SCHIZOTYPAL FEATURES IN OBSESSIVE-COMPULSIVE DISORDER

This study examined the prevalence and nature of schizotypal features in obsessive-compulsive disorder (OCD). Although this symptom pattern has been related retrospectively to treatment resistance, no prospective data have addressed such an hypothesis. This study sets the stage for further work in this arena by prospectively identifying and characterizing a schizotypal subset of OCD patients. Twenty-eight percent of the sample had schizotypal features, although only 8% met criteria for schizotypal personality disorder. Social-evaluative concerns and psychotic-like symptoms characterized this subgroup. Schizotypal patients did not differ from nonschizotypes with regard to anxiety, depressive, or obsessive-compulsive symptoms. © 1990.
