Chronic Prostatitis Symptom Index (CPSI):

A questionnaire developed in 1999 by physicians in NIDDK's Chronic Prostatitis Collaborative Research Network can help physicians to accurately measure the severity of prostatitis symptoms and their impact on a patient's lifestyle. The CPSI questionnaire assesses pain, urination, and the effect of chronic prostatitis on daily activities. With this information, researchers and physicians can reliably evaluate whether potential treatments are working. The questionnaire was originally published in the Journal of Urology in August 1999 (Vol. 162, pages 369-375). It is available as a PDF document in English, Spanish, German and Korean.
