BIRTH-RELATED PSYCHOLOGICAL TRAUMA PERCEPTION SCALE DEVELOPMENT AND PSYCHOMETRIC PROPERTIES: A METHODOLOGICAL STUDY

Purpose: The purpose of this study was to develop a valid and reliable measurement tool for assessing mothers' psychological trauma perception regarding birth. Materials and methods: This is a methodologically type study. This study was conducted with 430 mother who had normal delivery. Personel information form and Birth-related psychological trauma perception scale draft form were used to data curation. Results: The statistics show that the sample is sufficient for factor analysis (Kaiser-Meyer Olkin measure = 0.858) and that the correlation between the questions is appropriate (Bartlett's test of sphericity, chi 2 = 9211.281, p = 0.001). The total explained variance of the scale is 28.309%. It was determined that the scale consists of 39 items and a single sub-dimension. The internal consistency coefficient of the total scale was calculated as 0.92. The scale's invariance over time shows that its reliability is high (r = 0.83, p< 0.001). Conclusion: Results showed that the developed scale is a valid and reliable tool for measuring the perception of traumatic birth. This scale can be used to determine whether women are susceptible to psychological trauma from the first postpartum month to a year later.
