Extensive scientific work by my group, including more than 160 scientific publications, has demonstrated that the three major social instruments of healing are altruism, work, and spirituality. These elements provide concrete methods and tools to promote recovery from trauma. They stimulate biological repair, assist in the construction of post-trauma attitudes and beliefs, and shift the survivor from isolation to rejoining the community.The social instruments of self-healing are equally relevant for people facing serious health threats such as cancer. Patients confronting medical illnesses share many experiences with those affected by violence. Often the onset of the disease is sudden. The whole world of the patient is completely transformed by the disease and its potential threat to their quality of life and mortality. The illness becomes a traumatic event.
And all of the forces of self-healing found in traumatized people are activated in those with serious illness."
