“…The range for each symptom score was 0-5, with an overall possible score of 0-35. The summation of the symptom score provides a composite score which classifies the respondent as being asymptomatic (score 0), mild symptoms (score 1-7), moderate symptoms (8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19) or severe (20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35). The AUA overall QoL question was used to score overall satisfaction about current urinary symptoms from 1 to 6, with 1 being 'delighted' and 6 being 'terrible' [1].…”

Symptom Score and yearly GP attendance questions were completed by 862 subjects with no history of prostate cancer. RESULTSThere were no significant differences in LUTS among the ethnic groups ( P = 0.80) but symptom scores were positively correlated with age only for NZ Europeans ( P < 0.001, r = 0.179). Overall, NZ populations have a lower prevalence of LUTS than is evident for ethnic groups in other countries. Pacific Islanders attended the GP more often than both NZ Europeans and Maori. CONCLUSIONEthnic differences in age-related urinary symptoms and visits to the GP are important for informing culturally appropriate clinical practice and prostate health promotion with minority groups.

“…For the IPSS, scoring ranges from 0 (no symptoms) to 35 (maximal symptoms). LUTS severity was classified into three categories: mild (0-7), moderate (8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19) and severe (20-35) and for the QoL index, the range is 0 (delighted) to 6 (terrible) [16]. The storage subscore was defined as the sum of scores for questions 2, 4 and 7 on the IPSS and the voiding subscore was the sum of scores for questions 1, 3, 5 and 6.…”

Reliability and validity of the King’s Health Questionnaire for lower urinary tract symptoms in both genders

OBJECTIVE To investigate the reliability and validity of the King’s Health Questionnaire (KHQ) in both genders, which was originally developed as a health‐related quality of life (HRQoL) questionnaire for female urinary incontinence for general lower urinary tract symptoms (LUTS). SUBJECTS AND METHODS Data from the International Prostate Symptom Score (IPSS) and KHQ obtained from 179 men and 75 women consulting urologists (Sample A) were analysed. Cronbach’s α coefficient and inter‐domain correlation were calculated for reliability and validity assessment, respectively. Factor analysis was used to explore the underlying factor structure of the KHQ. KHQ scores of sample A were compared with those of 330 men and 418 women consulting general practitioners (Sample B). RESULTS Internal consistency of KHQ was acceptable with a Crohnbach’s α of 0.721–0.915 in the total population of sample A. Correlation analysis showed convergent validity among ‘Physical Limitations’, ‘Role Limitation’ and ‘Social Limitations’ and discriminant validity among ‘Personal Relationship’, ‘Emotion’s and ‘Sleep/Energy’. Factor analysis showed three underlying components to explain convergent and discriminant validity. In both sample A and sample B, HRQoL was impaired in the eight domains according to IPSS severity. KHQ scores of domains other than ‘General Health Perception’ in sample B were lower than those in sample A. CONCLUSION The KHQ can be used as a HRQoL questionnaire for LUTS in both genders. In the future, it is expected that the KHQ could be used in clinical studies for benign prostate hyperplasia and other conditions.

“…The core lower urinary tract symptom score (CLSS) questionnaire was recently developed by Dr Homma's group, 1 and had been used as a reliable instrument for lower urinary tract symptoms (LUTS) assessment in several studies. 2,3 However, the psychometric properties of the CLSS still need to be further evaluated.…”

“…[1][2][3][4][5][6] The ICI recommended the use of the ICIMaleSF questionnaire for men and ICIFemaleSF for women on assessing LUTS; however, they could contain too extensive or variable questions. [7][8][9] The CLSS questionnaire was reported by Homma et al in 2008.…”

Core lower urinary tract symptom score questionnaire: A psychometric analysis

Abbreviations & AcronymsObjectives: To analyze the reliability and validity of the Japanese version of the core lower urinary symptom score questionnaire with psychometric methods. Method: The present study included 140 women and 125 men who filled in a core lower urinary symptom score questionnaire while attending two lectures on lower urinary tract symptoms. Missing response rates to individual questions were 1.5-5.3%. After the descriptive analyses including box plot, Cronbach's α coefficients and Spearman's ρ were calculated for reliability and validity assessment, respectively. Factor analysis was also carried out to explore the underlying structure. Results: Of the scores for 10 core symptoms, the interquartile range for pain in the bladder and urethra was 0 in both sexes, and that for stress incontinence was 0 in men. Cronbach's α of the core lower urinary symptom score was 0.733 in women and 0.721 in men. Questions regarding daytime frequency, nocturia, urgency and urgency urinary incontinence, and those on slow stream, straining and feeling of incomplete emptying were significantly correlated with each other in both sexes. Pain in the urethra and bladder showed more extensive associations in women than in men. Factor analysis showed four components in both sexes: the first was storage symptoms, second was voiding symptoms, third was pain and the fourth was urinary incontinence. Conclusions: The core lower urinary symptom score questionnaire shows good reliability and validity for both sexes, and it could be used as screening tool for lower urinary tract symptoms in any clinical setting or epidemiological investigation.

Evaluation of Psychometric Properties of Japanese Version of International Prostate Symptom Score and BPH Impact Index

Abstract: Japanese translations of IPSS and BII were shown to be reliable, valid and one-dimensional instruments in the Japanese patients. They would be equivalent to the original English questionnaires.
