The inventory
consists of 80 items, 16 items for each dimension. Respondents
answer on a three-level scale (I agree; I do not know; I disagree).
In this study only the dimensions of dominance (a = 0.721) and
extraversion (a = 0.752) were evaluated. Dominance is characterized
by imperiousness, self-assurance, independence, authoritativeness
and aggression. Extraversion is characterized by cooperation,
gregariousness, openness, sociability and communicability.
