This course focuses on different forms of psychotherapy and research into its effectiveness. The first introductory lecture provides a short history of psychotherapy. The following four lectures will discuss the theoretical basis and techniques of the main psychotherapy orientations (i.e., psychoanalytic and psychodynamic, client-centered, cognitive-behavioural, and family therapy). For these lectures, practitioners of these orientations are to discuss and demonstrate techniques used. Finally, two lectures will provide an overview of research findings in psychotherapy. Besides presenting research into the effectiveness of psychotherapy, these lectures also present research into the importance of theoretical orientation, as well as therapist, client and relational and technical factors for therapy outcomes. Where applicable, ethical considerations will be discussed.

The integral exam consists of a multiple choice examination. The final grading is calculated on a 70% (multiple choice): 30% (open-ended questions) weighting. The resit will also consist of examination including multiple choice and open-ended questions.. It is not possible to resit part of the examination. For both parts of the exam questions and answers will be in English.

The exam consists of 40 multiple choice questions with four answering categories and 2 open-ended questions.

The Institute of Psychology uses fixed rules for grade calculation and compulsory attendance.

Disciplinary measures will be taken when fraud is detected. Students are expected to be familiar with and understand the implications of these three policies.

After the examination, a one hour session will be reserved for students to ask questions about the integral exam.
