- Values were obtained using multiple linear regression analysis with backward selection to identify predictors of HRQoL. Dependent variable: PDQ-39 summary index. Independent variables: Age, sex, BDI II, MDS-UPDRS part III, NMS-Q, MMSE, and GAS. BDI II: Revised version of Beck Depression Inventory; GAS: German version of the Geriatric Anxiety Scale; MDS-UPDRS III: Movement Disorder Society-sponsored revision of the Unified Parkinson’s Disease Rating Scale part III; MMSE: Mini-Mental State Examination; NMS-Q: Non-Motor Symptoms Questionnaire, PDQ-39: Parkinson’s Disease Questionnaire 39. B: Unstandardized regression coefficient. ß: Standardized regression coefficient. CI lb: Lower bound of the confidence interval. CI ub: upper bound of the confidence interval. Significance is indicated by *p <.05
