French Adaptation and Validation of the Pedestrian Receptivity Questionnaire for Fully Autonomous Vehicles (F-PRQF)

Abstract

This research is based on the adaptation and validation in French of the Pedestrian Receptivity Questionnaire for Fully Autonomous Vehicles (PRQF). Faced with the emergence of numerous issues related to interactions between pedestrians and fully autonomous vehicles (FAV), this questionnaire is a reliable and scientifically valid means of collecting pedestrian experiences when they cross a road in front of an autonomous vehicle. The translation methodology of the PRQF was based on a committee approach, which consisted of asking several bilingual experts to come to an agreement on a consensual translation. The validation of the French PRQF (F-PRQF) was based on the completion of 584 questionnaires. Different psychometric tests were carried out, including an accuracy analysis, a principal component factor analysis (PCA) and a confirmatory factor analysis (CFA). Our results show that the F-PQRF displays satisfactory psychometric qualities, in particular in terms of internal consistency (α = 0.932 and ω = 0.935). We also find a scale with five components, which confirms the theoretical model structure of the original scale. The F-PRQF showed good psychometric qualities, which should thus facilitate research in fully autonomous vehicles among French-speaking audiences.
