Research

Nina Komrij's research focuses on the impact of parenting interventions in promoting young children’s mental health, with a particular emphasis on the early prevention of anxiety problems. Her work includes a strong implementation focus, examining how evidence-based interventions can be delivered and sustained in everyday practice through collaboration with public and mental organizations. In her research, she uses several methodological approaches, including randomized controlled trial, single-case experimental design, mixed-methods research, and meta-analytic approaches.

Short CV

Nina has a background in Health Sciences and obtained her master's degree at the VU University Amsterdam in 2020, where she specialized in health promotion and the prevention of health problems. In December 2020, she started with her PhD project focused on investigating an parenting program that aims to prevent the development of anxiety problems in anxiety-prone toddlers, supervised by dr. Leonie Vreeke and prof. dr. Michiel Westenberg. From May 2025, she works as a postdoctoral researcher, building on her PhD research by further examining the working mechanisms of this intervention and the processes underlying its preventive effects on child anxiety.
