The aim of this study was to assess the prevalence of posttraumatic stress disorder (PTSD) in undergraduate students after the Haiti earthquake on January 12, 2010, as well as to identify the risk factors involved in the development of PTSD symptoms in this sample. Evaluations concerning depression, anxiety, risk and protective factors, and PTSD symptoms were conducted in 246 Haitian undergraduate students enrolled in a Dominican private university. Results indicate a prevalence of 36% for PTSD 2 years after the earthquake, with a high prevalence also of depression (31.7%) and anxiety (21.1%). Some of the risk factors identified are being female, a history of psychiatric treatment, and the amount of personal and material losses. The instauration of crisis management and follow-up protocols after traumatic events was deemed to be needed. Further research is necessary to study the long-term effects of this tragedy, not only in undergraduate students, but also in the working class Haitian immigrants living in the Dominican Republic.
