Key Informant Interview: This is a qualitative method in
which a knowledgeable person in study site or
community is contacted and interviewed by the
researcher or data collector. Questions for the interview
session may be prepared in advance, or sometimes only
guiding themes are prepared for the session. This
method is similar with in-depth interview, in that in
most cases one individual person is contacted and
interviewed at a time. However, in the latter, the
researcher/ interviewer digs deep into issues (Macionis,
1997).
Focus Group Discussion: This is a form of qualitative
data collection method in which intends to make use of
the explicit interaction dynamic among group members
which may yield important information on certain topic.
This qualitative method of data collection has become
so popular particularly in the recent decades; it is highly
being used by researchers from crosscutting fields such
as public health, anthropology, and other behavioral
sciences disciplines.
