Cognitive training designed to recalibrate maladaptive aspects of cognitive-affective processing associated with the presence of emotional disorder can deliver clinical benefits. This study examined the ability of an integrated training in self-distancing and perspective broadening (SD-PB) with respect to distressing experiences to deliver such benefits in individuals with a history of recurrent depression (≥3 prior episodes), currently in remission. Relative to an overcoming avoidance (OA) control condition, SD-PB: a) reduced distress to upsetting memories and to newly encountered events, both during training when explicitly instructed to apply SD-PB techniques, and after-training in the absence of explicit instructions; b) enhanced capacity to self-distance from and broaden perspectives on participants' experiences; c) reduced residual symptoms of depression. These data provide initial support for SD-PB as a low-intensity cognitive training providing a spectrum of cognitive and affective benefits for those with recurrent depression who are at elevated risk of future episodes.
旨在重新校准与情绪障碍相关的认知-情感加工的适应不良方面的认知训练可以带来临床益处。本研究考察了一种将自我疏离和视角拓宽(SD-PB)相结合的训练对于痛苦经历的作用,以探究其能否为有复发性抑郁症病史(既往发作≥3次)且目前处于缓解期的个体带来此类益处。相对于克服回避(OA)对照条件,SD-PB训练:a)在训练期间明确要求应用SD-PB技术时,以及训练后无明确指示的情况下,均能减轻对令人不安的记忆和新遇到事件的痛苦感受;b)增强了参与者从自身经历中自我疏离并拓宽视角的能力;c)减轻了抑郁的残留症状。这些数据为SD-PB作为一种低强度认知训练提供了初步支持,该训练能为有复发性抑郁症且未来发作风险较高的个体带来一系列认知和情感益处。
