The authors tested associations between (a) parent-reported temporary vs. persistent vocabulary delay and (b) parent-reported behavioral/emotional problems in a sample of 5,497 young Dutch children participating in a prospective population-based study.
Mothers completed the MacArthur Communicative Development Inventory-Netherlands (Zink & Lejaegere, 2003) at age 18 months and the Language Development Survey (Rescorla, 1989) at age 30 months, with expressive vocabulary delay defined as scores in the lowest 15th age- and gender-specific percentiles. The Child Behavior Checklist (Achenbach & Rescorla, 2000) was completed by mothers when their children were age 18 months and by both parents when their children were age 36 months, from which Internalizing Problems and Externalizing Problems scores were analyzed.
All analyses were adjusted for covariates. Expressive vocabulary delay at age 18 months was weakly related to Internalizing Problems scores at age 18 months as well as mother-reported Externalizing and Internalizing Problems scores at age 36 months (the latter for boys only). Expressive vocabulary delay at age 30 months was weakly associated with mother-reported Externalizing and Internalizing Problems scores (the latter for boys only) and father-reported Internalizing Problems scores. Persistent expressive vocabulary delay predicted the highest risk of mother-reported internalizing and externalizing problems at age 36 months.
This population-based study showed modest associations between vocabulary delay and behavioral/emotional problems detectable from 18 months onward.
作者在一个参加前瞻性基于人群研究的 5497 名年轻荷兰儿童样本中，检验了（a）父母报告的暂时性与持久性词汇延迟与（b）父母报告的行为/情绪问题之间的关联。
母亲在 18 个月时完成了麦克阿瑟交际发展量表-荷兰语版（Zink & Lejaegere，2003），在 30 个月时完成了语言发展调查（Rescorla，1989），表达性词汇延迟的定义为得分处于最低的 15%年龄和性别特定百分位数。当孩子 18 个月大时，母亲填写儿童行为检查表（Achenbach & Rescorla，2000），当孩子 36 个月大时，父母双方都填写该表，从该表中分析内化问题和外化问题的分数。
所有分析均调整了协变量。18 个月时的表达性词汇延迟与 18 个月时的内化问题评分以及 36 个月时母亲报告的外化和内化问题评分（仅男孩）呈弱相关。30 个月时的表达性词汇延迟与母亲报告的外化和内化问题评分（仅男孩）以及父亲报告的内化问题评分呈弱相关。持续性表达性词汇延迟预测了 36 个月时母亲报告的内化和外化问题的最高风险。
这项基于人群的研究表明，词汇延迟与从 18 个月起可检测到的行为/情绪问题之间存在适度关联。
