积极情绪（PA）减弱对压力的消极反应；然而，PA 的这种适应性功能很少在以更极端的情感反应为特征的精神疾病中进行研究。我们在患有社交焦虑症（SAD）（一种以 NA 升高和 PA 减弱为特征的疾病）的参与者和非 SAD 对照受试者中测试了 PA 和负面情绪 (NA) 与焦虑反应性的明显关联。主要诊断为 SAD 的成年人 (n=71) 和没有精神病史的成年人 (n=36) 在过去一周内评估了他们的 PA 和 NA，并暴露在实验室压力源中，他们在其中就一个有争议的话题发表了视频录制的演讲。焦虑反应性是根据演讲前的预期焦虑以及演讲期间观察者评定的焦虑相关行为来评估的。在所有参与者中，较高的 PA 显着预测较低的预期焦虑和较少的焦虑相关行为，超出 NA 水平；较低的 NA 可以显着预测预期焦虑的减弱，但不能预测超出 PA 水平的焦虑相关行为。对于NA特别升高的个体以及患有SAD的个体而言，PA与应激反应性之间的关联比没有的个体减弱。 PA 可以防止对社会压力的负面反应；然而，理论模型和临床应用应考虑 PA 和 NA 在调节应激反应性方面可能的相互作用。
Positive affect (PA) attenuates negative reactivity to stress; however, this adaptive function of PA is seldom studied in psychiatric conditions characterized by more extreme forms of affective responding. We tested distinct associations of PA and negative affect (NA) with anxiety reactivity in participants with social anxiety disorder (SAD)—a condition characterized by heightened NA and diminished PA—and non-SAD control subjects. Adults with a principal diagnosis of SAD (n=71) and those without a psychiatric history (n=36) rated their PA and NA during the past week, and were exposed to a laboratory stressor wherein they delivered a video-recorded speech on a controversial topic. Anxiety reactivity was assessed in terms of anticipatory anxiety prior to the speech, and observer-rated anxiety-related behavior during the speech. Across all participants, higher PA significantly predicted lower anticipatory anxiety and less anxiety-related behavior, beyond level of NA; lower NA significantly predicted attenuated anticipatory anxiety, but not anxiety-related behavior, beyond level of PA. The association between PA and stress reactivity was diminished for individuals with especially elevated NA, as well as for individuals with SAD compared to those without. PA may be protective against negative reactivity to social stress; however, theoretical models and clinical applications should consider possible interactive effects of PA and NA in modulating stress reactivity.
