Adequalidade e evidência psicométrica de uma escala de personalidade baseada no Big Five Inventory-10 a uma região no Sul do Brasil

Abstract

The Big Five theory has been the basis for much of the personality assessment work conducted recently. Currently this is the theory that provides a better understanding of personality. The Big Five inventory- 10 (BFI-10) is a scale composed of 10 items that assesses five dimensions of personality, with two items for each factor: Extroversion, Agreeableness, Conscientiousness, Neuroticism and Openness. The purpose of this study due to the need for a brief instrument based on Big Five Theory for use in research in Brazil. Were interviewed 1158 people, being the majority female (58%) aged between 14 and 35 years. In the original form of the instrument was added one item in each factor to select later the 10 items with better psychometric qualities. There was evidence of construct validity and the rates of internal consistence were acceptable. At the end of the analysis it was identified that Neuroticism was the factor that demonstrated greater legitimacy, whereas Agreeableness was the less representative. Associations were observed among factors and the sociodemographic variables: gender, age and scholarity. It has been concluded that the adapted BFI-10 can be used when the time available is very limited. Considering the limitations of a so brief scale, the results should be interpreted cautiously. Further studies should be made to complement the psychometric characteristics of the scale
