Janna obtained her bachelor degree in Psychology and her master degrees in the research master Development and Socialization in Childhood and Adolescence (Cum Laude) and the academic master Clinical Child and Adolescent Psychology (Cum Laude) at Utrecht University. She is currently working as a PhD candidate at the Department of Clinical Child and Family Studies at Utrecht University on the project: ACT your way: A transdiagnostic intervention for multiple disorders in transitional-age youth. The aim of this project is to investigate the (cost)effectiveness of ACT your way and to examine for whom (moderation analyses) and how (mediation analyses) this intervention works. ACT your way is a transdiagnostic intervention specifically developed for transitional-age youths (i.e., youth aged 15 to 25) with problems concerning their identity, autonomy, or psychopathology. ACT your way is based on Acceptance and Commitment Therapy (ACT). The goal of ACT is to increase psychological flexibility: an individual’s acceptance of negative feelings, thoughts and physical sensations and the ability to choose an adaptive (and more effective) response.
