PETRA conducts scientific research into how psychological complaints manifest themselves in daily life. But also how we can improve the quality of care, and which treatment works best for whom. If you participate in PETRA, we ask your permission to do this research. Download more information below about what kind of research we do and how long we keep your data.



PETRA is based on scientific research on the utility of personalized diaries for clinical practice. Find relevant publications of the PETRA team below.
