The objective of this study was to examine the role that pre-existing psychopathology plays in developing PTSD after a natural disaster. Methods: The current study utilizes secondary data from a prospective 4-wave longitudinal cohort study (years 2003-2011) of Chilean adults (N=1,708). At baseline, participants completed the Composite International Diagnostic Interview (CIDI), a comprehensive psychiatric diagnostic instrument. In the midst of the study (2010), the sixth most powerful earthquake on record struck Chile. One year after the disaster, a modified version of the PTSD module of the CIDI was administered. Multivariable logistic regression analyses were performed to determine the most robust pre-disaster predictors of post-disaster PTSD. Results: The majority of our sample was female (75.9%), had a high school/college education (66.9%), and had at least one lifetime pre-disaster disorder (60.9%). After controlling for gender and age, pre-disaster PTSD (OR=1.74; 95%CI=1.15-2.65), Dysthymia (2.23; 1.41-3.53), non-affective Psychosis (2.80; 1.35-5.80), Panic disorder (2.51; 1.42-4.44), Agoraphobia (2.32; 1.27-4.24), Social Phobia (2.02; 1.16-3.52) and Specific Phobia (2.00; 1.45-2.76) were significant predictors of post-disaster PTSD. Compared to those with no disorder, those with pre-disaster PTSD plus 1-2 comorbid disorders (3.29; 1.77-6.12) and pre-disaster PTSD plus 3+ comorbid disorders (3.37; 1.76-6.45) were most at risk for developing post-disaster PTSD. Conclusions: This is the first study to prospectively examine which pre-disaster psychiatric disorders influence vulnerability to develop PTSD after a major traumatic event. Learning Areas: Clinical medicine applied in public health Diversity and culture Epidemiology Planning of health education strategies, interventions, and programs Public health or related research Social and behavioral sciences Learning Objectives: Evaluate the role that pre-existing psychopathology plays in developing PTSD after a natural disaster. Identify who is most at risk for developing PTSD. Keyword(s): Mental Health, Disasters Presenting author's disclosure statement: Qualified on the content I am responsible for because: I am an epidemiology PhD student at Brown University's School of Public Health. I was previously a mental health clinician (certified in Cognitive Behavioral Therapy), and am especially interested in PTSD from a psychiatric epidemiology and clinical standpoint.
