A research gap in a public health nursing thesis is a specific, named limitation in the existing published literature — not a general topic that “has not been studied much.” A defensible gap statement names the body of literature it draws on, states plainly what that literature has and has not established, and explains why the missing piece matters for practice or policy in Malaysia.
What Is a Research Gap, Exactly?
A research gap is the specific point where established knowledge stops and your study begins. It is not the same as a general problem statement, and it is not simply “no one has studied this in Malaysia before” — that claim alone is not a gap unless you can also show what has been studied elsewhere and why the Malaysian setting matters differently. A gap can take several forms: a population that existing studies have not covered, an outcome that has not been measured together with a known predictor, a setting where an intervention has not been tested, or a methodological limitation (small samples, cross-sectional designs only, self-report measures only) that leaves a question genuinely unanswered rather than merely under-discussed.
Why Public Health Nursing Theses Often Struggle to State One
Public health nursing sits across two literatures — clinical nursing practice and population-level public health — and many student drafts pull citations from both without showing where the two literatures actually meet or fail to meet. A common first-draft mistake is to summarise five or six studies in a row and then write a single sentence like “however, limited research has been done on this in Malaysia,” without stating exactly which combination of population, setting, and outcome those five or six studies did not test together. Examiners read that sentence as a summary problem, not a gap, because it does not point to anything specific missing from the literature just reviewed.
What a Weak Research Gap Statement Looks Like
Illustrative weak example: “Many studies have looked at hypertension screening, but not much research has been done on this topic in Malaysia.” This fails for three reasons: it does not name which specific population, setting or outcome measure is missing; it treats “not much research in Malaysia” as automatically meaningful, when the real question is whether the specific combination of variables in your study has been tested anywhere, including outside Malaysia; and it gives the reader nothing to evaluate — there is no way to check whether the claim is true.
Five Worked, Illustrative Research Gap Examples
The five examples below are illustrative constructions built to show the four-part structure in the next section — they are not verified claims about the current state of any specific literature, and you must confirm the actual state of the literature in your own field through your own database search before using anything like them in your proposal.
1. Community Hypertension Screening Uptake
Illustrative: Published studies on community-based hypertension screening programmes report attendance rates and screening outcomes, but few report on why working-age adults who are informed about a screening event choose not to attend it — most studies measure who came, not why non-attenders stayed away. A study measuring self-reported barriers among a sampled group of non-attenders would address this specific gap.
2. Postnatal Home-Visit Follow-Up Adherence
Illustrative: Studies on postnatal home-visit programmes commonly report the number of visits completed against the schedule, but fewer studies measure whether mothers who missed a scheduled visit differ systematically (by parity, distance to clinic, or employment status) from mothers who completed the full schedule — a gap relevant to redesigning outreach for a specific district.
3. Occupational Health Nursing in Small Manufacturing Firms
Illustrative: Occupational health nursing research often focuses on large factories with dedicated occupational health units; a gap can exist around how workplace health screening and referral actually function (or do not function) in small and medium manufacturing firms that have no dedicated occupational health nurse on site.
4. School Health Nursing and Adolescent Mental Health Referral
Illustrative: Studies on school health nursing programmes often report physical health screening coverage, but a gap can exist specifically around how school health nurses identify and refer adolescents showing early signs of mental health difficulty, as distinct from the physical screening outcomes usually reported.
5. Elderly Community Care and Caregiver Burden
Illustrative: Caregiver burden among family caregivers of elderly community-dwelling patients is well studied as a general construct, but a gap can exist around whether burden differs between caregivers who do and do not receive a structured home-visit nursing programme, a comparison that a specific literature search may show has not been made in the Malaysian setting.
The Four-Part Structure of a Defensible Gap Statement
| Part | What it does | Example sentence starter |
|---|---|---|
| 1. Establish the literature | Names the specific body of work your gap sits inside | “Studies on [topic] have consistently shown that…” |
| 2. State what is known | Summarises the settled finding, in one or two sentences | “…[specific finding], across [settings/populations studied].” |
| 3. Name what is missing | States the specific population, outcome, or design element not yet tested | “However, none of these studies have examined [specific missing element].” |
| 4. Explain why it matters | Connects the missing piece to a practice, policy, or population consequence | “This matters because [specific consequence for practice/policy in your setting].” |
Each of the five illustrative examples above can be rewritten to make all four parts explicit. Take the hypertension example: “Studies on community hypertension screening have consistently reported attendance and screening yield across various community settings [Part 1–2]. However, few of these studies report on the reasons informed non-attenders chose not to participate [Part 3]. This matters because outreach redesign requires knowing which specific barriers to target, not just which subgroups attend least [Part 4].”
Where a Gap Statement Goes Wrong Even With the Right Structure
Following the four-part structure does not automatically make a gap statement strong if the underlying literature claim is inaccurate. The most common failure at this stage is asserting that something “has not been studied” without having actually searched for it — a claim your supervisor or examiner may test simply by running the same search themselves. Before finalising your gap statement, run your own search in your university’s library database (Scopus, Web of Science, or CINAHL for nursing-specific literature) using the exact population-outcome-setting combination you plan to claim as missing, and read the abstracts of anything that comes up rather than assuming your search terms were exhaustive.
How a Gap Statement Connects to Your Research Objectives
Once the gap is stated using the four-part structure, your first research objective should restate it directly, usually beginning with a verb like “to examine,” “to determine,” or “to describe.” If your gap statement says a specific missing element has not been tested, your first objective should name testing exactly that element — not a broader or narrower version of it. A frequent inconsistency in student drafts is a gap statement about “reasons for non-attendance” followed by an objective about “the effectiveness of a screening programme,” which is a different research question entirely and signals to an examiner that the gap and the objectives were written at different times without being reconciled.
Common Mistakes That Make a Gap Statement Weak
- Claiming “limited research in Malaysia” without naming the specific population, outcome, or design element that is actually missing.
- Basing the gap claim on a search of five or six studies without a documented, repeatable search strategy.
- Stating a gap that is really a restatement of the problem statement, with no reference to specific prior literature at all.
- Writing objectives that do not map back precisely onto the stated gap.
- Presenting an old or narrow literature base as if it were exhaustive, when a broader search would have surfaced studies that already closed the claimed gap.
Frequently Asked Questions
Is “no study has been done in Malaysia” enough to justify a research gap?
No — you also need to show what has been studied elsewhere and explain specifically why the Malaysian setting, population or system would plausibly produce a different result, otherwise the gap reads as a location claim rather than a knowledge claim.
How many studies should I review before I can claim a gap exists?
There is no fixed number; what matters is that your search strategy is documented and repeatable (specific databases, search terms and date range), so an examiner can verify that your claim reflects a genuine search rather than a handful of convenient citations.
Can a research gap be purely methodological, with no new population or setting?
Yes — a gap can be that prior studies used only cross-sectional designs, only self-report measures, or only small convenience samples, and your study proposes a stronger design on the same substantive question.
Should my research gap and my problem statement say the same thing?
No — the problem statement describes the real-world issue and why it matters; the research gap describes specifically what the published literature has not yet established about that issue. They should connect but not repeat each other word for word.
What if my literature search shows the gap I wanted to claim has already been closed?
Narrow or reframe your gap around what that newer study still leaves open — a setting it did not cover, a population it excluded, or a limitation the authors themselves note — rather than keeping a gap claim that a supervisor could disprove with one search.
Do I need a gap statement for a quantitative and a qualitative public health nursing thesis alike?
Yes, though a qualitative thesis may frame the gap around a lack of in-depth understanding of lived experience or process, rather than a missing statistical association, while still following the same four-part structure.
Where in Chapter 1 should the research gap appear?
Typically immediately after the background and problem statement, and immediately before the research objectives, so the logical chain from problem to gap to objective is visible in one continuous read.
Can I use a gap identified in a systematic review rather than finding it myself?
Yes, and citing a recent systematic review’s own stated “future research” section is a strong, verifiable way to support a gap claim, provided you cite that review directly and accurately represent what it says.
How specific does the “missing” part of the gap need to be?
As specific as your first research objective — if you cannot restate the missing element as a single testable objective, the gap statement is not yet specific enough.
