This study examined the test-retest reliability of the legibility portion of the Evaluation Tool of Children's Handwriting-Manuscript (ETCH-M).
The sample consisted of 31 first-grade and second-grade students with handwriting dysfunction. The ETCH-M was administered two times, 1 week apart, to participants. The primary investigator acted as sole rater and followed standard scoring procedures.
The reliability coefficients were .63 for total numeral legibility .77 for total letter legibility, and .71 for total word legibility. Individual task reliability coefficients were generally lower and ranged from .20 (near-point copy) to .76 (alphabet uppercase).
Total letter, total word, and uppercase letter legibility were more stable than total numeral legibility scores and other individual tasks scores. When evaluating handwriting for a child, it is important to consider ETCH legibility scores as only one aspect of a comprehensive evaluation.
本研究考察了儿童手写体评估工具（ETCH-M）易读性部分的重测信度。
样本包括31名患有书写功能障碍的一、二年级学生。研究人员对参与者进行了两次ETCH-M测试，每次测试间隔1周。主要研究者作为唯一评分者，并遵循标准评分程序。
总数字易读性的信度系数为0.63，总字母易读性的信度系数为0.77，总单词易读性的信度系数为0.71。各个任务的信度系数普遍较低，范围从0.20（近点抄写）到0.76（大写字母表）。
总字母、总单词和大写字母的易读性比分数字总易读性得分和其他单个任务得分更稳定。在评估儿童的书写时，重要的是要将ETCH易读性得分仅作为综合评估的一个方面来考虑。
