Symptoms of depression and post-traumatic stress in a group of lightning strike victims

Abstract

IntroductionLightning strike victims often suffer repercussions. Although a lightning strike constitutes a severe traumatic event, there is a lack of data about potential psychological sequelae. This is precisely the context in which we assessed the prevalence of Post-Traumatic Stress Disorder (PTSD) and Major Depressive Episode (MDE) in a group of lightning strike victims. MethodsThe symptoms of peritraumatic dissociation were evaluated on the basis of the Peritraumatic Dissociative Experiences Questionnaire (PDEQ) whilst the Peritraumatic Distress Inventory (PDI) was used to assess symptoms of distress. PTSD and MDE diagnoses were evaluated using the MINI (Mini International Neuropsychiatric Interview). Symptom intensity was assessed using the self-report PTSD Checklist-Specific (PCLS) and the Beck Depression Inventory II (BDI II), respectively. ResultsForty-nine patients were enrolled in the study. As regards symptoms of depression, 28 patients (57.1%) reported a major depressive episode (MINI) including 10 (20.4%) of moderate intensity and 5 (10.2%) of severe intensity (BDI). In terms of PTSD symptoms, 13 patients (26.5%) reported probable PTSD (MINI) with a PCL-S score ≥ 45. A significant correlation was established between PDEQ and BDI II (Spearman correlation coefficient = 0.36, p = .012). A significant correlation was also found between PDI and PCLS (Spearman correlation coefficient = 0.43, p = .002). A further significant correlation was noted between PDEQ and PCLS (Spearman correlation coefficient = 0.31, p = .028). DiscussionThis study highlights the need for a multidisciplinary evaluation of lightning strike victims. Indeed, the prevalence of psychiatric disorders such as PTSD and MDE appears to be significant.
