Negative Emotionality Interacts with Trauma Exposure to Prospectively Predict Posttraumatic Stress Disorder Symptoms During Firefighters' First 3 Years of Service.

Firefighters (FFs) protect the public despite significant risks to their health and well-being stemming from frequent trauma exposure and other occupational stressors. A minority of FFs develop posttraumatic stress disorder (PTSD) or related mental health problems, whereas most remain remarkably resilient despite enormous stress. This points toward substantial variability in responses to traumatic stress among FFs. Personality, particularly negative emotionality (NEM), has been shown to predict the development of PTSD in other trauma-exposed populations, yet has not been prospectively studied in relation to PTSD in FFs. The aim of this secondary analysis from a broader study of mental health in FFs was to test whether preemployment NEM predicted PTSD symptom severity over time by influencing how FFs respond to traumatic experiences. In this first prospective study of the development of PTSD symptoms in professional FFs, 322 FFs were recruited from seven urban fire academies across the United States and followed over their first 3 years of fire service. We assessed NEM during the fire academy as well as trauma exposure and both self-reported and clinician-rated PTSD symptoms at 1-, 2-, and 3-year follow-ups. Level of trauma exposure and NEM predicted PTSD symptoms over time, and NEM moderated the effect of trauma exposure on clinician-rated PTSD symptoms across both trauma exposure measures at 1- and 3-year follow-ups, f2 = .03-.10, but not at 2-year follow-up nor for self-reported PTSD symptoms. These findings indicate that NEM, assessed upon entry into a high-risk occupation, is useful in predicting PTSD symptom development.

Differences in drinking patterns, occupational stress, and exposure to potentially traumatic events among firefighters: predictors of smoking relapse.

BACKGROUND AND OBJECTIVES: Despite the increased awareness regarding the risks of cigarette smoking, this behavior continues to be a serious public health concern. As such, the goal of the current study was to examine risk factors for smoking relapse among individuals employed through fire service. METHODS: In this report, drinking changes, trauma exposure, and occupational stress were compared among firefighters (N = 81) who reported a relapse to cigarette smoking (n = 27), a lifetime former history of smoking (n = 27), or no history of smoking (n = 27). Mechanisms behind tobacco relapse occurring after employment in fire service were explored. RESULTS: Firefighters who relapsed to smoking, when compared to their nonsmoking peers, had higher rates of weekly alcohol consumption throughout their first year of fire service and had greater increases in drinking from preacademy to postacademy. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: Gaining a better understanding of these behaviors within this understudied and high-risk population may provide valuable information that can be used in designing future relapse prevention strategies as well as smoking cessation interventions.

Career versus volunteer firefighters: Differences in perceived availability and barriers to behavioral health care.

Due to occupational stress and exposure to potentially traumatic events, firefighters are at an increased risk for the development of many behavioral health conditions. While volunteer and career firefighters represent two distinct subgroups, little research has examined differences in the availability of, and barriers to, behavioral health care between these populations. This study examined perceived availability and barriers to behavioral health care services among 2,156 career and 227 volunteer firefighters. Volunteer firefighters were less likely to report availability of drug and alcohol or family and couple services, but more likely to report availability of a trained peer support system and follow-up care compared to career firefighters. Volunteer firefighters were over five times more likely to consider cost a barrier to accessing behavioral health services compared to career firefighters; however, they were less likely to report lack of support from leadership, fear of breach of confidentiality, and clinicians who are unaware of work culture as barriers. Volunteer and career firefighters were equally likely to report stigma as a barrier. These findings have important implications for understanding how to strengthen departmental resources and to design targeted interventions to increase access to behavioral health services.

A prospective study of firefighters' PTSD and depression symptoms: The first 3 years of service.

Objective: Firefighters are an important sample of convenience to study traumatic exposure and symptom development. This study assessed trauma exposure inside and outside of fire service, diagnosed posttraumatic stress disorder (PTSD) and associated disorders using clinical interviews and self-report measures, then tested the hypothesis that trauma exposure would predict distress in firefighters over the first 3 years in service. Method: In total, 322 professional firefighter recruits were assessed during academy training and through their first 3 years of service. Diagnostic assessments were conducted by psychologists annually, and symptom checklists were completed by telephone every 4 months. Results: Firefighter recruits were exposed to approximately nine potentially traumatic events (PTEs) in the first 3 years of fire service, with 66% of these events occurring in the line of duty. Very few (3%) developed diagnoses of PTSD, major depression, or generalized anxiety disorder. Models of distress supported a trait model of distress. Distress was stable within individuals over time, and although those reporting more distress also reported more trauma exposure, variation in distress over time was not predicted by trauma exposure. Conclusions: Professional firefighters experience frequent exposure to potentially traumatic events during their early careers. This exposure, although large, does not result in a large proportion of mental health diagnoses. Distress was consistent and low, which provides evidence of the resilient nature of those selecting a career in emergency service. Future work is needed to understand the disconnection between the current rigorously collected prospective data and the existing literature regarding the increased risk of PTSD and associated disorders in fire service.

Behavioral health programs in fire service: Surveying access and preferences.

Due to the stressful nature of the job, firefighters are likely to be at increased risk for behavioral health problems. This study examined the access, attitudes, and preferences of a large sample of professional firefighters (N = 2,156) toward behavioral health services using an online survey. Overall, 81% of participants reported that they had access to behavioral health services through their fire service department, although smaller departments were less likely to offer such services. Despite available programs within fire service, firefighters most commonly reported that they would seek outside help from their spouse/family (67%) or private professional services (60%). Firefighters with fewer years in service were more likely to go to a spouse/family member, coworker, or officer for help, whereas those with more years were more likely to seek private professional services. Few firefighters directly stated that stigma would prevent them from using behavioral health services, yet a large percentage of firefighters (68%) reported that they would not recommend these services to colleagues, and stigma-related barriers were still among the most significant reported. "Clinicians who understand firefighter work culture" was rated as one of the most important components to a successful behavioral health program; a lack thereof rated as one of the most significant barriers. Offered together, these findings suggest that greater exploration of stigma in fire service is warranted, and attention toward training culturally competent clinicians to work with firefighters is needed.

The Influence of Exposure to Natural Disasters on Depression and PTSD Symptoms among Firefighters.

Introduction Firefighters represent an important population for understanding the consequences of exposure to potentially traumatic stressors. Hypothesis/Problem The researchers were interested in the effects of pre-employment disaster exposure on firefighter recruits' depression and posttraumatic stress disorder (PTSD) symptoms during the first three years of fire service and hypothesized that: (1) disaster-exposed firefighters would have greater depression and PTSD symptoms than non-exposed overall; and (2) depression and PTSD symptoms would worsen over years in fire service in exposed firefighters, but not in their unexposed counterparts. METHODS: In a baseline interview, 35 male firefighter recruits from seven US cities reported lifetime exposure to natural disaster. These disaster-exposed male firefighter recruits were matched on age, city, and education with non-exposed recruits. RESULTS: A generalized linear mixed model revealed a significant exposure×time interaction (e coef =1.04; P<.001), such that depression symptoms increased with time for those with pre-employment disaster exposure only. This pattern persisted after controlling for social support from colleagues (e coefficient=1.05; P<.001), social support from families (e coefficient=1.04; P=.001), and on-the-job trauma exposure (coefficient=0.06; e coefficient=1.11; P<.001). Posttraumatic stress disorder symptoms did not vary significantly between exposure groups at baseline (P=.61). CONCLUSION: Depression symptoms increased with time for those with pre-employment disaster exposure only, even after controlling for social support. Posttraumatic stress disorder symptoms did not vary between exposure groups.

Anxiety, anxiety disorders, tobacco use, and nicotine: a critical review of interrelationships.

Smoking is highly prevalent across most anxiety disorders. Tobacco use increases risk for the later development of certain anxiety disorders, and smokers with anxiety disorders have more severe withdrawal symptoms during smoking cessation than smokers without anxiety disorders. The authors critically examined the relationships among anxiety, anxiety disorders, tobacco use, and nicotine dependence and reviewed the existing empirical literature. Future research is needed to better understand the interrelationships among these variables, including predictors, moderators, and mechanisms of action. Increased knowledge in these areas should inform prevention efforts as well as the development and improvement of smoking cessation programs for those with anxiety and other psychiatric disorders.

Social support, stress, and suicidal ideation in professional firefighters.

OBJECTIVE: To hypothesize that social support may protect against the effect of firefighter stress on suicidal ideation. METHODS: Overall, 334 firefighters completed measures of occupational stress, social support, and suicidal ideation. RESULTS: At high levels of social support, no association was observed between occupational stress and suicidal ideation (φ = -.06, ns); however, when social support was low, occupational stress showed a positive association with suicidal ideation (φ = .16, p < .05). CONCLUSIONS: The association between occupational stress and suicidal ideation may be reduced by social support. Further research on this topic is warranted.

Internal consistency, test-retest reliability, and predictive validity for a Likert-based version of the Sources of occupational stress-14 (SOOS-14) scale.

This study examined the psychometric properties of a Likert-based version of the Sources of Occupational Stress-14 (SOOS-14) scale. Internal consistency for the SOOS-14 ranged from 0.78-0.84, whereas three-month test-retest reliability was 0.51. In addition, SOOS-14 scores were prospectively associated with symptoms of PTSD and depression at a three-month follow-up assessment.

Disaster mental health workers responding to Ground Zero: one year later.

The current study examined anniversary reactions in mental health disaster relief workers following traumatic exposure at the site of the World Trade Center terrorist attacks. Despite relatively low levels of symptom reporting, workers endorsed an increase in both negative mood symptoms and functional impairment at the one-year anniversary of their traumatic exposure (compared to 6 months postexposure). For those individuals who met at least partial criteria for PTSD immediately following exposure, overall self-reported PTSD symptoms tended to increase from 6 to 12 months. This tendency resulted specifically from an increase in hyperarousal symptoms. Although few endorsed symptoms at clinical levels, our results demonstrate that disaster relief workers may experience an increase in symptomatology at the anniversary of their traumatic exposure.
