Development of the global climate crisis risk perception scale (GCCRP-S): A validity and reliability study.

Despite the increasing scientific data on the causes and effects of the global climate crisis, it is seen that the perceptions, approaches, practices, views and opinions of both governments, some organizations and institutions, and individuals and societies are divided. In order to clearly reveal this situation, this study develops a global climate crisis risk perception scale. A methodological research was carried out in 8 stages: determining the boundaries of the concept/structure; creating of the item pool; submitting the item pool to expert opinion; pilot study; preparation of the data collection tool; main application with large group; test-retest application; statistical analysis and finalization of GCCRP-S. The draft scale was applied at face-to-face interviews with 749 participants. Content, Face, Construct and Concurrent Validity were evaluated to determine validity. Internal consistency and stability tests were used to determine reliability. A five-factor structure emerged that explained 69.40% of the variance. Goodness of fit indices were within the values reported in the literature. The Cronbach's alpha coefficient, which shows the internal consistency, was 0.957. The intraclass correlation coefficient, indicating the stability, was 0.940. The GCCRP-S provides an initial multidimensional framework for examining global climate crisis risk perception in adults. Following validation in independent and more diverse populations, it may support future research and provide contextual evidence for climate-risk communication and policy discussions.
