Concept elicitation, cognitive, and prioritization interviews were performed with patients, literature reviews, and clinician interviews to create USSIM content. We describe outcomes following field-testing and assessment of measurement properties for the purpose of creating an outcome measure that is reproducible and able to detect change after treatment. METHODS: A sample of 238 men with urethral stricture was assessed across 9 TURNS centers from 2016- 2018. The USSIM was administered before and 3-9 months after urethroplasty, and it was administered two weeks apart for test-retest reliability. Cystoscopy confirmed urethral patency after surgery. Psychometric analyses included exploratory factor and item response theory analyses. Internal consistency, validity, and test-retest reliability were also analyzed. To assess validity, the USSIM was compared to the only existing stricture-specific outcome measure. RESULTS: Exploratory factor analyses identified an 8-item voiding-related scale and a 3-item sexual function scale. The voiding subscale was highly sensitive to change, t(228) = 23.01, p < .0001, mean reduction = 36.6 on a 0-100% scale (Figure 1). The sexual function subscale was also sensitive to change, t(159) = 5.76, p < .0001, mean reduction = 9.9 on a 0-100% scale (Figure 2). Empirical reliability was .82 and .70 for the voiding and sexual subscales, respectively. Validity coefficients for the voiding scale were rs>= .37 for other measures of voiding symptoms, ps < .0001. Test-retest ICC was .30 for voiding and .56 for sexual items. Following clinical review, the USSIM was reduced: 1 perceived quality-of-life item, 1 surgical outcome item, and 11 other items with urinary and sexual subscales. CONCLUSIONS: The USSIM was psychometrically strong with adequate measurement properties. The reduced version is now being validated for clinical use.
