Abstract
Background: Many Supplemental Nutrition Assistance Program (SNAP) participants do not consume enough fruits and vegetables (F&V). The transtheoretical model has been used to predict and improve F&V consumption through public health interventions. This study focuses on self-efficacy and decisional balance (perceived benefits and barriers). Measurement scales for each construct have been validated in multiple populations. Repeated analyses of these constructs and measurement scales and their ability to predict F&V consumption will further inform the creation, implementation, and evaluation of nutrition interventions in low-income populations. Purpose: The current study seeks to understand the relationship between decisional balance and self-efficacy and actual F&V intake using previously validated measurement scales. Methods: Seventy-four adults receiving SNAP benefits completed a survey including a food frequency questionnaire (FFQ) for F&V consumption, and previously validated measurement scales for perceived barriers, benefits, and self-efficacy of fruit and vegetable intake. Twenty-four-hour food recalls were also completed using the Automated Self-Administered Assessment tool (ASA24). The relationship between F&V consumption and perceived benefits, barriers, and self-efficacy was analyzed using linear regression and Spearman correlations. Results: Perceived benefits had significant correlations (r=0.5, p=0.01) and regression beta coefficients (B=2.04, p = 0.03) with F&V intake measured by the FFQ, but not the ASA24. Neither perceived barriers or self-efficacy scores had significant associations with F&V intake using either the FFQ or ASA24. Conclusion: Perceived benefits was the only construct with statistically significant associations to F&V intake. Results contrast previous research that found perceived barriers and self-efficacy to be stronger predictors of F&V consumption in the low-income population. This research suggests that perceived benefits of F&V consumption may still be a worthwhile target for nutrition interventions.

The Transtheoretical Model as a Predictor of Fruit and Vegetable Intake in SNAP Participants
