NUNES, Carlos Henrique Sancineto da Silva  and  HUTZ, Claudio Simon. Development and validation of an Agreeableness scale in the Big Five personality model. Psicol. Reflex. Crit. [online]. 2007, vol.20, n.1, pp.20-25. ISSN 0102-7972.

The present study was designed to develop and assess construct validity of an Agreeableness scale (Escala Fatorial de Socialização - EFS) in the Big Five model. In this model, Agreeableness is comprised by traits that describe altruism, straightforwardness, trust in people, as well as coldness, antisocial behaviors, among others. The participants were 1.100 individuals, from five States in Brazil, of both sexes, with high school or university level of education. Factor analyses were conducted to determine the EFS dimensions. A 3-factor solution was found to be more adequate. The factors found were named: Cordiality, Pro-sociability, and Trust in people. Internal consistency (Cronbach's alphas) for the factors were .91, .84, and .80 respectively, and .92 for the general scale.
