摘要

背景：感知应激（PS）和自我控制（SC）对心理健康（MH）的神经机制和长期影响尚不完全清楚。本研究旨在探讨PS和SC对MH的影响，并利用功能磁共振成像识别它们的神经相关性。方法：对817名大学生进行行为评估，包括压力感知量表（PSS）、自我控制量表（SCS）和心理健康连续量表（MHC-SF）。其中371人接受了fMRI扫描，以计算zfALFF和全脑功能连通性。此外，他们的行为测量在两年后被重新评估。结果：纵向行为数据显示压力感知和自我控制对心理健康有显著的固定影响。感知压力显著预测时间2心理健康下降，自我控制在这种关系中起中介作用。行为和大脑模型分析的结果发现，右颞区zfALFF负向预测自我控制。右颞区和右中央前回之间的功能连接也被发现对自我控制有负面预测。结论：本研究强调了自我控制在感知压力与心理健康之间的中介作用。它还确定了与自我控制相关的特定大脑区域和功能连接，为心理健康干预提供了新的神经生物学证据。

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

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.
