Behaviour Research and Therapy
|March 1, 1994
Summary
Obsessive-compulsive disorder (OCD) beliefs exist on a continuum, not a simple yes/no insight scale. Understanding this spectrum is key for effective treatment of obsessive-compulsive disorder.
Area of Science:
- Psychiatry
- Clinical Psychology
- Neuroscience
Background:
- Prevailing view: OCD patients recognize obsessions as senseless.
- Clinical observation: Some OCD patients view symptoms as reasonable or delusional.
- Existing concepts: Obsessions, overvalued ideas, and delusions require comparison.
Purpose of the Study:
- Compare concepts of obsessions, overvalued ideas, and delusions.
- Review studies on insight in obsessive-compulsive disorder (OCD).
- Determine if insight dichotomizes OCD symptoms.
Main Methods:
- Literature review of insight in OCD.
- Conceptual analysis of obsessions, overvalued ideas, and delusions.
- Examination of theories of delusion formation in OCD.
Main Results:
- OCD ideas cannot be dichotomized by patient insight.
- A continuum of belief strength is a more fitting model for OCD.
- The link between conviction strength and therapy outcome is unclear.
Conclusions:
- Insight is not a simple binary in OCD; a continuum model is better.
- Further research needed on conviction strength and therapeutic outcomes.
- Delusion theories may inform understanding of OCD development.
