| Objective:To localize the English version of Multidimensional fatigue inventory(MFI),and to evaluate the reliability and validity of the Chinese version of MFI(C-MFI)in elderly ischemic stroke(IS)patients.To investigate the status of post-stroke fatigue(PSF)in elderly IS patients in China and to identify its influencing factors.Methods:Following the modified Brislin’s translation model and cross-cultural adaptation guideline,the original scale was translated,backtranslated,cross-cultural adapted and pre-tested after obtaining the authorization.A total of 205 elderly IS patients were investigated and evaluated using C-MFI at a tertiary hospital in Shenyang by convenience sampling method.The structural equation model was analyzed by using SPSS AMOS 24.0 software,the remaining data were statistically analyzed by using IBM SPSS Statistics 25.0 software.Pearson correlation coefficient,critical ratio,content validity index,structural validity index and Cronbach’sαcoefficient were used as the reliability and validity evaluation indicators of the C-MFI;General data of patients were described by using frequency and percentage;The status of PSF in elderly IS patients was described by using Mean and standard deviation;Univariate analysis and multiple stepwise regression analysis were used to investigate the influencing factors of PSF level in elderly IS patients(P<0.05,the difference was statistically significant).Results:1.Results of sinicization of the scale:(1)The structure of scale:The C-MFI consists of 20 items and five dimensions,including 5 items for physical fatigue dimension,4 items for mental fatigue dimension,4 items for reduced motivation dimension,3 items for reduced vitality dimension,and 3 items for general fatigue dimension.(2)The reliability and validity evaluation of scale:The correlation coefficients between the score of each item and the total score of the scale were 0.474～0.702,all>0.40,and the critical ratio values were 6.577～12.601,all>3.0,the differences were statistically significant(P<0.01).S-CVI/Ave was 0.99,S-CVI/AU was0.95,and I-CVIs were 0.80～1.00;The results of structure validity showed that KMO value was 0.867,and the Bartlett testχ~2value was 1807.285(df=190,P<0.001),five common factors were extracted from exploratory factor analysis,65.275%of the total variance was explained,and the number of common factors was consistent with the factor structure of the original scale,but different in the division of five items;The C-MFI was positively correlated with the Chinese version of Fatigue severity scale,r=0.554(P<0.001).The Cronbach’αcoefficients of each dimension were 0.664～0.839,and the Cronbach’sαcoefficient of the total scale was 0.889.2.Results of preliminary application of the scale:(1)The Current situation of PSF in elderly IS patients:Scores of 200 elderly IS patients’PSF were(63.80±14.05),which was generally at a moderately high level.(2)Univariate analysis results:the number of concurrent chronic diseases,pre-stroke exercise and the score of modified Rankin scale(m RS)had significant effects on the total score of PSF in elderly IS patients,with statistically significant differences(P<0.05).(3)Multivariate analysis results:the number of concurrent chronic diseases(β=0.138,P=0.026),pre-stroke exercise(β=0.211,P=0.001)and m RS score(β=0.459,P<0.001)were the influencing factors of PSF in elderly IS patients(P<0.05).The three factors could explain 27.7%of PSF variation of elderly IS patients.Conclusion:1.The C-MFI consists of 20 items,including 5 dimensions of physical fatigue,general fatigue,reduced vitality,reduced motivation and mental fatigue.The dimension categories are consistent with the original scale,and five items have been adjusted.The C-MFI has a good reliability and validity in elderly IS patients,which can well evaluate the PSF status of elderly IS patients in China.2.The PSF status of the elderly IS patients in China is at a moderately high level.Without exercise regularly before stroke,the more chronic diseases combined with stroke and the higher m RS score would lead to the exacerbation of fatigue symptoms,which are important influencing factors of PSF.It is suggested that medical staff should focus on early screening and evaluation,and carry out early management of PSF. |
