Disaster survivors in Japan must not only deal with physical trauma from earthquakes and tsunamis, but with psychological distress that can strike immediately, soon after or long after the event.
"There will be people who will be able to move back to how things were, and there's going to be a subset of people who are going to have more mental health issues," said Melissa Brymer, a clinical psychologist and director of the Terrorism and Disaster Programs for the National Center for Child Traumatic Stress at UCLA.
Those more at risk for psychological problems, Brymer said, include people with a history of anxiety or depression, those who have been in a previous disaster, people who have suffered great physical trauma, and children who have been separated from their families.
Post-traumatic stress disorder -- an anxiety disorder occurring after a traumatic event -- can strike some immediately or long after a stressful episode. But those who are more resilient -- people with strong social support systems, good family and friend relationships or strong religious convictions, for example -- usually do OK. "The majority of people do get better, and there are effective ways to help them," Brymer says.
Psychological counseling is no doubt being offered to victims and medical and emergency staff in Japan, she adds. "We also know that how a community supports itself can also be a mediating factor in how people deal with a disaster." Self-reliant communities that support their neighbors and schools tend to cope better.
