Short Description of Instrument
The International Prostate Symptom Scale (IPSS) has become the international standard questionnaire used for assessing lower urinary tract symptoms in men but it is also valid and reliable for women as well.
The IPSS is essentially the AUA-7 scale (American Urological Association -7, developed by the American Urological Association in 1992) plus an eighth question on quality of life (QOL).
The IPSS is scored from 0-35, with higher scores indicating more and more severe symptoms. Nocturia is scored from 0 to 5 (five or more times per night) as the actual voiding frequency per night.
Other symptoms are scored on a frequency scale from 0 to 5: 0 (not at all); 1 (less than once every five times); 2 (less than half the time); 3 (about half the time); 4 (more than half the time); and 5 (almost always). The scores for each item are summed.
