Alyn水中适应性测试量表2的汉化及在脊髓损伤患者中的信度与效度

Water Orientation Test of Alyn 2(Chinese) and Its Reliability and Validity in Patients with Spinal Cord Injury

目的翻译Alyn水中适应性测试量表2 (WOTA2),并检验其用于脊髓损伤患者的信度和效度。方法获得授权后,将英文版WOTA2及其培训手册翻译成中文。2018年1月至9月,采用汉化后的WOTA2对137例脊髓损伤患者进行评定。先由两名评定者独立进行WOTA2测试;3 d后,其中一名评定者再次进行测试。计算Cronbachα系数、Spearman-Brown系数、组内相关系数(ICC)和Kappa系数评估信度。利用单项内容效度指数(I-CVI)和量表内容效度指数(S-CVI)评价内容效度,利用因子分析评价结构效度。结果中文版WOTA2全部条目Cronbachα系数为0.947,心理适应条目为0.890,水中技能条目为0.954。奇偶折半法两部分评分之间Pearson相关系数为0.948,折半信度为0.973。重测ICC总分为0.965,百分制总分为0.965,心理适应部分为0.847,水中技能部分为0.970;评定者间ICC总分为0.964,百分制总分为0.965,心理适应部分为0.847,水中技能部分为0.970。27个条目重测Kappa系数为0.528～0.927,评定者间为0.478～0.936。I-CVI为0.8～1.0,S-CVI为0.63。因子分析提取4个公共因子,符合理论预设,累积方差贡献率67%。结论中文版WOTA2应用于脊髓损伤患者有良好的信度和效度,可在国内水中运动疗法临床实践中推广应用。

Objective To translate theWater Orientation Test of Alyn 2(WOTA2)into Chinese,and to study its reliability and validity for patients with spinal cord injury.Methods After authorizing,the English version WOTA2 scale and its training package were translated into Chinese.From January to September,2018,137 patients with spinal cord injury were evaluated with the Chinese version WOTA2 by two evaluators independently,and evaluated again three days later by one of the evaluators.The Cronbach'sα,Spearman-Brown coefficient,intra-group correlation coefficient(ICC)and Kappa coefficient were calculated to evaluate the reliability.Content Validity Index(CVI)of items(I-CVI)and scale(S-CVI)were used to evaluate the content validity,and factors analysis was used to evaluate the structure validity.Results The Cronbach'sαwas 0.947 in all items of the scale,0.890 in mental adjustment items and 0.954 in aquatic skills items.Pearson correlation coefficient of the half scales separated by odd and even items was 0.948,and the Spearman-Brown coefficient was 0.973.The ICC of test-retest was 0.965 in total score,0.965 in centesimal system total score,0.847 in mental adjustment score and 0.970 in aquatic skills score.The ICC of inter-testers was 0.964 in total score,0.965 in centesimal system total score,0.847 in mental adjustment score and 0.970 in aquatic skills score.The Kappa coefficient was 0.528 to 0.927 in test-retest and 0.528 to 0.927 in inter-testers.The I-CVI was 0.8 to 1.0 and S-CVI was 0.63.Factors analysis extracted four factors,which met the theory,and contributed 67%of cumulative variance.Conclusion The Chinese version WOTA2 is good in reliability and validity for patients with spinal cord injury,and can be used in the clinical practice of aquatic therapeutic exercise in China.
