We discuss the theoretical and methodological limitationsof published attitudes toward science questionnaires and describe the development and validation of ashort instrument rooted in the cost construct of the expectancy-value model of achievement motivation. Wecollected data from a sample of six hundred thirty-two 5th and 6th (Mage = 10.87; SD = .76) elementary studentsin Spain. Exploratory and confirmatory factor analysis revealed a parsimonious structure measuring loss ofvalued alternatives and task effort cost. Further psychometric evaluation displayed evidence for convergent,discriminant, and concurrent validity. Likewise, the reliability was acceptable for both three-item scales. Thesefindings support the proposed instrument to measure barriers experienced by Spanish children when studyingschool science.
