Summary
The Manchester Driver Behaviour Questionnaire (DBQ) structure was largely replicated in Finland and The Netherlands, confirming its cross-cultural applicability in assessing driver behaviors and errors.
Area of Science:
- Psychology
- Transportation Science
- Road Safety
Background:
- The Manchester Driver Behaviour Questionnaire (DBQ) is a widely used tool for assessing driver behaviors.
- Understanding the cross-cultural validity of such instruments is crucial for global road safety research.
Purpose of the Study:
- To examine the factorial structure of the original Manchester Driver Behaviour Questionnaire (DBQ).
- To assess the replicability of the DBQ's structure in Finland and The Netherlands compared to Britain.
Main Methods:
- A postal questionnaire survey was administered to drivers in Britain, Finland, and The Netherlands.
- Exploratory factor analysis, target (Procrustes) rotation, and factorial agreement indexes were employed.
- Scale reliabilities were calculated for the Finnish and Dutch versions.
Main Results:
- The four-factor structure of the DBQ in Finland and The Netherlands showed congruence with the British structure.
- Scale reliabilities in Finland and The Netherlands were comparable to British data.
- Two second-order factors (deliberate violations and unintentional errors) were identified across all three countries.
Conclusions:
- The findings support the original factorial structure of the DBQ by Reason et al.
- The DBQ demonstrates good cross-cultural applicability for assessing driver behavior in different national contexts.
- Further research should consider nuances in cross-cultural traffic behavior questionnaire use.
