Depression is associated with frontal alpha asymmetry (FAA) and Psychological Resilience (PR), although in different ways. Only cursory attention has been given to how these three constructs interact despite the possible clinical and research implications of those associations. One limitation of recent research into these associations has been conceptualising PR as a unitary construct, whereas it has been shown to be multi-component. This study investigated the underlying components of PR, their correlations with FAA, and the effect that participants' depressive status had upon those correlations in a community sample of 54 males and 46 females aged between 18 yr and 75 years. Results confirmed the overall inverse association between total PR and depression for four of the original five PR components and for one of the two components found in this sample. Similarly, there were differences between the ways that FAA and PR components were associated, depending upon the depressive status of participants. Source localisation data indicated that the PR components were not uniformly correlated with alpha activity in the same brain regions. These findings of content, efficacy, and neurophysiological differences between the five components of PR and their associations with FAA argue against consideration of PR as a unitary construct.
抑郁症与额叶α波不对称性(FAA)和心理韧性(PR)相关,尽管方式不同。尽管这些关联可能具有临床和研究意义,但对于这三个概念如何相互作用,人们只是粗略地关注了一下。近期对这些关联的研究存在一个局限性,即把心理韧性概念化为一个单一的结构,而实际上它已被证明是多成分的。本研究在一个由54名男性和46名女性组成的社区样本中进行,这些参与者年龄在18岁至75岁之间,调查了心理韧性的潜在成分、它们与额叶α波不对称性的相关性,以及参与者的抑郁状态对这些相关性的影响。结果证实,对于最初五个心理韧性成分中的四个以及在该样本中发现的两个成分之一,心理韧性总分与抑郁症之间总体呈负相关。同样,根据参与者的抑郁状态,额叶α波不对称性与心理韧性成分之间的关联方式也存在差异。源定位数据表明,心理韧性成分与大脑相同区域的α波活动并非均匀相关。心理韧性五个成分之间在内容、功效和神经生理学方面的差异及其与额叶α波不对称性的关联,这些发现反对将心理韧性视为一个单一的结构。
