Impulsivity is a core feature in patients with traumatic brain injury (TBI). The aim of the study is to investigate how a specific dimension of impulsivity, namely urgency (the tendency to act rashly when distressed), might shed new light on the aetiology of compulsive buying proneness in patients with TBI and to explore how urgency and compulsive buying relate to the burden perceived by the caregivers.
Caregivers of 74 patients with TBI were given 3 questionnaires in order to assess their subjective burden as well as patients' impulsivity and compulsive buying proneness.
Both urgency and compulsive buying tendencies significantly increased after TBI. Furthermore, path analyses revealed that current urgency was both directly and indirectly related to the subjective burden perceived by the caregivers, and this indirect pathway was mediated by compulsive buying.
Urgency plays a central role in understanding specific problematic behaviours after TBI and their impact on caregivers. These findings are discussed in light of the cognitive processes underlying the urgency component of impulsivity in relation to the occurrence of compulsive buying behaviours after TBI.
冲动是创伤性脑损伤（TBI）患者的核心特征之一。本研究旨在探讨冲动的一个特定维度——即紧迫感（在感到痛苦时草率行事的倾向），如何为 TBI 患者强迫性购买倾向的病因提供新的见解，并探讨紧迫感和强迫性购买与照顾者感知到的负担之间的关系。
为 74 名 TBI 患者的照顾者提供了 3 份问卷，以评估他们的主观负担以及患者的冲动性和强迫性购买倾向。
TBI 后，紧迫感和强迫性购买倾向均显著增加。此外，路径分析显示，当前的紧迫感与照顾者感知到的主观负担直接相关，且这种间接途径是由强迫性购买介导的。
紧迫感在理解 TBI 后特定的问题行为及其对照顾者的影响方面起着核心作用。这些发现是在与 TBI 后强迫性购买行为相关的冲动紧迫感成分的认知过程的基础上进行讨论的。
