Why write a study protocol?
• Forces researcher to create, define, and refine the research project – Check if the objectives can be achieved
– Check the feasibility of the study
– Prevents failure to collect essential information
– Lays down the rules for all involved
– Required for ethical approval
– Grant applications
– Writing articles

How to write a protocol – basic structure
• Checklist of items to include
1. Title 2. Background 3. Research question – aims & objectives 4. Methods 5. Ethical considerations 6. Project management 7. Timetable 8. Resources 9. References

1. Title
• Ensure title does not promise more than the thesis (or the paper) can deliver – ‘The effect of....on.....’
– ‘ The association between ....and.....’
• Ensure title is succint and avoids redundant phrases
– ‘ A study of...’ – ‘An exploration of…’
• Academic journals
– Running head

Irish Gerontological Society PhD Study Day 2013
2. Background
• Builds case for the proposed study
– Present burden of the problem in quantitative terms – Puts the study in context
– Demonstrate why this research is important
• Suggestion – Write a ‘significance’ paragraph at the end of the background section
– This will help to frame the current status of the work in the field and your study’s potential contribution

3. Research question: aims & objectives
• State overall aim • Objectives link to the hypothesis to be tested
– (primary/ secondary objectives)
• Hypothesis
– Null hypothesis – Alternative hypothesis
• Research question
– PICO/PRO/PER may help to clarify research question

4. Methods
• Study design and setting – What study design will be
used
(Cohort, case-control, cross-sectional, RCT, qualitative)
– What are the strengths and weakness of the particular design?
Division of Population Health Sciences
Irish Gerontological Society PhD Study Day 2013
Standardised reporting of biomedical research
• Guidelines to guide standardised reporting – available for all study designs
• Uniform reporting of different elements of the study – Background
– Methodology
– Statistical approach
– Results
– Discussion
– Funding sources
• Requirement for publication by all major academic journals
Division of Population Health Sciences
Irish Gerontological Society PhD Study Day 2013
Standardised reporting guidelines
• Follow appropriate guidelines http://www.equator-network.org/home/
• Protocols for RCTS: SPIRIT (only published in January 2013)
• RCT: CONSORT
• Observational studies: STROBE
• Diagnostic accuracy: STARD
• Systematic reviews: PRISMA
• Qualitative research (focus groups and interviews): COREQ

4. Methods
• Study sample – Inclusion criteria
• Describe and justify study sample
• Address any potential biases – invalidate study results?
– Exclusion criteria
• Justify reasons for exclusion e.g. feasibility or safety
• Address any potential biases – invalidate study results or applicability to more general samples
– Consider availability of study sample
Division of Population Health Sciences
Irish Gerontological Society PhD Study Day 2013
4. Methods
• Data required – Explanatory variables
• Potential risk factors, protective factors, confounders
– Outcome variables
• Dichotomous (dead/alive, yes/no), continuous (time, blood loss), ordinal (Likert scale)
Example
• Smoking: definition, quantification, categories
• Osteoarthritis: case definition, definition of a control
Division of Population Health Sciences
Irish Gerontological Society PhD Study Day 2013
4. Methods
• Data collection – How?
• Interview, observation, record review, clinical assessment
– By whom? • Interviewers, clinician (training effect)
– Tools? • Questionnaires – self or interviewer administered – face to face or
telephone interview
– Blinding? • Blinding of outcome assessor, patient
Division of Population Health Sciences

4. Methods
• Data analysis/ sample size calculation – Describes all data analysis issues
• Data management procedures
• Analytic approach
• Sample size/power calculations
• Interview, observation, record review
– Common critique • Insufficient description of analytic approach
• Inadequate control for confounders
• Insufficient description of the handling of missing data
• Not enough consideration of attrition

Remember……
The crucial examination of your PhD candidacy is that of the thesis, not the viva.
• “40% of examiners . . . said that the decision about the thesis
was made before the viva. In 74% of cases the viva served merely to confirm the examiners’ opinions of the candidate. . .”
(Jackson and Tinkler 2001: 361)
