Background: The first step to successful aging planning is to assess the current status using valid instruments. This study aimed to evaluate the psychometric properties of the Persian version of the Successful Aging Inventory (SAI). Materials and Methods: In the first step, SAI. was translated through forward-backward translation, and its face and content validity were qualitatively and quantitatively assessed. For construct validity assessment, 300 elderly were recruited through multi-stage random sampling. Exploratory factor analysis and known-group comparison were used. SAI reliability through internal consistency and stability was assessed using the Cronbach’s alpha values of the inventory and intraclass correlation coefficient (ICC), respectively. The standard error of measurement, smallest detectable change, and floor and ceiling effects were calculated. Results: The impact scores, content validity ratios, and content validity indices of all items were more than 1.5, 0.62, and 0.8, respectively. The scale-level content validity index was 0.94. Factor analysis identified four factors for the inventory, which explained 58.17% of the total variance of the SAI score. SAI mean score among mentally healthy participants was significantly higher (P<0.001). The relative frequencies with the lowest and highest possible scores of SAI were 0 and 3.7%, respectively. The Cronbach’s alpha, ICC, standard error of measurement, and the smallest detectable change of SAI were 0.835, 0.999, ±0.47, and 1.9, respectively. Conclusion: As a valid and reliable instrument, the Persian version of SAI could be used for a successful aging assessment. [GMJ.2020;9:e1754]

Background The Keele STarT MSK Tool is a 10-item questionnaire developed to classify patients suffering from one of the five most common types of musculoskeletal pain into 3 sub-groups of risk of chronic pain (i.e. low risk, medium risk and high risk). Objective The objective of the present study was to translate the Keele STarT MSK Tool into French and to evaluate its main psychometric properties. Methods The translation and intercultural adaptation of the questionnaire were carried out using a 6-step process. The following psychometric properties were investigated: floor and ceiling effects, construct validity, internal consistency and test-retest reliability including Standard Error of Measurement and Smallest Detectable Change. Results 101 patients suffering from musculoskeletal pain participated in the study. No floor nor ceiling effects were observed. A Cronbach’s alpha of 0.65 was found, revealing a moderate internal consistency. Nevertheless, all items were demonstrated to be significantly correlated with the total score (range of correlations: r=0.2 for item 7 to r=0.78 for item 1). A good construct validity was also found with a significant correlation of r=0.78 between the French Keele STarT MSK Tool and the ÖMPSQ-short. Test-retest reliability was excellent (Intraclass Correlation Coefficient 0.97). A Standard Error of Measurement of 0.42 and a Smallest Detectable Change of ±1.17 were measured. Conclusion A validated French version of the Keele STarT MSK Tool is now available and can be used by health practitioners to stratify patients as being at low, medium or high risk of persistent musculoskeletal pain.

Процветание имеет большое значение во всех возрастных группах, но оно становится еще более важным в период старения. Целью данного исследования была оценка психометрических свойств персидской версии PERMA-Profiler для использования его в качестве инструмента оценки успешности в жизни у пожилых иранцев. Это перекрестное исследование выполнено в три этапа. На первом этапе опросник был переведен на персидский язык с использованием метода прямого-обратного перевода; на втором этапе оценивали количественную и качественную достоверность лица, валидность контента и индекс валидности контента; на третьем этапе - анализ подтверждающего и поискового факторов, одновременная достоверность, сходящаяся и расходящаяся достоверность и надежность. Надежность опросника оценивали по α-коэффициенту Кронбаха, коэффициенту половины деления и стабильности по методу «тест-повторный тест». Наименьшее обнаруживаемое изменение и стандартная погрешность измерения были также рассчитаны. Персидская версия PERMA-Profiler с 14 элементами имела хороший коэффициент корреляции шкалы гериатрической депрессии и CASP-19 (0/545 GDS и 0,303 CASP-19). В исследовательском факторном анализе было выделено три фактора, которые объяснили 52 % дисперсию оценки PERMA-Profi ler. Факторный анализ подтвердил наличие трех факторов. Опросник показал хорошую стабильность и надежность ( р <0,0001, α=0,896, коэффициент корреляции Спирмена 0,745 и ICC=0,693). Стандартный размер ошибки был небольшим и приемлемым. Персидская версия PERMA-Profiler является подходящим инструментом для оценки качества жизни пожилых иранцев и выявления их успешности. Статья публикуется в авторской редакции. Flourishing is of great importance in all age groups, but it becomes even more important in the aging period. The aim of this study was the evaluation of the psychometric properties of the Persian version of PERMA-Profiler for using it as a flourishing assessment tool in Iranian older adults. This cross-sectional study implemented in 3 phases. In phase 1 - the questionnaire was translated into Persian using the forward-backward translation method; in phase 2 - quantitative and qualitative face validity, content validity, and content validity index were evaluated; in phase3 - confirmatory and exploratory factor analysis, concurrent validity, convergent and divergent validity, and reliability were evaluated. The reliability of the instrument was assessed by Cronbach’s alpha coeffi cient, split-half coefficient, and stability by the test-retest method. Smallest detectable change and Standard error of measurement were calculated, too. Persian version of the PERMA-Profiler with 14 items had a good correlation coefficient between with Geriatric Depression Scale and CASP-19 (0/545 GDS and 0,303 CASP-19). In exploratory factor analysis, three factors were extracted and explained 52 % of the variance of the PERMA-Profiler score. Confirmatory factor analysis confirmed the existence of three factors. The instrument showed good stability, repeatedly and reliability ( p <0,0001, α=0,896, Spearman correlation coefficient =0,745 and ICC=0,693). The standard error size was small and acceptable. The Persian version of the PERMA-Profi ler is an appropriate tool to measure the fl ourishing among the Iranian elderly and to identify successful older individuals.

Introduction The Patient-Rated Tennis Elbow Evaluation (PRTEE) questionnaire is a tool designed for self-assessment of forearm pain and disability in patients with tennis elbow. The aims of this study were to translate and cross-culturally adapt the PRTEE questionnaire into Persian and evaluate its reliability and construct validity. Methods The PRTEE questionnaire was translated into and cross-culturally adapted to Persian in 90 consecutive patients with tennis elbow, according to well-established guidelines. Reliability was tested by means of test–retest and internal consistency. The measurement error was measured by calculating the standard error of measurement. Based on the standard error of measurement, the minimum detectable change was calculated. To evaluate construct and convergent validity, correlation with the PRTEE with the Disabilities of the Arm, Shoulder and Hand questionnaire and Visual analogue scale was used. Results In the process of cross-cultural adaptation, two items (6 and 8) were modified. In item 6, the term “door knob” was changed to “turn a key”, and in the item 8, “cup of coffee” was changed to “cup of milk”. Item-total correlations were greater than 0.55 (ranged from 0.55 to 0.76), internal consistency was high (Cronbach’s alpha, 0.94) and a high intraclass correlation coefficient (0.98) indicated excellent reliability of the P-PRTEE. The standard error of measurement and minimum detectable change were 5.40 and 14.24, respectively. The Persian version of the PRTEE questionnaire (P-PRTEE) shows strong construct and convergent validity ( r values = 0.85, p < 0.05). Conclusions The P-PRTEE is valid and reliable in assessing disability and pain in Persian patients with tennis elbow. The excellent psychometric properties of the P-PRTEE endorse the use of this questionnaire in clinical settings.

Abstract BackgroundUntil 2008, Objective Structured Clinical Examinations (OSCE) were well researched, laborious and costly paper based method of exam delivery restricting international comparison. Cross-institutional comparison of OSCE Quality Assurance in Europe has never been done and due to wide spread electronic assessment analysis is now available.MethodsTwenty educational institutions across Europe using an electronic OSCE Management Information System where invited of which 8 confirmed to join a mutual comparison of Quality Assurance outcome. Two theories evaluate the quality of the observed test scores, the Classical psychometric theory (Cronbach’s alpha) and the Generalizability theory. Outcomes for both were compared for all universities including the Standard Error of Measurement (SEM) as well as cut-scores, Pass/Fail score and Global Rating Scores, Cronbach’s Alpha and related SEM (68% and 95% CI) and G-theory Coefficients with related absolute and relative SEM (68% and 95% CI). ResultsOutcomes differ between participating universities and observed marks contradict global rating of fail, borderline and excellent performance. G-theory coefficients and Standard Error of Measurement were lower and smaller compared to the classical approach using Cronbach’s Alpha as measure of reliability. The Classical psychometric based SEM varies from 2.8% to 11.2% respectively whereas the 95% CI equivalent varied from 9.2% up to 22% (on a 0 - 100% scale). The relative SEM from G-theory analysis varied from 3.1% to 7.0% for criterion-referenced marks, and the absolute SEM for norm-referenced marks varied from 3.8% to 7.8% respectively. The 95% CI around the relative and absolute SEMs values varied from 7.3% to 15.3%. More students failed the examination if the 95% CI is applied to the observed scores.ConclusionTo protect society and to improve educational decision making, the Standard Error of Measurement and associated confidence intervals needs to be embedded in EU assessment strategies to rule out ‘false positive Pass decisions’.

Objective. This study has been designed with the aim of using optimal scaling to perform the allocation of scores and to be able to construct an indicator of the Parkinson’s Disease Gravity Index. Scores were assigned to interrelated dimensions that share information about the patient’s situation, to have an objective, holistic tool which integrates scores so that doctors can have a comprehensive idea of the patient’s situation. Patients and Methods. 120 consecutive patients with Parkinson’s diagnosis were chosen according to the United Kingdom Parkinson’s Disease Society Brain Bank criteria. Subsequently, all the chosen dimensions were transformed into interval variables for which the formula proposed by Sturges was used. Once the dimensions were transformed into interval variables, optimal scaling was carried out. Subsequently, the following attributes were analyzed: quality and acceptability of the data; reliability: internal consistency, reliability index, Cronbach’s alpha, and standard error of measurement; finally, validity: convergent validity and validity for known groups. Results. There were no missing data. An appropriate Cronbach’s alpha value of 0.71 was gathered, and all items were found to be pertinent to the scale. The item homogeneity index was 0.36. Precision evaluated with the standard error of measurement was 7.8. The Parkinson’s Disease Gravity Index discriminant validity (validity for known groups), assessed among the different stages of Hoehn and Yahr scale by the Kruskal–Wallis test, showed major significance (X2 = 32.7, p ≤ 0.001 ). Conclusions. The Parkinson’s Disease Gravity Index has shown adequate metric properties.
