International audience. Objective : Eco-anxiety is a complex construct that has been created to grasp the psychological impact of the consequences of global warming. The concept needs a reliably valid questionnaire to better evaluate its impact on the risk of anxiety and depressive disorders. The Eco-Anxiety Questionnaire (EAQ-22) evaluates two dimensions : " habitual ecological anxiety " and " distress related to eco-anxiety ". However, a version in French, one of the world's widely spoken languages, was until now lacking. We aimed to translate and validate the French EAQ-22 and to evaluate the prevalence of the level of the two dimensions of eco-anxiety and the relationship with anxiety and depressive symptoms in a representative adult sample of the French general population. Methods : This study was performed under the auspices of the Institut national du sommeil et de la vigilance (INSV). Participants (18-65 years) were recruited by an institute specialized in conducting online surveys of representative population samples (quota sampling). Two native French speakers and two native English speakers performed a forward-backward translation of the questionnaire. The Hospital Anxiety and Depression scale (HAD) was administered to assess anxiety (HAD-A) and depressive (HAD-D) symptoms and for external validity. Internal structural validity and external validity were analysed. Results : Evaluation was performed on 1004 participants: mean age 43.47 years (SD = 13.41, range: [19-66]); 54.1% (n = 543) women. Using the HAD, 312 (31.1%) patients had current clinically significant anxiety symptoms (HAD-A > 10) and 150 (14.9%) had current clinically significant depressive symptoms (HAD-D>10). Cronbach s alpha coefficient was 0.934, indicating very good internal consistency. Correlation between EAQ-22 and HAD scores was low (r[1004] = 0.209, P < 0.001), u2018habitual ecological anxietyu2019 was correlated less with HAD-A and HAD-D than u2018distress related to eco-anxietyu2019, indicating good external validity. Conclusion : This study validates the French EAQ-22 and paves the way for using the EAQ-22 as a global tool for assessing eco-anxiety. Further prospective studies are now required to better evaluate the impact of eco-anxiety on the occurrence of anxiety and depressive disorder.
