The University of ݮƵ Research Ethics Boards (REBs) have adopted the following definition of a health-related intervention: "An activity or set of activities aimed at modifying a process, course of action or sequence of events in order to change one or several of their characteristics such as performance of expected outcome.” (, 2021, p.6).
Examples of health-related interventions involving study participants are listed below:
- Use of a drug, eye care solution, or medication (marketed or investigational) to assess a positive change in health outcome as a result of the drug, solution, or medication.
- Consuming a food or vitamin supplement to assess a change in nutritional status, insulin level, or other metabolic measures.
- Taking part in a new urine screening test that will be used to determine or rule out a certain disease such as diabetes.
- Testing of a new exercise program with people who have had a mild ischemic stroke to reduce the risk of a subsequent stroke by improving fitness levels.
- Psychotherapeutic approach to a behavioural disorder or other mental illness comparing the outcomes of two or more patient populations with the same diagnosis but receiving different therapies or a trial comparing the outcome of those who have received the therapy with those who are on the waiting list for treatment.
