Table 1 Checklist for applying the Delphi model [36]
Planning | To define the researcher |
|---|---|
To develop the preliminary evaluation instrument and define the consultation objectives | |
To select the panelists | |
To perform a survey of the evidence in the literature on the chosen theme | |
To define what is established as consensus and threshold values | |
Execution | First round: Start with an open-ended questionnaire. The researcher structures the answers for the second round. When basic information is structured and available, an already structured questionnaire can be used in the first round (modified Delphi technique) |
Process and evaluate first-round results through statistical measures. Provide to the participants statistical feedback from the group | |
Subsequent rounds: each participant receives a questionnaire with the items from the previous round summarized by the researcher. Participants can review their opinions or justify them. Rounds can be stopped when the consensus level is reached |
