Cross-cultural Adaptation and Psychometric Properties of the Arabic Version of the Rapid Assessment of Physical Activity.

ABSTRACT: Objectives:The purpose of the study was to cross-culturally adapt the Rapid Assessment of Physical Activity (RAPA) for Arabic speaking people and examine the test-retest reliability and the construct validity in Saudi older adults. Methods:Test-retest reliability was assessed over two testing visits occurring one week apart. The construct validity was examined between RAPA and Short Physical Performance Battery (SPPB) and Timed Up and Go (TUG) tests. Results:The original RAPA was translated into Arabic following standardized guidelines. For the test-retest reliability, the weighted kappa was 0.87 (95% confidence interval: 0.76-0.98), which indicates good reliability. There was a significant correlation between the Arabic version of RAPA and the SPPB (Spearman's correlation coefficients (r) = 0.536, p < 0.001), and the TUG test (r = -0.435, p < 0.010). Conclusions:The Arabic version of the RAPA questionnaire adapted for Saudi older adults provides an easy, valid, and reliable way to measure physical activity.

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 Modified Low Back Pain Disability Questionnaire (MLBPDQ) is used for evaluating the functional disability in patients with low back pain (LBP). However, the measurement characteristics of the MLBPDQ among Arab patients are unknown. In this study, we aimed to translate and cross-culturally adapt the MLBPDQ into Arabic and evaluate its psychometric properties.MethodsAn Arabic version of the MLBPDQ 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 α), 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.ResultsThe culturally aligned MLBPDQ showed good internal consistency (Cronbach’s α = 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-MLBPDQ was 0.68, and the MIC was 3 points.ConclusionThe Arabic version of the MLBPDQ demonstrates adequate psychometric properties and can be used to assess disability level in patients with LBP in Arabic-speaking communities.

Project description:BackgroundMenopause Rating Scale (MRS) evaluates eleven menopausal symptoms and health related quality of life (HRQOL) of postmenopausal women under three subscales. In this study we attempted cross cultural adaptation and evaluation of psychometric properties of a Sinhala translation of MRS.MethodsSinhala version of MRS was adapted following standard methodology; forward and backward translations, review by an expert group, focus group discussion (FGD) and pre-testing. It was self-administered among randomly selected healthy, Sinhalese, community-dwelling 166 postmenopausal women (aged; median?=?56.5, IQR, 53.0-59.0 years) along with the Short Form 36 (SF-36) survey questionnaire. MRS was re-administered among a subsample (n?=?80) after two weeks of first administration. Psychometric properties; reliability and validity were evaluated.ResultsIn Sinhala version of MRS, both internal consistency (Cronbach's alpha coefficient?=?0.79) and test retest reliability (intra class correlation / ICC?=?0.86, 95%CI?=?0.82-0.91, p?<?0.001 and Pearson correlation / r?=?0.93) were high. Factor analysis (FA) with Principal Component Analysis (PCA) extracted three factors explaining 59.82% cumulative variance with few exceptions from the original version. In the item-subscale correlation analysis items showed stronger correlations within their own subscale score (r range between 0.56-0.84) than with other subscales scores and subscales' scores showed strong correlations with the overall MRS score (r range between 0.70-0.86) indicating strong convergent validity. Mean (SD) symptom severities of each item were significantly different between symptomatic and asymptomatic women (p?<?0.05) emphasizing good discriminant validity. The overall MRS and SF-36 scores correlated significantly (Pearson correlation: -?0.52, p?<?0.01 and Kendall's tau-b: -?0.39, p?<?0.01) ensuring strong criterion validity.ConclusionsThe Sinhala version of MRS we adapted is an informative tool with high reliability and validity and this tool can be used to evaluate the menopausal symptoms and HRQOL in postmenopausal women conversant in Sinhala.

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:IntroductionPhysical activity level during pregnancy is unknown in Middle Eastern and North African countries, since no valid tools assessing it exist in Arabic. The aim of this study is to culturally adapt and translate to Arabic an internationally validated instrument, the Pregnancy Physical Activity Questionnaire (PPAQ), and to measure the physical activity of pregnant women using the adapted PPAQ, Arabic version. This tool is time-sparing, self-administered and is the only one taking into account childcare and household chores.MethodsAfter following the guidelines for translation and back-translation by certified translators, a committee composed of professionals in the field reviewed each item of the PPAQ, for its comprehensibility. This Arabic version of the PPAQ was tested on a sample of 179 pregnant Lebanese women, from different educational backgrounds, socioeconomic status and gestational ages.ResultsCross-cultural adaptations were applied on the newly translated PPAQ in Arabic version, thus questions referring to some types of outdoor activities were excluded from the final format. Our results reported that 51% and 1.7% of women engage respectively in light and high intensity physical activity, while 18% had a sedentary lifestyle. Occupational type of activities were significantly more performed by women having a higher education (p value 0.001), as opposed to those who attended only high school, who were physically more active in household activities (p value 0.038). Second trimester was a period where pregnant women were active for household, caregiving (p value 0.031), whereas women in their third trimester were physically more active in occupational activities (p value 0.001). Sport-oriented activities were performed by women reporting a good physical status (p value 0.03). Age and crowding index were significantly correlated with occupational, household and caregiving activities (p values 0.004, 0.008 respectively). No significant correlations were observed with pre-gestational body mass index and the physical activity levels.ConclusionA valid tool will help researchers in Arab countries identify physical activity levels of pregnant women and consequently emit specific guidelines relative to the importance and the benefits of a daily active lifestyle throughout gestation.
