Big Five Inventory-2-Short: evidências de validade e confiabilidade na segurança pública

Abstract

The present study aimed to gather evidence of construct validity, based on the internal structure, of the Big Five Inventory-2-Short (BFI-2-S) for the context of Brazilian public security. 10.885 public security agents from different police forces from all federal units in Brazil were recruited through an electronic questionnaire, most were male, 80.1% (ƒ = 8,156), aged between 18 and 73 years (M = 41.55; SD = 8.02), working in the organization between 1 and 45 years (M = 14.51; SD = 8.46). Agents completed the BFI-2-S personality test and a sociodemographic questionnaire. The responses obtained were split into two random subsamples and a cross-validation procedure was performed. Thus, in both subsamples Exploratory Factor Analysis was carried out, which indicated a structure composed of three factors, with adequate reliability. Despite differing from the model theoretically proposed by the instrument, the BFI-2-S proved to be an adequate instrument for assessing the dimensions of conscientiousness, emotional instability and extroversion in Brazilian police officers.
