More information about Kim de Jong

Kim de Jong earned her doctoral degree in clinical psychology from Leiden University in 2012. Before that, she received her master degree in clinical psychology and in psychological methods at the University of Amsterdam in 2000. After graduating from the UvA, she started working as an applied researcher at GGZ Noord-Holland-Noord, a mental health care institution in the Netherlands. During that period, she visited Michael J. Lambert at Brigham Young University for four months. She started as an Assistant Professor in Clinical Psychology at Leiden University in 2013, but received the NWO Rubicon grant that year, which provided her with the opportunity of a Visiting Scholarship at the University of Pennsylvania, where she worked with Robert J. DeRubeis. Since September 2014, she is back in Leiden as Assistant Professor in Clinical Psychology. She also has a small private practice.


Her research focuses on understanding differences in treatment outcomes between organizations, therapists and patients, as well as developing and testing interventions that improve outcomes in routine clinical practice. Kim has two major research lines: personalized mental health care and therapist effects. In personalized mental health treatments are tailored towards the individual patient, based on their characteristics. Kim works with large databases of outcome measurements to predict which interventions work best for which patients. The therapist effects research line focuses on assessing why certain therapists perform better than others. She also investigates interventions that aid therapists to offer more effective care, such as Routine Outcome Monitoring (ROM) feedback, deliberate practice and training therapeutic skills.
