Transitioning from perceived stress to mental health: The mediating role of self-control in a longitudinal investigation with MRI scans.

ABSTRACT:

Background

The neural mechanisms and long-term effects of perceived stress (PS) and self-control (SC) on mental health (MH) are not fully understood. This study seeks to investigate the influence of PS and SC on MH and to identify their neural correlates using fMRI.

Methods

A total of 817 college students participated in behavioral assessments, including the Perceived Stress Scale (PSS), Self-Control Scale (SCS), and Mental Health Continuum Short Form (MHC-SF). Among them, 371 underwent fMRI scans to calculate zfALFF and whole-brain functional connectivity. Additionally, their behavioral measures were reassessed two years later.

Results

Longitudinal behavioral data revealed significant fixed effects of perceived stress and self-control on mental health. Perceived stre
