OBJECTIVE: This randomized controlled trial investigated self-reported affective and physiological responses during ImRs.
METHODS: Seventy-seven patients with social anxiety disorder (SAD) were randomly assigned to a single session of ImRs or a control intervention (recall and discussion of the memory) targeting an aversive social memory. Heart rate (HR) and heart rate variability (HRV) were assessed during and post hoc ratings of positive and negative feelings after baseline and the intervention phases.
RESULTS: Relative to the control intervention, ImRs resulted in an initial increase in negative feelings from baseline to phase 1 and a following larger (phase 1 to phase 2) and more stable (phase 2 to phase 3) decrease in negative feelings/increase in positive feelings. On the physiological level, during ImRs compared to the control intervention, mean HR was significantly higher during phase 1 and HRV during phase 3, each compared to baseline.
CONCLUSIONS: These results provide further information about the specific sequence of emotional responses on different response levels during ImRs, being consistent with known theories of emotional processing and supposed mechanisms of ImRs.
目的:这项随机对照试验研究了在ImR过程中自我报告的情感和生理反应。
方法:将77名社交焦虑症(SAD)患者随机分配到单一疗程的ImR或针对厌恶性社交记忆的对照干预(回忆和讨论记忆)。心率(HR)和心率变异性(HRV)在基线和干预阶段后对正面和负面情绪进行了评估。
结果:相对于对照干预,ImR导致负面情绪从基线到第1阶段的初始增加,以及随后更大的(第1阶段到第2阶段)和更稳定的(第2阶段到第3阶段)负面情绪的减少/正面情绪的增加。在生理层面上,在与对照干预相比的IMR期间,与基线相比,1期平均HR和3期平均HRV均显著较高.
结论:这些结果提供了有关ImR期间不同反应水平的情绪反应的特定序列的进一步信息,与已知的情绪加工理论和假设的ImR机制相一致。
