Abstract:
According to self-determination theory (SDT; Ryan & Deci, 2000), the quality of support (autonomy support versus controlling) from important others is an important predictor of psychological need satisfaction, and subsequent engagement in health-conducive behaviours, such as physical activity and healthy eating. In this dissertation, four research studies grounded on SDT are presented. Results from these studies highlighted the important link between autonomy support and psychological need satisfaction. In turn, these studies showed that need satisfaction supported better psychological well-being and health-conducive behaviours. The findings also underscored the detrimental effects of controlling behaviours. For instance, such behaviours were found to be related to the thwarting of psychological needs, and in turn higher psychological ill-being and maladaptive outcomes, such as unhealthy eating behaviours. Motivation contagion effects were also examined in one study. The results suggested that practitioners’ quality of support provided may vary as a function of their perceived motivation of a client. Findings from our studies have implications for researchers and important others (e.g. spouse) of individuals engaging in weight management. Possible areas for future research, such as the design of new interventions based on the tenets of SDT, are discussed.
