Is Going Beyond Rasch Analysis Necessary to Assess the Construct Validity of a Motor Function Scale?
Guillot T, Roche S, Rippert P, Hamroun D, Iwaz J, Ecochard R, Vuillerot C; the MFM Study Group.
Arch Phys Med Rehabil. 2018. 99(9), 1776-1782.e9.
Comparison of the fit quality of the confirmatory factor analysis (CFA) and the Rasch models on MFM item scores in Charcot-Marie-Tooth disease, Facio-Scapulo-Humeral Dystrophy (FSHD) and Steinert’s disease (DM1).
The CFA model showed a better fit to the data than the Rasch model, regardless of the disease (P <0.001).
