Legally, a child under the age of 18 years cannot consent to their own treatment (there are exceptions). The consenting parent/legal guardian has access to their child’s treatment. Clinically, it is beneficial for a teenage client to create a safe relationship with their therapist where they can share information openly. If a teenager is worried about a parent finding out the content of their session, they will often withhold information resulting in a lack of progress toward goals. Prior to initialing treatment, it is important for a therapist to discuss the expectations with the parent and teenager regarding what and how information with the parent/s is discussed.
