Differences in Change Scores and the Predictive Validity of Three Commonly Used Measures Following Concussion in the Middle School and High School Aged Population

Reviews
The article titled, “Differences in Change Scores and the Predictive Validity of Three Commonly Used Measures Following Concussion in the Middle School and High School Aged Population, by M. Barlow et al, 2011, is a level B study that utilizes a cohort comparison design. The title, abstract, and background information are generally effective in providing appropriate information and understanding. However, the study has a number of methodological concerns related to the sample characteristics, assessment tools, and statistical procedures that were used. The limitations of this study are serious enough to call into question the results and proposed implications.
