John Bowlby's (1982) attachment theory can be applied to an existing therapeutic framework to enhance the effectiveness of therapy. Using the Adult Attachment Inventory (AAI), a therapist can identify the type of attachment the client formed with his/her caregivers, and use this to navigate an authentic attachment between client and therapist. This paper focuses on the application of attachment theory in adolescent counselling, because in adolescence a person has the linguistic and psychological constructs in place to recognize the significance of attachment, and can take advantage of the brain's adaptive state before brain development reaches its adult configuration.
