A Follow up on the Continuum Theory of Eco-Anxiety: Analysis of the Climate Change Anxiety Scale Using Item Response Theory among French Speaking Population
Summary
This study investigates how to best measure eco-anxiety, which is the worry or distress people feel about climate change. Researchers analyzed a questionnaire called the Climate Change Anxiety Scale (CCAS) to see if it accurately captures different levels of eco-anxiety, from mild concern to severe distress. They used a statistical method to determine whether the CCAS measures eco-anxiety as a single, continuous experience or as a set of separate factors.
The study’s findings suggest that the CCAS primarily measures eco-anxiety as a single concept, rather than breaking it down into different components. It also showed that the CCAS is better at identifying people with moderate to severe eco-anxiety, and may not be sensitive enough to detect milder levels of worry. The researchers conclude that while the CCAS is a useful tool, it could be improved to better understand the full range of eco-anxiety experiences.
