Step’by-step guide to critiquing
research. Part 1: quantitative research
Michaei Coughian, Patricia Cronin, Frances Ryan
Abstract
When caring for patients it is essential that nurses are using the
current best practice. To determine what this is, nurses must be able
to read research critically. But for many qualified and student nurses
the terminology used in research can be difficult to understand
thus making critical reading even more daunting. It is imperative
in nursing that care has its foundations in sound research and it is
essential that all nurses have the ability to critically appraise research
to identify what is best practice. This article is a step-by step-approach
to critiquing quantitative research to help nurses demystify the
process and decode the terminology.

]or many qualified nurses and nursing students
research is research, and it is often quite difficult
to grasp what others are referring to when they
discuss the limitations and or strengths within
a research study. Research texts and journals refer to
critiquing the literature, critical analysis, reviewing the
literature, evaluation and appraisal of the literature which
are in essence the same thing (Bassett and Bassett, 2003).
Terminology in research can be confusing for the novice
research reader where a term like ‘random’ refers to an
organized manner of selecting items or participants, and the
word ‘significance’ is applied to a degree of chance. Thus
the aim of this article is to take a step-by-step approach to
critiquing research in an attempt to help nurses demystify
the process and decode the terminology.
When caring for patients it is essential that nurses are
using the current best practice. To determine what this is
nurses must be able to read research. The adage ‘All that
glitters is not gold’ is also true in research. Not all research
is of the same quality or of a high standard and therefore
nurses should not simply take research at face value simply
because it has been published (Cullum and Droogan, 1999;
Rolit and Beck, 2006). Critiquing is a systematic method of

appraising the strengths and limitations of a piece of research
in order to determine its credibility and/or its applicability
to practice (Valente, 2003). Seeking only limitations in a
study is criticism and critiquing and criticism are not the
same (Burns and Grove, 1997). A critique is an impersonal
evaluation of the strengths and limitations of the research
being reviewed and should not be seen as a disparagement
of the researchers ability. Neither should it be regarded as
a jousting match between the researcher and the reviewer.
Burns and Grove (1999) call this an ‘intellectual critique’
in that it is not the creator but the creation that is being
evaluated. The reviewer maintains objectivity throughout
the critique. No personal views are expressed by the
reviewer and the strengths and/or limitations of the study
and the imphcations of these are highlighted with reference
to research texts or journals. It is also important to remember
that research works within the realms of probability where
nothing is absolutely certain. It is therefore important to
refer to the apparent strengths, limitations and findings
of a piece of research (Burns and Grove, 1997). The use
of personal pronouns is also avoided in order that an
appearance of objectivity can be maintained.
Credibility and integrity
There are numerous tools available to help both novice and
advanced reviewers to critique research studies (Tanner,
2003). These tools generally ask questions that can help the
reviewer to determine the degree to which the steps in the
research process were followed. However, some steps are
more important than others and very few tools acknowledge
this. Ryan-Wenger (1992) suggests that questions in a
critiquing tool can be subdivided in those that are useful
for getting a feel for the study being presented which she
calls ‘credibility variables’ and those that are essential for
evaluating the research process called ‘integrity variables’.
Credibility variables concentrate on how believable the
work appears and focus on the researcher’s qualifications and
ability to undertake and accurately present the study. The
answers to these questions are important when critiquing
a piece of research as they can offer the reader an insight
into \vhat to expect in the remainder of the study.
However, the reader should be aware that identified strengths
and limitations within this section will not necessarily
correspond with what will be found in the rest of the work.
Integrity questions, on the other hand, are interested in the
robustness of the research method, seeking to identify how
appropriately and accurately the researcher followed the
steps in the research process. The answers to these questions

Critiquing the research steps
In critiquing the steps in the research process a number
of questions need to be asked. However, these questions
are seeking more than a simple ‘yes’ or ‘no’ answer. The
questions are posed to stimulate the reviewer to consider
the implications of what the researcher has done. Does the
way a step has been applied appear to add to the strength
of the study or does it appear as a possible limitation to
implementation of the study’s findings? {Table 1).
Eiements influencing beiievabiiity of the study
Writing style
Research reports should be well written, grammatically
correct, concise and well organized.The use ofjargon should
be avoided where possible. The style should be such that it
attracts the reader to read on (Polit and Beck, 2006).
Hritislijourn.il of Nursing. 2007. Vol 16. No 11
Author(s)
The author(s’) qualifications and job title can be a useful
indicator into the researcher(s’) knowledge of the area
under investigation and ability to ask the appropriate
questions (Conkin Dale, 2005). Conversely a research
study should be evaluated on its own merits and not
assumed to be valid and reliable simply based on the
author(s’) qualifications.
Report title
The title should be between 10 and 15 words long and
should clearly identify for the reader the purpose of the
study (Connell Meehan, 1999). Titles that are too long or
too short can be confusing or misleading (Parahoo, 2006).

the main findings and conclusions and recommendations
(Conkin Dale, 2005). From the abstract the reader should
be able to determine if the study is of interest and whether
or not to continue reading (Parahoo, 2006).
Eiements influencing robustness
Purpose of the study/research problem
A research problem is often first presented to the reader in
the introduction to the study (Bassett and Bassett, 2003).
Depending on what is to be investigated some authors will
refer to it as the purpose of the study. In either case the
statement should at least broadly indicate to the reader what
is to be studied (Polit and Beck, 2006). Broad problems are
often multi-faceted and will need to become narrower and
more focused before they can be researched. In this the
literature review can play a major role (Parahoo, 2006).
Logical consistency
A research study needs to follow the steps in the process in a
logical manner.There should also be a clear link between the
steps beginning with the purpose of the study and following
through the literature review, the theoretical framework, the
research question, the methodology section, the data analysis,
and the findings (Ryan-Wenger, 1992).
Literature review
The primary purpose of the literature review is to define
or develop the research question while also identifying
an appropriate method of data collection (Burns and
Grove, 1997). It should also help to identify any gaps in
the literature relating to the problem and to suggest how
those gaps might be filled. The literature review should
demonstrate an appropriate depth and breadth of reading
around the topic in question. The majority of studies
included should be of recent origin and ideally less than
five years old. However, there may be exceptions to this,
for example, in areas where there is a lack of research, or a
seminal or all-important piece of work that is still relevant to
current practice. It is important also that the review should
include some historical as well as contemporary material
in order to put the subject being studied into context. The
depth of coverage will depend on the nature of the subject,
for example, for a subject with a vast range of literature then
the review will need to concentrate on a very specific area
(Carnwell, 1997). Another important consideration is the
type and source of hterature presented. Primary empirical
data from the original source is more favourable than a
secondary source or anecdotal information where the
author relies on personal evidence or opinion that is not
founded on research.
A good review usually begins with an introduction which
identifies the key words used to conduct the search and
information about which databases were used. The themes
that emerged from the literature should then be presented
and discussed (Carnwell, 1997). In presenting previous
work it is important that the data is reviewed critically,
highlighting both the strengths and limitations of the study.
It should also be compared and contrasted with the findings
of other studies (Burns and Grove, 1997).
660
Theoretical framework
Following the identification of the research problem
and the review of the literature the researcher should
present the theoretical framework (Bassett and Bassett,
2003). Theoretical frameworks are a concept that novice
and experienced researchers find confusing. It is initially
important to note that not all research studies use a defined
theoretical framework (Robson, 2002). A theoretical
framework can be a conceptual model that is used as a
guide for the study (Conkin Dale, 2005) or themes from
the literature that are conceptually mapped and used to set
boundaries for the research (Miles and Huberman, 1994).
A sound framework also identifies the various concepts
being studied and the relationship between those concepts
(Burns and Grove, 1997). Such relationships should have
been identified in the literature. The research study should
then build on this theory through empirical observation.
Some theoretical frameworks may include a hypothesis.
Theoretical frameworks tend to be better developed in
experimental and quasi-experimental studies and often
poorly developed or non-existent in descriptive studies
(Burns and Grove, 1999).The theoretical framework should
be clearly identified and explained to the reader.
Aims and objectives/research question/
research hypothesis
The purpose of the aims and objectives of a study, the research
question and the research hypothesis is to form a link between
the initially stated purpose of the study or research problem
and how the study will be undertaken (Burns and Grove,
1999). They should be clearly stated and be congruent with
the data presented in the literature review. The use of these
items is dependent on the type of research being performed.
Some descriptive studies may not identify any of these items
but simply refer to the purpose of the study or the research
problem, others will include either aims and objectives or
research questions (Burns and Grove, 1999). Correlational
designs, study the relationships that exist between two or
more variables and accordingly use either a research question
or hypothesis. Experimental and quasi-experimental studies
should clearly state a hypothesis identifying the variables to
be manipulated, the population that is being studied and the
predicted outcome (Burns and Grove, 1999).
Sample and sample size
The degree to which a sample reflects the population it
was drawn from is known as representativeness and in
quantitative research this is a decisive factor in determining
the adequacy of a study (Polit and Beck, 2006). In order
to select a sample that is likely to be representative and
thus identify findings that are probably generalizable to
the target population a probability sample should be used
(Parahoo, 2006). The size of the sample is also important in
quantitative research as small samples are at risk of being
overly representative of small subgroups within the target
population. For example, if, in a sample of general nurses, it
was noticed that 40% of the respondents were males, then
males would appear to be over represented in the sample,
thereby creating a sampling error. The risk of sampling
Britishjournal of Nursing. 2007. Vol 16. No II
RESEARCH METHODOLOGIES
errors decrease as larger sample sizes are used (Burns and
Grove, 1997). In selecting the sample the researcher should
clearly identify who the target population are and what
criteria were used to include or exclude participants. It
should also be evident how the sample was selected and
how many were invited to participate (Russell, 2005).
Ethical considerations
Beauchamp and Childress (2001) identify four fundamental
moral principles: autonomy, non-maleficence, beneficence
and justice. Autonomy infers that an individual has the right
to freely decide to participate in a research study without
fear of coercion and with a full knowledge of what is being
investigated. Non-maleficence imphes an intention of not
harming and preventing harm occurring to participants
both of a physical and psychological nature (Parahoo,
2006). Beneficence is interpreted as the research benefiting
the participant and society as a whole (Beauchamp and
Childress, 2001). Justice is concerned with all participants
being treated as equals and no one group of individuals
receiving preferential treatment because, for example, of
their position in society (Parahoo, 2006). Beauchamp and
Childress (2001) also identify four moral rules that are both
closely connected to each other and with the principle of
autonomy. They are veracity (truthfulness), fidelity (loyalty
and trust), confidentiality and privacy.The latter pair are often
linked and imply that the researcher has a duty to respect the
confidentiality and/or the anonymity of participants and
non-participating subjects.
Ethical committees or institutional review boards have to
give approval before research can be undertaken. Their role
is to determine that ethical principles are being applied and
that the rights of the individual are being adhered to (Burns
and Grove, 1999).
Operational definitions
In a research study the researcher needs to ensure that
the reader understands what is meant by the terms and
concepts that are used in the research. To ensure this any
concepts or terms referred to should be clearly defined
(Parahoo, 2006).
Methodology: research design
Methodology refers to the nuts and bolts of how a
research study is undertaken. There are a number of
important elements that need to be referred to here and
the first of these is the research design. There are several
types of quantitative studies that can be structured under
the headings of true experimental, quasi-experimental
and non-experimental designs (Robson, 2002) {Table 2).
Although it is outside the remit of this article, within each
of these categories there are a range of designs that will
impact on how the data collection and data analysis phases
of the study are undertaken. However, Robson (2002)
states these designs are similar in many respects as most
are concerned with patterns of group behaviour, averages,
tendencies and properties.
Methodology: data collection
The next element to consider after the research design
is the data collection method. In a quantitative study any
number of strategies can be adopted when collecting data
and these can include interviews, questionnaires, attitude
scales or observational tools. Questionnaires are the most
commonly used data gathering instruments and consist
mainly of closed questions with a choice of fixed answers.
Postal questionnaires are administered via the mail and have
the value of perceived anonymity. Questionnaires can also be
administered in face-to-face interviews or in some instances
over the telephone (Polit and Beck, 2006).
Methodology: instrument design
After identifying the appropriate data gathering method
the next step that needs to be considered is the design
of the instrument. Researchers have the choice of using
a previously designed instrument or developing one for
the study and this choice should be clearly declared for
the reader. Designing an instrument is a protracted and
sometimes difficult process (Burns and Grove, 1997) but the
overall aim is that the final questions will be clearly linked
to the research questions and will elicit accurate information
and will help achieve the goals of the research.This, however,
needs to be demonstrated by the researcher.

If a previously designed instrument is selected the researcher
should clearly establish that chosen instrument is the most
appropriate.This is achieved by outlining how the instrument
has measured the concepts under study. Previously designed
instruments are often in the form of standardized tests
or scales that have been developed for the purpose of
measuring a range of views, perceptions, attitudes, opinions
or even abilities. There are a multitude of tests and scales
available, therefore the researcher is expected to provide the
appropriate evidence in relation to the validity and reliability
of the instrument (Polit and Beck, 2006).
Methodology: validity and reliability
One of the most important features of any instrument is
that it measures the concept being studied in an unwavering
and consistent way. These are addressed under the broad
headings of validity and reliability respectively. In general,
validity is described as the ability of the instrument to
measure what it is supposed to measure and reliability the
instrument’s ability to consistently and accurately measure
the concept under study (Wood et al, 2006). For the most
part, if a well established ‘off the shelf instrument has been
used and not adapted in any way, the validity and reliability
will have been determined already and the researcher
should outline what this is. However, if the instrument
has been adapted in any way or is being used for a new
population then previous validity and reliability will not
apply. In these circumstances the researcher should indicate
how the reliability and validity of the adapted instrument
was established (Polit and Beck, 2006).
To establish if the chosen instrument is clear and
unambiguous and to ensure that the proposed study has
been conceptually well planned a mini-version of the main
study, referred to as a pilot study, should be undertaken before
the main study. Samples used in the pilot study are generally
omitted from the main study. Following the pilot study the
researcher may adjust definitions, alter the research question,
address changes to the measuring instrument or even alter
the sampling strategy.
Having described the research design, the researcher should
outline in clear, logical steps the process by which the data
was collected. All steps should be fully described and easy to
follow (Russell, 2005).
Analysis and results
Data analysis in quantitative research studies is often seen
as a daunting process. Much of this is associated with
apparently complex language and the notion of statistical
tests. The researcher should clearly identify what statistical
tests were undertaken, why these tests were used and
what •were the results. A rule of thumb is that studies that
are descriptive in design only use descriptive statistics,
correlational studies, quasi-experimental and experimental
studies use inferential statistics. The latter is subdivided
into tests to measure relationships and differences between
variables (Clegg, 1990).
Inferential statistical tests are used to identify if a
relationship or difference between variables is statistically
significant. Statistical significance helps the researcher to
662
rule out one important threat to validity and that is that the
result could be due to chance rather than to real differences
in the population. Quantitative studies usually identify the
lowest level of significance as PsO.O5 (P = probability)
(Clegg, 1990).
To enhance readability researchers frequently present
their findings and data analysis section under the headings
of the research questions (Russell, 2005). This can help the
reviewer determine if the results that are presented clearly
answer the research questions. Tables, charts and graphs may
be used to summarize the results and should be accurate,
clearly identified and enhance the presentation of results
(Russell, 2005).
The percentage of the sample who participated in
the study is an important element in considering the
generalizability of the results. At least fifty percent of the
sample is needed to participate if a response bias is to be
avoided (Polit and Beck, 2006).
Discussion/conclusion/recommendations
The discussion of the findings should Oow logically from the
data and should be related back to the literature review thus
placing the study in context (Russell, 2002). If the hypothesis
was deemed to have been supported by the findings,
the researcher should develop this in the discussion. If a
theoretical or conceptual framework was used in the study
then the relationship with the findings should be explored.
Any interpretations or inferences drawn should be clearly
identified as such and consistent with the results.
The significance of the findings should be stated but
these should be considered within the overall strengths
and limitations of the study (Polit and Beck, 2006). In this
section some consideration should be given to whether
or not the findings of the study were generalizable, also
referred to as external validity. Not all studies make a claim
to generalizability but the researcher should have undertaken
an assessment of the key factors in the design, sampling and
analysis of the study to support any such claim.
Finally the researcher should have explored the clinical
significance and relevance of the study. Applying findings
in practice should be suggested with caution and will
obviously depend on the nature and purpose of the study.
In addition, the researcher should make relevant and
meaningful suggestions for future research in the area
(Connell Meehan, 1999).
References
The research study should conclude with an accurate list
of all the books; journal articles, reports and other media
that were referred to in the work (Polit and Beck, 2006).
The referenced material is also a useful source of further
information on the subject being studied.
Conciusions
The process of critiquing involves an in-depth examination
of each stage of the research process. It is not a criticism but
rather an impersonal scrutiny of a piece of work using a
balanced and objective approach, the purpose of which is to
highlight both strengths and weaknesses, in order to identify
Uritish Journal of Nursinii. 2007. Vol 16. No II
RESEARCH METHODOLOGIES
whether a piece of research is trustworthy and unbiased. As
nursing practice is becoming increasingly more evidenced
based, it is important that care has its foundations in sound
research. It is therefore important that all nurses have the
ability to critically appraise research in order to identify what
is best practice.
