Development and validation of the domain-specific climate change distress scale

Climate change is one of, if not the greatest, global challenges of this century, as its consequences can have a wide range of impacts on society, the environment, and the personal lives of many individuals. Consequently, many people experience severe psychological distress in the form of fears, anxieties, or worries, elicited by one, some, or all these different consequences. Thus, climate change distress can be conceptualized as a domain-specific construct. We conducted a literature review and a qualitative lay survey to develop the Domain-Specific Climate Change Distress Scale (DCCDS), with a generic climate change distress domain and six sub-domains (ecology, existence, food supply, future generations, society, and wealth). In the first study, we validated this structure with a bifactor-(S-1) model and refined the scale according to its psychometric properties. In a second study, we showed convergent and discriminant validity with the respective constructs. In a third study, we demonstrated the external validity of the scale by investigating the relation of its sub-domains to fear reactions to real-life news excerpts and willingness to donate to different charity organizations. Each sub-domain showed incremental validity over the generic domain. The scale had adequate psychometric properties and stability over three measurement timepoints in German gender-balanced convenience samples. We thus conclude that the domain-specific conceptualization of climate change distress yields important diagnostic benefits and could provide important insights into the future handling of climate change distress on a political, socio-cultural, and personal level.
