral Change Theories Can Inform the Prediction of Young Adults' Adoption of a Plant-Based Diet
Wyker, Brett A.; Davison, Kirsten K.
Journal of Nutrition Education and Behavior, v42 n3 p168-177 May-Jun 2010
Objective: Drawing on the Theory of Planned Behavior (TPB) and the Transtheoretical Model (TTM), this study (1) examines links between stages of change for following a plant-based diet (PBD) and consuming more fruits and vegetables (FV); (2) tests an integrated theoretical model predicting intention to follow a PBD; and (3) identifies associated salient beliefs. Design: Cross-sectional. Setting: Large public university in the northeastern United States. Participants: 204 college students. Main Outcome Measures: TPB and TTM constructs were assessed using validated scales. Outcome, normative, and control beliefs were measured using open-ended questions. Analysis: The overlap between stages of change for FV consumption and adopting a PBD was assessed using Spearman rank correlation analysis and cross-tab comparisons. The proposed model predicting adoption of a PBD was tested using structural equation modeling (SEM). Salient beliefs were coded using automatic response coding software. Results: No association was found between stages of change for FV consumption and following a PBD. Results from SEM analyses provided support for the proposed model predicting intention to follow a PBD. Gender differences in salient beliefs for following a PBD were found. Conclusions and Implications: Results demonstrate the potential for effective theory-driven and stage-tailored public health interventions to promote PBDs. (Contains 1 figure and 2 tables.)
