Cross-cultural adaptation and psychometric testing of the Arabic version of the Modified Oswestry Low Back Pain Disability Questionnaire.

ABSTRACT: BACKGROUND:The Modified Oswestry Low Back Pain Disability Questionnaire (MODQ) is used for evaluating the functional disability in patients with low back pain (LBP). However, the measurement characteristics of the MODQ among Arab patients are unknown. In this study, we aimed to translate and cross-culturally adapt the MODQ into Arabic and evaluate its psychometric properties. METHODS:An Arabic version of the MODQ was developed through forward translation, translation synthesis, and backward translation. Sixty-eight patients (55 males and 13 females) with a mean age 37.01 ± 7.57 years were recruited to assess its psychometric properties. Reliability was evaluated using internal consistency (Cronbach's ?), test retest reliability (utilizing intraclass correlation coefficient [ICC]), standard error of measurement (SEM), minimal detectable change at 95% confidence level (MDC95%), and 95% limits of agreement (LOA). The construct validity was investigated by correlating the new translation with four other measures of LBP (using Spearman's rho). Finally, receiver operating characteristic curve was constructed to compute the sensitivity, using the area under the curve (AUC), and the minimum important change (MIC). An alpha level of 0.05 was set for statistical tests and all the psychometric values were tested against a priori hypotheses. RESULTS:The culturally aligned MODQ showed good internal consistency (Cronbach's ? = 0.85). The ICC, SEM, MDC95%, and LOA between baseline and two days later were 0.98, 1.60, 4.43, and -4.23 to 7.70, respectively, while the values between baseline and 14 days later were 0.94, 2.77, 7.67, and -6.59 to 13.53, respectively. The scale also demonstrated moderate to excellent correlation (rho = 0.54-0.86) with the other four questionnaires. The AUC value of the Arabic-MODQ was 0.68, and the MIC was 3 points. CONCLUSION:The Arabic version of the MODQ demonstrates adequate psychometric properties and can be used to assess disability level in patients with LBP in Arabic-speaking communities.

Project description:BackgroundThe Extended Nordic Musculoskeletal Questionnaire (NMQ-E) had never been adapted into Arabic. We culturally adapted the NMQ-E to Arabic in five stages and investigated its psychometric properties.MethodsAfter translating and cross-culturally adapting the NMQ-E into Arabic, through forward translation, translation synthesis, backward translation, expert committee review, and pilot testing, the psychometric properties were investigated. The construct validity was assessed by having the participants completing the Arabic version of the NMQ-E with four Arabic scales that measured musculoskeletal pain in all regions covered in the NMQ-E. Participants' baseline records were also used to evaluate internal consistency (Cronbach's α). Seven days later, participants completed the Arabic NMQ-E again to evaluate its test-retest reliability employing intraclass correlation coefficient (ICC) and standard error of measurement (SEM) for the age questions, and Cohen's kappa coefficient (κ), the proportion of observed agreement (Po), the proportion of positive agreement (Ppos), and the proportion of negative agreement (Pneg) for the dichotomous items.ResultsA total of 127 participants, 70 males and 57 females with mean age 32.5 ± 12.2 years, were included. Significant differences were found between participants with and without musculoskeletal pain in the corresponding scales, signifying the content validity of the questionnaire. Cronbach's α for both the prevalence and consequences pain sections combined ranged from 0.30 to 1.00. The test-retest reliability of the age questions was excellent, with ICC values ranging between 0.995 and 1.00. The SEM was 0.77 for the neck region and 0 for the rest of the regions. The prevalence questions demonstrated almost perfect agreement, with κ values ranging between 0.82 and 1.00, the Po between 0.94 and 1.00, the Ppos between 0.80 and 1.00, and the Pneg between 0.93 and 1.00. The consequences of pain questions showed moderate-to-perfect agreement, with κ values ranging between 0.57 and 1.00, between 0.83 and 1.00 for the Po, between 0.50 and 1.00 for the Ppos, and between 0.86 and 1.00 for the Pneg.ConclusionsThe results suggest that the Arabic NMQ-E is a valid and reliable tool that can be used to screen Arab adults for the prevalence and consequences of musculoskeletal pain.

Project description:BackgroundThe EuroQol-5 Dimension (EQ-5D) is a generic self-administered questionnaire used for the measurement and economic valuation of a wide range of health conditions, which necessitates its existence and adaptation in different languages. Currently, the tool does not exist in any Nigerian language. This study aimed to translate, cross-culturally adapt, and determine the reliability and validity of the Yoruba version of the EQ-5D-5L questionnaire.MethodsThe International Quality of Life Assessment (IQOLA) project guidelines, involving forward translation, reconciliation and harmonization, backward translation, and reconciliation of problematic items were used in the Yoruba translated version of the EQ-5D-5L (EQ-5D-Yor). A total of 113 and 109 persons with musculoskeletal disorders participated in the validity and 7-day test-retest reliability testing of the EQ-5D-Yor. Convergent and discriminant validity of the EQ-5D-Yor were determined using the Yoruba version of the 12-Item Short-Form Health Survey (SF-12) (SF-12-Y) and Visual Analog Scale (VAS). Data were analyzed using descriptive and inferential statistics of Spearman correlation, Intra-Class Correlation, Cronbach alpha, and multi-trait scaling analysis. Alpha level was set as p < 0.05.ResultsThe construct validity of the EQ-5D-Yor yielded Spearman rho ranging from 0.438 to 1.000, with the EQ-VAS having the highest co-efficient (r = 1.000; p = 0.001). The convergent validity of the EQ-5D-Yor index with scales and domains of the SF-12-Y yielded no significant correlations (p < 0.05), except for the physical functioning scale (r = -0.709, p = 0.001). On the other hand, the divergent validity of the EQ-5D-Yor index with VAS yielded a moderate negative correlation (r = -0.482; p = 0.001). The Intra-class Correlation Coefficient (ICC) and Cronbach's alpha for the test-retest reliability of the EQ-5D-Yor were 1.000 and 0.968. The confirmatory factor analysis showed the factor loadings were poor when including VAS in the model.ConclusionThe EQ-5D-Yor has acceptable validity and reliability and can be used as a valid tool among Yoruba speaking population with musculoskeletal disorders.

Project description:BACKGROUND:Despite the general agreement regarding the central role of the clinical learning environment in graduate medical education, its assessment remains challenging owing to the lack of available standardized measures. We report on the cross-cultural adaptation and psychometric assessment of the Brazilian-Portuguese version of Seelig's Resident Questionnaire. METHODS:The present study was performed in two steps. First, a cross-cultural translation and adaptation of the Resident Questionnaire was conducted through multiple translations, synthesis of versions, back-translation, content validation, and face validation. Subsequently, a sample of 288 (72%) resident physicians enrolled in 40 residency programs at a Brazilian university hospital completed the following measures: 1) the Brazilian-Portuguese version of the Resident Questionnaire (for factor analysis and to determine internal consistency, reliability, and validity); 2) three existing, validated psychometric measures (to determine convergent and divergent validity); and 3) a self-report questionnaire. RESULTS:Confirmatory factor analysis results provided support for the three-dimensional model of the Resident Questionnaire in use on a sample of Brazilian resident physicians, having been previously verified for use in American samples. All three factors (emotional distress, learning environment satisfaction, and workload satisfaction) verified in the confirmatory factor analysis showed good internal consistency (? > .80), reliability (Raykov's rho > .80), and correlations in the expected directions and magnitude with measures of depressive symptoms, duty hours, organizational conditions, and emotional exhaustion. CONCLUSIONS:This study is the first to adapt a measure of the clinical learning environment of residency programs into Brazilian Portuguese. Our findings suggest that the adapted version of the Resident Questionnaire is valid and reliable for assessing Brazilian residency programs. This free, easy-access, and fast-application instrument may be a useful standardized measure for research and educational purposes concerning the clinical learning environments of resident physicians.

Project description:BackgroundIn recent years, more importance is being given to the assessment of quality of life (QoL) among diabetic patients as a measure of their health and the goal of all health interventions. Other studies have reported a high prevalence of diabetes-related effects on; however, there is a knowledge gap in the region of Sub-Saharan Africa, as is the case for Rwanda, where the prevalence of diabetes is expected to rise over the next decade. The aim of this study is to report on the translation and cultural adaptation of the Diabetes-39 (D-39) questionnaire into the Kinyarwanda and its psychometric properties among diabetic patients in Rwanda.MethodsThe D-39 questionnaire-a five-scale, disease-specific QoL questionnaire-was translated from English to Kinyarwanda, then back-translated to English. A consensus meeting discussed discrepancies and agreed on changes. Interviews were conducted with 26 participants before producing a final version. For the psychometric evaluation, the adapted version was administered to 309 patients with diabetes mellitus. Participants either came from a separate cluster-randomised controlled trial or were recruited ad hoc for this study. The evaluation included testing internal consistency, known group validity, and construct validity.ResultsParticipants' mean age was 51 ± 12.7 years with a predominance of women (64%) in the sample. All five scales of the questionnaire showed a good internal consistency, with composite reliability of above 0.7. The five-factor model of the questionnaire was fitted to the 39 items. Although the fit was not exact, there was a satisfactory approximate fit (CFI = 0.93, TLI = 0.92, RMSEA = 0.05). There was a good discriminant validity except for the "social burden" and "anxiety and worry" scales (inter-factor correlation = 0.80).ConclusionsDiabetes-39 is a questionnaire developed in English that was adapted and translated into Kinyarwanda. The Kinyarwanda version of D-39 is a reliable and valid instrument to measure QoL among diabetic patients in Rwanda. The questionnaire can be helpful in research and clinical practice improving health outcomes for patients with diabetes in Rwanda and other Kinyarwanda-competent areas in the sub-region. However, certain cross-cultural differences should be considered.
