Preprint of the Delphi consensus survey paper

Highlights from the paper:

  • We report cross-sector consensus on how to document bilingual experience
  • 132 panellists from 29 countries participated in a Delphi consensus survey
  • The panel included researchers, speech and language therapists, and teachers
  • Consensus highlights the need for a common approach in quantifying bilingualism
  • We discuss implications for the creation of a new tool

The preprint is available via the OSF.

Preprint of our state-of-the-art paper

Highlights from the paper:

  • We review 48 questionnaires quantifying bilingualism in children
  • 32 constructs and 194 components across tools are identified. We report how frequently they are documented across questionnaires.
  • The review reveals low comparability in several estimates (e.g., exposure and use).
  • We argue for greater transparency and comparability of bilingualism measures

The preprint is available via the OSF.

Close of round 2 of the Delphi consensus survey

Out of the 164 panellists who had completed the first round, 132 completed the round 2 (80%). The data is being analysed, and the full report will be available in the Autumn.  We are immensely grateful to all the researchers and practitioners who invested their time and energy in the survey.

Launch of the 1st round of the Delphi consensus survey

We are most grateful to the 196 panellists (from 31 countries) who have agreed to take part in the Delphi consensus survey.  This includes 106 researchers, 58 speech & language therapists and 32 teachers.   The first round of the Delphi survey was launched on the 1st of April.

Panelists recruitment for the Delphi consensus survey

We are now recruiting panelists for the Delphi consensus survey.  Expressions of interest are invited from

  • Researchers specialising in the study of bilingual or multilingual children;
  • Speech and language therapists with a substantial proportion of bi-/multilingual children in their case-load;
  • Teachers working with bi-/multilingual children.

Closing date: 11th of March 2020 (23:59 GMT).  Further information is available here.

Delphi scoping workshop

In January 2020, we convened a workshop bringing together experts in bilingualism and language background questionnaires, as well as teachers and speech & language therapists who specialise in working with bilingual children. The aim was to inform the creation of the list of statements to be used in the survey.
