Abstract We aimed to compare the history of trauma and the proﬁle and severity of
dissociative symptoms of patients with obsessive-compulsive disorder (OCD) to those of
patients with social anxiety disorder (SAD). Patients with OCD (n = 34) and patients with
SAD (n = 30) were examined with the following instruments: Trauma History Question-
naire (THQ), Dissociative Experience Scale (DES), Obsessive-Compulsive Inventory
(OCI), Liebowitz Social Anxiety Scale (LSAS), Beck Depression Inventory (BDI), and
Beck Anxiety Inventory (BAI). Patients with OCD reported signiﬁcantly lower rates of
exposure to traumatic events. Nevertheless, the severity of dissociative symptoms was not
signiﬁcantly different between the groups. Regression analyses showed that, while the OCI
scores better predicted the variance on DES scores in the OCD sample, the LSAS and the
BAI better predicted the variance on the DES among patients with SAD. Patients with
OCD are probably less vulnerable to some types of traumatic experiences. Dissociative
symptoms may cut across different anxiety disorders.
