Quality of life in obsessive-compulsive disorder: the role of mediating variables

This study examined the association of various clinical features of obsessive-compulsive disorder (OCD) with quality of life (QoL) in 102 adults with a principal diagnosis of OCD. Participants were assessed by trained clinicians using the Anxiety Disorders Interview Schedule 4th edition, the Yale-Brown Obsessive-Compulsive Scale, and an unstructured clinical interview. Subjects completed the MOS-36 Item Short Form Health Survey, and Beck Depression Inventory-II. Obsessive-compulsive symptom severity was negatively correlated with emotional health, social functioning and general health QoL. Depressive symptoms mediated the relationship between obsessive-compulsive symptom severity and emotional health, social functioning and general health QoL. Additionally, interference of obsessive-compulsive symptoms mediated the relationship between obsessive-compulsive symptom severity and emotional health, social functioning and general health QoL. Resistance against obsessive-compulsive symptoms mediated the relationship between obsessive-compulsive symptom severity and social functioning QoL. Diminished QoL is present in persons with OCD and is essential in understanding the complete clinical picture of OCD.
