B - 78 Examining how Adverse Childhood Experiences and the Underlying Processes of Trait and State Impulsivity Influence Suicidal Behavior.

This article focuses on the relationships between Adverse Childhood Experiences (ACEs), impulsivity traits and states, and suicidal behavior. Using data from 311 adults recruited via Amazon Mechanical Turk, the study assessed ACEs, suicidal behaviors, and multiple dimensions of impulsivity, including negative urgency, lack of premeditation, and sensation seeking. Findings indicate that higher ACE scores predict impairments in response inhibition and increased impulsivity, with specific impulsivity traits and poor time perception significantly associated with greater suicidal behavior. The results suggest that individuals with more ACEs who act rashly under negative emotions and show less regard for consequences are more likely to progress from suicidal ideation to planning and attempts. Identifying these risk factors may help target interventions for those at elevated risk of suicidal behavior.
