Question 1

What does the NIH-CPSI measure?

Accepted Answer

The NIH-CPSI measures the severity and impact of chronic prostatitis / chronic pelvic pain syndrome (CP/CPPS) in men across three areas: pain or discomfort, urinary symptoms, and quality of life. It is the most widely used outcome measure for this condition.

Question 2

How is the NIH-CPSI scored?

Accepted Answer

The questionnaire produces three subscale scores - Pain (0-21), Urinary symptoms (0-10), and Quality of life (0-12) - which sum to a total score from 0 to 43. A total of 0-14 indicates mild symptoms, 15-29 moderate, and 30-43 severe. Higher scores mean greater symptom burden.

Question 3

Is this the same as a prostate cancer test?

Accepted Answer

No. The NIH-CPSI measures symptoms of prostatitis and pelvic pain, not cancer. It cannot diagnose or rule out prostate cancer, infection, or other conditions. A healthcare provider uses it alongside examination and other tests.

Question 4

How often should I complete the NIH-CPSI?

Accepted Answer

It is typically completed at baseline and then at follow-up intervals to measure how symptoms change with treatment. For pelvic treatment programs it can be repeated periodically to track progress. Your provider will advise on timing.
