The Chinese Localization Of The Cardiac Rehabilitation Inventory And The Preliminary Application In Rehabilitation Information Support Of Cardiovascular Patients

Objectives1.To translate the English version of the cardiac rehabilitation inventory(CRI)into Chinese and to evaluate the validity and reliability of the Chinese version of CRI in cardiovascular diseases patients.2.To explore the current status of personalized cardiac rehabilitation information needs of patients with cardiovascular diseases and related influencing factors.Methods1.The translation and reliability and validity test of the inventory: We translated the CRI following the Brislin's model from translation to back-translation.220 cardiovascular diseases patients in a hospital and 320 cardiovascular diseases patients in three hospitals were recruited by the general information questionnaire and the Chinese version of the cardiac rehabilitation inventory and analyzed the reliability and validity of the inventory.The data was analyzed by SPSS21.0 and AMOS21.0 software.Pearson correlation analysis ofitem-total score was used to test homogeneity of the Chinese version inventory.Critical ratio was used to analyze the discrimination between items.The inventory validity was tested by structural validity(exploratory factor analysis and confirmatory factor analysis)and content validity.Cronbach's alpha coefficient,half-fold reliability and retest reliability were used to test the reliability of the scale.2.The investigation of the current status: This study is a descriptive study using a convenient sampling method.200 patients with cardiovascular diseases were studied in cardiac rehabilitation wards and cardiac rehabilitation clinics of three tertiary first-class hospitals in Zhengzhou in September to December 2018.The survey was conducted to explore the current status of personalized cardiac rehabilitation information needs of patients with cardiovascular diseases and related influencing factors by using the general information questionnaire,the Chinese version of the cardiac rehabilitation inventory,the self-rated abilities for health practices scale and the social support scale.The data was analyzed by SPSS21.0.Normal data were described by mean±standard deviation,qualitative data were described by frequency and percentage.The difference of data were analyzed by t test or one-way ANOVA,and regression analysis was accomplished by multiple linear regression.Results1.The correlation coefficients between each item score and the total score ranged from 0.304~0.682(P<0.01).Except for item 15 and item 17,the rest are greater than 0.40.The critical ratio of each item showed statistically significant differences(P<0.01).The Scale-Content Validity Index(S-CVI)was 0.96,the Item-Content Validity Index(I-CVI)ranged from 0.83 to 1.00.Exploratory factor analysis extracted three factors,which could explain 56.415% of the total variance.Confirmatory factor analysis(CVI)indicated the indicators of structural equation model fitted well and the standardized regression coefficients ranged from 0.464 to0.880 except for item 9,fitting index ?2/df=2.464,RMSEA=0.068,GFI=0.906,CFI=0.929,IFI=0.929.The Cronbach's ? for the total scale was 0.816,the Cronbach's? for three dimensions ranged from 0.765~0.862,the test-retest reliability coefficient was 0.838.2.Each dimension score of the cardiac rehabilitation inventory in cardiovascular diseases patients: autonomy: 16.95±2.06,process anxiety: 13.42 ±4.18,outcome anxiety: 8.28 ± 2.77.The total score of health behavior self-efficacy is 60.64 ±22.81,including nutrition: 15.35 ± 6.22,psychological well-being: 15.26 ± 6.47,exercise: 14.37±6.64,health responsibility: 15.66±6.21.The total score of social support is 40.78±7.46,including subjective support: 24.72±4.43,objective support:9.38 ± 3.05,utilization of support: 6.68 ± 1.78.Self-efficacy,social support,rehabilitation change stage,and occupational type together account for 33.8% of the regression equation for the patient's autonomy of cardiac rehabilitation.Self-efficacy,social support,rehabilitation change stage,degree of education,and exercise experience together account for 38.7% of the regression equation for the patient's process anxiety of cardiac rehabilitation.Self-efficacy,social support,rehabilitation change stage,current residence,and rehabilitation guidance during hospitalization together account for 32.2% of the regression equation for the patient's outcome anxiety of cardiac rehabilitation.Conclusions1.The Chinese version of CRI has good reliability and validity and can be used to measure the personalized cardiac rehabilitation information needs of patients with cardiovascular diseases.2.Patients with cardiovascular diseases have highest demand for information related to cardiac rehabilitation results.Self-efficacy,social support and rehabilitation change stage all have effects on patients' rehabilitation autonomy,outcome anxiety and process anxiety.Occupation type is an important factor affecting the rehabilitation of patients with autonomy.Degree of education and exercise experience together affect the rehabilitation of patients with process anxiety.Current residenceand rehabilitation guidance during hospitalization together affect the rehabilitation of patients with outcome anxiety.
