Psychometric validation of the climate anxiety scale in spanish adolescents and adults
摘要
Climate anxiety reflects the distress caused by climate change. The climate anxiety scale (CAS) was developed in 2020 to be used in the USA. It includes two factors: Cognitive-emotional impairment and Functional impairment. However, there is controversy regarding the scale’s psychometric properties, including its dimensionality, leading to a call for efforts to better understand the CAS in different contexts. We conducted two consecutive studies, with adolescents (Study 1; N = 1252, Mage = 14.54; SD = 1.78) and adults (Study 2; N = 528; Mage = 43.90; SD = 16.12), to validate the CAS in Spain. The two-factor structure originally proposed adequately fits our data, and climate anxiety is positively associated with general anxiety and depression, nature relatedness, inclusion of nature in self, environmental efficacy, and pro-environmental behaviors. Members of environmental organizations reported higher climate anxiety than non-members. Thus, our findings support the scale’s structural, convergent and criterion validity. The CAS is a reliable instrument that might facilitate the assessment of climate-related distress.
