Assessing construct validity of the Beighton Score as a measure of generalized joint hypermobility in varsity athletes.

Abstract: The Beighton Score (BS) is a tool that dichotomizes those who have generalized joint hypermobility (GJH) and those who do not. Unfortunately, the BS is often used in populations that it was not originally developed for, including athletes for screening purposes. The construct validity of the BS remains unknown in this population. This secondary analysis investigated the construct validity of the BS by comparing varsity athletes' passive shoulder and hip ranges of motion (ROMs) to their respective BS and individual forward bend tests (FBTs). There were statistically significant but weak correlations between shoulder ROMs and the BS (r=0.142, p=0.021). Mean hip ROMs were greater by 5-degrees in those with positive FBTs compared to those with negative FBTs. This difference falls within typical measurement errors that occur in practice. Therefore, our results do not support the construct validity of the BS as a measure of GJH in healthy athletes.
