Reduced Design Fluency in Subclinical Obsessive-Compulsive Subjects

This study examined the verbal and design fluency abilities of 25 subclinical obsessive-compulsive (OC) subjects and 27 noncompulsive control subjects. As hypothesized, the OC group showed reduced design fluency, and design fluency was also negatively correlated with obsessionality. These results provide further evidence for the involvement of the right corticostriatal systems in the mediation of OC behaviors, extending the findings to individuals with subclinical symptoms.
