Traumatic brain injury (TBI) frequently results in significant changes in physical, cognitive and emotional status. Outcomes after TBI may be related to accurate appraisal of these changes. This study examined the relationship between cognitive appraisal accuracy and psychosocial outcomes in TBI survivors.
Participants were male and female TBI survivors (n=103) who were at least 6 months post-injury and a family member of each survivor. Appraisal accuracy was assessed using self- and observer-report measures of perceived cognitive difficulties. Family members also completed a measure of psychosocial function. Hierarchical regression techniques were used to determine whether cognitive appraisal accuracy accounted for a significant proportion of variance in psychosocial outcomes.
Study findings indicated cognitive appraisal accuracy moderated the relationship between injury severity and aspects of psychosocial function.
The results suggest that brain injury outcomes may be improved when an individual is able to accurately assess limitations.
创伤性脑损伤（TBI）常常导致身体、认知和情绪状态发生显著变化。TBI后的结果可能与对这些变化的准确评估有关。本研究考察了TBI幸存者认知评估准确性与心理社会结果之间的关系。
参与者为受伤至少6个月后的TBI男性和女性幸存者（n = 103）以及每位幸存者的一名家庭成员。使用自我报告和观察者报告的感知认知困难测量方法来评估评估准确性。家庭成员还完成了一项心理社会功能测量。采用分层回归技术来确定认知评估准确性是否在心理社会结果的方差中占显著比例。
研究结果表明，认知评估准确性调节了损伤严重程度与心理社会功能方面之间的关系。
结果表明，当个体能够准确评估自身局限性时，脑损伤的结果可能会得到改善。
