Explain one similarity and one difference between the Maudsley Obsessive-Compulsive Inventory (MOCI) and the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS).
Similarities could include-
· Both do a quantitative measure
· Both a useful diagnostic tool (or useful to use during therapy to assess symptoms)
· Both have good levels of concurrent validity
· Offer good test re-test reliability
· Subjective tests as it requires the patient with OCD to give honest and accurate responses
Differences could include –
· The Y-BOCS takes longer (about 30 minutes) as opposed to the 5 minutes for the Maudsley.
· Scores range from 0–30 Maudsley and 0–40 (Y-BOCS).
· Y-BOCS is semi-structured interview plus the questionnaire whereas Maudsley is a questionnaire
· Y-BOCS collects qualitative as well as quantitative measures whereas Maudsley is just quantitative.
· Y-BOCS has a children’s version and the Maudsley does not (although can be used with children)
