A meta-analysis conducted by Binder, Rohling and Larrabee established a relationship between mild traumatic brain injury (TBI) and small reductions in cognitive functioning in individuals assessed more than 3 months post-injury. As a follow-up, this study summarized similar research that (1) was published since the previous meta-analysis, and (2) included data collected at any stage post-injury. An extensive literature search revealed 17 suitable studies from which effect sizes were aggregated. The overall effect size was g = 0.32, p < .001. Speed of processing measures had the largest effect, g = 0.47, p < .001. The merging of post-acute effect sizes with those reported in Binder et al.'s review yielded a nonsignificant result, g = 0.11. Time since injury was found to be a significant moderator variable, with effect sizes tending to zero with increasing time post injury.
Binder、Rohling和Larrabee进行的一项荟萃分析确定了轻度创伤性脑损伤（TBI）与受伤后3个月以上接受评估的个体认知功能的小幅下降之间的关系。作为后续研究，本研究总结了类似的研究，这些研究（1）自上次荟萃分析以来发表，（2）包括在受伤后任何阶段收集的数据。广泛的文献检索发现了17项合适的研究，并对效应量进行了汇总。总体效应量为g = 0.32，p < .001。处理速度测量的效应最大，g = 0.47，p < .001。急性后期效应量与Binder等人综述中报告的效应量合并后，结果不显著，g = 0.11。发现受伤后的时间是一个显著的调节变量，随着受伤后时间的增加，效应量趋于零。
