RT info:eu-repo/semantics/article T1 Cultural Adaptation of the Expectancy-Value-Cost Scale for Spanish-Speaking Students A1 Toma, Radu Bogdan K1 Achievement motivation K1 Evaluation methods K1 Expectancy values K1 Cost K1 Validity K1 Psicología K1 Psychology K1 Enseñanza primaria K1 Education, Primary AB The Expectancy-Value model has been extensively used to understand students' achievement motivation. However, recent studies propose the inclusion of cost as a separate construct from values, leading to the development of the Expectancy-Value-Cost model. This study aimed to adapt Kosovich et al.’s (The Journal of Early Adolescence, 35, 5–6, 2015) instrument for assessing achievement motivation in science and math among Spanish-speaking students aged 9–12. The psychometric evaluation encompassed examining validity, reliability, and measurement invariance for gender. The findings support the applicability of the expectancy-value-cost model in elementary school students, providing a valid and reliable tool for assessing achievement motivation in the science and math domain. However, the findings for the measurement invariance for gender are less conclusive and warrant future psychometric evaluations. This study opens avenues for future research on achievement motivation in Spanish-speaking contexts and populations.
