Emergency medical workers’ distress and recovery patterns after a mass shooting were related to their coping behaviors and routine daily activities. This longitudinal repeated measures study assessed 31 emergency medical workers’ psychological and psychosomatic symptoms self-rated for the weeks before, those just after, and one full month after the shooting. Coping behaviors and time in creative activities were related to increased acute distress; recovery was related to more time in constructive activities. Thinking about the incident was related to higher acute distress but better recovery on several SCL9OR scales. Exercise predicted recovery on Obsessive-Compulsive and Hostility scales. Studies evaluating emergency workers’ reactions to and recovery from critical incidents should use repeated measures designs, should assess short-term recovery, and should distinguish among symptoms.
