Predictors of quality of life and functional impairment in obsessive-compulsive disorder

Abstract

Obsessive-compulsive disorder (OCD) is the 10th leading cause of disability among health conditions; yet, relatively little research has focused on quality of life (QOL) and functional impairment in OCD. The present study extended existing work by examining correlates and predictors of QOL and functional impairment in 96 treatment-seeking OCD patients (in intensive outpatient and residential settings). In a model including OCD symptoms and related phenomena, and symptoms of depression and anxiety, two main findings emerged: (a) depressive symptoms predicted both QOL and functional impairment, and (b) contamination symptoms predicted functional impairment. These findings are discussed in terms of the implications for studying QOL and functional impairment in OCD. Future research should investigate the factors that predict changes in QOL and functional impairment following treatment.
