The first and foremost question block to answer to the potential participants is everything regarding the participation. As the Consent documentation will be the participants' first informative contact with the project, it is important to cover who can participate and whether there are any inclusion criteria.
The participants will definitely want to know what will be the procedures, steps, and the length of the project, as well as the possible benefits or financial reimbursement that the participants might receive.

Another essential block of information to cover is data protection and ethics regulations to ensure the participants that their personal data will be safe. The personal data groups that will be gathered and the goals for which the data will be processed must be identified, as well as the legal basis of their processing and the period of time they will be stored.
NB! If the project is planned to be based in the European Union, it is highly recommended to consult the Article 13 of the General Data Protection Regulation for details on what information must be communicated to the data subject when personal data is obtained from them. In case of other locations around the world, it is highly recommended to consult the respective legislation on communication with data subjects when personal data is obtained and processed.

Yet another important topic of the participants' interest to cover is the potential risks or discomforts that the participants should be aware of before committing to the project. However, if there are none known, it will be reassuring for the participants to know that, as well.

Last but not least, it is important to introduce project team to the participants for transparency and clarity purposes. This is the best time to let the participants know who the project administrators are, as well as introduce all project partners or sponsors if there are any. This way an environment of clarity and safety will be ensured which will, in turn, encourage honest engagement.
