Socioeconomic hardship (SES-H) is a known risk factor for adolescent suicidal thoughts and behaviors (STB). This study examined sleep health as a pathway linking SES-H to suicide risk and evaluated the moderating role of Default Mode Network (DMN) coherence. Data came from three waves of the Adolescent Brain Cognitive Development (ABCD) Study (N = 11,878). Increased SES-H predicted greater...

The present study examined default mode network (DMN) neural connectivity patterns among adolescents. Next, we tested two critical markers of sleep health—duration and efficiency, in predicting neural connectivity patterns. Last, we investigated the latent DMN profiles’ predictive utility of internalizing and externalizing symptoms in youth.
Objectives: Youth raised in stressful environments are at increased risk for developing impulsive traits, which are a robust precursor of problem behaviors. Sleep may mediate the link between stress and problem behaviors as it is both sensitive to stress and essential for neurocognitive development underlying behavioral control during adolescence. The default mode network (DMN) is a brain...
