Table 2 The modified nominal group technique process

(i) Generating ideas

Members of the group will be asked to individually consider the data that has been presented to them and consider:

1. If there is there a need for an evaluation study of the co-designed interventions and if so;

2. Ideas for the potential design of an evaluation study of the co-designed interventions.

(ii) Recording ideas

Group members engage in a round-robin feedback session to concisely record each idea (without debate).

If it becomes apparent that the consensus is not to proceed to an evaluation study, the NGT will cease at this stage. If it is decided that an evaluation study should be designed based on the data from phases 1–3, member of the group will be asked to share their ideas for the potential design of an evaluation study of the co-designed interventions.

(iii) Clarification

A discussion focussed on clarification of the ideas generated.

(iv) Voting

Individual group members vote privately to rank ideas. The votes will be tallied to identify the ideas that are rated highest by the group as a whole and will then be presented back to the group.

(v) Discussion

A group discussion to provide further clarification of the highest rated ideas for the future evaluation study of the co-designed interventions.

(vi) Re-ranking

Re-ranking of ideas to determine priorities and future plans.
