The intent to ‘figure it out’ is the compulsion. Response prevention is dropping the analysis mid-sentence — even if the answer feels one thought away.

About this worksheet

'Pure-O' is a common but misleading label. There are always compulsions in OCD — in 'Pure-O' presentations they are simply mental: silent review of past events for proof, silent repetition of prayers or phrases, arguing with the intrusive thought, mental checking of body sensations or feelings, self-reassurance ('I would never…'), neutralizing a 'bad' thought with a 'good' one. Because the rituals are invisible, clients often plateau in treatment — the behavioral compulsion has been reduced, but the mental one has taken its place. This tracker makes the invisible ritual visible. It gives clients a checklist of common mental compulsions so they can recognize their own, then a daily log with trigger, mental compulsion, duration, and the response-prevention move. The core clinical rule is at the bottom: if you are analyzing, you are compulsing. Response prevention for mental compulsions is dropping the analysis mid-sentence, even if the answer feels one thought away. Draws from Grayson, Hershfield, and Abramowitz on mental-compulsion ERP.

When to use it

Clients who report 'thoughts only' OCD.
Clients who have reduced behavioral compulsions but remain distressed — mental rituals have taken over.
Rumination presentations that meet OCD criteria (as opposed to depressive rumination).
Requires ERP training. Mental-compulsion ERP is harder than behavioral and often needs specialist supervision.

How to use it

1
Normalize the label
'Pure-O' is a misnomer — there are always compulsions, just internal. This reframing itself often unlocks treatment.
2
Catalogue mental compulsions
The checklist prompts recognition of rituals clients often haven't named. Many are surprised to find they perform six or seven categories.
3
Log daily with duration
Trigger, compulsion, duration in minutes, response instead. Duration is important — mental compulsions often eat hours.
4
Practice the replacement move
'Maybe, maybe not — moving on.' Delivered mid-analysis, even if the answer feels imminent. This is the mechanism.
5
Notice the slip
Clients need to catch themselves sliding back into mental analysis. Naming the slip is the first response-prevention move.

Frequently asked questions

What is Pure-O OCD?+

A term used for OCD presentations in which the compulsions are mental rather than behavioral — silent review, mental checking, self-reassurance, neutralizing. The term is misleading because there are always compulsions; they are just internal.

How is Pure-O treated?+

With standard ERP adapted for mental compulsions. The exposure is the intrusive thought; the response prevention is refusing to analyze, review, or neutralize it. Harder than behavioral ERP because the ritual is invisible to observers.

How do I know if I'm ruminating or having a real thought?+

By function. Rumination is repeated, driven by anxiety, and produces relief. A real thought is generative, moves forward, and does not repeat the same content. If you notice you have thought this exact thing many times before, it's a compulsion.

Is Pure-O the same as intrusive thoughts?+

No. Intrusive thoughts are the obsessions. Pure-O is a shorthand for OCD presentations in which the response to the intrusive thoughts is mental rather than behavioral.
