%X OBJECTIVE: To assess the concurrent validity and test re-test reliability of the Michigan Traumatic Brain Injury Identication Method (MTBIIM). The psychometric  properties of this concussion index were investigated by comparing the agreement  between player self-reported diagnosed concussions and medical record diagnosed  concussions among professional rugby union players. Study Design: Cross-sectional  study i) validation and ii) test re-test reliability. <br><br>METHODS: The MTBIIM was  administered via a structured interview to obtain the number and nature of player  self-reported concussion histories from players, while contracted to the host club. Self-reported concussion history information was compared to medically recorded data  captured between 2008 and 2017. A mixed-ects logistic regression model explored  predictors of player self-report accuracy. <br><br>RESULTS: Data from 62 players  (25.39[4.36] years) included 99 unique rugby related concussions. Medically  documented concussions (n = 92) per player (1.48 [1.96]) were 30% more than the mean  number of self-reported diagnosed (n = 63) concussions per player (1.02 [1.21]  events). Overall, self-reported diagnosed concussions and medical record diagnosed  concussion histories had a 'fair' level of agreement (k=0.274; SE [0.076]), p=.001). Self-reported lifetime concussion history was signicantly negatively correlated with  recall of concussions. <br><br>CONCLUSIONS: Initial concurrent validity of the MTBIIM was  found to be fair with the average athlete under-reporting the number of clinically  diagnosed concussions.<p /> <p>Language: en</p>
