Abstract

Objective

The LittlEARS® Early Speech Production Questionnaire (LEESPQ) was developed to provide professionals with valuable information about children's earliest language development and has been successfully validated in several languages. This study aimed to validate the Serbian version of the LEESPQ in typically developing children and compare the results with validation studies in other languages.

Methods

The English version of the LEESPQ was back-translated into Serbian. Parents completed the questionnaire in paper or electronic form either during the visit to the paediatric clinic or through personal contact. A total of 206 completed questionnaires were collected. Standardized expected values were calculated using a second-order polynomial model for children up to 18 months of age to create a norm curve for the Serbian language. The results were then used to determine confidence intervals, with the lower limit being the critical limit for typical speech-language development. Finally, the results were compared with German and Canadian English developmental norms.

Results

The Serbian LEESPQ version showed high homogeneity (r = .622) and internal consistency (α = .882), indicating that it almost exclusively measures speech production ability. No significant difference in total score was found between male and female infants (U = 4429.500, p = .090), so it can be considered a gender-independent questionnaire. The results of the comparison between Serbian and German (U = 645.500, p = .673) and Serbian and English norm curves (U = 652.000, p = .725) show that the LEESPQ can be applied to different population groups, regardless of linguistic, cultural or sociological differences.

Conclusion

The LEESPQ is a valid, age-dependent and gender-independent questionnaire suitable for assessing early speech development in children aged from birth to 18 months.

验证塞尔维亚语版 LittlEARS® 早期言语表达能力问卷，以评估发育正常儿童的早期语言发展。

目的：LittlEARS® 早期语言表达能力问卷 (LEESPQ) 的开发旨在为专业人员提供有关儿童早期语言发展的宝贵信息，该问卷已成功通过多种语言的验证。本研究旨在对塞尔维亚语版的 LEESPQ 进行验证，并将结果与其他语言的验证研究结果进行比较：方法：将英语版的LEESPQ反译成塞尔维亚语。家长在儿科门诊就诊时或通过个人联系填写纸质或电子版问卷。共收集到 206 份填写完毕的问卷。我们使用二阶多项式模型计算了 18 个月以下儿童的标准化预期值，从而绘制出塞尔维亚语的标准曲线。然后根据结果确定置信区间，下限为典型言语-语言发展的临界值。最后，将结果与德国和加拿大的英语发展标准进行比较：塞尔维亚语 LEESPQ 版本显示出较高的同质性（r = .622）和内部一致性（α = .882），表明它几乎只测量言语表达能力。男婴和女婴的总分没有明显差异（U = 4429.500，p = .090），因此可以认为这是一份与性别无关的问卷。塞尔维亚语和德语（U = 645.500，p = .673）以及塞尔维亚语和英语常模曲线（U = 652.000，p = .725）之间的比较结果表明，LEESPQ可以适用于不同的人群，不受语言、文化或社会学差异的影响：结论：LEESPQ 是一份有效的、与年龄相关且与性别无关的问卷，适合评估出生至 18 个月儿童的早期言语发展。

期刊介绍： Child: care, health and development is an international, peer-reviewed journal which publishes papers dealing with all aspects of the health and development of children and young people. We aim to attract quantitative and qualitative research papers relevant to people from all disciplines working in child health. We welcome studies which examine the effects of social and environmental factors on health and development as well as those dealing with clinical issues, the organization of services and health policy. We particularly encourage the submission of studies related to those who are disadvantaged by physical, developmental, emotional and social problems. The journal also aims to collate important research findings and to provide a forum for discussion of global child health issues.
