In the literature, there have been many studies devoted to adjustment to bereavement as well as to the variables related to it. The objective of our study is to determine and compare mourners’ reactions many years after their loss as well as the factors generating complications, using two samples : death by suicide (n = 31) and death due to sickness (n = 38). Self-administered questionnaires were used in our inquiry to measure mourners’ reactions to death (depression, traumas, and distress) and their bond style with the deceased person. We believe that two factors (variables) could lead to a complicated bereavement and necessitate an intervention : an insecure bond style and/or intense traumatic reactions.
