Development Of Anxiety Screening Scale For Patients With Cardiovascular Disease And Its Reliability And Validity

Objective:To develop an anxiety screening scale for patients with cardiovascular disease,and explore the factor structure,the reliability and validity tests on the scale.Methods:Establish a pool of scale items based on literature,diagnostic criteria for anxiety disorders,existing anxiety assessment scales,and patient interviews,and screen the scale items after expert consultation,and patient pre-investigation,forming 32 items Pre-test version of the Cardiac Anxiety Scale.Sampling of 100 inpatients and 100 outpatients in the Department of Cardiology and 100 outpatients in the First Clinical Medical College of Shanxi Medical University,completed the preliminary version of the Cardiac Anxiety Scale and Generalized Anxiety Scale,and randomly selected 30 patients after 2 weeks Re-evaluate.Perform item analysis,validity and reliability tests on the scale to form the official version of the Cardiac Anxiety Scale.Results:The official version of the Cardiac Anxiety Scale finally contains 14 items and 3dimensions,which are worry and insomnia,nervousness and panic,and physical symptoms.Validity test: the 3-factor model explained 58.814% of the total variation cumulatively.The correlation coefficients between the factors and the total score were0.869,0.855,and 0.756,respectively,and the correlation coefficients between the factors were between 0.421 and 0.639.The total score of the scale The correlation coefficient with GAD-7 is 0.721,and the correlation coefficient between factors and GAD-7 total score is 0.705,0.627,0.432,respectively.Reliability test: The Cronbach α coefficient of the official version of the scale is 0.870,the Cronbach α coefficient of each dimension of the scale is 0.798,0.802 and 0.717,and the total score of the scale has a test-retest reliability of 0.906,and the test-retest reliability of each dimension is respectively 0.876,0.701,and 0.922.Conclusion:The Cardiac Anxiety Scale developed in this study has good reliability and validity,and can accurately and reliably reflect the anxiety status of patients with cardiovascular disease.
