ABSTRACT

Flood research has used a variety of methods, yielding inconsistent findings. Universal definitions of illness are paramount to the science of psychiatric epidemiology of disasters. St. Louis area survivors (N = 162) of the Great Midwestern Floods of 1993 received a structured diagnostic assessment at 4 and 16 months postdisaster, with 88% follow-up. The purpose of the assessment was to examine predisaster and postdisaster rates of disorders and symptoms. Flood-related posttraumatic stress disorder was diagnosed in 22% and 16% at index and follow-up, respectively. Comorbidity with major depression determined whether the posttraumatic stress disorder would have remitted by 1 year later. Nearly one half of the men in the sample had a pre-existing alcohol use disorder. Virtually no new substance abuse followed the floods, and hence, substance abuse did not develop in response to the disaster or as part of coping with its aftermath. Somatization disorder was not observed; new somatoform symptoms represented a fraction of postflood somatic complaints. Findings are inconsistent with causal attribution of floods in the etiology of alcohol abuse and somatization. Methodological differences may account for much of the apparent discrepancy of these findings, with recent reports of increased alcohol use and somatic symptoms observed after other disasters.

    • "Long-term effects of disasters on mental health have been the focus of increasing interest in recent years. The majority of disaster survivors do not develop chronic reactions of distress and do not need professional help, whereas a sizeable minority may suffer for a prolonged period of time (Norris, Murphy, Baker, & Perilla, 2004; North, Kawasaki, Spitznagel, & Hong, 2004). Distressing psychological reactions are often most distinct during the first weeks after a traumatic event and gradually decrease during the following two years (Connor, Foa, & Davidson, 2006; Ford, Adams, & Dailey, 2007; Meewisse, Olff, Kleber, Kitchiner, & Gersons, 2011; Piyasil et al., 2007).

    ABSTRACT: Background: The characteristics of long-term trajectories of distress after disasters are unclear, since few studies include a comparison group. This study examines trajectories of recovery among survivors in comparison to individuals with indirect exposure. Methods: Postal surveys were sent to Swedish tourists, repatriated from the 2004 Indian Ocean tsunami (n=2268), at 1, 3, and 6 years after the tsunami to assess posttraumatic stress (PTS) and poor mental health. Items were used to ascertain high and moderate disaster exposure groups and an indirect exposure comparison group. Results: Long-term PTS trajectories were best characterized by a resilient (72.3%), a severe chronic (4.6%), a moderate chronic (11.2%) and a recovering (11.9%) trajectory. Trajectories reported higher levels of PTS than the comparison group. Exposure severity and bereavement were highly influential risk factors. Conclusions: These findings have implications regarding anticipation of long-term psychological adjustment after natural disasters and need for interventions after a single traumatic event with few secondary stressors.
