Through a longitudinal survey, data were collected in the general Irish population over 18 years of age (n=1032), who carried out a self-report in May 2020 and a follow-up in August 2020 (n=715). Lifetime prevalence rates were 29.5% for suicidal ideation, 12.9% for non-suicidal self-harm (NSSI), and 11.2% for attempted suicide. There was no change in the rates of NSSI and suicide attempts from the last two weeks during the pandemic. Correlations between indicators of suicidality supported a progression from ideation to NSSI and suicide attempt. Suicidal ideation alone was associated with being male, unemployed, greater loneliness, and less religiosity. NSSI (no concurrent suicide attempt) was associated with a history of mental health treatment. Suicide attempt was associated with ethnic minority status, lower education, lower income, post-traumatic stress disorder, depression, and a history of mental health treatment
