Tendencies to attend to threatening cues in the environment and to interpret ambiguous situations with negative/hostile intent maintain and may even precipitate internalizing and externalizing problems in young people with a history of maltreatment. Challenging maladaptive information-processing styles using cognitive bias modification (CBM) training may reduce symptoms.
To investigate the acceptability of CBM training in nine young people attending alternate education provision units in the UK, and 10 young people living in out-of-home care institutions in Nepal with a history of maltreatment.
CBM training consisted of five sessions of training over a 2-week period; each training session consisted of one module targeting attention biases and one module targeting interpretation biases for threat. A feedback form administered after training measured acceptability. Pre- and post-intervention measures of internalizing and externalizing symptoms were also taken.
Most young people (89%) found the training helpful and 84% found the training materials realistic. There were reductions in many symptom domains, but with individual variation. Although limited by the lack of a control condition, we established generalizability of acceptability across participants from two cultural settings.
Replication of these findings in larger feasibility randomized controlled trials with measures of attention and interpretation bias before and after intervention, are needed to assess the potential of CBM in reducing anxiety symptoms and its capacity to engage targeted mechanisms.
在有虐待史的年轻人中,倾向于关注环境中的威胁线索,并以消极/敌对的意图来解释模棱两可的情况,这可能会维持甚至加剧内化和外化问题。使用认知偏差修正(CBM)训练来挑战适应不良的信息处理方式,可能会减轻症状。
调查认知偏差修正训练在英国九名接受替代教育服务的年轻人和十名尼泊尔寄养机构中有虐待史的年轻人中的可接受性。
CBM 训练包括为期两周的五节训练课程;每节训练课程包括一个针对注意力偏差的模块和一个针对威胁解释偏差的模块。训练后,会通过一份反馈表来衡量可接受性。干预前后还会进行内化和外化症状的测量。
大多数年轻人(89%)认为训练有帮助,84%的年轻人认为训练材料真实。许多症状领域都有所减少,但个体差异较大。尽管由于缺乏对照组,我们在来自两个文化背景的参与者中建立了可接受性的推广性。
需要在更大的可行性随机对照试验中复制这些发现,并在干预前后测量注意力和解释偏差,以评估 CBM 在减轻焦虑症状方面的潜力及其对目标机制的影响。
