ABSTRACT
Objective To choose a better version of Rivermead Behavioral Memory Test(RBMT)to assess memory function of patients with mild traumatic brain injury(TBI).Methods From April,2015 to Febrary,2017,40 mild TBI patients and 40 healthy people were re-cruited as TBI group and control group respectively.Both groups completed the Chinese version of RBMT-II first,and 24 hours to 48 hours later,completed the Chinese version of RBMT-III.The raw score of each test and the number of perfect scores and floor performance were scored and compared.Results Compared with the control group,TBI group got lower scores in six subtests of RBMT-II(F>2.131,P<0.05) and twelve subtests of RBMT-III(F>2.035,P<0.05).Administration of the RBMT-III resulted in less participants performing at or near indi-vidual subtest's ceiling than RBMT-II,mainly in the picture recognition,face recognition,the line instant memories,the line delay memo-ries,letters delayed recall and orientation date(Z>2.117,P<0.05).Also administration of the RBMT-III resulted in less floor performance than those of RBMT-II,mainly in remembering the name and the appointment(Z>2.138,P<0.05).Conclusion RBMT-III has substantial im-provement over the original RBMT-II,as it reduces the problem of ceiling and floor performance and the number of misclassifications.
ABSTRACT
Objective To evaluate the reliability and validity of SF-36 in patients with advanced schistosomiasis,so as to proride scientific basis for the selection of suitable tools for health measure.Methods A Chinese version of SF-36 scale was applied to evaluate the health of patients with advanced schistosomiasis by a household survey in Hanshou County of Hunan Province and Jiangling County of Hubei Province,then the reliability and validity of the scale were tested.Results Atotal of 326 patients were investigated in the two counties.The split-half reliability(with a split-half coefficient of 0.95) and the internal consistency (Cronbach'α coefficients of the eight dimensions ranged from 0.86 to 0.88)were satisfying;the convergent and discriminative validity were high with the test successful rates of 97.14%and 87.86%,respectively;the criterion validity was acceptable with a correlation coefficient between the total score of SF-36 and EQ-5D+C VAS score of 0.70.However,the construct validity seemed to be not so reasonable as only 2 dimensions out of 8 were completely in accordance with the theoretical model on factor loading.The percentages of floor effect and ceiling effect in most dimensions were not significant except RP and RE(with the percentages of floor effect of 50.31%and 48.16%,respectively).Conclusions SF-36 is appropriate to be used in patients with advanced schistosomiasis.but some items need to be improved according to the local settings of endemic areas.
ABSTRACT
OBJECTIVE: To develop a new scoring system for Jebsen Hand Function Test (JHFT) and test validity of the new score scale in stroke patients. METHOD: JHFT and the modified Barthel index upper extremity subtest (MBI-U) were performed on a total of 210 stroke patients at a tertiary university hospital. Based on JHFT raw data, scores were calculated from the existing scoring system and the new one. Validity of scores from each system was evaluated by comparing each score with the MBI-U score. Floor effects of both scoring system were compared. RESULTS: In all the seven subtest items of JHFT, the floor effect of the new scoring system was far lower than that of the existing one. Pearson correlation coefficient between the score from the new scoring system and the MBI-U score was 0.4880 (p<0.0001, n=210). CONCLUSION: 'New score scale' -a scoring system for JHFT based upon new criteria- was presented. New score scale for JHFT has reduced floor effect and is valid in stroke patients.
