Four samples, representing a broad age range, were compared in confirmatory factor analyses with respect to a four-factor model of aberrant driving behaviour. With the restrictions imposed on the data by the model, an approximate fit was obtained for all four samples. Additional analyses, which tested equality of factor loadings and correlations for different age groups, also indicated that the model was a good fit. Separate analyses on male and female respondents yielded similar results. Although earlier results have shown that aberrant driving behaviours are differentially related to age and gender, the findings suggest that structural differences in relation to age and gender may be of minor importance. The four-factor model of aberrant driving behaviour sufficiently meets statistical criteria in a model-generating phase. In addition, it is an appropriate solution to apply on data obtained from respondents varying in age and gender. (Author/publisher)
