Emotion dysregulation and the experience of fatigue have both been linked to the maintenance of substance use. However, limited empirical data has evaluated individual differences in these constructs in terms of e-cigarette use expectancies. The present study examined a theoretically relevant model focused on whether the experience of more severe fatigue explains, in part, the relation between individual differences in emotion dysregulation and positive and negative e-cigarette expectancies among 525 adult e-cigarette users (50.9% female, Mage = 35.25 years, SD = 10.10). It was hypothesized that emotion dysregulation, via fatigue severity, would significantly predict greater positive and negative e-cigarette expectancies, which was examined in two separate mediation models. Fatigue severity significantly explained, in part, the relation between emotion dysregulation and positive (b = 0.02, CI [0.01, 0.02]) and negative expectancies of e-cigarette use (b = 0.02, 95% CI [0.02, 0.03]). The current findings suggest that the experience of fatigue helps explain the relation between emotion dysregulation and positive and negative e-cigarette expectancies among adult e-cigarette users. Future work is needed to explicate how reducing fatigue severity in the context of emotion dysregulation may change expectancies about e-cigarette expectancies.

情绪失调、疲劳和电子烟期望


情绪失调和疲劳经历都与物质使用的维持有关。然而，有限的经验数据评估了这些结构在电子烟使用预期方面的个体差异。本研究检验了一个理论上相关的模型，重点关注 525 名成年电子烟使用者（50.9% 为女性，法师 = 35.25 岁，SD = 10.10)。据推测，由于疲劳严重程度而导致的情绪失调将显着预测更大的积极和消极电子烟预期，这一点在两个独立的中介模型中进行了检验。疲劳严重程度在一定程度上显着解释了情绪失调与电子烟使用的积极预期（b = 0.02，CI [0.01，0.02]）和消极预期（b = 0.02，95% CI [0.02，0.03]）之间的关系。目前的研究结果表明，疲劳的经历有助于解释成年电子烟使用者的情绪失调与积极和消极的电子烟预期之间的关系。未来的工作需要阐明在情绪失调的情况下减轻疲劳严重程度如何可能改变对电子烟的期望。
