Kaya Peerdeman's research focuses on the effect of biopsychosocial mechanisms on treatment outcomes. She specifically focuses on how expectations shape health.
Research
Kaya Peerdeman' research specifically focuses on how expectations shape health, for example through examining placebo and nocebo effects (i.e. beneficial and adverse treatment outcomes not attributable to active treatment components, respectively). She also has a particular interest in violated expectations and uncertainty. She examines how they impact health outcomes like pain and other symptoms (e.g. itch, stress) and what biopsychosocial factors are involved (e.g. anxiety, doctor-patient communication). Central in her work are mechanistic studies bridging fundamental and applied research. She works to translate findings to clinical practice in order to optimise treatments.
Short CV
Kaya Peerdeman completed the Research Master Psychology and the Master Clinical Psychology at the University of Amsterdam (2011). Her PhD research commenced at the Radboud university medical center and continued at Leiden University under the supervision of Prof. dr. Andrea Evers, Prof. dr. Madelon Peters, and Dr. Antoinette van Laarhoven. She defended her PhD thesis ‘Harnessing placebo effects by targeting expectancies’ in February 2018. She then worked as a postdoctoral researcher in the research group before becoming an assistant professor.
