_Human behaviour plays a significant role in most of the leading causes of death. Psychological science has the potential to enhance health outcomes through a better understanding of health promoting and health damaging behaviours. Health psychology and the related field of behavioural medicine focus on the interplay among biological dispositions, behaviour, and social context. The field might advance by building better collaboration with other fields of medicine, sharing expertise on technical aspects of psychometric outcomes assessment, identifying behavioural interventions to reduce (...) health disparities, and creating an infrastructure that fosters multidisciplinary research._.
