The March 11, 2004, train bombings in Madrid, Spain, caused the largest loss of life from a single terrorist attack in modern European history. We used a cross-sectional random digit dial survey of Madrid residents to assess the prevalence of posttraumatic stress disorder (PTSD) and major depression in the general population of Madrid 1 to 3 months after the March 11 train bombings. Of respondents 2.3% reported symptoms consistent with PTSD related to the March 11 bombings and 8.0% of respondents reported symptoms consistent with major depression. The prevalence of PTSD was substantially lower, but the prevalence of depression was comparable to estimates reported after the September 11 attacks in Manhattan. The findings suggest that across cities, the magnitude of a terrorist attack may be the primary determinant of the prevalence of PTSD in the general population, but other factors may be responsible for determining the population prevalence of depression.

Occupational stress is a significant problem throughout the modern world and a concern for many organizations (Flaxman & Bond, 2010). But it does not affect in the same manner the numerous existing occupations. Several studies have revealed that human services occupations, including teaching and health-care providing, are prone to high stress levels (Bermejo-Toro & Prieto-Ursúa, 2010;

We examined the relative contribution of specific components of multidimensional anxiety to cognitive biases in the processing of threat-related information in three experiments. Attentional bias was assessed by the emotional Stroop word color-naming task, interpretative bias by an on-line inference processing task, and explicit memory bias by sensitivity (d') and response criterion (β) from word-recognition scores. Multiple regression analyses revealed, first, that phobic anxiety and evaluative anxiety predicted selective attention to physical- and ego-threat information, respectively; cognitive anxiety predicted selective attention to both types of threat. Second, phobic anxiety predicted inhibition of inferences related to physically threatening outcomes of ambiguous situations. And, third, evaluative anxiety predicted a response bias, rather than a genuine memory bias, in the reporting of presented and nonpresented ego-threat information. Other anxiety components, such as motor and physiological anxiety, or interpersonal and daily-routines anxiety made no specific contribution to any cognitive bias. Multidimensional anxiety measures are useful for detecting content-specificity effects in cognitive biases.
