Insight: Occasionally, the line can be blurry. However, basically, an obsession is a thought you know doesn't make sense and a delusion is a fixed false belief that you completely believe regardless of evidence against it.

Exactly that!: In schizophrenia, there is a break from reality, while psychosis is not a major symptom of ocd.

OCD: Also, OCD maintain insight, while schizophrenia lack insight.
Dr. Kevin Passer
Child Psychiatry 35 years experience
Insight: People with obsessions realize that their thoughts are unreasonable and unrealistic and have insight into their thoughts. By definition, a delusion is a false belief but a person thinks it is true. Ocd is considered an anxiety d/o whereas delusions are a problem with one's thoughts.

Sometimes a person with psychosis (delusional thoughts) may be obsessive in their beliefs (eg. that they are being watched) and they dwell on these thoughts relentlessly. The core issue is psychosis but it may present as an obsession.
