Ethics approval is not a bureaucratic obstacle designed to slow down research. It exists for genuinely important reasons. But the process can be navigated much more efficiently than most first-time applicants realise — and common mistakes cause delays that are entirely avoidable.
The Most Common Causes of Delay
Ethics committees most frequently request revisions for these reasons: consent forms written in language that participants wouldn't understand (too technical, too long), inadequate description of how sensitive data will be stored and protected, insufficient justification for sample size, unclear explanation of risks to participants, and methodology descriptions that don't match the stated research aims.
None of these are surprising concerns. They're all things that a careful researcher would ask. Write your application as if you're answering these questions proactively.
Your Consent Form Is Not for Ethicists
The informed consent form should be written for your target participants, not for the ethics committee. If you're recruiting nurses, write at a professional but non-academic level. If you're recruiting general public, write at approximately an eighth-grade reading level. Ethicists will immediately flag forms that use technical jargon participants won't understand.
Data Protection Must Be Specific
Vague statements ("data will be stored securely") are increasingly insufficient. Be specific: "Data will be stored on an encrypted, password-protected university server. Only the named researchers will have access. Data will be retained for [X years] and then deleted using [method]. Anonymisation will be applied by [specific procedure] before analysis." This level of specificity demonstrates genuine data protection thinking.
Include Your Statistical Rationale
Ethics committees are increasingly asking why you need the sample size you've specified. Including a brief power analysis — even just a sentence or two with a G*Power calculation reference — demonstrates that your sample size is evidence-based rather than arbitrary. Boss Statistics can help you produce a defensible sample size justification for your ethics application.
Respond to Queries Quickly and Completely
When an ethics committee sends queries, the clock pauses until you respond. Researchers who respond within a few days with complete answers — addressing every point rather than just the most convenient ones — see dramatically shorter overall timelines than those who respond slowly or partially.
