The symmetry dimension is highly prevalent in obsessive-compulsive disorder (OCD), affecting 86.8% of patients. It is associated with earlier symptom onset, more severe depression, and sensory phenomena.
Area of Science:
- Psychiatry
- Clinical Psychology
- Neuroscience
Background:
- Obsessive-compulsive disorder (OCD) is a heterogeneous condition with various symptom dimensions.
- The symmetry dimension includes obsessions/compulsions related to symmetry, ordering, repetition, and counting.
Purpose of the Study:
- To investigate the prevalence, severity, and correlates of the symmetry dimension in OCD patients.
- To analyze demographic and clinical factors associated with the symmetry dimension.
Main Methods:
- Cross-sectional study of 1001 outpatients from the Brazilian Research Consortium on OCD Spectrum Disorders.
- Utilized Yale-Brown Obsessive-Compulsive Scale, Beck Depression and Anxiety Inventories, and other standardized assessments.
- Employed bivariate analyses and logistic regression to identify correlates.
Main Results:
- The symmetry dimension was highly prevalent (86.8%) in the sample.
- Associated with earlier onset of OCD symptoms and insidious onset of compulsions.
- Linked to more severe depressive symptoms and the presence of sensory phenomena.
Conclusions:
- Understanding specific OCD dimensions, like the symmetry dimension, is crucial for effective management.
- Highlights the importance of recognizing associated factors such as depression and sensory phenomena.
