Health care needs, experiences, and satisfaction after terrorism: a longitudinal study of parents of survivors of the Utøya attack.

BACKGROUND: There is scarce knowledge on the health care follow-up of parents of terror attack survivors. This study focused on the mothers and fathers of survivors and examined (1) their perceived health care needs relative to their psychological reactions, physical health problems (unmet health care needs), and adaptation to work; (2) whether sociodemographic characteristics, health problems and social support were associated with unmet health care needs; and (3) how unmet health care needs, sociodemographic characteristics, and experiences with health services associated with overall dissatisfaction during the health care follow-up. METHODS: Interview and questionnaire data from three waves of the Utøya parent study were analyzed (n = 364). Chi-square tests and t- tests were used to compare unmet physical and psychological health care needs, sociodemographic factors and post-terror attack health reported by mothers and fathers. Logistic regression analyses were used to examine whether sociodemographic characteristics, unmet health care needs, and health care experiences were associated with overall dissatisfaction among mothers and fathers of the survivors during the health care follow-up. RESULTS: Among the mothers, 43% reported unmet health care needs for psychological reactions, while 25% reported unmet health care needs for physical problems. Among the fathers, 36% reported unmet health care needs for psychological reactions, and 15% reported unmet health care needs for physical problems. Approximately 1 in 5 mothers and 1 in 10 fathers reported "very high/high" needs for adaptation to work. Poorer self-perceived health, higher levels of posttraumatic stress and anxiety/depression symptoms, and lower levels of social support were significantly associated with reported unmet psychological and physical health care needs in both mothers and fathers. Parents with unmet health care needs reported significantly lower satisfaction with the help services received compared to parents whose health care needs were met. Low accessibility of help services and not having enough time to talk and interact with health care practitioners were associated with overall dissatisfaction with the help received. CONCLUSIONS: Our findings highlight that parents of terror-exposed adolescents are at risk of having unmet psychological and physical health care needs and thus need to be included in proactive outreach and health care follow-up programs in the aftermath of a terror attack.

The psychosocial aid response after the 22/03/2016 attacks in Belgium: a community case study.

Introduction: After the terrorist attacks, early psychosocial care is provided to people considered at risk of developing mental health issues due to the attacks. Despite the clear importance of such early intervention, there is very few data on how this is registered, who is targeted, and whether target-recipients accept such aid. Methods: Using registry data from the Centre General Wellbeingwork (CAW), a collection of centers in the regions Brussels and Flanders that provide psychosocial care, we examined the early psychosocial care response after the terrorist attacks of 22/03/2016 in Belgium. Results: In total, 327 people were listed to be contacted by the CAW, while only 205 were reached out to (62.7%). Most were contacted within a month (84.9%), and were victims of the attacks (69.8%). Overall, the majority was female (55.6%). Conclusion: Overall, target recipients were witnesses and survivors of the attacks, though a large proportion of people were not reached by the early outreach.

Post-what stress? A review of methods of research on posttraumatic stress during COVID-19.

BACKGROUND: Post-traumatic stress (PTS) was extensively investigated during the COVID-19 pandemic. However, numerous researchers have raised concerns regarding the adherence of many of these studies to the diagnostic criteria for PTSD as outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM) or the International Classification of Diseases (ICD). This review aimed to provide insight into the methodology of research on PTS during the COVID-19 pandemic. METHODS: Two independent reviewers examined a total of 1129 studies published between 1/01/2020 and 1/07/2023. The investigation focused on the scales employed to assess PTS, the diagnostic framework used (DSM or ICD), whether there was referral to an index-event in the PTS measurement and country where data collection took place. RESULTS: Among the 1129 studies, 70.0% did not provide any indication of an index-event to which PTS symptoms were attributed. Only 11.3% of the studies explicitly indicated an index-event associated with the PTS symptoms. Furthermore, 54.1% of the studies utilized scales based on DSM-IV criteria. Finally, the majority of PTS-studies had data collections in China, United States and Italy. CONCLUSION: A limited number of studies conducted during the COVID-19 pandemic reported use of an index-event in their PTS measurement. Furthermore, most studies used scales based on a previous iteration of the most used diagnostical system, namely the DSM. This delay in the implementation of new diagnostic criteria, may impair the clinical relevance of scientific studies.

The short-term impact of terrorism on public mental health: an emergency primary care approach.

BACKGROUND: Terrorist attacks commonly have mental health consequences for those directly affected. Existing research is, however, divided when it comes to how and whether terrorist attacks affect the general population's mental health. There is a need for studies investigating a broader range of mental health reactions to understand more about how different groups of the population are affected by terrorist attacks, while also illuminating important systemic factors. METHODS: In this study we investigated whether there was any change in the number of consultations with out-of-hours emergency primary care for psychological reactions in association with the 2011 terrorist attacks in Norway. Data covering the entire Norwegian population's primary care contacts in 2008-2013, where the reason for encounter was coded as psychological concerns or psychiatric disorders, were studied. A time series intervention analysis, using ARIMA modelling, was used to estimate whether there was indeed a change in healthcare utilisation associated with the terrorist attacks. RESULTS: The analysis uncovered an increase in contacts with emergency primary care by the overall population for mental health concerns associated with the terrorist attacks. When divided into groups according to geographical proximity to attacks, no significant change was found in the area closest to the attack in Oslo, whereas an increase was found for the rest of the country. There was also heterogeneity across different age groups. An increase was found among youths, young adults, and middle-aged people, but not the other age groups, and an increase was found for both men and women. CONCLUSIONS: These findings highlight the need for primary care services to be prepared to meet mental health reactions in the general population when planning for healthcare provision in the aftermath of terrorism. Simultaneously, it should be noted that needs may vary across different groups of the population.

Initiation of multiple-session psychological care in civilians exposed to the November 2015 Paris terrorist attacks.

BACKGROUND: Terrorist attacks can induce post-traumatic stress disorder (PTSD) and depression, which require multiple-session psychological care (MSPC). This study aims at investigating MSPC initiation and associated factors. METHODS: Data were collected from a web-based survey of civilians 8-12 months after their exposure to the November 2015 Paris terrorist attacks. Depression and partial and full PTSD were assessed using the Hospital Anxiety and Depression Scale and the PCL-5 checklist, respectively. Questionnaires collected data on socio-demographic variables, exposure to the attacks, psychological treatment history, social isolation, somatic problems, having received an outreach psychological support (OPS), consultations with a general practitioner, contact with an association for victims, MSPC initiation and, if not, reasons for not having initiated it. Logistic regressions were used to examine factors associated with MSPC initiation. RESULTS: Among the 450 respondents, 154 reported having initiated a MSPC after the attacks. Of the 134 who provided the MSPC initiation date, 50% did so during the first month. Among the respondents with at least one of the considered psychological disorders, 53% declared not having initiated yet a MSPC. The primary three reasons for not having initiated a MSPC among people with PTSD were "did not feel the need", "it was not the right time to talk about it", and "not offered". For people with at least one psychological disorder, MSPC initiation was associated with the number of somatic problems, type of exposure (witness, threatened, indirectly exposed), prior psychological treatment, being a woman, being in a relationship, having consulted a psychiatrist or a psychologist, having received an OPS, and being in contact with association for victims. CONCLUSION: The organization of adequate psychological care after a terror attack must take into account the need for healthcare that may emerge several months after the attack, and that witnesses seem less likely to receive MSPC than persons directly threatened despite their psychological disorder. Associations for victims and OPS seem to facilitate access to MSPC. Furthermore, our findings highlight the need to train physicians to screen for psychological disorders in persons exposed to terrorist attacks who present with somatic disorders.

[Psychosocial responses to collective trauma]. / Les réponses psychosociales aux traumatismes collectifs ­ un sujet international et transnational.

Both man-made and natural disasters are societal concerns of actuality that can take a heavy toll on people's health and well-being. It is paramount to understand how to prevent or reduce adverse psychological and social consequences in affected individuals and communities. There is currently an intention of better coordination across Europe to improve the handling of such cross-border health threats. Still, more insight is needed on how different countries respond to their population's psychosocial needs in the wake of disasters. Substantial differences in European countries' psychosocial responses to large-scale terrorist attacks are herein highlighted for Norway, France and Belgium. These differences emphasize the need to improve and harmonize the monitoring, evaluation and research on the provision of post-disaster psychosocial care and support in order to strengthen our capacities to deal with future emergencies.

Title: Les réponses psychosociales aux traumatismes collectifs ­ un sujet international et transnational. Abstract: Les catastrophes d'origine humaine ou naturelle constituent des préoccupations sociétales qui peuvent peser lourdement sur la santé et le bien-être. Il est primordial de comprendre comment prévenir ou réduire les conséquences psychologiques et sociales néfastes chez les individus et les communautés concernés. Afin de renforcer la gestion de ces menaces sanitaires transfrontalières, il existe actuellement une forte volonté d'améliorer la coordination à travers l'Europe. Il est donc essentiel de mieux comprendre comment les différents pays répondent actuellement aux besoins psychosociaux de leur population à la suite de catastrophes. De fait, notre étude met en évidence les différences substantielles qui existent dans les réponses psychosociales aux attentats terroristes à grande échelle dans trois pays européens (Norvège, France, Belgique). Elle montre qu'il sera nécessaire d'améliorer et d'harmoniser le suivi, l'évaluation et la recherche sur la fourniture de soins et de soutiens psychosociaux afin de renforcer nos capacités à faire face aux futures catastrophes.

Terror leaves adolescents behind: Identifying risk and protective factors for high-school completion among survivors of terrorism.

Terror exposure increases the risk of somatic and psychological health problems in survivors. Yet, knowledge of how such exposure affects survivors' ability to stay in school is lacking. This study examined whether exposure to the 2011 Utøya terrorist attack in Norway impacted survivors' ability to complete high school. Further, it aimed to identify important peri- and posttraumatic risk and protective factors. Interview data from the Utøya study, collected 4-5 months postterror, were linked to individual educational registry data for 265 survivors. Chi-square tests and ordinal logistic regression analyses were used to examine (a) high school completion among younger survivors (n = 185, age range: 13-18 years, 52.4% female) compared to both older survivors (i.e., who had the possibility of completing high school before the terror attacks; n = 80, age range: 19-21 years, 40.0% female) and the national average and (b) associations between high school completion and physical injury, posttraumatic stress symptoms (PTSS), somatic symptoms, and social support among younger survivors. Younger survivors were significantly less likely to complete high school on time. Among younger adolescents, physical injury, aOR = 0.36, 95% CI [0.16, 0.81]; higher-level PTSS, aOR = 0.54, 95% CI [0.33, 0.88]; and somatic symptoms, aOR = 0.51, 95% CI [0.29, 0.91], lowered the likelihood of on-time completion. Terror exposure in adolescence adversely affects long-term educational functioning in young survivors, which can severely hamper their future prospects. These findings reinforce the need for trauma-sensitive teaching and educator-provided support for adolescents exposed to trauma.

Preparing for the unexpected: a comparative study of policies addressing post-terror health reactions in Norway and France.

BACKGROUND: In the wake of terrorist attacks, protecting the health and psychosocial wellbeing of those affected and the general population, are important tasks for the healthcare system. The responses to such emergencies are often complex, including different phases and many actors, and may unveil insufficiencies that incite reforms to existing systems. Recently, initiatives have been promoted to strengthen cooperation and coordination regarding the governance of health threats in Europe. Comparative research is requested on how states prepare for health emergencies such as terrorist attacks. This study investigated how governments in two European countries with universal health coverage prepared to address the civilian population's health needs after terrorist attacks, and the factors that contributed to shaping their chosen approach. METHODS: Utilizing document analysis and Walt and Gilson's model for the analysis of health policy, national plans for post-terror health responses in Norway and France were studied with a focus on context, process, content, and actors. RESULTS: Whereas target groups for psychosocial care and certain measures were similar in both cases, the contents of prescribed policies and the actors responsible for enacting them differed. One of the most distinct differences was to what extent specialized mental healthcare was relied upon to provide psychosocial follow-up in the emergency phase. In the French approach, specialized mental healthcare practitioners, such as psychiatrists, psychologists and psychiatric nurses, provided early psychosocial support. In contrast, the Norwegian approach relied on interdisciplinary primary care crisis teams in the local municipalities to provide early psychosocial support, with further involvement of specialized mental healthcare if this was considered necessary. Historical, political, and systemic differences contributed to the variation in the countries' responses. CONCLUSIONS: This comparative study highlights the complexity and diversity of health policy responses to terrorist attacks across countries. Moreover, challenges and opportunities for research and health management in response to such disasters, including possibilities and potential pitfalls for the coordination of this work across Europe. An important first step could be to map out existing services and practices across countries to better understand if and how common core elements for psychosocial follow-up might be implemented internationally.

PTSD and Partial PTSD among First Responders One and Five Years after the Paris Terror Attacks in November 2015.

Following the Paris terror attacks in November 2015, a large number of first responders (FR) were mobilized and consequently were at risk of developing posttraumatic stress disorder (PTSD). Based on the ESPA 13 November survey, the objectives of this study were to 1) describe the prevalence of PTSD and partial PTSD in FR five years after the attacks, 2) describe the changes in PTSD and partial PTSD from one to five years after the attacks, and 3) examine factors associated with PTSD and partial PTSD five years after the attacks. Data were collected using an online questionnaire. PTSD and partial PTSD were measured using the Post-Traumatic Stress Disorder Checklist based on the DSM-5 (PCL-5). Gender, age, responder category, education level, exposure, mental health history, history of traumatic events, training, social support, concern about the COVID-19 epidemic, and somatic problems present after the attacks were all analyzed as potential factors associated with PTSD and partial PTSD using multinomial logistic regression. A total of 428 FR were included 5 years after the attacks, of which 258 had participated also 1 year after the attacks. Five years after the attacks, the prevalence of PTSD and partial PTSD were 8.6% and 22%, respectively. Presence of somatic problems after the attacks were associated with PTSD. Involvement in dangerous crime scenes was associated with a higher risk of partial PTSD. No awareness of psychological risks in the context of professional activity through specific training was associated with partial PTSD, in particular among participants aged 45 years or more. To mitigate PTSD for FR, monitoring mental health symptoms, providing mental health education, and providing treatment may be needed for several years after the attacks.

Threat through the Screen? Association between Proximity and/or Watching Media Coverage of a Terrorist Attack and Health.

INTRODUCTION: After terrorist attacks, media coverage of the attacks is extensive. There are some indications that there is an association between watching the media coverage and certain health reactions, both mental and somatic. Most studies occur in the United States and often months after the initial attack. In the current study, we investigated the terrorist attacks in Belgium on 22 March 2016. METHODS: An online cross-sectional survey was conducted one week after the attacks among the general population of Belgium. We measured hours of media watching of the terrorist attacks (hereafter media watching), adjusted scales of the Patient Health Questionaire-4 (PHQ-4) to measure mental symptoms and the Patient Health Questionaire-15 (PHQ-15) to measure somatic symptoms, proximity to Brussels (home, work and overall proximity) and background factors such as gender, age and level of education. Respondents were included if they answered the survey between 29 March 2016 and 5 April 2016. RESULTS: A total of 2972 respondents were included. Overall, media watching was significantly associated with both mental symptoms (p < 0.001) and somatic symptoms (p < 0.001), while controlling for age, gender, level of education and proximity. Watching more than three hours of media was associated with more mental and somatic symptoms (p < 0.001). Compared to proximity, media watching was, in general, a better association. For geographical factors, watching more than three hours of media indicated equally high scores for mental symptoms and somatic symptoms as work proximity (p = 0.015) and overall proximity to the attacks (p = 0.024). CONCLUSION: Media-watching is associated with acute health reactions after terrorist attacks. However, the direction of the relationship is unclear, as it might also be that people with health issues seek out more media.

Short-Term Psychological Support for Civilians Exposed to the January 2015 Terrorist Attacks in France.

INTRODUCTION: Following a terrorist attack, responses to a psychosocial disaster range from low-intensity initiatives to high-intensity treatment. Some studies described post-disaster psychosocial services and planning across Europe. However, little is known about the psychosocial support (PS) actually delivered after terrorist attacks. STUDY OBJECTIVE: This study assesses prevalence and the factors associated with not receiving short-term PS among terror-exposed people with probable mental health disorders following the January 2015 terrorist attacks in France. METHODS: This study used data from the first wave of a longitudinal survey conducted six months after the attacks. Prevalence and factors associated with not receiving PS were described in the immediate period (48 hours), the early post-immediate period (48 hours-one week), and the medium-term (over one week) using a robust Poisson regression for each of the three periods. RESULTS: Nearly one-half of the participants (N = 189) did not receive PS in any period (46.6% in the immediate period, 45.5% in the early post-immediate period, and 54.5% in the medium-term). In each period, not receiving PS was associated with not being very close to the attack sites. Not receiving PS in the immediate period was also associated with being a direct witness (DW) rather than being directly threatened (DT) and not having support in daily life; in the early post-immediate period, not receiving PS was associated with not having a peri-traumatic dissociation experience and being followed for a psychological problem before the attacks; and in the medium-term period, it was associated with perceived social isolation. CONCLUSION: The characteristics of the terror exposure and social support seemed to influence presence or absence of PS after the terrorist attack and highlight the need for strategies to reach out to people regardless of the type of exposure.

Healthcare utilization after mass trauma: a register-based study of consultations with primary care and mental health services in survivors of terrorism.

BACKGROUND: Knowledge on healthcare utilization after mass trauma is needed to strengthen the public health preparedness to such incidents. Using register-based data, this study had a unique opportunity to investigate how young survivors' use of primary care physicians (PCP) and mental health services (MHS) changed after a terrorist attack. METHODS: We examined register-based data on PCP and MHS consultations among 255 survivors (52% male) of the 2011 Utøya youth camp attack in Norway 3 years before and after the attack, and their reason for encounter with the PCP according to the International Classification for Primary Care (ICPC- 2). RESULTS: The PCP and MHS consultation rates (CR) were higher in female than male survivors both acutely and at long-term. The mean yearly CRs increased from 2.25 to 4.41 for PCP and 1.77 to 13.59 for MHS the year before and after the attack in female survivors, and from 1.45 to 3.65 for PCP and 1.02 to 11.77 for MHS in male survivors. The third year post-attack CRs for PCP were 3.55 and 2.00; and CRs for MHS were 5.24 and 2.30 in female and male survivors, respectively. Among female survivors, 76% consulted PCP and 12% MHS the year preceding the attack; post-attack 93% consulted PCP and 73% MHS the first year; decreasing to 87 and 40% the third year. Among male survivors, 61% consulted PCP and 7% MHS the year preceding the attack; post-attack 86% consulted PCP and 61% MHS the first year, and 67 and 31% the third year. As for PCP consultations, there was a particular increase in psychological reasons for encounter following the attack. CONCLUSIONS: This study indicates that it is important to anticipate an increased healthcare utilization several years following mass trauma, particularly of MHS. Both PCP and MHS practitioners played important roles in providing healthcare for psychological problems in young survivors of terrorism in a country with universal and largely publicly financed healthcare and a gatekeeping system. The healthcare utilization could be different in countries with other health systems or psychosocial care responses to mass trauma.

Remote training as a common tool for the different professionals involved in the acute phase after terror attacks across Europe: Perspectives from an expert panel.

The acute response after a terror attack may have a crucial impact on the physical and psychological wellbeing of the victims. Preparedness of the professionals involved in the acute response is a key element to ensure effective interventions, and can be improved through trainings. Today in Europe there is a recognized lack of inter-professional and international trainings, which are important, among others, to respond to the needs and the rights of victims affected by a terrorist attack in another country than their home country. In this paper we report the perspectives of an expert panel composed by different categories of professionals on the possible role of interprofessional trainings provided remotely. The experts discussed the pertinence of remote trainings for professionals involved in the acute response of a terror attack, and highlighted their Strengths, Weaknesses, Opportunities and Threats (SWOT analysis). We concluded that, while remote trainings cannot replace in-person trainings, they may be useful to share knowledge about the role and the organization of the different categories of professionals, thus potentially improving response coordination, and to easily share good practices across professionals and countries.

Psychosocial care responses to terrorist attacks: a country case study of Norway, France and Belgium.

BACKGROUND: The international terrorism threat urges societies to invest in the planning and organization of psychosocial care. With the aim to contribute to cross-national learning, this study describes the content, target populations and providers of psychosocial care to civilians after terrorist attacks in Norway, France and Belgium. METHODS: We identified and reviewed pre- and post-attack policy documents, guidelines, reports and other relevant grey literature addressing the psychosocial care response to terrorist attacks in Oslo/Utøya, Norway on 22 July 2011; in Paris, France on 13 November 2015; and in Brussels, Belgium on 22 March 2016. RESULTS: In Norway, there was a primary care based approach with multidisciplinary crisis teams in the local municipalities. In response to the terrorist attacks, there were proactive follow-up programs within primary care and occupational health services with screenings of target groups throughout a year. In France, there was a national network of specialized emergency psychosocial units primarily consisting of psychiatrists, psychologists and psychiatric nurses organized by the regional health agencies. They provided psychological support the first month including guidance for long-term healthcare, but there were no systematic screening programs after the acute phase. In Belgium, there were psychosocial intervention networks in the local municipalities, yet the acute psychosocial care was coordinated at a federal level. A reception centre was organized to provide acute psychosocial care, but there were no reported public long-term psychosocial care initiatives in response to the attacks. CONCLUSIONS: Psychosocial care responses, especially long-term follow-up activities, differed substantially between countries. Models for registration of affected individuals, monitoring of their health and continuous evaluation of countries' psychosocial care provision incorporated in international guidelines may strengthen public health responses to mass-casualty incidents.

Media Exposure and Post-traumatic Stress Symptoms in the Wake of the November 2015 Paris Terrorist Attacks: A Population-Based Study in France.

The intense mass media coverage of the Paris terrorist attacks on November 13, 2015 exposed a majority of the French population to the attacks. Prior research has documented the association between media exposure to terrorism and post-traumatic stress symptoms (PTSS). The present study replicated and extended these findings in a French sample. A population-based sample (N = 1,760) was drawn from a national web-enabled panel in June 2016. Hours of attack-related media exposure (i.e., TV-watching, viewing internet images, engaging in social media exchanges) in the 3 days following the attacks were assessed. Multivariate regression models, adjusting for gender, age, direct exposure (i.e., witnessing in person or knowing someone injured or killed), residential area, social support, pre-attack mental health service utilization, and other adverse life events, examined the association between media exposure and PTSS (assessed using the self-report PCL-5). Compared to those reporting less than 2 hours of daily attack-related television exposure, those reporting 2-4 hours (ß = 3.1, 95% CI = 0.8-5.3) or >4 hours (ß = 4.7, 95% CI = 2.0-7.4) of media exposure reported higher attack-related PTSS. This finding was replicated with social media use: those with moderate (ß = 3.2, 95% CI = 0.9-5.5) or high (ß = 6.8, 95% CI = 1.9-11.7) use reported higher PTSS than those reporting no use. Subanalyses demonstrated that media exposure and PTSS were not associated in those directly exposed to the attacks. Results highlight the potential public health risk of extensive mass media exposure to traumatic events.

Use of mental health supports by civilians exposed to the November 2015 terrorist attacks in Paris.

BACKGROUND: The use of mental health supports by populations exposed to terrorist attacks is rarely studied despite their need for psychotrauma care. This article focuses on civilians exposed to the November 2015 terrorist attacks in Paris and describes the different combinations of mental health supports (MHSu) used in the following year according to type of exposure and type of mental health disorder (MHD). METHODS: Santé publique France conducted a web-based survey of civilians 8-11 months after their exposure to the November 2015 terrorist attacks in Paris. All 454 respondents met criterion A of the DSM-5 definition of post-traumatic stress disorder (PTSD). MHD (anxiety, depression, PTSD) were assessed using the PCL-5 checklist and the Hospital Anxiety and Depression Scale. MHSu provided were grouped under outreach psychological support, visits for psychological difficulties to a victims' or victim support association, consultation with a general practitioner (GP), consultation with a psychiatrist or psychologist (specialist), and initiation of regular mental health treatment (RMHT). Chi-squared tests highlighted differences in MHSu use according to type of exposure (directly threatened, witnessed, indirectly exposed) and MHD. Phi coefficients and joint tabulations were employed to analyse combinations of MHSu use. RESULTS: Two-thirds of respondents used MHSu in the months following the attacks. Visits to a specialist and RMHT were more frequent than visits to a GP (respectively, 39, 33, 17%). These were the three MHSu most frequently used among people with PTSD (46,46,23%), with depression (52,39,20%), or with both (56,58, 33%). Witnesses with PTSD were more likely not to have RMHT than those directly threatened (respectively, 65,35%). Outreach support (35%) and visiting an association (16%) were both associated with RMHT (Phi = 0.20 and 0.38, respectively). Very few (1%) respondents initiated RMHT directly. Those who indirectly initiated it (32%) had taken one or more intermediate steps. Visiting a specialist, not a GP, was the most frequent of these steps. CONCLUSION: Our results highlight possibilities for greater coordination of mental health care after exposure to terrorist attacks including involving GP for screening and referral, and associations to promote targeted RMHT. They also indicate that greater efforts should be made to follow witnesses.

Non-participation and attrition in a longitudinal study of civilians exposed to the January 2015 terrorist attacks in Paris, France.

BACKGROUND: Non-participation and attrition are rarely studied despite being important methodological issues when performing post-disaster studies. A longitudinal survey of civilians exposed to the January 2015 terrorist attacks in Paris, France, was conducted 6 (Wave 1) and 18 months (Wave 2) after the attacks. We described non-participation in Wave 1 and determined the factors associated with attrition in Wave 2. METHODS: Multivariate logistic regression models were used to compare participants in both waves with those who participated in the first wave only. Analyses were performed taking the following factors into account: socio-demographic characteristics, exposure to terror, peri-traumatic reactions, psychological support, perceived social support, impact on work, social and family life, and mental health disorders. Characteristics of new participants in Wave 2 were compared with participants in both waves using a chi-square test. RESULTS: Of the 390 persons who were eligible to participate in the survey, 190 participated in Wave 1 (participation rate: 49%). The most frequently reported reason for non-participation was to avoid being reminded of the painful event (32%, n = 34/105). In Wave 2, 67 were lost to follow-up, 141 people participated, of whom 123 participated in Wave 1 (re-participation rate: 65%) and 18 were new. Attrition in Wave 2 was associated with socio-demographic characteristics (age, French origin) and location during the attacks, but not with terror exposure or mental health disorders. Compared with those who participated in both waves, new participants declared less social and psychological support since the attacks. CONCLUSIONS: Attrition at 6 months was not associated with exposure to terror or mental health disorders, which indicates that any bias in future analyses on IMPACTS on mental health outcomes will be limited. Our findings suggest the importance of adapting similar surveys for people of foreign origin and of improving strategies to avoid attrition of younger people, for example by using social media, peers, and the educational environment. The present study also revealed that a high level of exposure to terror and a lack of social and psychological support after a terrorist event could impede individuals' participation in similar surveys in the short term.

Factors associated with PTSD and partial PTSD among first responders following the Paris terror attacks in November 2015.

During the evening of 13 November 2015, the deadliest terror attacks in France in recent times occurred in the Paris area. Overall, 130 people were killed, 643 were physically injured and several thousands were psychologically impacted. Thousands of first responders, including health professionals, firefighters, affiliated volunteers and police officers were mobilized that night and during the subsequent weeks. The aims of our study were to measure the psychological impact on first responders in terms of post-traumatic stress disorder (PTSD) and partial PTSD as well as associated factors 12 months after the 13 November 2015 terrorist attacks. First responders who had intervened during the night and/or the aftermath of the terror attacks had the possibility of answering a web-based study 8-12 months after the attacks. They satisfied criterion A of the DSM 5 definition of PTSD. PTSD and partial PTSD were measured using the PCL-5. Gender, age, educational level, exposure, first responder category, mental health and traumatic event history, training and social support were all analysed as potential factors associated with PTSD and partial PTSD, using multinomial logistic regression. Overall, 663 participants were included in this analysis. Prevalence of PTSD in our sample went from 3.4% among firefighters to 9.5% among police officers and prevalence of partial PTSD from 10.4% among health professionals to 23.2% among police officers. Low educational level and social isolation were associated with PTSD and partial PTSD. Intervention on unsecured crime scenes and lack of training were associated with PTSD. Special attention should be given to first responders living in social isolation, those with low educational levels and those who intervene in unsecured crime scenes. Education and training about the potential mental health consequences of mass trauma intervention should be developed.
