Obsessive-compulsive disorder is a heterogeneous disorder. While significant variability exists between the overarching content themes of obsessions (e.g., obsessions regarding aggression, contamination, religion), great variability also exists within the specific subcategories. For example, some ways in which aggressive obsessions manifest include fear of: 1) harming self, 2) harming others intentionally, 3) harming others accidently, 4) violent images, 5) blurting insults, 6) acting on unwanted impulses, 7) stealing things.
