An extension of the theory of planned behavior to predict immediate hedonic behaviors and distal benefit behaviors

Abstract

The importance of understanding different behavior types is fundamental to changing patterns of dietary consumption toward optimal health. This study investigates fruit and vegetable (F&V) consumption as a distal benefit behavior and snacking as an immediate hedonic behavior, within the framework of the theory of planned behavior (TPB; Ajzen, 1991). The model was extended to examine the predictive value of past behavior and self-regulatory ability across these two dietary behaviors. A total of 190 undergraduate students from an Australian university were administered two online questionnaires over two measurement points with 1-week interval. At time one, participants completed TPB questionna..
