Validity and reliability of the Turkish version of the City Birth Trauma Scale (CityBiTS).

The City Birth Trauma Scale (CityBiTS) was developed to be consistent with the current Diagnostic and Statistical Manual of Mental Disorders-DSM-5. It has been used as a complementary instrument that measures the psychological trauma related to childbirth. The aim of this study was to investigate the validity and reliability of the Turkish version of the CityBiTS. This research is a methodological study. This study was conducted with 315 women who had 6-month-old infants from August to October 2018. The CityBiTS is a 29-item instrument that was developed according to DSM-5 criteria to assess childbirth-related Post-Traumatic Stress Disorder. Test-retest measurements were performed at two-week intervals to evaluate the invariance of the scale over time. Cronbach's alpha coefficient of reliability was used to analyse internal consistency of scale. Cronbach's alpha coefficients were .76 for re-experiencing symptoms, .57 for avoidance symptoms, .77 for negative cognitions and mood, .83 for hyperarousal and .82 for dissociative symptoms. In conclusion, The Turkish version of the CityBiTS, as an instrument developed to be consistent with DSM-5 criteria in assessing childbirth-related trauma symptoms, is a valid and reliable tool.Impact statementWhat is already known on this subject? One of the possible barriers for this is the lack of validated questionnaires that measure the postpartum PTSD.What do the results of this study add? The aim of this study was to investigate the validity and reliability of the Turkish version of the CityBiTS. The City Birth Trauma Scale has good psychometric properties and the two symptom clusters identified are consistent with previous research on symptoms of postpartum PTSD.What are the implications of these findings for clinical practice and/or further research? The City Birth Trauma Scale provides with a measure of birth-related PTSD foruse in research and clinical practice.

The prevalence of posttraumatic stress disorder in pregnancy and after birth: A systematic review and meta-analysis.

BACKGROUND: Previous reviews have provided preliminary insights into risk factors and possible prevalence of Post-traumatic Stress Disorder (PTSD) postpartum with no attempt to examine prenatal PTSD. This study aimed to assess the prevalence of PTSD during pregnancy and after birth, and the course of PTSD over this time. METHODS: PsychINFO, PubMed, Scopus and Web of Science were searched using PTSD terms crossed with perinatal terms. Studies were included if they reported the prevalence of PTSD during pregnancy or after birth using a diagnostic measure. RESULTS: 59 studies (N =24267) met inclusion criteria: 35 studies of prenatal PTSD and 28 studies of postpartum PTSD (where 4 studies provided prevalence of PTSD in pregnancy and postpartum). In community samples the mean prevalence of prenatal PTSD was 3.3% (95%, CI 2.44-4.54). The majority of postpartum studies measured PTSD in relation to childbirth with a mean prevalence of 4.0% (95%, CI 2.77-5.71) in community samples. Women in high-risk groups were at more risk of PTSD with a mean prevalence of 18.95% (95%, CI 10.62-31.43) in pregnancy and 18.5% (95%, CI 10.6-30.38) after birth. Using clinical interviews was associated with lower prevalence rates in pregnancy and higher prevalence rates postpartum. LIMITATIONS: Limitations include use of stringent diagnostic criteria, wide variability of PTSD rates, and inadequacy of studies on prenatal PTSD measured in three trimesters. CONCLUSIONS: PTSD is prevalent during pregnancy and after birth and may increase postpartum if not identified and treated. Assessment and treatment in maternity services is recommended.

The effects of antenatal education on fear of childbirth, maternal self-efficacy and post-traumatic stress disorder (PTSD) symptoms following childbirth: an experimental study.

BACKGROUND: Fear of birth and low childbirth self-efficacy is predictive of post-traumatic stress disorder symptoms following childbirth. The efficacy of antenatal education classes on fear of birth and childbirth self-efficacy has been supported; however, the effectiveness of antenatal classes on post-traumatic stress disorder symptoms after childbirth has received relatively little research attention. PURPOSE: This study examined the effects of antenatal education on fear of childbirth, maternal self-efficacy and post-traumatic stress disorder symptoms following childbirth. DESIGN: Quasi-experimental study. METHODS: The study was conducted in a city located in the Middle Anatolia region of Turkey and data were collected between December 2013 and May 2015. Two groups of women were compared-an antenatal education intervention group (n=44), and a routine prenatal care control group (n=46). The Wijma Delivery Expectancy/Experience Questionnaire, Version A and B, Childbirth Self-efficacy Inventory and Impact of Event Scale-Revised was used to assess fear of childbirth, maternal self-efficacy and PTSD symptoms following childbirth. RESULTS: Compared to the control group, women who attended antenatal education had greater childbirth self-efficacy, greater perceived support and control in birth, and less fear of birth and post-traumatic stress disorder symptoms following childbirth (all comparisons, p<0.05). CONCLUSIONS: Antenatal education appears to alleviate post-traumatic stress disorder symptoms after childbirth.
