The current study examines driving behaviour of youth as a function of desirability, controllability and verifiability of this behaviour, in relation to locus of control. The author expected that the occurrence of undesirable behaviour would increase when this behaviour was not visible to others, or could be ascribed to external circumstances. These mechanisms were expected to operate for externally oriented subjects, but less so for internally oriented subjects. A questionnaire was administered to 120 Dutch university students regarding their driving behaviour. The questionnaire described two scenarios in which desirability, verifiability, and controllability of behaviour were systematically manipulated. The primary dependent variable involved judgements on the likelihood that one would engage in a particular behaviour. The data were analysed using ANCOVA. The results supported the expectation that verifiability of behaviour would be more important for externally than for internally oriented subjects. For controllability of behaviour, no such effects were found. Implications and limitations are discussed. (A)
