中文版骨质疏松认知量表的信效度

Reliability and validity for Chinese version of the osteoporosis prevention and awareness tool

目的对骨质疏松认知量表(osteoporosis prevention and awareness tool,OPAAT)进行翻译,并对翻译后的中文版进行信效度分析。方法随机抽取长沙市中南大学湘雅二医院580例住院患者,采用中文版骨质疏松认知量表进行测量。结果回收有效问卷562份,回收率为96.90%,修订后的中文版骨质疏松认知量表(Chinese version of osteoporosis prevention and awareness tool,OPAAT-C)共22条目,条目与量表总得分的相关系数为0.393~0.650(P<0.001)。OPAAT-C的内部一致性Cronbach'sα系数为0.862,重测信度为0.858(P<0.001)。同时效度:OPAAT-C与骨质疏松知识评估工具(osteoporosis knowledge assessment tool,OKAT)总得分间的相关系数为0.719(P<0.001)。探索性因子分析共提取4个公因子,累积方差贡献率为46.303%。验证性因子分析:适配度指数(goodness-of-fit index,GFI)为0.938,调整后适配度指数(adjusted goodness-of-fit index,AGFI)为0.923,比较适配度指数(comparative fit index,CFI)为0.929,基准化适配度指数(normed fit index,NFI)为0.868,残差均方和平方根(root mean square residual,RMR)为0.010。结论中文版骨质疏松认知量表信效度考评指标均达良好,符合心理计量学标准,可用于评估公众对骨质疏松症的认知水平。

Objective To translate the English version of the osteoporosis prevention and awareness tool(OPAAT)into Chinese,and the reliability and validity of the Chinese version was tested.Methods A total of 580 inpatients were recruited randomly from a hospital in Changsha and were investigated using the Chinese version of OPAAT.ResultsThere were 562 participants who completed and returned valid questionnaires(valid return rate was 96.90%).The Chinese version of OPAAT(OPAAT-C)was revised from 30 items to 22 items,and the correlations between the items and total scale ranged from 0.393 to 0.650(P<0.001).The internal consistency Cronbach's coefficient of the Chinese-edition OPAAT(OPAAT-C)was 0.862,and the correlation of test-retest reliability was 0.858 for whole instrument.The concurrent validity was 0.719(P<0.001).Four factors were extracted by exploratory factors analysis and it could explain 46.303%of the total variance.The confirmatory factor analysis revealed a good model fit.The goodness-of-fit index(GFI),adjusted goodness-of-fit index(AGFI),comparative fit index(CFI),normal fit index(NFI),and root mean square residual(RMR)were 0.938,0.923,0.929,0.868,and 0.010,respectively.Conclusions The Chinese version of OPAAT(OPAAT-C)is proved to be reliable and eligible.It can be used to assess the public's cognitive level of osteoporosis.
