Abstract
Research has shown that injury negatively impacts mood and self-efficacy. Research seems to suggest a possible discrepancy between the psychological recovery of mood and self-efficacy when compared to physical recovery (return to play). This study focused on the effects of a time-loss injury on mood and self-efficacy. The goal was to assess a possible discrepancy between physical -and psychological recovery. To test whether the ´ergodicity problem´ occurred, group results were compared to two individual players, to discern if the results were generalizable. Time-series data (single item self-reports) was collected daily from 29 elite male youth football (soccer) players, playing in their highest respective age division in the Netherlands across two seasons. The number of days until return to play were counted and then compared to the amount of days it took for the psychological variable to return to the pre-injury average. Almost every player dropped significantly in mood and self-efficacy during the complete injury process. Only two-third of the players dropped significantly in mood and self-efficacy on the first day of injury. The t-test for the group analysis was not significant p > 0.05 for both mood and self-efficacy. Even when adding a robustness measure the t-test remained insignificant. The individual players did drop significantly and showed longer psychological recovery than physical recovery, leading to a non-generalizable group result. Future research should do a second analysis where players without a drop on the first day are excluded. Keywords: Injury, Football, Nonergodicity, Psychological Recovery, Mood, Time-Series, Self-Efficacy.
