Abstract
This study presents initial work to validate a scale designed to measure scientists’ outcome expectations in relation to public engagement. A 20-item survey was administered to a sample of 341 scientists. Graded response models were used to assess the quality of the items. Results suggest that six items provided the strongest measure of outcome expectations, with classically adequate reliability across a wide range of scientists and scores. The findings are presented in relation to the short-term outcomes of public engagement for scientists and the need for validated scales that allow for the continued study of science communication efforts.
