Trauma Shaping the Psychopathological Correlates of Patients with Long-COVID: A 6-Months Longitudinal Study with Repeated Measures Mixed Models

Abstract

This research aimed at investigating how the experience of trauma can influence the psychological correlates of long-COVID over time in a clinical sample of patients hospitalized because of COVID-19. Through a longitudinal research design, 70 post-acute patients with COVID-19 were followed-up after hospital discharge in 3-time points up to 6 months and completed the Post-traumatic Stress Disorder Checklist for DSM-5 (PCL-5) and the Symptoms Checklist-90-Revised (SCL-90 R). Repeated measures mixed models with random intercept were used to evaluate the effect of trauma (yes/no) over time (T1, T2, T3) on the SCL-90-R scales. Results showed that patients with trauma display significantly worse psychological outcomes in all the SCL-90-R dimensions [all padj < .05 for the principal effects of trauma(y)], especially in symptoms of depression [time 2 vs time 1*trauma(y): b = -3.86, CI = -7.18 – -0.53, padj = .035; time 3 vs time 1*trauma(y): b = -4.77, CI = -8.10 – -1.45, padj = .011], anxiety [time 3 vs time 1*trauma(y): b = -4.54, CI = -7.72 – -1.37, padj = .011], and obsessive-compulsive difficulties [time 3 vs time 1*trauma(y): b = -4.03, CI = -7.20 – -0.86, padj = .027]. These findings shed light on the long-term psychological consequences of COVID-19 among hospitalized patients and highlight the key role of trauma, suggesting its assessment to tailor psychological interventions.
