This study develops and examines the psychometric properties of the Scientific Reasoning Scale (SRS) in Japanese, based on the SRS developed by Drummond and Fischhoff (2017). People of different ages were asked to complete the survey: adults ( = 343; Study 1), university students ( = 93; Study 2), and high school students ( = 250; Study 3). Analysis using item response theory suggests that the SRS has a unidimensional structure and can capture individual differences among people with a wide range of abilities, from high to low scientific reasoning ability. The results also suggest that scores on the SRS were positively correlated to factual knowledge of science, critical thinking dispositions, and openness of experiences, suggesting that it is a valid measure of scientific reasoning ability. Although the results were not consistent for the relationship between the SRS and reasoning ability assessed by a syllogism-solving test, the results revealed a positive correlation between them in high school students, partially supporting the validity of the scale. Based on the psychometric properties of the SRS in Japanese, we discuss considerations in using it to assess scientific reasoning ability and in improving and expanding the item set of the SRS.
