SEAT BELTS: THE IMPORTANCE OF SITUATIONAL FACTORS

To investigate the relative importance of situational and individual factors, respectively, for seat belt use in private cars, two studies were conducted. In the first study, 75 car owners, drawn from the car register in Uppsala answered a questionnaire including items concerning their belt usage in various situations. The major situational difference was found to be between city and highway situations with only small variations within each environment. Point estimates of variance showed that the major proportion of the reported behavior variation was due to individual variation. A coefficient of internal consistency approaching unity indicated unidimensionality of the variables. A hypothetical model was presented that accounted for the results in terms of two latent variables: (a) disposition for belt use, and (b) difficulty of situation. The second study was carried out to get some indication of the validity of the verbal reports. Observations of belt use were carried out on 13 mornings during a three month period, and 105 of those who had passed regularly were later on identified and answered a questionnaire, including some of the items of the first study. The results of the cross-validation supported the model. The correspondance between reported and observed belt use was relatively high, r = .73 in this non-random sample, and despite a tendency to overestimate usage, it was concluded that verbal reports could be used as indicators of seat belt use.
