Résumé	The Mathematics Anxiety Rating Scale (MARS) is a self-report questionnaire assessing anxiety and worry related to mathematics learning and performance. Originally developed by Plake and Parker in 1982 with 98 items and refined to a 30-item version (MARS-30) in 1995, the MARS measures multiple facets of math anxiety: anxiety in test/evaluation contexts, mathematics learning contexts, and everyday numerical situations. It is widely used in educational psychology, mathematics education research, and clinical assessment to identify students with math anxiety and to evaluate interventions.	The Anxiety Sensitivity Index–3 (ASI-3) is an 18-item self-report questionnaire that measures anxiety sensitivity—the tendency to fear bodily sensations and interpret them as signs of impending threat. Developed by Taylor and colleagues in 2007, it distinguishes between three domains of anxiety sensitivity: physical, cognitive, and social. The ASI-3 is widely used in research and clinical assessment to identify individuals at risk for anxiety disorders, panic disorder, and post-traumatic stress.
