Social contextual and environmental determinants of physical activity adoption, adherence and well-being

[摘要] Over two thirds of the UK population do not meet physical activity (PA) recommendations set by the Department of Health (2011) to improve or maintain health. It is therefore essential to focus research on effective and efficient methods to promote autonomous reasons to engage and persist in PA. Employing a variety of research designs this thesis explores the social contextual and environmental determinants, predominantly from a Self-Determination Theory perspective, of PA adoption, persistence and psychological well-being (Study 1; qualitatively). Study 2 and 3 examined unique sources of support from within and beyond a PA programme including human and non-human sources (i.e., technology). Study 3 employed an intervention focusing on the effect of autonomy supportive text messages on PA behaviour and well-being. Deriving from findings of Study 1, the final study (4) investigated the effect of the physical environment and PA levels on affective states. Results highlight the importance and relevance of socio-contextual (considering each unique contribution of individual sources of support) and environmental determinants (moderate intensity PA within a natural outdoor environment being key for positive high activation) in the promotion of PA. Findings carry important practical implications for those involved in promotion of long-term PA behaviour.
