Development and Reliability and Validity Testing of the Intravenous Thrombolysis Intention Scale for Acute Ischemic Stroke
摘要
Abstract
Objective To develop an intravenous thrombolysis intention scale for acute ischemic stroke and evaluate its reliability and validity.Methods This study used the theory of planned behavior as a guiding framework,forming an initial draft of the scale through literature analysis,Delphi expert consultation,and pre-survey.From July to August 2023,a questionnaire survey was conducted at three screening sites for high-risk stroke populations in Zhengzhou,Henan province,and the scale was analyzed for item analysis,reliability testing,and structural validity assessment.From September to October 2023,another survey was conducted to carry out confirmatory factor analysis and criterion-related validity assessment.Results The intravenous thrombolysis intention scale for acute ischemic stroke comprised one overall evaluation item and three dimensions,totaling 13 items.The content validity index at the scale level was 0.9.Exploratory factor analysis extracted three common factors,contributing to a cumulative variance rate of 70.515%after rotation.The Cronbach's α coefficient of the scale was 0.904,the split-half reliability was 0.840,and the test-retest reliability was 0.872.The results of the confirmatory factor analysis indicated that the scale demonstrated robust convergent and discriminant validity.The correlation coefficient between the overall scale score and the chronic disease health literacy scale score was 0.671(P<0.001),and the correlation coefficient with respondents'perceived risk of intracerebral hemorrhage complications after thrombolysis was-0.402(P<0.001).Conclusions The intravenous thrombolysis intention scale for acute ischemic stroke exhibits good reliability and validity,and can be used to assess the intention level of intravenous thrombolysis in cases of acute ischemic stroke.关键词
