Obsessive-compulsive disorder research: Growing in scope, advances unclear.

There has been impressive growth in scholarly research on obsessive-compulsive disorder (OCD). As a general rule, this can be construed as a sign of health in the subspecialty within anxiety disorder research. One factor that likely contributed to the growth in research on OCD was the observation that obsessional experiences can be placed on a dimension from normal to abnormal (or non-clinical to clinical) (Rachman and de Silva, 1978). While the dramatic growth in OCD research has led to increased sophistication in clinical conceptualization of various presentations of this heterogeneous condition, it has not led to a commensurate increase in the availability of efficacious treatment. This gap, between awareness of the disorder and delivery of evidence-based treatment, serves as a limiting factor in enthusiasm regarding the growth in research productivity on OCD as a sign of health in the subspecialty.
