The notion of climate anxiety has gained traction in the last years. Yet uncertainty remains regarding the variations of climate anxiety across demographic characteristics (e.g., gender, age) and its associations with adaptive (i.e., pro-environmental) behaviors. Moreover, the point-estimate proportion of people frequently experiencing climate anxi...

To study, at a national level, the emotional cost and psychosocial responses of Spanish citizens to the COVID-19 health emergency. We aim to assess a wide variety of psychosocial responses, including positive dimensions (e.g., resilience, positive emotions, and perceived benefits) and negative ones (e.g., depression,anxiety and posttraumatic stress symptoms) related to current mental healthstatus. Besides, as psychological reactionsmust be understood by considering social and environmental factors, we also aim to assess political attitudes as well asspecific characteristics related to the COVID-19, such asthe degree of exposure to the virus,concerns related to the pandemic,and general political attitudes(e.g., authoritarism, attitudes towards immigrants, nationalism, etc.) https://osf.io/2y45r
