Despite a growing need for mental health services for adolescents, treatment access among adolescents remains poor. Psychologists practicing in the United States are subject to highly variable legal standards for consent and confidentiality of minor clients, which can further suppress treatment accessibility. States permit independent consent for minors according to a wide range of criteria, but whether these criteria are empirically derived remains unknown. Inconsistencies between the law and ethical obligations for psychologists can expose minor clients to harm and force (...) psychologists to make disclosures that violate patients’ rights and ethical standards. These harms may be particularly severe for clients from vulnerable populations such as sexuality and gender diverse youth (SGDY). To prevent ethical dilemmas, psychologists and professional organizations should work toward an empirical understanding of the adolescent capacity to consent to mental health care and use that understanding to promote uniform consent and confidentiality standards.
