The dataset contains longitudinal survey data that was used to examine the reciprocal associations between prolonged grief symptoms and state anger levels. In addition, the data were used to explore whether aspects related to the criminal justice system were related to prolonged grief symptoms and state anger levels.

In our paper titled "Reciprocal relations between prolonged grief and anger in homicidally bereaved people involved in a criminal trial: A four-wave cross-lagged panel model", 237 MH17 bereaved people are included. Here in DANS, the dataset contains data from 225 MH17 bereaved people, because 12 people did not provide consent to any of their data being shared. Participants were eligible to participate if they were 18 years old or older, could understand either Dutch or English, and lost one or more loved ones during the MH17 plane disaster that took place on July 17 2014.

The data were collected 67, 79, 88, and 103 months after the MH17 plane disaster. During each wave of the study, prolonged grief symptoms and state anger levels were assessed, using the Traumatic Grief Inventory Self-Report Plus (TGI-SR+) and the State-Trait Anger Expression Inventory 2 (STAXI-II), respectively. The first wave took place before, the second and third during, and the fourth after the criminal trial. Various characteristics of the criminal trial were assessed at different waves, including whether the participant received monetary compensation and delivered a victim impact statement, how satisfied the participant was with different professionals and the verdict, and the number of statements the participant listened to.

Accessibility Due to the sensitive nature of the dataset, the data can be viewed upon reasonable request.
