Behavioral Change Theories Can Inform the Prediction of Young Adults' Adoption of a Plant-based Diet

Objective: Drawing on the Theory of Planned Behavior (IPB) and the Transtheoretical Model (TTM). this study (1) examines links between stages of change for following a plant-based diet (PBD) and consumering more fruits and vegetables (FV). (2) tests an integrated theoretical model predicting, intention to follow a PBD, and (3) identifies associated salient belief's Design: Cross-sectional Setting: Large public university in the northeastern United States Participants: 204 college students Main Outcome Measures: TPB and TIM 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 Nil) 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
