El ajuste de los items se valoro mediante medias cuadraticas de Outfit e Infit con valor esperado entre 0.50 y 1.50, considerado productivo para la medicion, y mediante correlaciones item-medida con valor esperado positivo y mayor a .30 (Bond & Fox, 2015).
Test items with MnSq infit and outfit values falling outside 0.6-1.4 were considered as all-fitting.
Following the criteria proposed by Bond and Fox (2007), the results revealed that all items fit the Rasch model, except six items (Items 1A, 10A, 3B, 5B, 6B and 11B) which have outfit and infit mean square (MNSQ) indices outside the acceptable range of 0.60-1.40.

Como as escalas avaliadas mensuravam apenas um constructo (inseguranca alimentar), elas foram analisadas segundo os valores de ajuste (Infit), sendo que todas que utilizaram este modelo para validacao apresentaram valores adequados (0,8 a 1,2) (31).
Los items tuvieron un ajuste optimo en Infit; su promedio en 1,0 indica ajuste perfecto entre datos y modelo (23); con relacion al Outfil, el ajuste fue menos bueno.
Table 4 shows that all items fit a single overall construct for the simplified/revised version (infit range 0.78-1.27; outfit range 0.70-1.25).
The mean square fits (IMNSQ and OMNSQ) and the z statistics (INFIT ZSTD and OUTFIT ZSTD) are closer to their expected values +1 and 0, respectively, for persons (students) and items (questions).
