abstract = {Background: Police and security professionals are routinely exposed to potentially traumatic events as part of occupational duties, placing them at increased risk for post-traumatic stress and broader psychological difficulties. This study aimed to identify latent classes of proximal traumatic exposure among Portuguese police/security professionals and examine their associations with PTSD symptoms and general psychological distress. Methods: A cross-sectional online survey was conducted with Portuguese police/security professionals (N = 644). Latent class analysis (LCA) was applied to 17 indicators of potentially traumatic events coded as directly experienced or witnessed, derived from the Life Events Checklist for DSM-5. PTSD symptoms were assessed using the PTSD Checklist for DSM-5, and general psychological distress was assessed using the Brief Symptom Inventory. Exploratory receiver operating characteristic (ROC) analyses examined whether counts of proximal traumatic events could approximate the LCA-derived classes. Results: A three-class solution was identified, comprising low proximal exposure (37.3%), moderate proximal exposure (40.7%), and high proximal/cumulative exposure (22.0%) classes. The classes reflected a graded cumulative pattern of exposure across traumatic event categories, rather than clearly distinct qualitative configurations defined by specific event types. Higher exposure classes were associated with progressively higher PTSD symptoms and psychological distress, and these associations remained significant after adjustment for sociodemographic and occupational variables. Exploratory receiver operating characteristic (ROC) analyses showed that a simple count of proximal traumatic event categories closely approximated the empirically derived class structure within the present sample. However, the resulting thresholds are sample-specific, exploratory, and should not be interpreted as validated screening cutoffs. Conclusions: Proximal traumatic exposure among police/security professionals appears to follow a graded cumulative structure associated with increased PTSD symptoms and psychological distress. The person-centered analysis provided an empirical test of whether exposure was organized according to qualitatively distinct event configurations or primarily along a cumulative gradient. In this sample, cumulative exposure burden emerged as the dominant organizing dimension. The count-based approximation requires external validation before any screening or decision-making application can be considered. © 2026 by the authors.},

abstract = {Purpose: The present study aimed at investigating which sources of social support best account for pregnant women’s levels of psychological distress and mental well-being during the COVID-19 pandemic. Methods: 274 Italian and Canadian expectant mothers completed an online-based survey including measures of perceived social support (from family, significant other and friends), state anxiety, depressive symptoms, and satisfaction with life. Correlation analyses and amultivariate analysis of covariance were performed to explore how social support from different sources was related to depressive symptoms, state anxiety and satisfaction with life. Results: Different sources of social support contributed to explaining women’s psychological distress and mental well-being. Social support both from family and friends was significantly related to women’s state anxiety and depressive symptoms. Social support from friends was specifically related to women’s satisfaction with life. Conclusion: Our findings endorse the crucial role of perceived social support as a protective factor for pregnant women’s mental health. In the context of the COVID-19 pandemic, our results suggest that support from family seems important in preventing psychological distress, whereas support from friends is also associated with mental well-being. These results may help designing future interventions aimed at improving women’s perinatal mental health in life-threatening conditions. ©, Society for Reproductive and Infant Psychology.},
