History of trauma and COVID-19-related psychological distress and PTSD
Bibliographic record
Abstract
The COVID-19 pandemic has a great impact on society as a whole. Yet the pandemic and associated mandatory lockdown in several countries may have increased the vulnerability of certain populations. The present study aimed to document the frequency of clinical level of psychological distress and COVID-19 related post-traumatic stress symptoms in youth during the first wave of the pandemic. The study more specifically explored the role of prior trauma and adverse life events as a vulnerability factor for negative outcomes. A sample of 4914 adolescents and young adults from the province of Quebec, Canada was recruited online through social networks during the first wave of COVID-19. Results revealed that 26.6% of youth displayed serious psychological distress and 20.3% probable PTSD symptoms. The number of past traumas and adversity experienced showed a dose-response relation with the prevalence of psychological distress and PTSD. After controlling for socio-demographic characteristics and COVID-19 related variables (exposure, fear, suspicion of having the infection), participants with a history of five traumas and more presented a two-fold risk of serious psychological distress and probable PTSD. Emotion dysregulation was also associated with an increased risk of symptoms while resilience was linked to a reduced risk of distress.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
