MATERIALS AND METHODS: Validity and reliability were studied in patients with and without lower urinary tract symptoms. Reliability was evaluated using the test-retest method and internal consistency was assessed by Cronbach's alpha. Sensitivity to change was expressed as the effect size in the pre-intervention versus post-intervention score in additional patients with lower urinary tract symptoms who underwent transurethral prostate resection.
RESULTS: Internal consistency was excellent. A high degree of internal consistency was observed for each of the 7 items and for the total score (Cronbach's alpha 0.53 and greater, and 0.68, respectively). The test-retest correlation coefficients of the 7 items were highly significant. The intraclass correlation coefficient was high at 0.51 and greater. There was a high degree of sensitivity and specificity to the effects of treatment. Significant change from baseline to posttreatment scores was observed in all 8 items in the treated but not in the control group.
CONCLUSIONS: The Malay International Prostate Symptom Score is a suitable, reliable, valid instrument that is sensitive to clinical change in the Malaysian population.
PATIENTS AND METHODS: Validity and reliability were assessed in patients with lower urinary tract symptoms (LUTS) and in patients with no LUTS. Reliability was evaluated using the test-retest method and internal consistency using Cronbach's alpha. Sensitivity to change was expressed as the effect size in the score before and after intervention in additional patients with LUTS who underwent transurethral resection of the prostate (TURP).
RESULTS: Internal consistency was excellent; there was a high degree of internal consistency for each of the seven domains and for the total score (Cronbach's alpha > or = 0.60 and > or = 0.79, respectively) in the populations studied. The test-retest correlation coefficient for the seven domain scores was highly significant. The intra-class correlation coefficient was high (> or = 0.59). There was a high level of sensitivity and specificity for the effects of treatment, with a very significant change between the seven scores domains in the treated group but not in the control group.
CONCLUSIONS: The IPSS is suitable, reliable, valid and sensitive to clinical change in the Malaysian population.
PATIENTS AND METHODS: The study included 123 patients (mean age 64.6 years, SD 7. 95) with LUTS who were treated medically (with alpha-blockers, i.e. terazosin, prazosin, doxazosin and alfuzosin), and 52 patients (mean age 69.6 years, SD 7.94) with LUTS and confirmed to have benign prostatic hyperplasia (BPH) who underwent transurethral resection of the prostate (TURP). Both groups were assessed at baseline and 3 months after treatment using standardized questionnaires (the Beck Depression Inventory, the State-Trait Anxiety Inventory and the General Health Questionnaire-12).
RESULTS: Patients before TURP were significantly more depressed, worried and psychiatrically morbid than were those before medical treatment. Three months after medical and surgical treatment, there was significantly less depression, anxiety and psychiatric morbidity in the TURP than in the medication group.
CONCLUSIONS: TURP is a better treatment than medication for minimising anxiety, depression and psychiatric morbidity after treatment in patients with LUTS, but causes greater psychological stress before treatment.
