During recent years attention has been drawn to the importance of psychosocial support to victims of accidents and disasters. Post-traumatic stress disorder seems to be more frequent than earlier believed, and early psychosocial assistance is thought to reduce the psychological effects of the traumatic experience. The authors describe the psychosocial work, as it was organized at Haukeland Hospital, after a shipwreck. Experiences with mobile medical teams with stress competence are also discussed.
