![]() In populations with risk factors such as operative birth or giving birth to a child with very low birth weight, even up to 15.7 or 18.5% of women might be affected ( 3, 4). Recent data suggest, that giving birth even without any further medical complications for mother or child may lead to PTSD in 3–4% of women and the prevalence might increase during the first year postpartum ( 1– 4). In addition, this work provides a basis to assess childbirth-related PTSD in studies conducted with a longitudinal study design or in high-risk samples. Besides an improvement in clinical routine it will help to make data on prevalence of childbirth-related PTSD internationally comparable. Limitations: Data were acquired in a community sample and prevalence rates might not be representative for mothers of high-risk groups, e.g., after preterm birth.Ĭonclusions: The German version of the City BiTS is the first German questionnaire which allows to assess symptoms of childbirth-related PTSD according to DSM-5 criteria. Correlation analyses showed convergent validity of the City BiTS (total scale and subscales) with the IES-R and PCL-5 and divergent validity with the EPDS and the DASS-Anxiety. In a confirmatory factor analysis (CFA) in the holdout sample the two-factorial solution reached the best model fit out of three models. Internal consistency was good to excellent for the subscales and the total scale (Cronbach's Alpha = 0.89−0.92). The factors “Childbirth-related symptoms” and “General symptoms” explained about 53%, 52% of variance. ![]() Results: Exploratory factor analysis (EFA) on a random split-half sample confirmed the previously reported two-factorial structure of the City BiTS. Methods: A community sample of 1,072 mothers completed an online survey, which included questions on sociodemographic and obstetric characteristics, the German version of the City BiTS, the Impact of Event Scale-Revised (IES-R), the PTSD Checklist for DSM-5 (PCL-5), Edinburgh Postnatal Depression Scale (EPDS), and the anxiety subscale of the Depression, Anxiety, and Stress Scale (DASS-Anxiety). Since no questionnaire on childbirth-related PTSD is available in German, we aimed to validate a German translation of the City BiTS and to provide information on its psychometric properties. Surprisingly, the recently developed City Birth Trauma Scale (City BiTS) was the first diagnostic tool for childbirth-related PTSD covering DSM-5 criteria for PTSD. 7Faculty of Medicine, Institute and Policlinic of Occupational and Social Medicine, Technische Universität Dresden, Dresden, Germanyīackground: About 3–4% of women in community samples suffer from childbirth-related posttraumatic stress disorder (PTSD).6Department of Child Health and Development, Norwegian Institute of Public Health, Oslo, Norway.5Institute for Systems Medicine (ISM), Faculty of Human Medicine, Medical School Hamburg, Hamburg, Germany. ![]() 4Department of Clinical Neuroscience, Osher Center for Integrative Medicine, Karolinska Institutet, Stockholm, Sweden. ![]()
