| Abstract | Objectives: To test the psychometric properties of a Maltese version of the IPSS score and compare the outcome with the psychometric properties of the original American score. Methods: A prospective observational study was conducted at the Urology Outpatient's Department., St Luke's Hospital in 50 patients with Benign Prostatic Hyperplasia (BPH) (age >50 years) and 60 control subjects (age 18 to 49 years) in order to test the validity and reliability of the IPSS-Mlt. Eligible subjects were given the translated version of the Maltese IPSS at the outpatients clinic and then where asked to submit another questionnaire one week after the initial one. Results: Construct Validity was assessed by correlating the IPSS-Mlt. scores with the QOL question in the IPSS and another global question on bother with Urinary symptoms. Discriminatory Power was assessed by calculating the area under the receiver operating curve (ROC). Reliability was evaluated using the test-retest method and checking for Internal Consistency reliability was done using Cronbach's alpha coefficient. Sensitivity to change was calculated as the effect size in pre-TURP vs. post- TURP scores in a subset of patients undergoing TURP. Discussion: The validation of a Maltese version of the IPSS is a necessary exercise in the standardisation of care of patients with LUTS. |
