In ""Evidence-Based Treatment"", Larry E. Beutler demonstrates his research-directed approach to therapy. Dr. Beutler uses data gathered in a presession assessment to tailor his approach to working with the client. The principles on which this method is based have been proven to make therapy more targeted and therefore more effective. In this session, Dr. Beutler works with a young man suffering with depression who wants to be able to enjoy life again. Dr. Beutler looks for relationship themes and at the client's family systems for insight into the sources of the client's depression and passivity, and helps to increase the client's self-esteem and sense of control over his own life.
