The aim of this longitudinal study was to investigate early vocabulary development and its relationships with prelinguistic communication skills and social-emotional/behavioral (SEB) problems and competencies. The participants were 58 healthy Finnish-speaking children (30 girls, 28 boys). First, the concurrent relationships were investigated at the age of 18 months. Second, the relationships between prelinguistic communication skills and SEB problems and competencies at 18 months, and subsequent vocabulary scores at 24 and 30 months, were examined. Parental reports on early vocabulary (MacArthur Communicative Developmental Inventories; MCDI), prelinguistic communication skills (The Infant-Toddler Checklist of the Communication and Symbolic Behavior Scales Developmental Profile; ITC), SEB problems and competencies (Brief Infant-Toddler Social and Emotional Assessment; BITSEA) were gathered. Compared to boys, girls scored significantly higher on ITC Speech Composite at 18 months and expressive vocabulary measures at 18, 24, and 30 months. Vocabulary, as well as prelinguistic communication measures, correlated with SEB competencies at 18 months. Furthermore, vocabulary, as well as ITC Symbolic Composite and Total Score, correlated negatively with externalizing problem and SEB Total Problem scores. With regard to subsequent vocabulary development, all of the prelinguistic communication measures at 18 months correlated with vocabulary at 24 and 30 months. However, when accounted for gender and earlier vocabulary, only the associations with ITC Speech Composite and Total Score at 24 months remained significant. SEB Competencies at 18 months correlated positively, while externalizing problems at 18 months correlated negatively with vocabulary at 24 and 30 months, however, these associations did not remain significant, when accounted for gender and earlier vocabulary.
本纵向研究旨在探讨早期词汇发展及其与前语言沟通技能以及社会情感/行为（SEB）问题和能力的关系。参与者为 58 名健康的芬兰语儿童（30 名女孩，28 名男孩）。首先，在 18 个月时研究了同期关系。其次，研究了 18 个月时的前语言沟通技能和 SEB 问题与能力与 24 个月和 30 个月时词汇得分之间的关系。通过家长报告收集了早期词汇（麦克阿瑟沟通发展量表；MCDI）、前语言沟通技能（沟通与象征行为量表发展概况婴儿-幼儿检查表；ITC）、SEB 问题和能力（婴儿-幼儿简要社交和情感评估；BITSEA）。与男孩相比，女孩在 18 个月时 ITC 言语综合得分和 18、24 和 30 个月时表达性词汇得分显著更高。词汇以及前语言沟通测量与 18 个月时的 SEB 能力相关。此外，词汇以及 ITC 象征综合和总分与外化问题和 SEB 总分呈负相关。关于随后的词汇发展，18 个月时的所有前语言沟通测量均与 24 个月和 30 个月时的词汇相关。然而，当考虑到性别和早期词汇时，只有与 24 个月时的 ITC 言语综合和总分的关联仍然显著。18 个月时的 SEB 能力呈正相关，而 18 个月时的外化问题与 24 个月和 30 个月时的词汇呈负相关，然而，当考虑到性别和早期词汇时，这些关联不再显著。
