Abnormal affect in OCD has been hypothesized to result from dysfunction in the OFC, ventral striatum, and amygdala. OCD is characterized by high levels of anxiety, high rates of comorbidity with major depressive disorder, and blunted response to reward. This is reflected by reduced amygdala and ventral striatum response to positive stimuli, and ...

One explanation for the high depression rate among OCD populations was posited by Mineka, Watson and Clark (1998), who explained that people with OCD, or any other anxiety disorder, may feel "out of control ...
Items for the DOCS were generated on the basis of research on the dimensionality of OCD symptoms [10] as well as on the parameters of OCD symptom severity. [12] After writing an initial draft of scale items and instructions, the DOCS authors obtained feedback regarding the clarity, reading level, and relevance of these materials from a larger group of (a) experts on OCD, (b) experts on scale ...
When OCD becomes severe, this leads to more interference in life and continues the frequency and severity of the thoughts the person sought to avoid. [21] Exposure therapy (or exposure and response prevention) is the practice of staying in an anxiety-provoking or feared situation until the distress or anxiety diminishes.
The Yale–Brown Obsessive–Compulsive Scale (Y-BOCS) is a test to rate the severity of obsessive–compulsive disorder (OCD) symptoms.. The scale, which was designed by Wayne K.
