Translation, Revision And Application Of The Mindful Self-care Scale Among ICU Nurses

Objectives:(1)To translate the English version of Mindful Self-care Scale(MSCS)into Chinese,and examine the reliability and validity of Chinese version MSCS;(2)To investigate the status of mindful self-care among ICU nurses,identify it’s influence factors.Methods:(1)The introduction of the Chinese version of MSCS:Using the cross-cultural adaptation guidelines to Chineseize the MSCS developed by Cook-Cottone and other scholars,including forward translation,comprehensive review,back translation,cultural adaptation,and pre-survey to form a Chinese version of MSCS.(2)The reliability and validity test of the Chinese version MSCS:Selecting 540 ICU nurses from three hospitals in Changsha,which were administered the MSCS and Mindful Attention Awareness Scale during August 2021 to November 2021.Use item analysis method to screen and analyze the entry performance of the Chinese version of MSCS;the reliability of the Chinese version of MSCS was presented by Cronbach’sαcoefficient,half reliability,and test-retest reliability.The validity of Chinese version of MSCS was presented by content validity,criterion-related validity,construct validity,convergent validity and discriminant validity.(3)The application of MSCS:Selecting 157 ICU nurses in the ICU of three hospitals in Changsha as the research objects for a cross-sectional survey during December 2021 to January 2022.Using general data,Chinese version of the MSCS and Professional Quality of Life Scale.Comparing the differences in mindful self-care among different indicators in each categorical variable by single factor analysis.Analyzing the correlation coefficients between mindful self-care and professional quality of life by using correlation analysis.Exploring the Influencing factors by multiple linear regression analysis with stepwise procedure.Results:(1)The introduction of the Chinese version of MSCS:By Chineseized the original MSCS,the Chinese version of the MSCS was obtained.The number of dimensions was the same as the original English scale,but one item was deleted from the number of items.There are 6dimensions of mindfulness relaxation,physical care,self-compassion and purpose,supportive relationships,supportive structures and mindfulness awareness,with 32 items.(2)The reliability and validity test of the Chinese version MSCS:The correlation coefficient between each item and the total score of the scale in this study was 0.433～0.658(P<0.05).The correlation coefficient between each dimension and the total score of the scale was 0.617～0.768(P<0.05).The Cronbach’sαcoefficient of the scale was 0.921,and the Cronbach’sαof each dimension was 0.806～0.929.The total split-half reliability coefficient was 0.784,and the split-half reliability coefficient of each dimension was 0.764～0.903.The total test-retest reliability was0.962,and the test-retest reliability of each dimension was 0.838～0.928.Ten experts assessed the scale.The item-level content validity index was above 0.70,and the scale-level content validity index was 0.906.The score of the Chinese version of MSCS was positively correlated with the score of the Mindful Attention Awareness Scale(r=0.688,P<0.001).In the exploratory factor analysis,the KMO value was 0.905,and the Barlett’s sphericity test reached a significant level(χ~2=5023.258,P<0.001).The principal component analysis method and the maximum variance orthogonal rotation method were used to extract a total of 6feature for common factors with roots greater than 1,and the cumulative variance contribution rate was 64.846%.According to confirmatory factor analysis,the model fitted well and adaptation was ideal.The item factor load corresponding to each dimension of the scale was greater than 0.5.The average variance extracted of each dimension was more than 0.4,and the combined validity was more than 0.8.At the same time,The correlation coefficients between dimensions were 0.102～0.204,which were all smaller than the corresponding square root of average variance extracted.(3)The application of MSCS:The total score of mindful self-care about 157 ICU nurses was averagely(93.29±15.47),and the average score of items was(2.92±0.48).The results of univariate analysis showed that in sociodemographic data,there were statistically significant difference in the mindful self-care level of ICU nurses with different gender,age,current number of children,working years,technical titles and whether they had received mindfulness related training(P<0.05).Pearson correlation analysis of continuous variables showed that the level of mindful self-care was significantly correlated with professional quality of life(P<0.05).The results of multiple linear regression analysis showed that gender,age,current number of children,compassion satisfaction and job burnout had an impact on mindful self-care score.The five variables could explain 35.30%of the total variation.Conclusion:(1)The Chinese version of the Chinese version of MSCS in this study is structurally consistent with the original scale,the number of dimensions remains unchanged,and one item is deleted from the number of items,so the Chinese version of the MSCS has a total of 6dimensions and 32 items.It has good reliability and validity,which can be used in ICU nurses;(2)The level of mindful self-care among ICU nurses in domestic is at a low level.The gender,age,current number of children,compassion satisfaction and job burnout are the main influencing factors of the severity of mindful self-care.ICU nurses who are female,younger,have fewer current children,higher levels of compassionate satisfaction,and lower levels of burnout have higher levels of mindful self-care.
