Testing sex-related measurement invariance in science self-efficacy in large-scale assessments. Annual Conference of American Educational Research Association (AERA) 2025, Denver, CO, United States.https://convention2.allacademic.com/one/aera/aera25/index.php?cmd=Online+Program+View+Paper&selected_paper_id=2178541&PHPSESSID=9e63vqqptt6snp8oun2m55gn21http://hdl.handle.net/20.500.11861/26502The present study investigates the measurement invariance of science self-efficacy across sexes among U.S. adolescents using data from the Programme for International Student Assessment (PISA) 2006 and PISA 2015. Employing a multigroup confirmatory factor analysis within the framework set by Kane (2013), this study tests whether the science self-efficacy scale operates equivalently for female and male participants. Findings indicated configural, metric and scalar invariance which revealed that the science self-efficacy scale's items are interpreted similarly across sexes in both PISA 2006 and PISA 2015 and that comparisons of science self-efficacy scores between males and females are valid. These findings suggested the science self-efficacy scale's fairness in assessing science self-efficacy where contributes to the understanding of sex disparities in STEM fields.enConference Paper
