Bibliometric analysis of the literature on phonological awareness in bilingual children

ABSTRACT Purpose: to characterize the profile of scientific production in the international literature on phonological awareness in bilingual children between 2011 and 2020. Methods: a bibliometric analysis was made with the search for articles in ERIC, LILACS, MEDLINE, and SciELO databases, using descriptors in English. The articles were selected based on the eligibility criteria, by reading the titles, then reading the abstracts, and lastly, reading the full-text articles. Results: a total of 1,167 articles were analyzed, 1,152 of which were excluded for not meeting the inclusion criteria. Hence, 15 articles were selected for full-text reading and bibliometric analysis. The United States was the country with most publications, followed by Brazil, Singapore, and China. The approach of the studies was predominantly quantitative, followed by qualitative; the most common type of study was cross-sectional, with samples of more than 100 participants. Conclusion: there was a greater number of publications in the last 3 years, most of them cross-sectional ones, presenting better phonological awareness performance among bilinguals, with positive results in reading.

摘要 目的：刻画2011至2020年间国际学界关于双语儿童语音意识（phonological awareness）的科研产出全貌。方法：采用文献计量分析方法，以英文检索主题词在ERIC、LILACS、MEDLINE及SciELO数据库中检索相关文献。文献筛选遵循纳入排除标准，依次通过标题初筛、摘要复筛及全文终审完成遴选。结果：本研究共纳入分析1167篇文献，其中1152篇因不符合纳入标准被剔除，最终筛选出15篇文献开展全文审阅与文献计量分析。发文量居首的国家为美国，依次为巴西、新加坡与中国。研究设计以定量研究为主，定性研究为辅；最常见的研究类型为横断面研究，样本量多超过100名受试者。结论：近三年发文量显著增长，其中绝大多数为横断面研究；双语儿童的语音意识表现更优异，且在阅读能力维度呈现积极研究结果。
