A personality questionnaire for elderly drivers did not predict driving performance. However, factor analysis revealed two key factors: Competence and Emotionality, offering insights into older adult personality traits.

Area of Science:

  • Gerontology
  • Psychology
  • Personality Research

Background:

  • Assessing driving performance in elderly individuals is crucial for public safety.
  • Personality traits may influence driving behavior, but empirical evidence is limited.
  • Developing reliable psychological assessments for older adults is an ongoing research area.

Purpose of the Study:

  • To investigate the factor structure of a personality questionnaire designed to predict driving performance in older adults.
  • To determine if specific personality factors correlate with driving skill in the elderly population.
  • To analyze the psychometric properties of a novel personality assessment tool for gerontology research.

Main Methods:

  • A 37-item personality questionnaire was administered to 191 participants aged 63 and older.

  • Factor analysis was employed to determine the underlying structure of the questionnaire.
  • A subset of participants underwent perceptual/cognitive tasks and a driving course assessment.

    • Main Results:

    • The personality questionnaire did not significantly predict driving skill in the elderly cohort.
    • Factor analysis yielded a robust two-factor solution.
    • The identified factors were interpreted as Competence and Emotionality, demonstrating approximate orthogonality.

    Conclusions:

    • The investigated personality questionnaire, in its current form, is not a predictor of driving performance in older adults.
    • The identified Competence and Emotionality factors provide a valuable structural understanding of personality in older individuals.
    • Further research is warranted to refine personality assessments for predicting driving safety in the elderly.
