Multifaceted concussion assessment battery: sensitivity at the expense of specificity?

Objectives: A multifaceted assessment battery is recommended for testing suspected concussed athletes; however, the individual tests have limitations and potentially may lead to false positive outcomes. Therefore, the purpose of this study was to psychometrically evaluate concussion assessment tools used for intercollegiate student-athletes, with a focus on the time interval between baseline and subsequent assessments.

Methods: Ninety-two collegiate student-athletes matched between concussion ( = 46.

Statistical Inference for Box-Cox based Receiver Operating Characteristic Curves.

Receiver operating characteristic (ROC) curve analysis is widely used in evaluating the effectiveness of a diagnostic test/biomarker or classifier score. A parametric approach for statistical inference on ROC curves based on a Box-Cox transformation to normality has frequently been discussed in the literature. Many investigators have highlighted the difficulty of taking into account the variability of the estimated transformation parameter when carrying out such an analysis.

Athletic Identity and Sport Injury Processes and Outcomes in Young Athletes: A Supplemental Narrative Review.

: Identity formation, a primary developmental task of adolescence, may be particularly relevant to another commonly occurring event for young athletes-sport injury. Relationships between a subdimension of self-identity-athletic identity-and sport injury processes and outcomes have been documented in the general athlete population. The purpose of this supplemental narrative review is to explore the potential role of athletic identity in the risk of injury occurrence and responses to and consequences of injury among young athletes.
