Relationship between the obsessional beliefs questionnaire and the Yale Brown Obsessive Compulsive Scale in patients in intensive residential treatment

This study examined the relationship between the changes in Yale-Brown Obsessive Compulsive Scale-Self Report (YBOCS-SR) and Obsessional Beliefs Questionnaire-44 (OBQ-44) scores at admission in adult patients (N = 42) with obsessive-compulsive disorder(OCD) from a residential treatment program. It was hypothesized that the YBOCS-SR total score would be correlated to the total OBQ-44 score as well as to each of the three subscales of the OBQ-44; Responsibility/Threat Estimation, Perfectionism/Certainty, and Importance/Control of Thoughts. The results showed significant correlation in both YBOCS-SR and total OBQ-44 scores and YBOCS-SR and the subscales Responsibility/Threat Estimation and Perfectionism/Certainty. There was no significant relationship between the YBOCS-SR with the Importance/Control of thoughts subscale. These relationships indicate that the YBOCS-SR, which measures symptom severity, correlates to obsessional beliefs of someone with OCD as well as that obsessional beliefs about responsibility and threat estimation and perfectionism and certainty are related to symptom severity
