Objectives To validate in Spanish (Spain) a self‐administered questionnaire on the quality of life (QoL) specific to nocturia in an older adult male population. Material and Methods We analysed the Spanish version of the ICIQ‐Nqol questionnaire (provided by ICIQ who owns the copyright), which meets the translation criteria required by the validation protocol. The study included 69 male patients older than 60 years of age with 1 or more nocturia episodes. The participants completed the questionnaire on two occasions, along with other Spanish‐validated questionnaires that measure the QoL related to urinary symptoms. We analysed the internal reliability and consistency, reproducibility, convergent validity and discriminant validity. Results The study included 69 men, with a mean age of 70.64 years (range, 60‐87 years). Both the overall scale and the energy/sleep subscale met the minimum criteria for internal reliability and consistency. A good correlation has been demonstrated between the overall index of the ICIQ‐Nqol questionnaire and the other questionnaires included in the study. The reproducibility (test‐retest reliability) of both the overall scale and subscales of the ICIQ‐Nqol and the other questionnaires was demonstrated. Conclusions The ICIQ‐Nqol questionnaire has been shown to be an appropriate instrument for assessing the symptomatic intensity and impact on the QoL of patients with nocturia. This study confirms its validity for a Spanish‐speaking male population. Neurourol. Urodynam. 35:847–850, 2016 . © 2015 Wiley Periodicals, Inc.
