The interview as a research technique has been a tool to obtain information through a communicative process (Estrada, s.f.), where the questions must be very well planned to obtain the data that is sought.
But after the interview, what’s next?
How do we know that the data shown in an investigation is true? The Health Plus project proposal was to record and interview about the importance of counseling on the well-being of patients.
The recorded interviews were reproduced in a national conference, achieving better dissemination and greater acceptance among people outside the investigation. (Greasley, 2006)
The final result was favorable for the Health Plus project, which motivated the qualitative research to carry out this practice. However, an interview can be harm to the purity of the data; the interviewed may feel intimidated or exposed, and their answers could change.
A proposal to prevent an interviewed from changing his answers is to consider the modifications in the audio and the image so that you remain anonymous and the information can be disseminated with your authorization.
Making recorded interviews helps more people to know the results of an investigation (Estrada, s.f.) and also helps to transform a qualitative research technique.
