The purpose of this study was to verify goodness-of-fit by Many-Facets Rasch model for
applying martial arts training satisfaction scale to security martial arts trainees. To achieve
the purpose, 255 security martial arts trainees’ data were used in the analysis. In addition,
In addition, the AMOS 20.0 program was used for unidimensionality validation, and take
advantage of the Facets 3.61 program for goodness-of-fit verification. Specific results are as
follows: First, Unidimensionali test results showed that model fit, reliability and standardized
β value are suitable. Second, the analysis results of goodness-of-fit, items 1, 2, 3 are
inadequate, 4, 8, 11, 13, 14 items once found to be over-fit questions. Also, analysis of item
difficulty, item 1 has highest difficulty and item 7 was lowest. Third, According Facets item
difficulty and response difference verification result, female group exhibited a high level of
item difficulty compared to the male group, goodness-of-fit was all accurate. As the result
of item difficulty and response difference verification based on Martial arts training flow,
there is no response difference according to the training experience. On the other hands,
less than 4 years to 5 years and less than 5 years to 6 years trainees represented over-fit
features. Results of item difficulty and response difference verification by grade level, first
grade was the most highly recognized the item difficulty and fourth grade was also
recognized the lowest of item difficulty Fourth, the response category analysis showed that
the six points response categories are not appreciate.
