Reliability of the Sport Concussion Assessment Tool 5 baseline testing: A 2-week test–retest study

To examine short-term test-retest reliability of the Sport Concussion Assessment Tool 5 (SCAT5). Longitudinal study. Sixty-two professional male ice hockey players (mean age=22.5, SD=3.2) completed a preseason baseline test twice over a two-week interval. Half of the players were tested by the same assessor on both testing sessions. Spearman’s correlations (rs) were used to determine linear agreements, and Wilcoxon signed rank tests (sig r) were used to determine mean differences, between testing sessions. Symptoms had high test–retest reliability (Score: rs=0.85, p
