摘要

研究表明,述情障碍和冲动(部分)解释了创伤性脑损伤(TBI)患者的攻击行为,但这些研究都没有按照建议同时使用问卷和基于绩效的测量方法,也没有同时调查冲动和述情障碍。因此,现有的研究可能遗漏了述情障碍和冲动的部分结构,并且没有全面评估这两个结构在TBI和攻击性之间关系中的中介作用。N的样本 = 281名被监禁者从荷兰监狱机构招募,完成了Buss-Perry攻击性问卷(攻击性)、BIS-11(冲动性)和多伦多述情障碍量表-20(述情障碍)问卷,以及停止信号任务和情绪识别范式。使用结构方程模型进行了几次多重中介分析,以评估攻击因果理论模型的可行性。最终计划的模型是与数据拟合良好的原始模型(比较拟合指数 > 0.95,近似均方根误差和标准化均方根残差

Mediating effects of impulsivity and alexithymia in the association between traumatic brain injury and aggression in incarcerated males

Studies suggest both alexithymia and impulsivity (partially) explain aggressive behavior in traumatic brain injury (TBI) patients, but none of these studies use both questionnaire and performance-based measures as recommended, nor simultaneously investigate both impulsivity and alexithymia. The available studies therefore likely miss part of the constructs of alexithymia and impulsivity, and do not comprehensively assess the mediating effects of both constructs in the relationship between TBI and aggression. A sample of N = 281 incarcerated individuals were recruited from Dutch penitentiary institutions, and completed the Buss Perry Aggression Questionnaire (aggression), BIS-11 (impulsivity) and Toronto Alexithymia Scale-20 (alexithymia) questionnaires, as well as a stop-signal task and an emotion recognition paradigm. Several multiple mediation analyses were conducted using structural equation modelling, to assess the viability of a causal theoretical model of aggression. The final planned models were the original models with a good fit with the data (comparative fit index > 0.95, root mean square error of approximation and Standardized root mean square residual < 0.05), and results indicate that only questionnaire-based impulsivity mediated the relationship between TBI and aggression. TBI was unrelated to alexithymia, stop-signal or emotion recognition performance. Aggression was predicted by both alexithymia and impulsivity, but not by the performance measures. Post hoc analyses shows that alexithymia moderates the relationship between impulsivity and aggression. These results imply that aggressive incarcerated individuals showing impulsive behavior should be screened for TBI, since TBI is often overlooked or misdiagnosed, and indicate that both impulsivity and alexithymia are potential focus points for aggression reduction treatment in TBI patients.

期刊介绍: Aggressive Behavior will consider manuscripts in the English language concerning the fields of Animal Behavior, Anthropology, Ethology, Psychiatry, Psychobiology, Psychology, and Sociology which relate to either overt or implied conflict behaviors. Papers concerning mechanisms underlying or influencing behaviors generally regarded as aggressive and the physiological and/or behavioral consequences of being subject to such behaviors will fall within the scope of the journal. Review articles will be considered as well as empirical and theoretical articles. Aggressive Behavior is the official journal of the International Society for Research on Aggression.
