DISORDER IN CHILDREN AND
Obsessive-compulsive disorder (OCD) is estimated to affect 0.5–2% of children and adolescents, and the phenomenology of OCD in children and adults is highly similar (Swedo et al., 1989b). Given the apparent continuum between the forms of OCD across the age range, it is not surprising that similar psychological and pharmacological interventions are used (Franklin et al., 1998). Nevertheless, significant differences exist in terms of the gender distribution of the disorder, co-morbidity, familial contribution, developmental issues and theories of maintenance. These differences have led to some proposals that childhood OCD is a distinct subtype of adult OCD (Geller et al., 1998) and it is argued that it can be viewed within the framework of paediatric auto-immune neuropsychiatric disorder associated with infection (Swedo et al., 1998). The chapter begins by describing the epidemiology and phenomenology of the disorder and assessment techniques. Psychological and neuropsychiatric theories of the disorder are discussed, and treatment outcome studies reviewed. The chapter concludes by calling for a closer integration between the science and practice of treating OCD in young people.
Early prevalence estimates of OCD from child psychiatric clinics ranged from 0.2% to 1.2% (Berman, 1942; Hollingsworth et al., 1980; Judd, 1965) but more recent studies of adolescents in the community find prevalence rates ranging from 1–4% (Douglass et al., 1995; Flament et al., 1988;
