Assessment of posttraumatic stress disorder among women after childbirth using the City Birth Trauma Scale in Spain Caparrós González, Rafael Arcángel Romero González, Borja Peralta Ramírez, María Isabel Ayers, Susan Galán Paredes, Alejandro Caracuel Romero, Alfonso PTSD Postpartum Questionnaire Validation Spanish Postpartum post-traumatic stress disorder (PP-PTSD) affects 3.1-6.3% of women after childbirth. The City Birth Trauma Scale (City-BiTS) is a questionnaire designed to evaluate and diagnose this disorder, according to the DSM-5 criteria, including the following groups of symptoms characteristic of post-traumatic stress: re-experiencing, avoidance, negative cognitions and mood, and hyperarousal. The aim of the present study was to evaluate the psychometric properties of the Spanish-language version of this questionnaire (City-BiTS-S), based on a community sample of Spanish women. A total of 207 mothers, recruited at three health centres in southern Spain, completed the City-BiTS-S questionnaire and provided sociodemographic and obstetric data. Exploratory factor analysis (EFA) of the data replicated the two-factor structure reported in previous studies that explained 47.9% of the variance: Factor 1 of general symptoms, and Factor 2 of birth-related symptoms. Both City-BiTS-S (Cronbach’s α = 0.90) and the two factors (Cronbach’s α for Factor 1 = 0.89; Cronbach’s α for Factor 2 = 0.82) presented high internal consistency. Rasch analysis confirmed the unidimensionality of the two factors as valid subscales of the PP-PTSD. It also confirmed that the item about ‘Not being able to remember details of the birth’ should be reviewed. Rasch analysis also suggested the item ‘Flashbacks to the birth and/or reliving the experience’ should be reworded in the Spanish version. In conclusion, the City-BiTS-S presents appropriate psychometric properties to measure symptoms of postpartum_PTSD. Nevertheless, further research is recommended to confirm its validity in a clinical population and in different medical approaches to the birth process. 2021-10-20T10:53:29Z 2021-10-20T10:53:29Z 2021 info:eu-repo/semantics/article Published version: Caparros-Gonzalez, R.
