Main Methods:
- Biography / participant observation
- Qualitative interviews
- Focus groups
- Discourse or conversation analysis
- Collection and qualitative analysis of texts or documents
- Case study (can be quantatitive too!)
Qualitative interviews
Interviews are always the product of a relationship between the interviewer and the interviewee.
‘A purposeful conversation between two or more people, requiring the interviewer to establish rapport and ask concise and unambiguous questions, to which the interviewee is willing to respond and to listen attentively.’ (Saunders, Lewis and Thornill, 2016).
- Interviews provide a depth and richness of response that other forms of methods and techniques cannot provide (exploratory)
- Some people more willing to speak than to conduct surveys
- They help you explain, better understand, and explore research subjects’ opinions, behaviour, experiences, attitudes etc
- Data collection is non-standardised so that questions and procedures may alter and emerge during a research process that is both naturalistic and interactive.

Informal interviews
- Everyday conversations
- Lack of structure and control
- Later records notes from memory
- No shortcut – this is hard work
- People generally comfortable but may not realise you are taking notes
Semi-structured interviews
- Driven by an interview guide….but also gives space for open-ended answers in own words
- Allows for comparison between people and rich in-depth data but also compromises both
- More efficient than unstructured
Unstructured interviews
- A formal interview but controlled by interviewee as long as on topic
- Encourage people to open up and explain or tell stories in own words
- Good for getting very rich data and for understanding things in depth
- Tricky to compare between people
Structured interviews
- All interviews respond to exactly same questions so can compare
- Oral or written
- Often analysed quantitatively or using specific forms of analysis like Social Network Analysis or Cultural Domain Analysis
Interviews – How Many do I Need?
It depends! You will need to consider issues such as:
- Nature of the research
- Aims, objectives, research questions
- Number of distinctive groups (to be compared/analysed)
- Approach: exclusively qualitative versus mixed methods.
- Representative samples may not be your goal. One interview may be enough, but it depends upon the question you are asking.
Make sure your questions are:
- Closed question (useful in structured questionnaires, but not semi-structured)
- Unclear or vague question (indicative of poor focus to research?)
- Complex question (break down into manageable chunks)
Think about potential probes:
- Detail-oriented (to get more detail) e.g. can you tell me a little more about that situation? Could you give me some more detail about that?
- Elaboration (encourage to expand discussion) – why do you think that is, can you expand on that more? Could you give me an example?
- Clarification (i.e. used to clear up interviewer’s uncertainties) – e.g. did I summarise that correctly, you said XXX – am I hearing that correctly?
