Objective: Personality affects an individual's ability to cope with the burden of chronic disease. However, the impact of personality on quality of life (QoL) in Parkinson's disease (PD) is not well characterized. The goal of this study is to determine the effect of personality on QoL in PD. Methods: The study included 92 patients with idiopathic PD from Baltimore-Washington area movement disorder neurology clinics. QoL was assessed using the 37-item Parkinson's disease Quality of Life Questionnaire (PDQL) total score, and the Neuroticism-Extraversion-Openness Inventory was used to determine personality traits. Results: Step-wise regression models examined the contribution of personality, depression, demographic, and PD variables on PDQL-assessed QoL. Neuroticism, conscientiousness, years of education, and depression explained 42% of the variance in the PDQL total score after adjusting for other disease variables. High neuroticism (β=-0.727, 95% confidence interval (CI) -1.125, -0.328, p
