Twelve-month suicidal ideation, incidence and persistence among college students pre-pandemic and during the pandemic: A longitudinal study

The present study explored whether there had been significant changes in 12-month suicidal thoughts, incidence, and persistence of suicidal ideation among college students prior to and during the COVID-19 pandemic. Data were drawn from the French portion of the World Mental Health International College student Survey Initiative (WMH-ICS), a prospective cohort survey initiated in 2017. Students who completed both the baseline and one-year follow-up surveys were included (n = 1,216). Lifetime suicidal ideation and behaviors and mental disorders were assessed at baseline, and 12-month suicidal ideation and behaviors were also assessed at one-year follow-up. Logistic regressions were used to determine whether the odds of 12-month suicidal ideation at follow-up was associated with COVID-19 pandemic period while adjusting for lifetime psychopathology. No significant change in the odds of 12-month suicidal ideation was observed during the pandemic when compared to pre-pandemic times. Adjusting for prior psychopathology, 12-month suicidal ideation was not significantly associated with pandemic times, nor was incidence or persistence. No evidence of a significant increase in suicidal thoughts during the pandemic was observed. Longer follow-up periods and larger samples are needed in order to determine whether suicidal ideation and behaviors remain stable in the future.
