In the study Measuring outdoor recreationists' beliefs in climate change: testing the Occurrence and Anthropogenic Causational Scale (OC-AN), researchers used a survey of national park visitors in Alaska (n = 429), lake recreationists in the southeast U.S. (n = 210), and marine recreationists along the US Atlantic Coast (n=483) to understand recreationists' beliefs in climate change.
A scale was developed using two primary dimensions: occurrence - the belief that climate change is currently happening, and anthropogenic causation- the belief that climate change is caused by humans.
It was found that the two scales comprising the OC-AN have desirable measurement qualities within distinct and relatively diverse samples but the researchers also note that further development is needed.
