情感波动（即变异性）通常被概念化为心理和行为健康状况不佳的标志。目前的研究挑战了这一观点。在通常经历低积极情感（PA）的个体中，相对于有限范围的积极情感体验，在一阵阵快乐和明显的快感缺乏之间摇摆可能与更好的行为健康有关。因此，我们测试了以下假设：通过 8 天强化重复生态瞬时评估 (EMA) 捕获的 PA 平均水平将调节 EMA 测量的 PA 变异性与带幼儿的职业母亲 (N= 202) 摄入时测量的行为健康之间的关联，而该人群有可能经历反复的压力和奖励引起的 PA 变化。混合效应位置尺度模型解析了 PA 均值和变异性的方差，这些模型用于与抑郁症状、焦虑和饮酒相关的受试者水平回归模型。 PA 平均值调节 PA 变异性与抑郁症状（交互作用：β=.20，p=.02）和饮酒频率（交互作用：β=.22，p=.02）的关联。在较高的 PA 平均水平下，PA 变异性与抑郁症状和饮酒水平呈正相关，而在低平均 PA 水平下，PA 变异性与抑郁症状和饮酒量呈负相关。 PA 平均值×变异性对于焦虑和酗酒而言，交互作用并不显着。我们的结论是：(a) 影响平均值 × 变异性交互作用的强化纵向模型可以为精神病理学研究提供增量信息；(b) PA 波动性并不单方面表明行为健康状况不佳； (c) 对 PA 波动作用的细致入微的视角可能有利于职业母亲的临床服务。
Affective volatility (ie, variability) is typically conceptualized as a marker of poor mental and behavioral health. The current research challenges this notion. Among individuals who typically experience low positive affect (PA), vacillation between bouts of joy and marked anhedonia may be associated with better behavioral health relative to a restricted range of PA experience. We therefore tested the hypothesis that mean levels of PA captured via an 8-day intensive repeated Ecological Momentary Assessment (EMA) would moderate the association of EMA-measured PA variability with behavioral health measured at intake among working mothers (N= 202) with young children—a population at risk for experiencing repeated stress-and reward-induced PA changes. Mixed-effects location scale modeling parsed variance in PA mean and variability, which were used in subject-level regression models of associations with depressive symptoms, anxiety, and alcohol use. PA mean moderated the associations of PA variability with depressive symptoms (Interaction: β=. 20, p=. 02) and alcohol consumption frequency (Interaction: β=. 22, p=. 02). PA variability and depressive symptom and alcohol consumption levels were positively associated at higher PA mean levels, whereas PA variability was inversely associated with depressive symptom and alcohol consumption at low mean PA. PA Mean× Variability Interactions were not significant for anxiety and binge drinking. We conclude that (a) intensive longitudinal modeling of Affect Mean× Variability Interaction effects may provide incremental information in psychopathology research;(b) PA volatility does not unilaterally indicate poor behavioral health; and (c) a nuanced perspective on the role of PA volatility may benefit clinical services for working mothers.
