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.

Predictors of posttraumatic stress disorder and other psychological symptoms in trauma-exposed firefighters.

Firefighters are exposed to a range of potentially traumatic stressors, yet studies examining the impact of this exposure are equivocal. Although some studies suggest increased risk for mental health problems, others suggest unusual resilience. Type of assessment methodology may contribute to the lack of consistent findings. We assessed 142 trauma-exposed, professional firefighters utilizing a standardized clinical interview and self-report measures and found low rates of posttraumatic stress disorder (PTSD) diagnoses (4.2%), and depressive, anxiety, and alcohol-abuse symptoms. Frequency of trauma exposure did not predict psychological symptoms. Perceived social support, occupational stress, coping, as well as the interaction between perceived social support and self-blame were significant predictors of symptoms. Firefighters reporting low-perceived social support and high self-blame demonstrated the highest levels of clinically significant symptoms. These findings may inform education, treatment, and resilience training for emergency personnel.

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.

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.

Post‐traumatic stress disorder in Vietnam veterans: An experimental validation of the DSM‐III diagnostic criteria

The DSM-III criteria for post-traumatic stress disorder (PTSD) were derived clinically and have been substantiated in the literature only by self-report data while evaluation of these same criteria with more objective measures has been overlooked. This study provided a laboratory-based evaluation of the DSM-III criterion symptoms of PTSD with six symptoms of the disorder which were operationalized as cognitive, behavioral and psychophysiological measures. The responses of 16 Vietnam combat veterans who met the criteria for a PTSD diagnosis were compared to those of 16 well-adjusted combat veterans without PTSD. Dependent measures were obtained twice, following exposure to first control and then combat auditory stimuli. Results showed that five of the six measures were effective in differentiating the two combat veteran groups. These findings provided experimental support and construct validity for five DSM-III criteria of PTSD. The implications of these findings for the DSM-III-R PTSD diagnostic criteria are discussed.

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.

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.

Tobacco and alcohol use among firefighters during their first 3 years of service.

Firefighters constitute an understudied occupational group that are exposed to a great deal of occupational stress including potentially traumatic stress. As such, higher prevalence rates of posttraumatic stress disorder (PTSD) and substance use disorders have been observed within this population; however, very little is known about the trajectories of health-risk behaviors among firefighters in response to occupational stress over time. The present study enrolled 322 fire service recruits from 7 urban U.S. professional fire departments and followed them through the first 3 years of service. All enrollees were free of Axis I psychopathology at the time of baseline assessments, which were conducted while participants were still enrolled in the fire academy. We hypothesized that: (a) firefighters who used tobacco would have higher levels of alcohol use over time; and (b) firefighters with higher levels of traumatic exposure and mental health symptoms would evidence a stronger multisubstance risk pattern. Analyses provided support for our first hypothesis and revealed that depressive symptoms (but neither trauma exposure nor PTSD symptoms) moderated the alcohol-tobacco relationship. The clinical and public safety implications of these results are discussed.

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.
