“…Although several studies have reported the effects of negative emotions such as anxiety, PTSD, and acute combat stress on cognitive function [66,93,94], very few prospective studies have been conducted in people under significant long-term stress. Our findings have important implications for individuals who experience major longterm stress, such as students who face major academic stress.…”

Chronic stress affects brain function, so assessing its hazards is important for mental health. To overcome the limitations of behavioral data, we combined behavioral and event-related potentials (ERPs) in an attention network task. This task allowed us to differentiate between three specific aspects of attention: alerting, orienting, and execution. Forty-one participants under chronic stress and 31 non-stressed participants were enrolled. On the performance level, the chronically stressed group showed a significantly slower task response and lower accuracy. Concerning ERP measures, smaller cue-N1, cue-N2, and larger cue-P3 amplitudes were found in the stressed group, indicating that this group was less able to assign attention to effective information, i.e., they made inefficient use of cues and had difficulty in maintaining alerting. In addition, the stressed group showed larger target-N2 amplitudes, indicating that this group needed to allocate more cognitive resources to deal with the conflict targets task. Subgroup analysis revealed lower target-P3 amplitudes in the stressed than in the non-stressed group. Group differences associated with the attention networks were found at the ERP level. In the stressed group, excessive depletion of resources led to changes in attention control. In this study, we examined the effects of chronic stress on individual executive function from a neurological perspective. The results may benefit the development of interventions to improve executive function in chronically stressed individuals.

“…Internal consistency of the DERS-16 total score in the current sample was excellent (α = .97; Cronbach, 1951). As consistent with past work (Hallion et al, 2018; Paltell et al, 2019), the DERS-16 total score was used as an index of ERD.…”

The present investigation examined the associations among thwarted belongingness (TB), emotion regulation difficulties (ERD), and posttraumatic stress disorder (PTSD) symptom severity among firefighters. First, the associations of TB and ERD with PTSD symptom severity were evaluated. Second, the indirect effect of TB on PTSD symptom severity through ERD was examined. The sample included 246 trauma-exposed firefighters ( M age = 40.21, SD = 9.93, 93.1% male) who completed an online questionnaire battery. Results demonstrate significant, positive associations among TB, ERD, and PTSD symptom severity; and an indirect effect of TB on PTSD symptom severity through heightened ERD (β = 0.17; CI [0.08, 0.29]). Alternate indirect effect models were also significant, underscoring the potentially bidirectional associations of these variables. These findings suggest that there is merit in investigating the role of interpersonal factors and ERD among firefighter populations to better understand PTSD symptomatology. Clinical and empirical implications are discussed.

“…Other cognitive factors associated with increased PTSI include difficulties with emotion regulation (Paltell et al, 2019), hopelessness (Violanti et al, 2016), trauma-related cognitions (Bryant & Guthrie, 2005), the feeling of entrapment (Lee, 2019), and anxiety sensitivity (Angehrn et al, 2020; Boffa et al, 2018; Patterson et al, 2014). Resilience is associated with less severe mental health symptoms in PTE-exposed PSP (Kim et al, 2018).…”

Police, firefighters, and emergency medical technicians and paramedics are frequently exposed to potentially traumatic events (PTE) in their work as public safety personnel (PSP). PTE are a risk factor for posttraumatic stress disorder, depression, anxiety, substance abuse, and suicidal ideation. This systematic rapid scoping review summarizes evaluation research on psychosocial interventions to reduce the negative consequences of exposure to work-related PTE on the mental health of PSP. Articles were identified using PubMed and PsycInfo. Publications from January 1, 2013, to December 1, 2020, were retained because the research published before 2013 was covered by other reviews. We identified 601 unique documents; 30 met preliminary eligibility criteria; and 18 were retained. Most studies were limited to police officers and firefighters. Participants exposed to prevention measures reported improvements of symptoms of depression, burnout, anxiety, sleep problems, and well-being. Most articles identified factors that may hinder or facilitate the use of program components. Studies on ways to support PSP recently affected by a PTE are lacking. There are little data on the efficacy of prevention programs in reducing the prevalence of mental disorders associated with PTE. More studies should focus on identifying participant characteristics and intervention components that influence program use, adherence, and efficacy. Realistic evaluations combined with participatory research could help address important knowledge gaps.
