Answer

The National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) covers the three most important domains of chronic prostatitis with nine questions. The first domain, pain, is captured in four questions covering location, severity, and frequency. The second domain, urinary function, is captured in two questions covering irritative storage symptoms and obstructive voiding function. The third domain, quality of life, is captured in three questions covering how the symptoms effect daily activities. The NIH-CPSI is pictured below.
