Maladaptive emotion regulation (ER) strategies are important predictors of stress generation—the process by which individuals with certain traits are likely to experience higher levels of dependent (self-generated), but not independent (fateful), stressful life events. Positive affect (PA) dampening, the tendency to downregulate positive moods by reducing their intensity and duration, may weaken interpersonal ties and therefore increase vulnerability to stress generation, particularly in the interpersonal domain. The present study examined longitudinal associations between PA dampening and stress generation in an adolescent sample (N = 241, M_age = 15.9, 51.8% female) assessed at baseline and at follow-up 1.5 years later. Dampening was assessed with a self-report questionnaire and stress exposure was assessed using contextual threat-based interview methods. Preregistered analyses revealed that PA dampening did not prospectively predict episodic interpersonal or non-interpersonal dependent stress; instead, dampening was associated with greater episodic independent stress, inconsistent with the stress generation model. Higher dampening at baseline also predicted increases in chronic stress in both interpersonal and non-interpersonal domains over follow-up. Findings suggest that PA regulation strategies may contribute to sustained stressful contexts, rather than discrete life events.

适应不良的情绪调节（ER）策略是压力产生的重要预测因素，在这个过程中，具有某些特征的个体可能会经历更高水平的依赖（自我产生）而非独立（致命）的压力生活事件。积极情绪（PA）抑制，即通过降低积极情绪的强度和持续时间来下调积极情绪的倾向，可能会削弱人际关系，从而增加对压力产生的脆弱性，特别是在人际领域。本研究考察了青少年样本中 PA 抑制与压力产生之间的纵向关联（N  = 241，M_年龄） = 15.9，51.8% 女性）在基线和 1.5 年后随访时进行评估。通过自我报告问卷评估抑制作用，并使用基于情境威胁的访谈方法评估压力暴露。预先登记的分析显示，PA 抑制并不能前瞻性地预测偶发的人际或非人际依赖性压力；相反，阻尼与更大的偶发独立应力相关，这与应力产生模型不一致。基线时较高的抑制也预示着随访期间人际和非人际领域的慢性压力会增加。研究结果表明，PA 调节策略可能会导致持续的压力环境，而不是离散的生活事件。
