Psychometric properties of abbreviated math anxiety scale in Russian high schoolers

Background. Math anxiety is a state of fear and anxiety that an individual experiences when interacting with mathematical problems. Currently, there is a lack of questionnaires to measure mathematical anxiety for Russian-speaking schoolchildren.The aim. The study analyzed the factor structure and psychometric properties of the Abbreviated Math Anxiety Scale (AMAS).Materials and methods. The study involved 1,198 schoolchildren in grades 10–11. The psychometric properties of the AMAS were analyzed.Results. AMAS demonstrated bifactor structure: subscales of Learning Math Anxiety (LMA) and Math Evaluation Anxiety (MEA) and general scale of Math Anxiety. The bifactor model demonstrated the best fit indices. Analysis confirmed reliable internal consistency (Cronbach’s alphas for LMA  =  0.82, MEA  =  0.75, total AMAS  =  0.95). External validity of AMAS has been confirmed. LMA showed lower scores than MEA. The distribution of scores on the general AMAS scale was shifted to low values. Girls showed higher scores on all scales of the questionnaire. The analysis also confirmed measurement invariance for both boys and girls.Conclusion. Based on the analysis, we can conclude that the AMAS is a valid tool for assessing mathematical anxiety in high school students.
