Abstract:
Objective To develop a Psychological Birth Trauma Assessment Scale and to test its reliability and validity.Methods Through literature review,semi-structured interview,expert conference,Delphi expert enquiry and preliminary investigation,a pre-test scale was formed.From March to May 2023,postpartum women from 38 hospitals of different levels in 15 provinces(Jiangsu,Anhui,Zhejiang,Fujian,Tibet,and Shanghai,etc.)were conveniently selected for investigation.The sample size of the first-round survey was 547,which was used for reliability and validity test.The sample size of the second-round survey was 550,which was used for confirmatory factor analysis.Results The psychological birth trauma assessment scale consisted of 2 parts,with a total of 29 items in 6 dimensions.The intrapartum feeling part included 4 dimensions,with a cumulative variance contribution rate of 63.992％,and the postpartum effect part included 2 dimensions,with a cumulative variance contribution rate of 68.208％.The content validity index of the scale was 0.947,and the content validity index of each item was 0.809～1.000.The total score of the scale and the scores of each dimension were significantly negatively correlated with the total score of the calibration scale(r=-0.784～-0.533,P＜0.001).The total Cronbach's α coefficient was 0.941,and the split-half reliability coefficient was 0.883.Confirmatory factor analysis showed that the main evaluation indicators were all within the acceptable range.Conclusion The Psychological Birth Trauma Assessment Scale has good reliability and validity,and it can be used as an assessment tool for the degree of maternal psychological birth trauma.
