Psychotherapy: Theory, Research & Practice


Entry requirements

Personality, Clinical and Health Psychology or a similar course. This elective course presupposes basic knowledge of psychopathology and psychological interventions for psychopathology necessary for successful completion of the course.


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.

Course objectives

Students will acquire:

  • An understanding of the theoretical basis and techniques of various psychotherapies;

  • Knowledge of the research evidence of the effectiveness of psychotherapies; and

  • Skills in translating scientific knowledge into the daily practice of psychotherapy.

Students must register themselves for all course components (lectures, tutorials and practicals) they wish to follow. You can register up to 5 days prior to the start of the course. The exception here is that first-year bachelor students are assigned and registered for all components in the first semester or academic year by the administration of their bachelor programme. The programme will communicate to these students for which course components and for which period the registration applies.


It is mandatory for all students, including first-year bachelor students, to register for each exam and to confirm registration for each exam in My Studymap. This is possible up to and including 10 calendar days prior to the examination. You cannot take an exam without a valid pre-registration and confirmation in My Studymap.

Carefully read all information about the procedures and deadlines for registering for courses and exams.

Students who take this course as part of a LDE minor or a premaster programme, exchange students and external guest students will be informed by the education administration about the current registration procedure.

Mode of instruction

7 2-hour lectures. The lectures present the theoretical basis and techniques of some major models of psychotherapy as well as an overview of research findings in psychotherapy.

Assessment method

The following information has to be studied for the final exam: a. all the chapters of the custom edition of Wedding and Corsini (195 pages excluding references); b. all the chapters of the book of Cooper (155 pages excluding references); c. the power point presentations of each of the lectures

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. It also follows the policy of the Faculty of Social and Behavioural Sciences to systematically check student papers for plagiarism with the help of software. 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.
