Not Only Reliability!

Abstract. The measurement of math anxiety in adults is justified based on observations that math anxiety in parents and teachers predicts children’s math anxiety and achievement. Although there are many very good math anxiety measures intended for children and adolescents, their usefulness (e.g., AMAS, MARS) for adults is debatable. The most important objection against using these scales for adults is their ecological validity. The measurement of anxiety associated with math tests, classes, teachers, and homework is adequate for students of science, technology, engineering, and mathematics (STEM), but not for students of social sciences and humanities (HS) and non-students (e.g., parents and preschool and early education teachers). In response to this gap, the Math Anxiety Questionnaire for Adults (MAQA) was developed; it is designed to measure math anxiety related to math problem-solving in various groups of adults (especially non-students and HS students, as well as STEM students). The content, construct, criterion, and ecological validity of the MAQA were tested, and its internal and test-retest reliability was established. The results confirm that the MAQA is a valid and reliable measurement of math anxiety; therefore, it may be recommended for use in various groups of adults (e.g., students, teachers, and parents).
