COVID-19 posttraumatic stress disorder and mental health among spanish adolescents: SESSAMO project

Background: child and adolescent mental health problems have increased after the COVID-19 pandemic. The objective of this study was to establish the association of the presence and intensity of posttraumatic stress due to COVID-19 with the presence of (1) self-harm and suicide risk, (2) depressive and anxious symptoms, (3) eating disorders and (4) problematic Internet and video game use. Methods: a cross-sectional analysis was performed on a sample of second-fourth grade secondary school students (14 to 16 years old) from Navarra and the Canary Islands recruited at the SESSAMO project. Validated questionnaires were used to assess the intensity of posttraumatic stress due to COVID-19, risk of suicide and presence of self-harm, symptoms of mental disorder and problematic use of the Internet and video games. Results: out of 1423 participants analyzed, those with the highest level of posttraumatic stress showed a significant increase in the risk of suicide (OR = 5.18; 95% CI = 2.96-9.05) and in the presence of eating disorder symptoms (OR = 3.93; 95% CI = 2.21-7.00), and higher anxiety and depression scores (b coefficient for anxiety = 11.1; CI = 9.7-12.5; for depression = 13.0; CI = 11.5-14.5) as compared to those with the lowest level. Participants with a high level of posttraumatic stress were almost 10 times more likely to present problematic video game use (OR = 9.49; 95% CI = 3.13-28.82). Conclusions: years after the pandemic, posttraumatic stress derived from it continues to impact the mental health of adolescents. Further long-term research is needed, as well as close follow-up and intervention in this population.
