Key Differences

Compulsive or repetitive behaviours
Obsessive-Compulsive Disorder (OCD): Core
Generalized Anxiety Disorder: Associated

Intrusive unwanted thoughts
Obsessive-Compulsive Disorder (OCD): Core
Generalized Anxiety Disorder: Common
Explanation: In OCD, unwanted thoughts tend to feel more intrusive, distressing, and difficult to dismiss, while in generalized anxiety they more often blend into ongoing worry.
Perfectionism
Obsessive-Compulsive Disorder (OCD): Core
Generalized Anxiety Disorder: Common
Explanation: In OCD, perfectionism is more likely to feel rigid, urgent, and tied to preventing distress or mistakes, while in generalized anxiety it is more often part of broader worry about outcomes.
Excessive guilt
Obsessive-Compulsive Disorder (OCD): Core
Generalized Anxiety Disorder: Common
Explanation: In OCD, guilt is more likely to attach intensely to feared thoughts, doubts, or perceived responsibility, while in generalized anxiety it is usually part of a wider pattern of worry and self-criticism.
Difficulty making decisions
Obsessive-Compulsive Disorder (OCD): Core
Generalized Anxiety Disorder: Common
