JUAREZ ACOSTA, Fernando  and  MONTEJO HERNANDEZ, Maribel. Psychometric properties of the situation and aggressive behavior inventory and the motives for aggression inventory. Univ. Psychol. [online]. 2008, vol.7, n.1, pp. 149-171. ISSN 1657-9267.

Psychometric properties of the Situation and Aggressive Behavior Inventory and the Motives for Aggression Inventory were examined in a sample of 373 students of Medicine and Psychology in the city of Tunja in Colombia. In the Situation and Aggressive Behavior Inventory, most common aggressive behaviors were verbal aggression and attitudes or rage gestures, with physical aggression, verbal aggression and threatening showing the highest correlations; most common situation were study problems, family and interpersonal relations, and familiar or personal economy, no high correlations were found among situations or situations with behaviors. In the Motives for Aggression Inventory, most common motives were rage, emotional discomfort, self-defense and defending values. A Cronbach´s Alpha of 0.91 was obtained. Both of the questionnaires showed a single dimension (construct validity) and satisfactory divergent validity, with the Psychopathy subscale of the Clinical Analysis Questionnaire by Krug (1987), and convergent validity, with the Aggression Questionnaire by Buss and Perry (1992). Homogeneity coefficients were appropriated. Motives in the IMA, specially the pleasure of being aggressive, getting what you want, something makes you feel bad, and valuing aggressive persons, were predictors of the behaviors in the ISCA.
