Perceived Behavioral Control and Habit are Potential Factors in Reducing Plate Waste Practices #

Abstract

This study aimed to determine factors related to the practice of plate waste by combining the Theory of Planned Behavior (TPB) construct and other variables related to eating behavior. The variables studied are knowledge, perceived behavioral control, subjective norms, attitude, intentions, habits and hunger levels. This study used a cross-sectional design with a sample size of 140 high school students. Knowledge, perceived behavioral control, habit, hunger level and food preference are significant variables to influence in reducing plate waste while the other variables had no influence. Perceived behavioral control, habit and hunger level have strong relationship toward plate waste decrease.
