Purpose: To test the psychometric properties of the International Prostate Symptom Score (Hong Kong Chinese version 2) (IPSS) in Chinese male patients with benign prostatic hyperplasia (BPH) under secondary care. Methods: A prospective longitudinal study was done by interviewing subjects at baseline, at 2 week after baseline for assessing testâretest reliability and at 26 week after baseline for assessing responsiveness. All subjects were interviewed to complete a structured questionnaire including IPSS, Short Form-12 Health Survey version 2 (SF-12v2) and Depression Anxiety Stress Scale (DASS). Results: The IPSS HRQOL score had weak correlations with SF-12v2 summary and DASS domain scores. For reliability analysis, Cronbachâs alpha coefficient was 0.90 for the seven symptom-related items. The intraclass correlation coefficients of the IPSS total symptom score and HRQOL score were 0.90 and 0.86, respectively. For sensitivity, statistically significant differences were detected between the subjects with BPH and those without for IPSS total symptom score (effect size = 0.68) but not the IPSS HRQOL score. The areas under ROC curves for the IPSS total symptom and HRQOL scores were 0.67 and 0.60, respectively. Conclusions: The IPSS was valid, reliable instrument in Chinese patients with BPH. The IPSS total symptom score, but not the HRQOL score, is sensitive in differentiating subgroups.Link_to_subscribed_fulltex
