This study was designed to explore the behavioral nature of pragmatic impairment following severe traumatic brain injury (TBI) and to evaluate the contribution of executive skills to the experience of pragmatic difficulties after TBI.
Participants were grouped into 43 TBI dyads (TBI adults and close relatives) and 43 control dyads. All TBI participants had sustained severe injury (mean posttraumatic amnesia duration = 45.19 days, SD = 39.15) due to a moving vehicle-related trauma. A minimum of 2 years had elapsed since injury (M = 5.36 years, SD = 3.61). The La Trobe Communication Questionnaire (LCQ; Douglas, O'Flaherty, & Snow, 2000) was administered to all participants. Measures of executive function included the following: the FAS verbal fluency task (Spreen & Benton, 1969), the Speed and Capacity of Language Processing test (Baddeley, Emslie, & Nimmo-Smith, 1992), and the Rey Auditory Verbal Learning Task (Rey, 1964).
Perceptions of TBI participants and their relatives were significantly correlated (r = .63, p < .001) and significantly different from those of controls, F(1, 84) = 37.2, p < .001. Pragmatic difficulties represented violations in 3 domains of Grice's (1975) Cooperative Principle (Quantity, Relation, and Manner), and executive function measures predicted 37% (32% adjusted) of the variability in LCQ scores.
The study demonstrates evidence of a significant association between executive impairment and the pragmatic communication difficulties experienced by individuals with TBI.
本研究旨在探讨严重创伤性脑损伤（TBI）后语用障碍的行为特征，并评估执行技能对 TBI 后语用困难体验的贡献。
将参与者分为 43 对 TBI 患者（TBI 患者及其近亲）和 43 对对照组。所有 TBI 患者均因与行驶车辆相关的创伤而遭受严重损伤（平均创伤后遗忘期=45.19 天，SD=39.15）。受伤后至少 2 年（M=5.36 年，SD=3.61）。所有参与者均接受了拉筹伯沟通问卷（LCQ；Douglas、O'Flaherty 和 Snow，2000）评估。执行功能的测量包括：FAS 言语流畅性任务（Spreen 和 Benton，1969）、语言处理速度和能力测试（Baddeley、Emslie 和 Nimmo-Smith，1992）以及 Rey 听觉言语学习任务（Rey，1964）。
TBI 患者及其亲属的感知呈显著相关（r=.63，p<.001），与对照组的感知显著不同，F(1,84)=37.2，p<.001。语用困难表现为违反了 Grice（1975）合作原则的 3 个领域（数量、关系和方式），执行功能测量预测了 LCQ 得分的 37%（调整后 32%）的可变性。
该研究证明了 TBI 个体的执行功能损伤与语用沟通困难之间存在显著关联。
