Objectives: Loneliness is a significant concern among the elderly and requires measurement and intervention. This study was conducted to translate and make a psychometric evaluation of the 6-item de Jong Gierveld loneliness scale in Iranian older people. Methods & Materials: This is a descriptive study carried out in 2018. After receiving permission from the tool designer, the original version of the 6-item de Jong Gierveld loneliness scale was translated into Persian by the translation and translation-back method. Then its face and content validities were determined. The final Persian version was completed by 224 eligible elderly residents in Khorramabad City, Iran. The data were analyzed using Confirmatory Factor Analysis (CFA), the Pearson correlation coefficient, the Intra-class Correlation Coefficient (ICC), and the Cronbach alpha. The SPSS and AMOS were used, and the significance was determined at the level of P≤ 0.05. Results: The Persian version of the 6-item de Jong Gierveld Loneliness Scale had an acceptable content validity (CVI=0.874). Confirmative factor analysis indicated the extraction of two factors: emotional loneliness and social loneliness (CMIN/DF=1.48, GFI=0.983, IFI=0.983, RMSEA=0.004). The overall loneliness score showed a significant correlation with the hospital anxiety and depression scale. The reliability of the scale was accepted by the intra-class correlation coefficient and the Cronbach alpha coefficient. Conclusion: The Persian version of the 6-item de Jong Gierveld loneliness scale is a reliable and valid measure of loneliness in Iranian elders.

The aim of this study was to determine the psychometric properties of the Persian version of pregnancy symptoms inventory. A methodological study. This study was conducted on 220 pregnant women. Construct validity was measured by exploratory factor analysis and confirmatory factor analysis. Reliability was measured by intra-class correlation coefficient and internal consistency. Since the items 12 (snoring) and 16 (thrush) failed to obtain the minimum principal axis factoring in exploratory factor analysis, they were removed from the Persian version. Confirmatory factor analysis showed a good fit for the extracted model. Cronbach’s alpha was .94 for the frequency items and .95 for the limitation items. Intra-class correlation coefficient was between .58 and 1 for frequency items and between .73 and 1 for limitation items. The Persian version of pregnancy symptoms inventory was a valid and reliable scale to be used for Iranian pregnant women.

ABSTRACT Evaluation of physician practice is necessary, both to provide feedback for self-improvement and to guide department heads during yearly evaluations. Objective: To develop and implement a peer-based performance evaluation tool and to measure reliability and physician satisfaction. Methods: Each emergency physician in an urban emergency department evaluated their peers by completing a survey consisting of 21 questions on effectiveness in 4 categories: clinical practice, interaction with coworkers and the public, nonclinical departmental responsibilities, and academic activities. A sample of emergency nurses evaluated each emergency physician on a subset of 5 of the questions. Factor analysis was used to assess the reliability of the questions and categories. Intra-class correlation coefficients were calculated to determine inter-rater reliability. After receiving their peer evaluations, each physician rated the process’s usefulness to the individual and the department. Results: 225 surveys were completed on 16 physicians. Factor analysis did not distinguish the nonclinical and academic categories as distinct; therefore, the survey questions fell into 3 domains, rather than the 4 hypothesized. The overall intra-class correlation coefficient was 0.43 for emergency physicians, indicating moderate, but far from perfect, agreement. This suggests that variability exists between physician evaluators, and that multiple reviewers are probably required to provide a balanced physician evaluation. The intra-class correlation coefficient for emergency nurses was 0.11, suggesting poor reliability. Overall, 11 of 15 physicians reported the process valuable or mostly valuable, 3 of 15 were unsure and 1 of 15 reported that the process was definitely not valuable. Conclusion: Physician evaluation by a single individual is probably unreliable. A useful physician peer evaluation tool can be developed. Most physicians view a personalized, broad-based, confidential peer review as valuable.

Abstract Purpose (main purposes and research question) The purpose of this study is to assess the accuracy and precision of the smartphone with application and casing (Scolioscreen) compared to the Scoliometer. Methods The Axial Trunk Rotation (ATR) was measured in adolescent scoliosis patients visiting the outpatient clinic while performing the Adam Forward Bending Test. The Scolioscreen measurements were performed by the orthopedic surgeon and a parent. They were compared to the measurement with the Scoliometer by the orthopedic surgeon, the gold standard. The accuracy was determined with the Pearson’s correlation coefficient, and precision was determined by assessing the intra- and inter-variability with the intra-class correlation coefficient (ICC). Results Fifty patients with adolescent idiopathic scoliosis (44 girls) were included with a mean age of 14.1 years and a mean Cobb angle of 38.5°. The accuracy of both the parents and orthopedic surgeon was excellent with a Pearson correlation coefficient of 0.92 and 0.97, respectively. All the ICC’s, both intra- and inter-observer, were over 0.92 demonstrating excellent precision. Conclusion This study confirms the accuracy and precision of the Scolioscreen when measuring the ATR on patients with AIS. Therefore, the Scoliometer can be replaced by the more easily available Scolioscreen which can be used by both physician and parents.

Abstract Background The purpose of this retrospective study was to evaluate cylinder axis agreement between manifest refraction (MR), cycloplegic refraction (CR), Allegro Oculyzer ІІ and Allegro Topolyzer-Vario. Methods We included 82 patients (32 males and 50 females, 28.1 ± 8.7 years old), with 156 eyes scheduled for wavefront optimized laser refractive surgery, photorefractive keratectomy (PRK) in 50 eyes and laser- assisted in situ keratomileusis (LASIK) in 106 eyes, for correction of simple, myopic, hyperopic or mixed astigmatism. Cylinder axis was determined under manifest and cycloplegic refractions and using Allegro Occulyzer ІІ and Allegro Topolyzer-Vario platforms. Cylinder axis agreement was assessed by Intra class Correlation coefficient, Pearson Correlation coefficient and by the method described by Bland and Altman. Results Intra class Correlation Coefficient and Pearson Correlation Coefficient showed statistically significant cylinder axis agreement between manifest refraction, cycloplegic refraction, Allegro Oculyzer ІІ and Allegro Topolyzer-Vario (p <0.001*). Despite statistically significant cylinder axis agreement between the four measuring tools, 4 of 156 eyes (2.5%) showed unexpected discrepancy between Allegro Oculyzer ІІ and Allegro Topolyzer-Vario cylinder axis. Conclusions Although cylinder axis shows statistically significant agreement between manifest refraction, cycloplegic refraction, Allegro Oculyzer ІІ and Allegro Topolyzer-Vario, unexpected discrepancies occur.

Smallest Detectable Change

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.

To make the Japanese version of the CESD-R—a revised version of the Center for Epidemiologic Studies depression scale (CES-D)—in the assessment of depressive symptoms in a general population. The English version of CESD-R was translated into Japanese, and back-translated into English by three native speakers of Japanese and English; then, we selected the version most completely consistent with the original items. The CESD-R was applied to 398 community-dwelling people (191 men: 48.0%, and 207 women: 52.0%) who were over 40 years old. The Japanese version of the CES-D was also carried out in the same population. Factor analysis was performed. Additionally, the correlations between the CESD-R and CES-D results were identified. The CESD-R scores showed a significantly positive correlation with CES-D scores (r = 0.74, p < 0.0005). Analysis of the CESD-R yielded a Cronbach’s alpha result of 0.90. Factor analysis revealed one principal factor in the CESD-R, whereas the original CES-D had two factors because of reversed items. The Japanese version of the CESD-R appears to have the reliability to be applicable for assessing depressive symptoms in population-based samples. However, because the Japanese expressions for some items might be unusual, our study population was also limited; further studies on other populations and on incorporating improved Japanese terminology will be needed.

Improvement in rider mobility represents an important functional gain for people with disabilities undergoing hippotherapy. However, there is no validated measuring instrument to track and document the rider's progress in riding activities. In this study, we aimed to develop and establish validity evidence for an instrument to assess hippotherapy participants’ mobility on horseback. We report on this development through the stages of: (a) content validation, (b) construct validation, (c) inter- and intra-rater reliability and (d) internal consistency analysis. We evaluated its factor structure with exploratory factor analyses, calculated values for inter- and intra-rater reliability using the intra-class correlation coefficient, and calculated its internal consistency using Cronbach's alpha. We followed recommendations by the Guidelines for Reporting Reliability and Agreement Studies. We found good inter-rater reliability (intra-class correlation coefficient – ICC = 0.991–0.999) and good intra-rater reliability (ICC = 0.997–1.0), and there was excellent internal consistency (Cronbach's α = 0.937–0.999). The instrument’s factor structure grouped its three domains into one factor. As this instrument is theoretically consistent and has been found to be appropriate and reliable for its intended use, it is now available for the measurement of horseback mobility among hippotherapy riders.

Loneliness is usually a chronic condition which may lead to physical and psychological undesirable consequences, and requires measurement and intervention. This study was conducted with the aim of preparing a Persian version of the 11-item de Jong Gierveld Loneliness Scale and evaluating its psychometric properties among the Iranian older adults. After applying the translation-back translation method, the prepared script was subjected to the face and content validity evaluations and a Persian version of the scale was prepared. Factor analysis, concurrent validity, internal consistency, and test-retest methods were used to validate the scale. The Persian version of the 11-item de Jong Gierveld Loneliness Scale showed acceptable content validity. The negative and significant correlations between the loneliness scores and the Philadelphia Geriatric Center Morale Scale indicated that the questionnaire had acceptable concurrent validity. The results of confirmatory factor analysis confirmed two factors for the scale. Also, the results of the intra-class correlation coefficient and Cronbach’s alpha coefficient demonstrated that the scale had acceptable reliability. The Persian version of the 11-item de Jong Gierveld Loneliness Scale is an appropriate tool for measuring loneliness in the Iranian older adults.

Katz and Stirrat devised a hand diagram, which uses subjective information from the patient for the diagnosis of carpal tunnel syndrome (CTS). They reported a good result. We tested the inter-observer and intra-observer reliability of this hand diagram. Twenty five consecutive patients with a diagnosis of CTS, 25 with other common hand and wrist problems but CTS and 25 healthy individuals were prospectively recruited. Each patient filled in a hand diagram. Two experienced hand surgeon scored the diagrams blindly on two different sittings four-week apart. The intra-class correlation coefficient (ICC) and Cohen's Kappa were used for intra and inter-observer reliability respectively. The intra-observer agreement was poor (ICC 95% 0.33–0.65) and inter-observer was fair (Kappa = 0.241). This study does not support the use of Katz and Stirrat Hand Diagram for the diagnosis of carpal tunnel syndrome in place if a thorough clinical examination.
