Post-traumatic stress disorder symptoms related to work in pediatric departments aremajor public health problems, as they directly affect health organizations, healthcare workers, and, due to the poor quality of care, the patients as well. The post-traumatic symptoms that a healthcare worker may experience are related to intrusion, avoidance, negative changes in cognition and mood, and changes in arousal and reactivity. The aim of the present investigation was to identify risk factors that contribute to the development of PTSD in pediatric healthcare workers, in order to implement necessary workplace measures. A sample of four hundred and forty-five pediatric workers at seven Greek public hospitals consented to participate in the survey. Socio-demographic data and a post-traumatic checklist (5th edition) were used to diagnose post-traumatic stress disorder. According to the results, risk factors for the development of post-traumatic symptoms include medical or nursing errors, threats to a child’s life, and incidents of workplace bullying. More specifically, 25.2% of the participants had a provisional PTSD diagnosis, 72.8%of the sample experienced an incident involving a medical or nursing error in their workplace related to the treatment or care of a child, 56% experienced an incident involving a child’s death or a threat to a child’s life due to a serious illness or injury, and 55.5% experienced an incident of workplace bullying. In addition, it was found that having a university-level education, master’s, or PhD, working in a circular shift, being assigned to a department by management rather than the worker, and dissatisfaction with salary were associated with post-traumatic stress disorder. The high rates of PTSD symptoms among participants highlight the need for prevention and management measures to protect and support the mental health of workers in pediatric departments. We propose frequent evaluations of the mental health of employees, more time for rest, incentives for professional development, utilization of their specializations and specialties, support from mental health specialists when symptoms are diagnosed, and the option for employees to change departments if they wish or if they show symptoms of mental trauma.

Background/Objectives: Childbirth, although generally a positive life event, can sometimes be experienced as traumatic, leading to postpartum post-traumatic stress disorder. Emergency caesarean section and operative vaginal delivery are associated with elevated psychological distress, while factors such as lifetime trauma, domestic violence, anxiety, and coping strategies may further increase vulnerability. Methods: This prospective cohort study included 113 postpartum women who delivered via emergency caesarean section (73.5%) or operative vaginal delivery (26.5%) in two tertiary hospitals in Athens, Greece (March–July 2023). Data were collected at three time points: the second postpartum day, six weeks postpartum, and three months postpartum. Descriptive statistics were used to summarize sample characteristics. Chi-square tests were performed for categorical variables and independent sample t-tests for continuous variables. Multivariate logistic regression analyses were conducted to identify predictors of postpartum post-traumatic stress disorder, with results expressed as odds ratios (OR) and 95% confidence intervals (CI). Results: At six weeks postpartum, 14.2% of participants met full diagnostic criteria for P-PTSD. Postpartum post-traumatic stress was strongly associated with higher state and trait anxiety, fewer positive coping strategies, and exposure to domestic violence (lifetime, during pregnancy, and in the past year). Women with traumatic childbirth experiences had a 14.7-fold higher risk of developing P-PTSD. Lifetime trauma, particularly physical or sexual abuse and exposure to disasters, further increased vulnerability. Over the last three months, 50% of those initially diagnosed continued to meet the diagnostic criteria. Multivariate analysis identified traumatic childbirth, state anxiety, and domestic violence during pregnancy as significant predictors of postpartum post-traumatic stress. Conclusions: Postpartum post-traumatic stress is a significant and underestimated consequence of high-risk deliveries. Screening for domestic violence and trauma history during pregnancy, assessing perinatal anxiety, and providing trauma-informed psychological support are critical to reducing maternal psychiatric morbidity and promoting maternal-infant well-being.

Purpose The present study aims to psychometrically evaluate the Greek version of the Brief IPF scale (B-IPF), with emphasis on its validity, reliability and predictive ability for post-traumatic stress disorder (PTSD) in paediatric healthcare professionals. Methods The sample consisted of 445 paediatric healthcare professionals working in pediatric settings. Exploratory and confirmatory factor analysis methods, Cronbach’s alpha, HAM-A and PCL-5 correlations, ROC analysis and logistic regression were used. Results A univariate scale structure was confirmed with high internal consistency (α = 0.874). A significant association with anxiety and PTSD was observed, and the optimal cut-off score (17) showed an AUC = 0.841. The B-IPF demonstrated high sensitivity (78.6%) and specificity (79%) in predicting PTSD. Discussion The Greek version of the B-IPF has proven to be a reliable and valid screening tool, suitable for application in high occupational risk environments. The study contributes to the cross-cultural documentation of the tool and highlights the importance of early detection of trauma in health professionals. The present study investigates the psychometric validity and reliability of the Greek version of the Brief IPF (B-IPF) scale in paediatric healthcare professionals in order to assess its ability to predict the presence ofthe effects of the traumatic experience in workplace. The results support the use of the B-IPF as a reliable and valid screening tool in high-risk environments.
