Consent
For research involving children under 12 years of age, consent from both parents/legal representatives or the guardian is required to participate in the study. Adolescents 12 to 16 years of age give consent together with their parents/legal representatives or guardian. Adolescents 16 years and older give their own consent.
If a child reaches the age of 12 while participating in the study, the child must also give consent to participate in the study. In that case, the parents/legal representatives or guardian have already given consent earlier. If a child reaches the age of 16 while participating in the study, no further action is needed as the child has already given consent.
