Samenvatting
It is shown that Fishbein's 'theory of reasoned action' can be used to explain people's intentions to wear seat belts. As Bentler and Speckart (1979) have proposed, a self-report measure of past behavior is shown to significantly improve the model's power; this extented Fishbein model being capable of accounting for the majority of the effects that extraneous variables, which are known to inlfuence seat-belt use, have upon a person's behavioural intentions. In addition, it is shown that the model's motivation to comply term is, as Ajzen and Fishbein (1980) have proposed, a uni-polar rather than a bi-polar construct, but that even when this construct is scored as uni-polar, it does not signifantly add to the model's predictive power.
