Oral histories from 9/11 responders to the World Trade Center (WTC) attacks provide rich narratives about distress and resilience. Artificial Intelligence (AI) models promise to detect psychopathology in natural language, but they have been evaluated primarily in non-clinical settings using social media. This study sought to test the ability of AI-based language assessments to predict PTSD symptom trajectories among responders.

Participants were 124 responders whose health was monitored at the Stony Brook WTC Health and Wellness Program who completed oral history interviews about their initial WTC experiences. PTSD symptom severity was measured longitudinally using the PTSD Checklist (PCL) for up to 7 years post-interview. AI-based indicators were computed for depression, anxiety, neuroticism, and extraversion along with dictionary-based measures of linguistic and interpersonal style. Linear regression and multilevel models estimated associations of AI indicators with concurrent and subsequent PTSD symptom severity (significance adjusted by false discovery rate).

Cross-sectionally, greater depressive language (β = 0.32; p = 0.049) and first-person singular usage (β = 0.31; p = 0.049) were associated with increased symptom severity. Longitudinally, anxious language predicted future worsening in PCL scores (β = 0.30; p = 0.049), whereas first-person plural usage (β = −0.36; p = 0.014) and longer words usage (β = −0.35; p = 0.014) predicted improvement.

This is the first study to demonstrate the value of AI in understanding PTSD in a vulnerable population. Future studies should extend this application to other trauma exposures and to other demographic groups, especially under-represented minorities.

Current research of moral distress is mainly derived from challenges within high-resource health care settings, and there is lack of clarity among the different definitions. Disaster responders are prone to a range of moral challenges during the work, which may give rise to moral distress. Further, organizations have considered increased drop-out rates and sick leaves among disaster responders as consequences of moral distress. Therefore, initiatives have been taken to address and understand the impacts of moral distress and its consequences for responders. Since there is unclarity among the different definitions, a first step is to understand the concept of moral distress and its interlinkages within the literature related to disaster responders.

To examine how disaster responders are affected by moral challenges, systematic knowledge is needed about the concepts related to moral distress. This paper aims to elucidate how the concept of moral distress in disaster response is defined and explained in the literature.

The paper opted to systematically map the existing literature through the methods of a scoping review. The searches derived documents which were screened regarding specific inclusion criteria. The included 16 documents were analyzed and collated according to their definitions of moral distress or according to their descriptions of moral distress.

The paper provides clarity among the different concepts and definitions of moral distress within disaster response. Several concepts exist that describe the outcomes of morally challenging situations, centering on situations when individuals are prevented from acting in accordance with their moral values. Their specific differences suggest that to achieve greater clarity in future work, moral stress and moral distress should be distinguished.

Based on the findings, a conceptual model of the development of moral distress was developed, which displays a manifestation of moral distress with the interplay between the responder and the context. The overview of the different concepts in this model can facilitate future research and be used to illuminate how the concepts are interrelated.

To assess the psychological impact of a mass casualty incident (MCI) in a subset of personnel in a level I hospital.

Emergency department staff responded to an MCI in June 2017 in Turin, Italy by an unexpected sudden surge of casualties following a stampede (mass escape). Participants completed the Psychological Simple Triage and Rapid Treatment Responder Self-Triage System (PsySTART-R), which classified the potential risk of psychological distress in “no risk” versus “at risk” categorization and identified a range of impacts aggregated for the population of medical responders. Participants were administered a questionnaire on the perceived effectiveness of management of the MCI. Two months later, the participants were evaluated using the Hospital Anxiety and Depression Scale (HADS), the Kessler Psychological Distress Scale (K6), and the Posttraumatic Stress Disorder Checklist (PCL-5).

The majority of the responders were classified as “no risk” by the PsySTART-R; no significant differences on HADS, K6, and PCL-5 were found in the participants grouped by the PsySTART-R categories. The personnel acquainted to work in emergency contexts (emergency department and intensive care unit) scored significantly lower in the HADS than the personnel usually working in other wards. The number of positive PsySTART-R criteria correlated with the HADS depression score.

Most of the adverse psychological implications of the MCI were well handled and averted by the responders. A possible explanation could be related to factors such as the clinical condition of the victims (most were not severely injured, no fatalities), the small number of casualties (87) brought to the hospital, the event not being considered life-threatening, and its brief duration, among others. Responders had mainly to cope with a sudden surge in casualties and with organizational issues.

While the impact of disasters is strongly felt by those directly affected, they also have significant impact on the mental and physical health of rescue/relief workers and volunteers during the response phase of disaster management.

Semi-structured interviews were conducted with 11 experts in the field of disaster management from Nepal, inquiring specifically about the impact of the 2015 mega-earthquake on the mental and physical health of rescue/relief workers and volunteers. A thematic approach was used to analyze the results. These were used to assess the applicability of a previously developed conceptual framework which illustrates the hazards and risk factors affecting disaster response workers and the related hazard mitigation approaches.

The findings suggested a relationship between the type of injuries to responders and the type of disaster, type of responder, and vulnerability of location. The conceptual framework derived from literature was verified for its applicability with a slight revision on analysis of experts’ opinion based on particular context and disaster setting. Technical skills of responders, social stigma, governance, and the socio-economic status of the affected nation were identified as critical influencing factors to heath injuries and could be minimized utilizing some specific or collective measures targeted at the aforementioned variables. Some geographic and weather-specific risks may be challenging to overcome.

To prevent or minimize the hazards for disaster relief workers, it is vital to understand the variables that contribute to injuries. Risk minimization strategies should address these critical factors.

Disasters cause severe disruption to socio-economic, infrastructural, and environmental aspects of community and nation. While the impact of disasters is strongly felt by those directly affected, they also have significant impacts on the mental and physical health of relief/recovery workers and volunteers. Variations in the nature and scale of disasters necessitate different approaches to risk management and hazard reduction during the response and recovery phases.

Published articles (2010-2017) on the quantitative and quantitative relationship between disasters and the physical and mental health of relief/recovery workers and volunteers were systematically collected and reviewed. A total of 162 relevant studies were identified. Physical injuries and mental health impacts were categorized into immediate, short-term, and chronic conditions. A systematic review of the literature was undertaken to explore the health risks and injuries encountered by disaster relief workers and volunteers, and to identify the factors contributing to these and relating mitigation strategies.

There were relatively few studies into this issue. However, the majority of the scrutinized articles highlighted the dependence of nature and scope of injuries with the disaster type and the types of responders, while the living and working environment and socio-economic standing also had significant influence on health outcomes.

A conceptual framework derived from the literature review clearly illustrated several critical elements that directly or indirectly cause damage to physical and mental health of disaster responders. Pre-disaster and post-disaster risk mitigation approaches may be employed to reduce the vulnerability of both volunteers and workers while understanding the identified stressors and their relationships.

The purpose of this study was to investigate potential association between psychopathology and subjective evaluation of the experience of debriefing in disaster-exposed rescue and recovery workers.

Structured diagnostic interviews for DSM-III-R psychiatric disorders were conducted with 166 firefighters who served as rescue and recovery workers for the 1995 Oklahoma City bombing, who categorized their satisfaction with the debriefing on 4 levels. “Very dissatisfied” responses were examined for their association with post-traumatic stress disorder (PTSD) and with PTSD symptom groups.

Being “very dissatisfied” with the debriefing was significantly associated with the DSM-III-R avoidance and numbing group and with PTSD.

These findings suggest that debriefing may be an unsatisfactory intervention for people with prominent avoidance and numbing symptoms, such as those with PTSD. These individuals might be better served by referral directly to psychiatric treatment (Disaster Med Public Health Preparedness. 2018;12:718-722).

Post-traumatic symptomatology is one of the signature effects of the pernicious exposures endured by responders to the World Trade Center (WTC) disaster of 11 September 2001 (9/11), but the long-term extent of diagnosed Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) post-traumatic stress disorder (PTSD) and its impact on quality of life are unknown. This study examines the extent of DSM-IV PTSD 11–13 years after the disaster in WTC responders, its symptom profiles and trajectories, and associations of active, remitted and partial PTSD with exposures, physical health and psychosocial well-being.

Master's-level psychologists administered sections of the Structured Clinical Interview for DSM-IV and the Range of Impaired Functioning Tool to 3231 responders monitored at the Stony Brook University World Trade Center Health Program. The PTSD Checklist (PCL) and current medical symptoms were obtained at each visit.

In all, 9.7% had current, 7.9% remitted, and 5.9% partial WTC-PTSD. Among those with active PTSD, avoidance and hyperarousal symptoms were most commonly, and flashbacks least commonly, reported. Trajectories of symptom severity across monitoring visits showed a modestly increasing slope for active and decelerating slope for remitted PTSD. WTC exposures, especially death and human remains, were strongly associated with PTSD. After adjusting for exposure and critical risk factors, including hazardous drinking and co-morbid depression, PTSD was strongly associated with health and well-being, especially dissatisfaction with life.

This is the first study to demonstrate the extent and correlates of long-term DSM-IV PTSD among responders. Although most proved resilient, there remains a sizable subgroup in need of continued treatment in the second decade after 9/11.

Thousands of rescue and recovery workers descended on the World Trade Center (WTC) in the wake of the terrorist attack of September 11, 2001 (9/11). Recent studies show that respiratory illness and post-traumatic stress disorder (PTSD) are the hallmark health problems, but relationships between them are poorly understood. The current study examined this link and evaluated contributions of WTC exposures.

Participants were 8508 police and 12 333 non-traditional responders examined at the WTC Medical Monitoring and Treatment Program (WTC-MMTP), a clinic network in the New York area established by the National Institute for Occupational Safety and Health (NIOSH). We used structural equation modeling (SEM) to explore patterns of association among exposures, other risk factors, probable WTC-related PTSD [based on the PTSD Checklist (PCL)], physician-assessed respiratory symptoms arising after 9/11 and present at examination, and abnormal pulmonary functioning defined by low forced vital capacity (FVC).

Fewer police than non-traditional responders had probable PTSD (5.9% v. 23.0%) and respiratory symptoms (22.5% v. 28.4%), whereas pulmonary function was similar. PTSD and respiratory symptoms were moderately correlated (r=0.28 for police and 0.27 for non-traditional responders). Exposure was more strongly associated with respiratory symptoms than with PTSD or lung function. The SEM model that best fit the data in both groups suggested that PTSD statistically mediated the association of exposure with respiratory symptoms.

Although longitudinal data are needed to confirm the mediation hypothesis, the link between PTSD and respiratory symptoms is noteworthy and calls for further investigation. The findings also support the value of integrated medical and psychiatric treatment for disaster responders.
