  • exploration of influencing factors (PD status, therapeutic status) on the prevalence of MDI depression categories.

Primary Outcome Measures :
  1. Prevalence of patients with depressive symptoms (based on WHO-5 and MDI) in total and in subgroups [ Time Frame: day 1 ]

Secondary Outcome Measures :
  1. WHO-5 score and items [ Time Frame: day 1 ]
  2. MDI score (for a subgroup of patients with WHO-5 score < 13 or any WHO-5 item rated with 0 or 1) [ Time Frame: day 1 ]
  3. Correlation of WHO-5 and MDI (for a subgroup of patients with a WHO-5 score < 13 or any WHO-5 item rated with 0 or 1) in PD patients [ Time Frame: day 1 ]
  4. Investigator assessment of the applicability of the WHO-5 for screening for depression in PD patients [ Time Frame: day 1 ]
