Reliability, validity, and responsiveness of the Japanese version of the Patient-Rated Wrist Evaluation

BackgroundThe Patient-Rated Wrist Evaluation is a regionspecific, self-administered questionnaire consisting of a pain scale (PRWE-P) and a functional scale (PRWE-F), with the latter consisting of specific function (PRWE-SF) and usual function (PRWE-UF). The PRWE was cross-culturally adapted from the original English version by the Impairment Evaluation Committee, Japanese Society for Surgery of the Hand (JSSH). The purpose of this study was to test the reliability, validity, and responsiveness of the Japanese version of PRWE (PRWE-J).MethodsA consecutive series of 117 patients with wrist disorders completed the PRWE-J, the JSSH version of the Disabilities of the Arm, Shoulder, and Hand (DASH-JSSH) questionnaire and the 36-Item Short-Form Health Survey (SF-36). Of the 117 patients, 71 were reassessed for test-retest reliability 1 or 2 weeks later. Reliability was investigated by reproducibility and internal consistency. To analyze the validity, a factor analysis (principal axis factoring) of PRWE-J and correlation coefficients between PRWE-J and DASH-JSSH were obtained. Responsiveness was examined by calculating the standardized response mean (SRM) (mean change/SD) and effect size (mean change/SD of baseline value) after open surgery in 50 patients.ResultsCronbach’s α coefficients for PRWE-P, PRWE-F, and PRWE were 0.90, 0.95, and 0.95, respectively. The intraclass correlation coefficients (ICCs) for the same were 0.86, 0.93, and 0.92, respectively. Unidimensionality of PRWE-P was confirmed. Bidimensionality of PRWE-F was confirmed and separated clearly into PRWE-SF and PRWE-UF. The correlation coefficients between PRWE-P and PRWE-F or DASH-JSSH were 0.63 or 0.63, respectively. The correlation coefficient between PRWE-F and DASH-JSSH was 0.80. The correlation coefficients between DASH-JSSH and PRWE-SF or PRWE-UF were 0.76 or 0.73, respectively. Moderate correlation was observed in “physical functioning” for SF-36 and PRWE-SF (r = ?0.46), PRWE-F (r = ?0.46), or PRWE (r = ?0.46). The SRMs/effect sizes of PRWE-P, PRWE-F, or PRWE were respectively excellent: 1.7/2.2, 1.2/1.3, 1.6/1.9.ConclusionsThe PRWE-J has evaluation capacities equivalent to those of the original PRWE.     

Reliability,validity, and responsiveness of the Japanese version of the Neck Pain and Disability Scale

Background  

Until recently, no Japanese versions have existed of the more popular, patient-reported disability questionnaires for neck pain. This study aimed to test the reliability, validity, and responsiveness of the Japanese version of the Neck Pain and Disability Scale (NPDS), one of the most widely used questionnaires in patients with neck pain.     

Exploring the validation of a Japanese version of the International Hip Outcome Tool 12: Reliability,validity, and responsiveness

BackgroundsThe International Hip Outcome Tool 12 (iHOT12) was authorized by the Multicenter Arthroscopy of the Hip Outcomes Research Network (MAHORN). iHOT12 is increasingly being adopted in orthopedic studies to report patient outcomes. This study aimed to develop a Japanese version of the International Hip Outcome Tools “iHOT12J”, and to establish its reliability, validity, and responsiveness.MethodsTo assess test-retest reliability, an identical set of patients reported outcome measures with five qualitative scoring measures including iHOT12; these were filled out by each patient twice. Reliability was explored using Cronbachss alpha and intraclass correlation coefficient. The Bland–Altman plot was used to explore the absolute agreement. To evaluate validity, we examined the relationships between SF36 and iHOT12. Responsiveness was assessed by comparing the smallest detectable change to the minimal important change by applying an anchor-based approach.ResultsFifty patients (51 joints) were analyzed from March 2016 to October 2017 in Japanese four facility. The Cronbach α coefficient was 0.90 and the average value of intraclass coefficient (ICC) was 0.89. Bland–Altman plot analysis showed a solid agreement. Regarding the validity, the Spearman rank correlation coefficients were strong with PF (r = 0.69, p < 0.01), BP (r = 0.71, p < 0.01) and PCS (r = 0.69, p < 0.01). The smallest detectable change (3.19) was smaller than the minimum important change (12.40).ConclusionsWe developed iHOT12J, which seems to show sufficient reliability, validity, and responsiveness. We believe that this patient reported outcome measure is beneficial in studying Japanese patients with femoroacetabular impingement.     

Evaluation of the Korean version of the patient-rated wrist evaluation

Study designClinical measurements. Longitudinal.PurposeTo translate and cross-culturally adapt the original patient-rated wrist evaluation (PRWE) into a Korean version (K-PRWE), and to measure the reliability, validity, and responsiveness of the K-PRWE for the evaluation of distal radius fractures (DRFs).MethodsK-PRWE was developed by forward and backward translations of the PRWE and resolution of cultural discrepancies. Sixty-three DRF patients that underwent open reduction and volar plate fixation completed the K-PRWE at 3 months and 6 months postoperatively. Grip strength, wrist range of motion, VAS for wrist pain and the Korean version of DASH were performed at 3 months postoperatively. Reliability was measured by determining test-retest reliability (intraclass correlation coefficient) and internal consistency (Cronbach's alpha coefficient). Criterion and construct validity testing was performed using Spearman's correlation test. Responsiveness was evaluated using effect size (ES) and standardized response mean (SRM).ResultsCronbach's alpha coefficient and the intraclass correlation coefficient of the K-PRWE were 0.94 and 0.96, respectively, which indicated that the internal consistency of the questionnaire items was sound and reliable. The correlation coefficient between K-PRWE and K-DASH scores was 0.74 and between K-PRWE and VAS scores was 0.69. Responsiveness was good with an ES of 0.84 and an SRM of 0.89.ConclusionsThe Korean version of the PRWE was found to be reliable, valid, and responsive to evaluate the pain and disability associated with distal radius fractures.     

Reliability and validity of the Japanese version of the pelvic floor distress inventory-short form 20

Introduction and hypothesis

The aim of this study was to translate the Pelvic Floor Distress Inventory-Short Form 20 (PFDI-20) into Japanese and test its reliability and validity among Japanese women.

Methods

Fifty-nine women with and without pelvic floor disorders (age 55.8?±?16.8 years, mean ± SD) completed the Japanese PFDI-20 (J-PFDI-20) questionnaire at baseline and 2 weeks later. Intraclass correlation coefficients (ICC) and the Bland and Altman method for test-retest reliability and Cronbach’s alpha for internal consistency of the J-PFDI-20 were used. Scores of total and subscales were compared between women with and without pelvic floor disorders for known-groups validity. Spearman’s correlation coefficients between the J-PFDI-20 and the severity of pelvic floor disorders and Urinary Incontinence Quality of Life Scale (I-QOL) were used for construct validity.

Results

The PFDI-20 was successfully translated from English into Japanese with face validity through rigorous cross-cultural validation. Test-retest reliability of the J-PFDI-20 and three subscales was good to excellent (ICC?=?0.77–0.90). The Bland and Altman analysis showed that differences between the first and second scores of total J-PFDI-20 and its subscales were not significantly different from 0 and largely fell within the range of 0?±?1.96 SD. Cronbach’s alpha values were 0.52–0.83. Analysis of known-groups validity showed differences in scores of the J-PFDI-20 between women with and without pelvic floor disorders. Acceptable construct validity was found in J-PFDI-20 total and subscale scores with positive correlations to severity of pelvic floor disorders (ρ?>?0.35) and negative correlations to I-QOL (ρ?<?-0.39).

Conclusions

The results suggest that the J-PFDI-20 is a reliable and valid condition-specific quality of life instrument for women with pelvic floor disorders.     

Cross-cultural adaptation and psychometric testing of the Hindi version of the patient-rated wrist evaluation

The purpose of this study was to perform cross-cultural adaptation and Hindi translation of the patient-rated wrist evaluation (PRWE) and assess psychometric properties of the PRWE-Hindi. Cross-cultural adaptation and Hindi translation of the PRWE was performed using standardized guidelines. Intraclass correlation coefficient (ICC) was used for assessing test-retest reliability, and Cronbach's alpha (CA) was used for assessing the internal consistency of the PRWE-Hindi. Construct validity was assessed by examining the correlations between the PRWE-Hindi and grip strength, wrist range of movements, and self-reported pain and disability. A total of 50 patients with distal radius fracture were recruited and assessed three times (baseline, two to three days later, and four to five weeks later). PRWE-Hindi demonstrated excellent test-rest reliability (ICC=0.81) and internal consistency (CA=0.89). Moderate to low correlations (r<0.7) were observed between the PRWE-Hindi and other measures of pain and disability. Our results indicated that PRWE-Hindi is a reliable and valid tool and can be used in patients with wrist/hand injuries whose primary language is Hindi. LEVEL OF EVIDENCE: N/A.     

Acceptability, reliability, validity and responsiveness of the Turkish version of WOMAC osteoarthritis index

OBJECTIVE: To evaluate the acceptability, reliability, validity and responsiveness of the Turkish version of Western Ontario and McMaster Universities (WOMAC) osteoarthritis (OA) index in physiotherapy outpatient practice in Turkey. METHOD: Data were obtained from 72 patients with OA of the knee. They were asked to answer two disease-specific questionnaires (WOMAC LK 3.1 and Lequesne-Algofunctional Index of Severity for the knee) and one generic instrument (Medical Outcomes study SF-36 Survey-SF-36). Acceptability was assessed in terms of refusal rate, rates of missing responses, and administration time. Reliability was assessed using Cronbach's alpha. Content validity was assessed by examining the floor and ceiling effects, and skew of the distributions. Convergent and divergent validity was assessed by examining the Pearson's correlation coefficients. Responsiveness was determined by examining effect size (ES), standardized response means (SRM) and P values generated using Wilcoxon's test. RESULTS: The overall response rate was 100%. Alpha values for all WOMAC subscales exceeded the value of 0.70 at both baseline and follow-up assessments. Frequency distributions of scores were symmetrical. Subscales had negligible floor and ceiling effects. Both pain and physical function subscales were fairly correlated with the subscales measuring similar constructs of SF-36, whereas they were weakly correlated with other dimensions of SF-36. A good correlation was obtained between WOMAC total and Lequesne index. The pain and physical function subscales of WOMAC index were the most responsive subscales. CONCLUSION: The Turkish WOMAC OA index is acceptable, valid, reliable and responsive for use in Turkish patients with knee OA.     

Reliability and validity of measuring version of the acetabular component

A variety of radiological methods of measuring version of the acetabular component after total hip replacement (THR) have been described. The aim of this study was to evaluate the reliability and validity of six methods (those of Lewinnek; Widmer; Hassan et al; Ackland, Bourne and Uhthoff; Liaw et al; and Woo and Morrey) that are currently in use. In 36?consecutive patients who underwent THR, version of the acetabular component was measured by three independent examiners on plain radiographs using these six methods and compared with measurements using CT scans. The intra- and interobserver reliabilities of each measurement were estimated. All measurements on both radiographs and CT scans had excellent intra- and interobserver reliability and the results from each of the six methods correlated well with the CT measurements. However, measurements made using the methods of Widmer and of Ackland, Bourne and Uhthoff were significantly different from the CT measurements (both p < 0.001), whereas measurements made using the remaining four methods were similar to the CT measurements. With regard to reliability and convergent validity, we recommend the use of the methods described by Lewinnek, Hassan et al, Liaw et al and Woo and Morrey for measurement of version of the acetabular component.     

Reliability,validity and responsiveness of the cross-culturally adapted Italian version of the core outcome measures index (COMI) for the neck

Purpose

Evaluation of the psychometric properties of a cross-culturally adapted questionnaire, the Core Outcome Measurement Index for neck pain (COMI-neck).

Methods

The COMI-neck was cross-culturally adapted for the Italian language using established procedures. The following psychometric properties of the instrument were then assessed in patients with chronic neck pain undergoing rehabilitation: test–retest reliability (intraclass correlation coefficient, ICC); construct validity by comparing COMI-neck with the Neck Pain and Disability Scale, a numerical pain rating scale, and the EuroQol-Five Dimension (Pearson’s correlations); and responsiveness by means of Standardized Response Mean (SRM), unpaired t tests, and Receiver Operating Characteristics (ROC) curves.

Results

The questionnaire was completed by 103 subjects. The COMI-neck summary score displayed no relevant floor or ceiling effects. Test–retest reliability was excellent (ICC = 0.87). With one exception (symptom-specific well-being), the individual COMI items and the COMI summary score correlated to the expected extent with the scores of the reference questionnaires (r = 0.40–0.80). The mean change scores for the Italian COMI-neck differed significantly between patients with a good global outcome and those with a poor outcome (p = 0.002); SRM for the good outcome group was 1.23, and for the poor outcome group 0.40. ROC analysis revealed an area under the curve of 0.73 (95 % CI: 0.62–0.85).

Conclusions

This study provides evidence that the Italian version of the COMI-neck is a valid and responsive questionnaire in the population of patients examined. Its use is recommended for clinical and research purposes.

Reliability and validity of Turkish version of the Scoliosis Japanese Questionnaire- 27 in patients with adolescent idiopathic scoliosis

BackgroundThe aim of this study was to evaluate the reliability and validity of an adapted Turkish version of the Scoliosis Japanese Questionnaire- 27 (SJ- 27).MethodsTranslation and retranslation of the English version of the SJ- 27 was conducted, and all steps of the cross-cultural adaptation process were performed. The Turkish version of the SJ- 27, the Scoliosis Research Society-22 (SRS- 22) questionnaire and the Short Form-36 (SF- 36) were performed to 139 patients with AIS. Reliability was assessed using the test–retest method (Pearson's correlation coefficient); internal consistency was analyzed using Cronbach's alpha. Validity was assessed by correlating the SJ- 27 with the SRS- 22 questionnaire and SF- 36.ResultsThe mean Cobb angles were 23.2 ± 8.3° and 19 ± 5.9° for thoracic and lumbar regions, respectively. The SJ- 27 showed excellent test/retest reliability with an Intraclass correlation coefficient of 0.99. Internal consistency of the SJ- 27 was found to be very good (Cronbach's alpha = 0.991). The SJ- 27 demonstrated very good construct validity with the SRS- 22 total score (r = 0.61). The similar domains of the SJ- 27 and SF- 36 questionnaire was correlated also in the study.ConclusionsThe Turkish version of the SJ- 27 to measure health related quality of life in adolescent idiopathic scoliosis was found to have very good validity, excellent reliability, and high internal consistency.     

Validity, reliability and responsiveness of the Japanese version of the Neck Disability Index

Background

The Neck Disability Index (NDI) is one of the most widely used questionnaires for neck pain. The purpose of this study was to validate the Japanese NDI.

Methods

We performed two surveys with an 8-week interval in 130 patients with neck pain, radiculopathy and myelopathy. We asked patients to answer two versions of the Japanese NDI: the original NDI, which had been completed by a forward–backward translation procedure, and the modified NDI, which has the phrase “because of neck pain” to the phase “because of neck pain or numbness in the arm.” The other parameters examined were the strength of pain and numbness, the Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire, the Hospital Anxiety and Depression Scale, and Short Form 36. Attending surgeons judged the symptom severity. Patients were asked to report the patient global impression of change (PGIC) at the second survey. The internal consistency, criterion-related and discriminative validity, and reliability were evaluated.

Results

The original NDI and the modified NDI were 26.9 ± 17.1 and 29.9 ± 15.5, respectively. The Cronbach α values of the original NDI and the modified NDI were 0.92 and 0.89, respectively. Both versions of the NDI had good to excellent correlative coefficients with the related domains. The modified NDI had a higher validity for numbness and mental health-related QOL. The symptom severity was significantly correlated with the modified NDI. The intraclass correlation coefficients of the two surveys of the modified and original NDI were comparable. The effect sizes of the modified and the original NDI were 0.64 and 0.55, respectively. Spearman’s ρ between the change of the NDI and the PGIC was 0.47 in the original NDI and 0.59 in the modified NDI.

Conclusions

We demonstrated the validity, reliability and responsiveness of the Japanese NDI. The modified NDI was more strongly correlated with numbness and mental health-related QOL.
