OCD Test (OCI) — Free Obsessive Compulsive Inventory Online

The 7 OCI subscales

The OCI measures seven OCD symptom domains. Most people with OCD have one or two dominant subscales and lower scores on the rest.

• Washing — contamination-focused; fear of germs, illness, environmental toxins; washing or cleaning rituals
• Checking — fear of harm or mistakes; checking locks, appliances, work, body
• Doubting — uncertainty about whether you have done something correctly or remembered something accurately
• Ordering — symmetry and "just right" concerns; arrangement, alignment, completion rituals
• Obsessing — primarily mental obsessions; intrusive unwanted thoughts; the subscale closest to Pure O
• Hoarding — difficulty discarding; accumulation of possessions
• Neutralising — mental rituals done to undo or counteract intrusive thoughts (mental review, neutralising thoughts, repeating phrases)

Subscale scores help target treatment. Washing-dominant OCD has different ERP exposures than checking-dominant; both have different exposures than obsessing-dominant.

OCI score interpretation

The OCI is most useful when interpreted by a clinician trained in OCD assessment — both the total score and the subscale pattern matter. As a general guide:

• Low scores — symptoms below clinical threshold; if you have specific concerns the OCI did not surface, consider the VOCI (Pure O) or ROCI/PROCSI (Relationship OCD)
• Elevated scores — clinical evaluation by an ERP-trained clinician recommended

Result pattern	What it suggests	Suggested next step
Low total, no subscale stands out	Few OCD-type symptoms right now	No action needed; re-take if symptoms change
One or two subscales clearly higher than the rest	A specific symptom pattern (for example washing or checking)	Read about OCD; discuss with a clinician if it causes distress or takes time each day
High total with several raised subscales	Broad, significant OCD-type symptoms	Book an assessment with an ERP-trained clinician, who may rate severity with the Y-BOCS

This is how Mindtalk presents results, not a clinical cut-off for the 42-item OCI. The best-established screening cut-off (a score of 21) belongs to the shorter 18-item OCI-R.

OCD diagnosis requires comprehensive clinical assessment beyond a screener. The OCI identifies people who would benefit from that assessment.

Who should take the OCI

• People who spend significant time each day on intrusive thoughts, checking, washing, ordering or mental rituals
• People who suspect OCD but are unsure which pattern fits
• People already in ERP who want a simple way to track change between sessions

The OCI does not tell you whether symptoms come from another condition (for example, anxiety, depression or a medical issue), and it cannot rate severity the way a clinician-administered Y-BOCS interview can.

What ERP therapy actually looks like

ERP (Exposure and Response Prevention) is the gold-standard OCD treatment. Edna Foa, the OCI's lead author, is one of the researchers who refined and tested it. The therapist helps you gradually face the situations or thoughts that trigger your obsessions without doing the compulsion. Over time, the brain learns that the feared outcome does not happen, and the distress reduces.

Counter-intuitive but extremely effective — meta-analyses show large effect sizes for OCD across subtypes. Typical course — 12-20 sessions for moderate OCD, longer for severe or complex presentations. Medication (typically SSRIs at higher doses than for depression) is often combined for moderate-to-severe OCD. Combination treatment produces the strongest outcomes.

Common OCD myths

• "OCD is about being tidy" — false. It is about distress and compulsion.
• "If I have intrusive violent or sexual thoughts, I am a dangerous person" — false. People with OCD are not at higher risk of acting on intrusive thoughts.
• "Talking about my intrusive thoughts will make them worse" — false. Clinical disclosure to a trained therapist is the first step in treatment.
• "OCD goes away on its own" — usually false. Untreated OCD is typically chronic.
• "Medication is the first treatment" — false. ERP therapy is first-line; medication is added or used in combination.

Pair with related Mindtalk tools

• The full OCD assessments category covers 5 OCD-specific screeners including the VOCI (better for Pure O), ROCI/PROCSI (Relationship OCD), and OBQ-44 (underlying cognitive beliefs)
• For OCD content overlapping with anxiety, the GAD-7 gives a complementary read on generalised anxiety
• The CBT Thought Record worksheet and Cognitive Distortions worksheet underpin the cognitive side of CBT (note — ERP is the OCD-specific gold standard, not generic CBT alone)
• For acute distress when obsessions are spiking, the Emergency Reset audios (grounding, breathing) can help you tolerate the urge to compulse long enough to defer it

Validation and evidence

Edna Foa and colleagues introduced the 42-item OCI in 1998 as a self-report measure covering seven OCD symptom areas. In 2002 the same group published the 18-item OCI-R, testing it in 215 people with OCD, 243 with other anxiety disorders and 677 non-anxious adults. The OCI-R kept strong psychometric properties and separated OCD from the other groups well. A 2006 clinical replication confirmed its six-factor structure and its ability to tell OCD apart from other anxiety disorders. A Sinhala-language validation (published in the Indian Journal of Psychiatry) found a cut-off of 21 gave 84.4% sensitivity and 85.6% specificity against psychiatrists' diagnosis.
