ABSTRACT The present study analyzes the psychometric properties of a Spanish-adapted version of the Working Memory Rating Scale (WMRS). This instrument allows teachers to perform a screening of children with possible working memory (WM) difficulties, putting them at risk of academic underachievement. A sample of children age 8.5 to 12.33 years old was evaluated with the WMRS, objective WM measures, and academic skills measures. Results indicated that WMRS scores were negatively correlated with objective WM and academic measures. Confirmatory factor analysis showed that a one-factor model had an adequate fit, and that the complete version of the scale was comparatively better than a short 5-item version. The WMRS was effective in differentiating children with low and average WM. These results indicate that the Spanish version of the WMRS presented adequate psychometric properties, and may be useful for teachers in Latin America for screening children with WM difficulties.

拉丁美洲儿童的工作记忆筛查：工作记忆等级量表的西班牙语版的心理计量学特性

摘要本研究分析了西班牙文版的工作记忆量表（WMRS）的心理测量特性。该工具可使教师对可能存在工作记忆（WM）困难的孩子进行筛查，使他们处于学业成绩不佳的风险中。使用WMRS，客观的WM度量和学业技能度量对8.5至12.33岁的儿童进行了评估。结果表明，WMRS得分与客观WM和学业成绩呈负相关。验证性因素分析表明，单因素模型具有足够的拟合度，并且完整版的量表比简短的5项版更好。WMRS可有效区分WM低和平均的儿童。
