Clinical perfectionism is associated with various cognitive processes including performance monitoring and emotion regulation. This exploratory study analyzed neurological data from a randomized controlled trial for clinical perfectionism that compared acceptance and commitment therapy (ACT) to a waitlist control. The objective was to assess the effect of ACT on neural activation. Twenty-nine participants underwent a functional near-infrared spectroscopy assessment during which they completed behavioral tasks designed to elicit error detection and error generation at pre- and posttreatment. The hemodynamic response function (HRF) in the dorsolateral prefrontal cortex, dorsomedial prefrontal cortex, and right inferior parietal lobe was analyzed using mixed effects models. In all areas, we found reductions or smaller increases in the total HRF for experimental tasks from pre-to posttreatment in the ACT condition compared to the waitlist condition. Decreases in total oxygenated hemoglobin are consistent with diminished recruitment of neurons in response to previously emotionally salient stimuli, possibly representing greater cognitive processing efficiency. Our preliminary findings tentatively support the processes of change posited by the theory underlying ACT and highlight the need for more precise methodology in neurological assessment to adequately evaluate how treatment affects neurological function. Limitations include lack of an active comparison condition and behavioral data.

接受和承诺治疗对临床完美主义中神经激活的影响的初步研究

临床完美主义与各种认知过程相关,包括绩效监测和情绪调节。这项探索性研究分析了来自临床对照的随机对照试验的神经系统数据,该试验将接受和承诺治疗(ACT)与候补对照进行了比较。目的是评估ACT对神经激活的作用。29名参与者进行了功能近红外光谱评估,在此评估过程中,他们完成了旨在在治疗前和后引起错误检测和错误产生的行为任务。使用混合效应模型分析了背外侧前额叶皮层,背侧前额叶皮层和右下顶叶的血流动力学反应功能(HRF)。在所有领域 我们发现,与等待列表条件相比,在ACT条件下从治疗前到治疗后,实验任务的总HRF减少或减少。总含氧血红蛋白的减少与对先前情绪突出刺激的神经元募集减少有关,这可能表示更高的认知加工效率。我们的初步发现暂定支持ACT理论所提出的变化过程,并强调需要在神经学评估中采用更精确的方法来充分评估治疗如何影响神经功能。局限性包括缺乏有效的比较条件和行为数据。总含氧血红蛋白的减少与对先前情绪突出刺激的神经元募集减少有关,这可能表示更高的认知加工效率。我们的初步发现暂定支持ACT理论所提出的变化过程,并强调需要在神经学评估中采用更精确的方法来充分评估治疗如何影响神经功能。局限性包括缺乏有效的比较条件和行为数据。总含氧血红蛋白的减少与对先前情绪突出的刺激做出反应的神经元募集减少有关,这可能表示更高的认知加工效率。我们的初步发现暂定支持ACT理论所提出的变化过程,并强调需要在神经学评估中采用更精确的方法来充分评估治疗如何影响神经功能。局限性包括缺乏有效的比较条件和行为数据。我们的初步发现暂定支持ACT理论所提出的变化过程,并强调需要在神经学评估中采用更精确的方法来充分评估治疗如何影响神经功能。局限性包括缺乏有效的比较条件和行为数据。我们的初步发现暂定支持ACT理论所提出的变化过程,并强调需要在神经学评估中采用更精确的方法来充分评估治疗如何影响神经功能。局限性包括缺乏有效的比较条件和行为数据。
