项目摘要
DESCRIPTION (provided by applicant): One of the most common secondary complications of traumatic brain injury (TBI) is substance abuse. Substance abuse affects health and function after TBI, and has been associated with worse outcomes. Deficits in self-regulation are common to both TBI and substance abuse, and may be one source of the poorer outcomes. Researchers have been hampered in their ability to study the effects of self-regulation deficits due to difficulties with measurement. Bechara's Gambling Task may provide the ideal analog for studying self-regulation and sensitivity to contingencies in persons with TBI and substance abuse, as it was originally developed to study the effects of focal damage to the orbitofrontal cortex and has been used with persons with substance use disorders. Performance on this task has shown persons with lesions in the orbitofrontal cortex to behave based on immediate consequences, without regard to the effects of their choices on future consequences. Some persons with substance use disorders show similar performance, while others appear to be extremely sensitive to rewards and under-responsive to punishment. The current project seeks to determine if the Gambling Task can be used to study self-regulation in persons with both TBI and a substance use disorder, given that the former is associated with more diffuse deficits than the group with focal lesions previously studied. Specifically, this project aims to: 1) Identify the impediments posed by co-existing cognitive deficits when using Bechara's Gambling Task to evaluate self-regulation and sensitivity to contingencies in persons with TBI; 2) Identify methods of scoring performance and describing possible underlying processes which can assist with discriminating between the performance of controls, persons with TBI only, persons with a substance use disorders only, and persons with both disorders; and 3) Determine the sample size required to detect meaningful differences in performance on the Gambling Task between controls, persons with TBI, persons with substance use disorders, and persons with both disorders.
描述(由申请人提供):创伤性脑损伤(TBI)最常见的继发性并发症之一是药物滥用。 药物滥用影响TBI后的健康和功能,并与更糟糕的结果相关。 自我调节的缺陷是TBI和药物滥用的共同点,可能是不良结果的来源之一。由于难以测量,研究人员在研究自我调节缺陷的影响方面受到了阻碍。Bechara的赌博任务可能提供了理想的模拟研究自我调节和敏感性的突发事件的人与TBI和药物滥用,因为它最初是开发来研究局灶性损伤的影响眶额皮质,并已用于与物质使用障碍的人。这项任务的表现表明,眶额皮层有损伤的人的行为基于即时后果,而不考虑他们的选择对未来后果的影响。一些患有药物使用障碍的人表现出类似的表现,而另一些人似乎对奖励极其敏感,对惩罚反应迟钝。目前的项目旨在确定赌博任务是否可用于研究TBI和物质使用障碍患者的自我调节,因为前者与以前研究的局灶性病变组相比具有更多的弥漫性缺陷。具体而言,本项目旨在:1)确定当使用Bechara的赌博任务来评估TBI患者的自我调节和对突发事件的敏感性时,共存的认知缺陷所造成的障碍; 2)确定对表现进行评分并描述可能的潜在过程的方法,这些方法可以帮助区分对照、仅患有TBI的人、仅患有物质使用障碍的人的表现,以及3)确定检测对照组、TBI患者、物质使用障碍患者和两种障碍患者之间在赌博任务上表现的有意义差异所需的样本量。
