Abstract: A Belgian national safety belt campaign was evaluated by means of a questionnaire survey in a student sample. The evaluation was done through a three group after-only design with the use of one control group and two experimental groups. The first experimental group, the attentive group, was exposed to the campaign material in a very direct, attentive way, whereas the second experimental group, the pre-attentive group, was exposed rather inattentively. The framework of the Theory of Planned Behavior (TPB) was extended with a habit and a past behavior variable in order to verify whether seat belt usage is to be understood as habitual, repeated or planned behavior. In terms of campaign effect, the comparison of the pre-attentive group and the control group revealed no significant differences. However, the attentive group and the control group differed significantly regarding perceived behavioral control (confidence), perceived behavioral control (motivation), habit, past behavior, behavioral intention and behavior. In terms of explaining seat belt usage, linear regression models were fitted and gave most support for the repeated behavior hypothesis. According to the latter, using seat belts is recycling an originally reasoned behavior, yet without systematically going through the whole underlying reasoning every time a situation in which the decision to wear a seat belt (or not) presents itself. The practical implications of these findings are discussed more in detail.
