Throughout the undergraduate psychology education students take various courses on main and important theories of personality and psychotherapy. Although students are familiar with those theories theoretically, they may lack any information about the application of these approaches onto the cases. Therefore, this course intends to help students study and therefore understand how main theories of psychotherapy can be applied to the cases. The course targets to teach the focal theoretical issues via cases together with helping students to study case formulation based on different approaches. The students are expected to learn to derive basic terminology and the basic concepts of a specific approach, from a presented case.
