• The researcher can control the sequence of questions and can also ask probing
questions.
The disadvantages are:
• They are very costly.
• Length of the interview is limited.
• Participants without telephones are excluded.
• The time of the call may be inconvenient for the interviewee.
• Open-ended questions are difficult to use.
• The researcher cannot assess the surroundings of the interviewee.
The role of the interviewer
• The interviewer’s role is difficult. As a specialist of the study, you need to get answers
to your questions and build rapport with the respondent, yet remaining neutral and
objective.
• You encroach on the respondent’s time and privacy and your research may not benefit
the respondent
– so you need to be considerate and polite all the time.
• The respondent may be uncomfortable, afraid, embarrassed and suspicious of you
and the questions
– again, you need to be considerate and polite all the time.
• You need to help the participant feel that they can give any truthful answer.
• You may not reveal
your opinion, verbally or nonverbally.
• Treat the participant’s answers in a matter-of-fact manner and retain ethical standards.
• The respondent may deviate from the question and you need to re-direct the response
to the question.
• You need to define the situation, ensure that respondents have the information, and
understand it.
• Ensure motivation and cooperation so that the respondent seriously considers your
questions.
