Aims To investigate the reliability and validity of the Turkish version of the Danish Prostate Symptom Score (Dan‐PSS) questionnaire in patients with Parkinson's disease (PD) and to compare the burden of LUTS (Lower urinary tract symptoms) in men and women. Methods For analysis of test‐retest reliability, the Turkish version of the Dan‐PSS scale was developed using the back translation method, and it was administered on the day of admission and repeated 1 week after in 60 patients with PD. The OAB‐q (Overactive Bladder Questionnaire) and PDQ‐39 (Parkinson's Disease Questionnaire‐39) were administered to 73 patients for validity analysis. Results Both the internal consistency (Cronbach's alpha coefficient: 0.99‐1.00) and the test‐retest reliability (intraclass correlation coefficient: 0.99‐1.00) of the Dan‐PSS were found to be high in patients with PD. Although weak to moderate correlations were found between the subscales of the Dan‐PSS and PDQ‐39 ( r : 0.20‐0.42; P < 0.05), a strong correlation was found with the OAB‐q ( r : 0.60‐0.79; P < 0.05). Nocturnal urination was the most frequent (93.2%), and bothersome (54.8%) symptom. The majority of the symptom and bother responses were similar in men and women. Conclusions Current study shows that the Turkish version of the Dan‐PSS questionnaire is an internally consistent, reliable, and valid scale for patients with PD. Therefore, it can be used to evaluate frequency and severity of LUTS in PD. LUTS are commonly seen in patients with PD in both sexes. It is suggested that all patients with PD should be referred for urological assessment.
