There is a paucity of research characterizing suicide-related factors in victims of early trauma (ET). This cross-sectional study investigated an increase in trait impulsivity of ET victims with suicidal ideation or behavior and its role in severity of psychopathologies and experienced stress. Using data of 401 Korean suicidal ideators and attempters, trait impulsivity, severity of psychopathologies, and stress levels in addition to sociodemographic and clinical characteristics were compared between the ET group and the no ET group. Three first-order factors of trait impulsivity measured in Barratt Impulsive Scale-11 (cognitive instability, motor, and [lack of] perseverance) as well as depression, anxiety, overall stress level, and stress from social relationships were significantly elevated in the ET group. Owing to the long-lasting neurobiological influences of ET, it is recommended clinically that victims be carefully monitored for the development of mental distress, such as depression and anxiety, even in adulthood.
