The Climate Change Worry Scale (CCWS) and Its Links with Demographics and Mental Health Outcomes in a Polish Sample.

Developing valid and reliable measures of psychological responses to climate change is of high importance, as this facilitates our understanding of people's psychological responses, including their pro-environmental behavior. Recently, the Climate Change Worry Scale (CCWS) was introduced. This study aimed to develop the first Polish version of the CCWS and explore its psychometric properties. Our sample comprised 420 Polish adults aged 18-70, with a mean age of 26.20 (standard deviation = 10.61) years. The CCWS's factor structure was assessed with confirmatory factor analysis. McDonald's omega and Cronbach's alpha coefficients were computed to assess internal consistency reliability. Pearson correlations between climate change worry (CCW) and experience of climate change (i.e., an individual's level of perception of being affected by climate change), pro-environmental behavior, ill-being (i.e., anxiety and depression symptoms), and well-being were calculated. Our results support the strong factorial validity of the CCWS, conforming to its intended one-factor solution, with excellent internal consistency reliability for the total scale score (i.e., McDonald's omega and Cronbach's alpha values of 0.93). We noted large positive correlations between CCW and experiences of climate change, as well as pro-environmental behavior, and medium positive correlations with psychopathology symptoms. CCW scores were not associated with well-being. As the CCWS represents a measure of a specific manifestation of worry, we also examined its discriminant validity against more general psychological distress markers, and it evidenced strong validity in this regard. Overall, the Polish version of the CCWS appears to have strong psychometric properties, and will therefore be a useful tool to use in research on psychological responses to climate change.
