Losing a close person is one of the most common stressful life experiences. While most people gradually adapt to the loss, some continue to experience disabling grief reactions. This condition, known as prolonged grief disorder (PGD), involves persistent longing and preoccupation with the deceased for ≥12 months post-loss. This study aims to estimate the prevalence of PGD among Dutch bereaved adults, using a large representative sample. It also examines which factors increase the risk of poor mental health following bereavement. Importantly, the study also focuses on positive psychological outcomes, including well-being. Understanding why some people suffer severe distress while others cope and even thrive after loss is essential for enhancing the quality of bereavement care. Participants who experienced a loss ≥12 months earlier will complete surveys at three time points, each 6 months apart, to examine the course and correlates of mental health over time. By exploring both mental problems and well-being, this study aims to provide a more comprehensive understanding of how people respond to bereavement.
