This review of the literature on obsessive compulsive disorder (OCD) presented
diagnostic, epidemiological, and conceptual features of the disorder. It highlighted the
heterogeneity of OCD by discussing the various symptom subtypes, spectrum
disorders and comorbid conditions. Consideration of the prevalence, severity,
chronicity, intensity, complexity and pervasiveness of OCD demonstrated it to be a
significant clinical problem. Biological, psychological and environmental aetiological
and maintenance factors were presented, establishing that no single theory can account
for the onset and maintenance of the disorder in all cases. A dominant hypothesis
arising from cognitive and behavioural conceptualisations, as well as
phenomenological accounts of OCD, was that of anxiety reduction. Cognitive,
affective, behavioural and psychophysiological components of anxiety reduction were
discussed in relation to obsessions and compulsions. Research into the anxiety
reduction processes associated with these phenomena was deemed to be useful in
clarifying the maintenance mechanisms underlying the disorder. However, such
research has been limited by insufficient or desynchronous response components and
the methodology to measure actual obsessive-compulsive episodes. Of the anxiety
disorders, OCD presents as one of the most complex and diverse forms of
psychopathology, both to treat and to investigate.
