The aim of this study was to compare the original version of Escala de Competência de Estudo – ECE (C&T), with the reduced one by using the Item Response Theory. A sample of 126 college students, male and female, between 17 and 48 years old (M = 24.65, SD = 6.54) answered the test. The precision coefficients obtained were .91 for the original scale and .90 for the reduced one, indicating a good level of precision for both. The scale’s adjustment to the Rasch Model was analyzed, resulting an average error of 0.11 (SD = 0.02). The scale with 54 items presents an item’s infit mean of 1.00 (SD = .18), and the reduced scale presents an item’s infit mean of 1.01 (SD = .20), and the outfit’s mean value is 1,02 (SD = 0.41). The difficulty of the items was similar in the two scales. The results presented a better adjustment for the reduced scale, seeing that there were less misfit items, in terms of quantity and value. |
