Objective – To determine the content and face validity of the Danish Prostate Symptom Score (DAN‐PSS‐1) questionnaire in stroke patients. Materials and methods – Content validity was judged among an expert panel in neuro‐urology. The judgement was measured by the content validity index (CVI). Face validity was indicated in a clinical sample of 482 stroke patients in a hospital‐based, cross‐sectional survey. Results – I‐CVI was rated >0.78 (range 0.94–1.00) for 75% of symptom and bother items corresponding to adequate content validity. The expert panel rated the entire DAN‐PSS‐1 questionnaire highly relevant (S‐CVI = 1.00). No experts suggested items omitted or improved. The response rate was 84% and face validity had an acceptable level of completed response for each symptom items (96–98%) and bother items (93–96%) indicating that all items were well interpreted. Conclusion – The DAN‐PSS‐1 questionnaire appears to be content and face valid for measuring lower urinary tract symptoms after stroke.
