Validity of the Danish Prostate Symptom Score questionnaire in stroke.
OBJECTIVE
To determine the content and face validity of the Danish Prostate Symptom Score (DAN-PSS-1) questionnaire in stroke patients.


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.


CONCLUSIONS
The DAN-PSS-1 questionnaire appears to be content and face valid for measuring lower urinary tract symptoms after stroke.
