  Background Work-related post-traumatic stress disorder (PTSD) is an important condition encountered by many occupational health practitioners. Aims To carry out an in-depth review of the research on occupational groups that are at particular risk of developing work-related PTSD. Methods A literature search was conducted in the databases OVID MEDLINE, OVID Embase, Ovid PsycINFO, ISI Web of Science and CSA Health and Safety Science Abstracts. Results Professionals such as police officers, firefighters and ambulance personnel often experience incidents that satisfy the stressor criterion for the PTSD diagnosis. Other professional groups such as health care professionals, train drivers, divers, journalists, sailors and employees in bank, post offices or in stores may also be subjected to work-related traumatic events. Work-related PTSD usually diminishes with time. Conclusions Mental health problems prior to the traumatic event and weak social support increase the risk of PTSD. Prevention of work-related PTSD includes a sound organizational and psychosocial work environment, systematic training of employees, social support from colleagues and managers and a proper follow-up of employees after a critical event.

  This study analyzed trajectories of initial stress and long-term mental health after the 1980 North Sea oil rig disaster. A growth-mixture model of the survivors' stress manifestations in the first 8 weeks (Posttraumatic Stress Scale, [PTSS-10]) and general mental health in 1980, 1981, 1985, and 2007 (General Health Questionnaire, [GHQ-20]) was estimated. Survivors' GHQ-scores in 1985 and 2007 were contrasted to those of a comparison group. Four trajectories were identified among survivors. The resilient (n = 43) displayed initially moderate stress that rapidly declined. The recovery (n = 10), chronic (n = 8), and relapse (n = 9) showed initially stable high stress scores, but the long-term mental health differed. Early screening may identify those at long-term risk.

  The present study aimed at predicting posttraumatic stress 5 and 27 years after the North Sea oil rig disaster. The predictions were based on the initial levels of stress responses and the early recovery as reported in 1980. The Posttraumatic Stress Scale (PTSS) was used at 3 measure points. From 1980, data from 69 survivors were used in latent growth modeling. Follow-up studies included 65 survivors and 85 matched unexposed oil-rig workers in 1985; and 47 and 62 in 2007. In 1985, the survivors had higher total PTSS scores and more frequent endorsements on most single PTSS-items than the comparison group. In 2007, a few single items remained different. The initial levels of stress responses and the early recovery rate predicted the long-term outcomes after 5 and 27 years. Initial screenings may be helpful in the early detection of posttraumatic stress in the very long-term perspective.

  Background: Early trauma-focused cognitive-behavioural therapy (TFCBT) holds promise as a preventive intervention for people at risk of developing chronic post-traumatic stress disorder (PTSD). The aim of this review was to provide an updated evaluation of the effectiveness of early TFCBT on the prevention of PTSD in high risk populations. Methods: We performed a systematic literature search in international electronic databases (MEDLINE, EMBASE, PsycINFO, CENTRAL, CINAHL, ISI and PILOTS) and included randomised controlled trials comparing TFCBT delivered within 3 months of trauma, to alternative interventions. All included studies were critically appraised using a standardised checklist. Two independent reviewers selected studies for inclusion and assessed study quality. Data extraction was performed by one reviewer and controlled by another. Where appropriate, we entered study results into meta-analyses. Results: Seven articles reporting the results of five RCTs were included. All compared TFCBT to supportive counselling (SC). The study population was patients with acute stress disorder (ASD) in four trials, and with a PTSD diagnosis disregarding the duration criterion in the fifth trial. The overall relative risk (RR) for a PTSD diagnosis was 0.56 (95% CI 0.42 to 0.76), 1.09 (95% CI 0.46 to 2.61) and 0.73 (95% CI 0.51 to 1.04) at 3–6 months, 9 months and 3–4 years post treatment, respectively. A subgroup analysis of the four ASD studies only resulted in RR = 0.36 (95% CI 0.17 to 0.78) for PTSD at 3–6 months. Anxiety and depression scores were generally lower in the TFCBT groups than in the SC groups. Conclusion: There is evidence for the effectiveness of TFCBT compared to SC in preventing chronic PTSD in patients with an initial ASD diagnosis. As this evidence originates from one research team replications are necessary to assess generalisability. The evidence about the effectiveness of TFCBT in traumatised populations without an ASD diagnosis is insufficient.

  Surveys investigated the perceived threat of radioactive fallout and public coping following a "silent disaster" (Chernobyl) across Europe. Survey data from national representative samples in 12 European countries are compiled, 6 months and 2 years after the accident, across 12 countries. Exposure to information about the accident, and perception of the consequences of Chernobyl as a health threat, were significantly related to the level of fallout in each country. Another significant relationship was found between the level of fallout in these 12 countries and the proportion of respondents who reported having taken countermeasures. Information challenges for the authorities are highlighted

  A sample of 1,624 Norwegian veterans from the UNIFIL (United Nations Interim Force in Lebanon) was investigated on average 6.6 years after service, completing a questionnaire focusing on stress exposure and posttraumatic stress reactions. The prevalence of posttraumatic stress disorder (measured by the Posttraumatic Symptom Scale [PTSS-10]) was 5% overall, but 16% in the subgroup of personnel having been prematurely repatriated from UNIFIL. Multiple regression analyses showed that the following variables made separate and significant contributions to the explained variance of the PTSS-10: Service stress exposure, perceived lack of meaningfulness with respect to the military mission, and stressful life-events in life after service. These factors explained 25% (overall sample) and 37% (repatriated sample) of the variation in the posttraumatic symptom score.

  Etter en alvorlig stressbelastning har kroppen sin egen måte å håndtere stressymptomene på. Metastudier og alle internasjonale retningslinjer for behandling av PTSD fraråder rutinemessig debriefing som en tidligforebyggende strategi for mennesker utsatt for en potensielt traumatiserende hendelse. Obligatorisk debriefing bør opphøre.

  Bakgrunn: Denne rapporten er del to av en kunnskapsoppsummering om effekter av psykososiale tiltak ved kriser, katastrofer og ulykker, og ble bestilt av Sosial- og helsedirektoratet i september 2004. Problemstilling: Virker psykososiale tiltak iverksatt inntil ett år etter ulykker og kriser på traumerelaterte psykiske lidelser og funksjonssvikt? Metode: Vi søkte systematisk i internasjonale forskningsdatabaser, valgte ut studier etter gitte kriterier, vurderte den metodiske kvaliteten ved hjelp av sjekklister, og oppsummerte resultatene. Ut fra søkene inkluderte vi 10 systematiske oversikter, 29 randomiserte kontrollerte studier (RCTer) og 10 ikke-randomiserte effektvurderinger. De systematiske oversiktene og de ikke-randomiserte effektvurderingene har vi kun beskrevet, mens vi har analysert RCTene grundigere. De 29 relevante RCTene var publisert i til sammen 34 forskjellige artikler, og omhandlet blant annet psykologisk debriefing(PD), kognitiv atferdsterapi (CBT), gruppetiltak, rådgivningsprogram og tiltak rettet mot traumatiserte barn. Resultater: Metaanalyser viste at PD ikke virker bedre enn ikke å gjøre noe. Effekten av PD var målt med utfallene posttraumatisk stresslidelse (PTSD), posttraumatiske stressymptomer, angst og depresjon etter 3-6 måneder og 1-3 år. Videre viste metaanalysene at CBT virker bedre enn andre behandlinger og bedre enn ikke å tilby behandling. Pasienter som fikk CBT hadde halvparten så stor risiko for å ha en PTSD-diagnose etter 3-6 måneder som kontrollgruppene. Etter 9 måneder var risikoen en tredjedel så stor, og etter 3-4 år en fjerdedel så stor som i kontrollgruppen For andre relevante tiltak fant vi for lite god forskning til at vi kan vurdere nytteverdien av tiltakene. Konklusjoner: • kognitiv atferdsterapi i fire uker eller mer kan forebygge traumerelaterte psykiske lidelser • Psykologisk debriefing har ingen dokumentert nytte

  Sosial- og helsedirektoratet ga i september 2004 Kunnskapssenteret i oppdrag å lage en kunnskapsoppsummering om effekten av psykososiale tiltak ved kriser, ulykker og katastrofer. Kunnskapssenteret opprettet en ekstern ekspertgruppe bestående av fem personer til å bistå i arbeidet med kunnskapsoppsummeringen. Oppdraget ble avgrenset til bare å omfatte tiltak ved store ulykker (transport- /industriulykker) og katastrofer. Vi gjennomførte systematiske søk i internasjonale forskningsdatabaser, utvelgelse av studier etter gitte kriterier, kvalitetsvurdering av studier ved hjelp av sjekklister og oppsummering av dokumentasjonen i standardiserte skjemaer. Resultatene fra de inkluderte studiene oppsummerte vi kvalitativt.
