Background: Stressful life events (SLEs), impulsivity, aggression, and hostility are known risk factors for suicide. The existence of an “I-A-H Triad” (composed of impulsiveness, aggressiveness and hostility) is proposed as a mediating factor between SLEs and suicide. Method: Data on 399 deceased people (274 from suicide, 125 from other causes) were collected through psychological autopsy. The Paul Ramsey Life Experience Scale (to collect SLE history), the Barrat Impulsivity Scale (BIS-11) and the Buss-Durkee Hostility Inventory(BDHI) were applied, using versions adapted for psychological autopsy. Results: Comparative analysis of the two groups showed significant differences in the variables of interest (SLE: t = 7.280; BDHI: t = 4.201; BIS-11: t = 3.812; I-A-H Triad: t = 4.84). Mediation analysis confirmed the role of the I-A-H Triad in mediation of the presence of SLEs and the type of death. Conclusions: High levels of impulsivity, aggression, and hostility increase the risk of suicide when a person is faced with SLEs.

Antecedentes: Los acontecimientos vitales estresantes (AVE), la impulsividad, agresividad y hostilidad son conocidos factores de riesgo para el suicidio. Se propone la existencia de una “Tríada I-A-H” (compuesta por impulsividad, agresividad y hostilidad) como factor mediador entre los AVE y la muerte por suicidio. Método: datos de 399 personas fallecidas (274 por suicidio, 125 por otras causas) fueron recogidos mediante autopsia psicológica. Se aplicaron versiones adaptadas para autopsia psicológica de las escalas Paul Ramsey Life Experience Scale para recoger historia de AVE, la Escala de impulsividad de Barrat (BIS-11) y la Buss-Durkee Hostility Inventory (BDHI). Resultados: Los análisis de comparación entre los dos grupos mostraron diferencias significativas en las variables de interés (AVE: t = 7,280; BDHI: t = 4,201; BIS-11: t = 3,812; Triada I-A-H: t = 4,84). Los análisis de mediación confirmaron el papel mediador de la “tríada I-A-H” entre la presencia de AVE y el tipo de fallecimiento. Conclusiones: Elevados niveles de impulsividad, agresividad y hostilidad aumentan el riesgo de suicidio ante AVE.
