I am doing some research in a psychiatric service interviewing people about their delusions. I have a specific question in mind (are delusions beliefs?) and am getting a lot of qualitative data that could speak to that question (I have a bunch of prompts that I have designed to investigate whether these delusions behave in a way that one would expect if they were indeed beliefs). In addition to some quant data I am gathering, I would love to analyse the verbal responses qualitatively in a more formal way than I initially envisaged. However I don't have experience with Qual methodology. Can any qualitative people advise how you would analyse verbal responses that are given to specific prompts? I am not really looking for phenomenological themes or what-it's-likeness, I am more wanting to examine answers people give and see whether they do or do not indicate certain characteristics.
Any readings or methodological suggestions would be welcome!
