Bereaved parents and individuals bereaved by the sudden, unexpected, or violent death of a loved one are at high risk for developing complicated grief. However, preventive interventions for this at-risk population remain scarce. In the present pilot study, an Internet-based intervention for individuals bereaved in the previous 14 months was tested using a pretest/posttest design. A total of 35 bereaved individuals participated in a 3-week manualized prevention program. Counselor and participants communicated exclusively via email. The intervention consisted of the following modules: (1) describing the circumstances of the death, (2) using the life-imprint method to explore the biography and life imprint of the deceased, (3) keeping a daily diary of social activities and sleep hygiene, (4) cognitive restructuring of dysfunctional thoughts, such as responsibility for the death and feelings of guilt, (5) communication within the family, (6) gender-specific coping with bereavement, and (7) bond with the deceased. Completer and intent-to-treat analyses suggest that the intervention led to a significant reduction in symptoms of complicated grief and depression at posttreatment. © PI-ME, 2008.
