I work as assistant professor at University of Twente, senior researcher at Fund Victim Support, and guest researcher at University of Groningen, Utrecht University (NL), Aarhus University (DK) and University of New South Wales (AUS). My research is focused on the definition, assessment, prediction, and treatment of disturbed grief in bereaved adults and children. Â
In projects among people who experienced losses because of a long-term disappearance, homicide, MH17 plane disaster, traffic accident, COVID-19, and Russian war in Ukraine I examine risk factors and treatment of distress. I have authored more than 80 peer-reviewed journal articles. According to a bibliometric study from 2023 on the most productive/influential authors on the topic of prolonged grief disorder (https://doi.org/10.1080/07481187.2023.2196734)Â I am the third most productive academic in the world.
As main applicant/principal investigator, I received funding (> 870.000 euros) for ten research projects, including a NWO Veni-grant in 2022. As co-applicant, I received funding (>250.000 euros) for four research projects. Funding agencies that financially supported my work are Fund Victim Support, Dutch Ministry of Justice and Safety, NWO, SASS, Stichting Catharine van Tussenbroek, and Utrecht and Twente University Fund.

Current projects
The TALE study
TGI-CA Assessment after Loss in Europe
The primary aim of the TALE-study is to evaluate the psychometric properties of the Traumatic Grief Inventory - Clinical Administered (TGI-CA). The TGI-CA is an interview that is developed to assess pathological grief criteria (proposed for inclusion) in DSM-5 and ICD-11. During this study data will be collected among Dutch and German-speaking bereaved people by telephone interviews. Collaborators: drs. Minita Franzen (University of Groningen), dr. Carina Heeke (Freie UniversitÀt Berlin) en prof. dr. Paul A. Boelen (Utrecht University and Arq National Psychotrauma Centre).
Grief after the MH17 plane disaster
Aim: to examine the course of symptoms over time in people who lost one or multiple significant others due to the plane disaster with flight MH17. Among others latent class growth modeling and cross-lagged panel analyses are used to analyze the data. Furthermore, the effectiveness of a treatment for this group will be evaluated in a randomized controlled trial. Collaborators: prof. dr. Jos de Keijser (University of Groningen), prof. dr. Paul A. Boelen (Utrecht University and Arq National Psychotrauma Centre), prof. dr. Geert E. Smid (Centre '45 and Arq National Psychotrauma Centre), and dr. Angela Nickerson (University of New South Wales, Australia).
Treatment of disturbed grief after the death of a loved one during the COVID-19 pandemic
Grief during the pandemic
This PhD-project consists of two trials: 1) In a randomized controlled trial the effects of an online unguided grief-specific cognitive behavioral therapy (vs. waitlist controls) will be evaluated in people who lost a loved one during the pandemic. 2) In a controlled trial the effects of an online guided grief-specific cognitive behavioral therapy (vs. online unguided grief-specific cognitive behavioral therapy) will be evaluated in people who lost a loved one during the pandemic. Research team: Lyanne Reitsma (PhD candidate) Lonneke Lenferink (Principal Investigator/main applicant) Paul Boelen and Jos de Keijser (co-applicants)
CONNECT project
CONNECT
The aim of this project is to examine the course and determinants of psychotrauma complaints related to the COVID-19 pandemic in the general Dutch population. This is a longitudinal survey study among over 2000 Dutch people. This project is part of a pan-European study on the positive and negative consequences of the COVID-19 pandemic executed in eleven European countries. Collaborators: European Society for Traumatic Stress Studies (ESTSS), Nederlandstalige Vereniging voor Psychotrauma (NtVP), prof. dr. Trudy Mooren (Utrecht University, Centre '45), drs. Suzan Soydas (Utrecht University), dr. Joanne Mouthaan (Leiden University), drs Marloes Eidhof (Radboud University, Reinier van Arkel), dr. Marie-José van Hoof (Leiden University) en dr. Simon Groen (GGZ Drenthe)
The Aarhus Bereavement Study
TABstudy
The Aarhus Bereavement Study (TABstudy) is an ongoing multi-wave, registry-based cohort study, examining grief reactions in bereaved adults led by associate prof. Maja O'Connor at Aarhus University (Denmark). Aarhus University granted a research visit in fall 2022 so I could collaborate on this project by analyzing data among bereaved families using structural equation modelling.
TrafVic
Aim: to identify risk factor for developing psychological complaints among people who lost a significant other due to a traffic accident. In addition, the effectiveness of an online treatment for reducing psychopathology levels will be evaluated. Collaborators: prof. dr. Jos de Keijser (University of Groningen), prof. dr. Paul A. Boelen (Utrecht University and Arq National Psychotrauma Centre), prof. dr. Geert E. Smid (Centre '45 and Arq National Psychotrauma Centre), and dr. Maarten Eisma (University of Groningen)
The therapeutic effects of "GriefHelp"
Aim: to evaluate the effectiviness of a psychological intervention for reducing prolonged grief symptoms in minors who lost a significant other. Collaborators: prof. dr. Paul A. Boelen (Utrecht University and Arq National Psychotrauma Centre) and dr. Mariken Spuij (Utrecht University)
Measurements Archive of Reactions to Bereavement from Longitudinal European Studies (MARBLES) project
Aim: to develop an international data-archive for secundary analyses on Findable, Accessible, Interoperable and Reusable (FAIR) longitudinal (non-intervention) grief data in adults. Collaborators: prof. dr. Paul A Boelen (Utrecht University and ARQ national psychotrauma centre) and Nancy Kassam-Adams (Childrenâs Hospital of Philadelphia and the University of Pennsylvania Perelman School of Medicine, Philadelphia, USA)
Toward personalized bereavement care: Examining individual differences in response to grief treatment
Prolonged grief disorder is a debilitating condition, affecting 10% of bereaved people. To date, studies evaluating treatments for prolonged grief have focused on symptom change on a group-level, ignoring individual variability in grief-responses. Personalized prolonged grief treatment may enhance treatment outcomes. This project contributes in three ways to personalized treatment for prolonged grief, by: (i) improving the understanding of differences in grief-trajectories in response to treatment for prolonged grief using a novel FAIR data-archive; (ii) examining grief in daily life; (iii) offering dynamic support in daily life to treat prolonged grief. 2022-2026 Veni-grant NWO
TrafVic Kids
The aims of this PhD-project (2020-2024) are to: 1) develop and validate a clinical interview to assess prolonged grief disorder (PGD) symptoms in children and 2) to develop and evaluate a online treatment for PGD in children bereaved by a traffic accident. PhD-student is Iris van Dijk Promotores: prof. dr. Paul Boelen and prof. dr. Jos de Keijser Co-promotores and daily supervisor: dr. Lonneke Lenferink
