Purpose Qualiveen‐30 is a neurological urinary disorder (UD)‐specific health‐related quality of life (HRQL) instrument, recommended in the European Association of Urology guideline 2008. The objective is to complete the cultural adaptation of Qualiveen‐30 into Italian. Materials and Methods One hundred and twenty eight Italian‐speaking spinal cord injury (SCI) patients completed Qualiveen‐30 and the SF‐12 physical and mental component (PC and MC) at enrolment and 4 weeks later. At follow‐up, patients also made global ratings of change (GRC) in urinary HRQL (GRC). Results Qualiveen‐30 proved reliable (intraclass correlation coefficients of four domains: 0.77–0.90). Correlations with SF‐12 and GRC were generally consistent with our a priori predictions. Qualiveen‐30 domains showed weak‐to‐moderate cross‐sectional correlations with SF‐12 scores (0.31–0.45 PC and 0.28–0.45 MC). Correlations between changes in Qualiveen‐30 scores and in SF‐12‐PC scores were weak or absent. Correlations between changes in Qualiveen‐30 scores and in SF‐12‐MC scores were weak to moderate (0.25–0.38). Relationships between change in Qualiveen‐30 and GRC were moderate to strong (0.48–0.56). The responsiveness was excellent, similar to the original form (SMR: 1.76–2.31). Minimally important difference values in the four domains varied from 0.34 to 0.47. Conclusions Italian Qualiveen‐30 is a reliable, valid, and responsive measure of UD‐related HRQL in SPI patients. Investigators can be confident of the Qualiveen‐30 questionnaire's ability in distinguishing between patients in a cross‐sectional survey, as well as in measuring within‐subject changes over time in clinical trials in French, English, and Italian.
