This study investigated the effects of post-event processing on intrusive images following exposure to stress. It was hypothesized that ruminative activity, especially verbal worry about a stressor leads to an incubation of intrusions. Five groups which differed in the use of post-event processing strategies were used to test for a hypothesized co-joint mechanism underlying the effect. Worrying about a stressor for a period of 4 min after exposure led to significantly more intrusions in the next 3 days than a settle-down control condition. The strategies of imaging about the stressor, distraction, and worrying about usual concerns, produced a significant incremental linear pattern of intrusions across these groups. The pattern of results was as predicted by a co-joint model in which incubation results from 'tagging' of memories and blocked emotional processing. The clinical implications of these findings are briefly discussed.
本研究调查了事件后处理对暴露于压力后侵入性意象的影响。研究假设是，反复思考活动，尤其是对压力源的言语担忧会导致侵入的持续增加。使用五组在事件后处理策略使用上存在差异的被试来测试一种假设的联合机制，该机制是这种影响的基础。暴露后对压力源担忧4分钟，在接下来的3天里比平静对照条件下产生了显著更多的侵入。对压力源进行意象、分散注意力以及对日常担忧进行担忧等策略，在这些组中产生了侵入的显著递增线性模式。结果模式正如联合模型所预测的那样，即持续增加是由记忆的“标记”和受阻的情绪处理导致的。简要讨论了这些发现的临床意义。
