主要目标：比较创伤性脑损伤（TBI）患者与对照组的攻击性亚型，探讨社会期望的作用。设计：准实验，配对参与者设计。方法和程序：69名参与者被纳入本研究。样本包括TBI组（n = 24）、脊髓损伤（SCI）组（n = 21）和匹配的健康志愿者的未损伤（UI）组（n = 24）。参与者被给予自我报告的攻击性，社会可取性和冲动性的措施。主要结果和结果：使用标准化规范，25 - 39%的TBI参与者被归类为高平均值-非常高的愤怒和35 - 38%的高平均值-非常高的言语攻击。其他评分者认为TBI参与者的言语攻击性明显高于SCI和UI参与者。在身体攻击方面，两组之间没有差异。TBI组的冲动性水平也高于SCI和UI组。结论：冲动性言语攻击和愤怒是脑损伤后的主要攻击特征。在TBI后的极端情况下可能会出现身体攻击，但在这一人群中总体上不太突出。社会可取性，以前被忽视的研究TBI侵略，出现作为一个有影响力的变量，应在未来的TBI研究考虑。
Primary objective: To compare patients with traumatic brain injury ( TBI) with controls on sub-types of aggression and explore the role of social desirability.Design: Quasi- experimental, matched-participants design.Methods and procedures: Sixty- nine participants were included in the study. The sample comprised a TBI group ( n = 24), a spinal cord injury ( SCI) group (n = 21) and an uninjured (UI) group of matched healthy volunteers ( n = 24). Participants were given self-report measures of aggression, social desirability and impulsivity. Sixty- one independent 'otherraters' were nominated, who rated participant pre-morbid and post- morbid aggression.Main outcomes and results: Using standardized norms, 25 - 39% of participants with TBI were classified as high average - very high on anger and 35 - 38% as high average - very high on verbal aggression. Other- raters rated participants with TBI as significantly higher on verbal aggression than SCI and UI participants. There were no differences between the groups on physical aggression. The TBI group also had higher levels of impulsivity than SCI and UI groups. Social desirability was a highly significant predictor of self- reported aggression for the entire sample.Conclusions: Impulsive verbal aggression and anger are the principal aggressive traits after brain injury. Physical aggression may present in extreme cases after TBI, but appears less prominent overall in this population. Social desirability, previously overlooked in research examining TBI aggression, emerged as an influential variable that should be considered in future TBI research.
