Suicidal risk and impulsivity-related traits among young Argentinean college students during a quarantine of up to 103-day duration: Longitudinal evidence from the COVID-19 pandemic

Aim
This study aimed to examine longitudinal changes on suicidal risk levels, adjusting for impulsivity-related traits, quarantine duration, main demographic factors, mental disorder history, and loneliness, in young Argentinean college students with (ideation; attempt) and without suicidal behavior history, during a quarantine of up to 103-day duration of the COVID-19 pandemic.
Methods
A longitudinal design with two-repeated measures was used (N = 1202). Follow-up was a month later from the first measurement. Three groups were analyzed: with suicidal ideation history, with suicide attempt history, and without suicidal behavior history.
Results
Percentages of college students with high or moderate suicidal risk were alarming (accumulated: 62.23% first measurement, 57.65% second measurement). Multilevel analysis on the three groups showed that suicidal risk diminished from the first measurement to the follow-up, having mental disorder history predicted higher suicidal risk, and negative urgency had the largest increasing effects on suicidal risk which persisted over time.
Conclusions
Suicidal risk widely affects college students during lengthy quarantines of the COVID-19 pandemic and it should be tracked in those having pre-existing vulnerabilities, but also in those without. Education on managing negative emotions may help decrease suicide risk in college students during the COVID-19 pandemic.
