Abstrakt: Background: Despite preliminary evidence that links impulsivity to suicide risk among Native American youth, impulsivity has not been directly studied in relation to suicide ideation (SI) or behaviors in this population. We examined indexes of rapid-response impulsivity (RRI) across multiple levels of analysis (self-report, behavioral, neurobiological) and associations with SI among Native American youth ages 9-10 in the Adolescent Brain Cognitive Development Study.
Methods: Data from the sample (n = 284) included self-report (UPPS-P), behavioral (Stop Signal Task), and neurobiological (right inferior frontal gyrus activation) indicators of RRI. RRI indicators were modeled using variable-centered (i.e., traditional multivariable regression) and person-centered (i.e., clustering analyses) approaches in measuring their association with SI.
Results: Logistic regression analysis demonstrated that higher negative urgency was associated with higher odds of SI (Adjusted Odds Ratio (AOR) = 1.23, p = 0.015). Latent profile analysis clustered youth into five profiles based on within-individual variation in RRI indicators. Youth with an elevated self-reported negative and positive urgency profile were at higher odds of reporting SI than "normative" youth (AOR = 2.38, p = 0.019).
Limitations: Limitations of this study include the modest sample size particularly regarding SI (14.1 %), potential bias in estimates of lifetime SI, and generalizability to youth from specific Native American communities.
Conclusions: Negative urgency may increase risk for SI among Native American youth in late childhood. Clinical implications, including the potential for person-centered RRI profiles to act as candidate markers of suicide risk and resilience in adolescence and inform safety assessments and planning, are discussed.
