Pandemic-related PTSD and associated risk factors in the general adult population in the Netherlands

Abstract Introduction The COVID-19 pandemic introduced widespread stressors and shocking events, impacting mental well-being. Understanding posttraumatic stress disorder (PTSD) prevalence during the pandemic is crucial, yet existing studies on this topic vary widely in methodological quality. This study aims to fill this gap using a large-scale national survey study to examine PTSD prevalence during the pandemic and compare pandemic-related and traditional shocking events. Methods This study uses data from the Dutch Public Health Monitor Adults and Elderly 2022, consisting of 365,000 Dutch adults representative for the general adult population. Pandemic-related and traditional events were assessed and anchored to a screening instrument for PTSD: the Dutch version of the PCL-5. Results Two-thirds of participants reported experiencing a shocking event during the pandemic. Exposure to pandemic-related events was reported more frequently than traditional events. Overall probable PTSD prevalence due to these events was 2.4%, evenly split between pandemic-related and traditional events. Among exposed individuals, probable PTSD prevalence was 3.7%. This was higher for traditional than for pandemic-related events. Risk factors for developing probable PTSD after exposure to an event during the pandemic were younger age, financial difficulties, loneliness, low resilience and experiencing multiple events. Discussion Exposure to shocking events during the pandemic influenced the prevalence of probable PTSD. Despite the lower relative impact of pandemic-related shocking events compared to traditional events, exposure to pandemic-related shocking events accounted for the same amount of probable PTSD cases in the Dutch general population as 5 common traditional events. This emphasizes the need to address mental health consequences of prolonged crises and the demand for healthcare, and the importance of mitigation strategies based on risk and protective factors. Key messages • Exposure to pandemic-related events accounted for approximately the same amount of probable PTSD cases as 5 frequently occurring traditional events. • Despite pandemic-related events being reported more frequently, traditional events were associated with a relatively higher prevalence of PTSD.
