Abstract

Background: Given the very limited data, this study aimed to determine the applicability of the Theory of Planned Behaviour (TPB: Ajzen, 1991) in the study of high-fat snacking in Greek high-school students, whilst taking into consideration gender and culture-relevant factors. Methods: Predictor variables were measured at Time 1 (N=147), and actual high-fat snacking a week later (N=129). Additionally, three focus groups (N=28) were conducted to elucidate culture-relevant factors influencing high-fat snacking. Findings: The TPB variables predicted 19.6% of intended high-fat snacking, with attitudes being the strongest predictor (? =.40, p< .001). Moreover, the model predicted 35% of subsequent high-fat snacking. Gender did not influence intended or subsequent high-fat snacking. Of the culture-relevant influences, the involvement of grandmothers and the 24-hour easy access to snacks at kiosks were particularly salient. Discussion: The TPB can be used to study high-fat snacking among Greek students, whilst accounting for culture-relevant influences.
