Difficulties in communication and social relationships present a formidable challenge for many people after traumatic brain injury (TBI). These difficulties are likely to be partially attributable to problems with emotion perception. Mounting evidence shows facial affect recognition to be particularly difficult after TBI. However, no attempt has been made to systematically estimate the magnitude of this problem or the frequency with which it occurs.
A meta-analysis is presented examining the magnitude of facial affect recognition difficulties after TBI. From this, the frequency of these impairments in the TBI population is estimated. Effect sizes were calculated from 13 studies that compared adults with moderate to severe TBI to matched healthy controls on static measures of facial affect recognition.
The studies collectively presented data from 296 adults with TBI and 296 matched controls. The overall weighted mean effect size for the 13 studies was -1.11, indicating people with TBI on average perform about 1.1 SD below healthy peers on measures of facial affect recognition. Based on estimation of the TBI population standard deviation and modeling of likely distribution shape, it is estimated that between 13% and 39% of people with moderate to severe TBI may have significant difficulties with facial affect recognition, depending on the cut-off criterion used.
This is clearly an area that warrants attention, particularly examining techniques for the rehabilitation of these deficits.
在创伤性脑损伤（TBI）后，许多人在沟通和人际关系方面都面临着巨大的挑战。这些困难可能部分归因于情绪感知问题。越来越多的证据表明，TBI 后对面部情感的识别特别困难。然而，目前还没有人试图系统地估计这个问题的严重程度或其发生的频率。
本文提出了一项元分析，旨在检查 TBI 后面部情感识别困难的程度。由此，可以估计 TBI 人群中这些损伤的频率。从比较中度至重度 TBI 成年患者与匹配的健康对照组在静态面部情感识别测量上的差异的 13 项研究中计算了效应量。
这些研究共提供了 296 名 TBI 成年人和 296 名匹配对照者的数据。13 项研究的综合加权平均效应大小为-1.11，这表明 TBI 患者在面部情感识别测量上的平均表现比健康同龄人低 1.1 个标准差。根据 TBI 人群的标准差估计和可能的分布形状建模，估计在中度至重度 TBI 患者中，有 13%至 39%的人可能存在显著的面部情感识别困难，具体取决于所使用的截止标准。
这显然是一个值得关注的领域，特别是研究这些缺陷的康复技术。
