3.1. Step 1: Familiarisation with Transcripts
3.2. Step 2: Qualitative Coding of Transcripts
3.3. Step 3: Construction of Initial Behavioural Systems Map
- (a)

- (c)
- Code mentioned at least two times and in at least two transcripts.
3.4. Step 4: Expert Review (Round 1)
- To what extent does the diagram capture the most relevant and important information?
- Are there parts of the diagram that are too complex or too simple?
- Are there any variables or links missing?
- Are there any variables or links that are not needed?
- Are there any variables or links that seem incorrect?
- Do you have any other feedback points?
