Job description

The NWO-Vici project focuses on unraveling the role of placebo and nocebo mechanisms (e.g. conditioning) for the sensitization of insufficiently explained symptoms in healthy subjects and patients with insufficiently explained symptoms. Placebo and nocebo effects (i.e. positive and negative outcome expectations that result in positive or negative outcomes, respectively) explain 25-50% of outcomes in various health problems, including somatic symptoms, such as pain, itch or fatigue. While far more attention has been directed to the role of placebo effects, studies suggest that nocebo effects contribute even more to somatic symptoms. However, there is not yet an integrated approach that studies psychoneurobiological nocebo mechanisms with advanced methods (e.g. using conditioning approaches, pharmacological modulations, fMRI, psychophysiological reactivity measures) for the sensitization and desensitization of somatic symptoms. In the project, a comprehensive psychoneurobiological approach is tested to 1) study the causal role of nocebo mechanisms in the sensitization and desensitization of somatic symptoms; 2) identify patients at risk for sensitization; and 3) develop innovative treatments for desensitization of somatic symptoms. For this purpose, a unique set of combined psychoneurobiological methods is applied in experimental, prospective, and treatment studies both in healthy subjects and in patients with insufficiently explained somatic symptoms. This project progresses key theoretical knowledge of the main psychoneurobiological nocebo mechanisms of various somatic symptoms. Findings open up new horizons for prevention and treatment, by identifying patients at risk for symptom sensitization and generating targeted treatments for symptom desensitization and recovery.

The current PhD project focuses on the causal role of nocebo mechanisms in the sensitization and desensitization of somatic symptoms. For this purpose, a broad set of psychoneurobiological methods will be applied in a series of experimental studies, combining various techniques of psychological conditioning, psychophysiological assessements, pharmacological inductions and fMRI. You will be responsible for conduction different clinical-experimental studies of this PhD project. You will write scientific, peer-reviewed publications, resulting in a PhD thesis.

The PhD projects will be imbedded in the national research school Experimental Psychopathology (EPP) and Leiden Institute of Brain and Cognition (LIBC). In addition, we offer several other relevant possibilities for education and training, including courses on data management and academic skills, as well as participation in relevant international conferences.
