Experimental Clinical Psychology


Admission requirements

Mandatory course for MSc Clinical students.


Clinical psychological research is often concerned with investigating the causes of abnormal behavior or with its treatment. A range of study designs can used to identify causes of illness, both cross-sectional and longitudinal designs. Treatment evaluation designs range from case reports to randomized clinical trials (RCTs). RCTs have rapidly become the gold standard of evidence in biomedical research. However, the vast majority of studies is observational. Furthermore, it has been argued that RCTs are impractical in some circumstances, and impossible in others.

In this course we will discuss the strengths and weaknesses of cohort-studies, case-control studies and cross-sectional studies for investigating causal relationships. Secondly, we will discuss the strengths and weaknesses of different treatment evaluation designs, as well as the standards of conducting and reporting this research. Recent developments in psychotherapy and psychopharmacology research will be used as examples.

Course objectives

  • Learn to reflect upon the strengths and weaknesses of research designs typically used in clinical psychology.

  • Learn to assess research papers on the merits of their chosen research strategies and design.

  • Learn the standards of reporting of various types of clinical research, including the rationale for these standards.

  • Gain knowledge about recent developments in psychological treatments of psychiatric disorders.
