Learning Objectives
By the end of this presentation you will be able to:
1. Define what a researchable question is.
2. Describe the necessary steps to take to determine whether a topic is relevant, researchable, and significant.
3. Understand and know how to use common tools in the profession that can assist a researcher in framing a precise and specific research question.
What is a “Researchable Question?”
• An explicit query about a problem that can be challenged,
examined, and analyzed.
• Goal is to produce new or useful information that targets
an important clinical problem about patient care that may be
personally encountered in clinical practice or is of concern by
any PT or health-care practitioner, or the community.
Where do I begin?
First Step: Is the information I want to know matter to the rest
of the profession… will it impact or make significant
contribution to the PT profession?
• A research question should be specific and narrow enough to
answer it, yet broad enough to be meaningful to the profession.
A good Research question:• Details the problem statement
• Further describes & refines problem under study
• Adds focus to the problem statement
• Guides data collection and analysis
• Sets/guides the context of a research design.
Formulating a Research Question & Goals
• Research is only as good as the research question
and plan on which the research question is based.
• Study findings should bridge the gap between what is
“already known” and “what needs to be known”.
• What discrepancies/inconsistencies regarding PT
practice need to be resolved or will improve patient
care?
Characteristics of well-written, clinically necessary research questions
• Importance – how important is the question you’re asking? Will it
make a difference to the PT profession or improve patient care?
• Extremely specific – want to explicitly and precisely identify the
variables and population of interest.
• Feasibility - can variables be measured (financially/ethically) in a
realistic time-frame? Must have necessary means to measure them.
• Contextuality – how well does the question fit into the framework of
prior knowledge or evidence? Want to avoid “reinventing the wheel”,
but can explore a different aspect related to a similar concept.
• Interesting: Researcher should be passionate about the topic! Want
to also engage the interest and attention of reviewers, PT colleagues
& community!
To Prepare for the Task….. A Literature Review is Necessary!
• A review of previous research is necessary to identify where gaps in knowledge
exist. Can also inform you on methods or data collection processes used and what
potential limitations, objections, or shortcomings occurred.
• This is an iterative process. In early phases of research, it is common that the study
design or the research question is changed.
• Want to pose “Background” and “Foreground” Questions(discussed later)
• Read a few general reviews that identify unanswered problems. Return to the
literature after defining your research question & proposed study design.
• Perusing the literature in depth is needed (but a formal systematic review is not
done until a clear research question is developed – to be discussed later).
Additional Processes www.clinicalevidence.com
Here’s a “basic” 5-step clinical questioning process for conducting a
literature review and finding the best available evidence: 2
1. Formulate a feasible Clinical Question
2. Search for answers (Literature Review)
3. Appraise the evidence (Literature Review)
4. Compare results of previous studies to your proposed research question and identify “gaps in knowledge”.
5. Reformulate your clinical question to address new, necessary knowledge and reapply the steps.
(It’s suggested that “SYSTEMS” be a resource starting point (e.g. a Diagnosis, such as obesity), followed by a summary of high-quality systematic reviews/meta-analyses, then individual studies.
How can researchers ensure that their question addresses all critical aspects of what is being investigated?
• A major and important way to formulate the optimal question format is to conduct a literature review.
• To understand an area of research that you are potentially interested in you may want to develop the following:
Clinical “Background” Questions: provides “THE BIG PICTURE”
Clinical “Foreground” Questions: provide “SPECIFIC” &“PRECISE” information about specific clinical situations.
Clinical Background Questions8
General preliminary questions that provide the “big picture”. Can use
the “7 W’s” for framing Background questions:
Example: “What is sleep hygiene and how does it affect physical
health in adolescents?”
• Who
• What
• for Whom
• Why
• Where
• When
• how Well.
Clinical Foreground Questions
A more focused, specific, complex question that provides
precise Information about a specific clinical situation.
Example: “What is the relationship between the quantity and quality of sleep and obesity in adolescents?”
Specific frameworks can help develop a foreground question, using the following mnemonics:
PICO or PICOM
FINER or FINERMAPS
PICO or PICOM7
Useful for clinical therapeutic research, particularly RCT’s and
pragmatic research; questions about therapeutic interventions
that are highly specific.
P = Patient/Problem
I = Intervention
C = Comparison (some resources call this the “Control”) when a new therapy is compared with an existing one.
O = Outcome – the effect of the intervention (outcome)
M = Methodology
Facts about the Process
• After determining a foreground question, a PICO approach can be followed.
• Dissecting the question into parts makes it easy and searchable.
• Several relevant categories of questions can be asked concerning:
PT Treatment or Therapy
Prevention
Diagnosis
Prognosis
Etiology
• Information obtained from the PICO approach can assist in formulating and developing a researchable question. MORE INFO COMING!!!
Examples of using PICO:
P: In patients with knee OA
I: is hydrotherapy more effective (TREATMENT or THERAPY)
C: than traditional PT
O: in relieving joint pain?
P: For obese children
I: do community recreational activities (PREVENTION)
C: compared to educational programs on lifestyle changes
O: reduce the risk of diabetes mellitus?
More Examples:
P: For DVT
I: is D-dimer testing or (DIAGNOSIS)
C: Ultrasound
O: more accurate for diagnosis?
P: In healthy older women that suffer hip fractures
I: within one year after injury (PROGNOSIS)
C: none
O: what is the relative risk of death?
P: Do adults
I: who binge drink (ETIOLOGY)
C: compared to those who do not binge drink
O: have higher mortality rates?
Sorting out the Question Type and PICO Parameters
You can plug in information from your own clinical
question and area of interest to study….
THERAPY: In____________, what is the effect of ___________on __________ compared with _______? PREVENTION: For ______, does the use of _______reduce the future risk of ____ compared with ____? DIAGNOSIS OR DIAGNOSTIC TEST: Is _____ more accurate in diagnosing ______compared with _____? PROGNOSIS: Does ________ influence ______________ in patients who have ______________? ETIOLOGY: Are _______ who have_______ at_________ risk for/of _____ compared with/without____? MEANING: How do ____________ diagnosed with ____________ perceive _______________?
FINER or FINERMAPS4
F = Feasible: Do you have access to the target population, equipment, tools, statistical
know-how, Internal/external support (e.g. OPTA grant), other resources? A pilot study can test
procedures & determine if you really want to do the study or can fine-tune protocol. Do you
have enough time to do the study ? Ask ethical board if pilot study approval is needed.
I = is the study Interesting?
N = are the ideas Novel?
E = can study be performed Ethically?
R = how Relevant is the research question: does it provide new or novel information?
Requires a lit review to determine gaps/discrepancies. Is it possible to answer those questions?
M = how Manageable is it to carry out the study?
A = is the information Appropriate?
P = Potential value & Publishability If goal is to publish/present findings, it’s important to
know the research rigor needed (qualitative vs. quantitative methods are very different from
each other). Need to establish research design/methods early on for power and validity.
S = is the research design and study implementation Systematic?
Types of Research Questions7
• The type of specific and answerable research question asked
has critical implications for the study Methods. The study design
must match the type of research question! Types include:
• Descriptive “What impact do PPExams have on MS injury prevention in
female high school athletes?” Has to do with prevalence, incidence.
• Predictive (pragmatic research evaluates interventions or diagnostic
procedures that may impact future actions regarding patient care).
“How well does quadriceps muscle strength predict the likelihood of
developing knee OA after age 65?”
• Causal – Randomized Controlled Trials (RTC’s), longitudinal studies, etc.
A study of treatment effectiveness. “Is functional dry needling more
effective for treating chronic low back pain than cupping?
Logistics of a Research Question
Simple Research questions have 2 basic components: 1 stem, 1 topic.
Example: “What are the concerns of patients following organ transplant-ation? ” Stem is: “What are,” Topic is: concerns of patients after organ transplantation.
Complex questions have more than 1 stem and topic: “What is the relationship of age and educational level to positive adaptation following organ transplantation?”
• “Pruning” a research question: cutting away anything unnecessary, so only the essence remains. Avoid being too ambitious. Refine the research question into something interesting and feasible.
• Ask yourself: “What will this paper add to the body of existing literature” ? The best approach is to “begin at the end”, that is, to think about the conclusion you hope to support when you publish your research findings.
Quick Summary: How to begin writing your research question
• State the question in your own words
• Write down the Research Question as completely as possible
• Divide your question into concepts.
• Narrow to 2-3 concepts (avoid words that don’t add meaning)
• Specify the population to be studied
• Refer to the topic or intervention to be investigated
• Reflect on the outcome of interest (is it meaningful?)
Other important points while framing a research question
Make reference to a population when a relationship is expected
among a certain type of subjects
RQ’s and Hypotheses should be written as specific as possible.
Stick to what will be studied, not the implications of the study
Name the variables in the order in which they occur and will be
measured.
Avoid the words significant/”prove”
Avoid using two different terms to refer to the same variable.
Potential problems and solutions while formulating a research question
FOOD FOR THOUGHT…good & “not-so-good” examples
More Ideas about Research Questions
• Hypotheses start from previous knowledge and experience.
• When they are challenged by anomalies, clinicians and scientists and researchers seek new explanations.
• Build onto your experiences: engage in informal conversations with experienced colleagues and professionals in the field and outside of the profession.
• Be alert to new ideas! (journal clubs, national meetings, etc. What tests, questions or irregularities strikes your mind, that have defied your expectations?).
• Have a skeptical attitude about prevailing beliefs or unresolved issues.
When in doubt….seek advice!
Novice clinical investigators may be challenged, intimidated or
overwhelmed by the research process, so:
Seek the support of a research mentor:
Can be a local mentor or a well-known researcher in the PT
profession! Usually willing to share their own successes and
failures and pitfalls of conducting research!
If you don’t consider yourself “a writer”(or a statistician!)?….inquire about recruiting willing colleagues in or outside of the PT profession. For
writing skills, ask if the ideas you want to convey in your research
question, abstract or article are clear & easy to understand. Practice
will make perfect! Other alternatives are to hire or consider research
collaborators to assist you in your project! It can be collaborative & fun!
Take Home Messages
• A researchable question is simple and well-defined, as well as
specific, and relevant (will the findings makes a difference to your
colleagues, profession and/or community?)
• A researchable question explores gaps in knowledge that exist in
current evidence.
• Well-defined researchable questions need to be matched to the
right study design.
• A research project should be ethical and financially feasible and
of interest to the researcher conducting the study!
