Medically unexplained somatic complaints are among the most common clinical presentations in primary care in developing countries and they are a considerable burden for patients and the healthcare system. They are assumed to be the result of psychosocial factors, and the process by which symptoms are experienced is termed somatisation. Common mental disorders, somatoform disorders and socio-economic adversities are the major risk factors for these complaints. There is evidence suggesting that cognitive–behavioural therapy, which has proven efficacy for somatoform disorders in the developed world, can be used in developing countries with some adaptations (e.g. by simplifying the content so that it can be applied in primary care by non-specialist health practitioners; using culturally appropriate analogies; and delivering the intervention over fewer and shorter sessions). The main components of such an intervention are presented in this article.
