BACKGROUND: Both motor and non-motor symptoms could contribute to significant deterioration of psychological well-being in patients with Parkinson's disease (PD). However, its assessment has been only indirectly evaluated using tools based on health-related quality of life (HRQoL), such as the PDQ-39 scale. OBJECTIVES: To evaluate psychological well-being in PD using a specific tool of assessment, the Psychological Well-being Scale (PWS), and its clinical correlates. METHODS: This article reports data of patients' perception of health state, as measured by means of the PWS, from an epidemiological, cross-sectional studyconducted in Italian PD patients (FORTE Study). We tested possible relationship between well-being and clinical characteristics including fatigue, depression, sleep disruption and HRQoL. RESULTS: 272 patients completed the PWS questionnaire. Significant and clinically-relevant correlations were found between PWS total score and Parkinson's Fatigue Scale, Beck Depression Inventory, UPDRS Section I, PD Sleep Scale and PDQ-39 for HRQoL scores. Only clinically negligible correlations were found between PWS and motor scores. CONCLUSIONS: Non-motor symptoms have a significant impact on psychological well-being in PD patients.
