This study aimed to examine how executive functioning (EF) and processing speed (PS) moderate the relationship between adverse childhood experiences (ACE's) and suicidality in cisgender and gender-minority youth (GMY) in an inpatient setting. We hypothesized that neurocognitive domains will moderate the relationship between ACE's and suicidality in GMY. An inpatient psychiatric sample of 43 GMY and 43 cisgender adolescents ages 13-19 (M = 15.02, SD = 1.57) participated in this study. Participants completed the ACEs to measure cumulative trauma exposure, and the Millon Adolescent Clinical Inventory that assessed suicidality. EF and PS composite scores were used as moderators. Two regression models were conducted to examine how EF, PS, ACEs, and the ACEs*EF and ACEs*PS interactions predicted suicidality for cisgender and GMY respectively. For cisgender adolescents, no significance was found in the regression model (F(5,36) = 1.11, p = 0.370) or interactions between ACEs and EF (b = -2.24, p = 0.122) or PS (b = 2.14, p = 0.390). Although the regression model was not significant (F(5,37) = 1.52, p = 0.207) for GMY, there were significant crossover interactions between ACEs and EF (b = -3.50, p = 0.013; 95%CI = -6.20, -0.80), and PS (b = -3.67, p = 0.027; 95%CI = 0.44, 6.90) on suicidality. These results suggest that EF and PS meaningfully attenuate the relationship between ACEs and suicidality for GMY in an inpatient setting whereas this attenuation is not seen in their cisgender counterparts. Such findings can lead to better indicators and interventions for GMY in inpatient settings.
