OCI-R: Obsessive-Compulsive Inventory-Revised

Overview

The OCI-R asks about distress from 18 obsessive-compulsive symptoms during the past month. Three items form each of six 0-to-12 subscales, and all 18 values add to a 0-to-72 total. The score can organize an OCD assessment, but it cannot diagnose a condition or determine care by itself.

The pattern matters too.

What the OCI-R measures

The original validation study developed the 18-item OCI-R from the longer Obsessive-Compulsive Inventory. It removed the separate frequency scale and simplified subscale scoring.

The six subscales are:

• Washing
• Obsessing
• Hoarding
• Ordering
• Checking
• Neutralizing

Each item uses a 0-to-4 distress value. Survey Doctor requires all 18 answers and applies no reverse scoring.

How scoring works

Each subscale adds its three assigned items. The six subscale totals then add to the overall score.

Six distinct parts. One summed total.

The same total can come from one concentrated area or several smaller subscale scores. Review both levels before drawing a conclusion.

Screening cutoffs

The original study included 215 adults with OCD, 243 with another anxiety disorder, and 677 nonanxious participants. It reported different total cutoffs for different comparisons: 21 against the nonanxious group and 18 against the other-anxiety group.

Neither number is a diagnosis. A useful cutoff depends on the population, why screening is being done, and what fuller assessment follows.

Thresholds answer differently.

Below-cutoff symptoms can still matter when they consume time, cause distress, or interfere with daily life.

Research severity ranges

A 2020 study compared OCI-R totals with Y-BOCS groups in 1,339 treatment-seeking adults who already had OCD. It proposed these research ranges:

The study cautioned that classification was weaker at the higher boundary. These ranges describe its clinical sample. They do not confirm OCD, select treatment, or show that a low score means no care is needed.

Current label boundary

The current OCI-R score key uses the 2020 ranges, but older stored results may carry labels from a superseded four-band scheme. The product therefore withholds OCI-R total labels from result, report, and export paths until those histories can be distinguished safely.

History blocks labels.

The numeric total and six subscales remain available. Keep the number and date when comparing results, and confirm that both records used the same form and scoring rules.

Using the result

The OCI-R does not measure every part of an OCD assessment. It does not directly establish time spent, functional impairment, insight, or alternative explanations.

Use the item and subscale pattern to guide a fuller conversation. A change over time describes a change in reported distress; it does not prove why the change occurred.

Related assessment

The DOCS groups obsessive-compulsive symptoms into four broader dimensions and asks about time, avoidance, distress, interference, and resistance. Its score is not convertible to the OCI-R total, and the digital DOCS form has separate implementation limits.
