Objective To primarily test the reliability and validity of the Kashin-Beck Disease (KBD) affected big joints function assessing system for adult Tibetans in Rangtang County. Method From June to July 2009, 142 KBD patients were investigated with the function assessing system in Rangtang County of Ngawa. Cronbach’s α coefficient was calculated to estimate internal consistency reliability. Pearson’s r for the correlation of the items with the total score of the scale was computed to test the internal validity. Principal component factor analysis with varimax rotation analysis was conducted to explore construct validity. Result Both the response and complete rates of the scale were 100%. The time for completing the scale was 7.8±3.4 minutes. Cronbach’s α was 0.857, which revealed satisfactory internal consistency reliability. Pearson correlation analysis revealed significant correlation between the scores of each item and the total score of the scale (Plt;0.05). Pearson’s r value of each item was more than 0.4, only except the items of “sitting with legs crossed” and “standing at attention”. The principal factor analysis extracted three latent factors explaining 68.1% of the variation together. The latent factors weights of the items were over 0.4 except the items of “standing at attention”, "taking food” and “wiping after defecation”. Conclusion The reliability and validity of KBD affected big joints function assessing system for adult Tibetans in Rangtang County was good in this primary test, the function assessing system has to be widely applied and further assessed among Tibetans suffered with KBD, in order to provide a standard evaluation criterion in KBD integrate control.

ObjectiveThe purpose of this study was to translate the U-CEP scale into Chinese, and evaluate the reliability and validity of the Chinese version of the U-CEP, in order to provide a measurement and evaluation tool for clinical epidemiology education and research. MethodsThe U-CEP scale was translated and adapted using the Brislin translation model. A nationwide survey of clinicians was conducted using the Chinese version of the U-CEP. Item analysis, reliability analysis, and validity analysis were performed using SPSS 26.0 software. ResultsThe discriminant validity analysis showed that except for item 4, the critical value (CR) of the other twenty-four items differed significantly between high and low groups (P<0.01), with CR values ranging from 2.902 to 14.609. The ITCs of the 25 items were all positive, with 5 items having an ITC<0.15(20%), 2 items having ITC≥0.15~0.20 (8%), 6 items having ITC≥0.20~0.40 (24%) and 12 items having ITC≥0.40 (48%). In terms of reliability, the overall Cronbach’s α coefficient of the Chinese version of the U-CEP was 0.80, with Cronbach’s α coefficient ranging from 0.752 to 0.805 when deleting each item one by one. The test-retest reliability was 0.848 (P<0.001). The alternative-form reliability was 0.838 (P<0.001). In terms of validity, expert analysis showed that the content validity of the Chinese version of the U-CEP was good. The construct validity analysis showed that the cumulative contribution rate of the 25 items was 57.50%. No respondent scored full marks or zero marks, indicating that no ceiling or floor effects were found. There were statistically significant differences in the total scores among clinicians with different educational backgrounds or with or without systematic learning of relevant knowledge (P<0.05). ConclusionThe Chinese version of the U-CEP has good reliability and validity, as well as good cultural adaptability. It can effectively assess a physician's knowledge of clinical epidemiology.
ObjectivesThis study aimed to evaluate the validity and reliability of the clinical practice guidelines (CPGs) applicability evaluation tool, a preliminary revised tool, by using it to appraise specific clinical guidelines.MethodsMedical staffs were sampled from relevant departments in domestic medical institutions to use tool to evaluate the two guidelines. Spearman-Brown coefficient of odd-even split-half method and Cronbach's alpha coefficient were used to evaluate the split-half reliability and internal consistency reliability. The convergent and discriminant validity were evaluated by correlation analysis and correlation coefficient comparison hypothesis test, and the structural validity was investigated by confirmatory factor analysis based on structural equation.ResultsThe split-half reliability of the evaluation tool was 0.86, and the Cronbach's coefficient of the whole tool and each dimension were greater than 0.7 for two guidelines. The success rates of tool convergent and discriminant validity calibration were 100%. In the second-order confirmatory factor analysis model, the χ2 and df were 3.38 and 2.46, the comparative fit index (CFI) were 0.872 and 0.974, the goodness of fit index (GFI) were 0.954 and 0.983, and the adjusted goodness of fit index (AGFI) were 0.846 and 0.959 for two guidelines respectively. Both standard root mean square residual (SRMR) and root mean square error of approximation (RMSEA) were less than 0.09. Both P values of RMSEA hypothesis test were greater than 0.05.ConclusionsThe evaluation scale is a valid and reliable instrument for assessing the applicability of CPGs, which should be further evaluated in practical applications in the future.
ObjectiveTo compare and evaluate the discrimination, validity, and reliability of different data envelopment analysis (DEA) models for measuring the effectiveness of models by selecting different input and output indicators of the model.MethodsData from health statistical reports and pilot program of diagnosis-related groups of tertiary hospitals in Hubei Province from 2017 to 2018 were used to analyze the discrimination, content and structure validity, and reliability of the models. Six DEA models were established by enriching the details of input and output on the basis of the input and output indicators of the conventional DEA model of hospitals.ResultsFrom the view of discrimination, the results of all models were left-skewed, the cost-efficiency model had the lowest left-skewed degree (skewness coefficient: -0.14) and was the flattest (kurtosis coefficient: -1.02). From the view of structure validity, the results of the cost-efficiency model were positively correlated with total weights, outpatient visits, and inpatient visits (r=0.328, 0.329, 0.315; P<0.05). From the perspective of content validity, the interpretation of model was more consistent with theory of production after revision of input and output indicators. From the view of reliability, the cost efficiency model had the largest correlation coefficient between the data of 2017 and 2018 (r=0.880, P<0.05).ConclusionsAfter refining the input and output indicators of the DEA model, the discrimination, validity, and reliability of the model are higher, and the results are more reasonable. Using indicators such as discrimination, validity, and reliability can measure the effectiveness of the DEA model, and then optimize the model by selecting different input and output indicators.
ObjectiveTo conduct meta-analysis with the reliability of objective structured clinical examination (OSCE), so as to the reliability of OSCE used in the tests for evaluating clinical capacities of medical students. MethodsArticles about evaluating clinical capacities of medical students using OSCE and using comprehensive coefficient of Cronbach's α to measure the reliability of OSCE were electronically searched in PubMed, ScienceDirect, CNKI, WanFang data and VIP from Jan. 1998 to May. 2013. Two reviewers screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of the included studies. Then meta-analysis was performed using SSPS 17.0 software. ResultsThirty-four studies involving 53 coefficients of Cronbach's α were included, of which, there were 18 articles written in English involving 28 coefficients of Cronbach's α and 16 articles written in Chinese involving 25 coefficients of Cronbach's α. The results of meta-analysis showed that:the total coefficient of Cronbach's α of OSCE was 0.700 (95%CI 0.660 to 0.737). The coefficient of Cronbach's α of internationally-published literature was 0.745 (95%CI 0.696 to 0.790) and that of nationally-published literature was 0.648 (95%CI 0.584 to 0.705), with a significant difference between two groups. ConclusionCurrently, the reliability of internationally/nationally-used OSCE is 0.7, which has relatively better reliability when used in the tests for evaluating clinical capacities of medical students at home and aboard. However, the reliability of OSCE at abroad is fairly better than that at home.
