Shared decision-making in adolescent healthcare: a literature review of ethical considerations.

• Although adolescents wish to be involved in health decisions, shared decision-making in adolescents is underexplored • Adolescent shared decision-making is different from pediatric and adult shared decision-making, and is ethically complex due to the adolescent's growing autonomy What is new: • Adolescent SDM involves three-way interactions between the adolescent, healthcare professional and parents • In adolescent shared decision-making, involving or excluding a stakeholder and sharing or withholding information are ethically value-laden steps • Research is needed to further understand the roles of adolescents' personal value systems, extended or reconstituted families and decision aids in shared decision-making.
