[Key considerations in the process of assent in children and adolescents: an integrative review]

Abstract

The participation of children and adolescents in research requires bioethical measures to safeguard their autonomy and well-being through the application of the informed consent process.

Objective: To critically analyze the factors involved in the process of assent/consent in children and adolescents in research.

Methodology: Integrative review of scientific evidence carried out between April and June 2023, from manuscripts published between 2014 and 2023 in Web of Science, PubMed, CUIDEN, and CINAHL databases, using the descriptors Process Assessment OR Assent AND Informed Consent AND Bioethics AND Minors OR Child OR Children AND adolescent OR teenage AND Pediatrics AND Research. Twenty primary articles were found, and the results were subjected to content analysis.

Result: Three categories were identified: shared consent/assent; child-specific factors for giving assent (age of the child to give assent and autonomy of the child to give assent), and key aspects of the assent process (assent form format; assent form content, and context for applying the assent process).

Conclusions: The assent process is a key tool for legal and ethical compliance with the rights of children and adolescents in clinical trial participation. In addition to favoring participation in informed decision-making together with the parents, it is also an instance where the participant's competencies, capacity for understanding, and autonomy are valued.
