This study aims to determine how these variables determine the prevalence of prosocial and aggressive behaviors in Mexican drivers. Afirst sample of 444 drivers in the city of Cuernavaca, in the state of Morelos, in the central region of Mexico was examined. It was found that the relationship between Hope and Self-Efficacy is incredibly strong, and that they are both, as a system, predictors of Prosocial Behavior. However, Aggressive Behavior was found to negatively predict all three of the other variables, but in a weak manner. A second sample of 316 individuals confirmed these findings, and also determined that the manner in which a person behaves determines his or her negative emotions.
