虽然大多数双语研究记录了参与者的语言背景，但对于如何量化双语缺乏共识。研究人员和从业人员使用的大量不同语言背景的调查问卷，损害了数据的可比性和研究与实践之间的相互影响。使用德尔菲共识调查方法，我们要求来自29个国家的132名小组成员（研究人员，言语和语言治疗师，教师）对124个陈述进行5点一致性评分。共识预定义为75%的一致性阈值。经过两轮调查，79%的陈述达成了共识。96%的受访者承认需要采取共同措施来量化双语。各方同意记录以下内容：语言接触和使用、语言困难、熟练程度（无法直接评估时）、教育和识字、输入质量、语言混合做法和态度（对语言和语言混合）。我们讨论了这些发现的影响，创造一个新的工具来量化双语经验。
While most investigations of bilingualism document participants' language background, there is an absence of consensus on how to quantify bilingualism. The high number of different language background questionnaires used by researchers and practitioners jeopardises data comparability and cross-pollination between research and practice. Using the Delphi consensus survey method, we asked 132 panellists (researchers, speech and language therapists, teachers) from 29 countries to rate 124 statements on a 5-point agreement scale. Consensus was pre-defined as 75% agreement threshold. After two survey rounds, 79% of statements reached consensus. The need for common measures to quantify bilingualism was acknowledged by 96% of respondents. Agreement was reached to document: language exposure and use, language difficulties, proficiency (when it cannot be assessed directly), education and literacy, input quality, language mixing practices, and attitudes (towards languages and language mixing). We discuss the implications of these findings for the creation of a new tool to quantify bilingual experience.
