Psychometric properties of mathematics anxiety measures have not adequately been studied. Using a large sample size (N = 1,239), the authors developed an abbreviated math anxiety measure, examined its psychometric properties, and assessed the generalizability of the model across samples. Exploratory factor analysis yielded a nine-item measure and strong internal consistency, test-retest reliability, and good convergent/divergent validity was demonstrated with an independent sample. When administered to a replication sample, indexes suggested an excellent model fit. TheAbbreviated Math Anxiety Scale (AMAS) may represent a more parsimonious and valid approach to assess mathematics anxiety.
数学焦虑测量工具的心理测量特性尚未得到充分研究。作者使用大样本量（N = 1239）开发了一种简化的数学焦虑测量工具，检验了其心理测量特性，并评估了该模型在不同样本中的通用性。探索性因素分析得出了一个包含九个条目的测量工具，具有很强的内部一致性、重测信度，并且在一个独立样本中证明了良好的聚合效度/区分效度。当应用于一个重复样本时，各项指标表明模型拟合度极佳。简化数学焦虑量表（AMAS）可能是一种更简洁有效的评估数学焦虑的方法。
