Resumo(s)
Este estudo visa validar a versão portuguesa revista do Inventário Breve de Marcadores dos
Cinco Grandes Fatores de Personalidade (Big Five Mini-Markers Inventory), uma medida breve
da personalidade baseada no modelo dos cinco grandes fatores e na abordagem lexical proposta
por Saucier (1994). Com base numa amostra de 324 estudantes do ensino superior e através de
uma metodologia quantitativa, i.e., por inquérito transversal, analisaram-se as propriedades
psicométricas do instrumento, nomeadamente a sua estrutura fatorial, a consistência interna das
respetivas subescalas e a sua validade preditiva. Os resultados evidenciaram a replicação da
estrutura de cinco fatores, tal como esperado, com subescalas ortogonais e níveis elevados de
fiabilidade, apesar da reduzida extensão do instrumento (administração média de 5 minutos).
Em termos de validade em relação ao critério, a Conscienciosidade revelou-se o único preditor
de personalidade válido para a predição do rendimento académico (GPA), com efeitos
comparáveis aos reportados nos estudos de meta-análise mais recentes. Relativamente ao bem-estar subjetivo, verificou-se que os fatores de Neuroticismo, Conscienciosidade e Extroversão
contribuíram de forma válida e não redundante para a predição da satisfação com a vida, do
afeto positivo e do afeto negativo. Estes resultados sustentam a validade de construto e a
fiabilidade da versão portuguesa revista deste instrumento, suportando a sua utilidade enquanto
medida breve, e psicometricamente robusta da personalidade no contexto académico português,
com relevância para a investigação e prática psicoeducativa a este nível.
This study aims to validate the revised Portuguese version of the Big Five Mini-Markers Inventory, a brief personality measure based on the five-factor model and the lexical approach proposed by Saucier (1994). Based on a sample of 324 higher education students and using a quantitative methodology, i.e., a cross-sectional survey, the psychometric properties of the instrument were analyzed, namely its factor structure, the internal consistency of its subscales, and its predictive validity. The results showed the replication of the five-factor structure, as expected, with orthogonal subscales and high levels of reliability, despite the short length of the instrument (average administration time of 5 minutes). In terms of criterion validity, Conscientiousness proved to be the only valid personality predictor for academic performance (GPA), with effects comparable to those reported in the most recent meta-analysis studies. Regarding subjective well-being, it was found that the factors of Neuroticism, Conscientiousness, and Extraversion contributed validly and non-redundantly to the prediction of life satisfaction, positive affect, and negative affect. These results support the construct validity and reliability of the revised Portuguese version of this instrument, supporting its usefulness as a brief and psychometrically robust measure of personality in the Portuguese academic context, with relevance for psychoeducational research and practice at this level.
