Reliability and validity of King's Health Questionnaire in patients with symptoms of overactive bladder with urge incontinence in Japan

AIMS: The purpose of this study is to evaluate the psychometric properties of the Japanese version of the King's Health Questionnaire (KHQ) in patients with symptoms of overactive bladder (OAB) with urge incontinence. METHODS: Data from a 12-week, randomized, double-blind, placebo-controlled clinical trial comparing tolterodine with oxybutynin in patients with symptoms of OAB in Japan were analyzed. Cronbach's alpha coefficient was calculated as a reliability index. Inter-domain correlation was calculated for convergent and discriminant validity assessment. A factor analysis was conducted to explore the underlying factor structure of the KHQ. Sensitivity to clinical change was also evaluated. RESULTS: The psychometric properties and clinical validity of the KHQ Japanese version were confirmed in this study population, and were similar between males and females. The KHQ's good reliability was evidenced by Cronbach's alpha coefficients of >0.60, indicating reasonable consistency except for the personal relationship domain in males (0.47) and severity (coping) measure domain in females (0.59). Discriminant, convergent, and construct validity of the KHQ were also good, with the factor analysis identifying those factors which the KHQ was intended to measure. Finally, KHQ domains were generally responsive to clinical efficacy variables; the KHQ also showed statistically significant sensitivity to change in patients' perception of bladder condition in all domains, except General Health Perception. CONCLUSIONS: Our analyses confirm psychometric properties and clinical validity of the KHQ Japanese version, which appears to offer a valid and reliable HRQoL instrument for use in clinical trials of antimuscarinics in Japan.     

Psychometric properties and validation of the German-language King's Health Questionnaire in women with stress urinary incontinence

AIMS: The purpose of this study was to evaluate the psychometric properties of and validate the German-language version of the King's Health Questionnaire (KHQ) in women with stress urinary incontinence (SUI). METHODS: A total of 145 women treated for stress incontinence with surgery or physiotherapy completed the the KHQ and the SF-36 before and after treatment. Psychometric analyses of the quality of life (QoL) instruments determined the reliability (Cronbach's alpha), internal and external validity, and responsiveness of the KHQ subscales. RESULTS: The KHQ showed good internal consistency, content validity, and criterion validity as measured by correlation with scores on the SF-36. Cronbach's alpha coefficient ranged from 0.76 to 0.86, indicating a high internal consistency of the subscales. Concerning criterion validity, correlations between the KHQ subscales and the SF-36 were low to moderate. The highest correlation was found between the general health perception subscales of both questionnaires. CONCLUSIONS: The results indicate good psychometric properties for the German-language KHQ.     

Validation of the Danish version of the musculoskeletal tumour society score questionnaire

BACKGROUND The musculoskeletal tumour society score(MSTS) is a well-known questionnaire for measuring functional outcome in patients with neoplasms in the extremities.Standardized guidelines for cross-cultural translation and validation ensure the equivalence of content between the original and translated versions. The translation and validation provide the possibility to compare different sarcoma populations on an international level. This study is based on the hypothesis that the Danish MSTS questionnaire is a valid tool for measuring the end result after surgery for neoplasms in the extremities.AIM To validate the Danish version of the upper and lower extremity version of the MSTS.METHODS The translation of the MSTS was conducted in accordance with international guidelines. Patients operated for sarcomas and aggressive benign tumors were invited to participate in the study. The psychometric properties of the Danish version of the MSTS were tested in terms of validity and reliability and for the risk of floor or ceiling effect. Spearman's rank coefficient was used to test the validity by comparing with the Toronto Extremity Salvage Score(TESS). The Intraclass Correlation Coefficient(ICC) was used to evaluate inter-rater reliability. Cronbach's alpha was used to test for internal consistency. Spearman's rank coefficient was used to compare the MSTS lower extremity version with the objective test, Timed Up and Go(TUG).RESULTS The upper extremity version demonstrated an ICC of 0.95 in the inter-rater reliability test. The lower extremity version had an ICC of 0.88 in the inter-rater reliability test, respectively. Both MSTS versions showed a ceiling effect. Thevalidity of the MSTS was measured by Spearman's rank correlation coefficient by comparing the MSTS with the TESS and found it to be of 0.80(P 0.01) and 0.83(P 0.01) for the upper extremity and lower extremity version, respectively. A Spearman's rank correlation coefficient of-0.26(P 0.01) was found between the TUG and the MSTS questionnaire. A Spearman's rank correlation coefficient of-0.38(P 0.01) was found between the TUG and the lower extremity version of the TESS questionnaire.CONCLUSION The Danish version of the MSTS questionnaires were found to have good reliability and validity, however a substantial ceiling effect was identified.     

Reliabilität und Veränderungssensitivität der deutschen Version des Fragebogens Arm, Schulter und Hand (DASH)

BACKGROUND: Whilst there are some studies which have focussed on the validity and also others partially on the reliability of the German version of the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH), studies regarding test-retest reliability and responsiveness do not exist. The purpose of this study was to analyse these two meaningful properties of the officially approved German version of the DASH. METHODS: Of 101 consecutive patients with distal radius fractures, 72 were followed prospectively at three time intervals. To evaluate the reliability, internal consistency (Cronbach's alpha) and correlation between the DASH points from the 12- and 13-week examinations (Spearman's correlation coefficient and intra-class coefficient) were calculated. Responsiveness was assessed using the parameters change score, standardised effect size and standardised response mean. These values were compared with the same values obtained from the traditional measures of grip strength and range of motion. RESULTS: Internal consistency and test-retest reliability of the DASH were excellent (Cronbach's alpha >0.95, Spearman's correlation coefficient r=0.912, ICC=0.945). Responsiveness of the DASH was moderate (change score=8.93, SRM=0.55, SES=0.41). Responsiveness of the ROM deficit and grip strength were larger than that for data from the DASH. CONCLUSION: The German DASH is a reliable and responsive measure. It can detect changes in disabilities over time in patients with distal radius fractures. Traditional impairment measures reflect important functional aspects and should be included in clinical outcome evaluation.

Cross-cultural adaptation and validation of the French version of the Knee injury and Osteoarthritis Outcome Score (KOOS) in knee osteoarthritis patients

OBJECTIVE: To adapt the Knee injury and Osteoarthritis Outcome Score (KOOS) into French and to evaluate the psychometric properties of this new version. METHODS: The French version of the KOOS was developed according to cross-cultural guidelines by using the "translation-back translation" method to ensure content validity. KOOS data were then obtained in patients with symptomatic knee osteoarthritis (OA). The translated questionnaire was evaluated in two knee OA population groups, one with no indication for joint replacement (medicine), and the other waiting for joint replacement (surgery). The psychometric properties evaluated were feasibility: percentage of responses, floor and ceiling effects; construct validity: internal consistency using Cronbach's alpha, correlations with osteoarthritis knee and hip quality of life domains using Spearman's rank test, and known group comparison between medicine and surgery groups; reliability: intra-class correlation coefficient (ICC), Bland and Altman representation; responsiveness using data obtained prior to and 3 months after surgery: standardized response mean (SRM), and effect size. RESULTS: Thirty-seven patients were included in the medicine group (68% women, mean age=70+/-10 years) and 30 in the surgery group (73% women, mean age=71+/-10 years). The percentage of responses was excellent. Neither a floor nor a ceiling effect was observed, except for the sport and recreation subscale (20.6% of patients with the worst possible score in the medicine group, 40 and 0% in the surgery group prior to and after surgery, respectively). Results for internal consistency (Cronbach's alpha ranging from 0.76 to 0.93), and convergent and divergent construct validity were satisfactory. The patients waiting for knee surgery presented with significantly lower scores in all KOOS domains. The reproducibility of measurements of all KOOS subscales was good to excellent, with ICC ranging from 0.755 to 0.914. The responsiveness was high, with SRM ranging from 0.89 to 1.93, and effect size from 1.31 to 2.8. CONCLUSION: The French version of KOOS is a valid, reliable, and responsive instrument to capture specific aspects of functional disability affecting quality of life of knee OA patients.     

Cross-cultural adaptation and validation of Singapore English and Chinese versions of the Knee injury and Osteoarthritis Outcome Score (KOOS) in Asians with knee osteoarthritis in Singapore

OBJECTIVE: To cross-culturally adapt and validate Singapore English and Chinese versions of the Knee injury and Osteoarthritis Outcome Score (KOOS) in patients with knee osteoarthritis (OA) in Singapore. METHODS: Singapore English and Chinese versions were cross-culturally adapted from the source English KOOS following standard guidelines (including cognitive debriefing). Patients were asked to complete identical questionnaires containing the KOOS, Short Form 36 Health Survey, and EQ-5D twice within 6 days. Reliability was assessed using Cronbach's alpha and intraclass correlation coefficients (ICC), dimensionality using item-to-domain correlations and convergent and divergent construct validity using 14 and 13 a priori hypotheses, respectively. RESULTS: Singapore English and Chinese KOOS versions were well accepted by patients in pilot testing and were therefore administered to a consecutive sample of 127 English and 131 Chinese-speaking Singaporeans with knee OA. Cronbach's alpha exceeded 0.7 for all domains except for Chinese pain and symptoms domains. ICC exceeded 0.7 for all domains except for English sport and recreation and Chinese knee-related QoL domains. Hypothesized item-to-domain correlations (Spearman's rho>or=0.4) were observed for 38 items in English and 29 in Chinese versions. Convergent construct validity was supported by the presence of hypothesized moderate/strong correlations (rho=0.37-0.65) for 13 and 11 a priori hypotheses in the English and Chinese KOOS, respectively. Divergent construct validity was supported by the presence of weak correlations (rho=0.02-0.34) for 12 and 11 a priori hypotheses in the English and Chinese KOOS, respectively. CONCLUSION: The Singapore English and Chinese KOOS were well accepted and demonstrated acceptable reliability and validity in Asian patients with knee OA in Singapore.     

Reliability and validity of the Malay version of the International Index of Erectile Function (IIEF-15) in the Malaysian population

The objective of this study was to validate the Malay version of the International Index of Erectile Function (IIEF-15) in patients with lower urinary tract symptoms. Reliability and validity was assessed by using the test-retest while Cronbach's alpha was used to assess internal consistency. Effect size 5was evaluated to assess the sensitivity to change in the pre-transurethral resection of the prostate (TURP) vs post-TURP. Internal consistency was excellent. A high degree of internal consistency was observed for each of the 15 items and five domains (Cronbach's alpha value=0.56 and higher and 0.74 and higher, respectively). Test-retest correlation coefficient for the 15 items and domains scores showed no significant changes. Intraclass correlation coefficient for 15 items and domains were high (ICC=0.59 and above). It can be concluded that the Mal-IIEF-15 is suitable, reliable, valid and sensitive to clinical change in the Malaysian population.     

Test-retest reliability of four questionnaires for patients with overactive bladder: the overactive bladder questionnaire (OAB-q), patient perception of bladder condition (PPBC), urgency questionnaire (UQ), and the primary OAB symptom questionnaire (POSQ)

AIMS: This study examined test-retest reliability of four patient-reported outcome measures for patients with overactive bladder (OAB): Overactive Bladder Questionnaire (OAB-q), Patient Perception of Bladder Condition (PPBC), Urgency Questionnaire (UQ), and Primary OAB Symptom Questionnaire (POSQ). METHODS: Patients recruited from urology clinics were scheduled for two visits 2 weeks apart and completed all questionnaires at both visits. A demographic form was completed at Visit 1; and a treatment effect scale was completed at Visit 2. Test-retest reliability was examined among stable patients using intraclass correlations (ICC), Spearman's correlations, paired t-tests, Feldt's statistic, and kappas. RESULTS: A total of 47 patients enrolled (mean age = 66.0 years, 74.5% female), with 46 completing both visits; 35 were classified stable. Statistically significant correlations were present between Visits 1 and 2 (P < 0.05) for all subscales of the OAB-q, UQ, and POSQ. Subscale ICCs were moderate to high (OAB-q > or = 0.83, UQ > or = 0.46, POSQ continuous items > or = 0.68). No significant differences between Visit 1 and 2 were noted, except for the OAB-q symptom bother scale (change of 5.8 points on a 100-point scale). The multi-item subscales of the OAB-q and the UQ demonstrated good internal consistency (Cronbach's alpha > or = 0.83 for all subscales) across both visits. Test-retest reliability of the PPBC was somewhat weaker than the other three measures, but still acceptable for use as a global, single-item outcome measure. CONCLUSIONS: The OAB-q, POSQ, and UQ demonstrated good test-retest reliability, with ICCs roughly equivalent or superior to those previously reported for 7-day micturition diaries. Findings suggest that the four measures examined in this study demonstrate the necessary reproducibility for use as outcome measures for OAB treatments.     

Psychometric validation of the Japanese version of the International Consultation on Incontinence Questionnaire-Short Form

Objective:   To evaluate the psychometric properties of the Japanese version of the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF).
Methods:   Two study samples of 180 patients with urinary incontinence were used for this psychometric evaluation. Analyses were carried out to examine the instrument's reliability and validity, as well as its responsiveness to change.
Results:   For the ICIQ-SF items and total scores, there was no particular floor or ceiling effect. The internal consistency was sufficiently high, with a Cronbach's alpha coefficient of 0.78. In the analysis of test-retest reliability, high correlations were observed, with Kappa coefficients of 0.61 for item 1 and 0.62 for item 2, and with intra-class correlation coefficients of 0.90 for item 3 and 0.91 for the total score. For the concurrent validity, the ICIQ-SF scores were moderately to highly correlated with most of the King's Health Questionnaire (KHQ) subscales. When the severity groups, divided in quartiles, were compared with respect to the 1-h pad test and the number of daily incontinence episodes, there seemed to be linear trends in most of the ICIQ-SF scores. For responsiveness, changes in the ICIQ-SF after treatment demonstrated statistically significant correlations of more than 0.5 with changes in some of the KHQ subscale scores. All of the ICIQ-SF items and total scores significantly decreased after treatment.
Conclusions:   The Japanese version of the ICIQ-SF is a reliable, valid and responsive measure that performs well among patients with urinary incontinence.
