Objective:To test the reliability and validity of a multi-dimensional, quantitative video evaluation system (the Multi-dimensional system) for evaluating hand dysfunction among stroke survivors so as to provide an objective basis for its clinical application.Methods:Sixty stroke survivors with single dysfunctional hand were evaluated using the Multi-dimensional system and also using the Fugl-Meyer Upper Extremity Assessment (FMA-UE) and the Action Research Arm Test (ARAT) and in terms of their active range of hand motion (AROM-H). The Multi-dimensional system′s internal consistency, composite reliability, split-half reliability, parallel-forms reliability as well as intra- and inter-observer reliability were quantified. Its validity was tested in terms of content validity, structural validity, convergent validity and criterion validity.Results:The system′s Cronbach′s α was determined to be 0.86. Its one-dimension composite reliability was 0.939, its split-half reliability coefficient was 0.88 and its parallel-forms reliability was 0.922. The inter-evaluator reliability was between 0.965 and 0.998 [95%CI= (0.919, 0.999)], and the single evaluator ICC value was 0.973 to 0.998 [95%CI= (0.937, 0.999)]. The validity test produced a content validity index of 1, and the Pearson correlation coefficients between each sub-item and the total score were all greater than 0.60. The KMO value for structural validity was 0.882, and there was a common factor in the component matrix which reflected 60.9% of the information in the original variables. The system′s convergent validity AVE was 0.609 with Pearson correlation coefficients between the multidimensional system and the FMA-UE and ARAT both > 0.70.Conclusion:The multi-dimensional quantitative video evaluation system has good reliability and validity in the evaluation of stroke survivors with hand dysfunction.

Objective:To evaluate the reliability and validity of the Chinese version of HEMO-FISS-QoL(HF-QoL) questionnaire (HF-QoL-C) in the Chinese population with hemorrhoids.Methods:From November 2021 to November 2022, a self-constructed general information questionnaire, HF-QoL-C, and the 36-item short form health survey (SF-36), Goligher classification, and Giordano severity of hemorrhoid symptom questionnaire (GSQ) were used to conduct a questionnaire survey on 760 hemorrhoid patients in the anorectal department of six hospitals. The data was analyzed for reliability and validity using SPSS 21.0 and AMOS 26.0 software.Results:The Cronbach's α coefficient of HF-QoL-C and its dimension ranged from 0.831 to 0.960, and the split coefficient was 0.832-0.915. Four common factors were extracted through principal component exploratory factor analysis. Confirmatory factor analysis indicated acceptable structural validity( χ2/ df=8.152, RSMEA=0.097, CFI=0.881, IFI=0.881, NFI=0.867). HF-QoL-C was correlated with SF36 and GSQ( r=-0.694, 0.501, both P<0.01). There were differences in the total score and dimensional scores of HF-QoL-C between surgical and drug treated patients, different grades of Goligher classification for hemorrhoidal disease, and different ranges of hemorrhoid prolapse (all P<0.001). No ceiling effect was found in the total score and the scores of each dimension(0.3%-2.0%). There was a floor effect in both psychological function and sexual activity dimensions (16.7%, 35.1%). Conclusion:HF-QoL-C has good reliability and validity, which can be used to measure the quality of life of Chinese hemorrhoid patients.
