Processed survey data on eco-anxiety, subjective well-being, and pro-environmental behavior (Ukraine, N=309)

Participants were recruited through a snowball sampling method, beginning with initial respondents who completed an online questionnaire and were subsequently asked to share the survey link with their personal networks. Data were collected from March 14 to April 22, 2024, using Google Forms. All participants gave their consent electronically before taking part in the study and agreed that their anonymous answers could be used for research. Some personal information like email addresses and last names was collected only for administrative reasons but was kept safe and not used in the analysis. This method helped to gather a diverse group of Ukrainian adults. All identifying information was removed or protected before data analysis to ensure privacy. The study was approved by the Ethics Committee of the Faculty of Psychology at V. N. Karazin Kharkiv National University on February 28, 2023 (meeting minutes No. 9).

The current dataset represents a processed version of the original responses. The data were coded in accordance with the official scoring guidelines of the psychological scales used in the study.

In this processed dataset, the variables include PA for positive affect, NA for negative affect, SWL for satisfaction with life, AffecSympt for affective symptoms of eco-anxiety, Rumination for rumination, BehSympt for behavioral symptoms of eco-anxiety, AnxPersImpact for anxiety about personal impact, and pro-environmental variables labeled as behavior.
