First of all, we followed up at three time points after the loss, after one and a half years and then after two and three years. We found an extremely high number of parents who struggled with complicated grief reactions, around 80% of them, and more than 60% with more post-traumatic stress reactions to a level where they would be probably be diagnosed.
We thought that had to do with the extreme number of traumatic reminders they had to face in the years afterwards with the court case going on and with the murderer being in the media all the time. We also think the way the 69 youths were hunted and killed at the island played a part in having such a great effect on parents.
Just to be clear, you're talking about grief following all kinds of child loss, not only those at the early stage of life.
