The driver’s personality is a key human factor for the assessment of the fitness to drive (FTD), affecting driving decisions and behavior, with consequences on driving safety.

The present study aimed to compare two MMPI‐2‐based models of normal and pathological personality traits (i.e., Inventory of Driving‐related Personality Traits (IVPE)‐MMPI vs. Personality Psychopathology Five (PSY‐5) scale) in predicting the cognitive FTD. One hundred young and eighty‐seven adult active drivers completed the MMPI‐2 questionnaire as a measure of personality and a computerized driving task measuring for resilience of attention (Determination Test (DT)), reaction speed (Reaction Test (RS)), motor speed (MS), and perceptual speed (Adaptive Tachistoscopic Traffic Perception Test (ATAVT)). The effects of age, gender, and education were also controlled. Results showed that the models controlled for demographics overperformed those neglecting them for each driving outcome. A negative effect of age was found on each driving task; the effect of gender, favoring males, was found in both the RS and the MS, and the effect of education was found on the DT and the ATAVT. Concerning personality traits, significant effects were found of sensation seeking (IVPE‐MMPI) on each outcome; of anxiety (as a measure of emotional instability; IVPE‐MMPI) and introversion (PSY‐5) on the measures of MT; and of psychopathic deviation (as a measure of self‐control; IVPEMMPI) on the DT. The study confirmed the key role of demographic factors in influencing the FTD, further suggesting the usefulness of some MMPI2‐based personality scales in the assessment of driving‐related personality determinants.

Abstract

The driver’s personality is a key human factor for the assessment of the fitness to drive (FTD), affecting driving decisions and behavior, with consequences on driving safety. No previous study has investigated the effectiveness of Minnesota Multiphasic Personality Inventory (MMPI)‐2 scales for predicting the FTD. The present study aimed to compare two MMPI‐2‐based models of normal and pathological personality traits (i.e., Inventory of Driving‐related Personality Traits (IVPE)‐MMPI vs. Personality Psychopathology Five (PSY‐5) scale) in predicting the cognitive FTD. One hundred young and eighty‐seven adult active drivers completed the MMPI‐2 questionnaire as a measure of personality and a computerized driving task measuring for resilience of attention (Determination Test (DT)), reaction speed (Reaction Test (RS)), motor speed (MS), and perceptual speed (Adaptive Tachistoscopic Traffic Perception Test (ATAVT)). The effects of age, gender, and education were also controlled. Results showed that the models controlled for demographics overperformed those neglecting them for each driving outcome. A negative effect of age was found on each driving task; the effect of gender, favoring males, was found in both the RS and the MS, and the effect of education was found on the DT and the ATAVT. Concerning personality traits, significant effects were found of sensation seeking (IVPE‐MMPI) on each outcome; of anxiety (as a measure of emotional instability; IVPE‐MMPI) and introversion (PSY‐5) on the measures of MT; and of psychopathic deviation (as a measure of self‐control; IVPEMMPI) on the DT. The study confirmed the key role of demographic factors in influencing the FTD, further suggesting the usefulness of some MMPI2‐based personality scales in the assessment of driving‐related personality determinants.
