There has been considerable debate with respect to the relationship be
tween Obsessive Compulsive Disorder (OCD) and psychotic phenomena. In
the present study, a large sample of subjects suffering from OCD compl
eted a self report instrument of features associated with Schizotypal
Personality Disorder. A systematic and positive relationship was found
between the presence of schizotypal features and OCD, independent of
the effects of depression and anxiety. Moreover, consistent with previ
ous experimental work, the presence of schizotypal features predicted
the presence of obsessional phenomena attributable to reduced cognitiv
e inhibition. (C) 1997 John Wiley & Sons, Ltd.
