On
researcher as instrument in qualitative research: for Housing Studies students
Highlight 6 ideas of researcher as instrument in
qualitative research, notably in doing part-time 4-month Housing Studies
dissertation projects.
In qualitative
research, the researcher is the primary instrument: you do not merely
administer a fixed questionnaire; you actively notice context, build rapport,
ask follow-up questions, interpret meaning, and make justified methodological
decisions. For a part-time, four-month Housing Studies dissertation, this role
is a strength if it is made transparent and disciplined—not treated as a source
of “bias” that can simply be removed.
Six core ideas
1. You are an adaptive meaning-maker
Unlike a
standardised survey instrument, you can respond to what participants actually
say. During a tenant or resident interview, you may ask, “Could you give an
example?”, “What changed after that?”, or “What do you mean by ‘unaffordable’?”
This flexibility helps uncover meanings, experiences, and mechanisms that a
pre-set instrument may miss.
For a short
dissertation, prepare a semi-structured interview guide with a small number of
core topics, but use probing questions selectively. Do not change the central
research question midstream; adapt only to deepen relevant evidence.
Housing
illustration: If an interviewee
says that their flat is “too small,” the issue may concern physical floor area,
overcrowding, lack of privacy, inability to work from home, family conflict, or
inadequate storage. The researcher-as-instrument identifies which meaning is
relevant and explores it.
2. Your positionality affects access and
interpretation
Your personal and
social position—including your age, language, housing experience, professional
role, educational status, assumptions, and relationship to Hong Kong’s housing
system—can affect:
- Which problem you see as
worth studying
- Who agrees to speak with you
- What participants feel
comfortable telling you
- How you interpret their accounts
- Which findings you
foreground in the dissertation
This is positionality.
It is not a personal autobiography or a confession of bias. It is a concise
account of where you stand in relation to the topic and participants, and of
the possible consequences for the research. Researcher position can shift too:
you may be perceived as an insider by some participants, and as an outsider by
others.
For example, if
you study private-rental affordability while you are a university-educated Hong
Kong resident and not currently affected by insecure housing, participants may
perceive you as an outsider. That may limit disclosure, but it can also help
you avoid assuming that you already understand their experience.
3. Reflexivity is a continuous research
practice
Reflexivity means deliberately examining how your own
assumptions, emotions, reactions, values, and decisions shape the study. It
occurs throughout design, fieldwork, coding, interpretation, and writing—not
only in one “limitations” paragraph at the end. Its purpose is to make your
influence visible and manageable, rather than pretending it does not exist.
Use a short
reflexive journal after each interview. Record:
- Your immediate response:
What surprised, irritated, persuaded, or concerned you?
- Your assumptions: What did
you expect before the interview?
- The interaction: Did your
questions lead the participant in a particular direction?
- Your role: Did the
participant view you as a student, researcher, housing expert, potential helper,
or authority figure?
- Analytic implications: Which
emerging interpretation is supported, challenged, or made uncertain?
- Actions: What, if anything,
should change in the next interview?
A useful
discipline is to separate what was said or observed from your
interpretation of it. This helps prevent early impressions from becoming
unexamined conclusions.
4. Rapport and power require ethical
judgement
As the instrument,
you create the interview atmosphere. Your listening, tone, wording, silence,
empathy, and handling of sensitive disclosures affect data quality. Strong
rapport may help participants explain difficult experiences of overcrowding,
eviction risk, poor living conditions, or financial strain. But rapport must
never turn into pressure to disclose or an implied promise that the research
will solve their housing problem.
Housing research
can involve participants in vulnerable situations, and home-based interviews
may create both participant and researcher safety, emotional, and
confidentiality concerns. Researchers need to make ethical decisions in
practice, not merely obtain initial consent.
For a four-month,
part-time project:
- Use clear plain-language
consent and explain that participation is voluntary.
- Make no promise of
assistance, rehousing, advocacy, or policy change.
- Avoid collecting unnecessary
identifiers, addresses, or landlord details.
- Allow participants to skip
questions, pause, or end the interview.
- Prefer online, telephone, or
neutral public locations where a home visit is unnecessary.
- Have a withdrawal and
safeguarding procedure approved by your university.
5. Your observations and field notes are data
Your interview
recording or transcript is not the whole dataset. As researcher-instrument, you
also capture contextual information: whether an interview was hurried, whether
a participant hesitated before answering, whether other household members were
present, how an online interview was interrupted, and what conditions may have
shaped the account.
Reflective field
notes preserve interview context, the researcher’s observations, methodological
issues, and emerging analytic ideas; they should be completed promptly and
stored securely with the research data.
A compact
post-interview note template can include:

Example for a Housing Studies interview
|
|
Context
|
“Zoom interview,
42 minutes; participant joined from workplace during lunch break.”
|
|
Descriptive
observation
|
“Participant
repeatedly referred to ‘temporary’ living, but had been there for four
years.”
|
|
Reflection
|
“I initially
assumed temporary referred to tenancy length; it may instead mean a sense of
insecurity.”
|
|
Method issue
|
“The question on
rent burden confused gross and net household income; revise wording.”
|
|
Analytic lead
|
“Explore the
difference between legal tenancy security and perceived housing security.”
|
Keep these notes
distinct from the transcript. They supplement participants’ accounts; they do
not substitute for them.
6. Credibility comes from transparent checks,
not neutrality
Because you
influence the study, qualitative quality depends on demonstrating a defensible
process. The aim is not to prove that you were perfectly objective, but to show
that your interpretations are grounded in data, that you actively searched for
alternative explanations, and that another reader can understand how you reached
your conclusions.
Common
trustworthiness criteria are credibility, transferability, dependability,
and confirmability. Practical strategies include triangulation, participant
validation or member checking, reflexive practice, peer/supervisor debriefing,
negative-case analysis, and an audit trail.
For a time-limited
Housing Studies dissertation, keep this proportionate:
- Triangulate
modestly: Compare interviews with relevant public
documents, policy papers, tenancy guidance, housing statistics, or
organisational documents—where appropriate to your question.
- Look
for disconfirming cases: If most interviewees say
location is the major housing concern, actively examine accounts where
cost, household composition, landlord relations, or job insecurity matters
more.
- Use
supervisor/peer debriefing: Discuss a sample of coding
and a tentative theme with your supervisor or a peer; record what you
changed or retained.
- Maintain
an audit trail: Keep dated versions of your interview guide,
recruitment decisions, consent process, transcripts, coding framework,
theme-development notes, and analytic decisions.
- Use
limited member checking if feasible: You
might send participants a short summary of their main points or your
provisional themes—not necessarily entire transcripts—and invite
corrections.

For a part-time
dissertation, depth is usually more credible than an over-ambitious sample. A
tightly defined question—for example, how a specific group experiences housing
affordability, space constraints, or tenure insecurity—makes it easier for you
to listen carefully, analyse systematically, and document your interpretive
role convincingly.
Dissertation-ready wording
You could adapt
the following for a methodology chapter:
In this
qualitative study, the researcher served as the primary research instrument,
conducting semi-structured interviews, making contextual field notes, and
interpreting participants’ accounts through thematic analysis. This role
enabled flexible probing of participants’ meanings and experiences of housing;
however, it also meant that the researcher’s social position, prior
assumptions, and interaction with participants could influence data generation
and interpretation. To address this, the study used reflexive journaling after
each interview, a documented coding and decision trail, comparison of interview
accounts with relevant documentary evidence, and discussion of emerging
interpretations with the dissertation supervisor. These procedures sought to
enhance the credibility, dependability, and confirmability of the findings.
The key message
is: you are not a neutral recording device, but a reflective, ethical, and
accountable interpreter of participants’ meaning. In a compact Housing
Studies project, acknowledging that role explicitly can make the design more
credible rather than less credible.
