Researchers from Oxford, UK, have developed and validated a patient-reported outcome measure—the Intermittent Self-Catheterization Questionnaire (ISC-Q)—for evaluating quality of life in patients with chronic retention who self-catheterize. ISC-Q validation, which involved 306 individuals with neurologic urinary retention, established that the test was psychometrically robust, with excellent internal consistency, adequate test-retest reliability, and good validity.
