Charlotte Vrijen

Postdoctoral researcher

University of Groningen

Charlotte Vrijen is a postdoctoral researcher at the University of Groningen. Her main research interest is positive bias, i.e., the phenomenon that many people view the world more positively and brightly than it really is. Positive bias may protect us from developing mental health problems.

During her PhD, Charlotte investigated absence of positive bias in adolescence as an underlying mechanism of depression. She combined longitudinal data collected every 2 to 3 years with more fine-grained momentary assessments, laboratory tasks, and biomarkers.

Charlotte’s current research focuses on the intergenerational transmission of social experiences. Her aim for the future is to combine both lines of research and investigate when and how individual differences in positive bias arise, and what role genetic vulnerabilities and parenting play.

Charlotte is passionate about improving scientific practice. She is a member of her department’s Ethics Committee and of the Open Science Community Groningen, where she gives pre-registration workshops. Examples of open science practices in her work are pre-registrations, sharing syntax and data, and publishing open access.

Work experience

 
 
 
 
 

Postdoctoral researcher

University of Groningen

Aug 2018 – Present The Netherlands
My postdoc is part of a larger project on intergenerational transmission of social experiences. I coordinate the genetic part of the larger project, create polygenic risk scores, recently wrote a meta-analysis on outcomes of bullying perpetration for the perpetrators, and supervise a PhD student, bachelor students, master students, and interns.
 
 
 
 
 

PhD in psychiatry

University Medical Center Groningen

Dec 2013 – Aug 2018 The Netherlands
My second PhD was part of the ‘No fun no glory project’, a biopsychosocial investigation of loss of pleasure in young adults. This project involved an exploratory intervention study of lifestyle advice based on momentary assessments and a tandem skydive, preceded by a screening questionnaire among almost 3000 young people.

PhD in philosophy

University of Groningen

Sep 2001 – Aug 2005 The Netherlands
My PhD in philosophy was part of the project ‘The Critique of Language in the Philosophy of the Later Middle Ages, Renaissance and the Twentieth Century. Patterns of Conceptual Similarity in Philosophical Argument.’ I wrote my dissertation on the published an unpublished writings of the Twentieth century Oxford philosopher Gilbert Ryle.

Skills

Statistical analysis

Multilevel meta-analysis, multilevel regression analysis, longitudinal data analysis, network analysis of ecological momentary assessments. Experience with R, Mplus, SPSS

Data collection

I coordinate biomarker collection and analysis and have collected data with surveys, momentary assessment tools, and behavioural tasks. I also have experience with lifestyle interventions.

Genetics in social science

I coordinate the genetic part of the CAPE project, including the construction of so-called polygenic scores (indexes of genetic predisposition to specific phenotypes).

Open science and ethics

I am a member of my department’s Ethics Committee and of the Open Science Community Groningen, where I give regular pre-registration workshops. Examples of open science practices in my work are pre-registrations, sharing syntax and data, and publishing open access.

Teaching/supervision

I am daily supervisor of a PhD student working on parent-child transmission of peer problems, and have supervised bachelor and master theses, as well as student interns and assistants. During my PhD, I was scientific coach for medical students.

Reviewing

Reviewer (on occasional basis) for the Journal of Child Psychology and Psychiatry, the International Journal of Cognitive Therapy, Frontiers in Psychology, and Psychology Research and Behavior Management.
