Maladaptive emotion regulation (ER) strategies are a transdiagnostic construct in psychopathology. ER depends on cognitive control, so brain activity associated with cognitive control, such as frontal theta and beta, may be a factor in ER. This study investigated the association of theta and beta power with positive affect and whether emotion regulation strategies explain this association. One hundred and twenty-one undergraduate students (mean age = 20.74, SD = 5.29; 73% women) completed self-report questionnaires, including the Emotion Regulation Questionnaire and the Positive and Negative Affect Schedule. Spectral analysis was performed on resting state frontal electroencephalogram activity that was collected for eight 1-min periods of alternating open and closed eyes. Relative beta and theta band power were extracted relative to global field power at frontal channels. Regression analysis revealed that positive affect is significantly predicted by theta power (β = 0.24, p = .007) and beta power (β = -0.33, p < .0001). There was an indirect effect of beta power on positive affect via reappraisal, but not suppression. Additionally, theta power significantly predicted suppression, but no indirect effect was observed between theta power and positive affect. These findings are consistent with a prior study reporting a positive and negative relationship between theta and beta power, respectively, and positive affect induction. This study elucidates how modulation of theta and beta bands link to ER strategies.
适应不良的情绪调节（ER）策略是精神病理学中的一种跨诊断结构。情绪调节依赖于认知控制，因此与认知控制相关的大脑活动，如额叶θ波和β波，可能是情绪调节的一个因素。本研究调查了θ波和β波功率与积极情绪之间的关联，以及情绪调节策略是否能解释这种关联。121名本科生（平均年龄=20.74，标准差=5.29；73%为女性）完成了自我报告问卷，包括情绪调节问卷和正负情绪量表。对静息状态下额叶脑电图活动进行了频谱分析，该活动在睁眼和闭眼交替的八个1分钟时间段内收集。相对于额叶通道的全局场功率提取相对β波和θ波频段功率。回归分析显示，积极情绪由θ波功率（β=0.24，p=0.007）和β波功率（β=-0.33，p<0.0001）显著预测。β波功率通过重新评估对积极情绪有间接影响，但通过抑制则没有。此外，θ波功率显著预测抑制，但未观察到θ波功率与积极情绪之间的间接影响。这些发现与之前一项研究一致，该研究分别报告了θ波和β波功率与积极情绪诱导之间的正负关系。本研究阐明了θ波和β波频段的调制如何与情绪调节策略相关联。
