Validación de un Inventario de Comportamientos Agresivos en el Tránsito

Abstract

Over 20000 people die due to car accidents (Cervantes-Trejo, 2009). Moreover, other 700000 suffer injuries that result in hospitalization, as well as 40000 individuals end up with some sort of disability (Cervantes-Trejo, 2009). Alarmingly, Cervantes-Trejo (2009) reported that this problematic is rising every year. Aggressive driving is one of the main causes of traffic accidents. In this study, aggressive driving is defined in terms of inconsiderateness towards others, risky driving and frustration/hostility behaviors. The aim of this study was to create and validate an instrument to assess the construct. We intended to answer the following research question: Is the Aggressive Driving Behavior Inventory valid and reliable? This is a local validation study in Cuernavaca, Morelos in Mexico. We carried out three studies sampling 2454 participants. In the first study, we found more items in the dimension frustration/hostility behaviors rather than the ones in the other dimensions. In the second one, we discovered a high construct validity and acceptable internal consistency of the instrument. In the third one, we found that the measure obtained a high construct validity and good internal consistency. Nonetheless, we didn’t assess the content, convergent and divergent validity. We concluded that the Aggressive Driving Behavior Inventory is valid measure but needs further assessment of its psychometric soundness in a representative sample.
