Research On The Chinese Version Of Multidimensional Rumination In Illness Scale

ObjectiveThe purpose of this study was to introduce the Multidimensional Rumination in Illness Scale(MRIS)from abroad,and to localize it in Chinese.A Chinese version of the Multidimensional Rumination in Illness Scale has been established to verify the reliability and validity of the MRIS.MethodsIn the first part,after being authorized by Heather Soo,the author of the MRIS Source Scale translated,retranslated,culturally corrected,and evaluated by experts to form the first version of the scale.30 inpatients were selected for the preliminary experiment,and the Chinese culture of the scale was revised according to the feedback of the patients,thus forming the Chinese version of the MRIS.The second part was to evaluates the reliability and validity of the Chinese version of the MRIS.Referring to the 10th revised edition of the International Classification of Diseases and combining with the opinions of clinical nursing experts,8 kinds of diseases were included:respiratory diseases;digestive diseases;circulatory diseases;endocrine diseases;reproductive and urinary diseases;musculoskeletal diseases;immune and blood diseases;and cancer.The data of 263 inpatients in 14 wards of a third-class hospital in Dalian were collected by convenience sampling method.30patients(more than 3 patients with each disease)were selected by convenience sampling method and re-tested one week later.Excel 2010 was used to establish the database and SPSS22.0 was used to analyze the data,including descriptive statistical analysis,project analysis,Cronbach's?coefficient,split-half reliability,retest reliability and calibration correlation analysis.Amos 21.0 was used for confirmatory factor analysis.Results1.The Chinese version of the MRIS scale has 3 dimensions,including instrumantality,intrusion,brooding.It has good reliability and validity.All the indicators meet the acceptable range of psychological measurement.It is suitable for the evaluation of ruminant thinking of patients with physical illness in China.2.Item analysis:The CR value of each item in the Chinese version of the disease multidimensional ruminant thinking scale ranged from 2.326~14.645(P<0.05).Spearman correlation was used to calculate the correlation coefficient between each item and the total scale score.The correlation coefficient between each item and the total scale was between 0.149 and 0.722(P<0.05).3.Reliability:Cronbach's?coefficient,split-half reliability and retest reliability were used to evaluate the reliability of the Chinese version of the disease multidimensional ruminant thinking scale.Cronbach's alpha coefficient of the total table was 0.949,and the Cronbach's alpha coefficient of constructive rumination,intrusive thinking and forced meditation were 0.80,0.904 and 0.901,respectively;the semi-reliability of the total table was 0.923,and the semi-reliability of constructive rumination,intrusive thinking and forced meditation were 0.716,0.885 and 0.879,respectively;the retest reliability of the total table was 0.792,and constructive rumination thinking was 0.879.The retest reliability of intrusive thinking and forced meditation were 0.675,0.759 and 0.767,respectively.4.Validity:Content validity,calibration correlation and confirmatory factor analysis were used to evaluate the scale validity.Six experts were invited to evaluate the content validity of the disease multidimensional ruminant thinking scale.The scale I-CVI value ranged from 0.83~1.0,and the S-CVI/Ave value was 0.979.Using the RRS as the criterion to evaluate the calibrated correlation degree of MRIS,the total score of the MRIS was positively correlated with the total score of the RRS,and the correlation coefficient=0.192(P<0.05).The scores of intrusion and brooding were positively correlated with the total score of RRS and the scores of each dimension.The correlation coefficient was between 0.150~0.221.The score of instrumentality was not correlated with all dimensions of RRS.Confirmative factor analysis showed that the model fitness index?~2/df=2.355,RMSEA=0.076 and AGFI=0.680 met the fitness standard.ConclusionThe Chinese version of the MRIS scale has 41 items and 3 dimensions.It has good reliability and validity.All the indicators meet the acceptable range of psychological measurement.It is suitable for the evaluation of ruminant thinking of patients with physical illness in China.
