Uncensored traumatic video exposure linked to higher PTSD severity in post-October 7 cohort

Background. Digital media increasingly shape how populations encounter large-scale traumatic events, enabling real-time exposure to uncensored graphic content among individuals who are not directly exposed. However, whether this form of indirect exposure to the trauma relates to posttraumatic stress responses, particularly in the wake of collective, large-scale trauma, remains poorly understood. Methods. We studied a large cohort of individuals in the first months following a collective trauma, in which a significant portion reported symptoms of post-traumatic stress disorder (PTSD) related to the October 7th events in 2023 although none were directly exposed. Participants were assessed for mental health symptoms, demographic background, social and psychological factors, and degree of trauma exposure concerning geographic, i.e., physical proximity from threat, interpersonal, e, g., death of close family/friend, and media, i.e., censored and uncensored watching and reading trauma content. Results. Around 24% of the sample met clinical threshold for PTSD. Intrusive and hyperarousal symptom clusters were commonly endorsed. Hierarchical regression analysis revealed that greater exposure to uncensored traumatic video content through affected social networks was associated with higher PTSD symptom severity, above and beyond other important risk factors including mental health history, reduced perceived resilience and social support, and degree of religiosity, and other forms of trauma exposure. Conclusions. The findings identify exposure to uncensored traumatic digital content as a distinct dimension of indirect trauma exposure and suggest that features of contemporary media environments may shape early post-traumatic responses during collective crises.
