A major contemporary cognitive model is that developed by
the Obsessive Compulsive Cognitions Working Group (26-
28), This intemational group of over 40 investigators shares
an interest in understanding the role of cognitive factors in
OCD, Extending the work of Salkovskis and others, they have
reached a consensus regarding the most important underlying
beliefs in OCD (26), They identified responsibility beliefs and
other belief domains (listed in Table 1) that were said to give
rise to corresponding appraisals. Two self-report measures—
the Obsessional Beliefs Questionnaire and the Interpretations
of Intmsions Inventory—were developed to assess these
domains (27),
