The low level of stress symptomatology 3 months after the earthquake is consistent with previous research. The APA (2000) reports that about 50% of people with PTSD are usually completely recovered within 3 months of the traumatic event. In addition, all participants lived in Santiago, a city that resisted the earthquake in a good way, which was not affected by the tsunami, and which quickly returned its normal functioning after the event. This is reflected by the fact that participants reported little material damage caused by the earthquake (perceived magnitude) and only 1.8% of participants reported physical damage from the earthquake.
