Grief is a normal, dynamic and multidimensional process, which relates to the individuality and uniqueness of reactions to loss. However, complicated grief is a syndrome where normal grief is unusually prolonged because of complications in the natural healing process. Approximately one third of grieving individuals develop complicated grief symptoms. The individuals suffering from complicated grief tend to report clinical complaints that refer to anxiety, depression, psychical symptoms and life-threatening behaviours. The aims of this study were: to identify which psychother-apy-based interventions were designed for the treatment of complicated grief; and to make an infer-ence about the effect of these interventions.
