Randomized Controlled Trials of Psychological Interventions

Dit vak wordt in het Engels aangeboden. Omschrijvingen kunnen daardoor mogelijk alleen in het Engels worden weergegeven.

Doel vak

The aim of this course is to have an understanding of the major
methodological issues in designing a randomized controlled trial (RCT)
of a psychological intervention in mental health care. Students should
be able to identify strengths and weaknesses of the designs of published
trials and be able to design a trial themselves.

Inhoud vak

The course focuses on: the research questions which can be answered by
a RCT, types of RCTs, design of a RCT according to the CONSORT statement
(e.g. phrasing of the research question, choice of control group,
blinding, randomization, power analysis, in- and exclusion criteria,
measuring outcomes, treatment integrity),analyzing and presenting data
(including how to deal with missing data), and economical analyses.
Furthermore, we discuss medical ethical issues in performing a trial as
well as practical aspects of carrying out a RCT.


(almost) every meeting consists of 45 minutes of theory and 45 minutes
of practical (e.g. critically reviewing a paper; designing part of a
trial, presentations of PhD students running a RCT).


There is an exam with open-end questions. Students also have to write a
research proposal of a RCT (pre-specified format). The exam weighs 2/3
and the paper 1/3 of the final grade. Both the exam and the paper have
to be sufficient (6 or higher).
