: To investigate the nature and patterns of narrative discourse impairment in people with severe Traumatic Brain Injury (TBI) during early recovery.: A single image picture description task was administered to 42 participants with severe TBI at 3 and 6-months post-injury. The same task was administered to 37 control participants. Discourse samples were analyzed with measures of productivity, informativeness and story organization. The performance of people with TBI was compared with the control group at both 3 and 6 months, and the performance of the participants with TBI was also compared across the two time points. Individual patterns of performance were also examined.: Inferential analyses revealed significant differences between the control group and the group with TBI on informativeness at both time points and number of complete episodes at 3 months, but no significant differences for productivity measures. There was no significant change for the group with TBI between 3 and 6 months. However, individual improvement over time was observed.: People with TBI have discourse difficulties early post TBI that are also present at 6-months post-injury. In order to understand longer-term discourse recovery, it is necessary to examine participant patterns over further time points on this narrative task.
研究重度创伤性脑损伤(TBI)患者在早期恢复过程中叙事话语损伤的性质和模式。
对42名重度TBI患者在受伤后3个月和6个月进行了单张图像描述任务。对37名对照参与者进行了相同的任务。用产出率、信息性和故事组织性指标分析话语样本。在3个月和6个月时将TBI患者的表现与对照组进行比较,并且也对TBI患者在两个时间点的表现进行比较。还检查了个体表现模式。
推断分析显示,在两个时间点的信息性以及3个月时的完整情节数量方面,对照组和TBI组之间存在显著差异,但在产出率指标方面无显著差异。TBI组在3个月至6个月之间没有显著变化。然而,观察到个体随时间有所改善。
TBI患者在TBI后早期存在话语困难,这种困难在受伤后6个月时也存在。为了了解长期的话语恢复情况,有必要在这个叙事任务上进一步检查参与者在更多时间点的模式。
