The Mathematics Anxiety Rating Scale: Psychometric data.

Reports normative, reliability, and validity data for the Mathematics Anxiety Rating Scale (MARS), a measure of mathematics anxiety for use in treatment and research. Normative data were collected on a sample of 397 undergraduates. The instrument has high test-retest and internal consistency reliability. Evidence for validity comes from 3 studies in which MARS scores showed expected decreases following behavior therapy for mathematics anxiety, and a separate validity study in which MARS scores were found to correlate negatively with scores on a mathematics test. Possible uses of the instrument in treatment and research are discussed. (17 ref.) (PsycINFO Database Record (c) 2006 APA, all rights reserved)
