THE NATIONAL INSTITUTES OF HEALTH CHRONIC PROSTATITIS SYMPTOM INDEX: DEVELOPMENT AND VALIDATION OF A NEW OUTCOME MEASURE

The National Institutes of Health chronic prostatitis symptom index provides a valid outcome measure for men with chronic prostatitis. The index is psychometrically robust, easily self-administered and highly discriminative. It was formally developed and psychometrically validated, and may be useful in clinical practice as well as research protocols.
