French adaptation and validation of the climate change anxiety scale
The notion of climate change anxiety has gained traction in the last years. Clayton & Karazia (2020) recently developed the 22-item Climate Change Anxiety Scale (CAS), which assesses climate change anxiety via a four-factor structure. Yet other research has cast doubts on the very structure of CAS by calling either for a shorter two-factor structure or for a shorter single-factor structure. So far, these different models have not yet been compared in one study. Moreover, uncertainty remains regarding the associations between the CAS and other psychological constructs, especially anxiety and depression. This project was designed to overcome these limitations. In a first preregistered study (n = 305), we adapted the scale into French and tested, via confirmatory factor analyses (CFA), whether the French version would better fit with a four-, a two-, or a single-factor structure implied by previous works. We also examined the relations of CAS factors with depression, anxiety, and environmental identity. In a second preregistered study, we aimed at replicating our comparison between the three models via CFA in a larger sample (n = 905). Both studies pointed to a 13-item version of the scale with a two-factor structure as the best fitting model, with one factor reflecting cognitive and emotional features of climate change anxiety and the other reflecting the related functional impairments. Each factor exhibited a positive association with depression and environmental identity but not with general anxiety. Implications of this two-factor structure for the conceptualization of climate change anxiety are discussed.
