Do beliefs differ between frequent and infrequent hand-held and hands-free phone users while driving? A Polish study

Aim Although it is currently legal in Poland to use a hands-free mobile phone while driving, research suggests that it is not significantly safer than using a hand-held mobile phone. The present study used the theory of planned behaviour (TPB) to examine the relationships that three types of beliefs (behavioural, normative and control beliefs) have with the frequency of drivers' hands-free and hand-held mobile phone use. Subjects and methods The sample comprised 298 Polish drivers (35% females) aged between 18 and 40 years old (mean age: 21.05 years, standard deviation = 2.38). Results Two multivariate analyses of variance (MANOVAs) were conducted to investigate the differences between the two groups (hand-held and hands-free) of frequent and infrequent mobile phone users, with regard to their behavioural, normative and control beliefs. Significant differences were found in all of the control beliefs for both hand-held and hands-free mobile phone users. Similar normative differences were identified for both hands-free and hand-held mobile phone use, but while three behavioural beliefs differed significantly for hands-free use, no behavioural beliefs were significant for hand-held mobile phone use. Finally, composite measures of the behavioural and control beliefs were predictive of being a frequent hand-held mobile phone user, but none of the three beliefs were predictive of being a frequent hands-free user. Conclusions These results demonstrate potential directions for behavioural change aimed at reducing or preventing the use of mobile phones while driving.
