Objective : The purpose of this study was to identify specific beliefs regarding eating two cups of fruits among ninth-grade youth attending public high schools in easternNorth Carolinautilizing the Theory of Planned Behavior (TPB). Methods: A preliminary open-ended questionnaire was used to elicit beliefs about fruits. These beliefs along with statements adopted from the literature tailored toward fruit intake were used to develop a survey instrument. This survey was subsequently used to measure the variables of the TPB. There were 157 students (103 girls [65.6%], mean ±SD age =14.69 ±0.79 and 54 boys [34.4%], mean ±SD age =14.74 ±0.89) from two schools who completed the final copy of the survey. Results: Attitude, subjective norms, and perceived behavioral control significantly predicted intention to eat fruits, accounting for 55% of variance. Conclusion: The findings of this research suggest that peer leaders may have a significant influence on intentions to eat fruits.
