Review by Matt Holcomb, PhD
The present article is based on the combination of the data derived from 3 case-controlled studies which used the Concussion Symptom Inventory (CSI). The aim was to identify which inventory items were more relevant in detecting and tracking sport-related concussions. As the authors point out, the literature on concussions is filled with empirically derived controlled outcome studies, which has led to confusion on best practices in classifying concussions and determining return-to-play. This study resulted in an empirically derived CSI. Twelve items were found to adequately discriminate concussed from non-concussed, resulting in a much more brief inventory (from 20-27 items). This study is an important step in formalizing standards and practices for evaluating concussions. As with most scale development the study lacks independent verification, and further development of cut-off scores which could aid the process of concussion identification. Read more
