Testing an integrated model of the theory of planned behaviour and self-determination theory for different energy balance-related behaviours and intervention intensities Hasselt University Ghent University
Objectives The aim of the study was to test the relations between constructs from the self-determination theory (autonomous and controlled motivation), the theory of planned behaviour (attitudes, self-efficacy, and intentions), and behaviour change within a theoretically integrated model. Additionally, the aim was to test if these relations vary by behaviour (physical activity or dietary behaviour) or intervention intensity (frequency). Design ...
