Abstract Background In 2003 a 74-item quality-of-life QOL scale for Chinese benign prostatic hyperplasia BPH patients BPH-QLS was developed. Although the scale displayed good reliability and validity the time required to complete it may limit its use. The purpose of this study was to construct and validate a short-form quality-of-life QOL scale for Chinese patients with Benign Prostatic Hyperplasia BPH . Methods According to the previously published 74-item quality of life scale for BPH BPH-QLS we developed a pool of items then condensed these items and validated the shortened scale based on collected data from 163 patients with BPH. We used eight methods to reduce the items. Results A 33-item QOL scale for BPH short-form of BPH-QLS was constructed. The time take by the new scale was much shorter than the original one. There was no significant difference between the 33-item scale and .
