The validity and reliability of the Arabic version of the Japanese Orthopedic Association Back Pain Evaluation Questionnaire: Can we implement it in Saudi Arabia?

Arabic-Translated Versions of Patient-Reported Outcome Measures Utilized in Spine Research: A Review of Validated Studies

Patient-reported outcome measures (PROMs) are standardized tools commonly applied in research and healthcare appraisal. Most were developed in English and the cross-cultural adaptation (CCA) and validation of their translated versions remain topics of contemporary research appeal. This review aimed to identify the Arabic-translated PROMs that were utilized in spine research and to assess the methodological qualities of their studies. The PubMed database was searched, and all relevant publications were identified. The CCA and measurement properties were assessed using the guidelines described by Oliveria and Terwee respectively. Thirty studies that validated the Arabic versions of 26 PROMs were found suitable. The tools that had the highest total citation numbers were Neck Disability Index, Ronald-Morris Disability Questionnaire, Oswestry Disability Index, Fear Avoidance Beliefs Questionnaire, Scoliosis Research Society-22, Back Beliefs Questionnaire, Quebec Back Pain Disability Scale, and McGill Pain Questionnaire-Short Form. The Arabic versions of Short Form-36 (SF-36), Visual Analogue Scale (VAS), and EuroQol-5D (EQ-5D) were not included due to lack of validation in spine research. All the articles were published from 2007 to 2023 (median 2019) and their journal's impact factor and citation numbers were relatively modest (mean 2 and 6.5 respectively). Most patients had low back pain (19 articles), were recruited from physiotherapy and rehabilitation departments (18 articles) and came from the Kingdom of Saudi Arabia (12 articles). The quality of the CCA of the Arabic versions was rated good in forward translation, synthesis, back translation, and expert committee review but less so in pretesting and submission. The measurement properties of the studies were considered good quality in internal consistency, reliability, structural validity and cross-cultural validity but less so in content validity, error measurement, responsiveness and floor/ceiling effect. In conclusion, with a few exceptions, most of the widely utilized PROMs in spine research have validated Arabic versions. The methodological quality of the studies was good apart from a few shortages that could be improved upon by further research. Work should be done to address the validation of Arabic versions of SF-36, VAS and EQ-5D in spine research. PROMs are valuable in systematizing subjective outcomes. Their usage in research and clinical settings in any validated language should be highly encouraged.

Comprehensive Assessment of Indirect Decompression Through Lateral Lumbar Interbody Fusion for Degenerative Lumbar Spinal Stenosis: A Japanese Orthopedic Association Back Pain Evaluation Questionnaire-Based Analysis

STUDY DESIGN

A retrospective study.

OBJECTIVE

This study aimed to comprehensively evaluate the clinical outcomes of lateral lumbar interbody fusion (LLIF) as an indirect decompression technique for degenerative spondylolisthesis (DS) and concomitant degenerative lumbar spinal stenosis (DLSS) patients. We utilized the Japanese Orthopedic Association Back Pain Evaluation Questionnaire (JOABPEQ) to assess treatment success and its impact on patient's quality of life (QOL).

METHODS

We included 124 patients who underwent LLIF. Pre- and postoperative JOABPEQ evaluations indicated treatment success. Subgroup analysis categorized patients' perceptions of surgery as beneficial or non-beneficial.

RESULTS

89% of patients (110/124) reported satisfaction with LLIF. Lateral lumbar interbody fusion achieved successful indirect decompression, increasing canal diameter and central canal area. Significant improvements occurred across all JOABPEQ domains, notably for low back pain, lumbar function, walking ability, social life function, and mental health. Patients who perceived the surgery as beneficial experienced fewer postoperative complications, lower numeric rating scale scores for pain relief, and greater functional outcome improvements compared to non-beneficial patients.

CONCLUSIONS

Our findings highlight the utility of JOABPEQ as a valuable and sensitive tool for assessing treatment effectiveness and patient-reported outcomes in DS and concomitant DLSS patients. Patients undergoing LLIF. The results affirm the favorable outcomes of LLIF as a surgical option for DLSS patients and emphasize the importance of considering patient perspectives when evaluating overall treatment success. The study provides valuable insights into the impact of indirect decompression on patients' QOL, supporting the effectiveness of LLIF as a minimally invasive technique for DLSS and DS management.

Cross-cultural adaptation of The Japanese Orthopaedic Association Back Pain Evaluation Questionnaire: A methodological systematic review

BACKGROUND

The Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) is a reliable and sensitive measure of disability to determine functional status and evaluate curative effects in low back pain, it has now been cross-cultural translated into many other languages and adapted for use in different countries. We aim to evaluate the translation procedures and measurement properties of cross-cultural adaptations of the JOABPEQ.

METHODS

Studies related to cross-cultural adaptation of the JOABPEQ in a specific language/culture were searched in PubMed, Embase, CINAHL, SciELO, PsycINFO, SinoMed, and Web of Science from their inception to March 2022. The Guidelines for the Process of Cross-Cultural Adaptation of Self-Report Measures and the Consensus-based Standards for the Selection of Health Status Measurement Instruments guideline were used for evaluation.

RESULTS

Nine different versions of cross-cultural JOABPEQ adaptations in 8 different languages/cultures were included. The adaptation process was not strictly performed, such as standard forward translation and expert committee review were rarely reported. Content validity (8/9), floor and ceiling effects (3/9), reliability (4/9), and interpretability (6/9) were assessed in most of the adaptations, while agreement (2/9), responsiveness (2/9), and the internal consistency (2/9) were not. JOABPEQ can replace functional and quality of life score to reduce the burden of scientific research.

CONCLUSION

We recommend Persian-Iranian, simplified Chinese-Chinese Mandarin, Thai and Gunaydin G's Turkish adaptations for application. The numerical pain rating scale/visual analogue scale in low back pain and lower extremities, as well as numbness in lower extremities could not be neglected in JOABPEQ adaptations.

Developing a Measure to Quantify Ocular Pain Postoperatively: The Adaptation of the Ocular Pain Assessment Survey

Purpose

Since quantification and communication of ocular pain is important for a healthier patient follow-up and postoperative guidance, reliable measures like the Ophthalmic Pain Assessment Survey (OPAS) are needed to assess the outcome and management of different operations. To address that need, we carried out the adaptation of OPAS into Turkish to reach different age groups and backgrounds, widening the use of OPAS on patients who underwent an ophthalmic operation.

Methods

We used back-translation method and achieved cultural adaptation through content validity scoring by 5 independent ophthalmologists. The survey is then administered three times: preoperatively, postoperatively within 24 hours, and finally a week later in the follow-up visit. Validity is measured in comparison to Visual Analog Scale using Spearman's correlation coefficient and reliability is measured using Cronbach's alpha. Factor analysis is performed by principal component analysis and rotation is performed using Varimax method when necessary.

Results

We reached a total of 132 patients with a mean age of 64.2 years. Most of them underwent phacoemulsification (n = 83), followed by PRK (n = 37). Overall, the T-OPAS demonstrated good reliability (mean C. alpha: 0.830) and its correlation with the VAS was especially high (S. coeff. >0.5) in the first three sections in all three surveys. Factor analysis yielded 5 subscales, allowing us to shape the final form of T-OPAS.

Conclusion

Through this adaptation of OPAS into a foreign language, we present a reliable and valid tool for postoperative pain quantification, allowing objective measurement of pain in different populations such as the elderly.

Structural validity of the Japanese Orthopedic Association back pain evaluation questionnaire in individuals with chronic low back pain

OBJECTIVE

The main aim of this study was to evaluate the structural validity of the Brazilian version of the Japanese Orthopedic Association Back Pain Evaluation Questionnaire (JOABPEQ).

METHODS

Individuals with chronic low back pain were included. The data collection of the study occurred by means of online platform. Confirmatory factor analysis was performed. The theoretical version proposed for the JOABPEQ with five domains was tested. The following indices were considered to verify the fit of the model: comparative fit index (CFI), Tucker-Lewis index (TLI), root mean square error of approximation (RMSEA), and chi-square/degrees of freedom (DF).

RESULTS

The final sample consisted of 175 volunteers, mostly women (68%), adults (mean age of 28.98 years), lean (mean body mass index of 25 kg/m2), with incomplete higher education, single, with mean of pain chronicity of 61.50 months and mean of pain intensity of 6.78 points on the Numeric Pain Scale. Regarding the structure of the JOABPEQ, the original version with five domains was adequate: chi-square/DF=1.52, CFI=0.954, TLI=0.948, and RMSEA=0.055. The factorial load ranges from 0.41 to 0.90.

CONCLUSIONS

This study confirms the structure of JOABPEQ with 5 domains (low back pain, lumbar function, walking ability, social life function, and mental health) and 25 items in individuals with chronic low back pain.

A comparison between the low back pain scales for patients with lumbar disc herniation: validity, reliability, and responsiveness

Background

Although the Japanese Orthopedic Association Back Pain Evaluation Questionnaire (JOABPEQ), Numerical Pain Rating Scale (NPRS), Oswestry Disability Index (ODI), Roland Morris Disability Questionnaire (RMDQ), and Short Form 36 Health Survey (SF-36) has shown a preferable psychometric properties in patients with low back pain (LBP), but no study has yet determined these in conservative treatment of patients with lumbar disc herniation (LDH). Thus the current study aimed to compare those scales in LDH patients receiving conservative treatment to select the better option to assess the severity of disease.

Methods

LDH patients were invited to complete the JOABPEQ, NPRS, ODI, RMDQ, and SF-36 twice. The internal consistency was evaluated by the Cronbach’s α. Test-retest reliability was tested by the intraclass correlation coefficient (ICC). The relationships of these scales were evaluated by the Pearson correlation coefficients (r). The responsiveness was operationalised using the receiver operating characteristic (ROC) curve, as well as the comparison of smallest detectable change (SDC), minimum important change (MIC).

Results

A total of 353 LDH patients were enrolled. Four subscales of the Chinese JOABPEQ were over 0.70, then the ICCs for the test-retest reliability were over 0.75. For functional status, remarked negative correlations could be seen between JOABPEQ Q2-Q4 and ODI, as well as RMDQ (r = − 0.634 to − 0.752). For general health status, remarkable positive correlations could also be seen between Q5 Mental health and SF-36 PCS (r = 0.724) as well as SF-36 MCS (r = 0.736). Besides, the area under of the curves (AUC) of the JOABPEQ ranged from 0.743 to 0.827, indicating acceptale responsiveness, as well as the NPRS, ODI, and RMDQ.

Conclusion

NPRS, and ODI or RMDQ is recommended in studies related to LDH patients, while if the quality of life also is needed to observe, the NPRS, and JOABPEQ would be more appropriate rather than SF-36.

Responsiveness of the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire in lumbar surgery and its threshold for indicating clinically important differences

BACKGROUND CONTEXT

Introduced in 2007, the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) has been widely used, but its psychometric properties have not been well studied.

PURPOSE

The objective of this study was to assess the responsiveness of the JOABPEQ in lumbar surgery and its threshold for indicating clinically important differences.

STUDY DESIGN

This is a prospective study.

PATIENT SAMPLE

Two hundred three consecutive patients underwent lumbar surgeries between July 2013 and November 2015 in a single hospital. Of the 203 patients, 181 patients who completed 1 year of follow-up were included.

OUTCOME MEASURES

Before and after surgery, the patients were asked to complete the questionnaire, including JOABPEQ, the 8-Item Short Form Health Survey (SF-8), and EuroQol-5D (EQ-5D). The participants were divided into five anchoring groups, ranging from "much better" to "much worse," according to reports from both physicians and patients.

MATERIALS AND METHODS

The responsiveness of measures was compared among five domains of the JOABPEQ ("low back pain," "walking ability," "lumbar function," "social function," and "mental health"), two domains of the SF-8 (the physical component summary [PCS] and the mental component summary [MCS]), and the EQ-5D. The responsiveness was assessed by the paired t test, the effect size, and the standardized response mean. The Spearman rank correlation coefficient and the receiver operating characteristic (ROC) curve were assessed using the five anchoring groups as external criteria. The clinically important differences, based on the ROC curve, were assessed.

RESULTS

Walking ability was most responsive, followed by low back pain and the PCS. The MCS was least responsive, followed by mental health and lumbar function. Social function and the EQ-5D had intermediate-level responsiveness. The substantial clinically important differences occurred at 20 points for low back pain and lumbar function, 23 points for walking ability, 14 points for social function, and 8 points for mental health.

CONCLUSIONS

The JOABPEQ domains are responsive measures in patients who undergo lumbar surgery. For physical function, the threshold for substantial clinically important differences was approximately 20 points for the JOABPEQ.

Simplified Chinese Version of the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire: Agreement, Responsiveness, and Minimal Important Change for Patients With Chronic Low Back Pain

STUDY DESIGN

Psychometric test of the cross-cultural adaptation the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) in low back pain (LBP) patients.

OBJECTIVE

To investigate the agreement, responsiveness, and minimal important change (MIC) of the simplified Chinese version of the JOABPEQ in LBP patients.

SUMMARY OF BACKGROUND DATA

The factor structure, internal consistency, test-retest reliability, validity, floor and ceiling effect of simplified Chinese JOABPEQ have been tested, while the agreement, responsiveness, and MIC were required.

METHODS

The agreement, responsiveness, and MIC of the simplified Chinese version were assessed by completing the Chinese JOABPEQ twice. Agreement was tested with Bland-Altman plot. Responsiveness was operationalized using receiver operating characteristic analyses. The anchor-based method was used to calculate MIC.

RESULTS

One hundred sixty-two of 184 patients returned to finish the booklet twice were available for analysis (response rate: 88.0%). While the responsiveness, the area under the curves of each subscale were ranged from 0.746 to 0.875, which meant a good responsiveness. While the MIC (MIC%) of simplified Chinese JOABPEQ was 19.28 (44.98%) for Q1 Low back pain, 15.20 (24.13%) for Q2 Lumbar function, 15.79 (22.76%) for Q3 Walking ability, 9.58 (19.86%) for Q4 Social life function, 7.33 (17.28%) for Q5 Mental health. While compared with the MIC, only the Q3 Walking ability had a positive rating for agreement in the Bland-Altman plot.

CONCLUSION

The simplified Chinese JOABPEQ has positive agreement of Q3 Walk ability and acceptable to excellent responsiveness of all the subscales. The MICs for subscales of the simplified Chinese JOABPEQ ranged from 7.33 to 19.28 points.

Cultural adaptation, reliability and validity of Japanese Orthopaedic Association Back Pain Evaluation Questionnaire to Brazilian Portuguese

OBJECTIVE

To describe the translation and cultural adaptation of the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire into Brazilian Portuguese, and verifies the reliability and validity of this new version.

METHODS

A cross-cultural adaptation of the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire was performed using the following steps: translation, back-translation, committee review, and pre-testing phase (50 subjects). The psychometric properties were evaluated by application of the questionnaire to 102 patients. Reliability was assessed by homogeneity and stability of measures. The criterion-related validity was tested by comparing scores of Japanese Orthopaedic Association Back Pain Evaluation Questionnaire to Oswestry and Medical Outcomes Study 36 - Item Short questionnaires.

RESULTS

Excellent internal consistency was found in both test (Cronbach's α of 0.90) and re-test (Cronbach's α of 0.91). The Japanese Orthopaedic Association Back Pain Evaluation Questionnaire showed good reliability and the correlations ranged from reasonable (0.64) to very good (r=0.91).

CONCLUSION

The Brazilian Portuguese version of Medical Outcomes Study 36 - Item Short was easy to apply and understand. The questionnaire had a great impact on assessment and multidimensional care of patients with low back pain.
