摘　　要：目的对高血压患者限盐饮食行为改变评定量表(measuring change in restriction of salt(sodium)in diet in hypertensives,MCRSDH)进行汉化和信度、效度评价。方法获得原量表开发者授权,对MCRSDH进行汉化并进行跨文化调试。采用方便抽样方法,于2020年11月至2021年1月对长沙市2个主城区4家社区卫生服务中心的700名高血压患者进行调查,评价量表的信度、效度。结果中文版MCRSDH-INIT各条目与总分的相关系数为0.327~0.799,CRSDH-SUST各条目与总分的相关系数为0.468~0.893;各条目内容效度指数为0.802~1.000,总量表内容效度指数为0.914。探索性因子分析表明,MCRSDH-INIT提取的4个公因子累积方差解释率为68.511%,MCRSDH-SUST提取的3个因子累积方差解释率为76.558%,MCRSDH-INIT各条目因子载荷系数为0.541~0.926,MCRSDH-SUST各条目因子载荷系数为0.586~0.888;验证性因子分析显示初始行为改变模型拟合指数:卡方自由度比(χ^(2)/df)=1.732,拟合优度指数(GFI)=0.902,比较拟合指数(CFI)=0.945,近似误差均方根(RMSEA)=0.046,规准适配指数(NFI)=0.931,非规准适配指数(TLI)=0.936;持续行为改变模型拟合指数:χ^(2)/df=1.248,GFI=0.937,CFI=0.971,RMSEA=0.018,NFI=0.943,TLI=0.937。量表Cronbach'sα系数为0.901,重测信度为0.917。结论中文版MCRSDH信度、效度良好,可作为国内高血压患者限盐饮食行为改变评估的测量工具。Objective To develop the Chinese version of measuring change in restriction of salt(sodium)in diet in hypertensives(MCRSDH),and to test its reliability and validity.Methods Authorization was obtained from the original authors of MCRSDH.Cross-cultural revision of the MCRSDH was conducted according to the guidelines from November 2020 to January 2021.Totally 700 patients with hypertension were recruited through convenience sampling from 4 community health service centers in 2 main urban districts of Changsha and investigated by the Chinese version of MCRSDH.Reliability and validity of the scale were assessed.Results The correlation coefficient between each item and the total score ranged from 0.327-0.799 and 0.468-0.893 in MCRSDH initiation(MCRSDH-INIT)and MCRSDH sustenance(MCRSDH-SUST)respectively.The item of content validity index(I-CVI)of each item ranged from 0.802 to 1.000,and the scale of content validity index(S-CVI)was 0.914.Four factors were extracted by exploratory factor analysis(EFA)and could explain 68.511%of the total variance for MCRSDH-INIT.Three factors were extracted by EFA and could explain 76.558%of the total variance for MCRSDH-SUST.Values of factor loading ranged from 0.541 to 0.926 for MCRSDH-INIT,and from 0.586 to 0.888 for MCRSDH-SUST.The Confirmatory factor analysis indicated thatχ^(2)/df=1.732,GFI=0.902,CFI=0.945,RMSEA=0.046,NFI=0.931,TLI=0.936 for initiation model andχ^(2)/df=1.248,GFI=0.937,CFI=0.971,RMSEA=0.018,NFI=0.943,TLI=0.937 for sustenance model.The cronbach'sαcoefficient of the scale was 0.901 and the test-retest reliability was 0.917.Conclusion The Chinese version of the MCRSDH is reliable and valid,and can be used as a tool to MCRSDH in China.
