The overall vulnerability can be increased by the inadequate consideration of issues related to privacy and confidentiality. Some possible harm that can be caused to the interviewee includes the following : Violation of privacy of participants by the accessibility of files or records with private details without the consent of interviewee 。
Secret observation of participant in terms of their behaviour
Failure in respecting cultural values and traditions.
While these are desirable for knowing the rules of confidentiality and privacy prior to agreement among the interview, the issue of privacy suggests that no entire assurance is provided. Therefore, some of the researchers have recommended a model of process consent or continuous consent where consent is reaffirmed in the entire research process .
As interviews can end up involving a dual end of therapy and information, and hence, a dual role is played by the research. The researcher should ensure the protection of participants from experience any harm. In a more ambiguous way, the research will show willingness in obtaining material of good quality. In order to ensure maximum effective, specific approaches of counselling can be used for drawing upon the key participants.
