Severity scales
SCOPA – AUT11	140 PD patients and 100 controls	6 (both filling and voiding phase)
NMSS12	242 PD patients multinational	3 (only relating to urgency, frequency and nocturia)
COMPASS13*	41controls, 33 patients with non‐autonomic peripheral neuropathy, 39 patients with autonomic failure (9 PAF, 4 PK plus, 2 MSA)	3

Questionnaire on Bladder and autonomic dysfunction in PD18	sample of patients with PD (n = 123) and elderly controls without PD (n = 92)	9 (both filling and voiding phases) based also on Berrios' et al scale + 2 items on QoL related to bladder dysfunction
Screening tools
