After each nutritional topic had been touched upon, in order to explore her underlying motivations, the respondent was asked why
particular shifts did or did not take place.
Next, the respondent was asked about her nutrition awareness during the previous three months compared to earlier phases in life, she was questioned about why these shifts did or did
not take place. In order to obtain reliable and valid answers,
the interviewer sought confirmation that she had understood correctly by summarising what the participant had said. To establish reproducibility, the interviewer used an interview protocol that contained a standard introduction, purpose and conclusion[17]. To ensure reliability, a part of
the interviews were watched by the second author of this article, through the use of a live video of the interview in another room.
