The researcher needs to consider the study from the perspective of the participant and consider any risk of the participant's psychological well-being, physical health, personal values and dignity
After the participant has completed their role in the study, the researchers should give them a debriefing to explain the reasons for the research, any outcomes, and check for any harm caused
The debriefing can be a time to deal with any ethical issues such as revealing deception, reminding participants of their rights, and checking for and offering support for any harm caused
