In addition, we intend to expand the understanding of clinical and demographic characteristics that influence decision-making. METHOD: Our sample consisted of 214 subjects (107 diagnosed with OCD and 107 healthy controls) who were evaluated on their clinical, demographic and neuropsychological features. Moreover, the Iowa Gambling Task (IGT), a task that detects and measures decision-making impairments, was used. RESULTS: We found that OCD patients performed significantly worse on the IGT. Furthermore, features such as symptoms of anxiety did not influence IGT performance. CONCLUSION: Impaired decision-making seems to be a key feature of OCD. Given that OCD is a complex heterogeneous disorder, homogeneous groups are necessary for an accurate characterization of our findings.<\/jats:p>","DOI":"10.1590\/s0004-282x2011000500013","type":"journal-article","created":{"date-parts":[[2011,8,25]],"date-time":"2011-08-25T14:16:26Z","timestamp":1314281786000},"page":"642-647","source":"Crossref","is-referenced-by-count":45,"title":["Decision-making
