This was a cross sectional study of Lusaka school children （n = 420） aged 11-15 years using the self-report SDQ-Y and a demographic questionnaire. It was found that compared to a UK normative sample, Zambian adolescents were almost twice as likely to have total difficulties scores in the abnormal range （O.R. 1.9）. It was found that there was a significant difference in the total SDQ scores （Z = -2.67, P = 0.008） with children reporting health problems having significantly higher scores. Children reporting health problems also had significantly more emotional problems （Z = -2.78, P = 0.005）. There was a trend for children with health problems to score higher on the hyperactivity scale （Z = -1.9 P = 0.053）. The internal consistency of SDQ subscales ranged from low to moderate. It can be concluded that SDQ is a useful instrument for use with Zambian adolescents, in particular, the total difficulties score and the emotional difficulties score performed well in this sample and could potentially be used to screen for mental health problems or to examine the impact of interventions.展开更多

We aimed to assess the Chinese (mainland) version of the PDQ-39. Seventy-one subjects with Parkinson's disease (PD) completed the PDQ-39 and the Medical Outcomes Study 36-item Short Form Health Survey (SF-36). All subjects were retested with the PDQ-39 a week later. The united Parkinson's disease rating scale (UPDRS) and the Hoehn and Yahr (H & Y) scale were also used to evaluate the subjects. Reliability was assessed by Cron- bach's α and intra-class correlation coefficient (ICC). Validity was examined in terms of agreement with SF-36, UPDRS, and H & Y scales. The Chinese (mainland) version of the PDQ-39 demonstrated acceptable reliability (Cronbach's α: 0.84-0.88; ICC: 0.56-0.82). The item-total correlations (0.33-0.88) and scaling success rates (77.56%) indicated satisfactory convergent and discriminant validity of the PDQ-39 items. The correlations between related constructs of the PDQ-39 and UPDRS (r=0.44-0.68) and between those of the PDQ-39 and SF-36 (r=(-0.46)-(-0.69)) were all statistically significant (P<0.01). Except for stigma, cognitions, and bodily discomfort, all other dimensions of the PDQ-39 significantly discriminated patients at different H & Y stages indicated by the H & Y scale. Although our observations indicate that some problematic subscales of this version of the PDQ-39 could be improved upon, this study suggests acceptable reliability and validity of the Chinese (mainland) version of the PDQ-39.展开更多

Methods A semi-quantitative 72-food item FFQ was developed for children aged 12-17 years. The reliability and validity of this FFQ were evaluated against 24-h dietary recalls(24 h DRs) to measure the consumption of foods and nutrients. We administered two FFQs and three DRs to children(N = 160) over a period of 1 month to evaluate the reliability and validity. Reliability was examined by quartile agreement and intraclass correlation coefficients(ICCs), and validity was examined by quartile agreement, Bland-Altman plots and correlation with DRs. Results For reliability, the ICCs between the two FFQs ranged from 0.21 to 0.76 for foods and nutrients, and the quartile agreement ranged from 70.0% to 95.0% in the same or adjacent quartiles. Spearman’s correlation coefficients of foods and nutrients between the second FFQ and the 24 h DRs ranged from-0.04 to 0.59. The Bland-Altman plots demonstrated good agreement across the range of intakes among nutrients. The quartile agreement ranged from 50.0% to 100.0%, with infrequent misclassification. Conclusion The FFQ assessment of dietary intakes demonstrated acceptable relative validity and high reproducibility for Chinese children aged 12-17 years.展开更多

Three evaluation scales are available, including the Fatigue Impact Scale （FIS）. Yet none of these has been proven to be of use in the evaluation of psychological quality after post-stroke fatigue. OBJECTIVE： To introduce FIS into China, and to evaluate the validity and reliability of the Chinese Version in patients with cerebral infarction. DESIGN： Scale evaluation. SETTING： Department of Rehabilitation, Beijing Friendship Hospital, Capital Medical University. PARTICIPANTS： A total of 330 patients with cerebral infarction were selected from the Department of Neurology, Beijing Friendship Hospital, Capital Medical University from June 2005 to December 2006. All patients met diagnostic standards from the Fourth National Cerebrovascular Disease Academic Meeting of China Medical Association and were diagnosed with CT or MRI examination. Patients who were not willing to accept scale evaluation were excluded. METHODS： The English version of FIS was translated into Chinese and subsequently translated back to English again. FIS was given to the discharged patients, and they returned them upon completion. In-patients completed and immediately returned the FIS. Validity and reliability of the retrieved scales were ascertained with descriptive and inference analysis. MAIN OUTCOME MEASURES： Total scores and subscale scores of FIS. RESULTS： Out of 330 questionnaires, 214 valid questionnaires were deemed valid in total. Six components were extracted in factor analysis, and the total cumulative contribution was 73.919%, which suggested the questionnaire was valid. After correlation analysis, 6 components were divided into 3 subscales, including cognitive, physical, and social, which was the same as the English version. The Cronbach α value for the three subscales was 0.937 7, 0.918 8, and 0.940 6, respectively （〉 0.7）. CONCLUSION： The reliability and validity of the Chinese version of FIS met with satisfaction and appeared to be adaptable to cerebral infarction patients in China.展开更多

The evolutions of different initial perturbations superposed on the nonlinearly stable and unstable basic flows are examined using the two-dimensional quasi-geostrophic models of double periodic-boundary condition and rigid boundary condition. The results indicate that the valid time period of TLM, during which TLM can be utilized to approximate NLM with given accuracy, varies with the magnitudes of the perturbations and the nonlinear stability and instability of the basic flows. The larger the magnitude of the perturbation is, the shorter the valid time period. The more nonlinearly unstable the basic flow is, the shorter the valid time period of TLM. With the double—periodic condition the valid period of the TLM is shorter than that with the rigid—boundary condition. Key words Nonlinear stability and instability - Tangent linear model (TLM) - Validity This work was supported by the National Key Basic Research Project “Research on the Formation Mechanism and Prediction Theory of Severe Synoptic Disasters in China” (No.G1998040910) and the National Natural Science Foundation of China (No.49775262 and No.49823002).展开更多

文摘The 39-item Parkinson's Disease Questionnaire (PDQ-39) has been tested in many languages, but not in Chinese mainland. We aimed to assess the Chinese (mainland) version of the PDQ-39. Seventy-one subjects with Parkinson's disease (PD) completed the PDQ-39 and the Medical Outcomes Study 36-item Short Form Health Survey (SF-36). All subjects were retested with the PDQ-39 a week later. The united Parkinson's disease rating scale (UPDRS) and the Hoehn and Yahr (H & Y) scale were also used to evaluate the subjects. Reliability was assessed by Cron- bach's α and intra-class correlation coefficient (ICC). Validity was examined in terms of agreement with SF-36, UPDRS, and H & Y scales. The Chinese (mainland) version of the PDQ-39 demonstrated acceptable reliability (Cronbach's α: 0.84-0.88; ICC: 0.56-0.82). The item-total correlations (0.33-0.88) and scaling success rates (77.56%) indicated satisfactory convergent and discriminant validity of the PDQ-39 items. The correlations between related constructs of the PDQ-39 and UPDRS (r=0.44-0.68) and between those of the PDQ-39 and SF-36 (r=(-0.46)-(-0.69)) were all statistically significant (P<0.01). Except for stigma, cognitions, and bodily discomfort, all other dimensions of the PDQ-39 significantly discriminated patients at different H & Y stages indicated by the H & Y scale. Although our observations indicate that some problematic subscales of this version of the PDQ-39 could be improved upon, this study suggests acceptable reliability and validity of the Chinese (mainland) version of the PDQ-39.

文摘Objective The primary objective of this study was to examine the validity and reliability of a semi-quantitative food frequency questionnaire(FFQ) among Chinese children aged 12-17 years. Methods A semi-quantitative 72-food item FFQ was developed for children aged 12-17 years. The reliability and validity of this FFQ were evaluated against 24-h dietary recalls(24 h DRs) to measure the consumption of foods and nutrients. We administered two FFQs and three DRs to children(N = 160) over a period of 1 month to evaluate the reliability and validity. Reliability was examined by quartile agreement and intraclass correlation coefficients(ICCs), and validity was examined by quartile agreement, Bland-Altman plots and correlation with DRs. Results For reliability, the ICCs between the two FFQs ranged from 0.21 to 0.76 for foods and nutrients, and the quartile agreement ranged from 70.0% to 95.0% in the same or adjacent quartiles. Spearman’s correlation coefficients of foods and nutrients between the second FFQ and the 24 h DRs ranged from-0.04 to 0.59. The Bland-Altman plots demonstrated good agreement across the range of intakes among nutrients. The quartile agreement ranged from 50.0% to 100.0%, with infrequent misclassification. Conclusion The FFQ assessment of dietary intakes demonstrated acceptable relative validity and high reproducibility for Chinese children aged 12-17 years.
文摘BACKGROUND： Post-stroke fatigue has received much attention recently. Three evaluation scales are available, including the Fatigue Impact Scale （FIS）. Yet none of these has been proven to be of use in the evaluation of psychological quality after post-stroke fatigue. OBJECTIVE： To introduce FIS into China, and to evaluate the validity and reliability of the Chinese Version in patients with cerebral infarction. DESIGN： Scale evaluation. SETTING： Department of Rehabilitation, Beijing Friendship Hospital, Capital Medical University. PARTICIPANTS： A total of 330 patients with cerebral infarction were selected from the Department of Neurology, Beijing Friendship Hospital, Capital Medical University from June 2005 to December 2006. All patients met diagnostic standards from the Fourth National Cerebrovascular Disease Academic Meeting of China Medical Association and were diagnosed with CT or MRI examination. Patients who were not willing to accept scale evaluation were excluded. METHODS： The English version of FIS was translated into Chinese and subsequently translated back to English again. FIS was given to the discharged patients, and they returned them upon completion. In-patients completed and immediately returned the FIS. Validity and reliability of the retrieved scales were ascertained with descriptive and inference analysis. MAIN OUTCOME MEASURES： Total scores and subscale scores of FIS. RESULTS： Out of 330 questionnaires, 214 valid questionnaires were deemed valid in total. Six components were extracted in factor analysis, and the total cumulative contribution was 73.919%, which suggested the questionnaire was valid. After correlation analysis, 6 components were divided into 3 subscales, including cognitive, physical, and social, which was the same as the English version. The Cronbach α value for the three subscales was 0.937 7, 0.918 8, and 0.940 6, respectively （〉 0.7）. CONCLUSION： The reliability and validity of the Chinese version of FIS met with satisfaction and appeared to be adaptable to cerebral infarction patients in China.

文摘The impact of nonlinear stability and instability on the validity of tangent linear model (TLM) is investigated by comparing its results with those produced by the nonlinear model (NLM) with the identical initial perturbations. The evolutions of different initial perturbations superposed on the nonlinearly stable and unstable basic flows are examined using the two-dimensional quasi-geostrophic models of double periodic-boundary condition and rigid boundary condition. The results indicate that the valid time period of TLM, during which TLM can be utilized to approximate NLM with given accuracy, varies with the magnitudes of the perturbations and the nonlinear stability and instability of the basic flows. The larger the magnitude of the perturbation is, the shorter the valid time period. The more nonlinearly unstable the basic flow is, the shorter the valid time period of TLM. With the double—periodic condition the valid period of the TLM is shorter than that with the rigid—boundary condition.
