Evaluation of metacognitive functions in patients who has delusional disorder and osessive compulsive disorder

Our study aims to evaluate metacognitive functions and clinical characteristics of the patients diagnosed with Obsessive Compulsive Disorder (OCD) and Delusional Disorder (SB) in comparison with the control group . Patients, complying with the inclusion criteria, were chosen from inpatients and outpatients admitted to Fırat University Hospital, Mental Health and Illness Clinic. 50 patients with Obsessive Compulsive Disorder (OCD) and 40 patients with Delusional Disorder (DD) and 50 healthy controls who were matched with patient groups in terms of age and gender were included into study. Structured Clinical Interview Scale for DSM-IV Axis I Disorders (SCID-I), sociodemographical and clinical interview form, metacognition assessment scale -30 (MAS), for OCD patient group additionally Yale-Brown Obsessions and Compulsions Inventory (Y–BOCS) and Obsessive Beliefs Questionnaire-44 (OBQ-44), for DD patients the Brief Psychiatric Rating Scale (BPRS) and Beck Cognitive Insight Scale (BCIS) were administered to patient and control groups. As a result, although metacognition total scores of OCD and DD patients were higher than control group, statistically significant results were determined merely in OCD patients. In OCD patients metacognition uncontrollability and danger together with control need sub dimensions, in DD patients cognitive confidence sub dimension were statistically significant in comparison to control group. Moreover, in OCD patients a positive correlation between Y–BOCS's sub dimension evaluating compulsions and control need, between OBQ-44's sub dimensions perfectionism/precision uncontrollability danger; in DD patients a positive correlation between BCIS's self-expression and cognitive confidence, self-assurance and positive belief sub dimensions were detected. Results of our study put forward that OCD and DD patient groups and control group present differences in terms of MAS parameters. More and more researches need to be carried out in order to determine casual relation between these differences and OCD and DD illnesses.
