Abstract

Depression is one of the most common mental disorders. Perceived stress is a significant trigger and has adverse effects on depression. The complex longitudinal relationship between perceived stress and depression at the symptom level has significant implications for clinical intervention but is understudied. In our study, 823 students (67% female, median age 20.38, IQR 19.42-21.43) from a university in Tianjin were randomly sampled and completed measures of PHQ-9 and PSS-10, while 393 (65% female, median age 20.42, IQR 19.46-21.45) were followed up at three points, six months apart. The longitudinal relationships were estimated using cross-lagged modelling and cross-lagged panel network modelling. Among them, 49 students (59% female, median age 19.48, IQR 18.76-20.12) participated in resting-state functional magnetic resonance imaging (fMRI) scans. Cross-lagged analyses showed that depression and perceived stress predicted each other at the global level. At the dimensional level, depression and perceived helplessness were mutually predictive, while depression and perceived coping did not. In the cross-lagged panel network analyses, we identified symptoms in the top 20% of Bridge Expected Influence as bridging symptoms, specifically 'Guilt' (PHQ6) and 'Felt nervous and stressed' (PSS3). Notably, 'guilt' consistently demonstrated the highest Bridge Expected Influence across all time points and showed the strongest predictive power for perceived stress. We found that fALFF in the left superior frontal gyrus (SFG) mediated the association between "guilt" and perceived stress. Our findings elucidate the bidirectional relationship between symptoms of depression and perceived stress, identifying guilt is the most critical symptom of depression for the followed perceived stress, with SFG activity mediating this association.

中国大学生抑郁症状与压力感知的纵向关系
抑郁症是最常见的精神障碍之一。感知到的压力是一个重要的触发因素,对抑郁症有不利影响。在症状水平上,感知压力和抑郁之间复杂的纵向关系对临床干预具有重要意义,但尚未得到充分研究。本研究随机抽取天津某高校823名学生(67%,中位年龄20.38岁,IQR 19.42 ~ 21.43)完成PHQ-9和PSS-10测试,393名学生(65%,中位年龄20.42岁,IQR 19.46 ~ 21.45)在间隔6个月的3个点进行随访。纵向关系估计使用交叉滞后模型和交叉滞后面板网络模型。其中49名学生(女性59%,中位年龄19.48岁,IQR 18.76 ~ 20.12)接受静息态功能磁共振成像(fMRI)扫描。交叉滞后分析表明,抑郁和感知压力在全球水平上是相互预测的。在维度水平上,抑郁与感知无助相互预测,而抑郁与感知应对不相互预测。在交叉滞后面板网络分析中,我们将桥梁预期影响的前20%的症状确定为桥接症状,特别是“内疚”(PHQ6)和“感到紧张和压力”(PSS3)。值得注意的是,在所有时间点上,“内疚”始终显示出最高的桥梁预期影响,并显示出对感知压力最强的预测能力。我们发现,左额上回(SFG)的fALFF介导了“内疚”和感知压力之间的关联。我们的研究结果阐明了抑郁症状与感知压力之间的双向关系,在随后的感知压力中,识别内疚是抑郁最关键的症状,而SFG活动介导了这种关联。

期刊介绍: Stress is a normal component of life and a number of mechanisms exist to cope with its effects. The stresses that challenge man"s existence in our modern society may result in failure of these coping mechanisms, with resultant stress-induced illness. The aim of the journal therefore is to provide a forum for discussion of all aspects of stress which affect the individual in both health and disease. The Journal explores the subject from as many aspects as possible, so that when stress becomes a consideration, health information can be presented as to the best ways by which to minimise its effects.
