In this chapter we outline the treatment of children and adolescents with somatising conditions. The major diagnostic groups for these conditions (according to ICD-10; World Health Organization, 1992), in approximate descending order of prevalence, are adjustment, dissociative (conversion), somatoform and factitious disorders, and neurasthenia (chronic fatigue syndrome). The aetiology and clinical presentations of these disorders are discussed in Chapter 12, together with descriptions of the corresponding disorders in DSM-5 (American Psychiatric Association, 2013). Despite work in the past decade on the treatment of recurrent abdominal pain (Campo et al, 2004; Walker et al, 2006) and chronic fatigue (Rangel et al, 2000a; Garralda & Chalder, 2005), somatising conditions remain an area in which there is little systematic treatment research. Epidemiological studies give us a broad description of outcomes (Lieb et al, 2000; Kozlowska, 2001; Chalder et al, 2003; Ani et al, 2013) and there are many useful clinical accounts of the management of these disorders (Wright et al, 2000; Kozlowska et al, 2007; Fiertag et al, 2012).

Which professional should manage somatising disorders?

The decision about the appropriate clinician to manage a somatising disorder should depend on who has the skills to maximise the chances of recovery to normal functioning. This depends on the severity of the presentation, its impact on the young person's current functioning and how long symptoms have lasted.

Paediatricians and general practitioners (GPs) undertake the management of many adjustment, dissociative (conversion) and factitious disorders, and mild relapses of any somatising conditions. The presentations they manage are most likely to be of single or multiple physical symptoms (abdominal pain, joint pains, headaches), fatigue associated with obvious stresses of any kind, recent-onset losses of function, and unexplained symptoms after a clear physical illness. Their management forms a routine part of primary care and paediatric practice. Key elements of management in paediatric and primary care are listed in Box 13.1.
