Summary
Maartje Witlox (1992) graduated at Utrecht University (Clinical and Health Psychology) in 2015. After having obtained her degree, she worked as both a research assistant and clinician in a mental health care practice specialized in anxiety disorders. Since January 2017 she works as a PhD student at Leiden University. Her research focuses on the treatment of anxiety complaints in the elderly.
Research
My research project is named C.A.L.L. : Controlling Anxiety in Late Life. The main goal of this project is to conduct a RCT to evaluate the (cost)effectiveness of a blended treatment for older adults with anxiety complaints. This low-treshold intervention combines the online self-help program ‘Living Life to The Full’ with a limited amount of face-to-face contacts with a counselor.
