Higher scores are worse for all variables, except for perceived functional independence and cognitive function (higher = better) and frequency of social activities (higher = more social activities). This implies that more, for example, walking difficulties and less, for example, functional independence are associated with more ADL disability (positive and negative correlation coefficients, resp.); ADL = activities of daily living; UPDRS = Unified Parkinson’s Disease Rating Scale; n = 243–250, depending on missing data. |
