Experimental Clinical Psychology


Entry requirements

Only open to master’s students in Psychology with specialisation Clinical Psychology.


Clinical psychological research is often concerned with investigating the causes of abnormal behaviour or with its treatment. A range of study designs can be 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

Students learn:

  • To reflect upon the strengths and weaknesses of research designs typically used in clinical psychology and toassess research papers on the merits of their chosen research strategies and design;

  • The standards of reporting on various types of clinical research, including the rationale for these standards; and

  • About recent developments in psychological treatments of psychiatric disorders.
