I am assistant professor in mental resilience at the University of Twente and postdoctoral research fellow at KU Leuven. I am interested in how people deal with stress in their daily lives, and what the consequences are for their resilience and the development of mental illness. Additionally, I develop mobile interventions aimed at learning to cope with daily stressors.

Expertise

  • Psychology

    • Negative Affect
    • Positive Affect

My research focuses on the role of stress and stress recovery in the development of psychopathology and early interventions focused on coping behavior in the context of stress. To this end I use experience sampling methodology, passive monitoring, and experimental lab tasks.

CORE

Coping and stress Recovery in daily life

Individuals in early stages of mental illness need more time to recover from daily life stressors, resulting in persistent negative feelings. Maladaptive coping behaviors may underlie this delayed recovery. If we would be able to predict the moments in daily life where the recovery process malfunctions, we could offer treatment (i.e. alternative coping behaviors) in the very moment it is needed. In the CORE study, we investigate how we can predict the moments during the day where stress recovery hampers in individuals in the early stages of mental illness. To do this, we use a combination of high-tech wearable devices that continuously measure bodily responses (i.e. heart rate, sweat, and skin temperature) and a diary method assessing momentary feelings, both in a controlled setting (a lab) and one week in daily life. Specifically, we investigate how the emotional recovery process is associated with the bodily response if we can use the responses from the lab and the bodily response in daily life, to develop a statistical model that can detect moments of stress in daily life, and predict how long the affective recovery will take if the momentary coping behavior is related to stress recovery.

Finished projects

SMILE

Study on mental effort in the lab and in daily life

Stress is believed to play a crucial role in the development of a large variety of mental and physical disorders in vulnerable individuals, which is reflected in an individual’s reactivity to acute stress. However, prospective studies on the effects of stress-reactivity, as well as those on the effects of treatment on stress-reactivity, struggle with the challenges of repeated stress induction using the same experimental task. In the SMILE project, we used a standardized stress task to induce psychosocial stress twice in the same individuals. With this project, we aim to assess the reliability and ecological validity of the task in its capacity to trigger a stress response twice within a week and ascertain that it has no aversive long-lasting effects.
