Food and nutritional sciences research project guidance: Ethical approval

Resources and links to guide you through your research project.

Research with human volunteers, and some other research, will require prior ethical approval. The University requires ethical clearance to be obtained when personal data is collected either by questionnaire or by the analysis of human samples. This process can take up to two months, and it is therefore important to start the application as soon as possible. Discuss this with your supervisor as soon as possible so that the appropriate forms are submitted to the School or Faculty Ethics Committee on time. Note that there are three additional forms for all studies which will be using the Hugh Sinclair Unit of Human Nutrition.

  • Food acceptability trials – taste panels
  • Questionnaires, surveys, focus groups, interviews
  • Human data records

Getting ethical approval

Your ethics proposal goes to the University Ethics Committee. it must include:

  1. How participants are being selected
  2. Arrangements to inform a participant's GP
  3. How confidentiality will be ensured
  4. Arrangements for publishing research results
  5. Arrangements for providing subjects with results

It may be approved at School instead of University level if research:

  • Does not involve patients of the health or social services
  • Involves participants who can give free and informed consent
  • Does not involve questions likely to cause distress
  • Does not involve an element of risk to the researcher or participant
  • Does not involve subjects in a special relationship with the investigator
