The most widely used technique is the case history, which requires access to various information sources, including school and medical records. A case history can also provide important family information. The diagnostic interview is another approach that provides useful information. It consists of a direct face-to-face session during which the psychologist asks the client about key life areas. It typically focuses on issues related to the current problem.
