You have to annex a description of the research procedures for distinct methods of data collection involved in your research (e.g., a description of the interview procedure and description of your focus groups procedure). We are looking to see that your research procedure maps well onto the proposed methods of data collection, particularly those involving human participants, that these are legitimate in the light of your research aims, are appropriate in the context of the research design, and have been chosen after systematic exclusion of other methods of data collection (eg secondary data analysis).
Survey questionnaires, interview schedule, group discussion or observation schedules all constitute research instruments. You are required to attach a detailed description of each of the procedures of your research (e.g., if the research involves a questionnaire, explain the rational for the use of the sampling procedure in the form proper). If a mixed-methods design is used, the information sheets usually offer information on procedures of data collection on each of these separately.
You have to annex separate lists of questions you intend to ask of your research subjects. (e.g., a list of interview questions, if your research involves interviews). If at the time of submitting your application for ethical approval you do not have the final version of questions (e.g., you may not have the final version of the interview schedule, or phrasing of interview questions), you have to provide at least a good sketch of the procedure (e.g., of the types of questions that will be used in the interview).
There may be components of your methodology that don’t need ethical approval (e.g., interpretative analysis of publically available information, access to and referencing freely accessible sources, meetings with individuals to assess the background information for your research aims). You don’t need to annex a description of these components.
