Participants' experiences with the Delphi method: an online evaluation of a three-round Delphi across German-speaking countries.

ABSTRACT:

Objectives

This study evaluates how participants experienced and assessed a three-round Delphi study on the terminology of developmental language disorders in childhood. It compares participants who completed all rounds (completers) with those who withdrew early (dropouts) and aims to derive methodological quality criteria for future Delphi studies.

Design

The evaluation is based on a Delphi study conducted in 2021/2022 across five German-speaking countries. After the final round, n=179 experts (40% response rate) completed a standardised survey assessing their expertise, motivation, reasons for discontinuation, time commitment and perceptions of questionnaire and feedback design. Responses from completers (n=156) and dropouts (n=23) were analysed descriptively.
