In some fields of research, it could be helpful to re-use the data for future research and analysis. If it is likely that your data is of this kind and you want to have the option to use the data for other purposes, or for it to be available to other researchers, you must obtain explicit permission and describe what you want the participant to agree to in the Explanatory Statement.
A statement should be included for the participant/s to agree that the information provided can be used in further research projects which have research governance approval as long as their name and contact information is removed before it is passed on. State exactly what permission is to be sought.
