The interviewee is the person answering the question, referred to in our documentation as the 'response unit'.
The interviewee may change during the questionnaire.
The interviewee is the subject of the questionnaire. This is often the cohort member, or the cohort member's mother, for example. This should be applied according to the Controlled Vocabulary, see Interviewee (Response Unit). The Interviewee is added when creating a Question Component.
