Background Nearly 20 years after the terrorist attacks of September 11, 2001, multiple studies have documented the adverse mental consequences among World Trade Center (WTC) rescue, recovery, and clean-up workers. However, scarce research has examined mental health stigma and barriers to care in WTC-exposed individuals, and no known study has examined whether rates of endorsement may differ between police and "nontraditional" responders, the latter comprising a heterogeneous group of workers and volunteers. Objective To identify the prevalence and correlates of mental health stigma and barriers to care in WTC responders. Methods Mental health stigma and barriers to care and their correlates were examined in 6,777 police and 6,272 nontraditional WTC responders. Results Nontraditional responders endorsed more stigma or barriers to care concerns than police responders. Within a subsample who screened positive for a psychiatric disorder, police were more likely than nontraditional responders to endorse "concerns that negative job consequences might result" (17.9% vs. 9.1%), while nontraditional responders were more likely to endorse "I don't know where to go to find counseling services" (18.4% vs.6.6%). Within this subsample, mental health service need and more severe WTC-related posttraumatic stress disorder symptoms were associated with increased likelihood of endorsing stigma or barriers; pre-9/11 psychiatric history and non-Hispanic Black race/ethnicity were associated with lower likelihood of endorsing stigma or barriers. Conclusions Results of this study underscore the burden of mental health stigma and barriers to care in WTC responders, and highlight the need for targeted interventions to address these concerns and promote mental healthcare utilization in this population.

PURPOSE. Nearly two decades after the 9/11 attacks on the World Trade Center (WTC), the prevalence of mental disorders remains elevated among traditional (e.g., police) and non-traditional (e.g., construction workers) responders who were involved in the WTC rescue, recovery, and clean-up efforts. To date, however, scarce research has examined factors associated with perceived need for mental health care, which is critical to promoting engagement in mental health treatment in this population. METHODS. Data were analyzed from 16,170 WTC responders, including 8,881 police responders and 7,289 non-traditional responders, who completed their first annual health monitoring visit with the WTC Health Program an average of 6.5 years after 9/11/2001. Predisposing, enabling, and need-based factors associated with perceived need for mental health care were examined using multivariable logistic regression analyses. RESULTS. Nearly half (48.7%) of non-traditional responders and a fifth (20.6%) of police responders reported a need for mental health care. The most common perceived needs were for psychotropic medication, individual psychotherapy, and stress management counseling. Predisposing (e.g., female gender) and need-based factors (e.g., WTC-related posttraumatic stress disorder) predicted perceived need for mental health care in both groups. Among non-traditional responders, Hispanic ethnicity and current suicidal ideation were additionally associated with this outcome. CONCLUSIONS. Non-traditional WTC responders are substantially more likely than police WTC responders to perceive a need for mental health treatment. Characterization of factors associated with perceived need for treatment can help inform population-based outreach and monitoring efforts designed to promote engagement in mental health treatment in WTC responders.

BackgroundPost-traumatic stress disorder (PTSD) in response to the World Trade Center (WTC) disaster of 11 September 2001 (9/11) is one of the most prevalent and persistent health conditions among both professional (e.g. police) and non-traditional (e.g. construction worker) WTC responders, even several years after 9/11. However, little is known about the dimensionality and natural course of WTC-related PTSD symptomatology in these populations.MethodData were analysed from 10 835 WTC responders, including 4035 police and 6800 non-traditional responders who were evaluated as part of the WTC Health Program, a clinic network in the New York area established by the National Institute for Occupational Safety and Health. Confirmatory factor analyses (CFAs) were used to evaluate structural models of PTSD symptom dimensionality; and autoregressive cross-lagged (ARCL) panel regressions were used to examine the prospective interrelationships among PTSD symptom clusters at 3, 6 and 8 years after 9/11.ResultsCFAs suggested that five stable symptom clusters best represent PTSD symptom dimensionality in both police and non-traditional WTC responders. This five-factor model was also invariant over time with respect to factor loadings and structural parameters, thereby demonstrating its longitudinal stability. ARCL panel regression analyses revealed that hyperarousal symptoms had a prominent role in predicting other symptom clusters of PTSD, with anxious arousal symptoms primarily driving re-experiencing symptoms, and dysphoric arousal symptoms primarily driving emotional numbing symptoms over time.ConclusionsResults of this study suggest that disaster-related PTSD symptomatology in WTC responders is best represented by five symptom dimensions. Anxious arousal symptoms, which are characterized by hypervigilance and exaggerated startle, may primarily drive re-experiencing symptoms, while dysphoric arousal symptoms, which are characterized by sleep disturbance, irritability/anger and concentration difficulties, may primarily drive emotional numbing symptoms over time. These results underscore the importance of assessment, monitoring and early intervention of hyperarousal symptoms in WTC and other disaster responders.

Trajectories of disaster-related posttraumatic stress disorder (PTSD) symptoms are often heterogeneous, and associated with common and unique risk factors, yet little is known about potentially modifiable psychosocial characteristics associated with low-symptom and recovering trajectories in disaster responders. A total of 4487 rescue and recovery workers (1874 police and 2613 non-traditional responders) involved during and in the aftermath of the unprecedented World Trade Center (WTC) attacks, were assessed an average of 3, 6, 8, and 12 years post-9/11/2001. Among police responders, WTC-related PTSD symptoms were characterized by four trajectories, including no/low-symptom (76.1%), worsening (12.1%), improving (7.5%), and chronic (4.4%) trajectories. In non-traditional responders, a five-trajectory solution was optimal, with fewer responders in a no/low-symptom trajectory (55.5%), and the remainder in subtly worsening (19.3%), chronic (10.8%), improving (8.5%), and steeply worsening (5.9%) trajectories. Consistent factors associated with symptomatic PTSD trajectories across responder groups included Hispanic ethnicity, pre-9/11 psychiatric history, greater WTC exposure, greater medical illness burden, life stressors and post-9/11 traumas, and maladaptive coping (e.g., substance use, avoidance coping). Higher perceived preparedness, greater sense of purpose in life, and positive emotion-focused coping (e.g., positive reframing, acceptance) were negatively associated with symptomatic trajectories. Findings in this unique cohort indicate considerable heterogeneity in WTC-related PTSD symptom trajectories over 12 years post-9/11/2001, with lower rates of elevated PTSD symptoms in police than in non-traditional responders. They further provide a comprehensive risk prediction model of PTSD symptom trajectories, which can inform prevention, monitoring, and treatment efforts in WTC and other disaster responders.
