替代模型的个人结构和发展差异的书面组成和手写流畅性进行了测试，使用验证性因素分析的写作样本提供的一年级和四年级的学生。对于这两组，五因素模型提供了最佳拟合的数据。其中四个因素代表了写作的各个方面：宏观组织（使用顶句和想法的数量和顺序），生产力（使用的单词的数量和多样性），复杂性（T单位的平均长度和句法密度），以及拼写和标点符号。第五个因素代表书写流畅性。在这两个等级的书写流畅性与书面组成因素。一年级和四年级之间的发展差异的幅度表示为影响大小不同的变量代表的五个结构：大的影响大小被发现的生产力和手写流畅性变量;中等影响大小被发现的复杂性和宏观组织变量;和最小的影响大小被发现的拼写和标点变量。
Alternative models of the structure of individual and developmental differences of written composition and handwriting fluency were tested using confirmatory factor analysis of writing samples provided by first- and fourth-grade students. For both groups, a five-factor model provided the best fit to the data. Four of the factors represented aspects of written composition: macro-organization (use of top sentence and number and ordering of ideas), productivity (number and diversity of words used), complexity (mean length of T-unit and syntactic density), and spelling and punctuation. The fifth factor represented handwriting fluency. Handwriting fluency was correlated with written composition factors at both grades. The magnitude of developmental differences between first grade and fourth grade expressed as effect sizes varied for variables representing the five constructs: large effect sizes were found for productivity and handwriting fluency variables; moderate effect sizes were found for complexity and macro-organization variables; and minimal effect sizes were found for spelling and punctuation variables.
