Canadian Public Safety Personnel (e.g., correctional workers, dispatchers, firefighters, paramedics, and police) are regularly exposed to potentially traumatic events, some of which are highlighted as critical incidents warranting additional resources. Unfortunately, available Canadian public safety personnel data measuring associations between potentially traumatic events and mental health remains sparse. The current research quantifies estimates for diverse event exposures within and between several categories of public safety personnel. Participants were 4,441 public safety personnel (31.7% women) in 1 of 6 categories (i.e., dispatchers, correctional workers, firefighters, municipal/provincial police, paramedics, and Royal Canadian Mounted Police). Participants reported exposures to diverse events including sudden violent (93.8%) or accidental deaths (93.7%), serious transportation accidents (93.2%), and physical assaults (90.6%), often 11+ times per event. There were significant relationships between potentially traumatic event exposures and all mental disorders. Sudden violent death and severe human suffering appeared particularly related to mental disorder symptoms, and therein potentially defensible as critical incidents. The current results offer initial evidence that (a) potentially traumatic event exposures are diverse and frequent among diverse Canadian public safety personnel; (b) many different types of exposure can be associated with mental disorders; (c) event exposures are associated with diverse mental disorders, including but not limited to posttraumatic stress disorder, and mental disorder screens would be substantially reduced in the absence of exposures; and (d) population attributable fractions indicated a substantial reduction in positive mental disorder screens (i.e., between 29.0 and 79.5%) if all traumatic event exposures were eliminated among Canadian public safety personnel.

Public Safety Personnel (PSP; e.g., correctional workers and officers, firefighters, paramedics, police officers, and public safety communications officials (e.g., call center operators/dispatchers)) are regularly exposed to potentially psychologically traumatic events (PPTEs). PSP also experience other occupational stressors, including organizational (e.g., staff shortages, inconsistent leadership styles) and operational elements (e.g., shift work, public scrutiny). The current research quantified occupational stressors across PSP categories and assessed for relationships with PPTEs and mental health disorders (e.g., anxiety, depression). The participants were 4820 PSP (31.7% women) responding to established self-report measures for PPTEs, occupational stressors, and mental disorder symptoms. PPTEs and occupational stressors were associated with mental health disorder symptoms (ps < 0.001). PSP reported substantial difficulties with occupational stressors associated with mental health disorder symptoms, even after accounting for diverse PPTE exposures. PPTEs may be inevitable for PSP and are related to mental health; however, leadership style, organizational engagement, stigma, sleep, and social environment are modifiable variables that appear significantly related to mental health.

experience an elevated risk for mental disorders due to inherent work-related stress. Several programs have been designed to increase mental health knowledge, intending to reduce stigma, and increase mental health service helpseeking (e.g., resilience training); however, extant programs have not demonstrated sustained improvements for PSP mental health. The current study assessed levels of mental health knowledge, stigma, and service use intentions in a sample of Canadian PSP and compared trends to published estimates of mental health symptoms across PSP categories to inform future programming. Methods: PSP completed questionnaires assessing mental health knowledge, stigma against coworkers with mental illness, and professional service use intentions. Correlations among variables and one-way analyses of variance were conducted to assess differences among categories. PSP were categorized into six categories for comparison: communication officials, correctional workers, firefighters, municipal/provincial police, paramedics, and Royal Canadian Mounted Police (RCMP). Results: There were significant differences between categories for each variable. Correctional workers reported the most mental health knowledge, least stigma, and highest intentions to use mental health services, and the highest positive screens for mental disorders. Conversely, firefighters reported the lowest mental health knowledge, highest stigma, and lowest willingness to seek professional help, and the lowest prevalence of positive screens for mental disorders. Discussion: The results contrast previously hypothesized associations among mental health variables where education, stigma reduction, and help-seeking have been expected to improve mental health. The discrepant results offer potentially critical information for organizational policies to better support PSP. Individuals reporting mental health symptoms may be a more appropriate target audience for intervention strategies, given the possible, crucial role personal experience plays in increasing mental health knowledge, and ultimately, encouraging help-seeking.

Anxiety levels have increased for several decades, despite objective indicators of historically unprecedented safety. A perceived inability to tolerate uncertainty or distress motivates individuals experiencing anxiety to engage in safety behaviors. Mobile phones provide unrestricted access to safety cues intended to reduce uncertainty and therein anxiety; however, recurrent engagement in reassurance seeking behaviors paradoxically increases anxiety. The current research was designed to assess whether self-reported intolerance of uncertainty (IU) levels may have been increasing and, if so, whether the increases correlate positively with mobile phone penetration and Internet usage. A cross-temporal meta-analysis was conducted using data from 52 North American studies exploring IU as well as social indicator data from several public sources. A statistically significant increase in IU levels occurred from 1999 to 2014, correlated with increases in mobile phone penetration and Internet usage. As hypothesized, IU levels appeared to be increasing over time and the increases correlate positively with mobile phone penetration and Internet usage. The results support the possibility that mobile phones increase reassurance seeking, acting as safety cues, and reducing spontaneous, everyday exposures to uncertainty, which may ultimately potentiate psychopathology by increasing IU and anxiety. Subsequent experimental research to assess for causality appears warranted. Limitations and directions for future research are presented.

Background Public safety personnel (PSP; e.g., correctional workers and officers, firefighters, paramedics, police officers, public safety communications officials) are regularly exposed to potentially traumatic events and considerable uncertainty as part of their employment. Canadian PSP screen positively for mental disorders at much higher rates than the general population. Intolerance of uncertainty (IU) and anxiety sensitivity (AS) are empirically-supported vulnerability factors associated with the development and maintenance of mental disorders. Methods The present study was designed to assess IU and AS across PSP-a population regularly encountering uncertainty-with and without mental disorders (n = 4304; 33.3% women), and across normative clinical, community, and undergraduate samples. Further, the study examined the relationship between IU and AS and mental disorders among PSP. Results There were significant differences across groups on IU and AS scores (ps < .001). All PSP, with and without a positive screen for a mental disorder, reported lower IU and AS than clinical samples; however, PSP without mental disorders reported lower IU and AS than all other groups (ps < .001). Conclusion Increased resilience or the development of coping skills to manage regular exposures to uncertain threat may help explain why PSP reported low levels of IU and AS despite higher prevalence of mental disorders. Implications for PSP training and treatment are discussed.
