“…Our first finding was that COVID-19-related distress was associated with increased intrusion load, which is in line with previous studies showing that a psychosocial stressor before analogue trauma exposure results in higher intrusion load (Hilberdink et al, 2022 ) and supports the idea that biological stress responses predict subsequent intrusions (Schultebraucks et al, 2019 ). Moreover, our findings align with the assumption that the COVID-19 outbreak had the potential to increase allostatic load (Fofana et al, 2020 ).…”

“…A potential mechanism by which the COVID-19 outbreak may have affected mental health is the modulation of memory processes. Stress has been shown to promote associative learning (Merz et al, 2016 ; Peyrot et al, 2020 ) and analogue intrusions (Hilberdink et al, 2022 ; Schultebraucks et al, 2019 ) by altering neurochemical processes during memory formation. To our knowledge, no study to date has investigated whether the stress brought about by the COVID-19 outbreak might have affected analogue PTSD symptoms and associative learning.…”

Background: The COVID-19 outbreak in early 2020 was associated with an immediate increase in mental health problems in a significant percentage of the general population. Therefore, it is crucial to investigate how the COVID-19 pandemic – as a psychosocial stressor – affected the aetiological processes of mental disorders. Previous research has shown that stress potentiates associative (fear) learning and analogue symptoms of posttraumatic stress disorder (PTSD) and that analogue PTSD symptoms can emerge in response to associative learning. Objective: We investigated whether distress in response to the COVID-19 outbreak support the development of intrusions and rumination after exposure to a non-COVID-19-related analogue trauma. Moreover, we examined if these effects are mediated by the strength of associative learning during analogue trauma. Method: 122 undergraduate university students participated in an online experiment between March and July 2020. They completed questionnaires measuring distress and rumination related to the COVID-19 outbreak. On a subsequent day, they went through an associative learning task, in which neutral stimuli were paired with the appearance of a highly aversive film clip. Subjective ratings were assessed as indicators of associative learning. On the next day, participants documented film-related intrusions and rumination. Results: COVID-19-related distress but not rumination was associated with post-film intrusion and rumination load. These effects were mediated by associative learning. Conclusions: The current findings are in line with the assumptions that stress enhanced both associative learning and PTSD symptoms. Specifically, they indicate that prolonged psychosocial stress – like during the COVID-19 outbreak – is linked to individual differences in memory processing of aversive events. Further confirmatory research is needed to replicate these results.

“…Nevertheless, the actual research shows a contrary situation. The film paradigm seems to trigger a more robust stress response, which may be more similar to real-life trauma (Hilberdink et al, 2022 ). Moreover, the types of trauma (body, sex, traffic, disgust) caused by the themes of different films have different direct subjective and physiological responses (Arnaudova and Hagenaars, 2017 ).…”
