| dc.description.abstract | Road safety communication campaigns are considered an efficient strategy for reaching a wide audience. They aim at reducing the number and severity of road crashes by influencing road user behavior. Despite the large number of campaigns that have been designed and implemented in recent years, few have been formally evaluated. This paper presents the evaluation design and the implementation of a national road safety communication campaign on the effects of fatigue on driving behavior. The campaign targeted primarily professional drivers and, secondarily, all other drivers The definition of the objectives of the campaign was addressed through the health belief model. Objectives included increasing awareness of the severity of driving while fatigued and of effective countermeasures. The measurement variables of the evaluation design, also addressed by the health belief model, were knowledge, behavioral beliefs, risk comprehension, behavioral intentions, past behavior, and self-reported behavior. The evaluation was based on a nonexperimental design. The use of control groups was not feasible, since the whole population was exposed to the campaign and data were collected by means of a face-to-face questionnaire survey conducted before, during, and after campaign implementation. Process and outcome evaluations were conducted to assess the impact of the campaign on driving behavior. Results indicated that the audience was reached at a mean rate of 13%, and the distribution of campaign leaflets was the most effective media channel (70%). In addition, a statistically significant increase in the proportion of respondents who were aware of the causes and effects of fatigue while driving was observed. Similar results were indicated in testing behavioral beliefs, risk comprehension, behavioral intentions, and past behavior. The main message of the campaign reached both the primary and the secondary target groups, and its success can be seen by the increase in the percentage of professional drivers and all other drivers who self-reported that they stop and rest for 15 min in the "during" and "after" phases, as compared with the "before" phase. | en |
