Background: The role of insight dimensions – illness recognition (IR), symptoms relabelling (SR), treatment compliance (TC) - in suicide risk in first-episode psychosis (FEP) remains unclear. Methods: The AESOP (n=181) and GAP (n=112) FEP cohorts were followed-up over 10- and 5 years. Survival analysis modelled time to first suicidal event in relation to baseline insight levels (Schedule for Assessment of Insight), whilst adjusting for demographic, clinical, psychopathological and neuropsychological variables. Results: AESOP: those with previous suicide attempts scored higher on IR (7.6±1.9 vs. 5.9±3.0, p<0.01) and total insight (TI) (17.2±5.0 vs. 13.4±6.7, p=0.03). IR (r=0.23, p<0.01), SR (r=0.18, p=0.04) and TC (r=02.6, p<0.01) correlated with depression. Univariable analyses: IR (HR=1.14, 95%CI 0.98-1.34, p=0.09), TC (HR=1.30, 95%CI 0.99-1.71, p=0.06) and TI (HR=1.06, 95%CI 0.99-1.13, p=0.08) were linked with suicidal behaviour. Multivariable regression models: depression (HR=1.55, 95%CI 1.22-1.97, p<0.01) predicted suicidal behaviour. GAP: SR (6.4±3.1 vs. 4.5±3.4, p=0.03) and TI (16.8±6.4 vs. 12.8±7.4, p=0.03) were higher in those with suicidal antecedents. IR (r=0.32, p<0.01) and SR (r=0.27, p=0.01) correlated with depression. Univariable analyses: TC (HR=1.36, 95%CI 1.01-1.83, p=0.04) and TI (HR=1.06, 95%CI 0.99-1.14, p=0.08) were associated with suicidal behaviour. Multivariable regression models: previous suicide attempts (HR 5.17, 95%CI 1.32-20.29, p=0.02) and depression (HR 1.16, 95%CI 1.00-1.35, p=0.04) predicted suicidal behaviour. Conclusions: Suicide attempts prior to FEP and depression at that point, both of which were associated with baseline insight levels and risk of suicidal behaviour over the follow-up, appear to explain the apparent relationship between insight and suicidality in FEP.
