Abstract: Objective: To develop and test the Psychometric Properties Evaluation of the Birth Trauma Perception Scale for Women During Vaginal Delivery. Methods: The primary scale was developed by literature review, semi-structured interviews and expert letter consultations. A total of 240 women with vaginal delivery were recruited by convenience sampling from two hospitals in Nanchang city, Jiangxi Province. The final scale was formed after reliability and validity testing. Results: There were 31 items in the scale. A total of 4 factors were extracted by the exploratory factor analysis, and the 4 factors were respectively named as medical support trauma perception, labor pain trauma perception, family support trauma perception, and labor outcome trauma perception. The cumulative variance contribution rate was 69.907%. The average Content Validity Index of the scale was 0.970, and the Item Content Validity Index ranged from 0.860 to 1.000. The Cronbach's α coefficient of the scale was 0.969, and the Cronbach's α coefficient of each dimension ranged from 0.781 to 0.972. The retest reliability coefficient of scale was 0.965 (P<0.05), and the retest reliability coefficient of each dimension ranged from 0.838 to 0.980 (all P<0.05). The half-reliability of the scale was 0.978, and the half-reliability of each dimension ranged from 0.813 to 0.981. Conclusion: The Psychometric Properties Evaluation of the Birth Trauma Perception Scale for Women During Vaginal Delivery has good reliability and validity, and can be used as a measurement tool of birth trauma perception.
