# Neurobehavioral pathways linking socioeconomic status hardship to suicide risk versus resilience in young adolescents: the roles of sleep health and default mode network connectivity

## TL;DR

This study explores how socioeconomic hardship affects suicide risk in adolescents through sleep health and brain network connectivity.

## Contribution

The study identifies sleep health and Default Mode Network coherence as mediators and moderators in the link between socioeconomic hardship and suicide risk.

## Key findings

- Increased socioeconomic hardship is linked to higher suicidal ideation and attempts in adolescents.
- Shorter sleep duration mediates the relationship between socioeconomic hardship and suicidal ideation.
- Higher Default Mode Network coherence reduces the negative impact of socioeconomic hardship on suicidal ideation.

## Abstract

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 suicidal ideation and attempts. Shorter sleep duration mediated the association with ideation, while high DMN coherence attenuated the indirect effect of SES-H on ideation via sleep. Findings highlight sleep health as a mechanism connecting socioeconomic adversity to suicidality and suggest DMN coherence may function as a neuroprotective factor for youth resilience.
