title: [Screening for posttraumatic stress disorder in people affected by the 2010 earthquake in Chile.]
abstract: The authors conducted an assessment of post-traumatic stress disorder screening in the Chilean population following the February 2010 earthquake, based on the Post Earthquake Survey with a multistage sample of 24,982 individuals over 18 years of age, applying the Davidson Trauma Scale. Multivariate analysis was performed with significance set at p<0.05. Prevalence of positive screening for post-traumatic stress disorder was 11% for the country as a whole, but reached 30% at lower-level disaggregation. The logistic regression model for post-traumatic stress disorder identified the following risk factors: belonging to a low-income family, having suffered damage to the household, a history of health problems in the previous month, and female gender (p<0.05). Family coping with the earthquake proved to be a protective factor as compared to other social or neighborhood groups, and more years of schooling were also protective (p<0.05). Positive screening for posttraumatic stress disorders revealed clear social inequalities.
