Psychological resilience mediates the association of the middle frontal gyrus functional connectivity with sleep quality

Abstract

The ability to recover from stress, which is essential for sleep quality, is characterized as psychological resilience. Meanwhile, poor sleep quality is commonly related to low psychological resilience. However, the neurological underpinnings of psychological resilience, as well as the neural substrates of the links between psychological resilience and sleep quality in healthy brains, remain not well understood. Based on the recent studies that the middle frontal gyrus (MFG) acted a important role in psychological resilience. The current study sought to determine the association between functional connectivity of the MFG and psychological resilience in 144 young college students using resting-state functional connectivity (rs-FC) analysis. Then, we examined how psychological resilience-related functional connectivity was linked to sleep quality. Results indicated that the MFG functional connectivity was observed to associate with psychological resilience. These connectivities involved the right middle cingulum gyrus (rMCG), the right precentral gyrus (rPreCG), the left postcentral gyrus (lPoCG), and the left thalamus. In addition, mediation analysis suggested that psychological resilience played a mediating role in the relationship among the rMFG-rMCG, the rMFG-rPreCG, the rMFG-lPoCG, and the lMFG-left thalamus and sleep quality. Overall, the current study offers new evidence for the neurological underpinnings of psychological resilience and brings to light an underlying mechanism that the relationship between MFG connectivity and sleep quality is mediated through psychological resilience.

Individuals with higher trait self-esteem prefer to use reappraisal, but not suppression: Evidence from functional connectivity analyses

“…Moreover, age and gender were regarded as covariates. This approach is also in line with prior neuroimaging studies (Kong et al, 2020;Shi et al, 2022;Zhang et al, 2020). In this model, path a represented the effect of X on M, path b was calculated from regressing Y on M after controlling for X, path c' represented the direct effect of X on Y after controlling M, and path ab was equal to the multiplication of path a and path b, representing the indirect effect of X on Y through M. In addition, path c was equal to the sum of the direct effect and indirect effect, which is also recognized as the total effect.…”

Psychological resilience mediates the association between sleep quality and anxiety symptoms: A repeated measures study in college students

“…The possible reason for this is that psychological resilience contributes to positive emotional recovery [ 16 ]. Further, some other studies have found an association between sleep quality and psychological resilience [ 15 , 31 ]. The possible reason for this is that poor sleep quality leads to poor psychological stress capacity.…”

“…Stress perception refers to the ability to perceive various negative external factors, which often serves as an important factor in predicting the occurrence of depression. The involvement of the MFG in emotional processing is related to psychological resilience ( 42 , 43 ). The MSFG and MFG are important components of the default network and frontal parietal network.…”
