Investigating the cognitive mechanisms of decentring and its impact on emotional reactivity in adolescence.

去中心化是许多基于正念的疗法的一个特点，但它作为一种结构，以及它的认知机制，都缺乏清晰度。新出现的证据表明，提高一个人建立非中心视角的能力，可以调节正念训练与临床结果之间的关系。我们将重点讨论去中心化，因为它在许多第三波疗法中似乎是一种关键的积极机制。本研究的目的是：(i)描述分散与青少年情绪调节之间的关系，（ii）确定分散的认知相关性，（iii）调查一旦了解认知机制，是否可以改进分散训练技术。将进行两个项目：第一部分-一个大型项目，描述年轻人的特质分散能力及其对自我报告的情绪调节的影响。我还会进行一些认知评估来确定认知的哪些方面可以预测特质分散能力。第2部分-基于第1部分的证据，以及ECMH集团正在进行的研究，我将提供一个为期5周的强化分散培训计划，以调查第1部分中确定的认知机制。我还将测量这种干预对情绪调节策略的影响。将招募具有高度焦虑抑郁特征的青少年样本（N=60），并提供为期五周的集中分散培训计划。

Decentring, a feature of many mindfulness-based therapies, lacks clarity as a construct, and in terms of its cognitive mechanisms. Emerging evidence suggests that improving ones' ability to instate a decentred perspective mediates the relationship between mindfulness training and clinical outcomes. Decentring will be focused on due to its existence as a seemingly key active mechanism in many third wave therapies. The objectives of this research are: (i) To characterise the relationship between decentring and emotional regulation in adolescents, (ii) Identify the cognitive correlates of decentring, (iii) Investigate whether decentring training techniques can be improved once cognitive mechanisms are understood. Two projects will be undertaken Part 1 - A large-scale project characterising trait decentring abilities in young people, and their impact on self-reported emotion regulation. I will also administer a number of cognitive assessments to determine which aspects of cognition predict trait decentring ability. Part 2 - Based on the evidence of Part 1, and ongoing research in the ECMH Group, I will deliver an intensive 5-week decentring training programme to investigate cognitive mechanisms identified in Part 1. I will also measure the impact this intervention has on emotion regulation strategies. A sample of adolescents (N=60) with elevated anxious-depressive traits will be recruited, and an intensive five week decentring training programme will be delivered.
