Despite encouraging preliminary findings regarding the efficacy of mindfulness and acceptance-based treatments for a range of psychological presentations, we have yet to elucidate mechanisms of action within these treatments. One mechanism through which mindfulness may reduce psychological symptoms and promote functioning is enhancing emotional responding and regulation. In this study, we used multimodal assessment to examine the effects of a brief mindfulness intervention in a laboratory setting on emotional experiences and regulation in response to distressing, positive, and affectively mixed film clips. Although there were no condition (mindfulness vs. control) effects on reports of emotional response or difficulties in regulation after the distressing film clip, participants in the mindfulness condition reported significantly greater positive affect in response to the positive film. Additionally, participants in the mindfulness condition reported more adaptive regulation (approaching significance, medium to large effect size) in response to the affectively mixed clip and significantly less negative affect immediately after this clip, although not after a recovery period. No significant differences emerged between conditions on physiological measures (skin conductance and heart rate) throughout the study.
尽管有令人鼓舞的初步发现表明,正念和接纳为基础的治疗方法对一系列心理表现有效,但我们仍需阐明这些治疗方法中的作用机制。正念可能通过增强情绪反应和调节来减轻心理症状和促进功能的一种机制。在这项研究中,我们使用多模态评估在实验室环境下检查了一个简短的正念干预对情绪体验和对痛苦、积极和情感混合电影片段的调节的影响。尽管在痛苦的电影片段后,在情绪反应或调节困难的报告方面,没有条件(正念与对照)的影响,但在正念条件下的参与者对积极电影的积极情绪反应明显更大。此外,在正念条件下的参与者在情感混合片段的反应中表现出更适应的调节(接近显著,中等到大的效应大小),并且在这段片段后立即的负面情绪明显较少,尽管在恢复期后没有。在整个研究过程中,生理测量(皮肤电导和心率)在条件之间没有出现显著差异。
