This study developed the Brief Math Anxiety Scale (BMAS), a brief version of the Shortened Math Anxiety Rating Scale (sMARS), maintaining its original three-factor structure, by applying item response theory.
The sMARS was administered to 1,349 undergraduates, along with other questionnaires to measure their math ability, trait and test anxieties, and attitudes toward mathematics.
Results showed that the original scale could be reduced to nine items (three for each subscale). We provided evidence of good psychometric properties: strong internal consistency, adequate 7-week test-retest reliability, and good convergent/discriminant validity.
In conclusion, the BMAS provides valid interpretations and reliable scores for assessing math anxiety in university students, and is especially useful in situations with time constraints where the longer form is impractical.
本研究运用项目反应理论，从缩短版数学焦虑量表（sMARS）中发展出简短版数学焦虑量表（BMAS），保留了其原有的三因素结构。
对 1349 名本科生进行了 sMARS 测试，以及其他问卷来衡量他们的数学能力、特质和考试焦虑以及对数学的态度。
结果表明，原始量表可以简化为九个项目（每个分量表三个）。我们提供了良好的心理测量学特性的证据：较强的内部一致性、足够的 7 周重测信度和良好的聚合/区分效度。
总之，BMAS 为评估大学生的数学焦虑提供了有效的解释和可靠的分数，特别是在时间紧张的情况下，使用较长的量表不切实际时，更为有用。
