To determine the stability of the Sport Concussion Assessment Tool (SCAT) 5 between consecutive seasons in uninjured collision and combative varsity athletes.
Thirty-six athletes (19 females) were recruited to participate (wrestling [n = 12], rugby [n = 14], and hockey [n = 10]). The SCAT5 was administration at the start of the 2017 and 2018 seasons. Median baseline demographics for 2017 were as follows: age (19 years [range: 17-24 years]), height (174 cm [range: 149-195 cm]), and weight (76 kg [range: 57-118 kg]). Outcome metrics included subcomponents of the SCAT5: symptom reporting, standardized assessment of concussion (SAC), neurological screening, and balance performance measured with the modified balance error scoring system (mBESS). Wilcoxon signed-rank tests and Cronbach's alpha (α) values were calculated to determine the stability between consecutive years for the SCAT5 variables in the same cohort of athletes. Bonferroni corrections were applied for Wilcoxon signed-rank tests, where alpha = (0.05/9).
Between the 2017 and 2018 seasons, no differences were noted in symptom reporting (), SAC (), neurological screening (), and balance performance on the mBESS (). The Cronbach's alpha displayed unacceptable to questionable levels of within-subject stability (range: α = 0.34-0.70) for all subcomponents, except months in reverse order (α = 0.92).
While no statistical differences were present for all SCAT5 subcomponent metrics between 2017 and 2018 baselines, all but one displayed unacceptable to questionable stability (α ≤ 0.70) when retested one year later. Further research is needed to understand the appropriate time duration baseline SCAT5 values can reliably be utilized within longitudinal studies; as well as the normal variation of SCAT5 reporting/scoring.
确定未受伤的碰撞和格斗校队运动员在连续赛季中 Sport Concussion Assessment Tool (SCAT) 5 的稳定性。
招募了 36 名运动员（19 名女性）参与研究（摔跤[n=12]、橄榄球[n=14]和曲棍球[n=10]）。在 2017 年和 2018 赛季开始时，对运动员进行 SCAT5 评估。2017 年的中位数基线人口统计学数据如下：年龄（19 岁[范围：17-24 岁]）、身高（174 厘米[范围：149-195 厘米]）和体重（76 公斤[范围：57-118 公斤]）。结果指标包括 SCAT5 的子成分：症状报告、标准化脑震荡评估（SAC）、神经学筛查以及改良平衡错误评分系统（mBESS）测量的平衡表现。Wilcoxon 符号秩检验和 Cronbach's alpha（α）值用于确定同一批运动员连续两年的 SCAT5 变量的稳定性。Wilcoxon 符号秩检验应用了 Bonferroni 校正，其中α=（0.05/9）。
在 2017 年和 2018 赛季之间，症状报告（）、SAC（）、神经学筛查（）和 mBESS 上的平衡表现（）无差异。除了相反月份（α=0.92）外，所有子成分的 Cronbach's alpha 显示出不可接受到可疑的个体内稳定性（范围：α=0.34-0.70）。
虽然在 2017 年和 2018 年基线之间，所有 SCAT5 子成分的度量都没有统计学差异，但在一年后重新测试时，除了一个子成分外，所有子成分的稳定性都不可接受到可疑（α≤0.70）。需要进一步的研究来了解在纵向研究中可以可靠地使用 SCAT5 基线值的适当时间间隔；以及 SCAT5 报告/评分的正常变化。
