We included papers who used psychological autopsy methodology, assessed adult death by suicide, and included assessment of impulsivity. We excluded papers about assisted suicide, terrorist suicide, or other cause of death other than suicide or postmortem diagnosis made only from medical records or database. 97 articles were identified. 33 were included in the systematic review and nine in the meta-analysis. We found that people who die by suicide with high impulsivity are associated with younger age, substance abuse, and low intention to die, whereas those with low impulsivity were associated with older age, depression, schizophrenia, high intention to die and low social support. In the meta-analysis, suicide cases had higher impulsivity scores than living controls (Hedges' g = 0.59, 95 % CI [0.28, 0.89], p=.002). However, studies showed heterogeneity (Q = 90.86, p<.001, I2=89.0 %). Impulsivity-aggressiveness interaction was assessed through meta-regression (β=0.447, p=.045). Individuals with high impulsivity would be exposed to a higher risk of fatal suicide behaviour, aggressiveness would play a mediating role. People who die by suicide with high and low impulsivity display distinct characteristics, which may reflect different endophenotypes leading to suicide by different pathways. info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 3.9 2024 PSYCHIATRY 55 / 288 = 0.191 2024 Q1 T1 PSYCHIATRY 55 / 288 = 0.191 2024 Q1 T1 1.606 2024 Psychiatry and Mental Health 2024 Q1 Biological Psychiatry 2024 Q1 8.6 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Vera-Varela, Constanza Alacreu-Crespo, Adrián Universidad de Zaragoza (orcid)0000-0002-0633-2810 Perea-González, María Isabel Guija, Julio Antonio Giner, Lucas 4009 680 Universidad de Zaragoza Dpto.
