Study On The Localization,reliability And Validity Of Family Resilience Assessment In Breast Cancer Patients

ObjectiveThis study aimed to introduce and localize the Family Resilience Assessment（FRA）,complete cross-cultural adjustment,and form the Chinese Version of Family Resilience Assessment（C-FRA）.The reliability and validity of the C-FRA were tested to explore its applicability in Chinese breast cancer patients.Methods（1）Localization of the FRA:Based on the Brislin translation model,after obtaining Dr.Duncan’s authorization,the Chinese version of Family Resilience Assessment I was formed according to translation,back-translation and inspection.（2）Expert Consultation:19 experts from Anhui,Jiangsu,and Zhejiang provinces were consulted by the Delphi method to conduct cross-cultural adjustment of the scale.The C-FRAⅡwas revised and improved according to the final results of expert consultation.（3）Preliminary survey:By convenience sampling method,30 breast cancer patients was selected from the oncology department of a tertiary hospital in Anhui Province to fill in the C-FRA II,which was revised and improved to form the C-FRA test version.（4）Reliability and validity test:Convenience sampling method was used to select 334breast cancer patients from a tertiary hospital in Anhui Province to fill in the general information questionnaire,the C-FRA test version and the Resilience Scale to evaluate the reliability and validity of the C-FRA.The reliability included Cronbach’s alpha coefficient,split-half reliability coefficient,and retest reliability.The validity included content validity,construct validity,and calibration validity.The item analysis,the coefficient of variation,the critical ratio and the correlation coefficient methods were used to analyze the items.Results（1）In the two rounds of Delphi expert consultation,the experts’positive degree was100%,the authority degree（Cr）was 0.908,the familiarity degree（Cs）was 0.895,the judgment basis（Ca）was 0.921,and the coordination degree of opinion（Kendall’s W）was0.230 and 0.169（P<0.001）.In terms of the concentration degree of expert opinions,the mean importance scores of items were 3.800～4.867 and 4.263～4.947,and the coefficient of variation was 0.052～0.267 and 0.046～0.219 respectively.The C-FRAⅡcontained 29 items in nine dimensions:making meaning of adversity,positive outlook,transcendence and spirituality,flexibility,connectedness,social and economic resources,communication processes clarity,open emotional sharing and collaborative problem solving.（2）The final C-FRA had a total of 28 items.Exploratory factor analysis extracted 5common factors:positive attitude,family connection,social and economic resources,clear communication,cooperative problem solving,and cumulative variance,with a cumulative variance contribution rate of 70.862%.Confirmatory factor analysis results showed that:X~2/df=2.375,RMSEA=0.079,CFI=0.916,TLI=0.902,GFI=0.800,and NFI=0.864.The Cronbach’s alpha coefficient of the scale was 0.961,and the test-retest reliability was 0.884.The scale of CVI was 0.967,the items CVI was 0.867～1.000,and the criterion-related validity was 0.607（P<0.01）.ConclusionThe Chinese Version of Family Resilience Assessment was proved to be a good instrument with acceptable reliability and validity,and it is qualified to assess family resilience among Chinese breast cancer patients.
