Laveurs, vérificateurs, ruminateurs : spécificité des croyances dysfonctionnelles, des obsessions et des compulsions ?

The Padua inventory and the two questionnaires OBQ and III discriminated between French OCD and non clinical controls. In the OCD sample, the three subtypes (washers, rumination and checkers) did not differ from each other on total YBOCS score and total Padua score. The “washer” subjects scored higher than both “checker” subjects and subjects with rumination on the washing scale of the Padua inventory. The “checker” subjects scored higher than the two other subtypes on the checking scale. The impaired mental control and urges and worries of losing control scales failed to discriminate between the subjects with rumination and the two other (checking and washing) subtypes. The OBQ total and the six subscale scores failed to discriminate between the three OCD subtypes. These results were replicated with the III. The ANOVAs revealed that the participants in the rumination symptom subtype scored higher only on the importance/control of thoughts of the OBQ-44 than the participants in the checking subtype. Implications for future research are discussed.
