Popis: Aims To develop and assess structure, test–retest reliability, and discriminative validity of a self-report questionnaire (University of South Australia Urinary Sensation Assessment: USA2) to assess multiple dimensions of urgency sensation. Methods The USA2 was designed and tested over two prospective, observational studies (2013–2014). Participants were English speaking Australians aged 50 or more with and without overactive bladder (OAB; determined by OAB awareness tool), recruited via health and recreation centers. In Study 1, exploratory factor analysis determined USA2 structure and subscales. In Study 2, confirmatory factor analysis reassessed structure; Mann–Whitney U-tests determined discriminative validity (OAB vs. non-OAB for subscale and total scores) with Cohen's d effect sizes. Thirty-three individuals completed the USA2 twice; intraclass correlation coefficients (ICCs) and Wilcoxon signed rank tests assessed test–retest reliability. Results Questionnaires were returned by 189 eligible participants in Study 1 and 211 in Study 2. Exploratory factor analysis revealed three subscales: “urgency,” “affective,” “fullness.” Confirmatory factor analysis supported these subscales. Subscale and total scores were significantly different between groups with and without OAB (P
