Study On Pain Resilience And Associated Factors In Patients With Coronary Heart Disease

Objective:1.To translate the Pain Resilience Scale(PRS)into Chinese and evaluate its psychometric characteristics in patients with coronary heart disease with chest pain.2.To explore the main factors affecting pain resilience in patients with coronary heart disease.Methods:1.After obtaining the authorization of the source table,according to the Brislin translation principle to translate,retranslate and cross-cultural adapt the English version to Chinese version.2.By convenience sampling method,347 patients with coronary heart disease hospitalized in the department of Cardiology of a tertiary hospital in tianjin were investigated formally,and the reliability and validity of the Chinese version of the Pain Resilience Scale were tested.Internal consistency reliability and retest reliability were selected for reliability.Content validity,structure validity and criterion validity were used for validity.Statistical methods included exploratory factor analysis,confirmatory factor analysis and correlation.3.We used questionnaires concerning pain resilience,pain self-efficacy,medical coping modes,perceived Social Support,anxiety,depression,pain catastrophizing.Statistical methods included independent sample t test,one-way anova,correlation,and multiple stepwise regression.Results:1.The content validity and criterion validity were 0.939 and 0.852 respectively.Through EFA,the Chinese version of PRS included three dimension which accounted for 58.214% of the accumulated variance,and each item had high factor loading quantity(>0.5).CFA showed that the modified model fitted well.Cronbach'a was0.821 and the test-retest reliability was 0.911.2.The score of pain resilience of patients with coronary heart disease was 33.78±5.65.3.Univariate analysis showed that there were significant differences in pain resiliencescores among seven variables,including gender,education level,occupation,place of residence,medical payment methods,admission times due to coronary heart disease and duration of pain per visit.Pain self-efficacy,perceived Social Support and active coping were positively correlated with pain resilience,while pain intensity,pain catastrophizing,anxiety,depression and passive coping were negatively correlated with pain resilience.4.Multivariate analysis showed that passive coping,pain catastrophizing,depression,pain self-efficacy,perceived Social Support,anxiety,duration of pain > 10 minutes each time,hospitalization times for coronary heart disease(CHD)> 3 times in the past and pain intensity entered a rergression equation with pain resilience as dependent variable,which accounted for 74.4% of the accumulated variance,standardized partial regression coefficients were respectively-0.252?-0.250?-0.172?0.162?0.151?-0.111?-0.102?-0.090?-0.073.Conclusions1.The Chinese version of pain resilience scale has good reliability and validity.The potential theoretical structure of the Chinese version of PRS is basically consistent with the source scale,but it can subdivide the dimensions.PRS was recommended as an assessment tool to evaluate pain resilience in clinical investigation and research.2.Passive coping,pain catastrophizing,depression,pain self-efficacy,perceived Social Support,anxiety,duration of pain > 10 minutes each time,hospitalization times for coronary heart disease(CHD)> 3 times in the past are the main factors affecting the pain resilience in patients with coronary heart disease.Pain self-efficacy and perceived social support were protective factors,while other variables were risk factors.Therefore,in the future researches,resilience training programs that combine risk factors reduction and protective factors promotion should be designed pertinetly to verify the effectiveness,acceptability and feasibility of this program in patients with coronary heart disease,so as to promote the development of pain resilience and promote cardiac rehabilitation.
