≈ = Some evidence of validation but further evaluation required

The questionnaires/scales listed in this table on bladder dysfunction have been fully validated for urological disorders such as benign prostatic hyperplasia and incontinence and then used in PD patients. This table shows the clinimetric properties of the questionnaires/scales in these urological conditions not in PD patients (no data available except for DAN‐PSS;55 see corresponding column and text).
