Behavioural Medicine: Strengthening approaches to address co-morbid chronic physical and mental disorders

South Africa is confronted with multi-morbid chronic physical and mental disorders. The relationships between these conditions are often multidirectional and result in a variety of adverse mental and physical health outcomes. The risk factors and perpetuating conditions in multi-morbidity are potentially modifiable through effective behaviour change. However, in South Africa, interventions and clinical care that address these co-occurring factors have traditionally functioned in a vacuum, created by a lack of formalised multidisciplinary collaboration. In high-income settings, the field of Behavioural Medicine was established in recognition of the importance of psychosocial factors in illness and assumes that the presence of physical concerns can be influenced by psychological and behavioural factors. The large body of evidence supporting Behavioural Medicine has afforded the field global recognition. Yet, it remains an emerging field in South Africa and on the African continent. The purpose of this paper is to contextualise the field of Behavioural Medicine in South Africa and present a way forward to establish the field in our context.
