Teenagers who live in areas affected by terrorism can often become depressed. Researchers from Ben-Gurion University in Israel studied teenagers who had been indirectly affected by a suicide bombing. None of them had directly witnessed the bombing but some had heard it, others knew people who had suffered physical or emotional damage, or had seen media reports of the attack. Before the bombing the teenagers had already completed a questionnaire as part of another study and the researchers were able to use this data to see which factors existing before the bombing helped to prevent depression after it. The researchers found that the more socially happy the adolescents were before the bombing the less depressed they became afterwards.
