Exploratory study toward development of the French version of the questionnaire on personality traits (QPT/VKP-4) in an elderly population in comparison to young adults.

This research is an exploratory study toward development of the French version of the Questionnaire on Personality Traits (QPT/VKP-4). The goal was to assess its association with the Big Five Inventory (BIG-5) and to explore the personality characteristics of the elderly compared to young adults. The 241 participants included 83 elderly people and 158 young adults. Borderline and anxious personality disorders were less frequent in elderly women than in young women, and depressive personality disorder was less frequent in elderly men. Dimension scores were higher for Conscientiousness in the elderly, Agreeableness in elderly women, and Extraversion in elderly men. Statistically significant correlations were found between personality dimension scores using the VKP-4 and the BIG-5.
