The Mathematics Anxiety Rating Scale, A Brief Version: Psychometric Data (Suinn & Winston,2003)

Abstract: A measure of mathematics anxiety, the Mathematics Anxiety Rat- ing Scale (MARS) has been a major scale used for research and clinical studies since 1972. Despite the usefulness of the original scale, researchers have sought a 5horter version of the scale partly to reduce the administration time of the original 96.1tem scale. This study created a shorter version of the MARS and provides reliability and validity information for the new version. The Cronbach alpha of .96 indicated high in- internal consistency, while the test-retest reliability for the MARS 30-item was .90 ( p < ,001). The validity data confirm that h e MARS 30-item test is comparable to the original MARS 98-item scale.
