To analyze the reliability and validity of the WHODAS 2.0 instrument for women with urinary incontinence (UI). This is a methodological study with Brazilian women with complaints of urge, stress or mixed UI, over 18 years old, without cognitive disorders. The WHODAS 2.0 (36-item version) and the auxiliary instruments were applied through face-to-face and telephone interviews after 7-14 d. The psychometric properties evaluated were: Cronbach's alpha for internal consistency, intraclass correlation coefficient (ICC) for intra-rater test-retest, Spearman's correlation coefficient (rho) for construct validity of WHODAS 2.0 with auxiliary instruments; and ANOVA for discriminative validity with UI severity. 101 women with UI with a mean age of 50.71 ± 10.39 were included. WHODAS 2.0 showed good reliability in all domains and excellent reliability in the total score (>0.80). The intra-evaluator test-retest showed ICC values between 0.59 and 0.87 (
