Abstract

ABSTRACTObjective: Self-report measures are typically used to assess the effectiveness of road safety advertisements. However, psychophysiological measures of persuasive processing (i.e., skin conductance response [SCR]) and objective driving measures of persuasive outcomes (i.e., in-vehicle Global Positioning System [GPS] devices) may provide further insights into the effectiveness of these advertisements. This study aimed to explore the persuasive processing and outcomes of 2 anti-speeding advertisements by incorporating both self-report and objective measures of speeding behavior. In addition, this study aimed to compare the findings derived from these different measurement approaches.Methods: Young drivers (N = 20, M age = 21.01 years) viewed either a positive or negative emotion–based anti-speeding television advertisement. While viewing the advertisement, SCR activity was measured to assess ad-evoked arousal responses. The RoadScout GPS device was then installed in participants' vehicles for 1 week to measure on-road speed-related driving behavior. Self-report measures assessed persuasive processing (emotional and arousal responses) and actual driving behavior.Results: There was general correspondence between the self-report measures of arousal and the SCR and between the self-report measure of actual driving behavior and the objective driving data (as assessed via the GPS devices).Conclusions: This study provides insights into how psychophysiological and GPS devices could be used as objective measures in conjunction with self-report measures to further understand the persuasive processes and outcomes of emotion-based anti-speeding advertisements.

Highlights

  • Young drivers aged 17 to 25 years constitute a high risk road user group

  • The findings revealed that there was general concordance between the self-report and objective measures of arousal and between the self-report and objective measure of driving behaviour

  • The current findings showed general concordance between the self-report and objective measure of arousal, with such arousal assessed as a measure of persuasive processing

Summary

Introduction

Young drivers aged 17 to 25 years constitute a high risk road user group. Overall, they are more likely to engage in risk taking behaviours such as speeding and of being involved in road trauma. To further examine if the self-reported and objective measures of driving behaviour differed as a function of advertisement condition (positive versus negative), Fisher’s z transformation was conducted on the above-mentioned correlation coefficients.
