Overview

Baseline neural assessment may refine stress evaluation; leaves open causal effects on outcomes and requires prospective validation.

Key Points

  • To investigate the nonlinear relationship between perceived chronic stress and resting-state neural indices of approach motivation.
  • Measured perceived chronic stress levels alongside baseline resting-state electroencephalography (EEG) recordings.
  • Analyzed resting-state neural activation associated with approach motivation across low, moderate, and high chronic stress profiles.
  • Demonstrated a statistically significant nonlinear, U-shaped relationship between chronic stress and approach motivation (p < 0.05).
  • Observed heightened resting-state activation of approach motivation at both low and high chronic stress levels, alongside reduced activation at moderate stress levels.

Main Result

p-value: p=< 0.05

The study demonstrates a U-shaped relationship between chronic stress and resting-state approach motivation, highlighting the importance of assessing baseline neural states in stress adaptation.

Cite This Study

Xi et al. (2026) conducted an observational in Perceived chronic stress. Perceived chronic stress was evaluated on Resting-state activation of approach motivation (p=< 0.05). Perceived chronic stress demonstrated a U-shaped, nonlinear relationship with resting-state activation of approach motivation (P<0.05).
