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.

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

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.

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 Universität 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).

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)
