Percepções de justiça: estudos de dimensionalização com professores do ensino superior

This paper aims at showing how an instrument for measuring justice perceptions of university teachers was developed and validated. Four stages were accomplished: a) the items were collected; b) the questionnaire was developed; c) an exploratory factor analysis was applied to the data collected from a sample of university teachers; d) confirmatory factor analysis was applied to the data of another sample. The findings are as follow: a) teachers distinguish five justice dimensions (rewards distribution, work distribution, procedural, interpersonal and informational); b) in comparison with the four-factor model (in which interpersonal and informational descriptors are aggregated in the same factor), this five-factor model fits better the data; c) moreover, it brings higher predictive power to teachers' affective commitment. The research contributes to understand the dimensions of justice perceptions in different contexts, and provides a measurement tool with good psychometric properties.
