OBSESSIVE-COMPULSIVE DISORDER WITH AND WITHOUT A CHRONIC TIC DISORDER- A COMPARISON OF SYMPTOMS IN 70 PATIENTS

The phenomenological features of 35 obsessive-compulsive disorder (OCD ) patients with a lifetime history of ties were compared to 35 age- an d sex-matched OCD patients without tics. Seven categories of obsession s and nine categories of compulsions were determined using the symptom checklist of the Yale-Brown Obsessive-Compulsive Scale (YBOCS). Discr iminant function analysis revealed that, compared to their counterpart s without tics, OCD patients with tics had more touching, tapping, rub bing, blinking and staring rituals, and fewer cleaning rituals, but di d not differ on obsessions. These preliminary findings suggest that th e types of compulsions present may help to discriminate between two pu tative subgroups of OCD, i.e. those with and without tics.
