PRIMARY OBJECTIVE
This study aimed to identify and characterize profiles of executive functions (EF) following traumatic brain injury (TBI).
RESEARCH DESIGN
The sample was comprised of 84 adult outpatients with mild and moderate/severe TBI who were assessed by means of a battery of EF tasks. A Hierarchical Cluster analysis was performed with tasks Z-scores. Clusters were compared by means of ANOVA and Chi-square analyses.
MAIN OUTCOMES AND RESULTS
Three clusters were characterized by deficits in: (1) inhibition, flexibility and focused attention; (2) inhibition, flexibility, working memory and focused attention; and (3) no expressive executive deficits. Clusters did not differ in clinical or demographical variables.
CONCLUSIONS
The first cluster replicated findings of previous studies on TBI EF profiles. IT is suggested that TBI rehabilitation studies of EF must select participants by their EF profile rather than for clinical or demographical variables.
主要目的
本研究旨在识别和描述创伤性脑损伤（TBI）后执行功能（EF）的特征。
研究设计
样本包括84名患有轻度和中度/重度TBI的成年门诊患者，他们通过一系列EF任务进行评估。对任务Z分数进行分层聚类分析。通过方差分析和卡方分析对聚类进行比较。
主要结果
三个聚类的特征分别为：（1）抑制、灵活性和集中注意力缺陷；（2）抑制、灵活性、工作记忆和集中注意力缺陷；（3）无表达性执行功能缺陷。聚类在临床或人口统计学变量上没有差异。
结论
第一个聚类重复了先前关于TBI EF特征研究的结果。建议TBI EF的康复研究必须根据EF特征而非临床或人口统计学变量来选择参与者。
