The Role of Affect in Predicting Social Behaviors: The Case of Road Traffic Violations

Increasing support for the relationship between road traffic violations and accident liability has led to research focusing on the motivational factors that promote these behaviors. In Study 1, a large sample of young (17–40 years) drivers were asked to complete the Driver Behavior Questionnaire (DBQ; Parker, Reason, Manstead, & Stradling, 1995). Factor analysis revealed 3 factors: errors, highway code violations, and more interpersonally aggressive violations. In Study 2, a smaller sample of drivers was recruited (17–70 years) to investigate further this distinction between different types of violation and also the role of affect in predicting behavior. Factor analysis of a modified DBQ revealed 3 types of violation. Measures of positive affect were found to be good predictors of all 3 violation types. Discussion focuses on social psychological and applied implications.
