The EORTC QLQ-PR25 employs a modular approach towards assessing cancer patients´ health-related Quality of Life (QoL) and assesses urinary, bowel, and sexual symptoms and functioning, and the side-effects of hormonal treatment. It consists of 25 questions distributed on six domains (number of items per domain, ranges from x to y: urinary symptoms (8, 0-100), bother due to use of incontinence aid (1, 0-100), bowel symptoms (4, 0-100), hormonal treatment-related symptoms (6, 0-100), sexual activity (2, 0-100), and sexual functioning (4, 0-100). All raw domain scores are linearly transformed to a 0-100 scale, with higher scores reflecting either more symptoms (urinary, bowel, hormonal treatment-related symptoms) or higher levels of activity or functioning (sexual).
