Health psychology theories and models of behaviour

Abstract

Theories, models, and their application are a crucial part of the development and growth of health psychology. This chapter contextualises health psychology in its foundations of the biopsychosocial model and discusses, non-exhaustively, key theories, models, and concepts used in the field relating to behaviour. The development of theories and models over the decades will be presented, showcasing the movement from cognitive to socio-cognitive, self-regulation to whole systems approaches, and where they are applied, to include individuals, populations, environments, behaviours, and conditions. This chapter will help to situate health psychology in the health and social care system, and critically discuss its contribution to science, education, policy, and practice
