Driver behavior patterns, measured by the Driver Behaviour Questionnaire (DBQ), showed significant changes over three years, with a two-factor solution demonstrating better stability. Young males and middle-aged females exhibited the most notable shifts in driving habits.

Area of Science:

  • Psychology
  • Transportation Science
  • Road Safety

Background:

  • The Driver Behaviour Questionnaire (DBQ) is a key tool for assessing self-reported driving patterns.
  • Understanding the stability of DBQ factor structures over time is crucial for accurate driver behavior analysis.
  • Previous research has not fully explored the longitudinal stability of DBQ factor solutions.

Purpose of the Study:

  • To investigate the time-across stability of different factor solutions (2-6 factors) of the Driver Behaviour Questionnaire (DBQ).
  • To examine changes in self-reported driving patterns over a three-year period.
  • To identify demographic groups exhibiting significant changes in driving behavior.

Main Methods:

  • A longitudinal study with a follow-up sample (n=622) after three years.

  • Repeated measures ANOVA was used to analyze changes in DBQ scores between Time 1 and Time 2.
  • Tucker's Phi agreement coefficients were employed to assess the stability of factor solutions.
  • Main Results:

    • Significant changes were observed in six DBQ items, including increased speeding and decreased competitiveness.
    • Young males and middle-aged females showed the most significant changes in self-reported driving patterns.
    • The two-factor and four-factor solutions demonstrated the most stability, with the two-factor solution being more stable over time.
    • High annual mileage correlated with stronger two-factor time-across stability.

    Conclusions:

    • The DBQ factor structure exhibits moderate stability over three years, with the two-factor solution being the most reliable.
    • Specific demographic groups, notably young males and middle-aged females, demonstrate evolving driving behaviors.
    • Findings underscore the dynamic nature of driver behavior and the importance of longitudinal assessment.
