Social psychology of seat belt use: A comparison of theory of planned behavior and health belief model

Simsekoglu, Oezlem
Lajunen, Timo
Despite the proven effectiveness of seat belt use in reducing injury severity in road traffic accidents, a large number of car occupants do not use a seat belt in Turkey. The main aim of the present study was to explain self-reported scat belt use among front seat passengers with the basic and extended (habit, moral norm and anticipated regret added) theory of planned behavior (TPB) model and the health belief model (HBM), and to compare the models' predictive power and fit to the data. Students (N = 277) completed a questionnaire including demographic information and the TPB and HBM items applied to scat belt use. Structural equation modeling (SEM) techniques were used in analysis of the data. Results showed that the basic TPB model showed a good fit to the data whereas the extended TPB model and the HBM model fitted the data poorly. Within the basic TPB model, attitudes and subjective norm had a positive relationship to seat belt use intention for both urban and rural roads. Practical implications of the results for the seat belt use campaigns and traffic safety are discussed.


Relationship of seat belt use to health and driver behaviors
Simsekoglu, Ozlem; Lajunen, Timo (2009-05-01)
Seat belts are effective safety devices for protecting car occupants from injuries and fatalities in road vehicle accidents. Seat belt use has been reported to be related to some health and driving-related behaviors. The aim of the present study was to investigate to what degree seat belt use can be seen as health behavior or driver behavior. Participants were 252 licensed Turkish drivers (180 males, 72 females) with the mean age of 30.8 (SD = 12.15). A questionnaire including questions related to health-re...

Simsekoglu, Ozlem; Lajunen, Timo (2008-03-01)
Despite the effectiveness of seat belt use and legislation, seat belt use rate is low in Turkey. The aim of this study was to investigate the motives to use and not to use a seat belt in different traveling conditions in a sample of car drivers and passengers. Interviews were made face to face with 221 interviewees from different age and occupation groups. Frequently reported reasons for using a seat belt were traveling conditions, safety, situational conditions, habit of using a seat belt, and avoiding pun...
An approach to investigate relationship between speed and safety on urban arterials
Ardiç Eminağa, Zerrin; Akyılmaz, M. Özdemir; Department of Civil Engineering (2008)
Traffic safety is an important problem in today’s world with increasing number of fatalities and injuries in traffic accidents. For the solution of this problem, determination of accident prone locations on a network and reasons behind is an essential step, which is studied to some extend via different traffic accident analyses in the literature. While major factors affecting accident risk, such as speed, congestion, infrastructural aspects are known, it is still very difficult to figure out the interaction...
Can social psychological models be used to promote bicycle helmet use among teenagers? A comparison of the Health Belief Model, Theory of Planned Behavior and the Locus of Control
Lajunen, T; Rasanen, M (2004-01-01)
Problem: The bicycle helmet use rate is still low among teenagers despite the cumulating evidence that bicycle helmets can prevent cyclists from serious injuries and death. The objective of this study was to investigate the usefulness of the Health Belief Model (HBM; Health Education Monographs, 2 (1974) (1), Theory of Planned Behavior (TPB; Ajzen, I. (1988). Attitudes, personality and behavior. Open University Press, Milton Keynes) and Locus of Control model (LC; Psychological Monographs, (1966) (80) in un...
Job stress, burnout, and aberrant driving among professional drivers of old age
Fındık, Gizem; Lajunen, Timo; Department of Psychology (2016)
Commercial vehicles are involved in roughly 18% of all traffic accidents and 27% of all fatal traffic accidents in Turkey. These numbers highlight the need to investigate why professional drivers are involved in traffic accidents. Although the issue has often been on the agenda of the media, a similar impact occurred neither in scientific nor policy or applied domains yet. Therefore, the main purpose of this study is to investigate the relationship between job stress, burnout, and driving related outcomes (...
