Impaired awareness of errors is common following traumatic brain injury (TBI) and can be a barrier to successful rehabilitation. The objective of this study was to develop and evaluate a computer-based intervention programme aimed at improving error awareness in individuals with TBI. A further aim was to explore its effects on metacognitive awareness and variability of performance. Participants were 11 individuals with TBI and impaired error awareness who performed a sustained attention task twice-weekly for four weeks. The intervention consisted of audio-visual feedback-on-errors during the sustained attention task. Six participants received audio-visual feedback-on-error, five did not receive feedback. Emergent and metacognitive awareness were measured pre- and post-intervention. Between-groups comparisons of emergent awareness from pre- to post-intervention showed that audio-visual feedback-on-error improved emergent awareness compared to no feedback-on-error. Some changes in metacognitive awareness of executive behaviours as a result of feedback were observed. Audio-visual feedback-on-error improved emergent awareness in individuals with TBI following a four-week/eight-session intervention. This improvement was not observed in the no-feedback group. This pilot intervention is not a stand-alone treatment but it has potential to be usefully incorporated into cognitive or clinical rehabilitation programmes to improve emergent awareness.
创伤性脑损伤（TBI）后错误意识受损很常见，可能会成为成功康复的障碍。本研究的目的是开发并评估一个基于计算机的干预项目，旨在提高创伤性脑损伤患者的错误意识。另一个目的是探索其对元认知意识和表现变异性的影响。参与者为11名创伤性脑损伤且错误意识受损的个体，他们每周进行两次持续注意力任务，共持续四周。干预措施包括在持续注意力任务期间提供关于错误的视听反馈。6名参与者接受了关于错误的视听反馈，5名未接受反馈。在干预前后测量了突发意识和元认知意识。干预前后组间突发意识比较表明，与无错误反馈相比，有错误的视听反馈提高了突发意识。观察到由于反馈，执行行为的元认知意识有一些变化。经过四周/八次干预后，有错误的视听反馈提高了创伤性脑损伤个体的突发意识。在无反馈组中未观察到这种改善。这项试点干预不是一种独立的治疗方法，但有可能有效地纳入认知或临床康复项目中，以提高突发意识。
