Focus
Group Research
Overview
Focus
group research is based on facilitating an
organized discussion with a group of individuals
selected because they were believed to be
representative of some class (e.g. consumers of
a product or service category, voters, parents
of school children, etc.).
Discussion
is used to bring out insights and understandings
in ways which simple questionnaire items may not
be able to tap.
Focus
group research has long been prominent in
marketing studies, in part because market
researchers seek to tap emotional and
unconscious motivations not amenable to the
structured questions of conventional survey
research.
The
interaction among focus group participants
brings out differing perspectives through the
language that is used by the respondents.
People
get caught up in the spirit of group discussion
and may reveal more than they would in the more
formal interview setting. As respondents ask
questions of each other, new avenues of
exploration are opened.
In
discussions, multiple meanings are revealed as
different respondents interpret topics of
discussions in different ways.
Interaction
is the key to successful focus groups. In an
interactive setting, respondents draw each other
out, sparking new ideas. The reactions of each
person spark ideas in others, and one person may
fill in a gap left by others. One may even find
a form of collaborative mental work, as
respondents build on each other to come to a
consensus that no one individual would have
articulated on their own.
Focus
group research vs. group interviewing.
In
group interviewing a standard survey instrument
(questionnaire) is administered to respondents
simultaneously.
In
focus group studies, in contrast, there is no
standard instrument, only a topic to be explored
through the exchange of group discussion.
For
instance, a start-up topic question might be,
"What are the present satisfactions and
dissatisfactions with X and those of Y?"
The
respondents can have a strong influence on the
subtopics which are examined and the insights
which are yielded.
Where
survey research, even group survey research,
requires a priori theory or at least a list of
subtopics as a guide for selection of items to
be included in the survey instrument, there is
no a priori theory in focus group research.
Focus
groups are a method of choice where the dynamics
which determine outcomes are not well known and
surprises are expected, as in marketing research
where focus groups are brought together to react
to product concepts or candidate advertisements.
Role of
the moderator.
The
role of the focus group moderator is to
facilitate, not dominate discussion.
The
moderator encourages the participation of
everyone and seeks to limit the domination of
discussion by a few respondents.
The
moderator may also give prompting questions
("probes") to elicit expansion on interesting
subtopics, such as "Give us an example of ...,"
"Tell us more about that," "Keep talking," or
"Can someone summarize what we've been saying."
The
moderator will generally not ask closed-ended,
yes-no questions, such as "Do you prefer X?",
instead always using non-directive prompts like
"What is your reaction to X?"
The
moderator may also seek to return conversation
to the topic at hand.
Finally,
the moderator may take notes or record the
conversation of the group, though often that
role is left to an assistant moderator.
The
moderator must record not only overt statements,
but must also be sensitive to omissions, choice
of words. non-verbal communications, expressions
of emotion, energy levels, and the roles played
by the discussant.
Because
of the strong role of the moderator, usually the
same one is used if there are multiple groups,
in an attempt to control for the influence of
the moderator.
Implementation.
A
focus group typically has 6-10 participants in
each group session. However, examples can be
found of both smaller and larger groups. Focus
group facilitators usually regard 10-12
participants as becoming unwieldy and
counterproductive. It becomes difficult to keep
all the participants engaged in the
discussion.
It
is a mistake to do only a single focus group. At
least two groups should always be executed. The
second group will serve to confirm the findings.
The broader and more ambitious the purposes of
doing focus group research, the more groups are
appropriate. A study of "women's attitudes
toward health services" will require many more
groups than one on "consumers' preferences for
detergent," for instance.
Sessions
usually last for approximately two hours. The
sessions are recorded on audio tape to provide a
verbatim transcript for later analysis. On
occasion, video taping of the respondents may
also be appropriate.
Use
of follow-up interviews with participants, can
be very fruitful.
The
number of topics explored per session is usually
at most three (often just one), with subtopics
under each.
Sessions
are usually held in neutral locations such as
formal focus group facilities or hotel meeting
rooms. They should not be conducted in the
workplace for a study involving employees.
Participants
are selected using a "screener" which identifies
the demogrphic, behavioral and lifestyle
characteristics of the potential respondent.
Respondet criteria are discussed
Participants
are informed of the purpose of the focus group
study. They participate on a first-name basis,
which encourages informality and openness while
suggesting greater anonymity.
Ice-breaking
exercises are often used to start a focus group
discussion. One example is the "eyes closed
exercise," in which the moderator asks members
of the focus group to close their eyes, imagine
the last time they were involved with the
subject of the study, and to articulate their
remembrance of this. This sharing of experiences
while eyes are closed is intended to break down
formalities and get conversation rolling as
respondents feel closer as a result of the
sharing experience.
Another
example of an ice-breaking exercise is to have
the respondents draw a cartoon or picture of the
best of worst aspects of X, then share their
work with the group.
A
third example is word association, asking
respondents quickly and without thinking to
finish prompts like "The worst thing about X is
...." or "People who like X tend to be ....".
Participants write their answers on a sheet of
paper, then share them with the group.
Drawbacks
of the focus group method include the
potentially strong influence, one way or the
other, of the discussion moderator; the
difficulty of separating individual viewpoints
from the collective group viewpoint; and the
difficulty of obtaining a representative sample
within a small focus group.
In
a group context, individuals may be less willing
to reveal sensitive information because
assurance of confidentiality is lost, in spite
of the practice of urging participants not to
reveal discussions of the group.
The
focus group method may also have positive or
negative effects on the subjects, particularly
when members of the group are associated in work
or other social contexts.
Assumptions
Focus
groups are not a panacea for tapping "true"
feelings. People often do not themselves
understand their own motivations and preferences
and thus cannot articulate them well. People
have complex, even conflicting motivations,
which may come together in unpredictable ways
given only slightly varying ways of presenting a
stimulus.
People
may give acceptable or politically correct
responses in front of peers, and they may act
differently in real situations compared with
hypothetical ones.
They
may be aware of the study's sponsorship and tell
the researcher what they believe he or she wants
to hear.
People
tend to express views which enhance their own
image of themselves, and they also may formulate
opinions "on the spot," lacking any real
commitment to what they say. And, people lie.
When is
the focus group approach not recommended?
Focus
groups are generally a poor choice when
quantitative information is desired. For
example, when one wants to know the percentage
of people who will buy product X or vote for
candidate X.
The
small size of focus groups makes any estimates
of quantitative proportions unreliable, even if
the members of the focus group are
representative of the target population.
However, when one sees concensus of opinion over
a series of focus groups, while a hard
statistical conclusion cannot be drawn, logic
would suggest that when the majority of
respondents agree on a position, that position
is likely to be reflective of the
marketplace.
Finally,
focus group research is a poor choice for
predicting future action in settings yet to
emerge since focus group respondents will
articulate their views in terms of their own
present experiences.
