Informed participation is an ethical and legal requirement for research involving human participants. It is the process where a participant is informed beforehand about all aspects of your research to enable the participant to make an informed decision on their willingness to participate in your research. 
Informed participation is an essential requirement prior to every research involving people as subjects for research. It involves informing the subject about his or her rights, the purpose of the research, procedures to be undertaken, potential risks and benefits of participation, expected duration of the research, the extent of confidentiality of personal identification and demographic data, so that the participation of subjects in your research is entirely voluntary.  
Informed consent - when a person actively provides consent to participate in your research - is also increasingly important for use of data after your research, as failure to properly address issues of consent may restrict the opportunities for initial use of data, the publishing of your results and the sharing of the data.

NOTE: you always have to inform people who participate in your research about your research. Obtaining explicit consent (e.g. signing a form or tick a box) is not always required; if research data is gathered completely anonymously you do not need to register the participants' consent


Participants, or their legal representatives, must be given ample opportunity to understand the nature, purpose and anticipated consequences of research participation. So that they will be able to give informed consent to the extent to which they are capable of doing so. Please note that not all human beings are capable of consent. Individuals with the capacity or competence to consent:

  • are 16 years or older (adult);
  • have the capacity to make choices about a proposed course of action;
  • know about the risks, benefits, and alternatives;
  • understand that consent is ‘voluntary and continuing permission’;
  • understand that consent ‘can be withdrawn at any time’.

More info on individuals competence to consent on CCMO website (EnglishDutch).


Consent is one of the six legal grounds for lawful processing of personal data, often consent is the most appropriate legal basis in research. If personally identifiable information of individuals will be processed in your research, active consent is required, according to EU General Data Protection Regulation GDPR. Consent under the GDPR is: valid, freely given, unambiguous, specific, informed and explicit actively given consent. The 'consent' requires action: it needs to be given by a written(signed)/oral statement or by clear affirmative action. Silent consent, inactivity or pre-ticked boxes are not valid. 

If you process sensitive personal data than explicit consent is required for collecting those data. For an explanation on personally identifiable information check the UT Personal Data website on privacy rules and definitions.


The informed consent procedure consists of an information sheet AND an informed consent form 

Specifically, the information provided in advance addresses (where applicable):

  • the voluntariness of participation;
  • the nature and purpose of the investigation, including if the data collection is meant only for training purposes
  • any reasonably foreseeable factors regarding the nature, purpose, and duration of the research that may influence participants’ willingness to participate (such as the extent of strain, potential risks, and discomfort)
  • the right to decline to participate and withdraw from the research at any time, without any negative consequences, and without providing any reasons;
  • any recording of voices and images (where applicable);
  • confidentiality protection and the limitations thereof;
  • procedures for incidental findings (where applicable);
  • additional insurance guarantees (where applicable);
  • period of time to which the consent applies;
  • time and nature of data storage
  • re-use of specified data in the current, future or other research;
  • incentives for participation;
  • names and details of the responsible researcher and contact person(s) for questions about the research and rights of research participants;


Here you can find several informed consent forms. They are examples, which can be used as a template for your own, customized version. Before signing the informed consent form, participants need to be provided with sufficiently detailed information on the study so that they can make an informed, voluntary and rational decision to participate.
