When assessing and monitoring progress with OCD sufferers, originally I used the Y-BOCS questionnaire. Then some years ago I switched to using the OCI (distress scale). This is fine ... it's the officially recommended OCD questionnaire by IAPT, the English Increasing Access to Psychological Therapies initiative (see pages 39-41 of their freely downloadable Appendices and helpful resources manual). But a hassle about the 42-item OCI is that it's time consuming, taking about 12 minutes to complete and a fair amount of time to review & score. I've now shifted to using the 18-item OCI-R (see Veale et al, 2016 below).
