Taha Hannachi is a dedicated PhD student focusing on the growing field of eco-anxiety, where he explores the psychological impacts of environmental crises. He holds a master’s degree in Social, Occupational, and Organizational Psychology from Rennes 2 University, where he honed his expertise in behavioral change within various social and work-related contexts. With over two years of experience in doctoral research and one year of research engineer experience, Taha has developed solid expertise in different methodological protocols and statistical analysis tests. The ecological transition and the psychological factors that might relate to it are the main area of interest of this young researcher.

Alain Somat holds a Ph.D. in cognitive psychology, specializing in individual and social behaviors. He is currently a university professor of experimental social psychology (with exceptional distinction). My research focuses on the individual and collective management of change. This primary theme leads me to work on three major issues in a world in transition: 1) the digital transition and its implications for work organization, 2) the generational transition and its implications for the care of elderly people in institutions, and 3) the ecological transition and its implications for individual and collective behavioral changes. In these three areas, I conduct both field and laboratory research to better understand the processes involved in implementing these transitions. Keywords: change, social acceptability, cognitive dissonance, skills. ANR funding: LUNNE, CMIO, SESAME, APIPRESUI, ACACIA ; Road Safety Directorate: SERENOS ; Region of Brittany: Eco-anxiety.

Abstract
The mental health impact of the environmental crisis, particularly eco-anxiety, is a growing research topic whose measurement still lacks consensus. This study aims to use item response theory (IRT) to gain a deeper understanding of the constructs measured by existing questionnaires. To conduct this review, we applied the graded response model with the help of the MIRT package in R on open-access data from the short French version of the Climate Change Anxiety Questionnaire, which measures cognitive–emotional impairment and functional impairment. The models tested in this study are the one, two, and three-factor models, and the bifactor model. After model selection, the psychometric properties of the selected model were tested. Our results suggest that the unidimensional model seems to be the most appropriate for measuring eco-anxiety. The item difficulty parameter extracted from the IRT enabled us to discuss the severity levels of the items comprising this tool. The Climate Change Anxiety Questionnaire appears to be more appropriate for measuring moderate to severe eco-anxiety. Avenues for improving this questionnaire and the measurement of eco-anxiety in general are then discussed.
