Qualitative Research - Conducting an Interview

A Qualitative Interview is a method of collecting rich and detailed information about how individuals experience, understand and explain events in their lives. It is…

                    “…a conversation with a purpose” (Holloway, 1997) 
                    …a relationship between two or more human beings (Randall and Phoenix, 2009) 

Types of questioning
  • Unstructured Interview The interviewer uses at most an 'aide memoir' - notes to jog the memory - rather than a list of questions. The interview may be like a conversation, with the interviewer responding to the interviewee and letting them speak freely. 
  • Semi-structured Interview The interviewer has a list of questions or key points to be covered and works through them in a methodical manner. Similar questions are asked of each interviewee, although supplementary questions can be asked as appropriate. The interviewee can respond how they like and does not have to 'tick a box' with their answer. 
  • Structured Interview The interviewer asks the interviewee a series of specific questions, to which a fixed range of answers are possible ('ticking a box'). This is the typical form of interview used in social survey research, and can provide quantitative data, as in a questionnaire. 
The Interview Guide
  • Drawing on relevant literature (rather than solely personal experience) construct a list of questions that relate to the research topic, they should address the interviewees experience, behaviour, context, values, senses and personal background. Do not expect interviewees to be able to directly address your research question. 
  • Questions should be broad and open-ended, clearly worded, to the point and understandable to the participant. They should be structured so they are “funnelled” from broader “warm-up” questions through to more focussed probing questions. 
  • Make sure you introduce yourself and explain the aim of the interview. Also adhere to academic ethics by making sure the interviewee is fully aware of the purpose of the research 
  • Avoid asking leading questions. 
  • Review, refine, trial and repeat this process several times rather than use the first questions that you develop. 
  • Kvale (1996) has identified nine kinds of question asked in qualitative interviews. There is no prescribed use of these questions but they may help develop the interview guide. 
    • Introducing questions: 'Why did you...?' or 'Can you tell me about...?' 
    • Follow up questions: Questions may include: 'What did you mean...?' or 'Can you give more detail...?' 
    • Probing questions: You can employ direct questioning to follow up what has been said and to get more detail. 'Do you have any examples?' or 'Could you say more about...?' 
    • Specifying questions: Such as 'What happened when you said that?' or 'What did he say next?' 
    • Direct questions: Questions with a yes or no answer are direct questions. You might want to leave these questions until the end so you don't lead the interviewee to answer a certain way. 
    • Indirect questions: You can ask these to get the interviewee's true opinion. 
    • Structuring questions: These move the interview on to the next subject. For example, 'Moving on to...' 
    • Silence: Through pauses you can suggest to the interviewee that you want them to answer the question! 
    • Interpreting questions: 'Do you mean that...?' or 'Is it correct that...?' 

Before the interview
  • Contact your participant at least one day before the interview by phone or email as a courtesy reminder (Sparkes and Smith, 2014). 
  • Practice using the methods of recording. 
  • Choose a comfortable setting for the interview that is free from distractions.
  • Gain consent from your interviewee, highlight that you will be recording the interview.
During the interview
  • Avoid sharing your hypotheses but do explain in broad terms the goals of the research, particularly if you can frame it in terms of solving a problem that is important to the interviewee. 
  • Make sure the interviewee understands the confidentiality of the interview and issues surrounding ethics, data storage and how the information will be used. 
  • Trust and rapport and empathy are important so that participants are more likely to be open in their responses. Be cautious of over-rapport (Sparkes and Smith, 2014) and of projecting your own fears, interests and values on to the participant. 
  • Record the interview (as long as the participant agrees to this) and consider where you will be sat in relation to the recording device. 
  • Do not use emotional, loaded or biased language in either your questioning or any responses. 
  • Be an active listener (body language, attitude, conversational style) and be careful about what your behaviour conveys to participants (e.g., expressions of surprise, jumping to take notes). 
  • Follow-up questions should be used to encourage expansion of ideas deemed most relevant to the research question These probes should be short and simple to avoid breaking the interviewee’s focus 
    • For continuation “Then what happened?”...for elaboration “Can you give me an example?”…for steering the conversation “You mentioned that…” 
    • Probes can be non-verbal as well, such as using silence to encourage elaboration, or leaning forward to indicate interest. Be careful to vary the probes and not to overuse them 
  • When interviewees are comfortable and conversational, you may miss the opportunity for intended follow-up questions. Rather than interrupting, keep notes on follow-up to ensure that you remember to return to them later. 
  • It may be helpful to summarise key ideas and themes back to the interviewee to ensure you have a proper understanding of their meaning. 
After the interview
  • Make field notes as soon as possible 
  • Contact the interviewee and thank them for their time. 
  • As soon as possible after the interview, transcribe it using the recording and your field notes.
