Targeting the Aetiology of Nocturia to Guide Outcomes (TANGO) is a validated English language questionnaire to identify underlying factors leading to nocturia. We set out to provide a culturally correct Arabic version of the TANGO questionnaire in Saudi Arabia. Methods: The English version underwent forwarded and backward translation. The final version was administered to native Arabic speaking hospital employees and patients. Test-retest reliability and the clarity of questions were determined by Kappa and Cronbach's α statistics. Results: The translation: The median Likert score for translated questions was ≥4 with a Cronbach's α .865. Test-retest reliability: Thirty employees answered the questionnaire. The median, standard deviation (SD), and range were age 29.0 ± 11.0 years (20-55), and nocturia 1.0 ± 0.96 episodes per night (0-4). Three questions had identical constant answers and no Kappa values were computed. Based on prevalence-adjusted bias-adjusted Kappa (PABAK) values, 10 questions had a "very good" agreement, eight questions had a "good" agreement, and one item had a "moderate" agreement. The range of PABAK was 0.53 to 1, P < .01. Clarity of questions: The employees had a median Likert score of 5.0 with a Cronbach's α .961. Thirty-two patients answered the questionnaire. The median, SD, and range were age 40.0 ± 15.4 years (17-79), and nocturia 1.0 ± 1.6 episodes per night (0-6). The median item score on the Likert scale was 5.0, with a Cronbach's α .909. A total of 29 (90.6%) patients stated that the questions were clear or needed no help to fill in the questionnaire. Conclusion: The Arabic language translation of TANGO questionnaire is a valid tool in the dialect of Saudi Arabia.
