Correlates of quality of life and functional disability in individuals with body dysmorphic disorder

Objective: Body dysmorphic disorder (BDD) is a chronic mental illness characterized by low quality of life and functional disability across multiple domains. Despite the clinical importance of understanding impairment in BDD, there has been little research examining the factors that contribute to these constructs. The present study was designed to examine sociodemographic and clinical correlates of quality of life and disability (work, social, and family) in a sample of individuals with moderately severe BDD symptoms.

Method: Participants completed an internet survey with questions about demographics, BDD phenomenology, treatment, and impairment. Only participants who completed all study measures and received a score≥16 on the 10-item Yale-Brown Obsessive Compulsive Scale, Modified for BDD (BDD-YBOCS), indicating the presence of clinical BDD symptoms, were included in the analysis (n=256). Multivariate regression with backwards variable selection was used to identify significant predictors of quality of life and functional disability, assessed with the Quality of Life Enjoyment and Satisfaction Scale-Short Form (QLESQ-SF) and the Sheehan Disability Scale (SDS), respectively.

Results: BDD symptom severity was inversely associated with quality of life and directly associated with disability in all domains. After controlling statistically for BDD symptom severity, sociodemographic and clinical factors such as age, gender, ethnicity, marital status, insurance, body parts of concern, depression symptoms, and anxiety symptoms were significantly associated with impairment.

Conclusion: Results suggest a multidimensional nature of quality of life and functional disability and underscore the importance of developing holistic treatment strategies to address impairment in BDD.
