• Abstract:
  Eco-driving consists of using energy-efficient approaches to driving aimed at reducing ; fuel consumption and, ultimately, CO2 emissions. A previous study found that an EcoDrive ; informational campaign was effective at increasing the use of eco-driving behaviors, but only ; when employees perceived that their supervisor supported the program and when they were ; personally motivated to perform the eco-driving behaviors. In order to build upon the findings of ; our previous study, the present study focused on increasing the use of eco-driving behaviors ; through an informational eco-driving campaign combined with supervisor training to support the ; use of eco-driving practices. ; In this study we collected baseline measures of driving knowledge, attitudes, and ; behaviors from employees at three organizations, as well as follow-up data collected at two ; months (Time 2) and six months post-intervention (Time 3). Implementing a quasi-experimental ; design with a control group (informational campaign only) and an experimental group ; (informational campaign combined with supervisor training), we tested the incremental ; effectiveness of supervisor training compared to the effect of an informational campaign alone. ; In total, 19 supervisors received supervisor training (supervisor training group) and 10 ; supervisors were provided with the informational campaign materials only (control group). We ; collected data from 144 unique participants across the three time points, and of these responses ; we were able to match responses for 50 participants from Time 1 to Time 2 and 48 from Time 1 ; to Time 3. We were also able to match responses from 38 participants across all three time ; points; however, because our interest was in change from baseline, and in order to increase our ; statistical power, analyses were conducted comparing Time 1 to Time 2 and Time 1 to Time 3 ; data. We assessed changes in self-reported knowledge, attitudes, and behaviors using mixedmethod ; ANOVAs to assess the within-person change across time points and compare the ; effectiveness of the intervention between the control and supervisor training groups. ; We found that, in general, participants reported using eco-driving behaviors more often in ; the follow-up surveys compared to baseline measures. However, we did not find direct support ; for the supervisor training intervention providing an incremental increase in eco-driving ; behaviors and attitudes compared to the informational campaign alone. On the other hand, we ; did find that supervisor support, frequency of communication about eco-driving, and the ; percentage of employees who viewed the EcoDrive materials were greater in the supervisor ; training group compared to the control group. Additionally, employees in the supervisor training ; group rated the EcoDrive materials as more useful compared to the control group. ; Based on these findings, the supervisor training seemed to be effective in improving ; indicators of supervisor support; however, it may be that our limited sample size did not allow us ; to find statistically significant differences between the two groups in eco-driving behaviors. In ; this report we discuss in more detail the basis for this study, the implementation of the ; intervention, the results, and potential explanations for our findings in order to inform future ; studies. We also provide a detailed account of the methodology used in this study.
