Position of aggressiveness in common latent space of PEN model and model Big Five Plus Two

The purpose of this research was to examine the relations between different aspects of aggressiveness and personality traits. Buss-Perry Aggression Questionnaire (AQ), Eysenck Personality Questionnaire (EPQ), which represent psychobiological model, and inventory Big Five Plus Two Inventory (BF+2), which represent psycholexical model of personality in Serbian language, were administered to 478 participants. The results revealed that affective impulsive aggressiveness and predatory or instrumental aggressiveness could be identified in the aggressiveness - personality traits relationships. Those aspects of aggressiveness could take manifest or latent character. As expected, Psychoticism from EPQ, Aggressiveness, and Negative Valence from BF+2 showed a significant contribution to all identified forms, except for Aggressiveness in relations with “acting out” physical aggression. Although these personality traits carry out significant loadings, these loadings were not always the highest. Affective-impulsive aggressiveness, which was mainly determined by the components of latent domain AQ, was related to Neuroticism from both models. The remaining forms of manifest aggressiveness were related to low Consciousness, whereas Physical aggression is connected to Extraversion and Oppennes. This connection represents possible “acting out” reaction or more frequent tendency of impulsive physical aggression. The results showed that aggressiveness represents a multidimensional construct which could be explained by specific constellation of personality traits, depending which aspects of aggressivenes are of interest.
