Summary

This study investigates the relative efficacy of positively versus negatively valenced road safety campaign messages in improving dangerous driving attitudes. While road safety campaigns have traditionally relied on negative messages depicting adverse consequences, there is limited research on positive messages highlighting favorable outcomes, particularly regarding how drivers’ underlying motivations influence message impact. The authors aimed to determine which message valence yields greater message acceptance, lower rejection, and higher response efficacy, while also examining whether specific motivators for dangerous driving predict these outcomes. The researchers employed a between-subjects experimental design with 160 licensed drivers (120 female, 30 male, 10 other). Participants completed an online survey assessing demographics, current dangerous driving behaviors using the Manchester Driving Behaviour Questionnaire (DBQ), and motivations for dangerous driving using the Motives for Dangerous Driving Scale (MDDS), which measures driving fast/risk-taking, confidence in driving skills, and disrespect for traffic laws. Participants were randomly assigned to view either a positive video message emphasizing the benefits of safe driving or a negative video depicting the physical consequences of speeding. Following exposure, participants rated message acceptance, message rejection, and response efficacy, and reported their planned future driving behaviors. Results indicated that the positive campaign was significantly more effective overall than the negative campaign. Participants in the positive condition reported significantly greater response efficacy and message acceptance, along with significantly lower message rejection. Analysis of demographic differences revealed that age and sex influenced message impact; for instance, younger male drivers showed greater acceptance of the positive message, while older female drivers were more accepting and less rejecting of it. Furthermore, among female drivers, specific motivators predicted message impact: higher confidence in driving skills was significantly associated with greater response efficacy for the positive message. Regarding behavioral change, participants across all groups reported intending to drive less dangerously after viewing the messages, with female drivers showing a significant reduction in planned dangerous behaviors compared to males. The findings suggest that positively valenced road safety campaigns may be more effective than traditional negative approaches in generating message acceptance and reducing rejection. The study highlights the importance of targeting campaigns based on demographic factors and psychological motivators, such as driving confidence, to enhance efficacy. These results support a shift toward more personalized and targeted road safety messaging strategies that leverage individual differences to improve driver attitudes and behaviors.
