Distress has been assumed to result from exposure to repetitive thought (RT). However, if RT is viewed as internally generated stressors, both exposure and affective reactivity to RT could play roles in generating distress.
Three studies (young adults, N=99; midlife women, N=111; older adults, N=159) assessed exposure and reactivity to daily RT and tested whether neuroticism was related to individual differences in both exposure and affective reactivity.
Across all 3 studies, reactivity effects on depressive symptoms exceeded those of exposure to RT, and neuroticism was associated with more exposure and greater affective reactivity. Furthermore, RT exposure and reactivity accounted for most when not all of the relationship between neuroticism and depressive symptoms.
Further consideration of both exposure and affective reactivity to RT can not only increase the explanatory power of this construct but also suggest effective targets for intervention.
人们一直认为痛苦是由反复思考（RT）所致。然而，如果将反复思考视为内在产生的压力源，那么对反复思考的暴露以及情感反应都可能在产生痛苦方面发挥作用。
三项研究（年轻成年人，N = 99；中年女性，N = 111；老年人，N = 159）评估了对日常反复思考的暴露和反应，并测试了神经质是否与暴露和情感反应方面的个体差异有关。
在所有三项研究中，对抑郁症状的反应效应超过了对反复思考的暴露效应，并且神经质与更多的暴露和更大的情感反应相关。此外，反复思考的暴露和反应在神经质与抑郁症状之间的关系中占了大部分（即便不是全部）。
进一步考虑对反复思考的暴露和情感反应，不仅可以提高这一概念的解释力，还能为干预提供有效的目标。
