Kwestionariuszowy pomiar pięciu cech osobowości dzieci i dorastających. Polska adaptacja Big Five Questionnaire-Children (BFQ-C)

The article presents the psychometric properties of the Polish version of the Big Five Questionnaire – Children (BFQ-C; Barbaranelli, Caprara, Rabasca & Pastorelli, 2003). BFQ-C is a questionnaire measuring five personality traits (energy/extraversion, agreeableness, conscientiousness, emotional instability and intellect/openness) in late childhood and adolescence. Two versions of BFQ-C were used in the study: in the first one children and adolescents describe themselves, and in the second one other informants (parents and teachers) provide information about children and adolescents. The participants in the study were 1,241 children and adolescents (aged from 7 to 15 years), 226 parents, and 475 teachers. The reliability was assessed by Cronbach’s alpha. The structural validity was assessed in a set of factor analyses. Convergent and discriminant validity were assessed using a multitrait–multimethod matrix (five traits and two versions of BFQ--C) and analyzed in structural equation modeling. The external validity was assessed by inspecting the relations between the personality traits measured by BFQ-C and temperamental traits in the model proposed by Oakland, Glutting, and Horton (1996), as well as temperamental traits in the model by Buss and Plomin (Oniszczenko, 1997). Both reliability and all kinds of validity were at acceptable levels, which leads to the conclusion that BFQ-C can be used in scientific research
