What Is Pure-O?

“Pure-O” is a commonly used term for purely obsessional OCD. However, the term can be misleading. People described as having Pure-O often experience compulsions. The difference is that many of those compulsions occur internally and may not be visible to other people.

Hidden Compulsions

A person might experience an intrusive thought and then spend considerable time trying to determine exactly why it occurred. Mental compulsions can include replaying memories, analyzing thoughts, checking feelings, repeating phrases internally, replacing unwanted thoughts with “good” thoughts, reviewing conversations, testing one’s reactions, and attempting to prove that a feared possibility is not true.

Rumination and OCD

Rumination can become a significant component of the obsessive-compulsive cycle. A person may think, “If I analyze this long enough, I’ll finally figure it out.” Instead, each answer produces another question. The problem therefore becomes less about finding the correct answer and more about the compulsive need to resolve uncertainty.

Why Pure-O Can Be Difficult to Recognize

Visible rituals such as repeated washing or checking are commonly associated with OCD. Mental rituals can be much less obvious. Someone experiencing Pure-O may therefore assume, “I can’t have OCD because I don’t have compulsions.” A careful clinical assessment may reveal numerous covert compulsive behaviors.

Treating Pure-O

Treatment can involve identifying both obvious and hidden compulsions and learning to respond differently to intrusive thoughts. ERP can be adapted to address mental rituals, reassurance seeking, rumination, and avoidance. The objective is not to eliminate every unwanted thought. Instead, treatment can help individuals reduce the importance they assign to those thoughts and stop compulsively trying to solve them.
