Chineseization Of The Salt- And Oil-restricted Dietary Behavior Assessment Scale For Hypertensive Patients And Its Application In A Middle-aged And Young Adult Population

ObjectiveTo translate the Measuring Change in Restriction of Salt(Sodium)in Diet in Hypertensives(MCRSDH),the Measuring Change in Dietary-oil Diet Behavior Change Questionnaire(MCDCQ),and Brislin’s cross-cultural translation method was used to translate and develop the Chinese Version of the Measuring Change in Restriction of Salt(Sodium)in Diet in Hypertensives,the Measuring Change in Dietary-oil Diet Behavior Change Questionnaire.The MCRSDH and MCDCQ were tested for reliability and validity to explore the applicability of the two scales among young and middle-aged hypertensive patients in China.Methods1.After obtaining authorization from the authors of the original scales,we Chineseized the MCRSDH and MCDCQ based on Brislin’s principles of cross-cultural translation.The specific steps included translation of the scales,comparison and synthesis,back translation,finding differences,expert review and cultural debugging.After a small sample pre-survey,review by the original authors and various experts,the final draft of the Chinese version of the MCRSDH and MCDCQ scales was formed.2.Using a continuous enrollment method,the population with essential hypertension attending the outpatient department of cardiology in a tertiary hospital in Hefei was selected successively from December 2021 to July 2022 as the study population,and the general information questionnaire and the Chinese version of the MCRSDH and MCDCQ scales were distributed.After collecting and organizing the data,the reliability and validity of the two scales were tested separately,using internal consistency reliability and retest reliability to assess the reliability of the scales,and content validity and structural validity to test the validity of the scales.Results1.In this study,the evaluation criteria introduced by the scales were strictly followed during the cross-cultural adjustment process,and the two scales finally formed the first draft of the Chinese version of the MCRSDH and MCDCQ scales,which mainly included participatory talk(5 entries each for strengths and weaknesses),behavioral assertiveness(5 entries),physical environment change(3 entries),emotional change(3 entries),behavior change practices(3 entries),social environment change(3entries),for a total of 6 dimensions and 29 entries.2.The content validity of the Chinese version of MCRSDH was 0.96,and the content validity of each entry was 0.83～1.There were 29 entries in the scale,and the exploratory factor analysis extracted 5 common factors in the initial stage with a cumulative variance contribution of 70.663%,and 4 common factors in the continuous stage with a cumulative variance contribution of 85.274%.The validated factor analysis showed that the 9-factor model fitted well.The Cronbach’s alpha coefficient for the total scale was 0.822,and the Cronbach’s alpha coefficients for each dimension of the two models ranged from 0.812 to 0.938,with a retest reliability of 0.769-0.951.3.The Chinese version of the MCDCQ has a content validity of 0.96 and the content validity of each item is 0.83 to 1.The scale has a total of 29 entries and the exploratory factor analysis showed that the cumulative variance interpretation rate of the five common factors extracted by MCDCQ initiation(MCDCQ-INIT)was 85.96%,the cumulative variance interpretation rate of the four factors extracted by MCDCQ sustenance(MCDCQ-SUST)was 86.92%.The Confirmatory factor analysis(CFA)confirmed the validity of both model constructs,indicating good construct validity of the scales.The Cronbach’s α coefficient of the scale was 0.859,and the Cronbach’s αcoefficients for each dimension of the two models ranged from 0.784 to 0.940,with a retest reliability of 0.767 to 0.934.ConclusionsThe Chinese versions of MCRSDH and MCDCQ have good reliability and validity,and can be used as tools to assess behavioral changes in salt consumption diet and behavioral changes in cooking oil diet in young and middle-aged patients with essential hypertension in China.
