RESUMO
BACKGROUND: Adverse childhood experiences (ACEs) represent a key risk factor for suicidal thoughts and behaviors among adolescents. However, the intervening mechanisms linking ACEs and suicidality, and whether such processes vary by gender, remain underexplored. OBJECTIVE: The present study examines whether the relationships between ACEs and the likelihood of experiencing suicidal thoughts and attempting suicide are indirect through depressive symptoms and low self-control. This study also investigates whether these direct and indirect paths might be moderated by gender. PARTICIPANTS AND SETTING: The analyses make use of data on a statewide representative sample of students enrolled in public high schools in Florida (N = 23,078) from the 2022 Florida Youth Substance Abuse Survey (FYSAS). METHODS: Generalized structural equation modeling (GSEM) was used to estimate the direct and indirect effects of ACEs on the likelihood of suicidal thoughts and attempting suicide. The indirect effects were assessed using bootstrapping, and between-gender differences in the coefficients were tested. RESULTS: ACEs has direct associations with depressive symptoms, low self-control, and both suicidality outcomes. The effects of ACEs on suicidal thoughts are indirect through both depressive symptoms and low self-control, and the effects of ACEs on suicide attempts are indirect through depressive symptoms. Limited gender differences in these pathways emerge. CONCLUSIONS: For male and female youth, ACEs are associated with heightened depression symptoms and reduced self-control, and both of these factors partially explain the previously established relationship between ACEs and suicidality.
