Research methodology workshop 2015
Dr Sushma Sharma
3. This session ---------
By the end of this session, you will be able to:
• Understand what is Research ?
• Identify the components of a research protocol
• Explain the role of each part within the overall
process of protocol development
• Understand the importance of research protocol
• Able to write a research protocol
4. What is Research?
A systematic investigation, involving the
collection of information (data), to solve a
problem or contribute to knowledge about a theory or
practice.
Research is critical in medicine because it
leads to new discoveries and can change
peoples’ lives by improving health and well being.
Research helps to provide scientific
understanding and solves practical problems.
5. Research (cont.)
Relies on methods and principles that will
produce credible and verifiable results.
All research starts with an idea or question
based on personal experiences.
6. Scientific Approach
The most sophisticated method of acquiring
knowledge is by scientific approach.
Combines important features of induction
and deduction together with other methods
to create a system of acquiring knowledge.
Generally more reliable than other methods.
Approach used most often to perform
medical research.
7. Scientific research
is an integrated approach of deduction and induction
Deduction
Hypothesis generation
Testing the hypothesis
Induction
(Inference on hypothesis)
generalization of the results
In sample
population
Universe
known truths

words like “ A study of---”
24. Background
• Briefly sketch the background of the proposal.
• Critically evaluate the existing knowledge
– What is the general situation and how is the
problem developing?
– Will it grow rapidly if unchecked?
– What has been done so far to address the
problem and with what effect?
• Specifically identify the gaps the proposed research is
intended to fill.

25. Significance
• State concisely and clearly the importance of
your study.
• Emphasize on any novelty or innovation
• Convey the significance of your research to
– 1) scientific contribution
– 2) improving in public health
– 3) change in health policies
– 4) change in patient care
– etc.,
26. Study Objectives
State the objectives of the proposal:
Describe concisely and realistically what the
specific research is intended to accomplish
Avoid grandiose designs- Over-ambitious
proposals that aim to do everything
– burdens, determinants, prevention and control
of….
27. • Objective -examples
• To study whether SNP markers are
associated with obesity and hypertension
phenotypes.
To assess the general population
knowledge & attitude towards Organ
donation
To identify the risk factors for Type-II
diabetes
• Hypotheses
Any hypotheses to be tested.
• • Have clear hypotheses
28. Hypothesis and Specific Aims
• List the specific aims one by one concisely
• Not too many aims; 2-4 best
• Be specific, no general and ambiguous statements
• Be realistic, no unachievable aims
• Aims should be logically linked and arranged accordingly; testing your
hypothesis
29. When you divide a section into subsections,
all the pieces should be of the same pie
30. • Hypothesis-example
• We hypothesize that standard care plus new intervention
(additional drug) will be superior to standard care alone in
reducing CVD mortality among patients with preexisting
heart disease.
• We hypothesize that prophylaxis with inhaled
drug A will be superior to oral preparation of
drug B in preventing acute exacerbation of
reactive airway disease.
• We hypothesize that low birth weight is an
independent risk factor for type II diabetes.

• Allow you to review and critically evaluate the
published literature of your interested topic.
• Develop novel ideas during writing proposal.
• Convince yourself and others that your
research is worth doing.

1. Getting in the Mood
Save multiple copies
of your draft
51. Conclusions
• Developing, and communicating a research protocol is a
