Chapter 5 provides an overview of a clinician's functional competencies with regard to psychological interventions with children and adolescents, and focuses on levels of intervention competency that permit a psychologist to provide good quality care to the child clients and their families–level of competency that is expected to be attained by well-trained psychologists in the years shortly after they have received their terminal degrees. It first briefly covers basic procedural issues in establishing the therapy contract, and then discusses types of therapeutic procedures that psychologists may competently use with their clients.
