Gnacinski, SL, Cornell, DJ, Meyer, BB, Arvinen-Barrow, M, and Earl-Boehm, JE. Functional Movement Screen factorial validity and measurement invariance across sex among collegiate student-athletes. J Strength Cond Res 30(12): 3388-3395, 2016-The Functional Movement Screen (FMS) is a screening tool used to evaluate functional movement quality and subsequent musculoskeletal injury risk. Despite recent research on the factorial validity of the FMS, no confirmatory factor analysis (CFA) has been conducted to examine measurement invariance across sex among student-athletes. The primary purpose of the current study was to confirm the factor structure of the FMS measurement model in a collegiate student-athlete population. It was hypothesized that the 1-factor model would demonstrate better model fit than the recently proposed 2-factor model. The secondary purpose of the study was to examine FMS measurement invariance across sex using the previously identified measurement model. It was hypothesized that FMS measurement invariance would hold across sex. Male (n = 88) and female (n = 88) collegiate student-athletes completed FMS screening during the off-season. Factorial validity was examined using CFA procedures, and model parameters were estimated using maximum likelihood estimation. Measurement invariance was examined by comparison of fit indices between hierarchically constrained models. Results revealed support for both the 1- and the 2-factor models; however, the 2-factor model failed to fit the data significantly better than the 1-factor model. Results also indicated that measurement invariance did not hold across sex, indicating that the FMS sum score construct is not measured equivalently in male and female populations. Collectively, results provide evidence for the use of the unidimensional FMS sum score among collegiate student-athletes, yet prompt caution because it relates to the evaluation of sex differences in sum or movement pattern scores.
