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 stress significantly predicted decreased mental health at Time 2, and self-control acted as a mediator in such relationship. The results of the behavioral and brain model analyses found that zfALFF in the right temporal region negatively predicted self-control. Functional connectivity between the right temporal region and the right precentral gyrus was also found to negatively predict self-control.

Conclusion

This study highlights the mediating role of self-control in the relationship between perceived stress and mental health. It also identifies specific brain regions and functional connectivity associated with self-control, providing new neurobiological evidence for mental health interventions.

期刊介绍： The International Journal of Clinical and Health Psychology is dedicated to publishing manuscripts with a strong emphasis on both basic and applied research, encompassing experimental, clinical, and theoretical contributions that advance the fields of Clinical and Health Psychology. With a focus on four core domains—clinical psychology and psychotherapy, psychopathology, health psychology, and clinical neurosciences—the IJCHP seeks to provide a comprehensive platform for scholarly discourse and innovation. The journal accepts Original Articles (empirical studies) and Review Articles. Manuscripts submitted to IJCHP should be original and not previously published or under consideration elsewhere. All signing authors must unanimously agree on the submitted version of the manuscript. By submitting their work, authors agree to transfer their copyrights to the Journal for the duration of the editorial process.
