Involving children in decisions about enrolment into a clinical trial: child assent

When you are approached to give consent for your child to take part, you may also be given an assent form for your child (see below). Children under 16 cannot give formal legal consent, which has to be given by a parent or guardian, but they can and should be involved in the decision as far as possible.

Prior to giving consent to take part, it is important that families receive and understand…

Assent means children give their permission or agreement to take part in trials. It requires that children understand the research process and are informed about what they are expected to do. In considering assent, children can talk about their views and any worries about participating in trials. Doctors need to listen to the opinion and wishes of children who are unable to give full consent to a trial, and do their best to gain their assent. All children have the right to receive information given to them in a way that they can understand, and to consider assenting, or not. Both consent from parents and assent from children is needed if a child is to take part in a trial.

For the majority of parents we talked to, consent was their responsibility because their children were under the age of 16 years. Most of them felt that it was important to involve children in the decision in some way, unless they were babies or toddlers, but the extent to which people felt this was possible varied. (See also ‘Making the decision about enrolling your child: parental consent’.)

Some parents talked about their children having their own pack of information. Sometimes the health professionals would come to the child’s home to explain the trial to them. Sometimes they would demonstrate what was involved, for example using Emla cream (a local anaesthetic) when blood samples were required. This involvement of children by health professionals was important to parents and gave children the opportunity to express their concerns and views. In Nikki’s and Chris’s case, their daughter was diagnosed with asthma at the age of 18 months; she is now aged 6 years. They were invited to enrol their daughter in a research study on children with asthma who also take inhaled corticosteroids.
