Validity and reliability of the Polish version of the Michigan Neuropathy Screening Instrument

BACKGROUND Diabetic sensorimotor polyneuropathy is an important risk factor for foot ulceration and amputation.Thus,patients with diabetes should be screened for this disorder according to local guidelines.An obstacle to the diagnosis of this disease may be the lack of unified diagnostic criteria due to the lack of properly validated scales used for assessment.AIM To validate both sections(A and B)of the Michigan Neuropathy Screening Instrument(MNSI)in Polish(PL)patients with diabetes.METHODS A cross-sectional study using a test(A1,B1)and re-test(A2,B2)formula was performed in 80 patients with diabetes.The gold standard used for neuropathy detection was a nerve conduction study(NCS)which was performed in all participants.Reliability of the MNSI-PL was assessed using the Cronbach’s alpha,Kuder-Richardson formula 20(KR-20),split-half reliability,the Gottman split-half tests,and correlation between first and second half was accessed.Stability was assessed using an intraclass correlation coefficient(ICC).For external validation,we used simple linear correlation,binomial regression,and agreement between two different tools using a Bland-Altman plot analysis.RESULTS The scale was internally consistent(Cronbach’s alpha for the full scale:0.81 for A and 0.87 for B).MNSI-PL scores in test/retest showed high stability(ICC=0.73 for A and ICC=0.97 for B).The statistically important correlations between MNSI-PL and NCS were found for B1,B2,and A1(P<0.005).The cut-off points of≥3 for section A(sensitivity of 90%-100%;specificity of 33%-40%)and≥2 for section B(sensitivity of 81%-84%;specificity of 60%-70%)were obtained during neuropathy detection.CONCLUSION The MNSI-PL is a reliable and valid instrument in screening for diabetic neuropathy.

Reliability and validity of the hidden hunger assessment scale in China-revised for high school students

Objective:Hidden hunger remains a severe public health problem that affects millions of people worldwide.In China,challenges related to dietary imbalance and hidden hunger persist.Micronutrient inadequacy deserves more attention among adolescents,given its vital role in their growth and development;however,this problem appears to have been largely ignored.High school students,in particular,are often at a high risk of hidden hunger but have limited assessment tools available.Therefore,this study aims to revise the hidden hunger assessment scale for high school students(HHAS-HSS)in China and assess its reliability and validity.Methods:Based on a literature review,expert consultation,pre-experiment,and formal survey,a hidden hunger assessment scale was revised for high school students.The formal survey involved 9336 high school students in 11 of the 16 cities in Anhui Province,China,and 9038 valid questionnaires were collected and included in the analysis.The item analysis,internal consistency reliability,test-retest reliability,content validity,exploratory factor analysis,and confirmatory factor analysis of the HHAS-HSS were examined.Results:The HHAS-HSS included a total of 4 dimensions and 12 items:"vegetables and food diversity"(three items),"fruits and dairy products"(three items),"micronutrient-dense foods"(four items),and"health condition and eating habits"(two items).The results showed a Cronbach's alpha of 0.758,a split-half reliability of 0.829,and a test-retest reliability of o.793,indicating good internal consistency.Using the Bartlett's test and Kaiser-Meyer-Olkin test(KMO)to test the exploratory factor analysis presented a four-factor model of the HHAS-HSS,the KMO0 value was 0.820(P<0.001),which indicated the possibility for factor confirmatory factor analysis.Using the maximum variance rotation method,four factors were obtained,and the cumulative variance explained rate was 57.974%.Confirmatory factor analysis also supported the division of the scale into four dimensions,and the fitting indices were x^(2)=1417.656,x^(2)/df=29.534,goodness-of-fit index=0.974,adjusted goodnessof-fit index=0.958,parsimonious goodness-of-fit index=0.600,normed fit index=0.938,incremental fit index=0.940,Tucker-Lewis index=0.917,comparative fit index=0.939,and root mean square error of approximation=0.056.Except for x^(2)/df,all the indices reached the fitting standard,and the above results showed that the construct validity of the scale reached an acceptable level.Conclusions:The HHAS-HSS has good validity and reliability for Chinese high school students.It is a convenient self-report measure of hidden hunger risk.

Validity and Reliability of the Preference for and Tolerance of the Intensity of Exercise Questionnaire among Chinese College Students

The rising prevalence of physical inactivity is in all age groups(e.g.,in college students)a major public health issue as not meeting the recommended minimum amount of regular physical activity is linked to adverse health events.Vice versa,there is mounting evidence that achieving the recommended amount of regular physical activity is a vital element to prevent chronic diseases,but there is often an insufficient adherence to planned and structured forms of physical activity(i.e.,physical exercises).In this context,there is a large body of evidence indicating that exercise adherence is,among other factors,influenced by exercise-related affective responses.The Preference for and Tolerance of the Intensity of Exer-cise Questionnaire(PRETIE-Q)has been developed to measure these affective responses(e.g.,to specific exercise inten-sities).So far,no validated Chinese version of the PRETIE-Q has been available in the literature.To address this gap in literature,the present study developed and validated a Chinese version of the PRETIE-Q in a large sample of Chinese college students.Data from a total of 1117 college students were collected for analyses concerning factorial validity and construct validity.The re-test reliability was established using a sample of 150 randomly selected participants.In addition,the level of regular physical activity(PA),cardiorespiratoryfitness(CRF),and resilience were used to examine possible links with two domains(preference and tolerance)of the PRETIE-Q.Our results showed that a Chinese version of the PRETIE-Q has a goodfit and reliability(Cronbach’sαof 0.72 to 0.85 for preference and tolerance,respectively;ICC:r=0.72 of preference and r=0.67 of tolerance;fit indices:χ^(2)=21.612,df=19,p>0.05,TLI=0.997,CFI=0.998,RMSEA=0.016,SRMR=0.024).Secondly,positive associations of intensity-tolerance with PA,CRF,and resilience were observed.In summary,this study indicates that the Chinese version of the PRETIE-Q has sound psychometric properties and can be used in Chinese college students.The adapted version of the PRETIE-Q paves the way for further research on exer-cise-related affective responses in Chinese-speaking samples,although the generalizability of ourfindings needs to be established for other cohorts such as adolescents and older people with and without chronic diseases.

Validity and Reliability of Chinese Physical Activity Questionnaire for Children Aged 10-17 Years

Objective This study is aimed to report the development,the reliability and validity of the Chinese Children Physical Activity Questionnaire(CCPAQ)which was designed for the assessment of physical activity pattern in young population in China.Methods The CCPAQ was administered for two times in 119 children(mean age 13.1±2.4 years;boys 47%)to examine reliability by using intraclass correlation coefficients.Validity was determined in 106 participants by agreement with the CCPAQ measures and the objective method,the ActiGraph accelerometer.Data on physical activity patter n including time spe nt on d iff ere nt intensi ties and total physical activity,sedentary behavior as well as physical activity energy expenditure were used to assess the validity with Spearman's correlation coefficient and the Bland-Altman plots.Results The reliability coefficient of the CCPAQ ranged from 0.63-0.93(Intra-class correlation coefficient).Spearman's correlation coefficient for validity of time spent on total physical activity and sedentary behavior were all 0.32(P<0.001),and for physical activity energy expenditure was 0.58(P<0.001).Time spent on moderate-to-vigorous physical activity and light physical activity showed a relatively low correlation with the accelerometer(rho=0.20,P=0.040;rho=0.19,P=0.054).Conclusion The CCPAQ appears to be a promising and feasible method to assess physical activity pattern in Chinese children.

Food Frequency Questionnaire for Chinese Children Aged 12-17 Years: Validity and Reliability

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.

Validity and reliability of Chinese version of Fatigue Impact Scale in cerebral infarction patients

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.

Validity and reliability of the Ocular Motor Nerve Palsy Scale

Objective and accurate assessment of the degree of ocular motor nerve palsy is helpful not only in the evaluation of prognosis, but also for the screening of treatment methods. However, there is currently no comprehensive measure of its severity. In this study, we designed the Ocular Motor Nerve Palsy Scale and investigated its validity and reliability. Six experts were invited to grade and evaluate the scale. The study recruited 106 patients with a definite diagnosis of unilateral isolated ocular motor nerve palsy. Three physicians evaluated the patients using the scale. One of the three physicians evaluated the patients again after 24 hours. The content validity index（CVI） and factor analysis were used to analyze the scale＇s construct validity. The intraclass correlation coefficient and Cronbach＇s alpha were used to evaluate the inter-rater and test-retest reliability and the internal consistency. The CVI results（I-CVI = 1.0, S-CVI = 0.9, Pc = 0.016, K＊ = 1） indicated good content validity. Factor analysis extracted two common factors that accounted for 85.2% of the variance. Furthermore, the load value of each component was above 0.8, indicating good construct validity. The Ocular Motor Nerve Palsy Scale was found to be highly reliable, with an inter-rater reliability intraclass correlation coefficient of 0.965（P 0.01）, a test-retest reliability intraclass correlation coefficient of 0.976（P 0.01）, and Cronbach＇s alpha values of 0.63–0.70. In conclusion, the Ocular Motor Nerve Palsy Scale with good validity and reliability can be used to quantify the severity of ocular motor nerve palsy. This study was registered at Chinese Clinical Trial Registry（registration number： Chi CTR-OOC-17010702）.

Methods One hundred and eighty-six heroin addicts （144 men and 42 women） receivihg MMT at three clinics in Guizhou province, southwest China, were recmited. They were all interviewed with a questionnaire of ASI-C-5 and 35 were re-interviewed at an interval of seven days to assess its test-retest reliability. Results Cronbach＇s alpha for internal consistency of CSs varied from 0.60 to 0.81 in all domains. Test-retest reliability of composite scores （CSs） of ASI-C-5 were satisfactory （r=0.38-0.97）. Based on item analysis and expert＇s suggestions, five items were deleted and one item was modified in ASI-C-5. Criterion validity of ASI-C-5 was found acceptable, as compared to addicts＇ self-rating anxiety scale （SAS） and self-rating depression scale （SDS） （r=0.59 and 0.45） except for social support rating scale （SSRS）. Conclusions ASI-C-5 can be used for heroin addicts receiving MMT with acceptable reliability and validity.

Cronbach's a reliability, concurrent validity, and factorial structure of the Death Depression Scale in an Iranian hospital staff sample

Objective: Death depression is an important component in the process of death and dying. Death depression is the second element of death. Depression is one of the important features in death distress. The aim of this study was to explore the performance of the Farsi version of the Death Depression Scale with an Iranian convenience sample of nurses (n =106).Methods: Nurses were selected using a convenience sampling method, and completed the Death Depression Scale (DDS), Death Concern Scale (DCS), Collett-Lester Fear of Death Scale (CLFDS), Reasons for Death Fear Scale (RDFS), Templer's Death Anxiety Scale (DAS), and Death Obsession Scale (DOS). Results: The results of exploratory factor analysis on DDS identified 4 factors (56.16%of variance). Factor 1 labeled"Death sadness", Factor 2 labeled"Death finality/end and Death dread/fear", Factor 3 labeled"Death despair and Death depression", and Factor 4 labeled"Death loneliness". Cronbach's a coefficient was 0.84, Spearman-Brown coefficient 0.85, and Guttman Split-Half coefficient 0.81 The DDS correlated 0.40 with the DCS, 0.39 with the CLFDS, 0.50 with the DAS, 0.35 with the RDFS, and 0.44 with the DOS, indicating good construct and criterion-related validity. Concurrent validity for the DDS with the other scales were significant. Conclusions: The DDS has good validity and reliability, and it can use in clinical and research settings.

Purpose:The purpose of this study was to assess the applicability of the Chinese version of Cognitive Appraisal of Health Scale(CAHS)for renal transplant recipients,and to make a preliminary evaluation of its reliability and validity.Methods:A total of 147 renal transplant recipients who attended a transplant follow-up clinic in a Level 3,Grade A hospital in Beijing were asked to complete the Chinese version of CAHS.Following completion the reliability and validity of the scale were tested.Results:The Cronbach alpha coefficient of Chinese version of CAHS among subscales of threat,harm,challenge and benign-irrelevant were 0.857,0.806,0.680,0.100 respectively;and the test-retest reliability coefficient were 0.791,0.601,0.624,0.470(p<0.01).Spearman correlation was used to test the four subscales'correlation between the item score and the total score,in which threat was 0.598e0.748,challenge was 0.517e0.651,harm was 0.528 e0.735 and benign-irrelevant was 0.507e0.651.These correlations were all statistically significant.The four common factors were extracted using factor analysis.The four factors accounted for 50.356%of the total variance.The SF-36 Physical Component Summary(PCS)and Mental Component Summary(MCS)scores were correlated with each subscale score in CAHS.Threat was weakly correlated to PCS,and was moderately correlated to MCS;harm was moderately correlated to both PCS and MCS;challenge was weakly correlated to both PCS and MCS and benign-irrelevant did not correlate with neither PCS nor MCS.The Chinese version of CAHS has been shown to have good discriminate and convergent validity.Conclusion:The Chinese version of the CAHS was supported to be applicable and to provide measurable performance in renal transplant recipients,thus it can be utilized with renal transplant recipients in China.

Reliability and concurrent validity of postural asymmetry measurement in adolescent idiopathic scoliosis

AIM To investigate the reliability and concurrent validity of the Baseline~? Body Level/Scoliosis meter for adolescent idiopathic scoliosis postural assessment in three anatomical planes.METHODS This is an observational reliability and concurrent validity study of adolescent referrals to the Orthopaedic department for scoliosis screening at KarolinskaUniversity Hospital, Stockholm, Sweden between MarchMay 2012. A total of 31 adolescents with idiopathic scoliosis(13.6 ± 0.6 years old) of mild-moderate curvatures(25°± 12°) were consecutively recruited. Measurement of cervical, thoracic and lumbar curvatures, pelvic and shoulder tilt, and axial thoracic rotation(ATR) were performed by two trained physiotherapists in one day. The intraclass correlation coefficient(ICC) was used to determine the inter-examiner reliability(ICC2,1) and the intra-rater reliability(ICC3,3) of the Baseline~? Body Level/Scoliosis meter. Spearman's correlation analyses were used to estimate concurrent validity between the Baseline~? Body Level/Scoliosis meter and Gold Standard Cobb angles from radiographs and the Orthopaedic Systems Inc. Scoliometer.RESULTS There was excellent reliability between examiners for thoracic kyphosis(ICC2,1 = 0.94), ATR(ICC2,1 = 0.92) and lumbar lordosis(ICC2,1 = 0.79). There was adequate reliability between examiners for cervical lordosis(ICC2,1 = 0.51), however poor reliability for pelvic and shoulder tilt. Both devices were reproducible in the measurement of ATR when repeated by one examiner(ICC3,3 0.98-1.00). The device had a good correlation with the Scoliometer(rho = 0.78). When compared with Cobb angle from radiographs, there was a moderate correlation for ATR(rho = 0.627).CONCLUSION The Baseline~? Body Level/Scoliosis meter provides reliable transverse and sagittal cervical, thoracic and lumbar measurements and valid transverse plan measurements of mild-moderate scoliosis deformity.
