  • rapport and empathy - encourages a good rapport between interviewer and respondent - makes respondent feel at ease - allows interviewer to show sympathy
  • empowerment for respondents - neutralises the hierarchy, feel more on an equal footing
  • practical advantages - relatively quick method for gathering in depth data


  • lack of reliablity - each interview is unique
  • difficult to repeat - might be a different interviewer - might not get the same relationship
  • interview bias - values of the researcher could interfere with the results
  • lack representativeness - difficult to get a large enough sample to represent a large population
  • practical - takes time - need to be taped and transcribed
