Abstract
After the construction of an instrument, its continuous improvement becomes necessary. In this context, it is relevant to know whether the factor structure of a test is maintained in other samples. Hence, the aim of this study was to search for validity evidence based on internal structure for the Aggression Tendency Assessment Scale - EATA. 480 university students of courses in the areas of Human Sciences (41,2 %), Biological Sciences (41,2 %) and Exact Sciences (17,5 %), of a university in the south of Minas Gerais, Brazil, were studied. The participants age ranged from 18 to 55 years, with an average of 24 years (SD = 6.31). It was performed a confirmatory factor analysis, using the method of estimation maximum likelihood, showing that the tested model was not appropriate for the set of observed data. The exploratory factor analysis resulted in a scale with 32 items, subscale A with 18 items (Cronbach’s alpha = 0.83), subscale B with 6 items (Cronbach’s alpha = 0.75) and subscale C with 7 items (Cronbach’s alpha = 0.63). The original structure was not confirmed in none of the analyses and a new internal structure is proposed.
