This review indicates that future studies should distinguish among apparent obsessive-compulsive symptoms (OCS) that occur only in the context of psychosis and that may overlap with psychotic phenomenology, representing a forme fruste of psychosis.

Obsession severity was found to significantly predict patient QOL, whereas the severity of compulsive rituals did not impact on QOL ratings, and treatments that directly target obsessions and secondary depression symptoms in OCD are warranted.
