Abstract：Objective:To develop a risk assessment scale for maternal pregnancy-related venous thrombosis in China,and to verify its reliability and validity.Methods:The pre-test scale was formed by literature research and two rounds of expert evaluation.It is convenient to select 202 pregnant women for investigation,and carry out item analysis and reliability and validity test of the pre-test scale.Results:The pregnancy-related venous thrombosis risk assessment scale contained 5 dimensions and 16 items,and a total of 6 common factors were extracted by exploratory factor analysis.The cumulative variance contribution rate was 60.832%,the area under ROC curve was 0.836,the Cronbach's α coefficient of the scale was 0.852,and the total retest reliability was 0.920 after two weeks.Conclusion:The pregnancy-related venous thrombosis risk assessment scale developed in this study has good reliability and validity,and can effectively evaluate the risk coefficient of pregnancy-related venous thrombosis in pregnant women.
