Phase I: step III

In the third step, the domains and items of the respective instrument, which are extracted through using a systematic review, FGDs and interviews with the target group, will be examined by the research team in terms of overlapping and duplication. Then, in order to determine the ultimate domains and items, the table of specifications methodology will be used.³⁴ A panel of people with expertise in the fields of emergency medicine will review the items in each domain. In practice, alignment of a category of items, which will be placed in the rows, with the constituting domains, which will be placed in the columns, will be considered. Next, the evidence will be quantitatively, based on the percentage of the specialists’ consensus on the rows and columns of the table of specifications, and qualitatively, based on the specialists’ feedback on what other items are added, compiled and analysed by the panel of experts. Finally, alpha version of the instrument will be designed.
