Abstract The study aimed to identify the predictive relationship of sociodemographic variables and emotional symptoms related to post-traumatic stress disorder, depression, anxiety, and stress. A sample of 194 people who experienced an air disaster, average age of 32 years, participated in the survey. The instruments used were: Sociodemographic Data Questionnaire, Post-Traumatic Stress Disorder Checklist – Civilian Version, and Depression Anxiety and Stress Scale. A multiple regression analysis indicated that women participants were associated with post-traumatic stress disorder symptoms and those directly exposed to the disaster had higher odds ratios to develop post-traumatic stress disorder, depression, and stress symptoms. It is expected, with this information, to identify early the people who may be most vulnerable and contribute to the elaboration of intervention protocols.
