A comparative study of obsessive beliefs in obsessive-compulsive disorder, anxiety disorder patients and a normal group.
Giti Shams, Irena Milosevic


Cognitive models of obsessive-compulsive disorder (OCD) posit that specific kinds of dysfunctional beliefs underlie the development of this disorder. The aim of present study was to determine whether these beliefs are endorsed more strongly by OCD patients than by those with other anxiety disorders and by community samples. A battery of questionnaires, including the OBQ-44, MOCI, BDI-II, BAI, STAI, used to assess obsessive-compulsive symptoms, depression and anxiety in 39 OCD patients (OC), 46 anxious patients (AC) and 41 community controls (CC). Compared to CCs and ACs, OC patients more strongly endorsed beliefs related to importance and control of thoughts. Both OC and AC patients scored higher than CC participants did on belief domains about responsibility/threat estimation and perfectionism/certainty. Therefore, the domain that seems to be specific to OCD is a set of beliefs that revolves around the contention that it is possible and necessary to control one's thoughts. Results regarding group differences on particular items of the OBQ-44 indicated that 21 items discriminated between the OC and CC groups and 7 items discriminated between the OC and AC groups, suggesting that these items are more specific to the OC group. Additional research warranted because it is plausible that these cognitive factors relate differently to OCD phenomena across different cultures.
